Document Summary
Sometimes behaviour changes dramatically in a brief span of time, but most of the time behavioural changes are small and subtle: most shaping involves small and subtle forms of behaviour modification. Increased knowledge about shaping helps us gain increased power to guide shaping processes. Five ways of learning often intertwine in various combinations in everyday life. Differential reinforcement: whenever people"s behaviour is variable and some of these variations lead to reinforcement, but others do not, the behaviour is under differential reinforcement, reinforced variations become more frequent while non-reinforced or punished variations become less frequent. As he plays with the three behaviours, the consequences that follow each behaviour begin to modify its frequency via differential reinforcement. If b1 leads to food falling on the floor, the child receives no reinforcement and the behaviour begins to extinguish. If b2 results in food on the chair, there is no reinforcement and b2 is extinguished.
