THE EFFECT OF CORRELATED ARTIFACTS AND TRUE VALIDITY ON THE ACCURACY OF PARAMETER ESTIMATION IN VALIDITY GENERALIZATION

The effect of non-zero intercorrelations among the three artifacts (criterion reliability, predictor reliability, and range restriction on the predictor) and true validity on the accuracy of estimation in two validity generalization models (Model 1and Model 2) was investigated. Only the Thylor Series Approximation 1(TSA1) procedure from Model 1 and the procedure with complete sample-based artifact data from Model 2 were included in this study. Six intercorrelation conditions (zero, low positive, medium positive, low negative, low negative and positive, and medium negative and positive) and two distributions of artifacts were used in this investigation. The two major conclusions from this study are: (a) Both models yielded reasonably accurate estimates of the mean of true validities (M_ρ) and (b) only Model 2 produced accurate estimates of the variance of true validities (V_ρ). The need for additional research for accurately estimating V_ρ when the three artifacts and true validity are correlated is recommended.     

Developmental differences in the use of task goals in a cued version of the stroop task

The ability of children (M= 8.8 years) and adults (M= 25.6 years) to maintain task goals was examined by comparing their performance on a cued version of the Stroop colour‐word task. The experimental task presented a cue on each trial that instructed the participant to either read aloud the forthcoming word or name the colour of the word's lettering. Participants were tested with each of two cue‐stimulus delays (1,000 and 5,000 ms). Analysis of error rates in the colour‐naming condition revealed that children experienced greater interference than adults at each of the cue‐stimulus delays. In an effort to separate the relative contributions of colour‐naming and word‐reading processes, additional analyses were performed based on the process dissociation procedure of Lindsay and Jacoby (1994) . While colour‐naming process estimates did not vary with age group or cue‐stimulus delay, word‐reading process estimates were found to vary with age group and cue‐stimulus delay. Specifically, adults were superior to children in the inhibition of irrelevant word information only during a long cue‐stimulus delay. Collectively, these findings indicate that children have difficulty maintaining task goals in order to suppress stronger, goal‐irrelevant responses.     

Quantifying the effects of the differential outcomes procedure in humans: A systematic review and a meta‐analysis

We present a systematic review and a meta‐analysis comparing the differential outcomes procedure to a nondifferential outcomes procedure among clinical and nonclinical populations. Sixty distinct experiments were included in the systematic review, 43 of which were included in the meta‐analysis. We calculated pooled effect sizes for accuracy (overall accuracy, test accuracy, transfer accuracy) and acquisition outcomes (latency, errors, and trials to mastery). The meta‐analysis revealed significant medium‐to‐large effect sizes for all three accuracy measures (pooled effect size range, 0.57 to 1.30). We found relatively greater effect sizes among clinical populations (effect size = 1.04). The single‐subject experimental literature included in the systematic review was consistent with the findings from the group studies, demonstrating improvements in accuracy and speed of learning for the majority of participants. Moderator and subgroup analyses suggest that discrimination difficulty may induce relatively larger differential outcomes effects. The results indicate that the differential outcomes procedure can be a valuable addition to reinforcement‐based interventions.     

Personality and team performance: a meta‐analysis

Using a meta‐analytical procedure, the relationship between team composition in terms of the Big‐Five personality traits (trait elevation and variability) and team performance were researched. The number of teams upon which analyses were performed ranged from 106 to 527. For the total sample, significant effects were found for elevation in agreeableness (ρ = 0.24) and conscientiousness (ρ = 0.20), and for variability in agreeableness (ρ = ?0.12) and conscientiousness (ρ = ?0.24). Moderation by type of team was tested for professional teams versus student teams. Moderation results for agreeableness and conscientiousness were in line with the total sample results. However, student and professional teams differed in effects for emotional stability and openness to experience. Based on these results, suggestions for future team composition research are presented.

Pyramidal parent training using behavioral skills training: Training caregivers in the use of a differential reinforcement procedure

Six caregivers participated in a research study in which behavioral skills training (BST) was used within a pyramidal training model to train a differential reinforcement of an alternative behavior (DRA) procedure. Physical prompting was utilized to obtain correct responses across the identified alternative behavior. The caregivers were split into two tiers, comprised of three caregivers each. The experimenter trained tier‐one caregivers, who then trained tier‐two caregivers after meeting a predetermined mastery criterion. A multiple baseline design across participants research design was used to evaluate the effectiveness of correct implementation of the DRA procedure, demonstrating experimental control across participants. During baseline, caregivers did not implement DRA correctly. Following training, tier‐one and tier‐two caregivers demonstrated correct implementation of the DRA and prompting procedure. Intervention score was (M = 96%), from a baseline score of (M = 34.6%), for tier‐one participants. Intervention score was (M = 96.6%), from a baseline score of (M = 33%), for tier‐two participants. A follow‐up maintenance probe demonstrated correct implementation of the DRA procedure with prompting across both tiers of trained caregivers.     

Commitment in relationships: An updated meta‐analysis of the Investment Model

This article provides a systematic review and updated meta‐analysis of the extant literature on Rusbult's Investment Model of Commitment. This meta‐analysis aimed to determine the strength of the associations between commitment and its antecedents and to investigate potential moderators of these associations. This meta‐analysis included 50,427 participants from 202 independent samples (collected between 1980 and early 2016) that had examined the intercorrelations between satisfaction, investment size, quality of alternatives, and commitment. Across all studies, satisfaction had the largest aggregate association with commitment (r = 0.65), followed by investments (r = 0.53) and quality of alternatives (r = ?0.43). Several significant moderators of the relationships between the antecedents and commitment were also identified. Implications and future research directions are discussed.     

Applying Western models of volunteering in Hong Kong: The role of empathy,prosocial motivation and motive–experience fit for volunteering

The present research investigates the applicability of prominent Western volunteering frameworks in Hong Kong. Two cross‐sectional surveys involving a total of 268 respondents were conducted. In Study 1, we tested a model of volunteering among 149 Hong Kong Chinese adult individuals (M_age = 34.8 years; 51.7% female) that examines antecedents and outcomes of voluntary engagement. Results show that prosocial motivation relates to volunteering, and that volunteering in turn predicts life satisfaction. Unexpectedly, and unlike studies in Western settings, other‐oriented empathy was not related to volunteering. Study 2 tests the propositions of the Volunteer Process Model (VPM) among 119 Hong Kong Chinese volunteers (M_age = 36.9 years; 58.0% female). Findings largely support the VPM: our results indicate that the link between motives, voluntary service length and frequency is mediated by satisfaction with volunteering. Moreover, findings suggest that a fit between motives and experience seems relevant for increasing volunteers' satisfaction with their service. Results of both studies suggest that Western volunteering models can be applied to volunteering in East Asian cultures when culture‐specific adaptations are considered.     

Relations among personality scales of aggression,violence, and empathy: Validational evidence bearing on the risk of eruptive violence scale

This study was designed to explore relations of emotional empathy (two scales) with aggression and violence (three scales). An initial study investigated validity of one of the violence scales, the Risk of Eruptive Violence Scale (REV), by comparing individual REV scores with individual histories of criminal violence for a sample of incarcerated juveniles. Validity of the REV was supported by a very strong correlation of .71 between REV scores and the amount of criminal violence in this homogeneous sample. The second study yielded positive intercorrelations among measures of aggression and violence, positive intercorrelations among measures of emotional empathy, and negative correlations (ranging from –.22 to –.50, P < .05) of measures of aggression and violence with measures of emotional empathy. Analyses of the five scales in terms of the Pleasure-Arousability-Dominance (PAD) Temperament Model helped explain similarities of the emotional empathy scales with other individual difference measures of prosocial orientation (e.g., affiliation). PAD analyses also explained some paradoxical effects of experimental "empathy arousal" on aggression toward victims. Aggr. Behav. 23:433–445, 1997. © 1997 Wiley-Liss, Inc.     

Beyond subitizing: Is estimation of numerousness a continuous process?

Evidence is presented for the existence of two forms of estimation of numerousness — in addition to subitizing. In the experiment reported here, horizontal rows of 5–8 black dots were subitized, while estimation of 33–89 differed from 10–33 in the structure of intercorrelations between estimates. A three-dimensional space generated by Smallest Space Analysis produced three subsets of intercorrelations among percent absolute errors in estimating dots: 5–8 dots, 10–21 dots, and 33–89 dots.     

A Model‐Based Cluster Analysis of Maternal Emotion Regulation and Relations to Parenting Behavior

In a diverse community sample of mothers (N = 108) and their preschool‐aged children (M_age = 3.50 years), this study conducted person‐oriented analyses of maternal emotion regulation (ER) based on a multimethod assessment incorporating physiological, observational, and self‐report indicators. A model‐based cluster analysis was applied to five indicators of maternal ER: maternal self‐report, observed negative affect in a parent–child interaction, baseline respiratory sinus arrhythmia (RSA), and RSA suppression across two laboratory tasks. Model‐based cluster analyses revealed four maternal ER profiles, including a group of mothers with average ER functioning, characterized by socioeconomic advantage and more positive parenting behavior. A dysregulated cluster demonstrated the greatest challenges with parenting and dyadic interactions. Two clusters of intermediate dysregulation were also identified. Implications for assessment and applications to parenting interventions are discussed.     

Assessment Center Dimensions: Individual differences correlates and meta‐analytic incremental validity

This study provides an investigation of the nomological net for the seven primary assessment center (AC) dimensions identified by Arthur, Day, McNelly, and Eden (Personnel Psychology, 56, 125–154, 2003). In doing so, the authors provide the first robust estimates of the relationships between all primary AC dimensions with cognitive ability and the Big 5 factors of personality. Additionally, intercorrelations between AC dimensions based on sample sizes much larger than those previously available in the meta‐analytic literature are presented. Data were obtained from two large managerial samples (total N=4985). Primary data on AC dimensions, personality, and cognitive ability interrelationships were subsequently integrated with meta‐analytic data to estimate incremental validity for optimally and unit‐weighted AC dimension composites as well as overall AC ratings over psychometric tests of personality and cognitive ability. Results show that unit‐ and optimally weighted composites of construct‐based AC dimensions add incremental validity over tests of personality and cognitive ability, while overall AC ratings (including those obtained using subjective methods of data combination) do not.     

Emotional Intelligence in Selection Contexts: Measurement method,criterion‐related validity,and vulnerability to response distortion

Two studies examined aspects of the validity of self‐report and performance‐based measures of emotional intelligence (EI) relevant to their use in personnel selection. In Study 1, structural equation modeling indicated that a two‐factor model with separate factors for the two types of EI measures fit better than a one‐factor solution. The performance‐based EI factor was more related to cognitive ability (R=.38) than personality (R=.26), whereas the self‐report EI factor was more related to personality (R=.85) than cognitive ability (R=.09). Although the performance‐based EI factor correlated more strongly with job performance (ρ=.24) than did that of the self‐report (ρ=.05), it provided little incremental validity beyond cognitive ability and conscientiousness. In Study 2, participants were asked to complete the measures as if applying for a job, and mean scores were then compared with those of Study 1. Results indicated that self‐report EI measures were more vulnerable to distortion than were the performance‐based measures. Implications for the assessment of EI in personnel selection contexts are discussed.     

Further Evaluation of the Tripartite Structure of Subjective Well‐Being: Evidence From Longitudinal and Experimental Studies

Subjective well‐being (SWB; Diener, 1984) comprises three primary components: life satisfaction (LS), positive affect (PA), and negative affect (NA). Multiple competing conceptualizations of the tripartite structure of SWB have been employed, resulting in widespread ambiguity concerning the definition, operationalization, analysis, and synthesis of SWB‐related findings (Busseri & Sadava, 2011). We report two studies evaluating two predominant structural models (as recently identified by Busseri, 2015): a hierarchical model comprising a higher‐order latent SWB factor with LS, PA, and NA as indicators; and a causal systems model specifying unidirectional effects of PA and NA on LS. A longitudinal study (N = 452; M_age = 18.54; 76.5% female) and a lab‐based experiment (N = 195; M_age = 20.42 years; 87.6% female; 81.5% Caucasian) were undertaken. Structural models were evaluated with respect to (a) associations among SWB components across time (three months, three years in Study 1; one week in Study 2) and (b) the impact of manipulating the individual SWB components (Study 2). A hierarchical structural model was supported in both studies; conflicting evidence was found for the causal systems model. A hierarchical model provides a robust conceptualization for the tripartite structure of SWB.     

Improved set‐size labeling mediates the effect of a counting intervention on children's understanding of cardinality

How does improving children's ability to label set sizes without counting affect the development of understanding of the cardinality principle? It may accelerate development by facilitating subsequent alignment and comparison of the cardinal label for a given set and the last word counted when counting that set (Mix et al., 2012). Alternatively, it may delay development by decreasing the need for a comprehensive abstract principle to understand and label exact numerosities (Piantadosi et al., 2012). In this study, preschoolers (N = 106, M_age = 4;8) were randomly assigned to one of three conditions: (a) count‐and‐label, wherein children spent 6 weeks both counting and labeling sets arranged in canonical patterns like pips on a die; (b) label‐first,wherein children spent the first 3 weeks learning to label the set sizes without counting before spending 3 weeks identical to the count‐and‐label condition; (c) print referencing control. Both counting conditions improved understanding of cardinality through increases in children's ability to label set sizes without counting. In addition to this indirect effect, there was a direct effect of the count‐and‐label condition on progress toward understanding of cardinality. Results highlight the roles of set labeling and equifinality in the development of children's understanding of number concepts.     

Hypnosis versus relaxation: accuracy and confidence in dating international news events

This study compared participants who were administered either a hypnosis (n=50) or a relaxation (n=44) recall priming procedure in terms of the ability to estimate the dates of 20 relatively memorable (‘easy’) vs. less memorable (‘difficult’) international news events. The hypnosis and relaxation groups performed comparably in terms of the accuracy of estimates of when the events occurred, self‐reported confidence in estimates, and the memorability and emotionality of the events that were reported during hypnosis and relaxation. After these initial ratings, participants were informed that ‘at least one’ of their estimates was incorrect, and they were given the opportunity to change their estimates of the date of when one or more of the events occurred. Participants who generated their initial estimates during hypnosis were less likely to change their previous estimates of both easy and difficult events, than were participants in the relaxation condition. The measure of self‐reported confidence and a behavioural measure of willingness to change initial reports were largely dissociated from one another. Copyright © 2005 John Wiley & Sons, Ltd.     

The Influence of Avoidance Temperament and Avoidance‐Based Achievement Goals on Flow

In the present research, we conducted two studies designed to examine the joint influence of avoidance temperament and avoidance‐based achievement goals on the experience of flow on a creativity task. In both a laboratory study (N = 101; M_age = 22.61, SD_age = 4.03; 74.3% female) and a naturalistic study (N = 102; M_age = 16.23, SD_age = 1.13; 48% female), participants high in avoidance temperament were shown to experience greater flow when performance‐avoidance goals were induced; no differences were found in any of the other three achievement goal conditions from the 2 × 2 achievement goal framework. These findings reveal a short‐term benefit for a disposition‐goal match grounded in avoidance motivation, and point to the need for more research on both avoidance‐based matches and the short‐term versus long‐term implications of such matches.     

Ridge structural equation modelling with correlation matrices for ordinal and continuous data

This paper develops a ridge procedure for structural equation modelling (SEM) with ordinal and continuous data by modelling the polychoric/polyserial/product‐moment correlation matrix R . Rather than directly fitting R , the procedure fits a structural model to R _a= R +a I by minimizing the normal distribution‐based discrepancy function, where a > 0. Statistical properties of the parameter estimates are obtained. Four statistics for overall model evaluation are proposed. Empirical results indicate that the ridge procedure for SEM with ordinal data has better convergence rate, smaller bias, smaller mean square error, and better overall model evaluation than the widely used maximum likelihood procedure.     

Perceptions about fleeing religious persecution and entrance to the US

Using four vignettes to study attitudes toward religious persecution, a woman or man aged 22 or 68 came to the US with no supporting documentation. A General Linear Model analysed the 12 items for each vignette. Three items were significant among the vignettes: “All immigration policies and laws should be observed even if it means that M may not be granted permission to stay”; “M’s gender might be an indicator that M wishes to do harm to the US and its citizens” and “M should be deported because s/he entered the country illegally.” Gender and age impact these perceptions.     

Estimating the mean effect size in meta-analysis: Bias,precision, and mean squared error of different weighting methods

Although use of the standardized mean difference in meta-analysis is appealing for several reasons, there are some drawbacks. In this article, we focus on the following problem: that a precision-weighted mean of the observed effect sizes results in a biased estimate of the mean standardized mean difference. This bias is due to the fact that the weight given to an observed effect size depends on this observed effect size. In order to eliminate the bias, Hedges and Olkin (1985) proposed using the mean effect size estimate to calculate the weights. In the article, we propose a third alternative for calculating the weights: using empirical Bayes estimates of the effect sizes. In a simulation study, these three approaches are compared. The mean squared error (MSE) is used as the criterion by which to evaluate the resulting estimates of the mean effect size. For a meta-analytic dataset with a small number of studies, theMSE is usually smallest when the ordinary procedure is used, whereas for a moderate or large number of studies, the procedures yielding the best results are the empirical Bayes procedure and the procedure of Hedges and Olkin, respectively.     

Proneness to hallucinations and delusions in a non‐clinical sample: Exploring associations with metacognition and negative affect

Commonly, individuals prone to hallucinations and delusions hold dysfunctional metacognitive beliefs and report higher levels of negative affect, yet, these associations have not been clearly investigated in non‐clinical samples due to the failure to control for high intercorrelations between variables. The aim of the current study was to investigate how hallucination and delusion proneness are associated with dysfunctional metacognitions and negative affect. A cross‐sectional sample of 715 students free from psychiatric diagnoses (M_age = 28.1 years, SD = 10.9, range 18–65) completed the Launay‐Slade Hallucination Scale (LSHS‐R); Peters et al. Delusion Inventory (PDI‐21); Depression, Anxiety, and Stress Scale (DASS‐21); and the Metacognition Questionnaire (MCQ‐30). Findings that participants who were prone to both hallucinations and delusions reported elevated levels of negative affect support the need for targeted mental health treatment for individuals who experience psychological distress related to their hallucinatory and delusional experiences. While metacognition beliefs of need to control thoughts and cognitive self‐consciousness, along with the anxiety and stress DASS‐21 subscales appeared as significant cross‐sectional predictors of proneness to hallucinations and delusions, only metacognitions demonstrated any notable predictive value for delusion proneness. This finding questions the role of metacognitions in determining hallucination and delusion proneness in non‐clinical samples.
