Describes three delayed-response experiments which tested two- and three-year-old children's memories for location of a hidden object under several combinations of spatial and pictorial cue availability and emphasis. (Author/JMB)

Used a modification of Elkind's Picture Integration Test to investigate kindergarten children's perceptual centration in a composite and component picture recognition task. (JMB)

Recorded the pattern of crying in neonates who were responding to natural infant cries, synthetic cries, and silence. (GO)

A statistical technique is proposed for comparing an empirically obtained matrix of the perceived similarity of paired stimuli against a set of distinctive features that supposedly characterize the stimuli on which the matrix is based. The statistical development of the technique and an example are presented. (Author/JKS)

A paradox in studying sensory perception is that people often attend to a stimulus which provides the least optimal information. Usually, this is a visual stimulus. The study sought to lessen this reliance on vision by training subjects to respond to proprioceptive stimuli. Results are discussed. (Author/JL)

The authors describe a project to design a playground at the John de la Howe School in South Carolina using students' ideas. A list of ideas for making a playground into a mentally and physically stimulating environment is included. (CH)

When the effectiveness and mortality-morbidity of electroconvulsive therapy (ECT) are compared with those of drug therapies, it appears that ECT is an effective and preferred treatment strategy. It remains underutilized as a modality of suicide prevention. Addresses controversies that presently limit the use of this treatment. (Author/ABB)

Three variables (diagnosis, location of cues, and mental age of learners) influencing stimulus control and stimulus overselectivity were assessed with eight autistic children (mean age 12 years) and eight average children matched for mean age. Among results were that autistic subjects tended to respond overselectively only in the extra-stimulus…

Studies of orientation perception in infants and children have revealed an "oblique effect," that is, a performance advantage for tasks involving horizontal and vertical stimulus orientations compared with tasks involving oblique orientations. The two studies reported support the hypothesis that oblique stimulus orientations are treated…

Consistent with findings that infants respond to the orientation of a visual stimulus in a categorical-like manner, data obtained from two- and three-month-old infants viewing horizontal/vertical, non-mirror-image oblique, and mirror-image oblique stimulus pairs indicate that elements of oblique/oblique stimulus pairs were more frequently confused…

Results show that at eight months of age ability to identify the site of an event after reorientation is based on the spatial relationship between the event and environmental features. The latter include features associated with room shape as well as a landmark at the site of the event. (Author/RH)

Evaluates infants less than 1 week of age in a habituation-recovery paradigm for evidence of ability to detect an invariant identity or nonidentity relationship between components of a visual stimulus. (Author/NH)

The effect of semantic grouping on confrontation-naming performances of 16 fluent and 10 nonfluent aphasic adults was examined. Performances were not uniformly facilitated in one naming condition over the other. Some patients, however, did appear to display performance discrepancies between the two conditions. (Author/CL)
