Dissociation, trauma, and the role of lived experience: toward a new conceptualization of voice hearing

Voice hearing (VH) is often regarded as pathognomic for schizophrenia. The purpose of this article is to review and integrate historical, clinical, epidemiological, and phenomenological evidence in order to suggest that VH may be more appropriately understood as a dissociative rather than a psychotic phenomenon. First, we discuss the lifetime prevalence of VH in the general population, which is estimated to range between 1% and 16% for adult nonclinical populations and 2% and 41% in healthy adolescent samples. Second, we demonstrate how the ubiquity of VH phenomenology, including variables like voice location, content, and frequency, limits its diagnostic and prognostic utility for differentiating psychotic from trauma-spectrum and nonclinical populations. Finally, we report on the empirical associations between VH, measures of dissociation, and trauma particularly (though not exclusively) childhood sexual abuse. There are 2 main conclusions from this review. First, we argue that available evidence suggests that VH experiences, including those in the context of psychotic disorders, can be most appropriately understood as dissociated or disowned components of the self (or self-other relationships) that result from trauma, loss, or other interpersonal stressors. Second, we provide a rationale for clinicians to use psychotherapeutic methods for integrating life events as precipitating and/or maintaining factors for distressing voices. Potential mechanisms for the relationship between trauma, dissociation, VH, and clinical diagnosis are described, including the relevance of literature from the field of attachment in providing a diathesis for dissociation. Suggestions for future research are also discussed.     

Sleep deprivation and stressors: Evidence for elevated negative affect in response to mild stressors when sleep deprived

Stress often co-occurs with inadequate sleep duration, and both are believed to impact mood and emotion. It is not yet known whether inadequate sleep simply increases the intensity of subsequent stress responses or interacts with stressors in more complicated ways. To address this issue, we investigated the effects of one night of total sleep deprivation on subjective stress and mood in response to low-stress and high-stress cognitive testing conditions in healthy adult volunteers in two separate experiments (total N = 53). Sleep was manipulated in a controlled, laboratory setting and stressor intensity was manipulated by changing difficulty of cognitive tasks, time pressure, and feedback about performance. Sleep-deprived participants reported greater subjective stress, anxiety, and anger than rested controls following exposure to the low-stressor condition, but not in response to the high-stressor condition, which elevated negative mood and stress about equally for both sleep conditions. These results suggest that sleep deprivation lowers the psychological threshold for the perception of stress from cognitive demands but does not selectively increase the magnitude of negative affect in response to high-stress performance demands.

Emotional engagement in the context of development and spirituality research

An awareness of spirituality and religion is increasingly being integrated within development theory and practice in order to recognise the way that many people approach community development. There are significant implications for researchers and their methodological practice that arise in paying attention to this area of development studies, particularly with regard to spiritual aspects of emotional engagement for researchers. This paper explores some of those implications from an analysis of my participatory research into geographies of development and spirituality. Two community groups with self-identified Christian spiritualities took part: a Melanesian settlement in Fiji and a women’s church-based group in rural Tanzania. I argue that emotional engagement and spiritual engagement are implicitly connected and demonstrate how attention to emotional knowledge provides valuable insight within this area of research. In particular, I illustrate how a relational approach to emotional knowledge, inspired by the philosophic and psychoanalytic work of Luce Irigaray, is particularly suited to approaching human and spiritual relationships and resonates with key concerns within participatory and community development. Paying particular attention to the concept of fidelity and the spatiality of subjectivity within her work, this paper illustrates the challenge from Luce Irigaray’s work regarding the relational framing of emotional knowledge and the transformational potential implicit within all research relationships.     

Identity Shift in Computer-Mediated Environments

The present study uses a public commitment framework to examine how computer-mediated self-presentations can alter identities. Participants were asked to present with one of two traits, extroversion or introversion, in public or private computer-mediated communication. Public presentations were online, whereas private presentations took place in a text document. Only participants that presented themselves publicly internalized the trait presentation, suggesting that identity shift took place. Public self-presentations also contained more certain and definite forms of language than private self-presentations, suggesting that audiences evoke a more committed form of self-presentation. The findings in this research have important implications for the self-construction of identity online, particularly for individuals that use the Internet as a tool for public self-presentation, such as dating sites, social network sites, or blogs. Also, the findings highlight opportunities for theoretical development on identity construction as a function of computer-mediated communication.     

The influence of partial‐match cues on event‐based prospective memory

In event‐based prospective memory tasks people form an intention to respond when an environmental cue signals that conditions are appropriate to fulfil an intended activity. In the ongoing activity the authors embedded partial‐match cues that only partially, but not completely, satisfied the conditions required to make a prospective response. The consequence of encountering these partial‐match cues was to increase responses to appropriate prospective memory cues encountered later. This outcome occurred both with semantic and orthographic cues, but only the former led to longer processing latencies of the partial‐match cues. This asymmetry suggests that partial‐match cues may not need to be processed consciously in order to benefit event‐based prospective memory. A parametric manipulation of the number of partial‐match cues resulted in numerically but not statistically better prospective memory. Consequently, partial‐match cues may function as overt reminders of the intention to respond or they may serve to engage participants in self‐initiated remindings of the intention.     

Quantification of Tactile Cueing for Enhanced Target Search Capacity

Soldiers on today's battlefield find themselves monitoring a host of displays in both vehicles and command centers, with personal-mounted displays looming in the near future. Such display proliferation makes the task of managing limited visual attention while searching for information extremely demanding and the potential for critical information loss due to visual demand overload. Cueing has traditionally provided a performance advantage in search tasks, with the current experiment exploring whether and how a specific tactile display format could guide visual attention. In particular, the use of the tactile cues decreased search response time by more than 30%. This was not a trade of speed for accuracy because the frequency of missed signals themselves was also reduced by approximately 70%, and false positives were suppressed by the addition of the tactile cue by over 50%. These findings represent useful foundational outcomes against which to compare other forms of sensory cueing.     

Interpersonal sensitivity, status, and stereotype accuracy

A classic question in social and organizational psychology is whether low-status persons are more accurate in the perception of their high-status partners than the latter are in their perception of their subordinates. In a series of studies, Snodgrass (1985, 1992) tested this idea. She found that subordinates were more accurate at judging how their bosses viewed them than bosses were at judging how their subordinates viewed them, but that bosses were more accurate at judging how subordinates viewed themselves than subordinates were at judging how bosses viewed themselves. We believe, however, that these results were obscured by stereotype accuracy. Using previously collected data, we found that stereotype accuracy does lead to the pattern previously observed by Snodgrass. We also discovered that when we controlled for stereotype accuracy, subordinates' perceptions were generally more accurate than those of their bosses, which supports Snodgrass's original hypothesis.
