MMPI--2 Code-Type Congruence of Injured Workers

In this study, the authors examined the stability of Minnesota Multiphasic Personality Inventory--2 (J. N. Butcher, W. G. Dahlstrom, J. R. Graham, A. Tellegen, & B. Kaemmer, 1989) code types in a sample of 94 injured workers with a mean test-retest interval of 21.3 months (SD = 14.1). Congruence rates for undefined code types were 34% for high-point codes, 22% for 2-point codes, and 22% for 3-point codes. The data provide tentative evidence suggesting that defined code types are more stable than undefined code types. Cohen's kappa, a statistic that controls for chance agreement, was calculated for each clinical scale for both 2-point and 3-point code types. Only 2 of the 20 kappa coefficients were not significant at the p = .05 level.     

Influence of Levels of Abstractness on Reasoning Ability

Judgment by students of faculty effectiveness have relied, for the most part, on subjectively expressed responses to a series of “effectiveness traits” (cues). Simple averaging schemes have summarized the aggregate judgments, often resulting in (a) treating all cues as if they were of equal importance, and (b) inattention to the effects or measurement of individual differences of judges.

Multiple regression was used in this study to derive (empirically) individual cue utilization patterns (i.e., weights) for 10 effectiveness traits. Ss were compared to their subjectively expressed judgment scheme. Results indicate that Ss were moderately successful in expressing their actual cue utilization patterns; however, different judgment schemes were clearly observed.     

The role of perceived negativity in the moderation of African Americans' implicit and explicit racial attitudes

The present paper examines the relationship between Blacks' implicit and explicit racial attitudes and the extent to which perceived negativity from out-groups moderates the two attitudes. Results from two studies provide converging evidence that perceived negativity is related to both implicit and explicit attitudes, but in opposite directions. While perceived negativity showed a significant positive correlation with in-group bias on explicit measures, it was negatively correlated with in-group bias on implicit measures, such that Blacks who believed that Whites generally dislike Blacks showed significantly lower levels of implicit in-group bias compared with African Americans who believe that Whites positively regard Blacks. African Americans' level of exposure to out-groups was also negatively related to implicit in-group bias, but this relationship was mediated by perceived negativity.     

Two sets of twins with selective mutism: neuropsychological findings.

Neuropsychological data are reviewed from two sets of dizygotic twins presenting with selective mutism characterized by situation specific anxiety, extreme passive behavior, lack of responsivity, lack of peer interaction, and a chronic course of selective mutism. Both sets of twins had a history of prematurity and delayed speech development. One set of twins presented with normal intelligence and normal receptive language skills but with expressive language and oral motor sequencing difficulties. The second set of twins presented with Verbal IQ deficits and significant receptive and expressive language deficits. A summary of current conceptualizations regarding etiology and treatment of selective mutism is provided.     

Effect of dopamine on diuresis and its role in forming a renal CR

Four female mongrel dogs were used. Three had both ureters transplanted to the surface of the abdomen and one had a unilateral nephrectomy on the left and the right ureter transplanted to the abdomen. In dogs with externalized ureters our results with dopamine show changes in cardiac rate and renal secretion. The method used was 1) injection of dopamine, 2) measurement of subsequent changes in renal secretions (unconditional reflex), 3) and heart rate (HR). After 40 daily injections im of 2.5 mg/kg in normal saline the possible production of a diuretic CR was tested by injecting normal saline im and a tone was used as a signal. The control for normal saline showed no change in HR nor any of the constituents measured. The dopamine injection resulted in an increase of epinephrine in the urine of 300–600 per cent for 45 minutes; of norepinephrine of 200–500 per cent for 45 minutes; of an increase of 50 per cent in urine volume for 45 or more minutes; of absolute Na secretion of 49 per cent, of K, 20 per cent; of creatinine, 39 per cent (average in 3 dogs for 45 minutes diuresis). When the conditional stimulus (normal saline and tone) was given after several months training with the conditional signal and the injection of dopamine, there was no significant CR change to the HR nor any of the above components of urine. The conclusion is that in spite of the great increase of urine volume and composition of above substances there was no significant increase to the signals for the im injection of dopamine,i.e., no conditioning to dopamine.     

Impact of Remembering Childhood Sexual Abuse on Addiction Recovery for Young Adult Lesbians

This article examines the impact of childhood sexual abuse on young adult lesbians' sexual identity and their recovery from chemical dependency. The authors recommend that counselors assess for sexual orientation (past and present), sexual abuse, and possible dual diagnosis. Implications for counselors are discussed.     

Taking the watchdog off its leash: personal prejudices and situational motivations jointly predict derogation of a stigmatized source

Lower- and higher-prejudiced individuals may strategically derogate negatively stereotyped individuals. Regardless of degree of prejudice, participants with a directional goal to discredit a threatening message and its source were more likely to do so when the source belonged to a negatively stereotyped group. They also were less persuaded by that stigmatized source. When this directional goal was negated by making the message nonthreatening, lower-prejudiced individuals evaluated the stigmatized and nonstigmatized sources, and their messages, similarly and were equally persuaded by both sources. When an accuracy goal was simultaneously introduced, lower-prejudice participants again rated the stigmatized and nonstigmatized sources comparably yet continued to derogate the stigmatized speaker's message and were less persuaded by him. Removing the directional goal or adding the accuracy goal did not affect higher-prejudiced participants' evaluations. The importance of examining situational goals and individual differences when studying biased responding is discussed.     

Unique Aspects of Adolescent Sexual Victimization Experiences

This study explored females' adolescent experiences with sexual aggression using event-level data. A community sample of women, ages 18 to 30 years ( N = 319), were interviewed regarding their most recent unwanted sexual experience. Incidents were categorized as occurring during adolescence (ages 14 to 17) or adulthood (after age 18). Preliminary statistical comparison of adolescent and adult incidents revealed differences in perpetrators, type of aggression, preceding activities, and location of assault. Qualitative analytic techniques were then used to identify the contexts in which adolescent victimization occurred, as well as the factors contributing to adolescent vulnerability. Four contexts in which adolescents were sexually victimized emerged: Within Intimate Relationships, At Parties/Social Gatherings, Abuse by Authority Figures, and While Alone With a Friend. Thematic analysis revealed that inexperience with sex and dating, lack of guardianship, substance use, social and relationship concerns, and powerlessness contributed to adolescent vulnerability within these contexts.
