Application of Latent Semantic Analysis to Divergent Thinking is Biased by Elaboration

Scoring divergent‐thinking response sets has always been challenging because such responses are not only open‐ended in terms of number of ideas, but each idea may also be expressed by a varying number of concepts and, thus, by a varying number of words (elaboration). While many current studies have attempted to score the semantic distance in divergent‐thinking responses by applying latent semantic analysis (LSA), it is known from other areas of research that LSA‐based approaches are biased according to the number of words in a response. Thus, the current article aimed to identify and demonstrate this elaboration bias in LSA‐based divergent‐thinking scores by means of a simulation. In addition, we show that this elaboration bias can be reduced by removing the stop words (for example, and, or, for and so forth) prior to analysis. Furthermore, the residual bias after stop word removal can be reduced by simulation‐based corrections. Finally, we give an empirical illustration for alternate uses and consequences tasks. Results suggest that when both stop word removal and simulation‐based bias correction are applied, convergent validity should be expected to be highest.     

Divergent Thinking,Intelligence, and Expertise: A Test of Alternative Models

Given the creativity inherent in advertising, one useful measure of creativity may be the advertising creativity award. Although creativity awards have been used by academics, agencies, and clients as indicators of exemplary creative work, there is surprisingly little research as to what creative elements they actually represent. Senior agency executives were selected to assess their own campaigns in terms of originality and strategy, and were also queried about whether those campaigns would win creativity, and effectiveness, awards. Findings show that the campaigns deemed worthy of creativity award recognition are usually highly original. Yet, most award-winning work is rarely regarded as being highly strategic. The results indicate that this originality bias contained in award-winning advertisements may limit their usefulness as proxy measures of creativity. Although the originality aspect of creativity is reflected, strategy and appropriateness are not adequately, nor proportionately considered. Implications for the use of creativity awards by researchers, as well as managerial issues, are discussed.     

Latent Profile Analysis of Observed Parenting Behaviors in a Clinic Sample

We examined typologies of parenting practices using latent profile analysis (LPA) in a sample of families with young children who had externalizing behavior disorders. We also examined mother and child characteristics associated with class membership using ratings from multiple informants. The sample included pooled data from five parenting treatment outcome research studies on oppositional defiant disorder (ODD) and/or conduct disorder (CD) conducted throughout the past 20 years. These studies included 21 separate cohorts of children resulting in a total of 514 families. All children met diagnostic criteria for ODD or CD and 78 % were male. Parenting practices were observed by independent raters using the Dyadic Parent–child Interactive Coding System-Revised (DPICS-R). Four summary scores (i.e., total critical statements, total commands, total positive, total supportive) from the DPICS-R were used as class indictors in the LPA. Four classes best characterized the parenting practices of this clinic sample, roughly comprising a quarter of the sample each: Positive Only, Negative Only, Positive/Negative, and Neither Positive/Negative. High observed child negative behaviors, low observed child warmth, high socioeconomic status, and low academic performance distinguished the two classes with high negative behaviors (Negative Only, Positive/Negative) from the other classes. These results provide markers of the most common parenting profiles at entry into treatment programs for behavior disorders in young children. Findings have significant implications for the tailoring parenting interventions and supports to specific family needs.     

Latent Profile Analysis of Psychopathy in Chinese Female Offenders

The present study aimed to identify meaningful subtypes of psychopathy among Chinese female offenders. A Latent Profile Analysis (LPA) based on the scores of the Levenson Self-Report Psychopathic Scale was performed in a sample of Chinese female prisoners (N?=?279, M age?=?45.43, SD?=?8.62). The LPA yielded three profiles: “low psychopathy group” (27.6%), “moderate psychopathy group” (66.7%), and “high egocentricity and antisocial group” (5.7%). These profiles differed on all outcome variables including anxiety, depression, reactive aggression, and proactive aggression. The high egocentricity and antisocial group had a greater risk for anxiety, recidivism, impulsiveness, and aggression. Overall, the findings support the existence of psychopathy subtypes in non-Western cultural contexts, suggest gender similarities in the manifestation of psychopathy traits, and further the understanding of psychopathy typologies.

Information,Experience, and Divergent Thinking: An Empirical Test

ABSTRACT: Divergent thinking tests are often used to estimate the potential for creative problem solving. Scores on these tests may, however, reflect a kind of experiential bias. Similar biases once plagued IQ tests, the idea being that scores reflect the individual's background and information in long-term memory as much as ability per se. The investigation reported here attempted to assess the role of experience, knowledge, and memory in divergent thinking by comparing 2 kinds of tasks. One was a standard divergent thinking task (e.g., "list uses for a shoe," "uses for a brick," "uses for a newspaper"). The other allowed a number of responses but required that the examinee produce factual, knowledge- based responses. A second objective here was to compare standard- and knowledge-based ideation with tasks that shared 1 domain (e.g., transportation) with tasks that did not share a domain. Results indicated that there was a statistically significant correlation between the 2 types of tasks but only when they shared 1 domain. This was confirmed with product–moment correlations (r = .37, p = .025) and a canonical correlation (Rc = .69, p = 008). The correlations were not significant when the tasks represented different domains. It is interesting to note that both the knowledge-based and the standard divergent thinking tasks were unrelated to grade point average, which supports their discriminant validity. Limitations and directions for future research are suggested.     

Identifying the Career-Interest Profiles of Junior-High-School Students Through Latent Profile Analysis

Exploring the career-interest profiles of students has both practical and theoretical significance; however, a minimal amount of research has been conducted to address this issue. The present study combined latent profile analysis and differentiation values to investigate the career-interest profiles of 13,853 junior-high-school students. The results indicate that while the students’ interests could be stratified into 25 profiles, 44.6% of students could be classified the as having low-differentiation profiles (such as like or dislike all types of vocational activities) and 24.9% of students could be classified the as having the artistic-social (like both artistic and social types of activities) profile. In addition, the proportions of females and males differed significantly among the profiles, but different grades did not. The proportion of males was higher for all three low-differentiation groups than of female proportions. Implications for career practices and future research are proposed.     

A Latent Block Distance-Association Model for Profile by Profile Cross-Classified Categorical Data

Abstract

Distance association models constitute a useful tool for the analysis and graphical representation of cross-classified data in which distances between points inversely describe the association between two categorical variables. When the number of cells is large and the data counts result in sparse tables, the combination of clustering and representation reduces the number of parameters to be estimated and facilitates interpretation. In this article, a latent block distance-association model is proposed to apply block clustering to the outcomes of two categorical variables while the cluster centers are represented in a low dimensional space in terms of a distance-association model. This model is particularly useful for contingency tables in which both the rows and the columns are characterized as profiles of sets of response variables. The parameters are estimated under a Poisson sampling scheme using a generalized EM algorithm. The performance of the model is tested in a Monte Carlo experiment, and an empirical data set is analyzed to illustrate the model.     

Developing a Validity Argument Through Abductive Reasoning with an Empirical Demonstration of the Latent Class Analysis

This article proposes and demonstrates a methodology for test score validation through abductive reasoning. It describes how abductive reasoning can be utilized in support of the claims made about test score validity. This methodology is demonstrated with a real data example of the Canadian English Language Proficiency Index Program (CELPIP)-General test—a program assessing functional English language ability in the community and workplace. Abductive reasoning seeks the enabling conditions through which a claim about a person's ability makes sense. For example, it makes sense that a person has strong functional language proficiency if he or she has been regularly using English to write emails and meet with colleagues at work. A valid test score should be affected by the extent of a person's engagement with such enabling conditions. Empirical evidence that warrants such an abductively reasoned claim is illustrated through a latent class analysis within a structural equation model. Evidence is examined to investigate whether certain classes of test takers who have been differentially engaging in the enabling conditions do, in fact, predict a person's CELPIP-General performance. The steps of the methodology are summarized in the closing section.     

A Latent Profile Analysis of Co-occurring Youth Posttraumatic Stress and Conduct Problems Following Community Trauma

Although most research with youth exposed to violent manmade disasters has focused on internalizing problems, recent work suggests conduct problems (CPs) may also manifest in exposed youth. However, the extent to which youth postevent CPs present independently, versus co-present in conjunction with PTSD symptoms, remains unclear. The present study examined PTS and CP symptom profiles among affected Boston-area youth following the 2013 Boston Marathon bombing. This study used latent profile analysis to identify distinct PTS and CP symptom profiles among Boston-area youth ages 4–19 years (N?=?344) affected by the Boston Marathon bombing events. PTS and CPs were measured using the UCLA-PTSD-RI and the SDQ parent reports, respectively. Analyses identified 3 distinct profiles: presentations characterized by (a) low PTS, low CPs, (b) moderate PTS, low CPs, and (c) high PTS, elevated CPs. The profile characterized by the highest PTS was the only profile with elevated CPs; hyperarousal and emotional numbing/avoidance symptoms showed the greatest distinguishing properties among profiles with and without elevated CP. Types of traumatic exposure experienced by youth were differentially associated with profiles. Specifically, direct (but not relational) exposure distinguished youth classified in the profile showing elevated CPs. Findings suggest interventions following violent manmade disasters may do well to incorporate CP modules when working with youth showing the greatest hyperarousal and emotional numbing, and/or who have directly witnessed the most violence.     

Construct Validity of the Relationship Profile Test: Links With Measures of Psychopathology and Adult Attachment

This study assessed the construct validity of the Relationship Profile Test (RPT; Bornstein &; Languirand, 2003 Bornstein, R. F., &; Languirand, M. A. (2003). Healthy dependency. New York, NY: Newmarket. [Google Scholar]) with a substance abuse sample. One hundred-eight substance abuse patients completed the RPT, Experiences in Close Relationships Scale–Short Form (Wei, Russell, Mallinckrodt, &; Vogel, 2007 Wei, M., Russell, D. W., Mallinckrodt, B., &; Vogel, D. L. (2007). The Experience in Close Relationships Scale (ECR)–Short Form: Reliability, validity and factor structure. Journal of Personality Assessment, 88, 187–204.[Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]), Personality Assessment Inventory (Morey, 1991 Morey, L. C. (1991). Personality Assessment Inventory professional manual. Odessa, FL: Psychological Assessment Resources. [Google Scholar]), and Symptom Checklist–90–Revised (Derogatis, 1983 Derogatis, L. R. (1983). SCL–90–R administration, scoring, and procedures manual II. Towson, MD: Clinical Psychometric Research. [Google Scholar]). Results suggest that the RPT has good construct validity when compared against theoretically related broadband measures of personality, psychopathology, and adult attachment. Overall, health dependency was negatively related to measures of psychopathology and insecure attachment, and overdependence was positively related to measures of psychopathology and attachment anxiety. Many of the predictions regarding RPT detachment and the criterion measures were not supported. Implications of these findings are discussed.     

Benefits of Incubation on Divergent Thinking

Studies on whether fixation cues provided in the first episode of divergent thinking tasks influence creative outcomes after incubation, as they do for convergent problem-solving tasks, remain limited. This research examined the beneficial effects of incubation using the delayed- and immediate-incubation paradigms. Participants in Experiment 1 were either provided or not provided fixation cues during the first episode of a new type of divergent-thinking task, similar to creating titles in plot stories. The results indicated that fixation cues moderated people’s creative outcomes after incubation. Going through incubation did not improve the participants’ creativity in the second episode for strong fixation cues. By contrast, an incubation period led to the generation of more divergent items in the second episode compared to the first episode for less strong fixation cues, and this led to the performance matching the condition without fixation cues. The results from Experiment 2 suggested that immediate incubation downsized the influence of fixation cues. Therefore, if people want to promote their creativity through a period of incubation, the outcomes may still depend on the conditions of environments in which the creative works are executed.     

潜在剖面模型的后续分析——比较分类分析法改进后的偏差

传统的分类分析法虽然是潜在类别模型常用的后续分析方法,但容易导致后续模型中潜在类别与其他变量之间关系的低估。现阶段已发展出多种改进的方法:一步法、基于模型的方法、Bartlett法,改进的分类分析法(包括ML三步法、BCH法、纳入式分类分析法)。本文对这些方法研究进行综述总结,进一步针对心理学研究数据的特点,使用模拟实验探讨适用于潜在剖面模型的分类分析方法,结果发现:传统方法低估潜在类别变量与因变量的关系;ML三步法只有在潜在类别概率分布平均时估计精确;BCH法估计最接近真值,但在低分类区分度、大效果量时出现概率估计为负值的情况;纳入法虽有轻微的高估,但在各种模拟条件下参数估计最为稳健。这些方法受分类区分度、类别概率均匀性以及潜在类别变量与附属变量关系的效果量所影响。     

History Assessments of Thinking: A Validity Study

This article reports a validity study of History Assessments of Thinking (HATs), which are short, constructed-response assessments of historical thinking. In particular, this study focuses on aspects of cognitive validity, which is an examination of whether assessments tap the intended constructs. Think-aloud interviews with 26 high school students were used to examine the thinking elicited by 8 HATs and multiple-choice versions of these tasks. Results showed that although both HATs and multiple-choice items tapped historical thinking processes, HATs better reflected student proficiency in historical thinking than their multiple-choice counterparts. Item format also influenced the thinking elicited, with multiple-choice items eliciting more instances of construct-irrelevant reasoning than the constructed-response versions. Implications for history assessment are discussed.     

Posttraumatic Stress Disorder and executive dysfunction among children and adolescents: A Latent Profile Analysis

Background/ObjectiveThe current study aimed to examine the relationship between Posttraumatic Stress Disorder (PTSD) symptoms and executive dysfunction in children and adolescents after psychological trauma.MethodParticipants were 13,438 of children and adolescents aged 6 to 18 years exposed to the 2008 Wenchuan earthquake. PTSD and dysexecutive symptoms were assessed using the UCLA PTSD Reaction Index for Children and the Self-Report Dysexecutive Questionnaire. Latent Profile Analysis (LPA) was conducted using Mplus version 7.4. Subgroup differences in trauma exposure and quality of life were calculated using ANCOVA.ResultsA 4-class parallel model was found to best describe latent PTSD symptom profiles and executive dysfunction. Individuals in higher symptom groups showed more trauma exposure and lower quality of life.ConclusionsThis LPA study shed light on the relationship between PTSD and executive dysfunction symptoms in children and adolescents. The correlation between PTSD and executive dysfunction was maintained after individual differences were taken into consideration. Our findings provide a new view on how PTSD relates to executive dysfunction and several suggestions for treating child and adolescent PTSD patients.     

Convergent Thinking Moderates the Relationship between Divergent Thinking and Scientific Creativity

Creativity plays an important role in human society as well as in individual development, and creativity in the domain of science is a specific form. A body of research had demonstrated the role of divergent thinking in creativity. The role of convergent thinking had also been recognized, but more empirical evidence was needed. To investigate the interaction between convergent and divergent thinking on adolescent scientific creativity, the current study tested 588 high school students. The results showed that convergent thinking interacted with fluency/flexibility of divergent thinking on scientific creativity. In particular, divergent thinking predicted creativity in those high in convergent thinking. Findings suggested a threshold-setting effect of convergent thinking, which meant only when convergent thinking capacity reached a certain level, divergent thinking could play a role in scientific creativity. Implications for future research and educational practice were discussed.     

A Latent Trait Analysis of the MMPI

Commonly used techniques for analyzing the structure of the MMPI scales were discussed and the use of a latent trait model was suggested as an alternative. The items on each scale of the MMPI were calibrated using a discrimination statistic. The item calibration statistics obtained from a replication sample were highly correlated with those obtained in the first sample. Poor fitting items were identified, and possible reasons for poor fits were discussed. The scales generally had few poor fits. The poor fitting items were generally those identified by Wiener (1956) as comprising the "subtle" subscales of the test.     

Theory of Mind and the Origin of Divergent Thinking

The development of a “theory of mind” may not only be important for understanding the minds of others but also for using one's own mind. To investigate this supposition, 40 children between the ages of three and four were given false-belief and creativity tasks. The numbers of appropriate and of original responses in the creativity test were found to correlate positively with performance on false-belief tasks. This association was robust, as it continued to be strong and significant even when age and verbal intelligence were partialled out. The results support the hypothesis that the metarepresentational skills involved in theory of mind also affect the way children can access and scan their own mental repertoire beyond the areas of currently activated content (i.e. divergent thinking). With the advent of theory of mind a basic cognitive shift takes place in human development, and possibly took place in cognitive evolution.
