Simple Threshold Rules Solve Explore/Exploit Trade-offs in a Resource Accumulation Search Task

How, and how well, do people switch between exploration and exploitation to search for and accumulate resources? We study the decision processes underlying such exploration/exploitation trade-offs using a novel card selection task that captures the common situation of searching among multiple resources (e.g., jobs) that can be exploited without depleting. With experience, participants learn to switch appropriately between exploration and exploitation and approach optimal performance. We model participants' behavior on this task with random, threshold, and sampling strategies, and find that a linear decreasing threshold rule best fits participants' results. Further evidence that participants use decreasing threshold-based strategies comes from reaction time differences between exploration and exploitation; however, participants themselves report non-decreasing thresholds. Decreasing threshold strategies that “front-load” exploration and switch quickly to exploitation are particularly effective in resource accumulation tasks, in contrast to optimal stopping problems like the Secretary Problem requiring longer exploration.     

Illusory trust: Kanizsa shapes incidentally increase trust and willingness to invest

Previous research has shown that the completion of basic perceptual processes is intrinsically pleasant. In the absence of diagnostic and objective cues to trustworthiness, nondiagnostic factors such as positive affect can incidentally lead to reported and behavioral trust. On the basis of these two premises, it was tested whether positive affect from the completion of perceptual processes has implications for the formation of trust in first-time business-consumer interactions. We tested this hypothesis in four experiments, using the famous Kanizsa illusion as an exemplary perceptual process that has been shown to trigger positive affect. We found that participants trusted companies who featured a Kanizsa shape as their logo more than companies with closely matched logos that did not allow for the completion of a basic perceptual process. This was evident on self-reported (Experiment 1) as well as behavioral (Experiments 2–4) measures of trust. This effect even persisted under incentivized conditions (Experiment 4) and was partially mediated by the intrinsic pleasantness of perception (Experiment 3). These findings for the first time demonstrate that positive affect is not the only consequence of perception, but rather has further trickle-down consequences for social judgments and economic decision making. Perceptual illusions seem to elicit illusory trust. Therefore, these novel findings bear important implications not only for both logo design and marketing but also for consumer decision making.

The Significance of Political and Economic Change in Two Generations of Slovaks and Hungarians

Two generations of Slovaks and of Hungarians responded to a short questionnaire sampling their opinions about recent political and economic changes in their respective countries. The younger generation were aged 18–23 and the older generation 40–45. In general, Slovaks expressed a higher degree of freedom of choice compared to Hungarians in various areas of their lives. Hungarians reported themselves to be more interested in politics at all levels (national, European and international) than their Slovak counterparts. These and other significant effects (relating to generational differences and differences in levels of education) are discussed in relation to recent changes in the political economies of the two countries.

Navigating Social Class Roles in Community Research

This paper describes the first author's attempt to collect data in a homeless shelter without attending to her role in the social class hierarchy of the organization. The author's egalitarian approach towards the homeless clients, and her lack of involvement in "staff-only" activities, transgress the social class norms within the organizational structure. While the author is successful in gaining the trust of the homeless clients, her approach alienates shelter staff, especially those in the higher echelons of the social hierarchy. The concepts of classism, world views, and Social Identity Theory, are utilized to discuss the dilemma faced by researchers who want to challenge, or work outside, a setting's status quo.     

Global Inequality and International Institutions

This article considers the links between international institutions and global economic justice: how international institutions might be morally important; how they have changed; and at what those changes imply for justice. The institutional structure of international society has evolved in ways that help to undercut the arguments of those who take a restrictionist position towards global economic justice. There is now a denser and more integrated network of shared institutions and practices within which social expectations of global justice and injustice have become more securely established. But, at the same time, our major international social institutions continue to constitute a deformed political order. This combination of density and deformity shapes how we should think about international justice in general and has important implications for the scope, character, and modalities of global economic justice. Having laid out a view of normative development and where it leads, the article then examines why international distributive justice remains so marginal to current practice.     

关于西方心理学中的多元文化论思潮

多元文化论强调文化的多样性。心理学中的多元文化论思潮试图摆脱传统心理学对西方主流文化的依赖性,把心理学建立在多元文化的基础。本文在分析西方心理学中的多元文化论思潮产生原因的基础上阐述了其基本主张,并对这种思潮的意义及未来发展进行了预测。认为它是继行为主义、精神分析和人本主义心理学之后心理学的第四力量。     

Some Fundamentals of Integral Economics

There has been a growing interest in the integration of knowledge but few broad theoretical attempts in the field of economics. If integration is to be taken seriously, combining economic questions with the social and the natural sciences will not suffice. Psychology and the humanities will have to be incorporated, too. Inspired by the works of K. W. Kapp, C. G. Jung, and others, we develop a preliminary framework combining three key “integrative concepts”—(a) social metabolism, (b) the institutional structure, and (c) the inner world—within a perspective characterized by the interior/exterior distinction, evolution, openness, and the dialectics of potentials and actualizations. We argue that these three concepts help to integrate economics with the environment, the collective, and the self and spirituality. For each one of these integrated areas, we highlight some fundamental economic principles, namely (a) the implications of the differentiation of “natural resources,” (b) the signification of the distinction between property and possession, and (c) the need to take into account the unconscious and the individuation process in order to reach a realistic picture of the “economic actor” in search of existential fulfilment. Finally, we suggest sixteen economic propositions that could form a preliminary basis for an integral economics.
