In the first section a sketch of a tense logic is presented and a mechanism is suggested for including aspects of the tense logic into the Grammar (theory of language). Specifically, several grammatical structures are shown to incorporate temporal features. A semantic projection mechanism is utilized to amalgamate the temporal features in elements…

The aim of the study was to investigate the developmental trajectory of error monitoring. For this purpose, children (age 7-8), young adolescents (age 13-14) and adults (age 23-24) performed a Go/No-Go task and were compared on overt reaction time (RT) performance and on event-related potentials (ERPs), thought to reflect error detection…

The Zahlen-Verbindungs-Test (ZVT) represents a highly feasible measure of information-processing speed that correlates quite highly with standard psychometric tests of intelligence. The present study was designed to identify specific stages of the sensorimotor processing system that may account for individual differences in overall variability of…

The present study was designed to evaluate the effect of HIV/AIDS on cognitive control and to determine if the effect is modified by familial risk for either alcohol or mood disorders. Sixty HIV-1 seropositive and 75 seronegative volunteers were assigned to four subgroups defined by the crossing of a diagnosis of alcohol dependence in the…

This study attempted to evaluate the efficacy of time delay in increasing the academic response accuracy of moderately retarded adolescents. The time delay technique provided a means by which "cognitive organizers" could be taught to the students to mediate their behavior and improve academic performance. A modified multiple baseline…

The role of autonomic arousal in feeling states has long been of interest to psychologists. To examine the necessity of arousal for an effective mood induction, 60 college students were instructed either to exercise vigorously (high arousal group), exercise lightly with a rest period (low arousal group), or complete a questionnaire (no arousal…

Two studies were done to investigate the effects of personality, as dichotomized along a thought-action dimension, on time perception. Results of both were similar. The high-extraversive subjects underestimated and the high-introversive subjects overestimated time. (Author)

In this study, which examines the relationship between level of information processing and level of general socialization, a total of 90 children aged 11 and 14 years and a group of 17 adults were presented with an organizational problem: how to order simultaneously presented tasks. Subjects were individually shown a map with locations and…

Three pairs of spatial antonyms (higher than/lower than, above/below, and rising away from/falling away from) were used in a task in which subjects judged whether a sentence accurately described a previously presented pictorial relationship. Subjects' reaction times were used as the dependent measure. Since all three word pairs were used…

Encoding and retrieval of temporal and spatial order information was investigated in the free recall and probed recognition performance of 3-, 4-, 5-. and 6-year-old children. (SB)

Examines development of processing speed in three backward masking studies, where presentation of second stimulus figure (mask) within a critical time interval from arrival of first figure (target) interrupts processing of first. Results indicate that processing time increases until early adolescence; changes are less marked after 13 years of age.…

This study is consistent with a model of semantic memory that assumes that the memory store is organized primarily into noun categories, and that the process of retrieving information from this store consists of entering the appropriate category as a first step. (Authors)
