Our learning-by-teaching environment, Betty's Brain, captures a wealth of data on students' learning interactions as they teach a virtual agent. This paper extends an exploratory data mining methodology for assessing and comparing students' learning behaviors from these interaction traces. The core algorithm employs sequence mining techniques to…

Few follow-up studies of parasuicides in the literature focus on changes in underlying psychopathology. This study compared a group of parasuicides who mastered their presenting problems within 3 months after the key episode with a group who had not and examined some of the underlying psychopathology and its relationship to repetition of suicidal…

Research has revealed a considerable degree of stability of Type A behavior from adolescence to adulthood. Other research has reported an association between anger and certain dimensions of cardiovascular risk in adolescent subjects. Such findings suggest that further study of the Type A phenomenon as it is expressed in adolescents may enhance…

The Type A construct, which consists of such psychological components as a sense of time urgency, competitive aggressiveness, and easily aroused hostility wich are manifested under appropriately challenging circumstances, has been studied to a great extent in adult white males. There is less research, however, on how these characteristics are…

Certain characteristics of a Taylor (1965) competitive reaction time task contribute to a lack of awareness of contingencies that exist between two aggressors. The opponent's contingent response to the subject's specific shock setting may be obscured by the reaction time competition, thus concealing the matching contingency. Nine separate steps…

The ways in which fathers and mothers communicate with and teach their 6-month-old first-born infants were compared. Twenty-two white, middle class mothers and fathers were videotaped interacting with their infants (11 male, 11 female) on 10 tasks. Trained observers coded the parents' interaction with their infants on the following variables:…

A study investigated whether the interaction patterns of high consensus groups differed significantly from the patterns of low consensus groups in the final stage of a decision-making task. Eighty-four college students placed into 19 groups were told to select a social problem, investigate it, and develop a solution. At the end of the three-week…

A study investigated the extent to which the gender and social status of the complimenter as well as the gender of the receiver account for the choice of strategy Americans and Thais use to respond to compliments. Subjects were 40 American university students in the United States and 40 Thai students in Thailand. In a discourse-completion test,…

Little evidence exists about either the short or long-term effects of coping strategies on the reduction of emotional distress or the lessening of problems. To examine the predictors and effectiveness of four marital coping efforts (negotiation, optimistic comparison, selective ignoring, and resignation), data derived from a panel study of 758…

The role of environmental stimuli in the control of cigarette smoking has been the object of theoretical speculation, but there have been few experimental demonstrations of the control exerted over smoking by environmental events. Self-report data on smoking in the natural environment were compared to observations made of smoking among subjects…

Patterns of student performance were examined in a personalized instruction (PSI) course. Introductory psychology students (N=65) were randomly divided into a completely self-paced group and a group that had an early, instructor-imposed deadline. It was hypothesized that the early deadline group would respond at a more even pace throughout the…

This study identified differences and similarities among the perceptions of adult and adolescent community members regarding drug use patterns and practices. A written questionnaire was administered to 5,128 adolescents from grades 7 through 12 in the rural inland northwest, and a similar questionnaire was administered to over 900 adults in the…

Little is known about the Type B behavior pattern which is allegedly antithetical to the coronary-prone Type A pattern. The purpose of this study was to develop a descriptive profile of individuals in middle adulthood who exhibit the Type B pattern. Cognitive/attitudinal characteristics, stress reactivity, and health status were examined in 98…

Two hypotheses were posed in a study that examined the communicative consequences of structured versus nonstructured tasks on subjects with varying levels of communication apprehension (CA): (1) task structure and level of CA will interact to predict behavioral disruption in dyads, and (2) CA and evaluation will interact to predict behavioral…

Kruglanski's endogenous-exogenous partition, when applied to reasons given by smokers for smoking cigarettes, distinguishes two types of actions: (1) endogenous reasons implying that the behavior of consuming the cigarette is the goal of the action and the actor is positive toward the behavior, and (2) exogenous reasons implying that the behavior…
