The type of t-test examines differences for within-subjects designs.
What is a paired t-test?
100

These are the 4 goals of scientific research.
What are describe, predict, determine causes and explain mechanisms?
100
Aharoni et al. concluded that activation in this region predicted re-arrest.
What is the ACC?
200
Ullsperger et al. (2005) used larger stimulus set in their flanker experiment in order to eliminate this confound, however, they created this different confound.
What is stimulus repetition and contingency learning biases?
200
The degree to which individuals within the sample differ from the sample mean.
What is the standard deviation?
200
This technique is necessary in order to use selective averaging to examine data from rapid event-related designs.
What is equating the overlap?
200
Using this type of fMRI design allows one to randomize trial presentation across conditions AND better estimate the magnitude of each trial relative to baseline.
What is a jittered event-related design?
200
This fMRI design utilizes the reduction in activation the second time a stimulus is presented in order to do what?
What is fMRI adaptation and what is to identify distinct populations of neurons within a voxel?
300
These authors concluded that reduced ACC activity on iI vs. cI trials reflected reduced conflict.
Who is Botvinick et al. 1999? Or Kerns et al.
300
This is the most stringent method of correcting for multiple comparisons.
What is Bonferroni correction?
300
Name one problem with using selective averaging to analyze fMRI data.
What is 1) unable to correct for noise, 2) must equate the overlap, and 3) cannot use when pure insertion assumption is violated.
300
__________ experimental design is used to test whether the assumption of pure insertion is violated, where ____________ experimental design may be used to avoid violating the assumption of pure insertion.
What is factorial design? What is parametric design?
300
This standard requires that scientific evidence must be generally accepted within its own scientific field.
What is the Frye standard?
400
According to the Colcombe et al. (2004), exercise had this effect on ACC activity during a flanker task.
What is reduced?
400
RESELs are the unit analysis in this method.
What is Gaussian random field theory?
400
This method of correcting for multiple comparisons is used when the researchers have a specific area of the brain they hypothesize to be important.
What is region of interest analysis?
400
In this type of fMRI design it is difficult to estimate the baseline.
What is a rapid, unjittered event-related design?
400
This is the correct order of fMRI preprocessing steps.
What is slice timing, realignment, coregistration, normalization, smoothing?
500
Kerns et al. (2004) found that activity in these 2 brain regions was related to behavioral adjustments on the Stroop task.
What is the ACC and PFC?
500
This type of error, also called a false positive, occurs more frequently as the statistical threshold _______.
What is type I and increases?
500
The name of the incorrect interpretation used in fMRI data for when activity in a brain region within one task is generalized to other tasks that have also shown activity in that brain region.
What is reverse inference?
500
A researcher interested in conducting the Stroop task in an fMRI experiment would be advised to use this type of design.
What is event-related?
500
The fMRI design has been used to develop technology to assist individuals who are paralyzed.
