Pro- and Antisaccades: Dissociating Stimulus and Response Influences the Online Control of Saccade Trajectories

The authors examined whether the diminished online control of antisaccades is related to a trade-off between movement planning and control or the remapping of target properties to a mirror-symmetrical location (i.e., vector inversion). Pro- and antisaccades were examined in a standard no-delay schedule wherein target onset served as the movement imperative and a delay cuing schedule wherein responses were initiated 2,000 ms following target onset. Importantly, the delay cuing schedule was employed to equate pro- and antisaccade reaction times. Online control was evaluated by indexing the strength of trajectory amendments at normalized increments of movement time. Antisaccades exhibited fewer online corrections than prosaccades, and this result was consistent across cuing schedules. Thus, the diminished online control of antisaccades cannot be tied to a trade-off between movement planning and control. Rather, the authors propose that the intentional nature of dissociating stimulus and response (i.e., vector inversion) engenders a slow mode of cognitive control that is not optimized for fast oculomotor corrections.     

An Empirical Examination of a Model of Social Climate in Elementary Schools

Although Gerbner and Gross (1976) maintained that television viewing cultivates impressions of the real world that are distorted in the direction of the TV version of reality, several studies (e.g., Doob & Macdonald, 1979) have found no relationship between viewing and perceptions of crime in the respondent's neighborhood. It is possible, however, that TV viewing may not affect perceptions of crime in the respondent's immediate environment but may affect perceptions of crime in more distant settings. In two separate studies, we examined the effects of TV viewing on perceptions of crime in the immediate neighborhood and on perceptions of crime in more distant, urban settings. Study 1, based on 372 nationwide telephone interviews, found that the total amount of TV viewed is related to fear of distant urban setting (i.e., New York City) but not to fear of respondent's own city or to fear of respondent's immediate neighborhood. Study 2, based on a survey of 192 undergraduates, found that the total amount of TV viewed is related to fear of distant urban setting (i.e., NYC) and to fear of less distant urban setting (i.e., downtown Chicago) but not to fear of respondent's immediate neighborhood. The implications of these studies for clearing up past confusions in the cultivation hypothesis literature are discussed.     

Slow categorization but fast naming for photographs of manipulable objects

Previous research investigating the influence of object manipulability (the properties of objects that make them appropriate for manual action) on object identification has not tightly controlled for effects of both object familiarity and age of acquisition of objects. The current research carefully controlled these two variables on a balanced set of 120 photographs and showed significant effects of object manipulability during object categorization (Experiment 1) and object naming (Experiment 2). Critically, the effects showed a manipulability-effect reversal, with faster categorization of non-manipulable objects, but faster naming of manipulable objects, suggesting that task moderates the direction of the manipulability effect. Exposure duration (the amount of time the object was visible to participants) was also investigated, but no interactions between exposure duration and manipulability were found. These results indicate that not only can manipulability influence object identification, but the way in which it does depends on the task.     

Why do people behave immorally when drunk?

Alcohol intoxication is a major source of antisocial behavior in our society, strongly implicated in various forms of interpersonal aggression. Yet, moral philosophers have paid surprisingly little attention to the literature on alcohol and its effects. In part, this is because philosophers who have adopted a more empirically informed approach to moral psychology have gravitated toward moral sentimentalism, while the literature on alcohol intoxication fits very poorly with the sentimentalist account. Most contemporary research on the psychological effects of alcohol is focused upon variants of the “disinhibition” theory, which suggests that alcohol does not provoke any specific affect, it merely weakens executive control. This research, we argue, lends support to a deontic moral psychology, which identifies our ability to suppress behavioral impulses as a central feature of moral agency.     

Interaction between the DRD4 VNTR polymorphism and proximal and distal environments in alcohol dependence during emerging and young adulthood

The manifestation of alcohol dependence at different developmental stages may be associated with different genetic and environmental factors. Taking a developmental approach, we characterized interaction between the dopamine receptor 4 variable number tandem repeat (DRD4 VNTR) polymorphism and developmentally specific environmental factors (childhood adversity, college/Greek organization involvement, and delayed adult role transition) on alcohol dependence during emerging and young adulthood. Prospective data were obtained from a cohort of 234 White individuals (56% women, 44% men) who were followed up at ages 18 through 34. A longitudinal hierarchical factor model was estimated to model a traitlike persistent alcohol dependence factor throughout emerging and young adulthood and 2 residual statelike alcohol dependence factors limited to emerging adulthood and young adulthood, respectively. We accounted for those alcohol dependence factors by modeling 3 two-way interaction effects between the DRD4 VNTR polymorphism and the 3 developmentally specific environment factors. Carriers of the DRD4 long allele showed greater susceptibility to environmental effects; they showed more persistent symptoms of alcohol dependence as childhood adversity increased and more alcohol dependence symptoms limited to emerging adulthood as college/Greek organization involvement increased. Alcohol dependence among noncarriers of the long allele, however, did not differ as a function of those environments. Although replication is necessary, these findings highlight the importance of repeated phenotypic assessments across development and modeling both distal and proximal environments and their interaction with genetic susceptibility at specific developmental stages.     

The visuomotor mental rotation task: visuomotor transformation times are reduced for small and perceptually familiar angles

In the visuomotor mental rotation (VMR) task, participants point to a location that deviates from a visual cue by a predetermined angle. This task elicits longer reaction times (RT) relative to tasks wherein the visual cue is spatially compatible with the movement goal. The authors previously reported that visuomotor transformations are faster and more efficient when VMR responses elicit a degree of dimensional overlap (i.e., 0° and 5°) or when the transformation involves a perceptually familiar angle (i.e., 90° or 180°; K. A. Neely & M. Heath, 2010b). One caveat to this finding is that standard and VMR responses were completed in separate blocks of trials. Thus, between-task differences not only reflect the temporal demands of the visuomotor transformations, but also reflect the temporal cost of response inhibition. The goal of this study was to isolate the time cost of visuomotor transformations in the VMR task. The results demonstrated that visuomotor transformations are more efficient and effective when the response entails a degree of dimensional overlap between target and response (i.e., when the angular disparity between the responses is small) or when the transformation angle is perceptually familiar.     

An investigation of the social identity model of collective action and the 'sedative' effect of intergroup contact among Black and White students in South Africa

Two studies investigated the role of intergroup contact in predicting collective action tendencies along with three key predictors proposed by the social identity model of collective action (SIMCA; Van Zomeren, Postmes, & Spears, 2008). Study 1 (N= 488 Black South African students) tested whether social identity would positively, whereas intergroup contact would negatively predict collective action and support for policies benefiting the ingroup. Study 2 (N= 244 White South African students) predicted whether social identity would positively predict collective action benefiting the ingroup, and intergroup contact would positively predict support for policies to benefit the Black outgroup. Both studies yielded evidence in support of the predictive power of social identity and contact on collective action and policy support. Additionally, Study 1 confirmed that intergroup contact moderated the effects of social identity on relative deprivation, and relative deprivation on collective action. Overall findings support an integration of SIMCA and intergroup contact theory, and provide a fuller understanding of the social psychological processes leading to collective action.     

Risk for suicidal thoughts and behavior after childhood sexual abuse in women and men

Earlier studies have found an elevated risk for psychopathology and suicidal behavior associated with childhood sexual abuse (CSA); however, the degree to which risk is mediated by depression and posttraumatic stress disorder (PTSD) in women and men remains unclear. We examined these issues in data from a family study of childhood maltreatment (N = 2,559). We found significant CSA-associated risk for depression, PTSD, and suicidal behavior for women and men. In survival analyses controlling for these disorders, we observed persistent but somewhat reduced CSA-associated risk for suicidal ideation and suicide attempt. Our findings suggest that these disorders partially mediate CSA-associated risk.     

Nonsuicidal self-injury and gender: patterns of prevalence, methods, and locations among adolescents

Nonsuicidal self-injury (NSSI) among adolescents is a growing concern. However, little is known about gender and features of this behavior. Gender differences in NSSI among a sample of 7,126 adolescents were investigated, 1,774 of whom reported having engaged in NSSI. Gender differences in prevalence, method, and location of NSSI were examined. Findings revealed that females reported higher rates of NSSI, more cutting and scratching, and more injuries to arms and legs than their male counterparts. Males reported more burning and hitting-type behavior, as well as injuries to the chest, face, or genitals. This highlights an interesting pattern of NSSI, which future research should consider to accurately examine NSSI in females and males.     

Ezekiel Tragicus and Hellenistic Visuality: The Phoenix at Elim

The purpose of this article is to bring together discussionof Ezekiel Tragicus’ presentation of the Phoenix at Elimand modern scholarship on visuality, and thus also to pointto an area ripe for further research in the broader field ofstudy of the cultural interaction between Judaism and Hellenism.The Phoenix has most often been approached by way of traditionhistory. It is more true to the literary character of the scene,however, to examine it as a Hellenistic ecphrasis. Buildingon this observation, I draw into the discussion recent researchon the interface between literature and art as evidence forthe way people within a particular cultural setting use thesense of sight. This opens up the possibility of exploring Ezekiel'spresentation of the Phoenix at Elim as evidence for a hithertounexamined dimension of his cultural affinities. By comparingthe way he depicts the Phoenix chiefly with Graham Zanker'scareful study of Modes of Viewing in Hellenistic Poetry andArt (2003), it is argued that Ezekiel Tragicus had a distinctivelycontemporary and Hellenistic visual imagination.
