Table 1.

A comparison of the support (based on Akaike weight) for different social learning models and the asocial learning model. Italicized variables indicate the models with most support.

model form	rate of social transmission same/different across tasks	smooth-coated otters	Asian short-clawed otters
asocial		12.3%	59.4%
social transmission
additive model	same	7.0%	20.1%
	different	0.8%	1.5%
multiplicative model	same	79.4%	19.6%
	different	0.6%	0.5%
