Construction and validation of a physician career development inventory

The development and psychometric characteristics of the Medical Career Development Inventory (MCDI) are described. The MCDI represents the initial construction of a career maturity measure for a homogeneous population of adults who encounter a common set of vocational development tasks. The inventory is intended to measure both degree of vocational development and readiness to cope with the developmental tasks encountered in a physician's career. The MCDI includes 35 items that address coping behaviors germane to dealing with the vocational tasks constituting the career development continuum of physicians. Initial evaluation of the MCDI's psychometric properties with a sample of 160 student-physicians supported the content validity of the items, construct validity of the scales, and criterion validity of the inventory.     

Men in female-dominated professions: Distinguishing personality and background features

Personality and background features of men in female-dominated professions were assessed by comparing survey data on 54 men employed in atypical professions (A′s) with 63 men employed in sex-typical fields (S′s). Subjects were American born, college-educated males, under 50 years of age, employed in fields with over 75% male or female participation, and recruited in Atlanta in 1978. Subjects completed a biographical questionnaire, the Cattell 16 PF, and the Bem Sex Role Inventory under three instructional sets. In comparison with S′s the A′s showed lower adherence to traditional sex-role expectations on the Bem Sex Role Inventory, in the allotment of sex-typed household responsibilities, and in their greater “tender-minded” emotional sensitivity on the Cattell 16 PF. In terms of their personal histories, A′s more frequently reported having had employed mothers, having had distant relationships with their fathers, and having been positively influenced in their career choices by women. A′s more frequently experienced a death of a parent or sibling, or parental divorce or separation, and frequently mentioned such stresses as sensitizing them to their nurturant and emotional capabilities. There was also evidence that upward-mobility strivings may have contributed to atypical career choice, with A′s more frequently being members of racial minorities and/or of lower socioeconomic background. As expected, in contrast to S′s, A′s shared personality and socialization factors indicative of lower sex-typing, thus confirming the psychological significance of the sex composition of one's occupation for men as was confirmed earlier for women.     

Individual differences in imagery vividness and voluntary heart rate control

Dispositional differences in imagery vividness may account partially for the large individual differences in learning heart rate control. Based upon scores on the Betts QMI Vividness of Imagery Scale, 10 subjects were defined as a high imagery group and 10 subjects were defined as a low imagery group. All subjects were instructed to try to alter their heart rate as indicated by appropriately labeled lights. Six increasing, six decreasing and six rest, 45-sec trials were presented. During the trials, visual heart rate feedback was provided by a digital voltmeter. The dependent measure was computed by subtracting the mean of the last 5 beats of a 15-sec intertrial interval from the mean rate per trial. Results indicated that subjects were able to significantly raise and lower heart rate relative to rest trials. Furthermore, high imagery subjects demonstrated significantly larger changes than low imagery subjects on increase trials but not on decrease trials. Subjects in both groups typically reported using more specific images for increasing heart rate than for decreasing heart rate. These data suggest that dispositional differences in imagery vividness may have contributed to the differential performance of the two groups during the increase task.     

Holland's theory and college-degreed working black and white women

The main concern of this study was to investigate differences between black and white women employed in traditional male occupations who took the Vocational Preference Inventory (VPI) and the Self-Directed Search (SDS). The VPI and the SDS were administered to 155 black and white college-degreed workers in three occupations (engineering, medicine, and law) corresponding to three of Holland's environmental categories (Realistic Investigative, and Enterprising). In general, the findings for the three VPI and SDS scales for these occupational groups indicate that white women when compared to black women in the same occupation tend to report similar mean raw scores.     

Reaction times of severe Broca's aphasics to monaural verbal stimuli

Reaction times of nine subjects with severe Broca's aphasia were measured to verbal stimuli presented monaurally to their left or right ears. The aphasic subjects showed left-ear advantages in reaction times to verbal stimuli, paralleling dichotic findings among aphasic patients. The results are interpreted as consistent with right-hemisphere language processing.     

The multiple roles of Broca's discovery in the development of the modern neurosciences

Using the classical clinico-anatomical correlation method of the French clinical school, Paul Broca confirmed the localization of "language" in the frontal lobe. He actually discovered the lateralization of language in the left hemisphere. These contributions eventually led to the demise of the older concept of the "sensorium commune," because Broca's ideas implied the presence of motor functions in the hemispheres. Although Broca worked within the theoretical motif of the "faculty" psychology, the reflex-oriented "associationist" psychology soon became the predominant theoretical framework of localization, because it accommodated the motor aspect of hemispheric function. Since Broca's time, the study of the biology of language has proceeded along two parallel but sometimes separate lines in the experimental and clinical traditions.
