A bias to detail: how hand position modulates visual learning and visual memory

In this report, we examine whether and how altered aspects of perception and attention near the hands affect one’s learning of to-be-remembered visual material. We employed the contextual cuing paradigm of visual learning in two experiments. Participants searched for a target embedded within images of fractals and other complex geometrical patterns while either holding their hands near to or far from the stimuli. When visual features and structural patterns remained constant across to-be-learned images (Exp. 1), no difference emerged between hand postures in the observed rates of learning. However, when to-be-learned scenes maintained structural pattern information but changed in color (Exp. 2), participants exhibited substantially slower rates of learning when holding their hands near the material. This finding shows that learning near the hands is impaired in situations in which common information must be abstracted from visually unique images, suggesting a bias toward detail-oriented processing near the hands.     

Attachment and relationship satisfaction in expectant first-time parents: The mediating role of relationship enhancing behaviors

Individual differences in attachment are well established as a correlate of couple relationship satisfaction. However, less is known about the role of attachment in predicting satisfaction at specific milestone points in couple relationships. The present study explored the role of attachment in predicting relationship satisfaction during couples’ first pregnancy, and the mediating role of relationship enhancing behaviors. Male and female attachment anxiety and avoidance predicted their own low relationship satisfaction, and this was partially mediated by relationship enhancing behaviors. Male attachment anxiety and avoidance predicted low female satisfaction, and this was fully mediated by relationship enhancing behaviors. This study is the first to highlight the important role of male attachment during pregnancy, and the mediating role of relationship enhancing behaviors.     

Locus of control as a contributing factor in the relation between self-perception and adolescent aggression

Researchers continue to debate the role of self-esteem in aggression, but research has shown a consistent association between narcissism and aggression in adults and adolescents [e.g., Barry et al., 2007; Bushman and Baumeister, 1998; Stucke, 2007]. The primary aim of the current study was to examine whether locus of control (LOC) moderated the relation between self-perception variables (i.e., self-esteem and narcissism) and aggression in adolescents. Participants were 174 youth (145 males, 26 females) between the ages of 16 and 19 who were enrolled in a voluntary residential program for youth who have dropped out of school. The results showed that LOC moderated the association between self-esteem and aggression such that low self-esteem was associated with higher levels of aggression for individuals with an external LOC. Contrary to expectations, LOC failed to moderate the narcissism-aggression relation. The implications of this study for understanding how self-perception is related to adolescent aggression are discussed.     

The role of cue-response mapping in motorvisual impairment and facilitation: evidence for different roles of action planning and action control in motorvisual dual-task priming

Previous research has shown that actions impair the visual perception of categorically action-consistent stimuli. On the other hand, actions can also facilitate the perception of spatially action-consistent stimuli. We suggest that motorvisual impairment is due to action planning processes, while motorvisual facilitation is due to action control mechanisms. This implies that because action planning is sensitive to modulations by cue-response mapping so should motorvisual impairment, while motorvisual facilitation should be insensitive to manipulations of cue-response mapping as is action control. We tested this prediction in three dual-task experiments. The impact of performing left and right key presses on the perception of unrelated, categorically or spatially consistent, stimuli was studied. As expected, we found motorvisual impairment for categorically consistent stimuli and motorvisual facilitation for spatially consistent stimuli. In all experiments, we compared congruent with incongruent cue-key mappings. Mapping manipulations affected motorvisual impairment, but not motorvisual facilitation. The results support our suggestion that motorvisual impairment is due to action planning, and motorvisual facilitation to action control.     

Costs and benefits in hunter-gatherer punishment

Hunter-gatherer punishment involves costs and benefits to individuals and groups, but the costs do not necessarily fit with the assumptions made in models that consider punishment to be altruistic--which brings in the free-rider problem and the problem of second-order free-riders. In this commentary, I present foragers' capital punishment patterns ethnographically, in the interest of establishing whether such punishment is likely to be costly; and I suggest that in many cases abstentions from punishment that might be taken as defections by free-riders are actually caused by social-structural considerations rather than being an effect of free-rider genes. This presentation of data supplements the ethnographic analysis provided by Guala.     

Social Issues,Authoritarianism, and Ideological Conceptualization: How Policy Dimensions and Psychological Factors Influence Ideological Labeling

Ideology's crucial theoretical and empirical role in explaining political behavior makes it imperative that scholars understand how individuals conceptualize and apply ideological labels. The existing literature on this topic is quite limited, however, because it relies almost exclusively upon data from the 1970s and 1980s, and it does not examine how psychological factors influence conceptualizations of ideological labels. This article uses data from two original laboratory experiments to test the relative impact of four major policy dimensions on participants' evaluations of candidate ideology and to test authoritarianism's role in shaping ideological conceptualization. These analyses indicate that individuals most often define liberalism and conservatism primarily in terms of social policies closely associated with religious values, each of which invert traditional ideological orientations toward the appropriate size and role of government. The causal mechanism shaping this relationship is authoritarianism, because, I argue, the religious social policy dimension most clearly evokes the deep‐seated value conflicts associated with an authoritarian view of political conflict.     

Unified protocol for transdiagnostic treatment of emotional disorders: a randomized controlled trial

This study further evaluates the efficacy of the Unified Protocol for Transdiagnostic Treatment of Emotional Disorders (UP). A diagnostically heterogeneous clinical sample of 37 patients with a principal anxiety disorder diagnosis was enrolled in a randomized controlled trial (RCT) involving up to 18 sessions of treatment and a 6-month follow-up period. Patients were randomly assigned to receive either immediate treatment with the UP (n=26) or delayed treatment, following a 16-week wait-list control period (WLC; n=11). The UP resulted in significant improvement on measures of clinical severity, general symptoms of depression and anxiety, levels of negative and positive affect, and a measure of symptom interference in daily functioning across diagnoses. In comparison, participants in the WLC condition exhibited little to no change following the 16-week wait-list period. The effects of UP treatment were maintained over the 6-month follow-up period. Results from this RCT provide additional evidence for the efficacy of the UP in the treatment of anxiety and comorbid depressive disorders, and provide additional support for a transdiagnostic approach to the treatment of emotional disorders.
