Q

Properties of Habituation
A) who proposed?

1) Course
2) Time
3) Relearning
4) Stimulus intensity
5) overlearning
6) generalization

A

A) Thompson and Spencer

1) Course: an inverted curve of decreasing returns
2) Time: habituation dissipates with time, like forgetting
3) Relearning: repeated exposures produce more rapid habituation
4) Stimulus Intensity: Habituation is faster for weaker stimuli and may not occur at all to a very strong S
5) Overlearning: re-exposure to a stimulus following complete habituation produces decreased relearning time (T&S call this below-zero habituation).
6) Generalization: Habituation processes occur more quickly to new stimuli in proportion to their similarity to the original

These characteristics (except stimulus intensity) are similar to learning phenomena.

39
Q

[Costs and Benefits of Learning]

Benefits

A

Examples are birds learning to recognize eggs or avoid rearing parasites (cuckoo) or young of other parents. Such learning is more successful than an instinct and more likely to develop and be successful when:
 There is time and opportunity to learn
 Stimuli involved are variable and unpredictable (learned to avoid that food, etc.)
 Information so affects fitness it is worth the neuronal development

40
Q

[Costs and Benefits of Learning]

Costs

A

Neurons needed for storage, reward and punishment systems, and modification of behavior. The brain has major biological costs: it is 2% of body weight, uses 15% of heart output, 20% of oxygen, 25% of body energy (13% in other primates, 2-8% in most vertebrates).

  • Need bigger heart, bigger lungs, more food to keep things going. Has to be a big payoff to offset the biologically significant cost.
  • Learning can produce errors in avoiding good food after a poor experience or produce results (birth control) that are biologically inappropriate.
  • Deception may provide faulty information to be learned.
41
