subjects are assigned to each group o carryover effect 0 p 170 O a problem that may occur in repeated measures designs if the effects of one treatment are still present When the next treatment is given 0 confounding variable 0 p 162 O a variable that is not controlled in a research investigation 0 in an experiment the experimental groups differ on both the independent variable and the confounding variable 0 counterbalancing o p 171 O a method of controlling for order effects in a repeated measures design by either including all orders of treatment presentation or randomly determining the order for each subject 0 fatigue effect 0 p 170 O deterioration in participant performance With repeated testing 0 independent groups design betweensubjects design 0 p 168 0 an experiment in which different subjects are assigned to each group 0 internal validity o p 163 O the certainty With Which results of an experiment can be attributed to the manipulation of the independent variable rather than to some other confounding variable 0 latin square 0 p 172 O a technique to control for order effects Without having all possible orders 0 matched pairs design o p 174 O a method of assigning subjects to groups in which pairs of subjects are rst matched on some characteristic and then individually assigned randomly to groups mortality 0 p 166 O the loss of subjects Who decide to leave an experiment 0 mortality is a threat to internal validity When the mortality rate is related to the nature of the experimental manipulation order effect 0 p 170 O in a repeated measures design the effect that the order of introducing treatment has on the dependent variable posttestonly design 0 p 163 O a true experimental design in Which the dependent variable posttest is measured only once after manipulation of the independent variable practice effect learning effect 0 p 170 O improvement in participant performance With repeated testing pretestposttest design 0 p 164 O a true experimental design in Which the dependent variable is measured both before pretest and after posttest manipulation of the independent variable random assignment 0 p 168 use of a random chance procedure such as a random number generator or coin toss to determine the condition in Which an individual will participate repeated measures design Withinsubjects design 0 p 168 0 an experiment in Which the same subjects are assigned to each group selection differences 0 p 164 O differences in the type of subjects Who make up each group in an experimental design 0 this situation occurs When participants elect Which group they are to be assigned to solomon fourgroup design 0 p 166 0 experimental design in which the experimental and control groups are studied with and without a pretest O withinsubjects design repeated measures design 0 p 168 0 an experiment in which the same subjects are assigned to each group Chapter 9 p 179200 behavioral measure 0 p 187 0 direct observations of behaviors 0 measurements of an almost endless number of behaviors are possible ceiling effect 0 p 189 0 failure of measure to detect a difference because it was too easy confederate o

doubleblind experiment 0 p 193 O a procedure wherein both the experimenter and the participant are unaware of whether the participant is in the experimental treatment or the control condition electroencephalogram o p 187 O EEG O a measure of the electrical activity of the brain electromyogram o p 187 O EMG O a measure of the electrical activity of muscles including muscle tension

measure to help disguise the true purpose of the measure floor effect 0 p 189 0 failure of a measure to detect a difference because it was too difficult O ceiling effect functional MRI 0 p 188 O magnetic resonance imaging uses a magnet to obtain scans of structures of the brain 0 functional magnetic resonance imaging fMRI provides information on the amount of activity in different brain structures Galvanic skin response 0 p 187 o GSR O the electrical conductance of the skin which changes when sweating occurs manipulation check 0 p 195 O a measure used to determine whether the manipulation of the independent variable has had its intended effect on a subject manipulation strength 0 p 185 O a strong manipulation maximizes the differences between the two group s and increases the chances that the independent variable will have a statistically signi cant effect on the dependent variable MRI p 188 provides an image of an individual s brain structures allows scientists to compare the brain structure of individuals with a particular condition physiological measure 0 p 187 O recordings of responses of the body 0 examples galvanic skin response GSR electromyogram EMG and electroencephalogram EEG pilot study o p 194 O a smallscale study conducted prior to conducting an actual experiment designed to test and re ne procedures placebo group o p 191 O the control for the possibility that the administration of a pill injection etc may be suf cient to cause an observed improvement in behavior 0 participants in the placebo group receive a pill or injection containing an inert harmless substance 0 they do not receive the durge given to members of the experimental group selfreport o p 186 O can be used to measure attitudes liking for someone judgments about someone39s personality characteristics intended behaviors emotional states attributions about why someone performed well or poorly on a task con dence in one s judgments and many other aspects of human thought and behavior sensitivity 0 p 189 O the ability of a measure to detect differences between groups singleblind experiment 0 p 193 O the participant is unaware of whether a placebo or the actual drug is being administered staged manipulation o p 183 0 event manipulation 0 when an event is staged during the experiment in order to manipulate the independent variable successfully straightforward manipulation o p 1 8 1 O manipulate variables with instructions and stimulus presentations 0 stimuli may be presented verbally in written form via videotape or with a computer
