Decreases in simple reaction time as a function of stutterers'' participation in a behavioral therapy

Stutterers and fluent speakers were compared on a simple reastion time task to determine whether participation in a behaviorally based stuttering program had an effect on clients' reaction time scores. A group of fluent speakers was used to control the possibility that any changes in reaction time latency were due to practice or familiarity with the task. All participants responded with a finger-lift as quickly as possible to 25 visual stimuli presented by computer. Response latencies from the stutterers and the fluent speakers were compared. Stutterers' posttherapy reaction time latencies were significantly shorter than their pretherapy latencies. It was also observed that stutterers' reaction time scores prior to therapy did not differ significantly from fluent speakers' scores. However, stutterers' posttherapy reaction time scores did differ significantly from fluent speakers' posttest scores. The results are discussed in terms of arousal, motivation, familiarity with the environment, conditioned inhibition, and two aspects of therapy.     

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.     

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.     

Evaluating associations between maternal social support and cognitive development for infants in poverty

Infant cognitive development may be associated with maternal social support, although these relations have not been well-examined for infants living in poverty. We explore whether maternal social support is associated with cognitive development for 113 infants living in poverty. Infant cognition was measured at age 9–12 months using the Bayley Scales of Infant and Toddler Development 3rd edition. Mothers provided information regarding perceived social support received from fathers, family, friends, and community members. Controls included maternal race and infant sex. Linear regression revealed no significant relationships between maternal social support and infant cognition in this sample.     

Investigating the validity of the Perceptual Awareness Scale – The effect of task-related difficulty on subjective rating

The Perceptual Awareness Scale (PAS) is often used to probe conscious experience, but the assumptions behind the scale and its validity are rarely tested. Using a continuous colour estimation task to assess perceptual quality, we focus on how well PAS follows perceptual quality and how the presence of the estimation task affects PAS ratings. We varied the number and presentation time of stimuli in a simultaneous presentation and target position in a sequential presentation. In all experiments, PAS rating closely followed colour precision. However, it was affected by task-induced response bias, even when the possible task difficulty was judged, without performing the task itself. Still, this bias was only observed on the absolute rating level rather than the scale's ability to capture changes in perceptual quality. Reported studies shed light on factors influencing scales outside of the scale formulation and construction.     

Exploring the factor structure of the Francis Psychological Type Scales among a sample of Anglican clergy in England

ABSTRACT

The Francis Psychological Type Scales (FPTS) were designed to provide a fresh conceptualisation and operationalisation of psychological type theory suitable for application within self-report quantitative studies in the individual differences tradition. The present study tests the factor structure of this instrument among a sample of 722 Anglican clergy. The Varimax Rotated Solution with Kaiser Normalisation recovered the hypothesised location of 74 of the 80 items across four factors with factor weightings of or above .38. The FPTS are commended for use.     

Validation of the German version of the Driver Skill Inventory (DSI) and the Driver Social Desirability Scales (DSDS)

The psychometric properties of the new German versions of the Driver Skill Inventory (DSI) and the Driver Social Desirability Scales (DSDS) were examined. The DSI is a self-report measure assessing perceptual-motor skills and the safety motive as two important aspects of driving behavior. Self-report measures, however, are susceptible to socially desirable responding (SDR) which is why both general and specific driving-related SDR scales have been developed: Based on the Balanced Inventory of Desirable Responding (BIDR), the DSDS taps Driver Impression Management and Driver Self-Deception as two important aspects of SDR. In two validation studies with less experienced (N = 130) and experienced drivers (N = 1199), both inventories showed the expected two-factor structure and satisfactory internal consistency. In Study 1, self-ratings were compared with and confirmed by peer-ratings. In both studies, we accumulated evidence of convergent and discriminant validity for the German version of the DSI by correlating it with demographic, driving-specific, and personality measures, including the Big Five, Type A behavior, and sensation seeking. The DSI seemed to be only marginally contaminated by SDR.
