Autonomy facilitates repeated maximum force productions

Performer autonomy (or self-control) has consistently been shown to enhance motor learning, and it can also provide immediate benefits for motor performance. Autonomy is also a key variable in the OPTIMAL theory of motor learning (Wulf & Lewthwaite, 2016). It is assumed to contribute to enhanced expectancies and goal-action coupling, affecting performance effectiveness and efficiency. The purpose of the present study was to examine whether providing autonomy support by giving performers choices would enhance their ability to maintain maximum force levels. Participants were asked to repeatedly produce maximum forces using a hand dynamometer. After 2 initial trials with the dominant and non-dominant hand, stratified randomization was used to assign participants with the same average maximum force to one of two groups, choice or yoked control groups. Choice group participants were able to choose the order of hands (dominant, non-dominant) on the remaining trials (3 per hand). For control group participants, hand order was determined by choice-group counterparts. Maximum forces decreased significantly across trials in the control group, whereas choice group participants were able to maintain the maximum forces produced on the first trial. We interpret these findings as evidence that performer autonomy promotes movement efficiency. The results are in line with the view that autonomy facilitates the coupling of goals and actions (Wulf & Lewthwaite, 2016).     

The role of chance events in career decision making

Two studies are reported that investigate the role of chance events as influences in career decision making. In study one, the results of a large-scale survey of high-school and university students (N = 772) investigating influences on their career decision making are presented. Chance events were reported as influencing the career decisions of 69.1% of the sample. In the second study, the role of locus of control was found to be moderately associated with reporting chance events. More External control individuals tend to report more chance events than their Internal control counterparts. Implications for career choice theory and research are discussed.     

On self-referencing differences in judgment and choice

Compared to judgment, choice is argued to elicit more self-referent processing and thereby produce greater subsequent recall of evaluated information. This response mode effect is shown to be dependent upon sufficient visualization to overcome the use of heuristic processing during choice. When visualizing prior to the task, choice leads to increased thinking about personal consumption occasions relative to judgment, leading to enhanced recall of vivid (vs. non-vivid) attributes. This proposed interaction of task and visualization was found in two experiments that assessed incidental recall following a choice or judgment task. In experiment 1, participants recalled more vivid product attribute information after choosing between options than after rating each option separately, but only when instructed to visualize during evaluation. To eliminate a comparison-based explanation of this effect, a second experiment was conducted that presented only one option in each category. Participants who evaluated their intention to purchase the option (a judgment equivalent of choice) demonstrated greater recall of vivid product attribute information than did participants who rated their liking for the option, and this recall difference was again moderated by instructions to visualize.     

Social cognitive predictors of academic persistence and performance in engineering: Applicability across gender and race/ethnicity

We examined the utility of social cognitive variables in the longitudinal prediction of academic persistence and success of engineering students. The participants, 908 students enrolled in engineering majors at two state universities, completed measures of academic support, self-efficacy, outcome expectations, interests, satisfaction, positive affect, and intended persistence at the end of each of their first four semesters. In the current study, students' first and second semester responses were used to predict persistence and grade performance in engineering by the end of six semesters. Path analytic findings indicated that second-semester persistence intentions, satisfaction with the major, self-efficacy, and social support each produced direct paths to persistence. Objective ability (mathematics SAT scores), outcome expectations, and interests were linked to persistence indirectly via their relations to other variables in the model. In addition, self-efficacy and objective ability jointly predicted grade performance. Results were stable across gender and racial/ethnic groups. Implications for research and practice on academic adjustment in engineering are considered.     

Actions and outcomes: two aspects of agency

Agency can be construed as both the manner in which autonomous individuals embark on particular courses of action (or inaction), and the relationship between such agents and the outcomes of the courses of action on which they embark. A promising strategy for understanding both senses of agency consists in the combination of a modal logic of agency and branching time semantics. Such is the strategy behind stit theory, the theory of agentive action developed by Nuel Belnap and others. However, stit theoretic evaluations of the agentive relationship between agents and outcomes that are uncertain—due to either the presence of indeterminism, or the possible intervention of other agents—yield counterintuitive results. This paper develops a pair of alternative operators (the “act” operators) for modeling agency with respect to uncertain outcomes. Unlike the stit-theoretic model, the act-theoretic model of agency with respect to a particular state of affairs does not require that the state of affairs be realized in every possible history. If the state of affairs in fact obtains in the actual history, and its obtaining was dependent on the agent’s pursuing a particular course of action, then the agent is deemed agentive under act theory.     

The Indetermination of Reason and the Roleof the Will in Aquinas's Accountof Human Freedom

Thomas Aquinas argues that human choices are made by the will and reason working together. It is easy to misinterpret his argument and suppose that the reason alone works out what should be done while the will simply ratifies this. Instead Aquinas believes that in practical matters the reason is often undetermined since it arrives at many simultaneous conclusions. This is the often unacknowledged heart of Aquinas's account of freedom. All these simultaneous rational conclusions derive from the objective circumstances of the world; each one could give rise to a different rationally justified course of action; yet only one can be acted upon. The reason cannot decide between them. It is the will that accepts and affirms one of these conclusions and gives force to the reasonableness of one course of action. This is why a choice is always rational and personally willed – which is what makes it free. The indetermination of reason is what allows the future to be open-ended for the deliberating agent; it allows past and present to be interpreted in different ways, each of which has its own coherence and rationality. In this way Aquinas's account of human freedom avoids both an irrational voluntarism and a deterministic intellectualism     

An experimental analysis of satisficing in saving decisions

Uncertainty of one’s future is the essential problem of saving decisions. Unlike previous experimental studies, we capture this crucial uncertainty by a scenario-based satisficing approach. Decision makers first form aspirations for a few relevant scenarios, and then search for consumption plans guaranteeing these aspirations. Our aim is to investigate whether agents make satisficing choices and, if so, how satisficing relates to optimality. We find that satisficing allocations can be reached easily when aspirations are incentivized, although aspiration levels are rather far from what optimality suggests.
