The first-perspective alignment effect: the role of environmental complexity and familiarity with surroundings

People often remember relatively novel environments from the first perspective encountered or the first direction of travel. This initial perspective can determine a preferred orientation that facilitates the efficiency of spatial judgements at multiple recalled locations. The present study examined this "first-perspective alignment effect" (FPA effect). In three experiments, university students explored three-path routes through computer-simulated spaces presented on a desktop computer screen. Spatial memory was then tested employing a "judgement of relative direction" task. Contrary to the predictions of a previous account, Experiment 1 found a reliable FPA effect in barren and complex environments. Experiment 2 strongly implicated the importance of complete novelty of the space surrounding the route in producing the effect. Experiment 3 found that, while familiarity with the surrounding space greatly attenuated the FPA effect with immediate testing, the effect reemerged following a 7-day delay to testing. The implications for the encoding and retrieval of spatial reference frames are discussed.     

The role of aesthetic sensitivity in body dysmorphic disorder

Individuals with a higher aesthetic sensitivity may be more vulnerable to developing body dysmorphic disorder (BDD). Aesthetic sensitivity has 3 components: (a) perceptual, (b) emotional, and (c) evaluative. Individuals with BDD (n = 50) were compared with a control group of individuals with an education or employment in art and design related fields (n = 50) and a control group of individuals without aesthetic training (n = 50). A facial photograph of each participant was manipulated to create a 9-image symmetry continuum. Presented with the continuum on a computer, participants were required to select and rate the image representing their self-actual, self-ideal, idea of perfect, most physically attractive, most pleasure, and most disgust. Control symmetry continua examined the specificity of the disturbance. As predicted, BDD participants displayed no distortion in their perceptual processing but were disturbed in their negative emotional/evaluative processing of their self-image. A significant discrepancy between their self-actual and self-ideal, resulting from an absent self-serving bias in their self-actual (a bias exhibited by controls) appears to be the source of their disturbance. They also overvalued the importance of appearance and self-objectified. These aesthetic evaluations may predispose individuals to BDD and/or maintain the disorder.     

Attachment orientations and depression: a longitudinal study of new parents

In this longitudinal study, we followed a large sample of first-time parents (both partners) across the first 2 years of the transition to parenthood. Guided by attachment theory (Bowlby, 1969), we tested several predictions about how attachment anxiety and avoidance are related to the incidence, maintenance, increase, and decline of depressive symptoms in both sexes across the first 2 years of the transition. We found that (a) the association between attachment anxiety and depressive symptoms was moderated by factors related to the marital and/or romantic relationship; (b) the association between avoidance and depressive symptoms was moderated by factors related to family responsibilities; (c) styles of caregiving provided by romantic partners affected depressive symptoms differently among anxious and avoidant persons; and (d) in certain predictable situations, depressive symptoms persisted at higher levels or increased to higher levels in anxious or avoidant persons across the 2-year transition period. Important implications of these results are discussed.     

De‐Centering and Re‐Centering: Rethinking Concepts and Methods in the Sociological Study of Religion

Four conceptual and methodological edges or areas of study are outlined. They are located near what have been the boundaries between the sociology of religion and other subfields, where we believe a potential exists to encourage a wide range of scholars to revisit some central concepts. Paying attention to these edges—as a means to de‐center to re‐center our debates in new ways—not only broadens and deepens our knowledge of the “religious,” it encourages us to reexamine long‐standing conceptual tools, unquestioned assumptions, and accepted methods in the sociology of religion. We illustrate these edges through a review of recent literature and examples drawn from our current empirical projects.     

The temporal distribution of autobiographical memory: changes in reliving and vividness over the life span do not explain the reminiscence bump

When autobiographical memories are elicited with word cues, personal events from middle childhood to early adulthood are overrepresented compared to events from other periods. It is, however, unclear whether these memories are also associated with greater recollection. In this online study, we examined whether autobiographical memories from adolescence and early adulthood are recollected more than memories from other lifetime periods. Participants rated personal events that were elicited with cue words on reliving or vividness. Consistent with previous studies, most memories came from the period in which the participants were between 6 and 20 years old. The memories from this period were not relived more or recalled more vividly than memories from other lifetime periods, suggesting that they do not involve more recollection. Recent events had higher levels of reliving and vividness than remote events, and older adults reported a stronger recollective experience than younger adults.     

Multiple contributions to priming effects for familiar faces: analyses with backward masking and event-related potentials

The model of face recognition by Bruce and Young postulates a pool of structural representations for familiar faces in long-term memory, so-called face recognition units (FRUs). Event-related brain potentials show early repetition priming effects for familiar faces around 250-300 ms [N250r or early repetition effect (ERE)], which are thought to reflect the activation of these FRUs. However, small N250r effects are also seen for unfamiliar faces suggesting that priming of perceptual codes (i.e., pictorial and structural codes) also contributes to early repetition effects. Using a face-familiarity task in Experiment 1, we aimed to eliminate these perceptual contributions to face priming by backward masking the prime face with a different, unfamiliar face. As expected, a repetition priming effect appeared only for familiar faces. Experiment 2 used a semantic-decision task and compared the effects of different kinds of masks that interfered with either pictorial codes or with pictorial and structural codes. Our findings indicate that both structural codes and memory representations contribute to the N250r and that unfamiliar-face masks interfere only with structural codes. Face-masks may therefore provide a useful tool to extract the pure contributions of memory representations (i.e., FRUs) to repetition priming.     

Attenuating memory distrust in a repeated checking task

Repeated checking has been demonstrated to lead to reductions in memory confidence in several previous studies using student and clinical samples. This process of reduced confidence in memory and detail for memory, are thought to arise from the inhibition of perceptual processing that develops during repeated checking. Our research investigated whether reduced memory confidence from repeated checking could be attenuated through the use of novel stimuli during the repeated checking task. Three groups were generated through random assignment of 65 undergraduate students. As seen in previous research, individuals who repeatedly checked a stimulus (a virtual stovetop) showed reduced memory confidence, vividness, and detail, when compared with individuals who repeatedly checked a different stimulus. A third group in which the colour of the repeatedly-checked stovetop changed every five trials showed no significant decline in memory confidence between the pre-test and post-test. Results suggest that increased memory distrust can be ameliorated through the use of stimuli with characteristics that are novel and distinctive. Findings are discussed in the context of the existing model of repeated checking and memory confidence, and implications for treatment methods are presented.     

Dissecting online control in Developmental Coordination Disorder: a kinematic analysis of double-step reaching

In a recent study, children with movement clumsiness (or Developmental Coordination Disorder-DCD) were shown to have difficulties making rapid online corrections when reaching, demonstrated by slower and less accurate movements to double-step targets (Hyde & Wilson, 2011). These results suggest that children with DCD have difficulty using predictive estimates of limb position when making rapid adjustments to movement, in-flight. However, chronometric data alone does not provide strong evidence for this hypothesis: it remains unclear whether early (and rapid) control parameters or post-correction stages of the movement trajectory are affected. Thus, the overarching aim of this study was to conduct a kinematic analysis of double-step reaching in order to isolate the different control parameters that might explain the slower and less accurate double-step reaching performance of children with DCD. Participants were a new sample of 13 children with DCD aged between 8-12 years and 13 age-matched controls. Children were required to reach and touch one of three possible targets presented at the coordinates -20°, 0° and 20° on a 17 in. LCD touch-screen. For most trials (80%) the target remained stationary for the duration of movement (non-jump trials), while for the remainder (20%), the target jumped randomly to one of two peripheral locations at movement onset (jump trials). Consistent with earlier work, children with DCD were slower to initiate reaching compared to controls and showed longer MT and more errors on jump trials. Kinematic data showed that while the two groups did not differ on time to peak velocity or acceleration, children with DCD were slower to correct reach trajectory on jump trials. No group differences were observed on late kinematic markers, e.g., post-correction time. The pattern of results support and extend earlier work showing deficits in ROC in DCD. From a computational perspective, delayed corrections to the reach trajectory suggests some difficulty integrating information about the target perturbation with a predictive (or forward) estimate of limb position relative to the initial target. These conclusions are discussed, along with directions for future research.     

The link between sensation seeking and aggression: a meta-analytic review

Substantial empirical evidence supports low resting heart rate (HR) as the best replicated psychophysiological correlate of aggression [Ortiz and Raine, 2004]; however, researchers continue to debate the explanatory mechanisms of the phenomenon. Sensation seeking has been proposed as a possible outcome of low resting HR that may lead to aggressive tendencies but findings have been inconsistent in terms of showing a relationship between sensation seeking and aggression. A meta-analysis was conducted on 43 independent effect sizes, from studies with a total of 32,217 participants, to test the hypothesis that sensation seeking would be positively related to aggression across studies. A significant overall effect size was found (d = .1935, P<.001), supporting the hypothesis. Moderator analyses revealed that the relationship differed based on participant and methodological characteristics, such as participant age and the nature of the aggression measurement; however, these conclusions are limited by the uneven number of studies in many of the moderator classes. Overall, the findings provide support for higher levels of aggression in high sensation seekers and have theoretical implications for arousal theory. Further research on the links between arousal, sensation seeking and aggression can inform clinicians about potential interventions.
