Valence focus and arousal focus: Individual differences in the structure of affective experience.

The structure of affect is well represented as a circumplex. The results of a within-subject longitudinal study of self-reported mood indicate individual differences in the circumplex structure of affective experience. These differences can be captured by two constructs: valence focus and arousal focus. Valence focus is the degree to which individuals attend the hedonic component of their affective experience; arousal focus is the degree to which individuals attend the arousal component of their affective experience. In this study, differences in individuals' attention to the hedonic and arousal components of affective experience were related to observed correlations between specific affective elements, such as (a) ratings of anxious and depressed mood and (b) "Negative Affect" and "Positive Affect."

Narcissism, affect, and gender: An empirical examination of Kernberg's and Kohut's theories of narcissism.

The activation of narcissistically affirming and disaffirming early memories were used to assess Kernberg's and Kohut's propositions regarding the roles of hostile, depressive, and positive affect in narcissistic character structures. After completing the Narcissistic Personality Inventory participants wrote either an early memory of pride, an early memory of shame, an unspecified memory, or no memory before completing the Projective Affect Scale and Multiple Affect Adjective Checklist. ANOVAs were conducted on participants ratings of hostile, depressive, and positive affect. The results indicated that for high relative to low narcissists, prideful and nonspecific memories resulted in less hostility, less pride, and more positive affect. Shameful memories resulted in higher projected hostility for high narcissists. Shame was negatively related to narcissism for males and positively related for females.

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

Investigated, in 2 experiments, 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 and self-reports that were related to negative affect. Moreover, Ss who smoked after exposure to withdrawal and stress reported greater pleasure and arousal than did other Ss. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Sad and guilty? Affective influences on the explanation of conflict in close relationships.

What is the role of mood in the way people explain interpersonal conflicts in their close relationships? On the basis of the multiprocess Affect Infusion Model (AIM) of judgments (J. P. Forgas, 1992, in press), 3 experiments, with a total of 306 Ss, found a nonobvious pattern of greater mood effects on attributions for serious rather than simple conflicts. In Exp 1, sad Ss blamed themselves more for conflicts than did happy Ss. Exp 2 found that in a field setting, sad persons attributed real-life conflicts more to internal, stable, and global causes and did so more for serious than for simple conflicts. Exp 3 replicated these findings in the laboratory and also produced reaction time (RT) data showing that it was the longer processing recruited by more serious conflicts that accentuated these affect-priming effects, as predicted by the AIM. The cognitive mechanisms linking affect and judgments are discussed, and the role of moods in everyday explanations of conflict is considered.

The "teacher's pet" phenomenon, students' perceptions of teachers' differential behavior, and students' morale.

The relationships among the teacher's pet phenomenon, students' perceptions of teachers' differential behavior, and students' morale were investigated in 80 upper elementary Israeli classrooms. The intensity of the teacher's pet phenomenon (rate of students' consensus in identifying teachers' pets in each classroom) was related to perceived teachers' differential behavior, particularly to teachers' differential (also preferential) affect. In turn, teachers' perceived differential affect was negatively related to students' morale and satisfaction. In classrooms of teachers who had pets who were not popular, students demonstrated lower morale, whereas students in "popular-pet" classrooms did not demonstrate lower morale. Previous findings on the teacher's pet phenomenon and on students' and teachers' perceptions of teachers' differential behavior were replicated.

"Affect dynamics, affective forecasting, and aging": Correction to Nielsen, Knutson, and Carstensen (2008).

Reports an error in "Affect dynamics, affective forecasting, and aging" by Lisbeth Nielsen, Brian Knutson and Laura L. Carstensen (Emotion, 2008[Jun], Vol 8[3], 318-330). The first author of the article was listed as being affiliated with both the National Institute on Aging and the Department of Psychology, Stanford University. Dr. Nielsen would like to clarify that the research for this article was conducted while she was a postdoctoral fellow at Stanford University. The copyright notice should also have been listed as "In the Public Domain." (The following abstract of the original article appeared in record 2008-06717-002.) Affective forecasting, experienced affect, and recalled affect were compared in younger and older adults during a task in which participants worked to win and avoid losing small monetary sums. Dynamic changes in affect were measured along valence and arousal dimensions, with probes during both anticipatory and consummatory task phases. Older and younger adults displayed distinct patterns of affect dynamics. Younger adults reported increased negative arousal during loss anticipation and positive arousal during gain anticipation. In contrast, older adults reported increased positive arousal during gain anticipation but showed no increase in negative arousal on trials involving loss anticipation. Additionally, younger adults reported large increases in valence after avoiding an anticipated loss, but older adults did not. Younger, but not older, adults exhibited forecasting errors on the arousal dimension, underestimating increases in arousal during anticipation of gains and losses and overestimating increases in arousal in response to gain outcomes. Overall, the findings are consistent with a growing literature suggesting that older people experience less negative emotion than their younger counterparts and further suggest that they may better predict dynamic changes in affect.

Affect and adult self-regulation.

100 female undergraduates reviewed 1 of 5 sets of 45 self-statements representing manipulations of affect (positive somatic, positive self-evaluation, negative somatic, negative self-evaluation, or neutral) and then completed an ostensibly separate task involving self-regulation of difficult or easy mathematics problems to examine the influence of induced affect on Ss' self-regulated performance and related subjective responses. Before and after the affect induction, Ss completed several measures of affect and self-perception, including the Multiple Affect Adjective Checklist and the Subjective Probability Questionnaire. Following the performance phase, Ss observed their problem-solving activities, evaluated them, and made attributional and other responses. It was hypothesized that (1) somatic affect inductions would prove most potent, (2) affect would have greater impact in the low-task-mastery context, and (3) positive vs negative affect inductions would produce differential effects, dependent on task-mastery condition. The somatic inductions more substantially influenced subjective reports and performance, in accord with Hypothesis 1, and the positive somatic induction significantly improved self-regulation only in the low-mastery condition, in partial support of Hypotheses 2 and 3. Discussion focuses on the importance of the arousal dimensions of affect and concomitant shifts in attentional foci as determinants of adult self-regulation.

Additivity of nonconscious affect: Combined effects of priming and exposure.

Affect deriving from 2 independent sources—repeated exposure and affective priming—was induced, and the combined effects were examined. In each of 4 studies, participants were first shown 72 Chinese ideographs in which the frequency of exposure was varied (0, 1, or 3). In the 2nd phase participants rated ideographs that were primed either positively, negatively, or not at all. The 4 studies were identical except that the exposure duration—suboptimal (4 msec) or optimal (1 sec)—of both the initial exposure phase and the subsequent priming phase was orthogonally varied. Additivity of affect was obtained only when affective priming was suboptimal, suggesting that nonconscious affect is diffuse. Affect whose source was apparent was more constrained. Interestingly, increases in liking generated through repeated exposures did not differ as a function of exposure duration. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

A longitudinal model of social contact, social support, depression, and alcohol use.

The longitudinal relations among contact with one's social network (social contact), perceived social support, depression, and alcohol use were examined. An integrative model was developed from affect regulation theory and theories of social support and dysfunctional drinking. Data were obtained from a random sample of 1, 192 adults. The 3-wave panel model was tested using structural equation modeling analysis. Results revealed that (a) social contact was positively related to perceived social support; (b) perceived social support was, in turn, negatively related to depression; and (c) depression was, in turn, positively related to alcohol use for 1 of 2 longitudinal lags. There was partial support for the feedback hypothesis that increased alcohol use leads to decreased contact with family and friends. Although the results generally supported the authors' hypotheses, the significant coefficients in the model were generally small in size.

Temporal and intensity coding of pain in human cortex

Temporal and intensity coding of pain in human cortex. J. Neurophysiol. 80:3312-3320, 1998. We used a high-resolution functional magnetic resonance imaging (fMRI) technique in healthy right-handed volunteers to demonstrate cortical areas displaying changes of activity significantly related to the time profile of the perceived intensity of experimental somatic pain over the course of several minutes. Twenty-four subjects (ascorbic acid group) received a subcutaneous injection of a dilute ascorbic acid solution into the dorsum of one foot, inducing prolonged burning pain (peak pain intensity on a 0-100 scale: 48 +/- 3, mean +/- SE; duration: 11.9 +/- 0.8 min). fMRI data sets were continuously acquired for approximately 20 min, beginning 5 min before and lasting 15 min after the onset of stimulation, from two sagittal planes on the medial hemispheric wall contralateral to the stimulated site, including the cingulate cortex and the putative foot representation area of the primary somatosensory cortex (SI). Neural clusters whose fMRI signal time courses were positively or negatively correlated (P < 0.0005) with the individual pain intensity curve were identified by cross-correlation statistics in all 24 volunteers. The spatial extent of the identified clusters was linearly related (P < 0.0001) to peak pain intensity. Regional analyses showed that positively correlated clusters were present in the majority of subjects in SI, cingulate, motor, and premotor cortex. Negative correlations were found predominantly in medial parietal, perigenual cingulate, and medial prefrontal regions. To test whether these neural changes were due to aspecific arousal or emotional reactions, related either to anticipation or presence of pain, fMRI experiments were performed with the same protocol in two additional groups of volunteers, subjected either to subcutaneous saline injection (saline: n = 16), inducing mild short-lasting pain (peak pain intensity 23 +/- 4; duration 2.8 +/- 0.6 min) or to nonnoxious mechanical stimulation of the skin (controls: n = 16) at the same body site. Subjects did not know in advance which stimulus would occur. The spatial extent of neural clusters whose signal time courses were positively or negatively correlated with the mean pain intensity curve of subjects injected with ascorbic acid was significantly larger (P < 0.001) in the ascorbic acid group than both saline and controls, suggesting that the observed responses were specifically related to pain intensity and duration. These findings reveal distributed cortical systems, including parietal areas as well as cingulate and frontal regions, involved in dynamic encoding of pain intensity over time, a process of great biological and clinical relevance.     

Psychometric properties of the Affect Intensity and Reactivity Measure adapted for Youth (AIR–Y).

A valid and reliable instrument for measuring affect intensity does not exist for adolescents; such a measure may help to refine understanding of emotion among youths. The purpose of the current study was to evaluate the psychometric properties and clinical relevance of a measure of affect intensity adapted for youths. Two hundred five community adolescents and 179 adolescents from a residential treatment program were recruited; both samples completed self-report questionnaires, and the community-based sample participated in positive and negative mood-eliciting laboratory tasks. Confirmatory factor analyses comparing multiple models indicated a 3-factor structure was the best fit. This Affect Intensity and Reactivity Scale for Youth (AIR–Y) evidenced good internal consistency and test–retest reliability, and the 3 factors showed incremental predictive validity for mood ratings following emotion-elicitation procedures, even after accounting for the relevant scale on the Positive and Negative Affect Scale for Children. Evidence for the clinical relevance of the AIR–Y, particularly the Negative Intensity factor, was found. Overall, the AIR–Y appears to be a psychometrically sound measure for the assessment of affect intensity among youths. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Development and Preliminary Validation of the Physiological Hyperarousal Scale for Children.

Considerable empirical support exists for the positive affect and negative affect components of the tripartite model of anxiety and depression proposed by L. A. Clark and D. Watson (1991); however, less attention has been paid to the physiological hyperarousal component of the model. The development of the Physiological Hyperarousal Scale for Children (PH-C; J. Laurent, S. J. Catanzaro, & T. E. Joiner Jr., 1995) is described. The psychometric properties of items are examined using students in Grades 6-12 (N = 398). Initial scale validation includes a joint factor analysis with the Positive and Negative Affect Scale for Children (PANAS-C; J. Laurent et al., 1999; J. Laurent, K. Potter, & S. J. Catanzaro, 1994). The relationship between the PH-C and existing measures that tap related constructs is examined. Together, the PH-C and PANAS-C provide a means to assess tripartite model constructs useful in differentiating anxiety and depression.

Immediate antecedents of cigarette smoking: An analysis from ecological momentary assessment.

The authors assessed the association between smoking and situational cues, including affect, in realworld contexts. Using ecological momentary assessment, 304 smokers monitored ad-lib smoking for 1 week, recording each cigarette on palm-top computers. Generalized estimating equations contrasted 10,084 smoking and 11,155 nonsmoking situations. After controlling for smoking restrictions, smoking was strongly related to smoking urges and modestly related to consumption of coffee and food, the presence of other smokers, and several activities. Smoking was unrelated to negative or positive affect or to arousal, although it was associated with restlessness. Thus, in daily life, affect appears to exert little influence over ad-lib smoking in heavy smoking adults. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Why do some students avoid asking for help? An examination of the interplay among students' academic efficacy, teachers' social–emotional role, and the classroom goal structure.

With hierarchical linear modeling, student reports of the avoidance of help seeking were related to student and classroom characteristics. Avoidance of help seeking was related negatively to students' academic efficacy. However, avoidance of help seeking was related less strongly to students' academic efficacy in classrooms in which teachers believed they should attend to their students' social and emotional needs. Average levels of avoidance of help seeking were related to students' perceptions of the classroom goal structure: A perceived emphasis on self-improvement was related to lower levels of help avoidance, whereas a perceived emphasis on relative ability was associated with higher levels. Teacher reports of their approaches to instruction (emphasizing self-improvement or emphasizing relative ability) were unrelated to students' avoidance of help seeking.

M3 muscarinic receptor-mediated enhancement of NMDA-evoked adenosine release in rat cortical slices in vitro

Acetylcholine plays an important role in cortical arousal. Adenosine is released during increased metabolism and has been suggested to be a sleep-promoting factor. To understand the interaction of acetylcholine and adenosine in regulating cortical excitability, we examined the effect of carbachol on NMDA-evoked adenosine release and identified the muscarinic receptor subtype that mediated this effect in adult rat cortical slices in vitro. Carbachol (to 300 microM) alone did not affect the basal release of adenosine. However, carbachol (100 microM) induced a 253% increase in NMDA (20 microM)-evoked adenosine release in the presence of Mg2+. In the absence of Mg2+, carbachol's potentiating effect was less (60% increase). The nonselective muscarinic antagonist atropine (1.5 microM) blocked the facilitatory effect of carbachol on NMDA-evoked adenosine release, and this was mimicked by the M3-selective antagonist 4-diphenylacetoxy-N-methylpiperidine (1 microM). Neither an M1-selective dose of pirenzepine (50 nM) nor the M2-selective antagonist methoctramine (1 microM) affected carbachol's action on NMDA-evoked adenosine release. Carbachol had no effect on adenosine release evoked by alpha-amino-3-hydroxy-5-methylisoxazole-4-propionate (AMPA). These results suggest that acetylcholine does not affect basal adenosine release but enhances NMDA receptor-mediated evoked adenosine release by acting at M3 receptors in the cortex. This interaction may have a role in regulating cortical neuronal excitability on a long-term basis.
