Attention (Chapter 4) Flashcards
Define attention.
-the ability to focus on specific things
What two processes does attention include?
-conscious and unconscious
What is the conscious aspect of attention?
-links past to present, helps us adapt, planning and control of future actions
What are the preconscious aspects of our attention?
-they lie outside our conscious awareness, some may be made conscious, some not
What is priming?
-exposure to one stimulus influences the response to a subsequent stimulus
What is positive priming? Example? (2)
-exposure to a stimulus speeds up the processing of later stimuli
Example: If you see the word doctor and later respond faster to the word nurse than to an unrelated word
What is negative priming? Example? (2)
- exposure to a stimulus slows down the response to a subsequent stimulus
Example: if you’re asked to ignore an object, a red pen) and then later respond to it, pick out the red pen, you might do so more slowly.
What is selective attention?
-ability to focus on one message and ignore all others
Describe the experiment by Cherry known as the cocktail party effect experiment.
-used a method called dichotic listening, in which participants were presented with two different auditory messages, One of the tasks given to participants was to shadow (or repeat out loud) the message they heard in one ear while ignoring the other.
What was the result of Cherry’s experiment?
-it showcased selective attention, Participants were able to focus on one message (shadowed message) and successfully repeat it, but they had very limited awareness of the content of the other message (non-shadowed message) playing in the other ear.
What is subliminal perception?
-process by which individuals are exposed to stimuli below their conscious awareness, meaning they cannot consciously perceive or recognize these stimuli, yet these subtle signals can still influence thoughts, feelings, or behaviors.
Tell me about Vicary’s experiment?
-he said he was using subliminal messaging in his movie theatre to get more popcorn sales but he ended up saying he was lying
What is blindsight?
-individuals with damage to the primary visual cortex (V1) can respond to visual stimuli without consciously perceiving them.
What is divided attention?
-attending to two or more things at once
What are supertaskers?
-can perform multiple tasks simultaneously without any decline in cognitive performance
What was the experiment by Schneider and Shiffrin?
-they got people to memorize a signal number and then flashed a bunch of letters at them and they had to see if the number was in that group
What are consistent mapping conditions?
-targets in attention experiments and distractors are always from different categories, one is number the other is letter
What is an automatic task?
-occurs without intention, often with practice
Why is an automatic task helpful?
-requires less cognitive power to do, you don’t have to think about it
What is a varied mapping condition?
-rules keep changing from trial to trial, like one trial you look for a p and the next you look for a T which is hard because they look similar
What did Schneider and Shiffrin find in their second experiment?
-they had to show the frames for a longer period of time for people to achieve the same performance, because it increased the cognitive load and was controlled processing rather than automatic
What is controlled processing?
-you have to pay attention at all times, requires more cognitive resources
What did the naturalistic driving study show about inattentive driving?
-67% of near crashes involved inattentive driving in 3 seconds prior to event
What is experience sampling?
-in the experiment discussed, they used an app to text participants at random times during the day to ask them to report on a behavior
Why are we so tied to our cell phones?
-operant conditioning and being rewarded for everything
What is continuous partial attention?
-you never fully concentrate on what you’re doing and you break the continuity of what you’re doing
What is mind wandering?
-day dreaming
What is inattentional blindness?
-a stimulus that is not the focus is not perceived even though a person might be directly looking at it, think Hershey kiss under cup
What is inattentional deafness?
-you’re listening to something specific and do not hear other things
What is change blindness?
-if shown two versions of a picture, differences between them are not immediately apparent
What is change blindness called when it is about a film?
-continuity error
What is exogenous attention? Driven by what and top or bottom processes?
-automatic attention to something that makes a noise suddenly or moves unexpectedly, driven by stimulus and bottom-up processes
What is endogenous attention? Driven by what and top or bottom processes?
-deliberately direct our attention from one thing to another, goal driven and top-down
Do both endogenous and exogenous attention have overt attention?
-yes
What is the binding problem? Use an example to describe
-how an object’s individual features are bound together to give a single percept, things like shape, movement, colour etc are processed by different areas of the brain but are still brought together to be perceived as one object like a ball rolling
What is feature integration theories posit by Treisman?
-attention allows us to perceive an objects visual features as belonging together
What are the two stages in feature integration theory? (2)
-pre attentive stage
-focused attention stage
Describe the diagram for Treisman’s feature integration theory.
-an object is first looked at through the pre attentive stage and analyzed into features and then goes into the second stage focused attention stage where we combine the features and then we perceive the object.
What is the preattentive stage?
-automatic, object analyzed into features without effort or attention
