Reinforcement sensitivity theory at work: punishment sensitivity as a dispositional source of job-related stress

Gray's reinforcement sensitivity theory (RST) describes two important personality constructs; sensitivity to reward and sensitivity to punishment. In two studies, we examine whether these constructs can be considered dispositions to work stress. Results of Study 1 (N = 105 employees in different occupations) indicated that employees with strong punishment sensitivity reacted more strongly to work stressors than others. This idea was confirmed in a longitudinal design in Study 2. Reward sensitivity was unrelated to stress in both studies. Overall, results strongly support the idea that punishment sensitivity is a dispositional source of work stress. Results further confirm that RST and its derived personality measures can contribute to theorizing about personality–environment interactions in a highly relevant daily setting, namely the working environment.

Driving aggression in forensic and non‐forensic populations: Relationships to self‐reported levels of aggression,anger and impulsivity

A series of four questionnaires — the Buss‐Perry Aggression Questionnaire (AQ), the Barratt Impulsivity Scale (BIS‐11), the Driving Anger Scale (DAS) and a Driving Violence Inventory (DVI) — were administered to a sample of 473 British drivers consisting of undergraduates (N=185), members of the public (N=106) and offenders (N=182) serving sentences in closed prisons in England (violent=82, non‐violent=100). Offenders consistently rated acts of driving aggression as less severe compared with other drivers. Offender attributions of driving violence differed to other drivers in that they were equally likely to perceive obscene gesturing as high or low intensity responses; they also viewed assault as a high intensity response whereas members of the public rated it more severely. Trait levels of anger and aggression were the predictors of driving violence in all groups but previous aggressive behaviour was only a predictor for the offenders. Gender and age were found to be predictors of aggressive driving in non‐offenders. Even with the effects of age controlled, offenders (and violent offenders in particular) scored higher on measures of driving anger and aggression. These data suggest that offenders differ in their perceptions of aggressive behaviours experienced in everyday driving and as a consequence are more likely to commit acts that other drivers perceive as violent. As offenders are known to display similar perceptual biases in other domains, identified as precursors to their aggressive behaviour, it seems likely that experience effects (as reflected in the trait measures) underpin differences in driving aggression between offenders and non‐offenders.     

Psychological and sexual functioning among outpatient sexual offenders against children: A Minnesota Multiphasic Personality Inventory (MMPI) cluster analytic study

Multivariate clustering procedures were used to identify homogeneous subgroups of outpatient sex offenders against children (n=110)on the basis of the Minnesota Multiphasic Personality Inventory (MMPI). Results indicated a five-subgroup solution. Two within-normal-limits and two clinically elevated profile subgroups replicated subtypes found in previous cluster analytic studies of child sex offenders. The fifth subgroup appeared similar in MMPI profile pattern and elevation to a previously identified subtype of rapists. Discriminant analyses showed that subgroups differed along dimensions of cognitive disturbance and sexual functioning. Furthermore, levels of psychopathology corresponded with levels of sexual pathology. Results are discussed with reference to previous MMPI cluster analytic studies of sex offenders and theories of sexual aggression.Portions of this paper were presented at the meeting of the Midwestern Psychological Association, 1992, Chicago, Illinois.     

Are criminals better lie detectors? Investigating offenders' abilities in the context of deception detection

The present research examined lie detection abilities of a rarely investigated group, namely offenders. Results of the studies conducted thus far indicated a better performance of offenders compared to non‐offenders when discriminating between true and false messages. With two new studies, we aimed at replicating offenders' superior abilities in the context of deception detection. Results of Study 1 (N = 76 males), in contrast, revealed that offenders were significantly worse at accurately classifying true and false messages compared to non‐offenders (students). Results of Study 2 (N = 175 males) revealed that offenders' discrimination performance was not significantly different compared to non‐offenders (clinic staff). An internal meta‐analysis yielded no significant difference between offenders and non‐offenders, questioning the generalizability of previous findings.     

Reward versus punishment: Reinforcement sensitivity theory,young novice drivers’ perceived risk,and risky driving

One reason that young novice drivers remain statistically over-represented in road deaths is their rate of engagement in risky driving. Prominent contributing factors include driver’s age, sex, personality, risk perception, and their driving experience. This study applied reinforcement sensitivity theory (RST, specifically reward sensitivity and punishment sensitivity) to predict young novice drivers’ perceived risk and self-reported risky driving engagement, while accounting for potential influences of age, sex, and driving experience. Drivers (N = 643, 490 females, 17–25 years, M = 20.02, SD = 2.32) who held an Australian driver’s license (P1, P2, or Open) anonymously completed an online survey containing the Behaviour of Young Novice Drivers Scale, the Sensitivity to Punishment and Sensitivity to Reward Questionnaire, and a measure of perceived risk of driving-related behaviours. A path analytic model derived from RST showed that perceived risk had the strongest negative association with reported risky driving engagement, followed by reward sensitivity (positive association). Respondent’s age and reward sensitivity were associated with perceived risk. Age, reward sensitivity, and perceived risk were associated with reported engagement in risky driving behaviours. Driver sex only had direct paths with RST variables, and through reward sensitivity, indirect paths to perceived risk, and reported risky driving. Neither punishment sensitivity nor driving experience contributed significantly to the model. Implications and applications of the model, and the unique set of variables examined, are discussed in relation to road safety interventions and driver training.     

Juvenile Sex and Non‐Sex Offenders: A Comparison of Recidivism and Risk

Forty male juvenile sex offenders were compared with 133 male juvenile non‐sex offenders 2 years postrelease from residential treatment to assess recidivism and factors related to recidivism. Juvenile sex offenders had significantly lower recidivism rates than juvenile non‐sex offenders.     

Musical ability and non‐native speech‐sound processing are linked through sensitivity to pitch and spectral information

Is the observed link between musical ability and non‐native speech‐sound processing due to enhanced sensitivity to acoustic features underlying both musical and linguistic processing? To address this question, native English speakers (N = 118) discriminated Norwegian tonal contrasts and Norwegian vowels. Short tones differing in temporal, pitch, and spectral characteristics were used to measure sensitivity to the various acoustic features implicated in musical and speech processing. Musical ability was measured using Gordon's Advanced Measures of Musical Audiation. Results showed that sensitivity to specific acoustic features played a role in non‐native speech‐sound processing: Controlling for non‐verbal intelligence, prior foreign language‐learning experience, and sex, sensitivity to pitch and spectral information partially mediated the link between musical ability and discrimination of non‐native vowels and lexical tones. The findings suggest that while sensitivity to certain acoustic features partially mediates the relationship between musical ability and non‐native speech‐sound processing, complex tests of musical ability also tap into other shared mechanisms.     

The cheating and intention of a partner as determinants of evaluative decisions among juvenile offenders

Male juvenile offenders were asked to evaluate the work of an experimental partner (confederate) who completed a work task four times. The work partner cheated on two trials and did not cheat on two trials while working for a charity (one cheat and one noncheat trial) or for selfish gain (one cheat and one noncheat trial). It was found that subjects rated the work done on cheating trials lower than work done on noncheating trials. In addition, subjects shared less reward money on cheating trials relative to noncheating trials. However, the intentions of the confederate, defined as the reward recipient, failed to affect subjects' judgments. These results were described as supporting previous studies which have indicated that delinquents fail to take account of others' intentions when making moral judgments.     

Pathways in the offending process of sex offenders who target marginalised victims

Prior literature shows that although marginalised populations are at a high risk of severe violence and homicide, research has focused on their offenders as if they constituted a homogeneous group. On the basis of a sample of 213 sex offenders who targeted marginalised individuals (i.e., sex trade worker, homeless individual, and severe drug user), we investigate the different pathways that these offenders take both prior to and during the commission of their crimes. Results of 2‐step cluster analysis regarding the offender's development, criminal history, crime context, and modus operandi revealed 3 distinct pathways of the offending process. The coercive pathway was characterised by the amount of violence used against the victim. The explosive pathway was defined by offenders who were in a state of rage at the time of the offence. Finally, offenders in the situational pathway committed their crimes out of opportunity and used very little violence. Differences between pathways were investigated with regard to characteristics of the index offence.     

Reliability of heterosocial skills measurement with sex offenders

The heterosocial skills of 79 sex offenders were assessed using two self-report inventories, the Social Anxiety and Distress Scale (SAD) and the S-R Inventory of Anxiousness (SRI). In addition, staff members rated the offenders on modified versions of the SAD and the Heterosocial Skills Behavior Checklist for Males (HSB). Twenty-one offenders were also videotaped during a brief interaction with a female confederate. The tapes were rated using the HSB. All ratings and videotapings were conducted twice within a two-week period. The two self-report scales showed good test-retest reliability (r=.88) and correlatedr=.63 with each other. However, the SAD correlated significantly with the Crowne-Marlowe Social Desirability Scale and showed significant change from first to second administrations. The SRI showed less reactivity to social desirability and changed less over time. The staff ratings showed higher test-retest (r=.72–.76) than interrater (r=.36–.43) reliability. They correlatedr=–.56 with each other and did not show a significant relationship to the Crowne-Marlowe. However, both staff-ratings changed significantly from test to retest. Inspection of correlations between staff and self-report measures indicated that these instruments may be strongly affected by rater variance. Different measures completed by the same person correlated higher than the same measure completed by different persons. The HSB showed high levels of interrater agreement (90–100%) and split-half reliability (r=.95–.97). However, test-retest reliability was poor for the overall score and for the category measuring form of conversation. Categories measuring voice and affect were moderately reliable over time (r=.53–.74). However, the voice category scores changed substantially from first to second videotaping. On almost all measures used in this study, the sex offenders' scores were similar to those derived from normal populations. Only the category measuring affect on the HSB seemed to differentiate this group from normals.     

Development of Japanese version of the long‐term mating orientation scale (LTMO‐J)

The purpose of this study was to validate the 7‐item long‐term mating orientation scale (LTMO) as translated into Japanese. Two samples of Japanese adults (N = 2000; 50.0% male; Mage = 40.9 for the first survey; N = 300; 54.7% male; Mage = 42.4 for the second survey) completed a web‐based questionnaire, including the Japanese translation of the LTMO. The results showed that the psychometric properties of the Japanese LTMO scale were comparable to those of the original English version. The scale had adequate reliability based on Cronbach's α and McDonald's ω. Convergent validity was demonstrated by the correlation between the LTMO scores and related variables: human life history strategies, short‐term sociosexual orientation, attitude to infidelity, romantic attachment style, and so on. The translated scale provides a valid and reliable instrument in Japanese that measures human mating strategy.     

Social closeness of MZ and DZ twin parents towards nieces and nephews

Twins' marriages to non‐twins yield genetically and socially informative kinships. Monozygotic (MZ) twins' genetic identity makes them ‘genetic parents’ of their nieces/nephews, and their nieces/nephews their ‘genetic children’. The present study is the first to apply twin‐family models to study social relatedness. Analyses of twin families (MZ: N = 248; DZ: N = 75) tested evolutionary‐based concepts concerning social closeness, perceived similarity and caretaking. Hypotheses based on Hamilton's inclusive fitness theory were supported: MZ twin aunts/uncles expressed greater social closeness towards their nieces/nephews than DZ twin aunts/uncles; and female twins from same‐sex pairs expressed greater closeness towards their nieces/nephews than male twins from same‐sex pairs. This study underlines benefits of associations between behavioural‐genetic and evolutionary psychological theories, methods and interpretations. Copyright © 2007 John Wiley & Sons, Ltd.     

The translation and validation of the Mini‐K scale in Japanese

The purpose of this study was to validate the 20‐item Mini‐K scale, which is the short form of the Arizona Life History Battery, as translated into Japanese. Two samples of Japanese adults (N = 2000; 50.0% men; Mage = 40.9 for the first survey; N = 400; 50.0% men; Mage = 42.2 for the second survey) completed a web‐based questionnaire, including the Japanese translation of the Mini‐K. The results showed that the psychometric properties of the Japanese Mini‐K scale were comparable to those of the original English version. The scale had good reliability based on Cronbach's α and McDonald's ω. Convergent validity was demonstrated by the correlation between the Mini‐K scores and life history indicators. In addition, the Mini‐K score was related to both personality and psychosomatic health. The translated scale provides a valid and reliable instrument in Japanese that measures human life‐history strategy.     

An examination of the assumptions of specialization, mental disorder, and dangerousness in sex offenders

Sex offenders have been singled out for differential treatment by the legal and mental health systems. This article attempts to inform law reform efforts and criminal justice mental health policy by examining the assumptions underlying differential legal and mental health treatment of sex offenders. These assumptions include the theories that sex offenders are mentally disordered and in need of treatment, specialists in sex crimes, and more dangerous than other criminal offenders. Empirical findings demonstrate that sex offenders are not specialists in sex crimes and are not mentally disordered. Examination of past research suggests that sex offenders are not at more risk than other criminal offenders to commit future sex crimes. Implications of research findings for selective prosecution of sex crime cases, mental health policy, sex offender legislation, and predictions of future dangerousness are discussed. Proposals for future research needs and law reform are presented.     

Evaluating the Psychometric Properties of the Teamwork KSA Test

The Teamwork KSA Test has been a welcome addition to the practitioner's selection toolkit as well as a useful measure for teamwork researchers. We analyzed the psychometric properties of the Teamwork KSA Test and recognized correlates of the construct using three samples of working individuals recruited through a university (N = 241, N = 230, N = 332) and found slim evidence for a factor structure of the underlying constructs. Furthermore, classical reliability estimates did not meet traditional psychometric standards. Total TKSA scores predicted self‐ratings and instructor ratings of teamwork in two of the samples; effect sizes were small.     

The discriminative validity of a phallometric test for pedophilic interests among adolescent sex offenders against children

The authors examined the responses of adolescent sex offenders against children on a phallometric test of pedophilic interests. Participants were 40 adolescent sex offenders against children, 75 young adult sex offenders against children, and 39 young adult comparison participants. The responses of adolescents with female victims resembled those of comparison participants; adolescents with any male victims had larger relative responses to child stimuli than comparison participants. Young adult offenders, regardless of victim sex, had larger relative responses to child stimuli than comparison participants. Using a cut score of 0 (indicating equal or greater arousal to children than to adults), sensitivity was 42% for adolescents with any male victims, and specificity was 92% for the comparison participants. Results suggest phallometric testing can identify pedophilic interests among these adolescent sex offenders.     

Sex-role orientation and attachment styles of sex offenders

Given the increase of individuals who have a history of sexual offenses, there has been an increase in research on the etiology of sex-offending behavior. The present purpose was to evaluate the relationship between sex-role orientation and attachment styles of males who were sex offenders. Analysis yielded statistically significant differences between comparison (n = 22) and clinical groups (n = 21) in gender roles, with little sign of the androgynous gender type for sex offenders. The offender group showed significantly lower frequency of androgyny scores and significantly higher scores on feminine and undifferentiated orientations, supporting the theoretical view of sex offenders as being "cross-sex-typed." In addition, the sex offender group had a significantly higher mean score on anxious-avoidant relationship attachment. Based on the present findings, there appears to be a need to help sex offenders explore how their gender roles may relate to their sex-offending behavior and assist sex offenders in the development of adaptive relationships with reduced anxiety and ambivalence.     

Sex differences in impulsivity: a meta-analysis

Men are overrepresented in socially problematic behaviors, such as aggression and criminal behavior, which have been linked to impulsivity. Our review of impulsivity is organized around the tripartite theoretical distinction between reward hypersensitivity, punishment hyposensitivity, and inadequate effortful control. Drawing on evolutionary, criminological, developmental, and personality theories, we predicted that sex differences would be most pronounced in risky activities with men demonstrating greater sensation seeking, greater reward sensitivity, and lower punishment sensitivity. We predicted a small female advantage in effortful control. We analyzed 741 effect sizes from 277 studies, including psychometric and behavioral measures. Women were consistently more punishment sensitive (d = -0.33), but men did not show greater reward sensitivity (d = 0.01). Men showed significantly higher sensation seeking on questionnaire measures (d = 0.41) and on a behavioral risk-taking task (d = 0.36). Questionnaire measures of deficits in effortful control showed a very modest effect size in the male direction (d = 0.08). Sex differences were not found on delay discounting or executive function tasks. The results indicate a stronger sex difference in motivational rather than effortful or executive forms of behavior control. Specifically, they support evolutionary and biological theories of risk taking predicated on sex differences in punishment sensitivity. A clearer understanding of sex differences in impulsivity depends upon recognizing important distinctions between sensation seeking and impulsivity, between executive and effortful forms of control, and between impulsivity as a deficit and as a trait.     

Homophobia in physical education and sport: The role of physical/sporting identity and attributes,authoritarian aggression,and social dominance orientation

We examined levels of, and reasons for, anti‐gay and anti‐lesbian prejudice (homophobia) in pre‐service physical education (PE) and non‐physical education (non‐PE) university students. Participants (N = 409; 66% female; N = 199 pre‐service physical educators) completed questionnaires assessing anti‐gay and lesbian prejudice, authoritarianism, social dominance orientation (SDO), physical/athletic identity and self‐concept, and physical attributes. ANCOVAs revealed that PE students had higher levels of anti‐gay (p = .004) and lesbian prejudice than non‐PE students (p = .008), respectively. Males reported greater anti‐gay prejudice (p < .001), but not anti‐lesbian prejudice, than females. Authoritarian aggression was positively associated with greater anti‐gay (β = .49) and lesbian prejudice (β = .37) among male participants. Among females, higher authoritarian aggression and SDO was associated with greater anti‐gay (β = .34 and β = .25, respectively) and lesbian (β = .26 and β = .16, respectively) prejudice. The physical identity‐related constructs of athletic self‐concept (β = .?15) and perceived upper body strength (β = .39) were associated with anti‐gay attitudes among male participants. Physical attractiveness (β = ?.29) and upper body strength (β = .29) were also associated with male participants’ anti‐lesbian prejudice. Regression analyses showed that the differences between PE and non‐PE students in anti‐gay and lesbian prejudice were largely mediated by authoritarianism and SDO. The present study is the first to examine the relationship between investment in physical/sporting identity and attributes and anti‐gay and lesbian prejudice in PE/sport participants. In the present sample, anti‐gay and lesbian prejudice was greater in pre‐service PE students than non‐PE students, but these differences appear to be explained by differences in conservative ideological traits. Additionally, physical identity and athletic attributes based around masculine ideals also appear to contribute to this prejudice in males.     

Differential effects of social and non‐social reward on response inhibition in children and adolescents

An important issue in the field of clinical and developmental psychopathology is whether cognitive control processes, such as response inhibition, can be specifically enhanced by motivation. To determine whether non‐social (i.e. monetary) and social (i.e. positive facial expressions) rewards are able to differentially improve response inhibition accuracy in typically developing children and adolescents, an ‘incentive’ go/no‐go task was applied with reward contingencies for successful inhibition. In addition, the impact of children's personality traits (such as reward seeking and empathy) on monetary and social reward responsiveness was assessed in 65 boys, ages 8 to 12 years. All subjects were tested twice: At baseline, inhibitory control was assessed without reward, and then subjects were pseudorandomly assigned to one of four experimental conditions, including (1) social reward only, (2) monetary reward only, (3) mixed social and monetary reward, or (4) a retest condition without reward. Both social and non‐social reward significantly improved task performance, although larger effects were observed for monetary reward. The higher the children scored on reward seeking scales, the larger was their improvement in response inhibition, but only if monetary reward was used. In addition, there was a tendency for an association between empathic skills and benefits from social reward. These data suggest that social incentives do not have an equally strong reinforcing value as compared to financial incentives. However, different personality traits seem to determine to what extent a child profits from different types of reward. Clinical implications regarding probable hyposensitivity to social reward in subjects with autism and dysregulated reward‐seeking behaviour in children with attention‐deficit/hyperactivity disorder (ADHD) are discussed.
