消失文本条件下注视点右侧词对中文阅读影响的眼动研究

采用消失文本范式,考察在中文阅读过程中注视点右侧词对阅读的影响。实验一发现,若读者所注视的双字词及其右侧词在80ms后同时消失,则会对其正常阅读产生干扰。实验二排除了当前注视词消失可能存在的效应,即让右侧词在80ms后单独消失,结果仍发现会干扰正常阅读。另外,在两个实验中均发现了显著的词频效应。这些结果不仅支持眼动的认知控制模型,还证实注视点右侧词的加工对顺利阅读具有重要性。     

Haybron on Mood Propensity and Happiness

Daniel Haybron has made an original contribution to philosophical discussions of happiness. He has put forward a theory that identifies happiness with moods and the propensity to experience moods. Haybron’s contribution deserves a critical examination. The first section of my paper is interpretive. I show how Haybron uses the concepts of ‘central affective states’ and ‘mood propensity’ to define happiness. The second and third sections of the paper are critical. They focus on the inclusion of mood propensity in Haybron’s theory. In the second section I argue that his theory fails because there is an example that shows a subject can be happy even when that subject does not have a positive mood propensity. In the third section of the paper, I consider Haybron’s objection that the case in question is ‘object-specific’ and that it is not ‘emotionally-based’. I discuss both of these technical terms in detail. Moreover, I argue that a modified version of the counter example accommodates these technical terms while retaining the persuasiveness of the original example.

The Conceptual Complexity of Central Bankers and the Asian Financial Crisis

This paper examines the impact of the conceptual complexity of central bankers on exchange rate volatility during the Asian Financial Crisis of the late 1990s. Theoretically, this paper develops a framework to study the cognitive style of individual central bankers in conjunction with the institutional features of the central banks they head. The paper also controls for a variety of other common explanations for exchange rate volatility during this time period, including the number of veto players representing the political system and underlying structural features of the Asian economies. Empirically, the cross-sectional time-series analysis finds that more conceptually complex central bankers were able to reduce exchange rate volatility during the crisis years, especially when they inhabited highly independent central banks. This paper concludes that linking the study of key individuals to macroeconomic outcomes in the global political economy is a promising area of research.     

The social and cultural roots of political violence in Central America

The paper suggests that there are specific features of violence, both personal and organized that have roots in the cultural formation of the Central American peoples. Its focus is on the three neighboring countries of Guatemala, Honduras, and El Salvador and on the ideological violence of the twentieth century. The paper considers various aspects of the social character of the Spanish Americans of this area, their concepts of manliness, and their religion, as these affect both rich and poor, and contrasts these features with the attitudes of the indigenous Indian community. Having established that political violence is endemic in the region, the paper considers the role of Hispanic culture in shaping this violence. Emphasis is placed on the notion of machismo, which is identified not with pleasure seeking but with defiance of death. The attitudes of the people of this area toward death shape their attitudes toward violence. They are shown to have a fascination with the instruments of death, especially the machete among the lower classes and the gun among the university students. These attitudes are contrasted with the relatively non-violent attitudes of the Indians. The studies cited in this paper show the Indians as less interested in competition and aggression that the Hispanic population. In the last analysis, the violence of the Central American is intensely personal and can be shown to derive from the basic social and cultural fabric of the society.     

Synergistic influences of sensory and central stimuli on non-voluntary rhythmic arm movements

In recent years, neuromodulation of the cervical spinal circuitry has become an area of interest for investigating rhythmogenesis of the human spinal cord and interaction between cervical and lumbosacral circuitries, given the involvement of rhythmic arm muscle activity in many locomotor tasks. We have previously shown that arm muscle vibrostimulation can elicit non-voluntary upper limb oscillations in unloading body conditions. Here we investigated the excitability of the cervical spinal circuitry by applying different peripheral and central stimuli in healthy humans. The rationale for applying combined stimuli is that the efficiency of only one stimulus is generally limited. We found that low-intensity electrical stimulation of the superficial arm median nerve can evoke rhythmic arm movements. Furthermore, the movements were enhanced by additional peripheral stimuli (e.g., arm muscle vibration, head turns or passive rhythmic leg movements). Finally, low-frequency transcranial magnetic stimulation of the motor cortex significantly facilitated rhythmogenesis. The findings are discussed in the general framework of a brain-spinal interface for developing adaptive central pattern generator-modulating therapies.     

Stuttering theory,research, and therapy: A five-year retrospective and look ahead

This article reviews events in stuttering theory, research, and therapy that have transpired during the past 5 years. After the retrospective review, current work in the area of stuttering is examined. This analysis of the past and present was conducted in an effort to give clearer direction to future efforts to understand the disorder, and to study and treat it more effectively.     

Relation of Type A behavior to performance and satisfaction among sales personnel

Many of the personal characteristics frequently associated with successful sales performance are very similar to behaviors which are a part of the Type A coronary-prone behavior pattern. This study investigated the relationship between Type A behavior and sales performance, as well as job satisfaction, among a sample of 355 life insurance agents. No significant differences were found between Type A and B agents and three measures of sales performance and one measure of general job satisfaction. Type A behavior among the sample was associated with measures of stress and number of health complaints. Possible explanations for the lack of Type A-performance and Type A-satisfaction relationships are discussed as is the importance of the association with stress and health complaints.     

Deontic Reasoning With Emotional Content: Evolutionary Psychology or Decision Theory?

Three experiments investigated the contrasting predictions of the evolutionary and decision-theoretic approaches to deontic reasoning. Two experiments embedded a hazard management (HM) rule in a social contract scenario that should lead to competition between innate modules. A 3rd experiment used a pure HM task. Threatening material was also introduced into the antecedent, p, of a deontic rule, if p then must q. According to the evolutionary approach, more HM responses (Cosmides & Tooby, 2000) are predicted when p is threatening, whereas decision theory predicts fewer. All 3 experiments were consistent with decision theory. Other theories are discussed, and it is concluded that they cannot account for the behavior observed in these experiments.     

Discrimination of polysyllabic sequences by one- to four-month-old infants

The goal of this research was to ascertain the effects of suprasegmental parameters (fundamental frequency, amplitude, and duration) on discrimination of polysyllabic sequences by 1- to 4-month-old infants. A high-amplitude sucking procedure, with synthesized female speech, was used. Results indicate that young infants can discriminate the three-syllable sequences [marana] versus [malana] when suprasegmental characteristics typical of infant-directed speech emphasize the middle syllable. However, infants failed to demonstrate discrimination when adult-directed suprasegmentals were used and in several other experimental conditions in which prosodic parameters were manipulated. The pattern of results obtained in the six experiments suggests that the exaggerated suprasegmentals of infant-directed speech may function as a perceptual catalyst, facilitating discrimination by focusing the infant's attention on a distinctive syllable within polysyllabic sequences.
