Vocational interests of career and homemaker oriented women

Women who had completed the SVIB-W as freshmen in college were contacted 13 to 21 years later and were classified as career (N = 236) or homemaker (N = 527) oriented on the basis of their actual work experiences. Significant differences between the groups were found on 25 of the 44 occupational scales, one of the three nonoccupational scales, and four of the 19 basic interest scales. The interests of the homemaker oriented women were more similar to the interests of women in business, nonprofessional, and home economics occupations while the interests of the career oriented women were more similar to the interests of women in the verbal-linguistic, verbal scientific, and scientific occupations. The results are discussed in terms of previous research and Holland's Occupational Classification system.     

Self-punitive behavior with changing percentages of reinforcement: The proper role of discrimination

Past research on self-punitive behavior has been interpreted as supporting a theoretical éxplanation based on a vicious circle rather than a discrimination hypothesis. Using rats, Melvin (1964) found that self-punitive behavior is not reduced when discrimination is aided by changing the percentage of shock trials from acquisition to extinction. This past research is inconclusive because it is based on a misinterpretation of what is the critical discrimination for extinction, namely the new response-punishment contingency. Using humans, the present study provides evidence that subjects can and do discriminate the change in percentage, but continue to show self-punitive behavior until they make the discrimination that responding results in shock rather than escape.
