Social behaviour

• Behaviour that reacts to other behaviour
• Signal = The behaviour triggering a response

           - Student raises hand = signal
           - Teacher speaks to student = response 

• Signals humans: expression, posture, gestures, language
• Signals animals: colors, sounds, scents, expression, posture

Observing behaviour

• Looking at behaviour = observing
• Understanding behaviour = interpreting
• Studying behaviour

       - Making an ethogram = observing
