Answer 3

Broadbent’s filter model of attention. model of attention that proposes a filter that lets attended stimuli through and blocks some or all of unattended stimuli; based on Cherry dichotic listening task and cocktail effect; also called bottleneck model because filter restricts information flow.

Question 4

In the dichotic listening task, Moray (1959) found that subjects noticed their own name being mentioned in the to-be-ignored message. Which is the following is true about this finding?

Question 2Select one:

a.
It shows semantic processing of unattended information
b.
It is consistent with Broadbent’s filter model
c.
It is inconsistent with Broadbent’s filter model
d.
Both a and b
e.
Both a and c

Answer 4

e
This question tests your understanding of the implication of an experimental finding. The fact that information in the unattended channel was processed semantically is inconsistent with the assumption of Broadbent’s filter model.

The correct answer is: Both a and c
