    Study Notes

    Motivation

    • Motives are needs, wants, interests, and desires that propel people in certain directions
    • Motivation involves goal-directed behavior

    Theoretical Approaches

    • Drive Theories: a hypothetical, internal state of tension that motivates an organism to engage in activities that should reduce this tension
    • Incentive Theories: external stimuli regulate motivational states, pulling people in a particular direction

    The Range of Motives

    • Biological Motives:
      • Survival
      • Hunger
      • Thirst
      • Sex
      • Sleep
    • Social Motives:
      • Affiliation
      • Achievement
      • Nurturance
      • Exhibition

    The Motivation of Hunger and Eating

    • Biological Factors:
      • Hypothalamus: regulates hunger, but not an on/off switch
      • Glucose regulation: insulin plays a role in determining hunger
      • Digestive regulation: ghrelin and CCK hormones regulate hunger and satiety
      • Hormone regulation: leptin informs the hypothalamus about the body's fat stores
    • Environmental Factors:
      • Incentive value of food: availability, palatability, variety, presence of others
      • Environmental cues: adverts
      • Learned Preferences and habits: classical conditioning and observational learning

    Sexual Motivation and Behaviour

    • The Sex Drive: ensures the survival of the species
    • The Biological Response:
      • Human Sexual Response Cycle:
        • Excitement Phase: physical arousal, vasocongestion
        • Plateau Phase: physiological arousal builds
        • Orgasmic Phase: peak of intensity
        • Resolution Phase: physiological changes subside
    • Parental Investment: effects interest in sexual activity, promotes selective mating
    • Sexual Orientations:
      • Kinsey's 7-point scale
      • Biology: hormonal secretion in critical periods of prenatal development

    Achievement Motivation

    • The need to master difficult challenges, outperform others, and meet high standards of excellence
    • Correlates positively with success
    • Factors influencing achievement motivation:
      • Strength of motivation to achieve success
      • Estimate of the probability of success
      • Incentive value of success

    Emotional Experience

    • Emotion involves:
      • Subjective conscious experience (cognitive component)
      • Bodily arousal (physiological component)
      • Characteristic overt expressions (behavioral component)

    The Cognitive Component

    • Highly personal and subjective experience
    • Cognitive appraisals of events determine emotion
    • Evaluative aspect: can be automatic/unconscious
    • Poor affective forecasting: efforts to predict one's emotional reactions to future events

    The Physiological Component

    • Autonomic arousal: autonomic nervous system responsible for physical arousal
    • Neural circuits: amygdala, hypothalamus, and structures in the limbic system
    • Thalamic-amygdala-hypothalamic pathway: sensory information triggers autonomic arousal and hormonal responses

    The Behavioral Component

    • Emotions expressed in nonverbal behavior: body language
    • Paul Ekman's facial cues: 6 fundamental emotions (happiness, sadness, anger, fear, surprise, and disgust)
    • When contracting facial muscles, may experience the corresponding emotion

    Theories of Emotion

    • James-Lange Theory: conscious experience of emotion results from perception of autonomic arousal
    • Cannon-Bard Theory: emotion occurs when the thalamus sends signals simultaneously to the cortex (conscious experience) and the autonomic (visceral arousal)
