• What is the focus of Behaviour Analysis?

  Behaviour Analysis focuses on quantifying cause and effect relations between behaviour and the environment

• Operant Conditioning - 3 term contingency

  1. Antecedent stimuli/events
  2. Behaviour
  3. The consequence of that behaviour

• When do discriminatory stimuli gain strength?

  When a behaviour has lead to a given consequence, whether stimuli was present or absent.

• What does the impact of a consequence depend on?

  The impact of a consequence depends upon the characteristic of the consequence. E.g. + or -
  
  Is this consequence going to lead to a + or - of behaviour in the future?

• What defines consequence or behaviour? Whether it is + or -?

  It is the effect of the consequence/behaviour that defines/determines whether it is a reinforcer or punisher.

• Example of classifying by effect/function

  If it does not increase behaviour (effect), it is not positive.

• Pavlovian conditioning is used to describe ___?

  It is used to describe the learning of stimulus-stimulus relations, as
  
  well as conditions that produce associations between stimuli, and the
  
  behaviour that these types of relations evoke.

• What is Acquisition and when does it occur?

  • Acquisition is the 'learning' of a behaviour, where the association is been acquired. (between stimuli and behaviour)
    
  • Most change in behaviour (signifies learning - acquisition), occurs in the early trials.
  • With subsequent trials, learning decreases (as it has reached asymptote)

• What can the Stimulus Intensity influence?

  The Stimulus Intensity can influence this acquisition phase (the rate of it).
  
  For example, the strength of the Unconditioned Stimulus (US), has influence on both the rate of of acquisition (learning, rate to asymptote) and the asymptote itself.
  
  E.g. A weak puff of air (US) paired with tone, would only produce CR - some of the time.
  
  Where as, a stronger puff of air (US),  affects the acquisition - faster, and stronger conditioning as indicated by the asymptote.

• Which two aspects of Learning is the strength of the US going to influence?

  1. How fast the association is acquired
     
  2. How strong the response will be
