Social processing errors among paranoid personalities

The present study tested clinical hypotheses about the social processing attributes of paranoid personalities (PP). Eighteen PPs and 18 normal controls (NC) viewed standardized role plays (Dodge, 1986) in which a provocation occurred but the protagonist's intention varied (i.e., ambiguous, accidental, hostile, or prosocial). Subjects identified the intention behind the action and then chose a response to that action (e.g., ignore what he did). The results indicated that PPs and NCs did not differ on intentioncue detection when the intention was clear, but PPs had a significantly higher rate of misreading ambiguous situations. Furthermore, when intentions were ambiguous, PPs were more likely than NCs to identify them as hostile intentions. Finally, PPs' reactions to the vignettes were different from normal controls' when the perceived intention was either prosocial or accidential. PPs were more likely to respond with anger and less likely to ignore the event, compared to NCs. These data provide initial support for clinical notions about the aberrant social processing of paranoid personalities.     

A behavioral analysis of peaking in residential electrical-energy consumers

This study was concerned with "peaking", which is the tendency for electrical-energy users to consume at high rates for brief periods during the day. Peaking results in the inefficient use of generating facilities, which may lead to unfavorable effects on the environment, such as the construction of new energy producing facilities or the activation of older, less safe, generating units. A continuous data collection system to monitor consumption of electrical energy was installed in the homes of three volunteer families. Information, feedback, and incentives were evaluated for their effects on peak energy consumption. A combination of feedback plus incentives was most effective and reduced peaking about 50%. Removal of experimental treatments resulted in a return to pre-treatment patterns of consumption.     

Birth order and selected work-related personality variables

A possible link between birth order and various individual characteristics (e. g., intelligence, potential eminence, need for achievement, sociability) has been suggested by personality theorists such as Adler for over a century. The present study examines whether birth order is associated with selected personality variables that may be related to various work outcomes. 3 of 7 hypotheses were supported and the effect sizes for these were small. Firstborns scored significantly higher than later borns on measures of dominance, good impression, and achievement via conformity. No differences between firstborns and later borns were found in managerial potential, work orientation, achievement via independence, and sociability. The study's sample consisted of 835 public, government, and industrial accountants responding to a national US survey of accounting professionals. The nature of the sample may have been partially responsible for the results obtained. Its homogeneity may have caused any birth order effects to wash out. It can be argued that successful membership in the accountancy profession requires internalization of a set of prescribed rules and standards. It may be that accountants as a group are locked in to a behavioral framework. Any differentiation would result from spurious interpersonal differences, not from predictable birth-order related characteristics. A final interpretation is that birth order effects are nonexistent or statistical artifacts. Given the present data and particularistic sample, however, the authors have insufficient information from which to draw such a conclusion.     

Goal utility, task satisfaction, and the self-appraisal hypothesis of type A behavior

Strube's (1987) self-appraisal model of Type A behavior suggests that externally mediated performance goals that are useful for assessing task-related competencies will possess greater utility and be more satisfying to Type A persons than to Type B persons. In contrast, because Type Bs may have an aversion to competency verifications, they should be more satisfied than Type As when goals are uninformative about task-related competencies. The 102 undergraduate Ss performed either a word puzzle or proofreading task under 1 of 4 goal conditions that varied in terms of the goal's instrumentality for assessing competencies and for obtaining a financial incentive. Results are generally consistent with this prediction, thereby providing verification for one of the more basic propositions derived from the self-appraisal model.     

Real and ideal self-images in second- and fifth-grade children: Reliability,validity and factorial structure

The reliability, construct validity, and factorial structure of three self-image instruments were assesses in a total of 80 second- and fifth-grade children. Both real self-images (children's current views of themselves) and ideal self-images (the self views to which children aspire) were assessed. the split-half and test—retest reliabilities of the instruments were adequate even for children's as young as second graders. Stronger evidence of construct validity was found for the older children, although the intercorrelation patterns for both age groups were characterized by larger correlations between assessments of real and ideal self-images using the same instrument than between assessments of the same component of the self-image across the three instruments. Contrary to predictions gener ated by developmental theory, the factor analyses provided non evidence of increasing differentiation of the self-image with age. They did, however, reveal that second and fifth graders distinguish distinctly different functional domains within their self-images.     

The step cycle organization of infant walkers

To walk independently, the human infant must coordinate its multisegmented body to achieve both postural stability and forward mobility. In this experiment, we sought evidence of the form this coordination takes in infants who have been walking 3 to 10 months. Using the Philippson phases to represent the step cycle, we analyzed film records of infants and adults walking at speeds from 2 to 4 km/hr. Our results reveal a clear relationship between walking speed and the F and E(3) Philippson phases of the step cycle in both the young walkers and the adults. Indeed, across all four phases of the step cycle, the infants exhibited an organization that was almost identical to that of the mature walkers.
