Interesting new work from @fernandosanchezh.bsky.social suggesting a developmental distinction between costly and non-costly rejections of disadvantageous offers in an inequity game.
Are 2-year-olds inequity averse?
In our new Journal of Experimental Child Psychology paper, @dchyde.bsky.social and I find that 2-year-olds show sensitivity to disadvantageous offers only through non-costly responses, while 4-year-olds respond in both costly and non-costly ways.🧵
