Satiation Effect

This study deals with generalization of the semantic satiation effect to a concept formation task which involves the grouping of words into classes. Experimental Ss were given satiation treatment on words which were thought to mediate solution to the classification task, while control Ss were given satiation treatment on irrelevant words. It was shown that experimental Ss differed from controls with respect to the type of solutions given in the concept formation task.

Schizophrenic Patients

The aim of the research was to explain the cognitive mechanisms responsible for formal language disorders in schizophrenia by relating them to the semantic satiation effect.The semantic satiation is the subjective and temporary experience of loss of meaning of words which are repeatedly and rapidly pronounced. Saying it aloud or fixating it the person ceases to understand the word's meaning still being able to recognizing its formal features. The loss of access to the meaning of words and building the utterances on the basis of formal aspects of words is a common feature of schizophrenic language. Therefore it could be assumed that schizophrenic patients would be prone to satiation effect more than healthy subjects.Semantic satiation was determined for patients suffering from schizophrenia and for healthy controls. Participants task was to compare the meanings of two words presented on a computer screen and decide if they are semantically related. Negative, positive and emotionally neutral words were used as the first element for each pair and they were satiated by the prolonged presentation. It was expected that the loss of meaning of satiated word would delay participants’ lexical decision and that this effect should be stronger for the schizophrenic than for control group.The results confirmed that people suffering from schizophrenia are more susceptible for semantic satiation effect. Also it was observed that in this group the satiation effect depends on valence of words. Emotionally positive and negative words were satiated faster than neutral ones.

Skipping Breakfast

Abstract. It has been generally accepted that skipping breakfast adversely affects cognition, mainly disturbing the attentional processes. However, the effects of short-term fasting upon brain functioning are still unclear. We aimed to evaluate the effect of skipping breakfast on cognitive processing by studying the electrical brain activity of young healthy individuals while performing several working memory tasks. Accordingly, the behavioral results and event-related brain potentials (ERPs) of 20 healthy university students (10 males) were obtained and compared through analysis of variances (ANOVAs), during the performance of three n-back working memory (WM) tasks in two morning sessions on both normal (after breakfast) and 12-hour fasting conditions. Significantly fewer correct responses were achieved during fasting, mainly affecting the higher WM load task. In addition, there were prolonged reaction times with increased task difficulty, regardless of breakfast intake. ERP showed a significant voltage decrement for N200 and P300 during fasting, while the amplitude of P200 notably increased. The results suggest skipping breakfast disturbs earlier cognitive processing steps, particularly attention allocation, early decoding in working memory, and stimulus evaluation, and this effect increases with task difficulty.

Processing Mechanisms

Abstract Most cognitive psychophysiological studies assume (1) that there is a chain of (partially overlapping) cognitive processes (processing stages, mechanisms, operators) leading from stimulus to response, and (2) that components of event-related brain potentials (ERPs) may be regarded as manifestations of these processing stages. What is usually discussed is which particular processing mechanisms are related to some particular component, but not whether such a relationship exists at all. Alternatively, from the point of view of noncognitive (e. g., “naturalistic”) theories of perception ERP components might be conceived of as correlates of extraction of the information from the experimental environment. In a series of experiments, the author attempted to separate these two accounts, i. e., internal variables like mental operations or cognitive parameters versus external variables like information content of stimulation. Whenever this separation could be performed, the latter factor proved to significantly affect ERP amplitudes, whereas the former did not. These data indicate that ERPs cannot be unequivocally linked to processing mechanisms postulated by cognitive models of perception. Therefore, they cannot be regarded as support for these models.
