Structural equation models merge multiple regression, path analysis, and factor analysis techniques into a single data analytic framework. Measurement models are developed to define latent variables, and structural equations are then established among the latent variables. Explains the development of these models. (KS)

Develops a causal model that explains over 40% of the variance in matriculation mathematics achievement of mature internal and external students at the University of Papua New Guinea. Background variables seem more important in the learning of mathematics compared to mediating variables for external students than for internal students. (MDH)

Explores causal attributions of success and failure as functions of religious orientations among a sample of Polish university students. Participants assessed secular and religious attributions on three dimensions: controllability, stability, and locus. Finds that religious and non-religious participants attributed both success and failure to…

Uses a causal model to understand the direct and mediated effects of neighborhood disadvantage and family structure on youth expectations. Demonstrates that the employment expectations of adolescents are significantly lower in both nonintact and welfare homes in comparison to youth in other households. Discusses implications for social policy in…

Three studies examined the relationship between specific forms of preschoolers' social and pretend play and divergent/convergent problem solving. Naturalistic and experimental designs were used to provide clearer account of relationship and to challenge assumption of single direction of influence. Results support complex reciprocal causality model…

Tests the hypothesis that two general developmentally-based levels of hypothesis-testing skills exist. Finds a positive relationship between level of hypothesis-testing skill and performance on a transfer problem involving the test of a hypothesis based on unobservable entities. Also finds a positive relationship between level of…

This study investigates the causal coherence of deaf students' written narratives and the relation between students' use of causal structures in narrative writing and their linguistic skills. The written narratives of 17 deaf high school students were compared with those of 2 groups of hearing writers: 17 high school students and 16 second…

The psychological model of organizational commitment (OC) has been extensively investigated in U.S. workers (Near, 1989), but less frequently applied in cross-personality studies. The investigation proposes a model of turnover intentions (TI) that uses locus of control (LOC) as a moderator. A causal model and a firm-specific sample were used to…

The current studies explore causal models of heart attack and depression generated from American healers whom use distinct explanatory frameworks. Causal chains leading to two illnesses, heart attack and depression, were elicited from participant groups: registered nurses (RNs), energy healers, RN energy healers, and undergraduates. The…

Background: Attention deficit/hyperactivity disorder (ADHD) is one of the most prevalent and commonly studied forms of psychopathology in children and adolescents. Causal models of ADHD have long implicated dysfunction in fronto-striatal and frontal-parietal networks supporting executive function, a hypothesis that can now be examined…

Archaeologists have used material artifacts found in a physical space to gain an understanding about the people who occupied that space. Likewise, as users wander through a digital library, they leave behind data-based artifacts of their activity in the virtual space. Digital library archaeologists can gather these artifacts and employ inductive…

The standard approach guiding research on the relationship between categories and causality views categories as reflecting causal relations in the world. We provide evidence that the opposite direction also holds: categories that have been acquired in previous learning contexts may influence subsequent causal learning. In three experiments we show…

This article is a condensed report of a 3-year empirical study exploring best policies and practices of urban educational reform, focusing on 22 major urban school districts that were involved in the Urban Systemic Initiative (USI) program, sponsored by the National Science Foundation. USI has been a catalyst for large-scale educational reform in…

Numerous studies show that happy individuals are successful across multiple life domains, including marriage, friendship, income, work performance, and health. The authors suggest a conceptual model to account for these findings, arguing that the happiness-success link exists not only because success makes people happy, but also because positive…

The purpose of this paper is to discuss the development of research questions in mixed methods studies. First, we discuss the ways that the goal of the study, the research objective(s), and the research purpose shape the formation of research questions. Second, we compare and contrast quantitative research questions and qualitative research…
