Misconstruals Or More? The Interactions Of Orbit Diagrams And Explanations Of The Seasons, Victor R. Lee Apr 2010

Misconstruals Or More? The Interactions Of Orbit Diagrams And Explanations Of The Seasons, Victor R. Lee

Instructional Technology and Learning Sciences Faculty Publications

This paper examines a “misconstrual hypothesis” regarding diagrams of the Earth’s orbit around the sun and how middle school students explain the cause of the seasons. Drawing from 24 semi-structured interviews, I present qualitative analyses of students’ explanations of why temperatures vary in summer and winter and how those are influenced by the elliptical shape of perspective drawings of the Earth’s orbit, common to many science textbooks. The results of the analysis suggest that diagram interpretation does not necessarily follow what has been often predicted in the literature and that conceptualizations can shift quite rapidly as different diagram features are …


A Delay-Discounting Primer, Gregory J. Madden, Patrick S. Johnson Jan 2010

A Delay-Discounting Primer, Gregory J. Madden, Patrick S. Johnson

Psychology Faculty Publications

Given the importance of research findings and the potential of further research to aid in the prediction and control of impulsivity, the primary focus of this chapter (and this book) is on choice and the failure of future events to affect current decisions. In this primer chapter, we consider two types of impulsive choice: (a) preferring a smaller-sooner reward while forgoing a larger-later one and (b) preferring a larger-later aversive outcome over a smaller-sooner one. The first of these is exemplified by the toy-pilfering child with whom we opened this chapter. Taking the toy is immediately rewarded, but it is …


Discounting And Pathological Gambling, Nancy M. Petry, Gregory J. Madden Jan 2010

Discounting And Pathological Gambling, Nancy M. Petry, Gregory J. Madden

Psychology Faculty Publications

Pathological gambling is a disorder characterized by excessive gambling. It often occurs in conjunction with substance use disorders, and research is beginning to examine the association between these disorders, especially with regard to impulsivity and discounting. In this chapter, we initially review the diagnosis and prevalence rates of pathological gambling, including its comorbidity with substance use disorders. We then describe relations between personality measures of impulsivity and pathological gambling. Gamblers' patterns of choices on the Iowa Gambling Task (IGT) and measures of delay and probability discounting are covered in depth, and we discuss the degree to which these choices are …
