Paradigm | Decade1) | Theory | Key concepts |
(Connectionism)2) | 1880 - 1900 | Connectionism (Thorndike) | - learning is incremental strengthening of the S-R3) association |
- S-R associations are strengthened through repetition |
- outcome of a S-R event can strengthen or weaken the connection |
- potential to learn leads to frustration if not satisfied |

Behaviorism | 1900 - 1910 | Classical conditioning (Pavlov) | - learning is a visible change in one's behavior |
- learning is manifested in a natural reflex reaction on an associated environmental stimulus |
- emotional response can also be learned or conditioned |
1920 - 1930 | Contiguity theory (Guthrie) | - behavior is formed by a series of movements which are learned through S-R associations |
- a close temporal relationship between S and R is necessary for learning to occur |
- learning occurs on first experienced instance of the stimulus |
- reinforcements (reward or punishment) do not influence the strength of this connection |
| | | |
Neo-behaviorism | 1930 - 1940 | Sign learning (Tolman) | - suggests studying behavior on the molar level (whole, purposeful, goal-directed behaviors) |
- learning is acquisition of knowledge through meaningful behavior, not mechanical moves |
- rewards or punishments can only be used as motivators for performance, not learning |
- animals are not simple mechanisms, but intelligent organisms capable of cognitive processes |
Drive reduction theory (Hull) | - mathematical formulas attempting to explain behavior and the likelihood of its appearance |
- drive (a stimulus in form of a biological need) results in behavior in order to satisfy it |
- reinforced S-R learning through the reduction of a biological drive |
- cognitive factors need to be taken into account when explaining human learning |
1950 - 1960 | Operant conditioning (Skinner) | - reinforced learning of new behaviors, not just shaping reflexes |
- different reinforcement intervals have different effect |
- complex behaviors are learned through more simple ones |
Stimulus sampling theory (Estes) | - a statistical learning theory; set of formulas and axioms |
- S-R association is learned in a single trial; learning results in accumulated S-R associations |
- reinforcement has to do with the performance, not with learning |
- later included memory as a factor in his theory |
