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)
