为什么信息超载损害决策?基于有限认知资源的解释

信息超载是指需要处理的信息量大于信息加工的能力。信息超载会降低决策质量, 延长决策时间, 降低决策满意度, 引起慢性压力。信息超载损害决策的机制可以从有限的注意力资源和工作记忆资源来解释。在信息超载条件下, 一方面用于过滤和控制信息的注意力资源总量被快速消耗, 注意力资源的分配和利用受到无关信息的干扰, 信息得不到高效加工; 另一方面负责保持和加工信息的工作记忆在限定时间内不能充分加工海量信息, 进而损害决策绩效。未来可以运用眼动赋权法探索信息超载下的信息加工模式; 发展意识思维和无意识思维的动态耦合模型指导个体减轻信息超载; 探索运用智能代理和交互记忆系统缓解组织中的信息超载。     

Job demands and resources: Flourishing and job performance in South African universities of technology settings

We investigated the extent to which perceived job demands and resources influenced work-related flourishing and job performance among academic staff in South African universities of technology. Participants were 339 lecturers from three universities of technology (female = 53.8%; junior lecturers = 15.7%; mean age = 45 years, SD = 10 years; job tenure = 77.3% more than five years). Lecturers completed job demands, job resources, flourishing at work, and job performance measures. We utilised latent variable modelling to predict flourishing at work and job performance scores from job demands and resources scores. The results indicated job resources (specifically role clarity, advancement, and remuneration) to predict flourishing at work. Role clarity and flourishing at work predicted job performance. In line with job demands theory, the availability of resources was positively associated with flourishing at work and job performance of academic employees.     

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     

The effect of visual signals on spatial decision making

We examined the effect of an irrelevant visual transient on the decision where to look for a hidden object. Participants also performed a conventional ‘inhibition of return’ localization task. In Experiments 1 and 2 the two tasks were blocked and in Experiments 3 and 4 they were randomly interleaved. In every experiment there was a bias to select the cued location in the spatial decision task. This facilitory effect was greatest when the cue occurred at a strategically unfavored location and even occurred for participants who reported strategically selecting a non-cued location, indicating that the facilitory effect is automatic and independent of other strategic biases. Inhibition of return was observed only when the tasks were blocked and the localization task preceded the decision task. The findings suggests that spatial decisions engage different attentional control settings than those engaged when detecting visual transients; and that this attentional mode affects the processing of visual transients such that they do not inhibit the subsequent speeded detection of onset targets.     

The problem of delayed causation in a video game: Constant, varied, and filled delays

A first-person shooter video game was adapted for the study of causal decision making within dynamic environments. The video game included groups of three potential targets. Participants chose which of the three targets in each group was producing distal explosions. The actual source of the explosion effect varied in the delay between the firing of its weapon and the effect (from 0 to 2 s), whether these programed average delays were constant or varied from shot to shot, and whether the delays were unfilled or filled with an auditory event. In Experiment 1, participants’ choice accuracy was highest with shorter delays, but there was no effect of filling the delay and some beneficial effect of varying the delay. These results were re-examined in Experiment 2 but with participants experiencing the same average delay for seven subsequent decisions before the next average delay was introduced. In this experiment, men showed a strong and consistent benefit of filling a delay whereas women did not. Participants’ behavior is considered within the context of a model that assumes that choice behavior is driven by experienced contiguity for the target and foils.     

The interactive effects of role overload and resilience on family-work enrichment and associated outcomes

ABSTRACT

Using an interactionist perspective and conservation of resources (COR) theory, this study examined the interactive effects of resilience and role overload on family-work enrichment and the outcomes of surface acting, emotional exhaustion, and job satisfaction. The model was tested using a sample of 156 full time employees who completed surveys at two time periods. As expected, resilience was positively related to family-work enrichment and family-work enrichment was negatively related to surface acting and emotional exhaustion and positively related to job satisfaction demonstrating mediating effects for family-work enrichment. Role overload moderated the positive relationship between resilience and family-work enrichment such that the relationship was weaker when role overload was high indicating a boundary condition for the favorable effects of resilience. Finally, support was found for the conditional indirect effects of resilience on surface acting, emotional exhaustion, and job satisfaction through family-work enrichment such that the relationships were weaker when role overload was high.     

From Glossy to Greasy: The Impact of Learned Associations on Perceptions of Food Healthfulness

We demonstrate that consumers have learned that unhealthy snacks such as potato chips tend to be sold in glossy packages, whereas healthier snacks such as crackers tend to be sold in matte packages (in studies 1–3). As a result, consumers who see a snack food package with a glossy [matte] surface will infer lesser [greater] healthfulness of its contents (study 4), consume less [more] of it (study 5), and be more likely to choose a glossy [matte] package from an assortment of snack packages if motivated to engage in tasty [healthful] eating (study 6). Theoretical and managerial implications as well as future research opportunities are discussed.
