(2027 Exams) Psychological Explanations: Studies

Herman and Mack (1975)

Herman and Mack (1975) investigated disinhibition in restrained eaters (dieters). The study supports restraint theory as a psychological explanation for obesity.

Procedure

Laboratory experiment.
Two groups of participants who were either restricted eaters (dieters), or non-restricted eaters, were invited to take part in a study they were told was to test the impact of milkshake on perception of ice-cream flavours.
Participants were given either zero, one or two strawberry milkshakes (pre-load) and then 3 flavours of ice cream to taste. They could eat as much as they wanted.

Results & conclusions

Results
- The restrained eaters who had pre-loaded with milkshakes ate much more ice cream than the non-restrained dieters. It seemed once they had violated their diets they gave up on any self-restraint.
Conclusion
- The finding that restrained eaters eat more after violating a diet is termed the disinhibition effect.
