Mothers' speech to their 1-year-old infants in home and laboratory settings

The speech of mothers and their 1-year-old infants was compared in the home and in the laboratory playroom. The home and laboratory settings were similar for measuring the number of actual words that infants spoke and were similar for measuring the complexity of the mother's speech, including the number of different words, the type-token ratio, and the length of the utterances. Infants vocalized at similar rates in the two settings, but mothers spoke at a faster rate in the laboratory playroom. The usefulness of a preliminary warm-up period was supported by the finding that for the second half of the sessions, mothers slowed their rate of speech and increased the complexity of their speech.     

Prior cocaine exposure disrupts extinction of fear conditioning

Psychostimulant exposure has been shown to cause molecular and cellular changes in prefrontal cortex. It has been hypothesized that these drug-induced changes might affect the operation of prefrontal-limbic circuits, disrupting their normal role in controlling behavior and thereby leading to compulsive drug-seeking. To test this hypothesis, we tested cocaine-treated rats in a fear conditioning, inflation, and extinction task, known to depend on medial prefrontal cortex and amygdala. Cocaine-treated rats conditioned and inflated similar to saline controls but displayed slower extinction learning. These results support the hypothesis that control processes in the medial prefrontal cortex are impaired by cocaine exposure.     

The role of temporal shifts in turnover processes: it's about time

To better understand the process of organizational withdrawal, a turnover model incorporating dynamic predictors measured at 5 distinct points in time was examined by following a large occupationally and organizationally diverse sample over a 2-year period. Results demonstrated that turnover can be predicted by perceived costs of turnover, organizational commitment, and critical events measured soon after entry into the organization. Occupational unemployment rates, job satisfaction, and search for alternative jobs also become significant predictors when measured over time. Critical events predicted turnover in a manner distinct from the operation of attitudes, consistent with the unfolding model (Lee & Mitchell, 1994). The path to turnover was marked by consistently low perceived costs of turnover and satisfaction, decreases in commitment, and increases in job search over time.     

Job-search persistence during unemployment: a 10-wave longitudinal study

Dynamic predictors of job-search intensity over time are examined in a large 10-wave longitudinal study of unemployed individuals. Two sets of variables relevant to the examination of job search from a dynamic, self-regulatory perspective--core self-evaluations (T. A. Judge, A. Erez, & J. E. Bono, 1998) and the theory of planned behavior (I. Ajzen, 1991)--were used to guide our examination. Results suggest core self-evaluation is related to average levels of job-search intensity over time. Job-search intentions mediated the relationship between subjective norms and job-search self-efficacy in the prediction of job-search intensity in the following 2 weeks. Both Time 1 and cumulative job-search intensity predict reemployment. This repeated-measures study contributes to research on job search that has been primarily cross-sectional or included few time waves.     

Experimenter Influences and Children's Cross-Gender Behavior

We measured 120 third and fourth gradechildren's willingness to participate in severalbehavioral tasks after assessing their verbalpreferences for gender-typed and cross-gender activities(children were primarily Caucasian). Before beginning eachtask, children were either encouraged to or discouragedfrom engaging in cross-gender activities, or they wereencouraged to choose whatever activities they preferred. Relative to the control condition,experimenters were able to reduce but not increase theproportion of cross-gender activities children engagedin. Children who gave high ratings to cross-gender items during the preference test were more willingthan other children to take cross-gender selectionshome.     

A task for use in decision-making research and practice

This study was designed to refine the Decision-Making Questionnaire (DMQ) developed in earlier research for ease of use. Previous work had indicated that the longer forms of the DMQ, whilst reasonably reliable and valid, were too lengthy to be easily incorporated into research and practice. Sixtythree individual workers from different organizations participated in this study by completing the 10-scenario DMQ, which takes about 45 minutes. A series of analyses indicated how this 10-scenario scale was most effectively reduced to a two-scenario scale, which takes less than 15 minutes to complete. The results are discussed in terms of their research value and practical utility. The Decision-Making Task and its scoring protocol are appended.     

The Effect of Social-Comparison Feedback on Aggressive Responses to Erotic and Aggressive Films1

A study assessed the effects of social-comparison cues and filmed violence on aggression toward women. Under the auspices of validating some film clips for use in future research, males viewed either erotic, violent sexual, or violent nonsexual films. A male confederate provided social comparison feedback by indicating (or not indicating) that the film degraded women. Self-reports of sexual arousal, affective responses to the films, perceptions of violence, perceptions of pornography, and perceptions of portrayal of women were measured. In a purportedly unrelated learning experiment, males were given the opportunity to aggress toward a female confederate through electric shock. Intensity and duration of shock were measured. Social comparison information caused reductions in self-reports of sexual arousal, affect, and increased perceptions of violence in the erotic film condition only. Social-comparison information caused males to rate the depiction of women as more negative in both the erotic and violent nonsexual conditions. Regardless of film type, social comparison information caused a reduction in perceived realism of the films. Only film condition affected perceptions of pornography, with greater sexual content judged as more pornographic. Social-comparison information reduced the intensity of shocks delivered. Finally, social-comparison information led to reduced duration of shock in all film conditions; however, this effect appeared to dissipate in the violent sexual condition. Implications are discussed.     

Examining Sex Differences in Altering Attitudes About Rape: A Test of the Elaboration Likelihood Model

This intervention sought to improve first-year college students' attitudes about rape. The Elaboration Likelihood Model (ELM) was used to examine men and women's attitude change processes. Both quantitative and qualitative methodologies were used to examine how men and women construed rape prevention messages. Results indicated numerous sex differences in the ways in which men and women experienced and changed during and after the rape prevention intervention. Women seemed to use more central-route attitude change processes and showed more lasting change from the intervention at 2-month follow-up, whereas men seemed to attend more to peripheral cues of the speaker and demonstrated more transient attitude change.     

Managers' perceptions of workplace romances: An interview study

Although workplace romances occur frequently, no research has directly examined managers' perceptions of these relationships. In this study, managers (N=30) were interviewed about workplace romances. Included in these interviews were questions about organizational policies regarding these relationships, knowledge of prior or current workplace romances, and reactions to workplace romances and the participants in those relationships. Managers also responded to 12 items designed to assess the effect of different characteristics of workplace romances on perceptions of the need for management intervention. Responses to these items indicated that managers were most likely to recommend intervention when the relationship occurred between unequal organizational status participants, and it was negatively affecting the work group. The hypothesis that women managers would respond more negatively than would male managers to workplace romances was not supported. Factors that may affect managers' reactions to participants in workplace romances are discussed.This paper is based on research conducted by the first author with the direction of the second author.
