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)

New cards

Webers law (absolute threshold)

Difference in stimuli and sensation ( difference threshold increase with intensity.. EASIER to tell DIFFERENCE between 4tb and 10 lb weight RATHER than 8lb and 10lb weight

2
New cards

Qualitative Research

Non- numerical, images, words, observations

3
New cards

Experimental Research

Random assignment to groups/ independent variable used.

4
New cards

Independent variable

The characteristics of an experiment that is MANIPULATED or Changed by research

5
New cards

Correlation Relationship

Between two or more VARIABLES ( Genetics and Eating disorder)

6
New cards

Biological approach

Brain and body affects behavior( hormones, neurontransmitters)

7
New cards

Evolutionary approach

Adaption to environment affect behavior ( aversion to spiders)

8
New cards

Charles Darwin theory:

Natural selection: genes passed downy to help evolution and survive (survival of the fittest)

9
New cards

Somatic

MUSCLE 💪movement

10
New cards

Spinal cord

Sends SIGNALS to the body

11
New cards

Refractory system

Neuron rests after firing neurotransmitters

12
New cards

Action potential

Shifts the electrical change of a neuron ( through the Axon it transmits information)

13
New cards

Reuptate

Neurotransmitters are reason by the neuron( prevents to much being transfer

14
New cards

Endorphins

Neurotransmitter that reduces pain in the body

15
New cards

Hypothalamus

Sends signals to the pituitary gland ( regulate body temperature)

16
New cards

Neuroplasticity

Ability to recover form brain injury

17
New cards

Endocrine system

Regulates level of HORMONES

18
New cards

TMS

Measures stage sleep individuals is in

19
New cards

Narcolepsy

Persons FALLS immediately into REM during day without warning

20
New cards

Percibes smell

Olfactory Bulbs

21
New cards

Amygdala

Part of limbic system that process emotions

22
New cards

Case study

Detailed investigations into one individual or small group behavior

23
New cards

Cross- cultural

Looks at how cultural factors influence human behavior

24
New cards

Cross-sectional study

Studying people that are different ages at the same time to see what differences can attributed.

25
New cards

What par of the brain affects memory?

temporal lobe

26
New cards

What part controls my walking?

Cerebellum

27
New cards

What part of the brain affects grow?

Pituitary gland

28
New cards

Consolidation Theory

Memories are not permanent after they are formed BUT require time and stabilization to become lasting( ex: be consistent with )

29
New cards

The process that primarily responsible for regulating-sleep wake cycle?

The suprachiasmatic nucleus (SCN) in the brain hypothalamus plays a key role in adjusting the melatonin.
