Q
Attention
A
- Helps navigate you through your surrounding brimming with information and distractions.
- According to William James: It implies the withdrawl from some things in order to deal effectively with others.
3
Q
Selection
A
- The act of focusing in on one subset of available infromation deemed most important.
- This allows us to shift through a wealth of information available to us.
EX. When your first put on clothes, feel the fabric against your skin, but throughout the day, the you become unaware of this feeling. UNLESS, something triggers you to pay attention to the feeling of your clothes again.
4
Q
Automatic Process of Attention (SALIENT)
A
- Trigered involuntarilty by external events.
- Involuntary “capture” of attention
- Operate in a fast, efficient and obligatory manner.
- Consciously effortful tasks can become automatic through practice.
- SALIENT information captures our attention automatically
EX. attention is directed towards the sirens of an ambulance
5
Q
Controlled
A
- Processes guide attention voluntarily and consciously to objects of interest.
- This process occurs more slowly because they are assumed to require more cognative effort.
EX. While driving, you are making consciously choosing to pay attention to many aspects of the environment to guide this goal directed behaviour (i.e changing lanes, speeding up, slowing down)
NOTE: as demands require more attention, we must adjusst to compensate (turning down volume in car)
6
Q
Spotlight model
A
- Conscious visual attention focuses like a spotlight.
- ## Our attention shifts to different stimuli, and items falling within the spotlight are more easily perceived and processed.
7
Q
Filter model
A
- Bottleneck which selects only a limited amount of information based on physical characterisitcs to pass on for further processing.
- We use auditory cues to filter target sounds from background noise
- Single filter model
- Dual filter model: Ranks the physical cues of audiory sounds (intensity, pitch, relevence) and passes it along the semantic/ late filter to undergo further processing.
8
Q
Bottom-up Processing
A
- Raw data gathered by our senses/ piece together smaller peices of sensory.
- Also said to happen when attention is “captured” by salient (most notable) changes in the enviroment.
- Automically capture your attention in a reflexive manner to alert you.
- We allow the stimulus itself to shape our perception, without any preconceived idea.
9
Q
Top-down processing
A
- Using a combination of our memories, biases, and heuristics to interpret infortmation.
- Based on prior experience to fill in the blanks.
- Stratigically direct your attention to match you current goals and expectations.
EX. Putting keys on the front desk when returning home which makes for a direct search to the front desk.
10
Q
Oritenting
Tools to measure attention
A
- The act where attention moves across the scene.
- Posner’s spatial cueing paradigm: allows to measure shifts in attention in the absesne of eye movement
11
Q
Overt vs convert orienting
A
- The obvious process of looking to where you are attending your attention is overt orienting.
- Attending to something without looking is convert orienting.
EX. our gaze may be politely focused on Wilma who is in conversation with you, but your attention covertly shifts toward the door in anticipation of Waldo’s arrival. This will make you notice Waldo faster when he finally does arrive.
12
Q
Visual Search Paradigms
A
- Used to study how we search for items in our enviornment, where particpants are asked to locate a target item among a set of distractors.
13
Q
Set size
Visual Search Paradigms
A
- The total number of items during a visual search task. Can vary from trial to trial.
14
Q
Pop-out effect
Visual Search Paradigms
A
- The bottom up capture of attention driven by a salient physical property of the target during a visual search task. If a target “pop-out”, seach time is unaffected by set size because the processing of the whole set of items happends simultaneously or in parallel.
- ## Physical properties can be something like colour
15
Q
Conjunctive Search
Visual Search Paradigms
A
- Sometimes the target is not the most salient in the scene. We cannot rely on unique features to distinguish the target from the distractor, and instead must search for the combination of multiple different features.
- When an item does not pop-out during a visual search task, you must examine each item individually to determine if it is the target.
- As set size increase, so does time.
EX. looking for a red circle in a set size that includes red square, blue circles, and blue squares.
