Updating misconceptions: Effects of age and confidence

Young adults are more likely to correct an initial higher confidence error than a lower confidence error (Butterfield & Metcalfe, 2001). This hypercorrection effect has never been investigated among older adults, although features of the standard paradigm (free recall, metacognitive judgments) and prior evidence of age-related error resolution deficits (see Clare & Jones, 2008) suggest that they may not show this effect. In Study 1, we used free recall and a 7-point confidence scale; in Study 2, we used multiple-choice questions, and participants indicated how many alternatives they had narrowed their options down to prior to answering. In both studies, younger and older adults showed a hypercorrection effect, and this effect was equivalent between groups in Study 2 when free recall and explicit confidence ratings were not required. These results are consistent with our previous work (Cyr & Anderson, 2012) showing that older adults can successfully resolve learning errors when the learning context provides sufficient support.     

Parts function as perceptual organizational entities in infancy

Both objects and parts function as organizational entities in adult perception. Prior research has indicated that objects affect organization early in life: Infants grouped elements located within object boundaries and segregated them from those located on different objects. Here, we examined whether parts also induce grouping in infancy. Five- and 6.5-month-olds were habituated to two-part objects containing element pairs. In a subsequent test, infants treated groupings of elements that crossed part boundaries as novel, in comparison with groupings that had shared a common part during habituation. In contrast, the same arrangement of elements failed to elicit evidence of grouping in control conditions in which the elements were not surrounded by closed part boundaries. Thus, infants grouped and segregated elements on the basis of part structure. Part-based processing is a key aspect of many theories of perception. The present research adds to this literature by indicating that parts function as organizational entities early in life.     

Do You See What I See? The Influence of Gender Stereotypes on Student and Royal Canadian Mounted Police (RCMP) Perceptions of Violent Same-Sex and Opposite-Sex Relationships

ABSTRACT

Forty-one men and 67 women undergraduate students, as well as 35 men and 27 women Royal Canadian Mounted Police (RCMP) officers, rated the abusiveness of intimate partner violence (IPV) vignettes portraying each possible gender combination of victim and perpetrator (Harris &; Cook, 1994 Harris, R. J. and Cook, C. A. 1994. Attributions about spouse abuse: It matters who the batterers and victims are. Sex Roles, 30: 553–565. [Crossref], [Web of Science ®] , [Google Scholar]). Rating differences according to victim and perpetrator gender, occupation (student or RCMP officer), and participant gender were anticipated. Analyses found that student and RCMP ratings of abuse severity were both highest for the male-female scenario. However, the RCMP considered the female-male, male-male, and female-female scenarios to be more abusive than did the students. Our findings suggest that, while the RCMP appeared to be more sensitive to male and same-sex victims than students, both groups remain somewhat biased.     

The Role of PTSD and Length of Shelter Stay in Battered Women's Severity of Reabuse after Leaving Shelter

Intimate partner violence (IPV) is associated with significant morbidity, including high rates of reabuse even after women have taken steps to achieve safety. This study evaluated the roles of posttraumatic stress disorder (PTSD) symptom severity and length of shelter stay in the severity of reabuse in 103 IPV victims over a six-month period after leaving a battered women's shelter. Results suggest that the length of shelter stay is inversely related to reabuse severity after leaving shelter. Additionally, more severe PTSD symptoms on shelter exit were associated with greater reabuse severity after leaving shelter. Furthermore, additional study findings support prior research suggesting that the emotional numbing symptoms of PTSD are a significant risk factor for reabuse among IPV victims after leaving shelter.     

Childhood Maltreatment and PTSD: Spiritual Well-Being and Intimate Partner Violence as Mediators

Childhood maltreatment places individuals, including African American women who are undereducated and economically disadvantaged, at risk for developing posttraumatic stress disorder (PTSD) symptoms. Participants were 192 African American women with a history in the prior year of both a suicide attempt and intimate partner violence (IPV) exposure. They were recruited from a public hospital that provides medical and mental health treatment to mostly low-income patients. A simple mediator model was used to examine if (a) existential well-being (sense of purpose) or religious well-being (relationship with God) mediated the link between childhood maltreatment and adult PTSD symptoms. Sequential multiple mediator models determined if physical and nonphysical IPV enhanced our understanding of the mediational association among the aforementioned variables. Findings suggest that existential well-being mediated the association between childhood maltreatment and adult PTSD symptoms in a simple mediator model, and existential well-being and recent nonphysical IPV served as sequential multiple mediators of this link. However, religious well-being and physical IPV were not significant mediators. Findings underscore the importance of enhancing existential well-being in the treatment of suicidal African American women with a history of childhood maltreatment and IPV.     

Assessing research on workplace violence, 2000–2012

Since the highly publicized U.S. Postal violence cases in the 1980s, workplace aggression and workplace violence have been the source of much public discussion and concern. Yet, the topic has only recently received sustained empirical attention—most of which has come from the organizational management and business fields. This article provides a review of the empirical research literature on workplace violence in several databases from 2000 to 2012. Our review uncovers that different occupational domains have different experiences with workplace violence, while some occupations are subject to distinct types of violence by unique aggressors. Directions for future theoretical and empirical research are highlighted.     

Haunted by somatic tendencies: Spirit infestation as psychogenic illness

It has been suggested that haunting and poltergeist episodes are akin to outbreaks of contagious psychogenic illness. Therefore, it might be expected that hypochondriacal and somatic tendencies would significantly predict self-reported experiences of 'spirit infestation' and other paranormal ideations. This prediction was tested on a sample of 314 undergraduate students who completed the Anomalous Experiences Inventory, the Transliminality Scale and three standard questionnaires about hypochondriasis, somatic complaints, and cognitions about body and health. Results from correlational and regression analyses supported predictions, although we found that the type of bodily cognition varied with the specificity of the paranormal experience. For example, indices of spirit infestation coincided with autonomic sensations, perceived paranormal ability was related to catastrophizing cognitions, and general paranormal experiences correlated with somatization traits. Transliminality and paranormal belief contributed positively to nearly all of these associations. These findings are consistent with the idea that some paranormal experiences are partly misattributions of internal experience to external (paranormal) sources - a process that could initiate an episode of contagious (mass) psychogenic illness by encouraging the collective perception of similar 'symptoms' in a group of people due to suggestion and demand characteristics.     

Blame,desert and compatibilist capacity: a diachronic account of moderateness in regards to reasons-responsiveness

This paper argues that John Fischer and Mark Ravizza's compatibilist theory of moral responsibility cannot justify reactive attitudes like blame and desert-based practices like retributive punishment. The problem with their account, I argue, is that their analysis of moderateness in regards to reasons-responsiveness has the wrong normative features. However, I propose an alternative account of what it means for a mechanism to be moderately reasons-responsive which addresses this deficiency. In a nut shell, while Fischer and Ravizza test for moderate reasons-responsiveness by checking how a mechanism behaves in a given time slice across other possible worlds, on my account we should ask how that mechanism behaves in this world over a span of time – specifically, whether it responds to reasons sufficiently often. My diachronic account is intended as a drop-in replacement for Fischer and Ravizza's synchronic account.     

A comparison of visual and auditory representational momentum in spatial tasks

Similarities have been observed in the localization of the final position of moving visual and moving auditory stimuli: Perceived endpoints that are judged to be farther in the direction of motion in both modalities likely reflect extrapolation of the trajectory, mediated by predictive mechanisms at higher cognitive levels. However, actual comparisons of the magnitudes of displacement between visual tasks and auditory tasks using the same experimental setup are rare. As such, the purpose of the present free-field study was to investigate the influences of the spatial location of motion offset, stimulus velocity, and motion direction on the localization of the final positions of moving auditory stimuli (Experiment 1 and 2) and moving visual stimuli (Experiment 3). To assess whether auditory performance is affected by dynamically changing binaural cues that are used for the localization of moving auditory stimuli (interaural time differences for low-frequency sounds and interaural intensity differences for high-frequency sounds), two distinct noise bands were employed in Experiments 1 and 2. In all three experiments, less precise encoding of spatial coordinates in paralateral space resulted in larger forward displacements, but this effect was drowned out by the underestimation of target eccentricity in the extreme periphery. Furthermore, our results revealed clear differences between visual and auditory tasks. Displacements in the visual task were dependent on velocity and the spatial location of the final position, but an additional influence of motion direction was observed in the auditory tasks. Together, these findings indicate that the modality-specific processing of motion parameters affects the extrapolation of the trajectory.     

Self-Presentation Concerns and Health Behaviors Among Cosmetic Surgery Patients

The present investigation examined the relationship between self-presentational motives and physical activity in a population of cosmetic surgery participants. Participants were 50 female and 5 male cosmetic surgery patients (CSPs; M age = 38.5 years) who completed a battery of self-report measures following either vein or acne treatment. Analyses revealed significant group differences on self-presentational concern and public self-consciousness between: (a) those who elected the treatment for appearance motives and those who elected treatment for health-based motives, and (b) the more frequent (3 or more times per week) and less frequent (2 or less times per week) exercisers. Greater self-presentational concerns and greater public self-consciousness were associated with having appearance-related motives for treatment and with being a less frequent exerciser.
