The Social Computation and Representation Lab talk series is back tomorrow! And no better way to start the new academic year than by following @setayeshradkani.bsky.social 's talk as she weaves together two complementary strands of her investigations into social cognition.

How do exclusion and adversity drive social learning in adolescence? Here, @drjk.bsky.social, Lyn Ellett and I show that social exclusion reduces adolescent belief flexibility about others at a later point in time, and reduces the ability to generalise from social cues - 🧵 1/5

What connects difficulties in social cognition, self-awareness, and abstract reasoning in those with Corpus Callosum Dysgenesis (CCD)? Here, across three experiments, we find that the corpus callosum is integral to metacognitive efficiency - www.biorxiv.org/content/10.6...
Gemini said
This schematic outlines three experiments (Online, Lab, and VR) comparing individuals with Cerebral Cavernous Malformations (CCD) to Neurotypical (NT) controls using Random Dot Kinematograms (RDK).

Panel A: Study Overview
Experiment 1 (Online): 10 CCD vs. 85 NT participants using a computer mouse.

Experiment 2 (Lab): 11 CCD vs. 7 NT participants using a button box.

Experiment 3 (VR): 10 CCD vs. 13 NT participants using a VR headset.

Brain Icon: A blue line divides the hemispheres with a crossed-out arrow, suggesting a focus on disrupted interhemispheric communication.

Panel B: Classic RDK (Exp 1 & 2)
A trial sequence on a grey background:

Fixation (1600ms): A central cross.

Motion (1500ms): A circular field of moving dots (red, blue, and white).

Decision (Unlimited): Selection of "L" or "R" buttons.

Confidence (Unlimited): A slider ranging from "Decrease" to "Increase" to rate certainty.

Panel C: VR RDK (Exp 3)
A faster trial sequence used in the VR environment:

Fixation: Until central fixation is achieved.

Motion (180ms): Dots appear within a narrow vertical rectangle.

Decision (Unlimited): A prompt shows blue/orange bars for direction selection.

Panel D: Visual Presentation (Exp 3)
Diagrams showing how stimuli are mapped from the eyes to the brain hemispheres (L and R):

Binocular: Stimuli presented to both eyes, traveling to both hemispheres.

Lateralised: A 3° shift from center presented to one eye.

Monocular: Stimuli presented to one eye, directed specifically toward the right or left hemifield to isolate hemispheric processing.
