Moray✅ Flashcards
What type of task is it when messages were played to BOTH ears at same time?
Binaural task
What type of task is it when messages were played to EACH ear?
Dichotic task
What study was moray testing?
Cherry’s dichotic listening study in 1953
Aim:
- test cherry’s study
- test effects of hearing your own name
- test affects of instructions to identify a specific target
What type of experiment?
Lab, 3 separate studies
How pps in each study?
1- not recorded
2- 12
3- 14
Mixed sex, undergraduates or research workers
What were some controls of the study?
- used same male voice for recordings, and rejected messages were played at same volume to shadowed message
- pps used headphones
Study 1-
Repeated measures
List of simple words repeated 35 times (unattended message)
3 IVs: rejected message, shadowed message and control
DV measured in 3 ways: recognition test that included words from shadowed, rejected and a new set of words
Results of study 1-
-No evidence of words from rejected message being recognised
Study 2-
- repeated measures
- 10 short passages
- 6 conditions with instructions, 4 without
- 3 of the 6 included pps name
- IV- was name used or not (affective/ non-affective)
- DV- how frequently instructions were heard
Results of study 2-
Results show that using pps name allowed them to hear the instructions more frequently (20/39) than without name (4/36)
Study 3-
- independent measures
- digits (experimental) / no digits (control)
- pps always shadowed an experimental message (1 group told they would be asked about this other told they should remember all the numbers they could- IV)
- DV- mean number of digits reported
Results of study 3-
Results show no particular difference for this condition- stimulus did not appear to be ‘important’ enough to brake through attentional barrier- unlike pps own name
Conclusions:
1- when attention is directed to one ear, all the content of rejected messages is blocked
2- important messages like one’s name can brake block
