Unit 1 Review
1. Senses
a. Visual - I can see it
b. Tactile - I can feel/touch it
c. Gustation - I can taste it
d. Auditory - I can hear it
e. Olfaction - I can smell it
f. Kinesthesia - sense position/movement of the body without vision (eyes closed)
Weber’s Law: (absolute threshold) - Difference in stimuli and sensation (difference threshold increases with intensity... easier to tell the difference between 4lb and 10lb weight rather than 8lb and 10lb weight)
2. Research Designs
a. Qualitative Research: non-numerical data (images, words, observations)
b. Quantitative Research: actual data (numbers, percentages, mathematical model)
c. Experimental Research: random assignment to groups/independent variables used
d. Correlation: Relationship between two variables (Genetics and Eating disorders)
3. Psychological Perspectives
a. Biological Approach: brain and body affect behavior (hormones, neurotransmitters)
b. Evolutionary Approach: adaptation to environment affects behavior (aversion to spiders)
i. Charles Darwin’s natural selection: genes passed down to help survive (survival of the fittest)
c. Cognitive: thinking influences behavior
d. Humanistic: focus to be the best
e. Psychodynamic: importance of childhood events
4. Nervous System
a. Somatic - muscle movement
b. Sympathetic - “fight or flight” (dilated pupils, reduced digestion, increased heart rate)
c. Parasympathetic - cool down phase after excitement
d. Spinal cord - sends signals to body (hand on a hot plate)
5. The Brain
a. Refractory Phase: Neuron rests after firing neurotransmitters
b. Action Potential: shifts in electrical charge of a neuron (across the axon)
c. Endorphins: Neurotransmitter that reduces pain in the body
d. Dopamine: Neurotransmitter that increases pleasure in the body
e. Hypothalamus: sends signals to the pituitary gland (regulates body temperature)
f. Neuroplasticity: ability to recover from brain injury
g. Broca’s Area: Controls speech (if damaged, will cause speech issues)
6. Endocrine System
a. Regulates level of hormones in the body
7. Sleep
a. EEG: measures electrical currents in the brain
b. TMS: measures the stage of sleep an individual is in
c. Circadian Rhythm: sleep/wake cycle (will not feel rested if disrupted)
