Dogmatism and the distinctiveness of opposite v. different cognitive system: release from proactive inhibition for shifts within- and between-dimensions of meaning

In a series of three experiments, encoding distinctiveness in a release from proactive inhibition paradigm was investigated as a function of dogmatism. Significant differences in release from proactive inhibition between high and low dogmatic individuals were found for shifts within meaning dimensions (from one end of a dimension to the other end) but not for shifts between different dimensions of meaning. The results were discussed in terms of the emphasis on belief vs. disbelief systems in dogmatism, motivational processes in cognition, and recent work on differences in social cognition

Irrational beliefs and unconditional self-acceptance. II. Experimental evidence linking two key features of REBT

In a test of two key features of REBT, causal relationships between irrational beliefs and unconditional self-acceptance were experimentally investigated in a sample of 106 non-clinical participants using a priming technique. Priming participants with statements of irrational belief resulted in a decrease in unconditional self-acceptance whereas priming participants with statements of rational belief resulted in an increase in unconditional self-acceptance. In contrast, priming participants with statements about unconditional self-acceptance did not result in an increase in rational thinking and priming participants with statements about conditional self-acceptance did not result in an increase in irrational thinking. The present study is the first to provide evidence of a causal link between rational/irrational thinking and unconditional/conditional self-acceptance. The findings have important implications for the core hypothesis of REBT and underscore the advantages of experimental over correlational studies in theory-testing

Personality: two ways of thinking about it. Hans Eysenck Lecture

In his Hans Eysenck Lecture, Martin Davies describes how he has continued to integrate the correlational and experimental in the study of personality and cognition. \ud Introduction: HANS Eysenck was one of the first people to combine what Cronbach (1957) called the two disciplines of scientific psychology – the correlational and the experimental. In this article I’ll describe my own correlational and experimental research into the role of confirmatory processing in personality questionnaire responding, and how cognitive styles such as dogmatism influence confirmatory processing. I aim to show why I believe Eysenck was right – the two disciplines need to be unified before psychology becomes a truly scientific paradigm

Rotating gravity currents: small-scale and large-scale laboratory experiments and a geostrophic model

Laboratory experiments simulating gravity-driven coastal surface currents produced by estuarine fresh-water discharges into the ocean are discussed. The currents are generated inside a rotating tank filled with salt water by the continuous release of buoyant fresh water from a small source at the fluid surface. The height, the width and the length of the currents are studied as a function of the background rotation rate, the volumetric discharge rate and the density difference at the source. Two complementary experimental data sets are discussed and compared with each other. One set of experiments was carried out in a tank of diameter 1 m on a small-scale rotating turntable. The second set of experiments was conducted at the large-scale Coriolis Facility (LEGI, Grenoble) which has a tank of diameter 13 m. A simple geostrophic model predicting the current height, width and propagation velocity is developed. The experiments and the model are compared with each other in terms of a set of non-dimensional parameters identified in the theoretical analysis of the problem. These parameters enable the corresponding data of the large-scale and the small-scale experiments to be collapsed onto a single line. Good agreement between the model and the experiments is found

Rational and irrational thinking in terrorist pronouncements: An REBT analysis.

The objective of this study was to explore the thinking of terrorist groups from a content analysis of terrorist pronouncements obtained from the Web. Five main themes were identified: The explicit aims of the group; Oppression; A noble/holy war; Extreme ingroup-outgroup contrasts; and a higher, greater force. These themes were analysed from an REBT perspective. Although there was evidence of rational thinking especially in the aims of the group, the remaining themes exhibited thinking that emphasised demands, downing and low frustration tolerance

An experimental test of a core REBT hypothesis: evidence that irrational beliefs lead to physiological as well as psychological arousal.

While numerous studies support Rational Emotive Behavior Therapy and Theory (REBT), they tend to be limited by their use of correlational designs, simulated scenarios and self-report measures. This study tested a core REBT hypothesis in an experimental design using multiple pshysiological as well as psychological measures. Ninety patients from a medical practice were placed in a real-life stressful situation while holding either a rational, an irrational, or an indifference belief. Those holding a rational belief reported the greatest increase in anxiety. Of particular significance, those holding a rational belief showed a decrease in systolic blood pressure whereas those holding an irrational belief showed an increase (diastolic blood pressure increased in both conditions). These results not only support the core REBT hypothesis, but also suggest a way to differentiate between beliefs and emotions by measuring physiological as well as psychological changes

Affective reactions to auditory hallucinations in psychotic, evangelical and control groups

Objectives: Building on recent work on the similarities and differenes in delusional ideation between psychotic and religious populations (Peters, Day, McKenna, and Orbach, 1999), the experiences of auditory hallucinations in psychotic, evangelical and control groups were examined in this study. -- Method: The incidence and subjective experiences of hearing voices were assessed using questionnaire methods in psychotic out-patients, evangelical Christians and controls (non-psychotic, non-evangelical). -- Results: Incidence of auditory hallucinations differend significantly across the three groups with psychotics showing the highest levels and controls the lowest levels. The experiences of the evangelical group were significantly more positive than those of the control group, which in turn were significantly more positive than those of the psychotic group. The most recent experience of hearing voices was rated more positively than the first experience by the psychotic and religious groups but not by the control group. These findings were much stronger for affective reactions to the experiences than for perceptions of the voices. -- Conclusion: These results provide only partial support for the findings of Peters et al. (1999) on differences in delusional ideation and possible reasons for this are discussed. The findings for religious and psychotic individuals are discussed further in terms of interpretational and coping mechanisms

Effective health care for older people resident in care homes: the optimal study protocol for realist review

The Creative Commons Public Domain Dedication waiver (http://creativecommons.org/publicdomain/zero/1.0/) applies to the data made available in this article, unless otherwise stated.Background: Care homes in the UK rely on general practice for access to specialist medical and nursing care as well as referral to therapists and secondary care. Service delivery to care homes is highly variable in both quantity and quality. This variability is also evident in the commissioning and organisation of care home-specific services that range from the payment of incentives to general practitioners (GPs) to visit care homes, to the creation of care home specialist teams and outreach services run by geriatricians. No primary studies or systematic reviews have robustly evaluated the impact of these different approaches on organisation and resident-level outcomes. Our aim is to identify factors which may explain the perceived or demonstrated effectiveness of programmes to improve health-related outcomes in older people living in care homes. Methods/Design: A realist review approach will be used to develop a theoretical understanding of what works when, why and in what circumstances. Elements of service models of interest include those that focus on assessment and management of residents’ health, those that use strategies to encourage closer working between visiting health care providers and care home staff, and those that address system-wide issues about access to assessment and treatment. These will include studies on continence, dignity, and speech and language assessment as well as interventions to promote person centred dementia care, improve strength and mobility, and nutrition. The impact of these interventions and their different mechanisms will be considered in relation to five key outcomes: residents’ medication use, use of out of hours’ services, hospital admissions (including use of Accident and Emergency) and length of hospital stay, costs and user satisfaction. An iterative three-stage approach will be undertaken that is stakeholder-driven and optimises the knowledge and networks of the research team. Discussion: This realist review will explore why and for whom different approaches to providing health care to residents in care homes improves access to health care in the five areas of interest. It will inform commissioning decisions and be the basis for further research.

Reply to comment on the paper by Davies et al. “Resolving MISS conceptions and misconceptions: A geological approach to sedimentary surface textures generated by microbial and abiotic processes”

We thank Noffke (2017) for her comment and for providing an opportunity to clarify our classification of “sedimentary surface textures”. We accord great credit to Dr. Noffke and other dedicated researchers whose detailed work has brought microbially induced sedimentary structures (MISS) to the widespread attention of geoscientists. However, we stand by our assertion that attributing structures observed in practical field and laboratory studies to processes of formation is much more problematic than Noffke (2017) indicates. Indeed, points in the Comment confirm the need for a classification system that categorises the degree of certainty attributed to a given interpretation. We stress that our paper was not designed as a critique of previous studies of MISS but rather was designed to encourage a reasonable assessment of uncertainty in assigning sedimentary surface textures to physical processes or to MISS
