Mahmoud wants his seven-year-old daughter to learn that littering is bad. according to cognitive dissonance theory, how should mahmoud teach his daughter not to be a litterbug? mahmoud should give his daughter a big ice cream cone every time she throws her garbage in a trash can. yell and scream at his daughter every time she tosses garbage on the ground. give his daughter a stern look whenever she litters. raise his daughter's allowance whenever she refrains from littering.

This  theory suggests that we have an inner drive to hold all our attitudes and behavior in harmony and avoid disharmony (or dissonance). This is known as the principle of cognitive consistency.

When there is an inconsistency between attitudes or behaviors (dissonance), in this case littering something must change to eliminate the dissonance.

Mum should reward her daughter, everytime whe refrains from littering, and in this way, she should eliminate the dissonance. An appopiate response would be to raise his daughter's allowance whenever she refrains from littering.
