study 1
given either sucrose or food, some apired with LiCl to see if reduces lever pressing (makes sick)
P groups should show less responding
sucrose/LiCl groups do press lever - food pellet/LiCl do press sometimes - sucrose was always left cus sticky
supports Tolman's cog account - have encoding of consequence of actions, but animals in LiCl still making response so law of effect must still be working too
study 2
group 1 = 500 training trials - group 2 = 100 trials
group 1 had no differences in response to outcome - always press lever
group 2 differed - if outcome was devalued then reduced number of presses (when paired with LiCl)
when have more trials, they dont learn devalued outcome - both SR and cog account going on - instrumental is mediated by both systems
