(52 cards)
What is cognitive psychology?
Area of psychology that studies mental processes such as thinking, memory, planning, reasoning, attention and perception.
what is Inattentional blindness?
Failure to see something we’re looking at, occurs because attention is preoccupied.
Example of Inattentional blindness
Basketball video (Simons & Chabris, 1999)
Is Inattentional blindness in the eyes or brain?
In the brain.
Eye tracking can show where people are directing their eyes - People who didn’t see unexpected item looked at it as often as those who did!!!
What is change blindness?
We’re very bad at noticing even large changes, failure to update representations between views.
Example of change blindness
Plane - engine disappearing
What is a feature search?
- Any certain features always noticed
- Visual pop out: The idea that some basic features don’t need attention to be seen
What is a conjunction search?
- May be primitive features
- When you are combining features together, to find those items you need to use your selective attention
- Have to look around in a serial manner to find the bit that changed.
What is the Feature Integration Theory?
Certain basic features are processed automatically (don’t have to think about it) and in parallel (process the entire visual field at once, not one object at a time)
Example of the Feature Integration Theory
You instantly notice a red dot among blue dots — your brain detects the color difference without effort.
What is top-down attention
Voluntary, purposeful, strategic directing of attention.
Example of top-down attention
Finding a friend in a crowd when you know that they are wearing red.
What is bottom-up attention
Reflexive, some things seem to grab attention on their own
Example of bottom-up attention
A fire alarm - not because we were looking for it but because it jumped out at us
What is the cocktail party effect?
We can pay attention to one conversation in a noisy room, and seemingly “tune out” the others…except we’ll usually hear if someone says our name!
What is the dot-probe task and what does it study?
- Dots shown on left & right of screen, participants need to say which side, responses as fast as possible (speeded)
- Before dot appears there are 2 images (one emotional, one neutral)
- Most drawn to emotional image
- Measures attentional bias
What is attentional bias?
Bias toward emotionally threatening over neutral images in people with anxiety
(People with anxiety: faster to notice negative emotions (like anger or fear), slower to stop looking at them or shift attention away)
What is the emotion-induced blindness task?
Who developed it?
A series of images - task is to look for the rotated image
Steve Most (NSW)
our attention ‘prioritises’ things that are ________.
emotional
What is memory?
The processes that allow us to
record, store, and later retrieve
experiences and information.
What is encoding/recording?
The process of taking in information and converting it into a form the brain can store and later retrieve.
It’s the first step in creating a memory.
What is storage?
The process of keeping encoded information in the brain over time, so it can be used later.
What is retrieval?
The process of accessing and bringing stored information back into conscious awareness when you need it.
Three stage model of memory (TSMOM) - Explain sensory memory
The first stage — where information from the environment enters through the senses (sight, sound, etc.)
A brief, high capacity, representation of what is being sensed:
- Iconic: visual sensory memory (lasts about 1⁄4 of a second)
- Echoic: auditory sensory memory (lasts about 2-4 seconds)
