Asymmetry of perception in free viewing of chimeric faces

We have devised a new free-vision task to index functional cerebral asymmetry for processing facial characteristics. Confirming its sensitivity to properties of lateralized hemispheric functions, left- and right-handers were clearly differentiated on this task with respect to several aspects of performance that conform with known differences between handedness groups in hemispheric asymmetry. Additionally, there were highly reliable and stable individual differences in perceptual asymmetries within handedness. Analyses of items in the task revealed that most of the differences between items in the asymmetries they elicited were random.     

Developmental changes in predicting one's own span of short-term memory

Developmental changes in the accuracy of predicting one's own recall were studied, using preschool, third grade, and college subjects in Experiment 1 and third grade and college subjects in Experiment 2. Experiment 1 showed that prediction accuracy increased from the preschool to the college years, subjects were not influenced by a potential “expectancy” bias in the procedure, and only third grade subjects were influenced by the presence of norms about peer performance. Experiment 2 showed that third graders and college subjects lower their predictions in the face of “false” norm information, with college subjects being the only group to under predict actual recall in both experiments. Thus, although adults are significantly more accurate than elementary shool children in estimating short-term recall, their susceptibility to norm information suggests that even they have uncertainty about their exact capabilities.     

Effects of warm and neutral models on the attention of observational learners

The study was conducted to examine observers' attention to adults following warm and neutral interactions with them. Forty-two preschool and 36 third grade girls interacted with a pair of female models in one of three treatment conditions in which models were, respectively, warm and neutral, neutral and neutral, or warm and warm. Subiects then witnessed the models play a picture-preference game and were asked to recall the models' responses. Analyses of the children's overt attention to the models' responses revealed a greater attention to a warm model when in the presence of both a warm and neutral model and less distraction by nonsocial stimuli when at least one warm model was present. A significant positive correlation was obtained between attention to and recall of the models' responses.     

An empirical comparison of theZ-variance and Box-Scheffé tests for homogeneity of variance

This brief report provides a comparison of theZ-variance and Box-Scheffé tests for homogeneity of variance. Both procedures are relatively simple to perform and both may be readily utilized in complex, multifactor designs. TheZ-variance test is not robust against non-normality; the Box-Scheffé test is robust against non-normality but is not nearly as powerful as theZ-variance test.     

DOMINANCE AND INEQUALITY IN X-RATED VIDEOCASSETTES

Feminists have been concerned about the debasement of women in sexually explicit material. The purpose of this study was to determine the extent of domination and sexual inequality in x-rated videocassettes through a content analysis of 45 widely available x-rated videocassettes. The sample was randomly drawn from a list of 121 adult movie titles widely available in family videocassette rental stores in southern California. Over half of the explicitly sexual scenes were coded as predominantly concerned with domination or exploitation. Most of the domination and exploitation was directed by men toward women. Specific indicators of domination and sexual inequality, including physical violence, occurred frequently. The growth of the videocassette rental industry and the popularity of x-rated films, coupled with the messages these films convey, is a cause for concern.     

Reading,spelling, and vigilance in attention deficit and conduct disorder

A group of 51 male children, average age 9.1 years, presenting at a child psychiatric clinic because of attention and conduct problems were investigated for reading and phonetic spelling ability, vigilance, and intellectual level. Each child was given a DSM- III diagnosis prior to being tested. The Boder Test of Reading and Spelling patterns was used to obtain scores for reading age, number of syllables read correctly in the word list at the child's reading level, and number of phonetically correct syllables spelled in the known and unknown word lists, at and just above the child's reading level. A factor analysis with varimax rotation produced two significant factors, a Reading factor with high loadings for verbal and reading scores, aand a second Vigilance factor. Phonetic spelling ability loaded separately from reading into the Vigilance factor. The Vigilance factor was significantly related to the diagnosis of moderate and severe attention deficit disorder with hyperactivity (ADDH). The correlation of short- term working memory with vigilance in moderate to severe ADDH children is discussed.Fundling assistance was provided by the New South Wales Institute of Psychiatry.     

Getting an on-line departmental teaching laboratory on-line

The major problems faced in building a department-wide undergraduate, computer-based teaching laboratory are discussed: selling the concept of the “ultimate dry lab,” assembling the hardware, motivating and rewarding faculty and staff effort, devising a systems approach for curriculum design, and program evaluation.     

PROPERTIES OF THE HOLLEY-GUILFORD 'G INDEX OF AGREEMENT' IN R AND Q FACTOR ANALYSIS

The Holley-Guilford G index for 2×2 contingency tables has spatial properties which suggest that, as with other such indices, problems may arise in factor analysis of G matrices. Two response models—Guttman's Simplex and the Coombs-Kao conjunctive case—are used to provide data for exploring the behaviour of G. In particular, the claim that G equates person means and variances in Q analysis is not substantiated.     

Therapeutic strategy and psychoanalytic technique

The role of therapeutic strategy within psychoanalytic technique is described. An antistrategic bias inherent in certain aspects of the "classical" technique is explored in relation to the historical development of psychoanalysis. Clinical expertise, which includes the making of strategic or tactical choices, is relegated to the "unofficial," due in part to this negative bias impeding the study of technical differences in favor of general agreement about a theory of technique that may differ considerably from actual clinical work. A case is presented that illustrates strategic choices in the management of a severe character resistance in a supervised analysis. Some consequences of a negative bias against therapeutic strategy as it relates to psychoanalytic training is described.
