Why participants in a negative mood would show increased salivation in response to the CS− is unclear, especially considering the conditioned expectations to eat and the learned desire to eat that were both found in the negative mood condition. The inhibited salivary response to the CS− in the neutral mood condition would indicate that they have learned that the CS− would not be followed by food intake. The negative mood condition, on the other hand, did not show evidence of inhibited salivation to the CS−. In anticipation of more research on this topic, it could be that a negative mood generally leads to increased salivation, and that this general response is stronger than a conditioned inhibitory response. The few existing findings on mood states influencing salivation are mixed. Bulik, Lawson, and Carter (1996) reported a negative association between depression levels and salivation, while studies on the relationship between anxiety or stress and salivation have shown an increase or no salivary changes .With our negative mood manipulation we cannot be sure exactly what kind of negative emotions we tapped into and how this might have influenced salivary responding
