Separate experiments focusing on attention to multiple stimuli, psychological refractory period, and motor coordination demonstrated that emergent aspects of the whole situation must also be considered. Performance under divided attention reflected an interaction between resource limitation, single task processes, and emergent aspects of the whole…

Used Visual Expectation Paradigm to describe information processing changes and individual differences during first year of life. Found regular age changes in mean reaction time and variability but not in minimum reaction time, suggesting that growth rate of sensory-detection information is constant during first year but age changes occur in level…

Speculates on underlying processes for the reaction time variance and age differences in anticipation latency using the Visual Expectation Paradigm. Discusses the dichotomization of reactive and anticipatory behavior, limitations of longitudinal designs, drawbacks in using standard procedures and materials, and inferences that can be made…

In forming an integrated theory of reflectivity as it occurs in clinical supervision, five experts in practitioner development were interviewed about attributes of supervisee reflectivity. Respondents' statements from initial interviews were categorized and presented to respondents for additional discussion. Grounded theory analysis was used to…

Proposes a cognitive approach to modeling users' perceptions in situations in which information content, information sources, and users themselves are constantly moving in time and space. A temporal-spatial model is explained and empirical support is provided by the results of a study of weather information users from a variety of occupations.…

Choice reaction time and simple reaction time were measured for 147 young adults for whom significant positive correlation between nerve conduction velocity in a brain nerve pathway and nonverbal intelligence was previously found. Results suggest that two largely independent neurophysiological processes affect intelligence. Differences in choice…

A study examined the executive functioning, in particular the attentional set-shifting deficits in Australian individuals ages 6-20 with high-functioning autism (n=12) and Asperger's disorder (n=12). Results indicate that individuals with autism had a deficiency in shifting from local to global processing, however, this was not observed in…

Determined the effects of classroom music instruction featuring the keyboard on the spatial-temporal reasoning of 62 kindergartners assigned to keyboard or no music conditions. Found that the keyboard group scored significantly higher than the no music group on both spatial-temporal tasks after 4 months of lessons, a difference that was greater in…

Studied whether the language spoken affects the way subjects think about time in 3 experiments involving: (1) 26 English-speaking and 20 native Mandarin-speaking college students; (2) 25 bilingual students; and (3) 70 native English speakers. Results suggest that language is a powerful tool for shaping thought about abstract domains and habitual…

This study used neuroimaging and behavioral techniques to examine the claim that processing capacity limitations underlie specific language impairment (SLI). Functional magnetic resonance imaging (fMRI) was used to investigate verbal working memory in adolescents with SLI and normal language (NL) controls. The experimental task involved a modified…

The aim of this study was to investigate the relationship between students' learning approaches to study on part-time, distance-learning management courses, and transfer of their learning to the workplace. The relationship between these two variables has rarely been considered before, as they emanate from research areas that have remained…

This study examined spoken-word recognition in children with specific language impairment (SLI) and normally developing children matched separately for age and receptive language ability. Accuracy and reaction times on an auditory lexical decision task were compared. Children with SLI were less accurate than both control groups. Two subgroups of…

In 2 experiments, bimanual 1:1 rhythmic coordination was performed concurrently with encoding or retrieval of word lists. Effects of divided attention (DA) on coordination were indexed by changes in mean relative phase and recurrence measures of shared activity between the 2 limbs. Effects of DA on memory were indexed by deficits in recall…

Current theories of environmental cognition typically differentiate between an online, transient, and dynamic system of spatial representation and an offline and enduring system of memory representation. Here the authors present additional evidence for such 2-system theories in the context of the disorientation paradigm introduced by R. F. Wang…

Previous work by Grannis and Jackson suggested that teachers, learners, feedback sources, instructional sequencing, material format, or other variables may exercise control over the learning environment. It was suggested that the behavioral structure of a classroom can be described in terms of a knowledge dimension, a social dimension, and an…
