Process generalization and the prediction of performance on mental imagery tasks

Kosslyn (1980, 1983) theorized that performance measures on imagery tasks may vary as a function of the existence of independent processes in imaging ability. The present study determined whether improvement can be made in performance on such tasks with practice. It also considered whether performance on such tasks improves with practice and whether this improvement generalizes. Experiment 1 determined whether improvement in a mental rotation task generalizes to improvement in a geometric analogies task, with both tasks weighted in Kosslyn's find process, but not in a line drawing memory task weighted in Kosslyn's regenerate process. In Experiment 2, we examined generalization in improvement from a geometric analogies task to a mental rotation task. In Experiment 3, we tested whether improvement in an animal imagery task (Kosslyn, 1975) generalizes to improvement in a line drawing memory task, with both tasks weighted in Kosslyn's regenerate process, but not to improvement in a mental rotation task. Performance improved with practice on all tasks. Furthermore, performance improved from one task to another only if both tasks loaded on the same process.     

Psychoanalytic training today.

Psychoanalytic education in the United States faces multiple challenges as we enter the last decade of this century. (1) Changing interest and career path patterns for psychiatrists have resulted in fewer medical applications for psychoanalytic training. (2) Increased opportunities for full psychoanalytic training of nonphysicians have resulted in increased applications from highly skilled clinicians who often have more clinical experience than their medical colleagues. (3) Increased enrollment of women candidates has required rethinking of progression requirements, in light of their combined careers as professionals and mothers. (4) Independent institutes not accredited by the American Psychoanalytic Association compete for applicants while maintaining training standards that require less time and immersion in psychoanalytic theory and practice. (5) Economic factors increasingly influence the desirability of prolonged psychoanalytic training and the availability of suitable analysands for control analyses. (6) Evolution of theory and practice and the emergence of "new schools" of psychoanalytic thought have rendered the previous psychoanalytic landscape dominated by drive theory and ego psychology more multifaceted and less uniform. The American Psychoanalytic Association and its institutes attempt to understand these changing patterns and take them into consideration in the design and implementation of psychoanalytic training programs. Only one aspect of this complex situation will be described in this work, the current state of psychoanalytic training in the 28 institutes accredited by the American Psychoanalytic Association. Although the data available at this time leave unanswered many important questions about the philosophies that organize the content and emphases of the curriculum in different institutes, much has been learned about the overall structure of psychoanalytic training programs.     

Lay Explanations of Wealth: Attributions for Economic Success1

The explanations people give for wealth, or financial success, are not only of considerable political importance, but also offer an opportunity to assess some of the implications of attribution theory in a real-lie setting. In the present study, 324 subjects from all walks of life and a variety of socioeconomic and demographic backgrounds were asked to anonymously complete an extensive questionnaire assessing their (a) free response explanations of the most common sources of wealth, (b) estimates of necessary income levels for “wealth” and “a decent life,” and (c) attribution judgments for likely causes of wealth in five target categories of people. The target categories were manipulated in terms of social class and ethnicity, to include native born and migrant, and middle- and working-class characters, as well as attributions to an unspecified other. Results showed that judges used four major attributional categories in explaining wealth (external-social, internal/individual, family background, and luck-risk factors), and that both the target persons' class and ethnicity significantly influenced the attribution strategies used. In addition, the judges' socioeconomic background, demographic position, and voting preferences also significantly affected preferred attributions and estimates of income levels. These results are discussed in terms of the role of social, political, and ideological factors in everyday explanations, and their implications for some assumptions of attribution research are considered.     

Effective elaboration and inferential reasoning

The present study investigated the effects of several variables on subjects’ abilities to draw inferences from two related premises. Contiguous presentation of the related sentences led to significantly higher inference scores than did noncontiguous presentation. The nature of the initial premise was also manipulated. For some subjects, the initial premise was relatively consistent with subjects’ semantic knowledge, whereas other subjects received initial premises that were somewhat arbitrary with respect to semantic knowledge. Inference scores were significantly higher for subjects who received the more consistent initial premises. This effect persists even when differential memory for the initial premises has been accounted for. The results suggest certain constraints on the nature of the knowledge one must possess in order to make appropriate inferences from material.     

The relationship of three measures of childhood depression to academic underachievement

Clinical features of depression (short attention span, lethargy, poor memory and shortened task persistence) appear to be incompatible with effective learning. This has led several investigators to suggest that depression is a significant cause of academic underachievement. The most adequate test of this hypothesis (Tesiny, Lefkowitz, & Gordon, 1980), however, found only small correlations between depression and academic achievement when neither IQ nor socioeconomic status were controlled. In the present study, three measures of childhood depression (Peer Nomination Inventory for Depression, Children's Depression Inventory, and an ad hoc teacher rating) were correlated with scores from the Peabody Individual Achievement Test and the Stanford Achievement Test. IQ was statistically controlled to provide a direct measure of underachievement and analyses were conducted separately for males, females, and the combined sample in a sample that was homogeneous for socioeconomic status. Although intercorrelations among the variables indicated that the sample was appropriate to test the hypothesis, only a few significant correlations were found. These findings suggest that if depression causes academic underachievement, it is a weak or uncommon effect.     

Perception of facial expressions

Three studies examined the nature of the contributions of each hemisphere to the processing of facial expressions and facial identity. A pair of faces, the members of which differed in either expression or identity, were presented to the right or left field. Subjects were required to compare the members of the pair to each other (experiments 1 and 2) or to a previously presented sample (experiment 3). The results revealed that both face and expression perception show an LVF superiority although the two tasks could be differentiated in terms of overall processing time and the interaction of laterality differences with sex. No clear-cut differences in laterality emerged for processing of positive and negative expressions.
