RESUMO

OBJECTIVES: The present studies examined two dimensions of racial ingroup identification, using them as predictors of Black and White Americans' attitudes toward paying college athletes. Following Leach et al. (2008), the present work distinguished between ingroup self-investment and ingroup self-definition. The central prediction was that respondent race and self-investment would interact in predicting compensation support. METHOD: In three studies (N = 352, N = 476, & N = 562), U.S. residents who were 18 or older and either Black or White completed an online survey in which they completed a self-report measure of racial identification, as well as reporting their opinion of paying college athletes. RESULTS: The results supported the prediction, demonstrating that Black respondents' support was higher than that for Whites, but this was especially the case at high levels of self-investment. The third study suggests that these effects were driven by respondents who believed that Black athletes made up a larger percentage of the pool of likely beneficiaries of compensation. Ingroup self-definition played no role as a moderator. CONCLUSIONS: Broadly speaking, it may be that, for policies whose likely beneficiaries are disproportionately Black, stronger racial self-investment serves to widen racial divides in support.

RESUMO

For the case of paracetamol, we show how terahertz time-domain spectroscopy can be used to characterize the solid and liquid phase dynamics. Heating of supercooled amorphous paracetamol from 295 K in a covered sample under vacuum leads to its crystallization at 330 K. First, form III is formed followed by the transformation of form III to form II at 375 K, to form I at 405 K, and finally melting is observed around 455 K. We discuss the difference between the featureless spectra of the supercooled liquid and its liquid melt. Lastly, we studied the onset of crystallization from the supercooled liquid in detail and quantified its kinetics based on the Avrami-Erofeev model. We determined an effective rate constant of k = 0.056 min(-1) with a corresponding onset of crystallization at T = 329.5 K for a heating rate of 0.4 K min(-1).

RESUMO

Three studies examined the relationship between need for cognition and support for punitive responses to crime. The results of Study 1 (N = 110) indicated that individuals high in need for cognition were less supportive of punitive measures than their low need for cognition counterparts. This finding was replicated in Study 2 (N = 1,807), which employed a nationally representative probability sample and included a more extensive battery of control variables. The purpose of Study 3 (N = 255) was to identify a third variable that might explain this relationship. This final study's results suggest that attributional complexity mediates the relationship between need for cognition and punitiveness. High need for cognition individuals are less supportive of punitive measures because they endorse more complex attributions for human behavior than their low need for cognition peers.

RESUMO

Two studies examined whether a criminal defendant's race influences Whites' sensitivity to legally relevant information. In Study 1, prosecution case strength ratings and guilt likelihood ratings were more sensitive to the strength of the defendant's alibi when he was Black than when he was White, if the experimental task was designed to elicit low processing motivation. Under high motivation, participants were equally sensitive to alibi strength, regardless of defendant race. In Study 2, the alibi strength manipulation was replaced with a manipulation of the effectiveness of the district attorney's cross-examination. As predicted, defense case strength ratings were more sensitive to the strength of the prosecutor's cross-examination with a Black defendant than with a White defendant-under low motivation. Under high motivation, sensitivity did not depend on defendant race. These results suggest that a Black defendant can elicit greater sensitivity to legally relevant information than will a White defendant.
