Cognitive control in belief‐laden reasoning during conclusion processing: An ERP study

Belief bias is the tendency to accept conclusions that are compatible with existing beliefs more frequently than those that contradict beliefs. It is one of the most replicated behavioral findings in the reasoning literature. Recently, neuroimaging studies using functional magnetic resonance imaging (fMRI) and event‐related potentials (ERPs) have provided a new perspective and have demonstrated neural correlates of belief bias that have been viewed as supportive of dual‐process theories of belief bias. However, fMRI studies have tended to focus on conclusion processing, while ERPs studies have been concerned with the processing of premises. In the present research, the electrophysiological correlates of cognitive control were studied among 12 subjects using high‐density ERPs. The analysis was focused on the conclusion presentation phase and was limited to normatively sanctioned responses to valid–believable and valid–unbelievable problems. Results showed that when participants gave normatively sanctioned responses to problems where belief and logic conflicted, a more positive ERP deflection was elicited than for normatively sanctioned responses to nonconflict problems. This was observed from ?400 to ?200 ms prior to the correct response being given. The positive component is argued to be analogous to the late positive component (LPC) involved in cognitive control processes. This is consistent with the inhibition of empirically anomalous information when conclusions are unbelievable. These data are important in elucidating the neural correlates of belief bias by providing evidence for electrophysiological correlates of conflict resolution during conclusion processing. Moreover, they are supportive of dual‐process theories of belief bias that propose conflict detection and resolution processes as central to the explanation of belief bias.     

Grief in two guises: ‘Mourning and melancholia’ revisited

¹ 1. A version of this paper was given at the Institute of Psychoanalysis Conference: ‘Mourning and Melancholia through the Life Cycle’, London, 1998. This paper is a re-reading of Freud’s classic paper. The themes of mourning and melancholia are viewed in relation to children and adolescents with illustrations from case histories. Mourning is interpreted in a broader sense: not only as grief (both expectable and traumatic) but as a response to the developmental process itself as phases of childhood are shed and an emerging newer identity is assumed. The author argues that Freud’s paper left the way open to make a number of further distinctions of the processes involved within melancholia.     

Emotional turbulence during the ending of psychotherapy with an anorexic adolescent

In this paper I reflect on the phase of the analytic process which precedes the termination of a psychoanalysis and describe my work with an adolescent girl. Adolescents with serious eating disorders relive in a particularly violent way, in the final phase of their analysis, the catastrophic anxiety of separation and the fear of annihilation connected with this. The perception of the final date, felt to be irrevocable, reactivates in these patients the psychotic part of their personality, which tries through a phantasy of omnipotent possession (expressed through pathological projective identification) to obscure the reality of separateness and loss. It is useful with these patients to set a date for ending at least a year in advance to enable the working through of these psychotic anxieties. Clinical material illustrates how in the final year of treatment all phases of the analytic process are relived in a violent way, and how this emotional turbulence manifests id as a battle between omnipotent phantasy and an increasing insight into psychic reality.     

The buffering effect of awe on negative affect towards lost possessions*

Abstract

Although the positive emotion of awe is of growing interest, past research has not directly examined its buffering effect in negative circumstances. As awe has been theoretically linked to experiences of vastness and spirituality, the present study proposes that awe helps individuals alleviate their negative affect, in the context of possession loss. Study 1 manipulated awe and examined participants’ responses in an imagined situation in which they lost a cherished possession. Study 2 manipulated awe and happiness and compared their effects on participants’ response to an actual loss in the form of points obtained and deducted during a laboratory task. In Study 3, daily experiences of awe, other positive emotions, and affect in response to actual loss, were measured using event sampling. In all studies, awe predicted lower negative affect towards loss of possessions. Implications of the function of awe in coping with loss and other future directions are discussed.     

Resource loss,religiousness, health,and posttraumatic growth following Hurricane Katrina

This study examined associations among resource loss, religiousness (including general religiousness, religious comfort, and religious strain), posttraumatic growth (PTG), and physical and mental health among a sample of Mississippi university students soon after Hurricane Katrina hit the Gulf coast in 2005. Resource loss was negatively associated with health, but positively associated with PTG. Religious comfort was associated with positive outcomes, and religious strain was associated with negative outcomes. Religious comfort buffered the negative effects of resource loss on emotional health. Ancillary analyses indicated that associations between resource loss and health were mediated by religious strain. Implications of this research are described for mental health practitioners engaged in disaster recovery work.     

The ambiguity of loss affects some,but not all autobiographical memories: redemption and contamination,agency and communion

ABSTRACT

Compared with clear-cut loss by death, ambiguous loss is defined as a loss that is not definite because the person is missing or mentally absent but physically present (e.g., through Alzheimer's disease). We expected the ambiguity of loss to show in psychologically more compromised loss memories and self-defining memories, but not in autobiographical memories in general. Thirty Chinese adults who had lost a parent through death, thirty whose parent had gone missing, and thirty who cared for a demented parent narrated their loss experiences and memories of sad and turning-point events as well as self-defining memories. Individuals with ambiguous loss narrated the loss and a self-defining memory with more contamination and fewer redemption sequences, and only the loss memory with fewer themes of agency and communion than individuals with definite loss, but not in memories of sad and turning point events. Effects of ambiguity of loss were independent of prolonged grief, which in turn independently predicted some of these effects. Thus the ambiguous quality of loss predicts effects on loss memories and self-defining memories independently of psychiatric symptoms.     

Computer-assisted dieting: Effects of a randomised controlled intervention

In this pilot study, the effects of two computer-assisted dieting (CAD) interventions on weight loss and blood chemistry were examined among overweight and obese adults. Participants (91 community members, average age 42.6 years) were randomly assigned to CAD-only (a single-session introduction and provision of a dieting software, n = 30), CAD plus an additional four-session self-management group training (CAD+G, n = 31) and a waitlist control group whose members were randomised into the two interventions at the 3-month follow-up (n = 30). A three (group)-by-two (time) repeated measures ANOVA revealed no significant group by time interaction during the initial 3-month period. However, the two intervention groups combined showed a significant, though moderate weight loss relative to the control group. Further, although a general improvement was found with regard to the lipid panel results during the first 3 months of the trial, the treatment by time interaction was not significant. A comparison of the developments in the two intervention groups during the 3- to 6-month follow-up time period revealed a tendency towards greater weight regain in the CAD-only condition. The evidence suggests that CAD supports initial weight loss; however, additional self-management training might be necessary to support maintenance.     

Path analysis of exercise treatment-induced changes in psychological factors leading to weight loss

Physical activity may affect weight loss largely through psychological pathways associated with eating changes, especially in obese individuals whose caloric expenditure through exercise is typically small. Direct testing of this is, however, lacking. Previously sedentary adults (N?=?114; 77% female; M _age?=?43.3 years), with a minimum body mass index (BMI) of 35?kg/m² (M _BMI?=?42.0?kg/m²), participated in a 24-week treatment of cognitive-behavioural exercise support and nutrition information. A path model based on tenets of social cognitive and self-efficacy theory was constructed. It was expected that improvements in self-efficacy, physical self-concept, body satisfaction and mood associated with the exercise treatment would predict changes in self-regulation and increased physical activity. It was also hypothesised that improvements in self-efficacy and self-regulation for appropriate eating would transfer from these relationships and predict weight loss. After three theoretically viable paths were added based on modification indices, structural equation modelling indicated a good fit with the data, χ ²(16)?=?20.53, p?=?0.20; RMSEA?=?0.05; SRMR?=?0.06; CFI?=?0.97; TLI?=?0.95. Associations of psychological effects linked to exercise programme participation with predictors of appropriate eating and weight loss were found, and may inform theory, research and treatments.     

Identifying predictor variables of weight loss outcome: Implications for a stepped program and weight management

Abstract

Four variables were identified that predicted outcome for the minimal and moderate intensity weight control programs presented in sequence. Predictive models for pounds lost and percentage overweight lost were computed for both programs and follow-up and accounted for 33% to 62% of the variance. The predictor variable that contributed to the two programs and follow-up was success in losing weight previously. Greater rate of weight loss in the first five weeks contributed to the model for the minimal intensity program and for follow-up and total number of calories expended in nonroutine physical activity added to the model for the minimal intensity program. Marital dissatisfaction of subjects was a predictor for the moderate intensity program and follow-up. The findings have utility for a stepped program for weight and provide confirmation of variables noted as predictors in prior research. This study may help in the quest to identify consistent predictors of weight loss success.     

Coping strategies used by middle-aged males with noise-induced hearing loss,with and without tinnitus

Abstract

The aim of this study was to examine the relationship between general coping strategies and specific communication strategies, adopted by males with noise-induced hearing loss (NIHL) in order to deal with stressful events and demanding auditory situations. The sample included 72 males with NIHL; 22 without tinnitus, 26 with mild tinnitus, and 24 with severe tinnitus. The following variables were measured: “active coping” “escape coping” and “passive acceptance” (general coping strategies), and “maladaptive behaviours”, “verbal strategies” and “nonverbal strategies” (specific communication strategies). The results showed that males without tinnitus or with mild tinnitus combined “active coping” and “passive acceptance”, whereas males with severe tinnitus supplemented these strategies with “escape coping”. The relationship between general coping and specific communication strategies was weak, although giving a significant correlation between “escape coping” and “maladaptive behaviours”. The results indicate that the hypothesis that a person's general pattern of coping has influence on his/her ability to cope effectively with a hearing impairment can not be supported. Further research should concentrate on the contribution of personality factors as well as environmental factors to the variance in coping with NIHL and tinnitus.
