Personality and responses to appetitive and aversive stimuli: the joint influence of behavioural approach and behavioural inhibition systems

Gray’s reinforcement sensitivity theory (RST) posits two separable neurological systems involved in the regulation of personality and behaviour. The behavioural approach and inhibition systems facilitate the expression of appetitive (impulsive-sensation seeking traits) and aversive motivation (anxiety traits), respectively. Inconsistent findings regarding associations between measures of personality and behavioural responses to appetitive and aversive stimuli has led to a modification of RST including the notion that, rather than separable as first hypothesised, the two systems jointly influence behaviour. The current study was designed to investigate this proposal with an additional focus on the role of reinforcement expectancies. Seventy-eight participants completed two questionnaire measures of BIS/BAS activity (EPQ-R, SPSRQ) and two behavioural measures (Q-TASK, Card Arranging Reward Responsivity Objective Task). Findings were in general consistent with the original separable systems approach, however they also showed that aversive responses were highest in high BAS/high BIS individuals, thus suggesting an interactive account of BIS/BAS processes. Further, stronger positive correlations between self-report BAS traits and behavioural reward responsiveness were found for participants who perceived the task as more rewarding than initially expected. Discussion focuses on the role of reward expectancies and on the issue regarding separable vs. joint BIS/BAS systems.

Reactivity to alcohol-related cues: relationship among cue type, motivational processes, and personality

This study examined the relationship between personality traits implicated in the drinking literature (i.e., sensation seeking and anxiety) and reactivity to 2 different alcohol cues. The opportunity to consume alcohol was manipulated, and differences in urge and affective reactivity were assessed. Gray’s (1987) model of impulsive sensation seeking and anxiety was adopted to investigate relationships between personality and responses to the appetitive (consumption) and aversive (no consumption, nonrewarding) alcohol cues in 40 regular social drinkers. The consumption cue produced increases in appetitive motivation and positive correlations with sensation-seeking traits. The no-consumption cue produced increases in aversive motivation and positive correlations with anxiety-related traits. It was concluded that Gray’s model of impulsive sensation seeking and anxiety may provide a useful framework for examining the personality correlates of cue reactivity to different cues.

Personality, behavioural and affective characteristics of hazardous drinkers

The aim of this study was to investigate the influence of appetitive and aversive motivation on hazardous drinking behaviour by drawing on Reinforcement Sensitivity Theory (RST). A between-groups design examined differences between hazardous drinkers and matched controls on self-report and behavioural appetitive and aversive motivation. The relationship between motivational processes and changes in affective states following behavioural task performance was also examined. Data from 27 hazardous drinkers (M = 21.88 years, SD = 3.29) and 27 gender and age matched controls (M = 21.85 years, SD = 4.08) were utilised. The Card Arranging Reward Responsivity Objective Test (CARROT) assessed behavioural appetitive motivation and the computerised Q-TASK provided an index of behavioural aversive motivation. Self-report appetitive and aversive motivation was measured using the Sensitivity to Punishment and Reward Questionnaire (SPSRQ). Brief scales tapping state positive and negative affect were also administered. Hazardous drinkers were significantly higher than controls on self-report but not behavioural measures of appetitive motivation. Results also indicated that hazardous drinkers reported significantly higher levels of negative affect. These data suggest that hazardous drinkers are characterised by high trait appetitive motivation and state negative affect. It was suggested that RST may provide a useful framework for understanding both the appetitive and aversive motivational processes involved in drinking behaviour.

An integration of attachment theory and reinforcement sensitivity theory

This thesis examined how relationship experiences shape people's sensitivity to detect threat and reward in romantic relationships and substance use scenarios. Findings indicated that anxious individuals experienced difficulty in distinguishing between threat and reward. In contrast, avoidant individuals were quick to detect threat either fleeing or confronting the problem aggressively.

Reinforcement sensitivity theory and coping behaviours in alcohol use

This research examined how individual differences in coping styles and drinking motives are associated with personality in the prediction of alcohol use.

Motivation for behavior change among sex offenders: a review of the literature

Motivation for behavior change is considered a crucial issue in the treatment of sex offenders. However, there has been no systematic investigation of this issue. The first aim of this review is to draw together the literature related to motivation for behavior change among sex offenders. The second aim is to highlight issues that need to be addressed to facilitate an empirical investigation of motivation for change among sex offenders. It is argued that a better understanding of motivation for change among sex offenders will contribute to enhancing the efficacy of treatment programs for these offenders.

The assessment of motivation for behaviour change among sex offenders against children: an investigation of the utility of the Stages of Change Questionnaire

A better understanding of motivation for behaviour change among sex offenders against children would improve treatment programmes designed to modify sexual offending behaviour. However, investigation of this issue is limited by lack of theoretically and empirically sound measures of motivation for behaviour change among sex offenders. This paper reports on two studies that were conducted to investigate the psychometric properties (validity, reliability, and social desirability) of the Stages of Change Questionnaire, adapted to measure motivation for behaviour change among sex offenders against children. In Study 1, the psychometric properties of the questionnaire were assessed for sex offenders against children (n=36) who were on a treatment waiting list. In Study 2, the psychometric properties of the questionnaire were assessed for sex offenders against children (n=47) at pre-treatment, mid-treatment, and post-treatment. Both studies supported the validity and reliability of the adapted Stages of Change Questionnaire, and the influence of social desirability upon responding was less than expected. The results of this investigation supported the potential utility of the Stages of Change Questionnaire as a measure of motivation for behaviour change for sex offenders against children.

Self-concept and motivation as predictors of actual consumer behaviour

The need to predict consumer behaviour outcomes is considered to be a very important issue for marketers. Isolated individual psychological constructs such as attitudes, motives, personality traits and learning styles have been used to identify their predictive capacity for actual consumer behaviour with varying degrees of success. This paper attempts to test
empirically the predictive power of two constructs, motivation and self-concept, regarding business consumer’s actions in a service context, using an Australian representative sample.

Does the motivation to help differ between generation X and Y?

This exploratory study examines the motivation for helping from the perspective of Generation X and Y. A study of 422 respondents was conducted to investigate their perception of helping based on intrinsic (social or community need) and extrinsic motivation (personal need). The findings suggested significant group differences. Although there was no significant main effect for motivation to help as a personal need (extrinsic motivation) across the generations, an examination of the social and community need (intrinsic motivation) indicated that generation X considered social and community need more important than Generation Y.

Government influence on intrinsic and extrinsic motivation in environmental social marketing

There is a need for more effective and efficient social behavioural change programs instigated by public sector environmental management organisations. The concepts of intrinsic motivation and extrinsic motivation have been shown to provide insights into the environmental behaviour of various groups. The aim of the paper is to investigate the relationship between Intrinsic Motivation, Extrinsic Motivation and Government influence. In particular this study examines the inter-relationship between intrinsic and extrinsic motivation in environmental management. A random sample of 566 land managers in South-eastern Australia was obtained. A structural equation model was used to develop a model which identities the relationship between intrinsic motivation, extrinsic motivation and government influence.

Aversive sexism and emotion regulation in a masculine organization

This study explores aversive sexism as an extension of Dovidio and Gaertner's (2004) recent notion of aversive racism. In this study, we investigate the presence of aversive sexism by examining relationships between emotional experience and emotion regulation in a masculine organization, an Australian Police Force ('APF').
