+200 students received requests from their parents asking them to study more. These were formulated in a controlling, neutral or autonomy-supportive way. 


When requests were made in a controlling way, adolescents expressed more frustration, pressure and reactance. Consequently, they acted in the opposite way and didn’t study. 


We are less likely to adopt a behavior if we feel coerced or threatened.
