Negative Emotion Enhances Memory Accuracy: Behavioral and Neuroimaging Evidence

ABSTRACT— There have been extensive discussions about whether emotional memories contain more accurate detail than nonemotional memories do, or whether individuals simply believe that they have remembered emotional experiences more accurately. I review evidence that negative emotion enhances not only the subjective vividness of a memory but also the likelihood of remembering some (but not all) event details. I then describe neuroimaging evidence suggesting that engagement of emotion-processing regions (particularly the amygdala and orbitofrontal cortex) relates to the encoding and retrieval of details intrinsically linked to negative items.     

The impact of hope, self-esteem, and attributional style on adolescents’ school grades and emotional well-being: A longitudinal study

We examined the distinctiveness of three “positive thinking” variables (self-esteem, trait hope, and positive attributional style) in predicting future high school grades, teacher-rated adjustment, and students’ reports of their affective states. Seven hundred eighty-four high school students (382 males and 394 females; 8 did not indicate their gender) completed Time 1 measures of verbal and numerical ability, positive thinking, and indices of emotional well-being (positive affect, sadness, fear, and hostility), and Time 2 measures of hope, self-esteem, and emotional well-being. Multi-level random coefficient modelling revealed that each positive thinking variable was distinctive in some contexts but not others. Hope was a predictor of positive affect and the best predictor of grades, negative attributional style was the best predictor of increases in hostility and fear, and low self-esteem was the best predictor of increases in sadness. We also found that sadness at Time 1 predicted decreases in self-esteem at Time 2. The results are discussed with reference to the importance of positive thinking for building resilience.     

Sequence and priming in 15 month-olds' reactions to brief arm restraint: evidence for a hierarchy of anger responses

Brief, gentle arm restraint is widely used in experimental studies of children's anger, but the pattern of responses generated by such restraint has been incompletely described. We now describe a hierarchy of responses within trials as well as an escalation across trials that have both methodological and theoretical significance. Mothers of 87 15-month olds prevented them from playing with a toy by restraining their arms on two consecutive 30 sec trials. Physical struggling was the first and most frequent response; children who struggled were significantly more likely to vocalize, and those who vocalized were significantly more likely to show facial expressions of anger. The children's responses became more probable, rapid, and intense during Trial 2 restraint. Overall, the hierarchy was orderly enough to meet criteria for Guttman scalability. The particular sequence observed suggests situational, as opposed to bio-energetic, ordering of responses. Methodologically, the two trial paradigm is a simple, ecologically valid model for studying anger escalation that parallels the "attack priming" of aggression in other species. The magnitude and persistence of anger priming may provide novel measures of anger regulation. Theoretically, the existence of an orderly response hierarchy is consistent with previous observations suggesting that, within a situational context, the sequential appearance of specific behaviors may indicate progressive increases in anger intensity.     

Understanding the relationship between obesity and positive and negative affect: the role of psychosocial mechanisms

We examined the relationship between body mass index (BMI) and positive and negative affect, and evaluated whether this relationship is mediated (or suppressed) by physical health, intrusiveness of weight on physical functioning, and distressing interpersonal interactions. Analyses were based on a national sample of more than 3,000 adults ages 25 to 74. Class II (BMI 35–39.9) and Class III (BMI ≥ 40) obesity were associated with more frequent negative affect and less frequent positive affect, even after demographic and socioeconomic status characteristics were controlled. After the purported pathway variables were controlled, however, obese I persons reported significantly more frequent positive affect, while overweight, obese I, and obese II persons reported significantly less frequent negative affect, compared to normal weight persons. These patterns did not differ significantly by race or gender. Our findings suggest that excessive body weight is not necessarily distressing, yet the physical and interpersonal strains associated with obesity may impair one's mood. We discuss the implications for policy and practice.     

大学生生活满意度判断的文化差异研究

对36个国家8007名大学生的生活满意度进行了问卷调查。多层线性模型分析(HLM)的结果表明:(1)积极情感体验、自我满意和社会关系满意度能显著正向预测生活满意度,而消极情感体验能显著负向预测生活满意度;(2)情感体验、自尊和社会关系满意度对整体生活满意度的预测力存在着显著的国家间差异;(3)个人主义———集体主义是导致生活满意度水平国家间差异的重要因素,同时也对自尊与生活满意度的相关有显著预测作用,但它并不影响情感体验和社会关系满意度与整体生活满意度之间的关系。     

Mindfulness and psychological well-being among black South African university students and their relatives

This study investigated the relationship between mindfulness and psychological well-being in a convenience sample of black South African students (n = 203) and their parents and other relatives (n = 204) (66.1% = female; age range 18–73). The students self-reported on their mindfulness on the Mindful Attention Awareness Scale and psychological well-being on the Satisfaction with Life Scale, the Positive and Negative Affect Schedule, Adult Trait Hope Scale and the Meaning in Life Questionnaire. A multivariate regression model was specified and analysed via structural equation modelling in Mplus 7.3. Results revealed that mindfulness scores strongly predicted elevated levels of meaning and positive affect, and lowered levels of negative effect, and were moderately strong predictors of life satisfaction and hope. The findings imply that mindfulness likely plays an important role in relation to the psychological well-being of cross-generational African culture community members.

Feeling happy and (over)confident: the role of positive affect in metacognitive processes

The relationship between affect and metacognitive processes has been largely overlooked in both the affect and the metacognition literatures. While at the core of many affect-cognition theories is the notion that positive affective states lead people to be more confident, few studies systematically investigated how positive affect influences confidence and strategic behaviour. In two experiments, when participants were free to control answer interval to general knowledge questions (e.g. question: “in what year”, answer: “it was between 1970 and 1985”), participants induced with positive affect outperformed participants in a neutral affect condition. However, in Experiment 1 positive affect participants showed larger overconfidence than neutral affect participants. In Experiment 2, enhanced salience of social cues eliminated this overconfidence disadvantage of positive affect relative to neutral affect participants, without compromising their enhanced performance. Notably, in both experiments, positive affect led to compromised social norms regarding the answers’ informativeness. Implications for both affect and metacognition are discussed.     

Consistency in maternal affect and positive vocalization over the first year of life

Consistency in parenting infants has positive developmental outcomes. Yet, the role of socioeconomic status (SES) in consistency of maternal behaviors is not well understood. We investigated individual-order continuity of maternal smile and laughter and positive vocalization from 6 to 12 months of age in 82 mother-infant dyads. Overall, individual differences in maternal smile and laughter, and positive vocalization were consistent across time. A multidimensional measure of SES moderated the association of maternal smile and laughter from 6 to 12 months, such that infants from lower SES families were vulnerable to unpredictable parenting - experiencing a lack of consistency in maternal smiles and laughter.     

Exploring the psychometric properties of the CES-D-10 and its practicality in detecting depressive symptomatology in 27 low- and middle-income countries

The Center for Epidemiological Studies Depression-10 (CES-D-10) scale is known for its good psychometric properties in measuring depressive symptoms, however, some researchers question its applicability across various settings. This study explored the factor structure of the CES-D-10 in low- and middle-income countries (LMICs). This cross-sectional survey consisted of 16,723 university students across 27 LMICs that completed self-report instruments assessing socio-demographic information and depressive symptoms using the CES-D-10. Data analysis included: exploratory factor analysis, item response theory and differential item functioning. Results indicate that a two-factor model (depressive affect and positive affect) had the best fit for this population and accounted for 52% of the total observed variance with an internal consistency, α = .77 for the depressive affect items and α = .57 for the positive affect items. The graded response model (GRM), however, indicated that the depressive affect factor had a good fit, unlike the positive affect factor. The depressive affect factor was found to consistently model depression for females better than males. Relative to their Asian counterparts, African, Caribbean and South American participants of similar depressive affect responded differently on all items of the depressive affect factor. The depressive affect factor seems most ideal for LMICs and shows gender and cross-cultural variability.
