Operant control of human eye movements

Area of Science:

• Neuroscience
• Behavioral Science
• Primate Studies

Background:

• Saccades and smooth pursuit are crucial for gaze shifting in primates.
• Understanding the control of these eye movements is key to understanding sensorimotor integration.

Purpose of the Study:

• To review evidence on how reinforcement affects saccade and smooth pursuit eye movements.
• To propose that these eye movements are operant behaviors influenced by task performance consequences.

Main Methods:

• Literature review of studies examining reinforcement effects on eye movement dimensions (latency, velocity, amplitude).
• Theoretical analysis proposing an operant conditioning framework for eye movements.

Main Results:

• Evidence suggests reinforcement modulates various dimensions of saccades and smooth pursuit.
• Eye movement parameters can be shaped by their consequences on task performance.

Conclusions:

• Saccades and smooth pursuit can be viewed as operant behaviors.
• Studying reinforcement effects offers insights into how motor responses adapt to environmental demands.
