Criterion‐Related Validity of Statistical Operationalizations of Group General Cognitive Ability as a Function of Task Type: Comparing the Mean,Maximum, and Minimum1

The objective of the present study was to investigate the comparative criterion‐related validity of different statistical operationalizations of group general cognitive ability (i.e., mean, maximum, and minimum) as a function of task type based on Steiner's (1966, 1972) task typology. In contrast to recent investigations, we hypothesized that, regardless of task type, the mean of group members’ general cognitive ability would predict group performance as well as or better than other statistical operationalizations of group general cognitive ability. We conducted a laboratory study where 157 four‐person groups worked on 4 tasks that conformed to Steiner's typology (additive, compensatory, conjunctive, and disjunctive). The results indicate that the mean was the strongest predictor of group performance across all 4 task types and, in particular, was significantly stronger than the maximum and minimum on both the disjunctive and conjunctive tasks.     

Identification with Religion: Cross‐National Evidence from a Social Psychological Perspective

Why is religion a more central social identity for some people than for others? Previous studies focus on explaining individual differences in religious affiliation and religiosity, often using the term “identification” in reference to these concepts. Yet, few scholars operationalize—let alone attempt to explain—identification with religion in social psychological terms, i.e., as a construct that captures the subjective psychological centrality of one's religious identity. After underscoring the benefits of exploring religious identification using cross‐national data, we employ an original data set composed of nationally representative surveys in three European countries to model religious identification in two ways: importance (independent strength of attachment) and prominence (prioritization of one's religious identity relative to the others one holds). We document substantial variation in the degree to which individuals define themselves on the basis of their religious identity. We then test predictions drawn from existing theories to model these two measures. Our results extend current understandings of what shapes psychological attachment to religion and raise new questions for future theorization and analysis.     

“This doesn’t look too hard”: A mixed methods exploration of self‐efficacy and sources of self‐efficacy information in a novel puzzle task

Studies have found self‐efficacy to be a key predictor of performance across domains (e.g., Feltz & Magyar, 2006; Judge & Bono, 2001). However, few studies have examined how self‐efficacy and the sources of self‐efficacy information change over time, and most of these studies utilized tasks participants were familiar or experienced with. Therefore, the purpose of this study was to examine how participants weighed and interpreted the sources of self‐efficacy information during initial learning of a novel puzzle task. A secondary aim was to explore differences between student‐athletes and non‐athletes in the sources of self‐efficacy information. Sixty‐three college students completed measures of self‐efficacy, sources of self‐efficacy information, and performed trials of the Tower of Hanoi Puzzle, a wooden puzzle solving test requiring participants to move wooden pieces from one point to another in a specific order. Quantitative results revealed hierarchical performance self‐efficacy for the number of moves required and time required to solve the puzzle significantly changed across the four trials. Qualitative results indicated verbal and imaginal experiences were the two most prominent sources of participants’ self‐efficacy information on trial 1, but by trial 4 mastery experiences and verbal information were the most prominent sources, also suggesting that that the influence of self‐efficacy sources may change over time. Implications for practitioners to assist individuals with novel cognitive tasks are discussed.     

Further investigation of differential reinforcement of alternative behavior without extinction for escape‐maintained destructive behavior

Previous research indicates that manipulating dimensions of reinforcement during differential reinforcement of alternative behavior (DRA) for situations in which extinction cannot be implemented is a potential approach for treating destructive behavior. Therefore, we replicated and extended previous research by determining (a) the conditions under which DRA without extinction decreased and maintained low levels of destructive behavior and (b) whether intervention effects maintained during reinforcement schedule thinning for the alternative response (i.e., compliance). Results showed that effective treatments were developed in the absence of extinction by manipulating the quality of reinforcement for compliance for 2 participants and by combining manipulations of the magnitude and quality of reinforcement for compliance for the other 2 participants. However, maintaining treatment effects during reinforcement schedule thinning required combining the magnitude and quality of reinforcement for 3 of the 4 participants. We discuss the clinical utility of this approach, review limitations of the study, and suggest directions for future research.     

Comparison of components of the Good Behavior Game in a preschool classroom

The Good Behavior Game (GBG) is an effective intervention package for decreasing disruptive behavior in various populations and environments. There is, however, limited research evaluating the GBG with preschoolers. Furthermore, few studies have evaluated the effects of components of the GBG, and of those that have, most have done so only after exposure to the GBG package. We evaluated the effects (a) of the GBG on disruptive behavior of preschoolers during group instruction and (b) the major components of the GBG before and after implementation of the GBG package (c) at both the group and individual level. Results suggest that the GBG package was necessary for decreasing disruptive behavior. However, after exposure to the GBG, a response‐independent contingency was effective for maintaining low levels of disruptive behavior at both the group and individual level.     

Maternal Attributions Related to Compliance with Cystic Fibrosis Treatment

This study examined mothers' attributions related to their children's compliance with various components of medical treatment for cystic fibrosis (CF). Mothers of children with CF were queried regarding adherence rates and reasons for child compliance with chest physiotherapy, inhalation therapy, exercise, medication, and dietary treatments. Maternal attributions for compliance were assessed on the dimensions of parental locus, stability, and controllability. Mothers reported significantly less compliance with diet than with other CF treatments; they also perceived the reasons for compliance with diet and exercise as more external and less under their control. These findings are discussed in relation to parent–child interactions that may be critical to improving treatment adherence, particularly in the context of nutritional interventions.     

Care for Caregivers: Understanding the Need for Caregiver Support

Most long‐term care for older adults in the United States is provided by informal caregivers (Ahmad, 2012 ), the majority of whom experience an intense range of emotions from satisfaction to loneliness. Counselors must consider this emerging population of caretakers and learn methods to encourage clinical services to address their need for support. This article delineates experiences and challenges of informal caregivers and provides suggestions for effective clinical services for caregiver populations.     

South African Serial Homicide: Consistency in Victim Types and Crime Scene Actions Across Series

Key to understanding the significance of behavioural evidence for linkage purposes is in establishing how consistently an offender displays the same or similar behaviours across their series. There have however to date been very few studies aiming at identifying salient components of offending behaviour that can be used reliably for linking individual crimes as part of a single series. In addition, studies that have been conducted have all dealt with serial homicide in the Western world and have been based on small samples of cases from each country. Some of the recent literature has started to disentangle some of these salient features, notably the victim, violence levels, control, and planning. The current study focused on evaluating the consistency of these features across series, using a sample of serial homicides from South Africa consisting of 30 offenders with a total of 283 victims and 235 crime scenes. Results indicate that the level of interaction with the victim may be influential to the stability or instability of offending patterns across the series. How offenders approach planning in their offence also showed a certain degree of consistency, with patterns of violence being the least consistent across the series of all components tested.
