COGSCI 115 UPDATED Exam Questions
and CORRECT Answers
Blackwell and Dweck: Study 1 results - CORRECT ANSWER --students mainly minority
--exp group with special module on how intelligence can be improved showed more
improvement in grades/skills and worked harder
--ex of growth mindset
--those with cultural reasons to be anxious were most affected by message (girls & maths)
programs to develop growth mindsets are most beneficial in students with ___ - CORRECT
ANSWER low socioeconomic status or academically at risk
low income vs wealthier peers (growth mindset) - CORRECT ANSWER low income who
exhibit growth mindset show academic performance as high as that of fixed mindset from higher
income brackets
correlation between happiness and __ __ is one of the strongest findings - CORRECT
ANSWER social relationships (social support for college students, even providing instead
of receiving)
cell - CORRECT ANSWER individual neurons
tissue - CORRECT ANSWER nerves, ganglia
organ - CORRECT ANSWER brain and spinal cord
system - CORRECT ANSWER nervous system
levels of organization - CORRECT ANSWER cell, tissue, organ, system
, cell body (or soma) - CORRECT ANSWER the cell's life support center
dendrite - CORRECT ANSWER a branched, treelike structure attached to the soma of a
neuron; receives information from the terminal buttons of other neurons
axon - CORRECT ANSWER the extension of a neuron, ending in branching terminal
fibers, through which messages pass to other neurons or to muscles or glands
terminal button - CORRECT ANSWER the bud at the end of a branch of an axon; forms
synapses with another neuron; sends information to that neuron
neurotransmitter - CORRECT ANSWER a chemical that is released by a terminal button;
has an excitatory or inhibitory effect on another neuron
myelin sheath - CORRECT ANSWER A layer of fatty tissue segmentally encasing the
fibers of many neurons; enables vastly greater transmission speed of neural impulses as the
impulse hops from one node to the next.
myelin sheath and screen time - CORRECT ANSWER 3-5 yr olds with higher screen time
has lower measures of myelination and scored lower on cognitive tests
axons have tow potentials - CORRECT ANSWER resting potential and action potential
resting potential - CORRECT ANSWER the state of the neuron when not firing a neural
impulse, -70mV, Na+ and Cl- outside, K+ and A- inside, occurs because of ions located inside
and outside cell
action potential - CORRECT ANSWER a neural impulse; a brief electrical charge that
provides basis for sending info along axon
--Na+ rush in through sodium channels, inside becomes positive from charged ions
