Age,and midcareer crisis: An empirical study of academics

This study develops an empirical basis for examining the midcareer crisis/ transition period of academic staff surveyed by questionnaire in four Australian Universities and Colleges. A total of 672 usable returns were obtained, representing a response rate of 52% of the academic staff. Principal components and factor analysis were used to establish latent social-role variables. Analysis of variance and covariance was applied using the latent social-role variables as dependent variables and occupational attributes such as age, sex, etc., as independent variables. The variable age was isolated from the larger study in this paper to illustrate empirically a midcareer crisis period for the population studied which is consistent with the general literature on midcareer crisis/transition.     

Socially mediated fear reduction in rodents: Distraction,communication, or mere presence?

Two studies investigated why the presence of conspecifics reduces open-field fear. In Experiment 1 rats paired with another experimentally naive rat were not less fearful than alone controls. However, rats paired with a partner who had been preexposed to the open field exhibited fewer fear responses than alone controls. Since preexposed companions appeared to initiate more social interactions than nonpreexposed companions, it was argued that the preexposure effect could be the result of preexposed companions distracting actor rats from threatening stimuli. Experiment 2 tested this explanation by pairing socially sated or socially deprived rats with a socially sated or socially deprived companion. In accord with a distraction hypothesis, pairing two socially deprived rats produced the greatest fear reduction effects and also led to more social interaction than pairing socially sated rats. Alternative explanations involving conditioning and communication are discussed.     

Cluster analysis in school psychology: An example

This investigation demonstrates the use of Ward's method of cluster analysis to uncover the underlying classification structure in a group of children (N = 200) referred for psychological evaluations by their public school teachers. Data were acquired on children's intellectual development, academic achievement, and social adjustment. The cluster solution identifies six groups of children which are statistically distinct. All three measurement areas are important in distinguishing among the different groups. The six-group solution accounted for appreciable amounts (95%) of the variability in the three measurement areas. Implications for psychologists working in the schools are discussed.     

Development in moral judgment as indicated by rejection of lower-stage statements

Previous failures of preference rating scales to identify developmental differences in moral judgment may have occurred because the focus was on acceptance of high-stage reasons rather than on consistent rejection of lower-stage reasons. Attention focused on seventh-, ninth-, and eleventh-grade students' (N = 178) rejection of the lower-stage statements that they presumably comprehend but have to varying degrees dropped from their spontaneous-production repertoire. Students rated the adequacy of the reasons presented in statements written to exemplify Kohlberg's stages 1, 2, 3, 4, and 5. Ratings of Stage 1, 2, 3, and 4 statements showed clear age discrimination (all p's < .001). As in previous preference studies, higher-stage items produced no significant age differences. Implications for evaluation of change studies were noted.     

Saccade latency in children and adults: Effects of warning interval and target eccentricity

Saccadic response latency to the onset of an eccentric target was studied in children (mean age = 8.7) and adults. The independent variables investigated were fixation-light offset to target-light onset warning interval (0, 100, 300, and 600 msec) and target eccentricity (5° or 15°). Both children and adults showed shorter saccade latencies under warning-interval conditions. Children were found to have longer latencies than adults with 0 or 100 msec warning intervals but to respond with as short or shorter latencies with 300 or 600 msec warning intervals. Target eccentricity effects did not interact with age, and occurred only with a lower target intensity. Children defined as poor readers could initiate a response as quickly as good readers but were less able to maintain fixation-light fixation prior to target onset.
