Sex differences in college student-teacher interactions: Fact or fantasy?

On-site observations analyzing student-teacher interaction for 50 college classes, matched by level, subject, and teacher's sex, revealed no difference in number and type of interactions in which male and female students participated. In female-taught classes, style differences were found: Male students' interactions were characterized by more student-teacher exchanges than females' interactions. From student questionnaires, differences in office visitation patterns were revealed, showing an apparent relationship to sex: Female students visited more female than male instructors. However, closer examination showed the student's major to be the key variable influencing visitation patterns. Results point to the need for testing a variety of variables in addition to sex before drawing conclusions about sex-related behavior.Ordering of authors was determined alphabetically.

Organization of the bilingual lexicon: Categorical versus alphabetic cuing in Russian-English bilinguals

The mechanism by which Russian native speakers store and retrieve Russian and English words from lexical memory was investigated in two experiments in which fluency of retrieval was compared for categorical and alphabetic cues. We hypothesized that fluency in Russian would be higher for categorical cues but that fluency in English would be higher for alphabetical cues because native language words would have been stored by meaning, while second-language words would have been stored according to dictionary usage. Subjects retrieved more Russian than English words with categorical cues, but their retrieval was the same for the two languages with alphabetic cues. In addition, fluency was greater overall with alphabetical than categorical cues. We attributed the greater fluency in Russian with the categorical cues to the early age at which the concepts were acquired, which made them more accessible in the native language. These findings support the idea that access codes for words may vary depending upon how they are originally learned.This research was supported by Research Grants AFOSR 89-0442 and F49620-92-J-0119 from the U.S. Air Force Office of Scientific Research to Joan Gay Snodgrass.

Doubly Bound: The Impact of Gender and Race on the Politics of Black Women

Gender has been thought to be less salient than race among black women. Data from two national surveys of black Americans, conducted in 1984 and 1996, show that black women identify as strongly on the basis of their gender as their race, and that these gender and racial identities are mutually reinforcing. Nevertheless, among black women, their identification with their race more powerfully affected their political attitudes than did their identification on the basis of gender, except in instances where the interests of blacks directly conflict with the interests of women. These empirically based findings speak to the issue of why the attitudes of black women toward contemporary gender issues can sharply diverge from those of white women.     

Visual-word recognition thresholds for screen-fragmented names of the Snodgrass and Vanderwart pictures

The set of names corresponding to the pictures from Snodgrass and Vanderwart (1980) were screen fragmented by means of a series of procedures implemented in Microsoft QuickBasic on a Macintosh microcomputer. Words were screen fragmented by deleting blocks of pixels from their images rather than by deleting individual letters. The screen-fragmentation procedure is particularly useful for the present set of words, in which a large proportion of the names of the pictures are short (fewer than five letters). The screen-fragmentation procedure can produce any number of fragmentation levels. In the present implementation, eight levels of fragmented images were produced, to correspond to the eight levels available for the Snodgrass and Vanderwart pictures.     

HIV, Sex, and Social Change: Applying ESID Principles to HIV Prevention Research

The HIV epidemic has been the most significant public health crisis of the last 2 decades. Although Experimental Social Innovation and Dissemination (ESID) principles have been used by many HIV prevention researchers, the clearest application is the series of model-building and replication experiments conducted by Kelly and colleagues. The model mobilized, trained, and engaged key opinion leaders to serve as behavior change and safe-sex endorsers in their social networks. This paper illustrates how ESID principles were used to develop, test, and disseminate an innovative social model and discusses the challenges of applying ESID methodology in the midst of a public health emergency.
