The role of rule-governance in producing verbal behaviour associated with dissociative identity disorder (DID) was investigated, using a single-factor, between-subjects design. Fifty-two undergraduates role-played the part of an accused murderer undergoing a psychiatric assessment to prepare a legal defense. Participants were assigned randomly to one of three groups, a DID rule group, a self-defense rule group, or a control group. Participants then underwent a mock psychiatric assessment. Specific verbal behaviour of participants during the assessment was analyzed between groups. The hypothesis that individuals in the DID group would demonstrate more verbal behaviour associated with DID than those in either of the other groups was supported by data from a structured interview and a self-report measure; however, a statistically significant difference among groups was observed on only one (initial denial) of six dimensions on an unstructured interview. This latter result suggests that the contextual cues and perceived situational demands associated with the mock psychiatric interview were powerful enough to overcome the effect of the differential instructions. / February 2008

The large number of scalar meson states below 2 GeV contradicts the expected number derived from a quark-antiquark description. One possibility is that one or more of the light scalar mesons can be described as four quark states composed of quark-antiquark pairs. This scenario has been explored with sum-rule methods in Quantum Chromodynamics (QCD) to leading-order in the strong coupling constant. Higher loop contributions are significant in the QCD sum-rule analysis of quark-antiquark scalar states and a similar situation could occur in the four-quark case. In this thesis the leading order and pieces of the second order terms of the correlation function, as needed to study properties of a four-quark state via a QCD sum-rule, is calculated in the chiral limit (i.e. massless quarks) in QCD. Operator mixing related to renormalization of the composite operators appearing in the correlation function first contributes at second order. The result for the second order contributions to the correlation function indicate that operator mixing must be addressed before using proper dispersion relations to link this calculation with the mass of an existing state.
