Examples of Delayed Reinforcer vs Immediate Reinforcers

We may be inclined to engage in small immediate reinforcers(watching TV) rather than large delayed reinforcers (getting an A in a course)which require consistent study.

Continuous Reinforcement

Reinforces the desired response each time it occurs

PartialReinforcement

Reinforces a response only part of the time. Thoughthis results in slower acquisition inthe beginning, it shows greater resistance to extinction later on.

The _____ or _____, comeswith a bar or key that an animal manipulates to obtain a reinforcer like foodor water. The bar or key is connected to devices that record the animal�sresponse.

Shaping

Continuous Reinforcement

Reinforces the desired response each time it occurs.

Partial Reinforcement

Reinforces a response only part of the time. Though this results in slower acquisition in the beginning, it shows greater resistance to extinction later on.

Fixed-ratio schedule:

Reinforcesa response only after a specified number of responses. e.g., piecework pay.After reward, brief pause, then returns to high rate

Variable-ratio schedule

Reinforces a response after an unpredictable number of responses. This is hard to extinguish because of the unpredictability. (e.g., behaviors like gambling,fishing.)

Fixed-interval schedule

Reinforces a response only after a specified time has elapsed Increases responses as the anticipated time draws near (e.g., checking mail)

Variable-interval schedule

Reinforces a response at unpredictable time intervals, which produces slow, steady responses. Slow, steady responding (never know when�)

Punishment

An aversive event that decreases the behavior it follows.?

1.Results in unwanted fears.

2.Conveys no information to the organism.3.Justifies pain to others.4.Causes unwanted behaviors to reappear in its absence.5.Causes aggression towards the agent.6.Causes one unwanted behavior to appear in place of another.

Rats seem to develop ______ or mental representations, of the layout of the maze (environment).

cognitive maps,

Such cognitive maps are based on ___ ___ which becomes apparent when an incentive is given

latent learning,

Intrinsic Motivation

The desire to perform a behavior for its own sake.

Extrinsic Motivation

The desire to perform a behavior due to promised rewards or threats of punishments.

Unnecessary rewards can harm intrinsic motivation, Example... E.g.,children promised a reward for playing with an interesting toy later play with the toy less than unpaid counterparts

E.g.,children promised a reward for playing with an interesting toy later play with the toy less than unpaid counterparts

It is eaiser for an orginism to learn to operate associations that are ___ or ____

Ecologically relevant, or Evolutionarily adaptive

Ecologically relevant

similar to how stimuli are associated in the natural environmentE.g., teaching a pigeon to flap its wings to avoid shock

reinforcing good behavior increases the occurrence of these behaviors. Ignoring unwanted Behavior (whining) ...

decreases their occurrence.

Modeling

Higher animals, especially humans, learn through observing and imitating others.

Neuroscientists discovered ____ ____ in the brains of animals and humans that are active during observational learning.It also Helps withempathy and theory of mind.
