Attention Flashcards
1
Q
Attention
A
- Focus a mental resource on a specific internal or external stimuli
- Active and limited process
2
Q
Selective attention
A
-Ability to attend to one source of information and exclude others
3
Q
Applications
A
-Consumer, education, multitasking and safe driving
4
Q
Hard to study
A
-Hard to define, operationalise and measure
5
Q
Importance
A
-Identify how information is processed and the limitations.
6
Q
Covert attention
A
- Not externally observable e.g. listening to a conversation while looking at something else.
- Can sometimes be tested by EEG but is impacted by eye movements
7
Q
Overt attention
A
-Externally observable e.g. gaze direction.
8
Q
Functions
A
- Focusing (reduce items processed)
- Binding (combining info)
- Perceptual enhancement (increase gain)
- Action Selection
- Sustaining Behaviour despite distractors
9
Q
Tod-down processing
A
- Attention is driven by past experience, expectations and knowledge
- central cues: based on meaning can be ignored
- when reading letters are processed by meaning
- Charlie Chaplin once lost a Charlie Chaplin lookalike competition due to judges preconceived ideas
10
Q
bottom up processing
A
- Attention is based on the stimuli that captures attention
- Colour and orientation pop
- Peripheral cues: based on stimuli cant be ignored
11
Q
Spotlight analogy
A
- Illuminates a specific region of space, stimuli in this region processes stimuli more efficiently
- independent of vision, covert, fast and active
- Supported by attentional cuing which found true cues resulted in faster responses as attention moved to the correct response
- Weakness: spatial attention rather than object based
12
Q
Limited processing capacity
A
- Information is processed serially and cannot be processed simultaneously
- Support: During WW2 pilots found monitoring so much information difficult
- Shorter delay between stimuli results in slower responses
13
Q
Information bottleneck
A
- Before bottleneck info is processed serially without attention
- After bottleneck information is processed with attention to determine the meaning and response
- Location unknown
14
Q
Filter theory
A
- Before filter only low level auditory characteristics are processed e.g. pitch, intensity and location.
- After the filter meaning and response is determined
- Support: dichotic listening task found participants could only report low-level information about info in the unattended ear
- Weakness: cocktail party effect
15
Q
Attenuator theory
A
- Unwanted ingomtion is simply turned down before the filter, meaning is still processed and priority is determined
- After the filter response is determined
- Support: Cocktail party
- Switching stories during dichotic listening task found participants could switch stories to answer questions
- Weakness: attention is covert
