Explaining Behavior: Level-Of-Analysis Approach

1. When explaining behaviour, the levels-of-analysis approach considers the _________, ___________, and _________ perspectives.
A. pre-event; event; post-event
B. antecedent; behavioural; consequential
C. biological; psychological; environmental D. developmental; biological; humanistic
2. The synapse is a:
A. location in the neuron where neurotransmitters are packaged into vesicles.
B. tiny area on the tip of the dendrite of the next neuron.
C. large area where neurotransmitters are released.
D. tiny gap between the axon terminal of a neuron and the dendrite of the next neuron.
3. A hypothesis is best considered as a(n):
A. tentative explanation or prediction about some phenomenon.
B. attempt to explain something after it has already occurred.
C. set of formal statements that explain how certain events are related to one

directly observable behaviours and internal states and processes.
16. When the researcher observes behaviour as it occurs in a normal or typical setting, she is using _______________.
A. survey research
B. a case study
C. correlational research D. naturalistic observation
17. The all-or-none law of neural conduction suggests that:
A. all neurons have action potential thresholds but none of them are the same threshold.
B. if the action potential threshold is just met, a weak action potential will occur whereas if the action potential threshold is exceeded, a more intense action potential will occur.
C. once the action potential threshold is met an action potential of uniform and maximum intensity occurs.
D. once an action potential has occurred the neuron will either take all or none of the refractory period time before firing another action potential.
18. A neuron sends an action potential to the muscle that contracts your eyelid. This neuron would be classified as a(n) __________________ neuron.
A. excitatory
B. action
C. sensory D. motor
19. The nucleus of the neuron and the biochemical structures needed for cell survival are contained in
