when ''internal'' retrieval cues are different when recalling compared to when the coding took place
eg trying to recall information learned when sober and then trying to recall it when drunk
what did Overton do?
got pps to learn material when drunk or sober and found that recall was worse when pps were in a different internal state at recall compared to coding learning/ for example if learnt when drunk was recalled better when drunk than sober
what did DARLEY ET AL find?
found that pps who hid money whilst on marijuana were less able to recall where the money was when they were not high (compared to when they were high again)
