Erroneous choice and foregone gains in hoarding gray jays (Perisoreus canadensis)

Under the conventional assumption that natural selection favors choice behavior that maximizes some fitness-related currency, a forager making repeated binary choices should consistently choose the more valuable option. Under the alternative assumption that natural selection favors choice behavior that minimizes costly errors, erroneous choice is not only expected but is expected to be common when the cost of errors is low. This cost depends on the potential rate of return: the higher this rate, the smaller the cost of choosing the less valuable option. When this rate is very high, a forager may err frequently and yet forego no appreciable fitness gain. Errors should thus be more common when interruptions to foraging are shorter. Our experimental results supported this prediction: gray jays chose the less valuable option more frequently when subjected to shorter interruptions (experimentally imposed delays to access to food rewards). This tendency is consistent with the idea that an adaptive decision-making process may routinely produce errors, not because errors are in some way adaptive but because their fitness cost is minimal, particularly when delays are short. From a proximate perspective, this tendency to commit errors more frequently following shorter delays may be due to constraints on the jays’ information-processing capacity. In general, choice behavior should be viewed as the joint byproduct of adaptive decision making and cognitive constraints. Received: 8 June 2000 / Accepted after revision: 21 October 2000     

When, what, and how much to reward in reinforcement learning-based models of cognition

Reinforcement learning approaches to cognitive modeling represent task acquisition as learning to choose the sequence of steps that accomplishes the task while maximizing a reward. However, an apparently unrecognized problem for modelers is choosing when, what, and how much to reward; that is, when (the moment: end of trial, subtask, or some other interval of task performance), what (the objective function: e.g., performance time or performance accuracy), and how much (the magnitude: with binary, categorical, or continuous values). In this article, we explore the problem space of these three parameters in the context of a task whose completion entails some combination of 36 state-action pairs, where all intermediate states (i.e., after the initial state and prior to the end state) represent progressive but partial completion of the task. Different choices produce profoundly different learning paths and outcomes, with the strongest effect for moment. Unfortunately, there is little discussion in the literature of the effect of such choices. This absence is disappointing, as the choice of when, what, and how much needs to be made by a modeler for every learning model.     

Spiritual Maturity and Wholeness – A Concept Whose Time Has Come

SUMMARY

Legal advocates, clergy and politicians have all been challenged by the concept of the separation of church and state since the first European set foot on the American continent. Two schools of thought have been developed for this unique problem in the United States. Roger Williams took the position that there needs to be a separation of church and state in order to keep the church pure from the politics and every day work of the state. Thomas Jefferson, who is often attributed with developing this concept, took the position that the need for this separation was to protect the state from the church. Both positions often get articulated as if they are one concept in the United States. However, they are very different. This debate has carried itself in the current millennium into the work of the Office of Faith-Based Initiatives as well as the legislation known as Charitable Choice.     

Refining the dual‐process theory of preference construction: A reply to Gawronski,Martin and Sloman,Stanovich, and Wegener and Chien

Our target article proposed a dual-system framework for understanding context and task effects in choice. In this summary, we address the major points made by each set of commentators and, building on their suggestions, define a more precise dual-system theory of preference construction. We also propose some avenues for future research on a broader dual-system approach to understanding choice.     

Sadness and consumption

Sadness influences consumption, leading individuals to pay more to acquire new goods and to eat more unhealthy food than they would otherwise. These undesirable consumption effects of sadness can occur without awareness, thus representing more than just conscious attempts at “retail therapy.” In an experiment with real food consumption, the present paper examines the hypothesis that sadness' impact on consumption could be attenuated if the choice context counteracted appraisals of helplessness and enhanced a sense of individual control. Results revealed that: (1) sadness elevates self-reports of helplessness in response to the emotion-inducing situation, (2) helplessness mediates the sadness–consumption effect, and (3) inducing a sense of control (via choice) attenuates sadness' effect.     

Personality,epistemology and psychotherapists' choice of theoretical model: a review and analysis

This article reviews a body of research, empirical and speculative, describing variables thought to determine a psychotherapist's choice of theoretical orientation. The review finds two types of variables (1) the influences of training, colleagues, supervisors, initial clinical experience and (2) the effects of personality traits and epistemological values, beliefs and philosophy. The weight of evidence from the reviewed studies of cognitive behavioural/behavioural and psychodynamic psychotherapists, and an analysis of the data, suggests that personality and epistemic traits are significantly involved in orientation choice. This has implications for training, practitioner and client outcome satisfaction, and understanding the poor communication that exists between these two major orientations.     

Applying social cognitive career theory to predict interests and choice goals in statistics among Spanish psychology students

This study investigated the usefulness of social cognitive career theory—SCCT (Lent, Brown, and Hackett, 1994) in predicting interests and goals relating to statistics among psychology students. The participants were 1036 Spanish students who completed measurements of statistics-related mastery experiences, self-efficacy, outcome expectations, interests and goals/intentions. Structural equation modeling (including multi-group analysis) was used to test the fit of the hypothesized models to the data. Results indicated support for SCCT as a way to predict students' interests in statistics and their intentions of engaging in academic or professional activities where statistics is used. Collectively, the predictors accounted for 50% of the variance in interests and for 77% of the variance in goals. Implications both for future research on SCCT and for intervention in statistics education are discussed.     

Role stressors and counterproductive work behavior: The role of negative affect and proactive personality

Based on the stressor‐emotion model, we propose that negative affect mediates the relationship between three role stressors (i.e., role ambiguity, role conflict, and role overload) and counterproductive work behavior (CWB), while proactive personality moderates the relationships between negative affect, role stressors, and CWB. We tested our hypotheses using data from 332 employees in Mainland China. We found that negative affect mediated the relationships between the three dimensions of role stressors and CWB. Role ambiguity was most strongly associated with CWB, followed by role conflict and then role overload. Proactive personality moderated the role ambiguity‐negative affect, role conflict‐negative affect, and negative affect‐CWB relationships, but not the relationship between role overload and negative affect.     

Choosing Across Cultures: The Effect of Choice Complexity on Treatment Outcomes

Prior research has revealed that having choice over treatments can improve their efficacy. However, it is currently unknown if the benefits of treatment choice hold for complex decisions and different cultures. The effects of differing numbers of treatment options were explored across two cultural contexts: United States and Japan. Participants were exposed to an uncomfortable stimulus and provided with up to 15 placebo treatment options they believed would reduce discomfort. There was a significant interaction such that participants from Japan benefited most from fewer treatment options (2 and 5) compared with more treatment options (10 and 15). Participants from the United States, however, showed either no change in discomfort or less discomfort as the number of choices increased. Additionally, participants from Japan reported less satisfaction with the decision process when they had more treatment options to choose from whereas U.S. participants reported similar, if not slightly higher, satisfaction with more treatment options. Further, a second study indicated that a positive experience with the decision process mediated the relationship between choice complexity and treatment efficacy for Japanese participants. These data demonstrate the importance of culture and choice complexity when discussing treatment choice and resulting outcomes in the medical context. Copyright © 2015 John Wiley & Sons, Ltd.
