These findings refine the conceptualisation of social-cognitive processes across autistic traits while highlighting the importance of large samples for validating null effects.
🧠 What makes threat memories so hard to forget? 🐍😱
Using focused ultrasound we provide causal evidence that the human amygdala drives rapid threat learning 🐍⚡ and determines how resistant those memories become to subsequent extinction 🐍🚫

What roles do #brain regions play in disruption of action control by #Pavlovian biases? @johalgermissen.bsky.social @efouragnan.bsky.social &co show that anterior #insula stimulation reduces learning bias, while #dACC stimulation increases perseveration bias @plosbiology.org 🧪 plos.io/4tfY8nu
In a new preprint w/ @tianqizhan.bsky.social & @smfleming.bsky.social, we developed a new measure of metacognitive bias (over/under confidence in individual decisions)!
doi.org/10.31234/osf...
We replicated the self-bias and effects of social basis function use across four experiments. These effects also tracked meaningful social-cognitive computations, with social basis function use increasing as the percentage of group decisions increases.

We also observed the expected relationships between autistic traits and mental health questionnaire measures. For example, autistic trait scores were negatively correlated with cognitive empathy, but not affective empathy. These findings support the validity of the questionnaire measures.
😀Excited to share the new preprint!!!🥳
We show preserved self–other integration in social decision-making among individuals with elevated autistic traits (N = 1,621), highlighting the importance of large samples to validate null effects.

However, we found strong evidence for the absence of relationships between autistic trait scores and both self-bias (BF01 = 32.13) and social basis function use (BF01 = 7.04), indicating preserved self–other integration during social decision-making.
We used the well-established social group paradigm (www.nature.com/articles/s41...), developed by @mkwittmann.bsky.social, to distil precisely controlled measures of self-bias and social basis function use as two indices of self-other integration.
