An alternative model to describe decision-making in these conditions is the recognition-primed decision-making (RPD) model (Klein, 1989). This model is descriptive and suggests that expert decision-makers learn to recognise typical situations and solutions and use these mental shortcuts to fill in gaps in their understanding and inform their decisionmaking. The model has been validated in many domains (Klein, 1999), but to date has not been applied in the Australian Army. Moreover, the model has been criticised because it largely ignores the influence of the wider context in dynamic decision-making. The aim of this research is to address these issues. The setting has been the unit level of operations in the Australian Army. In particular, the focus is on the Commander, as slhe has the largest impact on the strategic direction of an operation. The approach combines a number of complementary data collection methods, drawing on both qualitative and quantitative data. The main methods of data collection include in-depth, semi-structured interviewing; Q-sort analysis; and observational research in the field. These are triangulated to increase validity. Computer simulation is also used to investigate its adequacy for further naturalistic decision-making (NDM) research. The outcome is frrstly a validation of the RPD model in the Australian Army and revision to include contextual variables perceived to impact on NDM. The effect of these contextual variables on RPD requires further research using naturalistic techniques. Computer simulation has been found to be an unsatisfactory technique to employ in this instance. These are important outcomes as the Australian Army moves towards an era of Networked Centric Warfare where established structures for team work are being revised. Establishing a better understanding of contextual factors that impact on NDM enables policy makers to take this knowledge into account when hypothesising about the effect that structural changes might have on business processes. Thus, having better defined models, and research techniques identified to achieve this, is a benefit. / http://proxy.library.adelaide.edu.au/login?url= http://library.adelaide.edu.au/cgi-bin/Pwebrecon.cgi?BBID=1277501 / Thesis (Ph.D.) -- University of Adelaide, School of Psychology, 2007

The research within this thesis has been concerned with the concept of individual lability and how this may impact the occurrence of psychokinetic (PK) effects. Although frequently used as a descriptor within the fields of psychology, parapsychology has attempted to explore individual lability as a construct in its own right. Defined as an 'ease of change', within parapsychological research individual lability has been afforded the ability to either act as a contributing or mediating factor in the production of PK effects. To that effect, a major concern for this thesis was to operationalize the construct of individual lability via the development of a psychometric measure - an initial Lability Scale and then a further Revised Lability Scale. In order to make sense of the theoretical assumptions about individual lability this thesis explores the background of the production of PK effects in both real-world and experimental environments. It identifies shared individual elements in the reports of PK effects relating to heightened arousal, neurological activity, personality traits, emotional states and creativity that may help to identify multiple dimensions of individual lability. Drawing on the perspectives of lability models which emphasize an interaction between differing lability levels of random systems as a predictor of PK effects, it is suggested that successful outcomes are more likely between high levels of one system and low levels of another system. For the purposes of the three empirical studies a Random Number Generator (RNG) with different levels of Table, Pseudo and Live were employed to explore this interaction. An initial online survey consisting of measures of creative, neurological, state and Openness to Experience enabled the creation of the 71-item, 5 factor Lability Scale (LS) using factor analysis. Factors were defined as: Intuitive Cognition, Conceptual Cognition, Ego-Orientated Cognition, Emotional Interpretation and Analytical Cognition. The LS had good internal reliability and did not correlate with additional measures of anomalous experience and PK experiences, thus demonstrating face-value validity. The LS was subsequently employed in a series of three PK-RNG experiments exploring the lability interaction which incorporated a standardised design of a computerised I Ching task measured using the Q-sort method and separate group samples (N = 50). Study One included the impact of perceived stress, Study Two included the impact of the participant/research interaction, Study Three included the impact of goal-orientated striving. The primary hypothesis that levels of individual lability (Low, Medium, High) would significantly interact with Q-sort ratings of RNG system lability was not supported for all three experiments. In addition, the impact of the additional variables was non-significant. However, significant correlations were found between all of the LS factors apart from Analytical Cognition. It was also observed that there was a significant difference between lability levels between genders, with males on average having lower lability levels. In addition, a final analysis combining the individual and RNG lability data from all three studies was conducted, although there was also no significant interaction effect found between levels of individual and RNG lability. However, following the consistent lack of response from the Analytical Cognition factor it was deemed necessary to psychometrically refine the Lability Scale further. Therefore, a second factor analysis was conducted on the combined experimental data (N = 147) and the 32-item, 3 factor Revised Lability Scale was developed. Three identified factors were defined as: Creative Expression, Emotional Interpretation and Spiritual Interpretation. It was noted that the factor structure was somewhat reversed to that of the initial LS but the majority of items remained consistent. However, analysis showed that there was no interaction found between levels of individual lability and RNG lability. There were significant relationships between Creative Expression and Table RNG and Pseudo RNG lability levels. In addition, consistent difference between the genders in relation to the three factors were found with large effect sizes, with males having significantly lower levels overall. The final Discussion questioned the lack of significant findings for the lability PK-RNG interaction in relation to the complexity of the methodology and the multiple variables introduced in the empirical studies.

Self-reports have described luck as an important factor in people’s lives, and there is a sizable body of psychological research conducted around the belief in luck, primarily as an intangible external element and a companion of gamblers. This thesis reviews the major part of this research, offering a critical analysis and identifying a region of research into luck that warrants further investigation. That is, if psychic events, collectively termed ‘psi’ are possible then such events may just appear to be lucky. Several parapsychological studies have investigated this relationship between luck and psi but have failed to discern if this relationship is real, perhaps because of the lack of explicit definition of luck or the measurement of what it is that the participants believe it to be. To address this issue existing luck belief measures were reviewed but it was clearly necessary to construct a new comprehensive measure based on thorough bottom-up test construction principles. A series of semi-structured interviews about luck were reanalysed qualitatively, the themes of which were used in the generation of items for a questionnaire. Through a series of factor-analyses a final 40-item, 4-factor Questionnaire of Beliefs about Luck (QBL) was produced, with factors labelled Luck, Chance, Providence and Fortune, to which was added a 1-item measure of Perceived Personal Luckiness (PPL). The new measure was found to be robust and internally reliable and correlated with paranormal belief supporting several predictions and thereby demonstrating sound construct validity. The literature on psi and luck indicated that luck might best be understood by Stanford’s (1974a) model of ‘psi-mediated instrumental response’ (PMIR) and a PMIR-type study was planned which incorporated the new QBL. A non-intentional precognition experiment with 100 participants utilised erotic-images as psi incentives and found good evidence of psi with this design. Furthermore, the QBL Luck subscale was found to be a significant predictor variable of psi score, indicating that the measure has good predictive validity, and PPL, belief in psi, and erotic reactivity also correlated with psi scores. There was also a near gender-effect. The findings were discussed in light of previous results and were interpreted in relation to the psychological theories outlined in the literature review, finding support for the notion of self-serving biases, and offering fresh insights into the illusion of control. A model was put forward for the relationship of luck and psi. It was concluded that the QBL was a comprehensive, reliable, valid and useful tool in the investigation of luck

In this PhD research a question is posed that concerns ‘varieties of creativity’ that have infrequently been explored empirically, although often described anecdotally. This question being: is, and if so, how, is creativity related to altered states of consciousness (ASCs) and parapsychological experiences? This thesis systematically explores the relationship between multiple dimensions of creativity and: personality traits characterised by an openness to intrapersonal experience and a fluid cognitive-style; specific altered states of consciousness and anomalous experiences (such as mystical experiences and subjective paranormal experiences); and anomalous cognition. The common thread is conceived as an examination of the extent to which creativity might involve ‘epistemological flexibility’ — that is, involves shifts into, and between, different ‘ways of knowing’. As such, a major part of this thesis was the psychometric development of a new self-report instrument, the Creative Cognition Inventory, which measures the reported use of different epistemological resources (such as intuition, dreams and rational logic) in the creative process. Creativity is defined in terms of a process, participated in at the person-level, which leads to a novel and adaptive product or performance. Drawing upon models of the creative process and person, it is suggested that a biphasic process is common to most theories of creativity, and that individuals with particular traits have been hypothesised to engage in this with more facility. Models that have explored cognitive, affective and perceptual ‘looseness’ as facilitating novelty are examined. As altered states of consciousness involve subjective shifts in these same dimensions, it is proposed that creativity and ASCs may be experientially related, either directly, or in terms of an overarching trait, such as ‘boundary-thinness’ or ‘transliminality’, which propitiates both. A multi-dimensional approach was taken to creativity measurement, accepting its complexity as a componential construct that might consist of multiple creativities. In Study One, the benefits of a multidimensional approach to creativity measurement were evident, refuting earlier work that had used only cognitive estimates of creativity and found no relationship with either boundary-thinness or transliminality. These constructs are experiential-traits that assess ones degree of intrapersonal openness, cognitive fluidity and sensitivity, and are associated with a proclivity to have unusual experiences. In Study One, they were found to be significantly correlated with both domain general measures of creativity (creative personality) and domain specific measures (emotional creativity and involvement in the arts). The sample for Study One consisted of 65 psychology undergraduates (49 females; 16 males). A second study assessed the degree to which different dimensions of creativity were related to different experiences of consciousness. 211 participants were recruited from the general population through opportunity sampling (108 females; 101 males). The sample included professional artists (n = 36) and scientists (n = 27). Competing models of a relationship between creativity and ASC-proclivity were assessed: cognitive expansion; affective openness; and motivational impetus. This study provided numerous insights into the experiences of consciousness that might be related to varieties of creativity. The key findings were that emotional creativity was most robustly associated with ASCs; artistic creative-personality was associated with ‘positive’ ASCs, including those along an oneiric continuum (e.g. hypnagogia and hallucinations), and those along an affective expansion continuum (e.g. dissociation and positive mystical experiences). Further, original and flexible cognition appeared to be associated with states along an oneiric continuum. Thus, Study Two found support for the affective and cognitive models, yet within different ranges of experience. This ‘model’ helps to clarify, by using heterogeneous, rather than homogenous constructs of ‘unusual experiences’, specific processes by which ASCs and creativity may be related and as such deserves further exploration. The final piece of research developed a novel protocol for recording impressions thought by participants to involve extrasensory perception (ESP) and associated states of consciousness in daily life, using experience- sampling methodology. As success in ESP experiments has consistently been reported amongst visual artists, the above models were used to explore what aspects of the creativity complex might be associated with ESP-performance. As only emotional creativity related to the reporting of parapsychological experiences in Study Two, the affective openness model was expected to predict ESP-performance. Further, a carefully matched control group (n = 15) was used against which to compare success of artists (n = 15). Artists did not demonstrate a superior ESP effect in this study, although they did perform at a level commensurate with previous research. The affective openness hypothesis for ESP performance was rejected. Rather, it was questioned whether previous studies had not adequately matched controls or that the ‘take-home’ methodology, perhaps increasing relaxation and control for the participants, increased performance levels for the non-artists

Although psychical research identified through structured research the commonality of anomalous experiences for the bereaved from as early as the 1880s, it wasn’t until the 1970s with the publication of a medical doctorate on such phenomena that medical communities and social science began to recognise them too. Beyond this point, research became more popular on the subject. Extensive research conducted on post-death experiences (aka, Post-Death Contacts – ADCs) since the 1970s, has largely focused on what impact they have on the bereaved, rather than the ontology of the phenomena themselves. All such studies have found these experiences to be therapeutic for the bereaved, and a natural aid to recovery. However, no research findings to this point have been presented on what cognitive mechanisms create the therapeutic gains experienced, as a direct result of the spontaneous anomalous experiences. This thesis set out to investigate what makes such experience therapeutic, and aid the process of recovery from grief. From a critical review of the previous literature, it was noted that several of the extensive studies, and related popular literature, identified hope to a consistent reported outcome of such experiences. However, no existing studies appeared to have investigated its presence and process in this context. Therefore, a mixed method study design was developed to investigate the impact of such experiences further and the role of hope within them. A questionnaire approach of validated scales found levels of hope to be significantly higher in groups of the bereaved who do report post-death experience than those who don’t. The bereaved who do not report such experiences appear to encounter a significant drop in hope. Content and thematic analyses were conducted on written feedback of experiences collected from the questionnaires; this highlighted the variety of experiences and their commonality. It also highlighted significant shifts in ‘states of mind’ from negative to positive emotions, from the point of loss, to following the first anomalous encounter. Continued bonds with the deceased were also expressed, as well as previously noted therapeutic gains and themes of hope. In-depth interviews were conducted as the final study of this thesis, with an interpretative phenomenological analysis applied to the data. New findings are presented on the personal changes that take place within post-death events. Experients defined hope and how they saw it acting within their lives and experiences as a support system to feelings of loss, which fell in line with previous positive psychology theories on hope. Several key points are concluded. Firstly, the findings of this thesis have practical applications to clinical practice surrounding palliative care and applied positive psychology, regarding the importance of anomalous experiences encountered by the bereaved. Secondly, the thesis and its findings demonstrate the multi-disciplinary approaches which can be taken to parapsychological issues, in this case combining positive psychology, thanatology and healthcare. And finally, the thesis highlights the usefulness of the mixed method approaches, to provide ‘sweeping maps’ of any given phenomena under investigation, particularly in cases where the previous research findings are limited or are yet to be explored.

Bibliography: pages 299-316. / Professional staff attached to Child Welfare in Cape Town are aware of the lack of academic attainment of a large number of children in alternative care. The current research investigated the relationship between scholastic performance and neuropsychological functioning in a sample of institutionalised children from culturally deprived families. A multiple case study of 21 children, ranging in age from 6 to 16 years, comprising 10 girls and 11 boys attending the same primary school, provided data on neuropsychological, behavioural and family history dimensions. A multi-model assessment approach tapped diverse sources of evidence, including the following 5 parameters: 1) The Sensory Parameter: Snellen's Visual Acuity test, and either Merryweather & Steenkamp's or Wepman's Auditory Discrimination tests. 2) The Motor Parameter: Denckla's Revised Neurological Examination for Subtle Signs and the Purdue Pegboard fine motor speed and coordination tests. 3) The Language Parameter: The UCT Graded Reading, Speed Reading and Graded Spelling tests. 4) The Integrative Parameter: Visuographic functioning included the Beery Developmental Test of Visual-Motor Integration, the Goodenough-Harris Drawing Test and the WISC-R Mazes subtest. General intelligence was assessed using the Wechsler Intelligence Scale for Children - Revised. Memory function was gauged both by the Benton Visual Retention Test (multiple choice format) and the WISC-R Digit Span subtest. Concentration was examined by combining 3 WISC-R subtest measures (Arithmetic, Digit Span & Coding) to yield a "Freedom from Distractibility" index. 5) The Personal Parameter: This included details of the children's heights and weights, as well as information regarding their self-concepts, measured by the Attitudes Towards Self Scale, a semantic differential self-report scale, developed by Nieuwoldt & Cronje. Written responses to 2 projective techniques, which included Wish fulfilment and Incomplete sentences, provided material for content analyses that yielded insights into attitudes to a variety of topics, including school, family life, hopes and fears.

Infant vocalisations are uniquely salient sounds in the environment. They universally attract attention and compel the listener to respond with speed and care. They provide a wealth of information to parents about their infant’s needs and affective state. There is a scientific consensus that early parenting has a profound impact on child development. In particular, the sensitivity with which parents respond to their infant’s communicative cues has been shown to affect cognitive and socio-emotional outcomes. The mechanisms underlying such sensitivity are not well understood. In this thesis, adults’ sensitivity to infant cues will be considered in terms of two components, the ‘promptness’ and ‘appropriateness’ of responses, as originally conceptualised by Bell and Ainsworth (1972). Promptness of responses is considered in terms of adults’ ability to move with speed and effort after listening to infant vocalisations. Appropriateness, on the other hand, is considered in terms of adults’ ability to differentiate between functionally significant parameters in infant vocalisations. The effect of modifiable environmental factors on the promptness and appropriateness of responses is also investigated. Finally, a focused investigation of the brain basis of responses to infant vocalisations is presented. Overall, findings demonstrated that infant vocalisations undergo privileged, specialised processing in the adult brain. After hearing an infant cry, adults with and without depression were found to move with greater coordination and effort. Adults were also found to be attuned to subtle parameters in infant cries. This sensitivity was shown to be affected by two participant-level factors, depression and previous musical training. Furthermore, this sensitivity could be enhanced through intervention, as evidenced by findings from short-term, perceptual discrimination training. The notion of privileged processing of infant vocalisations is further supported by evidence of early discrimination of infant sounds in a survival-related subcortical brain structure. Future directions for this work include directly relating current experimental measures of adults’ responses to infant cues with parental sensitivity to infant communication during dynamic interactions. Translating current findings into applied settings would require an investigation of the effects of factors such as musical and perceptual training on sensitivity to infant cues in at-risk populations, such as mothers and fathers with depression. Lastly, an increased understanding of the brain basis of adults’ sensitivity to infant cues will provide insight into our greatest challenge: parenting our young.

This paper presents 12 individual case studies representing three different psychiatric diagnoses: depression, schizophrenia, and phobia. The collected data suggests that aspects of each one of the disorders covered are somehow reflected in the dreams and dream existence of the patients. Based on repeated in-depth interviews (n=48) with each of the participants (n=12), it is clear that dream content often repeats in each individual. Further phenomenological and qualitative content analysis revealed repetition of characteristic dream content (feelings, phenomenon, and existentials) in each of the three groups. While more research is needed, the results suggest dream content could be a significant tool in establishing a diagnosis and in aiding the psycho-therapeutic process.
