So what can you say about the positive and negative reinforcing that's going on? Has the class been talking about operant conditioning? Skinner?
ADDED***
Screaming!
Timmy doesn't want to eat carrots but his parents keep trying to get him to eat them. At dinner time, if there are any carrots on his plate he will scream and shout until they are taken off his plate. His parents always give in to the tantrums and take away the carrots because his tantrums are becoming increasingly severe and last longer.
Why is this negative reinforcement?The carrots were present before Timmy had a tantrum. His tantrum then caused his parents to remove the carrots. Timmy's tantrums are getting more severe and lasting longer which suggests this behaviour is increasing, therefore the tantrums are being negatively reinforced by the removal of the carrots.
- Before: carrots on the plate.
- Behaviour: screaming.
- After: carrots no longer on the plate.
- Future behaviour: Timmy will scream when he doesn't want carrots.
