Intrusions in trauma and psychosis: information processing and phenomenology

Background: Intrusions are common symptoms of both posttraumatic stress disorder (PTSD) and schizophrenia. Steel et al (2005) suggest that an information processing style characterized by weak trait contextual integration renders psychotic individuals vulnerable to intrusive experiences. This ‘contextual integration hypothesis’ was tested in individuals reporting anomalous experiences in the absence of a need-for-care. Methods: Twenty-six low schizotypes and twenty-three individuals reporting anomalous experiences were shown a traumatic film with and without a concurrent visuo-spatial task. Participants rated post-traumatic intrusions for frequency and form, and completed self-report measures of information processing style. It was predicted that, due to their weaker trait contextual integration, the anomalous experiences group would (1) exhibit more intrusions following exposure to the trauma-film; (2) display intrusions characterised by more PTSD qualities and (3) show a greater reduction of intrusions with the concurrent visuo-spatial task. Results: As predicted, the anomalous experiences group reported a lower level of trait contextual integration and more intrusions than the low schizotypes, both immediately after watching the film, and during the following seven days. Their post-traumatic intrusive memories were more PTSD-like (more intrusive, vivid and associated with emotion). The visuo-spatial task had no effect on number of intrusions in either group. Conclusions: These findings provide some support for the proposal that weak trait contextual integration underlies the development of intrusions within both PTSD and psychosis.

Spectral nonlocality, absolute equilibria and Kraichnan-Leith-Batchelor phenomenology in two-dimensional turbulent energy cascades

We study the degree to which Kraichnan–Leith–Batchelor (KLB) phenomenology describes two-dimensional energy cascades in α turbulence, governed by ∂θ/∂t+J(ψ,θ)=ν∇2θ+f, where θ=(−Δ)α/2ψ is generalized vorticity, and ψ^(k)=k−αθ^(k) in Fourier space. These models differ in spectral non-locality, and include surface quasigeostrophic flow (α=1), regular two-dimensional flow (α=2) and rotating shallow flow (α=3), which is the isotropic limit of a mantle convection model. We re-examine arguments for dual inverse energy and direct enstrophy cascades, including Fjørtoft analysis, which we extend to general α, and point out their limitations. Using an α-dependent eddy-damped quasinormal Markovian (EDQNM) closure, we seek self-similar inertial range solutions and study their characteristics. Our present focus is not on coherent structures, which the EDQNM filters out, but on any self-similar and approximately Gaussian turbulent component that may exist in the flow and be described by KLB phenomenology. For this, the EDQNM is an appropriate tool. Non-local triads contribute increasingly to the energy flux as α increases. More importantly, the energy cascade is downscale in the self-similar inertial range for 2.5<α<10. At α=2.5 and α=10, the KLB spectra correspond, respectively, to enstrophy and energy equipartition, and the triad energy transfers and flux vanish identically. Eddy turnover time and strain rate arguments suggest the inverse energy cascade should obey KLB phenomenology and be self-similar for α<4. However, downscale energy flux in the EDQNM self-similar inertial range for α>2.5 leads us to predict that any inverse cascade for α≥2.5 will not exhibit KLB phenomenology, and specifically the KLB energy spectrum. Numerical simulations confirm this: the inverse cascade energy spectrum for α≥2.5 is significantly steeper than the KLB prediction, while for α<2.5 we obtain the KLB spectrum.

A theoretical discussion about the clinical value of phenomenology for nurses

This article develops a theoretical discussion related to the value of a phenomenological framework in contributing to contemporary nursing knowledge. Nursing is based on the understanding of patients' personal experiences and their responses to their illness. Phenomenological methodology utilizes the patient's own language to reflect meanings embedded in their health experience.

Telling it how it really is? : life in organisations revealed using Heideggerian phenomenology

Heideggerian phenomenology is expounded here as a qualitative methodology of value in researching "how things really are" in organisational life. It is a methodology, and a philosophy, which recognises a priori the value ofthe subjective, lived experience of the informant, and the physical, sociological and psychological phenomena that come together to create their life-world. In this paper, the authors present cases where this methodology successfully revealed the respondents' reality. Stories about working in teams and being downsized are shared to demonstrate the ability of Heideggerian phenomenology to reveal how life really is in organisations.

The effect of Shamanic-like stimulus conditions and the cognitive-perceptual factor of schizotypy on phenomenology

Shamanism has remained an integral part of indigenous healing rituals since ancient times and is currently attracting interest as a complementary therapeutic technique in psychology. Recently, shamanic-like techniques have been used to facilitate changes in the phenomenology of nonshamans. However, such research has largely been delimited to a single shamanic-like technique (i.e., drumming), and the role of personality traits with regards to receptivity to this technique has been neglected. The purpose of the present study was to investigate experimentally the effect of different shamanic-like techniques and the cognitive-perceptual factor of the schizotypy construct on phenomenology. One hundred and four non-shamans were randomly assigned to one of three conditions: Drumming, Ganzfeld, or Sitting Quietly with Eyes Open. Participants' phenomenology was assessed using the Phenomenology of Consciousness Inventory, Phenomenology associated with shamanic-like techniques appeared to be statistically significantly different from phenomenology associated with sitting quietly with eyes open. Furthermore, high cognitive-perceptual participants reported significant alterations in phenomenology compared to their low cognitive-perceptual counterparts. Methodological shortcomings of the present study are discussed and suggestions for future research are advanced.

The phenomenology of being-meditative

This thesis addresses the experience of being-meditative using a philosophical perspective. It discloses the ontological dynamics of meditative-Dasein and reveals the meditative modes of being-at-rest, a cultural and social mode of being, whose perceptual intentionality is unified by the authentic Care for Being, thereby enabling a Homecoming.

Phenomenology and the online : the importance of studying experience

 Phenomenological research into the online experience offers real value to Internet Studies and Digital Humanities scholars for three key reasons. Firstly, as an explicitly qualitative approach, it offers a way to gain insights into the experience of going online that are not identified by those who study behaviour alone. Secondly, as phenomenological studies focus on the individual rather than the collective, the resulting small sample size means that the investment required in terms of time spent with participants is minimised. Finally, the interpretation that emerges through the phenomenological research process produces categorisations that could form the basis on which larger scale, Big Data, quantitative research projects could be built.
This paper will explore the above ideas through the lens of my doctoral research, which uses hermeneutic phenomenology to investigate the experience of persona construction by artists on the fringes of the traditional art world, specifically craftivists, tattoo artists, street artists, and performance poets. By incorporating the interpretive categorisations that have come from my early discussions, I will demonstrate the strength of a phenomenological approach to investigating the experience of using the world and social media to present the self to the world.
