We added a threshold level pitch shift to auditory feedback during vocalization. When participants reported not noticing the pitch shit, they still initiated a correction to their vocalization. When consciouly perceived, the correction to vocalization was modulated ~500 ms after the pitch shift.

New study I was happy to be part of: Gestational Duration and Postnatal Age-Related Changes in Aperiodic and Periodic Parameters in Neonatal and Toddler Electroencephalogram (EEG) onlinelibrary.wiley.com/doi/10.1002/... #EEG #neuroimaging

We observed that fast withdrawal movements were associated with strong P1 responses, suggesting an early attentional amplification. However, strikingly, EPN showed the opposite pattern: fast behavioral withdrawal correlated with weaker EPN.

Using EEG we first replicated the finding that threat stimuli are associated with an amplified early-visual responses (P1 wave), and that they later produce "Early Posterior Negativity" (EPN). These effects are often interpreted as correlates of attentional priorization of threat-relevant stimuli.

To test if the faster withdrawal is specific to "naturalistic movements", we repeated the experiment but asked participants to respond using a button press ("approach") or release ("withdraw"). Result: no differences in reaction times to different animal stimuli.

We observed that participants withdrew their hand from snake or spider stimuli faster (decreased RT, and increased hand acceleration) than from non-threatening animals (birds and butterflies). Crucially, similar effect was not seen when participants approached the stimuli.
