Variability for individuals themselves in the sample.

Variability of specific scores for individuals in the sample.

A value on a regular grid in three-dimensional space. In this case, composes the 3-dimensional brain image.

3 Tesla-powered scanner model. In our replication, we will be using a different scanner.

A cross presented to research participants in a perception task with the intent directing the participants' attention to wherever the investigator wants them to look.

The amount of time between the end of one stimulus being presented and the start of another stimulus being presented.

MR imaging frequency that displays gray matter as the brightest contrast, white matter as the second brightest contrast, and CSF matter as the third brightest contrast.
