Factors influencing adolescents' decisions to engage in risk-taking behavior

Few studies have assessed adolescent risk-taking from a decision-making perspective while also looking at sensation-seeking and locus of control. In this study, 171 older adolescents completed a risk-taking inventory to measure risk involvement. Sensation-seeking and locus of control, as well as perceived benefits and costs, were assessed to determine their effects on risk-taking. Results showed that perceived risks affected risk-taking more significantly than did perceived benefits. Higher sensation-seeking tendencies were affiliated with more risk-taking. Locus of control was not related to risk-taking.     

The application of reinforcement and participant modeling procedures in the treatment of snake-phobic behavior

In Experiment I, one group of snake phobic Ss was reinforced (with tokens) for approaching a harmless snake. A second group received token reinforcement on a non-contingent basis, in the same setting, with a third group serving as non-treated controls. Although slight improvement was noted for all three groups, the groups did not differ significantly with respect to an increase in approach behavior or a reduction in subjective fear rating. A fourth group of snake phobic Ss was reinforced with money for approaching the snake, but showed no more improvement than the other three groups. In Experiment II. Ss who had participated in Experiment I were assigned to a participant modeling (P-M) group, in which they observed a fearless model interact with a snake and were subsequently guided through similar interactions with the snake, or to a non-treated control group. The P-M Ss showed a very marked decrement in snake phobic behavior (which generalized to a non-treatment snake) following the 40-min treatment, in contrast to control Ss who showed virtually no change.     

The development, validation, and application of a video-based technique for measuring an everyday risk-taking behavior: drivers' speed choice

Drivers' choice of speed is an important aspect of everyday risk-taking behavior because it has been shown to be one of the most important predictors of road accident involvement. This research developed, validated, and applied a measure of drivers' speed choice that combined a high degree of experimental control with external and ecological validity. In Study 1, a video-simulation measure of drivers' speed choice was developed and found to relate specifically to speed-related accident involvement, implying a degree of external validity. In Study 2, the measure was used to investigate the effect of auditory feedback on drivers' speed choice. It was found that increasing the level of internal car noise decreased drivers' preferred speeds. Further analyses indicated that this was likely due to perceptual effects on speed estimation. Results are discussed in terms of road safety and the ability of video-based measures to facilitate experimental control over tasks involving complex ecological stimuli.     

Autobiographical memory specificity and affect regulation: an experimental approach

This study investigated J. M. G. Williams's (1996) affect-regulation hypothesis that level of specificity of autobiographical memory (AM) is used to minimize negative affect. It was found that a negative event leads to more reports of subjective stress in high- as compared with low-specific participants. Also, afterward, high-specific participants rated their unprompted memories for the event as more unpleasant. The results indicate that, relative to high specificity, being less specific in the retrieval of AMs is associated with less affective impact of a negative event. Results are discussed within the affect-regulation model. It is suggested that future research take a more functional perspective on AM specificity.     

Familiarity, group exposure, and risk-taking behavior in gambling

This research studied the effect of familiarity and individual versus group participation on risk-taking behavior in gambling (American roulette). Thirty-eight subjects (21 men and 17 women) were randomly selected and assigned to two experimental groups that gambled either individually or in groups. Results revealed that players bet more heavily as they became more familiar with the game, whether playing alone or in groups.     

Alexithymia, verbal intellectual deficit, and neurological dysfunction in relation to risk-taking behavior

This study explored relationships between alexithymia (measured through the Toronto Alexithymia Scale), probable neurological dysfunction (Stroop Color Word Test), and “Verbal” and “Abstraction” IQ scores (Hartford-Shipley Institute for Living Scale) in relation to risk-taking behavior. Subjects were “anti-social” risk-takers (criminal offenders undergoing court-related residential drug treatment), “adventurous” risktakers (college students who regularly engage in such sports as rock-climbing and spelunking), or “normals” (college students who were neither adventurous risk-takers nor criminal offenders). Principal findings reveal that clinically relevant alexithymia is observed among risk-takers of either anti-social or adventurous variety less frequently, but among “normals” more frequently, than chance would predict; that the “verbal deficit pattern” in intellectual functioning is observed more frequently among adventurous risk-takers, less frequently among “normals,” and no more frequently among anti-social risk-takers than chance would predict; and that probable neurological dysfunction is observed more frequently among anti-social risk-takers but less frequently among adventurous risk-takers or “normals” than chance would predict. Results support only in part the Pallone-Hennessy (1999) conceptual model of the genesis and correlates of risk-taking in respect of anti-social, but not in respect of adventurous risk-takers. This study was supported by grants from the Henry Rutgers Scholars Program, Rutgers College, and the Fund for Correctional Psychology, Center of Alcohol Studies.

Domain specificity and mental chronometry in empirical aesthetics

This article is a commentary on ‘Ten years of a model of aesthetic appreciation and aesthetic judgments: The aesthetic episode – developments and challenges in empirical aesthetics’ (Leder & Nadal, 2014, this issue). It focuses on domain specificity and mental chronometry in empirical aesthetics.     

睡眠质量对冒险行为影响的证据及解析

睡眠质量影响个体冒险行为已得到许多研究的验证和支持。睡眠缺失既影响大脑前额叶功能的完整性, 也影响杏仁核、纹状体等脑区的激活, 从而降低了个体对危险的知觉和对损失的敏感, 导致冒险意愿和冒险行为增加。已往相关研究多以成人群体为研究对象, 且忽略了个体特质与所处社会环境在睡眠质量与冒险行为关系中的交互影响。由于青少年期睡眠不足和高冒险行为普遍存在, 未来研究应对青少年睡眠质量与冒险行为的关系及其中的影响作用机制, 尤其是神经机制给予更多关注。     

Domain generality and domain specificity in aesthetic appreciation

Aesthetic appreciation is looked at with respect to domain generality and domain specificity. Within the classic cognitive paradigm, modality- and domain-specific receptive processes are explored. These are then complemented with central processing structures. These reveal domain-specific as well as domain-general processing. Extending the classic cognitive science approach, the role of emotion in aesthetic appreciation is also explored. While domain-specific models of aesthetic appreciation are clearly called for, there are also numerous domain-general subprocesses and structures.     

Training public-speaking behavior: an experimental analysis and social validation

The effect of an instructional package on public-speaking behaviors was analyzed in two experiments. The instructional package was designed to teach public-speaking trainees to look at the audience, make gestures, and perform a number of speaking behaviors. The results of Experiment I, with a university student serving as the trainee, showed that the percentage of each category of public-speaking target behavior increased only after the instructional package was introduced for that category. The results of Experiment 2, with three low-income paraprofessional staff members of a neighborhood service center serving as trainees, showed that the percentage of target behaviors increased after the instructional package was introduced for the respective trainee. Audience ratings of public-speaking performance were correlated with direct observations of target responses. All trainees showed marked improvements in audience ratings from pretraining to posttraining. This study demonstrated an effective procedure for training public-speaking behaviors.     

Domain specificity in conceptual development: neuropsychological evidence from autism.

To understand some aspects of conceptual development it is necessary to take cognitive architecture into account. For this purpose, the study of normal development is often not sufficient. Fortunately, one can also study neurodevelopmental disorders. For example, autistic children have severe difficulties developing certain kinds of concepts but not others. We find that whereas autistic children perform very poorly on tests of the concept, believes, they are at or near ceiling on comparable tasks that test understanding of pictorial representation. A similar pattern was found in a second study which looked at understanding of a false map or diagram: normal 4-year-olds showed a marked advantage in understanding a false belief over a false map, while the autistic subjects performed better on the map. These findings suggest that the concept, believes, develops as a domain-specific notion that is not equatable with "having a picture (map or diagram) in the head." This result supports the existence of a specialized cognitive mechanism, which subserves the development of folk psychological notions, and which is dissociably damaged in autism. We extend these ideas to outline a new model of the development of false belief performance.     

Feedback in behavior modification: an experimental analysis in two phobic cases

Two illustrations of single-case research are described in which an isolated therapeutic variable was sequentially introduced, withdrawn, and reintroduced while changes in a clinically relevant behavior were measured. A claustrophobic patient and a knife-phobic patient received graduated practice in facing their phobic stimuli; length of time the claustrophobic patient stayed in a small dark room per trial, and length of time the knife-phobic patient kept knife exposed per trial were measured. In both experiments, when feedback of these time scores was withdrawn, ongoing progress was retarded. Reinstatement of feedback led to renewed improvement. In Experiment 2, adding and removing contingent verbal praise against a constant background of precise feedback did not significantly alter rate of progress.     

Longitudinal measurement invariance of psychosocial measures in physical activity research: an application to adolescent data

The current study served as a practical and substantive guide to establishing longitudinal measurement invariance of psychosocial measures commonly used in adolescent physical activity (PA) research. Psychosocial data on an initial sample of 878 adolescents (ages 11–15) recruited through primary care providers were provided at baseline, 6, 12, and 24 months. The target measures included family support, peer support, decisional balance (pros, cons), self‐efficacy, and behavioral strategies. Five of the six psychosocial measures exhibited strict longitudinal measurement invariance, with the sixth measure (self‐efficacy) exhibiting strong longitudinal measurement invariance. These findings support the equivalence of these measures across time, and provide the foundation to substantively interpret group differences and associations involving these measures and PA.     

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.     

Impulsiveness and risk-taking behavior: comparison of high-school and college students using the Barratt Impulsiveness Scale

The present study was undertaken in an attempt to determine the relationship of impulsiveness to risk-taking behaviors such as aggression, drug use, drunk driving and not wearing seatbelts among highschool and college students. The results of the study clearly demonstrate that high impulsives are involved in risk-taking behavior at a higher rate than low impulsive subjects. These findings suggest that high impulsive adolescents and young adults are at considerable risk of personal injury and present a potential source of injury to others. It is suggested that self-report questionnaires of impulsiveness might prove useful in the early identification of these high risk individuals. Once identified these individuals could be targeted for intensive educational interventions specifically designed to deal with their inability to delay gratification and general lack of impulse control.     

The impact of school connectedness on violent behavior, transport risk-taking behavior, and associated injuries in adolescence

Adolescents engage in many risk-taking behaviors that have the potential to lead to injury. The school environment has a significant role in shaping adolescent behavior, and this study aimed to provide additional information about the benefits associated with connectedness to school. Early adolescents aged 13 to 15 years (N = 509, 49% boys) were surveyed about school connectedness, engagement in transport and violence risk-taking, and injury experiences. Significant relations were found between school connectedness and reduced engagement in both transport and violence risk-taking, as well as fewer associated injuries. This study has implications for the area of risk-taking and injury prevention, as it suggests the potential for reducing adolescents' injury through school based interventions targeting school connectedness.
