Abstract:
The goal of the present study was to examine whether a backward masking paradigm, in which a prime and a mask stimuli were consecutively presented with a short stimulus onset asynchrony affected the time needed for either the perceptual or motor stages of processing and the simple reaction times. The times needed for the perceptual and motor stages were evaluated by measuring the stimulus-locked and response-locked lateralized readiness potentials. The results showed that the onset of the stimulus-locked lateralized readiness potentials under the backward masking paradigm took place earlier than it did under the condition of a mask stimulus presented alone, whereas the onset of the response-locked lateralized readiness potentials did not significantly differ under different stimulus conditions. These results suggested that the participants responded to the masked prime stimulus despite being unaware of the prime stimulus. This may have been mediated by facilitation of the perceptual rather than motor stages.

Abstract:
AbstractSmoking/nicotine improves cognitive performance for a variety of tasks. In most cases, reaction time (RT) is generally shorter after smoking/nicotine. While there may be some slight facilitation of stimulus-evaluation processing, most of the RT effects of nicotine appear to take place following the response-selection stage. This study investigated possible effects (in smokers) of smoking/nicotine on response preparation and execution processes using the lateralized readiness potential (LRP). On each trial, a warning stimulus preceded an imperative stimulus by 1.2s. The warning stimulus completely specified the correct response to the imperative stimulus. The study was completed in two morning sessions in which 4 cigarettes were smoked in each session. The nicotine yield of the cigarettes varied between sessions (0.05mg or 1.1mg). Maximum amplitudes of both the stimulus and response-locked LRPs were larger in the 1.1 mg session. For both stimulus- and response-locked LRPs, smoking the 1.1 mg cigarette (but not the 0.05 mg cigarette) shortened onset latency. However, the magnitude of the effect was much larger for the stimulus-locked LRPs, suggesting that response preparation is facilitated by smoking/nicotine to a greater degree than response execution.

Abstract:
Emotiv EPOC is a low-cost consumer headset capable of acquiring a raw EEG signal. The thesis evaluates its usage for an acquisition of research event-related potentials. A controlled laboratory experiment was performed with an objective of isolating the Bereitschaftspotential (Readiness Potential) and other movement-related potentials and comparing the results with the results of the previous research. The possibility of measuring the potential with Emotiv EPOC was not confirmed, most probably due to procedural issues during the experiment, however, further analysis of the data suggests its presence. Other outcomes of the research include qualitative findings about the headset, mainly its hardware construction, and testing feedback of EEGLab, an open source toolbox for EEG processing and visualization.

Abstract:
Die Studie hat zum Ziel, im Rahmen des Äußerungsproduktionsmodells die Annahme thinking for speaking (Slobin, 1996) experimentell zu überprüfen. Ansatzpunkt ist der Unterschied in der Stellung der Markierung einer Entscheidungsfrage zwischen drei Sprachen. Während der Fragemodus im Deutschen/Polnischen vor dem Frageinhalt markiert wird, geschieht die Modusmarkierung im Chinesischen nach dem Inhalt. Um die entsprechende Satzstruktur aufzubauen, sollte der Fragemodus beim syntaktischen Kodierungsprozess (speaking) im Deutschen/Polnischen vor, im Chinesischen nach dem Inhalt verarbeitet werden. Unter Zugrundelegung der inkrementellen Äußerungsproduktion gehen wir davon aus, dass die Verarbeitungsreihenfolge beim vorangehenden Konzeptualisierungsprozess (thinking) mit der syntaktischen Kodierungsabfolge übereinstimmt: Der Fragemodus wird im Deutschen/ Polnischen vor, im Chinesischen hingegen nach dem Inhalt konzeptualisiert. Um den zeitlichen Ablauf der zwei Konzeptualisierungsprozess zu ermitteln, bedienten wir uns des lateralisierten Bereitschaftspotenzials (lateralized readiness potential, LRP) im binären Wahlreaktions-Go/Nogo-Paradigma. Im Versuch reagierten deutsche, chinesische und polnische Muttersprachler auf dargebotene Bilder mit Tastendrücken und Sprechen. Zu beobachten war das Auftreten eines LRP bei Nogo, das signalisierte, in welcher Reihenfolge sich die Handwahl und die Nogo-Entscheidung realisierten Ein Nogo-LRP trat bei allen drei Sprechergruppen auf. Zudem wurde festgestellt, dass die Nogo-Entscheidung, die erwartungsgemäß mit der sprachlichen Verarbeitung des Fragemodus verbunden wurde, bei den drei Sprechergruppen ungefähr zeitgleich getroffen wurde. Die Befunde legen nahe, dass der Fragemodus in den drei Sprachen zeitlich nicht unterschiedlich, sondern einheitlich geplant wurde. Die Schlussfolgerung wird im Rahmen von thinking for speaking sowie dem Äußerungsproduktionsmodell diskutiert.
Languages differ in the marking of the sentence mood of a polar interrogative (yes/no question). For instance, the interrogative mood is marked at the beginning of the surface structure in Polish, whereas the marker appears at the end in Chinese. In order to generate the corresponding sentence frame, the syntactic specification of the interrogative mood is early in Polish and late in Chinese. In this respect, German belongs to an interesting intermediate class. The yes/no-question is expressed by a shift of the finite verb from its final position in the underlying structure into the utterance initial position, a move affecting, hence, both the sentence final and the sentence initial constituents. The present study aimed to investigate whether during generation of the semantic structure of a polar interrogative, i.e. the processing preceding the grammatical formulation, the interrogative mood is encoded according to its position in the syntactic structure at distinctive time points in Chinese, German, and Polish. In a two-choice go/nogo experimental design, native speakers of the three languages responded to pictures by pressing buttons and producing utterances in their native language while their brain potentials were recorded. The emergence and latency of lateralized readiness potentials (LRP) in nogo conditions, in which speakers asked a yes/no question, should indicate the time point of processing the interrogative mood. The results revealed that Chinese, German, and Polish native speakers did not differ from each other in the electrophysiological indicator. The findings suggest that the semantic encoding of the interrogative mood is temporally consistent across languages despite its disparate syntactic specification. The consistent encoding may be ascribed to economic processing of interrogative moods at various sentential positions of the syntactic structures in languages or, more generally, to the overarching status of sentence mood in the semantic structure.

Abstract:
A wide literature of predominantly behavioural experiments that use Stimulus Response Compatibility (SRC) have suggested that visual action information such as object affordance yields rapid and concurrent activation of visual and motor brain areas, but has rarely provided direct evidence for this proposition. This thesis examines some of the key claims from the affordance literature by applying electrophysiological measures to well established SRC procedures to determine the verities of the behavioural claims of rapid and automatic visuomotor activation evoked by viewing affording objects. The temporal sensitivity offered by the Lateralised Readiness Potential and by visual evoked potentials P1 and N1 made ideal candidates to assess the behavioural claims of rapid visuomotor activation by seen objects by examining the timecourse of neural activation elicited by viewing affording objects under various conditions. The experimental work in this thesis broadly confirms the claims of the behavioural literature however it also found a series of novel results that are not predicted by the behavioural literature due to limitations in reaction time measures. For example, while different classes of affordance have been shown to exert the same behavioural facilitation, electrophysiological measures reveal very different patterns of cortical activation for grip-type and lateralised affordances. These novel findings question the applicability of the label ‘visuomotor’ to grip-type affordance processing and suggest considerable revision to models of affordance. This thesis also offers a series of novel and surprising insights into the ability to dissociate afforded motor activity from behavioural output, into the relationship between affordance and early visual evoked potentials, and into affordance in the absence of the intention to act. Overall, this thesis provides detailed suggestions for considerable changes to current models of the neural activity underpinning object affordance.

Abstract:
Les troubles des tics, comme le syndrome de Gilles de la Tourette et le trouble de tics chroniques, sont des conditions neuropsychiatriques impliquant des tics moteurs et/ou phoniques. En plus de nombreuses comorbidités, les patients qui en sont atteints ont aussi des difficultés neuropsychologiques, notamment au niveau de l’inhibition et des fonctions motrices. La thérapie cognitivo-comportementale permet d’améliorer les tics et la condition générale de ces patients. Nous avons donc enregistré, durant une tâche de compatibilité stimulus-réponse, les potentiels évoqués cognitifs et les potentiels de latéralisation motrice (lateralized readiness potential; LRP) chez 20 patients atteints de trouble des tic avant et après une thérapie cognitivo-comportementale, et chez 20 participants contrôles. Chez les patients atteints de trouble des tics, nos résultats ont révélé une apparition plus tardive de l’amorce du LRP moyenné par rapport au stimulus, une amplitude plus élevée du LRP moyenné par rapport à la réponse, et une suractivation frontale liée aux processus d’inhibition. Suite à la thérapie, le retard au niveau de la latence de l’amorce du LRP moyenné par rapport à la réponse est comblé et l’amplitude du LRP moyenné par rapport à la réponse est normalisée, mais pas la suractivation frontale liée à l’inhibition. Cela suggère donc que la thérapie induit une modification des processus prémoteurs de sélection et de préparation de la réponse, ainsi que des processus d’exécution motrice, mais n’altère pas la suractivation frontale reliée aux fonctions inhibitrices. Étant donnés ces résultats, nous suggérons que la thérapie cognitivo-comportementale induit une modification du fonctionnement des aires motrices du cerveau.
Gilles de la Tourette syndrome and chronic tic disorder are two neuropsychiatric condition involving motor and/or phonic tics. In the DSM, these two conditions are characterized as “tic disorders”. Patients with such diagnoses face numerous comorbidities, and also show multiple neuropsychological impairments, especially concerning inhibition and motor processing. Tic symptoms, as well as general condition, can be improved with a cognitive-behavioural therapy (CBT). To this end, we recorded, during a stimulus-response compatibility task, event-related potentials and lateralized readiness potentials in 20 patients with tic disorder and 20 healthy controls. Patients and controls were paired on age, sex and hand dominance. Our result revealed a delay in stimulus-locked lateralized readiness potential (LRP) onset latency, higher response-locked LRP peak amplitude and a frontal overactivation related to stimulus inhibition in GTS and CTD patients. Following CBT, stimulus-locked LRP onset latency and response-locked LRP peak amplitude were normalized, but the frontal overactivation related to inhibition processing remained unchanged. These results suggest that CBT induces a modification of pre-motor processes such as response selection and preparation, as well as motor processes like response execution, but does not affect cortical activation related to stimulus inhibition. Since we found a reduction in tic symptoms, as well as a normalization of stimulus-locked LRP onset latency and response-locked LRP peak amplitude, and because LRPs are partly generated by the supplementary motor area, we suggest that CBT leads to a modification of this structure’s functioning.
