The purpose of this study was to propose and test a motivational model of high school dropout. The model posits that teachers, parents, and the school administration's behaviors towards students influence students' perceptions of competence and autonomy. The less autonomy supportive the social agents' behaviors are, the less positive the students' perceptions of competence and autonomy. In turn...

An experiment was conducted to test the relationships between users' perceptions of a computerized system's beauty and usability. The experiment used a computerized application as a surrogate for an Automated Teller Machine (ATM). Perceptions were elicited before and after the participants used the system. Pre-experimental measures indicate strong correlations between system's perceived aesthet...

Many accounts of social influences on exercise participation describe how people compare their behaviors to those of others. We develop and test a novel hypothesis, the exercise rank hypothesis, of how this comparison can occur. The exercise rank hypothesis, derived from evolutionary theory and the decision by sampling model of judgment, suggests that individuals' perceptions of the health bene...

This research tested a path model for how rural high school students’ self-perceptions and environmental perceptions influence their course-related interest, school engagement, and ultimately, post-graduation intentions. Participants were 414 students in all four grades, in 10 rural, public high schools. Correlation and path analyses (in LISREL 8.58) were utilized to identify significant paths ...

Does natural selection favor veridical perceptions, those that more accurately depict the objective environment? Students of perception often claim that it does. But this claim, though influential, has not been adequately tested. Here we formalize the claim and a few alternatives. To test them, we introduce "interface games," a class of evolutionary games in which perceptual strategies compete....

This paper reports the investigation of the effectiveness of Problem-Based Learning (PBL) within a web-based environment in the delivery of an undergraduate Physics course. The effectiveness was evaluated by comparing the performances and the perceptions of the sample students (n=67) using the web-based PBL and comparing the outcomes with those of the web-based Content-Based Learning (CBL). The...

The purpose of this study was to examine the benefits of youth participation in a sport-based youth development summer program, the National Youth Sport Program (NYSP). This study also identified areas of programmatic strength within the program, as well as areas for improvement. 193 participants in NYSP completed a pre- and post-test that assessed belonging, social competence, athletic compete...

The most common measurements in the task-based usability evaluation paradigm include behavioral (e.g., completion times or errors) and subjective measures (e.g., ratings). Previous work has shown that success and performance in the test tasks do not dictate subjective usability perceptions, which instead are affected by appraisals of the system such as those of its aesthetic appeal. While these...

BACKGROUND Because risk perceptions can affect protective behavior and protective behavior can affect risk perceptions, the relations between these 2 constructs are complex and incorrect tests often lead to invalid conclusions. PURPOSE To discuss and carry out appropriate tests of 3 easily confused hypotheses: (a). the behavior motivation hypothesis (perceptions of personal risk cause people ...

Using a stratified random sampling procedure, we interviewed 200 residents of Beirut, Lebanon and surrounding areas in order to test predictions of a dual process model of prejudice. We examined the role of social dominance orientation (SDO) and right-wing authoritarianism (RWA) in predicting prejudice toward Americans, mediating the relationships between personality dimensions and prejudice, a...
