<Emphasis Type="Italic">Harry Potter</Emphasis> and the sorcerer's scope: latent scope biases in explanatory reasoning

What makes a good explanation? We examine the function of latent scope, i.e., the number of unobserved phenomena that an explanation can account for. We show that individuals prefer narrow latent scope explanations—those that account for fewer unobserved effects—to broader explanations. In Experiments 1a–d, participants found narrow latent scope explanations to be both more satisfying and more likely. In Experiment 2 we directly manipulated base rate information and again found a preference for narrow latent scope explanations. Participants in Experiment 3 evaluated more natural explanations of unexpected observations, and again displayed a bias for narrow latent scope explanations. We conclude by considering what this novel bias tells us about how humans evaluate explanations and engage in causal reasoning.     

Why Power Decreases Happiness in a Collectivist Context? A Qualitative Study

In the Western settings, power positively predicted happiness (e.g., Kifer et al. 2013). Though, this result may not be generalized across cultures as cultural psychologists recognized that interdependence is more important in collectivist cultures. Consistent with this conjecture, Datu and Reyes (2014) assessed the relations among power, relations, and happiness in the Philippine setting which revealed that power negatively predicted happiness. However, not much is known on why power could potentially reduce happiness in collectivist cultures. Thus, the current investigation employed qualitative research to offer in-depth explanations on why power may be associated with lower happiness in a collectivist setting. Findings revealed three major themes that characterized reasons on why power may decrease happiness in an interdependent context: a.) Power impairs relationship; b.) Power evokes negative judgments from others; and c.) Power comes with a great responsibility. The theoretical and practical implications of these results are discussed.     

Children’s success at detecting circular explanations and their interest in future learning

These studies explore elementary-school-aged children’s ability to evaluate circular explanations and whether they respond to receiving weak explanations by expressing interest in additional learning. In the first study, 6-, 8-, and 10-year-olds (n = 53) heard why questions about unfamiliar animals. For each question, they rated the quality of single explanations and later selected the best explanation between pairs of circular and noncircular explanations. When judging single explanations, 8- and 10-year-olds, and to some extent 6-year-olds, provided higher ratings for noncircular explanations compared to circular ones. When selecting between pairs of explanations, all age groups preferred noncircular explanations to circular ones, but older children did so more consistently than 6-year-olds. Children who recognized the weakness of the single circular explanations were more interested in receiving additional information about the question topics. In Study 2, all three age groups (n = 87) provided higher ratings for noncircular explanations compared to circular ones when listening to responses to how questions, but older children showed a greater distinction in their ratings than 6-year-olds. Moreover, the link between recognizing circular explanations as weak and interest in future learning could not be accounted for solely by individual differences in verbal intelligence. These findings illustrate the developmental trajectory of explanation evaluation and support that recognition of weak explanations is linked to interest in future learning across the elementary years. Implications for education are discussed.     

The scope of formal explanation

The existence of multiple modes of explanation means that a crucial step in the process of generating explanations has to be selecting a particular mode. The present article identifies the key conceptual, as well as some pragmatic and epistemological, considerations that license the use of the formal mode of explanation, and thus that enter into the process of selecting and generating a formal explanation. Formal explanations explain the presence of certain properties in an instance of a kind by reference to the kind of thing it is (e.g. That has four legs because it is a dog). As such, this mode of explanation is intrinsically tied to kind representations and is applicable domain-generally. Although it is possible for formal explanation to apply domain-generally, for any given kind it is selective in its application, in that it can explain some, but not all, properties of the instances of a kind. It also appears that different types of properties can receive formal explanations across different domains. This article provides a sketch of a theory of the selectivity of formal explanation that results from the manner in which kinds of different types are distinguished. The present discussion also suggests how the mechanisms underlying formal explanations may contribute to the illusion of explanatory depth Keil (Trends in Cognitive Sciences, 7, 368–373,2003), the operation of the inherence heuristic Cimpian & Salomon (Behavioral and Brain Sciences, 37, 461–480, 2014a; Behavioral and Brain Sciences, 37, 506–527,2014b), and psychological essentialism (Gelman, 2003).     

The Children’s Attention-Deficit Hyperactivity Disorder Telemental Health Treatment Study: Caregiver Outcomes

The Children’s Attention-deficit Hyperactivity Disorder (ADHD) Telemental Health Treatment Study (CATTS) tested the hypotheses that children and caregivers who received guideline-based treatment delivered through a hybrid telehealth service delivery model would experience greater improvements in outcomes than children and caregivers receiving treatment via a comparison delivery model. Here, we present caregiver outcomes. 88 primary care providers (PCPs) in seven geographically underserved communities referred 223 children (ages 5.5 ? 12.9 years) to the randomized controlled trial. Over 22 weeks, children randomized to the CATTS service delivery model received six sessions of telepsychiatry and six sessions of caregiver behavior management training provided in person by community therapists who were trained and supervised remotely. Children randomized to the comparison Augmented Primary Care (APC) service model received management in primary care augmented by a single telepsychiatry consultation. Caregiver outcomes included changes in distress, as measured by the Patient Health Questionnaire (PHQ-9), Parenting Stress Index (PSI), Caregiver Strain Questionnaire (CSQ) and Family Empowerment Scale (FES). Caregivers completed five assessments. Multilevel mixed effects regression modeling tested for differences between the two service delivery models in caregiver outcomes from baseline to 25 weeks. Compared to caregivers of children in the APC model, caregivers of children in the CATTS service model showed statistically significantly greater improvements on the PHQ-9 (β?=?-1.41, 95 % CI?=?[?2.74, ?0.08], p?<?.05), PSI (β?=??4.59, 95 % CI?=?[?7.87, ? 1.31], p?<?.001), CSQ (β?=??5.41, 95 % CI?=?[? 8.58, ?2.24], p?<?.001) and FES (β?=?6.69, 95 % CI?=?[2.32, 11.06], p?<?.01). Improvement in child ADHD symptoms mediated improved caregiver scores on the PSI and CSQ. Improvement in child ODD behaviors mediated caregiver CSQ scores. The CATTS trial supports the effectiveness of a hybrid telehealth service delivery model for reducing distress in caregivers of children with ADHD and suggests a mechanism through which the service model affected caregiver distress.     

The relevance of selecting what's relevant: A dual process approach to transitive reasoning with spatial relations

The present paper focuses on the heuristic selection process preceding the actual transitive reasoning process. A part of the difficulty of transitive reasoning lies in the selection of the relevant problem aspects. Two experiments are presented using the paradigm introduced by Markovits, Dumas, and Malfait (1995 Markovits, H., Dumas, C. and Malfait, N. 1995. Understanding transitivity of a spatial relationship: A developmental analysis. Journal of Experimental Child Psychology, 59: 124–141.  [Google Scholar]), in which children were asked to make “higher than” inferences about arrays of coloured blocks. In order to discriminate between genuine transitive inference and a simple strategy of relative position, Markovits et al. interspersed white blocks with the coloured blocks, such that the relative position strategy leads to erroneous responses. However, we argue that the white blocks cause confusion due to their ambiguity, which interferes with the heuristic selection process. Two methodological adaptations were introduced, which are hypothesised to facilitate the selection process and improve transitive reasoning: (1) the white blocks were replaced by coloured blocks, and (2) a less abstract context was added to the experimental design. The colour manipulation leads to a clear increase in the use of a transitive strategy by 9-year-old children; 8-year-old children mainly used the relative position strategy. When adding a context story, 9-year-old children used the transitive strategy regardless of the colour of the interspersed blocks. The overall performance of 8-year-olds improved slightly. These results are interpreted as support for a dual-process model of transitive reasoning.     

Emotion Regulation in Families of Children with Behavior Problems and Nonclinical Comparisons

The current study compared parents’ emotion regulation (ER) in clinical (those with a child with externalizing behavioral problems) and low-risk comparison families. Additionally, mediation models were explored with parent ER predicting child behavior problems through child ER. Participants were 60 families with children (71.7% boys; 73% Caucasian) ages 2 through 8 years (M?=?4.62; SD?=?1.69) from a rural population in the United States: 34 clinical families referred for parent training and 26 nonclinical families. A blocking design was used to balance the two groups on key demographic characteristics. Parents’ and children’s ER was assessed using parent-report surveys and structured behavioral observations. Analyses indicated higher rates of parental emotion dysregulation (specifically, more difficulty when upset with achieving goal-directed behaviors, p?=?.01, d?=?0.67; controlling impulses, p?=?.01, d?=?0.64; limited use of ER strategies, p?=?.02, d?=?0.62; and more negative verbalizations to their child during the observed task, p?<?.01, d?=?0.73) and child emotion dysregulation (specifically, more difficulty as reported by parents, p?<?.01, d?=??2.42) in the clinical group. Mediational analyses indicated there were indirect paths from parental ER to children’s behavioral problems through child ER. Findings from this research suggest a need to measure and target ER in both parents and their children when working with families who are referred for treatment of child behavior problems.     

Maternal Depression in Families of Children with ADHD: A Meta-Analysis

Although research has demonstrated a relationship between maternal depression and child attention deficit/hyperactivity disorder (ADHD); the strength of the relationship is currently unclear. The results of some studies have found a strong association between maternal depression and child ADHD, while other studies have found little or no association. A meta-analysis was conducted to clarify the strength of the association between maternal depression and child ADHD. The current study included 51 published and unpublished studies that included a quantitative comparison between maternal depression and child ADHD. Mothers of children with ADHD had significantly higher levels of depressive symptoms than mothers of children without ADHD (d?=?0.58; 95% CI [0.43, 0.74]; p?<?.001; k?=?18). The relationship between maternal depressive symptoms and child ADHD symptoms was moderate (r?=?.22; 95% CI [.17, .28]; p?<?.001; k?=?21). 17.11% of mothers of children with ADHD currently met criteria for a depressive disorder (95% CI [11.95, 23.89], p?<?.001, k?=?19). The DSM version used to evaluate child ADHD status was the only moderator that was statistically significant (p?=?.021, k?=?15). Specifically, studies that used the DSM-III or DSM-III-R were associated with larger effect sizes than studies that used the DSM-IV or DSM-IV-TR. The results suggest that clinicians should screen for the possible co-occurrence of maternal depression when working with families of children with ADHD.     

Grammatical Aspect in Early Child Mandarin: Evidence from a Preferential Looking Experiment

The study assessed 30-month-old Mandarin-speaking children’s awareness of aspectual distinctions involving the perfective marker le and the imperfective marker zhe in a preferential looking experiment. In the experiment, we presented our child subjects with a choice between two video clips (one depicting a closed event and the other depicting an on-going event), in the presence of an auditory stimulus (either the le sentence, the zhe sentence or the control sentence without any aspect marker). Children’s looking behavior in the task was recorded and analyzed. The results revealed 30-month-old children’s emerging sensitivity to the aspectual contrast between le and zhe. This was manifest by an increase in looking to the closed event when hearing the le sentence and an increase in looking to the on-going event when hearing the zhe sentence. The absence of le or zhe in the control sentence did not result in any increase or decrease in looking to either event. We also found that the effect of le on children’s looking behavior was immediate whereas the effect of zhe was late. We attributed this difference to the facilitative role of le in children’s sentence processing as well as their preference for the event boundary. The results lend support to the continuity view that functional morphemes like aspect markers are available to children early in language development.     

Intergenerational Transfers: Associations with Adult Children’s Emotional Support of Their Parents

This study investigates how different factors in regard to intergenerational relationships are associated with emotional support given by adults to their parents. The analysis focuses on adult children and their parents in a representative German sample. Data were obtained from the second wave of the German Family Panel (pairfam) consisting of 2064 women and 1841 men. Results show that transfer of emotional support by the adult children was especially associated not only with received emotional support from parents, but also with affection, conflicts, and expectations concerning parents. A moderator analysis focuses on gender and showed differences for the association between given support by adults and conflicts between mothers and fathers. For the offspring, no gender effects were found.     

Betting on transitivity in probabilistic causal chains

Causal reasoning is crucial to people’s decision making in probabilistic environments. It may rely directly on data about covariation between variables (correspondence) or on inferences based on reasonable constraints if larger causal models are constructed based on local relations (coherence). For causal chains an often assumed constraint is transitivity. For probabilistic causal relations, mismatches between such transitive inferences and direct empirical evidence may lead to distortions of empirical evidence. Previous work has shown that people may use the generative local causal relations A → B and B → C to infer a positive indirect relation between events A and C, despite data showing that these events are actually independent (von Sydow et al. in Proceedings of the thirty-first annual conference of the cognitive science society. Cognitive Science Society, Austin, 2009, Proceedings of the 32nd annual conference of the cognitive science society. Cognitive Science Society, Austin, 2010, Mem Cogn 44(3):469–487, 2016). Here we used a sequential learning scenario to investigate how transitive reasoning in intransitive situations with negatively related distal events may relate to betting behavior. In three experiments participants bet as if they were influenced by a transitivity assumption, even when the data strongly contradicted transitivity.     

Sit Down and Play: A Preventive Primary Care-Based Program to Enhance Parenting Practices

The primary care office offers an ideal setting to encourage parenting behaviors that promote early childhood development. We conducted a pilot study to establish feasibility and acceptability of Sit Down and Play (SDP), a brief primary care-based program to facilitate positive parenting behaviors through take-home play activities. A prospective 1-month study was conducted in an urban primary care clinic. SDP was administered to 30 caregivers of 6–12 month-old children while they waited for their well-child appointment. Caregivers completed baseline and 4-week follow-up surveys. Open-ended interview questions regarding acceptability and usefulness of SDP were administered and analyzed using content analysis. Parenting practices related to child development were measured with standardized measures and changes analyzed using paired t-test and linear mixed effects models. Most caregivers were mothers (90?%) and non-white (97?%); the majority of children received Medicaid (87?%). There were significant increases in parental reports of practices related to child development (p?<?0.001), including families who reported low incomes (i.e. <$25,000) and received a high-school education or less (p?=?0.001). Four main themes emerged from the open-ended interview data: (1) importance of play, (2) noticing a change in their child, (3) reinforcing existing positive parenting behaviors, and (4) satisfaction with the program. This preliminary study suggests that SDP is a feasible and potentially beneficial program that can be delivered during pediatric well-child visits. Further studies are needed to determine the effectiveness of SDP on parenting behaviors and developmental outcomes.     

<Emphasis Type="Italic">Wh</Emphasis>-Questions,Universal Statements and Free Choice Inferences in Child Mandarin

This study investigated 5-year-old Mandarin-speaking children’s comprehension of wh-questions, universal statements and free choice inferences. Previous research has found that Mandarin-speaking children assign a universal interpretation to sentences with a wh-word (e.g., shei ‘who’) followed by the adverbial quantifier dou ‘all’ (Zhou in Appl Psycholinguist 36:411–435, 2013). Children also compute free choice inferences in sentences that contain a modal verb in addition to a wh-word and dou (Zhou, in: Nakayama, Su, Huang (eds.) Studies in Chinese and Japanese language acquisition: in honour of Stephen Crain. John Benjamins Publishing Company, Amsterdam, pp 223–235, 2017). The present study used a Question-Statement Task to assess children’s interpretation of sentences containing shei + dou, both with and without the modal verb beiyunxu ‘was allowed to’, as well as the contrast between sentences with shei + dou, which are statements for adults, versus ones with dou + shei, which are wh-questions for adults. The 5-year-old Mandarin-speaking child participants exhibited adult-like linguistic knowledge of the semantics and pragmatics of wh-words, the adverbial quantifier dou, and the deontic modal verb beiyunxu.     

Substance concepts and personal identity

According to one argument for Animalism about personal identity, animal, but not person, is a Wigginsian substance concept—a concept that tells us what we are essentially. Person supposedly fails to be a substance concept because it is a functional concept that answers the question “what do we do?” without telling us what we are. Since person is not a substance concept, it cannot provide the criteria for our coming into or going out of existence; animal, on the other hand, can provide such criteria. This argument has been defended by Eric Olson, among others. I argue that this line of reasoning fails to show Animalism to be superior to the Psychological Approach, for the following two reasons: (1) human animal, animal, and organism are all functional concepts, and (2) the distinction between what something is and what it does is illegitimate on the reading that the argument needs.     

Analysis of the Talmudic Argumentum A Fortiori Inference Rule (Kal Vachomer) using Matrix Abduction

We motivate and introduce a new method of abduction, Matrix Abduction, and apply it to modelling the use of non-deductive inferences in the Talmud such as Analogy and the rule of Argumentum A Fortiori. Given a matrix \({\mathbb {A}}\) with entries in {0, 1}, we allow for one or more blank squares in the matrix, say a _i,j =?. The method allows us to decide whether to declare a _i,j = 0 or a _i,j = 1 or a _i,j =? undecided. This algorithmic method is then applied to modelling several legal and practical reasoning situations including the Talmudic rule of Kal-Vachomer. We add an Appendix showing that this new rule of Matrix Abduction, arising from the Talmud, can also be applied to the analysis of paradoxes in voting and judgement aggregation. In fact we have here a general method for executing non-deductive inferences.     

Characterizing belief bias in syllogistic reasoning: A hierarchical Bayesian meta-analysis of ROC data

The belief-bias effect is one of the most-studied biases in reasoning. A recent study of the phenomenon using the signal detection theory (SDT) model called into question all theoretical accounts of belief bias by demonstrating that belief-based differences in the ability to discriminate between valid and invalid syllogisms may be an artifact stemming from the use of inappropriate linear measurement models such as analysis of variance (Dube et al., Psychological Review, 117(3), 831–863, 2010). The discrepancy between Dube et al.’s, Psychological Review, 117(3), 831–863 (2010) results and the previous three decades of work, together with former’s methodological criticisms suggests the need to revisit earlier results, this time collecting confidence-rating responses. Using a hierarchical Bayesian meta-analysis, we reanalyzed a corpus of 22 confidence-rating studies (N =?993). The results indicated that extensive replications using confidence-rating data are unnecessary as the observed receiver operating characteristic functions are not systematically asymmetric. These results were subsequently corroborated by a novel experimental design based on SDT’s generalized area theorem. Although the meta-analysis confirms that believability does not influence discriminability unconditionally, it also confirmed previous results that factors such as individual differences mediate the effect. The main point is that data from previous and future studies can be safely analyzed using appropriate hierarchical methods that do not require confidence ratings. More generally, our results set a new standard for analyzing data and evaluating theories in reasoning. Important methodological and theoretical considerations for future work on belief bias and related domains are discussed.     

Eight-Year Latent Class Trajectories of Academic and Social Functioning in Children with Attention-Deficit/Hyperactivity Disorder

We examined trajectories of academic and social functioning in children with attention-deficit/hyperactivity disorder (ADHD) to identify those who might be at risk for especially severe levels of academic and social impairment over time. We estimated a series of growth mixture models using data from two subsamples of children participating in the NIMH Collaborative Multisite Multimodal Treatment Study of Children with ADHD (MTA) including those with at least baseline and 96-month data for reading and mathematics achievement (n = 392; 77.3% male; M age = 7.7; SD = 0.8) or social skills ratings from teachers (n = 259; 74.9% male; M age = 7.6; SD = 0.8). We compared latent trajectories for children with ADHD to mean observed trajectories obtained from a local normative (i.e., non-ADHD) comparison group (n = 289; 80.6% male; M age = 9.9; SD = 1.1). Results indicated six latent trajectory classes for reading and mathematics and four classes for teacher social skills ratings. There was not only a relationship between trajectories of inattention symptoms and academic impairment, but also a similarly strong association between trajectory classes of hyperactive-impulsive symptoms and achievement. Trajectory class membership correlated with socio-demographic and diagnostic characteristics, inattention and hyperactive-impulsive symptom trajectories, externalizing behavior in school, and treatment receipt and dosage. Although children with ADHD display substantial heterogeneity in their reading, math, and social skills growth trajectories, those with behavioral and socio-demographic disadvantages are especially likely to display severe levels of academic and social impairment over time. Evidence-based early screening and intervention that directly address academic and social impairments in elementary school-aged children with ADHD are warranted. The ClinicalTrials.gov identifier is NCT00000388.     

A Psychometric Evaluation of the Behavioral Inhibition Questionnaire in a Non-Clinical Sample of Israeli Children and Adolescents

This study examined the psychometric properties of a Hebrew version of the Behavioral Inhibition Questionnaire (BIQ) in a non-clinical sample of Israeli children and adolescents. We produced a Hebrew translation of the BIQ and collected 227 responses to it from parents of children aged 4–15. Some respondents in the larger sample also completed the Screen for Child Anxiety Related Emotional Disorders (SCARED) questionnaire (n?=?91) and the Conners’ Abbreviated Parent-Teacher (CONNERS) questionnaire (n?=?39), in addition to the BIQ. Lastly, 21 children of BIQ respondents (aged 8–14) completed a self-report version of the questionnaire. Confirmatory factor analysis (CFA) was performed to assess how well the established six correlated factor model of the BIQ applied to the sample data. The Hebrew BIQ demonstrated good internal consistency (Chronbach’s α?=?.94, n?=?227) and 3 month test–retest reliability, (r?=?.95, p?<?.001, n?=?21). It also showed both convergent validity, as scores on the BIQ were correlated with the SCARED (r?=?.66, p?<?.01. n?=?91), and discriminant validity, as BIQ scores were not correlated with the CONNERS (r?=?.24, n?=?39). Finally, mother reports of BI were significantly correlated to child reports of BI via the BIQ (r?=?.60, p?<?.01, n?=?21). Thus, through this preliminary study we demonstrated that the Hebrew version of the BIQ is an effective tool for screening for BI among Israeli children, making it a useful instrument for future research.     

Preventing Conduct Disorder and Callous Unemotional Traits: Preliminary Results of a School Based Pilot Training Program

This study investigated whether a school-based pilot prevention program is effective in reducing Conduct Disorder (CD) symptoms and callous unemotional (CU) traits (i.e., lack of empathy and guilt) in a community sample of children. A total of 304 children from three schools in Cyprus were randomly assigned at school level to either a prevention group that received a skill building training program (N = 94; M _age  = 7.91, SD = .74; 52.1% female) or a control group that received no training (N = 210; M _age  = 7.82, SD = .81; 50.5% female). To evaluate the effectiveness of the program, CD symptoms and CU traits were assessed before the implementation of the training program and at 3 and 9 months after training. Additionally, the child’s impulsivity, parental involvement and friend support were assessed pre- and post-prevention. Significant post-training reductions in CU traits were identified for the prevention, but not the control, group at both 3-month and 9-month follow-ups and in CD symptoms at the 9 month follow-up. Furthermore, children in the prevention group scored lower on impulsivity and higher on paternal involvement and friend support compared to the control group after participating in the training program. This study provides preliminary evidence that child focused training delivered in the school setting can provide lasting benefits by preventing the development of CU traits, impulsivity, and CD. The program was also successful in improving the child’s social relationships with peers and parents. These findings emphasize the importance of school based prevention efforts.
