Adults in their twenties and sixties were tested for free recall, cued recall, and recognition of words that they had studied in an intentional memory task or generated associations to in an incidental orienting task. Significant age-related declines in performance on intentional items were observed regardless of type of memory test. (Author)

Performance on Piagetian logical concept tasks, standardized intellectual measures, and measures of memory ability was assessed cross-sectionally. Factorial analyses revealed significant chronological age main effects for all tasks except transitivity of weight. Covariance analyses indicated educational level is generally more closely related to…

Reports three experiments which investigated the ability of children aged four to nine years to organize body-location information in recall. Attempted to correct for methodological confounding in previous similar research. (JMB)

Although it has been suggested that sleep, and particularly REM (rapid eye movement) sleep, plays an important role in information processing, this study found no relationship between any aspect of sleep, in particular time of arousal during the week and on weekends, and academic performance.

Two groups of retarded adults were trained to use a cumulative rehearsal strategy for a serial recall task. Subjects who received instructions emphasizing the intended purpose and potential uses of the trained strategy performed significantly better than subjects invited to participate in "a remembering task." (Author/SJL)

The effects of subsequent related information and cognitive flexibility on prose recall were studied. Subjects read a passage; then were given either consistent or contradictory information. Errors in cued recall, reflecting the subsequent information, were more frequently produced after a three-week delay than after two days. (Author/GDC)

An examination of the role of metacognitive thinking (a secondary level of understanding in which an individual shows knowledge of his/her own cognitive process and products) in the cognitive training of exceptional students is presented. (PHR)

The article provides a rationale for the consideration of the processing differences of exceptional learners and discusses how these differences influence the development of the skills necessary for normal school achievement. (PHR)

Category theory concept of a commutative diagram was used to construct a model of the way in which symbolic processes are applied to problem solving. It was shown that several different levels of thought can be distinguished within the basic model. Two experiments testing the theory are reported. (Author/RD)

Two studies investigated the possibility that assessment of confidence is biased by attempts to justify chosen answers. These attempts include selectively focusing on evidence supporting the chosen answer and disregarding contradictory evidence. Results suggest that confidence depends on the amount and strength of evidence supporting the answer…

Two experiments found that integration of facts alleviates interference only when a person can perform a memory task by making a consistency judgment and can avoid the need to retrieve a specific fact. People judge themes rather than facts: the more themes associated with a concept, the greater the interference. (Author/RD)

Age significantly predicted performances on six memory tests which clearly defied verbal labeling. Low scores of older persons were responsible for the age effect. The progressively lower recognition scores suggested that nonverbal memory processing through all three modalities was affected adversely by age. (Author)

Elderly subjects demonstrated significantly greater levels of persistence. Contrast relationship of the target stimulus and its background did not interact with age. Although the data were consistent with a hypothesis of increased persistence of stimuli in the senescent nervous system, problems in the direct measurement technique are evident.…

A sample of 201 high school students was given a battery of 27 ability tests strategically chosen to provide composite measures of 12 primary mental abilities selected to indicate second-order abilities known as fluid intelligence (Gf), crystallized intelligence (Gc), and short-term acquisition retrieval (SAR).
