Fixation probability data generated by ft2fp() function

Description

This data set is the fixation probability data generated by the ft2fp() function. The data set retains the information of list, subject, and condition of original fixation time data set. The variable "Time" is generated based on the TimeCourse and TimeInterval arguments defined by users. The variable "N" is the total number of valid trials after the deletion of invalid ones for the corresponding spatio-temporal unit. The variable "y" is the number of trials with fixations on that particular region at that time point. Fixation probability is calculated by dividing y by N. "N" and "y" would be used for further analysis in empirical logistic transformation and lme modeling.

Usage

Format

In the data frame each row represents the fixation probability and other information for one spatio-temporal unit. The data frame has the following columns:

list

the id of the list

subject

the id of the subject

condition

the id of the condition

region

the id of the region

Time

the time after eyes leave critical region

N

total number of valid trials

y

number of trials with fixations

fix_prob

the fixation probability
