Task | Goal | Criteria | Adjustment |
|---|---|---|---|
Head-fixed | Increase punishment to correct for port bias. | Manual: >70% (hit + false alarm) | Manual: 2–10 s time out 1–10 air puffs |
Head-fixed | Decrease punishment to reduce disengagement | Manual: 20–50% miss | Manual: |
Home cage | Increase punishment to correct for port bias. | 50 trial sliding window <70% correct (d’ ~1.05) | Increase 1 s time out (10 s max) For >7 s time out, increase 1 air puff (5 max) |
Home cage | Decrease punishment to reduce disengagement | 50 trial sliding window >50% miss | Decrease 2 s time out and 2 air puffs |
Head-fixed | Adjust stimulus probability to correct for report biases | Manual: >70% (hit + false alarm) | Manual: Up to 0.35/0.65 (NM/M) |
Home cage | Adjust stimulus probability to correct for report biases | 20 trial sliding window X = % trials favored port Y = % trials neglected port Moderate bias: X–Y > 0.25 Severe bias: X–Y > 0.5 | X = stim. of favored port Y = stim. of neglected : 0.35/0.65 (X/Y) severe: 0.2/0.8 (X/Y) |
Both | Adjust stimulus probability to correct for primacy or recency stimulus bias | 20 trial sliding window For non-match stim: X = % correct fav. stim Y = % correct NM stim For match stim: X = % correct fav. stim Y = % correct M stim moderate: (X/Y-0.5) > 0.55 severe: (X/Y-0.5) > 0.6 | X = favored stim. Y = neglected stim. moderate: 0.4/0.6 (X/Y) severe: 0.3/0.7 (X/Y) |
