Affect and between-meal snacking in daily life: the moderating role of gender and age

Objective: Affect-related energy intake from snacks remains relatively unexplored in daily life. This study examines the associations between momentary positive affect (PA) and momentary negative affect (NA) and subsequent energy intake from snacks. In addition, the moderating role of BMI, gender, age and level of education is investigated.

Design: Adults (N = 269), aged 20–50, participated in this study. Demographics were assessed in an online composite questionnaire. An experience sampling smartphone application was used to map momentary NA/PA and energy intake (kilocalories) from snacks in the context of daily life.

Main outcome measures: Energy intake from moment-to-moment self-reported snacks in real-life settings.

Results: A significant negative main effect of momentary NA on moment-to-moment energy intake was found. The higher the momentary NA, the lower the subsequent amount of kilocalories consumed. There was no main effect with regard to PA. Interaction analyses showed that men decreased their energy intake after experiencing NA, and increased their intake after experiencing PA. No associations were found in women. Additionally, young adults (20–30) increased their energy intake after experiencing PA. No associations were found in the other age groups.

Conclusion: Interventions aiming at reducing energy intake might also address PA-related snacking in young adults and men.     

Assessing the Initial Pleasantness for Fading Affect,Fixed Affect,Flourishing Affect,and Flexible Affect Events

Over time, autobiographical memories demonstrate fixed affect (i.e., maintain initial affect), fading affect, flourishing affect (i.e., increased affect), or flexible affect (i.e., change from unpleasant to pleasant or vice versa). Walker and Skowronski argued that events low in initial pleasantness are more likely to exhibit flourishing affect and flexible affect and that unpleasant events are more likely to demonstrate flexible affect than pleasant events. However, because of the low frequency of flourishing affect and flexible affect events in individual studies, research had not examined differences between these event categories. The present study examined initial pleasantness ratings for fading affect, fixed affect, flourishing affect, and flexible affect events across four published studies. We expected and generally found lower initial pleasantness for flourishing affect and flexible affect events than for fading affect and fixed affect events. Implications are discussed.

积极情感消极情感量表（PANAS）的修订

以情感二维结构理论为基础,对Watson等（1988）编制的积极情感消极情感量表（PANAS）进行了修订。收集了几种主要的情感环丛模型中积极情感和消极情感项目后,用专家评定法剔除了不属于情绪描述词的项目,并用问卷法考察了这些情感体验的典型性,试测后确定了积极情感和消极情感项目各9项构成最终量表。最后用自评、同伴评价和认知测量法对量表的心理测量学属性进行了较为全面的分析。结果表明,修订后的PANAS中各项目具有良好的区分度,是情感幸福感有效和可靠的测量工具。     

Affect and Cognition

ABSTRACT— One of the greatest puzzles of human nature concerns the poorly understood interplay between affect and cognition—the rational and emotional ways of dealing with the social world around us. Affect is a ubiquitous and powerful phenomenon in our lives, yet research on human affectivity has been neglected until quite recently. This article reviews traditional and contemporary approaches to this issue, and recent theoretical and empirical work exploring the links between affect and cognition is considered. The major achievements and shortcomings of this now-thriving research area are discussed, and the future prospects of psychological research on human affectivity are considered.     

Age Differences in Perceived Positive Affect, Negative Affect, and Affect Balance in Middle and Old Age

Meta-analysis was used to synthesize findings from 125 studies on age differences in positive affect, negative affect, and affect balance. We found a small age-associated decline of positive affect and affect balance, and a small age-associated increase of negative affect. In addition, a quadratic age trend emerged, showing stronger declines of positive affect and stronger increases of negative affect in older subjects. Looking at changes of specific emotions, we found an age-associated decline of those positive and negative feelings that are associated with high arousal (e.g., feeling excited or upset), and an age-associated increase of positive and negative low-arousal emotions (e.g., feeling relaxed or depressed). Furthermore, older adults from the former communist Eastern European countries showed the strongest age-associated decline of positive affect and the strongest age-associated increase of negative affect. We conclude that age-associated losses in the oldest old and economic hardship make the optimization of subjective well-being increasingly difficult.     

Affect and sensation seeking

The notion that affective responses differentiate high from low sensation-seekers was investigated. Male subjects with extremely high (N=13) or low (N=13) scores on Form V of the Sensation Seeking Scale (SSS) were presented with tones of 60, 80, and 100 dB in successive blocks of 10 tones each. Although measures of arousal (verbal self-reports and physiological measures of the orienting response) did not differentiate between high and low sensation-seekers, a self-report measure of pleasure did: Whereas reported pleasure of the low sensation-seekers began high and declined as tones became successively louder, the reported pleasure of the high sensation-seekers remained more constant across the blocks of tones.The research on which this paper was based was supported by Grant MT-4511 from the Medical Research Council of Canada to Robert Hare.     

Risk Perception and Affect

ABSTRACT— Humans perceive and act on risk in two fundamental ways. Risk as feelings refers to individuals' instinctive and intuitive reactions to danger. Risk as analysis brings logic, reason, and scientific deliberation to bear on risk management. Reliance on risk as feelings is described as "the affect heuristic." This article traces the development of this heuristic and discusses some of the important ways that it impacts how people perceive and evaluate risk.     

Spotlight on Affect: Affect and Affective Forecasting in Impulse Control

The authors propose an alternative conceptualization to the Strack, Werth, and Deutsch (2006) model. This alternative conceptualization considers how the forecasting of emotional outcomes linked to controlling or failing to control impulses affects self‐regulatory behavior. A set of future research questions is identified based on this conceptualization. The proposed model differs from that of Strack et al. (2006) by its focus on (a) affect, (b) impulse control (versus buying), and (c) deliberative processing linked to impulse control (or lack thereof).     

Positive Affect and Health

ABSTRACT— Negative affective styles such as anxiety, depression, and hostility have long been accepted as predictors of increased risk for illness and mortality. In contrast, positive affective styles have been relatively ignored in the health literature. Here we highlight consistent patterns of research associating trait positive affect (PA) and physical health. The evidence we review suggests an association of trait PA and lower morbidity and decreased symptoms and pain. PA is also associated with increased longevity among community-dwelling elderly. The association of PA and survival among those with serious illness is less clear and suggests the possibility that PA may be harmful in some situations. We conclude by raising conceptual and methodological reservations about this literature and suggesting directions for future research.     

Affect and the computer game player: the effect of gender, personality, and game reinforcement structure on affective responses to computer game-play.

Previous research on computer games has tended to concentrate on their more negative effects (e.g., addiction, increased aggression). This study departs from the traditional clinical and social learning explanations for these behavioral phenomena and examines the effect of personality, in-game reinforcement characteristics, gender, and skill on the emotional state of the game-player. Results demonstrated that in-game reinforcement characteristics and skill significantly effect a number of affective measures (most notably excitement and frustration). The implications of the impact of game-play on affect are discussed with reference to the concepts of "addiction" and "aggression."     

Positive Affect and College Success

This study investigated the relation between positive affect and a variety of variables related to college success for undergraduate students matriculating at 21 academically selective 4-year colleges and universities in the United States. Positive affect??cheerfulness??is generally positively related to students?? self-rated academic abilities, self-predicted likelihoods of various college outcomes, self-stated major and academic-degree intentions, and self-reported subjective college outcomes, but negatively related to most objective college-success variables (e.g., cumulative college grade-point average) recorded by the institution of matriculation, and not related to objective college outcomes reported by the student. Positive affect is thus associated with ??positive illusions?? about college-success variables.     

Affect and automatic mood maintenance

The hedonic contingency model (HCM; Wegener & Petty, 1994) states that individuals have learned to seek out positive activities while in a happy mood in order to maintain or elevate that mood. We argue that this tendency may become overlearned and, thus, automated. More specifically, the experience of a happy mood was predicted to automatically activate the mood-maintenance tendency proposed by the HCM. Participants induced into happy, sad, or neutral moods ranked their preferences for future activities that were nonconsciously associated with either a positive or negative valence. Supporting the notion of automatic mood maintenance, happy participants appeared to evaluate the affective qualities of the future activities and base their preferences on this evaluation without realizing that they were doing so. Theoretical implications of this finding are discussed.     

Affect and delay of gratification

Three experiments investigated the influence of positive and negative affect manipulations on children's preferences for small immediate versus large delayed rewards. Positive and negative affect were induced via verbal instructions to imagine happy and sad experiences. Elementary school children were randomly assigned to a control condition or to one of several treatment conditions consisting of two affect manipulations: a positive followed by a negative, the reverse, and (in the third experiment) two positives or two negatives. In some conditions (in the second and third experiments) measurement of delayed reward preference followed the first and second affect inductions whereas in other conditions (in the second and third experiments) measurement followed only the second affect manipulation. As predicted, negative affect subjects chose fewer large delayed rewards than did positive affect subjects during the first assessment (p < .02). At the second assessment, comparison among treatment and control conditions revealed the influence of a prior commitment effect which negated the potential influence of a second affect manipulation on preference for delayed rewards.     

The impact of competition on intrinsic motivation and creativity: considering gender, gender segregation and gender role orientation

The present research investigated whether competition influences children's artistic creativity and intrinsic motivation toward an art activity. Study 1 tested the hypothesis that boys' creativity would be enhanced by competition, while girls' creativity would be undermined. Fifty children (aged 6–10) made paper collages in one of two conditions; half competed for prizes and half did not. Results supported our hypotheses, and further showed that when children self-segregated by gender, the impact of competition was much more pronounced. Study 2 was designed to clarify the unexpected gender-segregation finding from Study 1. The Children's Sex Role Inventory [Boldizar, J.P. (1991). Assessing sex typing and androgyny in children: the Children's Sex Role Inventory. Developmental Psychology, 27, 505–515] was administered to 143 children (aged 6–11). One week later, these children made paper collages in one of four conditions; in addition to manipulating competition, assigned seating ensured that half of children were segregated by gender and half were not. Following the collage activity, an intrinsic and extrinsic motivation questionnaire was administered. Masculine children reported higher levels of intrinsic motivation when competing and when segregated by gender; they also reported higher levels of extrinsic motivation, especially when segregated by gender. These findings demonstrate that gender role is an important factor in determining children's responses to competition.     

Social isolation and gender

This study investigated the relationship between gender and social support. It was found that men were more isolated than women although there were no gender differences in perceived adequacy (i.e., satisfaction with one's social support network) or network size. Given that both the adequacy and network size variables were associated with socially desirable responding but the isolation variable was not, the results suggest that the behaviorally oriented indicator of isolation was a better measure of the degree of social isolation than traditional subjective scales currently used by many researchers. This suggests that traditional measures of social support that incorporate the dimensions of network size and perceived adequacy of one's social support system need to control for socially desirable responding and that measures can and need to be developed that are not significantly influenced by this response set bias. Hence, the assessment of social support may need to be more multifaceted than is currently undertaken in many studies. Our finding that men reported being more isolated than women may be a function, in part, of the fact that the majority of the sample (76.7%) was single/did not live with a partner. Previous research has found that men generally get their emotional needs met by their spouses/partners while women often get their emotional needs met by their female friends. Consistent with the literature, and given that most of our respondents were single, this study supports the contention that men are generally more socially isolated than women because they do not create adequate emotional intimacy when they are not in partnership with a significant other.
