Examined the possible facilitating effect of thematic materials in Wason's selection task. Two experiments failed to replicate previous findings. In support of a memory-cueing hypothesis, improved performance was found for an implication rule that was part of subjects' past experience. (Author)

Describes how a behavioral system in Aplysia (marine snail) can be used to examine mechanisms of several forms of learning at different levels of analysis: behavioral, cell-physiological, ultrastructural, and molecular. Focusing on short-term sensitization, suggests how molecular mechanisms can be extended to explain long-term memory and classical…

Two metacognitive strategies, ARROW and BRIDGE, are presented that can be taught to students with language-based learning disabilities to help them manage the long-term memory demands of middle school and high school curricula. A metastrategy is presented that is designed to facilitate the development of strategic problem solving. (Author/CR)

Five experiments examined the role of global and local cues in memory retrieval in infancy. Results showed that infants encode and remember for substantial periods of time not only the shape of figures displayed in their periphery but also the global organization of these figures. They also adapt this information when responding to new events.…

Two experiments examined causal links among age, processing time, articulation time, and memory span in elementary school children. Found that age was correlated posssitively with memory span but negatively with processing and articulation times and that age-related change in processing time was associated with a decrease in the time required to…

Four questionnaires examined the association of demographic factors with recollection for 768 adults. Found that the age of earliest memory increased across birth order, was slightly earlier for females than for males, and was earlier for Caucasians than for Asians. (Author/BC)

Presents new evidence that everyday mood does bring about a hypothesized effect on memory, termed mood-congruent memory (MCM). Results of three studies provided evidence for MCM among normal individuals (n=614). Findings support prior studies and bolster notions that mood and memory constantly covary in everyday experience.

Two experiments examined the effects of interference on young children's long-term memory using paired-association recall and free recall. The results indicated that children were susceptible to interference, the locus of interference effects was at storage, and that both younger (preschool) and older (kindergarten) children experienced similar…

Two experiments compared recognition memory of 85 nonretarded and 85 mildly mentally retarded adolescents immediately and 1 week after presentation of word stimuli of semantic incidental, nonsemantic incidental, or intentional orienting instructions. Results suggest similar processing in mildly retarded and nonretarded persons, with longer…

Gifted-, normal-, and math-disabled children solved addition problems. Their problem-solving strategies and solution times were recorded. The gifted group showed the most mature distribution of strategy choices, and a verbal counting rate less than 50 percent of the rate of the other groups. (BC)

Examined performance of first through sixth graders on conditional-inference task, using causal conditionals and a generation of alternatives task. Found a steady age-related increase in uncertainty responses to two uncertain logical forms and an increase in production of disabling conditions for "modus ponens." Individual differences in inference…

Investigates the instructional effect of using selected testing sequences and gaming methods on students' delayed retention. Results of instructional treatments and criterion tests of 87 students indicated significant preferences for specific instructional strategies. The treatments were functionally identical in that they did not instigate levels…

Examined effect of familiarization on 3.5-month-olds' retention of visual stimuli with varying delay times. Found support for retention models in which direction of attentional preferences (novel, familiar, or null) depends on memory accessibility. Short lookers showed better retention over time than long lookers, indicating that much of the…

We examined infants' long-term retention of a single unique emotional experience into early childhood. Twenty-month-olds who had participated in a still-face procedure at 5 months (experience group) fixated the face of the person who had instigated the still face significantly less than the faces of 2 other novel persons. Control 20-month-olds…

It is well established that the cerebellum and its associated circuitry are essential for classical conditioning of the eyeblink response and other discrete motor responses (e.g., limb flexion, head turn, etc.) learned with an aversive unconditioned stimulus (US). However, brain mechanisms underlying extinction of these responses are still…
