The phenomenon of insight is frequently characterized by the experience of a sudden and certain solution. Anecdotal accounts suggest that insight frequently occurs after the problem solver has taken some time away from the problem (i.e., incubation). However, the mechanism by which incubation may facilitate insight problem-solving remains unclear.…

This study tested two cognitive models, learning styles and dual coding, which make contradictory predictions about how learners process and retain visual and auditory information. Learning styles-based instructional practices are common in educational environments despite a questionable research base, while the use of dual coding is less…

Introduction: This study explored the variables of executive functioning (EF) that permitted the evaluation of EF both at home and at school. The objective was to compare the results of the evaluations of these functions in children aged 5 to 6 years, and see to what extent these variables predicted mathematics performance best. Method: Sixty-six…

Overgeneral memory (OGM) refers to difficulty in retrieving specific autobiographical memories. The tendency to be overgeneral in autobiographical memory recall is more commonly observed among individuals with emotional disorders compared with those without. Despite significant advances in theory and identification of mechanisms that underlie the…

Children growing up in poverty have a higher likelihood of exposure to multiple forms of adversity that jeopardize their chances of academic success. The current paper identifies school mobility, or changing schools, as 1 such poverty-related risk. Using a sample of low-income, predominantly ethnic-minority children (n = 381) in Chicago, this…

An experiment compared the impact of more and less semantically connected sentence contexts on vocabulary learning. Third graders (N = 40) were taught the definitions and meanings of six unfamiliar verbs: "anticipate," "attain," "devise," "restrain," "wield," and "persist." The verbs were…

Latent difference score models (e.g., McArdle & Hamagami, 2001) are extended to include effects from prior changes to subsequent changes. This extension of latent difference scores allows for testing hypotheses where recent changes, as opposed to recent levels, are a primary predictor of subsequent changes. These models are applied to…

This response to Brainerd and Reyna's paper (in this issue) argues that the common resources hypothesis can be applied to a wider range of phenomena than can the output-interference hypothesis. Presents results of a dual-task experiment under bidirectional deficits. Concludes that dual-task studies do not provide critical tests of the resources…

This study examined the correlates of symptom-seeking behavior for Alzheimer's disease (AD) among middle-aged persons. Symptom seeking, the tendency to search for signs of disease, is one manifestation of an individual's concern about developing AD. The data were obtained from a survey of two subsamples of 40-60 year old adults: 1) 108 adult…

A proposal to formulate nomothetic theories -- general statements or scientific laws -- in a way to allow for an immediate test of individual differences is presented. The need for such a proposal is cited in recent developments in structural model building in the area of memory called information processing and in the concern to bring individual…

Meta-analysis of 225 hypothesis tests of measures of memory for order (MFO) and the relationship of MFO and measures of general ability demonstrate a significant relationship between MFO and standardized test scores. Fifty-one independent samples were tested. MFO task quality was a significant predictor of effect size. (SLD)
