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.

What happens before and after acute enactments? An exercise in clinical validation and the broadening of hypotheses

This paper seeks to validate clinical facts and theoretical hypotheses that have been discussed before and that address configurations involving chronic and acute enactments. Its validation process compares clinical material from psychoanalytic work in different psychoanalytic cultures - work from South America-Uruguay (Yardino), Europe-Spain (Sapisochin), South Africa (Ivey), Europe-UK (Bateman). It documents clinical facts described in four articles and confirms that during chronic enactments the analytic dyad gets caught up in a dual relationship that veils and congeals the triangular situation because acknowledging it would be traumatic. The lack of triangular space impedes the formation of symbols as well as dreaming and creates non-dreams-for-two. During chronic enactments analysts use their implicit alpha-function to assemble traumatic areas. These areas emerge as a mix of discharges and non-dreams that are dreamed through acute enactments. Acute enactments occur when chronic enactments dissolve and patients experience an abrupt contact with reality. The attenuated trauma is then dreamed alive. The linking of new symbols develops a network of symbolic thought and creates dreams-for-two and broadens the patient's mental universe. The validation process has deepened our vision concerning clinical facts, especially in relation to: (1) the wavering between acute and chronic enactments, (2) analysts' inhibitions and feelings of guilt, and (3) the influence of analysts' personalities on the configurations they describe. These theoretical hypotheses have been confirmed and broadened not only in relation to the vicissitudes of dream work in traumatic areas, but also in relation to defenses such as thin or thick skin, and in relation to listening in countertransferential detours.     

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.     

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.     

Partial knowledge in a tip-of-the-tongue state about two- and three-word proper names

Participants in this study attempted to name 44 famous people in response to reading biographical information about them. Half of the celebrities had names that contained two words (e.g., Gwyneth Paltrow and Sean Penn), and half of them had names containing three words (e.g., Catherine Zeta Jones and Billy Bob Thornton). Half of the names had previously been judged to be of high familiarity (e.g., Gwyneth Paltrow), and half were of lower familiarity (e.g., Billy Bob Thornton). The results showed that when in a tip-of-the-tongue (TOT) state, the participants were able to estimate at above-chance rates whether a celebrity’s name comprised two or three words. Accurate information about the number of words was not available to the participants unless they were in a TOT state or had already named the person. Attempts to identify celebrities whose name had three elements were associated with an increased number of TOTs, relative to celebrities whose name had two units, but there was no difference in the number of don’t know responses for names containing two or three words. Calculations based on Gollan and Brown (2006) suggested that having three names impaired the phonological but not the semantic stage of lexical retrieval, whereas low familiarity impaired both semantic and phonological retrieval stages.     

An examination of the relationships among emotion management,interpersonal hassles,and depressive symptomatology

This study extended previous research by testing three models predicting depressive symptoms from emotion management (EM) and interpersonal hassles in a sample with a wide range of depression scores. Adults (n = 218) from sources including a depression internet site completed measures of interpersonal hassles, depression, and three aspects of EM (attention to, clarity of, and repair of emotions). Regression analyses supported a model in which lower clarity and repair scores and greater frequency of interpersonal hassles each contributed directly to depression scores. While lower attention to emotions was associated with fewer interpersonal hassles, it did not correlate significantly with depression scores. Moderation analyses did not support a model of EM components acting on depression by buffering effects of interpersonal hassles. A model of depression and hassles predicting EM difficulties was also considered; when both hassles and depression scores were entered to predict EM, only depressive symptoms uniquely predicted clarity and repair.     

Examining Current Conceptualizations of Psychopathology With the MMPI–2/MMPI–2–RF Restructured Clinical Scales: Preliminary Findings From a Cross-Cultural Study

Watson (2005 Watson, D. (2005). Rethinking the mood and anxiety disorders: A quantitative hierarchical model for DSM–V. Journal of Abnormal Psychology, 114, 522–536.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]) proposed a hierarchical reorganization of the underlying structure of emotional disorders. This study cross-culturally evaluated Watson's (2005) structure of mood and anxiety disorders, using mainly dichotomous criteria, and explored the placement of obsessive–compulsive disorder (OCD) in this model. It also tested Sellbom, Ben-Porath, and Bagby's (2008) proposed elaboration of the 2-factor model (positive and negative activation) that incorporates a higher order dimension of demoralization. One hundred men and 133 women from psychiatric settings in Israel completed the Minnesota Multiphasic Personality Inventory–2 (Butcher et al., 2001 Butcher, J. N., Graham, J. R., Ben-Porath, Y. S., Tellegen, A., Dahlstrom, W. G., &; Kaemmer, B. (2001). Minnesota Multiphasic Personality Inventory–2 (MMPI–2): Manual for administration, scoring and interpretation (Rev. ed.). Minneapolis: University of Minnesota Press.[Crossref] , [Google Scholar]) and the Maudsley Obsessional–Compulsive Inventory (Hodgson &; Rachman, 1977 Hodgson, R. J., &; Rachman, S. (1977). Obsessive–compulsive complaints. Behaviour Research and Therapy, 15, 389–395.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). They were interviewed using the Mini International Neuropsychiatric Interview (Sheehan et al., 1998 Sheehan, D. V., Lecrubier, Y., Sheehan, K. H., Amorim, P., Janavs, J., &; Weiller, E. (1998). The Mini-International Neuropsychiatric Interview (M.I.N.I.): The development and validation of a structured diagnostic psychiatric interview for DSM–IV and ICD–10. Journal of Clinical Psychiatry, 59, 22–33.[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Confirmatory factor analyses replicated Watson's structure for women but not for men. Mixed results were obtained regarding OCD's location in the model. Findings among women support the applicability of Watson's (2005) model across a variety of assessment modalities, as well as in a different language and for diversified cultural backgrounds. This conclusion, however, should be tempered in consideration of the results among men. Findings also provide evidence of the importance of demoralization in mood and anxiety disorders.     

Body Dissatisfaction, Dating, and Importance of Thinness to Attractiveness in Adolescent Girls

The primary aim of this study was to test a multivariate model of predictors of body dissatisfaction in adolescent girls in which psychological variables, beliefs about the importance of popularity with boys, and beliefs about the importance of thinness to attractiveness and dating were included. We also aimed to explore boys' perceptions of the importance of thinness for attractiveness. Grade 10 girls (n = 573) and boys (n = 145) completed questionnaires. Path analysis provided partial support for the model proposed. Dating did not predict body dissatisfaction, but a relationship between importance of popularity with boys and body dissatisfaction was fully mediated by the belief that boys see thinness as important in rating girls' attractiveness. Although girls underestimated the body size that is attractive to boys, over 85% of boys reported a girl's slimness influenced her attractiveness. Dating was not correlated with body mass index.     

Decoding overlapping memories in the medial temporal lobes using high-resolution fMRI

The hippocampus is proposed to process overlapping episodes as discrete memory traces, although direct evidence for this in human episodic memory is scarce. Using green-screen technology we created four highly overlapping movies of everyday events. Participants were scanned using high-resolution fMRI while recalling the movies. Multivariate pattern analysis revealed that the hippocampus supported distinct representations of each memory, while neighboring regions did not, demonstrating that the human hippocampus maintains unique pattern-separated memory traces even when memories are highly overlapping. The hippocampus also contained representations of spatial contexts that were shared across different memories, consistent with a specialized role in processing space.
