title: The relationship between top-down attentional control and changes in weight.
abstract: OBJECTIVE
  To investigate the relationship between top-down attentional control in the presence of food cues and weight change over a 3-month period.
  
  
  METHODS
  A Stroop task adapted to include background images of high-fat food and neutral items was completed by participants (N=60). Top-down attentional control was assessed by adaptation effects (Stroop effect is smaller when the previous trial is incongruent). To assess weight change, measurements were taken immediately after the Stroop task (T1) and again 3-months later (T2). Differences in weight between T1 and T2 were calculated and three groups formed: weight gain (n=20); weight loss (n=20); and no change in weight (n=20).
  
  
  RESULTS
  Differences in top-down attentional control were observed according to weight change. Participants who demonstrated reduced top-down attentional control also exhibited changes in weight (both loss and gain) over the 3-months. In contrast, the weight of participants who maintained top-down attentional control in the Stroop task remained stable.
  
  
  CONCLUSIONS
  Findings suggest that attentional control may have a role to play in actual eating behavior. Individuals who demonstrated reduced levels across of top-down attentional control also experienced changes in their weight over the 3-month period. Whether individuals lost or gained weight attentional control was reduced. This reduction was, however, not specific to high-fat food cues, but a general reduction in attentional control across both image conditions.
