Mediational effects of sensation seeking on the age and financial risk-taking relationship

The current study examined the potential mediating role of sensation seeking in the well-established negative relationship between age and financial risk-taking. A total of 299 participants, aged 17–90 years, allocated hypothetical money into mutual funds that varied in risk and completed a sensation seeking measure. Hierarchical multiple regressions revealed that the amount of variability age accounted for in risk-taking (4.1%; β = −.22) was significantly reduced when sensation seeking was controlled for (0.8%; β = −.12). A Sobel test revealed that sensation seeking fully mediated the aforementioned relationship. Results suggest sensation seeking’s role as a mediator in more physiologically arousing risk-taking contexts (e.g., surfing). Discussion recommends investigating potential biologically and cognitively-rooted mediators and moderators of the age and risk-taking relationship.     

Relationship between the sensation seeking scale and a biographical inventory designed to predict risk-taking behavior

One hundred and five students were administered both Zuckerman's Sensation Seeking Scale (SSS) and the Torrance-Ziller biographical inventory (BI) for measuring risk-taking tendencies. Correlations between the BI and selected subscales on the SSS were positive and significant. However, the proportion of explained variance does not suggest that the SSS and the BI are tapping the same dimension.     

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.     

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.     

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.     

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.     

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.     

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.     

Embedding sensation seeking within the big three

While Sensation Seeking is a construct which loads on both Extraversion (E) and Psychoticism (P), it is not clear whether Sensation Seeking can be reduced to E and P and whether all of its subfactors necessarily load on the same factor(s). We therefore decided to investigate the relationship among these. The 682 participants comprised a heterogeneous sample. They completed the SSS (Form V) and then the EPQ-R-S (short version of the revised EPQ). Factor analysis of the EPQ-R-S revealed simple structure, with 46 of the 48 items being correctly located on their respective factors. Analysis of the SSS also revealed simple structure, with 31 of the 40 items being correctly located on their respective factors. When the items from the EPQ-R-S and SSS were combined in one analysis, using a 4-factor constraint, we could identify these as follows: The first factor entailing items from 3 SSS scales (ES, Dis and BS) and 2 EPQ scales (L and P), could be referred to as Impulsive Unsocialized Sensation Seeking (P-ImpUSS). The second was identified as N; the third was identified as E; and the fourth as TAS. Thus it is P which loads on P-ImpUSS, with TAS being distinct from the latter.     

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.     

Sensation seeking and danger invulnerability: Paths to college student risk-taking

This study examines the roles of sensation seeking and invulnerability as predictors of health compromising behaviors in a multiethnic sample of 1690 emerging adult college students (mean age = 19.8, range 18–25 years) from nine US colleges and universities. Participants completed the Arnett Sensation Seeking Inventory and the Adolescent Invulnerability Scale; and reported how often they had participated in a set of health compromising risk behaviors (i.e., substance use, impaired driving, and sexual behaviors) in the 30 days prior to assessment. Sensation seeking and danger invulnerability scores were moderately correlated (r = .30). Findings from a series of multivariate Poisson regression analyses suggest that when considered simultaneously as predictors, sensation seeking appears to be a general risk factor associated with engagement in a variety of risk behaviors, whereas danger invulnerability is primarily a factor in those risk behaviors that are less common among peers (e.g., hard drug use, casual sex, and driving while intoxicated).     

Collegiate heavy drinking prospectively predicts change in sensation seeking and impulsivity

Recent models of alcohol use in youth and young adulthood have incorporated personality change and maturation as causal factors underlying variability in developmental changes in heavy drinking. Whereas these models assume that personality affects alcohol use, the current prospective study tested the converse relation. That is, we tested whether, after accounting for the effect of traits on drinking, collegiate heavy drinking in turn predicted individual differences in change in alcohol-related aspects of personality. We also examined whether affiliation with heavy-drinking peers better accounted for this relation. Following a cohort of recent high school graduates (N=1,434) through the college years, we found evidence for transactional relations between heavy drinking and changes in impulsivity and sensation seeking. Both traits predicted increases in heavy drinking, but more important, heavy drinking predicted increases in sensation seeking and impulsivity. In final models, social influences did not underlie the effect of heavy drinking on increases in sensation seeking and impulsivity. The results of this investigation suggest that collegiate heavy drinking may negatively and pervasively impact a wide range of behaviors because of its effect on personality change.     

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.     

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.     

A comparison of impulsivity and sensation seeking in pathological gamblers and skydivers

The aim of this study was to compare pathological gamblers and skydivers in relation to measures of impulsivity and sensation seeking. The Eysenck Impulsivity Scale - Narrow Impulsiveness Subscale and the Arnett Inventory of Sensation Seeking were administered to pathological gamblers (n = 29), skydivers (n = 93), and a control group (n = 43). A two-way multivariate analysis of variance was conducted to explore differences in impulsivity and sensation seeking between the groups and possible group by gender and group by age interaction effects. The significant effects were further investigated using follow-up univariate analysis of variance. The results showed significant main effects of Group, Gender and Age, and a significant Group by Gender interaction effect. The results showed no statistically significant differences in impulsivity between pathological gamblers and skydivers; however, both groups scored higher than the controls. The skydivers scored higher compared to the pathological gamblers and controls on both sensation seeking subscales. Pathological gamblers scored higher than the controls on the subscale Need for Stimulus Intensity, although lower than the controls on the subscale Need for Novelty. We conclude that skydivers and pathological gamblers do not seem to differ in terms of impulsivity, but that the two groups differ in terms of sensation seeking. Skydivers are hence characterized by more sensation seeking compared to pathological gamblers. Skydiving, as opposed to pathological gambling, is not considered a psychiatric disorder, and skydiving may represent a more non-pathological way to fulfill the need for stimulus intensity.     

Loving, liking, looking and sensation seeking in unmarried college couples

This study examined the relationships between sensation seeking or sensation seeking similarity and relationship satisfaction in college couples. Fifty-eight couples were tested with the Sensation Seeking Scale form V and the Loving and Liking Scales, and each couple was observed for eye gaze behavior. Eye gaze was found to be unrelated to the questionnaire measures of relationship involvement and a low but significant negative relationship was found between the female partner's love rating and mutual gaze and focus. As in previous research, couples' sensation seeking scores were significantly correlated, indicating tendencies toward assortative mating. However, only the women's relationship satisfaction scores were related to discrepancies in the couples' SSS scores. Individual sensation seeking scores correlated negatively with relationship satisfaction for both sexes. The latter effect was explained in terms of the high sensation seeker having a variety of interests outside of their primary relationships, and stronger tendencies for boredom and independence.     

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.     

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.
