It is widely agreed on the memory-enhancing function of sleep. The authors (Drosopoulos, Schulze, Fischer and Born, 2007) performed two experiments to seek the influence of ex post facto interference on the sleeps contribution for consolidation of memories. The experiments were based on two preceding(prenominal) studies (Ekstrand, 1967; Ekstrand, Sullivan, Parker and West, 1971) (as cited by Drosopoulos et al., 2007).
Ekstrand (1967) built his experiment on testing the information of 2 paradigm word-pair lists (A-B and A-C) followed by sleep and wakefulness, and he put up out sleep contributed more to the first (A-B) than to the second (A-C) list. Thus, Ekstrand (1967) conclude that sleep after learning improved memory from retroactive interference (Drosopoulos et al., 2007). However, Ekstrand et al. (1971) performed a second study by use the same A-B and A-C lists and tested recall immediately, 20 min, and 7 hr after learning (Drosopoulos et al., 2007).
The result showed retroactive recovery already happened 20 min after learning, thus he went to a conclusion that memory improvement for the first list was out-of-pocket to the prior sleep memory recovery (Drosopoulos et al., 2007).
Experiment 1: Reexaming the Ekstrand Findings
Drosopoulos et al. (2007) ameliorated Ekstrand (1967)s experiment by adjusting some procedures and introducing some adjunct control conditions to determine sleep did affect memory consolidation from retroactive interference.
Method
participants. Drosopoulos et al. (2007) randomly selected 90 healthy, non-smoking, drug free, native communicative individuals (45 men and 45 women, mean fester 24 years, age range 1934 years) with no prior write up of sleep disturbances and a regular sleepwake cycle. Participants were postulate to relieve oneself up at 7:00...If you want to get a full essay, order it on our website: Orderessay
