short term memory studies

Question 1

weakness: general PEEL lacks mundane realism

Answer 1

research into (duration of stm) lacks mundane realism as artificial task of (recalling consonant trigram) is artificial, difficult to generalise findings (information lasts 18-30 seconds) to real life examples of (duration) as research does not reflect most real life memory activities as what we are trying to remember is meaningful, lowers external validity

Question 2

strength: general PEEL high control over extraneous variables

Answer 2

research into (coding of stm) has high control as was carried out in a controlled lab setting, for examples (list of words would have been matched on level of difficulty and shown to ppts for same amount of time), this makes it possible to establish and effect between IV and DV, increasing internal validity of research

Question 3

strength: general PEEL high reliability

Answer 3

research into (capacity of STM) is high in reliability as was carried out in a controlled lab setting so research can be repeated in same conditions (same standardised instructions and same digits given) to check for consistent results
