For instance, relaxation does not seem to account for the reduction of pain in Highs (Castel, Perez, Sala, Padrol and Rull, 2007;Appel and Bleiberg, 2005), while the role of expectation has not been defi nitely assessed because some fi ndings indicate it to be a mediator of the effectiveness of hypnotic treatments (Milling et al, 2006;Milling, Shores, Coursen, Menario and Farris, 2007) and others discount its contribution (Castel et al, 2006). Suggestibility could be enhanced by situational variables, i.e.…”
