To study the effect of type of stimulus on memory recall, Hayden has participants receive either an auditory or visual presentat
ion of a poem. After the presentation, participants are asked to answer several questions about the poem. Hayden has employed which type of experimental design?
Explanation: from my point of view the post test only is the answer because Hayden prefers to test the participants only after they have been in touch with the poem, that means that they hear or read it already.
Scout, Jem, Atticus, Dill, Arthur Radley, Bob Ewell, Maudie Atkinson, Calpurnia, Stephanie Crawford (Maybe Uncle Jack, they might mark your answer for not including him)
