PSY 2012 CORE MAIN EXAMS ALL SET QUESTIONS
AND ANSWERS SURE A+
✔✔demand characteristics - ✔✔cues that participants pick up from a study that allow
them to generate guesses regarding the researcher's hypothesis
✔✔informed consent - ✔✔informing research participants of what is involved in a study
before asking them to participate
✔✔statistics - ✔✔application of mathematics to describing and analyzing data
✔✔descriptive statistics - ✔✔numerical characterizations that describe data
✔✔central tendency - ✔✔measure of the "central" scores in a data set, or where the
group tends to cluster
✔✔mean - ✔✔average; a measure of central tendency
✔✔median - ✔✔middle score in a data set
✔✔mode - ✔✔most frequent score in a data set; a measure of central tendency
, ✔✔range - ✔✔difference between the highest and lowest scores
✔✔Variability - ✔✔measure of how loosely or tightly bunched scores are
✔✔standard deviation - ✔✔measure of dispersion that takes into account how far each
data point is from the mean
✔✔inferential statistics - ✔✔mathematical methods that allow us to determine whether
we can generalize findings from our sample to the full population
✔✔Neuron - ✔✔Nerve cell specialized for communication
✔✔Dendrite - ✔✔portion of the neuron that receives signals
✔✔axon - ✔✔portion of the neuron that sends signals
✔✔synaptic vesicle - ✔✔spherical sac containing neurotransmitters
✔✔Neurotransmitter - ✔✔chemical messenger specialized for communication from
neuron to neuron
✔✔Synapse - ✔✔space between two connecting neurons through which messages are
transmitted chemically
✔✔synaptic cleft - ✔✔a gap into which neurotransmitters are released from the axon
terminal
✔✔resting potential - ✔✔electrical charge difference across the neuronal membrane,
when the neuron is not being stimulatd or inhibited
✔✔Threshold - ✔✔membrane potential necessary to trigger an action potential
✔✔Action potential - ✔✔electrical impulse that travels down the axon triggering the
release of neurotransmitters
✔✔Receptor site - ✔✔location that uniquely recongnizes a neurotransmitter
✔✔reuptake - ✔✔the synaptic vesicle reabsorbs the neurotransmitter
✔✔endorphin - ✔✔chemical in the brain that plays a specialized role in pain reduction
✔✔plasticity - ✔✔ability of the nervous system to change
