Adult visual experience promotes recovery of primary visual cortex from long-term monocular deprivation

Prolonged visual deprivation from early childhood to maturity is believed to cause permanent visual impairment. However, there have been case reports of substantial improvement of binocular vision in human adults following lifelong visual impairment or deprivation. These observations, together with recent findings of adult ocular dominance plasticity in rodents, led us to re-examine whether adult primary visual cortex (V1) is capable of any recovery following long-term monocular deprivation starting in development. Using mice as a model, we find that monocular deprivation from early development to mature ages (well past the critical period) severely impaired binocular vision by reducing the amplitude of responses elicited by stimulation of the deprived eye. Surprisingly, we find little effect on nondeprived eye responses. Restoration of binocular vision in mature adults yields modest but significant improvement of visual responses in V1. Remarkably, we find that when binocular vision is followed by occlusion of the nondeprived eye, visual responses in V1 recover almost fully, as measured by visual evoked potential amplitude, spatial frequency threshold, and single-unit activity. We conclude that adult V1 can recover from long-term deprivation when provided with an optimal regimen of visual experience.     

We didn't say that: Challenges in the Public Dissemination of a Research Finding with Controversial Implications

In the March 2014 issue of American Journal of Community Psychology, we published an article that examined the tension between two core values in the field of community psychology: promoting contextual conditions that foster respect for diversity and promoting contextual conditions that foster sense of community. We concluded that processes of social network formation could help explain why diversity and sense of community are seemingly incompatible goals. The study's findings initially disseminated through the usual academic channels, and later through mainstream media outlets. However, they also eventually appeared on blogs and discussion forums devoted to white nationalism. The findings were viewed there as having demonstrated the evils of diversity, and thus having vindicated the white nationalist agenda. As a result, we were forced to consider whether and how to set the record straight. In this first‐person narrative, we describe our study's journey from AJCP to white nationalist blogs, discussing how we ultimately responded to the situation, and concluding with some lessons learned.     

Animal Rescue as Civil Disobedience

Apparently illegal cases of animal rescue can be either open or covert: ‘open rescue’ is associated with organizations such as Animal Liberation Victoria and Animal Liberation New South Wales; ‘covert rescue’ is associated with the Animal Liberation Front. While the former seems to qualify non-controversially as civil disobedience I argue that (irrespective of other considerations such as effectiveness or advisability) at least some instances of the latter could also qualify as civil disobedience just so long as various norms of civility (e.g. norms concerning recognition of others, the avoidance of violence and threats) are satisfied. The case for such a move is defended against objections that covertness is (1) inherently suspect; (2) a failure to accept responsibility; and (3) inconsistent with civil disobedience as a form of communication. Against such objections, the paper emphasizes the importance of respecting the open texture of the concept of civil disobedience if it is to be of continuing relevance against the backdrop of changing forms of non-violent dissent.     

Factor structure and differential validity of the expanded Brief Psychiatric Rating Scale

The Brief Psychiatric Rating Scale (BPRS) is one of the most widely used measures in psychiatric outcome and clinical psychopharmacology research. To date, however; research on the psychometric properties of the expanded version of the BPRS (BPRS-E) has been limited. An exploratory factor analysis (n = 360) using maximum likelihood extraction with oblimin rotation found a four-factor solution (Thought Disturbance, Animation, Mood Disturbance, Apathy) to underlie the BPRS-E. Furthermore, these factors were logical in nature and estimates of internal consistency were acceptable. A confirmatory factor analysis conducted on a second, independent sample (n = 280)found that for the five models currently available in the literature, the model developed herein provided the best fit to the data. Again, estimates of internal consistency were found acceptable. Finally, the four factors demonstrated appropriate differential validity with regards to both demographic variables and various psychiatric diagnoses.     

Why managers should care about fairness: the effects of aggregate justice perceptions on organizational outcomes

This work examines the aggregation of justice perceptions to the departmental level and the business-unit level, the impact of these aggregate perceptions on business-unit-level outcomes, and the usefulness of the distinction between procedural and interpersonal justice at different levels of analysis. Latent variables analyses of individual-level and department-level data from 4,539 employees in 783 departments at 97 hotel properties showed that the 2 justice types exercise unique paths of impact on employees' organizational commitment and thus on turnover intentions and discretionary service behavior. Business-unit-level analyses further demonstrate paths of association between aggregate justice perceptions, aggregate commitment levels, and the business-unit-level outcomes of employee turnover rates and customer satisfaction ratings.     

MMPI-2 as a predictor of change in PTSD symptom clusters: a further analysis of the Forbes et al. (2002) data set

In this study, we reanalyzed the Forbes et al. (2002) data set to examine the Minnesota Multiphasic Personality Inventory (MMPI-2; Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989) as a differential predictor of change across posttraumatic stress disorder symptom clusters following treatment in 141 Vietnam veterans. A series of partial correlation and linear multivariate regression analyses, controlling for initial symptom severity, identified several scales predictive of symptom change. None of the MMPI-2 scales, however, emerged as predictors of change in reexperiencing symptoms. Social alienation and marital distress were the most potent predictors for avoidance symptoms. Anger, alcohol use, and hypomania were the most potent predictors for the hyperarousal symptoms. Of the personality disorders, borderline personality was the strongest predictor of change in the avoidance and hyperarousal clusters. Further replication of the findings of this article and those reported by Forbes et al. (2002) is required.     

Psychological Types of Male Evangelical Missionary Personnel Training in England: A Role for Thinking Type Men?

A sample of 92 male evangelical missionary personnel completed Form G (Anglicised) of the MBTI. The two predominant types among this group were ESTJ (24%) and ISTJ (15%). In the group as a whole there were clear preferences for extraversion over introversion, for sensing over intuition, for thinking over feeling, and for judging over perceiving.     

Coordinating perceptually grounded categories through language: a case study for colour

This article proposes a number of models to examine through which mechanisms a population of autonomous agents could arrive at a repertoire of perceptually grounded categories that is sufficiently shared to allow successful communication. The models are inspired by the main approaches to human categorisation being discussed in the literature: nativism, empiricism, and culturalism. Colour is taken as a case study. Although we take no stance on which position is to be accepted as final truth with respect to human categorisation and naming, we do point to theoretical constraints that make each position more or less likely and we make clear suggestions on what the best engineering solution would be. Specifically, we argue that the collective choice of a shared repertoire must integrate multiple constraints, including constraints coming from communication.     

The MMPI-2 as a predictor of symptom change following treatment for posttraumatic stress disorder

This study sought to examine the impact of personality factors on symptom change following treatment for 141 Vietnam veterans with chronic combat-related posttraumatic stress disorder (PTSD) using the Minnesota Multiphasic Personality Inventory-2 (Butcher, Dahlstrom, Graham, Tellegen, & Kaemmer, 1989). A series of partial correlation and linear multivariate regression analyses identified social alienation, associated with anger and substance use, as the most potent negative predictor of symptom change. Of the scales assessing personality disorder, Borderline Personality was identified as the strongest negative predictor of outcome. Regression analyses examining the most salient scales identified 5 items that contributed 14% of the variance in the prediction of change scores independently of the 21% accounted for by pretreatment PTSD severity.
