Parent coaching at 6 and 10 months improves language outcomes at 14 months: A randomized controlled trial

Previous studies reveal an association between particular features of parental language input and advances in children's language learning. However, it is not known whether parent coaching aimed to enhance specific input components would (a) successfully increase these components in parents' language input and (b) result in concurrent increases in children's language development. The present randomized controlled trial assigned families of typically developing 6‐month‐old infants to Intervention (parent coaching) and Control (no coaching) groups. Families were equivalent on socioeconomic status, infants' gender, and infants' age. Parent coaching took place when infants were 6 and 10 months of age, and included quantitative and qualitative linguistic feedback on the amount of child‐directed speech, back‐and‐forth interactions, and parentese speech style. These variables were derived from each family's first‐person LENA recordings at home. Input variables and infant language were measured at 6, 10, and 14 months. Parent coaching significantly enhanced language input as measured by two social interaction variables: percentage of speech directed to the child and percentage of parentese speech. These two variables were correlated, and were both related to growth in infant babbling between 6 and 14 months. Intervention infants showed greater growth in babbling than Control infants. Furthermore, at 14 months, Intervention infants produced significantly more words than Control infants, as indicated by LENA recordings and parent report via the MacArthur‐Bates Communicative Developmental Inventory. Together, these results indicate that parent coaching can enrich specific aspects of parental language input, and can immediately and positively impact child language outcomes.

Habituation and novelty detection fNIRS brain responses in 5‐ and 8‐month‐old infants: The Gambia and UK

The first 1,000 days of life are a critical window of vulnerability to exposure to socioeconomic and health challenges (i.e. poverty/undernutrition). The Brain Imaging for Global Health (BRIGHT) project has been established to deliver longitudinal measures of brain development from 0 to 24 months in UK and Gambian infants and to assess the impact of early adversity. Here results from the Habituation‐Novelty Detection (HaND) functional near‐infrared spectroscopy (fNIRS) task at 5 and 8 months are presented (N = 62 UK; N = 115 Gambia). In the UK cohort distinct patterns of habituation and recovery of response to novelty are seen, becoming more robust from 5 to 8 months of age. In The Gambia, an attenuated habituation response is evident: a larger number of trials are required before the response sufficiently suppresses relative to the response during the first presented trials. Furthermore, recovery of response to novelty is not evident at 5 or 8 months of age. As this longitudinal study continues in The Gambia, the parallel collection of socioeconomic, caregiving, health and nutrition data will allow us to stratify how individual trajectories of habituation and recovery of response to novelty associate with different risk factors and adaptive mechanisms in greater depth. Given the increasing interest in the use of neuroimaging methods within global neurocognitive developmental studies, this study provides a novel cross‐culturally appropriate paradigm for the study of brain responses associated with attention and learning mechanisms across early development.     

Effects of Intensive Behavioral Treatment for Children With Varying Levels of Conduct Problems and Callous-Unemotional Traits

The purpose of this study was to examine whether callous–unemotional (CU) traits moderated the effects of intensive behavior therapy in elementary school-age children with varying levels of conduct problems (CP). Both treatment response (magnitude of change between pre- and posttreatment) and treatment outcomes (likelihood of normalization from treatment) were examined. Participants were 67 children (n = 49 boys, M_age = 9.6 years) with varying levels of CP and CU who participated in an intensive 8-week summer treatment program (STP) in which behavior therapy was delivered to children in recreational and classroom settings and to parents via weekly parent training sessions. Effects of treatment were measured using parent and teacher ratings of oppositional defiant disorder (ODD), conduct disorder (CD), callous behavior, and impairment. Results showed that CU moderated treatment effects for CD and callous behavior but not ODD or impairment. The moderating effects showed some evidence that participants with high CP and high CU before treatment had better treatment responses (larger change between pre- and posttreatment) but worse treatment outcomes (lower likelihood of normalization after treatment). These results suggest that intensive treatment, such as the STP, may be necessary but not sufficient for children with CP and CU traits.     

Daily Posttraumatic Stress Disorder Symptom Accommodation and Relationship Functioning in Military Couples

Romantic partners’ accommodation of trauma survivors’ posttraumatic stress disorder (PTSD) symptoms (e.g., taking on tasks, survivors avoid participating in social withdrawal) is associated with lower relationship satisfaction for both partners and survivors. Little is known about associations of partner accommodation with other aspects of relationship functioning, like intimacy. Sixty‐four male military veterans with at least subclinical PTSD and their partners participated in a 2‐week daily diary study. Veterans completed nightly measures of PTSD symptoms, while female partners completed nightly measures of accommodating behaviors performed that day. Both partners reported feelings of intimacy each night. Multilevel models revealed that accommodation was significantly, negatively associated with feelings of intimacy, with stronger effects for partners (t = ?8.70) than for veterans (t = ?5.40), and stronger effects when veterans had lower (t = ?7.43) rather than higher (t = ?5.20) levels of daily PTSD symptoms. Therapists should consider accommodating behaviors as a potential impediment to relationship intimacy, particularly when veterans have less severe symptoms of PTSD. Accommodating behaviors are an ideal treatment target in behavioral couple therapies.     

Brief report: Attentional Control Moderates the Relationship Between Attentional Bias and Anxiety in Children

This current study tested whether attentional control moderates the relationship between attentional bias to threat and anxiety in children. Children completed a self-report measure of attentional control and anxiety and an attentional bias task. Attentional control was examined as a moderator in the relationship between attentional bias and different dimensions of anxiety. The interaction between attentional control and attentional bias was significant for total and generalized anxiety. Although attentional control significantly moderated the relationship between attentional bias and anxiety, the direction of the interaction was not consistent with existing literature. Study implications and explanations for the study results are discussed.     

Differentiating factitious psychological presentations from malingering: Implications for forensic practice

Practitioners and researchers have long been challenged with identifying deceptive response styles in forensic contexts, particularly when differentiating malingering from factitious presentations. The origins and the development of factitious disorders as a diagnostic classification are discussed, as well as the many challenges and limitations present with the current diagnostic conceptualization. As an alternative to a formal diagnosis, forensic practitioners may choose to consider most factitious psychological presentations (FPPs) as a dimensional construct that are classified like malingering as a V code. Building on Rogers' central motivations for malingering, the current article provides four explanatory models for FPPs; three of these parallel malingering (pathogenic, criminological, and adaptational) but differ in their central features. In addition, the nurturance model stresses how patients with FPPs attempt to use their relationship with treating professionals to fulfill their unmet psychological needs. Relying on these models, practical guidelines are recommended for evaluating FPPs in a forensic context.     

Justice at any cost? The impact of cost–benefit salience on criminal punishment judgments

This study investigated the effect of cost–benefit salience on simulated criminal punishment judgments. In two vignette‐based survey experiments, we sought to identify how the salience of decision costs influences laypeople's punishment judgments. In both experiments (N₁ = 109; N₂ = 398), undergraduate participants made sentencing judgments with and without explicit information about the direct, material costs of incarceration. Using a within‐subjects design, Experiment 1 revealed that increasing the salience of incarceration costs mitigated punishments. However, when costs were not made salient, punishments were no lower than those made when the costs were externalized (i.e., paid by a third party). Experiment 2 showed the same pattern using a between‐subjects design. We conclude that, when laypeople formulate sentencing attitudes without exposure to the costs of the punishment, they are prone to discount those costs, behaving as if punishment is societally cost‐free. However, when cost information is salient, they utilize it, suggesting the operation of a genuine, albeit labile, punishment preference. We discuss the implications of these findings for psychological theories of decision making and for sentencing policy, including the degree of transparency about the relevant costs of incarceration during the decision process.     

Social learning of nut-cracking behavior in East African sanctuary-living chimpanzees (Pan troglodytes schweinfurthii)

Nut cracking is restricted to communities of wild chimpanzees living in West Africa, suggesting it is an example of a socially transmitted tradition. Detailed study of the acquisition of nut cracking in wild chimpanzees is consistent with this conclusion. However, only 2, small-scale experiments have been carried out in captivity to explore the role of social transmission in the acquisition of this behavior. The study presented here does this with a comparatively larger, statistically viable sample of 11 sanctuary-living chimpanzees (Pan troglodytes schweinfurthii), permitting both between- and within-subjects experimental manipulations. Results confirmed that nut cracking can be acquired in a matter of days by social learning, but only in chimpanzees 3 to 4 years old and older. Direct comparisons are made with a study carried out in the wild, revealing striking similarities in developmental profiles.
