Individual Differences In Negative Affect Research Articles

Brain activity in ventromedial prefrontal cortex correlates with individual differences in negative affect.

Individuals differ in the extent to which they experience negative mood states over time. To explore the relationship between individual differences in negative affect (NA) and brain activity, we asked healthy subjects participating in positron-emission tomography scans to rate the extent to which they had experienced NA terms during the month before scanning. In two independent samples of subjects, resting regional cerebral blood flow within the ventromedial prefrontal cortex (VMPFC) correlated with ratings of NA. The finding converges with recent evidence implicating the VMPFC in emotional and autonomic processing. Moreover, it demonstrates that variability in basal VMPFC activity across subjects is related to individual differences in subjective emotional experience.

Facing guilt: Role of negative affectivity, need for reparation, and fear of punishment in leading to prosocial behaviour and aggression

The present study aims to further corroborate and to extend the scope of previous findings regarding the path of influence between negative affectivity, need for reparation and fear of punishment when examining the determinants and the motivational components of guilt. Data were collected from three different European countries (i.e. Italy, Hungary, and the Czech Republic). About 1100 young adolescents were involved in the research. The generalizability of a nomological network linking individual differences in Negative Affectivity to Need for Reparation, Fear of Punishment, Prosocial Behaviour, and Aggression has been investigated across countries and gender, by means of structural equation modelling. Need for Reparation turns out to be positively related to Prosocial Behaviour and negatively related to Aggression. Fear for Punishment turns out to be positively related to Aggression and negatively related to Prosocial Behaviour, with the exception of Hungary. Alternative paths of influence among considered variables have been examined. Practical implications for prevention and education are underlined. Copyright © 2001 John Wiley & Sons, Ltd.

Negative affectivity, perceived occupational stress, and health during organisational restructuring: A follow-up study

This paper presents a survey of the relationships among multiple indicators of perceived occupational stress, trait negative affectivity, and later mental and physical health symptoms, among 157 Australian public servants during organisational restructuring. It was hypothesised that individual differences in negative affectivity would inflate the relationships between perceived stress and later strain as assessed by health symptoms in the follow-up phase. The possible role of negative affectivity in moderating the stress-strain relationships was also investigated. Multiple regression analyses conducted with depressive and physical health outcomes separately indicate that the only significant predictors of depressive symptoms were negative affectivity and role insufficiency, whereas the significant predictors of physical health symptoms were role ambiguity, physical environment, and negative affectivity. None of the interaction terms involving occupational stress and negative affectivity was found to be significant Implications of the findings are discussed in the context of the research literature on work stress, particularly the role of negative affectivity in inflating the stress-strain relationship and indications for future research.

Respiratory learning and somatic complaints: A conditioning approach using CO 2-enriched air inhalation

In a differential respiratory conditioning paradigm with normal Ss two odors (fresh smelling niaouli and bad smelling ammonia) were used as conditioned stimuli (CS+ or CS−) and 7.4% CO 2-enriched air was used as the unconditioned stimulus (US). Three CS+ and three CS− trials were run during acquisition, followed on the next day by the same number of CS+ and CS− only trials. Respiratory frequency, minute ventilation, end-tidal fractional concentration of CO 2 and subjective complaints were measured throughout the experiment. While during acquisition all measures were affected, the conditioning effects included only respiratory frequency and subjective complaints. A selective association effect appeared in that the conditioning effects were confined to ammonia as CS+: respiratory frequency increased and more somatic complaints were presented when compared to the CS− condition. The conditioning effect on complaints was not confined to complaints of general arousal, but included respiratory complaints as well. Correlational analyses showed that increases in complaints as caused by the conditioning procedure were predicted by changes in somatic variables, but not by individual differences in Negative Affectivity.

Negative affect and hindsight bias

AbstractThe relationship between hindsight bias and individual differences in negative affect, or ‘dysphoria’, was investigated in a naturalistic study. In a first session, 76 undergraduates predicted their grades prior to a midterm exam. In a second session, after having received feedback from the exam, they attempted to recall their predictions and predicted their grades on a second exam. Dysphoria was associated with hindsight bias whether initial predictions were overly optimistic or pessimistic. In the former case, the standard hindsight bias was modal for the sample, whereas a ‘reverse hindsight’ bias was modal in the latter. This asymmetry suggests that hindsight bias is influenced by motivational or affective factors. The bias did not hinder the improvement of predictions between the first and second exams, and therefore could not have mediated a hypothesized adaptive learning impairment among dysphoric subjects.

Intraindividual and interindividual analyses of positive and negative affect: Their relation to health complaints, perceived stress, and daily activities.

I examined correlates of Negative Affect (NA) and Positive Affect (PA) through both within- and between-subjects analyses. Eighty subjects completed a daily questionnaire for 6-8 weeks. Each day they rated (a) their mood, (b) the extent to which they suffered from various minor physical problems, (c) their level of stress, (d) the time they spent socializing, and (e) whether or not they had exercised. Subjects also completed several trait tests measuring their general affective level, frequency of health problems, and social tendencies. A between-subjects analysis showed the expected pattern: Level of physical complaints and perceived stress were correlated with individual differences in NA but not in PA, whereas social indicators and frequency of exercise were related only to PA. The within-subjects results generally exhibited a similar pattern: Social activity and exercise were more strongly related to PA, whereas perceived stress was highly related to NA. However, the most significant finding was that, contrary to prediction, health complaints were as strongly related to intraindividual fluctuations in PA as in NA. Possible interpretations of the observed correlates of NA and PA are discussed.
