- Moray (1959) - Dichotic listening
- Research Method
- Strengths
- highly controlled laboratory experiment - high internal validity
- weakneses
- people may show demand characteristic
- listening to sounds through headphones doesn't represent real life - low ecological validity
- Laboratory Experiment
- repeated measures design
- Strengths
- Reliability
- standardised method
- Validity
- strengths
- highly controlled laboratory experiment - high internal validity
- lack of extraneous variables - increases internal validity
- weaknesses
- listening to sounds through headphones is artificial - low ecological validity
- strengths
- Sample
- strengths
- easily accessible
- saved time and money
- weaknesses
- not representative as only used students and research workers - low population validity
- 12 pps in exp 2
- 2 x 14 pps in exp 3
- strengths
- Data Type
- quantitative data on the amount they remember
- qualitative data on how they react to the listening task
- Ethics
- Deception as participants may have not been fully informed on the aims of the study from the beginning
- Ethnocentrism
- It is ethnocentric as it is possible that people from other cultures may not focus their attention in the same way
- It isn't ethnocentric as attention is biologically driven and universal so we would expect similar results
- Procedure
- experiment one
- a short list of words were repeated in one ear (35 times) whilst they shadowed a message from the other ear
- experiment two
- in some passages there were instructions and sometimes these instructions were prefixed with their name
- experiment three
- passages had numbers mixed into the text
- took part in a recognition test where they had to identify the words or number that they remember
- experiment one
- results
- experiment 1
- words presented in shadowed message = 4.9/7
- words presented in rejected message = 1.9/7
- words presented for the first time in recognition test = 2.6/7
- experiment 2
- most participants ignored the instructions as they thought it was an attempt to distract them
- 39 (number of times presented + affective)
- 20 (number of times heard + affective)
- 36 (number of times presented + non-affective)
- 4 (number of times heard + non-affective)
- experiment 3
- results were insignificant
- experiment 1
- conclusions
- when a pps only listens in one ear, almost none of the other content will penetrate the mind block
- important messages can penetrate the block
- Research Method
