Ch.5 Perception Flashcards
What is Gate Control Theory?
One type of pain can block the experience of another pain
Define Perception of Pain
More Distraction = less pain
More Anxious = more pain
More Control = less pain
Interpretation - how you interpret/ influence pain
What is ADHD and name the types
Attention Deficit Hyperactivity Disorder
Types: Inattentive and Hyperactive
Inattentive type of ADHD
Struggle with maintaining focus, concentration. Easily distracted, difficult to finish projects. Sometimes called “ADD”
Hyperactive ADHD
When a person is impulsive, restless, can’t stay still, often blurt out answers, can’t wait their turn
Treatment for ADHD
Stimulant, works on part of the brain that controls impulsivity, concentration (ex. Ridalen)
Structure (discipline, providing limits)
Figure/Ground Perception
Your ability to see what’s the foreground and what’s the background. It’s inborn
Name the Principles of Formation of Figures
Principle of Nearness, Similarity, and Closure
Define the Principle of Nearness
Stimuli that are near each other, grouped together
Define the Principle of Similarity
Objects/stimuli that are similar to each other, grouped together
Define the Principle of Closure
When you look at something that’s incomplete, you tend to make/see it complete
Define Depth Perception
Your ability to judge distances.
Partially inborn and learned
Explain the Visual Cliff experiment
Experiment how depth of perception is in born - baby on clear table, once gets near the middle or towards edge, stops, doesn’t keep going; thinks its edge
Moon Illusion
When the moon tends to look larger when the moon is on the horizon than when the moon is directly overhead.
Moon looks larger on horizon due to other objects around/in the same direction
Frame of Reference
A comparison.
Ex. 10yo says middle age is 30, while 70yo would says middle age is 50
Orientation Response
What’s goes on when you first notice a stimuli.
Pupils enlarge, brainwave pattern changes, increase blood flow in brain, blood pressure increases
What are the Factors of Attention?
- The more Intense the stimuli, the more you notice
- The more the stimuli is Repeated, the more you notice
- The more Motivated you see a stimuli, level of motivation affects what you see/notice
Define Habituation
Become habituated/accustomed to stimuli, after first noticing stimuli
Define Perceptual Expectany
This idea if you expect to see things a certain way, you’re more likely to see it that way (Rosenthal & Rosehan)
Define Subliminal Messages
Subliminal means beneath or below consciousness.
Unconscious mind can accept an idea and will influence your conscious choices
Eyewitness Testimony
Consistently unreliable, people tend to see what they expect to see, your own past learning will influence what you see, the confidence of the witness has nothing to do with the accuracy
