An olfactory investigation of the compatibility of oddity instructions with the design of a 3-AFC signal detection task

There are two principal differences between the Triangular Method and the 3-Alternative Forced-Choice (3-AFC) procedure originating from the theory of signal detection. These are the instructions given and the types of three-stimulus sets (‘triangles’) presented to the subject.In the Triangular Method the subjects are instructed to select the odd stimulus from each triangle presented, whilst in the 3-AFC task the subject must either select the strongest or identify the weakest stimulus.The triangles presented in the Triangular Method sometimes contain two physically weak stimuli plus one stronger, and at other times two strong stimuli plus one weaker. In contrast, in a 3-AFC experiment all the triangles comprise either two weak plus one stronger, or two strong plus one weaker stimulus.Previous research has shown that the parameter d' is invariant with the two procedures, if the appropriate models are used for conversion of proportions of correct responses into corresponding values of d'.The present experiments provide evidence that the Triangular Method instructions (to select the odd stimulus) used in combination with the 3-AFC task design (using three types of triangles) does not result in biased estimates of d'. In addition, it was shown that even after a large number of presentations the value of d' remained stable, which supports the notion of stability of the decision rule implied by the oddity instructions.     

Predictors of turnover of female factory workers

This study examines predictors of turnover of female factory workers in a multivariate framework. Findings indicate that organizational, job, and personal characteristics are equally important in explaining turnover. Variables significantly related to turnover were tenure, cycle time, peer leadership, communication flow, training time, family income, and satisfaction with pay. The AID technique was demonstrated as a means of identifying interaction effects.     

Sex-role self-concept and attitudes related to occupational daydreams and future fantasies of college women

This study explored the relationship of sex-role self-concept and general attitudes toward women's roles to patterns of career preferences and to career salience among 50 undergraduate women. Sex-role self-concept was measured by the Bem Sex-Role Inventory, and attitudes by the Attitudes Toward Women Scale. Patterns in career preferences were determined by studying the degree of gender dominance in past occupational daydreams as well as in present college major and intended future occupation. Career salience was measured using a content analysis of written future fantasies. Sex-role self-concept was related to past occupational preferences, with masculine-typed women showing a pattern of nontraditional daydreams compared to those of feminine-typed women. Attitude variables were related to present career choices, with liberal women in more male-dominant fields than conservative women. Both self-concept and attitude variables were related to career salience, measured by the proportion of fantasies about the future devoted to work themes. Masculine women showed evidence of more career salience than androgynous or undifferentiated women, and liberal women more than conservative women.     

Volunteerism as an aspect of women's work lives

Results of a mail survey of 292 female volunteers, aged 23–44, indicate that the role of volunteer work may be that of consciously chosen primary work, a supplement to primary work, or a vehicle for entry or return to employment. The three roles are associated with differences in relationship to the labor market, satisfactions sought, nature and amount of volunteer work done, satisfaction, involvement, commitment, and plans for continued membership. The survey instrument incorporated the Organizational Commitment Questionnaire, which was evaluated for its applicability to a volunteer population.     

Relationships between vocational development and self-concept in sixth grade students

Super, in his self-concept theory of vocational development, indicates the existence of a strong relationship between vocational development and the development of self-concept in adolescent and adult subjects. This study was designed to test for this relationship in preadolescent subjects. The study investigated the relationships among a measure of career maturity, self-concept, socioeconomic status, race, sex, place of residence, and age. The research sample included 300 randomly selected sixth grade students enrolled in 22 public schools in the state of Georgia during the fall quarter of 1978. Data were obtained by the administration of two instruments, the Career Maturity Inventory-Attitude Scale (CMI-AS) and the Piers-Harris (P-H) Children's Self-Concept Scale. A multiple regression analysis was utilized to analyze the data. Results of this study indicate a positive but low correlation between the total scores on the CMI-AS and the P-H Scale. All six of the self-concept factors on the P-H Scale were found to be significantly correlated to the CMI-AS score. Socioeconomic status was found to be significantly correlated to the CMI-AS score. Although race was not found to be a significant source of variance on the CMI-AS, the interaction of race and socioeconomic status was found to be significant. Sex, place of residence (urban and rural), and age were not found to be significant sources of variance on the CMI-AS.
