Control of social desirability in personality inventories: Principal-factor deletion

Rational and statistical techniques for controlling social desirability (SD) in scales derived from self-report inventories are reviewed. The principal-factor deletion technique is explained in detail. It is applied during factor analysis when derived content scales are expected to be tainted with SD. If one principal factor is found to represent social desirability, the implicated factor is dropped and the communalities adjusted before the remaining factors are rotated to a desired simple structure criterion. Subscales derived from resulting factors are free of SD bias. Principal-factor deletion is compared with other approaches including rational techniques, covariate procedures, and target rotation.     

Modality-specific information processing and intellectual ability

Two groups of children, one of below average intelligence and one of above average intelligence, were adminitered nine tasks involving matching information between auditory and visual modalities and temporal and spatial presentations. The below average intelligence children made more matching errors than the above average intelligence group, with no indication that matching problems were particular to one modality or particular to cross-modal as opposed to intramodal matching. Factor analyses did suggest, however, that matching processes varied according to levels of intelligence. The results are discussed in terms of the differences between modality-specific and nonmodal theoretical views of sensory systems, and it is noted that neither view alone is adequate to account for the variations found for the two intelligence groups. It is suggested that the results are consistent with Luria's research on neurological organization.     

Effects of imaginal exposure to feared disasters in obsessive-compulsive checkers

The combined effects of imaginal exposure to feared catastrophes and in vivo exposure to external stimuli were compared with the effects of in vivo exposure alone in 15 obsessive-compulsives with checking rituals. The first group received 90 min of uninterrupted exposure in imagination, which concentrated mainly on disastrous consequences, followed by 30 min of exposure in vivo to stimuli-situations which triggered rituals. The second group was given 2 hr of exposure in vivo only. Both groups were prevented from performing rituals. Treatment consisted of 10 daily sessions within a 2 week period.Assessments were conducted before and after treatment and at follow-up ranging from 3 months to 2.5 yr with a mean of 11 months. At post-treatment both groups improved considerably and did not differ. But at follow-up those who received imaginal and in vivo exposure maintained their gains, whereas the group who were treated by exposure in vivo alone evidenced partial relapse on four of the six dependent measures. The results tend to indicate that a closer match between a patient's internal fear model and the content of exposure enhances long term treatment efficacy.     

Constraints on Pavlovian aversive conditioning: Implications for avoidance learning in the rat

Four experiments investigated the relative degree of control exerted by several conditional stimuli when each stimulus: (a) preceded shock, (b) followed shock, and preceded a shock-free interval, (c) was independent of shock, or (d) was novel. When the onset of an auditory stimulus had preceded shock (Experiments 1, 2A, and 3), it always exerted conditioned excitatory control. When the same stimulus preceded a shock-free interval, it never exerted conditioned inhibitory control. When the onset of light (Experiments 2B, 4), silence (2C), or darkness (1, 2D) preceded a shock-free interval, it always exerted conditioned inhibitory control. However, when one of the latter stimuli preceded shock, it failed to exert excitatory control. Several models of this phenomenon were tested. The implications of these results for the species-specific defence reaction and two-factor theory accounts of avoidance learning were outlined.     

Development of classification: The use of similarity and dimensional relations

Findings about perceptual development indicate that overall similarity is the primary perceptual relation by which young children compare complex objects. Traditional studies of classification, however, did not focus on children's organizational use of holistic relations but rather on their ability to classify by dimensions or criterial attributes. The results from such traditional studies suggest that young children are deficient classifiers. The present research investigated the possibility, contrary to the traditional view, that 4- to 6-year-old children are competent and systematic classifiers at least by overall similarity. In three experiments, preschoolers and kindergarteners classified various sets of multidimensional stimuli that could be organized into categories by overall similarity or by dimensional attributes. Consistent with the research in perceptual development, the children were highly attentive to overall similarity. However, the preschoolers in particular showed marked difficulty in using this relation to form categories of more than two objects. The children's difficulties were highly reminiscent of traditional claims about early classification. Analyses of the classification strategies used by the children, however, suggest that even the youngest children understood the purpose of a classification. The developmentla changes appear to be in the ability to execute a classification. Importantly, type of classification strategy was independent of type of category organization. Individual children used the same strategies both when classifying by overall similarity and by dimensional attributes. These results strongly suggest that it is the classification skills themselves, and not just the ability to classify by particular relations, that change with age.     

Cross-modal transfer and intermediate-size transposition

Kindergarten and third grade boys learned an intermediate-size problem either visually or tactually. They were then tested either visually or tactually. The test sets were separated from the training set by either 1, 2, or 4 steps. The data supported predictions derived from the D. M. Lane and F. M. Rabinowitz (Child Development 1977,48, 412–426) transposition theory on choice and consistency measures. Of greatest interest were the markedly different transposition gradients exhibited by the boys in the visual-visual and visual-tactual groups.     

Construct validation of the dependency and self-criticism scales of the depressive experiences questionnaire

S. J. Blatt (Psychoanalytic Study of the Child, 1974, 29, 107–157) distinguished between two types of depressive experiences, one characterized by strong dependency needs and the other by self-criticism and guilt. This paper reports a series of validation studies of the Depressive Experiences Questionnaire (DEQ), which was developed to measure individuals' vulnerabilities to these types of experiences (S. J. Blatt, J. P. D'Afflitti, & D. M. Quinlan, Journal of Abnormal Psychology, 1976, 85, 383–389). The Dependency and Self-Criticism scales were shown to be stable in the face of both a 13-week interval and the receipt of midterm grades. Dependency was associated with conflict concerning the expression of hostility and, in males, feelings of helplessness. Self-Criticism was associated with low self-esteem and high levels of morality-conscience guilt. In a study of behavior in dyadic problem-solving tasks, Dependency in males was found to be negatively related to task leadership, and Self-Criticism in females tended to be negatively related to judged likeability. On the other hand, little support was found for the hypotheses that Dependency would be related to field dependent cognitive style and to the use of primitive defense mechanisms. The results were viewed as supporting the utility of Blatt's distinction between the two types of depression, but a number of anomalous findings indicated a need for further study of the DEQ. The question of the developmental level of the two types of depression, possible sex differences in the correlates of the scales, and the possibility of situational specificity in individuals' responses were identified as the areas most in need of study.     

B. F. Skinner and G. H. Mead: on biological science and social science.

Skinner's contributions to psychology provide a unique bridge between psychology conceptualized as a biological science and psychology conceptualized as a social science. Skinner focused on behavior as a naturally occurring biological phenomenon of interest in its own right, functionally related to surrounding events and, in particular (like phylogenesis), subject to selection by its consequences. This essentially biological orientation was further enhanced by Skinner's emphasis on the empirical foundations provided by laboratory-based experimental analyses of behavior, often with nonhuman subjects. Skinner's theoretical writings, however, also have affinity with the traditions of constructionist social science. The verbal behavior of humans is said to be subject, like other behavior, to functional analyses in terms of its environment, in this case its social context. Verbal behavior in turn makes it possible for us to relate to private events, a process that ultimately allows for the development of consciousness, which is thus said to be a social product. Such ideas make contact with aspects of G. H. Mead's social behaviorism and, perhaps of more contemporary impact in psychology, L. Vygotsky's general genetic law of cultural development. Failure to articulate both the biological and the social science aspects of Skinner's theoretical approach to psychology does a disservice to his unique contribution to a discipline that remains fragmented between two intellectual traditions.
