BEWILDERMENT AND THEREAFTER: Some Reflections in Response to Lee Yearley

The following reflections were originally an oral response to issues raised in Lee Yearley's presentation in May 2009 at Harvard Divinity School. As written here, they follow upon his oral and now written comments, highlighting key issues and points for development, drawing on this respondent's expertise in comparative and Hindu studies.     

Do health beliefs about COVID-19 predict morbidity? A longitudinal study

In a highly powered (N ≈ 5000), six-months longitudinal study (December 2020-May 2021), we tested the assumption that beliefs concerning COVID-19 and the precautions against it predicted morbidity. Six months after having filled out a survey measuring beliefs about the disease and the precautions against it, participants reported if they were or had been ill with COVID-19. A lower likelihood of being or having been ill with COVID-19 was predicted by personal optimism concerning infection, perceived personal control over infection, perceived effectiveness of precautions, and self-reported personal or better-than-average adherence to the precautions. A higher likelihood of being or having been ill with COVID-19 was predicted by perceived personal control over a good outcome of an infection, egocentric impact perception concerning the impact of the disease, perceived difficulty of adherence to the precautions, and both personal and egocentric impact perception concerning the impact of the precautions. Comparative optimism did not predict morbidity, nor did personal optimism concerning severe disease or a good outcome, perceived personal control over severe disease, and moralization of the precautions. We discuss implications for public health communication.     

Generalized Rough Sets (Preclusivity Fuzzy-Intuitionistic (BZ) Lattices)

The standard Pawlak approach to rough set theory, as an approximation space consisting of a universe U and an equivalence (indiscernibility) relation R U x U, can be equivalently described by the induced preclusivity ("discernibility") relation U x U \ R, which is irreflexive and symmetric.We generalize the notion of approximation space as a pair consisting of a universe U and a discernibility or preclusivity (irreflexive and symmetric) relation, not necessarily induced from an equivalence relation. In this case the "elementary" sets are not mutually disjoint, but all the theory of generalized rough sets can be developed in analogy with the standard Pawlak approach. On the power set of the universe, the algebraic structure of the quasi fuzzy-intuitionistic "classical" (BZ) lattice is introduced and the sets of all "closed" and of all "open" definable sets with the associated complete (in general nondistributive) ortholattice structures are singled out.The rough approximation of any fixed subset of the universe is the pair consisting of the best "open" approximation from the bottom and the best "closed" approximation from the top. The properties of this generalized rough approximation mapping are studied in the context of quasi-BZ lattice structures of "closed-open" ordered pairs (the "algebraic logic" of generalized rough set theory), comparing the results with the standard Pawlak approach. A particular weak form of rough representation is also studied.     

A Logic for Reasoning about Relative Similarity

A similarity relation is a reflexive and symmetric binary relation between objects. Similarity is relative: it depends on the set of properties of objects used in determining their similarity or dissimilarity. A multi-modal logical language for reasoning about relative similarities is presented. The modalities correspond semantically to the upper and lower approximations of a set of objects by similarity relations corresponding to all subsets of a given set of properties of objects. A complete deduction system for the language is presented.     

Parallel lives: Community psychology in Latin America and the United States

Comparing the history of community psychology as it developed in the U.S. during the 1960s with the community psychology that developed 10 years later in Latin America, one is reminded of the title of Plutarch’s masterpice,Parallel Lives. Although there was very little contact or communication between the first community psychologists in these regions, very similar principles and orientations evolved. These similarities are particularly striking given the many ways in which the U.S. and Latin American contexts and histories differ. Since most readers are expected to be familiar with the history of community psychology as it developed in the U.S., this paper focuses primarily on the development of community psychology in Latin America in order to highlight areas of convergence as well as divergence from the U.S. experience. This paper is based on an address presented at the Fourth Biennial Conference, Society for Community Research and Action, Division 27 of the American Psychological Association, William and Mary College, Williamsburg, Virginia, 1993.

The second offspring of General Process Learning Theory: Overt behavior as the ambassador of the mind

Wasserman suggested in a recent book review that the study of intervening cognitive processes represents a current focus of interest in animal learning and that this has led to a revitalization of comparative psychology. An examination of the volume reviewed suggests that he may have overstated the case. Most of the authors to whom he refers expressed dissatisfaction with traditional stimulus-response associationism but few argued for the extreme (information processing) sort of cognitive approach described by Wasserman.     

Choosing what to choose from: Preference for inclusion over exclusion when constructing consideration sets from large choice sets

Decision making is a two‐stage process, consisting of, first, consideration set construction and then final choice. Decision makers can form a consideration set from a choice set using one of two strategies: including the options they wish to further consider or excluding those they do not wish to further consider. The authors propose that decision makers have a relative preference for an inclusion (vs. exclusion) strategy when choosing from large choice sets and that this preference is driven primarily by a lay belief that inclusion requires less effort than exclusion, particularly in large choice sets. Study 1 demonstrates that decision makers prefer using an inclusion (vs. exclusion) strategy when faced with large choice sets. Study 2 replicates the effect of choice set size on preference for consideration set construction strategy and demonstrates that the belief that exclusion is more effortful mediates the relative preference for inclusion in large choice sets. Studies 3 and 4 further support the importance of perceived effort, demonstrating a greater preference for inclusion in large choice sets when decision makers are primed to think about effort (vs. accuracy; Study 3) and when the choice set is perceived as requiring more effort because of more information being presented about each alternative (vs. more alternatives in the choice set; Study 4). Finally, Study 5 manipulates consideration set construction strategy, showing that using inclusion (vs. exclusion) in large choice sets leads to smaller consideration sets, greater confidence in the decision process, and a higher quality consideration set.     

语法的进化连续性及进化起源解释

语法是人类交流系统有别于其他动物的关键特征之一。行为比较研究表明, 除人类外的其他灵长目动物也能理解并掌握抽象的顺序排序规则; 神经生物学比较研究表明, 支持排序处理的神经机制来自人类与其他灵长目动物共同具有的脑区。因此语法所依赖的序列学习能力在人类与其他灵长目动物间具有进化连续性。词汇限制假说、事件感知假说与自我驯化假说分别从不同角度对人类语法的进化起源进行了解释。未来研究需要探讨人工语法任务中所发现的脑神经机制是否是层级结构加工的通用处理器, 并进一步澄清语义加工与语法加工的关系。
