Disagreeable narcissism mediates an effect of BAS on addictive behaviors

Some forms of personality dysfunction that are associated with substance use and other externalizing behaviors, such as Narcissistic Personality Disorder, are characterized by low five-factor Agreeableness. Low Agreeableness and high Extraversion are both associated with the Behavioral Approach System in the revised Reinforcement Sensitivity Theory of Personality (RST; McNaughton & Corr, 2008). Meta-analyses examining personality predictors of Substance Use Disorders (Kotov et al., 2010) and Pathological Gambling (MacLaren et al., 2011) have implicated low Agreeableness but not Extraversion. In the present study, we sampled undergraduate students (N = 346) to examine relationships between two aspects of grandiose narcissism measured by the Narcissistic Personality Inventory (NPI), approach motivation measured by the BIS/BAS scales, and self-reported addictive behaviors. Disagreeable and Extraverted subscales of the NPI were examined for possible mediation of associations between BAS and addictive behaviors. The more disagreeable aspect of narcissism mediated the effects of BAS on drug use, gambling, sex, and maladaptive intimate relationships. These results suggest that one mechanism through which the Behavioral Approach System may promote addictive behavior among grandiose Narcissists is through its association with their aggressive and antagonistic interpersonal style.     

Anxiety and impression formation: Direct information rather than priming explains affect-congruity

Both affect-priming and affect-as-information theories predict that when people are anxious they will form affect-congruent impressions of others, but via different mechanisms. Affect-priming asserts that memory mediates the influence of anxiety on judgement, whereas affect-as-information asserts that people attribute anxiety to the target of judgement. As these theories predicted, anxious participants in Study 1 found an impression-formation target to be more threatening than did control participants. However, this effect was not mediated by memory, and was attenuated in Study 2 when anxious participants attributed their affect to a source other than the target. These findings suggest that anxious people form affect-congruent impressions of others because they attribute their anxiety to the impression-formation target rather than because anxiety primes affect-congruent memory.     

From Sectarian to Secular Control of Education The Case of Newfoundland

On September 2, 1997, Newfoundland transitioned from church to state control over education. Prior to this change, education had been controlled by churches. Recently, on November 9, 2000, an appeal to the Supreme Court of Canada by the Roman Catholic Church to declare the change unconstitutional was denied, settling the issue legally, although, perhaps, not politically. This article describes Newfoundland's educational system prior to the public referendum in 1997 that removed church control of education and explores some of the recent issues that have arisen since transition. It calls for further investigation into the effects of the change and the political, social, and economic forces that led to such a fundamental change.     

COMPARING PLEASURE AND PAIN: THE FUNDAMENTAL MATHEMATICAL EQUIVALENCE OF REWARD GAIN AND SHOCK REDUCTION UNDER VARIABLE INTERVAL SCHEDULES

The relationship between positive and negative reinforcement and the symmetry of Thorndike's law of effect are unresolved issues in operant psychology. Here we show that, for a given pattern of responding on variable interval (VI) schedules with the same programmed rate of food rewards (positive reinforcement VI) or electric shocks (negative reinforcement VI), there is a fundamental mathematical equivalence between reward gain and shock reduction. We also provide the first normative account of how animals should respond on a negative VI schedule, showing that it is better to space responses evenly than to respond with a variable interresponse time (IRT). Published data from rats, however, indicate that these animals respond irregularly, often with a burst of activity immediately following a shock. While this is irrational in the experimental setting, it may represent an appropriate response to the heterogeneity of stimuli commonly encountered in natural environments. We discuss the broader implications of our analysis for understanding how animals evaluate appetitive and aversive stimuli.     

THE CHANGING CRITERION DESIGN

This article describes and illustrates with two case studies a relatively novel form of the multiple-baseline design called the changing criterion design. It also presents the design's formal requirements, and suggests target behaviors and circumstances for which the design might be useful.     

Behavior analysis and education: An unfulfilled dream

This paper presents the author's view of why the promise for education visualized by early behavioral researchers is as yet unrealized. It points out that behavior analysis has had an important impact on special education but has had much less influence on teaching practice in regular classrooms. This is not seen as the fault of educators who have failed to embrace procedures developed by behavior analysts. Rather, the author contends, behavior analysts have failed to develop procedures that fit the ecology of the regular classroom. Those developed often require too much additional effort thereby punishing those who attempt their use. Another factor hindering widespread adoption is that behavior analysts have failed to disseminate their procedures and have not participated widely in undergraduate training of teachers. The paper concludes by noting that our success in special education provides a model for behavior analysts interested in regular education. By developing procedures that result in increased academic performance for entire classrooms without punishing the teachers who implement them, by making those procedures available commercially and by publishing in journals teachers read, and finally by participating more widely in undergraduate training, the unfulfilled dream of what behavior analysis has to offer education can be achieved.     

MRI findings in boys with specific language impairment

Magnetic resonance imaging scans of specifically language-impaired (SLI) boys were examined to determine whether atypical cerebral findings could be documented in children whose primary deficits were in language skills. Clinical examination of the scans failed to reveal any visually obvious lesions or abnormalities. In contrast, measurement of the scans revealed atypical perisylvian asymmetries in most of these subjects. The distribution of perisylvian asymmetries in SLI subjects was significantly different from the distribution in controls (p less than .01). Measurement of other brain regions revealed that extraperisylvian areas were occasionally deviant in individual SLI subjects; but no one region was consistently deviant across the SLI group. Thus, only atypical perisylvian asymmetries were linked to the language disorder. These neuroanatomical findings suggest that a prenatal alteration of brain development underlies specific language impairment.     

Between Abduction and the Deep Blue Sea

Stathis Psillos and James Ladyman et al. have recently joined battle over Bas van Fraassen's account of abduction and inference to the best explana-tion (IBE), and while van Fraassen makes many interesting criticisms, Psillos has had the best of the exchange. In part I of this paper I aim to extend Psillos' criticisms by suggesting that van Fraassen's critique of IBE is at odds, not only with The Scientific Image but also with his later work. Part II uses some of van Fraassen's ideas to suggest a third way between realist IBE and outright abductive scepticism.
