Model Fit and Item Factor Analysis: Overfactoring,Underfactoring, and a Program to Guide Interpretation

In exploratory item factor analysis (IFA), researchers may use model fit statistics and commonly invoked fit thresholds to help determine the dimensionality of an assessment. However, these indices and thresholds may mislead as they were developed in a confirmatory framework for models with continuous, not categorical, indicators. The present study used Monte Carlo simulation methods to investigate the ability of popular model fit statistics (chi-square, root mean square error of approximation, the comparative fit index, and the Tucker–Lewis index) and their standard cutoff values to detect the optimal number of latent dimensions underlying sets of dichotomous items. Models were fit to data generated from three-factor population structures that varied in factor loading magnitude, factor intercorrelation magnitude, number of indicators, and whether cross loadings or minor factors were included. The effectiveness of the thresholds varied across fit statistics, and was conditional on many features of the underlying model. Together, results suggest that conventional fit thresholds offer questionable utility in the context of IFA.     

Readers' Theater: A Process of Developing Fourth-Graders' Reading Fluency

This study examines the process of fluency development of three fourth-grade readers of varying reading abilities. Participants were selected based on the number of words they read correctly per minute (WCPM) on the Qualitative Reading Inventory and their score on the Multidimensional Fluency Scale (MFS). Students participated in an 8-week intervention using readers' theater for fluency instruction and practice. Both qualitative and quantitative methods were used. Students were observed during the literacy block of the school day, interviewed three times each, and provided weekly student self-reports. WCPM and MFS scores were recorded weekly. Findings showed inconsistent accuracy scores but documented the progress of students' development in two of the four MFS categories: pace and expression/volume. Motivation and confidence also increased through use of readers' theater.     

Jury Panel Member Perceptions of Interpersonal‐Affective Traits of Psychopathy Predict Support for Execution in a Capital Murder Trial Simulation

Recent research with college undergraduate mock jurors suggests that how psychopathic they perceive a criminal defendant to be is a powerful predictor of whether they will support a death verdict in simulated capital murder trials. Perceived affective and interpersonal traits of psychopathy are especially predictive of support for capital punishment, with perceived remorselessness explaining a disproportionate amount of variance in these attitudes. The present study attempted to extend these findings with a more representative sample of community members called for jury duty (N = 304). Jurors reviewed a case vignette based on an actual capital murder trial, provided sentencing verdicts, and rated the defendant on several characteristics historically associated with the construct of psychopathy. Consistent with prior findings, remorselessness predicted death verdicts, as did the affective and interpersonal features of psychopathy – though the latter effect was more pronounced among jurors who were Caucasian and/or who described their political beliefs as moderate rather than conservative or liberal. Results are discussed in terms of the potentially stigmatizing effects of psychopathy evidence in capital cases. Copyright © 2013 John Wiley & Sons, Ltd.     

Negative self‐imagery in social anxiety contaminates social interactions

Patients with social phobia report experiencing negative images of themselves performing poorly when in feared social situations. The present study investigates whether such negative self‐imagery (based on memory of past social situations) contaminates social interactions. High socially anxious volunteers participated in two conversations with another volunteer (conversational partner). During one conversation, the socially anxious volunteers held in mind a negative self‐image, and during the other they held in mind a less negative (control) self‐image. As predicted, when holding the negative image the socially anxious volunteers felt more anxious, reported using more safety behaviours, believed that they performed more poorly, and showed greater overestimation of how poorly they came across (relative to ratings by the conversational partner). Conversational partners rated the socially anxious volunteers' performance as poorer in the negative image condition. Furthermore, the conversation was contaminated since both groups of participants rated its quality as poorer in the negative image condition.     

Testing the exclusivity effect in location memory

There is growing literature exploring the possibility of parallel retrieval of location memories, although this literature focuses primarily on the speed of retrieval with little attention to the accuracy of location memory recall. Baguley, Lansdale, Lines, and Parkin (2006) found that when a person has two or more memories for an object's location, their recall accuracy suggests that only one representation can be retrieved at a time (exclusivity). This finding is counterintuitive given evidence of non-exclusive recall in the wider memory literature. The current experiment explored the exclusivity effect further and aimed to promote an alternative outcome (i.e., independence or superadditivity) by encouraging the participants to combine multiple representations of space at encoding or retrieval. This was encouraged by using anchor (points of reference) labels that could be combined to form a single strongly associated combination. It was hypothesised that the ability to combine the anchor labels would allow the two representations to be retrieved concurrently, generating higher levels of recall accuracy. The results demonstrate further support for the exclusivity hypothesis, showing no significant improvement in recall accuracy when there are multiple representations of a target object's location as compared to a single representation.     

Social Responsibility Ethics: Doing Right,doing Good,doing Well

The ethics of social responsibility is discussed in reference to six case vignettes drawn from forensic psychology. A definitional model of social responsibility is proposed, and two unequal components of the concept—respect for the individual and concern for social welfare—are identified. The sources of ethical conflict in regard to social responsibility are enumerated. Scholarly criticism of the value orientation of forensic psychology is reviewed, and forensic psychology is contrasted with social policy advocacy efforts made by organized psychology. The social responsibility obligations of psychologists in the microethical sphere, where their actions affect individuals, are diffentiated from the obligations psychology has when operating in the macroethical sphere of social policy. The ethical problems inherent in policy advocacy brought about by individual psychologists working with individuals are underscored: the inevitable element of deception, the violation of role integrity, and the circumvention of social structures and institutions that safeguard the rights of individuals.     

Positive and Negative Religious Beliefs Explaining the Religion–Health Connection Among African Americans

Theory and literature suggests that the reason religiously involved people tend to have good health outcomes is because they have healthy lifestyles and behaviors in accord with religious beliefs. Other literature suggests that religious involvement may play a negative role in health outcomes due to beliefs about illness originating as punishment for sins. These ideas were tested as part of a theoretical model of the religion–health connection in a national sample of African Americans. Outcomes included a variety of health-related behaviors. Study participants (N = 2,370) randomly selected from a U.S. national call list completed a telephone survey assessing religious involvement, health behaviors, and demographic characteristics. Structural equation modeling was used to analyze study data. Findings indicate that perceived religious influence on health behavior mediated the relationship between religious beliefs and behaviors and higher fruit consumption and lower alcohol use and smoking. Belief that illness is the result of punishment for sin mediated the relationship between (a) religious beliefs and higher vegetable consumption and lower binge drinking and (b) religious behaviors and lower vegetable consumption and higher binge drinking. These findings could be applied to health education activities conducted in African American faith-based organizations, such as health ministries, in the effort to eliminate health disparities.     

Attention to Positive and Negative Social-Evaluative Words: Investigating the Effects of Social Anxiety,Trait Anxiety and Social Threat

The study investigated how attention to negative (threatening) and positive social-evaluative words is affected by social anxiety, trait anxiety and the expectation of social threat. High and low socially anxious individuals carried out a modified dot-probe task either while expecting to give a speech or under non-threatening conditions. High socially anxious individuals showed no significant attentional bias towards or away from social-evaluative words. This result significantly contrasted with an identical design that showed avoidance of emotional faces in high socially anxious participants drawn from the same population (Mansell et al ., 1999). Participants who expected to give a speech showed less attentional avoidance of negative and positive social-evaluative words. High trait anxiety was associated with selective attention to negative relative to positive social-evaluative words, consistent with earlier findings of attention to threat cues in high trait-anxious individuals. Implications for designing attention tasks and attentional bias across different dimensions of anxiety are discussed.     

A New Method for Analyzing Data From Visual Artwork

ABSTRACT

This article presents a novel data analytic approach to collect detailed information from visual artworks. This new method provides researchers with a framework to compare, analyze, and review in a systematic way large quantities of data from visual productions. Drawing on principles of art historical criticism, our research team devised a comprehensive coding scheme that captures both technical and content attributes. The coding scheme is configured to record specific, fundamental features for each artwork, providing an instrument for collecting data and cross-examining codes to reveal content in a unique and unbiased manner. For example, detailed data collected through individual codes can reveal clear patterns in the artistic treatment of composition and medium, providing evidence that the method could be adapted and applied for use in a variety of settings. To illustrate the method, this article presents examples from an empirical research study that was conducted at Harvard University's Project Zero. In this study, the coding scheme was applied to 414 pieces of artwork published in a teen art and literary magazine between 1990 and 2011. The coding scheme is defined and applied to 2 sample artworks, allowing readers to understand how this method can be used to record nuanced information about each work. Applying this analytic approach to visual art created in museums and informal learning settings can yield insights into artworks, their creators, and nuanced changes in creative production over time.     

Relationship between Trauma and Risky Behavior in Substance-Abusing Parents Involved in a Family Dependency Treatment Court

This exploratory study examined participants in a Family Dependency Treatment Court (FDTC), designed for substance-abusing parents whose children were removed from the home. Twenty-five participants were interviewed one year after FDTC enrollment to assess retrospectively the relationship between trauma history and risky behaviors. Treatment compliance rates were found to be high, and most participants had negative urinalysis results. Qualitative analyses revealed that approximately half of the participants attributed decreases in risky behaviors to the FDTC program. This study increases understanding of the effect of substance abuse and trauma on high-risk behaviors and might help to improve services for substance-abusing parents involved in the child welfare system. Finally, the future success of reducing child abuse and neglect and parental substance use could hinge on the partnership between judicial and substance abuse treatment through FDTCs. Findings from this exploratory pilot study should be replicated with more representative and larger samples.
