The Self‐enhancement Function of Autobiographical Memory

The self‐enhancement function of autobiographical memory was examined by assessing the psychological distance of adults' most important memories. Participants (N = 445, ages 18–80) reported the seven most important events from their lives on an online survey and rated the memories in terms of valence, emotionality, importance, vividness, reliving, rehearsal, novelty, and psychological distance. Participants also completed the Rosenberg Self‐esteem Scale. Regression analyses showed that participants felt psychologically closer to positive memories than to negative memories, independent of the actual age of the memories. The self‐enhancement function was unrelated to participants' age but was related to their self‐esteem: Higher self‐esteem was associated with feeling closer to positive memories. Finally, a moderated multiple‐mediation model showed that memories' importance and rehearsal mediated the relation between one's self‐esteem and the psychological distance of their positive versus negative memories. Findings are discussed in relation to the functional approach to autobiographical memory. Copyright © 2014 John Wiley & Sons, Ltd.

A meta-analysis of response-time tests of the sequential two-systems model of moral judgment

The (generalized) sequential two-system (“default interventionist”) model of utilitarian moral judgment predicts that utilitarian responses often arise from a system-two correction of system-one deontological intuitions. Response-time (RT) results that seem to support this model are usually explained by the fact that low-probability responses have longer RTs. Following earlier results, we predicted response probability from each subject’s tendency to make utilitarian responses (A, “Ability”) and each dilemma’s tendency to elicit deontological responses (D, “Difficulty”), estimated from a Rasch model. At the point where A = D, the two responses are equally likely, so probability effects cannot account for any RT differences between them. The sequential two-system model still predicts that many of the utilitarian responses made at this point will result from system-two corrections of system-one intuitions, hence should take longer. However, when A = D, RT for the two responses was the same, contradicting the sequential model. Here we report a meta-analysis of 26 data sets, which replicated the earlier results of no RT difference overall at the point where A = D. The data sets used three different kinds of moral judgment items, and the RT equality at the point where A = D held for all three. In addition, we found that RT increased with A–D. This result holds for subjects (characterized by Ability) but not for items (characterized by Difficulty). We explain the main features of this unanticipated effect, and of the main results, with a drift-diffusion model.     

Hydrothermal growth of ZnO nanoparticles under different conditions

In this study, a simple low-temperature hydrothermal method was used to synthesize ZnO nanoparticles. The structural, morphological and optical characterizations of the nanoparticles were evaluated with regard to the zinc content. To achieve this, the molar ratios of the precursors were changed from 0.05 to 0.1 M. The structural and morphological analyses showed that all samples had a polycrystalline hexangular wurtzite crystal structure and the shape of the ZnO nanoparticles changed with increasing zinc content. A possible growth mechanism of the ZnO nanoparticles is explained in terms of the zinc content. Optical measurement revealed that the shape of the nanoparticles affects the position of the band-edge emission as well as the shape of the luminescence spectrum.     

The Resilience of Structure Built Around the Predicate: Homesign Gesture Systems in Turkish and American Deaf Children

Deaf children whose hearing losses prevent them from accessing spoken language and whose hearing parents have not exposed them to sign language develop gesture systems, called homesigns, which have many of the properties of natural language—the so-called resilient properties of language. We explored the resilience of structure built around the predicate—in particular, how manner and path are mapped onto the verb—in homesign systems developed by deaf children in Turkey and the United States. We also asked whether the Turkish homesigners exhibit sentence-level structures previously identified as resilient in American and Chinese homesigners. We found that the Turkish and American deaf children used not only the same production probability and ordering patterns to indicate who does what to whom, but also used the same segmentation and conflation patterns to package manner and path. The gestures that the hearing parents produced did not, for the most part, display the patterns found in the children's gestures. Although cospeech gesture may provide the building blocks for homesign, it does not provide the blueprint for these resilient properties of language.

The Power of Social Influence on Estimation Accuracy

Research shows that crowds can provide more accurate estimates of uncertain quantities than individuals (Surowiecki, 2004). But little is known about how to organize crowd members to maximize accuracy. When should crowd members work independently, and when should they work collaboratively? We examined the effects of social influence on estimation accuracy, consensus, and confidence. Participants first made independent estimates of uncertain quantities, such as the percentage of U.S. deaths due to heart attacks or the height of the tallest building. Then, in some conditions, they interacted with others online. After the discussion, they made second independent estimates. Social interaction improved accuracy. Despite well‐known problems with groups, such as herding and free riding, discussion resulted in more accurate estimates and greater consensus relative to independent estimates. We offer a simple model that describes the process by which group discussion improves the estimates of uncertain quantities. Copyright © 2014 John Wiley & Sons, Ltd.     

Autobiographical memory functions in young Japanese men and women

The present study examined whether the three major functions of autobiographical memory observed in Western societies (i.e., directing-behaviour, social-bonding and self-continuity) also exist in an East Asian society. Two self-report measures were used to assess the autobiographical memory functions of Japanese men and women. Japanese young adults (N = 451, ages 17–28 years) first completed the original Thinking About Life Experiences (TALE) Questionnaire. They subsequently received three TALE items that represented memory functions and attempted to recall a specific instance of memory recall for each item. Confirmatory factor analyses on the TALE showed that the three functions were replicated in the current sample. However, Japanese participants reported lower levels of all three functions than American participants in a previous study. We also explored whether there was an effect of gender in this Japanese sample. Women reported higher levels of the self-continuity and social-bonding functions than men. Finally, participants recalled more specific instances of memory recall for the TALE items that had received higher ratings on the TALE, suggesting that the findings on the first measure were supported by the second measure. Results are discussed in relation to the functional approach to autobiographical memory in a cross-cultural context.     

Examining the life story account of the reminiscence bump: Why we remember more from young adulthood

The reminiscence bump is a robust finding demonstrated mostly with the cue-word method in Western cultures. The first aim of the study was to replicate the reminiscence bump using a life history timeline method and to extend reminiscence bump research to a Turkish sample. The second aim was to empirically examine the recently proposed life story account (Glück & Bluck, 2007) for the reminiscence bump. The sample consisted of 40 women and 32 men aged 52 to 66 years. Participants’ lives were divided into 5-year intervals and they verbally reported as many memories as possible in a standard timeframe from each interval (in random order) and provided ratings of several memory characteristics. As expected, the lifespan distribution of the resulting 6373 memories demonstrated a reminiscence bump. In support of the life story account, bump memories were found to be more novel, more important for identity development, more distinct, and more likely to involve developmental transitions than memories from other age periods. Findings are discussed in terms of the life story account, which synthesises lifespan developmental theory and life story theory.     

Acting Superior But Actually Inferior?: Correlates and Consequences of Workplace Arrogance

Accounts of arrogant employees abound, yet there is little systematic research on arrogance within organizations. In response to this oversight, this article presents the findings from four studies. In Studies 1 and 2, the authors developed the Workplace Arrogance Scale and found support for its convergent and discriminant validity. In Study 3, the Workplace Arrogance Scale was included as part of a 360-degree performance feedback survey. Results revealed that there was satisfactory agreement between self- and other-ratings of arrogance. The authors also found that arrogance was negatively related to self- and other-rated task performance. Findings from Study 4 suggested that arrogance is negatively related to cognitive ability and self-esteem. The authors conclude by discussing the theoretical and practical implications of these findings.
