Aggregated Data Export
Export statistical metrics (dwell time, fixation counts, durations) in long format CSV for analysis in R, Python, or SPSS.
Purpose
Aggregated data export provides:
- Statistical metrics for each participant-stimulus-AOI combination
- Long format CSV structure optimized for statistical analysis
- Multiple metrics in a single export
- Compatibility with data analysis software
Export Configuration
File Settings
- File name - specify output CSV filename (without extension)
- Participant Group - select which participant group to include in export
Stimulus Selection
Choose one or multiple stimuli to include:
- Select from available stimuli using checkboxes
- Multiple stimuli will be combined in single CSV
- Each stimulus contributes separate rows to the dataset
Metrics Selection
Choose from following eye-tracking metrics:
Absolute Dwell Time
Total time spent in each AOI (ms) across all fixations.
Relative Dwell Time (%)
Dwell time as percentage of total viewing time for each AOI.
Time to First Fixation
Time until first fixation on each AOI (from stimulus start). Returns -1 if AOI was never fixated.
First Fixation Duration
Duration of the first fixation on each AOI. Returns -1 if AOI was never fixated.
Fixation Count
Number of fixations on each AOI.
Mean Fixation Duration
Average duration of fixations on each AOI. Returns -1 if AOI was never fixated.
Visit Count
Number of distinct visits to each AOI (consecutive fixations count as one visit).
Mean Visit Duration
Average duration of visits to each AOI. Returns -1 if AOI was never visited.
CSV Format
Structure
Long format CSV with columns:
- Participant_ID - numeric participant identifier
- Participant_Name - displayed participant name
- Stimulus - stimulus name
- AOI_Group - AOI name or special group
- Metric - metric type (e.g., "Dwell_Time")
- Value - calculated metric value
Special AOI Groups
- No_AOI - fixations outside any defined AOI
- Any_Fixation - aggregated values across all fixations
Example Data
Participant_ID,Participant_Name,Stimulus,AOI_Group,Metric,Value
1,"P01","Image1","Logo","Dwell_Time",1250.5
1,"P01","Image1","Logo","Fixation_Count",3
1,"P01","Image1","No_AOI","Dwell_Time",450.2Export Process
- Configure export settings (filename, group)
- Select stimuli to include
- Choose metrics to calculate
- Click Export CSV to download file
- Success message shows exported data points count
Statistical Analysis Usage
This format is optimized for:
- R - use
read.csv()and reshape/analyze with tidyverse - Python - import with pandas for statistical modeling
- SPSS - direct import for ANOVA and regression analysis
- Custom scripts - standard CSV format for any analysis tool
Analysis Tip
The long format structure makes it easy to perform grouped analyses, create visualizations, and run mixed-effects models with participant and stimulus as factors.
