Gender and time variations in medical students' value development

A classic study by Becker and Geer proposed that medical students underwent cycles of value development during medical school. Initially, high levels of humanitarianism declined then re-emerged as students neared graduation. Declines in humanitarianism were accompanied by increased interest in extrinsic rewards. This paper examines value development in medical school for 200 men and women recent graduates. Questionnaire data collected at three times were used to develop scales of students' orientations toward humanitarianism and extrinsic rewards. We find partial verification for value-change patterns described by Becker and Geer, but gender variations are stronger than time variations. Women showed stronger humanitarianism and stronger interest in work conditions at all times than did men. Interest in extrinsic rewards increased for students of both genders but never surpassed humanitarianism in relative importance.The authors appreciate aid in data analysis from Daniel Duross and Tod Sloan and comments on earlier drafts on the paper by Camille Wortman and Roland K. Hawkes. The research was supported partially by a grant from the Spencer Foundation. An earlier version of the paper was presented at the American Sociological Association Meeting in Detroit.     

Dual-career planning,marital satisfaction and job stress among women in dual-career marriages

This study examined the structural relationship between dual-career planning, spouse support, problem-solving effectiveness, interrole conflict, marital satisfaction, and job stress among married female professionals. Dual-career planning and spouse support were found to be negatively associated with interrole conflict and positively associated with problem-solving effectiveness in the marriage. Interrole conflict was found to be positively associated with job stress and negatively asociated with marital satisfaction.     

WHAT CONSTITUTES AN ‘APPROPRIATE PSYCHOLOGY’ FOR THE DEVELOPING WORLD?

The impact of psychology on the developing world has begun to receive some attention, but there is a need for theoretical concepts in order to provide a framework for critical discussion. Using the concepts ‘dual perception’ and ‘parallel growth’ (Moghaddam and Taylor 1985) as a framework, the concept of ‘appropriate psychology’ is introduced to assess the transfer of psychology from the developed to the developing world. Six criteria for evaluating appropriateness are discussed: self-reliance, needs responsiveness, cultural compatability, institutional feasibility, economic suitability and political practicality.     

Choice reaction performance following an error

Some data are presented showing the changes in choice-reaction time (CRT) and the probability of error (PE) on the five trials following an error in a two-choice experiment. The magnitudes of the increase in RT and the decrease in PE are different according as the error-trial stimulus is re-presented or the alternative stimulus is preservec. In addition, RT is quicker to recover its equilibrium value than is PE.This pattern of changes implicates two distinct adjustments to the underlying decision process following an error: (i) a selective outward adjustment of the boundary at which the error was uttered, and (ii) a delay, with respect to presentation of the reaction stimulus, of the epoch at which the subject begins sampling information from the stimulus display. When these ideas are concatenated with the sequential probability-ratio-test model for CRT, a theoretical relation can be derived between the difference in mean RT for an error and for the same response given correctly, on the one hand, and the decrease in PE on the trial following an error, given that the alternate stimulus is presented, on the other. This relation is satisfied by the data.     

An individual differences pure extinction process

A pure extinction process memory retrieval latency model is completely characterized by the number of items to be recalled n and the recall rate λ. In this paper λ is allowed to vary across the population of subjects. Results are given for arbitrary individual differences distributions on λ. When λ is distributed gamma the results are very simple and method of moment estimators are easily obtained. In addition the shape parameter of the gamma individual differences distribution turns out to be an index of the degree of heterogeneity of the recall parameter. The pure extinction process model is also appropriate for certain collection and detection tasks.     

Instructions, illusory self-tilt and the rod-and-frame test

If an illusion of self-tilt is involved in rod-and-frame test performance, then instructions to adjust the rod to the body midline (egocentric instructions) should result in less rod adjustment error than the standard instructions for the rod-and-frame test to adjust the rod to the gravitational vertical. Two experiments were designed to examine this possibility. The results of the first experiment indicate that the tilted rod-and-frame display induces an illusion of self-tilt in the opposite direction. Significant differences between instructional conditions were found in the second experiment as expected. Other rod-and-frame studies are discussed in view of these findings.     

Shiftwork: A record study approach

The use of employer records to assess shiftwork effects is discussed. Methods for gaining access to records are covered, along with some of the problems involved in evaluating the data. Five general sources of data are described.     

The work of worrying in children undergoing surgery

This study examined the relationship involving children's level of anxiety, defensiveness, and play patterns 1 week prior to, during, and 1 week after hospitalization for minor surgery. A 7-month follow up was also conducted in order to assess the children's recall for hospital events and coping style. The results suggested that two classes of children could be identified. The children in one group distinguished themselves in terms of their disposition to engage in the work of worrying (i.e., were low defensive prior to hospitalization, actively played with stress-related toys prior to hospitalization, and reported minimal distress and anxiety following surgery). Those in the second group were highly defensive, avoided playing with stress-related toys, and reported most anxiety following surgery. The parallel between children and adult patterns of dealing with surgery was considered in terms of Janis's (1958) model of coping with psychological stress.This research was supported by a grant from Canada Council, Grant No. S72-2314-52.

The effect of reinforcement and verbal rehearsal on selective attention in learning-disabled children

A central-incidental task of selective attention was administered to 100 learning-disabled boys — 48 younger children (81/2–101/2 years) and 52 older children (101/2–121/2 years). Subjects at both age levels were assigned to one of four conditions: (a) a standard condition; (b) a rehearsal condition, in which subjects were taught a verbal rehearsal strategy; (c) a reinforcement condition, in which correct responses were rewarded; and (d) a combined rehearsal-reinforcement condition. Older subjects recalled more central task but not more incidental task information than younger subjects. A measure of selective attention efficiency was also greater for older than for younger subjects. Central recall in the rehearsal-reinforcement condition was greater than in any other condition. Central recall was greater in the rehearsal condition than in the standard and reinforcement conditions. Selective attention efficiency was greater for both rehearsal conditions than for both nonrehearsal conditions. Incidental recall was higher for reinforcement subjects than for rehearsal subjects. Results suggest that induced verbal rehearsal improves central recall and selective attention in learning-disabled children. Reinforcement alone does not improve central recall but may when paired with rehearsal.This article is based on a Ph.D. dissertation completed by the senior author at the University of Virginia.

Contribution of the speech musculature to apparent human EEG asymmetries prior to vocalization

Vocalizations are preceded by slow EEG waves over inferior frontal scalp regions, but some controversy exists as to whether these slow potentials are left-lateralized as a function of speech. In this study both speech and non-speech vocalizations were studied, under conditions of repetitive and variable production. Averaged responses over the speech musculature, including the temporalis, masseter, orbicularis oris, and mylohyoid muscles, as well as the eyes and tongue, were calculated simultaneously with scalp EEG averages. The responses of the temporalis and masseter muscles, as well as that of the tongue, were correlated with EEG sites at specific latencies prior to speech, suggesting that no part of the inferior frontal EEG record was free from myogenic confounds. In addition, all significant EEG differences between speech and non-speech conditions were subsequently eliminated by covariance analysis, using selected muscle channels as covariates. Previous reports of asymmetrical “speech potentials” in the EEG probably reflected a combination of several myogenic confounds.
