Considering too few alternatives: The mental model theory of extensional reasoning

When solving a simple probabilistic problem, people tend to build an incomplete mental representation. We observe this pattern in responses to probabilistic problems over a set of premises using the conjunction, disjunction, and conditional propositional connectives. The mental model theory of extensional reasoning explains this bias towards underestimating the number of possibilities: In reckoning with different interpretations of the premises (logical rules, mental model theoretical, and, specific to conditional premises, conjunction and biconditional interpretation) the mental model theory accounts for the majority of observations. Different interpretations of a premise result in a build-up of mental models that are often incomplete. These mental models are processed using either an extensional strategy relying on proportions amongst models, or a conflict monitoring strategy. The consequence of considering too few possibilities is an erroneous probability estimate akin to that faced by decision makers who fail to generate and consider all alternatives, a characteristic of bounded rationality. We compare our results to the results published by Johnson-Laird, Legrenzi, Girotto, Legrenzi, and Caverni [Johnson-Laird, P., Legrenzi, P., Girotto, V., Legrenzi, M., &; Caverni, J.

Quality of Life in the U.S. Navy: Impact on Performance and Career Continuance

Previous research has shown the importance of quality of life (QOL) for critical organizational outcomes such as the retention of U.S. Navy personnel (Wilcove, Schwerin, &; Wolosin, 2003 Wilcove, G., Schwerin, M. and Wolosin, D. 2003. An exploratory model of quality of life in the U.S. Navy.. Military Psychology, 15(2): 133–152. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) and Marines (Hindelang, Schwerin, &; Farmer, 2004 Hindelang, R. L., Schwerin, M. J. and Farmer, W. L. 2004. Quality of life (QOL) in the U.S. Marine Corps: The validation of a QOL model for predicting reenlistment intentions.. Military Psychology, 16(2): 115–134. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). These studies employed a life domains approach addressing a full range of work and non-work life needs as well as specific aspects of each life domain. In contrast, most other research exploring outcomes critical to military organizations focused only on work life needs of personnel (e.g., job satisfaction, organizational commitment, command climate). This study extends previous research by (a) including both performance and career-continuance plans of personnel as outcomes of interest, (b) exploring the contribution of an additional life need—spiritual well-being—to the measurement of QOL, and (c) examining changes in perceptions of QOL over time between 1999 and 2002 among U.S. Navy personnel. Implications of findings to military personnel, families, and manpower and personnel policy as well as future directions for research are discussed.     

Predictors of Self-Reported Prospective and Retrospective Memory in a Population-Based Sample of Older Adults

In this article, the authors examined predictors of self-reported everyday memory failures using the Prospective and Retrospective Questionnaire (PRMQ; Smith, Della Sala, Logie, &; Maylor, 2000 Smith, G. V., Della Sala, S., Logie, R. H. and Maylor, E. A. M. 2000. Prospective and retrospective memory in normal ageing and dementia: A questionnaire study. Memory, 8: 311–321. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) in a population-based sample of older adults (age range = 60–90 years; N = 250). The results showed that a higher frequency of reported failures was associated with lower scores on the personality dimension of self-directedness as assessed by the Temperament and Character Inventory (TCI; Cloninger, Dragan, Svrakic, &; Przybeck, 1993 Cloninger, R. C., Dragan, M. S., Svrakic, D. M. and Przybeck, T. R. 1993. A psychobiological model of temperament and character. Archives of General Psychiatry, 50: 975–990. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and more depressive symptoms on the Center for Epidemiological Studies Depression Scale (CES-D; Radloff, 1977 Radloff, L. S. 1977. The CES-D scale: A self-report depression scale for research in the general population. Applied Psychological Measurement, 1: 385–401. [Crossref], [Web of Science ®] , [Google Scholar]). However, PRMQ scores showed no relationships with objective memory ability, as reflected by a series of retrospective memory measures and a measure of prospective memory. Neither were the PRMQ scales associated with general cognitive functioning as assessed by the Mini-Mental State Examination (MMSE; Folstein, Folstein, &; McHugh, 1977). Taken together, the results indicate that within the older population, self-reported memory as assessed by the PRMQ may reflect mood-state and personality factors rather than individual differences in memory and cognitive ability.     

Multi-Iteration Usability Testing of the U.S. Navy's Performance Management System

The U.S. Navy has undertaken the second of two iterations of usability testing for the Navy's Human Performance Feedback and Development (HPFD) and ePerformance system. This second of two iterations included 34 officer and enlisted supervisors and nonsupervisors in usability testing conducted at three Navy locations—Naval Meteorology and Oceanographic Center (NAVMETOCCEN) Norfolk in Norfolk, Virginia; USS HOWARD (DDG 83) in San Diego, California; and the Bureau of Naval Personnel (BUPERS) in Arlington, Virginia. Each participant completed a usability test scenario in addition to pretest and posttest surveys designed to obtain Navy personnel's subjective impressions of the HPFD and ePerformance systems. Results from analyses comparing data from Iteration 1 (reported in Schwerin, Dean, Robbins, Bourne, &; Reed, 2006 Schwerin, M. J., Dean, E., Robbins, K. M., Bourne, M. J. and Reed, L. 2006. Subjective and objective results of usability testing for the U.S. Navy's Performance Management System.. Military Psychology, 18(3): 227–245. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) and Iteration 2 (reported in Dean, Aspinwall, Schwerin, &; Kendrick, 2006 Dean, E., Aspinwall, K. R., Schwerin, M. J. and Kendrick, D. 2006. Usability results from Human Performance Feedback and Development (HPFD) and ePerformance system users (Tech. Rep. No. 1)., Research Triangle Park, NC: RTI International. [Crossref] , [Google Scholar]) show an overall reduction in user burden (e.g., fewer errors and less time to complete usability tasks) and increased user satisfaction (e.g., more satisfied with the professionalism, efficiency, and overall effectiveness). These findings indicate that the Navy HPFD and ePerformance systems are easier to use but, more generally, results support the value and effectiveness of usability in human systems integration (HSI) and usability testing. Recommendations for system refinement, policy development, and implementation planning are discussed.     

Processing of musical structure by high-functioning adolescents with autism spectrum disorders

Enhanced pitch perception and memory have been cited as evidence of a local processing bias in autism spectrum disorders (ASD). This bias is argued to account for enhanced perceptual functioning (Mottron &; Burack, 2001 Mottron, L. and Burack, J. A. 2001. “Enhanced perceptual functioning in the development of autism”. In The development of autism: Perspectives from theory to research, Edited by: Burack, J. A., Charman, T., Yirmiya, N. and Zelazo, P. R. 131–147. Mahwah, NJ: Lawrence Erlbaum.  [Google Scholar]; Mottron, Dawson, Soulières, Hubert, &; Burack, 2006 Mottron, L., Dawson, M., Soulières, I., Hubert, B. and Burack, J. 2006. Enhanced perceptual functioning in autism: An update, and eight principles of autistic perception. Journal of Autism and Developmental Disorders, 36(1): 27–43. doi:10.1007/s10803-005-0040-7[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and central coherence theories of ASD (Frith, 1989 Frith, U. 1989. Autism: Explaining the enigma, Oxford: United Kingdom: Blackwell.  [Google Scholar]; Happé &; Frith, 2006 Happé, F. and Frith, U. 2006. The weak coherence account: Detail-focused cognitive style in autism spectrum disorders. Journal of Autism and Developmental Disorders, 36(1): 5–25. doi:10.1007/s10803-005-0039-0[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). A local processing bias confers a different cognitive style to individuals with ASD (Happé, 1999 Happé, F. 1999. Autism: Cognitive deficit or cognitive style?. Trends in Cognitive Sciences, 3(6): 216–222. doi:10.1016/S1364-6613(99)01318-2[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), which accounts in part for their good visuospatial and visuoconstructive skills. Here, we present analogues in the auditory domain, audiotemporal or audioconstructive processing, which we assess using a novel experimental task: a musical puzzle. This task evaluates the ability of individuals with ASD to process temporal sequences of musical events as well as various elements of musical structure and thus indexes their ability to employ a global processing style. Musical structures created and replicated by children and adolescents with ASD (10–19 years old) and typically developing children and adolescents (7–17 years old) were found to be similar in global coherence. Presenting a musical template for reference increased accuracy equally for both groups, with performance associated to performance IQ and short-term auditory memory. The overall pattern of performance was similar for both groups; some puzzles were easier than others and this was the case for both groups. Task performance was further found to be correlated with the ability to perceive musical emotions, more so for typically developing participants. Findings are discussed in light of the empathizing-systemizing theory of ASD (Baron-Cohen, 2009 Baron-Cohen, S. 2009. Autism: The Empathizing-Systemizing (E-S) Theory. Annals of the New York Academy of Sciences, 1156: 68–80. doi:10.1111/j.1749-6632.2009.04467.x[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and the importance of describing the strengths of individuals with ASD (Happé, 1999 Happé, F. 1999.

The Effect of the Accountability Variables of Responsibility,Openness, and Answerability on Authentic Leadership

One salient aspect of authentic leadership is the possibility that it can be developed (Walumbwa, Avolio, Gardner, Wernsing, &; Peterson, 2008 Walumbwa, F. O., Avolio, B. J., Gardner, W. L., Wernsing, T. S., &; Peterson, S. J. (2008). Authentic leadership: Development and validation of a theory-based measure. Journal of Management, 34(1), 89–126. doi:10.1177/0149206307308913[Crossref], [Web of Science ®] , [Google Scholar]). However, the relative paucity of research on authentic leadership as a dependent variable needs to be addressed. The purpose of this cross-sectional quantitative study is to examine the three factors of accountability: (a) responsibility, (b) openness, and (c) answerability (Wood &; Winston, 2007 Wood, J. A., &; Winston, B. E. (2007). Development of three scales to measure leader accountability. Leadership &; Organization Development Journal, 28(2), 167–185. doi:10.1108/01437730710726859[Crossref] , [Google Scholar]) as antecedents to authentic leadership. Using survey results from a sample of full-time employees at six faith-based institutions of higher education in the United States, a predictive relationship was investigated through hierarchical regression analysis. The results indicated that the variables of responsibility, openness, and answerability predict the perception of authentic leadership.     

Neuropsychological Behavioral Inhibition System (BIS) and Behavioral Approach System (BAS) Assessment: A Shortened Sensitivity to Punishment and Sensitivity to Reward Questionnaire Version (SPSRQ–20)

This research was designed to investigate the items and factor structure of the Sensitivity to Punishment and Sensitivity to Reward Questionnaire (SPSRQ) proposed by Torrubia, Avila, Moltó, and Caseras (2001 Spielberger, C. D., Gorsuch, R. L. and Lushene, R. E. 1970. Manual for the State-Trait Anxiety Inventory., Palo Alto, CA: Consulting Psychologists Press.  [Google Scholar]), as a measure of the behavioral inhibition system and behavioral activation system in Gray's reinforcement sensitivity theory. Recent studies that analyzed this instrument by exploratory and confirmatory factor analysis suggest the need for structural refinement. The Spanish version of the SPSRQ was analyzed by exploratory and confirmatory procedures in calibration (n = 2,102) and validation (n = 746) independent samples. In addition, convergent and discriminant validity was evaluated with the Zuckerman–Kuhlman Personality Questionnaire (Zuckerman, Kuhlman, Teta, Joireman, &; Kraft, 1993 Torrubia, R. and Tobeña, A. 1984. A scale for the assessment of susceptibility to punishment as a measure of anxiety: Preliminary results. Personality and Individual Differences, 5: 371–375. [Crossref], [Web of Science ®] , [Google Scholar]), the Impulsiveness, Venturesomeness and Empathy Inventory (S. B. G. Eysenck, Pearson, Easting, &; Allsopp, 1985 Eysenck, S. B. G., Pearson, P. R., Easting, G. and Allsopp, F. J. 1985. Age norms for impulsiveness, venturesomeness and empathy in adults. Personality and Individual Differences, 6: 613–619. [Crossref], [Web of Science ®] , [Google Scholar]) the Neuroticism, Extraversion and Openness Five Factor Inventory (Costa &; McCrae, 1992 Costa, P. T. and McCrae, R. R. 1992. NEO–PI–R professional manual: Revised NEO Personality Inventory (NEO–PI–R) and NEO Five Factor Inventory (NEO–FFI), Odessa, FL: Psychological Assessment Resources.  [Google Scholar]), and the Barratt Impulsiveness Scales (Barratt, 1985 Ball, S. and Zuckerman, M. 1990. Sensation seeking, Eysenck's personality dimensions and reinforcement sensitivity in concept formation. Personality and Individual Differences, 11: 343–355. [Crossref], [Web of Science ®] , [Google Scholar]). Results showed the robustness of a 20-item structure of the SPSRQ, with satisfactory fit adjustment, validity, and reliability. The findings are discussed in terms of the better functioning and sound psychometric properties of the SPSRQ 20-item version for Gray's personality theory.     

Mind Perception and Individual Differences: A Replication and Extension

Mind perception involves attributing higher functional abilities to others (e.g., saying a dog feels pain). The relationships between mind perception and psychopathology—autism, psychopathy, and schizotypy—have been revealed by K. Gray, Jenkins, Heberlein, and Wegner (2011 Gray, K., Jenkins, A. C., Heberlein, A. S., &; Wegner, D. M. (2011). Distortions of mind perception in psychopathology. Proceedings of the National Academy of Sciences of the United States of America, 108, 477–479. doi:10.1073/pnas.1015493108[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]); however, mind perception has yet to be correlated with personality. Participants (N = 180) completed measures of personality, psychopathology, and mind perception. The psychopathology results were consistent with Gray et al. (2011 Gray, K., Jenkins, A. C., Heberlein, A. S., &; Wegner, D. M. (2011). Distortions of mind perception in psychopathology. Proceedings of the National Academy of Sciences of the United States of America, 108, 477–479. doi:10.1073/pnas.1015493108[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). The Big Five captured mind perception virtually as much as the three psychopathologies captured mind perception. Mind perception is not solely relevant to psychopathology; it is also relevant to everyday personality.     

Implicit and Explicit Sexual Motives as Related,But Distinct Characteristics

A measure of implicit sexual motives—the implicit AMORE—was constructed employing the Affect Misattribution Procedure (Payne, Cheng, Govorun, &; Stewart, 2005 Payne, B. K., Cheng, C. M., Govorun, O., &; Stewart, B. D. (2005). An inkblot for attitudes: Affect misattribution as implcit measurement. Journal of Personality and Social Psychology, 89, 277–293. doi:10.1037/0022-3514.89.3.277[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Subscales paralleled the 8 dimensions identified previously by the self-report measure of sexual motives, the explicit AMORE (Hill &; Preston, 1996 Hill, C. A., &; Preston, L. K. (1996). Individual differences in the experience of sexual motivation: Theory and measurement of dispositional sexual motives. Journal of Sex Research, 33, 27–45. doi:10.1080/00224499609551812[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). Confirmatory factor analyses supported the proposed 8-factor model in slightly revised form, which was confirmed based on a second independent set of participants. Consistent with hypotheses, the implicit scales correlated with nonconscious erotica-viewing behavior for women in a laboratory setting. In contrast to explicit scales, implicit scales were unrelated to self-report ratings of likely sexual behavior. Finally, self-reports of aspects of sexual behavior were generally associated with the measures of implicit motives independently of corresponding explicit motives for both women and men. The results support the conception of implicit sexual motives as related, but distinct from explicit sexual motives.     

Nonpathological and Pathological Narcissism: Which Self-Reported Characteristics Are Most Problematic in Adolescents?

Prior research indicates that dimensions of adolescent narcissism differ in their associations with indicators of positive and negative psychological functioning (e.g., Barry, Frick, Adler, &; Grafeman, 2007 Barry, C. T., Frick, P. J., Adler, K. K. and Grafeman, S. J. 2007. The predictive utility of narcissism among children and adolescents: Evidence for a distinction between adaptive and maladaptive narcissism. Journal of Child and Family Studies, 16: 508–521. [Crossref] , [Google Scholar]; Barry &; Wallace, 2010 Barry, C. T. and Wallace, M. T. 2010. Current considerations in the assessment of youth narcissism: Indicators of pathological and normative development. Journal of Psychopathology and Behavioral Assessment, 32: 479–489. [Crossref], [Web of Science ®] , [Google Scholar]). This study investigated correlates of 2 empirically derived factors of adolescent narcissism (i.e., pathological and nonpathological narcissism) from 2 measures thought to differ based on their inclusion of pathological versus nonpathological content. In a sample of 188 at-risk adolescents ages 16 to 18, pathological narcissism was associated with various indicators of maladjustment, including aggression, low self-esteem, internalizing problems, and poor perceived interpersonal relationships. On the other hand, nonpathological narcissism was positively associated with self-esteem and aggression but negatively associated with internalizing problems. The implications for the conceptualization of adolescent narcissism are discussed.     

Sample Sizes for Two-Group Second-Order Latent Growth Curve Models

Second-order latent growth curve models (S. C. Duncan &; Duncan, 1996 Duncan, S. C. and Duncan, T. E. 1996. A multivariate growth curve analysis of adolescent substance use.. Structural Equation Modeling, 3: 323–347. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]; McArdle, 1988 McArdle, J. J. 1988. “Dynamic but structural equation modeling of repeated measures data.”. In Handbook of multivariate experimental psychology, , 2nd ed. Edited by: Cattell, R. B. and Nesselroade, J. 564–614. New York: Plenum.. [Crossref] , [Google Scholar]) can be used to study group differences in change in latent constructs. We give exact formulas for the covariance matrix of the parameter estimates and an algebraic expression for the estimation of slope differences. Formulas for calculations of the required sample size are presented, illustrated, and discussed. They are checked by Monte Carlo simulations in Mplus and also by Satorra and Saris's (1985) Satorra, A. and Saris, W. E. 1985. The power of the likelihood ratio test in covariance structure analysis.. Psychometrika, 50: 83–90. [Crossref], [Web of Science ®] , [Google Scholar] power approximation techniques for small and medium effect sizes (Cohen, 1988 Cohen, J. 1988. Statistical power analysis for the behavioral sciences. Hillsdale, NJ: Erlbaum..  [Google Scholar]). Results are similar across methods. Not surprisingly, sample sizes decrease with effect sizes, indicator reliabilities, number of indicators, frequency of observation, and duration of study. The relative importance of these factors is also discussed, alone and in combination. The use of the sample size formula is illustrated using a modification of empirical results from Stoel, Peetsma, and Roeleveld (2003) Stoel, R. D., Peetsma, T. T. and Roeleveld, J. 2003. Relations between the development of school investment, self-confidence, and language achievement in elementary education: A multivariate latent growth curve approach.. Learning and Individual Differences, 13: 313–333. [Crossref], [Web of Science ®] , [Google Scholar].     

The Rediscovery of Bifactor Measurement Models

Bifactor latent structures were introduced over 70 years ago, but only recently has bifactor modeling been rediscovered as an effective approach to modeling construct-relevant multidimensionality in a set of ordered categorical item responses. I begin by describing the Schmid-Leiman bifactor procedure (Schmid &; Leiman, 1957 Schmid, J. 1957. The comparability of the bi-factor and second-order factor patterns. Journal of Experimental Education, 25: 249–253. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) and highlight its relations with correlated-factors and second-order exploratory factor models. After describing limitations of the Schmid-Leiman, 2 newer methods of exploratory bifactor modeling are considered, namely, analytic bifactor (Jennrich &; Bentler, 2011 Jennrich, R. I. and Bentler, P. M. 2011. Exploratory bi-factor analysis. Psychometrika, 76: 537–549. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) and target bifactor rotations (Reise, Moore, &; Maydeu-Olivares, 2011 Reise, S. P., Moore, T. M. and Maydeu-Olivares, A. 2011. Targeted bifactor rotations and assessing the impact of model violations on the parameters of unidimensional and bifactor models. Educational and Psychological Measurement, 71: 684–711. [Crossref], [Web of Science ®] , [Google Scholar]). Then I discuss limited- and full-information estimation approaches to confirmatory bifactor models that have emerged from the item response theory and factor analysis traditions, respectively. Comparison of the confirmatory bifactor model to alternative nested confirmatory models and establishing parameter invariance for the general factor also are discussed. Finally, important applications of bifactor models are reviewed. These applications demonstrate that bifactor modeling potentially provides a solid foundation for conceptualizing psychological constructs, constructing measures, and evaluating a measure's psychometric properties. However, some applications of the bifactor model may be limited due to its restrictive assumptions.     

Executive function and memory in children with Fetal Alcohol Spectrum Disorder

A complex relation exists between memory and executive functioning (EF), particularly when learning and recalling multifaceted or extensive information (Moscovitch &; Winocur, 2002 Moscovitch, M. and Winocur, G. 2002. “The frontal cortex and working with memory”. In Principles of frontal lobe functioning, Edited by: Stuss, D. T. and Knight, R. T. 188–209. New York, NY: Oxford University Press.  [Google Scholar]). A common instrument for evaluating this relationship is the Rey-Osterrieth Complex Figure (ROCF; Rey, 1941 Rey, A. 1941. L'examen psychologique dans le cas d'encephalopathie traumatique [Psychological examination of traumatic encephalopathy]. Archives de Psychologie, 28: 286–340.  [Google Scholar]; Osterrieth, 1944 Osterrieth, P. A. 1944. Le test de copie d'une figure complexe: Contribution à l’étude de la perception et de la mémoire [The test of copying a complex figure: A contribution to the study of perception and memory]. Archives de Psychologie, 30: 286–350.  [Google Scholar]). The ROCF has proved particularly useful in pediatric research; however, little research has been conducted among children with Fetal Alcohol Spectrum Disorders (FASD).

Seventy children (35 FASD, 35 control), aged 6 to 12 years, were tested using the ROCF. All participants with FASD had received a diagnosis according to the Canadian guidelines for FASD (Chudley et al., 2005 Chudley, A. E., Conry, J., Cook, J. L., Loock, C., Rosales, T. and LeBlanc, N. 2005. Fetal alcohol spectrum disorder: Canadian guidelines for diagnosis. The Canadian Medical Association Journal, 172: 1–21. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) using the 4-digit diagnostic code (Astley, 2004 Astley, S. J. 2004. Diagnostic guide for fetal alcohol spectrum disorders: The 4-digit diagnostic code, 3rd, Seattle, WA: University of Washington.  [Google Scholar]). Significant group differences were revealed with children with FASD demonstrating substantial difficulties in organization, accuracy, and memory. Among children with FASD, a distinctive profile emerged, lending support to the argument that children with FASD experience deficits in EF and memory throughout their development. Information from the present study will not only help to improve understanding of functioning in this population but also provide insight into how to deal with EF and memory deficits in terms of testing, treatment, and intervention.     

CBT for Children and Adolescents With High-Functioning Autism Spectrum Disorders,edited by A. Scarpa,S. Williams White, & T. Attwood

ABSTRACT

Parent-Child Interaction Therapy (PCIT) is a manualized behavioral intervention originally developed by Eyberg (1988 Eyberg, S. (1988). Parent-child interaction therapy: Integration of traditional and behavioral concerns. Child &; Family Behavior Therapy, 10(1), 33–46. doi:10.1300/j019v10n01_04[Taylor &; Francis Online] , [Google Scholar]) to address disruptive behaviors in young children. Although previous research findings support the contention that components of PCIT would positively impact communication, behavior, and adaptive skills (Howard, Sparkman, Cohen, Green, &; Stanislaw, 2005; Lovaas, 1987 Lovaas, O. I. (1987). Behavioral treatment and normal educational and intellectual functioning in young autistic children. Journal of Consulting and Clinical Psychology, 55(1), 3–9. doi:10.1037/0022-006x.55.1.3[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]; Remington et al., 2007 Remington, B., Hastings, R. P., Kovshoff, H., Degli Espinosa, F., Jahr, E., Brown, T., &; Ward, N. (2007). Early intensive behavioral intervention: Outcomes for children with autism and their parents after two years. American Journal on Mental Retardation, 112(6), 418–438. doi:10.1352/0895-8017(2007)112[418:eibiof]2.0.co;2[Crossref], [PubMed] , [Google Scholar]) in children with developmental disabilities, few studies are shown in the literature. In a modified version of PCIT, caregivers completed two phases of intervention with their child diagnosed with Autism Spectrum Disorder (ASD). During the Child-Directed Interaction (CDI) phase, caregivers were taught to conduct mand training, follow-their child’s lead, provide attention for their child’s positive behaviors, and ignore their child’s negative behaviors. During the Parent-Directed Interaction (PDI) phase, caregivers were taught to give effective commands and follow through with demands. The goal of the current study was to determine whether children’s production of vocalizations increased after participation in a modified PCIT program. Data from two participants diagnosed with autism were included in the study. Outcomes of these two case studies show that both children displayed an increase in the total number of vocalizations emitted in the posttreatment observation relative to baseline. Additionally, caregivers of both participants displayed an increased number of positive behaviors in the posttreatment observation relative to baseline.     

Mutual Suppression: Comment on Paulhus et al. (2004)

Paulhus, Robins, Trzesniewski, and Tracy (Multivariate Behavioral Research, 2004 Paulhus, D. L., Robins, R. W., Trzesniewski, K. H. and Tracy, J. L. 2004. Two replicable suppressor situations in personality research. Multivariate Behavioral Research, 39: 303–328. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar], 39, 305–328) suggested that the three types of two-predictor suppression situations—classical suppression, cooperative suppression, and net suppression—-can all be considered special cases of mutual suppression, in that the magnitude of each of the two standardized partial regression coefficients exceeds the magnitude of its corresponding standardized bivariate regression coefficient. Classical suppression and cooperative suppression can be considered mutual suppression, but net suppression cannot. Hypothetical and empirical examples of net suppression in which the magnitude of the standardized partial regression coefficient for the suppressor variable is greater than, equal to, and less than the magnitude of its standardized bivariate regression coefficient are provided. The empirical examples were drawn from the social psychology literature relating psychological well-being outcomes to life aspirations.     

Correcting Overestimated Effect Size Estimates in Multiple Trials

In a simulation study, Brand, Bradley, Best, and Stoica (2011 Brand, A., Bradley, M. T., Best, L. A. and Stoica, G. 2011. Multiple trials may yield exaggerated effect size estimates. The Journal of General Psychology, 138: 1–11. [Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]) have shown that Cohen's d is notably overestimated if computed for data aggregated over multiple trials. Although the phenomenon is highly important for studies and meta-analyses of studies structurally similar to the simulated scenario, the authors do not comprehensively address how the problem could be handled. In this comment, we first suggest a corrective term d ^′ _c that includes the number and correlation of trials. Next, the results of a simulation study provide evidence that the proposed d_c′ results in a more precise estimation of trial-level effects. We conclude that, in practice, d ^′ _c together with plausible estimates of inter-trial correlation will produce a more precise effect size range compared to that suggested by Brand and colleagues (2011 Brand, A., Bradley, M. T., Best, L. A. and Stoica, G. 2011. Multiple trials may yield exaggerated effect size estimates. The Journal of General Psychology, 138: 1–11.
