Weber’s Law
- Change in a stimulus that will be just noticeable is a constant ratio of the original stimulus
- If 5 gram is the noticeable difference between 100 and 105 grams, then for 1000 gram, it will be 1050 gram
- Hence, Weber Fraction is 5/100
Introspection

Image of an object that comes to mind first
Tabula Rasa
We are born with an empty slate
Rationalism
Life should be based on logic, rather than emotions and religion
Body-Mind Problem
Monoism - only mind exists or only body exists

Behaviorism
- The behaviour of a person is the product of all one has learned in the past
- Behaviors are acquired through conditioning, and conditioning occurs through interaction with the environment
Classical Conditioning
- Something that produces a response becomes paired with something else
- Over time, the ‘something else’ produces the same response
- Thoughts and feelings were irrelevant-
See docs
Operant Conditioning
- Reward or punishment make a behaviour more or less likely
- Assumption: Behavioural Hedonism: We are motivted to learn to seek pleasure and avoid pain- Reward or punishment make a behaviour more or less likely
