Changes from voice to a tone Changes from male to female
26
What assumptions are shared by Broadbent's 1958 and Treisman's 1960 model ?
Selection occurs on the basis of physical characteristics The perceptual systems have limited capacity Perceptual information is a subject to a selective filter
27
What is true of early selection theories ?
Unattended information is not identified
28
According to Broadbent, on what basis is irrelevant information filtered out ?
Physical stimulus properties
29
What is the point of a flanker test ?
Tests the ps ability to ignore distracting information
30
According to Lachter 2004, what is slippage ?
A temporary shift in attention to an unattended channel
31
According to Lavie 1995, is processing limited ?
Yes, if attended information consumes all processing capacity then nothing else will be attended to
32
What is repetition priming ?
When the prime word is the same as the test word
33
What did Lacie and Cox 1997 class as a high perceptual load ?
A stimulus that required search for the target
34
Is there a difference in compatibility effects ?
Yes, there is an effect in low perceptual load trails but not in high perceptual load trial
35
When perceptual load is low, perceptual load is low, processing of an irrelevant channel is...?
Unavoidable
36
What do change blindness and inattentional blindness have in common ?
They are both a failure to perceive things that are easily seen once noticed They are both believed to be due to a lack of attention
37
Simons 2000 found that changed in an image can be hard to detect if...?
The change occurs slowly

What is a difference between change blindness and inattentional blindness ?
Whether or not memory has a role
39
What does the interactive activation model assume ?
There are levels of representation associated with features, letters and words There is bi-directional activation between levels Activated units at one level exert lateral inhibition on other units
40
According to the logogen model what words require less activation before firing ?
Logogens associated with high frequency words
41
When you hear the word mechanic readers assume its a male. What is this called ?
An elaborative inference
42
According to the minimalist hypothesis (Mackoon and Ratcliff 1992), when can automatic inferences be made ?
