Name or hum that tune: Feeling of knowing for music

This is the first reported research that explores the feeling of knowing (FOK) for musical stimuli. Subjects attempted to recall melodies and titles of musical pieces, made FOK ratings when recall failed, and then had a recognition test. With instrumental music (Experiment 1), more titles were recalled when melodies were given as cues than vice versa. With songs whose lyrics were not presented (Experiment 2), however, more melodies were recalled than were titles. For nonrecalled items, although the overall levels of recognition did not differ, FOK ratings were higher for titles than for melodies in Experiment 1, and the opposite pattern occurred in Experiment 2. In both experiments, the FOK ratings predicted melody recognition more accurately than they did title recognition.     

Undefinability of propositional quantifiers in the modal system S4

We show that (contrary to the parallel case of intuitionistic logic, see [7], [4]) there does not exist a translation fromS4² (the propositional modal systemS4 enriched with propositional quantifiers) intoS4 that preserves provability and reduces to identity for Boolean connectives and □.     

Formal systems for modal operators on locales

In the paper [8], the first author developped a topos- theoretic approach to reference and modality. (See also [5]). This approach leads naturally to modal operators on locales (or spaces without points). The aim of this paper is to develop the theory of such modal operators in the context of the theory of locales, to axiomatize the propositional modal logics arising in this context and to study completeness and decidability of the resulting systems.     

Roles of cognitive load and self-relevance during emotional information searching on decision-making

Older adults have been found to favor positive stimuli over negative stimuli; further, developing a negative preference may be a cognitively demanding process. In the present study, we focused on the joint effects task self-relevance and cognitive load have on older adults' emotional information preferences when performing decision-making. To examine this, we used multi-attribute decision tasks and process-tracing procedure to measure their searching process. The study composed of a 2 (age: young/old) × 2 (cognitive load: load/non-load) × 3 (attribute valence: positive/neutral/negative) × 3 (task self-relevance: high/medium/low) mixed design. Sixty-one young adults and 62 older adults viewed 5 (alternatives) × 5 (attributes) decision matrices that contained positive, negative, and neutral information, with the total views and mean time spent viewing each different valence (positive, negative, and neutral information) set as dependent variables. The results indicated that both young and old adults have no emotional information preference in regard to self-relevance. When under no cognitive load, both positive and negative information were viewed more than neutral information; however, under cognitive load, preference for negative information decreased; this effect size was more robust in older adults. There was also a main effect of self-relevance on total views and mean checking time, with attributes concerning higher self-relevance tasks being more likely to attract attention. Older adults exhibited a consistent hedonic focus, even in highly self-relevant contexts; however, this effect disappeared under cognitive load. Overall, the findings suggest that cognitive resources play an important role in emotional information processing during decision processes.     

To buy or to sell: cultural differences in stock market decisions based on price trends

Four studies compared the stock market decisions of Canadians and Chinese. In two studies using simple stock market trends, compared with Chinese, Canadians were more willing to sell and less willing to buy falling stock. But when the stock price was rising, the opposite occurred: Canadians were more willing to buy and less willing to sell. A third study showed that for complex stock price trends, Canadians were strongly influenced by the most recent price trends: they tended to predict that recent trends would continue and made selling decisions without considering the rest of the trend patterns; whereas the Chinese made reversal predictions for the dominant trends and made decisions that took both recent and early trends into consideration. Study 4 replicated the finding with experienced individual investors. These findings are consistent with the previous literature on different lay theories of change held by Chinese and North Americans. Copyright © 2008 John Wiley & Sons, Ltd.     

身体锻炼对高中学生主观幸福感的影响及其心理机制

为了考察身体锻炼与高中学生主观幸福感的关系,采用量表法进行了研究,控制了相关变量后的研究结果表明:(1)经常锻炼的高中学生比锻炼不足的高中学生的主观幸福感更加强烈,这一差异表现在两者之间的情感成份和特殊生活满意感上;一次的身体锻炼对高中学生主观幸福感没有影响,长期性的身体锻炼可以提高高中学生主观幸福感;小锻炼量和中等锻炼量的身体锻炼随着锻炼持续时间的增长,对高中学生主观幸福感影响加深,而大锻炼量随着锻炼持续时间的增长对高中学生主观幸福感的影响,呈现倒“V”型的曲线状;随着锻炼持续时间的增长,中等锻炼量的效果明显优于小锻炼量和大锻炼量的效果;(2)身体锻炼不仅可以直接对高中学生主观幸福感产生影响,而且可以通过身体自尊,人际关系、人格等中介变量对高中学生主观幸福感产生影响
