Psychology 1000 Exam questions
and answers graded A+
Neurotransmitters - ANS✅✅Chemical substances stored in tiny sacs within terminal buttons;
transmit info across synaptic gap to next neuron
Acetylcholine - ANS✅✅The neurotransmitter that stimulates the firing of neurons; actions of
muscles, learning, and memory
Dopamine - ANS✅✅Neurotransmitter that controls VOLUNTARY movement and affects sleep,
mood, attention, and learning
Ex: failure of the proper function of the neuron can result in Parkinson's Disease
Serotonin - ANS✅✅Neurotransmitter involved in the regulation of sleep, MOOD, attention, and
learning
GABA - ANS✅✅Neurotransmitter that keeps neurons from firing and helps control the precision of
the signal being carried; present in the brain (CNS)
Resting Potential - ANS✅✅The stable, negative charge of an inactive neuron
Action Potential - ANS✅✅The brief wave of positive electrical charge that sweeps down axon
All-or-Nothing - ANS✅✅Once the electrical impulse reaches a certain level of intensity (threshold),
it fires and moves all the way down the axon without losing any intensity
Neural Networks - ANS✅✅Networks of nerve cells integrate sensory and motor output
Neurons - ANS✅✅Nerve cells that handle the information processing function
Axon - ANS✅✅Part of neuron that carries info AWAY from cell body award other cells
, Dendrites - ANS✅✅Part of neuron with tree like fibers; receives info and orients it towards the cell
body
Myelin Sheath - ANS✅✅Part of neuron that insulates neuron; speeds up transmission of nerve
impulse
Synapse - ANS✅✅Tiny spaces between neurons: between axon of one neuron and dendrites of
another
Terminal Buttons - ANS✅✅The end of an axon; hold neurotransmitters; sends info
Frontal Lobe - ANS✅✅Lobe behind forehead; contains personality, intelligence, and controls
VOLUNTARY muscles
Parietal Lobe - ANS✅✅Lobe involved in registering spatial location, attention, and motor control
Temporal Lobe - ANS✅✅Lobe involved in hearing, language processing, and memory
Occipital Lobe - ANS✅✅Lobe at BACK of head; controls response to visual stimuli
Infant Attachment - ANS✅✅Close emotional bond between an infant and its caregiver
Insecure Attachment - ANS✅✅When a baby avoids the mother or is ambivalent to her
Secure Attachment - ANS✅✅The ways that infants use their caregiver, usually their mother, as a
secure base from which to explore the environment
Accommodation
*Piaget* - ANS✅✅Occurs when an individual adjusts their schemas to new info
Ex: Older infant selectively sucks bottles and not toys
Assimilation
*Piaget* - ANS✅✅Occurs when individuals incorporate new info into existing knowledge
