A Latent Growth Curve Modeling Approach to Pooled Interrupted Time Series Analyses

This paper presents a latent variable approach for the estimation of treatment effects within a pooled interrupted time series (ITS) design. Although considered quasi-experimental, the ITS design has been noted as representing one of the strongest alternatives to the randomized experiment, making it highly appropriate for use in documenting the presence of effects that might warrant further evaluation in a large-scale randomized study. Results suggest that the latent variable growth modeling (LGM) is capable of detecting simultaneous differences in both level and slope, and provides tests of significance for these two necessary indicators of an ITS intervention effect. As shown in the analyses, the LGM framework provides a comprehensive and flexible approach to research design and data analysis, making available to a wide audience of researchers an analytical framework for a variety of analyses of growth and developmental processes.     

Exploring the utility of functional analysis methodology to assess and treat problematic verbal behavior in persons with acquired brain injury

Functional analyses were conducted on four adults with acquired brain injuries who regularly displayed instances of inappropriate verbal behavior including depressive, aggressive, suicidal, profane, and sexually inappropriate utterances. After the functional analysis yielded a maintaining variable for each participant, a function‐based intervention consisting of differential reinforcement of alternative verbal behavior was implemented. Results of the behavioral interventions show that instances of vocal behavior can be assessed and subsequently treated using the functional analysis methodology often reserved for nonverbal forms of behavior. The utility of functional analysis for assessing complex human behavior is discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

The Impact of Expert Testimony on Jurors’ Decisions: Gender of the Expert and Testimony Complexity1

The present study investigated whether people used the gender of an expert witness as a heuristic cue to evaluate the evidence presented by the expert. Specifically, the gender of the expert and the complexity of the expert's testimony (low, high) were varied systematically within a simulated civil trial involving an antitrust price‐fixing agreement. It was expected that the male expert would be more persuasive than the female expert, but only when the testimony presented was complex. As predicted, this interaction was revealed across a range of dependent measures. Somewhat unexpected was the finding of a female expert advantage in the low‐complexity condition. The implications of these findings are discussed.     

Episodic Memory in Schizophrenia

Episodic memory impairments in individuals with schizophrenia have been well documented in the literature. However, despite the abundance of findings, constituent cognitive, neural, behavioral, and genetic components of the deficits continue to elude full characterization. This review provides a characterization of these deficits by organizing findings within three frameworks of interest: 1) neuroanatomical; 2) genetic; and 3) behavioral. Within each approach, evidence from imaging studies as well as behavioral studies is examined. The hope is that by synthesizing the cognitive science paradigms, molecular genetic neurophysiological findings, and computational algorithms applied to medial temporal lobe subregions, we will be able to expand our understanding of the types of compromises in episodic memory systems of individuals with schizophrenia.     

Knowing Self Through the Journey: Graduate Students’ Experiences of Self-Knowledge Development

This article explores graduate students’ experiences of a self-knowledge development course that is framed by the Heroic Journey model. Through a consideration of several theorists’ perspectives and through the voices of 13 study participants, this article examines the nature of this self-study experience and its impact on participants’ lives. In light of feminist critiques of the traditional Heroic Journey model, the author pays particular attention to the experiences of women in this course. The author identifies three major findings: First, when the Heroic journey model is understood as a process and not just a theoretical construct, it gains significant power as an inclusive tool for fostering self-knowledge development. Second, self-knowledge development is not solely an individual endeavor. Self-knowledge is socially constructed through interaction with others. Third, self-knowledge development has critical spiritual dimensions, and this deeper level of knowing can lead to significant, long-lasting growth and change.

Use of the Behavioral Assessment System for Children 2nd Edition: Parent Report Scale in Pediatric Cancer Populations

This study examined the use of the Behavioral Assessment System for Children—2nd Edition: Parent Report Scale (BASC-2; Reynolds & Kamphaus, Behavior assessment system for children, 2004) in a pediatric cancer population. Comparisons of scale scores were made between pediatric cancer participants and controls. Within group comparisons were also made between subtypes of pediatric cancer. Parents of 111 children and adolescents who had experienced pediatric cancer completed the BASC-2 as part of larger studies of parent-child adjustment to cancer. Scores on the BASC-2 for cancer survivors were compared to a matched control group. Results from MANOVA analyses revealed that children with cancer were categorized as evidencing more emotional and cognitive complaints compared to the control children. Notably, no significant within group differences emerged on the subscales with regard to cancer subtype. Although preliminary, these results suggest that the BASC-2 can identify the cognitive and emotional differences between cancer survivors and controls.
