Parental death and absence in children presenting for mental health care

Of 61 youth (M age 11.2 yr.) seeking mental health care, almost 60% had experienced parental death or absence. 13 (21.3%) had experienced the death of a parent during the preceding 3 years.     

rTMS for PTSD: induced merciful oblivion or elimination of abnormal hypermnesia?

Neuroimaging studies and experimental data suggest that symptoms of posttraumatic stress disorder (PTSD) are associated with dysfunctions of neural circuits linking prefrontal cortex and the limbic system that have a role in autobiographic episodic memory. High-frequency repetitive transcranial magnetic stimulation (rTMS) of the right dorsolateral prefrontal cortex (DLPFC) has been suggested to be beneficial to patients with PTSD, transiently alleviating re-experiencing as well as avoidance reactions and associated anxiety symptoms. In healthy humans, converging evidence suggests that rTMS of the right DLPFC interferes with episodic memory retrieval. Hence, we hypothesize that daily applications of rTMS in PTSD patients may reduce access to the set of autobiographical stored events, that, if re-experienced, may cause the overt PTSD symptoms.     

Effects of team and organizational commitment – A longitudinal study

Retention management, i.e., keeping qualified employees, is a top priority for contemporary organizations. Commitment, and especially team commitment, can be the key to mastering this challenge. There is a lack of longitudinal research concerning the development and the direction of the effects of team commitment over time. In a longitudinal field-study design with three points of measurement, a total of 360 employees in 52 semi-autonomous industrial teams were surveyed over a period of three years. On the one hand, organizational commitment showed stronger effects on organization-related criteria (job satisfaction and intention to leave). These effects were consistent over the three points of measurement. Team commitment, on the other hand, affected team-related criteria (team performance and altruism). Longitudinal analyses confirmed the effects of organizational commitment on job satisfaction and intention to leave, and of team commitment on team performance and altruism. Moreover, these effects increased over time. Theoretical and practical implications of these findings are discussed.     

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.     

Assessing Male Batterers With the Personality Assessment Inventory

Despite the importance of the assessment of ego strength for appropriate assignment of clients for psychotherapy and/or rehabilitation, existing techniques have not fulfilled expectations. A method for assessing ego strength through the Rorschach Test independent of clinical criterion is proposed. In addition to certain variables of Klopfer's RPRS (M+, FM+, FC+ plus CF+), sharply preceived space responses are included. They constitute a highly intercorrelated global measure of ego strength and are also highly correlated to a relatively independent Rorschach variable of global ego efficiency, i.e. integrated whole responses. In accordance with prediction, non-controlled color responses as well as accuracy of form perception did not correlate in a non-clinical sample with either measure of ego strength.     

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.     

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.
