Lastly, again little agreement was found between what participants believed to predict their consumption and SAM2s findings.įinally, in Chapter 5 the key theoretical and practical implications of this work are discussed, particularly in how the findings relate back to the grounded cognition theory and the wider literature. As in Chapter 3 and 4 large individual differences occur in predictive patterns as well as participants perception of the diverse food groups, although (again) automaticity emerges as most important across participants. In contrast, consumption motivations remain stable over time. Findings show the occurrence of learning effects for some of the predictors, meaning the association between consumption and the predictors increases overtime.
The empirical work presented in Chapter 4 expands on the findings in Chapter 3 by assessing consumption motivations of diverse food groups across a two-week timespan. Little agreement was found between what participants believed to influence their consumption and SAM2s predictive profiles, potentially indicating that participants have little insight into what predicts their consumption. Remarkably, findings indicate that individual’s predictive patterns remain stable across eating occasions. Lastly, Study 3’s results demonstrate (again) large individual differences across individual’s predictive patterns, again with the exception of automaticity which was important for both consumption frequency and desire across participants. Study 2 identifies the relevant underlying motives predicting consumption frequency and desire. Study 1 establishes an extensive sample of foods consumed in eight different eating situations in the UK. Lastly, participants differ greatly in their perception of the different beverages.Ĭhapter 3 presents the results of three separate studies with the overarching aim to establish individual’s predictive patterns for their consumption frequency and desire of situated foods and beverages and to assess the stability of those patterns across different eating occasions. In contrast, large individual differences occur across participants’ predictive patterns, although habit emerged consistently as important. Findings show that predictive patterns remain remarkably stable across individual beverages. This thesis’ objective is to add to the understanding of consumption motivations, by establishing diverse motives for food and beverage consumption, assessing their stability across eating occasion, time beverages and foods, and exploring intra- and individual differences, using a situated measuring approach.Ĭhapter 2 establishes a seven-factor framework predicting the consumption frequency of alcoholic and non-alcoholic beverages. Consequently, there is a gap in the literature of the underlying intra- and individual differences in food and beverage consumption motivation patterns and their stability across different domains. Previous research has typically used unsituated self-report measures at a single timepoint to identify and establish the importance of diverse consumption motives (e.g., habit, health, liking etc.) by averaging across participants, simply presuming relative stability across individuals, eating occasion and time. To achieve this goal, it is essential to first fully understand how eating and drinking, both highly complex, multifaceted behaviours, are influenced by internal and external factors. To tackle some of the most pressing challenges of our time, the obesity epidemic and climate change, novel interventions, regulations and public policies are needed to help people shift towards healthier and more sustainable diets.
