Abstract:
This paper discusses an integrated perceptual system for intelligent robots. Robots should be able to perceive environments flexibly enough to realize intelligent behavior. We focus on a perceptual system based on the perceiving-acting cycle discussed in ecological psychology. The perceptual system we propose consists of a retinal model and a spiking-neural network realizing the perceiving-acting cycle concept. We apply our proposal to a robot arm with a threedimensional (3D)-range camera. We verified the feasibility of the perceptual system using a single input such as depth or luminance information. Our proposal integrates different perceptual elements for improving the accuracy of perception. Experimental results showed that our proposal perceives the targeted dish accurately by integrating different perceptual elements using the 3D-range camera.

Abstract:
Above threshold, two superimposed sinusoidal gratings of the same spatial frequency (eg 1 cycle deg−1), of equal moderate contrast (eg C1 = C2 = 6%), and with orientations of ±45°, usually look like a compound structure containing vertical and horizontal edges (ie a blurred checkerboard). These feature orientations are very different from the dominant filter orientations in a wavelet-type (eg simple-cell) transform of the stimulus, and so present a serious challenge to conventional models of orientation coding based on labelled linear filters. Previous experiments on perceived structure in static plaids have led to the view that the outputs of tuned spatial filters are combined in a stimulus-dependent way, before features such as edges are extracted. Here an adaptation paradigm was used to investigate the cross-channel interactions that appear to underlie the spatial-filter-combination process. Reported are two aftereffects of selective adaptation: (i) adaptation to a 1 cycle deg−1 plaid whose component orientations are intermediate to those in a 1 cycle deg−1 test plaid ‘breaks’ perceptual combination of the components in the test plaid; (ii) adapting to a 3 cycles deg−1 plaid whose component orientations match those in a 1 cycle deg−1 test plaid facilitates perceptual combination of the components in the test plaid. The results are taken as evidence that spatial channels remote from those most responsive to a test plaid play a crucial role in determining whether the test plaid segments or coheres perceptually.

Abstract:
The challenge in human–robot interaction is to build an agent that can act upon human implicit statements, where the agent is instructed to execute tasks without explicit utterance. Understanding what to do under such scenarios requires the agent to have the capability to process object grounding and affordance learning from acquired knowledge. Affordance has been the driving force for agents to construct relationships between objects, their effects, and actions, whereas grounding is effective in the understanding of spatial maps of objects present in the environment. The main contribution of this paper is to propose a methodology for the extension of object affordance and grounding, the Bloom-based cognitive cycle, and the formulation of perceptual semantics for the context-based human–robot interaction. In this study, we implemented YOLOv3 to formulate visual perception and LSTM to identify the level of the cognitive cycle, as cognitive processes synchronized in the cognitive cycle. In addition, we used semantic networks and conceptual graphs as a method to represent knowledge in various dimensions related to the cognitive cycle. The visual perception showed average precision of 0.78, an average recall of 0.87, and an average F1 score of 0.80, indicating an improvement in the generation of semantic networks and conceptual graphs. The similarity index used for the lingual and visual association showed promising results and improves the overall experience of human–robot interaction.

Abstract:
The main purpose of this study was to examine the relative contribution of respiratory mechanical factors and the increased metabolic cost of locomotion to exertional breathlessness in obese women. We examined the relationship of intensity of breathlessness to ventilation (V̇e) when exertional oxygen uptake (V̇o2) of obesity was minimized by cycle exercise. Eighteen middle-aged (54 ± 8 yr, mean ± SD) obese [body mass index (BMI) 40.2 ± 7.8 kg/m2] and 13 age-matched normal-weight (BMI 23.3 ± 1.7 kg/m2) women were studied. Breathlessness at higher submaximal cycle work rates was significantly increased (by ≥1 Borg unit) in obese compared with normal-weight women, in association with a 35–45% increase in V̇e and a higher metabolic cost of exercise. Obese women demonstrated greater resting expiratory flow limitation, reduced resting end-expiratory lung volume (EELV)(by 20%), and progressive increases in dynamic EELV during exercise: peak inspiratory capacity (IC) decreased by 16% (0.39 liter) of the resting value. V̇e/V̇o2 slopes were unchanged in obesity. Breathlessness ratings at any given V̇e or V̇o2 were not increased in obesity, suggesting that respiratory mechanical factors were not contributory. Our results indicate that in obese women, recruitment of resting IC and dynamic increases in EELV with exercise served to optimize operating lung volumes and to attenuate expiratory flow limitation so as to accommodate the increased ventilatory demand without increased breathlessness.

Abstract:
Aeronautical critical decision making (ACDM) can be the main factor determining whether an incident turns into an accident. With hindsight it is easy to establish where poor decisions were made. In order to gain a better understanding of ACDM it is necessary to investigate local rationality: to establish why the actions and assessments undertaken by an operator made sense to them at the time. The Perceptual Cycle Model (PCM) was used as the theoretical framework to investigate ACDM. The PCM describes the reciprocal, cyclical, relationship that exists between an operator and their work environment; depicting the interaction between internally held mental schemata and externally available environmental information as equal contributors to decisions and actions. It is argued that the acknowledgement of this interaction sets the PCM apart from other models of decision making. A literature review established that the PCM is a suitable framework to model ACDM. Two case studies, one an accident analysis and one a critical incident interview, demonstrated that the PCM was sensitive in establishing that the interaction of both schemata and world information influenced decision making processes. Subsequent research developed the PCM as an explanatory framework in three key ways. First, the construct validity of the model was explored. A counter-cycle (not depicted in the original model) was found and this was attributed to automatic, skill-based, behaviour characteristic of experts. Second, the PCM was extended by the development of a bespoke taxonomy to provide a more detailed description of ACDM. This demonstrated the importance of different PCM concepts in different phases of critical decision making. This work also led to the development of an interview schedule to elicit perceptual cycle data. Third, the PCM was applied to the study of teams. This novel application of the model demonstrated how teams function in a distributed perceptual cycle, whereby the actions of one team member become world information for the other. The overall findings are discussed in light of their potential theoretical, methodological and practical applications.

Full text
Abstract:
The assessment of ventilatory threshold (Tvent) and maximal oxygen consumption (VO2max) are routine laboratory procedures, yet there are few studies that have directly compared these measurements during different modes of exercise in children. Therefore, the purpose of this study was to compare the physiological and perceptual responses at Tvent and V02max during treadmill and cycle ergometry in prepubertal male children. Ten subjects (M ± SD, 10.2 + 1.3 yrs.) performed a graded exercise test to maximal effort on a treadmill and a cycle ergometer. The order of testing was counterbalanced. The treadmill protocol began at 3.0 mph and 2% grade and progressed in one minute stages. Similarly, the cycle protocol began at 30 watts (W) and progressed 10 W•min-1. For both protocols, each stage was designed to elicit an approximately 3.5 ml-kg-I- min-1 change in V02. In addition, finger stick blood samples were taken at 2, 3, and 5 minutes post exercise in order to assess maximal blood lactate (La) level. Mean V02max on the treadmill (58.2 ± 6.9 ml•kg-l.min-1) was greater (P < 0.05) as compared to the cycle (51.7 ± 7.7ml.kg-'•min-1), with the average difference and the cycle ergometer, V02max is a function of the testing modality. LiKewise, the V02 at Tvent is dependent on the mode of exercise, while Tvent expressed as a percentage of VO2max is independent of mode of exercise. The perceptual responses at Tvent appear to be linked to a percentage of V02max, rather than an absolute V02.

Full text
Abstract:
The transition from cycling to running has been identified as one of the key determinants of success in triathlon, as it has been suggested that the cycle may affect subsequent running efficiency such that running performance is significantly altered or reduced. It is also suggested that athletes more adapted to the transition itself, rather than purely running or cycling, may be more efficient during the post-cycle running bout. The current study sought to investigate the effects of prior cycling on subsequent selected biomechanical, physiological and perceptual responses of three different athlete groups. Subjects were selected on the basis of their sporting background, and were divided into three groups – triathletes, cyclists and runners. Experimentation required subjects to perform a seven minute treadmill running protocol at 15km.h⁻¹, during which biomechanical (EMG, Stride rate, Stride length, Vertical acceleration), physiological (HR, VO₂, EE) and perceptual (RPE) responses were recorded. After resting, subjects were required to perform a twenty minute stationary cycle at 70% of maximal aerobic power (previously determined), immediately followed by a second seven minute treadmill running protocol during which the same data were collected and compared to those collected during the first run. Biomechanical responses indicate that the cycle protocol had no effect on the muscle activity or vertical acceleration responses of any of the three subject groups, while the triathlete group significantly altered their gait responses in order to preserve running economy. The triathlete group was the least affected when considering the physiological responses, as running economy was preserved for this group. The runner and cyclist groups were significantly affected by the transition, as running economy decreased significantly for these groups. Perceptual responses indicate that athletes more experienced with the transition may find the transition from cycling to running to be easier than those inexperienced in this transition. It is apparent that a high intensity cycle protocol has limited statistical impact on selected biomechanical responses, while physiological and perceptual responses were altered, during a subsequent run, regardless of athlete type. That said, the ability of transition-trained athletes to transition comfortably between disciplines was highlighted, which may have important performance implications.

Sridhar, Naren. "Impact of product appearance and other influencing factors in the consumers' decision making : perceptual cycle model of urban young adults in India." Thesis, University of Huddersfield, 2018. http://eprints.hud.ac.uk/id/eprint/34769/.

Full text
Abstract:
Product appearance has been considered a significant factor of influence in the consumer behaviour, but its impact alongside other factors like cost, features and intrinsic psychological factors on the decision making has not been in focus. This is especially the case in the Indian urban context where both consumer behaviour and the influencing factors have not been adequately studied. Based on the mixed methods research philosophy, this study employed both quantitative and qualitative data collection methods, to empirically study the in-store consumer behaviour of the young urban Indian adults (18-25 years). The product category chosen for this study was both a functional and a fashion accessory: wristwatches. Literature related to the various areas of the cultural, sociological and economical conditions of the Indian consumer context were studied alongside theories of consumer behaviour based on cognitive psychology. Primary data was collected from a combination of 74 questionnaire survey responses, 101 observation episodes and 7 expert interviews. This large amount of data was analysed based on the paradigms of grounded theory coding levels as well as the theoretical foundation of the perceptual cycle model. The findings of the study presented an interesting and new perspective of the Indian consumer filling existing gaps in knowledge. The main finding related to product appearance vis-à-vis other competing factors as ‘stimuli’, was that it has very low influence on the in-store purchase behaviour of the Indian consumer, with limited impact on the final purchase decision, cost factor is the key influencing factor in this decision. However, the other key influencing factors in the ‘exploration’ and ‘schema’ were the socio-psychological factors of peer groups, family influence, conformity and symbolic interaction, each of which were examined independently and together in the perceptual cycle. The finding also augmented the pivotal role of peer and family influences on the decision making. Finally, a new conceptual framework, based on the perceptual cycle model and reasoned action model, in the form of an integrated decision model, amending the deficiencies in both, to include the key factors of emotions, attitudes, beliefs and behavioural intent was developed based on the findings of the study.

Abstract:
Analysons-nous le monde de façon continue ou bien selon une séquence d'évènements, un peu comme des instantanés pris par une caméra vidéo ? C'est la question qui a motivé ma thèse dans un premier temps. De précédentes expériences ont démontré que l'information visuelle était échantillonnée de façon périodique par l'attention, et que ce traitement était supporté par des oscillations de l'activité EEG. Dans le 1er papier, en utilisant la TMS, nous avons pu établir pour la première fois une relation causale entre la phase des oscillations spontanées, l'excitabilité cérébrale et la perception visuelle. Dans une autre série d'expériences, nous nous sommes demandé quel était le comportement spatio-temporel de l'attention au cours de tâches de recherche visuelle. A l'aide de diverses expériences (papiers 2 à 4) et de différentes techniques (TMS, EEG, psychophysique), nous avons pu établir des arguments convaincants en faveur d'un échantillonnage périodique de l'information visuelle par l'attention. De plus, dans le 5ème papier, nous avons pu clarifier une question hautement débattue concernant les tâches de recherche visuelle en éliminant la possibilité d'un traitement en parallèle de l'intégralité des stimuli présents à l'écran, suggérant un traitement séquentiel des différents stimuli au cours de la recherche. Ce travail de thèse a permis d'apporter des arguments forts en faveur d'un traitement périodique, voire séquentiel, de l'information visuelle par l'attention
Do we experience the world continuously or as a discrete sequence of events, like samples of a video camera? This is the first question motivating my PhD work. Previous experiments have shown that visual information may be sampled periodically by attention, this processing being supported by oscillations in the EEG brain activity. In paper 1, using TMS, we were able to establish for the first time a causal relation between the phase of ongoing oscillations, brain excitation and visual perception. In another series of experiments, we explored the spatio-temporal behaviour of attention during visual search tasks. Using various experiments (papers 2 to 4) and various techniques (TMS, EEG, psychophysics), we brought convincing and converging evidence in favour of a periodic sampling of visual information by attention. Moreover, in paper 5, we were able to clarify an age-old debate concerning visual search tasks by ruling out the possibility that attention is distributed in parallel over all stimuli in the search array, suggesting a sequential processing of the different stimuli during the search. Overall, this PhD work gives strong arguments in favour of a periodic, and perhaps sequential, processing of visual information by attention

Abstract:
This study explores the concept of feedback from various perspectives in psychology and cognitive science. Specifically, the theories of ecological psychology, situated and Distributed Cognition, Cognitive Systems Engineering and Embodied cognition are investigated and compared. Cognitive Systems Engineering provides a model of feedback and related constructs, to understand human behavior in complex working environments. Earlier theories such as ecological psychology, considered feedback as direct perception. Situated cognition clearly inherits ideas from ecological psychology, whereas distributed cognition provides a deeper understanding of feedback through artifact use. Cognitive Systems Engineering provides a systematic view of feedback and control. This framework is a suitable perspective to understanding feedback in human-machine settings.

Abstract:
Des travaux récents indiquent qu'il existe des différences fondamentales entre les systèmes visuel et auditif: tandis que le premier semble échantillonner le flux d'information en provenance de l'environnement, en passant d'un "instantané" à un autre (créant ainsi des cycles perceptifs), la plupart des expériences destinées à examiner ce phénomène de discrétisation dans le système auditif ont mené à des résultats mitigés. Dans cette thèse, au travers de deux expériences de psychophysique, nous montrons que le sous-échantillonnage de l'information à l'entrée des systèmes perceptifs est en effet plus destructif pour l'audition que pour la vision. Cependant, nous révélons que des cycles perceptifs dans le système auditif pourraient exister à un niveau élevé du traitement de l'information. En outre, nos résultats suggèrent que du fait des fluctuations rapides du flot des sons en provenance de l'environnement, le système auditif tend à avoir son activité alignée sur la structure rythmique de ce flux. En synchronisant la phase des oscillations neuronales, elles-mêmes correspondant à différents états d'excitabilité, le système auditif pourrait optimiser activement le moment d'arrivée de ses "instantanés" et ainsi favoriser le traitement des informations pertinentes par rapport aux événements de moindre importance. Non seulement nos résultats montrent que cet entrainement de la phase des oscillations neuronales a des conséquences importantes sur la façon dont sont perçus deux flux auditifs présentés simultanément ; mais de plus, ils démontrent que l'entraînement de phase par un flux langagier inclut des mécanismes de haut niveau. Dans ce but, nous avons créé des stimuli parole/bruit dans lesquels les fluctuations de l'amplitude et du contenu spectral de la parole ont été enlevés, tout en conservant l'information phonétique et l'intelligibilité. Leur utilisation nous a permis de démontrer, au travers de plusieurs expériences, que le système auditif se synchronise à ces stimuli. Plus précisément, la perception, estimée par la détection d'un clic intégré dans les stimuli parole/bruit, et les oscillations neuronales, mesurées par Electroencéphalographie chez l'humain et à l'aide d'enregistrements intracrâniens dans le cortex auditif chez le singe, suivent la rythmique "de haut niveau" liée à la parole. En résumé, les résultats présentés ici suggèrent que les oscillations neuronales sont un mécanisme important pour la discrétisation des informations en provenance de l'environnement en vue de leur traitement par le cerveau, non seulement dans la vision, mais aussi dans l'audition. Pourtant, il semble exister des différences fondamentales entre les deux systèmes: contrairement au système visuel, il est essentiel pour le système auditif de se synchroniser (par entraînement de phase) à son environnement, avec un échantillonnage du flux des informations vraisemblablement réalisé à un niveau hiérarchique élevé
Recent research indicates fundamental differences between the auditory and visual systems: Whereas the visual system seems to sample its environment, cycling between "snapshots" at discrete moments in time (creating perceptual cycles), most attempts at discovering discrete perception in the auditory system failed. Here, we show in two psychophysical experiments that subsampling the very input to the visual and auditory systems is indeed more disruptive for audition; however, the existence of perceptual cycles in the auditory system is possible if they operate on a relatively high level of auditory processing. Moreover, we suggest that the auditory system, due to the rapidly fluctuating nature of its input, might rely to a particularly strong degree on phase entrainment, the alignment between neural activity and the rhythmic structure of its input: By using the low and high excitability phases of neural oscillations, the auditory system might actively control the timing of its "snapshots" and thereby amplify relevant information whereas irrelevant events are suppressed. Not only do our results suggest that the oscillatory phase has important consequences on how simultaneous auditory inputs are perceived; additionally, we can show that phase entrainment to speech sound does entail an active high-level mechanism. We do so by using specifically constructed speech/noise sounds in which fluctuations in low-level features (amplitude and spectral content) of speech have been removed, but intelligibility and high-level features (including, but not restricted to phonetic information) have been conserved. We demonstrate, in several experiments, that the auditory system can entrain to these stimuli, as both perception (the detection of a click embedded in the speech/noise stimuli) and neural oscillations (measured with electroencephalography, EEG, and in intracranial recordings in primary auditory cortex of the monkey) follow the conserved "high-level" rhythm of speech. Taken together, the results presented here suggest that, not only in vision, but also in audition, neural oscillations are an important tool for the discretization and processing of the brain's input. However, there seem to be fundamental differences between the two systems: In contrast to the visual system, it is critical for the auditory system to adapt (via phase entrainment) to its environment, and input subsampling is done most likely on a hierarchically high level of stimulus processing

Abstract:
L'activité de notre cerveau est intrinsèquement rythmique : des oscillations sont observées à tous les niveaux de son organisation. Cette rythmicité de l'activité cérébrale influence notre perception. En effet, au lieu de superviser continuellement notre environnement, notre cerveau effectue de brèves " clichés " du monde extérieur (entre 5 et 15 par seconde). Cela crée des cycles perpétuels : notre perception visuelle fluctue en fonction de la phase de l'oscillation sous- jacente. De nombreuses données témoignent du fait que les oscillations cérébrales à différentes fréquences sont fondamentales à la formation de notre perception visuelle. Lors de cette thèse, nous avons utilisé le Paradigme de Bruit Blanc comme outil pour comprendre l'influence des oscillations sur la perception visuelle et qui par extension pourra être utilisé pour contrôler cette perception. Le paradigme de bruit blanc visuel utilise des séquences de flashs dont la luminance varie aléatoirement (créant ainsi du " bruit blanc "), comme stimuli, qui contraignent l'activité cérébrale de manière prédictible. Les réponses impulsionnelles à ces séquences de bruit blanc sont caractérisées par une composante oscillatoire forte dans la bande alpha (~10Hz), similaire à un écho perceptuel. Puisque les réponses impulsionnelles sont un modèle de la réponse de notre cerveau à un flash dans la séquence de bruit blanc, elles peuvent être utilisées pour reconstruire (plutôt qu'enregistrer) l'activité cérébrale en réponse à de nouvelles séquences de stimulation. Par ailleurs, des cibles ont été introduites au sein des séquences de bruit blanc à un niveau proche du seuil de perception, et le décours temporel de cette activité reconstruite autour de la présentation des cibles a été extrait. Ainsi, l'EEG reconstruit peut être utilisé pour étudier l'influence de ces oscillations contraintes sur la perception visuelle, indépendamment des autres types de signaux généralement enregistrés dans l'EEG. Dans un premier temps, nous avons validé le paradigme de bruit blanc en montrant que : 1) les séquences de bruits blancs influencent bien la détection des cibles, 2) les échos perceptuels évoqués par les séquences de bruit blancs sont stables dans le temps, 3) ces échos sont un bon modèle de l'activité cérébrale enregistrée par EEG, et 4) leurs bases neuronales se situent dans les aires visuelles primaires. Dans un second temps, nous avons étudié la relation entre ces oscillations cérébrales contrôlées par la séquence de bruit blanc et la détection des cibles. Ici, nous montrons que l'activité EEG reconstruite nous aide à déterminer la véritable latence à laquelle la phase de l'oscillation (thêta) influence la perception. De plus, nous avons aussi montré que l'amplitude de l'oscillation (alpha) influence la détection des cibles et ce, indépendamment des fluctuations des facteurs endogènes (tel que l'attention). Enfin, tirant parti de ce lien entre oscillation et perception, nous construisons deux algorithmes qui permettent de contrôler la perception des sujets. Tout d'abord, nous mettons au point un modèle " universel " de la perception qui permet de prédire, pour n'importe quel observateur, si une cible dans une séquence de bruit blanc sera vue ou non. Ensuite, nous construisons un modèle individuel qui utilise l'écho perceptuel de chaque sujet comme clé de cryptage et nous permet de présenter des cibles à des moments où la cible sera détectée par un sujet seulement au détriment de tous les autres sujets, créant ainsi une sorte de système de cryptage neuronal (" Neuro-Encryption ")
Our brain activity is inherently rhythmic: oscillations can be found at all levels of organization. This rhythmicity in brain activity gives a rhythm to what we see: instead of continuously monitoring the environment, our brains take "snapshots" of the external world from 5 to 15 times a second. This creates perceptual cycles: depending on the phase of the underlying oscillation, our perceptual abilities fluctuate. Accumulating evidence shows that brains oscillations at various frequencies are instrumental in shaping visual perception. At the heart of this thesis lies the White Noise Paradigm, which we designed as a tool to better understand the influence of oscillations on visual perception and which ultimately could be used to control visual perception. The White Noise Paradigm uses streams of flashes with random luminance (i.e. white noise) as stimuli, which have been shown to constrain brain oscillations in a predictable manner. The impulse response to WN sequences has a strong (subject specific) oscillatory component at ~10Hz akin to a perceptual echo. Since the impulse response is a model of how our brains respond to one single flash in the sequence, they can be used to reconstruct (rather than record) the brain activity to new stimulation sequences. We then present near-perceptual threshold targets embedded within the WN sequences and extract the time course of these predicted/reconstructed background oscillations around target presentation. Thus, the reconstructed EEG can be used to study the influence of the oscillatory components on visual perception, independently of other types of signals usually recorded in the EEG. First, we validate the White Noise Paradigm by showing that: 1) the WN sequences do modulate behaviour, 2) the perceptual echoes evoked by these WN sequences are stable in time, 3) they are a (relatively) good model of the subject's recorded brain activity and 4) their neuronal basis can be found in the early visual areas. Second, we investigate the relationship between these constrained brain oscillations and visual perception. Specifically, we show that the reconstructed EEG can help us recover the true latency at which (theta) phase influences perception. Moreover, it can help us uncover a causal influence of (alpha) power on target detection, independently from any fluctuation in endogenous factors. Finally, capitalizing on the link between oscillations and perception, we build two algorithms used to control the perception of subjects. First, we build a "universal" forward model which can predict for any observer whether a particular target will be seen or not. Second, we build a subject-dependent model which can predict whether a particular subject (for whom EEG was recorded previously) will perceive a given target or not. Critically, this can be used to present targets optimized to be perceived by one subject only, to the detriment of all other subjects, creating a sort of "Neuro-Encryption" system

Abstract:
This chapter begins to explain many of our most important perceptual and cognitive abilities, including how we rapidly learn to categorize and recognize so many objects and events in the world, how we remember and anticipate events that may occur in familiar situations, how we pay attention to events that particularly interest us, and how we become conscious of these events. These abilities enable us to engage in fantasy activities such as visual imagery, internalized speech, and planning. They support our ability to learn language quickly and to complete and consciously hear speech sounds in noise. The chapter begins to explain key differences between perception and recognition, and introduces Adaptive Resonance Theory, or ART, which is now the most advanced cognitive and neural theory of how our brains learn to attend, recognize, and predict objects and events in a changing world. ART cycles of resonance and reset solve the stability-plasticity dilemma so that we can learn quickly without new learning forcing catastrophic forgetting of previously learned memories. ART can learn quickly or slowly, with supervision and without it, and both many-to-one maps and one-to-many maps. It uses learned top-down expectations, attentional focusing, and mismatch-mediated hypothesis testing to do so, and is thus a self-organizing production system. ART can be derived from a simple thought experiment, and explains and predicts many psychological and neurobiological data about normal behavior. When these processes break down in specific ways, they cause symptoms of mental disorders such as schizophrenia, autism, amnesia, and Alzheimer’s disease.

Abstract:
The term Product realization is usually used to describe the physical realization of a product in the product development cycle. Therefore, the term may or may not include conceptualization and design phases. Considering that product realization means bringing a product to reality, it is important to study the concept of reality to understand the role of conceptualization, design, and manufacturing in product realization. In this paper, the concept of reality is expanded to include the perceptual and virtual realities as integral parts of the product realization process. This paper discusses the three phases of realization and their interactions. It also addresses the key roles of conceptualization, design and manufacturability in the realization process. To illustrate the concepts, presented in the paper, some examples are included.

Abstract:
The focus of this paper is case and real-life problem-based (Ewell, 1997) experiential learning with computer information system projects at California State University Stanislaus. The experiential learning occurs within a four- stage cycle: concrete experience, reflective observation, abstract conceptualization, and active experime n-tation. The four principles and strategies applied to bring knowing and doing together are: concreteness, involvement, dissonance, and reflection. The paper shows how the four types of learning environments (affective, perceptually oriented, symbolic, behavioral) are implemented, and student teams guided. Multi-disciplinary aspects of experiential education, and drawbacks specific to the academic environment in assessing students’ performance in team projects are discussed.
