Discrminative Stimulus...

[sandi]

What is the discriminative stimulus in this scenario?
Frank competes in high level athleitcs competitions. on the last two occasions that he won the race, he wore his lucky-gold chain.Frank now wears his gold chain everytime that he competes believing it to be his lucky chain.

I believe that the reinforcement (winning), of the stimulus (the gold chain), has lead Frank to believe that ONLY THAT SAME gold chain will lead to the same correct response (winning the next race).

I could be wrong.

Personally I would have put this, although I'm not 100% sure.
Discriminative Stimulus - competing in high level athletics competitions
Response - wearing the lucky-gold chain
Consequence - Winning the race; the effect on future behaviour is that he is positively reinforced and subsequently wears it every time.

That question was from the 2010 exam, back before there was a 'three-phase model' in the study design. So the marks are allocated to the behaviour, the consequence, and the effect of reinforcement. You could probably still find the discriminative stimulus just for practice though - I'd personally be inclined to say that it would be running the race or competing in athletics competitions.
