THE GENERALIZATION EFFECTS OF PARENT TRAINING ACROSS STIMULUS SETTINGS

Five parents of nonverbal children were trained in two home settings to modify antecedents and consequences to their children's vocalizations. Generalization effects of the parent training on both the parent's and children's behaviors under different stimulus conditions were investigated using multiple-baseline designs. Increases in parent prompting and reinforcing their children's vocalizations generalized only minimally to a new setting in the home where parent training had not occurred. Child increases in vocalizations produced by the parents in the training settings did generalize to this new setting in the home. There was minimal generalization of child vocalizations to a free-play setting at school. In a formal speech session conducted by a behavior specialist at school, only one child showed definite increases in acquisition rate as a function of the parents starting to train the sound at home.     

视觉观点采择中自我中心性偏差的抑制和归因之争

自我中心性偏差是社交失败的重要原因,但其产生机制还存在争议。以往研究存在抑制性选择模型与流利性错误归因两种理论观点:前者认为对自身观点的抑制失败会导致自我中心性偏差;后者则认为错误地选择自身更为流畅的信息会导致自我中心性偏差。为整合上述争论,提出抑制-归因协同作用模型,认为抑制和归因两种加工或可共同导致自我中心性偏差。未来研究应借助精巧的研究范式和特殊被试群体,进一步验证该模型。     

自尊与人际互动：理论、研究与问题

基于自我确认理论开展的大量研究,有助于理解自尊对人际互动行为的调节作用。然而,研究者对自尊的测量工具不尽相同,筛选实验被试的标准也不尽一致,实验范式忽略了对实际人际互动情境的操纵,单纯采用人际选择反应作为测量自我确认的指标,因而难以形成具有整合性的理论模型。今后的研究有必要在编制合适的测量工具的基础上,将整体自尊与特殊自尊作为两个独立的变量置于整合性实验范式下开展研究,同时采用对人际评价信息的认知判断和对评价者的交往选择的双维指标,以全面揭示整体自尊与特殊自尊对自我确认过程的相对作用及其心理机制。     

Comparing Traditional and Ebook-Augmented Parent-Child Interaction Therapy (PCIT): A Randomized Control Trial of Pocket PCIT

Disruptive behavior in young children is one of the most common referrals to behavioral health providers. While numerous effective parenting programs, such as parent–child interaction therapy (PCIT), exist for improving children’s behaviors, challenges with treatment engagement and retention limit the intended positive impact on child and caregiver outcomes, particularly for racial and ethnic minority families. In an effort to address barriers contributing to poor engagement and retention in traditional PCIT service delivery and among ethnic and racial minority families, a multimedia PCIT ebook was developed and evaluated. In a sample of the general public that utilized the ebook, users were found to be more engaged in viewing embedded videos within the ebook that were related to expert skill explanations and skill demonstrations than caregiver testimonies. A randomized controlled trial was also conducted to evaluate the extent that the ebook + PCIT improved treatment engagement, retention, parenting skills, skill acquisition efficiency, and child behavior above and beyond traditional PCIT. Participating families were randomly assigned to either the traditional PCIT (n = 71) or ebook + PCIT (n = 107) group using an online random number generator. Forty-nine caregivers (traditional PCIT n = 24, ebook + PCIT n = 25) were excluded from analyses because they were lost to follow-up during the intervention. Families in both the traditional PCIT and ebook + PCIT groups demonstrated generally equivalent positive outcomes in treatment engagement (i.e., attendance, treatment length, completion rate) and caregiver skill acquisition efficiency at midtreatment, posttreatment, and 3-month follow-up. The addition of the ebook to PCIT also reduced child disruptive behavior at midtreatment, above and beyond traditional PCIT, but not at posttreatment or follow-up. Clinical implications and future directions are discussed.     

Parent-child interactions during joint engagement with touchscreen technology: A comparison of younger versus older toddlers

With a plethora of touchscreen apps aimed at young children, parents are receiving mixed messages about the appropriateness of such technology for their toddlers. The American Academy of Pediatrics (2016) advises limited engagement with digital media for this age group and encourages parents to co-engage with children when they are using screens. However, very little is known about parent-child interaction in the context of joint engagement with digital screen media in the toddler years. This study observed 56 toddlers (M = 32.5 months old; 53 % female) and a parent (52 mothers; 4 fathers) performing a 3-minute drawing task on a touchscreen tablet (digital condition), and on an Etch-A-Sketch (non-digital condition) using a repeated measures design. Observations were analysed using global ratings of dyadic interaction, comparing warmth, cooperation and conflict between digital and non-digital conditions. A mixed MANCOVA analysis, controlling for levels of daily usage of touchscreens, revealed lower levels of parent-child cooperation and warmth in the digital condition compared to the non-digital condition. In addition, there was a main effect of age with younger dyads displaying less cooperation overall, particularly in the digital condition where interactions were also less warm. Results suggest that co-engaging with digital technology can be a challenging and potentially emotionally charged context for both parents and young children. Younger toddlers, especially, may be more likely to experience less cooperative interactions when co-engaging with digital technology with a parent. Results are discussed in relation to developmental differences between 2- and 3-year olds, and the need for more nuanced guidance for parents supporting young children’s interaction with digital media.     

Temporal coordination between maternal looming and infant gaze in depressed and nondepressed dyads: A bootstrapping approach

In this study, we examine the convergent validity of a measure of maternal looming derived using a motion capture system, and the temporal coordination between maternal loom and infant gaze using an event-based bootstrapping procedure. The sample comprised 26 mothers diagnosed with postpartum depression, 43 nondepressed mothers, and their 4-month-old infants. Mother-infant interactions were recorded during a standard face-to-face setting using video cameras and a motion capture system. First, results showed that maternal looming was correlated with a globally coded measure of maternal overriding. Maternal overriding is an intrusive behavior occurring when the mother re-directs the infant’s attention to parent-led activities. Thus, this result confirms that maternal looming can be considered a spatial intrusion in early interactions. Second, results showed that compared to nondepressed dyads, depressed dyads were more likely to coordinate maternal loom and infant gaze in a Loom-in-Gaze-pattern. We discuss the use of automated measurement for analyzing mother-infant interactions, and how the Loom-in-Gaze pattern can be interpreted as a disturbance in infant self-regulation.     

COVID-19 and the Acceleration of Behavioral Parent Training Telehealth: Current Status and Future Directions

The SARS-COV-2 (COVID-19) pandemic and associated social distancing guidelines have accelerated the telehealth transition in mental health. For those providing Behavioral Parent Training (BPT), this transition has called for moving sessions that are traditionally clinic-based, active, and directive to engaging, supporting, and treating families of children with behavior disorders remotely in their homes. Whereas many difficulties accompany this transition, the lessons learned during the current public health crisis have the potential to transform BPT service delivery on a large scale in ways that address many of its long-standing limitations. We describe both challenges and opportunities and consider the possibilities inherent in a large scale BPT service delivery model capable of increasing the reach and impact of evidence-based treatment for all families.     

Using the teaching interaction procedure to train interventionists to implement the Cool versus Not CoolTM procedure

The teaching interaction procedure is a behavior analytic procedure that has been used to target the development of social skills. The teaching interaction procedure consists of labeling the target skill, providing a meaningful rationale, describing the steps of the target skill, modeling the skill, role‐play, and providing feedback throughout the interaction. Although the teaching interaction procedure has been used to teach a variety of social skills for individuals diagnosed with autism spectrum disorder (ASD), it has only been used to train staff in two studies. The purpose of this study was to evaluate the use of the teaching interaction procedure to teach three interventionists to implement the Cool versus Not Cool? procedure to target the development of social skills for children diagnosed with ASD. The results of a multiple baseline design demonstrated that the teaching interaction procedure was effective for all three interventionists. Results of the child participants' skill acquisition are also provided.     

Driver conflict response during supervised automation: Do hands on wheel matter?

Securing appropriate driver responses to conflicts is essential in automation that is not perfect (because the driver is needed as a fall-back for system limitations and failures). However, this is recognized as a major challenge in the human factors literature. Moreover, in-depth knowledge is lacking regarding mechanisms affecting the driver response process. The first aim of this study was to investigate how driver conflict response while using highly reliable (but not perfect) supervised automation differ for drivers that (a) crash or avoid a conflict object and (b) report high trust or low trust in automation to avoid the conflict object. The second aim was to understand the influence on the driver conflict response of two specific factors: a hands-on-wheel requirement (with vs. without), and the conflict object type (garbage bag vs. stationary vehicle). Seventy-six participants drove with highly reliable but supervised automation for 30 min on a test track. Thereafter they needed to avoid a static object that was revealed by a lead-vehicle cut-out. The driver conflict response was assessed through the response process: timepoints for driver surprise reaction, hands-on-wheel, driver steering, and driver braking. Crashers generally responded later in all actions of the response process compared to non-crashers. In fact, some crashers collided with the conflict object without even putting their hands on the wheel. Driver conflict response was independent of the hands-on-wheel requirement. High-trust drivers generally responded later than the low-trust drivers or not at all, and only high trust drivers crashed. The larger stationary vehicle triggered an earlier surprise reaction compared to the garbage bag, while hands-on-wheel and steering response were similar for the two conflict object types. To conclude, crashing is associated with a delay in all actions of the response process. In addition, driver conflict response does not change with a hands-on-wheel requirement but changes with trust-level and conflict object type. Simply holding the hands on the wheel is not sufficient to prevent collisions or elicit earlier responses. High trust in automation is associated with late response and crashing, whereas low trust is associated with appropriate driver response. A larger conflict object trigger earlier surprise reactions.     

Urgent and non-urgent takeovers during conditional automated driving on public roads: The impact of different training programmes

Supplying training to drivers that teaches them about automated driving and requests to intervene may help them to build and maintain a mental representation of how automation works and thereby improve takeover performance. We aimed to investigate the effect of different types of training programmes about the functioning of automated driving on drivers’ takeover performance during real driving. Fifty-two participants were split into three groups for training sessions: paper (short notice), video (3-minute tutorial) and practice (short drive). After the training, participants experienced automated driving and both urgent and non-urgent requests to intervene in a Wizard-of-Oz vehicle on public roads. Participants’ takeover time, visual behaviour, mental workload, and flow levels during the requests to intervene were assessed. Our results indicated that in urgent circumstances, participants’ takeover response times were faster in the practice training condition compared to the other training conditions. Nevertheless, the practice training session did not present any other positive effect on drivers’ visual behaviour. This could indicate that prior training, particularly when reinforcing drivers' motor skills, improved their takeover response time at the latest motor stages rather than in the early sensory states. In addition, the analysis of in-vehicle videos revealed that participants’ attention was captured in the first place by the in-vehicle human-machine interface during the urgent request to intervene. This highlights the importance for designers to display information on the HMI in an appropriate way to optimise drivers’ situation awareness in critical situations.
