PSYU2239 - Attention Flashcards
(28 cards)
How do we follow one conversation at a noisy party, aka cocktail party problem (Problem, not effect)?
Selective attention
Cocktail Party Effect - Describe dichotic listening task
Subjects asked to shadow (repeat back) message on one ear and ignore the other
Describe Cherry’s (1953) findings about dichotic listening task
Physical characteristics of the unattended ear is identified, but semantic content is not processed
- Male/Female
- Loud/Soft voice
- High/Low voice
Describe Moray’s (1959) findings about dichotic listening task
Meaning also not processed in the unattended ear, but name is detected
What is the phenomenon called from findings derived from Moray’s findings?
Cocktail party phenomenon/Identification paradox
What does the bottleneck models all assume?
- Multistore model of memory architecture
- Information transferred from sensory store to STM
Broadbent’s Filter Model
1. Bottleneck as a _____ filter
2. If input is blocked by filter, ______ is processed; if input isn’t blocked by filter, ___ is processed
3. Selective filter to prevent overloading of ______
- All-or-none
- Physical characteristics; semantic content
- Limited capacity STM store
Treisman’s attenuation model
1. What is the keyword in this model?
2. What does the model oppose against Broadbent’s filter model?
3. What kind of stimuli have lower threshold?
- Attenuator - turns down processing of unattended information
- Bottleneck is not all-or-none; it’s the degree of processing
- Context-appropriate stimuli (Meaningful context - like name)
Why does own name have low threshold, according to Treisman’s attenuator model?
It has high salience (personal meaning)
Deutsch x2 Model
1. Assumes that information is analysed _____ (physical, semantic), even in unattended message
2. Bottleneck is ___ : ____ for action
- Fully
- Late; Selection
[Battle between early vs late selection - Treisman vs Deutsch]
Describe the procedure of Treisman & Riley’s (1969) experiment
- Ss presented two messages to two ears
- Shadow one message, while responding to target word in either ear by tapping
What did Deutsch x2 argue about the findings about Treisman and Riley’s experiment?
Unattended message has lower target detection because Ss has to do two tasks - shadowing and tapping
Ss are required to prioritise shadowing, hence detection on unattended ear is lower although meaning is fully processed in both ears
Assumption of flexible bottleneck view
Unattended message not always processed fully to the level of meaning
Procedure of Johnston & Wilson’s (1980) experiment
- Ss presented with a list of words dichotically
- Instructed to detect a target - member of a semantic category
- Non-target presented simultaneously with target (can be either ear)
- Critical targets - ambiguous meaning (Organ)
- Interpretation biased by non-target (Church - Organ; River - Organ; Liver - Organ)
IV & DV of flexible bottleneck view
IV: Types of non-target; conditions
Appropriate, Neutral, Inappropriate
Focused attention; Divided attention
DV: % of target detected
Discuss the findings of Johnston & Wilson’s experiment
In focused attention condition, no effect of type of non-target on target detection
In divided attention condition, appropriate > neutral > inappropriate
What are the differences between early and late selection results based on Flexible bottleneck view results?
Bottleneck is flexible.
Early selection during focused attention trial - words are still processed to a certain degree but has no effect on DV
Late selection: Meaning of non-target was fully processed in divided attention trial
What does flexible bottleneck view suggests?
More stages of processing (____ -> ____), the _____ the demands on _____ capacity
Selection occurs as ____ in processing stages as possible to _____ __(same answer as above)_ demands
Physical; Semantic
Greater
Attentional
Early
Minimise; attentional
What determines dual task performance
Task Similarity
Practice
Two similarity factors affecting dual task performance; give examples
Stimulus modality - type of sensory input
- Looking at your phone (visual) while driving (Visual) > listening to music (auditory) while driving (visual)
Response modality - type of response or action needed to take
- Sending text interferes with driving more than talking on the phone
Characteristics of automaticity
- Fast
- Little attentional capacity
- Inflexible
- Unavoidable
- Unavailable to consciousness
