The Experiment Research Study: Craik and Tulving (1975)

gallery To investigate depth processing by giving participants s payoff of tasks requiring different levels of processing and measuring recognition.Participants Controlled fit (3 males and 3 females) Experimental condition (3 males and 3 females) Independent group constructMethod This was a repeated measures design try out with three conditions. Participants were minded(p) a list of 60 words, one at a time and were required to process each word at one of thee levels (the independent variable). At deep level they might be asked a question, such as Does this word fit into the sentence? At an intermediate level, they might be asked Does this word rhyme with? At school level, they might be asked, Is this word in capital letters?Following the task, participants were (unexpectedly) given a list of 180 words, which contained the original 60 words elegant and 120 filler words, and were asked to identify the ones they recognised from the original 60 (the dependent variable).Measuremen t The both conditions create room for accurate comparison and results. Participants are referred to with numbers.Results Significantly more(prenominal) words were recognised if they had been processed at deep level (approximately 65 per cent) than either phonetic (37 per cent) or shallow (17 per cent) levels.Conclusion As deeper processing resulted in better recognition, then the level at which material is processed must be related to memory.Evaluation This study relies on incidental learning (the participants didnot know they would be asked to recall the words), rather than intentional learning, which is the advantage of be more true to real life. This means participants are unlikely to quest after in extra processing which could invalidate the results. However, there is a necessity level of deception required in suck a design which raised ethical issues.
