PSYC/SOC - Senstion and Perception Flashcards
absolute threshold is the lowest intensity that we can ___
detect
difference threshold is he abilty to differentiate at least __% of the time
50%
Weber’s law states that the change required to meet the differenece threshold is a constant fraction of the original stimulus, and that amount of change needed to reach this threshold depends upon the original stimules. Chand(I)/I=k
High K means ____ sensitivity
low
Low K means ___ sensitivity
high
the stronger the stimulus, the more the stimulus needs to be increased before one notices
Gestalt principles describe how we distinguish stable objects from their backgrounds, and from other objects. Top down processing is used to group sensory information into distinct regions called ____
forms
Forms are distinct regions that we group together
The ‘ground’ is what we are not paying attention to
Figure ground principle
a human’s ability to visually differentiate between an object and its background.
Gestalt need to know: top down, continuation, closure, and figure and ground
oculomotor cues is where the brain senses motor movement from the muscles in our eyes. This is a way that we can judge distance without using retinal disparity

most
Broadbent’s early selection theory means it is immediately _____.
filtered
Deautch Late selection theory is like being at a coffee shop and waiting for your name to be called out
Attenuation theory is when only info with high priority makes it to concious processing
Change blindness is when things change in your field of view and you don’t notice
distal stimulus is ___ a part of your body. A proximal stimulus occurs within your brain
not
distal causes the proximal
Declarative memory is remembering facts or events, Non-declarative memor is unconcious memory of how to do things.
phonological loop is when you sign those words for a two factor auth to yourself to remember it!
Working memory can hold 7(+/-2) bits of information at one time
Working memory can hold ____ bits of information at one time
7(+/-2)
The dual coding effect states that humans can have multiple representations of the same idea (the word referring to a dog, the mental picture of a doc, etc.)
Semantic memory are memories of meaning and general knowledge, ability to recall. It is general knowledge. Does this decline or improve with aging?
improve
Processes that remain stable despite aging are …
implicit memory (type of procedural) and recognition of information (multiple choice)
Long term potentiation (LTP) is the molecular process involved in strengthening synapses. The _____ plays the largest role in LTP
hippocampus. Think Hippo on Campus - taken all the classes at Uni!!
circling around and trying to find it like trying to remember the name of a TSwift song is called _____ activation
spreading activation

7-11
Inductive reasoning is the ability to derive general concepts from ___ situations. This is in the concrete operational ages (7-11)
specific
Conservation is the ideas that things stay the same size despite their container shape. This is in the concrete operational stage
think about the video of the girl and the two glasses of blue juice and the coins in a row
Concrete operation has inductive reasoning and and conservation.
