The influence of object-image velocity change on perceived heading in minimal environments

When human observers move forward and rotate their eyes, a complex pattern of light flows across the retina. This pattern is referred to as retinal flow. A model has been proposed to explain how humans perceive their direction of self-movement (or heading) from (1) static depth, (2) direction of image motion, and (3) whether image velocity undergoes acceleration or deceleration (Wang & Cutting, 1999). However, findings from past research in which sparse or minimalist stimuli were used have suggested that not all of the information to which participants are sensitive is captured within the scope of this model. In particular it has been suggested that the magnitude or size of image velocity change may be of significance beyond simply whether image velocity could be categorized as speeding up (i.e., accelerating) or slowing down (i.e., decelerating). In two experiments, the influence of this factor on heading judgments under minimal conditions was investigated. Evidence was found in support of the idea that the rate of image velocity change can influence judgments of the direction of self-movement in minimalist conditions.     

Belief in good luck and psychological well-being: the mediating role of optimism and irrational beliefs

The authors examined the relationship of belief in good luck with depression and anxiety within the context of a number of cognitive and personality variables used to explain depression and anxiety. Undergraduate students (46 men, 98 women) were administered measures of belief in good luck, depression, anxiety, optimism, neuroticism, attribution style, self-esteem, and irrational beliefs. The results showed that belief in good luck was significantly related to optimism and irrational beliefs. A number of models were tested to determine whether irrational beliefs or optimism mediated the relationship between belief in good luck and depression and anxiety. The findings suggested that negative relationships between belief in good luck and both depression and anxiety are best addressed by the theory that belief in good luck engenders optimistic traits and a reduced level of irrational beliefs.     

The central nucleus of the amygdala; a conduit for modulation of HPA axis responses to an immune challenge?

Physical stressors such as infection, inflammation and tissue injury elicit activation of the hypothalamic-pituitary-adrenal (HPA) axis. This response has significant implications for both immune and central nervous system function. Investigations in rats into the neural substrates responsible for HPA axis activation to an immune challenge have predominantly utilized an experimental paradigm involving the acute administration of the pro-inflammatory cytokine interleukin- 1β (IL-1β). It is well recognized that medial parvocellular corticotrophin-releasing factor cells of the paraventricular nucleus (mPVN CRF) are critical in generating HPA axis responses to an immune challenge but little is known about how peripheral immune signals can activate and/or modulate the mPVN CRF cells. Studies that have examined the afferent control of the mPVN CRF cell response to systemic IL-1β have centred largely on the inputs from brainstem catecholamine cells. However, other regulatory neuronal populations also merit attention and one such region is a component of the limbic system, the central nucleus of the amygdala (CeA). A large number of CeA cells are recruited following systemic IL-lβ administration and there is a significant body of work indicating that the CeA can influence HPA axis function. However, the contribution of the CeA to HPA axis responses to an immune challenge is only just beginning to be addressed. This review examines three aspects of HPA axis control by systemic IL-1β: (i) whether the CeA has a role in generating HPA axis responses to systemic IL-1β, (ii) the identity of the neural connections between the CeA and mPVN CRF cells that might be important to HPA axis responses and(iii) the mechanisms by which systemic IL-Iβ triggers the recruitment of CeA cells.     

A behavioral test of Horney’s linkage between authenticity and aggression: People living authentically are less-likely to respond aggressively in unfair situations

This study links Horney’s account of human growth and neurosis to authenticity by examining aggressive responses on the point subtraction aggressive paradigm, providing the first empirical test of whether authenticity can predict objective behavior. Data from undergraduate, postgraduate, and mature students demonstrate that when controlling for age, gender, trait-anger, agreeableness, and functional dimensions of coping, individuals who measure high on authentic-living respond less aggressively to attacks and counter-attacks in unfair situations. Authentic-living uniquely accounted for 14.2% of variance in aggressive-responses (r = −.37). The findings suggest that inauthenticity is a strong predictor of aggressive behavior, and therefore increasing levels of authenticity in counseling practice may reduce maladaptive levels of anger. We suggest future exploration between authenticity and models of emotional regulation will unearth the cause and effects of aggression within inauthentic individuals.     

System justification and the defense of committed relationship ideology

A consequential ideology in Western society is the uncontested belief that a committed relationship is the most important adult relationship and that almost all people want to marry or seriously couple (DePaulo & Morris, 2005). In the present article, we investigated the extent to which the system justification motive may contribute to the adoption of this ideology. In Studies 1 and 2, we examined whether a heightened motive to maintain the status quo would increase defense of committed relationship values. In Study 3, we examined the reverse association, that is, whether a threat to committed relationship ideology would also affect sociopolitical system endorsement. As past research has found that the justification of political systems depends upon how much these systems are perceived as controlling, in Study 4 we tested whether the defense of the system of committed relationships would also increase when framed as controlling. Results from Studies 1-4 were consistent with our hypotheses, but only for men. In Study 5, using cross-cultural data, we sought to replicate these findings correlationally and probe for a cause of the gender effect. Results from more than 33,000 respondents indicated a relationship (for men) between defense of the sociopolitical system and defense of marriage in countries where the traditional advantages of men over women were most threatened. In Studies 6 and 7, we investigated when this gender difference disappears. Results revealed that when we measured (Study 6) or manipulated (Study 7) personal relationship identity rather than relationship ideology, effects also emerge for women.     

How we Became the Schmams: Conceptualizations of Fairness in the Decision-Making Process for Latina/O Children

The current study examines 16 Latina/o fifth grade children's desires for a decision-making structure within a youth participatory action research (yPAR) program. When given the choices of consensus, majority rule, authoritarian rule, delegation, and random choice models, children chose random choice. Procedural, distributive and emotional justice were heavily weighted in their reasoning around fairness and decision making. Many thought random choice offered the best alternative because it flattened power hierarchies so that each child would, at some point, have the power to make a decision. Additionally, children argued that the neutrality of random choice allowed them to sidestep interpersonal tensions. Implications include how social identities inform definitions of fairness and how yPAR programs should work with youth around how they will make decisions.     

Development and Initial Validation of the Perceived Power Imbalance Scale

Relationship power, which refers to the ability to influence one’s romantic partner, is an important organizing principle in the assessment and treatment of couples. Power imbalance is predictive of various dimensions of marital quality, which explains why it is often a central focus of couple therapy. Despite the importance of relationship power in couple therapy, assessing power in clinical settings has been hindered by the lack of a validated measure of power that has high clinical utility. Data from 640 married couples associated with the Flourishing Families Project were used to develop the Perceived Power Imbalance Scale by conducting exploratory factor analysis, confirmatory factor analysis, dyadic predictive validity analysis, and measurement equivalence analysis. Although power has been conceptualized as consisting of both outcome power and process power, results indicated that the final scale consisted of four items that only tapped aspects of process power. The scale demonstrated good reliability and was a significant predictor of marital quality, marital instability, and depression.

     

Making sense of surveys and censuses: Issues in religious self-identification

Abstract

Censuses and surveys shape decisions, discourse and debates about people and their lived environments. The outcomes, in the case of a census, inform governments about resource distribution but also shape people's self-understanding about who they are and where they may be going. How people self-identify on censuses and surveys produces certain types of knowledge. This introduction emphasises the impact of those instruments on knowledge production and how numbers can be employed, often anecdotally, to further interests and claims. The way academics use and interpret such instruments has ethical and normative dimensions: numbers are not neutral but shape and are shaped by perceptions and identities. This introduction to a thematic issue of Religion introduces the contributing authors' diverse – historical, qualitative and quantitative – approaches that work together to produce their own kind of multi-disciplinary, academically located knowledge.     

Adapting Parent–Child Interaction Therapy for Deaf Families That Communicate via American Sign Language: A Formal Adaptation Approach

While our field has made positive strides in adapting psychotherapeutic interventions for diverse groups of people, considerable work is still needed in this area. We present our formal adaptation procedure for parent–child interaction therapy (PCIT) with Deaf persons. This includes a review of the cultural adaptation process for psychological interventions, including PCIT, as well as an introduction to Deaf culture. Details regarding the specific adaptation of PCIT for Deaf persons are outlined. We found that the utilization of a clear framework to guide the cultural adaptation process facilitated careful consideration of the numerous linguistic and cultural variables involved, while maintaining integrity of the treatment model. While the current focus was on adapting PCIT for Deaf families who communicate via American Sign Language, this framework can also be applied to other populations and/or interventions.
