Background: Recent studies have demonstrated that individuals with Down syndrome (DS) present both central and verbal working memory deficits compared with controls matched for mental age, whereas evidence on visuospatial working memory (VSWM) has remained ambiguous. The present paper uses a battery of VSWM tasks to test the hypothesis that…

Animated models explicating how a problem is solved and why a particular method is chosen are expected to be effective learning tools for novices, especially when abstract cognitive processes or concepts are involved. Cognitive load theory was used to investigate how learners could be stimulated to engage in genuine learning activities. It was…

It has been suggested that individuals with dyslexia show poorer performance on those aspects of arithmetic that involve the manipulation of verbal representations, such as the use of fact retrieval strategies. The present study examined this in 13 children with dyslexia who showed normal general mathematics achievement and 16 matched controls.…

Background: A key aspect of social perception is the interpretation of others' intentions. Children with intellectual disabilities (IDs) have difficulty interpreting benign intentions when a negative event occurs. From a cognitive processing perspective, interpreting benign intentions can be challenging because it requires integration of…

The aim of the present study was to examine executive dysfunctioning and decreased processing speed as potential mediators of age-related differences in episodic memory. We compared the performances of young and elderly adults in a free-recall task. Participants were also given tests to measure executive functions and perceptual processing speed…

Research Findings: The current study examined preschoolers' processing of false belief situations presented in published picture books. Children were read one story with a plot that revolved around a single false belief occurrence and one story with multiple false belief occurrences. Children's narrative retellings of the stories were utilized as…

Purpose: This study was designed to replicate and extend a previous study of inferencing in which some adults with right hemisphere damage (RHD) generated but did not maintain predictive inferences over time (M. Lehman-Blake & C. Tompkins, 2001). Two hypotheses were tested: (a) inferences were deactivated, and (b) selection of previously generated…

There has been a widely held belief that people with autism spectrum disorders lack empathy. This article examines the empathy imbalance hypothesis (EIH) of autism. According to this account, people with autism have a deficit of cognitive empathy but a surfeit of emotional empathy. The behavioral characteristics of autism might be generated by…

This study aimed to test the hypothesis that children with autism spectrum disorder (ASD) use their knowledge of complement syntax as a means of "hacking out" solutions to false belief tasks, despite lacking a representational theory of mind (ToM). Participants completed a "memory for complements" task, a measure of receptive vocabulary, and…

Event schemas (generalized knowledge of what happens at common real-life events, e.g., a birthday party) are an important cognitive tool for social understanding: They provide structure for social experiences while accounting for many variable aspects. Using an event narratives task, this study tested the hypotheses that theory of mind (ToM)…

We propose that experience of emotion is a mental phenomenon, which requires resources. This hypothesis implies that a concurrent cognitive load diminishes the intensity of feeling since the 2 activities are competing for the same resources. Two sets of experiments tested this hypothesis. The first line of experiments (Experiments 1-4) examined…

Modern cognitive neuroscientific theories and empirical evidence suggest that brain structures involved in movement may be related to action-related semantic knowledge. To test this hypothesis, we examined the naming of environmental sounds in patients with corticobasal degeneration (CBD) and progressive supranuclear palsy (PSP), two…

Retrieval monitoring enhances episodic memory accuracy. For instance, false recognition is reduced when participants base their decisions on more distinctive recollections, a retrieval monitoring process called the distinctiveness heuristic. The experiments reported here tested the hypothesis that autobiographical elaboration during study (i.e.,…

Three hypotheses of forgetting from immediate memory were tested: time-based decay, decreasing temporal distinctiveness, and interference. The hypotheses were represented by 3 models of serial recall: the primacy model, the SIMPLE (scale-independent memory, perception, and learning) model, and the SOB (serial order in a box) model, respectively.…

Comments on articles by Botvinick et al. and Jacob et al. M. M. Botvinick, T. S. Braver, D. M. Barch, C. S. Carter, and J. D. Cohen (2001) implemented their conflict-monitoring hypothesis of cognitive control in a series of computational models. The authors of the current article first demonstrate that M. M. Botvinick et al.'s (2001)…
