Establishing the Duration of Crimes: An Individual Differences and Eye‐Tracking Investigation into Time Estimation

The time available for viewing a perpetrator at a crime scene predicts successful person recognition in subsequent identity line‐ups. This time is usually unknown and must be derived from eyewitnesses' duration estimates. This study therefore compared the estimates that different individuals provide for crimes. We then attempted to determine the accuracy of these durations by measuring observers' general time estimation ability with a set of estimator videos. Observers differed greatly in their ability to estimate time, but individual duration estimates correlated strongly for crime and estimator materials. This indicates that it might be possible to infer unknown durations of events, such as criminal incidents, from a person's ability to estimate known durations. We also measured observers' eye movements to a perpetrator during crimes. Only fixations on a perpetrator's face related to eyewitness accuracy, but these fixations did not correlate with exposure estimates for this person. The implications of these findings are discussed.

Does Mother Know Best? An Actor–Partner Model of College‐Age Women's Human Papillomavirus Vaccination Behavior

This study examined the associations of perceived threat, perceived efficacy, and parent–child communication with the extent to which college‐age women received the human papillomavirus (HPV) vaccine. Daughters and their mothers completed a survey about the HPV vaccine (N = 182 dyads). The results showed that mothers' perceived self‐efficacy to talk to their daughters and mothers' response efficacy of the vaccine were indirectly related to mother–daughter communication about HPV. Further, mother–daughter communication mediated the relation between mothers' intention to talk to their daughters and daughters' HPV vaccination behavior. This study demonstrates the importance of the social context of health behavior and the role of communication in understanding maternal influence on the HPV vaccination behavior of young adult women.     

Perceptual learning in pigeons: Decreased ability to Discriminate samples mapped onto the same comparison in many-to-one matching

Humans often treat two stimuli that are associated with a common response as similar in other contexts. They do so presumably because those stimuli become conceptually or perceptually more similar to each other (perceptual learning). An analogous phenomenon may occur in pigeons when they are trained with a matching-to-sample procedure in which more than one sample is mapped onto the same comparison. In the present research, pigeons were trained to select one comparison following either of two samples (S₁ or S₂) and to select the other comparison following either of two different samples (S₃ or S₄). When the samples were then presented as positive and negative stimuli in a simple successive discrimination, samples that had been associated with the same comparison during original training (e.g., S₁ vs. S₂) were more difficult to discriminate than were samples that had been associated with different comparisons (e.g., S₁ vs. S₃). Thus, it appears that perceptual learning occurs in pigeons as well.     

Inhibition of return at multiple locations and its impact on visual search

Previous research has shown that when attention is directed sequentially to multiple locations, inhibition of return (IOR) can be observed at each location, with a larger magnitude of IOR at the more recently attended locations. In the present study we asked whether this “multiple IOR” effect influences search only for simple feature targets, as has been shown in the past, or whether it generalizes to more complex, attentionally demanding conjunction search situations. The results demonstrated that IOR effects (1) occur for more complex conjunction search environments, (2) are larger for the attentionally demanding conjunction search, and (3) occur at more locations for conjunction search than feature search. Together these data provide a clear demonstration of the robustness and responsiveness of the IOR effect across search situations—which is precisely what is expected of a phenomenon posited to facilitate efficient visual search of real-world environments. Nevertheless, these data do not firmly establish that IOR effects established by the cueing paradigm before search is implemented are the same as the IOR effects that are assumed to be established during search itself. We suggest that this disconnection between paradigms highlights a fundamental limitation of laboratory-based research.     

Leadership Development of Women Preparing for Ministry

This mixed-methods study investigates the leadership development and leadership skills of women graduate students at a theological seminary. Through the Student Leadership Practices Inventory (Student LPI) and Leadership Competency Inventory (LCI), demographic questionnaire, and focus group interviews, the researchers explored the leadership training the women had received and their perception of their leadership abilities and development needs. The findings showed that the women reported frequently demonstrated exemplary leadership practices and many possessed significant leadership experience. Participants scored highest on competencies utilizing people skills and lowest in areas reflecting competence in cognitive or strategic skills. While exposed to formal leadership education they reported receiving their leadership education primarily through observation and experience.     

Does “Making a Difference” Still Make a Difference?: A Textbook Author’s Reflections

Drawing on my experiences with teaching Psychology of Women and writing three editions of a textbook across two decades starting in 1990, I reflect on the core feminist call to make the personal political. By tracing the chronology and interplay of my textbook writing with my teaching, research, and editing, I speculate about an apparent disconnection between my experiences and research with students (who embrace the feminist call to make a difference) and the textbook market to veer toward less women-centeredness and activism in the pursuit of gender studies. I make my case that the activist goal of making a difference continues to make a difference in individual women’s lives, in women’s relationships, and in a social justice agenda.     

The Effect of Nonverbal Behaviors Associated With Sexual Harassment Proclivity on Women's Performance

We explored whether exposure to nonverbal behaviors that mirror those used by men with sexual harassment proclivity (i.e., high dominance and/or high sociosexual nonverbal behaviors) leads women to perceive those men as potential sexual harassers and lowers women's actual performance on the job. In our first experiment, women's performance was negatively affected when they interacted with a task administrator enacting dominant nonverbal behaviors. The women also perceived the dominant task administrator as more sexual. In our second experiment, viewers rated the task administrator enacting dominant nonverbal behaviors as more likely than the less dominant task administrator to show gender-based attention, social attention, and sexually harassing behaviors. Taken together, our findings suggest an association between perceptions of dominance and sexuality.     

Undergraduates regard deviation from occupational gender stereotypes as costly for women

Studies from the 1970s have shown deviation from norms defining the gender-appropriateness of occupations to be costly for both women and men. Two hundred thirty undergraduates wrote open-ended stories and rated a stimulus person, Anne or John, who was described at the top of his/her class in medicine or one of four persistently gender-skewed fields: nursing, day care, electrical engineering, and electrician. Across all five occupations, negative imagery in stories about Anne and John in gender-incongruent occupations disappeared. However, when Anne succeeded in the two currently female-incongruent fields, raters treated her as a personal and social deviate by distancing themselves and by denigrating her role behaviors and personal traits, including her femininity. Parallel costs were not found for John nor were Anne's work-related qualities undermined. Undergraduates expect deviation from occupational gender-types in the 1990s to be personally costly for women, but not for men.The authors wish to thank Peggy Braam for her invaluable help with data collection and entry, and Arnold Kahn, John Zipp, Stephanie Riger, Lynne Berendsen, and Patricia Aniakudo. Parts of this paper were presented at the meetings of the Midwestern Psychological Association in Chicago in May 1993 and at the meetings of the American Psychological Association in Los Angeles in August 1994.     

Looking beyond gender: The effects of racial differences on tokenism perceptions of women

This study looks beyond gender to explore the impact of the social status of race and of token difference defined by race. In a 2 × 4 design, 53 African American women and 76 white women undergraduates rated a woman target, of the same race as themselves, who was described as being of the same race and gender as the dominant members of her work group or as a token defined by her gender alone, race alone, or both her race and gender. White women tokens were perceived to experience better social relations, more supportive colleagues, and lower stress than African American targets. Across African American and white raters/targets, token representation, defined by any ascribed status, was associated with expected negative tokenism outcomes relative to those projected for dominants. The omnirelevance of race toward understanding tokenism processes is discussed.We wish to thank Marchell Bass, Paulina Beres, Darya Burns, Roy Carrera, Nicole Cassie, Comilita Jackson, Susan Mathews, Pamela Ramsey, Catina Scott, and Aretha Strickland for their invaluable help with data collection and entry. These findings were presented at the meeting of the Midwestern Psychological Association in May 1995 in Chicago.
