Unit 1 - Introduction & Neuroscience and Biological Foundations Flashcards
Socio-cultural paradigm
behavior is a result of our environment and culture
Psychoanalytic/psychodynamic paradigm
behavior is a result of childhood and drive to fulfill unconscious desires (Freud)
Cognitive paradigm
behavior is a result of mental processes, thoughts, beliefs, perceptions
Humanistic paradigm
behavior is a result of effects to fulfill needs in the best way we can
Behavioral paradigm
behavior is a result of rewards; we stop acting in ways that are punished
Biological paradigm
behavior is a result of brain structure, body chemistry, hormones, genetics
Evolutionary paradigm
behavior is a result of natural selection and adaption
4 lobes of the brain
frontal lobe, parietal lobe, temporal lobe, occipital lobe
Frontal lobe
includes: prefrontal cortex (personality/emotion and higher brain function), medial prefrontal cortex and orbitofrontal cortex (strong connections to limbic system), motor cortex (voluntary movements), broca’s area (smooth and fluent speech)
function: higher cognitive function including planning, personalities, memory storage, complex decision making, language
Temporal lobe
includes: amygdala (fear response and processing emotions), primary auditory cortex (processes auditory info), auditory association area (identifies auditory info from ears), Wernicke’s area (language comprehension)
function: perception, face recognition, object recognition, memory acquisition, understanding language, and emotional reactions
Parietal lobe
includes: somatosensory cortex (sensory processing and integration)
function: integrates info from senses to create picture of the world
Occipital lobe
includes: primary visual cortex (receives and processes info from optic nerves), visual association cortex (identifies visual info from eyes)
function: vision
Limbic system
includes: thalamus (relay station for incoming sensory info), hypothalamus (the 4 F’s), hippocampus (forms long-term memories), amygdala (fear response and processing emotions), cingulate cortex (emotional/cognitive processing)
function: emotions, motivation, memory, learning
Association areas
neurons in cortex that make connections between sensory info and stored memories/images/knowledge
Spatial neglect
people who have a damaged right hemisphere and ignore everything in left visual field
Roger Sperry
pioneer in field of hemisphere specialization; proved that left and right hemispheres specialize in different functions and activities
Left hemisphere
language, speech, handwriting, math, sense of time and rhythm, thought requiring analysis
Right hemisphere
perception, visualization, spatial perception, recognition of patterns/faces/emotions/melodies, expression of emotions, comprehends simple language BUT doesn’t produce speech
ADHD
developmental disorder involving behavioral and cognitive aspects of inattention, impulsivity, hyperactivity (cortical and subcortical areas involved –> prefrontal cortex, basal ganglia, cerebellum, corpus callosum)
Connectivity in brain
pons (bridge between cerebrum and cerebellum, balance, motor control, posture), corpus callosum (connects left and right hemispheres), thalamus (relay station for incoming sensory info)
movement in brain
cerebellum, motor cortex
basic body functions in brain
medulla (regulates life-sustaining functions), hypothalamus
sensory in brain
reticular formation (allows people to ignore constant unchanging info and become alert to changes in info), parietal lobe
Brain stem
includes: medulla, pons, reticular formation
emotions in brain
limbic system
speech in brain
Broca’s area
