Question | Answer |
---|---|
Experimental group | test subjects who were selected to participate in an experiment |
Researcher Bias | whenever there is a flaw in a survey’s research design |
Behavior | what can be observed |
Structuralism | inside the mind-asking what is there? |

Natural Selection/Evolutionary Perspective | process in where only the strong survive |
Biological Perspective | focus on brain and nervous system |
Behavioral Perspective | all behavior was determined by stimuli in the environment |
Mental Processes | thoughts, feelings, motives we have privately cannot be observed |
psychodynamic process | Emphasizes unconscious thought, conflict between biological drives like sex, societies demand early family experiences. |
Cognitive perspective | that focuses on mental processes, perception, and language as a way of explaining and understanding human behavior. |
Humanistic Perspective | typically holds that people are inherently good, and encourages the viewing of the self as a "whole person" instead of the sum of one's parts. It encourages self-exploration as opposed to the study of behavior in other people. |
Socio-cultural perspective | the scientific study of how people's thoughts, feelings and thus behaviors are influenced by actual, implied or imagined presence of others and the environment around them. |

serotonin- 5-HT | Happy chemical - low= depression high=violent aggressive behavior, mood stabilizer!!!!!!! 90% serotonin comes from food! |
edorphins | Natural Pain killers |
Oxytocin | love & bonding- uterine contractions bfeed and labor |
limbic system | set of brain structures including the hippocampus and amygdala and anterior thalamic nuclei and a limbic cortex that support a variety of functions including emotion, behavior and long term memory. |
hippocampus | memory |
amygdala | fear and discrimination for organisms survival |
cerebellum | motor coordination |
medulla | breathing and reflexes |
pons | sleep and arousal |
nature vs nurture | Nature is often defined in this debate as genetic or hormone-based behaviors, while nurture is most commonly defined as environment and experience. |
genotype | what u inherited-genotype of an organism is the genetic code in its cells |
phenotype | visible or expressed trait, such as hair color- what u look like outside- also be enviromental |
hypothalamus | eating, drinking, sex- plays role emotion and stress |
mirror neurons | sparks brain activity in the same place as when we are watching someone else doing the activity |
dominant-recessive gene principle | if one gene of a pair is dominant and the other is recessive, the dominant gene exerts its effect, overriding the potential influence of the recessive gene |
electrochemical transmission- | start as electro change to neurotransmitter |
synaptic transmission | 1.electric impulse is converted into chemical 2.axon release into neuro trans gap 3. dendrite receptor site detects neuro then restart |
adaptability/plasticity | change in the brains neural structure to enable adjustment to experience, to compensate for lost function and also to maximize remaining functions in the event of brain injur |
mri | Magnetic resonance imaging is a medical imaging technique used in radiology to form pictures of the anatomy and the physiological processes of the body |
CT-cat scan | Computed tomography- produces multiple images or pictures of the inside of the body. The cross-sectional images generated during a CT scan can be reformatted in multiple planes, and can even generate three-dimensional images. |
PET | sugar an image made using positron emission tomography, especially one of the brain. |
fmri | Functional magnetic resonance imaging or functional MRI (fMRI) measures brain activity by detecting changes associated with blood flow |
lobes of brain | occipital, frontal, temporal, parietal |
Occipital brain lobe | eyes/vision |
frontal brain lobe | intelligence, decisions, personality |
temporal lobe brain | hearing speech language memory |
parietal brain lobe | balance, spatial location |
sensation | what we feel/smell/see/taste hear |
perception | interpretation of sensation |
bottom up | related to sensation- new experinece |
top-down | related to perception- past experience |

noise | anything that disrupts- sounds/stress/worries |
absolute threshold | smallest amount of intensity from a stimulus that is detected by a person's senses 50% time |
difference threshold | minimum difference in stimulation that a person can detect 50 percent of the time |
subliminal perception | Subliminal messages and perception are linked to the idea of mind contro |
webers law | 2 stimuli must differ by constant proportion to be conceived as different low levels stimulation- small changes can be noticed, large levels stimulation large simulation to notice |
