Analyzing student motivation at the confluence of achievement goals and their underlying reasons: an investigation of goal complexes

This research investigated the interrelations among achievement goals and the underlying reasons for pursuing them. To do so, it utilized the framework of goal complexes, which are regulatory constructs defined at the intersection of aims and reasons. Data from two independent large samples of New Zealand university students showed that across types of reasons, namely development versus demonstration of competence/ability, and approach-avoidance tendencies pertaining to aims and reasons, respectively, participants rated lowest items mapping normative aims. Additionally, for most non-normative achievement goals, which in this study were related to task and own past performance, students endorsed more strongly items pertaining to the development rather than the demonstration of competence/ability. This pattern of results was reversed for approach—but not avoidance—related reasons associated with normative aims. These findings are largely consistent with the tenets of cognitive dissonance theory and have important implications for pedagogical practice, policy development, and the study of self-evaluation and cognitive processes. In addition, they delineate new directions for fruitful future research.     

Does adolescent heavier alcohol use predict young adult aggression and delinquency? Parallel analyses from four Australasian cohort studies

While the association between heavy alcohol consumption and aggression has been well documented, the causal direction of this association, particularly at a population level, is disputed. A number of causal sequences have been proposed. First, that aggression leads to heavy alcohol use. Second, that heavy alcohol use leads to aggression. Third, that the association between alcohol use and aggression is due to confounding by (a) sociodemographic variables or (b) delinquency. We report here data from four Australasian prospective longitudinal studies of adolescents, to assess the temporal sequence of heavy drinking and aggression over the period from adolescence to young adulthood. The four cohort studies provide a total sample of 6,706 persons (Australian Temperament Project, n = 1701; Christchurch Health and Development Study, n = 931; Mater-University of Queensland Study of Pregnancy, n = 2437; Victorian Adolescent Health Cohort Study, n = 1637). We use multinomial logistic regression to determine whether early adolescent aggression predicts subsequent age of onset of heavy episodic drinking (HED), after adjustment for concurrent sociodemographic factors and delinquency. We then consider whether HED predicts subsequent aggression, after adjusting for past aggression, concurrent delinquency, and a range of confounders. There are broadly consistent findings across the four cohort studies. Early aggression strongly predicts subsequent HED. HED predicts later aggression after adjustment for prior aggression and other confounders. Policies that alter population levels of alcohol consumption are likely to impact on levels of aggression in societies where HED linked to aggression is more common.     

Effects of a televised smoking cessation intervention among low-income and minority smokers

In November 1985, a television smoking cessation program was broadcast for 20 days on the noon and 9 p.m. news. Smokers in West Garfield Park, an inner-city impoverished area of Chicago, were randomly assigned either to a comprehensive intervention or to a no-intervention control condition. Although 100,000 self-help manuals had been distributed throughout Chicago, none of the controls in this low-income area had obtained a manual. The intervention consisted of providing the smokers a self-help manual, the televised broadcast, weekly support meetings, and supportive phone calls. At a 4-month follow-up, 20% of treatment participants were abstinent compared to 9% of controls. The results indicated that intensive supplementary opportunities enhanced participation by low-income smokers in a media smoking cessation program.     

Team-Track: A tool for investigating tracking performance in teams

Team performance and coordination have gained considerable interest in disparate fields (e.g., aviation, process control, medicine, and wartime operations). Team-Track, a C program that allows controlled experimental manipulation of team conditions, was developed to meet the research needs resulting from this interest. Using Team-Track, one can manipulate task interdependence, team staffing, relative contributions of team members, communications, and informational displays in a low-cost environment. The dependent measure of performance generated by the program is the absolute tracking error along each dimension. The program is ideal for investigating team interactions as it allows for orthogonal manipulation of team variables, therefore accommodating a multitude of research paradigms.     

PC operating system for measuring discrete biological responses during classical conditioning

A software package, written in C source code for MS-DOS 5.0 or higher IBM-compatible computers, was developed for the classical conditioning of discrete biological responses. The program’s primary functions include collecting and storing conditioning parameters, controlling presentation of stimuli, transforming discrete analog responses into dependent measures (e.g., CR frequencies and various measures of response topography), and generating data sets for use with commercial PC statistical packages. These functions were implemented in a windows-based user interface to increase the experimenter’s ease of use and to maximize efficiency in performing experimental procedures. Scrollable windows provide detailed visual displays that permit monitoring responses during conditioning and a review of each trial after the session is over. Additional software tools aid the visual inspection of response topographies, data manipulation, and calibration of the experimental apparatus. An overview of the system, its design objectives, and the user interface is presented.
