Previous research has investigated the manner in which absolute height impacts on jealousy and mate retention. Although relative height is also important, little information exists about the potential influence of sexual dimorphism in stature (SDS) within established relationships. The current study investigated the relationship between SDS and the satisfaction, jealousy and mate retention behaviors reported by men and women. Heterosexual men (n = 98) and women (n = 102) completed a questionnaire. Men in high SDS relationships reported the lowest levels of cognitive and behavioral jealousy, although the impact of SDS on relationship satisfaction was less clear. SDS was not associated with the overall use of mate retention strategies; SDS did however affect the use of three specific strategies (vigilance, monopolization of time, love and care). SDS did not affect women's relationship satisfaction, jealousy (cognitive, behavioral, or emotional) or the use of mate retention strategies (with the exception of resource display).  相似文献

Pica is dangerous behavior and often maintained by automatic reinforcement. We conducted a latency functional analysis (FA) using safe consumption items to verify that pica was maintained in part by automatic reinforcement and exclude participants for whom pica was likely maintained solely by attention. Next, we identified precursors to pica through a probability analysis and conducted a brief blocking assessment for participants' whose pica occurred in the alone and attention conditions of the FA. Finally, we compared blocking precursors with pica, touching an inedible item and the pica itself. Results showed that five of the six participants' pica was likely maintained by automatic reinforcement, and pica decreased during the brief blocking assessment for three of four participants. Results of the blocking comparison showed that blocking behaviors earlier in the response hierarchy was as effective as only blocking pica attempts for two participants and more effective for one participant.  相似文献

Professionals in science, technology, engineering, and math (STEM) are often stereotyped as geniuses and nerds (e.g., socially awkward). These stereotypes may demotivate some individuals from pursuing or remaining in STEM. However, these beliefs may enhance motivation among individuals who feel that they fit in with the stereotype. Guided by balanced identity theory and expectancy-value theory, our study investigated the effect of trait-based stereotypes about people in STEM among a sample of 256 U.S. high school students (Mage?=?16, 59% girls, 65% Asian, 15% Latinx, 10% White). We assessed students’ trait-based nerd and genius stereotypes about STEM and related self-concepts as well as their STEM motivation (competence and value beliefs). Consistent with balanced identity theory, the effect and direction of endorsing nerd-genius stereotypes was moderated by a student’s own self-concepts. Endorsing stereotypes was negatively related to motivation—but only among those low in the related self-concept. Among those high in related self-concepts (e.g., high in nerd-genius self-concept), endorsing STEM stereotypes (e.g., STEM is for geniuses) was unrelated to STEM motivation. Girls, underrepresented students of color, and potential first-generation college students may especially be negatively affected by the stereotypes due to a greater likelihood that these stereotypes will be incongruent with their self-concepts. Thus, trait-based stereotypes about people in STEM may perpetuate current gaps in STEM.

A method used in program evaluation and public health research called concept mapping is examined in this article for its usefulness in feminist research. This method embodies several defining characteristics of feminist social science. Concept mapping is a single method that integrates qualitative and quantitative approaches, provides an opportunity for participants to work together as a group to develop an understanding of a concept, and places the participants in control of interpretation. Over the course of a six-step process, a group of people are assembled to discuss an issue or concept, moving toward a group understanding of that concept, which is then represented in a visual picture, or map. Concept mapping was used in the current study to examine how community resources for sexual-assault victims could be improved. A national random sample of 168 rape-victim advocates provided ideas as to how the legal, medical, and mental health systems could better serve victims. A subgroup of advocates then constructed and interpreted a concept map. The map suggested that rape victims still face many problems in seeking community help. Twelve clusters of broad-based and specific system changes were identified (e.g., fighting victim blaming, community education, sensitizing medical staff, legal reform). Implications for research on sexual assault and feminist research methodology are discussed.  相似文献
