Abstract:
Individuals differ in the extent to which they can detect internal bodily signals (interoceptive sensitivity). Recent research suggests that interoceptive sensitivity might influence responsiveness to signals associated with hunger and fullness and BMI (Herbert et al., 2013). The current research sought to expand on this finding and to explore how interoception may influence other aspects of ingestive behaviour. Five studies are described, which outline the role of interoception in relation to:  dietary learning (study 1), decisions made about portion size (study 2), whether the effects of consuming large meals on subsequent cognitive functioning are anticipated (study 4), and whether memory for recent eating and interoception have a combined effect on later intake and food-cue reactivity. Across these studies there was little evidence of individual differences in interoception affecting appetitive behaviour. It is not clear whether this is the consequence of the methods used or whether there is a theoretical issue with some of the assumptions made.  The presentation concludes by outlining possible avenues for future research but also questions whether this line of research should be pursued.
