b) If activation in a neuron is not large enough to generate an action potential, no increase in neurotransmitter release from that neuron will be observed c) When an action potential arrives at the end of a neuron, it initiates a release of neurotransmitter substance into the synaptic cleft d) Myelin around axons causes action potentials to travel rapidly - correct answer Action potentials in a neuron can be smaller or larger, depending on the number of presynaptic cells synapsing on the dendrites of that neuron, and the strength of the signal from those presynaptic cells Dendrites on neurons do ________; they do not _________: a) collect excitatory and inhibitory potentials; transmit action potentials b) transmit action potentials; collect excitatory and inhibitory potentials c) make electrical contacts with other neurons; make chemical contacts with other neurons d) collect action potentials; collect excitatory and inhibitory potentials - correct answer collect excitatory and inhibitory potentials; transmit action potentials
d) It will either produce an action potential or not, depending entirely upon whether it is an excitatory or inhibitory neuron - correct answer It will integrate the incoming excitatory and inhibitory signals, with its rate of action potentials depending on the relative amount of each type of signal Which of the following is NOT true about sleep: a) As you transition through the stages of sleep from stage 4 to stage 2, your neural activity oscillates at faster and faster frequencies b) During stage 4 sleep, your skeletal muscles are almost completely inactive c) Stages 3 and 4 are the deepest stages of sleep, when regular, slow, waves are evident on EEG d) REM sleep happens once per night - correct answer REM sleep happens once per night Distinguishing a severely brain damaged individual as being in a vegetative state, compared to a minimally conscious state, or locked-in state, is: a) difficult since contingences between stimuli and behaviour can be difficult to observe in all three b) impossible - the three states are indistinguishable c) difficult to distinguish minimally conscious and locked-in states because the individual has their eyes open in both, but since eyes are closed in the vegetative state, it's easy to distinguish that one
d) difficult since the individual often doesn't exhibit any behaviour in all three - correct answer difficult since contingences between stimuli and behaviour can be difficult to observe in all three Which of the following is TRUE about visual search tasks? a) Search is serial for conjunctions of features, but parallel for single features b) Search is always conducted in parallel c) Search is parallel for conjunctions of features, but serial for single features d) Search is always conducted in serial - correct answer Search is serial for conjunctions of features, but parallel for single features Evidence for the theory that sleep helps us to consolidate memories comes from research indicating that a) damage to the hypothalamus results in both sleep and memory problems b) students perform better on tests after a good night's sleep c) cells in the hippocampus are activated during learning and again during sleep d) cells in the suprachiasmatic nucleus are active during learning and again during sleep - correct answer cells in the hippocampus are activated during learning and again during sleep
Through their research on human responses to physical stimuli, both Helmholtz and Fechner contributed to the beginning of: a) rationalism b) materialism c) comparative psychology d) psychophysics - correct answer psychophysics If psychology can be defined as the science of behaviour and the mind, why are the data in psychology always drawn from behaviour? a) All of the others b) Behaviour can be observed the mind cannot c) Behaviour can be influenced by physiology but the mind cannot. d) Behaviour can be influenced by the environment but the mind cannot - correct answer Behaviour can be observed the mind cannot
In psychological research, the term generalization refers to a) concluding that the results obtained from a sample can also be applied to the larger population b) adding the results from one study to those from other studies c) obtaining a broad understanding of how different variables are related to each other d) how significant the results of the statistical analysis are - correct answer concluding that the results obtained from a sample can also be applied to the larger population Suppose a researcher finds a correlation between the amount of time university students spend on Facebook (variable A) and the students grades (variable B). The researcher can reasonably conclude: a) that some unknown variable is affecting variable A and variable B b) that variable A influences variable B c) that variable B influences variable A d) none of the above - correct answer none of the above
d) monetary remuneration; prior informed consent - correct answer no forseeable harm; there is a full debriefing Suppose that you conduct an experiment to study the effects of love on improving children's self concepts. To manipulate love, you allow a research assistant to hug each child after he or she has successfully completed a set of math problems. After the study is over, you ask the children if they felt loved during the study. They all say no. Apparently, your operational definition of your independent variable is a) unreliable b) invalid c) too subjective d) not objective - correct answer invalid Mean is to __________ as standard deviation is to __________. a) variability; relations b) central tendency; variability c) descriptive statistics; inferential statistics
d) inferential statistics; descriptive statistics - correct answer central tendency; variability Altruistic behaviour toward non-relatives can be explained by a) Reciprocal altruism b) Inclusive fitness c) Personal fitness d) Nonfamilial altruism - correct answer Reciprocal altruism behaviour whereby an organism acts in a manner that temporarily reduces its fitness while increasing another organism's fitness Intelligence has a heritability estimate of .50 in a North-American Caucasian population. This means that: a) All Caucasian individuals from North America will show a correlation in IQ scores with their adoptive parents' IQ scores of about .50. b) On average, about 50% of the variance in intelligence in any group of people can be explained by genetic inheritance.

d) Variable-ratio, every 5th response reinforced - correct answer Fixed-ratio, every response reinforced As sleep cycles progress over the course of an average night, the amount of time spent in REM sleep: a) becomes 100% (the last few hours of sleep, before regular waking time, are entirely REM) b) Decreases c) Increases d) Becomes zero (i.e. REM eventually drops out of the sleep cycle) - correct answer Increases Skweeky-kleen is one of the largest manufacturers of dishsoap. They'd like to increase their market share by giving consumers more product, in a bigger bottle, for the same price they charge now, but without being wastefully extravagant with their 'giveaway'. You're a consultant psychologist for the company. What is the first thing to do/try? a) don't change anything - just put a 'New Bigger Bottle!' label on the bottle b) determine the difference threshold for bottle size c) tell the company that the proportion by which they'll need to change the bottle size will vary as a function of original bottle size
b) The size of the jnds for sugar is smaller than those for vinegar c) Sugar and vinegar activate different neurons that carry the information to the brain d)The threshold for sour is lower than the threshold for sweet tastes - correct answer Sugar and vinegar activate different neurons that carry the information to the brain When we look at a musician on stage holding a guitar, the guitar typically hides the musician's midsection and part of the left arm. But we ignore the gaps in the contour of the musician's body and perceive it as a complete form anyway. This illustrates: a) figure-ground segregation b) the Gestalt principle of proximity c) illusory contours d) Gestalt principle of closure - correct answer Gestalt principle of closure Phenomena such as blindsight and visual agnosia demonstrate that: a) perceptions can cause behaviour even when we are not aware of them b) conscious perception is always necessary for behaviour to occur c) brain damage does not always cause deficits in perception d) consciousness and perception are unrelated - correct answer perceptions can cause behaviour even when we are not aware of them
Suppose you stared at a blue balloon, then sifted your eyes to a white surface and saw a yellow afterimage of the balloon. This afterimage would be explained by the fact that retinal neurons that respond most to blue-appearing light ____________, while those that respond to yellow-appearing light ___________. a) respond subtractively; respond additively b) continue to respond strongly; add their excitation to that of the "blue" neurons c) became fatigued; still responded strongly d) continue to respond strongly; respond equally strongly - correct answer became fatigued; still responded strongly Visual information is sent via the optic nerve to the __________, which, in turn, sends it to the __________. a) cingulate gyrus; occipital cortex b) thalamus; primary visual cortex c) limbic system; occipital lobe d) hypothalamus; primary visual cortex - correct answer thalamus; primary visual cortex Which of the following does not contribute to our depth perception? a) the density of cones at the fovea
