The psychotic personality: A psychoanalytic theory and its application in clinical practice

This paper presents and discusses aspects of Bion's theory of the psychotic personality. In particular, it focuses on the psychotic personality's attacks on the dependent and needy self. The paper considers how Bion's theory can be applied to understanding the schizophrenic patient. Examples are given to show its importance not only in analytic practice, but also within general psychiatry.     

Acculturative Distress Among Hispanics: The Role of Acculturation,Coping, and Intercultural Competence

Among 96 Hispanic adults, mostly recent immigrants responding in Spanish, intercultural competence contributed to variance in acculturative distress beyond that already accounted for by general coping, acculturation, and sociodemographic variables. Intercultural competence best predicted acculturative distress. Findings suggest that Hispanics with a low sense of intercultural and intracultural proficiency may experience increased stress. Entre 96 adultos hispanos, inmigrantes en su mayor parte recientes que responden en el español, la capacidad intercultural contribuida a la variación de asimilación penosa más allá que ha sido justificada por el enfrentamiento general, asimilación, y los variables sociodemograficos. La capacidad intercultural que mejor predijo la penosa asimilación. Los hallazgos sugieren que los hispanos con un sentido bajo de nivel de competencia intercultural y intracultural pueden sufrir de un nivel alto de estrés.     

Do Social Relationships Buffer the Effects of Widowhood? A Prospective Study of Adaptation to the Loss of a Spouse

The idea that strong social relationships can buffer the negative effects of stress on well‐being has received much attention in existing literature. However, previous studies have used less than ideal research designs to test this hypothesis, making it difficult to draw firm conclusions regarding the buffering effects of social support. In this study, we examined the buffering hypothesis in the context of reaction and adaptation to widowhood in three large longitudinal datasets. We tested whether social relationships moderated reaction and adaptation to widowhood in samples of people who experienced loss of a spouse from three longitudinal datasets of nationally representative samples from Germany (N = 1,195), Great Britain (N = 562), and Australia (N = 298). We found no evidence that social relationships established before widowhood buffered either reaction or adaptation to the death of one's spouse. Similarly, social relationships that were in place during the first year of widowhood did not help widows and widowers recover from this difficult event. Social relationships acquired prior to widowhood, or those available in early stages of widowhood, do not appear to explain individual differences in adaptation to loss.     

Distributive Justice for Others,Collective Angst,and Support for Exclusion of Immigrants

Harsh treatment of others can reflect an underlying motivation to view the world as fair and just and also a dispositional tendency to believe in justice. However, there is a critical need to refine and expand existing knowledge, not only to identify underlying psychological processes but also to better understand how justice may be implicated in support for exclusionary policies. Across two studies, we show that support for policies that restrict immigrants is exclusively associated with thoughts about fair outcomes for other people (distributive justice for others). In Study 1, Americans' dispositional tendency to believe in distributive justice for others was associated with greater support for a policy proposing to further restrict immigrant job seekers' capacity to gain employment in the United States. In Study 2, we experimentally primed thoughts about justice in a sample of U.S. police officers. Support for a policy that mandated stricter policing of illegal immigration was strongest among officers who first thought about fair outcomes for other people, relative to other unique justice primes. Across both studies, distributive justice for others was associated with greater collective angst—perceived threat towards the future existence of Americans. Moreover, collective angst mediated the link between distributive justice for others and support for restrictive policies. Overall, this research suggests that thoughts about distributive justice for others can especially diminish compassion towards immigrants and other underprivileged groups via support for exclusionary policies. In addition, merely thinking about distributive justice for others may be sufficient to amplify social callousness.     

Do Visually Salient Stimuli Reduce Children’s Risky Decisions?

Children tend to overestimate their physical abilities, and that tendency is related to risk for unintentional injury. This study tested whether or not children estimate their physical ability differently when exposed to stimuli that were highly visually salient due to fluorescent coloring. Sixty-nine 6-year-olds judged physical ability to complete laboratory-based physical tasks. Half judged ability using tasks that were painted black; the other half judged the same tasks, but the stimuli were striped black and fluorescent lime-green. Results suggest the two groups judged similarly, but children took longer to judge perceptually ambiguous tasks when those tasks were visually salient. In other words, visual salience increased decision-making time but not accuracy of judgment. These findings held true after controlling for demographic and temperament characteristics.     

Justifying Outcomes Versus Processes: Distributive and Procedural Justice Beliefs as Predictors of Positive and Negative Affectivity

System justifying beliefs can have adaptive consequences for individuals that include enhanced coping and decreased emotional distress. The present study examined whether individual differences in two kinds of system justifying beliefs uniquely predict dispositional affect. Participants from across the United States were recruited via internet to complete dispositional measures of procedural and distributive justice beliefs, and also brief measures of positive and negative affectivity. While belief in fair outcomes (distributive just world beliefs) was generally associated with greater positive affectivity, belief in fair processes (procedural just world beliefs) was modestly associated with decreased negative affectivity. In addition, positive and negative affectivity were predicted by interactions between procedural and distributive just world beliefs, with each accentuating the general emotional benefit provided by the other. Finally, an interactive effect of procedural just world beliefs and social class was obtained for positive affectivity, with greater positive affectivity occurring for disadvantaged (lower income) individuals who had strong procedural just world beliefs. In general, these results suggest the potential for unique and interactive relationships between particular system justifying beliefs and measures of emotion, especially among members of advantaged versus disadvantaged groups.     

Non-invasive estimation of local field potentials for neuroprosthesis control

Recent experiments have shown the possibility of using the brain electrical activity to directly control the movement of robots or prosthetic devices in real time. Such neuroprostheses can be invasive or non-invasive, depending on how the brain signals are recorded. In principle, invasive approaches will provide a more natural and flexible control of neuroprostheses, but their use in humans is debatable given the inherent medical risks. Non-invasive approaches mainly use scalp electroencephalogram (EEG) signals and their main disadvantage is that these signals represent the noisy spatiotemporal overlapping of activity arising from very diverse brain regions, i.e., a single scalp electrode picks up and mixes the temporal activity of myriads of neurons at very different brain areas. In order to combine the benefits of both approaches, we propose to rely on the non-invasive estimation of local field potentials (LFP) in the whole human brain from the scalp measured EEG data using a recently developed inverse solution (ELECTRA) to the EEG inverse problem. The goal of a linear inverse procedure is to de-convolve or un-mix the scalp signals attributing to each brain area its own temporal activity. To illustrate the advantage of this approach we compare, using an identical set of spectral features, classification of rapid voluntary finger self-tapping with left and right hands based on scalp EEG and non-invasively estimated LFP on two subjects using a different number of electrodes.

Adaptation and the Set-Point Model of Subjective Well-Being: Does Happiness Change After Major Life Events?

ABSTRACT— Hedonic adaptation refers to the process by which individuals return to baseline levels of happiness following a change in life circumstances. Dominant models of subjective well-being (SWB) suggest that people can adapt to almost any life event and that happiness levels fluctuate around a biologically determined set point that rarely changes. Recent evidence from large-scale panel studies challenges aspects of this conclusion. Although inborn factors certainly matter and some adaptation does occur, events such as divorce, death of a spouse, unemployment, and disability are associated with lasting changes in SWB. These recent studies also show that there are considerable individual differences in the extent to which people adapt. Thus, happiness levels do change, and adaptation is not inevitable.     

The relationship between self-reported received and perceived social support: A meta-analytic review

Social support is broad term encompassing a variety of constructs, including support perceptions (perceived support) and receipt of supportive behaviors (received support). Of these constructs, only perceived support has been regarded as consistently linked to health, and researchers have offered differing assessments of the strength of the received-perceived support relationship. An overall estimate of the received-perceived support relationship would clearly further the dialogue on the relationship between received and perceived support and thus assist in the theoretical development of the field. This study evaluated all available studies using the Inventory of Socially Supportive Behaviors (ISSB; Barrera, Sandler, & Ramsey, 1981, American Journal of Community Psychology, 9, 435–447) and any measure of perceived social support. Using effect sizes from 23 studies, we found an average correlation of r = .35, p < .001. Implications of this estimate for further development of models of social support as well as interventions to enhance social support are discussed.
