Perceived racism and cardiovascular reactivity and recovery to personally relevant stress.

This study evaluated cardiovascular responses (CVR) to an active speech task with blatantly discriminatory (BRC) versus neutral (NRC) stimuli and an anger recall task in a sample of Black men (N = 73; age 18 to 47). Diastolic blood pressure scores were higher for NRC versus BRC stimuli during anger recall (p = .05). Moreover, persons in the NRC group who perceived high levels of racism (vs. no racism or BRC group) during active speech showed larger increases in blood pressure across postspeech rest, anger recall, and subsequent rest (p = .03). The notable elevation in CVR in response to an ambiguous event extends current models of racism suggesting that subtle racism is a psychosocial stressor that erodes health through chronically elevated CVR.     

Family satisfaction with medical care after traumatic brain injury

Ratings during acute and follow-up care by 35 families having members with traumatic brain injury showed none of the medical facilities met families' needs though some aspects of patients' care were rated higher in hospitals. Findings suggest comprehensive surveys are needed.

Experimental evaluation of matching via a commercially available basketball video game

Many recent nonlaboratory-based quantitative analyses of behavior have relied on archival competitive sporting data. However, the ratio-based reinforcement schedules in most athletic competitions and the correlational nature of archival data analyses raise concern over the contributions of such findings to the behavior analytic literature. The current experiment evaluated whether matching in a human operant paradigm would approximate matching observed in nonlaboratory-based sports data. To this end, we used in-game attributes to parametrically manipulate 2- and 3-point shooting in a commercially available basketball video game. The behavior of 6 of 9 participants conformed to the generalized matching equation. These results suggest matching in sporting contexts may be a product of restricted nonindependent concurrent random-ratio schedules. Implications of this experiment, including those in applied behavior analysis and potential influence on gamification, are discussed.     

Fantasy proneness, dissociation, and DSM-IV axis II symptomatology

Scores on the Inventory of Childhood Memories and Imaginings (S. C. Wilson & T. X. Barber, 1981) identified fantasizers and controls who were administered the Structured Interview for DSM-IV Personality (SIDP-IV; B. Pfohl, N. Blum, & M. Zimmerman, 1994) and the Dissociative Experiences Scale (DES; E. M. Bernstein & F. W. Putnam, 1986). Fantasizers had increased rates of Cluster A and B personality disorders but were equivalent to controls in Cluster C diagnoses. For both Clusters A and B, 55% of the fantasizers received clinical diagnoses. Fantasizers had significantly higher DES, DES-T (N. G. Waller, F. W. Putnam, & E. B. Carlson, 1996), and Normal Dissociative Index scores. Although nearly one half of the fantasizers' DES-T patterns were classified within the pathological dissociative taxon (N. G. Waller & C. A. Ross, 1997), none of the controls and only 10.03% of the original screening sample received this classification. Both Axis II pathology and pathological dissociation were associated with fantasy proneness.     

Adult mice maintained on a high-fat diet exhibit object location memory deficits and reduced hippocampal SIRT1 gene expression

Mounting evidence has established that diet-induced obesity (DIO) is associated with deficits in hippocampus-dependent memory. The bulk of research studies dealing with this topic have utilized rats fed a high-fat diet as an experimental model. To date, there has been a paucity of research studies that have established whether the memory deficits exhibited in DIO rats can be recapitulated in mice. Moreover, the majority of experiments that have evaluated memory performance in rodent models of DIO have utilized memory tests that are essentially aversive in nature (i.e., Morris water maze). The current study sought to fill an empirical void by determining if mice maintained on a high-fat diet exhibit deficits in two non-aversive memory paradigms: novel object recognition (NOR) and object location memory (OLM). Here we report that mice fed a high-fat diet over 23 weeks exhibit intact NOR, albeit a marked impairment in hippocampus-dependent OLM. We also determined the existence of corresponding aberrations in gene expression within the hippocampus of DIO mice. DIO mice exhibited significant reductions in both SIRT1 and PP1 mRNA within the hippocampus. Our data suggest that mice maintained on a high-fat diet present with impaired hippocampus-dependent spatial memory and a corresponding alteration in the expression of genes that have been implicated in memory consolidation.     

Imagine Me and You,I Do: Effects of imagined intergroup contact on anti‐fat bias in the context of job interviews

Imagined intergroup contact (IIC) has been demonstrated to alleviate prejudice toward social groups as a whole, but the extent to which it prevents biases in ratings of individual job candidates has not yet been examined. This study uses a simulated employment interview where a female candidate either higher or lower in body fat is rated by participants who have undergone an IIC or a control manipulation. IIC successfully alleviated discrimination in ratings of interviewee competence but had no significant effect on ratings of warmth. Competence ratings fully mediated the effect of the two‐way interaction of IIC and interviewee body fat on a dichotomous hiring recommendation provided 1 week later. IIC may be an effective and inexpensive intervention for reducing bias in job interview contexts.     

Varieties of Reflection in Kant's Logic

For Kant, ‘reflection’ (Überlegung, Reflexion) is a technical term with a range of senses. I focus here on the senses of reflection that come to light in Kant's account of logic, and then bring the results to bear on the distinction between ‘logical’ and ‘transcendental’ reflection that surfaces in the Amphiboly chapter of the Critique of Pure Reason. Although recent commentary has followed similar cues, I suggest that it labours under a blind spot, as it neglects Kant's distinction between ‘pure’ and ‘applied’ general logic. The foundational text of existing interpretations is a passage in Logik Jäsche that appears to attribute to Kant the view that reflection is a mental operation involved in the generation of concepts from non-conceptual materials. I argue against the received view by attending to Kant's division between ‘pure’ and ‘applied’ general logic, identifying senses of reflection proper to each, and showing that none accords well with the received view. Finally, to take account of Kant's notion of transcendental reflection I show that we need to be attentive to the concerns of applied logic and how they inform the domain-relative transcendental logic that Kant presents in the first Critique.
