Figure 1

Schematic representation of possible functional relationships between inhibitory control and hallucination frequency. Solid black line (graphic file with name fnhum-08-00180-i0001.jpg) depicts a roughly linear association between inhibition difficulty and AH frequency. Solid gray line (graphic file with name fnhum-08-00180-i0002.jpg) indicates a potentially non-linear relationship between inhibition and AH frequency, characterized by a critical “tipping point” (dashed line) in inhibitory dysfunction, beyond which the frequency of hallucinations rises markedly. Right vertical axis illustrates the link with the degree of OFC activation, which influences the emotional valence of participants' response (details in text).
