We previously showed that prenatal choline supplementation could increase the precision of timing and temporal memory and facilitate simultaneous temporal processing in mature and aged rats. In the present study, we investigated the ability of adult rats to selectively control the reinforcement-induced resetting of an internal clock as a function…

Purpose: The purpose of this study was to explore the usefulness of a simplified version of cognitive response analysis (CRA) as a formative evaluation tool for health education materials developed for small, unfunded projects. Design/methodology/approach: A group of women (n=15), aged between 25 and 50 years, provided cognitive responses (CRs)…

Seven-year-olds completed a Posner cued attention task, under both neutral and affectively charged conditions. Compared to the traditional (affect-neutral) Posner task, performance in the affective Posner task was marked by dramatic decreases in reaction times (RTs), an increase in errors, an increased validity effect (difference in RTs to the…

The purpose of this study was to compare listener processing demands when decoding alaryngeal compared to laryngeal speech. Fifty-six listeners were presented with single words produced by 1 proficient speaker from 5 different modes of speech: normal, tracheosophageal (TE), esophageal (ES), electrolaryngeal (EL), and synthetic speech (SS).…

These proceedings contain the papers of the International Conference on Mobile Learning 2013, which was organised by the International Association for Development of the Information Society, in Lisbon, Portugal, March 14-16, 2013. The Mobile Learning 2013 International Conference seeks to provide a forum for the presentation and discussion of…

Race and socioeconomic status (SES) moderated the link between children's sleep and cognitive functioning. One hundred and sixty-six 8- to 9-year-old African and European American children varying in SES participated. Sleep measures were actigraphy, sleep diaries, and self-report; cognitive measures were from the Woodcock-Johnson III and reaction…

This study investigated how people reason about simple mechanical devices and physical systems, and how reasoning methods and understanding of a device evolve over a period of exposure. Twelve students attending the Teachers College at Columbia University (New York) participated in the first of two experiments; and 10 students attending the same…

The processing of mental structures in perception appears to be serial, in that viewers can fill in missing parts from an impoverished stimulus following a top down process. To investigate the effects of unfamiliarity, complexity, and legibility on object and layout perception of unfamiliar stimuli, ten subjects were shown one of four ribbon…

The traditional explanation for dual-task interference is that tasks compete for scarce processing resources. Another possible explanation is that the outcome of the processing required for one task conflicts with the processing required for the other task. To explore the contribution of outcome conflict to task interference, this paper describes…

The widespread incidence of depression has promoted many theories about what variables are involved in this disorder. Beck has theorized that a depressive's negative affect results from a schema of negative views toward oneself. Gotlib and McCann have concluded that depressives have greater accessibility than nondepressives to negative content…

Sequential relationships between Stroop color-word stimuli were explored in a random discrete-trials manual response design. Posttrial availability of an interfering response was indicated by a subsequent reduction of reaction time when that response became appropriate. Previous evidence for suppression of competing responses is probably…

Investigates extent to which perceptual factors of speed and flexibility of closure represent more general processes also operating in cognitive and personality domains by including in a single factor analysis perceptual tests and new tests requiring cognitive abilities resembling closure abilities operating in the perceptual domain.

This examination of retrieval interference in memory theories argues that relevant world knowledge can reduce interference by integrating factors learned about a concept. Three recognition experiments were conducted and two hypotheses were considered to account for the results: human associative memory and script analysis. (Author/RD)

In two experiments, subjects were interrupted while listening to a two-clause sentence just before the last word of either the initial clause or the final clause. The two experiments together suggest that interclause semantic relations affect the immediate processing of clauses. (Author/EJS)

Comprehensibility ratings and sentence-by-sentence reading times of three-sentence narratives (triples) were studied as a function of the coherence of a triple. In both experiments, reading times did not differ for first sentences, but were longer for third sentences of unrelated than for related triples. (Author/RM)
