Study 1: Participants who saw pictures (M = 17.00, SD = 8.37) did not recall more items than those who saw words (M = 9.00, SD = 6.52), F(1, 8) =  2.86, p = .13. Study 2: Participants who saw pictures (M = 18.00, SD = 6.87) recalled more items than those who saw words (M = 10.00, SD = 5.35), F(1, 12) = 5.90, p = .03. Why did the researchers obtain different results?
