The predictive validity and utility of assessment procedures can be increased by adding predictors to the prediction supplied by general ability tests. Of Jensen's early work comes the suggestion of focusing on the cognitive ability short-term memory (STM), especially for low-"g" Black children. Meta-analysis convincingly shows high…

Infants parse speech into word-sized units according to biases that develop in the first year. One bias, present before the age of 7 months, is to cluster syllables that tend to co-occur. The present computational research demonstrates that this statistical clustering bias could lead to the extraction of speech sequences that are actual words,…

Individuals with autistic spectrum disorders (ASDs) often experience, describe and exhibit unusual patterns of sensation and attention. These anomalies have been hypothesized to result from overarousal and consequent overfocused attention. Parents of individuals with ASD rated items in three domains, "sensory overreactivity",…

Purpose: This article focuses on the sustainability of reform through the lens of teachers' nostalgia--the major form of memory among a demographically dominant cohort of experienced older teachers. Unwanted change evokes senses of nostalgia for these lost missions that take two forms: social and political. As teachers age, their responses to…

A recent study suggests that lesions to all major areas of the cholinergic basal forebrain in the rat (medial septum, horizontal limb of the diagonal band of Broca, and nucleus basalis magnocellularis) impair a spatial working memory task. However, this experiment used a surgical technique that may have damaged cerebellar Purkinje cells. The…

The amygdala appears necessary for enhanced long-term memory associated with emotionally arousing events. Recent brain imaging investigations support this view and indicate a sex-related hemispheric lateralization exists in the amygdala relationship to memory for emotional material. This study confirms and further explores this finding. Healthy…

Several studies support that stored memories undergo a new period of consolidation after retrieval. It is not known whether this process, termed reconsolidation, requires the same transcriptional mechanisms involved in consolidation. Increasing evidence supports the participation of the transcription factor NF-[Kappa]B in memory. This was…

The primary purpose of this study was to test two hypotheses proposed by Bracken and McCallum (1998), authors of the Universal Nonverbal Intelligence Test (UNIT), as to how children diagnosed with ADHD would perform on the UNIT. Twenty-nine students between the ages of 5 and 17 years were administered the extended battery of the UNIT twice, with…

The confounding of chronological and educational age and of schooling and socioeconomic status are persistent problems in the study of the cognitive consequences of schooling. The educational system among the Kharwar in India provides a natural experiment to overcome these problems, since it shows neither source of confounding. The sample…

A sample of 60 children in Grade 3 was followed over one year. In the first year, an extensive battery of assessments was used including aspects of reading, arithmetic, and working memory. Teachers rated the children on 7-point scales on various motivational dimensions summarized to a total score tentatively called task orientation. In the…

Purpose: This study examined the cognitive demands of 2 selection techniques in augmentative and alternative communication (AAC), direct selection, and visual linear scanning, by determining the memory retrieval abilities of typically developing children when presented with fixed communication displays. Method: One hundred twenty typical children…

Purpose: This study explored the effect of frequency (number of presentations), and spacing (period between presentations) on verb learning in children with specific language impairment (SLI). Children learn words more efficiently when presentations are frequent and appropriately spaced, and this study investigated whether children with SLI…

Public education about memory was evaluated with a controlled intervention trial. Participants in group 1 (n = 273) attended a symposium covering memory-related topics and received a magazine with identical information. Group 2 (n = 141) only received the magazine. Participants were nonprofessionals and professionals aged between 29 and 88.…

This study involved fourth grade children as co-researchers of their engaged, aesthetic reading experience. As members of the "Readers as Researchers Club," they documented their engagement with text--how they create, enter, and sustain the story world. The children, who self-identified as avid readers, explored the activities central to their…

The Second World War stands as the most devastating and destructive global conflict in human history. More than 60 nations representing 1.7 billion people or three quarters of the world's population were consumed by its horror. Not surprisingly, therefore, World War II stands as a landmark episode in history education throughout the world and its…
