Epistemological beliefs and thinking about everyday controversial issues

The authors investigated the relationship between individuals' beliefs about the nature of knowledge and the nature of learning (epistemological beliefs) and their thinking about everyday controversial issues. Adults (N = 174) ranging in age from 17 to 71 years old with a mean age of 38 completed the Schommer Epistemological Questionnaire (M. Schommer, 1990), which assessed their beliefs in the certainty and organization of knowledge and the speed and control of learning. After they had completed the questionnaire, they responded to a series of questions about two controversial issues that had been discussed in the local newspaper. Regression analyses indicated that the more the participants believed in complex and tentative knowledge, the more likely they were to take on multiple perspectives, be willing to modify their thinking, withhold ultimate decisions until all information was available, and acknowledge the complex, tentative nature of everyday issues. Epistemological beliefs that are heavily influenced by a higher level of education appear to relate to thinking beyond the classroom, and introducing controversial issues into the curriculum may reciprocally foster the development of epistemological beliefs.     

To stay or to go, to speak or stay silent, to act or not to act: moral distress as experienced by psychologists

The moral distress of psychologists working in psychiatric and mental health care settings was explored in an interdisciplinary, hermeneutic phenomenological study situated at the University of Alberta, Canada. Moral distress is the state experienced when moral choices and actions are thwarted by constraints. Psychologists described specific incidents in which they felt their integrity had been compromised by such factors as institutional and interinstitutional demands, team conflicts, and interdisciplinary disputes. They described dealing with the resulting moral distress by such means as silence, taking a stance, acting secretively, sustaining themselves through work with clients, seeking support from colleagues, and exiting. Recognizing moral distress can lead to a significant shift in the way we perceive moral choices and understand the moral context of practice.     

Reversal of motor learning in the vestibulo-ocular reflex in the absence of visual input

Motor learning in the vestibulo-ocular reflex (VOR) and eyeblink conditioning use similar neural circuitry, and they may use similar cellular plasticity mechanisms. Classically conditioned eyeblink responses undergo extinction after prolonged exposure to the conditioned stimulus in the absence of the unconditioned stimulus. We investigated the possibility that a process similar to extinction may reverse learned changes in the VOR. We induced a learned alteration of the VOR response in rhesus monkeys using magnifying or miniaturizing goggles, which caused head movements to be accompanied by visual image motion. After learning, head movements in the absence of visual stimulation caused a loss of the learned eye movement response. When the learned gain was low, this reversal of learning occurred only when head movements were delivered, and not when the head was held stationary in the absence of visual input, suggesting that this reversal is mediated by an active, extinction-like process.     

A tutorial on Bayesian nonparametric models

A key problem in statistical modeling is model selection, that is, how to choose a model at an appropriate level of complexity. This problem appears in many settings, most prominently in choosing the number of clusters in mixture models or the number of factors in factor analysis. In this tutorial, we describe Bayesian nonparametric methods, a class of methods that side-steps this issue by allowing the data to determine the complexity of the model. This tutorial is a high-level introduction to Bayesian nonparametric methods and contains several examples of their application.     

Can survival processing enhance story memory? Testing the generalizability of the adaptive memory framework

Research from the adaptive memory framework shows that thinking about words in terms of their survival value in an incidental learning task enhances their free recall relative to other semantic encoding strategies and intentional learning (Nairne, Pandeirada, & Thompson, 2008). We found similar results. When participants used incidental survival encoding for a list of words (e.g., "Will this object enhance my survival if I were stranded in the grasslands of a foreign land?"), they produced better free recall on a surprise test than did participants who intentionally tried to remember those words (Experiment 1). We also found this survival processing advantage when the words were presented within the context of a survival or neutral story (Experiment 2). However, this advantage did not extent to memory for a story's factual content, regardless of whether the participants were tested by cued recall (Experiment 3) or free recall (Experiments 4-5). Listening to a story for understanding under intentional or incidental learning conditions was just as good as survival processing for remembering story content. The functionalist approach to thinking about memory as an evolutionary adaptation designed to solve reproductive fitness problems provides a different theoretical framework for research, but it is not yet clear if survival processing has general applicability or is effective only for processing discrete stimuli in terms of fitness-relevant scenarios from our past.     

How does frustration make you feel? A motivational analysis in exercise context

Not all exercisers experience the same psychological benefits. The understanding of motivational processes and their relation with emotional consequences of exercise should be considered in the context of the exercisers motivation. This was a cross-sectional study of 153 gym users (M?=?36.21 years, SD?=?8.44; 44.9% men, 55.1% women; M years exercise?=?8). Weekly attendance averaged 4.3 (SD?=?2.6) sessions per week; reported exertion intensity was 5.6 (SD?=?2.1) (scale: 0–11). The basic psychological needs (BPNs) posited by self-determination theory, motivational regulation, and emotional response to physical activity, were measured. Possible mediators of BPN-emotion relationships were analyzed. BPN satisfaction was associated with a positive emotional response to exercise which was partially mediated by the effect of autonomous regulation on positive activation and psychological well-being. Mediation models indicated that the negative effects of BPN frustration were counteracted by autonomous regulation. Exercise professionals should be able to create psychologically supportive contexts and identify behaviors associated with need frustration so as to enhance emotional responses to exercise.     

Seeing it differently: visual processing in autism

Several recent behavioral and neuroimaging studies have documented an impairment in face processing in individuals with Autism Spectrum Disorder (ASD). It remains unknown, however, what underlying mechanism gives rise to this face processing difficulty. One theory suggests that the difficulty derives from a pervasive problem in social interaction and/or motivation. An alternative view proposes that the face-processing problem is not entirely social in nature and that a visual perceptual impairment might also contribute. The focus of this review is on this latter, perceptual perspective, documenting the psychological and neural alterations that might account for the face processing impairment. The available evidence suggests that perceptual alterations are present in ASD, independent of social function.     

Minority students of color and the psychology graduate pipeline: disquieting and encouraging trends, 1989-2003

Trends since 1989 in the minority graduate pipeline in psychology are examined, with special focus on trends in recent years. Encouraging trends generally outweigh troubling ones at lower levels of the pipeline. However, in recent years disquieting trends dominate at the higher pipeline levels. Promising trends include a rise in the percentage (to nearly 25%) of minority psychology students receiving the bachelor's degree and a rise to more than 20% receiving the master's degree. Troubling trends include the stalling of growth in minority PhD degree receipt since 1999 and the lack of growth in the percentage of African American and Hispanic/Latino(a) students entering PhD departments. Given the mixed findings, one of the highest priorities for psychology must be continued and persistent efforts to develop practices and policies that enhance recruitment, high levels of achievement, and degree receipt for students of color.
