Framing alters risk-taking behavior on a modified Balloon Analogue Risk Task (BART) in a sex-specific manner

Framing uncertain scenarios to emphasize potential positive or negative elements influences decision making and behavior. The current experiment investigated sex differences in framing effects on risk-taking propensity in a modified version of the Balloon Analogue Risk Task (BART). Male and female undergraduates completed questionnaires on sensation seeking, impulsiveness, and risk and benefit perception prior to viewing one of three framing conditions for the BART: (1) positively-framed instructions emphasizing the ability to earn money if balloons were inflated to large size; (2) negatively framed instructions emphasizing the possibility that money could be lost if balloons were inflated to bursting; and (3) completely framed instructions noting both possible outcomes. Results revealed correlations between BART performance and impulsiveness for both sexes. Compared to positive and complete framing, negatively framed instructions decreased balloon inflation time in women but not men, indicating sex differences in response to treatments designed to alter risk-taking behavior.     

Task framing reduces emotion decoding negativity biases in social anxiety

Social anxiety is associated with difficulty in decoding emotional expressions. In this work, we present two experiments demonstrating that manipulating the apparent social relevance of an emotion‐identification task can reduce these difficulties. In Experiment 1, we find that social anxiety predicts an oversensitivity to anger expressions when participants are told they are completing a task that measures social skills. However, when the same task is framed as a measure of intellectual skills, this oversensitivity to anger is eliminated. Experiment 2 finds that social anxiety interferes with participants' ability to discriminate real from fake smiles when participants are told they are completing a test of social skills, but not when they are completing an ostensible measure of intellectual skills.     

Construct Validity of the Balloon Analogue Risk Task (BART): Relationship with MDMA Use by Inner-City Drug Users in Residential Treatment

In a program of research assessing the validity of the balloon analogue risk task (BART; C. W. Lejuez et al., 2002) as a measure of risk taking, the BART was administered to a sample of inner-city drug users in residential treatment (n = 76). Construct validity of the BART was evaluated by measuring risk-taking behavior and 3,4-methylenedioxymethamphetamine (MDMA) use while controlling for self-reported impulsivity, sensation seeking, polysubstance use, and demographic variables. Supporting the construct validity of the BART, while controlling for interrelated variables in the context of logistic regression analyses, (BART) risk-taking propensity accounted for significant incremental variance in differentiating MDMA users from non-users. BART scores, polysubstance use, and younger age were most associated with MDMA use, and together these variables were associated with 91% classification accuracy in predicting MDMA use.     

Risk Taking for Sexual Versus Monetary Outcomes using the Balloon Analogue Risk Task

The present study examined risk-taking behavior in relation to sexual and monetary outcomes using the Balloon Analogue Risk Task (BART). Adult men (n = 61) completed two modified BART tasks (one with monetary outcomes and one with sexual outcomes) and a battery of self-report measures concerning sexual and nonsexual constructs. Several findings are reported. First, risk-taking behavior concerning sexual outcomes can be evoked and quantified using the modified BART task reported here. Second, risk-taking for money was associated with latent factors associated with criminal behavior, drug use, and gambling. Third, risk taking for sexual outcomes was associated with the latent factors of sexual excitability and criminal behavior. Results suggest that stimulus-specific measures of risk taking are better associated with some outcomes. Study findings are discussed in terms of their relevance to laboratory research on the behavioral processes that underlie risky decision making.

     

A comparison of the effects of thought suppression, distraction and concentration

This study compared the effects of suppression, focused-distraction, and concentration on controlling unwanted distressing thoughts, and examined how anxiety levels were associated with the use of each thought-control technique. In the study, college students were told to suppress thoughts about a distressing story, to suppress the same thoughts by focusing on an alternative distraction task, to simply concentrate on that alternative task, or to think about anything without restrictions for 6 minutes. This initial period was followed by a “free-thinking” period to assess the delayed effect of thought-control techniques. The results indicated that focused-distraction and concentration led to fewer intrusions of target thoughts than suppression, and concentration in turn resulted in fewer target intrusions than focused-distraction during the initial period. Participants in the focused-distraction and concentration condition also tended to report lower anxiety during the initial period than those who were told to suppress thoughts.     

Facial action patterns, electromyography, and moods in response to an insoluble task as a function of sex and sex-role differences

College students of either androgynous or sex-typed orientation were randomly assigned to either an insoluble concept-formation task or a solvable one. Posttreatment scores were compared for measures of dysphoric mood (Multiple Affect Adjective List), electromyographic responses (corrugator and zygomatic), and discrete facial responses (Facial Action Coding System). In Study 1, 18 androgynous women were compared to 16 feminine women; in Study 2, 16 androgynous men were compared to 16 masculine men. The insoluble task was associated with more corrugator activity (frowning) than the solvable task in both studies. Feminine women displayed more corrugator responses across both tasks than androgynous women. However, masculine men did not differ from androgynous men in over-all corrugator response activity. Androgynous women smiled more than feminine women on the facial action coding measure. Men subjected to the insoluble task reported significantly more anxiety, depression, and hostility. Masculine men scored higher on anxiety during the insoluble task than androgynous men, while the latter scored somewhat higher on anxiety in the other condition.

Fear,excitement, and financial risk-taking

Can fear trigger risk-taking? In this paper, we assess whether fear can be reinterpreted as a state of excitement as a result of contextual cues and promote, rather than discourage, risk-taking. In a laboratory experiment, the participants' emotional states were induced (fear vs. control), followed by a purportedly unrelated financial task. The task was framed as either a stock market investment or an exciting casino game. Our results showed that incidental fear (vs. control) induced risk-averse behaviour when the task was framed as a stock investment decision. However, fear encouraged risk-taking when the very same task was framed as an exciting casino game. The impact of fear on risk-taking was partially mediated by the excitement felt during the financial task.     

Construct validity of the Balloon Analog Risk Task (BART): associations with psychopathy and impulsivity

To continue research assessing the validity of the Balloon Analog Risk Task (BART) as a measure of risk taking, the BART was administered to a nonforensic sample of individuals with varying levels of psychopathic characteristics. Construct validity of the BART was evaluated by measuring risk-taking behavior in relation to self-reported psychopathy, anxiety, psychophysiological data, and demographic variables. Supporting the construct validity of the BART, while controlling for variance accounted for by interrelated variables in the context of hierarchical regression analyses, higher self-reported psychopathy was significantly predictive of increased risk taking on the BART. Findings also revealed interesting gender differences in self-reported psychopathy and a trend for men to engage in riskier behavior. Limitations and research directions are presented.

Factors contributing to individual differences in facial expression categorisation

Individuals vary in perceptual accuracy when categorising facial expressions, yet it is unclear how these individual differences in non-clinical population are related to cognitive processing stages at facial information acquisition and interpretation. We tested 104 healthy adults in a facial expression categorisation task, and correlated their categorisation accuracy with face-viewing gaze allocation and personal traits assessed with Autism Quotient, anxiety inventory and Self-Monitoring Scale. The gaze allocation had limited but emotion-specific impact on categorising expressions. Specifically, longer gaze at the eyes and nose regions were coupled with more accurate categorisation of disgust and sad expressions, respectively. Regarding trait measurements, higher autistic score was coupled with better recognition of sad but worse recognition of anger expressions, and contributed to categorisation bias towards sad expressions; whereas higher anxiety level was associated with greater categorisation accuracy across all expressions and with increased tendency of gazing at the nose region. It seems that both anxiety and autistic-like traits were associated with individual variation in expression categorisation, but this association is not necessarily mediated by variation in gaze allocation at expression-specific local facial regions. The results suggest that both facial information acquisition and interpretation capabilities contribute to individual differences in expression categorisation within non-clinical populations.     

Negative emotionality influences the effects of emotion on time perception

In this study I used a temporal bisection task to test if greater overestimation of time due to negative emotion is moderated by individual differences in negative emotionality. The effects of fearful facial expressions on time perception were also examined. After a training phase, participants estimated the duration of facial expressions (anger, happiness, fearfulness) and a neutral-baseline facial expression. In accordance to the operation of an arousal-based process, the duration of angry expressions was consistently overestimated relative to other expressions and the baseline condition. In support of a role for individual differences in negative emotionality on time perception, temporal bias due to angry and fearful expressions was positively correlated to individual differences in self-reported negative emotionality. The results are discussed in relation both to the literature on attentional bias to facial expressions in anxiety and fearfulness and also, to the hypothesis that angry expressions evoke a fear-specific response.     

互动情境下个体对他人面部表情的加工受到他人社会地位的影响

前人研究表明他人的社会地位影响个体对其面部表情的加工,但是他人地位如何影响个体对其面部表情加工的神经机制并不清楚。本研究首先让被试完成时间估计任务,然后让评价者（高VS低地位）根据被试任务成绩给予面部表情（愉悦、中性和愤怒）反馈,同时记录被试加工评价者面部表情的ERP成分。脑电结果发现,在早期的P1阶段,当评价者给予愤怒和愉悦表情作为反馈评价刺激时,低地位评价者比高地位评价者诱发了更强的P1波幅;在N2加工阶段,只有当评价者给予愉悦表情作为反馈评价刺激时,高地位评价者比低地位评价者诱发的N2波幅更强;在后期P3加工阶段,只有当评价者给予愉悦表情作为反馈评价刺激时,低地位评价者比高地位评价者诱发了更强的P3波幅。当前研究结果说明评价者的地位不仅影响了个体对其面部表情加工的早期阶段,而且还影响了个体对其面部表情加工的后期阶段。     

Effects of 7.5% CO(2) inhalation on allocation of spatial attention to facial cues of emotional expression

Increased vigilance to threat-related stimuli is thought to be a core cognitive feature of anxiety. We sought to investigate the cognitive impact of experimentally induced anxiety, by means of a 7.5% CO(2) challenge, which acts as an unconditioned anxiogenic stimulus, on attentional bias for positive and negative facial cues of emotional expression in the dot-probe task. In two experiments we found robust physiological and subjective effects of the CO(2) inhalation consistent with the claim that the procedure reliably induces anxiety. Data from the dot-probe task demonstrated an attentional bias to emotional facial expressions compared with neutral faces regardless of valence (happy, angry, and fearful). These attentional effects, however, were entirely inconsistent in terms of their relationship with induced anxiety. We conclude that the previously reported poor reliability of this task is the most parsimonious explanation for our conflicting findings and that future research should develop a more reliable paradigm for measuring attentional bias in this field.

越老越风险规避吗？——年龄对冲动性预测决策行为的调节效应

年老化伴随着风险承担倾向的改变,而决策行为受冲动性的影响是否受到年龄的调节尚不清楚。研究采用两种不同类型的决策任务以及Barratt冲动性量表,考察老年人风险承担在自我报告和决策行为上的改变。结果显示老年人在剑桥博弈任务中更加风险寻求而在模拟充气球任务中更加风险规避。同时冲动性可以显著预测模拟充气球的行为,且该预测受到年龄的调节。研究结果提示,老年人并不是单一的更加风险规避或者风险寻求,而是与任务特异性相关。同时,冲动性可以较好的预测年轻人的决策行为,而对老年人的决策行为没有预测作用。     

The relationship between blushing propensity, social anxiety and facial blood flow during embarrassment

To investigate blushing in relation to blushing propensity scores and core elements of social anxiety, facial blood flow was monitored in 86 normal volunteers during an embarrassing task (singing a children's song). Increases in facial blood flow were greater in women than men, as were scores on the Blushing Propensity and Fear of Negative Evaluation scales. In addition, high scores on the Blushing Propensity and Social Interaction Anxiety scales were associated with large increases in facial blood flow during singing. However, this appeared to be due primarily to social anxiety because the association between blushing propensity scores and changes in facial blood flow disappeared when social interaction anxiety scores were taken into account. These findings suggest that people generally base their beliefs about blushing on cues other than changes in facial blood flow. Social anxiety may augment increases in facial blood flow during embarrassment, independently of expected or perceived blushing.     

White lie-telling in children for politeness purposes

Prosocial lie-telling behavior in children between 3 and 11 years of age was examined using an undesirable gift paradigm. In the first condition, children received an undesirable gift and were questioned by the gift-giver about whether they liked the gift. In the second condition, children were also given an undesirable gift but received parental encouragement to tell a white lie prior to being questioned by the gift-giver. In the third condition, the child's parent received an undesirable gift and the child was encouraged to lie on behalf of their parent. In all conditions, the majority of children told a white lie and this tendency increased with age. Coding of children's facial expressions using Ekman and Friesen's (1978) Facial Action Coding System revealed significant but small differences between lie-tellers and control children in terms of both positive and negative facial expressions. Detailed parental instruction facilitated children's display of appropriate verbal and nonverbal expressive behaviors when they received an undesirable gift.     

Probing the attentional control theory in social anxiety: An emotional saccade task

Volitional attentional control has been found to rely on prefrontal neuronal circuits. According to the attentional control theory of anxiety, impairment in the volitional control of attention is a prominent feature in anxiety disorders. The present study investigated this assumption in socially anxious individuals using an emotional saccade task with facial expressions (happy, angry, fearful, sad, neutral). The gaze behavior of participants was recorded during the emotional saccade task, in which participants performed either pro- or antisaccades in response to peripherally presented facial expressions. The results show that socially anxious persons have difficulties in inhibiting themselves to reflexively attend to facial expressions: They made more erratic prosaccades to all facial expressions when an antisaccade was required. Thus, these findings indicate impaired attentional control in social anxiety. Overall, the present study shows a deficit of socially anxious individuals in attentional control—for example, in inhibiting the reflexive orienting to neutral as well as to emotional facial expressions. This result may be due to a dysfunction in the prefrontal areas being involved in attentional control.
