Learning as a possible sign of non-reflective consciousness in persons with a diagnosis of vegetative state and pervasive motor impairment

A diagnosis of vegetative state represents a serious predicament, which basically precludes/minimizes rehabilitation perspectives. Reliability of the assessment approach in these situations is of paramount importance, but not easy to achieve. In recent studies, a learning assessment procedure has been suggested as a supplement in the diagnostic process and assessed with eight patients. The procedure involves an ABABCB sequence in which A represents baseline phases with no stimulation available, B intervention phases with stimuli delivered contingently on target responses, and C a control condition. This condition involves stimulation presented non-contingently. The patients’ ability to associate responding with environmental stimuli and thus increase such responding during the B phases, and reduce it during the A and C phases, may be considered a sign of learning. Learning might be viewed as representative of forms of concrete knowledge and presumably basic levels of consciousness. Preliminary results indicate that (a) signs of learning may appear in patients with a previous diagnosis of vegetative state and (b) the presence of those signs may require a revision of their diagnostic label and a reappraisal of their rehabilitation perspectives.     

Contextual fear conditioning predicts subsequent avoidance behaviour in a virtual reality environment

Avoidance behaviour is a crucial component of fear and is importantly involved in the maintenance of anxiety disorders. Presumably, fear conditioning leads to avoidance of the feared object or context. A virtual reality contextual fear conditioning paradigm was used to investigate the association between explicit conditioning effects and subsequent avoidance behaviour. Mild electric shocks were administered in one context (anxiety context), but never in a second context (safety context). Subsequent avoidance behaviour was assessed by asking participants to choose two out of three contexts (a neutral context was added) to visit again. Participants avoided the anxiety context, but did not prefer the safety over the neutral context. Participants with substantial conditioning effects, as reflected in differential valence, arousal and anxiety ratings, avoided the anxiety context but not the safety context. In sum, we demonstrated an association between context conditioning effects on an explicit level and later avoidance behaviour.     

Religion,Health, and Psychological Well-Being

This study compares the effects of religiosity on health and well-being, controlling for work and family. With 2006 GSS data, we assess the effects of religiosity on health and well-being, net of job satisfaction, marital happiness, and financial status. The results indicate that people who identify as religious tend to report better health and happiness, regardless of religious affiliation, religious activities, work and family, social support, or financial status. People with liberal religious beliefs tend to be healthier but less happy than people with fundamentalist beliefs. Future research should probe how religious identity and beliefs impact health and well-being.     

Seven-month-olds detect ordinal numerical relationships within temporal sequences

Previous evidence has shown that 11-month-olds represent ordinal relations between purely numerical values, whereas younger infants require a confluence of numerical and non-numerical cues. In this study, we show that when multiple featural cues (i.e., color and shape) are provided, 7-month-olds detect reversals in the ordinal direction of numerical sequences relying solely on number when non-numerical quantitative cues are controlled. These results provide evidence for the influence of featural information and multiple cue integration on infants’ proneness to detect ordinal numerical information.     

Assessment of emotional reactivity produced by exposure to virtual environments in patients with eating disorders.

The aim of this study was to assess the usefulness of virtual environments representing situations that are emotionally significant to subjects with eating disorders (ED). These environments may be applied with both evaluative and therapeutic aims and in simulation procedures to carry out a range of experimental studies. This paper is part of a wider research project analyzing the influence of the situation to which subjects are exposed on their performance on body image estimation tasks. Thirty female patients with eating disorders were exposed to six virtual environments: a living-room (neutral situation), a kitchen with high-calorie food, a kitchen with low-calorie food, a restaurant with high-calorie food, a restaurant with low-calorie food, and a swimming-pool. After exposure to each environment the STAI-S (a measurement of state anxiety) and the CDB (a measurement of depression) were administered to all subjects. The results show that virtual reality instruments are particularly useful for simulating everyday situations that may provoke emotional reactions such as anxiety and depression, in patients with ED. Virtual environments in which subjects are obliged to ingest high-calorie food provoke the highest levels of state anxiety and depression.     

The Couple's Grid: A Tool for Assessing Interpersonal Construction in Couples

In the study of human relationships, interest in interpersonal construction is increasing because of its implications for the quality of the couple's relationship. The processes involved in construing self and others may play a key role. However, a precise methodology to study those processes has not yet been developed. The aim of this article is to present a dyadic assessment tool, the couple's grid (CG), which is inspired from constructivist and systemic perspectives. Derived from Procter's (1985) family grid, the CG is similarly based on the repertory grid technique. The CG assesses perception of self and partner, and their ideals, and also the metaperception of the partner's view (e.g., “What does your partner think about you?”). These two levels of analysis provide measures of perceived similarity, commonality, and sociality. This article describes the development of CG as an assessment tool with a case illustration.     

Hegemonic Masculinity and Mental Health Among Older White Men in the U.S.: The Role of Health and Wealth Decline

Millions of men in the US experience substance abuse and impulse control disorders, which is well researched. Far fewer scholars have studied the millions of men that also experience depression (which is traditionally associated with women). Drawing upon literature on fragile masculinity and masculinity threat, we evaluate the role of endorsing hegemonic masculinity ideals (e.g., men should be strong, unemotional, and financially secure) in both internalizing (depression) and externalizing (anger) mental health problems, focusing on older White men aged 70–74 in the Wisconsin Longitudinal Survey (N?=?1,794). In addition to predicting mental health among older men according to their agreement with hegemonic masculinity ideals, we examine the impact of two potential threats to masculinity: health and wealth decline. We find that endorsement of hegemonic masculinity ideals is positively associated with externalizing and internalizing symptoms and that the association between hegemonic masculinity ideals and depressive symptoms is even stronger for men who perceive their health to be declining and those who have lost wealth. We conclude that endorsement of rigid hegemonic masculinity ideals negatively impacts older men’s mental health, especially when they experience challenges to their self-perception as strong, independent, and self-reliant. We provide suggestions as to how improving our understanding of the association between masculinity beliefs and mental health can inform clinical practice as well as public health and public policy.
