Single-question measures of overall job satisfaction: A comment on Quinn,Staines and McCullough

A survey of national sample of workers finds differences in percentages of workers reporting job dissatisfaction as a function of the wording of six questions used to measure overall job satisfaction. These results are compared with a local sample of production workers who answered a job satisfaction questionnaire employing the same six questions. There is a statistically significant difference between the national sample and the local sample. The differences obtained suggest that the employees' work and life situation are at least as influential in changing questionnaire responses as the wording of questions is. Implications for practice are discussed.     

Sex differences in perceptions of familial and occupational roles

Women's lower achievement level in the professions is explained by the Multiple Role Negotiation perspective as resulting from the difficulty in balancing the “active” or demanding roles of wife/mother and a high level professional role. The Value Difference perspective, on the other hand, explains this differential achievement as resulting from differences in degree to which women value professional roles and their familial role, with perceptions of “demand” serving only as “excuses” to mask values. To explore the assumptions of each position three research questions are posed and 33 first-year students in a professional program are surveyed. The findings reveal that neither males nor females perceive the female familial role as the “more active” one; females, however do anticipate less career advancement, value the higher level role less, and also perceive it as a more demanding role than the lower level role.     

Subtyping eating disordered patients along drive for thinness and depression

Subtyping individuals who binge eat by “diet-DT” and “depression” has yielded two valid and clinically useful subtypes that predict eating severity, comorbid psychopathology and outcome. The present study aimed to find four subtypes based on these dimensions and test their validity. Besides, it explored the distribution of eating disorder (ED) diagnoses across subtypes given their known heterogeneity, crossover and binge-eating fluctuation.Cluster analysis grouped 1005 consecutively admitted ED adult women into four subtypes, those previously described “DT” (22%), “DT-depressive” (29%), and “mild DT” (25%) and “depressive-moderate DT” (24%). Overall “mild DT” presented lower and “DT-depressive” greater eating and comorbid psychopathology than the rest, whereas “pure DT” and “depressive-moderate DT” presented no differences on bulimic symptoms but in psychopathology (p < .01). Finally, while BN-P patients were mostly and similarly distributed in the “DT” and “DT-depressive” subtypes than in the other, AN were in the new “mild DT” and “depressive-moderate DT” (p < .01). However, BN-NP, BED and EDNOS were similarly represented across subtypes.Results are discussed with regard to 1) the newly emerged subtypes that may explain cases in which DT prevents or does not predict binge eating; 2) the confluence of DT-depression that signaled greater eating and comorbid pathology, particularly self-control problems; 3) ED-DSM-diagnostic criteria.     

Cognitive development and locus of control as predictors of preschoolers' understanding of safety and prevention

Preschoolers' cognitive level and locus of control orientation and their parents' locus of control orientation were considered as possible predictors of children's abilities to differentiate between safe and unsafe situations (safety score) and specify preventive measures (prevention score). Individual interviews were conducted with 3- to 6-year-old children enrolled at a daycare center, and their parents completed the Rotter Internal-External Locus of Control and the Accident Locus of Control (ALOC) scales. As hypothesized, children's level of causal reasoning was positively correlated with their safety and prevention scores. A curvilinear relationship was evident relationship existed with prevention score. Fathers' ALOC score was the only parent measure that predicted children's safety score, while none of the parent measures were predictive of children's prevention score. The findings were discussed in terms of safety education programs and directions for future research.     

Breakdowns in flexible use of information: Intelligence-related differences in transfer following equivalent learning performance

Groups of retarded and nonretarded children were investigated as they learned three rules underlying problems adapted from the Raven Progressive Matrices Test: rotation, imposition, and subtration. The interest was in evaluating group differences in the ease with which the original set of rules was learned and the flexibility with which these rules were transferred to modified contexts. In the case of either learning or transfer, the metric of performance was the amount of aid, specifically the number of computer-generated graduated hints, needed for each subject to solve the problems. The groups were matched on their entering competence to deal with the rules under scrutiny, and also on mental age. No group differences were obtained as the subjects learned the original set of rules. However, on subsequent occasions when required to make flexible use of those rules, clear group differences emerged; and those differences increased as the similarity of the training and test contexts decreased. The results were seen as consistent with theories that emphasize transfer flexibility as one potential source of individual and comparative differences in intelligence.     

An alternative scaling method for priorities in hierarchical structures

The early contributions of Saaty have spawned a multitude of applications of principal right (PR) eigenvector “scaling” of a dominance matrix [R]. Prior to Saaty's work (1977–1984) scaling of dominance matrices received little attention in multidimensional scaling, e.g., see Shepard (1972, pp. 26–27). This eigenvector method (EM) of scaling [R] yields u_i scores (weights) popularly used at each branching of the Analytic Hierarchy Process (AHP) technique that has been increasingly applied in multiple criterion analysis of utility, preference, probability, and performance. In this paper, it is proposed that an alternate least squares method (LSM) scaling technique yielding least squares optimal scores (weights) provides $\text{w}{}_{\mathrm{i}}{}^1$ values having a number of important advantages over u_i scores popularly utilized to date.     

The different types of limb apraxia errors made by patients with left vs. right hemisphere damage

Limb apraxia errors were compared among normal controls and right- or left-hemisphere-damaged patients as they imitated gestures with the ipsilateral hand. Both brain-damaged groups made similar errors on nonrepresentative and representative/intransitive movements. In contrast for pretended object use movements (transitive), the left-hemisphere-damaged group made more arm position and classical body-part-as-object errors while the right hemisphere group made as many partial errors and more less-primitive, body-part-as-object errors than the left-hemisphere-damaged group. These results help explain why a certain percentage of right-hemisphere-damaged patients are labeled apraxic, but also suggest that the left hemisphere is more important for integrating intrapersonal space and the “representation” of extrapersonal space.
