We used a within subject design with every subject performing all three parallel tasks, but with a different order.
In order to test this hypothesis, we additionally obtained, for each picture, the total distance covered by raw eye-gaze movements (unprocessed for fixations) from one gaze datapoint to another, and the proportion of consecutive eye-gaze movements that were between objects and backgrounds, within objects, and within backgrounds, for every subject.
Scaling using the resting state fluctuation of amplitude (RSFA) and breath-hold (BH), which minimizes BOLD variation due to vascular origins, reduced the within-subject BOLD variability in every subject during both tasks but significantly reduced BOLD variability across subjects only during the block design task.
"Why do we have to learn this?" we whined in every subject within ten minutes of starting the lesson, "what use will this be in the real world?" While other subjects were staunchly defended at school, RE was always seen as a tertiary subject.
The difference between the main analysis and the propensity analyses appears to be due to the relatively small LIS sample within each stratum, as not every subject was on a condition-specific medication.
Within-subjects and between-subjects analyses gave the same results.
Within-subject variables are session (every third from 13 through 25) and within-session segment.
MEHP concentrations showed large within-subject variability, whereas MEP showed less within-subject variability.
Five methods were used to determine virologic compartmentalization between every tissue pair within each subject [33], [34], [35], [36].
Mixed between-within subjects analysis of variance allows combining between-subjects and within-subjects variables in one analysis (Pallant, 2013).
