Considering an interactive computer as a social stimulus suggests that contemporary social psychological theories can contribute to the prediction of user attitude and performance. In order to assist in the systematic exploration of this possibility, we developed DIALOGUE, an on-line system to investigate the effects of varying the computer’s responses to the user. This system involves a presentation program that displays the computer’s responses, performs the pacing of video information, and collects a variety of measurements, including the user’s response time and the number of correct/incorrect user responses. DIALOGUE also includes a data manager that allows the experimenter to examine or modify the information collected by the presentation program. Utilizing DIALOGUE, we conducted a preliminary investigation of one aspect of human-computer interaction, the effects of varying the degree of human-like responses exhibited by the computer. Results suggest that (1) there are underlying dimensions of judgment involving perception of interactive computers, (2) a manipulation of human-like computer responses is reflected primarily in certain of these dimensions, and (3) such a manipulation influences user performance and feelings of responsibility. Factors related to the implementation of DIALOGUE are considered, and its potential for investigations of a variety of human-computer interactions is discussed. 相似文献

Sinusoidal gratings of various spatial frequencies were used as masking stimuli in a detection task and a vernier acuity task. The test stimuli were 1 cycle/deg square-wave gratings. The spatial frequency of the most effective mask was 1 cycle/deg for the detection task but 3 cycles/deg for the vernier acuity task. The different masking functions for the two tasks show that the visual system analyzes the square-wave stimulus into its various spatial-frequency components. Since the test stimulus was the same for both tasks, the different masking functions may be the result of an attentional mechanism that weighs the importance of the output from various spatial-frequency analyzers. Whether the information from a particular spatial-frequency analyzer is attended or not depends upon the task the visual system must perform. 相似文献

Repeated measurements of episodic memory are needed for monitoring amnestic mild cognitive impairment (aMCI) and mild Alzheimer’s disease (AD). Most episodic memory tests may pose a challenge to patients, even when they are in the milder stages of the disease. This cross-sectional study compared floor effects of the Visual Association Test (VAT) and the Rey Auditory Verbal Learning Test (RAVLT) in healthy elderly controls and in patients with aMCI or AD (N = 125). A hierarchical multiple regression analysis was used to examine whether linear or quadratic trends best fitted the data of cognitive test performance across global cognitive impairment. Results showed that VAT total scores decreased linearly across the range of global cognitive impairment, whereas RAVLT total scores showed a quadratic trend, with total scores levelling off for 90% of aMCI patients and 94% of AD patients. We conclude that the VAT shows few if any floor effects in patients with aMCI and mild AD and is therefore a potentially promising cognitive test for monitoring episodic memory impairment. 相似文献

An empirically corroborated model of proenvironmental commitments is outlined. According to this model, willingness to contribute to the saving of global commons (atmosphere, oceans, etc.) is motivated by the awareness of global ecological risks, by perceived injustices of the distributions of benefits and costs resulting from exploiting and polluting activities, and by the conviction that many actors—ordinary citizens as well as powerful authorities in business and politics—have both effective means and responsibilities to contribute to the protection of the environment. Political implications are drawn from the typical attributional pattern of multi‐responsibility for environmental protection and from the perception of distributive injustices of the current overuse and pollution of commons. Basic issues of ecological justice are discussed. 相似文献

This conceptual paper examines the promises and critical challenges posed by contemporary personality measurement using big data. More specifically, the paper provides (i) an introduction to the type of technologies that give rise to big data, (ii) an overview of how big data is used in personality research and how it might be used in the future, (iii) a framework for approaching big data in personality science, (iv) an exploration of ideas that connect psychometric reliability and validity, as well as principles of fairness and privacy, to measures of personality that use big data, (v) a discussion emphasizing the importance of collaboration with other disciplines for personality psychologists seeking to adopt big data methods, and finally, (vi) a list of practical considerations for researchers seeking to move forward with big data personality measurement and research. It is expected that this paper will provide insights, guidance, and inspiration that helps personality researchers navigate the challenges and opportunities posed by using big data methods in personality measurement. © 2020 European Association of Personality Psychology 相似文献

Older cities struggling with issues of survival focus on jobs and the economy, but competition requires all cities to pay
attention to the quality of life that attracts residents. Creating such an inviting environment includes “third places” that
foster community and communication among people outside of home and work, yet we have little empirical evidence that speaks
to the subject, or their importance for a community’s quality of life. Here we report on a national U.S. survey that asked
people to identify such places in their community, producing a wide variety of “third places” that ranged from the most popular
community centers, coffee shops and restaurants to parks and malls. While a few relationships are found between population/diversity
and the popularity of particular third places, the most important result confirms a hypothesized relationship between perceptions
that third places are accessible in their community and the perceived quality of life. 相似文献

Rough‐and‐tumble play (RTP) is a common form of play between fathers and children. It has been suggested that RTP can contribute to the development of selfregulation. This study addressed the hypothesis that the frequency of father–child RTP is related to the frequency of physically aggressive behavior in early childhood. This relationship was expected to be moderated by the dominance relationship between father and son during play. Eighty‐five children between the ages of 2 and 6 years were videotaped during a free‐play session with their fathers in their homes and questionnaire data was collected about father–child RTP frequency during the past year. The play dyads were rated for the degree to which the father dominated play interactions. A significant statistical interaction revealed that RTP frequency was associated with higher levels of physical aggression in children whose fathers were less dominant. These results indicate that RTP is indeed related to physical aggression, though this relationship is moderated by the degree to which the father is a dominant playmate. Aggr.

This paper presents the results of an analysis of the lexical term ‘querer’ (want) qua genuine reference to desire. The instances of ‘querer’ to be analyzed were taken from the naturally occurring speech of monolingual speakers of Spanish. Specifically, a database of 24,558 child utterances taken from the CHILDES system was analyzed. This corpus yielded 444 utterances with the desire term ‘querer’. The utterances belong to several children whose ages range from 21 to 46 months. The results of this study support the hypothesis that children consistently refer to desire at around 2 years of age and that children undergo a marked increase in their reference to this concept at 36 months of age, although it is not yet clear whether they start referring to their own desires before those of someone else. 相似文献

This paper aims to explain how the Tractatus attempts to unifylogic by deriving the truth-functionality of logical necessityfrom the thesis that a proposition shows its sense. I first interpret the Tractarian notion of showing as the displaying ofwhat is intrinsic to an expression (or a symbol). Then I argue that, according to theTractatus, the thesis that a proposition shows its sense implies the determinacy of sense, the possibility of the complete elimination of non-primitive symbols, the analyticity thesis and the strong analyticity thesis. The picture theory emerges as what provides the only acceptable account of an elementary proposition, subject to the constraint that a proposition must show its sense. The picture theory and the analyticity thesis then entail the contingency thesis (that an elementary proposition is contingent) and the independence thesis (that elementary propositions are mutually logically independent) which, together with the strong analyticity thesis, imply that all logical propositions are tautologies. 相似文献
