A genetic and environmental analysis of sensation seeking

The genetic and environmental contributions to the trait of sensation seeking were analyzed using the responses of 422 pairs of twins to the Sensation Seeking Scale (Form IV). The biometrical method of Jinks and Fulker was applied to the data. The data fit the model indicating the likelihood of a predominantly additive gene action controlling the general trait. The heritability figure of 58% (69% of the reliable variance) was quite high for a personality trait. Data from other studies suggest that the heritability of the personality trait rests upon specific inherited biological traits, such as the biochemicals of the brain and gonadal hormones which affect arousability of the central nervous system and relevant traits, such as mood, impulsivity, risk taking, and sociability.     

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.     

Affect and sensation seeking

The notion that affective responses differentiate high from low sensation-seekers was investigated. Male subjects with extremely high (N=13) or low (N=13) scores on Form V of the Sensation Seeking Scale (SSS) were presented with tones of 60, 80, and 100 dB in successive blocks of 10 tones each. Although measures of arousal (verbal self-reports and physiological measures of the orienting response) did not differentiate between high and low sensation-seekers, a self-report measure of pleasure did: Whereas reported pleasure of the low sensation-seekers began high and declined as tones became successively louder, the reported pleasure of the high sensation-seekers remained more constant across the blocks of tones.The research on which this paper was based was supported by Grant MT-4511 from the Medical Research Council of Canada to Robert Hare.     

Headache and sensation seeking

According to the cognitive theory of sensation seeking, headache sufferers were predicted to score lower than controls on Zuckerman's Sensation Seeking Scale. 26 subjects who experienced chronic headaches scored significantly lower than a group of 26 controls. The relationships between the Sensation Seeking Scale and a number of personality tests are described. Replication of the findings on this scale with headache patients is encouraged as well as exploration of other personality dimensions which show significant relations with sensation seeking.     

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.     

Predicting high risk sexual behaviour in heterosexual and homosexual men: the roles of impulsivity and sensation seeking

Impulsivity and sexual sensation seeking were examined as personality correlates of high risk sexual behaviour — unprotected sex with multiple partners — in samples of heterosexual (n=112) and homosexual (n=104) men. Among heterosexuals, both personality variables were associated with frequency of unprotected sex but only sexual sensation seeking was associated with number of sex partners. Sexual sensation seeking also mediated the association between use of drugs other than alcohol and number of sex partners. Among homosexuals, no personality or substance use variables predicted high risk sexual behaviour. Implications of the findings for the study of determinants of sexual risk-taking are discussed.     

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.     

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.     

Explorations into the biochemistry of sensation seeking

This investigation sought to determine to what extent, if any, the personality trait of sensation seeking is related to blood plasma levels of monoamine oxidase (MAO) and dopamine beta hydroxylase (DBH). The experimental group consisted to 19 ski instructors/petrolmen (8 females and 11 males) aged 18–19 yr. The control group was made up of 21 New Mexico Highlands University (NMHU) students (11 females and 10 males) also aged 18–39 yr. The experiment was divided into morning and afternoon sessions. During the morning session the Ss completed the Sensation Seeking Form V, the Sensation of blood by venipuncture. A second blood sample was taken during the afternnon session. The skier group scored significantly higher on those personality measures designed to identify the sensation seeking personality, and the skiers also had significantly higher DBH levels than the nonskiers [F(1, 36)=16.62, P=0.0002]. A possible explanation for the high DBH levels among skiers is that at the time of the blood sampling, the skiers were in a more stressful situation and they had also engaged in vigorous physical exercise.     

Individual differences in sensation seeking and attentional ability

Evidence is provided that high scores on the Zuckerman Sensation Seeking Scale are associated in the normal population with good focused-attention performance and poor distributed-attention performance. Focused-attention performance is assessed as the ability to select relevant information while ignoring irrelevant information, and distributed-attention performance is assessed as the ability to carry out concurrently two independent complex tasks. It is hypothesized that the observed disposition of attentional performance reflects differential patterns of arousal in individuals with high and low Sensation Seeking scores.     

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.     

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.     

On the distinction between violations and errors: sensation seeking associations

In this study about 700 young adult Swedish drivers aged 18–27 yr responded to a questionnaire on sensation seeking, the tendency to engage in risky behaviours, four types of aberrant driving behaviour (violations, mistakes, inattention and inexperience errors), traffic offences and accident involvement. These results suggest, not unreasonably, a differential relationship between different aspects of sensation seeking and aberrant driving behaviour. Whereas sensation seeking explained a large part of the variation in the violations factor, it accounted for very little of the variance in the other aberrant driving behaviour factors. This finding corresponds reasonably well with a hypothesis calling for a distinction between violations and errors. Still after controlling for the effect of exposure the self-reported accidents was associated with self-reported violations and driving mistakes. Self-reported traffic offences was associated with violations. Consequently, the violations and mistakes factors proved to be stable predictors of offences and accidents. The hierarchical approach taken in this study also shows how the construct of sensation seeking may be associated with aberrant driving behaviour.     

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.     

Social norms for the desirability of sensation seeking

The level of sensation seeking most socially desirable was determined by informing undergraduate students that they were to respond to Zuckerman's (1979) Sensation Seeking Scale (Form V) twice, once under the usual instructions and once under instructions to create the best possible image for someone they found attractive. Scores under the best image instructions (M = 23.85, SD = 6.52) were higher than scores under the usual instructions (M = 18.00, SD = 5.40). The scores produced under the best image instructions were independent of scores produced under the usual instructions. These data are interpreted as evidence of norms for the social desirability of sensation seeking.Scores from present study were compared to baseline data for this population. Under the usual instructions, males scored lower than baseline, a difference not observed for females. Under the best image instructions, females scored higher than baseline, a difference not observed for males. This evidence regarding the susceptibility of the scale scores to instructional manipulations was discussed.     

The four dimensions of sensation seeking: a confirmatory factor analysis

The factor structure of the Sensation Seeking Scale, Form V was obtained for a large Canadian sample consisting of 299 males and 439 females. Constrained maximum likelihood confirmatory factor analyses demonstrated that both male and female factors correspond to the four-dimensional model of sensation seeking postulated by Zuckerman (1979). These findings are in close agreement with previous reports of the factor structure and psychometric indices obtained with other cultural and national groups. However, the four factors accounted for only 21% of the variation for males and 20% for females. This finding is consistent with the modest KR-20 values obtained for the test subscales. Items displaying undesirable psychometric characteristics common to the present study and the extant literature are identified.     

Impulsivity,sensation seeking and reproductive behaviour: A life history perspective

Impulsivity has often been invoked as a proximate driver of different life-history strategies. However, conceptualisations of “impulsivity” are inconsistent and ambiguities exist regarding which facets of impulsivity are actually involved in the canalisation of reproductive strategies. Two variables commonly used to represent impulsivity were examined in relation to reproductive behaviour. Results demonstrated that sensation seeking was significantly related to strategy-based behaviour, but impulsivity (defined as a failure to deliberate) was only weakly correlated. The effect of impulsivity disappeared when sensation seeking was controlled. Sex differences emerged for sensation seeking but not impulsivity. We conclude that “impulsivity” is not a unitary trait and that clearer distinctions should be made between facets of this construct.     

Avocational sensation seeking in high and low risk-taking occupations

This study investigated whether people engaged in high risk-taking occupations (involving placing themselves or others in jeopardy) would seek or prefer highly stimulating activities of a nonvocational nature more than people engaged in low risk-taking occupations. One hundred air traffic controllers (high risk-takers) were compared with 78 civil service employees and college students (low risk-takers). The high risk-taking group scored significantly higher than the low risk-taking group on all five dimensions of the Zuckerman Sensation Seeking Scale, indicating a higher need for sensation stimulation. These findings lend support to the proposition that risk-taking as a response style is related to occupational group membership.
