Personality and sex differences in emotional responsiveness to positive and negative cognitive stimuli

To investigate the influence of psychoticism (P) and neuroticism (N) on emotional responding, a re-analysis was carried out on subjective and physiological data collected while Ss (n = 50) repeatedly imagined anxious (intrusive) or depressive, and pleasant thoughts or images. High N was associated with a greater negative mood state subsequent to imagining the distressing cognitive stimuli, though there was no relation with physiological reactivity. However, high P scorers did evidence less overall cardiac reactivity and, to a lesser extent, fewer skin resistance responses than low P Ss. The results are discussed in light of the moderating influence that stimulus and response characteristics as well as gender differences can have on the interaction between personality traits and emotional responding.     

Stereotypes and steroids: using a psychobiosocial model to understand cognitive sex differences

To further our understanding of cognitive sex differences, we studied the relationship between menstrual phase (via serum estradiol and progesterone levels) and cognitive abilities and cognitive performance in a sample of medical students in eastern Turkey. As expected, we found no sex differences on the Cattell "Culture Fair Intelligence Test" (a figural reasoning test), with females scoring significantly higher on a Turkish version of the Finding A's Test (rapid word knowledge) and males scoring significantly higher on a paper-and-pencil mental rotation test. The women showed a slight enhancement on the Finding A's Test and a slight decrement in Cattell scores during the preovulatory phase of their cycle that (probably) coincided with a rise in estrogen. There were also small cycle-related enhancements in performance for these women on the mental rotation test that may reflect cyclical increases in estrogen and progesterone. Additional analyses showed an inverted U-shaped function in level of estradiol and the Cattell Test. Finally, for women who were tested on Day 10 of their menstrual cycle, there was a negative linear relationship between their Cattell scores and level of progesterone. Stereotypes about the cognitive abilities of males and females did not correspond to performance on the mental rotation or Finding A's Test, so the sex-typical results could not be attributed to either stereotype threat or stereotype activation. For practical purposes, hormone-related effects were generally small. Variations over the menstrual cycle do not provide evidence for a "smarter" sex, but they do further our understanding of steroidal action on human cognitive performance.     

Interparental conflict and adolescent emotional security across family structures

This study investigated whether interparental conflict was differentially related to forms of emotional security (i.e., family, interparental, parent–child) and whether forms of emotional security were differentially associated with mental health problems for adolescents in married versus divorced/separated families. Participants were 1032 adolescents (ages 10–15; 51% male, 49% female; 82% non-Hispanic White, 9% Black/African American, 5% Hispanic, 2% Asian or Pacific Islander, 2% Native American) recruited from a public school in a middle-class suburb of a United States metropolitan area. We used multiple group multivariate path analysis to assess (1) associations between interparental conflict and multiple measures of emotional insecurity (i.e., family, interparental, and parent–child), (2) associations between measures of emotional insecurity and internalizing and externalizing problems, and (3) moderation effects of parent–child relationships. The patterns of association were similar across family structures. A high-quality parent–child relationship did not mitigate the harmful effects of interparental conflict on emotional insecurity or mental health problems. Findings suggest that regardless of family structure, emotional security across multiple family systems may be a critical target for intervention to prevent youth mental health problems, in addition to interventions that reduce conflict and improve parent–child relationships.     

Age differences in emotional reactivity: the sample case of sadness

Past studies have suggested that the intensity of subjective reactions to emotion-arousing stimuli remains stable, whereas the magnitude of autonomic reactions declines with age. The goal of the present studies was to investigate whether this evidence will generalize to newly edited films dealing with age-relevant themes such as the loss of loved ones. In Study 1, greater self-reported sadness was found in older than in younger adults in response to all films. Findings of Study 2, which were based on an independent sample, replicated those of Study 1. In addition, 6 indicators of autonomic nervous system activity were assessed. Young and old adults did not differ in their autonomic reactions to the films. This evidence suggests that when older people are exposed to stimuli featuring themes that are relevant to their age group, they show greater subjective and physiological reactions than would be expected on the basis of past research.     

An investigative biobehavioral approach to sex differences in cognitive functioning

Advances in our biological understanding and control of cognitive functioning have not been matched in the behavioral realm. The bio-behavioral approach outlined in this paper helps to close this bio-behavioral gap by aiming for a taxonomic precision in psychology that is comparable to that in physiology. The approach is applied to the phenomenon of group sex differences, and is illustrated by referring to three sets of recently reported findings: (a) interactive effects of nicotine and sex on the trait of cognitive style; (b) sexually dimorphic cognitive style in rats and the involvement of nitric oxide as a potential physiological mechanism and (c) sexually dimorphic phasic arousal change induced by smoking a cigarette following deprivation.     

Individual differences in cognitive control over emotional material modulate cognitive biases linked to depressive symptoms

Deficient cognitive control over emotional material and cognitive biases are important mechanisms underlying depression, but the interplay between these emotionally distorted cognitive processes in relation to depressive symptoms is not well understood. This study investigated the relations among deficient cognitive control of emotional information (i.e. inhibition, shifting, and updating difficulties), cognitive biases (i.e. negative attention and interpretation biases), and depressive symptoms. Theory-driven indirect effect models were constructed, hypothesising that deficient cognitive control over emotional material predicts depressive symptoms through negative attention and interpretation biases. Bootstrapping analyses demonstrated that deficient inhibitory control over negative material was related to negative attention bias which in turn predicted a congruent bias in interpretation and subsequently depressive symptoms. Both shifting and updating impairments in response to negative material had an indirect effect on depression severity through negative interpretation bias. No evidence was found for direct effects of deficient cognitive control over emotional material on depressive symptoms. These findings may help to formulate an integrated understanding of the cognitive foundations of depressive symptoms.     

Individual differences in hedonic capacity,depressed mood,and affective states predict emotional reactivity

Identifying factors that contribute to inter-individual differences in emotional reactivity is central to understanding the basic mechanisms that give rise to adaptive emotion reactivity and to disruptions that may occur in psychopathology. The current study related emotional reactivity in an unselected young adult sample (N?=?101) to individual difference factors relevant to emotional functioning and mood pathology, specifically anhedonia, depressed mood, and current affective state. To assess emotional reactivity, participants rated their emotional responses to 100 pictures from the International Affective Picture System. Increased self-reported anhedonia (i.e. reduced hedonic capacity) predicted blunted emotional reactivity to both positive and negative images, relative to neutral images, while elevated depressed mood predicted potentiated emotional reactivity to negative vs. neutral images. Anhedonia also accounted for far greater variance in emotional reactivity than depressed mood. Further, more positive affective state predicted potentiated reactivity to positive versus neutral images while more negative affective state predicted potentiated reactivity to negative versus neutral images beyond effects of anhedonia and depressed mood. The current study identified separable effects of anhedonia, depressed mood, and current affect on emotional reactivity.     

Mood induced cognitive and emotional reactivity, life stress, and the prediction of depressive relapse

This study examined a group of participants who were fully remitted from a previous episode of major depressive disorder, and evaluated the role of cognitive and emotional reactivity to a mood challenge, and life stress in the prediction of relapse. Fifty-two participants were evaluated during remission, and their reactivity (i.e., change in dysfunctional attitudes and emotional state) to a depressed mood induction was evaluated. The cohort was followed up 12 months after the initial assessment. Thirty-five percent of the sample experienced a relapse during the follow-up period. Relapse was predicted by higher rates of life stress, and lower levels of emotional reactivity (specifically less reduction in happiness) to the mood induction during the initial assessment. Cognitive reactivity to the mood induction did not predict relapse, nor did the interaction between cognitive reactivity and life stress. These findings are discussed in terms of recent literature suggesting that depression is associated with insensitivity to emotion context, such that depressed individuals display blunted emotional responses to affective stimuli, including sadness-inducing stimuli. These findings suggest that insensitivity to emotional context may also be a characteristic of euthymic individuals at risk of relapse.     

Content and person effects in media research: Studying differences in cognitive,emotional, and arousal responses to media content

ABSTRACT

Cognitive, emotional, and arousal responses to media content stem from two sources of variation: differences in content and differences between individuals. Although the first source of variation (content effects) has been well-studied, individual differences (person effects) in responses to media are investigated much less within communication science. To help build this comparatively thin area of scholarship, this study investigated how four theoretically relevant variables (need for cognition, affective empathy, sensation seeking, and sensory processing sensitivity) affected responses to positively and negatively valenced media entertainment. In a within-subjects design, 243 youth aged 7–15 years (49.4% female) responded to a positive and negative film clip using both self-reported and physiological measures (heart rate and skin conductance), while parents reported on individual differences. Multilevel analysis was used to distinguish between media content effects and individual differences in responses. Results showed that more variation in responses was due to differences between participants than to differences between stimuli. However, need for cognition, affective empathy, sensation seeking, and sensory processing sensitivity did not significantly explain this between-participant variation in responses. Several conceptual and methodological take-aways are offered to advance our understanding of the relationships between stable individual differences and state responses to media.     

Mindfulness-based cognitive therapy improves emotional reactivity to social stress: results from a randomized controlled trial

The high likelihood of recurrence in depression is linked to a progressive increase in emotional reactivity to stress (stress sensitization). Mindfulness-based therapies teach mindfulness skills designed to decrease emotional reactivity in the face of negative affect-producing stressors. The primary aim of the current study was to assess whether Mindfulness-Based Cognitive Therapy (MBCT) is efficacious in reducing emotional reactivity to social evaluative threat in a clinical sample with recurrent depression. A secondary aim was to assess whether improvement in emotional reactivity mediates improvements in depressive symptoms. Fifty-two individuals with partially remitted depression were randomized into an 8-week MBCT course or a waitlist control condition. All participants underwent the Trier Social Stress Test (TSST) before and after the 8-week trial period. Emotional reactivity to stress was assessed with the Spielberger State Anxiety Inventory at several time points before, during, and after the stressor. MBCT was associated with decreased emotional reactivity to social stress, specifically during the recovery (post-stressor) phase of the TSST. Waitlist controls showed an increase in anticipatory (pre-stressor) anxiety that was absent in the MBCT group. Improvements in emotional reactivity partially mediated improvements in depressive symptoms. Limitations include small sample size, lack of objective or treatment adherence measures, and non-generalizability to more severely depressed populations. Given that emotional reactivity to stress is an important psychopathological process underlying the chronic and recurrent nature of depression, these findings suggest that mindfulness skills are important in adaptive emotion regulation when coping with stress.     

Age and gender differences in cardiac reactivity and subjective emotion responses to emotional autobiographical memories

This research reports age and gender differences in cardiac reactivity and subjective responses to the induction of autobiographical memories related to anger, fear, sadness, and happiness. Heart rate (HR) and subjective state were assessed at baseline and after the induction of each emotion in 113 individuals (61 men, 52 women; 66% European American, 34% African American) ranging in age from 15 to 88 years (M = 50.0; SD = 20.2). Cardiac reactivity was lower in older individuals; however, for anger and fear, these age effects were significantly more pronounced for the women than the men. There were no gender differences in subjective responses, however, suggesting that the lower cardiac reactivity found among older people is dependent on gender and the specific emotion assessed.     

Automatic activation of self-discrepancies and emotional syndromes: when cognitive structures influence affect

Different types of self-discrepancies are associated with different negative affects. Two studies were conducted to determine whether automatic activation of specific actual-self: self-guide mismatches, as cognitive structures, would induce distinct emotional states. Subjects possessing significant discrepancies between their actual self and either their ideal self-guide (attributes that someone wishes or hopes the person would possess) or their ought self-guide (attributes that someone believes the person has the duty or obligation to possess) responded verbally to an audiotape while "thinking about other people." Study 1 involved two kinds of priming attributes: self-relevant and yoked (another subject's self-relevant attributes). Activating mismatches induced momentary syndromes of dejection (sadness, decreased arousal) in ideal-discrepant subjects but induced agitation (nervousness, increased arousal) in ought-discrepant subjects. In Study 2, subjects were randomized to either self-relevant/nondiscrepant, self-discrepant, or yoked priming. The findings of Study 1 were replicated for the self-discrepant priming condition alone. Results indicate that (a) mismatches constitute cognitive structures and (b) automatic activation of different mismatches via contextual priming induces distinct types of emotional discomfort.     

Evidence for conditional sex differences in emotional but not in sexual jealousy at the automatic level of cognitive processing

The two evolutionary psychological hypotheses that men react more jealous than women to sexual infidelity and women react more jealous than men to emotional infidelity are currently controversial because of apparently inconsistent results. We suggest that these inconsistencies can be resolved when the two hypotheses are evaluated separately and when the underlying cognitive processes are considered. We studied jealousy with forced‐choice decisions and emotion ratings in a general population sample of 284 adults aged 20–30 years using six infidelity dilemmas and recordings of reaction times. The sex difference for emotional jealousy existed for decisions under cognitive constraint, was also evident in the decision speed, increased for faster decisions, and was stronger for participants with lower education. No evidence for a sex difference in sexual jealousy was found. Our results support the view of a specific female sensitivity to emotional infidelity that canalizes the development of an adaptive sex difference in emotional jealousy conditional to the sociocultural environment.

The impact of cortisol reactivity to acute stress on memory: sex differences in middle-aged people

Stress has been identified as a main factor involved in the cognitive changes that occur during the aging process. This study investigated sex differences in the relationship between the magnitude of the acute stress-induced salivary cortisol response and memory performance among middle-aged people. To this end, 16 men and 16 women (aged 54-72 years) were exposed to the Trier Social Stress Test and a control condition in a crossover design. Afterwards their memory performance was measured using a standardized memory test (Rey's Auditory Verbal Learning Test). Only among women, there was an acute impact of stress on memory performance and a significant relationship between a higher cortisol response to the stressor and poorer memory performance in both the stress and control conditions. Additionally, a poorer memory performance was related to earlier timing of sexual maturation (age at menarche), which was also marginally related to higher cortisol reactivity to stress. These results confirm that sex is a critical factor in the relationship between cortisol and poor memory performance. Furthermore, the findings emphasize a strong link between the individual cortisol response to stress and memory functioning among postmenopausal women.     

Attitudes to sex, sexual behaviour and enjoyment of humour

Freudian (1905 Wien; Der Witz und seine Beziehung zum Unbewuβten. Deuticke) and Salience (Goldstein, Suls and Anthony, 1972; The Psychology of Humor. Academic Press, New York) theory make opposite predictions about the effects of attitudes to sex and sexual behaviour on appreciation of sex humour. Male and female students (N=115) answered a questionnaire of attitudes toward sex, a sexual behaviour inventory (Eysenck, 1976; Sex and Personality. Open Books, London) and a humour test. The results generally supported a positive correlation between appreciation of sex humour and the sex scales (sexual libido, satisfaction, experience and pleasure), although the resulting pattern was very complex. Separation of sex humour according to the jokes structure yielded different predictor patterns. Funniness of humour based on nonsense correlated most frequently and most highly with the sex scales libido, experiences and pleasure. Low sexual satisfaction, low permissiveness, and prudishness were correlated with aversiveness of all types of humour. Furthermore, it was hypothesized that these variables are better predictors of enjoyment of sexual humour than the more general factors of conservatism and toughmindedness (T) which turned out to be potent predictors in a recent study (Ruch and Hehl, 1986; Person. individ. Diff. 7, 861–874). It turned out that the predictive sex scales were located on the toughmindedness axis and were thus as predictive of sex humour as T itself. A refinement of the salience hypothesis was undertaken.     

Sensitivity to sensoriprocessing, self-discrepancy, and emotional reactivity of collegiate athletes

This study investigated how differences between athletes who scored low and high on sensoriprocessing sensitivity apply self-discrepancies and emotional reactions to competitive sporting events. Two hypotheses were proposed: The High Sensitivity group (n = 33) would score higher for anxiety, guilt, and shame, and lower on pride and report more stress attributed to self-discrepancies than the Low Sensitivity group (n = 32) following competitive sports events. Collegiate varsity athletes were administered the High Sensitivity Scale prior to competition and completed the Selves Questionnaire and the Goal Congruent and Incongruent Emotion Scale immediately after competition. Scores for the High Sensitivity Scale were used to separate athletes into high and low sensitivity groups. A multivariate analysis of variance and subsequent univariate analyses indicated that the High Sensitivity group reported higher scores on anxiety, shame, and stress than the Low Sensitivity group. This was interpreted as reflecting differences between both ideal and ought self-discrepancies.     

Extraversion and emotional reactivity

Six mood induction studies and a meta-analysis were conducted to test 2 models of the extraversion-pleasant affect relation. The affect-level model suggests that extraverts should be happier than introverts in both neutral and positive mood conditions. The reactivity model posits that extraverts react particularly strongly to pleasant stimuli and that they should be happier than introverts only in positive conditions. In all studies, extraverts failed to exhibit greater emotional reactivity when pleasantness items were analyzed. When activated positive affect items were analyzed, results were mixed. The meta-analysis confirmed that there is only a slight reactivity effect overall, and this effect emerges only in activated positive affect items. Furthermore, the meta-analysis showed that the correlation in neutral conditions is strong enough to support the affect-level model.     

Developmental change and intraindividual variability: relating cognitive aging to cognitive plasticity, cardiovascular lability, and emotional diversity

Repeated assessments obtained over years can be used to measure individuals' developmental change, whereas repeated assessments obtained over a few weeks can be used to measure individuals' dynamic characteristics. Using data from a burst of measurement embedded in the Berlin Aging Study (BASE; Baltes & Mayer, 1999), we illustrate and examine how long-term changes in cognitive ability are related to short-term changes in cognitive performance, cardiovascular function, and emotional experience. Our findings suggest that "better" cognitive aging over approximately 13 years was associated with greater cognitive plasticity, less cardiovascular lability, and less emotional diversity over approximately 2 weeks at age 90 years. The study highlights the potential benefits of multi-time scale longitudinal designs for the study of individual function and development.
