Beliefs about personality change and continuity

Lay conceptions of personality change and continuity were examined in a sample of 112 undergraduates. Participants rated their personal change over 5 years (past or future), the change they perceived to be normative over 10-year age spans between 15 and 65, their beliefs about whether personality is fixed or malleable (“lay theories”) and their beliefs about the causes of personality change and continuity. Beliefs about normative personality change generally corresponded to research evidence on adult trajectories of the Big Five factors, with some age bias, whereas recalled and anticipated personal change tended to be more positive than these norms. Participants tended to endorse environmental causes more for personality change than for continuity. Lay theories were not consistently associated with these causal beliefs, or with beliefs about personal and normative change.     

Untangling the Links between Narcissism and Self‐esteem: A Theoretical and Empirical Review

The links among narcissism, explicit (deliberate, controllable) self‐esteem, and implicit (automatic, uncontrollable) self‐esteem are unclear despite numerous attempts to illuminate these links. Some investigations suggest that narcissism reflects high explicit self‐esteem that masks low implicit self‐esteem, but other investigations fail to replicate this pattern. Here, we place the ‘mask’ model of narcissism in historical context and review the existing empirical evidence for this model. We then discuss three possible issues that might shed light on the inconsistent findings that have emerged from tests of the mask model. These issues include the unreliability of implicit attitude measures, narcissism's different associations with agentic versus communal self‐views, and distinctions between grandiose and vulnerable narcissism subtypes. We also summarize several alternatives to the mask model of narcissism. Throughout, we offer suggestions for improving the study of narcissism and self‐esteem and point to directions for future research on this topic.     

Lifecourse Social Conditions and Racial and Ethnic Patterns of Cognitive Aging

A lifecourse perspective is key for understanding and interpreting racial and ethnic patterns in neuropsychological test performance. In this article, we discuss contextual factors that shape the environmental conditions encountered by racial and ethnic minorities in the United States, in particular African-Americans. These conditions include geographic segregation at the level of regions, metropolitan areas, and neighborhoods; intra- and inter-national migration patterns; socioeconomic position, including financial resources, and occupational and educational opportunities; discrimination; and group resources. Each of these exposures sets in course a cascade of individual mediators that ultimately manifest in neuropsychological outcomes. The physiological and behavioral consequences of these pathways likely accumulate across the lifecourse. We focus on cognitive aging, although the processes discussed here begin in infancy and likely influence cognitive outcomes throughout life from childhood into old age. A lifecourse framework can help inform clinical encounters, neuropsychological research, and surveillance regarding the population prevalence of cognitive impairments.     

The role of social meaning in inattentional blindness: When the gorillas in our midst do not go unseen

Without visual attention, even the obvious–like a gorilla walking through a scene of people–goes undetected (Mack & Rock, 1998; Simons & Chabris, 1999). This “inattentional blindness” is a persistent, well-documented limitation of the human visual system. The current research examines whether social meaning reduces this visual bias by imbuing unexpected objects with signal value, thus increasing their relevance and facilitating perception. Using one of the most established illustrations of inattentional blindness, we show for the first time that activating a social association, even an erroneous one (i.e., the African American–ape association), drastically attenuates inattentional blindness. This is not accounted for by visual feature matching. Rather, these results suggest that social meaning, even when flawed, may direct our visual system towards associated visual information that would otherwise be overlooked. As such, these results provide a powerful replication of the African American–ape association and illustrate that this broadly held association has the power to spontaneously change the content of one's visual world.     

The effect of the psychopathy checklist – revised in capital cases: Mock jurors' responses to the label of psychopathy

Despite mixed empirical evidence regarding the ability of the Psychopathy Checklist – Revised (PCL‐R) to predict violence among incarcerated inmates, it continues to be used to address such questions, even in the context of capital cases. The purpose of this study was to examine if the PCL‐R has a prejudicial effect on mock jury members during the sentencing phase of a capital murder trial. Results indicated that participants were more likely to sentence the defendant to death when the defendant exhibited a high likelihood to commit future violence, whether or not the diagnostic label “psychopath” was present. Interestingly, when asked to rate the defendant's likelihood for future violence and murder, the defendant who was a high risk for future violence and not labeled a psychopath received the highest rating. These results suggest an absence of juror bias as it pertains to the label “psychopath” when sentencing a defendant in a capital murder case. Copyright © 2010 John Wiley & Sons, Ltd.     

Optimizing retrieval as a learning event: When and why expanding retrieval practice enhances long-term retention

Retrieving information from memory makes that information more recallable in the future than it otherwise would have been. Optimizing retrieval practice has been assumed, on the basis of evidence and arguments tracing back to Landauer and Bjork (1978), to require an expanding-interval schedule of successive retrievals, but recent findings suggest that expanding retrieval practice may be inferior to uniform-interval retrieval practice when memory is tested after a long retention interval. We report three experiments in which participants read educational passages and were then repeatedly tested, without feedback, after an expanding or uniform sequence of intervals. On a test 1 week later, recall was enhanced by the expanding schedule, but only when the task between successive retrievals was highly interfering with memory for the passage. These results suggest that the extent to which learners benefit from expanding retrieval practice depends on the degree to which the to-belearned information is vulnerable to forgetting.     

Positive affectivity and lifestyle in adulthood: do you do what you feel?

There is much evidence for the adaptive value of positive affect. Empirical work examining different facets of positive affect and their consequences for psychological adaptation remains sparse, however. This study (young, middle-aged, and older adults; N = 293) investigated the links between two dimensions of positive affect (positive involvement and pleasant affect) and two lifestyles (hedonic and growth related), each indicated by general value orientations, self-reported everyday activities, and activity aspirations. Structural equation models showed that pleasant affect and positive involvement constitute distinct dimensions evincing different age trends and relating differentially to hedonic and growth-related lifestyles. Specifically, pleasant affect, but not positive involvement, was related to a hedonic lifestyle, whereas positive involvement, and not pleasant affect, was associated with a growth-related lifestyle. These findings underline the importance of considering two dimensions of positive affect--pleasant feelings and positive involvement--separately when studying the link between affect and lifestyle.     

Aging and the perception of biological motion

Two experiments examined how observers' ability to perceive biological motion changes with increasing age. The observers discriminated among kinetic figures, depicting walking, jogging, and skipping. The direction, duration, and temporal correspondence of the motions were manipulated. Quantitative differences occurred between the recognition performances of younger and older observers, but these differences were often modest. The older and younger observers' performances were comparable for most conditions at stimulus durations of 400 ms. The older observers also performed well above chance at shorter durations of 240 and 120 ms. Unlike their performance on other 2- or 3-dimensional motion tasks, older observers' ability to perceive biological motion is relatively well preserved.     

Leader Positive Mood and Group Performance: The Case of Customer Service

It was hypothesized that leader positive mood would be positively associated with group performance in a service setting. Additionally, it was expected that while leader positive mood would be positively associated with both the leader's level of job satisfaction and job involvement, leader positive mood would be positively associated with group performance, controlling for both leader job satisfaction and job involvement. Leader positive mood also was expected to be positively associated with group performance controlling for group positive affective tone. Two potential antecedents of leader positive mood, the leader's level of positive affectivity and the extent to which the leader's own manager engaged in contingent reward behavior, were hypothesized to be positively associated with leader positive mood at work. These hypotheses were tested among a sample of 53 sales managers who led groups ranging in size from 4 to 9 members. All of the hypotheses were supported. Implications of these results and directions for future research are discussed.
