THE LONG-TERM IMPACT OF WOMEN'S STUDIES ON STUDENTS'PERSONAL LIVES AND POLITICAL ACTIVISM

Stake, Roades, Rose, Ellis, and West (1994) reported that women's studies classes led to more feminist activism and greater personal courserelated changes than nonwomen's studies classes. The present study tested the durability of the positive changes observed in women studies students 9 months following the last week of class. Comparisons between students who participated at follow-up (26.3%) and students who did not participate indicated that the follow-up participants were representative of all students who completed the courses. In the follow-up sample, class impact reported in the last week of class was sustained at follow-up. Women's studies students continued to report substantial changes in their interactions with others and willingness to adopt new roles and behaviors. Ratings of positive effects were significantly higher than ratings of negative effects ( p < .0001). Students'responses indicated they were using their women's studies learning as a framework for understanding their experiences and making lifestyle changes.     

FEMINISM AND WOMEN'S FRIENDSHIPS

The ideology of "sisterhood" within the feminist movement suggests that feminists' and nonfeminists' same–sex friendships would differ profoundly. This assumption was tested by examining the friendships of 45 heterosexual nonfeminists, 43 heterosexual feminists, and 38 lesbian feminists from a large midwestern city. Participants ranged in age from 19 to 46. Using objective measures, differences were found between feminists and nonfeminists for some structural dimensions of friendship, including number of cross–generational friendships, degree of equality, and amount of privacy preferred with a best friend. Lesbian feminists preferred more privacy with their friends than nonfeminists, but rated their friends as lower on relationship quality and degree of equality than heterosexual feminists and nonfeminists. The three groups did not differ on the affective content of friendship, including liking, loving, satisfaction and commitment. However, feminists subjectively perceived their feminism as having contributed to both structural and affective changes in their friendships.     

Choosing and refusing: doxastic voluntarism and folk psychology

A standard view in contemporary philosophy is that belief is involuntary, either as a matter of conceptual necessity or as a contingent fact of human psychology. We present seven experiments on patterns in ordinary folk-psychological judgments about belief. The results provide strong evidence that voluntary belief is conceptually possible and, granted minimal charitable assumptions about folk-psychological competence, provide some evidence that voluntary belief is psychologically possible. We also consider two hypotheses in an attempt to understand why many philosophers have been tempted to view belief as involuntary: that belief is a prototype concept and that belief is a dual character concept. Altogether, our findings contribute to longstanding philosophical debates about the relationship between the will and the intellect, while also advancing scientific understanding of important social judgments.     

Forget about the future: effects of thought suppression on memory for imaginary emotional episodes

Whether intentional suppression of an unpleasant or unwanted memory reduces the ability to recall that memory subsequently is a contested issue in contemporary memory research. Building on findings that similar processes are recruited when individuals remember the past and imagine the future, we measured the effects of thought suppression on memory for imagined future scenarios. Thought suppression reduced the ability to recall emotionally negative scenarios, but not those that were emotionally positive. This finding suggests that intentionally avoiding thoughts about emotionally negative episodes may inhibit representations of those memories, progressively reducing their availability to recall.     

Twin Inc.

This paper presents an account of how human spontaneous embryonic chimeras are formed. On the prevalent view in the philosophical literature, it is said that chimeras are the product of two embryos that fuse to form a new third embryo. We call this version of fusion synthesis. In contrast to synthesis, we present an alternative mechanism for chimera formation called incorporation, wherein one embryo incorporates the cells of a second embryo into its body. We argue that the incorporation thesis explains other types of chimera formation, which are better understood, and is more consistent than synthesis with what is known about embryological development. Incorporation also has different implications than synthesis and so avoids the philosophical puzzles that are often said to accompany embryonic chimera formation—puzzles which pose problems to the human embryo’s persistence from fertilization to the fetal stage of human development.     

Treatment Choice and Placebo Expectation Effects

Placebo expectations can have a strong influence on physical and mental health outcomes. In prior research examining placebo expectation effects, participants have been assigned placebo treatments rather than being actively involved in selecting their treatment. In modern health care, however, individuals are often involved in health care decisions. We review relevant literature regarding choice and placebo expectation effects and conclude that exercising choice over a treatment should strengthen placebo effects. Data relevant to this hypothesis is reviewed. Next, we provide a framework for understanding the key variables involved in mediating and moderating the influence of treatment choice on placebo expectation effects. Finally, theoretical and practical issues revolving around treatment choice in the context of placebo effects are raised.     

Dividing attention between color and shape revisited: redundant targets coactivate only when parts of the same perceptual object

When a single perceptual object provides two different reasons for a particular decision (by containing two qualitatively different targets), detailed analyses of the response-time distributions have shown that the two different reasons are jointly responsible for the final decision. The question is whether this coactivation occurs because the two targets contained by the object were from separate dimensions (e.g., color and shape) or were parts of the same perceptual object. Early work argued in favor of dimensions, implying that the types of information being processed is critical, as opposed to their sources; more recent work has argued in favor of objects. Experiment 1 in the present paper corrected for a potential bias in the design of some recent studies and found additional evidence in favor of objects. Two additional experiments directly manipulated whether redundant targets would be perceived as parts of one or two perceptual objects (while holding all else constant) and produced the strongest evidence to date that coactivation requires that the redundant targets be parts of one object. This reverses the original conclusion and suggests that the sources of information are critical, as opposed to the types. Two specific versions of the object-based model are discussed.
