Low Working Memory rather than ADHD Symptoms Predicts Poor Academic Achievement in School-Aged Children

This study examined whether working memory (WM), inattentive symptoms, and/or hyperactive/impulsive symptoms significantly contributed to academic, behavioral, and global functioning in 8-year-old children. One-hundred-sixty 8-year-old children (75.6% male), who were originally recruited as preschoolers, completed subtests from the Wechsler Intelligence Scale for Children–Fourth Edition, Integrated and Wechsler Individual Achievement Test–Second Edition to assess WM and academic achievement, respectively. Teachers rated children’s academic and behavioral functioning using the Vanderbilt Rating Scale. Global functioning, as rated by clinicians, was assessed by the Children’s Global Assessment Scale. Multiple linear regressions were completed to determine the extent to which WM (auditory-verbal and visual-spatial) and/or inattentive and hyperactive/impulsive symptom severity significantly contributed to academic, behavioral, and/or global functioning. Both auditory-verbal and visual-spatial WM but not ADHD symptom severity, significantly and independently contributed to measures of academic achievement (all p < 0.01). In contrast, both WM and inattention symptoms (p < 0.01), but not hyperactivity-impulsivity (p > 0.05) significantly contributed to teacher-ratings of academic functioning. Further, inattention and hyperactivity/impulsivity (p < 0.04), but not WM (p > 0.10) were significantly associated with teacher-ratings of behavioral functioning and clinician-ratings of global functioning. Taken together, it appears that WM in children may be uniquely related to academic skills, but not necessarily to overall behavioral functioning.     

Intra- and Inter-Individual Differences in Adolescent Depressive Mood: the Role of Relationships with Parents and Friends

Utilizing four waves of data from 1126 secondary school Dutch adolescents (Mage = 13.95 at the first wave; 53% boys), the current study examined the interplay between parent-adolescent and friend-adolescent relationship quality (satisfaction and conflict) in relation to adolescents’ depressive mood. Using multilevel analyses, the interacting effects of parent/friend relationship quality on depressive mood were tested at both the intra- and inter-individual level. Analyses at the intra-individual level investigated whether individual depressive mood fluctuated along with changes in their social relationships regardless of one’s general level of depressive mood; and analyses at the inter-individual level examined whether the average differences in depressive mood between adolescents were associated with different qualities of social relationships. We interpreted the patterns of interactions between parent and friend relationships using four theoretical models: the reinforcement, toxic friends, compensation, and additive model. The results demonstrate the covariation of parent- and friend- relationship quality with adolescents’ depressive mood, and highlight that parent and peer effects are not independent from each other—affirming the compensation and additive models at the intra-individual and the reinforcement and additive models at the inter-individual level. The findings highlight the robustness of the protective effects of parent and peer support and the deleterious effects of conflictual relationships for adolescent mental health. The results have implications for both the theoretical and practical design of (preventive) interventions aimed at decreasing adolescents’ depressive mood.     

Dynamic measures of anxiety-related threat bias: Links to stress reactivity

Exaggerated attention to threatening information, or the threat bias, has been implicated in the development and maintenance of anxiety disorders. Recent research has highlighted methodological limitations in threat bias measures, such as temporal insensitivity, leading to the development of novel metrics that capture change and variability in threat bias over time. These metrics, however, have rarely been examined in non-clinical samples. The present study aimed to explore the utility of these trial-level metrics in predicting anxiety-related stress reactivity (stress-induced negative mood state) in trait anxious adults (N?=?52). Following a stressor, participants completed the dot probe task to generate threat bias scores. Stress reactivity was measured via stress-induced changes in subjective mood state. More variability in trial-level bias scores (TL-BSs) and greater bias away from threat (both mean and peak negative TL-BSs) predicted increased stress reactivity. The temporal characteristics of threat bias and implications for clinically-relevant measurement are discussed.     

Motivated attention to fear-related stimuli: Evidence for the enhanced processing of fear in the late positive potential

Differences in the processing of emotions like fear and sadness have important implications for our understanding of many psychological phenomena (e.g., attentional biases, psychopathology). The late positive potential (LPP) is an established event-related potential that reflects motivated attention to emotional stimuli at the neural level with excellent temporal resolution, but has been infrequently used to study differences across emotions. Drawing on functional theories of emotion suggesting that the quick processing of fear-inducing stimuli increases chances of survival, we hypothesized that fear-inducing pictures would produce larger LPP amplitudes compared to other emotions (happy and sad) in the early time windows of the LPP (e.g., 400–700, 700–1000 ms). The results supported our hypothesis, offering new, albeit preliminary, evidence of the differential processing of threat-related stimuli on the LPP.     

Modeling Nonstationary Emotion Dynamics in Dyads using a Time-Varying Vector-Autoregressive Model

Emotion dynamics are likely to arise in an interpersonal context. Standard methods to study emotions in interpersonal interaction are limited because stationarity is assumed. This means that the dynamics, for example, time-lagged relations, are invariant across time periods. However, this is generally an unrealistic assumption. Whether caused by an external (e.g., divorce) or an internal (e.g., rumination) event, emotion dynamics are prone to change. The semi-parametric time-varying vector-autoregressive (TV-VAR) model is based on well-studied generalized additive models, implemented in the software R. The TV-VAR can explicitly model changes in temporal dependency without pre-existing knowledge about the nature of change. A simulation study is presented, showing that the TV-VAR model is superior to the standard time-invariant VAR model when the dynamics change over time. The TV-VAR model is applied to empirical data on daily feelings of positive affect (PA) from a single couple. Our analyses indicate reliable changes in the male’s emotion dynamics over time, but not in the female’s—which were not predicted by her own affect or that of her partner. This application illustrates the usefulness of using a TV-VAR model to detect changes in the dynamics in a system.     

Telehealth and in‐person training outcomes for novice discrete trial training therapists

The efficacy and efficiency of telehealth and in‐person training were compared while teaching seven undergraduate students to implement components of discrete trial training. A multiple‐baseline design across skills with elements of multiple probe and delayed multiple baseline combined with an alternating‐treatments design was used to evaluate the effects of behavioral skills training (BST) on (a) implementing a multiple stimulus without replacement preference assessment, (b) setting up an instructional context, (c) delivering antecedent prompts, and (d) delivering consequences for accurate and inaccurate responding. Two skills were trained via telehealth and two skills were trained in‐person using BST procedures with a mock student. All participants provided high acceptability ratings for both training procedures. Results also showed that telehealth training was as efficacious and efficient as in‐person training for all skills across all participants. Five of six participants showed high levels of maintenance of the newly acquired skills; these five also exhibited the skills during a novel instructional task.     

Project STARS (Studies on Trajectories of Adolescent Relationships and Sexuality): A longitudinal,multi-domain study on sexual development of Dutch adolescents

This study gives an overview of Project STARS (Studies on Trajectories of Adolescent Relationships and Sexuality), a four-wave longitudinal study of 1297 Dutch adolescents. First, the sample, measures and four sub-projects are described. Second, hierarchical regression analyses were conducted to examine how key variables from the individual domain (impulsivity), parent domain (parent–adolescent relationship quality), peer domain (involvement with peers) and media domain (time spent on social networking sites), and their interactions predict changes in the experience with sexual behaviour of adolescents across time. Results showed that higher levels of impulsivity, lower quality of relation with parents, more frequent involvement with peers and more time spent on social networking sites at baseline predicted increases in sexual experience of adolescents over a subsequent 1.5-year time period. No interaction effects among the domains were found. The findings highlight the significance of a multi-domain approach to the study of adolescent sexual development.     

Finding character strengths through loss: An extension of Peterson and Seligman (2003)

People can experience positive changes even in the midst of adversity and loss. We investigated character strengths following three recent shooting tragedies. Using an Internet database of respondents to the Values in Action Inventory of Strengths (VIA-IS), we compared responses from three groups of participants (N?=?31,429) within close proximity of each event: those who completed it eight months prior to the event, and one month and two months after. Results suggested that for one of the events, participants who completed the VIA-IS after the event showed slightly different levels of self-reported character strengths compared to participants who completed the VIA-IS before the event, with some mean levels higher and others lower. The observed differences in character strengths were inconsistent across follow-up periods, and effect sizes were small (d values from –0.13 to 0.15). These findings raise questions about whether and how tragedies might catalyze differences in character strengths.     

Body Dissatisfaction and Eating Disorder Symptomatology: A Latent Structural Equation Modeling Analysis of Moderating Variables in 18-to-28-Year-Old Males

ABSTRACT. Although body dissatisfaction is recognized as the strongest risk factor for eating disturbances, a majority of young males are body dissatisfied, but do not concomitantly report severe levels of eating disorder symptomatology. The present investigation was designed to examine five theoretically relevant variables (i.e., body checking, emotional dysregulation, perfectionism, insecure-anxious attachment, and self-esteem) as potential moderators of the relationship between body dissatisfaction and two critical components of male eating disorder symptomatology: drive for muscularity and bulimic behaviors. Data collected from 551 Italian males between 18 and 28 years old were analyzed using latent structural equation modeling. The authors found that emotional dysregulation, body checking, insecure-anxious attachment and perfectionism intensified the relationship between body dissatisfaction and each criterion variable representing male eating disorder symptomatology; the interactions accounted respectively for an additional 2%, 7%, 4% and 5% of variance in drive for muscularity and for an additional 6%, 4%, 5%, and 2% of the variance in bulimic behaviors. By contrast self-esteem weakened this relationship and the interactions accounted for an additional 3% of the variance in both drive for muscularity and bulimic behaviors. Implications of these findings for prevention and treatment of male eating disturbances are discussed.     

Increasing Awareness of Potentially Helpful Motivations and Techniques for Forgiveness

The authors examined 3 motives and 3 techniques for forgiveness to assess differences between people high or low in dispositional forgiveness (HDF and LDF, respectively). HDF participants rated all motives as more compelling and familiar than did LDF participants. Forgiveness being the right thing to do was rated as more persuasive and familiar; however, mental and physical health benefits were rated as compelling but less familiar forgiveness motives. LDF participants rated the various techniques as less familiar and more difficult compared with HDF participants. Overall, participants rated forgive and forget as the most familiar but most difficult technique to implement.
