Question 9 The goals of preprocessing are to: 1 / 1 point All of these options Check statistical assumptions and transform the data to meet assumptions. Standardize the locations of brain regions across subjects to achieve validity and sensitivity in group analysis. Minimize the influence of data acquisition and physiological artifacts. —————————————————————————- 11. Question 11 A design that crosses two experimental variables with two more levels each is a: 1 / 1 point Parametric modulation design Factorial design All of these options None of these options —————————————————————————- 13. Question 13 Which of the following are benefits of normalization? 1 / 1 point Reduces spatial resolution. Results can be generalized to larger population AND voxel-wise analysis is possible across individuals Voxel-wise analysis is possible across individuals Results can be generalized to larger population —————————————————————————- 15. Question 15 Which of the following are benefits of smoothing? 1 / 1 point Both of these options None of these options May overcome limitations in the normalization by blurring any residual anatomical differences. May increase the validity of the statistical analysis. —————————————————————————- 10. Question 10 The experimental design shown below an example of ________ design? 1 / 1 point a blocked none of these options an event-related —————————————————————————- 14. Question 14 Which of the following are benefits of co-registration? 1 / 1 point Both of these options Allows one to visualize single-subject task activations overlaid on the individual’s anatomical information. Simplifies later transformation of the fMRI images to a standard coordinate system. Neither of these options —————————————————————————- 12.
