However it does not directly test the role of eliciting surprise for these memories to be formed, it was just assumed that the events were sufficiently surprising, as well as not directly testing the role of covert rehearsal.]]> 2020-05-11 01:11:58 UTC https://padlet.com/popov_research/fhx36kije20jcej/wish/563656956 Sperling (1960) https://padlet.com/popov_research/fhx36kije20jcej/wish/563662389
  • opportunity sampling, sample may not be representative of target population
  • psychology students - may not be generalisable to other people, might 
  • high internal validity - highly controlled lab experiment, can ensure IV influences DV, can be easily replicated 
  • allowed researchers to demonstrate the theory as it was a detailed experiment 
  • low ecological validity - not generalisable to real life settings, very artificial conditions, not representative of memory in everyday circumstance

  • no experimenter bias: given questionnaire therefore no emphasis can be placed on verb, unlike emphasis potentially given in a spoken interview
  • potentially testing effect, however control group was used and a difference was found therefore effects of this bias are less prominent

    Quasi-Experiment: Allocation into groups are based on pre-existing differences - age
    Study is highly demanding in cognitive ability - 5 and 7 year olds might not understand the tasks given by the experimenters 
    Construct Validity: 
    1. Multiple prizes of the same item could still be viewed as rewarding by a subject 
    2. Similarly, different prizes could be viewed as less rewarding towards some subjects
    (Prizes could be of different value towards subjects) 
    Rational behaviour was defined as “opening more windows when cost was low and benefits were high” within the experiment, this definition of “Rational behaviour” is not necessarily applicable to all real life situations 

    Strengths: 
    Sample of children used is of 5 and 7 years of age: generalisability and population validity is high as their study is based around children
