Abstract:

Inhibitory control is a core function that allows us to resist interference from our surroundings and to stop an ongoing action. To date, it is not clear whether inhibitory control is a single process or whether it is composed of different processes. Further, whether these processes are separate or clustered in childhood is under debate. In this study, we investigated the existence and development of two hypothesized component processes of inhibitory control±interference suppression and response inhibition±using a single task and event related potential components. Twenty 8-year-old children and seventeen adults performed a spatially cued Go/Nogo task while their brain activity was recorded using electroencephalography. Mean N2 amplitudes confirmed the expected pattern for response inhibition with both the children and the adults showing more negative N2 for Nogo vs. Go trials. The interference suppression N2 effect was only present in adults and appeared as a more negative N2 in response to Go trials with a congruent cue than Go trials with an incongruent cue. Contrary to previous findings, there was no evidence that the interference suppression N2 effect was later occurring than the response inhibition N2 effect. Overall, response inhibition was present in both the children and the adults whereas interference suppression was only present in the adults. These results provide evidence of distinct maturational processes for both component processes of inhibitory control, with interference suppression probably continuing to develop into late childhood.

Abstract:

Traditional cognitive models of binge-eating behaviour in bulimia nervosa (BN) have long emphasised the importance of weight/shape concern and calorific restriction. However, the traditional cognitive framework continues to neglect the role of negative emotions, despite a growing body of alternative contemporary research suggesting binge-eating behaviour may develop as a mechanism for dealing with stress and negative emotionality. The current study investigated the unique contributions of emotional experience and emotion dysregulation to binge-eating behaviour in females with varying self-reported eating disorder (ED) characteristics. 79 females completed questionnaires measuring ED characteristics (EDE-Q), emotional experience (AIM and TAS-20), and emotion regulation difficulties (DERS and ERQ). 36 participants (11 meeting clinical criteria for BN and 5 for BED) had binged at least once in the past 28 days and 43 (none of whom met clinical ED criteria) had not binged. Results showed that those who binged at least once in the past 28 days (regardless of BN) had more difficulties identifying and describing their feelings, experienced emotions with higher intensity and had more difficulties regulating their emotions than females who had not binged. Deficits in emotional introspection, description and regulation predicted binge-eating behaviour. Overall, whilst a traditional framework (weight/shape concern and calorific restriction) did explain some of the variance in binge-eating behaviour in the current sample, the model significantly improved once emotional regulation was added. These results suggest emotionality should not be neglected as a predictor of binge-eating, with important implications for treatment in disorders like BN.
