What is the area
Cognitive
What was the aim of the study
To investigate factors influencing the amount of information recognized in an unattended message
Research method
3 lab experiments
Sample
Male and female undergraduates and research workers
12-14 ppts
Controls
- loudness was matched for each ppts
- participants were given practice at shadowing first
- all passages were recorded by one male speaker at a rate of 130 wpm
Experiment 1
Repeated measures design
What was the aim for experiment 1
To see how many words from a list in the unattended message were recognised
What were the results for experiment 1
There was no evidence of words from the rejected message being recognised
Therefore information in the unattended ear does not break through the attentional barrier
Experiment 2
Repeated measures
What was the aim for experiment 2
To see the effect of hearing your own name in the unattended ear does not break through the attentional barrier
What was the IV for experiment 2
Whether instructions were prefixed by the participants own name or not
What was the DV
The number of affective instructions perceived
What were the results
The presence of a name causes the instruction to be heard
The affective content in an unattended message can break through the attentional barrier
What was the aim for experiment 3
To show that instructions might alter the chances of material in the rejected message being perceived
What design was experiment 3
Independent measures design
What was the IV for experiment 3
Whether the ppts were told beforehand that they had to answer questions about the shadowed message at the end of each passage or told to remember all the numbers s/he could
What was the DV for experiment 3
The number of digits correctly reported
What were the results for experiment 3
There was no significant difference between the mean number of digits reported under two conditions
Therefore even when alerted to the possibility of hearing digits, ppts’ perception was not affected
