Walking through a virtual environment improves perceived size within and beyond the walked space

Distances tend to be underperceived in virtual environments (VEs) by up to 50%, whereas distances tend to be perceived accurately in the real world. Previous work has shown that allowing participants to interact with the VE while receiving continual visual feedback can reduce this underperception. Judgments of virtual object size have been used to measure whether this improvement is due to the rescaling of perceived space, but there is disagreement within the literature as to whether judgments of object size benefit from interaction with feedback. This study contributes to that discussion by employing a more natural measure of object size. We also examined whether any improvement in virtual distance perception was limited to the space used for interaction (1–5 m) or extended beyond (7–11 m). The results indicated that object size judgments do benefit from interaction with the VE, and that this benefit extends to distances beyond the explored space.     

Is the Market Moral? Protestant Assessments of Market Society

Is the market moral? Do different Protestant traditions have competing views of “market society”? Despite the increasing diffusion of market logics in American society, scholars of religion have little empirical data on these questions. Employing discourse analysis of market-related topics in two prominent Christian periodicals over a twenty-year period, this paper compares evangelical and mainline Protestant evaluations of markets. We find that neither group views markets as redeeming, self-regulating, or value neutral, and both groups argue that markets require constraints. Evangelicals prioritize moral constraints on markets, while mainline Protestants prioritize governmental and democratic constraints. The degree of difference between the groups varies considerably by topic, however, depending on the degree of potential state intervention. We close by discussing our findings in light of recent debates over the relationship between religious conservatism and economic conservatism. We find that economic conservatism among evangelicals is driven at least as much by a commitment to collective voluntarism as by atomized individualism or free market ideology.     

Channels of Change: Contrasting Network Mechanisms in the Use of Interventions

This study informs community science, and seeks to narrow the research-to-practice gap, by examining how the interpersonal networks within a setting influence individuals' use of interventions. More specifically, it explores the role of two network mechanisms-cohesion and structural similarity-in urban elementary school teachers' use of interventions designed to improve academic and behavioral outcomes for students. Lagged regression models examine how position in advice giving networks influenced weekly use of the daily report card and peer assisted learning by kindergarten through fourth grade teachers in three schools. Results indicate that intervention use spreads among teachers with similar patterns of advice-giving relationships (i.e., via structural similarity), rather than from teachers who are sources of advice (i.e., via cohesion). These results are consistent with findings in other settings, and suggest that researchers wishing to increase the use of an intervention should select change agents based on their patterns of their relationships, rather than on their direct connections.     

Power as a Structural Phenomenon

In an effort to inform empowerment theory and research, this paper provides a structural conception of power. First, we examine the essential features present in three dominant conceptions of power in community psychology: social power, psychopolitical power, and relational power. Next, commonalities in the key features of power identified by these conceptions are explored and pared down to yield a more parsimonious conception of power that is grounded only in the structural pattern of relationships through which resources are exchanged. Drawing on social exchange theory, we offer a method for measuring this streamlined, structural conception of power that allows for its more precise examination. Finally, we discuss the implications of a structural conception and measurement of power for targeting and facilitating empowering processes and evaluating empowered outcomes.     

The pull of the past: when do habits persist despite conflict with motives?

To identify the factors that disrupt and maintain habit performance, two field experiments tested the conditions under which people eat out of habit, leading them to resist motivational influences. Habitual popcorn eaters at a cinema were minimally influenced by their hunger or how much they liked the food, and they ate equal amounts of stale and fresh popcorn. Yet, mechanisms of automaticity influenced habit performance: Participants ate out of habit, regardless of freshness, only when currently in the context associated with past performance (i.e., a cinema; Study 1) and only when eating in a way that allowed them to automatically execute the response cued by that context (i.e., eating with their dominant hand; Study 2). Across all conditions, participants with weaker cinema-popcorn-eating habits ate because of motivations such as liking for the popcorn. The findings reveal how habits resist conflicting motives and provide insight into promising mechanisms of habit change.     

Revisiting the Zahavi–Brough/Sokolowski Debate

In 1999, Dan Zahavi’s Self Awareness and Alterity: A Phenomenological Investigation initiated a critique of the standard interpretation of the distinction between the second and third levels of Husserl’s analysis of time-constituting consciousness. At stake was the possibility of a coherent account of self-awareness (Zahavi’s concern), but also the possibility of prereflectively distinguishing the acts of consciousness (Brough and Sokolowski’s rebuttal of Zahavi’s critique). Using insights gained from Husserl’s Analyses Concerning Passive Synthesis rather than the work on time-consciousness, this paper provides a new, more precise vocabulary in which to carry on the debate, in the hopes of bringing it to a mutually satisfactory resolution. After briefly laying out the terms of the Zahavi–Brough/Sokolowski debate (Sect. 2), I then elaborate a three-fold distinction in consciousness from the Analyses (Sect. 3) and relate that back to the issue of objectivity in the debate (Sect. 4). I end by suggesting how this three-fold model from the Analyses helps us preserve the essentially tripartite structure (as Brough and Sokolowski insist we do) while not making one of these levels the object of another (in keeping with Zahavi’s critique) (Sect. 5).     

Positive God Images and Positive Emotions toward God: Exploring Variations among Whites,Blacks, and Hispanics

How people view God is an important part of religious life. The purpose of this study is to see if four positive God image measures and two measures of positive emotions toward God vary among Whites, Blacks, and Hispanics. The data come from a recent nationwide survey in the United States (N = 2500). The findings reveal that, compared to Whites and Hispanics, Blacks have more positive image of God scores on all four measures. The data indicate that Blacks are also more likely than Whites and Hispanics to have strong positive emotions toward God. In contrast, consistent differences between Hispanics and Whites failed to emerge across all of the study measures.     

Clinical Decision-Making Following Disasters: Efficient Identification of PTSD Risk in Adolescents

The present study aimed to utilize a Receiver Operating Characteristic (ROC) approach in order to improve clinical decision-making for adolescents at risk for the development of psychopathology in the aftermath of a natural disaster. Specifically we assessed theoretically-driven individual, interpersonal, and event-related vulnerability factors to determine which indices were most accurate in forecasting PTSD. Furthermore, we aimed to translate these etiological findings by identifying clinical cut-off recommendations for relevant vulnerability factors. Our study consisted of structured phone-based clinical interviews with 2000 adolescent-parent dyads living within a 5-mile radius of tornados that devastated Joplin, MO, and northern Alabama in Spring 2011. Demographics, tornado incident characteristics, prior trauma, mental health, and family support and conflict were assessed. A subset of youth completed two behavioral assessment tasks online to assess distress tolerance and risk-taking behavior. ROC analyses indicated four variables that significantly improved PTSD diagnostic efficiency: Lifetime depression (AUC = .90), trauma history (AUC = .76), social support (AUC = .70), and family conflict (AUC = .72). Youth were 2–3 times more likely to have PTSD if they had elevated scores on any of these variables. Of note, event-related characteristics (e.g., property damage) were not related to PTSD diagnostic status. The present study adds to the literature by making specific recommendations for empirically-based, efficient disaster-related PTSD assessment for adolescents following a natural disaster. Implications for practice and future trauma-related developmental psychopathology research are discussed.     

Network Analysis in Community Psychology: Looking Back,Looking Forward

Network analysis holds promise for community psychology given the field's aim to understand the interplay between individuals and their social contexts. Indeed, because network analysis focuses explicitly on patterns of relationships between actors, its theories and methods are inherently extra‐individual in nature and particularly well suited to characterizing social contexts. But, to what extent has community psychology taken advantage of this network analysis as a tool for capturing context? To answer these questions, this study provides a review of the use network analysis in articles published in American Journal of Community Psychology . Looking back, we describe and summarize the ways that network analysis has been employed in community psychology research to understand the range of ways community psychologists have found the technique helpful. Looking forward and paying particular attention to analytic issues identified in past applications, we provide some recommendations drawn from the network analysis literature to facilitate future applications of network analysis in community psychology.     

Differences in attributions of mental illness and social distance for portrayals of four mental disorders

For individuals with mental illness, others' perceptions of mental illness often limit integration into communities. Perceptions of mental illness manifest as social stigma in the form of social distance and may depend on individuals' attributions of the origins of mental illness. 180 university students completed a survey on attribution of mental illness and social distance across several disorders (psychiatric and physical). Participants indicated greater social distance for severe mental illness (i.e., schizophrenia) than less severe mental illness and physical illness. More desire for social distance may be related to unfamiliarity with severe mental illness rather than less severe mental and physical illnesses. Greater understanding of how individuals perceive mental illness can inform efforts to educate the public.
