In much research in social psychology it is impractical to get quantitative measure of the degree of effectiveness of certain social behaviors, yet associates can sense that effectiveness sufficiently well to detect those who manifest the behavior in very high or in very low degree. This paper develops a technique of biserial correlation from wide-spread classes to deal statistically with such situations, develops standard error formulas for it, and points to a wide range of usefulness for this type of technique.  相似文献

Why is the computer more alluring to boys than it is to girls? One answer to this question is drawn from a social psychological model of human interaction. Social psychological research indicates that the expectations an individual has about another person can shape his or her interaction with that person. We hypothesized that, in a similar manner, the expectations software designers hold about the users of the software they design are central in determining the way the software they design interacts with the user. In order to test this notion, we had 43 educators with programming experience design software for either boys, girls, or students, and found that programs for girls were classifiable as “learning tools,” whereas programs for both boys and students were most like “games.” These differences occur as a function of the designers' expectations of the characteristics of potential users of the program and result in sex stereotyped software. We conclude that it is not the computer, or even the software, that is at the root of the sex bias in software, but the expectations and stereotypes of the designers of the software.  相似文献

This study examines the roles of life stress, hassles, and self-efficacy in the prediction of adjustment in aging. Twenty-six men and 26 women between the ages of 65 and 75 participated in an initial structured interview and a follow-up interview one year later. Measures of negative life change events, daily hassles, and self-efficacy were used to predict depression, psychosomatic symptoms, and negative well-being both in concurrent and time-lag designs. Frequency of hassles was the strongest predictor, showing significant relationships with depression and psychosomatic symptoms both concurrently and one year later, even when initial distress was controlled. Perceived self-efficacy was also shown to be predictive of current and subsequent depression, even after initial depression was controlled. Frequency of negative life events was a weak predictive factor. The only area where life events related significantly to health was in time-lag analyses with negative well-being, even when initial distress was controlled.  相似文献

Evidence suggests that teachers treat students differently according to various characteristics, including demographic factors and academic labels. An attempt was made to discover whether teachers' recommendations of punishment would differ according to the students' age, race, gender, IQ level, and type of offense. Punishment was recommended for a hypothetical student in a fighting, a stealing, and a cheating situation. The results revealed that southern white female teachers generally reported that they would recommend more severe punishment for males than for females and for white males than for black males. It was noted that these results occured despite the fact that teachers differed in age, number of years of teaching experience, grade levels taught, and education level.  相似文献
