• Sex is a non-homeostatic drive | It is independent of bodily need states or physical deprivation cycles |
Yerkes-Dodson Law | • If a task is simple, it is best for arousal to be high; if it is complex, lower levels of arousal provide for the best performance |
• Arousal theory | Assumes people prefer to maintain ideal, or comfortable, levels of arousal |
• Sensation seeking | Trait of people who prefer high levels of stimulation |

• Need for affiliation | Motivation to be with others |
• Need for power | Desire to have social impact or control over others |
• Hierarchy of human needs | Maslow’s ordering of needs is based on some needs being more powerful than others and thus will influence a person’s behaviour to a greater degree |
• Basic needs | First four levels of needs in Maslow’s hierarchy |
• Intrinsic motivation | Motivation coming from within, not from external rewards; based on personal enjoyment of a task or activity |

• Polygraph | Device that records changes in heart rate, blood pressure, respiration, and galvanic skin response (GSR); known as a lie detector |
• Irrelevant questions | Neutral, non-threatening, non-emotional questions in a polygraph test |
• Relevant questions | Questions to which only someone guilty should react |
• Control questions | Questions that almost always provoke anxiety in a polygraph (e.g. “Have you ever taken any office supplies?”) |
James-Lange Theory of Emotion | • Experience of emotion is awareness of physiological responses to emotion-arousing stimuli |
Cannon-Bard Theory of Emotion | • Emotion-arousing stimuli simultaneously trigger • physiological responses • subjective experience of emotion |
Schachter’s Two Factor Theory of Emotion (Cognitive Theory) | • To experience emotion, one must • be physically aroused • cognitively label the arousal |
