The moderating role of attitude strength in selective exposure to information

Individuals prefer to receive information that is consistent with their attitudes. Three experiments examined whether attitude strength moderates this selective exposure effect. Experiments 1A and 1B found that participants preferred attitudinally consistent information but that this effect was more pronounced to the extent that the attitude was strongly held. Experiment 2 replicated these findings and ruled out an alternative interpretation that a general tendency to hold strong attitudes rather than issue-specific attitude strength moderates selective exposure. Discussion concerns the implications of these findings and the possibility that other variables moderate the selective exposure effect.     

Does Watching Smoking in Movies Promote Teenage Smoking?

ABSTRACT— Compared to adolescents with low exposure to smoking in movies, those with high exposure are about three times as likely to try smoking or become smokers. We have observed this effect in nationally representative samples using cross-sectional and longitudinal designs. This effect remains statistically significant after controlling for numerous other traditional risk factors, such as personality, parenting style, and sociodemographics. Indeed, the movie-smoking exposure effect on adolescent smoking initiation is greatest among those traditionally considered at lower risk for smoking, such as those low in sensation seeking and those whose parents do not smoke. In this article, we consider possible moderators and mediators of this important media effect as well as health-policy implications. The take-home message is that eliminating smoking in movies may prevent a substantial number of adolescents from smoking.     

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).     

Mothers’ and Fathers’ Reluctance to Seek Psychological Help for Their Children

We investigated the gap between parents’ willingness to seek help for their children and their willingness to refer other parents to help, and the relationship of this gap to gender. Two hundred and eleven parent couples with elementary-school children reported their willingness to seek help from professional and informal sources for a hypothetical problem with their child, and their willingness to refer a friend’s child with an identical problem to similar help. Attitudes toward help seeking and parental behaviors were also measured. Findings revealed that parents were more willing to refer a friend’s child to professional help than they were to seek such help for their own child, although no gap was found regarding informal help. No gender differences were found regarding willingness to seek help or to refer another, although gender was related to variables that predicted help seeking.     

特质焦虑与青少年冒险行为的关系：基于双系统模型的机制探讨

为了考察特质焦虑与青少年冒险行为的关系并基于双系统模型探究其中的影响机制,本研究采用特质焦虑问卷、简版自我控制量表、感觉寻求量表和青少年多领域冒险行为问卷对1720名12～18岁的青少年进行问卷调查,共回收有效数据1549份。结果发现：（1）特质焦虑能正向预测青少年的冒险行为,自我控制在特质焦虑与冒险行为间的关系中起中介作用;（2）感觉寻求调节了该中介过程的后半路径,即个体的感觉寻求水平越高,自我控制对冒险行为的预测作用越大。     

小鼠新颖寻求特质对酒精的运动激活效应的影响

新颖寻求(或感觉寻求)特质与许多成瘾药物的易感性密切相关。例如, 高、低新颖寻求动物对可卡因、苯丙胺和吗啡等成瘾药物的奖赏、运动激活、强化效应的反应存在差异。长期饮用酒精也容易成瘾, 但尚未发现关于新颖寻求特质影响酒精成瘾的报道。本实验采用药物成瘾研究中常用的自发活动模型, 考察了高、低新颖寻求动物在酒精急性处理、慢性处理和激发过程中的行为表现。实验过程中首先采用两种新颖寻求模型, 即新颖环境中自发活动模型和新颖客体偏爱模型, 将昆明小鼠分别区分为高、低自发活动组和高、低新颖客体偏爱组, 连续10天给予酒精(2g/kg/d, i.p.)或等量盐水处理, 戒断2天后所有小鼠接受酒精(2g/kg)激发。实验结果表明, 新颖环境低自发活动小鼠比新颖环境高自发活动小鼠对酒精急性、慢性处理导致的运动激活效应更敏感; 在酒精激发期前者的自发活动水平也高于后者。本实验结果说明新颖环境中自发活动特质影响动物对酒精导致的运动激活效应的反应。     

Psychological Distress and Help Seeking in Rural America

The implications of exposure to acute and chronic stressors, and seeking mental health care, for increased psychological distress are examined. Research on economic stress, psychological distress, and rural agrarian values each point to increasing variability within rural areas. Using data from a panel study of 1,487 adults, a model predicting changes in depressive symptoms was specified and tested. Results show effects by size of place for men but not for women. Men living in rural villages of under 2,500 or in small towns of 2,500 to 9,999 people had significantly greater increases in depressive symptoms than men living in the country or in larger towns or cities. Size of place was also related to level of stigma toward mental health care. Persons living in the most rural environments were more likely to hold stigmatized attitudes toward mental health care and these views were strongly predictive of willingness to seek care. The combination of increased risk and less willingness to seek assistance places men living in small towns and villages in particular jeopardy for continuing problems involving depressed mood.     

Risk aversion in information seeking

The information gain model argues that participants select alternatives with a larger expected value of information gain. The present study investigated risk aversion in information seeking to examine whether the expected value always determines information-seeking behaviour. For this investigation, we used a scale method selection task in which participants were required to select one of two scales for weighing coins in order to find an underweight coin. Two experiments showed that participants more frequently selected the alternative that provided information gain without risk, although its expected information gain was smaller. This finding indicates the presence of risk aversion in information seeking, suggesting that information-seeking behaviour is affected by risk associated with obtaining information gain.     

Ambiguity seeking in multi-attribute decisions: Effects of optimism and message framing

This paper investigates the influence of message framing and personality variables on preferences over ambiguity in the context of multi-attribute decision scenarios. Undergraduate subjects responded to scenarios in which one of two medical treatments was associated with ambiguous probabilities of treatment effects. Probabilities were either positively or negatively framed. Subjects indicated their degree of preference for one treatment over the other. Subjects' optimism, trait anxiety, health locus of control, need for cognitive structure, and current mood were measured. In two separate studies, subjects preferred ambiguity when probabilities were positively framed, and were neutral toward ambiguity when probabilities were negatively framed. Also, in both studies the preference for ambiguity in positively framed scenarios was greater for more optimistic subjects. The unexpected finding of ambiguity seeking may be associated with the use of different decision strategies in multi-attribute versus single-attribute decisions.     

Analogue drinking assessment: Sensation seeking and gender

This study assessed the relationship between sensation seeking measured as a trait variable and drinking behaviors observed unobtrusively in the laboratory. It was hypothesized that high-sensation-seeking subjects would consume more alcohol than low sensation seekers and experience greater enhancement of positive moods and body sensations associated with intoxication. Thirty female and 31 male subjects divided into high- and low-sensation-seeking subgroups participated in an ad libitum drinking situation with the manifest task of taste rating three types of vodka (actually 95% alcohol) or tonic. Dependent variables included beverage consumption, positive/negative mood states, body sensations, breath estimates of blood alcohol levels, and self-rated level of intoxication. All subjects reported feeling the effects of alcohol. Contrary to predictions, high-sensation-seeking subjects neither consumed more alcohol than their low-sensation-seeking counterparts nor drank more alcohol than tonic, Paradoxically, low-sensation-seeking women displayed significantly greater alcohol intake and intoxication than all other groups. Possible explanations for findings were considered as well as the necessity for multimethod assessments of both predictor (i.e., sensation seeking) and criterion (i.e., alcohol consumption) variables across time and situations.This research was supported by Grant Award AA04042-03 from the National Institute on Alcohol Abuse and Alcoholism to the first and third authors.
