The Role of Declarative and Procedural Knowledge in Capital Murder Sentencing1

This paper identifies rational orderliness and moral appropriateness as 2 norms that the United States Constitution requires for sentencing in capital murder trials. The courts convey these norms directly to jurors through jury instructions in the penalty phase of capital murder trials. To follow the instructions, jurors require accurate declarative knowledge (rules of law) and procedural knowledge (processes required to execute the rules) of state and federal sentencing law. Undergraduate mock jurors showed low accuracy for both types of knowledge after reviewing and listening to pattern jury instructions. Participants failed to offset aggravating factors with mitigating circumstances as the Missouri Approved Jury Instructions direct. The less knowledge that participants mastered about mitigation, the more certain they were of invoking the death penalty.     

Associative structure of differential inhibition: implications for models of conditioned inhibition

Following A+/X- training (with A, X, and + being a light, tone, and footshock, respectively), rats received extinction of A and the training context, extinction of the training context alone, or no extinction. The inhibitory potential of X was then assessed with conditioned lick suppression in a neutral context using both summation and retardation tests. Extinction of the training context alone and extinction of A and the training context reduced the inhibitory potential of X appreciably and equally. Hence, what is traditionally called differential inhibition appears to depend not on the excitatory value of A but on the excitatory value of the training context. In conjunction with what is known about other inhibitory training procedures, these results suggest that a conditioned inhibitor is a stimulus that has been paired with little or no reinforcement in the presence of an accompanying stimulus that predicts greater reinforcement.     

Gender differences in evaluating social-sexual conduct in the workplace

Qualitative interviews exploring gender differences in perceptions of sexual harassment were conducted with 100 full-time St. Louis area employees. Women more than men reported that telling dirty/sexual jokes was a non-harassing behavior, qualified behaviors as harassing when they happened in the workplace, and considered behaviors as non-harassing when the man's intentions were not harmful. Men more than women reported that requesting a date was a non-harassing behavior, qualified behaviors as harassing when the woman did not welcome the behavior, and considered behaviors as non-harassing when they did not violate workplace norms. Logistic regression analysis predicted the respondent gender with 86% accuracy. Finally, concept mapping suggested that when women think about harassers they are concerned with power and social aptitude, while men seem to be more concerned about the responsibility and psychological adjustment of perpetrators of sexual harassment. When women think about victims of harassment they are concerned with a woman's assertiveness and work effectiveness, while men are more concerned with the psychological state of the woman and how provocative she is when they think about victims of sexual harassment.     

Relationship Contexts as Sources of Socialization: An Exploration of Intimate Partner Violence Experiences of Economically Disadvantaged African American Adolescents

Intimate partner violence (IPV) among African Americans is a serious public health concern. Research suggest that African Americans adolescents, particularly those from economically disadvantaged communities, are at heightened risk for experiencing and perpetrating dating violence compared to youth from other racial and ethnic groups. In the present study, we examined different relationship contexts that are sources of IPV socialization. Semi-structured interviews were conducted with 22 economically disadvantaged African American adolescents. Content analysis yielded five relationship contexts through which the participants witnessed, experienced, and perpetrated IPV: (a) adolescents’ own dating relationships (64%), (b) siblings and extended family members (e.g., cousins, aunts, uncles) (59%), (c) parent-partners (27%), (d) friends (23%), and (e) neighbors (18%). Adolescents also frequently described IPV in their own dating relationships and in parent-partner relationships as mutual. Moreover, they appeared to minimize the experience of IPV in their own relationships. Efforts to reduce rates of IPV among economically disadvantaged African American adolescents should consider these relational contexts through which adolescents are socialized with regards to IPV and adolescents’ beliefs about mutual violence in relationships. Results highlight the importance of culturally relevant prevention and intervention programs that consider these relationship contexts.     

Care Orientation in the Teens as a Predictor of Young Adult Psychosocial Adjustment

The transition from adolescence to young adulthood is a watershed period in development that carries risk for poor psychosocial adjustment. It also carries potential for positive transitions into the caregiving roles and responsibilities of adult life. Research to date has predominantly focused on adolescent predictors of problematic rather than positive transitions; yet predictors of the latter hold equal (if not greater) promise for informing health promoting interventions. The purpose of this study was threefold: (1) to use Latent Profile Analysis (LPA) to define patterns of psychosocial adjustment and maladjustment in young adulthood (21-years of age); (2) to examine the unique role of adolescent prosocial behaviour (e.g., volunteering and civic engagement) in promoting adjustment and reducing maladjustment in young adulthood; and, (3) to examine whether protective developmental relationships are maintained after adjustment for other covariates including socio-economic background factors and personality characteristics. Data were drawn from the Victorian cohort of the International Youth Development Study (IYDS; N = 2407), a representative sample of students in Victoria, Australia. Students were assessed in Grade 9 (Mean age = 15-years) and followed up at age 21-years. LPA identified three psychosocial adjustment classes at age 21 defined as: (1) Adjusted (24.8 %); (2) Normative (63.9 %); and, (3) Maladjusted (11.3 %). Adolescent volunteering, belief in a moral order, family opportunities for prosocial behaviour, and commitment to school were associated with enhanced adjustment and reduced maladjustment in young adulthood. Findings highlight the potential benefit of interventions designed to enhance adolescent prosocial behaviours and care orientation in promoting healthy transitions into young adult life.     

Discriminant validity of the MMPI for borderline personality disorder

This study explores the discriminant validity of the MMPI in relationship to the DSM-III and the Diagnostic Interview for Borderlines (DIB) constructs of Borderline Personality Disorder (BPD). A two-way analysis of variance model assessed differences between inpatients (n = 42) and outpatients (n = 42) and between BPD and nonBPD patients. We compare the best discriminant model for the current samples with previous BPD discriminant functions. The present study assesses a wider range of psychopathology in which the MMPI appears to be relatively insensitive to the BPD construct while retaining the high specificity reported in previous studies. Implications for the use of the MMPI as a diagnostic instrument are discussed.     

PREDICTORS AND EFFECTS OF SELF-OBJECTIFICATION IN LESBIANS

The majority of research on self-objectification has focused on heterosexual women's experiences. This study sought to examine experiences of self-objectification in lesbian women. A path model was developed to examine the relationships between participants' feminist self-identification, levels of internalized heterosexism, objectified body consciousness, and the clinically relevant variables of negative eating attitudes and depression. As has been found with heterosexual women, body surveillance led to shame, which led to negative clinical outcomes. A direct path was also found between levels of surveillance and negative eating attitudes, consistent with previous research on self-objectification among lesbians. Feminist self-identification was not significantly related to the other variables, in contrast to previous research with heterosexual women. Internalized heterosexism was related to negative clinical outcomes, both indirectly through objectification variables and directly to depressive symptomatology. These results provide evidence that self-objectification and internalized heterosexism have negative impacts on the mental health of lesbian women.
