What research method did Bahrick use?
Bahrick et al. (1975) studied enduring memories using a quasi-experiment design which involved 392 participants ranging in age from 17 to 74 years. Participants were divided into nine groups according to the elapsed time since graduation.
What did Bahrick et al find?
Bahrick found that 90% of the participants were able to correctly match the names and faces, 14 years after graduating and 60% of the participants were able to correctly match the names and faces 47 years after graduation.
What type of experiment was Bahrick et al?
Very Long-Term Memory Experiment. Bahrick, Bahrick, and Wittinger (1975) investigated what they called very long term memory (VLTM). Nearly 400 participants aged 17 – 74 were tested. Participants were asked to list the names they could remember of those in their graduating class in a free recall test.
How does the research of Bahrick support the MSM?
Conclusion: Bahrick concluded that people could remember certain types of information, such as names and faces, for almost a lifetime. These results support the MSM and the idea that our LTM has a lifetime duration (at least 47 years), and is semantically encoded.
What did Jacobs do 1887?
Research into capacity: Jacobs (1887) developed the digit-span technique, where a participant has to immediately recall a sequence of letters or numbers which increased by one letter or number with each trial.
How long do short-term memories last?
approximately 20 to 30 seconds
Most of the information kept in short-term memory will be stored for approximately 20 to 30 seconds, but it can be just seconds if rehearsal or active maintenance of the information is prevented.
What is maintenance in psychology?
Maintenance Rehearsal is the process of repeatedly verbalizing or thinking about a piece of information. Your short term memory is able to hold information about about 20 seconds.
What does coding mean in psychology?
Coding refers to the interpretations a person gives to experiences. In personal memories, a single association with some present event can trigger detailed memories of past experiences. Psychology has developed several ideas about the nature of organization in memory.
Who is Clive Wearing psychology?
Clive Wearing (born 1938) is a British citizen suffering from an acute and long lasting case of anterograde amnesia, the inability to form new memories. On March 29, 1985, Wearing, then an acknowledged expert in early music and at the height of his career with BBC Radio 3, fell ill with a herpes simplex virus.
What did Jacobs investigate?
Evaluation: Miller’s (1956) theory is supported by psychological research. For example, Jacobs (1887) conducted an experiment using a digit span test, to examine the capacity of short-term memory for numbers and letters.
What is a strength of the Jacobs 1887 study?
EVALUATION OF JACOBS (1887) Strength. Study is lab experiment therefore establishes cause and effect. Had high control over extraneous variables be confident that IV (the number of digits or letter) affected the DV (amount participants could recall) Strength because results are reliable.
