Negative affect as a predisposing factor for cortisol release after an acute stress--the impact of unpleasant priming

Glucocorticoids have a key role in stress responses. There are, however, substantial differences in cortisol reactivity among individuals. We investigated if affective trait and mood induction influence the reactivity to psychological stress in a group of 63 young adults, male (n=27) and female (n=36), aged ca. 21 years. On the experimental day the participants viewed either a block of pleasant or unpleasant pictures for 5 min to induce positive or negative mood, respectively. Then, they had 5 min to prepare a speech to be delivered in front of a video-camera. Saliva samples were collected to measure cortisol, and questionnaire-based affective scales were used to estimate emotional states and traits. Compared to basal levels, a cortisol response to the acute speech stressor was only seen for those who had first viewed unpleasant pictures and scored above the average on the negative affect scale. There were no sex differences. In conclusion, high negative affect associated with exposure to an unpleasant context increased sensitivity to an acute stressor, and was critical to stimulation of cortisol release by the speech stressor.     

Screen-based and non-screen-based sedentary behaviors are differentially associated with affective states in older adults

Excessive sedentary behavior (SB) contributes to poor affective and physical feeling states, which is particularly concerning for older adults who are the most sedentary sector of the population. Specific types of SB have been shown to differentially impact health in cross-sectional and longitudinal studies, with screen-based SB more negatively impacting aspects of mental health. This study used Ecological Momentary Assessment (EMA), a real-time, intensive longitudinal data capture methodology, to examine the differential impact of screen-based behaviors on momentary affective responses during SB in naturalistic settings. A diverse sample of older adults (pooled across 2 studies) completed an EMA protocol for 8–10 days with six randomly delivered, smartphone assessments per day. At each EMA prompt, participants reported their current activity, whether they were sitting while doing that activity, and affective states. Multilevel models assessed whether screen-based (vs. non-screen-based) behavior moderated affective response during SB.At the within-person level, older adults experienced less positive affect during SB when engaged in a screen-based behavior compared to a non-screen-based SB (B = −0.10, p < 0.01). At the between-person level, positive associations between SB and negative affect (B = 0.79, p = 0.03) were stronger if participants reported engaging in screen-based behaviors for a greater proportion of prompts. Among older adults, screen-based SB may lead to poorer affective states compared to non-screen-based SB. Interventions aiming to reduce SB in this population should consider targeting reductions in screen-based SB as means to improve affective states.     

The Impact of Positive and Negative Affect and Issue Framing on Issue Interpretation and Risk Taking

Two studies examined the influence of transient affective states and issue framing onissue interpretationandrisk takingwithin the context of strategic decision making. In Study 1, participants in whom transient positive or negative affective states were induced by reading a short story showed systematic differences in issue interpretation and risk taking in a strategic decision making context. Compared to negative mood participants, those in a positive mood were more likely to interpret the strategic issue as an opportunity and displayed lower levels of risk taking. Study 2 replicated and extended these results by crossing affective states with threat and opportunity frames. Results showed that framing an issue (as a threat or an opportunity) had a stronger impact on issue interpretation among negative affect participants than among positive affect participants. Affective states also moderated the impact of issue framing on risk taking: the effect of framing on risk-taking was stronger under negative rather than positive affect. These results are interpreted via information-processing and motivational effects of affect on a decision maker.     

The effects of worry and rumination on affect states and cognitive activity

The effects of worry and rumination on affective states and mentation type were examined in an unselected undergraduate sample in Study 1 and in a sample of individuals with high trait worry and rumination, high rumination, and low worry/rumination in Study 2. Participants engaged in worry and rumination inductions, counterbalanced in order across participants to assess main and interactive effects of these types of negative thinking. During mentation periods, the thought vs. imaginal nature and the temporal orientation of mentations were assessed 5 times. Following mentation periods, negative and positive affect, relaxation, anxiety, and depression were assessed. Both worry and rumination produced increases in negative affect and decreases in positive affect. Worry tended to generate greater anxiety, and rumination tended to generate greater depression. Interactive effects were also found indicating that worry may lessen the anxiety experienced during subsequent rumination. Moreover, worry lessened the depressing effects of rumination. Worry was associated with significantly greater thought than imagery, compared to rumination. Rumination involved a progression from mentation about the past to mentation about the future over time. Implications for understanding the generation of negative affect and comorbid anxiety and depression are discussed.     

Normal aging dampens the link between intrusive thoughts and negative affect in reaction to daily stressors

We charted daily variations in intrusive thoughts to gain access to adult age differences in affective reactivity to daily stressors. On 100 days, 101 younger and 103 older adults reported stressors, intrusive thoughts, and negative affect. Although increments in intrusive thoughts were similar in both age groups on days with stressors, older adults' negative affect increased less than younger adults' on such days. In addition, (a) levels of intrusive thoughts and negative affect across study time were positively associated; (b) days with increased thoughts were days with increased negative affect; and (c) experiencing above-average intrusive thoughts about stressors strengthened affective reactions to stress. Relative to younger adults, all three associations were reduced in older adults. We tentatively conclude that normal aging dampens the stress-induced link between intrusive thoughts and affect. This dampening may contribute to preserved affective well-being and reduced affective reactivity to daily stress in old age.     

The influence of aging on preferences for sequences of mixed affective events

Research on preferences among sequences of mixed affective events has mostly used young adults as participants. Given differences due to aging in people's ability to regulate emotion, one could expect differences due to aging in preferences for different sequences. Study 1 demonstrated age‐related differences in how older adults (age 65 and older) versus young adults (age 18–25) choose to order mixed affective events that will occur over time. The tendency to choose sequences in which the final event is positive was greater among older adults versus young adults. And, more so than young adults, older adults preferred that the positive and negative events in a sequence be separated in time by a neutral event. Studies 2–3 investigated age‐related differences in overall retrospective evaluations of presented sequences of mixed affective events. In contrast to young adults, older adults' retrospective evaluations were not affected by: (1) whether the final trend of the sequence improved monotonically; (2) whether the last event in the sequence was positive; or (3) the temporal proximity of positive and negative events in the sequence. Results of Study 3 suggest that these age‐related differences are due to differences in older (vs. young) adults' ability to regulate emotion. Copyright © 2010 John Wiley & Sons, Ltd.     

Age similarities in matching pro- and contra-hedonic emotional strategies to everyday scenarios

ABSTRACT

Older adults are motivated to maximize positive affect in the present. Young adults will purposely feel negative and high arousal emotions in order to achieve a goal. However, this type of contra-hedonic emotional alignment has not been extensively studied with older adults. We expected older adults are less likely than young adults to select high arousal and negative emotions within specific scenarios where those states could be useful. In two studies, participants selected the emotion they preferred in hypothetical problems that varied on the arousal and valence best suited for goal achievement. Young and older adults were equally likely to endorse affective strategies that matched both pro and contra-hedonic scenarios. While older adults may be generally motivated to avoid negative and high-arousing emotions, they are just as likely as young adults to indicate that these states could be helpful in certain situations.     

Using the Actor-Partner Interdependence Model to assess maternal and infant contributions to mother-infant affective exchanges during the Still-Face Paradigm

This study describes maternal and infant contributions to dyadic affective exchanges during the Still-Face Paradigm (SFP) in an understudied mostly low-income sample. One hundred eleven mothers and their 7-month-old infants were videotaped during the SFP to analyze how a social stressor affects mother-infant positive and negative affective exchanges during interaction. The SFP includes 3 episodes: baseline, maternal still-face, and reunion. Maternal and infant positive and negative affect were scored by masked reliable coders. Data were analyzed using the Actor-Partner Interdependence Model to test the hypotheses that each partner’s affectivity during the baseline episode would predict their own affectivity during the reunion episode (actor effects). We also expected that each partner’s affectivity during the baseline episode would influence the other partner’s affectivity during the reunion episodes (partner effects). After controlling for infant sex and maternal education, results provided evidence for actor effects for maternal and infant positive affect, and for partner effects for maternal baseline positive affect to infant positive affect during the reunion. One significant partner effect was observed for negative affect: Infant negativity during baseline predicted greater maternal negativity during reunion. Findings confirm that both mothers and infants contribute to dyadic affective processes during the SFP but specific findings vary depending on the affective valence in question. Clinical implications and future research are discussed.     

The effects of adult aging and induced positive and negative mood on planning

Changes in executive functions have been found in older adults and also in young adults experiencing positive or negative mood states. The current study investigated the hypothesis that older adults would show greater executive function impairment following mood induction than young adults. Ninety-six participants (half aged 19-37, half aged 53-80) completed a neutral, positive, or negative mood induction procedure, followed by the Tower of London planning task. Significant interactions were found between age and mood such that older adults showed greater planning impairment than young adults in both the positive and negative mood conditions. Emotionally salient events occurring before testing may interfere with executive function in older adults.     

Does mood state change risk taking tendency in older adults?

No study has been conducted to evaluate the influences of age differences on specific moods for risk taking tendencies. This study examined the patterns of risk taking tendencies among younger and older persons in 3 transient affective states: positive, neutral, and negative moods. By means of viewing happy, neutral, or sad movie clips, participants were induced to the respective mood. Risk taking tendencies were measured with decision tasks modified from the Choice Dilemmas Questionnaire (N. Kogan & M. A. Wallach, 1964). Consistent with the affect infusion model (J. P. Forgas, 1995), risk taking tendency was greater for those individuals who were in a happy mood than for those who were in a sad mood, for both young and older participants. However, an asymmetrical effect of positive and negative mood on risk taking tendency was identified among both the young and older participants, but in opposite directions. These results are consistent with the predictions of the negativity bias and the positivity effect found in young and older adults, respectively, and are interpreted via information processing and motivation effects of mood on the decision maker.     

Relation between self-reported affect and drug urges and cravings in continuing and withdrawing smokers.

In 2 experiments we investigated the effects of withdrawal and stress on the affective correlates of urges to smoke. In both, habitual cigarette smokers were divided into continuing and withdrawing smoker groups. In the 1st study, 44 adults reported current mood, urge, and expectations over a 24-hr period. In the 2nd, a controlled laboratory study, urge, affect, and physiological data were obtained from continuing and withdrawing groups (N = 64) exposed to high- or low-stress conditions. Urges among withdrawing smokers were positively associated with negative affect and negatively associated with positive affect; continuing smokers reported urges that were directly associated with positive affect and unrelated to negative affect. Stress and withdrawal produced urge self-reports that were related to negative affect. Moreover, subjects who smoked after exposure to withdrawal and stress reported greater pleasure and arousal than did other subjects.     

Choice of task and goal under conditions of general and specific affective inducement

In this study we examine the role of general and task-specific affect on task and goal choice in a performance setting. We use video stimuli to induce a general positive or general negative affective state, and use rate-of-progress and absolute discrepancy feedback to manipulate task-specific affect. Analyses indicate that general affective states influenced task and goal choices, self-efficacy expectations, and performance. Rate-of-progress feedback influenced affective state, task choice, and self-efficacy expectations. Absolute discrepancy feedback influenced task choice modestly and self-efficacy significantly. Generally, positive affect promoted mood maintenance while negative affect promoted mood repair, and general and task-specific affect exerted similar effects. Results are discussed in terms of the motivational consequences of affective states (either general or task-specific) for task and goal choices.     

Conflict monitoring and adaptation to affective stimuli as a function of ageing

The current study investigated whether preference for positive affect would be observed in the context of a higher order control process with increasing age given the premise of affective prioritization with ageing. The study examined how affect interacted with cognitive control mechanisms across young, middle-aged and older adults. Conflict monitoring and adaptation for affective stimuli was examined with a face-word Stroop task using happy and fearful facial expressions. The participants’ task was to detect the emotional expression (Happy or Fear) of the face shown with a distractor word (Happy or Fear) written across the face. Reaction time and accuracy data was analysed to compare adaptation effect and Stroop interference as a function of age, valence and previous trial congruence. The results demonstrated a stronger adaptation effect for negative affect in young adults and for positive affect in middle-aged adults and older adults. These results can be explained in terms of the socio-emotional selectivity theory of affective bias in the elderly and the involvement of attentional control mechanisms. This study empirically demonstrates shifts in affective bias towards positive affect with ageing through the implicit recruitment of cognitive control.

     

Dispositional optimism as a buffer against emotional reactivity to daily stressors: A daily diary approach

The current research examined if dispositional optimism buffers against the negative influences of daily stressors on affective experiences, using a daily diary study of two large and nationally-drawn samples of American adults (N = 2,349). Optimism, exposure to daily stressors, and daily positive and negative affect were assessed over eight days. Multilevel modelling revealed that optimism significantly attenuated the associations between daily stressor exposure and negative affect reactivity even after controlling for demographic factors, subjective physical health, and socioeconomic status. However, in a similar analysis, the inclusion of socioeconomic variables fully accounted for the moderating effect of optimism on stress and positive affect reactivity. The findings suggest distinct processes that are involved in how optimism reduces daily stress reactivity.     

Affective reactivity of language symptoms, startle responding, and inhibition in schizophrenia

The speech of some schizophrenia patients becomes markedly more disordered when negative affect is aroused. The authors tested associations between affective reactivity of speech and responsiveness and inhibition on an acoustic startle task in a sample of 27 outpatients. Patients whose language was reactive to negative affect showed significantly higher initial startle amplitudes than those whose language was not reactive. However, they also showed greater habituation to repeated startle stimuli over trials, even after differences in initial amplitudes were controlled statistically. These findings suggest that affective reactivity of speech is associated with higher initial startle responsiveness but also with greater habituation and, conversely, that patients who are relatively nonreactive to excitatory affective and sensory stimuli are also less reactive to inhibitory input.     

Age-related differences in profiles of mood-change trajectories

As a group, older adults report positive affective lives. The extent to which there are subgroups of older adults whose moods are less positive, however, is unclear. Our aim in the present study was to identify and characterize different subgroups of adults who exhibit distinct trajectories of mood change across a relatively short time period. Seventy-nine young and 103 older adults continuously reported their moods while viewing emotional and neutral faces. Cluster analysis revealed four subgroups of mood-change trajectories. Both the most positive and the most negative subgroups included more older than young adults (ps < .05), suggesting that not all older adults exhibit higher positive affect than young adults. Analyses of variance revealed that the most negative group exhibited slower processing speed, more state anxiety and neuroticism, and looked less at happy faces than the other groups (ps < .05). The results are discussed from an adult developmental perspective, focusing on the increased variability of mood trajectories in the older adults and whether this is a reflection of adaptive functioning or a potential harbinger of dysfunction.     

Affective responses to movie posters: differences between adolescents and young adults

Although the link between cognition and affect in the advertising context has been demonstrated in several studies, no research to date has considered adolescents’ affective responses to movie posters and their attitudes to negative and positive images. A 2 (between subjects) × 4 (within subjects) mixed‐factorial experiment design comprising two groups of subjects (80 adolescents and 80 young adults) and four advertising stimuli (two highly positive images and two highly negative images) was used to test the differences in the subjects’ attitudes to advertising, positive and negative affect, and viewing intentions. Although the adolescents, compared to the young adults, did not appear to have significantly stronger attitudes to emotional advertisements (ads), they showed a similar level of intensity of affective response when exposed to negative and positive images.     

Affect and Affect Regulation Strategies Reciprocally Influence Each Other in Daily Life: The Case of Positive Reappraisal,Problem-Focused Coping,Appreciation and Rumination

Feelings of positive or negative affect are not restricted to temporary states. They can also determine future affective experiences, by influencing the building of an individual’s personal resources. The present study was designed to understand the daily fluctuations in positive and negative affect more fully. To this end, we examined the involvement of a variety of affect regulation strategies in these fluctuations. The affect regulation strategies we explored included positive reappraisal, problem-focused coping, appreciation and rumination. We adopted an experience sampling method, consisting of five daily assessments over a 2-week period. As expected, within a few hours of experiencing more positive affect, participants engaged in greater positive reappraisal, problem-focused coping and appreciation. In turn, greater use of each of these three strategies was followed by more intense experiences of positive affect. We observed analogous reciprocal influences between rumination and the experience of negative affect, within the same time interval. Changes in affective experience over several hours were also directly influenced by concurrent use of these strategies. More specifically, greater positive reappraisal, problem-focused coping and appreciation accelerated the rise in positive affect that follows low feelings of positive affect, and slowed the decline in positive affect that follows high feelings. Rumination had an analogous influence on change in negative affect. The clinical implications of these findings are discussed.     

Who’s bringing the donuts: The role of affective patterns in group decision making

Two studies examined how intragroup affective patterns influence groups’ pervasive tendency to ignore the unique expertise of their members. Using a hidden profile task, Study 1 provided evidence that groups with at least one member experiencing positive affect shared more unique information than groups composed entirely of members experiencing neutral affect. This occurred because group members experiencing positive affect were more likely to initiate unique information sharing, as well as information seeking. Study 2 built upon this base by showing that confidence mediates the relationship between positive affect and the initiation of unique information sharing. Additionally, Study 2 investigated the role of negative affect in group decision making and how negative and positive affect concurrently influence decision making when groups are composed of members experiencing each. The results are discussed in terms of the role affect plays in influencing group behavior and the resultant importance of investigating specific affective patterns.     

Flow and Happiness in Later Life: An Investigation into the Role of Daily and Weekly Flow Experiences

Fifty-four older adults ranging in age from 70 to 86 years old (M = 77.54) reported daily levels of positive and negative affect, life satisfaction and daily activities for seven consecutive days. Hierarchical linear modeling (HLM) was used to investigate inter- and intra-individual effects of flow experiences on affect. Higher quality of flow was positively associated with high arousal positive affect (i.e., feeling peppy, enthusiastic, happy), negatively associated with low arousal negative affect (i.e., feeling sad and disappointed), and positively associated with life satisfaction. However, more frequent flow experiences throughout the week predicted lower average levels of positive affect and life satisfaction. Overall, the results demonstrate that flow is linked to the affective experiences of older adults, and that an individual’s overall propensity to experience flow may be influential beyond the immediate effects of a given flow experience.
