Dialogue theory, although it has ancient roots, was put forward in the 1970s in logic as astructure that can be useful for helping to evaluate argumentation and informal fallacies.Recently, however, it has been taken up as a broader subject of investigation in computerscience. This paper surveys both the historical and philosophical background of dialoguetheory and the latest research initiatives on dialogue theory in computer science. The main components of dialogue theory are briefly explained. Included is a classification of the main types of dialogue that, it is argued, should provide the central focus for studying many important dialogue contexts in specific cases. Following these three surveys, a concluding prediction is made about the direction dialogue theory is likely to take in the next century, especially in relation to the growing field of communication studies. 相似文献

Data for 422 methadone treatment clients in the National Treatment Improvement Evaluation Study (NTIES) were analyzed. Clients maintained continuously in methadone treatment for longer than 12 months and clients who leftbetween 3–12 months were compared with clients treated for less than 3 months. Additionally, clients treated for 3–12 months who had short follow-up periods (6-month average) were compared with 3–12-month clients with long follow-up periods (11-month average). Positive treatment outcomes includinglower drug use, reduced risk of viral infectionand sexually transmitted disease (through needle sharing and multiple sex partners), and less criminality wereassociated with both longer duration treatment and shorter follow-up periods. The findings suggested that continuous methadone treatment of 12 or more months is optimal, whereas stays of less than3 months may be ineffective. Furthermore, stays of 3–12 months are likelyto be beneficial over a relatively short time span, for example 6 months. 相似文献

Shortly after viewing a video of a theft, 5‐ and 7‐year‐old children and adults were interviewed with free recall and either misleading or unbiased‐leading questions. After a 2‐day delay, participants were interviewed with free recall and recognition questions administered by either the same or a different interviewer. Results from day 1 replicate previous findings with levels of recall and resistance to suggestibility increasing with age. Counter to predictions, correct recognition performance on day 2 was greater for some participants interviewed by the same as opposed to a different interviewer, and incorrect recognition was greater for all groups of participants for those interviewed by a different as opposed to the same interviewer. Results are discussed in terms of the role of context dependence on memory performance. Copyright © 2000 John Wiley & Sons, Ltd. 相似文献

In his commentary, Richardson criticizes the analysis of the relationship between socio-economic status (SES) and memory performance as presented by Herrmann and Guadagno (1997). Richardson's criticism addresses Herrmann and Guadagno's procedures for classifying economic backgrounds of subjects and the statistics they used to analyze the effects of SES and memory. We believe that all of these points are worth considering but suggest that it is too early in this research area to definitively settle on either (a) the best procedure for classifying SES or (b) the most effective statistical method for post-hoc analysis of memory data. The underlying issues are too complex and the number of investigations too few to argue that one procedure or method is right and the other wrong. Alternatively, Richardson's commentary agrees with ours in two important ways. Richardson's article and ours both assert that economic background is clearly a relevant variable in explaining memory performance. In addition, both articles recommend that memory and cognitive researchers take account of economic well being in future memory research. Copyright © 1998 John Wiley & Sons, Ltd. 相似文献

To explore genetic-developmental differences in the biobehavioral effects of induced illness, males from two lines of mice selectively bred for high or low levels of aggressive behavior were injected with endotoxin (Escherichia coli, LPS: 0.25 mg/kg, 1.25 mg/kg, or 2.5 mg, i.p.) or saline. Body temperature, weight, and locomotor activity were monitored immediately before and 8 and 24 hr after injection. Twenty-four hours after injection, social behaviors were assessed in a 10-min dyadic test, and hypothalamus, spleen, and serum were collected. In both lines, endotoxin treatment increased behavioral immobility ("freezing") and decreased social exploration. Other effects showed line differences: Males from the high-aggressive line had a lower threshold to endotoxin-induced effects on body temperature, weight loss, spleen weight, and corticosterone. Social reactivity (startle response to mild social investigation) increased in the high-aggressive line and decreased in the low-aggressive line after treatment. In the high-aggressive line only, endotoxin decreased attack frequency and increased latency to attack. The interactions between selected line (genotype) and endotoxin treatment (environment) demonstrate that genetic-developmental differences in social and aggressive behavior may indicate the extent to which immune stimuli (e.g., bacteria, viruses, cytokines) function as "biobehavioral stressors."

Measures of salivary testosterone and the personality dimensions of aggression and pro-social behavior were obtained in 306 (155 male and 151 female) university students. Each participant provided two samples of saliva and completed ten self-report personality scales from multiple inventories. A factor analysis of the personality scales produced two factors, an aggression factor and a pro-social behavior factor. Men averaged five times the amount of salivary testosterone as women (99 pg/ml vs. 18.5 pg/ml) and rated themselves as more aggressive and less nurturant. Within each sex, testosterone was positively correlated with aggression and negatively correlated with pro-social personality. Structural equation modelling analyses suggested that a direct effect model best described the relationship between salivary testosterone and the latent personality dimensions of aggression and pro-social behavior. © 1996 Wiley-Liss, Inc. 相似文献

Facilitating people's ability to anticipate, prepare for and recover from disaster is an important component of the UNISDR strategy for disaster risk reduction. Following a discussion of the functional characteristics of preparedness, this paper first discusses how hazard characteristics and psychological constructs influence people's ability to anticipate uncertain future events. It then reviews how psychological theories (Health Belief Model, Protection Motivation Theory, PrE Theory, Theory of Planned Behaviour, Critical Awareness Theory, Social Marketing, Protective Action Decision Model, Social Capital, Community Engagement Theory and Social Identity Theory) can inform understanding of preparedness for likely and current hazard events. Discussion then then turns to applying concepts and theories to understanding preparedness for current disasters. The all-hazards and cross-cultural applicability of preparedness theory is discussed, as are a need for a critical appraisal of preparedness, its predictors, and the nature and development of the preparedness process and its application in facilitating effective intervention strategies. 相似文献

The present study aimed at improving our understanding of the role of neuropsychological deficits in preschool Attention Deficit Hyperactivity Disorder (ADHD). The study included 52 children in the ADHD group and 72 controls (age 4–6 years). Both laboratory measures and teacher reports of executive deficits (i.e., working memory, inhibition, and shifting), delay-related behaviors (i.e., the preference for minimizing delay), and emotional functions (i.e., emotion recognition and regulation) were included. Variable-oriented analyses were complemented with person-oriented analyses (i.e., identifying the proportion of patients considered impaired). Results showed that the ADHD group differed from controls with regard to all measures of executive functioning and most measures of delay-related behaviors, but few differences were found for emotional functioning. A substantial subgroup (23%) of children with ADHD did not have a neuropsychological deficit in any domain. There were subgroups with executive or delay-related deficits only, but no pure emotional subgroup. The overlap between different neuropsychological deficits was much larger when teacher reports were used as opposed to laboratory measures. Regarding functional impairments, large mean differences were found between the ADHD group and controls. However, neuropsychological deficits were not able to explain individual variations in daily life functioning among children with ADHD. In conclusion, the present study identified some important methodological and theoretical issues regarding the role of neuropsychological functioning in preschool ADHD. 相似文献
