its face-likeness and symmetry? And can we assess it across human and non-human apes (orangutans, chimpanzees and bonobos)? 2/

Murillo then moves to an ongoing study directly assessing the hypothesis that the function/practice in which semiotic artifacts are used shapes them over time (registered report: https://www.sciencedirect.com/science/article/pii/S1090513824000357). 3/

Transmission chains are set up in which participants produce decorations, differentially mark their group identity (against another group), or communicate about referents. 4/

The last eSymb project presented by Murillo investigates what could be the cognitive reasons behind the prevalence of side-views in cave art, as well as the presence of abbreviated depictions. Does side-view afford easier recognition (eco-psych says it's the only good view)? 5/

Side views are easy to recognize and are easy to draw.

fusaroli.bsky.social•52 days ago

apparently for the participants they are just as easy as oblique views (but easier than frontal and posterior views)

fusaroli.bsky.social•53 days ago

Does abbreviation facilitate recognition (eco-psych says not)? The data point to oblique and side views being equally recognizable, but oblique views are harder to draw and likely require teaching. Abbreviations are also harder to recognize and less preferred, but easier to draw.

Now @izzywisher.bsky.social on figuring out the practices surrounding cave art, its making, development and fruition; and how cognitive science can inform this investigations /n
