Insights

Cognitive control impacts social outcomes in children with traumatic brain injury (TBI) and orthopaedic injury (OI). Lower socioeconomic status (SES) may amplify these effects, suggesting potential benefits from cognitive training.

Area of Science:

  • Neuroscience
  • Developmental Psychology
  • Pediatric Rehabilitation

Background:

  • Children with traumatic brain injury (TBI) and orthopaedic injury (OI) often experience social difficulties.
  • Cognitive control, encompassing executive functions like working memory and inhibitory control, is crucial for adaptive functioning.
  • The relationship between cognitive control and social outcomes in pediatric injury populations requires further elucidation.

Purpose of the Study:

  • To investigate the association between cognitive control abilities and social outcomes in children with moderate-to-severe TBI and OI.
  • To examine the moderating role of socioeconomic status (SES) on the cognitive control-social outcome relationship.

Main Methods:

  • Cross-sectional analysis of 12-month post-injury data from 52 children (7-17 years) with TBI and 41 children with OI.
  • Cognitive control assessed using the Sternberg Task (working memory) and the Flanker Task (inhibitory control).
  • Social outcome measured via the Vineland Adaptive Behavioural Scales (Socialization and Communications domains).

Main Results:

  • Slower reaction times on the Sternberg task were linked to poorer social outcomes, particularly in children from lower SES backgrounds.
  • Both baseline and interference reaction times on the Flanker task correlated with social outcomes.
  • The association between interference reaction time and social outcome was more pronounced in children with lower SES.

Conclusions:

  • Cognitive control is significantly related to social outcomes in children following TBI and OI.
  • Findings suggest that interventions targeting cognitive control may improve social functioning by enhancing social information processing.
  • The influence of SES highlights the need for tailored support for vulnerable pediatric populations.

Autism Spectrum Disorder01:19

Autism Spectrum Disorder

Autism spectrum disorder (ASD) is a neurodevelopmental condition marked by persistent deficits in social communication and interaction alongside restrictive and repetitive behaviors or interests. ASD is sometimes accompanied by intellectual impairment.
These core symptoms manifest differently among individuals, ranging from mild to severe. The disorder's complexity extends beyond its clinical presentation, encompassing a diverse range of biological, cognitive, and sociocultural influences.
Operant Conditioning Intervention01:24

Operant Conditioning Intervention

Operant conditioning serves as a foundational principle in therapeutic interventions aimed at modifying maladaptive behaviors. Central to this approach is the notion that behaviors, both adaptive and maladaptive, are learned through reinforcement. By analyzing the environmental factors that reinforce problematic behaviors, clinicians can design interventions to weaken these reinforcements and replace maladaptive behaviors with healthier alternatives.
In operant conditioning, behaviors that are...
Information Processing Approach01:30

Information Processing Approach

The information-processing theory of cognitive development centers on fundamental mental processes, including attention, memory, and problem-solving skills. Researchers in this field examine how cognitive abilities, such as working memory, evolve and influence children's overall development. Studies indicate that children with stronger working memory tend to excel in reading comprehension, math, and problem-solving compared to peers with less efficient memory skills. Low working memory is also...
Social Cognitive Perspective on Personality01:30

Social Cognitive Perspective on Personality

Social cognitive perspectives on personality emphasize the importance of conscious awareness, beliefs, expectations, and goals in shaping behavior. These perspectives incorporate behaviorist principles, such as learning through reinforcement and conditioning, but extend beyond them by highlighting human reasoning and planning. Unlike traditional behaviorist views, social cognitive theory focuses on how individuals reflect on their past experiences and plan for future outcomes by considering...

Social Foundations of Self II: The Generalized Other

According to George Herbert Mead, as children progress beyond the game stage, they develop a more comprehensive understanding of societal rules and norms. This cognitive and social development enables them to internalize the expectations of the broader community, refining their ability to regulate behavior.Consistent participation in organized activities is crucial in helping children recognize that their actions are not isolated but contribute to a more significant, interconnected group effort.

Causes of Social Behavior II: Cognitive Processes

Cognitive processes affect social behavior by guiding how individuals perceive, interpret, and respond to social stimuli. These mental processes enable individuals to assess others' behaviors, attribute causes to their actions, and form expectations based on past experiences.Causes of Behavior and Social JudgmentsIndividuals determine the causes of others' behaviors by distinguishing between personal traits and external circumstances. For example, if a friend frequently arrives late, an...
