Altering the Shape of Punishment Distributions Affects Decision Making in a Modified Iowa Gambling Task 下载免费PDF全文
Corrine J. Seeley Joshua G. A. Cashaback Carlyle T. Smith Richard J. Beninger 《决策行为杂志》2014,27(2):170-178
Neuroeconomics research has shown that preference for gambling is altered by the statistical moments (mean, variance, and skew) of reward and punishment distributions. Although it has been shown that altered means can affect feedback‐based decision making tasks, little is known if the variance and skew will have an effect on these tasks. To investigate, we systematically controlled the variance (high, medium, and low) and skew (negative, zero, and positive) of the punishment distributions in a modified version of the Iowa Gambling Task. The Iowa Gambling Task has been used extensively in both academic and clinical domains to understand decision making and diagnose decision making impairments. Our results show that decision making can be altered by an interaction of variance and skew. We found a significant decrease over trials in choices from the decks with high variance and asymmetrically skewed punishments and from the decks with low variance and zero skew punishments. These results indicate that punishment distribution shape alone can change human perception of what is optimal (i.e., mean expected outcome) and may help explain what guides our day‐to‐day decisions.

Three studies examined narcissism and behavioral decision making. Decision‐making tasks included the Iowa Gambling Task (IGT; Studies 1–3), Balloon Analogue Risk Task (Studies 1–3), Columbia Card Task (CCT; Studies 2 and 3), and Game of Dice Task (Study 3). To tease apart the contributions of grandiose narcissism (i.e., narcissism found in the general population), pathological narcissism, and narcissistic traits (i.e., grandiosity, entitlement, and exploitativeness) in decision making, we assessed grandiose narcissism in Studies 1 (n = 380) and 2 (n = 244), pathological narcissism in Study 2, and the narcissistic traits in Study 3 (n = 312). Grandiose and pathological narcissism failed to predict decision making regardless of whether or not decision making included immediate feedback. In Study 3, the narcissistic trait of grandiosity (i.e., having an inflated sense of self‐importance) was associated with greater risk taking on the CCT‐hot (i.e., provided immediate feedback), and entitlement was associated with greater risk taking on the IGT. Measurement and applied implications are discussed. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

Decision reversals often imply improved decisions. Yet, people show a strong resistance against changing their minds. These are well‐established findings, which suggest that changed decisions carry a subjective cost, perhaps by being more strongly regretted. Three studies were conducted to explore participants' regret when making reversible decisions and to test the hypothesis that changing one's mind will increase post‐outcome regret. The first two studies employed the Ultimatum game and the Trust game. The third study used a variant of the Monty Hall problem. All games were conducted by individual participants playing interactively against a computer. The outcomes were designed to capture a common characteristic of real‐life decisions: they varied from rather negative to fairly positive, and for every outcome, it was possible to imagine both more and less profitable outcomes. In all experiments, those who changed their minds reported much stronger post‐outcome regret than those who did not change, even if the final outcomes were equally good (Experiments 2 and 3) or better (Experiment 1).This finding was not because of individual differences with respect to gender, tendency to regret, or tendency to maximize. Previous studies have found that those who change from a correct to wrong option regret more than those who select a wrong option directly. This study indicates that this finding is a special case of a more general phenomenon: changing one's mind seems to come with a cost, even when one ends up with favorable outcomes.

The Role of Character Strengths and Importance of Family on Mexican American College Students' Career Decision Self‐Efficacy 下载免费PDF全文
Javier Cavazos Vela Gregory Scott Sparrow James F. Whittenberg Basilio Rodriguez 《Journal of Employment Counseling》2018,55(1):16-26
This study examined how character strengths and the importance of family influenced Mexican American college students' (N = 129) career decision self‐efficacy. Findings from a multiple regression analysis indicated that psychological grit and curiosity were significant predictors of career decision self‐efficacy. The authors discuss the importance of these findings and provide recommendations for future research. 相似文献

It has been shown in previous work [Action figures and men. Sex Roles 53, 877–885] that male participants who handled extremely muscular action figures had lower body esteem than those who did not handle action figures or a Ken doll. However, the internal mechanisms that dictated this effect are unclear. Therefore, the current study extended this previous work by having male participants handle action figures of varying muscularity and completing a lexical decision task with target words that consisted of both positive and negative body words and feeling words in order to determine if males would be primed to think negatively about their bodies and self or if positive thoughts about their bodies and self would be interfered with. The results show that those participants who handled the extremely muscular action figures responded significantly more slowly to feeling positive words (e.g., content, confident) and marginally more slowly to body positive words (e.g., muscle, bicep) than those who did not handle any action figures. Overall, this suggests that the interference of positive words, not the priming of negative words, is the internal mechanism that produces the decreased body image satisfaction after exposure to muscular stimuli. Implications and future research are discussed. 相似文献

We studied economic choice behavior in capuchin monkeys by offering them to choose between two different foods available in variable amounts. When monkeys selected between familiar foods, their choice patterns were well-described in terms of relative value of the two foods. A leading view in economics and biology is that such behavior results from stimulus-response associations acquired through experience. According to this view, values are not psychologically real; they can only be defined a posteriori. One prediction of this associative model is that animals faced for the first time with a new pair of foods learn to choose between them gradually. We tested this prediction. Surprisingly, we find that monkeys choose as effectively between new pairs of foods as they choose between familiar pairs of foods. We therefore, propose a cognitive model in which economic choice results from a two-stage mental process of value-assignment and decision-making. In a follow-up experiment, we find that the relative value assigned to three foods in sessions in which we tested them against each other combine according to transitivity. 相似文献

We study human decision making in a simple forced-choice task that manipulates the frequency and accuracy of available information. Empirically, we find that people make decisions consistent with the advice provided, but that their subjective confidence in their decisions shows 2 interesting properties. First, people's confidence does not depend solely on the accuracy of the advice. Rather, confidence seems to be influenced by both the frequency and accuracy of the advice. Second, people are less confident in their guessed decisions when they have to make relatively more of them. Theoretically, we develop and evaluate a type of sequential sampling process model—known as a self-regulating accumulator—that accounts for both decision making and confidence. The model captures the regularities in people's behavior with interpretable parameter values, and we show its ability to fit the data is not due to excessive model complexity. Using the model, we draw conclusions about some properties of human reasoning under uncertainty. 相似文献

"Chasing ones losses" is a key symptom among pathological gamblers (PGs). This study focuses on quantitative differences in episodic chasing (i.e., sequences of disadvantageous decisions within a single gambling session) between PGs and non-pathological gamblers (NPGs). We compared 61 PGs and 39 NPGs on the Iowa Gambling Task (IGT) and the Zuckerman Sensation Seeking Scale (SSS). The PGs showed significantly more chasing and had significantly poorer decision-making strategies than NPGs, particularly among males (F = 4.52, p < 0.05). Random players were significantly less sensation seeking than advantageous and disadvantageous (i.e., chasing) players, but there was no interaction with group or gender. The results suggest that quantifiable within-session gambling behavior holds important implications for detecting underlying vulnerabilities to gambling pathology. 相似文献

Optimism as modifier of escalation of commitment 总被引:1,自引:0,他引:1
Juliusson A 《Scandinavian journal of psychology》2006,47(5):345-348
To study whether optimism-pessimism modifies escalation of commitment, 52 undergraduates were told that they had made an unsuccessful investment, then they chose to continue or discontinue this investment. Optimism about future returns was induced in one group by varying the probability of a successful outcome from an initial low to medium, pessimism was induced in another group by varying this probability from an initial high to medium. Supporting the assumption of the manipulation, the results showed that optimistic participants preferred to continue investments whereas pessimistic participants preferred not to. As predicted, when the sunk cost increased, optimism led to escalation of commitment, whereas pessimism led to de-escalation of commitment. These effects were strengthened when probability of a successful outcome was ambiguous. 相似文献
