Influencing choice without awareness

Forcing occurs when a magician influences the audience’s decisions without their awareness. To investigate the mechanisms behind this effect, we examined several stimulus and personality predictors. In Study 1, a magician flipped through a deck of playing cards while participants were asked to choose one. Although the magician could influence the choice almost every time (98%), relatively few (9%) noticed this influence. In Study 2, participants observed rapid series of cards on a computer, with one target card shown longer than the rest. We expected people would tend to choose this card without noticing that it was shown longest. Both stimulus and personality factors predicted the choice of card, depending on whether the influence was noticed. These results show that combining real-world and laboratory research can be a powerful way to study magic and can provide new methods to study the feeling of free will.     

Incidental emotions associated with uncertainty appraisals impair decisions in the Iowa Gambling Task

With the Appraisal Tendency Framework, it has been established that (un)certainty appraisals associated with incidental emotions trigger the kind of information processing to cope with situation. We tested the impact of (un)certainty-associated emotions on a sequential task, the Iowa Gambling Task. In this task, intuitive processing is necessary to lead participants to rely on emotional cues arising from previous decisions and to making advantageous decisions. We predicted that certainty-associated emotions would engage participants in intuitive processing, whereas uncertainty-associated emotions would engage them in deliberative processing and lead them to make disadvantageous decisions. As expected, we observed in two distinct experiments, that participants induced to feel uncertainty (fear, sadness) were found to decide less advantageously than participants induced to feel certainty (anger, happiness, disgust).     

In‐group and role identity influences on the initiation and maintenance of students' voluntary attendance at peer study sessions for statistics

Background. Although class attendance is linked to academic performance, questions remain about what determines students' decisions to attend or miss class. Aims. In addition to the constructs of a common decision‐making model, the theory of planned behaviour, the present study examined the influence of student role identity and university student (in‐group) identification for predicting both the initiation and maintenance of students' attendance at voluntary peer‐assisted study sessions in a statistics subject. Sample. University students enrolled in a statistics subject were invited to complete a questionnaire at two time points across the academic semester. A total of 79 university students completed questionnaires at the first data collection point, with 46 students completing the questionnaire at the second data collection point. Method. Twice during the semester, students' attitudes, subjective norm, perceived behavioural control, student role identity, in‐group identification, and intention to attend study sessions were assessed via on‐line questionnaires. Objective measures of class attendance records for each half‐semester (or ‘term’) were obtained. Results. Across both terms, students' attitudes predicted their attendance intentions, with intentions predicting class attendance. Earlier in the semester, in addition to perceived behavioural control, both student role identity and in‐group identification predicted students' attendance intentions, with only role identity influencing intentions later in the semester. Conclusions. These findings highlight the possible chronology that different identity influences have in determining students' initial and maintained attendance at voluntary sessions designed to facilitate their learning.     

Lebanese adolescents’ expectations about social inclusion of peers in intergroup contexts

This study examined the role of group norms, group identity, age, contact, and stereotypes on youths’ decisions to include a peer in an intergroup context portraying Lebanese and American adolescents. Lebanese participants (N = 275), ages 12 and 16 years, were surveyed about expectations for inclusion of an out-group target with similar interests or an in-group target with different interests into their own Lebanese group or another American group. Findings indicated participants focused on shared interests, rather than national identity, when making inclusion decisions for either group and group norms mattered. Older participants expected American peers to be less inclusive towards an out-group peer. Direct contact predicted inclusivity of out-group American peers into one’s own Lebanese group, and indirect media-based contact predicted expectations for inclusivity into an American out-group. Findings have implications for interventions aimed at improving cross-national friendships which, in turn, have the potential to reduce prejudicial attitudes.     

Thinking of Others: Feminist Identification and the Perception of Others’ Beliefs

Previous research has shown that most women in the United States support feminist goals but do not label themselves as feminists. Concern over other people’s opinions of feminists may predict rejection of the feminist label. In the present study we predicted that feminists would be more likely than non-feminists to believe that other people view feminists favorably. One hundred seventy-one female participants completed the Berryman-Fink Semantic Differential Scale twice, once to indicate how they view feminists and again to indicate how they believe others view feminists. Contrary to our hypothesis, all women, regardless of feminist identification, believed that others view feminists negatively and as more likely to be homosexual than heterosexual. Relationships between participants’ own views of feminists and their perceptions of others’ views of feminists were explored. Transformative experiences that may lead a feminist to ignore their perception of society’s views are discussed.     

How partner‐satisfying decisions benefit relationships: An experience sampling study

Sometimes, individuals must choose between acting in a way that satisfies their own desire or acting in a way that satisfies their partner's desire. What are the consequences of choosing one over the other for individuals' well‐being and relationship? Using experience sampling data (934 reports by 106 participants) that assessed daily decision conflicts in relationships, we examined consequences of partner‐satisfying decisions. A higher proportion of partner‐satisfying decisions predicted more perceived needs fulfillment and marginally higher perceived relationship quality over the course of a week. Additionally, immediately after the partner‐satisfying decision, participants reported feeling closer to their partner, and reported more positive and less negative affect, even when controlling for the quality of the relationship.     

Introspective reports of reaction times in dual-tasks reflect experienced difficulty rather than timing of cognitive processes

Reports of introspective reaction times (iRTs) have been used to investigate conscious awareness during dual-task situations. Previous studies showed that dual-task costs in RTs (the psychological refractory period, PRP, effect) are not reflected in participants’ introspective reports. This finding has been attributed to conscious awareness of Task 2 being delayed while Task 1 is centrally processed. Here, we test this Temporal model and compare it to an alternative that assumes participants base their iRTs on experienced difficulty. We collected iRTs and difficulty estimates after each trial of a PRP paradigm in which the perceptual difficulty of either Task 2 (Experiment 1) or Task 1 (Experiment 2) was manipulated. Our results largely support the difficulty-based account, suggesting that in a dual-task situation, iRTs do not reflect timing of cognitive processes but are strongly influenced by the experience of difficulty.     

Pain and athletes: Contact sport participation and performance in pain

ObjectivesThis study examined the effect of cold pressor pain on performance in high-contact athletes, low-contact athletes and non-athletes.DesignA three-group between-subjects experimental design was used.MethodSeventy-one participants completed a motor task and a cognitive task of different complexity (easy or hard) both in pain and not in pain. The motor task involved participants throwing a tennis ball at numbered targets in the correct order. In the cognitive task, participants were required to check off the numbers one to twenty-five in the correct order from a grid of randomly ordered numbers. Task difficulty was increased by adding dummy targets (motor task) or extra numbers (cognitive task).ResultsCold pressor pain was rated as less intense by high-contact athletes during both tasks compared to low-contact athletes and non-athletes. High-contact athletes’ performance was not hampered by pain on the motor task, whereas it was in low-contact athletes and non-athletes. However, pain did not hamper performance for any group during the cognitive task. Low-contact and non-athletes did not differ from each other in their pain reports or the degree to which their performance was hampered by pain in either task.ConclusionsThis study provides evidence that adaptation to pain through participation in high-contact sports can enhance both pain tolerance generally and motor performance specifically under increases in pain. The mechanisms behind these differences warrant further exploration.     

Does the feedback from previous trials influence current decisions? A study on the role of feedback processing in making decisions under explicit risk conditions

Decision situations frequently provide information about the amount of gains and losses and winning probabilities. In decisions under these conditions, also called risk conditions, both the use of feedback and executive functions have been shown to influence the decision‐making process, as revealed in different patient populations. However, the influence of offering feedback in tasks examining decisions under risk conditions has not been investigated experimentally, so far. This was the aim of the present study. For this purpose, a sample of healthy individuals was examined with the Game of Dice Task, a decision‐making task that explicitly provides the rules for gains and losses and in which participants receive feedback after each trial. In addition, a modified version of this task was performed, in which the feedback after each trial and all associated feedback components were removed. Results indicate that participants had a lower performance in the modified Dice Task without feedback. They selected the disadvantageous alternatives more frequently, when they did not receive feedback following their choices. Task performance in either version was correlated with executive functioning. Conclusion: In decisions under risk conditions, both executive functions as well as the use of feedback following previous trials are important components for optimal performance. Results have implications for the interpretation of deficient decision making in patients with neuropsychological impairments as both disturbances in categorization and other cognitive processes as well as emotional dysfunctions can compromise decision making in risky situations.     

Age-related variance in decisions under ambiguity is explained by changes in reasoning,executive functions,and decision-making under risk

Previous literature has explained older individuals’ disadvantageous decision-making under ambiguity in the Iowa Gambling Task (IGT) by reduced emotional warning signals preceding decisions. We argue that age-related reductions in IGT performance may also be explained by reductions in certain cognitive abilities (reasoning, executive functions). In 210 participants (18–86 years), we found that the age-related variance on IGT performance occurred only in the last 60 trials. The effect was mediated by cognitive abilities and their relation with decision-making performance under risk with explicit rules (Game of Dice Task). Thus, reductions in cognitive functions in older age may be associated with both a reduced ability to gain explicit insight into the rules of the ambiguous decision situation and with failure to choose the less risky options consequently after the rules have been understood explicitly. Previous literature may have underestimated the relevance of cognitive functions for age-related decline in decision-making performance under ambiguity.     

The Influence of Positive Affect on the Decision Rule in Risk Situations: Focus on Outcome (and Especially Avoidance of Loss) Rather Than Probability

Two experiments examined the influence of positive affect on probability estimation and choice. Participants in whom positive affect had been induced, as well as no-manipulation controls, were asked to make both numerical evaluations of verbal probabilities in three-outcome gambles and actual betting decisions about similar gambles. Results from Experiment 1 showed the phenomenon labeledcautious optimism:Positive affect participants significantly overestimated the probabilities associated with phrases for winning relative to their estimates of probability of losing for the same phrases (optimism), while participants in a control condition did not; yet, in actual gambling situations, affect condition participants were much less likely to gamble than were controls when a real loss was possible (caution). Results of the betting task from Experiment 2 further indicated that affect participants used a betting-decision rule that was different from that of controls: They bet less than controls in gambles where potential losses were large, even though probability of loss was small, and they bet more than controls in gambles where the amount of the potential loss was small, even though the probability of loss was moderate or large. These findings suggest that positive affect can promote an overt shift from a decision rule focusing primarily on probabilities to one focusing on utilities or outcome values, especially for losses. Taken together, the results are compatible with an interpretation of the influence of positive affect in terms of an elaboration of positive cognitive material, and purposive behavior in decisions, rather than in terms of mere response bias.     

The influence of perceived parental responsiveness on athletes’ goal accomplishment,trait cognitive sport anxiety,and thriving: A semi-longitudinal study

The purpose of this study was to examine temporally distal influence at a three-month interval of perceived parental responsiveness on athletes’ goal accomplishment, trait cognitive sport anxiety, and thriving. Young players (154 males, 51 females, M = 12.50 years, SD = 0.65) involved in rugby, basketball, and handball participated in the study. Initially, participants set three goals to accomplish over the next three months and completed questionnaires assessing their perceptions of their parents’ responsiveness, perceived self-efficacy, and self-esteem. Three months later, participants completed questionnaires assessing their goal accomplishment, worry about sport performance, and thriving. The results showed that athletes’ perceptions of their mother’s/father’s responsiveness, mediated by perceived athletes’ self-efficacy to accomplish their goals, influenced their goal accomplishment and trait cognitive sport anxiety three months later. The results also showed that athletes’ perceptions of their mother’s/father’s responsiveness, mediated by athletes’ self-esteem, influenced athletes’ thriving and trait cognitive sport anxiety three months later. Overall, the present study uniquely contributes to the understanding of parent-athlete relationships by showing that athletes’ perceptions of their mother’s and father’s responsiveness influence certain distal outcomes three months later (i.e., goal accomplishment, sports anxiety, and thriving) while mediated by self-efficacy and self-esteem.     

Compensation method affects risk-taking in the Balloon Analogue Risk Task

Different participant compensation methods may have discrepant effects on decision-making in behavioral measures of risk-taking. Participants in clinical samples tend to receive session-based payment (often in conjunction with decision-based payment), whereas participants in student samples generally receive decision-based payment or no payment at all. This study examined the effect of different methods of participant payment on a behavioral measure of individual differences in risk-taking. Participants completed the Balloon Analogue Risk Task (BART) as well as questionnaire measures of sensation-seeking and impulsivity. Participants who received session-based payment engaged in significantly greater risk-taking in the BART compared to those who were paid based on their decisions and those who were not paid at all (i.e., those who were only compensated with course credit). These effects were not influenced by age, gender, sensation-seeking or impulsivity. These findings provide evidence that different compensation methods significantly influence participants’ risk-taking propensity as measured by the BART.

The turban effect: The influence of Muslim headgear and induced affect on aggressive responses in the shooter bias paradigm

Does Islamic appearance increase aggressive tendencies, and what role does affect play in such responses? In a computer game, participants made rapid decisions to shoot at armed people, some of whom wore Islamic head dress. We predicted and found a significant bias for participants to shoot more at Muslim targets. We also predicted and found that positive mood selectively increased aggressive tendencies towards Muslims, consistent with affect-cognition theories that predict a more top-down, stereotypical processing style in positive mood. In contrast, induced anger increased the propensity to shoot at all targets. The relevance of these results for our understanding of real-life negative reactions towards Muslims is discussed, and the influence of affective states on rapid aggressive responses is considered.     

Decision Making Characteristics and Decision Styles Predict Adolescents’ Career Choice Satisfaction

Choosing one’s future career represents one of the most important decisions individuals face during their development. In the present study, Croatian college students recollected the process of choosing their future professional paths at the end of high school, and evaluated the outcome of this process. Specifically, students described how they chose between different career options, typically different college majors, available to them at that time. They specified the number and main characteristics of considered alternatives, the underlying motivation and timing of committing to a particular option, and reported how satisfied they were with the made choices. Next, the present study explored the influence of several identified decision making characteristics on participants’ immediate and delayed satisfaction with the chosen option. Additionally, the influence of several decision styles on individuals’ satisfaction was investigated. The obtained results indicate that, among decision making features, decision certainty represented the only significant predictor of participants’ immediate satisfaction with the made decision. The appeal of the preferred option and the number of considered options were revealed as additional significant predictors of delayed satisfaction with the chosen alternative. With regard to decision styles, regret and a distinct commitment factor predicted participants’ satisfaction with the made choice.     

Disclosure Pattern and Follow-Up After the Molecular Diagnosis of BRCA/CHEK2 Mutations

Five to 10 % of all breast cancer cases are due to mutations of high penetrance susceptibility genes, especially BRCA1 and BRCA2. In families with known BRCA mutations, disclosure of genetic test results could induce relatives to undergo genetic testing themselves and adopt cancer risk management strategies, if necessary. This study examines disclosure patterns of individuals tested for mutations in the BRCA1, BRCA2 and CHEK2 genes to first-degree relatives with emphasis on a possible gender difference. It also assesses which management strategy is preferred by mutation-positive women in Belgium and the influence of psychological characteristics on communication and choice of management strategy. Ninety-nine adults from BRCA/CHEK2 families, selected from the Centre of Medical Genetics of Antwerp, were included in the study. They were provided with medical and psychological questionnaires, the latter being the Self-Assessment Questionnaire, which is the Dutch version of the Spielberger State-Trait Anxiety Inventory and the Dutch version of the Coping Inventory for Stressful Situations (CISS-NL). The survey focused on disclosure, coping and management strategies with special attention on possible gender differences. The influence of socio-demographic and medical data on disclosure and cancer risk management as well as the influence of psychological features were examined by means of various statistical analyses. Ninety-nine patients were included, of whom 25 (25 %) were male. Eighty-seven percent of the participants informed all of their adult first-degree relatives about their mutation status without any gender discrimination. Seventy-eight percent of highly-educated participants informed all of their adult first-degree relatives, compared to 98 % of less formally-educated participants (p?=?0.006). The majority of mutation-positive women preferred prophylactic surgery to surveillance. Psychological differences appeared to have little influence on disclosure patterns and management strategies. The gender difference seems to be less pronounced than previously assumed. A striking observation, however, is the fact that significantly more participants who were less formally-educated informed all of their adult first-degree relatives, compared to participants who were highly-educated. In our study population, most female mutation carriers opted for prophylactic surgery. Since the study population is small, further studies are needed to enhance the generalizability of these results.     

Dispositional happiness and affective forecasting: General or specific effect?

Recent findings suggest that dispositional traits can influence personal affective forecasting. In this study, we investigated the relationship between dispositional happiness and affective prediction about academic performance among undergraduate students. Participants were asked to predict their emotional reactions on a 7-point Likert scale in regard to an important exam’s result two months prior obtaining their results. All the participants were contacted by SMS (Short Text Message) 8 h after the results were available and were requested to rate their actual emotional feelings on the same scale. According to their scores on the subjective happiness scale, participants were assigned into ‘happy’ and ‘unhappy’ groups. Results show no emotional prediction differences between the two groups for extreme results (i.e. good and bad results). In contrast, happy participants predicted less negative emotional feelings than unhappy ones for moderate results. No differences appear for the emotional feelings assessed the day they received their exam’s scores. These findings support the idea that dispositional happiness is related to emotional prediction and, more particularly, indicate that happiness induces more positive feelings concerning moderate future events, but not for extreme ones. This study suggests that happiness induces a positive view about emotional coping for future intermediate accomplishments only and not a positive view of the future in general.     

时间定价对亲社会行为的影响

时间定价就是将金钱价格赋予时间之上,用金钱来衡量时间的价值。已有研究表明,时间定价激活时间经济价值最大化的心理定势,使个体更看重时间的经济回报,花更少的时间帮助他人。但是,时间定价对亲社会行为的影响可能并不仅仅局限于时间利他。本研究通过三个实验,除了考察时间定价对时间利他的影响外,还进一步探讨时间定价对金钱利他的影响。结果显示,时间定价不仅影响个体的时间利他行为,也削弱了金钱利他行为。这表明,时间定价所激活的经济效用心理定势不仅仅局限于时间这一种资源的效用。
