Areas of Interest as a Signal Detection Problem in Behavioral Eye‐Tracking Research

Decision researchers frequently analyze attention to individual objects to test hypotheses about underlying cognitive processes. Generally, fixations are assigned to objects using a method known as area of interest (AOI). Ideally, an AOI includes all fixations belonging to an object while fixations to other objects are excluded. Unfortunately, due to measurement inaccuracy and insufficient distance between objects, the distributions of fixations to objects may overlap, resulting in a signal detection problem. If the AOI is to include all fixations to an object, it will also likely include fixations belonging to other objects (false positives). In a survey, we find that many researchers report testing multiple AOI sizes when performing analyses, presumably trying to balance the proportion of true and false positive fixations. To test whether AOI size influences the measurement of object attention and conclusions drawn about cognitive processes, we reanalyze four published studies and conduct a fifth tailored to our purpose. We find that in studies in which we expected overlapping fixation distributions, analyses benefited from smaller AOI sizes (0° visual angle margin). In studies where we expected no overlap, analyses benefited from larger AOI sizes (>.5° visual angle margins). We conclude with a guideline for the use of AOIs in behavioral eye‐tracking research.

Comparison of Explicit Forgiveness Interventions With an Alternative Treatment: A Randomized Clinical Trial

Forgiveness interventions can help people forgive past offenses. However, few studies have compared forgiveness interventions with genuine alternative treatments. The authors compared forgiveness interventions with a therapeutic alternative treatment. Participants reduced unforgiveness and increased forgiveness regardless of treatment condition. Trait forgivingness was not related to change in forgiveness, whereas greater offender contrition was related to greater reductions in unforgiveness. The type of treatment may not be as important as factors common to the interventions.     

Perceived strengths of urban girls and boys experiencing homelessness

Homelessness, with concomitant poverty and mobility, is often associated with multiple negative outcomes for school‐aged children; less is known about the positive characteristics of children experiencing homelessness. This study focused on understanding the mother‐perceived strengths of 50 elementary school‐aged children experiencing homelessness. Mothers typically identified multiple child strengths, even among children experiencing emotional or behavioural difficulties. These strengths included positive personality and behavioural characteristics, intelligence and academic achievement and positive physical attributes. Implications for intervention and further research are discussed. Copyright © 2008 John Wiley & Sons, Ltd.     

Changes in the Composition of the Homeless Population: 1992–2002

This study examines changes in the characteristics of the homeless population before and after a period of extended economic expansion (1992–2002). Data from other sources suggest that, during this 10-year period, the size of the overall population of homeless persons may have declined slightly, though not significantly, both in the city studied and nationally. In-depth surveys of representative samples of homeless adults (N = 249 in 1992–94; N = 220 in 2000–2002) revealed significant differences in the composition of the homeless population across the time period, consistent with queuing theory. Persons experiencing homelessness after the expansion appeared to be a more “chronic,” less readily employable population than those interviewed at the start of the expansion: Those interviewed after were older, spent more time living on the streets, had more health symptoms, were more likely to have a diagnosis of schizophrenia, and had more restricted social networks and social support. Policy, research, and service provision implications of the findings are discussed.     

A Brief Proof of the Full Completeness of Shin’s Venn Diagram Proof System

In an article in the Journal of Philosophical Logic in 1996, “Towards a Model Theory of Venn Diagrams,” (Vol. 25, No. 5, pp. 463–482), Hammer and Danner proved the full completeness of Shin’s formal system for reasoning with Venn Diagrams. Their proof is eight pages long. This note gives a brief five line proof of this same result, using connections between diagrammatic and sentential representations.     

A Therapeutic Model of Self‐Forgiveness With Intervention Strategies for Counselors

Self‐forgiveness is associated with psychological and relational well‐being and may be a worthwhile treatment goal for clients who have hurt others. The authors utilized theoretical and empirical literature to describe a 4‐component therapeutic model of self‐forgiveness—responsibility, remorse, restoration, and renewal—and offer suggestions for promoting each component with clients. Finally, the authors explore potential contraindications and the applicability of self‐forgiveness for military veterans, clients in substance abuse treatment, and clients convicted of a crime.
