The latent structure of occupations

Triads of occupations were given to 1300 high-school pupils of both sexes in order to find the affinities of the occupations and the values they used to arrive at the affinities. The values used to perceive occupations come from the subject; nevertheless they could be categorized into a scheme of 20 different values, with the residue category containing less than 1% of the answers. In accordance with previous research in this field, an almost universal structure of occupations was found. The following variables had no influence on the choice of occupational affinities: age, trend of study, SES, father's occupation, mother's occupation, vocational maturity, and preferred occupation. Only the pupils of one school were significantly different in affiliating the occupations in the triads. Furthermore, girls perceive the world of occupations more uniformly than boys.Underlying this universal structure of occupations there exists a latent structure, specific to each individual, which explains why the world of occupations is seen in the way it is. This latent structure of occupations is influenced by the individual's specific background.     

Factors influencing the use of internal summary evaluations versus external information in choice

Decision makers cope with more demanding tasks by shifting their cognitive strategies, balancing effort expenditure against the desire to produce an accurate response. In choice tasks, one method for reducing effort while simultaneously maintaining accuracy is to shift from a reliance on information obtained from the external environment to that retrieved from memory, particularly summary evaluations (i.e. relatively stable evaluative reactions to the overall attractiveness of individual alternatives) acquired from previous decision-making experience. We examined four factors that should all encourage decision makers to rely to some extent on internal summary evaluations rather than external information search: (1) increased external search costs, (2) greater time pressure, (3) increased incentives to make an accurate choice, and (4) increased levels of prior experience with the choice context. Sixty experimental subjects chose their preferred alternative from a set of women's magazines. Decision processes were inferred from verbal protocols, computer-generated search records, and decision times. Only increased external search costs led to a greater reliance on summary evaluations. Although increased time pressure, increased incentives, and increased experience with the context did lead to changes in search and evaluation processes, contrary to initial expectations decision makers did not shift to a greater reliance on summary evaluations. These results suggest that while decision makers do sometimes use summary evaluations as a substitute for external search, this is only one of several mechanisms available for effort reduction. Understanding when and where decision makers rely upon summary evaluations probably requires a broader conceptualization of knowledge structures, particularly a consideration of the knowledge that decision makers possess about different choice strategies and their effectiveness.     

Constructing content and delimiting choice: International coverage of KAL Flight 007

For more than two decades, international debate over a New World Communication and Information Order has called attention to the question of whether or not newspapers around the world are limited by the alleged dominance of the international news flow by the Western media. Looking at how six newspapers from around the world covered the 1983 downing of KAL Flight 007 by the Soviet Union, we find that papers are in fact able to shape their coverage of major international events through their choice of providers, their selection and interpretation of subjects and facts, and their use of headlines to emphasize and frame information. Thus, newspapers can delimit choice to suit their own needs and goals.     

Soft constraints in interactive behavior: the case of ignoring perfect knowledge in-the-world for imperfect knowledge in-the-head

Constraints and dependencies among the elements of embodied cognition form patterns or microstrategies of interactive behavior. Hard constraints determine which microstrategies are possible. Soft constraints determine which of the possible microstrategies are most likely to be selected. When selection is non-deliberate or automatic the least effort microstrategy is chosen. In calculating the effort required to execute a microstrategy each of the three types of operations, memory retrieval, perception, and action, are given equal weight; that is, perceptual-motor activity does not have a privileged status with respect to memory. Soft constraints can work contrary to the designer’s intentions by making the access of perfect knowledge in-the-world more effortful than the access of imperfect knowledge in-the-head. These implications of soft constraints are tested in two experiments. In experiment 1 we varied the perceptual-motor effort of accessing knowledge in-the-world as well as the effort of retrieving items from memory. In experiment 2 we replicated one of the experiment 1 conditions to collect eye movement data. The results suggest that milliseconds matter. Soft constraints lead to a reliance on knowledge in-the-head even when the absolute difference in perceptual-motor versus memory retrieval effort is small, and even when relying on memory leads to a higher error rate and lower performance. We discuss the implications of soft constraints for routine interactive behavior, accounts of embodied cognition, and tool and interface design.     

群体讨论过程中信息策略的变化

启发式是人类决策的重要特征,然而对于群体分布式加工条件下的启发式研究却是一个困难的任务。本研究利用多特征多选择决策任务与过程跟踪技术,对群体讨论条件下的启发式决策特点进行研究。结果发现,在群体讨论情景下,决策者的信息呈现策略要更加完全,但决策者的信息搜索负荷并没有因此而增加,群体的各成员之间形成了信息策略上的分布式加工,所以在群体工作情景中的表现出相互依赖性与内隐加工机制。

Effects of information type on children’s interrogative suggestibility: is Theory-of-Mind involved?

This research was aimed at learning more about the different psychological mechanisms underlying children’s suggestibility to leading questions, on the one hand, and children’s suggestibility to negative feedback, on the other, by distinguishing between interview questions concerning different types of information. Results showed that, unlike the developmental pattern of children’s suggestibility to leading questions, the developmental pattern of children’s suggestibility to negative feedback differed depending on whether the interview questions concerned external facts (physical states and events) or internal facts (mental states and events). This difference was not manifested in response to questions concerning central versus peripheral facts. Results are interpreted in terms of the hypothesis that children’s suggestibility to negative feedback is differently affected by “Theory-of-Mind” abilities than children’s suggestibility to leading questions. Further research is needed in order to test this hypothesis.     

General information in relevant logic

This paper sets out a philosophical interpretation of the model theory of Mares and Goldblatt (The Journal of Symbolic Logic 71, 2006). This interpretation distinguishes between truth conditions and information conditions. Whereas the usual Tarskian truth condition holds for universally quantified statements, their information condition is quite different. The information condition utilizes general propositions. The present paper gives a philosophical explanation of general propositions and argues that these are needed to give an adequate theory of general information.     

Persistence of emphasis in language production: A cross-linguistic approach

This study investigates the way in which speakers determine which aspects of an utterance to emphasize and how this affects the form of utterances. To do this, we ask whether the binding between emphasis and thematic roles persists between utterances. In one within-language (Dutch-Dutch) and three cross-linguistic (Dutch-English) structural priming experiments, we measured persistence effects for four different Dutch transitives (actives, PP-initial passives, PP-medial passives, and PP-final passives). Whereas English allows only one passive (PP-final passive), Dutch allows three different variants with the same functional assignment, but different constituent structures. Additionally, the degree of emphasis on the agent differs significantly between the PP-initial passive and the other passives (Experiment 1). Experiment 2 showed persistence of actives, PP-medial, and PP-final passives in Dutch, but no priming between passives with different constituent structures. Experiments 3 and 4, however, showed that both PP-medial and PP-final passives prime the use of English passives. Experiment 5 confirmed that the emphasis on thematic roles persists: the proportion of passives in the PP-initial passive condition fell midway between the proportions produced in the active and PP-medial passive condition.     

Money can’t buy love: Asymmetric beliefs about gift price and feelings of appreciation

Across three studies, we identify an asymmetry between gift-givers’ and gift-recipients’ beliefs about the link between gift price and feelings of appreciation. Gift-givers expected a positive correlation between how much they spent on a gift and the extent to which gift-recipients would appreciate the gift because gift-givers assume that more expensive gifts convey a higher level of thoughtfulness. Gift-recipients, in contrast, reported no such association between gift price and their actual feelings of appreciation. This effect occurred regardless of whether the individual’s role and the magnitude of the gift were manipulated or measured in the field. Taken together, these findings cast doubt on whether gift-givers can draw on their personal experience as gift-recipients in order to identify meaningful gifts for others.
