A reexamination of sex differences in job preferences

Previous research has found conflicting answers to the question of whether males and females share similar preferences for various job characteristics. It is difficult to determine if the different findings are due to the different populations sampled, the various methodologies employed, or to a real change in the phenomenon itself. This study essentially replicates earlier work by having 130 male and 84 female college students rate the importance of 10 job characteristics for both themselves and members of the opposite sex. Both sexes rated motivators as important, but females also placed importance on the hygienes. Males tended to underestimate the importance of the motivators for females, while females overestimated the importance of hygienes for males. The subject's sex could be predicted by both the importance for self and importance for opposite sex ratings, contrary to the earlier study. The difference in results and interpretation was shown to be due to the type of analyses used. Additionally, it was found that females' job preferences were related to their mothers' educational achievement.     

The measurement of sleep onset latency in insomnia

Research into insomnia has relied almost exclusively upon subjects self-reports of sleep onset latency. The unreliability of self-reports have been repeatedly criticized yet despite the implementation of suggested changes substantial weaknesses remain. This study of 17 insomniacs outlines the development of a simple electrochemical device designed to yield objective estimates of sleep onset latency and compares this with independent estimates made by patients and their partners. The application of this device and the implications for the continued use of self-report measures are discussed.     

A chronometric study of sentence processing in deaf children

It has been consistently reported the deaf children have tremendous problems in reading English sentences. Three experiments were conducted in the present study to investigate the nature of deaf children's reading inability. The first experiment looked into the letter-decoding process. It was found that deaf subjects took longer than normal-hearing subjects in encoding and decoding alphabetic letters. The second experiment employed a sentence-picture verification paradigm. The results showed that deaf subjects adopted a visual-imagery coding strategy rather than a general linguistic coding strategy as described by H. H. Clark and W. Chase (Cognitive Psychology, 1972, 3, 472–517) and by P. A. Carpenter and M. A. Just (Memory and Cognition, 1975, 3, 465–473). However, when the sentence was presented in manual signs (Experiment 3), deaf subjects' verification time showed that they adopted a general linguistic coding strategy. Thus, deaf subjects are capable of linguistic coding strategy, but they do not apply it to process printed English sentences. A second-language hypothesis was advanced to account for the obtained data. Deaf children's reading inability was also discussed from this perspective.     

Formal assessment of problem-solving and planning processes in preschool children

While much is known about adult problem-solving, the materials, analyses, and theoretical issues from the adult literature rarely make contact with the tasks typically used to investigate children's thinking. This paper examines the behavior of 4-, 5-, and 6-year-old children attempting to solve a novel variant of the Tower of Hanoi task. Problems varied in difficulty (one to seven moves for the minimum path solution) and in goal type: tower (all objects on one peg) or flat (all pegs occupied). For each problem, children gave verbal statements of their complete solution plan. The Plan Analysis examined performance as a function of goal type and age. Better performance was observed for tower ending problems, and among older children. The Error Analysis revealed that specific error propensities were related to both age and goal type. The Strategic Analysis compared the first move profiles of 6-year-olds to those of several plausible move selection models, and a high degree of correspondence was obtained between specific models and individual children. Young children appear to have rudimentary forms of many of the problem-solving processes previously identified in adults, but they may differ in encoding and representational processes.     

Orientation in cognitive maps

In 14 experiments, subjects had to “point to” surrounding environmental locations (targets) while imagining themselves in a particular spot facing in various directions (orientations). The spatial information was either committed to memory (cognitive maps) or directly presented on each trial in the visual or tactile modality. Reaction times (RT) indicated that orientation shifts were achieved through mental rotation in the visual task, but not in the cognitive map or tactile tasks. Further, in the latter two tasks targets were located most quickly when they were adjacent to or opposite the imagined orientation. Several explanations of this finding were tested. Various aspects of the data suggest that cognitive maps are not strictly holistic, but consist of orientation-specific representations, and—at least in part—of relational propositions specific to object pairs.     

Measurement of sexual arousal in several paraphilias: The effects of stimulus modality,instructional set and stimulus content on the objective

The effects of instructional set (become aroused or suppress arousal), stimulus modality (videotape, audiotape, slides, free fantasy) and stimulus content (paraphilic or non-paraphilic) on sexual arousal, as measured by penile plethysmograph, of six different groups of paraphilics, pedophiles, rapists, exhibitionists, homosexuals, sado-masochists and fetishists, were determined. The results showed significant main effects of instructional set and of stimulus modality (videotape was clearly more arousing) as well as several complex interactions of diagnostic group with the other independent variables.     

An Assessment of the Effectiveness of Two Tactics to Reduce Arousal in Crowded Mass Transit Settings1

Studies of crowding in various settings have shown that individuals are aroused and frequently suffer from ill health. Several studies have shown that it is possible to successfully intervene in residential, shopping, and classroom settings to reduce the negative effects of crowding. The present laboratory experiment assessed the effectiveness of two tactics commonly used by passengers in crowded mass transit settings. Results indicated that the two tactics, reading a newspaper or talking to others, failed to reduce arousal. An explanation for the failure of these tactics is offered.
