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.

Examining the Construct Validity of the MMPI–2–RF Interpersonal Functioning Scales Using the Computerized Adaptive Test of Personality Disorder as a Comparative Framework

This study aimed to examine the construct validity of the Minnesota Multiphasic Personality Inventory–2 Restructured Form (MMPI–2–RF) interpersonal functioning scales (Ben-Porath &; Tellegen, 2008/2011 Ben-Porath, Y. S., &; Tellegen, A. (2011). MMPI–2–RF (Minnesota Multiphasic Personality Inventory–2 Restructured Form) manual for administration, scoring, and interpretation. Minneapolis: University of Minnesota Press. (Original work published 2008) [Google Scholar]) using as a criterion measure the Computerized Adaptive Test of Personality Disorder–Static Form (CAT–PD–SF; Simms et al., 2011 Simms, L. J., Goldberg, L. R., Roberts, J. E., Watson, D., Welte, J., &; Rotterman, J. H. (2011). Computerized adaptive assessment of personality disorder: Introducing the CAT–PD project. Journal of Personality Assessment, 93, 380–389.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). Participants were college students (n = 98) recruited through the university subject pool. A series of a priori hypotheses were developed for each of the 6 interpersonal functioning scales of the MMPI–2–RF, expressed as predicted correlations with construct-relevant CAT–PD–SF scales. Of the 27 specific predictions, 21 were supported by substantial (≥ |.30|) correlations. The MMPI–2–RF Family Problems scale (FML) demonstrated the strongest correlations with CAT–PD–SF scales Anhedonia and Mistrust; Cynicism (RC3) was most highly correlated with Mistrust and Norm Violation; Interpersonal Passivity (IPP) was most highly correlated with Domineering and Rudeness; Social Avoidance (SAV) was most highly correlated with Social Withdrawal and Anhedonia; Shyness (SHY) was most highly correlated with Social Withdrawal and Anxioiusness; and Disaffiliativeness (DSF) was most highly correlated with Emotional Detachment and Mistrust. Results are largely consistent with hypotheses suggesting support for both models of constructs relevant to interpersonal functioning. Future research designed to more precisely differentiate Social Avoidance (SAV) and Shyness (SHY) is suggested.     

The Age of Imagination

Galileo once said that one cannot understand the universe without comprehending its language: mathematics. Unfortunately, most individuals will approach physical sciences with dread, due in part to the difficulty with speaking the language of the universe, and for this reason may fail to perceive its breathtaking beauty. When we look deeper than the letter of reason, we encounter a flow of imagination that appears to be integral to the cosmos. The Enlightenment of the 18th century was an Age of Reason that deeply shaped our modern society. By following the movement of ideas from classical physics to quantum mechanics, passing by chaos theory and Einstein’s special and general relativity, it is argued that a new Enlightenment might be in sight, an Age of Imagination, wherein the creatures that we are will consciously re-enter the flow of imagination. This exploration concerns classical physics and its repression of imagination; the difficult emergence of deterministic chaos is viewed as a return of what was left behind, so to speak: the shadow of reason.

The one-after-another is a bearable prelude to the deeper knowledge of the side-by-side, for this is an incomparably more difficult problem.—C. G. Jung (1970 Jung, C.G. (1970). The collected works of C. G. Jung, Vol. 14: Mysterium coniunctionis (R. F. C. Hull, Trans.; H. Read, M. Fordham, G. Adler, &; W. McGuire, eds.). Bollingen Series XX. Princeton, NJ: Princeton University Press. [Google Scholar], par. 206)     

Three decades of lay epistemics: The why,how, and who of knowledge formation

A conceptual integration and review are presented of three separate research programmes informed by the theory of lay epistemics (Kruglanski, 1989 Kruglanski, A. W. 1989. Lay epistemics and human knowledge: Cognitive and motivational bases, New York: Plenum. [Crossref] , [Google Scholar]). They respectively address the “why”, “how”, and “who” questions about human knowledge formation. The “why” question is treated in work on the need for cognitive closure that propels epistemic behaviour and affects individual, interpersonal, and group phenomena. The “how” question is addressed in work on the unimodel (Kruglanski, Pierro, Mannetti, Erb, & Chun, 2007 Kruglanski, A. W., Pierro, A., Mannetti, L., Erb, H. P. and Chun, W. Y. 2007. “On the parameters of social judgement”. In Advances in experimental social psychology, Edited by: Zanna, M. P. Vol. 39, 255–296. New York: Academic Press.  [Google Scholar]) depicting the process of drawing conclusions from the “information given”. The “who” question is addressed in work on “epistemic authority” highlighting the centrality of source effects (including oneself as a source) in human epistemic behaviour. These separate research paradigms explore facets of epistemic behaviour that jointly produce human knowledge, of essential significance to people's’ individual and social functioning.     

A closer look at moral dilemmas: Latent dimensions of morality and the difference between trolley and footbridge dilemmas

Although a distinction between moral-personal and moral-impersonal dilemmas (Greene, Sommerville, Nystrom, Darley, & Cohen, 2001 Greene, J. D., Sommerville, R. B., Nystrom, L. E., Darley, J. M. and Cohen, J. D. 2001. An fMRI investigation of emotional engagement in moral judgement. Science, 293: 2105–2108. doi:10.1126/science.1062872.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) has been widely accepted as an explanation for a difference between the trolley and footbridge dilemmas (Thomson, 1985 Thomson, J. J. 1985. “The trolley problem”. In Ethics: Problems and principles, Edited by: Fischer, J. M. and Ravizza, M. Fort Worth, TX: Harcourt Brace Jovanovich.  [Google Scholar]), its psychometric properties remain a mystery. In this study 219 participants completed 62 moral dilemma tasks used in Greene et al. (2001 Greene, J. D., Sommerville, R. B., Nystrom, L. E., Darley, J. M. and Cohen, J. D. 2001. An fMRI investigation of emotional engagement in moral judgement. Science, 293: 2105–2108. doi:10.1126/science.1062872.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]), and the correlation structure among the dilemmas was analysed through factor analysis and structural equation modelling. Findings suggest that, first, moral-personal dilemmas are composed of one factor, indicating that the assumption in Greene et al. (2001 Greene, J. D., Sommerville, R. B., Nystrom, L. E., Darley, J. M. and Cohen, J. D. 2001. An fMRI investigation of emotional engagement in moral judgement. Science, 293: 2105–2108. doi:10.1126/science.1062872.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) was supported. Second, moral-impersonal dilemmas are explained by two factors that reflect procedural and consequential aspects of decision making. Third, the trolley and footbridge dilemmas fall under the same factor category; therefore the difference between the two dilemmas cannot be attributed to emotional involvement. Additionally, the results of the structural equation modelling suggest that they differ in the engagement of rational processing.     

The Effect of Response Bias on the Personality Inventory for DSM–5 (PID–5)

Valid self-report assessment of psychopathology relies on accurate and credible responses to test questions. There are some individuals who, in certain assessment contexts, cannot or choose not to answer in a manner typically representative of their traits or symptoms. This is referred to, most broadly, as test response bias. In this investigation, we explore the effect of response bias on the Personality Inventory for DSM–5 (PID–5; Krueger, Derringer, Markon, Watson, & Skodol, 2013 Krueger, R. F., Derringer, J., Markon, K. E., Watson, D., & Skodol, A. E. (2013). The Personality Inventory for DSM–5 (PID–5)–Adult (Full version). Washington, DC: American Psychiatric Association. [Google Scholar]), a self-report instrument designed to assess the pathological personality traits used to inform diagnosis of the personality disorders in Section III of DSM–5. A set of Minnesota Multiphasic Personality Inventory Restructured Form (MMPI–2–RF; Ben-Porath & Tellegen, 2008 Tellegen, A., & Ben-Porath, Y. S (2008). MMPI–2–RF technical manual. Minneapolis: University of Minnesota Press. [Google Scholar]/2011 Ben-Porath, Y. S., & Tellegen, A. (2011). MMPI–2–RF manual for administration, scoring, and interpretation. Minneapolis: University of Minnesota Press. (Original work published 2008) [Google Scholar]) validity scales, which are used to assess and identify response bias, were employed to identify individuals who engaged in either noncredible overreporting (OR) or underreporting (UR), or who were deemed to be reporting or responding to the items in a “credible” manner—credible responding (CR). A total of 2,022 research participants (1,587 students, 435 psychiatric patients) completed the MMPI–2–RF and PID–5; following protocol screening, these participants were classified into OR, UR, or CR response groups based on MMPI–2–RF validity scale scores. Groups of students and patients in the OR group scored significantly higher on the PID–5 than those students and patients in the CR group, whereas those in the UR group scored significantly lower than those in the CR group. Although future research is needed to explore the effects of response bias on the PID–5, results from this investigation provide initial evidence suggesting that response bias influences scale elevations on this instrument.     

Knowledge-How and Epistemic Value

A conspicuous oversight in recent debates about the vexed problem of the value of knowledge has been the value of knowledge-how. This would not be surprising if knowledge-how were, as Gilbert Ryle [1945, 1949 Ryle, Gilbert 1949. The Concept of Mind, London: Hutchinson's University Library.[Crossref] , [Google Scholar]] famously thought, fundamentally different from knowledge-that. However, reductive intellectualists [e.g. Stanley and Williamson 2001 Ryle, Gilbert 1949. The Concept of Mind, London: Hutchinson's University Library.[Crossref] , [Google Scholar]; Brogaard 2008, 2009 Brogaard, Berit 2009. What Mary Did Yesterday: Reflections on Knowledge-Wh, Philosophy and Phenomenological Research 78/2: 439–67.[Crossref], [Web of Science ®] , [Google Scholar], 2011 Brogaard, Berit 2011. Knowledge-How: A Unified Account, in Knowing How: Essays on Knowledge, Mind, and Action, ed. John Bengson and Marc A. Moffett, New York: Oxford University Press: 136–60. [Google Scholar]; Stanley 2011a Stanley, Jason 2011a. Knowing (How), Noûs 45/2: 207–38.[Crossref], [Web of Science ®] , [Google Scholar], 2011b Stanley, Jason 2011b. Know How, Oxford: Oxford University Press.[Crossref] , [Google Scholar]] maintain that knowledge-how just is a kind of knowledge-that. Accordingly, reductive intellectualists must predict that the value problems facing propositional knowledge will equally apply to knowledge-how. We show, however, that this is not the case. Accordingly, we highlight a value-driven argument for thinking (contra reductive intellectualism) that knowledge-how and knowledge-that come apart.     

Psychophysiological Arousal and Perceived Support during Couple Support Interactions: The Role of Attachment Anxiety and Avoidance

Abstract

Couple support processes—typically occurring in the context of non-relationship distressing issues—are crucial to our understanding of relationships (Pasch, Bradbury, & Sullivan, 1997 Pasch, L. A., Bradbury, T. N., & Sullivan, K. T. (1997). Social support in marriage: An analysis of intraindividual and interpersonal components. In G. R. Pierce, B. Lakey, & I. G. Sarson (Eds.), Sourcebook of social support and personality (pp. 229–256). New York, NY: Plenum Press.[Crossref] , [Google Scholar]). These couple support processes influence important relationship outcomes, including relationship satisfaction and longevity (i.e., Collins & Feeney, 2010 Collins, N. L., & Feeney, B. C. (2010). An attachment theoretical perspective on social support dynamics in couples: Normative processes and individual differences. In K. T. Sullivan, & J. Davila (Eds.), Support processes in intimate relationships (pp. 89–120). New York, NY: Oxford University Press.[Crossref] , [Google Scholar]). In this study, we examined 51 couples’ support perceptions and physiological arousal during individually distressing support conversations. Using dyadic data analysis, results reveal important findings in terms of avoidant attachment and couple support perceptions. Additionally, significant results were found between attachment anxiety and psychophysiological arousal. Implications of the current findings for couple relationships and therapy are discussed.     

Concurrent Validity of the Pediatric Attention Disorders Diagnostic Screener for Children with ADHD

The present study examined the concurrent validity of a new computer-assisted ADHD screening system, the Pediatric Attention Disorders Diagnostic Screener (PADDS; Pedigo, Pedigo, &; Scott, 2006 Pedigo, T., Pedigo, K. and Scott, V. B. Jr. 2006. PADDS Pediatric ADHD Screener: An evidence-based assessment system for screening attention and executive disorders, clinical and users guide, Okeechobee, FL: Targeted Testing, Inc.  [Google Scholar]) in relation to the Test of Variables of Attention (TOVA; Greenberg, 1999 Greenberg, L. M. 1999. Test of Variables of Attention, Los Alamitos, CA: The Tova Company.  [Google Scholar]), the Conner's Continuous Performance Test- II (CPT-II; Conners &; MHS Staff, 2000 Conners, C. K. and MHS Staff. 2000. Conner's continuous performance test II, Toronto: Multi-Health Systems.  [Google Scholar]), and the Behavior Rating Inventory of Executive Function (BRIEF; Gioia, Isquith, Guy, &; Kenworthy, 2000 Gioia, G. A., Isquith, P. K., Guy, S. C. and Kenworthy, L. 2000. Behavior Rating Inventory of Executive Function: Professional Manual, Lutz, FL: Psychological Assessment Resources, Inc.  [Google Scholar]) in three clinically referred samples of children 6 to 12 years of age. The PADDS is a recently published multidimensional screening measure that incrementally merges computer-administered executive tasks with parent and teacher behavior ratings to aid in the diagnostic decision-making process for youth with attention disorders. To date, no published study has examined the concurrent validity of the PADDS. In a clinic-referred sample of 217 subjects diagnosed with ADHD concurrent validity was assessed through correlation coefficients, paired t-tests (p < .001), and Cohen's d effect sizes. In comparison to the TOVA, the CPT-II, and the BRIEF scales, the PADDS demonstrated strong concurrent validity between conceptually similar scales, providing initial evidence for the concurrent validity of the PADDS. Relative to other measures, the PADDS appears to have some unique scales designed to assess attention and various aspects of executive functioning.     

Defense Mechanism Card Pull in TAT Stories

This study investigates the question of whether different Thematic Apperception Test (TAT; Murray, 1943 Murray, H. (1943). Thematic Apperception Test manual. Cambridge, MA: Harvard University Press. [Google Scholar]) cards are likely to prompt stories that are characterized by different defense mechanisms. This condition is known as card pull and refers to the probability that different TAT cards elicit different personality scores for the same variable. If so, the assessment of defense use would be importantly influenced by the TAT cards used in an assessment. TAT stories from 3 different community samples were examined (Ns = 91, 98, 121), using a statistical method developed by Stein et al (2014 Stein, M. B., Slavin-Mulford, J., Siefert, C. J., Sinclair, S. J., Renna, M., Malone, J., … Blais, M. A. (2014). SCORS–G stimulus characteristics of select Thematic Apperception Test cards. Journal of Personality Assessment, 96, 339–349.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). The results indicated that different TAT cards pull for different defenses, as assessed by the Defense Mechanism Manual (DMM: Cramer, 1991b Cramer, P. (1991b). The development of defense mechanisms: Theory, research and assessment. New York, NY: Springer-Verlag.[Crossref] , [Google Scholar]). However, the nature of card pull was not always consistent across samples. These dissimilarities could be due to group differences, or to the presence of different TAT cards used in the test battery, indicating that card pull is importantly determined by context.     

The Impact of R-Optimized Administration Modeling Procedures on Brazilian Normative Reference Values for Rorschach Scores

To generate normative reference data for the Rorschach Performance Assessment System (R–PAS), modeling procedures were developed to convert the distribution of responses (R) in protocols obtained using Comprehensive System (CS; Exner 2003 Exner, J. E. (2003). The Rorschach: A Comprehensive System. Vol. 1. Basic foundations (4th ed.). Hoboken, NJ: Wiley. [Google Scholar]) administration guidelines to match the distribution of R in protocols obtained using R-Optimized Administration (Meyer, Viglione, Mihura, Erard, &; Erdberg, 2011 Meyer, G. J., Viglione, D. J., Mihura, J. L., Erard, R. E., &; Erdberg, P. (2011). Rorschach Performance Assessment System: administration, coding, interpretation, and technical manual. Toledo, OH: Rorschach Performance Assessment System. [Google Scholar]). This study replicates the R–PAS study, examining the impact of modeling R-Optimized Administration on Brazilian normative reference values by comparing a sample of 746 CS administered protocols to its counterpart sample of 343 records modeled to match R-Optimized Administration. The results were strongly consistent with the R–PAS findings, showing the modeled records had a slightly higher mean R and, secondarily, slightly higher means for Complexity and V-Comp, as well as smaller standard deviations for R, Complexity, and R8910%. We also observed 5 other small differences not observed in the R–PAS study. However, when comparing effect sizes for the differences in means and standard deviations observed in this study to the differences found in the R–PAS study, the results were virtually identical. These findings suggest that using R-Optimized Administration in Brazil might produce normative results that are similar to traditional CS norms for Brazil and similar to the international norms used in R–PAS.     

Competitive state anxiety and self-confidence: Intensity and direction as relative predictors of performance on a golf putting task

Abstract

This study considered relationships between the intensity and directional aspects of competitive state anxiety as measured by the modified Competitive Sport Anxiety Inventory-2(D) (Jones & Swain, 1992 Jones, G. and Swain, A. B. J. 1992. Intensity and direction as dimensions of competitive state anxiety and relationships with competitiveness. Perceptual and Motor Skills, 74: 467–472. [Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) in a sample of 12 experienced male golfers. Anxiety and performance scores from identical putting tasks performed under three different anxiety-manipulated competitive conditions were used to assess both the predictions of Multidimensional Anxiety Theory (MAT; Martens et al., 1990 Martens, R., Burton, D., Vealey, R., Bump, L. and Smith, D. 1990. “The development of the Competitive State Anxiety Inventory-2 (CSAI-2)”. In Competitive anxiety in sport, Edited by: Martens, R., Vealey, R. S. and Burton, D. 117–190. Champaign, IL: Human Kinetics.  [Google Scholar]) and the relative value of intensity and direction in explaining performance variance. A within-subjects regression analysis of the intra-individual data showed partial support for the three MAT hypotheses. Cognitive anxiety intensity demonstrated a negative linear relationship with performance, somatic anxiety intensity showed a curvilinear relationship with performance, and self-confidence intensity revealed a positive linear relation. Cognitive directional anxiety illustrated a positive linear relationship with putting performance. Multiple regression analyses indicated that direction (42% of variance) was a better predictor of performance than intensity (22%)     

Exploring the Relationship Between Autistic Traits and Body Image,Body Satisfaction,and Body Competence

Autism spectrum disorders (ASD) have been linked to bodily disorders (anorexia nervosa, obesity), and individuals with ASD are known to experience unique bodily states (e.g., exaggerated interoceptive sensitivity). Though there is evidence to suggest body variables may significantly impact quality of life in those with ASD, research has yet to examine the potential relationship between ASD and body image variables, that is, the evaluation of one's body. The present study examined 80 healthy college students (40 male, 40 female) who completed an online set of questionnaires regarding body image and satisfaction, body competency, depression, anxiety, and autistic traits (Autism Spectrum Quotient, or AQ) (Baron-Cohen, Wheelwright, Skinner, Martin, &; Clubley, 2001 Baron-Cohen, S., Wheelwright, S., Skinner, R., Martin, J., &; Clubley, E. (2001). The autism spectrum quotient (AQ): Evidence from asperger syndrome/high-functioning autism, males and females, scientists, and mathematicians. Journal of Autism and Developmental Disorders, 31, 5–17.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Of primary interest was whether AQ scores, gender, and the interaction between AQ scores and gender could successfully predict participants' scores on body image, satisfaction, and competency scales. Autistic traits were only a significant predictor of scores on one measure of momentary body image and satisfaction (Body Image States Scale: Cash et al., 2002 Cash, T. F., Fleming, E. C., Alindogan, J., Steadman, L., &; Whitehead, A. (2002). Beyond body image as a trait: The development and validation of the body image states scale. Eating Disorders, 10, 103–113. https://doi.org/10.1080/10640260290081678[Taylor &; Francis Online] , [Google Scholar]). However, our results did suggest the possibility of an interaction between gender and AQ scores in predicting reports of body image, satisfaction, and competency.     

Millon's Contributions to Preadolescent and Adolescent Personality Assessment: Searching Onward and Upward

Theodore Millon was one of the most influential personality theorists of the 20th century. His theory was originally rooted in biosocial learning models and later reconceptualized as an evolutionary model. This foundation of Millon's work encompasses the entire life span. He had a genuine concern for humankind, especially children. His theory encompasses a comprehensive understanding of the relationship among childhood experiences, parenting styles, and recurring events throughout the life span in shaping the personality. Notable contributions to child and adolescent assessment are the Millon Adolescent Personality Inventory (Millon, Green, & Meagher, 1982 Millon, T., Green, C., & Meagher, R. B. (1982). Millon Adolescent Personality Inventory manual. Minneapolis, MN: National Computer Systems. [Google Scholar]), the Millon Adolescent Clinical Inventory (Millon, Millon, & Davis, 1993 Millon, T., Millon, C., & Davis, R. (1993). Millon Adolescent Clinical Inventory manual. Minneapolis, MN: National Computer Systems. [Google Scholar]), and the Millon Pre-Adolescent Clinical Inventory (M–PACI; Millon, Tringone, Millon, & Grossman, 2005 Millon, T., Tringone, R., Millon, C., & Grossman, S. (2005). Millon Pre-Adolescent Clinical Inventory manual. Minneapolis, MN: Pearson. [Google Scholar]). Given Millon's influence on the personality disorders section of the Diagnostic and Statistical Manual of Mental Disorders (DSM), the aforementioned instruments have personality constructs tied to familiar DSM categories, and among them, cover the age range of 9 to 18 years old. His development of the Millon Inventories revolutionized personality assessment in the United States and abroad. Millon's legacies will live on through his works and through the respect and compassion he demonstrated toward others.     

Predictors of the Strain Experienced by Professional Australian Footballers

The present study investigated the relationship between imagery use, leisure-time exercise, and exercise self-efficacy within a diverse range of exercisers. One hundred and sixty-two participants (M_age = 23.84; SD = 7.09; 97 female, 65 male) completed the Exercise Imagery Inventory (EII; Giacobbi, Hausenblas, &; Penfield, 2005 Giacobbi, P. R., Hausenblas, H. A. and Penfield, R. D. 2005. Further refinements in the measurement of exercise imagery: The Exercise Imagery Inventory. Measurement in Physical Education and Exercise Science, 9: 251–266. [Taylor &; Francis Online] , [Google Scholar]), the Leisure-Time Exercise Questionnaire (Godin &; Shepherd, 1985 Godin, G. and Shepard, R. J. 1985. A simple method to assess exercise behavior in the community. Canadian Journal of Applied Sport Science, 10: 141–146. [PubMed] , [Google Scholar]), and an exercise self-efficacy scale (Rodgers &; Sullivan, 2001 Rodgers, W. M., Munroe, K. and Hall, C. 2001. Relations among exercise imagery, self-efficacy, exercise behavior, and intentions. Imagination, Cognition, and Personality, 21: 55–65.  [Google Scholar]) directly following an exercise session. The EII was also modified to include two rating scales of visual and kinesthetic imagery ability. Separate hierarchical multiple regression analyses determined that appearance-health imagery significantly predicted exercise behavior and coping efficacy, and technique imagery significantly predicted task efficacy (all p < .001). Furthermore, exercisers’ abilities to create appearance-health images moderated the relationship between imagery frequency and leisure-time exercise, coping efficacy, and scheduling efficacy (all p < .05). These findings suggest that appearance-health and technique imagery may lead to an increase in exercise behavior and self-efficacy beliefs.     

Assessing Reflective Parenting in Interaction With School-Aged Children

The aim of this study was to examine whether it was possible to develop a reliable and valid assessment of reflective parenting implicit in interaction with school-aged children using an adaptation of the Squiggle paradigm developed by Winnicott (1968 Winnicott, D. W. (1968). Playing: Its theoretical status in the clinical situation. International Journal of Psycho-Analysis, 49, 591–599.[PubMed], [Web of Science ®] , [Google Scholar]) and a manualized coding system (Normandin, Leroux, Ensink, Terradas, &; Fonagy, 2015 Normandin, L., Leroux, A., Ensink, K., Terradas, M. M., &; Fonagy, P. (2015). Reflective Parenting Assessment coding manual (Unpublished manual). University Laval, Québec City, QC, Canada. [Google Scholar]). A total of 158 mother–child dyads participated when children were age 5 to 12. Of this group, 89 children had experienced sexual abuse. Interrater reliability using the manualized coding system was excellent. The factor analysis identified a reflective parenting stance factor, in addition to an affectionate support factor and a negative parenting factor. Furthermore, there was a medium strength relationship between the mother's reflective parenting stance evident in her interactions with her child and parental reflective functioning assessed using the Parent Development Interview (Slade, Aber, Bresgi, Berger, &; Kaplan, 2004 Slade, A., Aber, J. L., Bresgi, I., Berger, B., &; Kaplan, M. (2004). The Parent Development Interview–Revised (Unpublished protocol). The City University of New York, New York, NY. [Google Scholar]), suggesting the parental reflective stance is a good indicator of parental reflective functioning in interaction. With regard to parent reports of child internalizing and externalizing behaviors, the reflective parenting stance was the only predictor of internalizing difficulties and a significant predictor of externalizing difficulties in addition to sexual abuse.     

Conceptual and Procedural Knowledge During Strategy Construction: A Complex Knowledge Systems Perspective

ABSTRACT

This article elaborates a new direction for studying the construction of novel strategies that enables researchers to model the conceptual underpinnings of students' observable strategic actions during episodes of mathematical problem solving. The nature of the relationship between conceptual and procedural knowledge has been persistently debated for decades. Recently, there has been mounting empirical evidence that conceptual and procedural knowledge can develop by mutual bootstrapping in a bidirectional and iterative fashion (e.g., Rittle-Johnson & Schneider, 2014 Rittle-Johnson, B., & Schneider, M. (2014). Developing conceptual and procedural knowledge of mathematics. In R. C. Kadosh & A. Dowker (Eds.), Oxford handbook of numerical cognition (pp. 1102–1118). Oxford: Oxford University Press. [Google Scholar]). However, the very constructs of conceptual and procedural knowledge (especially procedural knowledge) have been critiqued for inconsistency in definition and lack of operationalization (Star, 2007 Sherin, B. L. (1996). The symbolic basis of physical intuition A study of two symbol systems in physics instruction (Doctoral dissertation). University of California, Berkeley. [Google Scholar]). The analysis in this article addresses this critique by modeling the diverse forms of conceptual and procedural knowledge needed to implement a strategy as a complex knowledge system: a strategy system. Furthermore, the strategy system model is used to elaborate processes of mutual bootstrapping between conceptual and procedural knowledge at a moment-by-moment time scale. The strategy system model builds upon the Knowledge in Pieces epistemological perspective (diSessa, 1993 diSessa, A. A. (1993). Toward an epistemology of physics. Cognition and Instruction, 10(2–3), 105–225. doi:10.1080/07370008.1985.9649008[Taylor & Francis Online], [Web of Science ®] , [Google Scholar]), and coordination class theory in particular (diSessa & Wagner, 2005 diSessa, A. A., & Wagner, J. F. (2005). What coordination has to say about transfer. In J. P. Mestre (Ed.), Transfer of learning from a modern multidisciplinary perspective (pp. 121–154). Greenwich, CT: Information Age Publishing. [Google Scholar]). Both the theoretical notion of a strategy system and the bidirectional model of mutual bootstrapping between conceptual and procedural knowledge are illustrated using data from a case study of a pre-algebra student who iteratively refined a procedure for solving algebra word problems. The strategy system model highlights the complexity of both strategies and concepts and offers a window into what can be learned by students during strategy construction processes.
