Analysing user’s reactions in advice-giving dialogues with a socially intelligent ECA

In this paper, we investigate the user’s reactions to received suggestion by an Embodied Conversational Agent playing the role of artificial therapist in the healthy eating domain. Specifically, we analyse the behaviour of people who voluntarily requested to receive information from the agent, and we compare it with the results of a previous evaluation experiment in which subjects were not properly motivated to interact with the agent because they were selected for evaluating the system. This study is part of an ongoing research aimed at developing an intelligent virtual agent that applies natural argumentation techniques to persuade the users to improve their eating habits.     

Gender differences in enrollment in computer camps and classes

Informal reports suggest that computer literacy (computer awareness and programming skills) is sought more often by boys than girls. In order to gather more systematic data on this possibility, questionnaires were sent in the summer of 1982 to directors of summer camps and classes that offered training in programming for microcomputers. Twenty-three directors of summer programs, serving a total of 5,533 students, provided data on enrollment, type of sponsorship of programs (private, public schools, universities), level of difficulty of programming classes, cost, and residential versus day use. Three times as many boys as girls were enrolled in the total sample. The ratio of males to females increased with grade, cost of program, and level of difficulty of course offerings. Possible explanations for differences in enrollment are discussed.     

NYBORG'S ANALYTICAL ROD-AND-FRAME SCORING SYSTEM: A COMPARATIVE STUDY IN ZIMBABWE*

Witkin's method of scoring the Rod-and-Frame Test (RFT), most generally used, has been criticized by Nyborg. On the basis of studies with Danish students he provided evidence that RFT performance is multi-determined, and devised a new scoring method to take this into account. The present study, conducted in Zimbabwe, replicated and extended Nyborg's work. The RFT scores of 80 subjects differing in ethnicity, sex and type of course were analyzed employing both Witkin's and Nyborg's methods. Our results confirm Nyborg's finding that factors other than frame dependence are involved in RFT performance, as indicated by differences in response patterns as a function of ethnic group, sex and type of course. It is suggested that Nyborg's scoring method is a valuable tool for the purpose of clarifying the nature and sources of cultural differences in RFT performance.     

Perceived and Actual Discrimination in the Salaries of Male and Female Managers1

This study uses a sample of over 1000 MBA graduates from a Middle Atlantic University to test for sex differences in perceived discrimination and for the actual effects of various physical characteristics and background factors on the starting salaries and later (1983) salaries of these men and women managers. Women more often reported experiencing discrimination, and they typically identified this as general discrimination against women. Fewer men perceived any discrimination. Those men who did claimed to be the victims of affirmative action programs favoring women and blacks over them. Salary data indicated that women did earn less than men, even when controlling for work experience. Evidence for other forms of discrimination was also found. Controlling for prior work experience and year of first professional employment, age and height had a positive effect on men's starting salaries and being overweight, a negative effect. For women, starting salaries were significantly and positively affected by social class. For 1983 income, taller, non-overweight, and older men earned more, as did those who grew up in a higher social class. For women, a positive salary correlate was again being from a higher social class. Areas for future research are discussed.     

The relationship of computer self-efficacy expectations to computer interest and course enrollment in college

Gender differences in perceived self-efficacy for computer use may help account for differential computer interest and course enrollment at the college level. Three hundred sixty-eight students completed a two-page questionnaire assessing perceived computer self-efficacy, plans to take a computer science course, perceived importance of computing skills, and interest in learning about computers. Men rated themselves higher than did women for perceived self-efficacy. They were also more positive on the cognitive outcome measures, but with computer self-efficacy held constant, the magnitude of these differences was decreased, suggesting that perceived self-efficacy may be an important consideration when examining gender differences in computer interest and use.The author wishes to thank Dr. Martin Ford and Dr. Albert Bandura for their helpful comments on an earlier version of this article.

Portions of this research were reported at the annual meetings of the American Educational Research Association in San Francisco, April 1986.     

Attributions of success and failure for actors and observers

Causal attributions of a person actually experiencing a success or failure (the actor) and someone who read about the situation (the observer) were compared. Results supported Jones and Nisbett (1971). Actors were relatively more likely to perceive their outcomes as caused by external factors (task difficulty), while observers attributed these outcomes more to internal factors (effort). Attributions for both actors and observers were also strongly affected by whether the outcome was a success or failure. Hypotheses concerning sex differences in attributions were not supported.     

The role of awareness in human conditioning

The cognitive view of human classical conditioning is that Ss are active in thinking about the pattern of stimulus events which occurs, the demands of the situation, and the kind of responses which they give. A question crucially central to conditioning theory is whether these thoughts and expectations determine conditional responding. This paper reports on two conditioning and personality experiments, employing the standard procedure of a single cue CS-UCS schedule and masking task, which assess awareness of stimulus contingencies and demand characteristics by means of a postexperimental questionnaire. Results were quite clear in showing no significant relationship between measures of awareness and eyelid conditioning.
