The measurement of core affect: a Swedish self-report measure derived from the affect circumplex

Three studies were conducted with the aim of developing a new Swedish self-report measure of core affect (the Swedish Core Affect Scale or SCAS). In Study 1,122 participants rated their current mood on 24 unipolar adjective scales. A revised set of 12 bipolar adjective scales was evaluated in Study 2 employing 96 participants who rated their current mood before and after a mood-inducing naturally occurring event. A slightly revised set of adjective scales was used in Study 3, in which another 96 participants rated several induced moods. The results showed that the adjective scale ratings could be aggregated as reliable measures of the independent valence and activation dimensions proposed in the affect circumplex, and that the aggregated measures discriminated mood differences within and between individuals.     

The independence of positive and negative affect depends on the affect measure

This study examined the degree of independence between Positive Affect (PA) and Negative Affect (NA) within a given situation. The affective state was measured before and after an experimentally induced success or failure experience in an anagram task. Two types of affect measures were used to assess PA and NA: the Positive and Negative Affect Schedule (PANAS) and a Pleasantness-Unpleasantness scale. Consistent with our hypotheses, results show that PA and NA are independent when measured with the PANAS but are correlated when assessed with the other scale. These PA-NA correlations differed significantly from each other before and after emotion induction, respectively. Additional analyses indicate that both PA scales are differentially sensitive to the mood induction procedure. The findings are discussed with respect to circumplex models of emotion.     

Core affect and the psychological construction of emotion

At the heart of emotion, mood, and any other emotionally charged event are states experienced as simply feeling good or bad, energized or enervated. These states--called core affect--influence reflexes, perception, cognition, and behavior and are influenced by many causes internal and external, but people have no direct access to these causal connections. Core affect can therefore be experienced as free-floating (mood) or can be attributed to some cause (and thereby begin an emotional episode). These basic processes spawn a broad framework that includes perception of the core-affect-altering properties of stimuli, motives, empathy, emotional meta-experience, and affect versus emotion regulation; it accounts for prototypical emotional episodes, such as fear and anger, as core affect attributed to something plus various nonemotional processes.     

Studying Affect Among the Chinese: The Circular Way

Past research on Chinese emotion has been plagued by the lack of a measurement map for affective feelings. In this article, I developed a fine-grained circumplex model of affective feelings that is arbitrarily defined by 12 segments. I created twelve 4-item self-report scales to measure affect felt during a clearly remembered moment (N = 395), and I cross-validated them twice with affect felt during the current moment (Ns = 269, 302). The structural and psychometric properties of these scales were strongly supported. The CIRCUM-extension procedure (M. Browne, personal communication, June 12, 1999) that places external correlates into the affective space showed that 28 of 28 mood states and 6 of 13 traits were significantly related to affect. External correlates did not clarify which of the affect dimensions were basic. The newly developed scales will serve as a useful tool in assessing affect among Chinese people and as a platform on which to extend the nomological net of affect.     

Development and validation of brief measures of positive and negative affect: the PANAS scales

In recent studies of the structure of affect, positive and negative affect have consistently emerged as two dominant and relatively independent dimensions. A number of mood scales have been created to measure these factors; however, many existing measures are inadequate, showing low reliability or poor convergent or discriminant validity. To fill the need for reliable and valid Positive Affect and Negative Affect scales that are also brief and easy to administer, we developed two 10-item mood scales that comprise the Positive and Negative Affect Schedule (PANAS). The scales are shown to be highly internally consistent, largely uncorrelated, and stable at appropriate levels over a 2-month time period. Normative data and factorial and external evidence of convergent and discriminant validity for the scales are also presented.     

Measurement and mismeasurement of mood: recurrent and emergent issues

The affective explosion in psychology has led to tremendous advances in mood measurement. Mood ratings reflect a hierarchical structure consisting of two broad dimensions-Positive Affect and Negative Affect-and multiple specific states. Brief scales have been developed that reliably assess Positive and Negative Affect across different populations and time frames, in both between- and within-subject data. We examine controversies related to (a) the content of these higher order scales and (b) the independence of Positive and Negative Affect. Regarding the latter, we show that Positive and Negative Affect scales remain largely independent across a wide range of conditions, even after controlling for random and systematic error. Finally, there remains little consensus regarding the lower order structure of affect. This lack of a compelling taxonomy has substantially slowed progress in assessing mood at the specific affect level.     

Sinuosity and the Affect Grid: a method for adjusting repeated mood scores

Sinuosity is a measure of how much a travelled pathway deviates from a straight line. In this paper, sinuosity is applied to the measurement of mood. The Affect Grid is a mood scale that requires participants to place a mark on a 9 x 9 grid to indicate their current mood. The grid has two dimensions: pleasure-displeasure (horizontal) and arousal-sleepiness (vertical). In studies where repeated measurements are required, some participants may exaggerate their mood shifts due to faulty interpretation of the scale or a feeling of social obligation to the experimenter. A new equation is proposed, based on the sinuosity measure in hydrology, a measure of the meandering of rivers. The equation takes into account an individual's presumed tendency to exaggerate and meander to correct the score and reduce outliers. The usefulness of the equation is demonstrated by applying it to Affect Grid data from another study.     

Emotion,core affect,and psychological construction

As an alternative to using the concepts of emotion, fear, anger, and the like as scientific tools, this article advocates an approach based on the concepts of core affect and psychological construction, expanding the domain of inquiry beyond “emotion”. Core affect is a neurophysiological state that underlies simply feeling good or bad, drowsy or energised. Psychological construction is not one process but an umbrella term for the various processes that produce: (a) a particular emotional episode's “components” (such as facial movement, vocal tone, peripheral nervous system change, appraisal, attribution, behaviour, subjective experience, and emotion regulation); (b) associations among the components; and (c) the categorisation of the pattern of components as a specific emotion.     

Validation of a Swedish short self-report measure of core affect

This research aimed at validating two self-report composite rating scales of core affect that are useful when quick assessments are required, for instance, of current mood or recalled, anticipated, and experienced emotional reactions. The ratings were derived from the Swedish Core Affect Scales (SCAS) comprising six self-report rating scales of the two orthogonal dimensions of core affect, valence (unpleasantness-pleasantness) and activation (quietness-excitement). In three samples of university students who were requested to rate current moods, affect-inducing sounds, or affect-inducing pictures, the composite ratings were compared to SCAS, two widely used graphical rating scales of valence and activation, and skin conductance responses and the acceleratory peak of heart rate. Three different rating formats were also compared. The results showed that the composite ratings were reliable and yielded the expected correlations with the other ratings and with the physiological affect indicators. No effects of rating format were detected. It is concluded that the composite ratings of valence and activation may be used if quick assessments are called for. Choices can be made of any of three rating formats depending on purpose with the assessments.     

Changes in mood caused by staged, moderate physical activity]

This experiment provides a test for the common sense knowledge that moderate physical exercise leads to mood improvement. Furthermore, it was tested whether light exercise intensifies negative feeling states or alleviates them. 30 female and 30 male students of psychology served as subjects (mean age 25.3 years, SD = 4.8). After being exposed to a mood induction procedure designed to elicit either a positive or negative feeling state, the subjects had to pedal a bicycle ergometer with 0, 50 or 75 Watt load. Cardiovascular variables and self-reports of mood states were assessed during a baseline period, after the mood induction, following the ergometer exercise, and after a follow-up period. The mood induction procedures were successful, but only for a short duration. Physiological activation was observed according to the ergometer loadings. Moderate physical exercise led to an increase of positive feeling states (Concentration) and a decrease of negative feeling states (Tiredness) in the follow-up period. Corresponding changes in tension related states could not be observed, probably due to the weakness of the mood induction procedure employed and the low level of energetic activation reached.     

The neurodynamics of emotion: delineating typical and atypical emotional processes during adolescence

The study of development is, in and of itself, the study of change over time, but emotions, particularly emotional reactivity and emotional regulation, also unfold over time, albeit over briefer time‐scales. Adolescence is a period of development characterized by marked changes in emotional processes and rewiring of the underlying neural circuitry, making this time of life formative. Yet this period is also a time of increased risk for anxiety and mood disorders. Changes in the temporal dynamics of emotional processes (e.g. magnitude, time‐to‐peak and duration) occur during this developmental period and have been associated with risk for mood and anxiety disorders. In this article, we describe how the temporal dynamics of emotions change during adolescence and how they may increase risk for these psychopathologies. We highlight studies that illustrate how formalizing temporal neurodynamics of emotion may enhance links among levels of analyses from neurobiological to real‐world, moment‐to‐moment experiences.     

Assessing the dysregulation of the Behavioral Activation System: the Hypomanic Personality Scale and the BIS-BAS scales

We discuss the Hypomanic Personality Scale (Hyp; Eckblad & Chapman, 1986) and the Behavioral Inhibition System (BIS-BAS; Carver & White, 1994) and Behavioral Activation System (BAS; Gray, 1991) Scales as risk factors for bipolar disorders. The dysregulation of the BAS is considered to be central and results in higher variability in mood. Therefore, we examined how those scales are associated with mood fluctuations. A total of 59 participants completed a diary for at least 17 days. It included a modified Center for Epidemiologic Studies-Depression Scale (Meyer & Hautzinger, 2001) assessing depression and mania and the Positive and Negative Affect Schedule (Watson, Clark, & Tellegen, 1988). Hyp and BAS predicted levels of mania and of positive affect but also fluctuations of mania. Hyp also predicted instability of negative affect. Our data also suggest that mood variability is a trait-like feature. Both scales seem not to be perfect measures of the dysregulation factor. Future research should assess this dysregulation more directly.     

Mood specific media use and emotion regulation: Patterns and individual differences

The present study examines moods in which individuals are most likely to utilize various forms of entertainment media and the emotion regulation tendencies that are associated with such preferences. Results of a questionnaire study (n = 229) show that mood specific media use may be captured by three factors: turning to media in a positive mood, in a negative mood or in a bored mood. Findings also show that various forms of difficulty regulating emotion (e.g., feeling out of control when upset) predict media use in negative or bored moods only. More specific analyses show that music use in negative moods is predicted by both positive indices (e.g., reflection tendencies) and negative indices of emotion regulation (e.g., rumination tendencies), while television use in negative moods is only predicted by negative indices of emotion regulation. Results are discussed in light of the psychological needs that selective media use may serve.     

Standing up for an affective account of emotion

This paper constitutes a defence of an affective account of emotion. I begin by outlining the case for thinking that emotions are just feelings. I also suggest that emotional feelings are not reducible to other kinds of feelings, but rather form a distinct class of feeling state. I then consider a number of common objections that have been raised against affective accounts of emotion, including: (1) the objection that emotion cannot always consist only of feeling because some emotions—for example, indignation and regret—necessarily have a cognitive component (say, the perception of a lost opportunity in the case of regret); (2) the objection that emotion cannot consist only of feeling because in order to explain how emotions have intentional objects we will have to recognise that emotion consists of cognition; and (3) the objection that emotion cannot consist only of feeling because emotion, but not feeling, can be variously assessed or evaluated. However, I demonstrate how an affective account of emotion might be successfully defended against all of the objections that are cited.     

父母述情困难与儿童行为问题:父母心境的中介作用

采用整群抽样法选取438名学前儿童及其家长为被试, 通过量表考察父母述情困难、心境与儿童问题行为之间的关系。结果发现:(1)父亲述情困难与儿童焦虑害羞行为显著正相关, 父亲情绪愉悦在其述情困难与儿童焦虑害羞行为之间具有完全中介作用;(2)母亲述情困难与儿童愤怒攻击、焦虑害羞行为显著正相关, 同时母亲的情绪波动在其述情困难与儿童愤怒攻击行为之间起着部分中介作用。研究结果说明述情困难风险较高的父亲, 其情绪愉悦水平也相对较低, 进而导致儿童表现出更多焦虑害羞行为;述情困难风险较高的母亲, 一方面会直接导致儿童表现出较多愤怒攻击与焦虑害羞行为, 另一方面又会通过其情绪波动增加儿童出现愤怒攻击行为的风险。     

Seven sins in the study of emotion: correctives from affective neuroscience

This brief commentary highlights seven sins in the study of emotion that are explicitly treated in contemporary affective neuroscience. These sins are (1) Affect and cognition are subserved by separate and independent neural circuits; (2) Affect is subcortical; (3) Emotions are in the head; (4) Emotions can be studied from a purely psychological perspective; (5) Emotions are similar in structure across age and species; (6) Specific emotions are instantiated in discrete locations in the brain; and (7) Emotions are conscious feeling states. Each of these is briefly discussed and evidence from affective neuroscience that bears on these sins is noted. The articles in this Special Issue underscore the vitality of research in affective neuroscience and illustrate how some of these sins can be addressed and rectified using concepts and methods from affective neuroscience.     

The relationship between daily events and mood: The mood measure may matter

Measures of daily mood have been used as immediate indicators of the effects of the psychosocial environment, the latter concept often measured by daily events. We examined the prediction of two measures of daily mood, the Positive and Negative Affect Schedule (PANAS) and Nowlis Mood Adjective Checklist (MACL), by daily desirable and undesirable events and by day of the week. Unlike prior studies, the event assessment and type of subjects studied (community residents) were the same in both studies, allowing an attribution of differential associations between the two mood scales and either daily events or day of the week to the different mood measures. The mood measures had similar and expected associations with daily events, although the MACL scale generally had stronger associations with events. Surprisingly, the pattern of day of the week effects for positive, yet not negative, mood were different for the two mood measures. Consistent with the weekend's increase in desirable daily events, MACL positive affectincreased on weekends, relative to weekdays, whereas PANAS positive mooddecreased on weekends. Also, for both positive and negative affect scales, the MACL scales had stronger associations with day of week than the PANAS scales. These results suggest caution in the choice of mood measure to use in studies of daily events and pose questions about the meaning of these mood measures.This work was supported, in part, by grant MH39234 from NIMH.

Emotional Experience and Its Relation to the Five-Factor Model in Estonian

ABSTRACT In this article we studied relations between self-rated emotional experience and the five-factor model of personality. Replicating previous findings we found that two dominant dimensions of emotional experience, Negative Affect and Positive Affect (that accounted for three to five times more total variance among Estonian emotion-related terms than any other factors) are selectively related to Neuroticism and Extraversion. Data supported the hierarchical taxonomy scheme proposed by Watson and Clark (1992) in which two broad higher order affective states were each composed of several correlated but still clearly distinguishable moods with their specific content. The content of specific emotions mapped systematically onto measures of personality: Affect scales explained 40% to 50% of the total variance of Neuroticism, Extraversion, and Conscientiousness, approximately 20% of the total variance of Agreeableness, and only 13% of Openness to Experience. Besides the replication of the hierarchical bipartite structure of emotion terms itself in a non-Indo-European language, our data demonstrated that the general pattern of associations between affect and personality domains is also generalizable across languages and cultures.     

情绪如何引发暴力犯的攻击?基于情绪调节理论的解释

本文基于情绪调节理论, 以暴力犯为被试, 通过2项研究探究了情绪在攻击产生过程中的作用。研究1采用改编的反应时竞争范式测量个体攻击行为。结果发现, 情绪调节动机在负性情绪与攻击间起完全中介作用, 证实了负面情绪状态下, 暴力犯会为了调节情绪而实施攻击。研究2进一步表明, 攻击的确能起到调节情绪的作用。具体来说, 在暴力犯群体中, 实施反应性攻击之后, 会伴随着正性情绪的提升和负性情绪的下降; 实施主动性攻击之后, 个体的正性情绪和负性情绪都会提升。文章从对攻击结果的预期和攻击的实际效果两个角度, 对攻击的情绪调节理论进行了验证, 为情绪在攻击产生过程中的作用提出了新的解释。今后的研究和实践过程中, 应设法避免个体通过攻击调节情绪, 引导其使用合理的方式调节情绪以减少攻击行为的产生。
