Transparency repository for my doctoral dissertation entitled "Does varying cue-stimulus interval affect the sensory discrimination performance in the antisaccade task?"
Here you can find everything to reproduce the experiments I performed, i.e. the codes of the experimental procedures, raw and processed data, notebooks with analyzes and the final manuscript.
This project is supervised by Professor Adam Chuderski.
Whether the stimulus discrimination performance increases (e.g., due to goal strengthening), decreases (e.g., due to vigilance decay), or varies periodically (e.g., along attentional rhythms) as a function of time elapsing between task onset (fixation point, cue) and stimulus (cue-stimulus interval; CSI) is debated in the current literature on attention, and so far the findings have not been unequivocal. The aim of the project is to study the dynamics of the stimulus discrimination performance in the antisaccade task.
Research Question: Does varying cue-stimulus interval affect the sensory
discrimination performance in the antisaccade task?
Task: Antisaccade task. Description here and Repository here.
Task specification: 1a here and 1b here
Data A: 150 participants, CSI range 216-1000 wth 16.(6) ms step Available here
Data B: 40 participants, CSI range 400-900ms in 8.(3) ms step. Available here
⚠️ Due to COVID-19 related lockdown study was interrupted after 9 participants. That's why data are splitted into two Cohorts. Both cohorts did exactly the same procedure. Cohort 1 had 4 sessions containing 6700 trials, Cohort_2 had 2 sessions containing 4000 trials.
Data Issues: described here.
Question: Does stimulus discrimination performance oscillate?
Description: xxxxxxxxxxxxxxxxxx. Details here
DataSet: Data A
Notebook: Here
Result: xxxxxxxxxxxxx
Question: Does stimulus discrimination performance has a trend?
Description: xxxxxxxxxxxxxxxxxx. Details here
Notebook: Here
Result: xxxxxxxxxxxxx
No effect of CSI on stimulus discriminaton accuracy up to 1 sec.
Research Question: Does increasing or decreasing trend (or very slow oscillations)
in the sensory discrimination performance occurs in a broader CSI range?
Task: Same as in Experiment 1
Task specification: here
Data: Up to 300, during study Y
Research question: Why the commonly reported behavioral oscillations did not show up in our results?
Research Question: If not attention fluctuations determine performance in visual
discrimination tasks, then what? Rouder, 2022 replication.
Tasks: Anti and prosaccade (details here), inspection time (details here),
temporal order judgement appear/disappear (details here)
Tasks specifications:
Data: 50 participants
