Perceptions of the organizational context and psychological contract breach: Assessing competing perspectives

This study examines how employees’ perceptions of specific features of the organizational context—organizational politics and procedural justice—are related to their evaluations of psychological contract breach and subsequent attitudes and behaviors. Across three studies, we examined the appropriateness of four models for describing relationships among the focal constructs. Results of these studies support (a) an environmental responsiveness model in which psychological contract breach mediates the effects of politics and justice on employee outcomes, and (b) a general fairness evaluation model where politics, justice, and psychological contract breach serve as indicators of a higher order factor that predicts employee attitudes and behavior. Implications and directions for future research are presented.     

Single-probe serial position recall: evidence of modularity for olfactory, visual, and auditory short-term memory

The present study examined and compared order memory for a list of sequentially presented odours, unfamiliar faces, and pure tones. Employing single-probe serial position recall and following a correction for a response bias, qualitatively different serial position functions were observed across stimuli. Participants demonstrated an ability to perform absolute order memory judgments for odours. Furthermore, odours produced an absence of serial position effects, unfamiliar faces produced both primacy and recency, and pure tones produced recency but not primacy. Such a finding is contrary to the proposal by Ward, Avons, and Melling (2005) that the serial position function is task, rather than modality, dependent. In contrast, the observed functions support a modular conceptualization of short-term memory (e.g., Andrade & Donaldson, 2007; Baddeley & Hitch, 1974), whereby separate modality-specific memorial systems operate. An alternative amodal interpretation is also discussed wherein serial position function disparities are accommodated via differences in the psychological distinctiveness of stimuli (Hay, Smyth, Hitch, & Horton, 2007).     

A Role for the X Chromosome in Sex Differences in Variability in General Intelligence?

ABSTRACT— There is substantial evidence that males are more variable than females in general intelligence. In recent years, researchers have presented this as a reason that, although there is little, if any, mean sex difference in general intelligence, males tend to be overrepresented at both ends of its overall distribution. Part of the explanation could be the presence of genes on the X chromosome related both to syndromal disorders involving mental retardation and to population variation in general intelligence occurring normally. Genes on the X chromosome appear overrepresented among genes with known involvement in mental retardation, which is consistent with a model we developed of the population distribution of general intelligence as a mixture of two normal distributions. Using this model, we explored the expected ratios of males to females at various points in the distribution and estimated the proportion of variance in general intelligence potentially due to genes on the X chromosome. These estimates provide clues to the extent to which biologically based sex differences could be manifested in the environment as sex differences in displayed intellectual abilities. We discuss these observations in the context of sex differences in specific cognitive abilities and evolutionary theories of sexual selection.     

Maternal styles in infant psychotherapy: Treatment and research implications

Infant psychotherapy, in which the mother is requested to follow the baby's activities without initiating or directing, is described. Mothers demonstrate different styles of involvement with their infants: a protective mode, a prohibitive mode, a competitive mode, and other ways of interfering with their infants' tendency to explore the environment. Attempts to analyze such factors as position, distance and movement are discussed. Research for recording and analyzing the movement of infant and mother dyads is proposed.
