Variation in the serotonin transporter gene modulates selective attention to threat

The 5-HTTLPR is an insertion/deletion polymorphism in the promoter region of the serotonin transporter gene. Prior research has revealed associations between the short-allele variant of this polymorphism, enhanced self-reported negative emotionality, and hypersensitivity of fear relevant neural circuits. In a sample of 50 healthy women we examined the role of 5-HTTLPR for cognitive-affective processing of phylogenetical fear-relevant stimuli (spiders) in a dot probe task. In contrast to homozygote long-allele carriers (ll), participants carrying at least 1 short allele (ss and sl) selectively shifted attention toward pictures of spiders, when these were presented for a duration of 2,000 ms. These results argue for an involvement of 5-HTTLPR in cognitive processing of threatening stimuli and thus, underpin its general role for individual differences in negative affect.     

Confounds in pictorial sets: The role of complexity and familiarity in basic-level picture processing

Complexity is conventionally defined as the level of detail or intricacy contained within a picture. The study of complexity has received relatively little attention-in part, because of the absence of an acceptable metric. Traditionally, normative ratings of complexity have been based on human judgments. However, this study demonstrates that published norms for visual complexity are biased. Familiarity and learning influence the subjective complexity scores for nonsense shapes, with a significant training x familiarity interaction [F(1,52) = 17.53, p < .05]. Several image-processing techniques were explored as alternative measures of picture and image complexity. A perimeter detection measure correlates strongly with human judgments of the complexity of line drawings of real-world objects and nonsense shapes and captures some of the processes important in judgments of subjective complexity, while removing the bias due to familiarity effects.     

Co-occurrence of Rape Myth Acceptance, Sexism, Racism, Homophobia, Ageism, Classism, and Religious Intolerance

Rape myth acceptance has been extensively studied. Little research is available, however, on the relationship of this variable to other oppressive belief systems. A sample of 492 male and 506 female college students completed the Illinois Rape Myth Acceptance Scale, the Attitudes Toward Women Scale (short form), the Neosexism Scale, the Modern and Old Fashioned Racism Scale, the Modern Homophobia Scale, a modified version of the Economic Belief Scale, the Fraboni Scale of Ageism, and the Marlowe–Crowne Social Desirability Scale (short form). Because there were no existing measures of intolerance toward multiple religions, the Religious Intolerance Scale was developed for this study (using relevant items from the Godfrey Richman Isms Scale). Findings here suggested that greater racism (both modern and old fashioned), sexism (both modern and old fashioned), homophobia (toward both gay men and lesbians), ageism, classism, and religious intolerance were each associated with greater rape myth acceptance. Moreover, each belief system collectively added to the prediction of rape myth acceptance, although sexism has the highest overlap with rape myth acceptance. Although gender did not moderate the relationship between oppressive belief systems and rape myth acceptance, results, across analyses, did indicate that men reported greater rape myth acceptance than women did. Results point to the interrelatedness of rape myth acceptance, racism, sexism, homophobia, classism, ageism, and religious intolerance.     

Psychopathologie und Behandlung der Borderline-Persönlichkeitsstörung

Zusammenfassung Das Wissen über Psychopathologie, Ätiopathogenese und Behandlungsmöglichkeiten der Borderline-Persönlichkeitsstörung (BPS) hat sich in den letzten Jahren deutlich verbessert. Heute sehen die meisten Wissenschaftler eine generalisierte Störung der Affektregulation im Zentrum der BPS, deren Ursachen in Wechselwirkungen zwischen genetischen Faktoren, traumatischen biographischen Erfahrungen und dysfunktionalen Verhaltensmustern liegen. Störungsspezifische Therapieverfahren, insbesondere die Dialektisch Behaviorale Therapie (DBT) nach Linehan, flankiert von psychopharmakologischer Behandlung, zeigen gute Behandlungsergebnisse sowohl im stationären als auch im ambulanten Bereich. In jüngster Zeit wurden viel versprechende Konzepte zur Behandlung schwerer komorbider Störungen [Alkohol und Drogenabhängigkeit, Posttraumatische Belastungsstörung (PTBS)] entwickelt.     

Perceptions of Police Use of Deadly Force

Recent police shootings of unarmed suspects have brought to bear harsh criticism of law enforcement use of deadly force. Two studies sought to investigate perceptions of police misuse of deadly force. Study 1 showed that as number of officers decreased and number of shots increased, perceptions of misuse of force were augmented. Number of shots per officer significantly predicted perceptions of misuse of force. Study 2 investigated the effects of social dominance orientation, blind patriotism, and right-wing authoritarianism. Results showed a significant interaction between number of officers, number of shots fired, and social dominance orientation. This personality variable was an especially strong predictor of misuse of force in situations involving the largest number of shots fired per officer.     

Why opening a door is as easy as eating an apple: A reply to Thompson-Schill and Botvinick (2006)

Martin and Cheng (2006) present evidence suggesting that difficulty in verb generation is related to the strength of associative links between nouns and verbs and not to competition from alternative verb responses. Specifically, they show that latencies for verb generation are related to the associative strength of the most frequently produced verb and not to the ratio of the strength of the first to the second most frequently produced verb. Thompson-Schill and Botvinick (2006) have provided modeling results indicating how the findings of Martin and Cheng might be accommodated in a competitive model. Here we discuss how two noncompetitive models account for the findings and why such models should be preferred.     

Epicureanism About Death and Immortality

In this paper I discuss some of Martha Nussbaum’s defenses of Epicurean views about death and immortality. Here I seek to defend the commonsense view that death can be a bad thing for an individual against the Epicurean; I also defend the claim that immortality might conceivably be a good thing. In the development of my analysis, I make certain connections between the literatures on free will and death. The intersection of these two literatures can be illuminated by reference to my notion of a Dialectical Stalemate.     

Relating different perspectives on how outcomes of behavior influence behavior

Many researchers have tackled the question of how behavior is influenced by its outcomes. Some have adopted a nonmechanistic (functional) perspective that attempts to describe the influence of outcomes on behavior. Others have adopted a mechanistic (cognitive) perspective that attempts to explain the influence of outcomes on behavior. Orthogonal to this distinction, some have focused on the influence of outcomes that a behavior had in the past, whereas others also consider the influence of outcomes that a behavior might have in the future. In this article, we relate these different perspectives with the goal of reducing misunderstandings and fostering collaborations between researchers who adopt different perspectives on the common question of how behavior is influenced by its outcomes.     

The rubber hand illusion depends on a congruent mapping between real and artificial fingers

The rubber hand illusion (RHI), in which a visible artificial hand is touched (or moves) synchronously with the participant's unseen own hand, indicates that body representations can undergo rapid changes. While several constraints for this illusion have been described, some reports highlight a remarkable flexibility of body representations, even contradicting a priori assumptions regarding body appearance and anatomy (e.g., the subjective embodiment of a third arm).
