The cognitive and personality differences of supernatural belief.
This thesis set out to meet the following aim and objectives: Aim: Examine cognition and personality of people who hold different types of supernatural belief. Objective 1: Create and validate a new scale to measure supernatural belief. Objective 2: Create and test a new model of supernatural belief based on cognition and personality. This would potentially test two hypotheses: the Cognitive Deficits Hypothesis and the Psychodynamics Functions Hypothesis. This was accomplished by conducting four studies. Studies one and two created and validated the new Belief in the Supernatural Scale (BitSS), a 44 item scale with the following five factors: âmental and psychic phenomenaâ, âreligious beliefâ, âpsychokinesisâ, âsupernatural entitiesâ, and âcommon paranormal perceptionsâ. Cognition and personality would be looked at within the context of four different types of believer: âbelieversâ, âparanormal believersâ, âscepticsâ and âreligious believersâ. Study three revealed two profiles relating to cognition: âreflective thinkersâ and âintuitive believersâ. The reflective profile was more likely to contain âscepticsâ and âbelieversâ, and least likely to contain âparanormal believersâ. The intuitive group was more likely to contain âreligious believersâ and âbelieversâ. The final study looked at personality alongside cognition and revealed âsensitive and abstract thinkersâ and âreflective metacognitive dogmatistsâ profiles. The âsensitive and abstract thinkersâ were least likely to contain âscepticsâ and âreligious believersâ and most likely to contain âbelieversâ and âparanormal believersâ. The âreflective metacognitive dogmatistsâ were most likely to contain âreligious believersâ and âbelieversâ and least likely to contain âparanormal believersâ. Following this analysis, Structural Equation Modelling was used to test seven different models of personality, cognition and belief. Studies one and two indicated a clear separation of religious and paranormal belief within the new scale, and that spiritual belief overlaps between the two. The scale developed was reliable and valid, and accurately reflected the concept of supernatural belief and enabled the measurement of religious and paranormal belief, where the overlaps were acknowledged whilst still being separate beliefs. Studies three and four found the âscepticsâ and âreligious believersâ have remarkably similar profiles, indicating that the religious beliefs themselves may have been cognitively ring-fenced off in some way. The âparanormal believersâ however were not reflective thinkers and were not metacognitively active, indicating that they were not aware that they were not thinking critically or analytically. The Structural Equation Model showed that schizotypy was the main predictor of belief. The relationship between belief and cognition was more complex; it was dependent on what type of belief was active. Paranormal belief required a more intuitive thinking style to be present, whereas religious belief could withstand a reflective mind set. This thesis develops a new scale that measures supernatural belief provides a unique contribution to knowledge by establishing a model of cognition, personality and belief.the Bial Foundation, Porto (Grant Number: 355/14)
Dissociative tendencies, sensory processing sensitivity and aberrant salience as predictors of anomalous experiences and paranormal attributions.
An online survey completed by 307 adults was undertaken to examine the relationship between the reporting of parapsychological experiences and three psychological dimensions, namely dissociative tendencies, sensory-processing sensitivity and aberrant salience. In contrast with most previous studies of parapsychological experiences, cognizance was taken of a distinction between a proneness to have anomalous experiences and a proneness to attribute such experiences to paranormal factors. All three psychological predictors were found to be related both to a proneness to anomalous experiences and to a proneness to paranormal attributions. Possible implications of these findings for the basis of parapsychological experiences are indicated
Assessing Domain Specificity in the Measurement of Mathematics Calculation Anxiety
An online, cross-sectional approach was taken, including an opportunity sample of 160 undergraduate students from a university in the Midlands, UK. Exploratory factor analysis indicated a parsimonious, four-factor solution: abstract maths anxiety, statistics probability anxiety, statistics calculation anxiety, and numerical calculation anxiety. The results support previous evidence for the existence of a separate ânumerical anxietyâ or âarithmetic computationâ anxiety component of maths anxiety and also support the existence of anxiety that is specific to more abstract maths. This is the first study to consider the multidimensionality of maths anxiety at the level of the calculation type. The 26-item Maths Calculation Anxiety Scale appears to be a useful measurement tool in the context of maths calculation specifically.N/
Mental representations of the supernatural: A cluster analysis of religiosity, spirituality and paranormal belief
The aim of the study was to establish a new typology of belief in the supernatural; categorising people, based on their levels of religiosity, spirituality and paranormal belief. Examining how the various beliefs are defined was a further objective. The reasons for people having different levels of these beliefs were discussed, highlighting âMetaphysical Chauvinismâ as a possible explanation. Previous research that used variousmethods to measure religiosity, spirituality and paranormal belief were discussed. Participants (n = 307) completed an online survey consisting of the revised Religious Life Inventory (rRLI), the Intrinsic Spirituality Scale (ISS) and the revised Paranormal Belief Scale (rPBS). Two cluster analyses were performed: one on the three main scales and a secondary analysis on the ISS, the subscales of the rRLI and the rPBS. The results revealed a four cluster solution for each analysis. For the main analysis the clusters were âbelieversâ, âparanormal believersâ, âscepticsâ and âreligious believersâ. Metaphysical Chauvinism was supported; however, it was acknowledged that there still appears to be a lack of consensus when defining supernatural beliefs. It is proposed that the cluster analysis approach is more effective than a simple scale when trying establish how a person believes

Host reticulocytes provide metabolic reservoirs that can be exploited by malaria parasites
Human malaria parasites proliferate in different erythroid cell types during infection. Whilst Plasmodium vivax exhibits a strong preference for immature reticulocytes, the more pathogenic P. falciparum primarily infects mature erythrocytes. In order to assess if these two cell types offer different growth conditions and relate them to parasite preference, we compared the metabolomes of human and rodent reticulocytes with those of their mature erythrocyte counterparts. Reticulocytes were found to have a more complex, enriched metabolic profile than mature erythrocytes and a higher level of metabolic overlap between reticulocyte resident parasite stages and their host cell. This redundancy was assessed by generating a panel of mutants of the rodent malaria parasite P. berghei with defects in intermediary carbon metabolism (ICM) and pyrimidine biosynthesis known to be important for P. falciparum growth and survival in vitro in mature erythrocytes. P. berghei ICM mutants (pbpepc-, phosphoenolpyruvate carboxylase and pbmdh-, malate dehydrogenase) multiplied in reticulocytes and committed to sexual development like wild type parasites. However, P. berghei pyrimidine biosynthesis mutants (pboprt-, orotate phosphoribosyltransferase and pbompdc-, orotidine 5âČ-monophosphate decarboxylase) were restricted to growth in the youngest forms of reticulocytes and had a severe slow growth phenotype in part resulting from reduced merozoite production. The pbpepc-, pboprt- and pbompdc- mutants retained virulence in mice implying that malaria parasites can partially salvage pyrimidines but failed to complete differentiation to various stages in mosquitoes. These findings suggest that species-specific differences in Plasmodium host cell tropism result in marked differences in the necessity for parasite intrinsic metabolism. These data have implications for drug design when targeting mature erythrocyte or reticulocyte resident parasites
Mental models or probabilistic reasoning or both: Reviewing the evidence for and implications of dual-strategy models of deductive reasoning
The present paper presents an overview of contemporary reasoning research to examine the evidence for and implications of the Dual Strategy Model of Reasoning. The Dual Strategy Model of Reasoning proposes that there are two types of reasoning strategy applied in deductive reasoning â counterexample and statistical. The paper considers Mental Models Theory and The Probability Heuristics Model as candidate specifications for these respective strategies and hypotheses are proposed on this basis. The Dual Strategy Model is further considered in the context of Dual Process theory, the Dual Source Model and Meta-reasoning and implications of the synergy between these proposals are considered. We finally consider the Dual Strategy Model in the context of individual differences, and normative considerations before proposing novel hypotheses and further avenues of research which we argue require exploration in this context.N/
Development and validation of a short-form Pain Medication Attitudes Questionnaire (PMAQ-14)
Attitudes to pain medication are important aspects of adjustment to chronic pain. They are measured by the 47-item Pain Medication Attitudes Questionnaire (PMAQ). To measure those attitudes more quickly and easily, we developed and evaluated a 14-item PMAQ using data from three separate surveys of people with pain in the general population. In survey 1, participants (n=295) completed the 47-item PMAQ and measures of pain, analgesic use, analgesic dependence and attitudes to self-medication. For each of the seven PMAQ scales, the two items that best preserved the content of the parent scales were identified using correlation and regression. The 2-item and parent scales had very similar relationships with other measures, indicating validity had been maintained. The resulting 14-item PMAQ was then completed by participants in survey 2 (n=241) and survey 3 (n=147), along with the same other measures as in survey 1. Confirmatory factor analysis showed that the 14-item PMAQ retained the 7-factor structure of the 47-item version, and correlations with other measures showed it retained the validity of the 47-item version. The PMAQ scale Need was the most significant independent predictor of analgesic dependence in each of four separate multiple regression analyses. This short form of the PMAQ allows attitudes to pain medications to be measured in a valid and more efficient way.Survey 1 was part of Doctoral research undertaken by Omimah Said.

Roars, groans and moans: anatomical correlates of vocal diversity in polygynous deer
Eurasian deer are characterized by the extraordinary diversity of their vocal repertoires. Male sexual calls range from roars with relatively low fundamental frequency (hereafter fo) in red deer Cervus elaphus, to moans with extremely high fo in sika deer Cervus nippon, and almost infrasonic groans with exceptionally low fo in fallow deer Dama dama. Moreover, while both red and fallow males are capable of lowering their formant frequencies during their calls, sika males appear to lack this ability. Female contact calls are also characterized by relatively less pronounced, yet strong interspecific differences. The aim of this study is to examine the anatomical bases of these inter-specific and inter-sexual differences by identifying if the acoustic variation is reflected in corresponding anatomical variation. To do this, we investigated the vocal anatomy of male and female specimens of each of these three species. Across species and sexes, we find that the observed acoustic variability is indeed related to expected corresponding anatomical differences, based on the source-filter theory of vocal production. At the source level, low fo is associated with larger vocal folds, whereas high fo is associated with smaller vocal folds: sika deer have the smallest vocal folds and male fallow deer the largest. Red and sika deer vocal folds do not appear to be sexually dimorphic, while fallow deer exhibit strong sexual dimorphism (after correcting for body size differences). At the filter level, the variability in formants is related to the configuration of the vocal tract: in fallow and red deer, both sexes have evolved a permanently descended larynx (with a resting position of the larynx much lower in males than in females). Both sexes also have the potential for momentary, call-synchronous vocal tract elongation, again more pronounced in males than in females. In contrast, the resting position of the larynx is high in both sexes of sika deer and the potential for further active vocal tract elongation is virtually absent in both sexes. Anatomical evidence suggests an evolutionary reversal in larynx position within sika deer, that is, a secondary larynx ascent. Together, our observations confirm that the observed diversity of vocal behaviour in polygynous deer is supported by strong anatomical differences, highlighting the importance of anatomical specializations in shaping mammalian vocal repertoires. Sexual selection is discussed as a potential evolutionary driver of the observed vocal diversity and sexual dimorphisms
