Impact of individual differences upon emotion-induced memory trade-offs

After seeing a scene containing an emotional component (e.g., a snake in a forest) people often demonstrate a “trade-off” in memory, where memory for the emotional component (e.g., the snake) is good, but memory for the non-emotional elements (e.g., the forest) is poor. The result is an incomplete memory retaining central emotional information at the expense of neutral background information. Though almost everyone demonstrates the trade-off, there may be individual differences in the magnitude of the effect. We investigated whether differences in the strength of the trade-off would correlate with anxiety levels, working memory capacity, and executive functioning abilities. Sixty-four participants studied scenes comprised of a negative or neutral item placed on a neutral background, and memory was later tested for items and backgrounds separately. The magnitude of the trade-off correlated positively with anxiety and negatively with visuospatial working memory and executive function. These results suggest that greater anxiety, poor visuospatial working memory, and poor executive function may inhibit formation of complete mental representations of these complex emotional scenes.     

Memory for the 2008 presidential election in healthy ageing and mild cognitive impairment

The present study examined memory accuracy and confidence for personal and public event details of the 2008 presidential election in healthy older adults and those with mild cognitive impairment (MCI). Participants completed phone interviews within a week after the election and after a 10-month delay. MCI patients and healthy older adults had comparable emotional reactions to learning the outcome of the election, with most people finding it to be a positive experience. After the delay period, details about the election were better remembered by all participants than a less emotionally arousing comparison event. However, MCI patients had more difficulty than healthy older adults correctly recalling details of public information about the election, although often the MCI patients could recognise the correct details. This is the first study to show that MCI patients' memory can benefit from emotionally arousing positive events, complementing the literature demonstrating similar effects for negative events.     

Mental state decoding in past major depression: Effect of sad versus happy mood induction

Individuals with mild depression show an enhanced ability to read or “decode” others' mental states. The goal of the present study was to investigate whether this pattern of performance is related specifically to the pathology of depression or whether it is simply a feature of the transient dysphoric state. Forty-one undergraduates with a previous episode of major depression and 52 undergraduates with no depression history participated in a mental state decoding task following a sad versus happy mood induction. Previously depressed participants were significantly more accurate in their mental state judgements than were the never-depressed participants, suggesting that enhanced mental state decoding may be a specific feature of depression in remission. Furthermore, previously depressed participants whose positive mood increased in response to the happy mood induction showed a poorer level of performance on the task, similar to that observed in the never-depressed group. Thus, a happy mood may have induced a somewhat less accurate, but perhaps more adaptive, approach to processing social information. These findings were robust after controlling for current level of depression and anxiety symptoms, intensity of response to the mood induction, response times, and performance on a control task.     

Validity Concerns in the Measurement of Women’s and Men’s Report of Intimate Partner Violence

The measurement of intimate partner violence (IPV) has proven to be more complex than originally anticipated and content and construct validity need to be greatly improved for IPV assessment. For measurement of IPV in the United States, these validity issues range from providing the most accurate wording for the content domain to controversies as to when violent actions are counted (e.g., self-defense) or whether to include mild aggression (e.g., psychological conflict tactics) that may be more normative and not harmful. The three major forms of IPV (i.e., physical, sexual, and psychological abuse) have distinct validity issues and may require different modalities for assessment. Gender needs to be considered when establishing construct validity due to differences in the meaning of aggression, impacts of abuse, and even patterns of violence for women and men. External threats to validity include potential bias of self-report and motivations when reporting on a partner, discrepancies in couples’ reports, the influence of response styles, and design issues affecting reporting. Traditional methods used to establish validity for IPV scales are reviewed and critiqued. Recommendations for enhancing validity in IPV assessment are provided.     

Development of a Unified Protocol for the Treatment of Emotional Disorders in Youth

This study evaluated the efficacy of the Mind Reading interactive computer software to remediate emotion recognition deficits in children with autism spectrum disorders (ASD). Six unmedicated children with ASD and 11 unmedicated non-clinical control subjects participated in the study. The clinical sample used the software for five sessions. The control sample was evaluated only on pre- and post-test performance to assess practice effects. Results showed that participants with ASD scored significantly higher on the posttest than on the pretest. As level of emotion difficulty increased, mean scores on the pretest decreased, indicating that difficulty level had a valid effect. The Mind Reading computer software appears to significantly improve the emotion recognition abilities in children with ASD.     

Providing information about diagnostic features at retrieval reduces false recognition

In the following study, participants encoded blocked DRM word lists and we varied whether they received information before test about the utility of mnemonic features that potentially discriminate between veridical and false memories. The results of three experiments revealed that this manipulation successfully reduced false recognition of critical theme words. We also found that this manipulation was effective for younger but not older adults. Furthermore, calling attention to the features in test instructions alone was sufficient for reducing false recognition and its effectiveness was not enhanced by also asking participants to rate their phenomenal experience. We argue that providing diagnostic information before test allows participants to establish more accurate expectations about the task and thus improves the efficacy of retrieval and monitoring processes that are subsequently engaged.     

Perceptions of Socially Disadvantaged Children: A Personal Construct Approach

The current study compares the perceptions of self, family, and the world of runaway, abandoned, and home-living children using a personal construct approach. The sample consisted of 28 institutionalized runaway children (22 boys and six girls), 40 abandoned children (20 boys and 20 girls), and 50 home-living children (25 boys and 25 girls). The research tools included a semistructured demographic interview, a sentence completion test, and repertory grid technique. Results indicated that runaway children perceived their fathers as more rejecting and unloving as compared to abandoned and home-living children. Friends were construed positively by runaway children as opposed to home-living and abandoned children. On the domain of self, it was found that all the three groups were confused and unsure of their self-concept. Results of the study indicate that runaway children experience a substantial degree of pull toward the external world or other people, and the family was found to be pushing the child into the world of the unknown.     

Dual n-back training increases the capacity of the focus of attention

Working memory (WM) training has been reported to benefit abilities as diverse as fluid intelligence (Jaeggi et al., Proceedings of the National Academy of Sciences of the United States of America, 105:6829–6833, 2008) and reading comprehension (Chein & Morrison, Psychonomic Bulletin & Review, 17:193–199, 2010), but transfer is not always observed (for reviews, see Morrison & Chein, Psychonomics Bulletin & Review, 18:46–60, 2011; Shipstead et al., Psychological Bulletin, 138:628–654, 2012). In contrast, recent WM training studies have consistently reported improvement on the trained tasks. The basis for these training benefits has received little attention, however, and it is not known which WM components and/or processes are being improved. Therefore, the goal of the present study was to investigate five possible mechanisms underlying the effects of adaptive dual n-back training on working memory (i.e., improvements in executive attention, updating, and focus switching, as well as increases in the capacity of the focus of attention and short-term memory). In addition to a no-contact control group, the present study also included an active control group whose members received nonadaptive training on the same task. All three groups showed significant improvements on the n-back task from pretest to posttest, but adaptive training produced larger improvements than did nonadaptive training, which in turn produced larger improvements than simply retesting. Adaptive, but not nonadaptive, training also resulted in improvements on an untrained running span task that measured the capacity of the focus of attention. No other differential improvements were observed, suggesting that increases in the capacity of the focus of attention underlie the benefits of adaptive dual n-back training.     

Influence of value predispositions,interpersonal contact,and mediated exposure on public attitudes toward homosexuals in Singapore

This national survey tracks changes in Singaporeans' attitudes toward lesbians and gay men (ATLG) and examines value predispositions, interpersonal contact, and mediated exposure as predictors of ATLG and acceptance of homosexuals. The study replicates and extends research done previously and addresses temporal shifts in values and views. Findings indicate that the relatively small positive change in ATLG from 2005 to 2010 was mainly due to values and demographic factors. The addition of several new predictive variables increased the variance explained for why people hold certain ATLG and their acceptance. Conformity to norms, intrinsic religiosity, Western orientation, interpersonal contact, and mediated exposure were significantly associated with both ATLG and acceptance of homosexuals. Perception of homosexuality as a choice was significantly associated with ATLG but not with acceptance of homosexuals. Asian orientation and extrinsic religiosity showed no significant association with either dependent variable. The findings are discussed in the context of a multicultural Asian society and future directions for research.     

Interpretive Artists: A Qualitative Exploration of the Creative Process of Actors

Actors, dancers, and musicians generally are referred to as artists, but many do not originate the work they perform; rather, they interpret the work of originating artists. Past models of the creative process were based on originating artists. The purpose of this study was to explore the creative process of interpretive artists, specifically actors. To further characterize the creative process of actors, this study additionally investigated (a) the social influences that undermined or enhanced an actor's creativity, (b) the tension that occurs between an actor's personal and character identities, and (c) the need for spontaneity in the creative process of actors. Semistructured interviews were conducted with 3 actors. Content analysis revealed three stages of the creative process for actors: a general preparation period, rehearsal, and performance. This model was compared with a previous model of the creative process based on originating artists. Social influences seen as enhancing creativity were clear direction, trust, freedom, respect, challenge, collaboration, and unity with the audience. Undermining social influences included reward, poor direction, evaluation, distrust, peers who stopped listening, and feeling interchangeable. The tension between an actor's personal and character identities was characterized by catharsis and difficulty in delineating boundaries. The need for spontaneity was seen as crucial in the actor's creative process. It is suggested that the actor's creative process is more improvisational, characterized by process and product co-occurring, real-time social influences, tension between personal and performing identities, and the need for spontaneity.
