Contemporary Western environments are saturated with palatable food cues. People are continually exposed to images that are associated with food intake, such as advertisements on bill-boards and television, vending machines and fast food outlets. The mere presence of such food cues has been linked to increased food intake (Fedoroff et al., 1997, Fedoroff et al., 2003 and Painter et al., 2002) and is an acknowledged contributor to the increased prevalence of overeating and obesity (Westerterp & Speakman, 2008).
