Drawing a picture of the referent of a word produces considerably better recall and recognition of that word than does a baseline condition, such as repeatedly writing the word, a phenomenon referred to as the drawing effect. Although the drawing effect has been the focus of much recent research, it is not yet clear what underlies the beneficial…

Creative thinking shares many characteristics with traditional complex tasks. We investigated whether implicit theories of creativity would affect creative thinking in a way similar to the impact of implicit theories of intelligence on academic tasks. We altered participants' theories of creativity to be either more incremental or more…

Purpose: The purpose of this study was to examine the verbal short-term memory skills of children who stutter (CWS) and children who do not stutter (CWNS) in 2 experiments, focusing on the influence of phonological and semantic similarity. Method: Participants were 42 CWS and 42 CWNS between the ages of 3;0 and 5;11 (years;months). In Experiment…

Purpose: The study aims to test whether children with specific language impairment (SLI) show weaknesses in word retrieval and cognitive control and to find out whether impairments in the 2 domains are associated. Method: Thirty-one children with SLI (age: M = 8;11 years;months, SD = 1;1) and 31 age- and IQ-matched typically developing children…

A set of four experiments assessed the effects of establishing a comprehension-test expectancy (in contrast to a memory-test expectancy) on relative metacomprehension accuracy. Typically readers show poor relative metacomprehension accuracy while learning from text (i.e., they are unable to discriminate topics they have understood well from topics…

A striking characteristic of human thought is that we form representations about abstract kinds (Giraffes have purple tongues), despite experiencing only particular individuals (This giraffe has a purple tongue). These generic generalizations have been hypothesized to be a cognitive default, that is, more basic and automatic than other forms of…

A well-known hypothesis in education and amongst the general public is that matching instructional method with an individual's modality-specific learning style improves learning and cognitive performance. Several critical reviews in the past decade, however, have shown that the hypothesis has not been properly evaluated with appropriate…

This document traverses through a series of genealogical stories that span close to a century to provide context to higher learning, education, and development. The stories of elders help us re-member their dreams, re-frame the process for growth, and re-imagine the possibilities for development at the self, organizational, and community levels.…

Previous studies indicate that autobiographical memory is impaired in individuals with autism spectrum disorder (ASD). Successful recollection of information referring to one's own person requires the intact ability to re-activate representation of the past self. In the current fMRI study we investigated process of conscious reflection on the…

Three experiments investigated the relationship between future thinking and false memories. In Experiment 1, participants remembered familiar events (e.g., a holiday) from their past, imagined planning the same events in the future, or took part in a control condition in which they visualized typical events. They then rated a series of…

Memory for numbers improves with age. One source of this improvement may be learning linear spatial-numeric associations, but previous evidence for this hypothesis likely confounded memory span with quality of numerical magnitude representations and failed to distinguish spatial-numeric mappings from other numeric abilities, such as counting or…

For this dissertation, I tested whether transformative reminiscence training is a viable alternative to facilitated life reviews for older adults. Facilitated life reviews involve structured reminiscence, which is designed to enhance the self-positive reminiscence functions of identity consolidation, problem solving, and meaning-making death…

A set of four experiments assessed the effects of establishing a comprehension-test expectancy (in contrast to a memory-test expectancy) on relative metacomprehension accuracy. Typically readers show poor relative metacomprehension accuracy while learning from text (i.e., they are unable to discriminate topics they have understood well from topics…

Many individuals with autism spectrum disorder (ASD) can effectively decode and read words fluently, but have significantly below-average understanding of text. Following written directions may hold unique potential as it requires a reader to convert a written text into a goal-directed and observable performance. The present data-based case study…

Working memory performance in individuals with autism is a matter of debate in the literature. The purpose of this study was to evaluate the role of stimuli in the working memory of children with and without autism spectrum disorders (ASD). Sixteen children with ASD, clinically diagnosed as high functioning, were matched for gender and age and…
