Effects of consent form information on self-disclosure

When researchers encounter preexisting psychological distress in participants, ethical codes provide little guidance on how to balance issues of beneficence and autonomy. Although researchers may inform participants what will occur given responses indicating distress, this information may lead to biased self-reports. This important issue was addressed in this study by manipulating consent form information regarding the type of psychopathology to be assessed and various levels of possible follow-up. In comparing responses on self-report measures of anxiety, depression, and general psychological distress, men who believed depression was the focus of the study reported fewer symptoms of depression and less trait anxiety as intrusiveness of experimenter follow-up increased. These results are discussed within the framework of socialization theory. Given that half of the sample did not correctly answer questions regarding information contained in the consent form, guidelines to improve consent form comprehension are offered.     

Knowing not

Ontario Institute for Studies in Education, 252 Bloor Street, Toronto, Ontario, Canada M5S 1V6 People often know rapidly and reliably that they do not know something. A review of contemporary theory reveals that the issue has not received much attention; moreover, the accounts available assume that recognition that one does not know something is achieved only by failure to establish that one does know it. A reaction time experiment assessed two aspects of knowing not, by asking people whether they knew common nouns well enough to use them in sentences and whether they had visited certain cities. The findings were that affirmations of negation were often more rapid than positive reports; hence, the account of knowing not as the complement of knowing that something is the case is not necessarily correct. We suggest that knowing not may be attained as rapidly as positive knowledge on the basis of ability to carry out analytical procedures.     

Attitudes toward women among female college students

Female college students' attitudes toward women were investigated to determine the effects of housing, class status, and general field of study, and to provide standardization and reliability data for the AWS scale. Spence and Helmreich's Attitudes Toward Women Scale was administered to a large sample of female college students in a coed, moderately sized, private, Eastern secular college. Results indicated that seniors tend to hold more liberal attitudes toward women than underclasswomen and students in Business and Education tend to hold more conservative attitudes toward women. Interaction effects were observed and reported. Type of housing was not related to attitudes toward women. The split-half reliability technique revealed a strong internal reliability of .92 for the AWS.     

Conditioned suppression in the gerbil

The present report describes apparatus and procedures for investigating conditioned suppression of a running response in the gerbil. Data are presented which demonstrate that the conditioned suppression observed in this situation is not an artifact of alpha responses, pseudoconditioning, or sensitization. An analysis of differential conditioning indicated that cue similarity and US intensity are negatively related to cue-specific differential responding.     

A note on responses to ethyl alcohol before and after smoking1

Differential sensitivity was measured before and after smoking a cigarette by 10 smokers, using 10 nonsmokers as controls. Stimuli consisted of reagent grade ethanol in eight concentrations ranging from 4% to 12%. No significant differences were observed between smokers and nonsmokers or before vs after smoking, although slightly higher overall correct responses and correspondingly smaller jnds were obtained for the nonsmokers. No practice affects were noted among the control group between the first and second set of samples. The findings confirm previous results which had been recently questioned.
