Summary
This study investigated discriminatory tendencies in autistic and neurotypical individuals. Researchers found no significant differences in discrimination between the two groups, suggesting complex factors influence these behaviors.
Area of Science:
- Neuroscience
- Social Psychology
- Developmental Psychology
Background:
- Autistic individuals often exhibit reduced social biases compared to neurotypical individuals.
- However, their discriminatory tendencies remain unclear, necessitating further investigation.
Purpose of the Study:
- To examine and compare discriminatory tendencies in autistic and neurotypical participants.
- To explore discrimination based on individual differences versus group affiliations.
Main Methods:
- Utilized the minimal group paradigm and a novel 'sheer difference' paradigm.
- Recruited 75 autistic and 75 neurotypical participants (total 150).
- Participants assigned points based on shared/different coin toss outcomes (individual) or group membership (group).
Main Results:
- Discriminatory tendencies were observed at both individual and group levels.
- No clear differences in discriminatory tendencies were found between autistic and neurotypical participants.
Conclusions:
- Discrimination can arise from both individual and group-based differences.
- The findings challenge simplistic views of discrimination in autism and neurotypical populations.
- Further research is needed to fully understand the nuances of discrimination and autism.

2.0K
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.

Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

McNemar's Test is a nonparametric statistical test used to determine if there is a significant difference in proportions between two related groups when the outcome is binary (e.g., yes/no, success/failure). It is beneficial when we have paired data, such as pre-test/post-test designs, where the same subjects are measured under two different conditions. The test is named after the statistician Quinn McNemar, who introduced it in 1947. It is commonly used in situations where subjects are...
