Extraversion, sensation seeking and electrodermal response: Probing a paradox

Extraversion and psychoticism are thought to relate inversely to electrodermal response amplitude. Paradoxically, sensation-seeking scales, which correlate positively with extraversion and psychoticism, have shown a positive relation to electrodermal response amplitude. In the present inquiry, inverse relationships were obeserved for extraversion and psychoticism with the electrodermal response to visual stimuli. Sensation seeking was also negatively related to the magnitude of the initial electrodermal response to pictures. A lowered response to words for low sensation seekers was observed that appeared to be influenced by skin conductance level.     

The link between sensation seeking and aggression: a meta-analytic review

Substantial empirical evidence supports low resting heart rate (HR) as the best replicated psychophysiological correlate of aggression [Ortiz and Raine, 2004]; however, researchers continue to debate the explanatory mechanisms of the phenomenon. Sensation seeking has been proposed as a possible outcome of low resting HR that may lead to aggressive tendencies but findings have been inconsistent in terms of showing a relationship between sensation seeking and aggression. A meta-analysis was conducted on 43 independent effect sizes, from studies with a total of 32,217 participants, to test the hypothesis that sensation seeking would be positively related to aggression across studies. A significant overall effect size was found (d = .1935, P<.001), supporting the hypothesis. Moderator analyses revealed that the relationship differed based on participant and methodological characteristics, such as participant age and the nature of the aggression measurement; however, these conclusions are limited by the uneven number of studies in many of the moderator classes. Overall, the findings provide support for higher levels of aggression in high sensation seekers and have theoretical implications for arousal theory. Further research on the links between arousal, sensation seeking and aggression can inform clinicians about potential interventions.     

Procrastination,consideration of future consequences,and episodic future thinking

Despite the intrinsic temporal nature of procrastination, little research has examined the link between this form of self-regulatory failure and the consideration of future consequences, and no study has addressed the link between procrastination and episodic future thinking. The aim of the present study was to explore these relationships. Participants were asked to project themselves into possible future events and to rate the amount of sensory-perceptual details and autonoetic consciousness associated with their representations. They were also asked to complete questionnaires that assessed procrastination, the consideration of future consequences, and negative affect. Results showed that both the consideration of future consequences and episodic future thinking were associated with procrastination, and in particular with procrastination-related decision making abilities and procrastination-related motivational dispositions, respectively.     

Boredom proneness in anger and aggression: effects of impulsiveness and sensation seeking

The present study was a replication and extension of Rupp and Vodanovich’s (1997) work on the role of boredom proneness in anger expression and aggression. In addition to replicating their primary analyses, impulsiveness and sensation seeking were included to determine the potential impact of these variables on the relationships between boredom proneness and anger and aggression. Two hundred and twenty-four college student volunteers completed measures of boredom proneness, impulsiveness, sensation seeking, anger expression, and aggression. Findings were consistent with Rupp and Vodanovich (1997) but demonstrated more pervasive effects of external boredom proneness on aggression. Hierarchical multiple regression analyses demonstrated that the relationships between external boredom proneness and trait anger, anger expression/control, and aggression persisted even after accounting for impulsiveness and sensation seeking. Boredom due to a lack of external stimulation predicted one’s propensity to experience anger, maladaptive anger expression, aggression, and deficits in anger control.     

A paradox of support seeking and rejection among the stigmatized

Individuals perceiving stigma may be unwilling to seek support directly. Instead, they may use indirect strategies due to fear of rejection. Ironically, indirect seeking leads to unsupportive network responses (i.e., rejection). In Study 1, data collected from structured interviews of a sample of U.S. women in poverty (N= 116) showed that perceived poverty‐related stigma was related to increased fear of rejection, which in turn partially mediated perceived stigma and indirect seeking. In Study 2, data gathered from structured interviews of a sample of U.S. abused women (N= 177) revealed that perceived abuse‐related stigma was linked to increased indirect seeking, which in turn related to increased unsupportive network responses. By contrast, direct support seeking was related to increased supportive and decreased unsupportive responses.     

Personality correlates of revenge‐seeking: Multidimensional links to physical aggression,impulsivity, and aggressive pleasure

People differ in how much they seek retribution for interpersonal insults, slights, rejections, and other antagonistic actions. Identifying individuals who are most prone towards such revenge‐seeking is a theoretically‐informative and potentially violence‐reducing endeavor. However, we have yet to understand the extent to which revenge‐seeking individuals exhibit specific features of aggressiveness, impulsivity, and what motivates their hunt for retribution. Toward this end, we conducted three studies (total N = 673), in which revenge‐seeking was measured alongside these other constructs. Analyses repeatedly demonstrated that revenge‐seeking was associated with greater physical (but not verbal) aggressiveness, anger, and hostility. Revenge‐seeking's link to physical aggression was partially accounted for by impulses toward enjoying aggression and the tendency to use aggression to improve mood. Dominance analyses revealed that sadism explained the most variance in revenge‐seeking. Revenge‐seeking was associated with greater impulsive responses to negative and positive affect, as well as greater premeditation of behavior. These findings paint a picture of revenge‐seekers as physically aggressive curators of anger, whose retributive acts are performed with planned malice and motivated by the act's entertaining and therapeutic qualities.

     

Reducing intergroup conflict through the consideration of future consequences

Basic social psychological research has suggested several interventions to reduce intergroup conflict. Most of these interventions, however, have been indirect and impractical to implement outside laboratory settings. Although past research has demonstrated that indirect manipulations of the consideration of future consequences reduce intergroup competition, no study of interindividual–intergroup discontinuity has tested this assumption with a direct manipulation. The present study found that when participants (individuals and members of groups) interacting in an iterated prisoner's dilemma game (PDG) were asked to predict how their opponent's choice on a second trial would be affected by their own choice on an initial trial, intergroup competition was reduced while interindividual competition remained low regardless of the manipulation. On a practical level, implications of this study provide a simple and easily implemented solution to reducing intergroup conflict in non‐laboratory situations.

The prediction of drug use among college students from MMPI, MCMI, and sensation seeking scales

This study examines the ability of five self-report assessment measures to predict college students' drug use across 12 pharmacological drug categories. Subjects were 125 female and 61 male university undergraduate students. The test battery included the following instruments: the Psychopathic Deviancy (Pd) scale of the Minnesota Multiphasic Personality Inventory (MMPI); the MacAndrew Alcoholism scale (MAC), a special scale of the MMPI; the Sensation Seeking Scale (SSS); the Millon Alcohol Abuse Scale; and the Millon Drug Abuse Scale. Scores from these instruments were utilized in linear combinations to predict individual drug use outcomes as well as polydrug versus single drug use patterns. The drug categories included in this investigation are coffee, tobacco, alcohol, marijuana, tranquilizers, depressants, amphetamines, LSD, other hallucinogens, solvents, narcotics, and cocaine. Results demonstrate significant and meaningful relationships between predictors and drug use levels among college students. Weighted equations derived from linear discriminant function analyses were generally capable of accurately classifying subject's drug use levels across drug categories and in discriminating single drug use from polydrug use patterns. Typically, the Sensation Seeking Scale entered as the most powerful predictor of substance use and abuse.     

Demographic influences in sensation seeking and expressions of sensation seeking in religion, smoking and driving habits

A large sample of readers of a popular psychology magazine took the Sensation Seeking Scale (form V) and filled out a personal data form. The information in the data form was used to examine the relationship between SSS scores and demographic and experience variables. Sex and age showed strong relationships with the SSS. Education and occupation of the subjects and their parents showed lesser relationships with the SSS and primarily in females. Non-believers in conventional religion and infrequent church-goers had higher SSS scores than those who identify with such religions and attend church regularly. Smokers had higher scores than non-smokers although the relationship with amount of smoking was not a linear one. Driving habits of speeding related strongly to sensation seeking in a linear fashion.     

Examining profiles of the big five and sensation seeking among competitive climbers

The present study sought to identify distinct personality profiles in competitive climbers (N = 331, Mean age = 29.85, SD = 10.92), and also sought to explore whether these climbers differed in their sensation seeking tendencies based on these personality profiles. Employing a cross-sectional design, participants completed measures of the big five personality dimensions (agreeableness; conscientiousness; extraversion; neuroticism; openness to experience) and sensation seeking (boredom susceptibility; experience seeking; disinhibition; thrill and adventure seeking). Latent profile analysis identified four distinct big five personality profiles (Curious and Impulsive; Emotionally Unstable; Healthy; and Measured and Compliant). MANCOVA and follow-up ANCOVAs demonstrated significant differences between the four personality profiles in relation to thrill and adventure seeking, experience seeking, and disinhibition. The findings suggest that the identification of distinct personality profiles using a person-centred approach is a useful way of distinguishing and optimizing typical behaviors and preferences in adventure sports in the future.     

Self-prospection and energization: The joint influence of time distance and consideration of future consequences

The way people envision their future (self-prospection) plays a key role in the energization required to pursue desired goals. We proposed that energization is determined by time distance from the imagined future-self and the individual’s consideration of future consequences (CFC). We hypothesized that, when imagining their distant (vs. near) future-self, individuals higher on CFC (i.e., those who construe a stronger link between present and future selves), would report greater energization. Participants completed the CFC scale, imagined their distant or near future-self, and reported their energy level. Imagining distant (vs. near) future-self fostered energy among participants higher on CFC (Experiments 1–2), an effect mediated by vividness of self-representations (Experiment 2). Self-prospection has implications for current states, and specifically for felt energy.     

Eat now,exercise later: The relation between consideration of immediate and future consequences and healthy behavior

In light of the current obesity epidemic, individual choices for food and exercise should be understood better. Consideration of the immediate and future consequences of these choices (i.e., time orientation) can be an important predictor of eating and exercising behavior. The objective was to show that behavior-specific time orientation differentially predicts eating and exercising behavior. Two studies were conducted among students (N = 55) and the general public (N = 165). Participants completed two adapted versions (for food and exercise) of the Consideration of Future Consequences Scale (CFC), each consisting of the subscales CFC-future and CFC-immediate. Thereafter they reported their eating and exercising behavior. Study 1 showed that CFC-food, but not CFC-exercise, predicted eating behavior. Similarly, both studies showed that CFC-exercise, but not CFC-food, predicted exercising behavior. Moreover, eating behavior was predicted by CFC-food/immediate, whereas exercising behavior was predicted by CFC-exercise/future. In conclusion, behavior-specific time orientation predicts behavior within a behavioral domain but less well across behavioral domains. Additionally, consideration of immediate and future consequences differentially predict behavior across behavioral domains. In order to predict behavior, time orientation is measured best at a behavior-specific level.     

Field dependence,sensation seeking and driving behaviour

The present study attempted to relate field dependence-independence (FDI) to accident involvement and perceived causes of accidents as well as to trace these relationships to the sensation-seeking (SS) tendency of the field-dependent driver. In addition, the concomittant effects of internal/external locus of control (IE) were studied. Subjects (N=285) filled out a questionnaire assessing their level of FDI, SS, IE, number of accidents, as well as the attributed importance of various possible causes of their last accident. The obtained results show no relationship between FDI and SS and either the number of accidents or the importance attributed to various causes of accidents. Significant relationships were, however, obtained between FDI and SS and seat-belt use and SS and speed on the highway.     

Disinhibitory sensation seeking,personality and gonadal hormones

The study compared normal males who scored at the extremes of Disinhibition (a subscale of the Sensation Seeking Scale) on gonadal hormones. High disinhibitors were higher than lows on testosterone, estradiol and estrone, but not on progesterone. A broader range of personality traits, attitudes and experience was factor analyzed and correlated with the hormone measurements. Two large factors were found: (1) stable extraversion vs neurotic introversion; (2) social deviancy vs social conformity. Testosterone loaded positively on the stable extraversion factor and estradiol loaded on the social deviancy factor. Measures of sensation seeking, impulsivity and heterosexual experience tended to correlate positively with both testosterone and estradiol, and persons low on both of these hormones were characterized by a high degree of self control and social conformity.     

Coping with war captivity: The role of sensation seeking

This study examines the implication of both sensation seeking and the subjective appraisal of captivity in the long-term adjustment of ex-prisoners of war (ex-POWs). 164 Israeli ex-POWs and 184 comparable controls were studied, 18 years after their participation in the Yom Kippur War. The findings indicate that high-sensation seekers adjusted better than low-sensation seekers to the stresses of captivity. Low-sensation-seeking ex-POWs reported more PTSD symptoms, more severe psychiatric symptomatology, and more intense intrusive and avoidance tendencies. High- and low-sensation-seeking POWs differed also in feelings when taken prisoner, subjective assessment of suffering in prison, ways of coping with prison, and emotional states during captivity. The present study supports the postulation that sensation seeking is an important stress-buffering personal resource. The role of coping styles in long-term adjustment following war captivity is discussed.     

Life change and the sensation seeking motive

College undergraduates were administered the Life Experiences Survey, the Discomfort scale of the Psychological Screening Inventory, and the most recent version of the Sensation Seeking Scale. The findings did not replicate Smith et al.'s results concerning the role that sensation seeking plays in the relationship between negative life change and psychological distress. However, the data suggest that the sensation seeking motive is a causal variable that is predictive of recent life events that college students have experienced, and that future life-stress research should examine the occurence of controllable life events as a function of subjects' personality traits.     

A paradox of support seeking and support response among gays and lesbians

Individuals that perceive stigma surrounding their identity and fear rejection of support requests may experience a paradox whereby they seek support indirectly from support networks (friends and family) to avoid rejection and are met with unsupportive responses. This study extended this paradox to sexual minorities using survey data from a sample of 133 individuals self‐identified as gay and lesbian. Results of structural equation modeling showed self‐stigma and fear of support rejection linked to increased indirect support seeking, which in turn explained unsupportive network responses, providing support for a paradox among gays and lesbians. Findings may have implications for interventions to improve support exchanges in the lives of sexual minorities.     

Relation of transliminality and sensation seeking

The Revised Transliminality Scale and Zuckerman's Sensation Seeking Scale (Form V) were administered to 83 psychology undergraduates. Weak positive correlations suggested that participants scoring high on the Transliminality Scale tended to be more experience seeking and, overall, more inclined to score sensation seeking.     

Motion sickness history, food neophobia, and sensation seeking

Motion sickness is believed to be caused by conflicting sensory signals, a situation that mimics the effects of ingesting certain toxins. Thus, one might suspect that individuals who have experienced a relatively high frequency of motion sickness may be particularly vigilant about avoiding anything that produces nausea, induding potentially nauseating toxins. Consequently, they may be more resistant to trying new foods, i.e., be more food neophobic, since unfamiliar foods can have unexpected adverse effects due to toxins or allergens. Likewise, many highly stimulating experiences can trigger motion sickness, so individuals who are more susceptible may be more prone to avoid such experiences, i.e., be less sensation seeking. Finally, it was expected that food neophobia would be more frequent in individuals low on sensation seeking tendencies. Self-reported motion sickness history in 308 adults (M= 18.8 yr.; SD = 1.6) was correlated with scores on the Arnett Inventory of Sensation Seeking and the Food Neophobia Scale. As predicted, greater history of motion sickness was associated with lower Sensation Seeking scores. Food Neophobia was not correlated with motion sickness history but, as expected, was negatively correlated (r = -.42) with scores on Sensation Seeking. Further research is recommended that measures actual sensitivity to motion sickness.     

Serious delinquent behavior,sensation seeking,and electrodermal arousal

Low tonic skin conductance level (SCL) has been related, inconsistently, to both delinquency and sensation-seeking. This study tests the hypothesis that there is an interaction such that high sensation seeking delinquents, in particular, have low SCLs. Participants consisted of 335 boys from the Pittsburgh Youth Study classified as serious delinquents or controls based upon 10 years of prospectively collected self-report delinquency data. Participants' skin conductance was evaluated at age 16 along with several personality and neuropsychological measures. Both delinquency and sensation seeking were characterized by low SCL. However, there was no evidence to suggest that the presence of both of these factors together lead to especially low skin conductance levels. This finding is not explained by differences between the groups on measures of negative emotionality, IQ, socioeconomic status, or impulsivity.
