Forgetting in context: The effects of age, emotion, and social factors on retrieval-induced forgetting

Retrieval-induced forgetting (RIF) refers to the finding that selectively retrieving some information impairs subsequent memory for related but nonretrieved information. This occurs both for the individual doing the remembering (i.e., within-individual retrieval-induced forgetting: WI-RIF), as well as for individuals merely listening to those recollections (i.e., socially shared retrieval-induced forgetting: SS-RIF). In the present study, we examined how the contextual factors of age and emotion independently and interactively affect both WI-RIF and SS-RIF. The results indicated that both WI-RIF and SS-RIF occurred at equivalent levels, both for younger and older adults and for neutral and emotional information. However, we identified a boundary condition to this effect: People only exhibited SS-RIF when the speaker that they were listening to was of the same sex as themselves. Given that participants reported feeling closer to same-sex speakers, this suggests that people co-retrieve more, and therefore exhibit increased SS-RIF, with close others. In everyday life, these RIF effects should influence what information is remembered versus forgotten in individual and collective memories.     

When a new group identity does harm on the spot: Stereotype threat in newly created groups

The detrimental consequences of negative stereotypes on performance have been demonstrated in a variety of social groups with various stereotypes. The present studies investigate the minimal conditions for stereotype threat using newly created groups. Results of three experiments (total N = 184) demonstrate that in the negative stereotype condition, the more participants identified with their novel group, the stronger was their decrease in performance. In the control condition, identification was either not related to performance, or it had by trend a positive effect. The theoretical and practical implications of the findings are discussed with regard to stereotype threat and social identity theory. Copyright © 2011 John Wiley & Sons, Ltd.     

Social comparisons in novel situations: finding inspiration during life transitions

The authors propose that individuals transitioning to a novel environment will prefer upward comparisons, particularly those made with individuals who have experienced a similar transition. Such comparisons help to reduce uncertainty and demonstrate that future success is possible. Study 1 found that individuals facing transitions to unfamiliar situations seek upward comparisons as a result of their uncertainty. Study 2 demonstrated that individuals who perceive themselves to be making a significant life transition are especially motivated by upward comparisons. Study 3 provided evidence that upward comparisons are especially inspiring to individuals making a transition to a novel cultural environment. Study 4 provided experimental evidence that individuals in a novel cultural environment are particularly inspired by upward comparisons with other newcomers. These studies suggest that upward comparisons with individuals who have experienced a similar transition enhance individuals' sense of control over future outcomes and play a key role during adjustment to novel environments.     

Effect of viewing plane on perceived distances in real and virtual environments

Three experiments examined perceived absolute distance in a head-mounted display virtual environment (HMD-VE) and a matched real-world environment, as a function of the type and orientation of the distance viewed. In Experiment 1, participants turned and walked, without vision, a distance to match the viewed interval for both egocentric (viewer-to-target) and exocentric (target-to-target) extents. Egocentric distances were underestimated in the HMD-VE while exocentric distances were estimated similarly across environments. Since egocentric distances were displayed in the depth plane and exocentric distances in the frontal plane, the pattern of results could have been related to the orientation of the distance or to the type of distance. Experiments 2 and 3 tested these alternatives. Participants estimated exocentric distances presented along the depth or frontal plane either by turning and walking (Experiment 2) or by turning and throwing a beanbag to indicate the perceived extent (Experiment 3). For both Experiments 2 and 3, depth intervals were underestimated in the HMD-VE compared to the real world. However, frontal intervals were estimated similarly across environments. The findings suggest anisotropy in HMD-VE distance perception such that distance underestimation in the HMD-VE generalizes to intervals in the depth plane, but not to intervals in the frontal plane.

The fast and the dangerous: the speed of events influences risk judgements

A risk-as-feelings approach suggests that factors irrelevant to the potential risk can influence risk perception. This investigation focused on the speed of events as one such factor. Negative events that occur relatively quickly were judged as more likely to occur than events that occur more slowly. Speed influenced risk perception when it was salient and differences in risk perception were reduced when it was not salient. Further, the likelihood of a negative outcome was judged to be more likely when the same event was described as occurring relatively quickly compared to slowly. Even when only the speed at which information was presented changed, faster events were judged to be riskier than slower events. Theoretically, these findings suggest that speed of an event contributes to risk judgements and suggest speed may be the reason people fear fast but low incidence events and fail to fear slower but higher incidence events.     

When does random responding distort self-report personality assessment? An example with the NEO PI-R

Recent meta-analyses suggest that, notwithstanding almost 100 years of study, concerns about the impact of response biases on the validity of self-report personality scales remain to be justified. This study addresses the topic by demonstrating that random responding is indeed an issue for self-report personality scales, and that limitations associated with base rates exist that affect the ability of moderated multiple regression to evaluate fully the effects of a response bias. Overall, it is suggested that dismissing response biases as a concern for self-report personality assessment is premature when based only on a lack of significant regression moderator effects.     

“It Depends on What You Mean by ‘Disagree’”: Differences between Parent and Child Perceptions of Parent–Child Conflict

We examined a new structured interview of parent?Cchild conflict that assesses parent and child perceptions of behavioral conflict about daily life topics (e.g., doing chores, homework), and whether discrepancies exist on beliefs about these topics. In a sample of 100 parents and children ages 10 to 17?years (M?=?13.5?years, 52 males, 57?% African-American), informants could reliably distinguish between perceived behavioral conflicts and perceived discrepant beliefs about topics. These scores were also significantly related to questionnaire reports of parent?Cchild conflict. Parent and child questionnaire reports did not significantly differ, yet on the structured interview, parents reported significantly greater levels of perceived conflict and discrepant beliefs relative to child reports. Additionally, structured interview reports of conflict demonstrated incremental validity by relating to child self-reports of delinquent behaviors, when accounting for questionnaire conflict reports. The findings have implications for increasing understanding of the links between parent?Cchild conflict and psychosocial outcomes.     

Adolescent Self-Reports of Social Anxiety: Can They Disagree with Objective Psychophysiological Measures and Still Be Valid?

We examined self-reported and parent-reported adolescent social anxiety symptoms and objective baseline measures of psychophysiological flexibility in 62 families. Measures completed by 31 adolescents referred for a clinical screening evaluation for social anxiety were compared to an age- and gender-matched community control sample of 31 adolescents (total sample: age range 14 to 17?years; 22 boys and 40 girls; M?=?15.32?years; SD?=?1.1). Clinic referred adolescents reported significantly fewer social anxiety symptoms than parents reported about adolescents. Further, for all adolescents, self-reported social anxiety symptoms exhibited low correspondence with objective psychophysiological measures. Yet, both measures uniquely discriminated between adolescents on whether they were clinic referred for a social anxiety screening. Further, adolescent self-reported social anxiety symptoms exhibited high levels of internal consistency and convergent validity. Findings indicate that researchers and practitioners should refrain from using disagreements between adolescent self-reports and other measures (e.g., parent report, objective measures) as indicators of the veracity of adolescent self-reports.     

Social Discounting and Cigarette Smoking During Pregnancy

In this study, we examined the association between social discounting and smoking status in a cohort of pregnant cigarette smokers (n = 91), quitters (n = 27), or never‐smokers (n = 30). The smokers and quitters were participants in clinical trials on smoking cessation and relapse prevention, whereas the never‐smokers were controls in a study on nicotine withdrawal during pregnancy. Social discounting was assessed using a paper‐and‐pencil task that assesses the amount of hypothetical money a person is willing to forgo in order to share with individuals in their social network ranging from the person who is emotionally closest to them to a mere acquaintance. The amount that women were willing to forgo in order to share decreased hyperbolically as a function of social distance, with smokers exhibiting steeper discounting functions (i.e., less generosity) than quitters or never‐smokers; discounting functions of quitters and never‐smokers did not differ significantly. In multivariate analyses controlling for potential sociodemographic and other confounds, social discounting remained a significant predictor of smoking status among smokers versus quitters. Overall, these results suggest that individual differences in social discounting may be a factor influencing the choices that women make about quitting smoking upon learning of a pregnancy.

The neurodevelopmental basis of math anxiety

Math anxiety is a negative emotional reaction to situations involving mathematical problem solving. Math anxiety has a detrimental impact on an individual's long-term professional success, but its neurodevelopmental origins are unknown. In a functional MRI study on 7- to 9-year-old children, we showed that math anxiety was associated with hyperactivity in right amygdala regions that are important for processing negative emotions. In addition, we found that math anxiety was associated with reduced activity in posterior parietal and dorsolateral prefrontal cortex regions involved in mathematical reasoning. Multivariate classification analysis revealed distinct multivoxel activity patterns, which were independent of overall activation levels in the right amygdala. Furthermore, effective connectivity between the amygdala and ventromedial prefrontal cortex regions that regulate negative emotions was elevated in children with math anxiety. These effects were specific to math anxiety and unrelated to general anxiety, intelligence, working memory, or reading ability. Our study identified the neural correlates of math anxiety for the first time, and our findings have significant implications for its early identification and treatment.
