Peer tutoring to prevent firearm play acquisition, generalization, and long-term maintenance of safety skills

Hundreds of accidental injuries and deaths to children occur annually in the United States as a result of firearm play. Behavioral skills training (BST) and in situ training have been found to be effective in teaching children the skills to use if they find a firearm, but training requires substantial time and effort. The current study examined the use of peers as tutors as a potential way to decrease the time and resources needed to teach these safety skills to youngsters. Peer trainers conducted BST and in situ training with other children. Children taught by the peer trainers acquired the safety skills and demonstrated them in naturalistic situations in which the skills were needed. Furthermore, all of the peer trainers acquired and maintained the skills. These results support the use of peer tutoring for teaching safety skills to other children.     

An evaluation of in situ training to teach sexual abuse prevention skills to women with mental retardation

The current study evaluated a behavioral skills training (BST) program in combination with in situ training to teach sexual abuse prevention skills to five women with mild to moderate mental retardation. In situ assessments were conducted following BST and in situ training sessions were conducted for those who were unable to demonstrate the skills in the natural setting. The results showed that generalization of the safety skills to the natural setting occurred for three of the five participants following one to two in situ training sessions. One participant required 12 in situ training sessions and three booster training sessions to reach criterion level. Three of four participants assessed 1 month following training maintained the skills. Copyright © 2007 John Wiley & Sons, Ltd.     

Co-Sleeping among School-Aged Anxious and Non-Anxious Children: Associations with Sleep Variability and Timing

Little is known about the co-sleeping behaviors of school-aged children, particularly among anxious youth who commonly present for the treatment of sleep problems. The current study examined the occurrence of co-sleeping in both healthy and clinically anxious children and its associated sleep patterns. A total of 113 children (ages 6–12), 75 with primary generalized anxiety disorder and 38 healthy controls, participated along with their primary caregiver. Families completed structured diagnostic assessments, and parents reported on their child’s co-sleeping behaviors and anxiety severity. Children provided reports of anxiety severity and completed one week of wrist-based actigraphy to assess objective sleep patterns. A significantly greater proportion of anxious youth compared to healthy children co-slept, and greater anxiety severity was related to more frequent co-sleeping. Co-sleeping in anxious youth was associated with a delay in sleep timing and with greater sleep variability (i.e., more variable nightly sleep duration). All analyses controlled for child age, race/ethnicity, family income, and parental marital status. Co-sleeping is highly common in anxious school-aged children, with more than 1 in 3 found to co-sleep at least sometimes (2–4 times a week). Co-sleeping was even more common for youth with greater anxiety severity. Increased dependence on others to initiate and maintain sleep may contribute to poorer sleep in this population via shifted schedules and more variable sleep patterns.     

Multimedia Field Test: Digitalizing Better Sleep Using the Sleepio Program

The promise of online cognitive behavioral therapy for insomnia (CBT-I) and other sleep-related problems as an alternative to traditional face-to-face treatment rests upon the accessibility, ease-of-use, and effectiveness of these approaches. Here we provide a review of Sleepio, a digitalized, state-of-the-art CBT-I program for adults, informed by our personal experience with the program, available research, and information provided at the Sleepio website. The 6-week treatment program can be completed flexibly via web-based or mobile platform. Initial assessment of individual goals and baseline sleep patterns is used to build a personalized account comprised of four sections: Sleep Diary, Case File, Library, and Community. Sleepio uses evidence-based principles and practices, engaging content, and an easy-to-follow format. Unique features of the program including synchronization with compatible sleep tracking devices, multiple built-in user supports, and a 14-day money-back guarantee. Both statistical and clinically meaningful sleep improvements have been found in a large randomized controlled trial. Overall, Sleepio represents a model program for online CBT-I delivery.     

Semantic priming effects in a lexical decision task: comparing third graders and college students in two different stimulus onset asynchronies

Differences in the semantic priming effect comparing child and adult performance have been found by some studies. However, these differences are not well established, mostly because of the variety of methods used by researchers around the world. One of the main issues concerns the absence of semantic priming effects on children at stimulus onset asynchrony (SOA) smaller than 300ms. The aim of this study was to compare the semantic priming effect between third graders and college students at two different SOAs: 250ms and 500ms. Participants performed lexical decisions to targets which were preceded by semantic related or unrelated primes. Semantic priming effects were found at both SOAs in the third graders' group and in college students. Despite the fact that there was no difference between groups in the magnitude of semantic priming effects when SOA was 250ms, at the 500ms SOA their magnitude was bigger in children, corroborating previous studies. Hypotheses which could explain the presence of semantic priming effects in children's performance when SOA was 250ms are discussed, as well as hypotheses for the larger magnitude of semantic priming effects in children when SOA was 500ms.     

Flexible attention allocation to visual and auditory working memory tasks: manipulating reward induces a trade-off

Prominent roles for general attention resources are posited in many models of working memory, but the manner in which these can be allocated differs between models or is not sufficiently specified. We varied the payoffs for correct responses in two temporally-overlapping recognition tasks, a visual array comparison task and a tone sequence comparison task. In the critical conditions, an increase in reward for one task corresponded to a decrease in reward for the concurrent task, but memory load remained constant. Our results show patterns of interference consistent with a trade-off between the tasks, suggesting that a shared resource can be flexibly divided, rather than only fully allotted to either of the tasks. Our findings support a role for a domain-general resource in models of working memory, and furthermore suggest that this resource is flexibly divisible.     

The development of cynicism

Two experiments explored the development of cynicism by examining how children evaluate other people who make claims consistent or inconsistent with their self-interests. In Experiment 1, kindergartners, second graders, and fourth graders heard stories with ambiguous conclusions in which characters made statements that were aligned either with or against self-interest. Older children took into account the self-interests of characters in determining how much to believe them: They discounted statements aligned with self-interest, whereas they accepted statements going against self-interest. Experiment 2 examined children's endorsement of three different explanations for potentially self-interested statements: lies, biases, and mistakes. Like adults, sixth graders endorsed lies and bias as plausible explanations for wrong statements aligned with self-interest; younger children did not endorse bias. Implications for the development of cynicism and children's understanding of bias are discussed.
