Study 1 Glanzer and Cunitz (1966) practice test questions and answers(100% verified for accuracy )

Aim Aim: Glanzer and Cunitz tested the hypothesis that short term memory and long term memory are two separate stores in a free recall experiment. Serial Position Effect: the observation that when given a list of items to remember, we tend to remember the first and last better than the middle items. Description of Methodology Description of Methodology: - Two groups of Participants composed of 240 Army enlistees - Same list of 20 words (common, one-syllable words) Group 1: control; recalled the words immediately after presentation in a free recall (any order they wish) Group 2: experimental; had to memorize words while counting backwards in threes, making rehearsal very difficult. Afterwards, they had to recall 30 seconds after rehearsal in a free recall. Results Results: - Group 2 could only remember a few words and while the first words had been rehearsed, delaying the recall by 30 seconds prevented the "recency" effect. Conclusion Conclusion: Group 1 was able to remember the words a lot better than Group 2, supporting the fact that there are different memory stores; long term and short term. Evaluation Evaluation: - The participants were all male and may possibly differ in brain capacity - Study is not widely generalizable due to the fact that they are all male participants - Lacks ecological validity due to the fact that it isn't present in everyday situations to memorize a list of words unless you are memorizing a phone number or something.
