Mechanisms of emotional eating: Food approach bias covaries with affect on days with high food craving
Emotional eating (EE) - eating in response to emotions - has clinical relevance, yet its underlying mechanisms (how?) remain poorly understood. Questions also concern interindividual differences (who?), and the types of foods involved (what?). We hypothesized that negative affect would be linked to increased, and positive affect to decreased food approach bias (how?). These effects were expected to be moderated by trait EE (who?) and by the goal-…
Reaction-time task reliability is more accurately computed with permutation-based split-half correlations than with Cronbach’s alpha
While it has become standard practice to report the reliability of self-report scales, it remains uncommon to do the same for experimental paradigms. To facilitate this practice, we review old and new ways to compute reliability in reaction-time tasks, and we compare their accuracy using a simulation study. Highly inaccurate and negatively biased reliability estimates are obtained through the common practice of averaging sets of trials and submit…
Retracted: The only constant is change: Stable vs. variable aspects of food approach bias relate differently to food craving and intake
The tendency to approach food faster than to avoid it (i.e., approach bias) is thought to facilitate food intake, particularly foods that conflict with one's dietary goals. However, this relationship has been difficult to demonstrate, which ties into an ongoing debate about whether such cognitive-behavioral biases represent stable traits or fluctuating states. We thus investigated the temporal fluctuations of food approach bias (1), its within-pa…
The dual-feature approach-avoidance task: Validity, Training Efficacy, and the Role of Contingency Awareness in Changing Food Preference
rate of approaching fruit versus chocolate correlated with many outcome measures, suggesting contingency awareness plays a major role in AAT training effectiveness, challenging implicit accounts. While the dual-feature paradigm shows potential, its high error rates, RTs, and difficulty mandate improvement
Touchscreen-based measurement of food approach-avoidance bias: Seeking a reliable and valid paradigm
Working towards a reliable and valid touchscreen-based food approach avoidance task: A mini-review
Touchscreen-based assessment of food approach biases: Investigating reliability and item-specific preferences
Strong cravings for unhealthy foods and implicit tendencies to approach them threaten the physical and mental health of vulnerable populations. Yet, implicit measures of food approach tendencies have methodological limitations, as existing approach-avoidance tasks (AAT) are often unreliable and require specialized hardware. We propose a novel method to measure approach biases: on a touchscreen, participants slide their hand either toward a food i…
Comparison of different response devices to assess behavioral tendencies towards chocolate in the approach-avoidance task
Food approach bias is moderated by the desire to eat specific foods
In a post-scarcity world, energy intake and excesses therein are mediated by psychological mechanisms, such as implicit inclinations to approach certain foods. We investigated how food deprivation, calorie content and individual food preferences affect this approach bias. Sixty women performed a touchscreen-based approach-avoidance task featuring a wide range of food items, once while satiated and once while food-deprived for 15 h. We found an ov…
