Protocol

Poisson clicks evidence accumulation task

Subjects accumulate temporally distributed auditory click evidence and choose the side associated with the greater click count or rate over the stimulus period.

Task structure

Stimulus, choice, feedback, and training as declared in the protocol record.

Stimulus

evidence_schedule
Left and right click trains are generated over time, commonly with stochastic timing; accumulated evidence is the relative count or rate across sides.
evidence_type
pulse-train
modalities
auditory
notes

units
clicks, clicks per second
variables
left click count, right click count, click count difference, click rate, stimulus duration

Choice

action_mapping
Subjects choose the side with more clicks, using species- and apparatus- specific response actions.

Feedback

feedback_type

notes
—
penalty
Error feedback or timeout depending on implementation.
reward
Reward for correct side choices in animal implementations.

Training

notes
Human and rat implementations require separate implementation records.

task shaping, accumulation training

Trial timing

  1. trial_initiation
    protocol-specific

    Subject initiates the trial.

  2. click_train
    protocol-specific

    Auditory evidence unfolds over time.

  3. response
    protocol-specific

    Subject reports the side with greater accumulated evidence.

  4. feedback
    outcome-dependent

Expected analyses

  • psychometric curve by click count difference
  • chronometric curve by evidence strength
  • evidence-kernel or reverse-correlation analysis
  • accumulation model fit

Interpretive claims

  • evidence accumulation
    Confidence: high · ref.brunton-2013-clicks

Open questions

  • Separate rat and human implementations after deeper source curation.
  • Add exact click-generation parameters from the original study.
