Relative preference for distinct reinforcers maintaining destructive behavior

The literature offers few recommendations for sequencing exposure to treatment conditions with individuals with multiply maintained destructive behavior. Identifying relative preference for the functional reinforcers maintaining destructive behavior may be one means of guiding that decision. The present study presents a preliminary attempt at developing a robust relative preference and reinforcer assessment for individuals with multiply maintained destructive behavior. Guided and free-choice trials were implemented in which participants chose between two multiple-schedule arrangements, each of which programmed signaled periods of isolated reinforcer availability and unavailability. Consistent participant choice and responding during free-choice trials was then used to thin the corresponding schedule of reinforcement. The results demonstrated a strong preference for one of the two functional reinforcers for all four participants, yet preferences differed across participants and were not well predicted by responding in prior analyses.     

The tool for the automatic analysis of lexical sophistication (TAALES): version 2.0

This study introduces the second release of the Tool for the Automatic Analysis of Lexical Sophistication (TAALES 2.0), a freely available and easy-to-use text analysis tool. TAALES 2.0 is housed on a user’s hard drive (allowing for secure data processing) and is available on most operating systems (Windows, Mac, and Linux). TAALES 2.0 adds 316 indices to the original tool. These indices are related to word frequency, word range, n-gram frequency, n-gram range, n-gram strength of association, contextual distinctiveness, word recognition norms, semantic network, and word neighbors. In this study, we validated TAALES 2.0 by investigating whether its indices could be used to model both holistic scores of lexical proficiency in free writes and word choice scores in narrative essays. The results indicated that the TAALES 2.0 indices could be used to explain 58% of the variance in lexical proficiency scores and 32% of the variance in word-choice scores. Newly added TAALES 2.0 indices, including those related to n-gram association strength, word neighborhood, and word recognition norms, featured heavily in these predictor models, suggesting that TAALES 2.0 represents a substantial upgrade.     

Learning nonwords: the Hebb repetition effect as a model of word learning

Page and Norris [(2008). Is there a common mechanism underlying word-form learning and the Hebb repetition effect? Experimental data and a modelling framework. In A. Thorn &; M. P. A. Page (Eds.), Interactions between short-term and long-term memory in the verbal domain; (2009). A model linking immediate serial recall, the Hebb repetition effect and the learning of phonological word forms. Philosophical Transactions of the Royal Society B: Biological Sciences, 364(1536), 3737–3753. doi:10.1098/rstb.2009.0173] have suggested that the Hebb [(1961). Distinctive features of learning in the higher animal. In J. F. Delafresnaye (Ed.), Brain mechanisms and learning (pp. 37–46). Oxford: Blackwell] repetition paradigm can be considered as a laboratory analogue of word learning. In Hebb learning experiments, the lists of items to be learned are presented as discrete sequences. In contrast, novel words are, by definition, always heard as a single coarticulated whole. Might this undermine the claim that Hebb learning can shed light on word learning? Here we report an experiment comparing learning sequences of isolated syllables with learning the same sequences spoken as a single coarticulated nonword. The pattern of learning was similar in the two cases, suggesting that the Hebb repetition paradigm can indeed provide valuable insights into the way novel word forms are learned.     

An experiential thinking style: its facets and relations with objective and subjective criterion measures

In Study 1, an experiential factor divided into the following 3 factors when 3 or more factors were extracted: intuition, emotionality, and imagination; whereas a rational factor retained its coherence. In Study 2, an experiential but not a rational thinking style was positively associated with performance measures of creativity, humor, aesthetic judgment, and intuition and with self-report measures of empathy and social popularity. A rational thinking style was associated with several measures of adjustment. Both thinking styles were positively related to personal growth. Support was provided from several sources for the discriminant validity of the experiential facets. In a third study, the independence of the 2 thinking styles and of gender differences in self-reported data were verified by observations by others of participants' thinking styles. The importance of identifying facets of an experiential thinking style and of discovering previously unrecognized favorable attributes of this thinking style was discussed.     

The structure of the Beck Hopelessness Scale: A confirmatory factor analysis in UK students

The aim of this paper was to confirm the factor structure of the 20-item Beck Hopelessness Scale in a non-clinical population. Previous research has highlighted a lack of clarity in its construct validity with regards to this population.Based on previous factor analytic findings from both clinical and non-clinical studies, 13 separate confirmatory factor models were specified and estimated using LISREL 8.72 to test the one, two and three-factor models.Psychology and medical students at Queen’s University, Belfast (n = 581) completed both the BHS and the Beck Depression Inventory (BDI).All models showed reasonable fit, but only one, a four-item single-factor model demonstrated a non-significant chi-squared statistic. These four items can be used to derive a Short-Form BHS (SBHS) in which increasing scores (0-4) corresponded with increasing scores in the BDI. The four items were also drawn from all three of Beck’s proposed triad, and included both positively and negatively scored items.This study in a UK undergraduate non-clinical population suggests that the BHS best measures a one-factor model of hopelessness. It appears that a shorter four-item scale can also measure this one-factor model.     

Ageism,Sensation-Seeking,and Risk-Taking Behavior in Young Adults

The research investigated the relationships among ageism, sensation-seeking, and risk-taking in young adults. Recent research has shown that young adults reporting higher levels of ageist attitudes and ageist behaviors also report higher levels of risk-taking in daily life than those with less ageist attitudes and behaviors (Popham et al. in press). The results are consistent with terror management theory; young adults may attempt to buffer their death anxiety by seeking out experiences that make them feel strong and invulnerable (i.e., taking risks). In contrast, prior research has shown that there is a link between risk-taking and sensation-seeking and that individuals may be biologically predisposed to be high sensation-seekers (Zuckerman Behavioural and Brain Sciences 7:413–471, 1984; Neuropsychobiology 13:121–128, 1985). In a study with 475 undergraduates, we investigated the relationships among ageism, sensation-seeing, and risk-taking behavior. The results showed that ageist behavior and two dimensions of sensation-seeking (i.e., Disinhibition and Experience Seeking) were significant predictors of risk-taking. Implications for practical approaches to reduce risk-taking in young adults are discussed.     

Effect size measures for mediation models: quantitative strategies for communicating indirect effects

The statistical analysis of mediation effects has become an indispensable tool for helping scientists investigate processes thought to be causal. Yet, in spite of many recent advances in the estimation and testing of mediation effects, little attention has been given to methods for communicating effect size and the practical importance of those effect sizes. Our goals in this article are to (a) outline some general desiderata for effect size measures, (b) describe current methods of expressing effect size and practical importance for mediation, (c) use the desiderata to evaluate these methods, and (d) develop new methods to communicate effect size in the context of mediation analysis. The first new effect size index we describe is a residual-based index that quantifies the amount of variance explained in both the mediator and the outcome. The second new effect size index quantifies the indirect effect as the proportion of the maximum possible indirect effect that could have been obtained, given the scales of the variables involved. We supplement our discussion by offering easy-to-use R tools for the numerical and visual communication of effect size for mediation effects.     

Congregations and Crime: Is the Spatial Distribution of Congregations Associated with Neighborhood Crime Rates?

Few studies have focused on how religious congregations are associated with crime rates, especially at the neighborhood level. Using data for more than 400 block groups in Indianapolis, we focus on the relationship between different types of congregations (e.g., evangelical Protestant, civically engaged) and eight different types of crime controlling for a variety of neighborhood characteristics. The results suggest that neighborhoods with more evangelical Protestant congregations have higher rates of both violent and property crimes. Neighborhoods with more mainline and black Protestant congregations have higher rates of property crimes, but not violent crimes. Finally, although civically engaged congregations are associated with lower neighborhood crime rates, the association may be limited to some types of property crimes. Therefore, the positive association between evangelical Protestant congregations and crime may be more general, and the negative association between civically engaged congregations and crime more limited, than previous research has suggested .     

WOMEN'S RESPONSES TO UNWANTED SEXUAL ADVANCES: THE ROLE OF ALCOHOL AND INHIBITION CONFLICT

In this study we investigated how alcohol consumption affects women's responses to unwanted sexual advances in a hypothetical dating situation. Sixty female social drinkers participated in a 2 × 2 between-subjects experiment, which examined the effects of moderate alcohol intoxication and relationship characteristics on behavioral responses to unwanted sexual advances. Hypotheses were tested regarding the influence of inhibition conflict on intoxicated participants. As predicted, intoxicated women were more likely than sober women to consent to their dating partner's sexual advances in high conflict situations. Additionally, alcohol consumption increased women's estimated likelihood of responding passively. These findings aid in explicating the relationship between alcohol consumption and women's increased vulnerability to sexual assault.
