Three experiments involved imagining the result of either an array rotating relative to a fixed viewer or a viewer rotating relative to a fixed array. The data suggested that adults use literal, concrete strategies to solve these problems. (Author/PN)

In this study self-concept, as measured by subjects' self-ratings of mechanical ability, was correlated to scores on the Pourchot Mechanical Manipulation Test of bilateral hand tool dexterity. Significant relationships were found. Subjects, ages 10-84, differed in results by age, sex, and mechanical experience. (SJL)

Children, ages 7 and 11, were asked to manipulate strips of cardboard into outlines of ideas and objects. Responses were categorized to show if novel configurations appeared and developed and if this phenomenon was a function of creative thinking as measured by Torrance's Figural Test, Form B. (Author/SJL)

The study explored the concept of space through the tactual discrimination of household objects in 48 4-to-7-year-old blind, partially sighted, and sighted children. (PHR)

Three third graders with a history of low achievement in math were first given verbal (abstract) instruction in solving word problems. Students were then introduced to manipulatives instruction using Cuisenaire rods to set up word problems. Students exhibited immediate and sustained improvement on subsequent probes administered without…

The authors examined the prioritization of abruptly appearing objects in real-world scenes by measuring the eyes' propensity to be directed to the new object. New objects were fixated more often than chance whether they appeared during fixations (transient onsets) or saccades (nontransient onsets). However, onsets that appeared during fixations…

False memories are often demonstrated using the misinformation paradigm, in which a person's recollection of a witnessed event is altered after exposure to misinformation about the event. The neural basis of this phenomenon, however, remains unknown. The authors used fMRI to investigate encoding processes during the viewing of an event and…

Examined in a longitudinal study of children were correspondences and correlations between early language development on the one hand, and the manipulation of objects and play development on the other. There were developmental correspondences between the onset of five language landmarks (the emergence of first word, referential word, demonstrative…

Two experiments show that action alters the shape categories formed by 2-year-olds. Experiment 1 shows that moving an object horizontally (or vertically) defines the horizontal (or vertical) axis as the main axis of elongation and systematically changes the range of shapes seen as similar. Experiment 2 shows that moving an object symmetrically (or…

Age-related characteristics of children's short-term retention of kinesthetic movement information were examined in this study. Three age levels (6-, 8-, and 10-year old children) were tested for recall of preselected location movements on a linear slide apparatus. Immediate and delayed recall were used in 16 trials. The results indicate that…

A seriation task (assembling a set of nesting cups) was used in this study to examine developmental changes in young children's ability to restructure a situation. Forty young children, eight each at 18, 24, 30, 36, and 40 months of age, participated in the study. Each child was presented with five nesting cups and was told he or she could play…

The purpose of the present study was to determine whether playing a specific ball sport, such as tennis, could maintain the coincidence-timing (CT) performance of older adults at a similar level to that of younger ones. To address this question, tennis players and nonplayers of three different age ranges (ages 20-30, 60-70, and 70-80 years)…

The purpose of this study was to explore how children use location and distance cues to reproduce movements as compared with adults. Subjects were three groups of children, aged 6, 8, and 10, and one group of adults. A linear slide was used by the blindfolded subjects to indicate one of two experimenter-defined stops. Distance and location were…

Explores the relation between the infant's ability to negotiate the environment and the quality of the infant-mother attachment relationship. (HOD)

Tests hypotheses that social and object skills can be equated for cognitive complexity and that correlations between measures organized according to levels are high for all samples spanning the developmental range. Cognitive levels of both object and social skills were assessed for 50 normal and 34 handicapped children. Hypotheses were confirmed.…
