On the relation between theory of mind and executive functioning: A developmental cognitive neuroscience perspective

Theory of mind (ToM) and executive functioning (EF) show marked interrelatedness across childhood, and developmental psychologists have long been interested in understanding the nature of this association. The present review addresses this issue from a cognitive neuroscience perspective by exploring three hypotheses regarding their functional overlap: (1) ToM relies on EF (EF→ToM); (2) EF relies on ToM (ToM→EF); and (3) ToM and EF are mutually related, owing to shared neural structures or networks (ToM?EF). Drawing on evidence from normative brain development, neurodevelopmental and neurodegenerative diseases, patient lesion studies, and brain-imaging studies, we suggest that only a strict version of the ToM?EF proposal of complete neural overlap can be confidently ruled out on the basis of existing evidence. The balance of evidence suggests that separable neurobiological mechanisms likely underlie ToM and EF, with shared mechanisms for domain-general processing that support both abilities. We highlight how future studies may empirically substantiate the nature of the ToM–EF relationship using various biobehavioral approaches.     

Spatial representation of magnitude in humans (<Emphasis Type="Italic">Homo sapiens</Emphasis>), Western lowland gorillas (<Emphasis Type="Italic">Gorilla gorilla gorilla</Emphasis>), and American black bears (<Emphasis Type="Italic">Ursus americanus</Emphasis>)

The spatial-numerical association of response codes (SNARC) effect is the tendency for humans to respond faster to relatively larger numbers on the left or right (or with the left or right hand) and faster to relatively smaller numbers on the other side. This effect seems to occur due to a spatial representation of magnitude either in occurrence with a number line (wherein participants respond to relatively larger numbers faster on the right), other representations such as clock faces (responses are reversed from number lines), or culturally specific reading directions, begging the question as to whether the effect may be limited to humans. Given that a SNARC effect has emerged via a quantity judgement task in Western lowland gorillas and orangutans (Gazes et al., Cog 168:312–319, 2017), we examined patterns of response on a quantity discrimination task in American black bears, Western lowland gorillas, and humans for evidence of a SNARC effect. We found limited evidence for SNARC effect in American black bears and Western lowland gorillas. Furthermore, humans were inconsistent in direction and strength of effects, emphasizing the importance of standardizing methodology and analyses when comparing SNARC effects between species. These data reveal the importance of collecting data with humans in analogous procedures when testing nonhumans for effects assumed to bepresent in humans.     

Automated respiratory sinus arrhythmia measurement: Demonstration using executive function assessment

Respiratory sinus arrhythmia (RSA) is a quantitative metric that reflects autonomic nervous system regulation and provides a physiological marker of attentional engagement that supports cognitive and affective regulatory processes. RSA can be added to executive function (EF) assessments with minimal participant burden because of the commercial availability of lightweight, wearable electrocardiogram (ECG) sensors. However, the inclusion of RSA data in large data collection efforts has been hindered by the time-intensive processing of RSA. In this study we evaluated the performance of an automated RSA-scoring method in the context of an EF study in preschool-aged children. The absolute differences in RSA across both scoring methods were small (mean RSA differences = –0.02–0.10), with little to no evidence of bias for the automated relative to the hand-scoring approach. Moreover, the relative rank-ordering of RSA across both scoring methods was strong (rs = .96–.99). Reliable changes in RSA from baseline to the EF task were highly similar across both scoring methods (96%–100% absolute agreement; Kappa = .83–1.0). On the basis of these findings, the automated RSA algorithm appears to be a suitable substitute for hand-scoring in the context of EF assessment.     

The Experience of Genetic Counselors Working with Patients Facing the Decision of Pregnancy Termination after 24 Weeks Gestation

Prenatal genetic counselors are health care professionals who counsel women making reproductive decisions which include decisions such as terminating pregnancies due to fetal anomalies. Little is known about the experiences and practices of prenatal genetic counselors working with women who have the option of termination after 24 weeks gestation. In this national survey of 168 genetic counselors who have practiced prenatal genetic counseling, we asked about their general practice patterns, including indications for which termination is offered and types of abortion care services that are coordinated by genetic counselors. We report respondents’ self-assessments of level of understanding of federal abortion law and abortion procedures. Seventy-six percent of respondents have offered and counseled on termination after 24 weeks and 93% of respondents believe it is the responsibility of the counselor to discuss this option with patients. However, one-third report that they have some or no understanding of the procedures and three-quarters report that they have some or no understanding of federal abortion law. The results of this study provide insight into knowledge and experiences of genetic counselors working with these patients, allowing for improved genetic counselor training and continuing education to provide better guidance and develop more effective means of assisting patients.     

The Name Game: How Naming Products Increases Psychological Ownership and Subsequent Consumer Evaluations

Naming products is quite prevalent in American culture; however, we are not aware of any consumer research that explores the effects of this phenomenon. Across three studies, we demonstrate that when consumers name products, their evaluations of those products increase (e.g., attitudes, purchase intentions, and willingness to accept). We find that name fit and creativity as well as subsequent psychological ownership drive this effect. We also demonstrate that the naming effect is quite robust—replicating across multiple products, presentation formats, and populations as well as persisting over time. These results contribute to consumer research by opening up a new substantive line of inquiry into the effects of naming products.     

Brief Counseling for Alcohol Misuse Among Trauma Patients: Two Interventions and Influence of Baseline Use

This study examined whether baseline trauma patient characteristics and randomized participation in 1 of 2 brief interventions predicted changes in alcohol use at 6 months postintervention. Higher total Alcohol Use Disorders Identification Test (AUDIT) scores predicted greater changes, and specific AUDIT items were significant predictors.     

Cross-Age Peer Tutoring and Fluency-Based Instruction to Achieve Fluency with Mathematics Computation Skills: A Randomized Controlled Trial

The current study employed a randomized controlled trial to evaluate the use of peer tutoring and fluency-based instruction to increase mathematics fluency with addition and subtraction computation skills. Forty-one elementary school students between the ages of eight and 12 years participated in the 8-week study using cross-age peer tutoring, Say All Fast Minute Every Day Shuffled, frequency building, and the morningside math facts curriculum (Johnson in Morningside mathematics fluency: math facts (vol 1–6; curriculum program), Morningside Press, Seattle, 2008). Pre- and post-test measures of mathematics fluency and calculation were conducted with all participants. A measure of social skills and competing problem behaviors was also conducted at pre- and post-testing to evaluate any additional effects of the peer tutoring model. The results demonstrated a statistically significant difference between groups on measures of mathematics fluency, with the experimental group demonstrating significantly higher scores than the control group at post-testing. There were no significant differences between groups on measures of social skills and competing problem behaviors or calculation. The findings indicate that cross-age peer tutoring and fluency-based instruction resulted in positive outcomes for tutees in the mathematics domain, specifically mathematics fluency.     

Father Involvement and Behavior Problems among Preadolescents at Risk of Maltreatment

Although there is a well-established connection between father involvement and children’s positive behavioral development in general, this relation has been understudied in more vulnerable and high-risk populations. The aims of this study were to examine how the quantity (i.e., the amount of shared activities) and quality (i.e., perceived quality of the father-child relationship) of father involvement are differently related to internalizing and externalizing behavior problems among preadolescents at risk of maltreatment and test if these associations are moderated by father type and child maltreatment. A secondary data analysis was conducted using data from the Longitudinal Studies of Child Abuse and Neglect (LONGSCAN). Generalized estimating equations analysis was performed on a sample of 499 preadolescents aged 12 years. The results indicated that higher quality of father involvement was associated with lower levels of internalizing and externalizing behavior problems whereas greater quantity of father involvement was associated with higher levels of internalizing and externalizing behavior problems. The positive association between the quantity of father involvement and behavior problems was stronger in adolescents who were physically abused by their father. The association between father involvement and behavior problems did not differ by the type of father co-residing in the home. The findings suggest that policies and interventions aimed at improving the quality of fathers’ relationships and involvement with their children may be helpful in reducing behavior problems in adolescents at risk of maltreatment.     

A psychometric comparison of anxiety-relevant attention measures

Background and Objectives: Preferential attention to threat, emotional response inhibition, and attentional control each purportedly play a key role in anxiety disorders. Divergent psychometric properties among attention measures may produce differential detection of anxiety-related associations and treatment-related changes. However, no studies have directly compared the psychometric properties of these attention measures in the same sample.

Design: Eighty-five young adults (M?=?19.41 years, SD?=?1.47, 48 Females) completed a cognitive task battery and a subset of 60 participants (M?=?19.42 years, SD?=?1.48, 33 Females) completed the task battery again approximately two weeks later.

Method: To assess preferential attention to threat, emotional response inhibition, and attentional control, the cognitive task battery included a dot-probe task, emotion and gender Stroop tasks, and a flanker task. Tasks varied in how attention was directed and if emotional stimuli were included. Internal consistency and test-retest reliability were compared across measures.

Results: Within the same sample, internal consistency and reliability differed across attention measures. Explicit attention measures (emotional Stroop and flanker) exhibited stronger internal consistency and greater test-retest reliability compared to implicit measures (dot-probe and gender Stroop).

Conclusions: These results inform clinical research using attention measures to assess anxiety-related differences and treatment response.     

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.
