A study presented four groups of chess players (child experts and novices, adult experts and novices) with short-term memory tasks involving meaningful and random chess positions, as well as a control board composed of geometric-shaped spaces and pieces. Found that child experts' immediate recall for meaningful chess positions was far superior to…

Examined memory of 3- to 18-year-olds with leukemia regarding lumbar punctures (LP). Found that children displayed considerable accuracy for event details, with accuracy increasing with age. Use of Versed (anxiolytic medication described as a "memory blocker") was not related to recall. Higher distress predicted greater exaggerations in…

To examine possible explanations of reported inaccuracies of children with specific language impairment (SLI) on nonword repetition, study compared repetitions of 54 SLI children and peers for number and type of error, latency, and duration of response. Found no evidence of differences between groups in auditory discrimination or response…

Two studies investigated whether language-specific patterns encoding manner and direction of motion in English and Greek affect adult and child speakers' performance on nonlinguistic motion tasks and linguistic descriptions of these motion events. Although the two linguistic groups differed in linguistic preferences, nonlinguistic task performance…

Two experiments compared delayed matching-to-sample (DMTS) accuracy under 2 procedures in adults with mental retardation. In the trial-unique procedure, every trial in a session contained different stimuli. Thus, comparison stimuli that were correct on one trial were never incorrect on other trials in that session (or vice versa). In the 2-sample…

Ten cerebellar patients were compared to 10 control subjects on a verbal working memory task in which the phonological similarity of the words to be remembered and their modality of presentation were manipulated. Cerebellar patients demonstrated a reduction of the phonological similarity effect relative to controls. Further, this reduction did not…

This study compared Hispanic children (ages 7 to 11) with combined type (CT, n = 33) and inattentive type (IT, n = 21) attention deficit hyperactivity disorder (ADHD) and a control group (n = 25) on time-estimation and time-reproduction tasks. The ADHD groups showed larger errors in time reproduction but not in time estimation than the control…

Generation enhances memory for occurrence but may not enhance other aspects of memory. The present study further delineates the negative generation effect in context memory reported in N. W. Mulligan (2004). First, the negative generation effect occurred for perceptual attributes of the target item (its color and font) but not for extratarget…

This experiment examined the effects of reinforcement probability on resistance to change of remembering and response rate. Pigeons responded on a two- component multiple schedule in which completion of a variable-interval 20-s schedule produced delayed matching-to-sample trials in both components. Each session included four delays (0.1 s, 2 s, 4…

The Anamnestic Comparative Self Assessment (ACSA) measure of subjective well-being (SWB) aims to reduce the problems of cultural bias and relativity to external standards by allowing people to define the endpoints or "anchors" of the measurement scale. In medical terminology anamnestic denotes "based on memory". The ACSA uses…

Background: Co-morbidity of attention deficit hyperactivity disorder (ADHD) and reading disorder (RD) is frequent. The objective of this investigation was to assess the potential uniqueness of co-morbid ADHD + RD and extend existing findings to the Hebrew language. Method: A parallel group design with post-hoc analysis of group differences was…

This study investigated the effects of organization at input and cued retrieval on the free- and cued-recall memory performance of children (all male and between the ages of 8 and 12) with and without attention deficit/hyperactivity disorder (ADHD). Children with ADHD (N=20) recalled significantly fewer words/pictures than children without ADHD…

Two studies examined the effects of on-line processing and memory-based processing on the transfer of analogy problem-solving strategies. Male and female college students (N=189) were randomly assigned to one of three experimental groups and a control group. Each experimental condition involved a different type of training strategy (advice,…

This essay considers whether the brain can accelerate the speed with which it absorbs or dispenses information in ways similar to those of a computer, and, if so, whether any of these speed-up approaches increase the speed of the processing of the information in the brain. It is suggested that there are tasks for which speed is important in both…
