Do infants express discrete emotions? Adult judgments of facial,vocal, and body actions

Adult judges were presented with videotape segments showing an infant displaying facial configurations hypothesized to express discomfort/pain, anger, or sadness according to differential emotions theory (Izard, Dougherty, & Hembree, 1983). The segments also included the infant's nonfacial behavior and aspects of the situational context. Judges rated the segments using a set of emotion terms or a set of activity terms. Results showed that judges perceived the discomfort/pain and anger segments as involving one or more negative emotions not predicted by differential emotions theory. The sadness segments were perceived as involving relatively little emotion overall. Body activity accompanying the discomfort/pain and anger configurations was judged to be more jerky and active than body activity accompanying the sadness configurations. The sadness segments were accompanied by relatively little body movement overall. The results thus fail to conform to the predictions of differential emotions theory but provide information that may contribute to the development of a theory of infant expressive behavior.This article is based on the second author's master's thesis.

Pretrial Predictors of Judgments in the O. J. Simpson Case

Five hundred seventy-eight community college and four-year state university students responded to questionnaires designed to assess judgments regarding O. J. Simpson's guilt, beliefs surrounding the case, general attitudes, and background information. Although African Americans were more likely to perceive Simpson as innocent than non–African Americans, correlation analyses revealed that, for the most part, the same predictors explained African Americans' and non–African American's judgments of guilt. Finally, set-wise hierarchical regression analyses indicated that case-related beliefs that Simpson abused Nicole Brown Simpson and that the system was biased against him accounted for more significant incremental variance than did demographic variables such as age and ethnicity, personal experiences, and general attitudes. The results suggested that the racial polarization emphasized in public polls does not reflect the diversity of beliefs that existed within both African American and European American populations.     

Childhood sexual abuse patterns, psychosocial correlates, and treatment outcomes among adults in drug abuse treatment

This study reports on the effects of having a history of childhood sexual abuse (CSA) on treatment outcomes among substance abusing men and women (N = 2,434) in a national, multisite study of drug treatment outcomes. A history of CSA was reported by 27.2% of the women and 9.2% of the men. Controlling for gender, compared to patients without CSA, patients reporting CSA were younger at entry into the current drug treatment, were more likely to be White, were more likely to have a comorbid mental disorder, be alcohol or cocaine dependent, had higher levels of criminal activities, had a higher level of problem recognition, and had a more negative peer influence. Controlling for these correlates, a history of abuse was related to a lower likelihood of posttreatment abstinence.     

Comparison of Poverty and Income Disparity of Single Mothers and Fathers Across Three Decades: 1990–2010

As the potential for more children being raised by single parents increases, so does the societal need to examine this phenomena of single parent earnings and the impact it will have on the ability to support a family above the poverty line. Research suggests a substantial pay gap between men and women, but most research is limited to individuals in traditional families. This study explores income disparity and poverty between single mothers and single fathers across three decades (1990–2010), using a US nationally representative sample. Based on human capital theory, our analysis reveals that single mothers were more likely to be in poverty at far greater rates than single fathers, after controlling for a host of demographic, human capital, and work related variables. We also found that a contributing factor to this disparity is that single mothers were penalized for having more children while single fathers were not. We find that gendered poverty and the gender pay gap narrowed between 1990 and 2000, but have stayed stable since. Overall, human capital decreases the gender income and poverty gap, but a substantial gap still remains. Implications for policy-makers are discussed.     

Group decision making under uncertainty a note on the aggregation of “ordinal probabilities”

This paper is a first attempt to study the problem of aggregation of individual ordinal probabilistic beliefs in an Arrowian framework. We exhibit some properties an aggregation rule must fulfil; in particular we prove the existence of a quasi-dictator.
