Answer: conditional positive regard
Explanation: Conditional Positive regard refers to an act whereby an individual receives warmth, acceptance etc when some certain standards and conditions are met. For example, a parent praises a child when they receive good grades in their exams and scold vehemently when they get bad grades.
