Response latencies in naming visually displayed numbers were measured for 20 Ss under control and alcohol treatments. The size of the stimulus pool was varied by sets of trials to produce stimulus-response uncertainty in the range 0 to 5 bits. Response latencies were a function of the amount of uncertainty, but alcohol impairment was not.

Older Populations

Psychometrics permits the quantification of cognition, affect and behaviour, thus permitting both the identification of pathology and degree of deviation from normality. These methods have been principally used in older populations to screen affective and cognitive disorders, as an adjunct to the differential diagnosis of different forms of cognitive dysfunction and also to describe and monitor the functional consequences of pathology. The application of psychometric tests in older populations raises several problems, notably the confounding effects of associated pathologies, changing definitions of disease threshold in parallel with advances in medical technology, and inadequate knowledge of normal information processing at higher ages. Computerized assessment, once considered inappropriate in older populations, is now commonly used to standardize administration procedures and tailor testing to individual competency. It has also permitted the more accurate measurement of information processing time, which is important in the diagnosis of many neuropsychiatric disorders.

The influence of target-word affective properties on information processing time in a high speed visual-search task was studied. The 24 words were embedded in random-letter matrices, with one word per matrix. Subjects (5 male, 5 female) were tested. Words extreme on emotionality (positive vs negative affect) yielded significantly longer latencies than neutral words. The results were discussed in the light of related list-learning and problem-solving research.

Abstract. Four experiments were conducted to investigate contextual modulations of the Simon effect. The results showed that the Simon effect was quantitatively different depending on which kind of task needed to be performed. Importantly, this effect did not depend on the relative processing time of the relevant dimension, nor on a direct or indirect overlap between the relevant and irrelevant stimulus part. To account for the data, we refer to the neural overlap hypothesis, which extends the definition of dimensional overlap ( Kornblum, Hasbroucq, & Osman, 1990 ) with similarity of processing regions as the key factor for the interaction between relevant and irrelevant information processing.
