Are delusional contents replayed during dreams?

The relationship between dream content and waking life experiences remains difficult to decipher. However, some neurobiological findings suggest that dreaming can, at least in part, be considered epiphenomenal to ongoing memory consolidation processes in sleep. Both abnormalities in sleep architecture and impairment in memory consolidation mechanisms are thought to be involved in the development of psychosis. The objective of this study was to assess the continuity between delusional contents and dreams in acutely psychotic patients. Ten patients with a single fixed and recurring delusional content were asked to report their dreams during an acute psychotic break. Sixteen judges with four different levels of acquaintance to the specific content of the patients’ delusions were asked to group the dreams, expecting that fragments of the delusional thought would guide the task. A mathematical index (f, t) was developed in order to compare correct groupings between the four groups of judges. Most judges grouped the dreams slightly above chance level and no relevant differences could be found between the four groups [F(3, 12) = 1.297; p = n.s.]. Scoring of dreams for specific delusional themes suggested a continuity in terms of dream and waking mentation for two contents (Grandiosity and Religion). These findings seem to suggest that at least some delusional contents recur within patients’ dreams. Future studies will need to determine whether such continuity reflects ongoing consolidation processes that are relevant to current theories of delusion formation and stabilization.     

Projective Tests in Vocational Counseling

In Switzerland, the role of projective techniques in vocational counseling is currently under debate. The author of a recent book on the Zulliger-test — a three card, Rorschach-type instrument — claims to have identified a number of syndromes that reflect vocationally relevant personality characteristics. His results are criticized on methodological grounds, and an alternative approach is proposed that emphasizes the expressive and essentially idiographic nature of projective test records. Their main contribution is to permit a better understanding of client motivations and attitudes, resulting in a more effective counseling interaction. Accordingly, these tests should be validated against attitudinal criteria and measures of counseling progress rather than long-term vocational behavior and success on the job.     

Believing in a Positive Future as a Form of Stigma Resistance: Narratives of Denied Expungement-Seekers

ABSTRACT

A large body of work documents how people contest and refute stigmatized definitions of themselves. Yet, research that examines the role of emotion displays in stigma resistance remains sparse. To begin to fill this gap, I analyze follow-up interview data with 17 people who, because of their past felony convictions, were deemed ineligible for expungement, a court-ordered destruction of the criminal record history. Overall, participants seized on the interview setting to challenge stigmatizing definitions of themselves. There were two key ways in which this occurred. First, participants offered optimistic accounts of their future well-being. These hopeful narratives suggested that, although they were aware of how people with criminal records are devalued, they did not accept a view of themselves as damaged. Second, participants drew on emotion displays of anger with the criminal justice system to underscore that they were not deserving of the discrimination they faced. Implications for research on the sociology of stigma and emotions are discussed.     

The Home-Based Occupational Therapy Intervention in the Alzheimer's Disease Multiple Intervention Trial (ADMIT)

There is no way to prevent functional declines related to Alzheimer's Disease (AD). The use of occupational therapy (OT) has been shown to be successful in managing some aspects of AD. We added home-based OT to evidence-based best practice for AD with the aim of delaying functional decline in people with AD. OT was delivered in the home to a caregiver dyad including the person with AD and her/his caregiver. This article describes the OT intervention for the AD Multiple Intervention Trial, a parallel randomized controlled trial. We include baseline data on the 180 caregiver dyads.     

Inter-individual variability of forces and modular muscle coordination in cycling: A study on untrained subjects

The aim of this study was to investigate the muscle coordination underlying pedaling in untrained subjects by using the muscle synergies paradigm, and to connect it with the inter-individual variability of EMG patterns and applied forces. Nine subjects performed a pedaling exercise on a cycle-simulator. Applied forces were recorded by means of instrumented pedals able to measure two force components. EMG signals were recorded from eight muscles of the dominant leg, and Nonnegative Matrix Factorization was applied to extract muscle synergy vectors W and time-varying activation coefficients H. Inter-individual variability was assessed for EMG patterns, force profiles, and H. Four modules were sufficient to reconstruct the muscle activation repertoire for all the subjects (variance accounted for >90% for each muscle). These modules were found to be highly similar between subjects in terms of W (mean r = .89), while most of the variability in force profiles and EMG patterns was reflected, in the muscle synergy structure, in the variability of H. These four modules have a functional interpretation when related to force distribution along the pedaling cycle, and the structure of W is shared with that present in human walking, suggesting the existence of a modular motor control in humans.     

Development of Prospective Memory: Tasks Based on the Prefrontal-Lobe Model

This study investigated the development of prospective memory using tasks based on the prefrontal-lobe model. Three groups each of 30 children, adolescents, and young adults were compared on prospective-memory performance using ongoing tasks with two levels of cognitive demand (low and high), and two levels of importance (unstressed and stressed) of remembering prospective cues. The Self-Ordered Pointing Task (SOPT), Stroop Color Word Interference Test, and Tower of London were also used to assess relationships between prospective memory and prefrontal-lobe functions. The children remembered fewer prospective cues than either the adolescents or adults, but the adolescents and adults remembered equally well. This trend increased significantly as the cognitive demand of the ongoing tasks increased. However, stressing or not stressing the importance of remembering made no difference to prospective-memory performance. Performance on the SOPT and Stroop Colour Word Interference predicted performance on the high- but not on the low-demand condition. These findings implicate the maturation of the brain's prefrontal region in the development of prospective memory.     

Posture affects emotional responses: A Head Down Bed Rest and ERP study

Body posture, mainly represented by horizontal bed rest, has been found to be associated with cortical inhibition, altered perceptual and cognitive processing. In the present research, the influence of Head Down Bed Rest (HDBR) – a condition also termed simulated microgravity – on emotional responses has been studied. Twenty-two male subjects were randomly assigned to either Sitting Control or HDBR group. After 3-h, subjects attended to a passive viewing emotional task in which 75 IAPS slides, divided into 25 pleasant, 25 neutral and 25 unpleasant, were presented in random order for 6 s each, while EEG was recorded from F7, F8 and Pz locations. Results showed in Sitting Controls the expected greater P300 and Late Positive Potential (LPP) to pleasant and unpleasant compared with neutral slides, an effect which indicates greater processing of emotional arousing stimuli. The HDBR group showed smaller non-significant differences among all emotional conditions in both ERP components. Arousal and valence subjective evaluations, typically less sensitive to experimental manipulation, did not differentiate groups. The observed ability of HDBR to inhibit cortical emotional responses raises an important issue on the risk that astronauts underestimate a dangerous/threatening situation or that long-term bedridden inpatients develop depressive symptoms.     

Deeper attentional masking by lateral objects in children with autism

Autism spectrum disorder (ASD) is often associated with a detail-oriented perception and overselective attention in visual tasks, such as visual search and crowding. These results were obtained manipulating exclusively the spatial properties of the stimuli: few is known about the spatio-temporal dynamics of visual processing in ASD. In this study we employed an attentional masking (AM) paradigm comparing children with ASD and IQ-matched typically developing (TD) controls. The AM effect refers to an impaired identification of a target followed by a competitive masking object at different proximities in space and time. We found that ASD and TD groups did not differ in the AM effect provoked by the competitive object displayed in the same position of the target. In contrast, children with ASD showed a deeper and prolonged interference than the TD group when the masking object was displayed in the lateral position. These psychophysical results suggest that the inefficient attentional selection in ASD depends on the spatio-temporal interaction between competitive visual objects. These evidence are discussed in the light of the ASD altered neural connectivity hypothesis and the reentrant theory of perception.     

Differential Attention as a Mechanism of Change in Parent–Child Interaction Therapy: Support from Time-Series Analysis

Although many interventions address children’s externalizing behavior problems, negative treatment outcomes remain common. Reasons for success or failure are frequently unclear, due in part to a lack of research identifying treatment change mechanisms. The current study evaluated differential attention as a mechanism of change in Parent–Child Interaction Therapy (PCIT), a treatment for children with externalizing problems. Using sequential coding and time-series analysis, we examined parent–child interactions across treatment for three families. Contrary to hypotheses, child prosocial behaviors and parent skill use held steady or decreased across coaching periods, with the exception of one family, where the parent’s skill use increased during coaching. Partial support was found for the hypothesis that parent differential attention would predict child prosocial behavior in the next minute. These results provide support for differential attention as a mechanism of change, but also demonstrate that this factor is not the only such mechanism.     

Predictors of Smoking Status After Eight Years: The Interaction of Stages of Change and Addiction Variables

Abstract

With a smoking rate of 30% of the population Switzerland has one of the highest rates of all industrialised countries. Changes in smoking status over eight years are examined by analysing the course of non-smokers, former smokers and current smokers between 1987 and 1995. Stages of change and addiction variables, as well as their interaction, are analysed for 1987 as predictors of smoking status in 1995.A sample of 953 non-smokers and former and current smokers was interviewed in 1987 and followed up in 1995. Between 1987 and 1995 every fifth non-smoker (20.9%) began smoking. The higher one is in the stage hierarchy the higher the probability of forward than of backward movement. Within the stages of change the likelihood of cessation is moderated by addiction variables. Thus, in the case of contemplating smokers in 1987, the more cigarettes they smoked daily at that time the less likely they were to be former smokers by 1995, but for preparating smokers who had already made an attempt to quit the converse holds - the more they smoked in 1987, the more likely they were to be non-smokers eight years later. The same holds for former smokers in 1987: former moderate smokers then were more likely to relapse than former heavy smokers. The implications for prevention and intervention are discussed.
