Perspective-taking is a new topic in the field of behavior analysis and has become of extreme interest. Previous research has looked at perspective-taking using a protocol that has been previously developed. Research in this field has looked at whether the lack of perspective-taking (mindblindness) is the cause for social deficits in children diagnosed with Autism. The present paper modified the previously used perspective-taking protocol and included story book examples to determine if typically developing children could change perspective from themselves to fictional characters in various children's books using a Relational Frame Theory approach. Previous research suggests that derived relational responding is responsible for perspective-taking deficits. The results of the current study suggest that after extensive training; typically developing children were able to complete the perspective-taking protocol.

Purpose: Pharmacists must ensure the safe and effective use of medication, but often have only the documented patient history to guide assessment of therapy. There is a lack of information on the incidence of claimed drug allergies or the validity of these self-reported drug allergies in the South African population. Mislabelling of patients as being allergic to medication often deprives them of important therapeutic drugs and alternative agents may be more dangerous, less effective and more costly (Hung et al., 1994). The aim of the research was therefore to determine the incidence of drug allergies in patients admitted to a private hospital and to assess the validity of these self-reported drug allergies. Methods: A descriptive, non-experimental study design was used. Data was collected using a concurrent, cross-sectional approach and collected from patients admitted to hospital using Medical Chart Reviews and researcher-led, questionnaire based interviews. During the seven month sampling period, 693 patients were identified with one or more self-reported drug allergies. A subset of 99 patients (14.2%) consented to a researcher-led interview. The allergies were assigned to one of three groups based on the history: (i) High probability: signs and symptoms typical of an immunological reaction. (ii) Low probability: signs and symptoms of the reaction were predictable reactions or side effects of the drug. (iii) Unknown status: no information concerning the reaction history was available. Results: A total of 953 allergies were identified in the 693 patients, with a ratio of drug allergy to patient of 1.4:1. The majority of claimed allergies were to penicillin (39.2%), opioid analgesics (17.6%), other antimicrobials, including co-trimoxazole (13.5%), NSAIDs (9.9%) and unspecified “sulphur” allergy (8.7%). Descriptions of the “allergic” reactions were only recorded on 8.9% (62, n=693) of the reviewed charts. Only 56.5% (35, n=62) of the symptoms recorded as “allergy” were indicative of the event being allergic or immunological in nature. In total, 1.3% (9, n=693) of the patients with a self-reported allergy received the allergen while in hospital. In three cases this was the result of a pharmacist overlooking the recorded allergy, and dispensing the allergen to the patient. A total of 118 allergies were identified in the 99 interviewed patients, with a ratio of drug allergy to patient of 1.2:1. Inaccurate allergy history was found in 9.1% (9, n=99) of the interviewed patients. Overall, the majority of self-reported drug allergies (67.8%) had a “high probability” of being a true drug allergy. Allergies that were assigned into the high probability group were: penicillin (74.1%), co-trimoxazole (91.7%), NSAID‟s (55.6%) and 75.0% of opioids. Conclusion: In summary, the validity of self-reported drug allergies need to be determined before excluding medication from a patient‟s treatment options. Detailed descriptions can assist in the evaluation of self-reported allergies which would be advantageous to both prescribers and patients. Pharmacists need to play a bigger role in ensuring accurate documentation of drug allergy history, with detailed descriptions, in order to ensure safe and effective drug use within the hospital environment.

Within the present study, a multiple probe design across participants was used to analyze the effect of simple and single reversal deictic relational frame training on the rate correct responding to deictic relational frames in individuals with developmental disabilities. Results showed an increase in correct responding to simple and single reversal deictic relational frames after the implementation of the intervention. Furthermore, results showed that mastery level of responding was maintained in both simple and single reversal deictic frames after once training concluded. This research contributes to body of research concerning the training of deictic frames within individuals with developmental disabilities and research concerning the use of training deictic frames using pieces of the PEAK T Curriculum. The strengths, limitations, and methods to account for these issues within future research are discussed.

Perspective taking (PT) is the ability to imagine perspectives that differ from our own. Understanding what others believe (cognitive PT) and feel (affective PT) allows us to better navigate social situations, and understanding what others see (spatial PT) allows us to better navigate spatial environments. Deficits in spatial, cognitive, and affective PT are apparent in several DSM–5 categorized clinical populations including autism spectrum disorder (ASD) and major depressive disorder (MDD). Further, differences in the severity of PT impairments may be related to general mechanisms that support this ability rather than diagnostic categories. However, the general cognitive mechanisms that support PT and whether spatial, cognitive, and affective PT share behavioral co-variance and rely on common neural mechanisms is not yet understood. There are at least two theoretical accounts regarding the association of spatial, cognitive, and affective PT. Common mechanisms accounts propose that the three types of PT are associated because all rely on manipulation of frame-of-reference representations coordinated by dorsal and ventral attentional networks. Alternative proposals suggest that attentional mechanisms support spatial PT, but cognitive and affective PT are supported by a distinct module for mental state reasoning. In this dissertation, I begin by summarizing prior evidence from studies which examined the developmental emergence of PT abilities, behavioral co-variance of PT in neurotypical and clinically diagnosed adults, and neuroimaging studies of PT. Review of the literature indicates mixed findings with support for both common and distinct mechanisms accounts. Thus, the present work probes the association of spatial, cognitive, and affective PT across two experiments. In Experiment 1, a systematic activation likelihood estimation meta-analysis of spatial, cognitive, and affective PT and attention switching was conducted. Results indicated no single neural region that was commonly associated with all three types of PT, but several overlapping regions among cognitive and affective PT, and separately among spatial PT and attention switching. In Experiment 2, two behavioral tasks and one self-report measure each of spatial, cognitive, and affective PT, a behavioral measure of attention and general reasoning ability were administered to large sample of young adults. Performance on spatial PT tasks did not significantly covary with cognitive PT, attention, nor two of the three affective PT measures in neurotypical adults. In sum, neural and behavioral experiments provided substantial support for distinct mechanisms accounts and only limited support for common mechanisms accounts of PT in neurotypical adults. / Psychology
