Introversion,inhibition, and displayed anxiety: The role of error reactivity processes

Three studies involving 176 undergraduates examined the personality-related correlates of tendencies to slow down following errors in choice reaction time tasks. Such tendencies were hypothesized to tap individual differences in threat reactivity processes and therefore be relevant to the prediction of phobic-like fear (Study 1) and displayed anxiety as rated by informants (Studies 2 and 3). However, on the basis of the idea that high levels of extraversion may suppress threat reactivity processes, it was hypothesized that extraversion and post-error slowing tendencies would interact in predicting the dependent measures. The studies supported the latter interactive hypothesis in that post-error slowing tendencies were predictive of displayed anxiety at low, but not high, levels of extraversion. The discussion focuses on the respective roles of error-reactivity processes and extraversion in predicting behavioral inhibition and displayed anxiety.     

Traits, States, and encoding speed: support for a top-down view of neuroticism/state relations

Recent theories suggest that trait neuroticism gains its pernicious power particularly among individuals less capable of making distinctions concerning present reality. Four studies, involving 272 undergraduates, sought to provide some basic, assessment-related support for such theories in the context of individual differences in choice reaction time, which reflect abilities to make distinctions at encoding. Studies 1-3 focused on somatic symptoms, whereas Study 4 focused on neurotic behaviors and negative affect. As predicted, neuroticism consistently interacted with categorization speed in predicting these dependent measures. Specifically, neuroticism/outcome relations were robust among individuals slow to make distinctions at encoding; by contrast, neuroticism did not predict the dependent measures among individuals fast to make distinctions. Such data reinforce suggestions that neuroticism is particularly pernicious among individuals less capable of making distinctions at encoding.     

Does “feeling down” mean seeing down? Depressive symptoms and vertical selective attention

Prior research reveals that the encoding of affective stimuli is biased in a metaphorically consistent manner (e.g., good = up; bad = down). For example, negative words are evaluated faster if they are presented in a low versus high vertical position. The present studies extended this view by investigating whether such biases also correlate with individual differences in emotional experience. Specifically, in two studies, we examined whether vertical metaphor would be useful in understanding negative affect as manifested in neuroticism and depressive symptoms. We found support for this premise. That is, the higher the neuroticism (Studies 1 and 2) or depressive symptoms (Study 2) of participants, the faster they were to respond to or detect lower (versus higher) spatial attention targets. These results suggest that negative affect in general, and depressive symptoms in particular, appear to bias selective attention in a direction that favors lower regions of physical space.     

Moody and thin-skinned? The interplay of neuroticism and momentary affect in older romantic couples

Neuroticism is associated with heightened reactivity to social stressors. However, little is known about the micro-processes through which neuroticism shapes – and is shaped by – affective experiences in close relationships. We examine the extent to which momentary affect is coupled with one’s relationship partner, whether the strength of this coupling differs depending on levels of neuroticism, and whether this coupling and partner’s overall level of positive or negative affect prospectively contribute to differential (rank-order) changes in neuroticism. Older couples (N = 82, aged 67–93 years) rated their momentary affect six times per day for one week and provided ratings of trait neuroticism at baseline and 18 months later. Multilevel models revealed that among individuals high in neuroticism, individual positive affect was more closely coupled with partner positive affect compared with individuals low in neuroticism. Moreover, neuroticism decreased over time in those participants who showed a higher degree of coupling with partner positive affect and also had a partner with higher overall positive affect. In contrast, neuroticism increased in individuals whose partner had lower overall positive affect. Similar effects were not observed for negative affect. Our findings highlight how relationship partners contribute to daily affective experiences and longer-term changes in neuroticism.     

You May Worry,But Can You Recognize Threats When You See Them?; Neuroticism,Threat Identifications,and Negative Affect

The present studies sought to investigate the hedonic consequences of threat-identification skills at low and high levels of neuroticism. Such skills were assessed in terms of both speed (Study 1) and accuracy (Study 2) of identifying threatening objects in cognitive tasks. As predicted, threat-identification skills interacted with trait neuroticism in predicting subjective experiences. Specifically, individuals high in neuroticism experienced lower levels of negative affect during their everyday lives if they were also skilled in identifying threats in the cognitive tasks (Studies 1-2). Such skills did not matter at low levels of neuroticism. This interactive pattern was also replicated in the context of life domain satisfaction (Study 2). The results support the view that avoidance motivation encompasses multiple component processes, including some that are cognitive in nature, and specifically extends self-regulatory views of neuroticism. Of most importance, our data indicate that threat-identification skills can be hedonically beneficial, rather than costly, at high levels of neuroticism.     

Trait anger,neuroticism, and the hostile reaction to provocation: examining the hierarchical organization of affective traits in context

It has been suggested that the broad trait of neuroticism may predict the tendency to become aggressive when provoked. Based on functionalist theories of emotion, however, we suspected that only the more specific trait of anger would predict such tendencies. To test these competing predictions, two laboratory studies and one daily diary study were conducted. Consistent with functionalist accounts, trait anger consistently predicted the angry emotional and aggressive behavioral response to provocation, even after controlling for neuroticism. This was true in relation to laboratory-based provocations and in provocations experienced in daily life. Neuroticism only predicted a more diverse negative emotional reaction. It is therefore proposed that trait anger clearly elicits an angry emotional response, which directly motivates aggressive behavior. By contrast, neuroticism may lead to a very diverse reaction which elicits different and even contradictory behavioral tendencies.     

Intrusive thoughts mediate the association between neuroticism and cognitive function

Although research has established a negative association between trait neuroticism and cognition, little is known about the mechanisms that underlie this relationship. We examined the tendency to experience intrusive thoughts and negative affect as potential mediators of the relationship between neuroticism and cognitive performance. We hypothesized that the tendency to experience intrusive thoughts reflects ineffective attentional control and would account for the relationship between neuroticism and cognitive performance over and above the mediating effect of negative affect. Three hundred seventeen adults (M_age = 49.43) completed a series of attention-demanding cognitive tasks as well as self-report measures of intrusive thoughts, negative affect, and neuroticism. Intrusive thoughts mediated the association between trait neuroticism and cognitive performance beyond negative affect. These findings are consistent with the hypothesis that the tendency to experience intrusive thoughts is a mechanism through which trait neuroticism influences cognitive performance.     

Trait emotions and affective modulation of the startle eyeblink: on the unique relationship of trait anger

We examined relationships among individual differences in trait emotions and the emotion-modulated startle-eyeblink response. In particular, we examined the extent to which trait anger, which is negative in valence, would be associated with a pattern of approach motivation in startle eyeblink responses to appetitive stimuli. Self-reported trait emotions were compared with emotion-modulated startle eyeblink responses to auditory probes during appetitive, aversive, and neutral pictures. Results revealed that trait anger, enjoyment, and surprise were each associated with greater blink inhibition to appetitive pictures, indicating an approach motivational response. No other trait emotions were associated with startle eyeblink responses to appetitive or aversive pictures. These results support the idea that trait anger, although experienced as a negative emotion, is associated with an approach-related motivational response to appetitive stimuli at basic, reflexive levels of processing.     

Individual differences in the experience of depressive and anxious, intrusive thoughts

Cognitive—clinical theorists such as Beck have implicated various personality traits as vulnerability factors in the experience of negative, distressing cognitions. A cluster analysis, performed on the basis of Ss' responses to a questionnaire specially constructed to assess anxious and depressive thoughts for features such as frequency, sadness, worry, controllability and unacceptability, demonstrated individual differences in the experience of negative cognitions. These differences were associated with varying levels of trait anxiety, dysphoria and obsessionality. Further analysis revealed that trait anxiety and neuroticism were more strongly associated with depressive rather than anxious cognitions. Obsessional complaints evidenced minimal association with anxious thoughts, though a moderate correlation was obtained between the former and depressive self-statements. It is suggested that personality factors are influential in the experience of negative cognitions in a highly specific manner.     

Variability in affective change among aging men: Longitudinal findings from the VA Normative Aging Study

We examined change in both positive and negative affect over ages 45 to 97 among 1534 men (mean age = 69 years). Positive affect demonstrated a linear decline with age, while negative affect declined until approximately 70 years, and thereafter showed a gradual increase. Results indicated significant individual differences in rates of change for both positive and negative affect. We then examined whether personality, health, and work status might account for individual differences in levels and rates of change in affect. Higher extraversion was associated with higher levels of positive affect, but not with rate of change. Higher neuroticism predicted higher levels of negative affect, as well as an attenuated decline in middle-adulthood, and a steeper increase in later adulthood. Better health was associated with higher levels of positive affect and lower levels of negative, but was also found to predict less decline in negative affect. Work predicted lower levels of positive affect and higher levels of negative affect, as well as greater declines in positive affect. These findings indicate that individuals differ in the manner in which they change in affect over time.     

Alterations in error-related brain activity and post-error behavior over time

This study examines the relation between the error-related negativity (ERN) and post-error behavior over time in healthy young adults (N=61). Event-related brain potentials were collected during two sessions of an identical flanker task. Results indicated changes in ERN and post-error accuracy were related across task sessions, with more negative ERN associated with greater improvements in post-error accuracy. This relationship was independent of any cross-sectional relationships between overall task performance, individual difference factors, including personality and self-efficacy, and indices of self-regulatory action monitoring. These results indicate that the relation between ERN and post-error accuracy remains intact and consistent regardless of variation in this set of individual difference factors previously associated with both of these indices of self-regulatory action monitoring, providing support for the strength, robustness, and persistence of this relationship in the process of adaptively controlling behavior to enhance task performance.     

Cognitive sources of evidence for neuroticism's link to punishment-reactivity processes

Theories of neuroticism emphasise its close potential link to punishment-reactivity processes, yet cognitive sources of evidence for this proposed processing basis are surprisingly scarce. The present two studies (N = 123) sought to rectify this important gap in the literature in terms of reactivity to error feedback. Study 1 found that individuals high in neuroticism were faster to switch behavioural responses following errors, whereas an opposite pattern was found among individuals low in neuroticism. Study 2 extended this error-reactivity perspective to the realm of behavioural decision making. Individuals high in neuroticism switched their behavioural predictions following error feedback, whereas this tendency was non-significant among individuals low in neuroticism. Together, the studies present novel, but theory-informed, cognitive paradigms for assessing punishment-reactivity processes, confirm neuroticism's link to such processes, and do so in the realms of both reaction time (Study 1) and behavioural predictions (Study 2). The discussion focuses on the utility of modelling punishment-reactivity processes in cognitive terms and highlights relevant directions for future research.     

Thumbs up or thumbs down? Effects of neuroticism and depressive symptoms on psychophysiological responses to social evaluation in healthy students

The effects of neuroticism and depressive symptoms on psychophysiological responses in a social judgment task were examined in a sample of 101 healthy young adults. Participants performed a social judgment task in which they had to predict whether or not a virtual peer presented on a computer screen liked them. After the prediction, the actual judgment was shown, and behavioral, electrocortical, and cardiac responses to this judgment were measured. The feedback-related negativity (FRN) was largest after unexpected feedback. The largest P3 was found after the expected “like” judgments, and cardiac deceleration was largest following unexpected “do not like” judgments. Both the P3 and cardiac deceleration were affected by gender—that is, only males showed differential P3 responses to social judgments, and males showed stronger cardiac decelerations. Time–frequency analyses were performed to explore theta and delta oscillations. Theta oscillations were largest following unexpected outcomes and correlated with FRN amplitudes. Delta oscillations were largest following expected “like” judgments and correlated with P3 amplitudes. Self-reported trait neuroticism was significantly related to social evaluative predictions and cardiac reactivity to social feedback, but not to the electrocortical responses. That is, higher neuroticism scores were associated with a more negative prediction bias and with smaller cardiac responses to judgments for which a positive outcome was predicted. Depressive symptoms did not affect the behavioral and psychophysiological responses in this study. The results confirmed the differential sensitivities of various outcome measures to different psychological processes, but the found individual differences could only partly be ascribed to the collected subjective measures.     

Biased allocation of faces to social categories

Three studies show that social categorization is biased at the level of category allocation. In all studies, participants categorized faces. In Studies 1 and 2, participants overallocated faces with criminal features--a stereotypical negative trait--to the stigmatized Moroccan category, especially if they were prejudiced. On the contrary, the stereotype-irrelevant negative trait stupid did not lead to overallocation to the Moroccan category. In Study 3, using the stigmatized category homosexual, the previously used negative trait criminal--irrelevant to the homosexual stereotype--did not lead to overallocation, but the stereotype-relevant positive trait femininity did. These results demonstrate that normative fit is higher for faces with stereotype-relevant features regardless of valence. Moreover, individual differences in implicit prejudice predicted the extent to which stereotype-relevant traits elicited overallocation: Whereas more negatively prejudiced people showed greater overallocation of faces associated with negative stereotype-relevant traits, they showed less overallocation of faces associated with positive stereotype-relevant traits. These results support our normative fit hypothesis: In general, normative fit is better for faces with stereotypical features. Moreover, normative fit is enhanced for prejudiced individuals when these features are evaluatively congruent. Social categorization thus may be biased in itself.     

Individual Differences in Affective Priming Effects: Any Links with Personality and Trait Affectivity?

Processing tendencies refer to individual differences in the automatic processing of affective stimuli. Using the affective priming paradigm one can tap these processing tendencies and differentiate positive and negative affective priming scores. In this study we used a classical evaluative decision task with nouns as primes and adjectives as targets to assess individual differences in positive and negative affective priming in two time points. Using Steyer’s (Steyer et al. in Methods of Psychological Research Online 2(1), 21–33, 1997) true intraindividual change modeling approach, the positive and negative priming scores were defined on a latent level. No significant relationships were found between positive affective priming and trait positive affect nor extraversion, as well as between negative affective priming and trait negative affect and neuroticism. As these findings are not in line with previous research (Robinson et al. in Emotion 10(5), 615–626, 2010; Robinson et al. in Personality and Individual Differences 42(7), 1221–1231, 2007) possible moderating influences are discussed.     

Neuroticism and Responsiveness to Error Feedback: Adaptive Self‐Regulation Versus Affective Reactivity

ABSTRACT Responsiveness to negative feedback has been seen as functional by those who emphasize the value of reflecting on such feedback in self‐regulating problematic behaviors. On the other hand, the very same responsiveness has been viewed as dysfunctional by its link to punishment sensitivity and reactivity. The present 4 studies, involving 203 undergraduate participants, sought to reconcile such discrepant views in the context of the trait of neuroticism. In cognitive tasks, individuals were given error feedback when they made mistakes. It was found that greater tendencies to slow down following error feedback were associated with higher levels of accuracy at low levels of neuroticism but lower levels of accuracy at high levels of neuroticism. Individual differences in neuroticism thus appear crucial in understanding whether behavioral alterations following negative feedback reflect proactive versus reactive mechanisms and processes. Implications for understanding the processing basis of neuroticism and adaptive self‐regulation are discussed.     

Trait anxiety reduces affective fading for both positive and negative autobiographical memories

The affect associated with negative events fades faster than the affect associated with positive events (the Fading Affect Bias; the FAB). The research that we report examined the relation between trait anxiety and the FAB. Study 1 assessed anxiety using the Depression, Anxiety, and Stress Scale; Studies 2 and 3 used the Beck Anxiety Inventory. Studies 1 and 2 used retrospective procedures to probe positive event memories and negative event memories while Study 3 used a diary procedure. The results of all 3 studies showed that increased anxiety was associated with both a lowered FAB and lower overall affect fading for both positive events and negative events. These results suggest that for people free of trait anxiety, the FAB reflects the operation of a healthy coping mechanism in autobiographical memory that is disrupted by trait anxiety.     

Routine cognitive errors: a trait-like predictor of individual differences in anxiety and distress

Five studies (N=361) sought to model a class of errors--namely, those in routine tasks--that several literatures have suggested may predispose individuals to higher levels of emotional distress. Individual differences in error frequency were assessed in choice reaction-time tasks of a routine cognitive type. In Study 1, it was found that tendencies toward error in such tasks exhibit trait-like stability over time. In Study 3, it was found that tendencies toward error exhibit trait-like consistency across different tasks. Higher error frequency, in turn, predicted higher levels of negative affect, general distress symptoms, displayed levels of negative emotion during an interview, and momentary experiences of negative emotion in daily life (Studies 2-5). In all cases, such predictive relations remained significant with individual differences in neuroticism controlled. The results thus converge on the idea that error frequency in simple cognitive tasks is a significant and consequential predictor of emotional distress in everyday life. The results are novel, but discussed within the context of the wider literatures that informed them.

Higher levels of state depression in masculine than in feminine nations

Studies using identical measures have identified different levels of depression in different countries or cultures. Until now, however, explanations for such differences, other than methodological ones, have not been empirically addressed. It was hypothesized and found that soft or feminine nations in which both women and men are offered equal opportunities for the fulfillment of multiple social roles that are associated with good self-rated health would score significantly lower on national depression levels than tough or masculine societies in which such opportunities exist to a clearly lesser extent. Analyses of data collected in 14 nations in Europe (total N>5000) demonstrated that higher scores on Hofstede's national masculinity index and lower ones on national wealth were independent predictors of higher national depression levels. National trait neuroticism did not mediate the relationship between national masculinity and national depression levels.
