Answers GRADED A+
1. Absolute threshold
- ANS - The minimum stimulus intensity required to
activate a sensory receptor 50% of the time.
2. Difference threshold (JND)
- ANS - The minimum noticeable difference between two
sensory stimuli 50% of the time.
3. Weber's law
- ANS - States that two stimuli must differ by a constant
proportion for difference to be perceptible.
4. Spotlight model
- ANS - Visual attention can shift within the visual field
but can only be focused on a single target.
,5. Phonological loop
- ANS - A component of working memory that allows us to
repeat semantic verbal or written information to help us
remember it.
6. Visuospatial sketchpad
- ANS - A component of working memory that allows us to
use mental imagery to help us remember semantic visual
information.
7. Episodic buffer
- ANS - A component of working memory that interacts
with information in long term memory.
8. Assimilation
- ANS - The conformation of experiences into existing
schemas.
9. Accommodation
- ANS - The adjustment of a schema to take into account
new experiences.
10. Confirmation bias
- ANS - The tendency to search for information that
confirms preconceived thinking.
,11. Fixation
- ANS - Inability to see a problem from a fresh
perspective.
12. Mental set
- ANS - A tendency to fixate on solutions that have
worked in the past but may not apply to the current
situation.
13. Functional fixedness
- ANS - A tendency to perceive the functions of objects as
fixed and unchanging.
14. Representativeness heuristic
- ANS - A tendency to judge the likelihoods of an event
occurring as based on our typical mental representations
of those events.
15. Availability heuristic
- ANS - A tendency to make judgments based on how
readily available information is in our memories.
, 16. Belief bias
- ANS - The tendency to judge arguments based on what
one believes about their conclusions rather than the use
of sound logic.
17. Belief perseverance
- ANS - A tendency to cling to beliefs despite the presence
of contrary evidence.
18. Awake
- ANS - Alpha/beta (relaxed) waves, low amplitude, 8-12
Hz.
19. Stage 1
- ANS - Theta waves, low amplitude, 3-7 Hz.
20. Stage 2
- ANS - K-complexes/sleep spindles, moderate amplitude,
12-14Hz bursts.
21. Stage 3
- ANS - Delta waves (slow wave sleep), high amplitude,
0.5-3 Hz.
