Points out that children have difficulty learning time concepts. Presents instructional activities for concepts associated with clocks, calendars, and chronology. Outlines Jerome Bruner's three different stages of representation for each concept: enactive, iconic, and symbolic. (DB)

Attaining the insight needed to solve the Mutilated Checkerboard problem, which requires discovery of an effective problem representation (EPR), is described. Performance on insight problems can be predicted from the availability of generators and constraints in the search for an EPR. Data for 23 undergraduates were analyzed. (TJH)

Fourteen teenage or young adult males disabled in print acquisition were studied to determine their patterns of verbal and spatial processing. It was found that, at retest a mean of 5.4 years later, the Similarities score significantly increased while the Vocabulary scores and Acquired Knowledge category actually decreased. (Author/DB)

A visual orienting task was given to 11 high functioning male adolescents and adults with autism. Findings suggested that autistic people have difficulty processing briefly presented cue information and problems disengaging and shifting attention within the visual modality. Results support previous ideas that attentional dysfunction may underlie…

Two experiments used Visual Expectations Procedure to investigate development of expectations in infants up to 12 months old. Reaction time improved and the percentage of anticipations increased between 6 and 9 months using an alternation pattern or a complex pivot pattern, and between 4 and 8 months when using a left-right alternation or a…

Draws on recent work leading to new conceptions of learning, induction, transfer, and strategy acquisition. Contends learning is no longer simply the acquisition of behaviors, but also includes storing knowledge about relations in the world, and acquiring structural representations and mental models. Sees learning and the growth of processing…

Argues that what matters is not the difference between learning and development, but the dynamic relationships that form the key to understanding. Examined two models of these relationships: (1) a semantic approach, distinguishing five dimensions along which learning and development can be compared; and (2) a mathematical nonlinear growth model…

This study assessed use of five computerized analogy problems as a measure of mental speed with 62 children (ages 3-13) with mild/moderate mental retardation. Results found medium to high correlation between scores on the tasks and other cognitive measures and the adaptive behavior scale. The value of assessing cognitive speed in the cognitive…

This study investigated acquisition of music performance skills over 11 practice trials in novice and expert pianists differing in age, training, and sight-reading ability. The finding of a strong positive relationship between the mastery of temporal constraints and planning abilities within performance suggested that these two cognitive…

Electrocortical and behavioral responses of low, moderate, and high physically active older adults where compared with a younger control group on neutral and incompatible conditions of a flankers task. Compared to younger adults, high and moderate active older adults exhibited increased event-related potentials component P3 amplitude for the…

Cognitive research on metaphoric concepts of time has focused on differences between moving Ego and moving time models, but even more basic is the contrast between Ego- and temporal-reference-point models. Dynamic models appear to be quasi-universal cross-culturally, as does the generalization that in Ego-reference-point models, FUTURE IS IN FRONT…

Imaginal perspective switches are often considered to be difficult, because they call for additional cognitive transformations of object coordinates (transformation hypothesis). Recent research suggests that problems can also result from conflicts between incompatible sensorimotor and cognitive object location codes during response specification…

Neuroimaging studies have frequently observed relatively high activity in medial rostral prefrontal cortex (PFC) during rest or baseline conditions. Some accounts have attributed this high activity to the occurrence of unconstrained stimulus-independent and task-unrelated thought processes during baseline conditions. Here, the authors investigated…

Clinical views of neuroticism-linked distress often make reference to the perseverative sorts of mental processes that reinforce such experiences. The goal of the present 7 studies, involving 488 undergraduate participants, was to directly examine such perseverative processes. Individual differences in response perseveration were operationalized…

In a mental rotation task, children 5 and 6 years of age and adults had to decide as quickly as possible if a photograph of a hand showed a left or a right limb. The visually presented hands were left and right hands in palm or in back view, presented in four different angles of rotation. Participants had to give their responses with their own…
