Positive Automatic Cognitions Mediate the Relationship Between Personality and Trait Positive Affect

Positive affect (PA) has emerged as a key well-being facet and a powerful predictor of physical and psychological well-being. One of the strongest predictors of PA is personality, particularly neuroticism and extraversion. However, the mechanisms via which personality affects PA are not well-understood. Consistent with theories that accord cognitive factors a role in mediating the relationship between personality and outcomes, we tested whether positive automatic thoughts (PATs) mediated the relationship between neuroticism, extraversion, and PA among 199 college students (137 women, 70% White, 66% first and second year students, mean age = 24.13, SD = 8.86). Consistent with hypotheses, structural equation modeling indicated that PATs fully mediated the relationship between both neuroticism and extraversion and PA. The structural model fit the data well, χ²/df = 2.33, CFI = .96, SRMR = .07, RMSEA = .08 (90% CI: .06, .10), AIC = 172.45, and accounted for 58% of the variance in PA. An alternative model in which personality predicted PA, which in turn predicted PATs, did not provide as good a fit to the data, χ²/df = 3.03, CFI = .94, SRMR = .09, RMSEA = .10 (90% CI: .08, .12), AIC = 207.40. Models in which negative automatic thoughts (NATs) were construed as fully [χ²/df = 4.46, CFI = .95, SRMR = .08, RMSEA = .13 (90% CI: .11, .16)] or partially [χ²/df = 4.04, CFI = .96, SRMR = .06, RMSEA = .12 (90% CI: .10, .15)] mediating the relationship between neuroticism and negative affect did not provide a good fit to the data. A final model in which negative affect was tested a mediator of the relationship between neuroticism and NATs also did not fit the data well, χ²/df = 4.03, CFI = .96, SRMR = .07, RMSEA = .12 (90% CI: .10, .15).     

Development and Testing of an Abbreviated Numeracy Scale: A Rasch Analysis Approach

Research has demonstrated that individual differences in numeracy may have important consequences for decision making. In the present paper, we develop a shorter, psychometrically improved measure of numeracy—the ability to understand, manipulate, and use numerical information, including probabilities. Across two large independent samples that varied widely in age and educational level, participants completed 18 items from existing numeracy measures. In Study 1, we conducted a Rasch analysis on the item pool and created an eight‐item numeracy scale that assesses a broader range of difficulty than previous scales. In Study 2, we replicated this eight‐item scale in a separate Rasch analysis using data from an independent sample. We also found that the new Rasch‐based numeracy scale, compared with previous measures, could predict decision‐making preferences obtained in past studies, supporting its predictive validity. In Study, 3, we further established the predictive validity of the Rasch‐based numeracy scale. Specifically, we examined the associations between numeracy and risk judgments, compared with previous scales. Overall, we found that the Rasch‐based scale was a better linear predictor of risk judgments than prior measures. Moreover, this study is the first to present the psychometric properties of several popular numeracy measures across a diverse sample of ages and educational level. We discuss the usefulness and the advantages of the new scale, which we feel can be used in a wide range of subject populations, allowing for a more clear understanding of how numeracy is associated with decision processes.

Freud's Ironically Jewish Science: Commentary on Paper by Jill Salberg

In his commentary on Jill Salberg's integrative and contextualizing article, “Hidden in Plain Sight: Freud's Jewish Identity Revisited,” Aron examines several ideas related to Freud's ironically “Jewish science.” First, this commentary takes up the question of what it has meant to speak of a “Jewish science” historically, and what it might mean today. Shockingly, Aron shows that the rise and fall of psychoanalysis has been traced to Jewish influence. He then expands on Salberg's article by reviewing the relationship between circumcision and castration and considers the impact of Freud's Jewish identity and his anxiety about anti-Semitism on the structure of the psychoanalytic method and specifically on Freud's discovery of the “royal road.”     

Women on the Couch: Genital Stimulation and the Birth of Psychoanalysis

Following Freud's emphasis on his rejection of hypnosis as leading up to the development of psychoanalysis, there has been little mention in the psychoanalytic literature of the larger context of the somatic medical treatment of hysteria within which Freud treated his hysterical patients, and which Freud himself practiced. We contend that Freud's emphasis obscured his association with massage, electrotherapy, and the procedure of genital stimulation practiced by his medical colleagues in the treatment of hysteria. We show that the history of genital stimulation—including its obfuscation, desexualization, medicalization, and co-option from traditional women healers by an exclusively male medical establishment—provides us with the background for a more sophisticated understanding of the context in which Freud developed his theories. Specifically, we examine the contribution of this understanding to Freud's theoretical emphases on autonomy and individuality, abstinence and the renunciation of gratification, penis envy, clitoral versus vaginal orgasm, mature genital sexuality, and the “repudiation of femininity” as the “bedrock” of psychoanalysis. We demonstrate that Freud's position as a Jew in an anti-Semitic milieu fueled his efforts to distance his psychoanalytic method from the more prurient practices of his day, including one his society associated with Jewish doctors and patients.     

Differential endocannabinoid regulation of extinction in appetitive and aversive Barnes maze tasks

CB 1 receptor-compromised animals show profound deficits in extinguishing learned behavior from aversive conditioning tasks, but display normal extinction learning in appetitive operant tasks. However, it is difficult to discern whether the differential involvement of the endogenous cannabinoid system on extinction results from the hedonics or the required responses associated with the disparate tasks. Here, we report that the CB 1 receptor antagonist rimonabant disrupts extinction learning in an aversive, but not in an appetitive, Barnes maze conditioning task. Accordingly, these results provide compelling support for the hypothesis that the endogenous cannabinoid system plays a necessary role in the extinction of aversively motivated behaviors but is expendable for appetitively motivated behaviors.
