Abstract:
A fundamental property of visual attention is to select targets from interfering distractors. However, attention can also facilitate the detectability of near-threshold items presented in isolation. The extent to which these two perceptually challenging conditions are resolved by the same neural mechanisms is not well known. In the present event-related fMRI experiment, subjects performed a letter identification task under two perceptually challenging conditions; when the luminance contrast of a target letter was reduced (perceptual visibility manipulation) and when the target letter was flanked by distractors (perceptual interference manipulation). Perceptual interference recruited the right parietal and mid-lateral frontal cortex, while perceptual visibility activated these regions bilaterally. The overlap of activated areas between the two perceptual manipulations suggests that a single parieto-frontal network is summoned under both perceptual visibility and interference conditions.

Abstract:
This article discusses some of the results of an experiment in which native speakers of English, Dutch advanced and intermediate learners of English listened to frequently occurring English words, which had been sliced into fragments of increasing duration. From the initial 100 ms. of a word onwards, each fragment contained the preceding fragment and an added 50 ms. of the word. The subjects were asked to write down the sounds they had heard and to identify the test words as soon as they had sufficient perceptual information about the words. Their responses show that the Dutch intermediate learners needed significantly more perceptual information before they were able to recognize a word than the advanced learners and the native speakers.

Abstract:
Abstract Perceptual errors are common contributors to missed diagnoses in the clinical practice of radiology. While the physical attributes of an image such as image resolution, signal-to-noise characteristics, and anatomic complexity are major causes of poor conspicuity of pathologic lesions, there are major interrelated cognitive contributors to visual errors. The first is satisfaction of search (SOS), where the detection of an abnormality results in premature termination of further search. Another form of incomplete search pattern is visual isolation, where a radiologist’s search pattern is truncated to the main areas of an image, while little or no attention is given to peripheral areas. A second cognitive error is inattentional blindness, defined as the failure to notice a fully visible, but unexpected object because attention was otherwise engaged. Strategies for error mitigation have centered around the use of check lists, self prompting routines, and structured reporting within an institutional culture of safety and vigilance.

Abstract:
According to Gibson's direct theory, perception is an achievement, not a process. Perceptual error, therefore, is the failure to perceive. Taken in isolation, this assertion leads to implausible consequences, but taken together with other assertions of Gibson, it may be understood, without contradiction, to mean that there is no absolute error in perception. Whether perception is successful or not is determined by the context in which the perceptual act occurs.

Abstract:
Acoustic or perceptual cues used for speech perception can be very helpful in almost all areas of speech signal processing. A new methodology 3-Dimensional-Deep Search and a new visualized intelligible time-frequency computerbased model AI-gram have been developed and are being researched since the last several years (Human Speech Recognition (HSR) research group at the University of Illinois Urbana-Champaign) for isolation of stable perceptual cues of consonants. The perceptual cues of nasal consonants [1] have been successfully found considering these techniques [1]. The previous work is extended by assessing the changes in nasal sound perception and cue region is modified by using digital signal processing method. The amplitude of the perceptual cue region is amplified, attenuated or ignored completely and then the perception score is measured. A high correlation between the amplitude of the cue region and the perception score is found. The intelligibility of the entire token is increased or decreased approximately in a similar fashion as the cue region modified amplitude which is measured by the MMSE shift of the perceptual score curve. This validates that the regions identified are perceptual cue regions for nasal consonants. The digital signal processing method proposed can be used as a new approach for enhancing speech signal in noisy conditions.

Abstract:
This study is a review article. Gerontology literature was reviewed and issues of latent aging were systematically formed. According to the results of the study, latent aging consists of perceptual diagnosis, research, adoption, and reactive actions.Reactive actions include the social, psychological and physical effects of latent aging. The social effects of latent aging are the decline of social relations and social isolation. Depression, stress, anxiety, traumas and cognitive decline are among the psychological effects. Chronic musculoskeletal pain, sleep disorders, premature mortality, and suicidal ideation were determined as physical effects. The detection of latent aging is important in the prevention of chronic diseases.It was revealed that latent aging has the following four main processes: perceptual diagnosis and coding, research and comparison, adoption and reactive actions. Furthermore, this aging approach has three significant effects: social, psychological and physical.

Abstract:
Five experiments investigated listeners' capacities for perceiving polytonality, in which materials from more than one key are employed simultaneously. The stimulus materials were based on a particularly striking example of polytonal writing from Stravinsky's Petroushka; it outlines in arpeggiated form the tonic triads of two maximally distant major keys, C and F# major. The first experiment demonstrates, using the probe-tone technique, that the two component voices presented in isolation establish the expected keys and that when they are combined some influence of both keys is felt. The second and third experiments indicate, however, that when presented dichotically the two components cannot be separated perceptually; this is attributed to the two voices having the same rhythmic and contour patterns and being sounded in the same pitch range. The fourth experiment replicated the findings of the first three, using listeners very familiar with the particular passage. The final experiment tested an alternative theoretical account, the octatonic collection. Probe-tone ratings following an octatonic scale did not account satisfactorily for the data for the musical passage, but the hierarchy of priorities proposed by Van den Toorn (1983) fit the data better than the major key profiles, especially for the experienced listeners.

Abstract:
This book argues that human perception and perceptual consciousness are richly multisensory. Its thesis is that the coordinated use of multiple senses enhances and extends human perceptual capacities and consciousness in three critical ways. First, crossmodal perceptual illusions reveal hidden multisensory interactions that typically make the senses more coherent and reliable sources of evidence about the environment. Second, the joint use of multiple senses discloses more of the world, including novel features and qualities, making possible new forms of perceptual experience. Third, through crossmodal dependence, plasticity, and perceptual learning, each sense is reshaped by the influence of others, at a time and over time. The implication is that no sense—not even vision itself—can be understood entirely in isolation from the others. This undermines the prevailing approach to perception, which proceeds sense by sense, and sets the stage for a revisionist multisensory approach that illuminates the nature, scope, and character of sense perception.

Abstract:
A rising vision for AI in the open world centers on the development of systems that can complement humans for perceptual, diagnostic, and reasoning tasks. To date, systems aimed at complementing the skills of people have employed models trained to be as accurate as possible in isolation. We demonstrate how an end-to-end learning strategy can be harnessed to optimize the combined performance of human-machine teams by considering the distinct abilities of people and machines. The goal is to focus machine learning on problem instances that are difficult for humans, while recognizing instances that are difficult for the machine and seeking human input on them. We demonstrate in two real-world domains (scientific discovery and medical diagnosis) that human-machine teams built via these methods outperform the individual performance of machines and people. We then analyze conditions under which this complementarity is strongest, and which training methods amplify it. Taken together, our work provides the first systematic investigation of how machine learning systems can be trained to complement human reasoning.
