Neuro Clips:

Scarring effects of primary-grade retention?
Summary: A recent study found that retaining a child during the early primary school years lends toward a reduction in the chances of completing high school. The results suggest that this reduction is as high as a 60% reduced odds of completing school. The researchers suggest that these findings implied a scarring effect of early retention. Further research is needed to examine the underlying impacts of retaining children and how they may relate to educational practice.

Conflictive animations support the development of programming skills
Summary: In a recent study of conflictive animations, researchers found that they can be useful in teaching students computer programming. “Conflictive animations” relates to animations that have errors in them intentionally. These errors increase student engagement as they challenge them cognitively. The research findings suggest the instruction benefits of conflictive animations. Further research is needed to explore the usability of these animations for other instructional domains and also to explore through which mechanisms learning is being facilitated.

ADHD: Brains not recognizing angry expressions
Summary: Researchers explored the neural basis for facial expression recognition in children with ADHD compared to typically developing children. The findings demonstrate that children with ADHD display less of a response to angry expressions. The results suggest that this impaired recognition of angry faces may lend toward how children with ADHD interact with others. This has implications for practice in terms of how to help students with ADHD foster peer relationships.

Brain scans reveal 'gray matter' differences in media multitaskers
Summary: In a recent study of the simultaneous use of mobile phones, laptops, and other media devices researchers examined the brain structures of adults to compare them based on their self-reported use of those devices. The results demonstrate that the adults that reported greater multitasking with media devices had less grey matter density in the anterior cingulate cortex (ACC). The ACC is the part of the brain responsible for several cognitive and emotional functions. Further research is needed to explore this link in order to understand causal relationships as well as to determine how media multitasking relates to function in domains controlled by the ACC. Although the study was conducted on adults, it could have implications for children as they are exposed to media stimulation through various devices.

Higher risk of autism found in children born at short and long interpregnancy intervals
Summary: Researchers examined national registries to compare the incidence of autism relative to the spacing of pregnancies between siblings. The study found that children conceived less than 12 months apart from their siblings were at a heightened risk for autism diagnosis. Children conceived 5-10 years apart were at a 30% greater risk and those more than 10 years apart were at a 40% greater risk. These results could be indicative of factors associated with autism risk and have implications for further research.
Infant cooing, babbling linked to hearing ability, researcher finds
Summary: In a recent study of infant vocalizations, researchers compared the amount of vocalizations of infants with hearing loss compared to hearing infants. Vocalizations include cooing and babbling. The results indicate that hearing infants expressed more vocalizations than those with hearing loss. The infants with hearing loss expressed more vocalizations following cochlear implants. These results suggest that infant vocalizations are motivated by their ability to hear themselves. These findings could have implications for future study of the language development process.

Classroom intervention helps shy kids learn
Summary: INSIGHTS is an intervention that helps match students’ individual personalities with a supportive environment. A recent study explored the utility and usefulness of this intervention to support the needs of students based on their temperament. The results demonstrated that children with shy temperament experienced greater academic gains improving their critical thinking skills and math skills. These results have implications for potential application in other classroom environments. The results are of particular significance as shy children are often difficult to engage in the classroom setting and often suffer academically as well as socially.

Brainwave test could improve autism diagnosis, classification
Summary: A recent study measured brainwave patterns to examine the speed of sensory processing in children with autism spectrum disorder. The results suggest correlations between varying speeds of processing to audio-visual signals relative to severity of autism spectrum disorder. These findings have potential implications for the utilization of EEG testing to diagnose autism and to determine anticipated level of severity. Additionally, the findings have implications for therapeutic strategies for different levels of severity. Further investigation is necessary to better understand how autism impacts these mechanisms.

Narrow focus on physical activity could be ruining kids' playtime

Summary: Researchers conducted interviews with children 7-11 years of age to better understand their perspective of “playtime”. The interviews revealed that play represents a time to have fun with no anticipated outcome. The four commons themes were: 1) play is for fun 2) play doesn’t have to be active 3) there is little free-time for play and 4) taking risks makes play better. These four components contradict public health efforts to promote exercise and physical activity for youth. These findings have implications for how to alter public health messages and for how to promote unstructured playtime for youth.
