The 20 questions

  1. According to restraint theory, attempting to strictly restrict food intake often leads to what outcome?

    • Overeating
    • Constant satiety
    • Anhedonia
    • Weight loss

  2. What term describes the loss of restraint over eating in response to external cues or stress?

    • Sensitisation
    • Restraint
    • Habituation
    • Disinhibition

  3. Twin studies suggest obesity has a strong genetic component, meaning it is mostly what?

    • Recessive
    • Monogenic
    • Sex-linked
    • Polygenic

  4. Which neurotransmitter is primarily linked to the reward circuitry in neural explanations of obesity?

    • GABA
    • Serotonin
    • Dopamine
    • Acetylcholine

  5. Eating heavily after a stressful event despite previously dieting strictly is an example of what process?

    • Social learning
    • Disinhibition
    • Restraint
    • Desensitisation

  6. According to Herman and Polivy's boundary model, dieters set which boundary to control their eating?

    • Hunger boundary
    • Satiety boundary
    • Physiological boundary
    • Dietary boundary

  7. In Herman and Mack's milkshake study, what did restrained eaters do after consuming a high-calorie preload?

    • Showed no change
    • Ate less food
    • Ate more food
    • Stopped eating completely

  8. Genetic explanations of obesity are limited because genetics interacts heavily with which factors?

    • Cognitive distortions
    • Environmental factors
    • Unconscious conflicts
    • Peer pressures

  9. Brain imaging studies supporting neural explanations of obesity often show altered activity in which pathway?

    • Motor pathway
    • Visual pathway
    • Reward pathway
    • Auditory pathway

  10. What term describes eating triggered by the sight or smell of food rather than internal hunger?

    • Restrained eating
    • External eating
    • Emotional eating
    • Boundary eating

  11. Thinking 'my diet is ruined, so I may as well keep eating' illustrates which effect?

    • Abstinence violation effect
    • Hawthorne effect
    • Framing effect
    • Placebo effect

  12. Why is it difficult to prove that restraint causes overeating in psychological obesity research?

    • Results lack validity
    • Samples are non-human
    • Data is qualitative
    • Evidence is correlational

  13. Which model best combines genetic predispositions and psychological triggers to explain obesity?

    • Psychodynamic model
    • Biological model
    • Behavioural model
    • Diathesis-stress model

  14. What term describes overeating triggered by breaking self-imposed dietary rules?

    • Restraint
    • Disinhibition
    • Boundary model
    • Satiety deficit

  15. Which neurotransmitter pathway is most associated with reward in neural explanations of obesity?

    • Serotonin pathway
    • Sympathomedullary pathway
    • HPA axis
    • Mesolimbic dopamine pathway

  16. Which factor best explains why recent rapid increases in obesity rates cannot be purely genetic?

    • Gene mutations
    • Inherited satiety levels
    • Evolutionary adaptations
    • Environmental changes

  17. What effect does increased dopamine activity in reward pathways have on eating behaviour?

    • Loss of taste
    • Complete satiety
    • Reduced food intake
    • Increased food intake

  18. According to restraint theory, what directly triggers disinhibition in restrained eaters?

    • Weight loss
    • High serotonin levels
    • Continuous starvation
    • Perceived overeating

  19. What is a major limitation of restraint theory as an explanation for obesity?

    • Partial explanation
    • Only affects males
    • Completely invalid
    • Purely genetic model

  20. A genetic variant causing reduced satiety signalling supports which type of explanation for obesity?

    • Biological explanation
    • Behavioural explanation
    • Psychodynamic explanation
    • Social learning explanation
