Being confident without seeing: What subjective measures of visual consciousness are about

Can observers be confident about the accuracy of a discrimination response without a visual experience of the stimulus? In a series of five experiments, observers performed a masked orientation discrimination task, a masked shape discrimination task, or a random-dot motion discrimination task, followed by two subjective ratings after each trial, in which participants reported either their visual experience of the stimulus or their confidence in being correct. We observed that the threshold for ratings of the perception of the stimulus was above the threshold for ratings of a decision, that decision ratings outperformed stimulus ratings in predicting trial accuracy, and that different decision-related scales were more strongly associated with other decision-related scales than with ratings of stimulus clarity. We propose a taxonomy of subjective measures of consciousness that differentiates between subjective measures relating to the percept of the stimulus and measures relating to a discrimination decision and discuss the relation to type II blindsight.     

An Exploratory Evaluation of the Family Meal Intervention for Adolescent Anorexia Nervosa

Although weight restoration is a crucial factor in the recovery of anorexia nervosa (AN), there is scarce evidence regarding which components of treatment promote it. In this paper, the author reports on an effort to utilize research methods in her own practice, with the goal of evaluating if the family meal intervention (FMI) had a positive effect on increasing weight gain or on improving other general outcome measures. Twenty‐three AN adolescents aged 12–20 years were randomly assigned to two forms of outpatient family therapy (with [FTFM] and without [FT]) using the FMI, and treated for a 6‐month duration. Their outcome was compared at the end of treatment (EOT) and at a 6‐month posttreatment follow‐up (FU). The main outcome measure was weight recovery; secondary outcome measures were the Morgan Russell Global Assessment Schedule (MRHAS), amenorrhea, general psychological symptoms, and eating disorder symptoms. The majority of the patients in both groups improved significantly at EOT, and these changes were sustained through FU. Given its primarily clinical nature, findings of this investigation project preclude any conclusion. Although the FMI did not appear to convey specific benefits in causing weight gain, clinical observation suggests the value of a flexible stance in implementation of the FMI for the severely undernourished patient with greater psychopathology.     

Relation Between Outcomes on a Continuous Performance Test and ADHD Symptoms Over Time

This study examined the relationship between the developmental trajectories of neuropsychological functioning and ADHD symptomatology in a longitudinal sample of children ages 9 to 14. Participants and measures were derived from the Multimodal Treatment Study for ADHD including 534MTA participants and 254 normal controls. Despite improvement over time, MTA participants continued to receive higher ratings of ADHD symptomatology and exhibit greater difficulties across the majority of neuropsychological outcomes. No relations were found between improvements in neuropsychological functioning and ADHD symptomatology over time. Findings provide support for the persistence of neuropsychological functioning and ADHD symptomatology. Findings did not support the hypothesized relation between improvements in frontally-mediated neuropsychological functioning and ADHD symptomatology possibly due to the brief 1-year lag and limited assessment battery. Findings are discussed in relation to neuropsychological development including recommendations for future research.     

Validation of the German Version of the Sexual Self-Esteem Inventory for Women and its Application in a Sample of Sexually and Physically Abused Women

Results regarding the association between global self-esteem and sexual behavior suggest the importance of a domain-specific construct—so-called sexual self-esteem (SSE). Prior studies suggested that SSE is malleable and found a negative impact of sexual abuse on SSE. In the present study, the German translation of the Sexual Self-Esteem Inventory-Short Form (SSEI-SF) by Zeanah and Schwarz (1996) was validated via an online survey with 557 women and then investigated in a clinical sample of women suffering from PTSD following sexual and physical abuse compared with healthy controls (n = 130). We examined differences in SSE depending on the type of abuse. Confirmatory factor analysis revealed adequate model fit, with acceptable-to-excellent reliability (α = .78–.94) and sound convergent and discriminant validity. As expected, SSEI-SF scores were significantly lower in the clinical sample than those in the healthy control group. Within the clinical sample, there were no significant differences in SSE between clients who had experienced sexual abuse and those who had experienced physical abuse, but a history of sexual abuse was significantly linked to lower SSE and SSE was related to both sexual behavior and sexual satisfaction. In conclusion, our study supports the validity and applicability of the German version of the SSEI-SF. Results regarding the differences in SSE between survivors of abuse and healthy controls contribute to the further understanding of female sexuality and have implications for treatment.     

Neuroscience in Pursuit of the Holy: Mysticism, the Brain, and Ultimate Reality

Eugene d'Aquili and Andrew B. Newberg's The Mystical Mind: Probing the Biology of Religious Experience presents a core theory regarding the neurophysical nature of mystical experience; extensions of this theory, focusing upon near-death experiences and the nature of religion itself; and buttressing arguments proposing that genetically based neurophysical "operators" within the brain compel human beings to think in certain ways. On the basis of this work, the authors pose a "metatheology," suggesting that certain brain operations may underlie all the religions of the world. The core theory, its extensions, and related arguments are discussed in turn, concluding with commentary on the authors' constructive theology.     

A comparison of linear and mixture models for discriminant analysis under nonnormality

Methods for discriminant analysis were compared with respect to classification accuracy under nonnormality through Monte Carlo simulation. The methods compared were linear discriminant analyses based both on raw scores and on ranks; linear logistic discrimination; and mixture discriminant analysis. Linear discriminant analysis and linear logistic discrimination were suboptimal in a number of scenarios with skewed predictors. Linear discriminant analysis based on ranks yielded the highest rates of classification accuracy in only a limited number of situations and did not produce a practically important advantage over competing methods. Mixture discriminant analysis, with a relatively small number of components in each group, attained relatively high rates of classification accuracy and was most useful for conditions in which skewed predictors had relatively small values of kurtosis.     

Executive functioning and psychological adjustment in children and youth with spina bifida

Children and adolescents with spina bifida are at risk for poor neuropsychological functioning and psychological outcomes. The relationship between executive functioning and psychological adjustment is an area worthy of investigation in this population. The current study assessed executive functioning and psychological outcomes in a group of children and adolescents with spina bifida (SBM) (n = 51) and nondisabled controls (n = 45). A mediation model was hypothesized, such that Metacognition, as measured by the Behavior Rating Inventory of Executive Function (BRIEF), mediated the relationship between group status (spina bifida versus nondisabled controls) and psychological outcomes. Results indicated that metacognitive skills fully explained the relationship between group and internalizing and depressive symptoms as reported by mothers. In particular, specific components of the BRIEF Metacognition composite were most responsible for this relationship, including Initiate, Working Memory, and Plan/Organize. The study limitations include its cross-sectional nature that precludes drawing conclusions about causality. The results have implications for treatment interventions for children and adolescents with spina bifida and typically developing individuals.     

Development and Practice of the Systems Paradigm in Argentina, Chile and Peru

The systems paradigm has been developing in the southern region of South America for more than three decades, albeit at different paces and with a variety of achievements as can be expected when describing the process of countries as diverse as Argentina, Chile and Peru. This article describes the circumstances and actions that have enabled the systemic approach to gain a legitimate place in the local psychotherapy field permeating family, marital/couple, and individual therapy. Moreover, the family/contextual perspective has attained a valued respectability in the family legal system as well as in community interventions. Overall, the community is aware of and at ease with this efficacious contextual approach. As in other parts of the world, the universities have joined the private entities in the training endeavor and the accreditation process is a complex goal with obstacles that have not yet been surmounted.
