Confirmatory Factor Analysis of Warr,Cook, and Wall's (1979) Job Satisfaction Scale

Warr, Cook, and Wall's Job Satisfaction Scale (JSS) is a widely used measure of job satisfaction in industrial/organisational (I/O) psychology research and practice. However, the factor structure has not been adequately explored, with two‐factor and three‐factor solutions previously proposed. This study tested the factor structure of the JSS using robust analysis methods on data gathered from a convenience sample of 381 (females = 264, males = 116) Australian employees. Confirmatory factor analyses supported a hierarchical three‐factor model of job satisfaction in terms of model adequacy coefficients; however, the three factors were highly correlated, thereby rendering a multifactorial approach to the JSS untenable. The results support the continued use of an overall score of job satisfaction when using this measure in I/O psychology research and practice. Further testing of the structure is recommended within a range of employment sectors, as the assumed multifactorial structure of the JSS common in the literature was not supported by the current study.     

Decision-making by experienced rugby referees: use of perceptual information and episodic memory

The expertise paradigm was used in two studies to examine decision-making by rugby referees. Videoclips were used to assess infraction detection and knowledge base, or sources of information used. In Study 1, referees of high and low experience were compared, and in Study 2 referees and players were compared. Analysis by signal detection used a framework to classify types of information. Study 1 yielded no differences in detection of infractions as a function of experience, however, referees of high experience used significantly more sources of information than the group with low experience across all categories of information. In Study 2, there were no significant differences between referees and players, with the exception that referees displayed greater use of episodic memory information in decision-making.     

An assessment of sleep architecture as a function of degree of handedness in college women using a home sleep monitor

The present study examined sleep architecture as a function of handedness in a population of undergraduate college women using a home sleep monitor. Compared to strongly handed individuals, participants with a tendency toward mixed-handedness had a shorter sleep latency and spent a greater percentage of their sleep period asleep and less awake. Increasing mixed-handedness was also associated with increased NREM; strong-handedness was associated with increased REM. Results are placed in a neurophysiological framework wherein corpus callosum mediated differences in interhemispheric interaction during Wake, REM, and NREM on the one hand, and individual differences in corpus callosum morphology and hemispheric communication as a function of handedness on the other, interact to result in handedness differences in sleep architecture.     

Children’s distributive justice: the role of gender norms in different settings

Children ages 6, 8 and 10 (N = 66) distributed resources to a boy and a girl when the proportion of feminine and masculine resources varied, when the preferences of the boy and the girl varied, and when the setting was public or private. Children used gender norms to sort the resources but they primarily sorted the resources equally, even when it required violating gender norms. When there was an atypical preference, participants provided more atypical resources to the children. However, when the setting was public, they provided fewer atypical resources. Overall the results indicate that gender norms are especially strong in public settings but explicit information about preferences can lead children to be flexible about gender norms.
