psych 1 Flashcards
in an experiment, the variable that is manipulated in some way is called the:
independent variable
the variable that is measured to find out the effects of the experimental treatment is called:
dependant variable
what is a hypothesis
a prediction
the main purpose of ethical guidelines is to:
protect the welfare of research participants
visual info in the brain is sent to the
occipital lobe
the left hemisphere of the brain is used for tasks like
reading and writing
the brain might not work effectively due to reasons such as
brain tissue damage, neurons not communicating well, brain chemicals not working properly
the four lobes of the brain
temporal, frontal, occipital and parietal
what is the cerebellum and its role
a structure located at the back of the brain responsible for movement and balance
what is the role of the frontal lobe
higher order thinking, personality, emotional regulation, decision making, voluantary movement
what is the role of the temporal lobe
processes sound auditory info, comprehends speech and plays a role in language
what is the role of the occipital lobe
recieves and processes visual info
what is the role of the parietal lobe
reviews and processes sensory info such as touch and temperature
what are key functions of the left hemisphere
controls right side of the body, muscle movement, verbal tasks, analysis, logic and reasoning
what are the key functions of right hemisphere
controls the left side of the body, muscle movement, non-verbal tasks, spatial and visual thinking, creativity and imagination
what is the cerebral cortex
the large, wrinkled structure that covers most of the brain, it consist of 4 lobes, stores memories, responsible for conscious thought
dendrites
receives neural info from previous neuron
cell body
houses the nucleus
nucleus
powers the cell
axon
a long tubular structure that transports the action potential
mylein sheath
protects the axon from other axons
axon terminals/buttons
structures at the end of a neuron, that sends the signal to the neat neuron
rights of the participants in regards to the ethical principles of psych
confidentiality, withdrawal rights, voluntary participation
what might happen to someone who has suffered a traumatic brain injury to their left temporal lobe
they may suffer from hearing loss, difficulties forming words when talking, memory problems, especially memory of language
