- Rational motives involve selecting goals based on objective criteria like price, while emotional motives rely on subjective personal criteria.
- Needs are never fully satisfied and new higher goals emerge as old needs are met, leading to frustration if goals cannot be achieved.
- Motives can be aroused physiologically, emotionally, cognitively, and environmentally. Behaviorist and cognitive schools view this arousal differently.
- Models like Maslow's hierarchy and Murray's needs attempt to categorize the different types of human needs and motivations.
