Investigated performance on Russell revision of Wechsler Memory Scale and Digit Span subtest of Wechsler Adult Intelligence Scale by right-handed males with lateralized anterior and posterior brain lesions. Prediction that laterality and caudality of lesions would affect memory task performance was fully supported for the logical memory task and…

Illustrates the applicability of temperamental constructs to personality theory by mapping key temperament constructs onto Cognitive-Experiential Self-Theory (CEST). Examines the role of temperament in shaping experiences, and looks at the implications for education and socialization that stem from the synthesis of temperament constructs and…

States that key aspects of "memoria," the ancient Art of Memory, especially its focus on vivid representational images set against distinct backgrounds, can be helpful in creating memorable, universal, and easily retrievable computer icons. (PA)

Examined the nature of three- and four-year-olds' understanding of various mental representations, using story protagonists who held mental representations (beliefs, pretenses, and memories) that contradicted reality. Results suggest that young children conceptualize pretense as involving mental representations and that they have more difficulty…

This study investigated (1) whether attention deficit/hyperactivity disorder (AD/HD) is associated with executive functioning (EF) deficits while controlling for oppositional defiant disorder/conduct disorder (ODD/CD), (2) whether ODD/CD is associated with EF deficits while controlling for AD/HD, and (3) whether a combination of AD/HD and ODD/CD…

Purpose: Diagnosis of dementia in its early stages presents a window of opportunity for examining the immediate and long-term consequences of the illness at a point when the individual with memory loss can still participate in decision making. Design and Methods: Memory Club is a l0-session group program designed to provide information about…

Using transfer methodology, several possible factors that could have affected the expression of serial position learning were examined with runway-trained rats. A 3-trial series (SNP) --for which S and P refer to series trials when sucrose (S) and plain (P) Noyes pellets were used as a reward, and N refers to a trial without reward -- was the…

Research on memory development has increasingly moved out of the laboratory and into the real world. Whereas early researchers asked whether confusion and susceptibility to suggestion made children unreliable witnesses, furthermore, contemporary researchers are addressing a much broader range of questions about children's memory, focusing not only…

In antisaccade tasks, subjects are required to generate a saccade in the direction opposite to the location of a sudden-onset target stimulus. Compared to young adults, older adults tend to make more reflex-like eye movements towards the target, and/or show longer saccadic onset latencies on correct direct antisaccades. To better understand the…

Fragile X syndrome is a neurodevelopmental disorder that is caused by large methylated expansions of a CGG repeat (>200) region upstream of the FMR1 gene that results in the lack of expression of the fragile X mental retardation protein (FMRP). Affected individuals display a neurobehavioral phenotype that includes a significant impairment in…

We investigated the effect of familiarity on people's perception of facial likeness by asking participants to choose which of two mirror-symmetric chimeric images (made from the left or right half of a photograph of a face) looked more like an original image. In separate trials the participants made this judgment for their own face and for the…

Are the linguistic forms that are memorized in the mental lexicon and those that are specified by the rules of grammar subserved by distinct neurocognitive systems or by a single computational system with relatively broad anatomic distribution? On a dual-system view, the productive -ed-suffixation of English regular past tense forms (e.g.,…

Individuals with Down syndrome suffer from relatively poor verbal short-term memory. Recent work has indicated that this deficit is not caused by problems of audition, speech, or articulatory rehearsal within the phonological loop component of Baddeley and Hitch's working memory model. Given this, two experiments were conducted to investigate…

We adapted a paradigm developed by Clayton and Dickinson (1998), who demonstrated memory for what, where, and when in scrub jays, for use with rhesus monkeys. In the study phase of each trial, monkeys found a preferred and a less-preferred food reward in a trial-unique array of three locations in a large room. After 1h, monkeys returned to the…

A growing body of research has emphasized the linkage between performance in immediate serial recall of lists, nonword repetition, and word learning. Recently, it has been reported that primacy and recency effects are obtained in repetition of individual syllables within nonwords (Gupta, in press). Five experiments examined whether such…
