Reports results of short-term training procedures upon the acquisition of the concept of conservation in children. (DR)

Scores of three rating scales indicated that a disparity exists between counselors' and patients' perceptions of the latter's therapeutic environment. (CK)

Since 1965, Professor Revans has been Senior Research Fellow in the European Association of Management Training Centres, specializing in the application of analytical methods to an understanding of industrial morale. (EB)

Three experiments on tachistoscopic perception of visual stimuli demonstrate that the visual system is sensitive to global topological properties. The results indicate that extraction of global topological properties is a basic factor in perceptual organization. (Author)

An open-ended interview, a picture-recognition task, and a forced-choice rating task were administered to 64 four- to seven-year-old boys and girls to assess development of conceptions of friendship. Findings suggested that as children grow older they place increasing emphasis on affectively based friendship characteristics. (Author/MP)

In three studies, 12-month-old infants were familiarized either tactually or visually with objects and were then tested for visual recognition memory using either (1) the familiar and a novel object, (2) colored pictures of the objects, or (3) outline drawings of the objects. (Author/MP)

Examines the ability of infants ranging in age from 21 to 44 hours old to discriminate among visual stimulus arrays. Infants were able to discriminate between small sets of dots (two to three dots) but not between larger sets (four to six). (Author/MP)

Holograms of faces were used to study two- and five-month-old infants' discriminations of changes in facial expression and pose when the stimulus was seen to move or to remain stationary. While no evidence was found suggesting that infants preferred the moving face, evidence indicated that motion contrasts facilitate face recognition. (Author/RH)

Examines the validity of three dimensions of aesthetic perception: hedonic value, arousal, and uncertainty. Hedonic interest and arousal factors were found to differ from factors previously reported, while the uncertainty factor paralleled that previously reported. (Author/RH)

Two groups of 15 children (7 to 9 years old) were compared on auditory perceptual skills and academic achievement. Ss with conductive loss (CL) had histories of middle ear pathology. Overall performance of the CL Ss was significantly lower than a normal control group's, with specific deficiencies in auditory perceptual areas. (CL)

The meaning of mothers' perceptions of their infants' temperamental "difficultness" was explored in three ways. Subjective ratings were elicited from mothers who listened to the cries of four- to six-month-old infants who were not their own. Acoustic properties of the cries of the infants were measured and effects of a variety of…
