Inter‐racial contact and the own‐race bias for face recognition in South Africa and England

Own‐race bias, where people are more accurate recognizing faces of people from their own race than other races, can lead to misidentification and, in some cases, innocent people being convicted. This bias was explored in South Africa and England, using Black and White participants. People were shown several photographs of Black and White faces and were later asked if they had seen these faces (and several fillers). In addition, participants were given a questionnaire about inter‐racial contact. Cross‐race identification accuracy for Black participants was positively correlated with self‐reported inter‐racial contact. The confidence–accuracy relationship was strongest when making own‐race judgements. Copyright © 2003 John Wiley & Sons, Ltd.     

A turnover model for the Mexican maquiladoras

Existing turnover models have been developed and tested almost exclusively in Anglo cultures. Thus, there is reason to question whether these models apply to workers elsewhere. We addressed this question using as participants 47 Mexican maquiladora workers. Through interview responses analyzed using a variation of grounded theory-building, we inductively created a model of voluntary turnover with research propositions. We then compared the new model to traditional turnover models, concluding that many of their constructs and mechanisms are familiar in the maquiladoras. However, the cultural and economic environment perceived by the workers help determine the precise antecedents, their salience, and the strength of their linkages with turnover. Finally, we suggest how turnover research might be extended to better apply to workers in other cultures.     

Who Benefits From What? Drive for Thinness as a Moderator of Responsiveness to Different Eating Disorder Prevention Messages1

This research examined how women respond to different types of messages regarding eat ing disorders, and specifically whether women's degree of drive for thinness moderated their responsiveness to particular messages. In this study, 112 undergraduate women were randomly assigned to receive a condition focusing on either healthy eating or disordered eating. First, and as hypothesized, findings at an immediate posttest revealed that women found the healthy eating condition more enjoyable, personally relevant, and interesting, whereas they found the disordered eating condition more anxiety‐provoking and fear‐inducing. Second, and contrary to predictions, findings at the 3‐month follow‐up indicated that those who were high on drive for thinness were hurt by participation in the disordered eating condition, whereas those who were low on drive for thinness were helped by participation in this condition. Discussion focuses on the theoretical and applied implications of these findings.     

Noise,Economy, and the Emergence of Information Structure in a Laboratory Language

The acceptability of sentences in natural language is constrained not only grammaticality, but also by the relationship between what is being conveyed and such factors as context and the beliefs of interlocutors. In many languages the critical element in a sentence (its focus) must be given grammatical prominence. There are different accounts of the nature of focus marking. Some researchers treat it as the grammatical realization of a potentially arbitrary feature of universal grammar and do not provide an explicit account of its origins; others have argued, however, that focus marking is a (grammaticalized) functional solution to the problem of efficiently transmitting information via a noisy channel. By adding redundancy to highlight critical elements in particular, focus protects key parts of the message from noise. If this information‐theoretic account is true, then we should expect focus‐like behavior to emerge even in non‐linguistic communication systems given sufficient noise and pressures for efficiency. We tested this in an experiment in which participants played a simple communication game in which they had to click cells on a grid to communicate one of two line figures drawn across the grid. We manipulated the noise, available time, and required effort, and measured patterns of redundancy. Because the lines in many cases overlapped, meaning that only some parts of each line could be used to distinguish it from the other, we were able to compare the extent to which effort was expended on adding redundancy to critical (non‐overlapping) and non‐critical (overlapping) parts of the message. The results supported the information‐theoretic account of focus and shed light on the emergence of information structure in language.
