The inhibition of oculomotor networks that delays prosaccade execution is not modulated by an increase in the number of previously completed antisaccades
Bibliographic record
Abstract
Our group has shown that prosaccades completed after antisaccades are associated with longer response latencies compared to the second of two consecutively completed prosaccades (i.e., so-called task-switch cost). This finding has been attributed to persistent residual inhibition of ocuolmotor networks arising from the response suppression and vector inversion required for the completion of an antisaccade (Weiler and Heath, 2011: Exp Brain Res). Here we sought to determine if a systematic increase in the number of previously completed antisaccades increase the prosaccade switch-cost. More specifically, we asked whether the residual inhibition from antisaccade completion compounds, and thus, further disrupts oculomotor networks supporting prosaccades. To accomplish our objective, 20 participants completed separate blocks of pro- and antisaccades, and two additional task-switching schedules wherein the nature of the saccade task (i.e., pro- or antisaccade) alternated on every second (i.e., AABB) or on every fourth (i.e., AAAABBBB) trial. Our results demonstrated that reaction times for prosaccades completed after antisaccades were longer than their task-repetition counterparts, and most notably, this switch-cost was equivalent across task-switching schedules. In addition, reaction times for prosaccade task-switch trials were longer than their blocked trial counterparts, whereas reaction times were not modulated across the different antisaccade conditions (i.e., switch, repeat and blocked). Thus, results demonstrate that the residual inhibition associated with antisaccade task completion is not compounded over successive antisaccade trials. Furthermore, we provide convergent evidence that the task-switch cost influencing the dedicated oculomotor networks supporting prosaccades does not modulate the performance of cognitively mediated antisaccades.Acknowledgments: NSERC, OGS

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
