A Task for Assessing the Impact of a Partner on the Speed and Accuracy of Motor Performance in Rats

DOI: 10.3791/60176-v
What you'll learn
  • ✓ Assemble apparatus for measuring rat motor performance in social contexts
  • ✓ Train rats on lever-pull and run-and-pull sequence tasks
  • ✓ Measure speed and accuracy of motor performance with and without social presence
  • ✓ Analyze behavioral data to quantify social facilitation/inhibition effects
Protocol

A procedure to measure the speed and accuracy of rats’ motor performance in a social condition is described. The protocol enables us to investigate the effect of the mere presence of others on speed and accuracy of motor performance in one experiment.

Difficulty
advanced
Total time
~4–6 weeks (including training phases and test sessions)
Model organism
Rat

Steps

1
Assemble operant apparatus and testing chamber

Construct the apparatus with lever, timing mechanisms, and social observation setup. Ensure proper configuration for measuring both lever-pull latency and accuracy.

2
Train rats on isolated lever-pull action

Shape lever-pulling behavior in individual rats through operant conditioning. Establish baseline speed and accuracy of the single motor action.

▶ 01:39
3
Train rats on run-and-pull sequence task

Teach rats to run from start zone and pull lever in sequence. Build proficiency in the combined motor task before testing social effects.

4
Conduct test phases with and without partner

Run performance trials under isolated (control) and social (partner present) conditions. Record speed and accuracy metrics for each trial.

▶ 02:56
5
Analyze speed and accuracy performance data

Extract latency and error rates from test trials. Compare metrics between solo and partner-present conditions using appropriate statistical methods.

▶ 03:31
6
Interpret training phase learning curves

Examine representative learning trajectories during lever-pull and run-and-pull training phases. Assess individual variation in acquisition rates.
