How Cross‐Linguistic Differences in the Grammaticalization of Future Time Reference Influence Intertemporal Choices

According to Chen's (2013) Linguistic Savings Hypothesis (LSH), our native language affects our economic behavior. We present three studies investigating how cross‐linguistic differences in the grammaticalization of future‐time reference (FTR) affect intertemporal choices. In a series of decision scenarios about finance and health issues, we let speakers of altogether five languages that represent FTR with increasing strength, that is, Chinese, German, Danish, Spanish, and English, choose between hypothetical sooner‐smaller and later‐larger reward options. While the LSH predicts a present‐bias that increases with FTR‐strength, our decision makers preferred later‐larger options and this future‐bias increased with FTR‐strength. In multiple regressions, the FTR‐strength effect persisted when controlled for socioeconomic and cultural differences. We discuss why our findings deviate from the LSH and ask in how far the FTR‐strength effect represents a habitual constitution of linguistic relativity or an instance of online decision framing.     

A threatening exchange: Gender and life history strategy predict perceptions and reasoning about sexual harassment

Sexual harassment is a serious societal issue, with extensive economic and psychological consequences, yet it is also an ill-defined construct fundamentally defined in terms of subjective perception. The current work was designed to examine the ways in which individual differences between people are systematically related to different perceptions of sexual harassment scenarios, as well as reasoning about those harassment situations. Participants (N = 460) read several possible harassment scenarios and rated how uncomfortable they would find them. They then also evaluated a quid pro quo sexual harassment situation in terms of their interpretation of it as a threat or a social exchange and completed a deductive reasoning task about the same situation. Females and individuals with slow life history strategies were more uncomfortable with potential harassment situations and were more likely to interpret the quid pro quo scenario as a threat. Further, interpreting the scenario as a threat was associated with poorer performance on the deductive logic task, compared to those who interpreted the scenario as a social exchange.     

Psychometric Evaluation of the Career Decision Scale With Iranian Undergraduate Students

The authors examined the reliability and construct validity of the Career Decision Scale (Osipow, Carney, & Barak, 1976 ) with 1,610 freshman and sophomore students from public universities from a southwestern state in Iran. A Cronbach's alpha of .80 provided strong support for the scale's reliability. Exploratory factor analysis results indicated a 2‐factor model (Diffusion and Internal/External Barriers) of the scale with Iranian students, which was confirmed by confirmatory factor analysis. Implications and recommendations for further research are discussed.     

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.     

Multi-stage mental process for economic choice in capuchins

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.     

Decision making and confidence given uncertain advice

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.     

Selfless giving

In four studies, we show that people who anticipate more personal change over time give more to others. We measure and manipulate participants’ beliefs in the persistence of the defining psychological features of a person (e.g., his or her beliefs, values, and life goals) and measure generosity, finding support for the hypothesis in three studies using incentive-compatible charitable donation decisions and one involving hypothetical choices about sharing with loved ones.     

The response dynamics of preferential choice

The ubiquity of psychological process models requires an increased degree of sophistication in the methods and metrics that we use to evaluate them. We contribute to this venture by capitalizing on recent work in cognitive science analyzing response dynamics, which shows that the bearing information processing dynamics have on intended action is also revealed in the motor system. This decidedly “embodied” view suggests that researchers are missing out on potential dependent variables with which to evaluate their models—those associated with the motor response that produces a choice. The current work develops a method for collecting and analyzing such data in the domain of decision making. We first validate this method using widely normed stimuli from the International Affective Picture System (Experiment 1), and demonstrate that curvature in response trajectories provides a metric of the competition between choice options. We next extend the method to risky decision making (Experiment 2) and develop predictions for three popular classes of process model. The data provided by response dynamics demonstrate that choices contrary to the maxim of risk seeking in losses and risk aversion in gains may be the product of at least one “online” preference reversal, and can thus begin to discriminate amongst the candidate models. Finally, we incorporate attentional data collected via eye-tracking (Experiment 3) to develop a formal computational model of joint information sampling and preference accumulation. In sum, we validate response dynamics for use in preferential choice tasks and demonstrate the unique conclusions afforded by response dynamics over and above traditional methods.     

Individual differences in willingness to become an organ donor: A decision tree approach to reasoned action

The promotion of organ donation requires a better understanding of the attributes associated with willingness to donate. This entails revealing complex interactions among personality attributes related to intentions and behaviors. In the present study, survey data from young adults (N = 367) were analyzed using decision tree algorithms to identify these interactions within the reasoned action framework. Within this structure, donation attitudes, intentions, and behaviors were examined in relation to individual differences such as conscientiousness, empathy, time orientation, religiosity, and interpersonal trust.     

Effects of approach and withdrawal motivation on interactive economic decisions

Although recent economic models of human decision making have recognised the role of emotion as an important biasing factor, the impact of incidental emotion on decisions has remained poorly explored. To address this question, we jointly explored the role of emotional valence (i.e., positive vs. negative) and motivational direction (i.e., approach vs. avoidance) on performance in a well-known economic task, the Ultimatum Game. Participants had to either accept or reject monetary offers from other players, offers that vary in their degree of unfairness. A main effect of motivational direction, but not valence, was observed, with withdrawal-based emotion (disgust and serenity) prompting more rejections relative to approach-based emotion (anger and amusement) and a neutral state. These results further confirm that subtle incidental moods can bias decision making, and suggest that motivational state may be a useful framework to study such decisions. Implications with regard to emotion, cognitive neuroscience, and clinical psychology are discussed.
