Summary
This summary is machine-generated.Perceived stigma in children affected by parental HIV/AIDS is linked to brain structure changes. The parahippocampal gyrus volume mediates the effect of stigma on aggressive behavior, supporting the stress acceleration hypothesis.
Area Of Science
- Neuroscience
- Developmental Psychology
- Public Health
Background
- Perceived stigma negatively impacts behavioral outcomes in children.
- The neurobiological underpinnings of stigma processing and its link to aggression in children affected by parental HIV/AIDS are not well understood.
Purpose Of The Study
- To investigate the neurobiological basis of perceived stigma.
- To examine the neural mechanisms linking perceived stigma to aggressive behavior in children affected by parental HIV/AIDS.
Main Methods
- 112 children (10-17 years) affected by parental HIV/AIDS were studied.
- Gray matter volume (GMV) in the prefrontal cortex and medial temporal lobe was analyzed.
- Correlation and mediation analyses were performed to assess relationships between brain structure, stigma, and aggression.
Main Results
- A significant positive correlation was found between parahippocampal gyrus volume and perceived stigma.
- Perceived stigma mediated the association between parahippocampal gyrus GMV and aggressive behavior.
Conclusions
- Findings suggest that perceived stigma influences aggressive behavior through alterations in the parahippocampal gyrus.
- Results support the stress acceleration hypothesis, indicating accelerated neurodevelopment in stress/emotion regions due to chronic stress.
- The study offers neurostructural insights for interventions targeting children affected by parental HIV/AIDS and other marginalized groups.

A modern form of aggression is bullying. As you learn in your study of child development, socializing and playing with other children is beneficial for children’s psychological development. However, as you may have experienced as a child, not all play behavior has positive outcomes. Some children are aggressive and want to play roughly. Other children are selfish and do not want to share toys. One form of negative social interactions among children that has become a national concern is...
Human genetics provides a profound framework for understanding the interplay between genetic predispositions and human psychology. At the heart of this discipline lies the study of how genes influence physical traits, behaviors, and susceptibility to diseases. Each person carries a unique genetic code that subtly or significantly shapes their psychological and behavioral landscape.
The complex relationship between genetics and psychology is observable through common biological components such...
Humans engage in aggression when they seek to cause harm or pain to another person. Aggression takes two forms depending on one’s motives: hostile or instrumental. Hostile aggression is motivated by feelings of anger with intent to cause pain; a fight in a bar with a stranger is an example of hostile aggression. In contrast, instrumental aggression is motivated by achieving a goal and does not necessarily involve intent to cause pain (Berkowitz, 1993); a contract killer who murders for...
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....
Social behavior is a complex phenomenon that arises from the interaction between biological predispositions and environmental influences. This intricate interplay shapes how individuals think, feel, and act in various social contexts. Understanding these mechanisms requires insights from psychology, neuroscience, genetics, and evolutionary theory.Environmental Influences on Social BehaviorEnvironmental factors, including temperature, odors, and visual stimuli, play a crucial role in shaping...
