Fusion prevents the redundant signals effect: evidence from stereoscopically presented stimuli

In a simple reaction time (RT) experiment, visual stimuli were stereoscopically presented either to one eye (single stimulation) or to both eyes (redundant stimulation), with brightness matched for single and redundant stimulations. Redundant stimulation resulted in two separate percepts when noncorresponding retinal areas were stimulated, whereas it resulted in a single fused percept when corresponding areas were stimulated. With stimulation of noncorresponding areas, mean RT was shorter to redundant than to single stimulation, replicating the redundant signals effect (RSE) commonly found with visual stimuli. With stimulation of corresponding areas, however, no RSE was observed. This suggests that the RSE is driven by the number of percepts rather than by the number of stimulated receptors or sensory organs. These results are consistent with previous findings in the auditory modality and have implications for models of the RSE.     

The Emotional Citizen: Emotion as a Function of Political Sophistication

Scholars and popular commentators have often stereotyped emotion as a tool that citizens use to reason about politics in place of hard fact and critical thought. Indeed, critics have often seen emotion as a potentially dangerous force that can sway the unsophisticated masses to undesirable ends. This article challenges the view that emotion is an outgrowth of low sophistication, arguing that high sophisticates are more likely to experience emotion in reaction to politics and that emotions are more influential on the political behavior of high sophisticates. Drawing upon appraisal theory, this article develops a theory of how political engagement elicits emotionality about politics, and how emotion interacts with understanding and motivation to produce its greatest impact on the behavior of those citizens who are the most politically sophisticated. Behavioral effects are examined in the contexts of presidential voting behavior and Iraq War policy attitudes. Hypotheses are tested on pooled American National Election Studies (ANES) data and an original web‐based survey of undergraduates.     

Unskilled but aware: reinterpreting overconfidence in low-performing students

People are generally overconfident in their self-assessments and this overconfidence effect is greatest for people of poorer abilities. For example, poor students predict that they will perform much better on exams than they do. One explanation for this result is that poor performers in general are doubly cursed: They lack knowledge of the material, and they lack awareness of the knowledge that they do and do not possess. The current studies examined whether poor performers in the classroom are truly unaware of their deficits by examining the relationship between students' exam predictions and their confidence in these predictions. Relative to high-performing students, the poorer students showed a greater overconfidence effect (i.e., their predictions were greater than their performance), but they also reported lower confidence in these predictions. Together, these results suggest that poor students are indeed unskilled but that they may have some awareness of their lack of metacognitive knowledge.     

Depression and quality of informal care: a longitudinal investigation of caregiving stressors

This research examined longitudinal associations between caregiving stressors, caregiver depression, and quality of care. Informal caregivers of elderly care recipients were interviewed at baseline (N = 310) and again one year later (N = 213). Hierarchical regression analyses indicated that increases in caregiving stressors (i.e., caregiver physical health symptoms, caregiver activity restriction, and care recipient controlling and manipulative behavior) were related to increased caregiver depression. In turn, increased caregiver depression and decreased caregiver respectful behavior predicted increases in potentially harmful behavior. These results extend previous cross-sectional findings and indicate that changes in caregiving stressors, caregiver depression, and caregiver respect over time may signal that intervention is warranted in order to forestall or prevent poor quality of care.     

Growing Suburbs,Relocating Churches: The Suburbanization of Protestant Churches in the Chicago Region, 1925–1990

This study examines the locations of Protestant churches in the Chicago region between 1925 and 1990 based on data from the Church Federation of Greater Chicago. The analysis adds two insights to existing explanations of white flight and the corresponding suburbanization of churches: suburbanization patterns were not the same across Protestant groups and churches moving to the suburbs were adding to churches already present in those communities. As the percentage of suburban Protestant churches in the Chicago region started increasing after 1925, the new suburban locations were influenced by settlement patterns in the Chicago region—first along railroad lines and then in between with new sites easier to access by automobile—in addition to racial changes in Chicago neighborhoods and the ethnic composition of denominations. Suggestions for further research include examining the suburbanization of religious groups in more metropolitan regions (particularly beyond the North), comparing the discussions about moving to the suburbs across denominations and congregations, and considering how religious congregations have helped shape suburban communities.     

Data presentation options to manage variability in physical activity research

This paper presents seven tactics for managing the variability evident in some physical activity data. High levels of variability in daily step‐count data from pedometers or accelerometers can make typical visual inspection difficult. Therefore, the purpose of the current paper is to discuss several strategies that might facilitate the visual interpretation of highly variable data. The seven strategies discussed in this paper are phase mean and median lines, daily average per week, weekly cumulative, proportion of baseline, 7‐day moving average, change point detection, and confidence intervals. We apply each strategy to a data set and discuss the advantages and disadvantages.     

The Role of Family Income Dynamics in Predicting Trajectories of Internalizing and Externalizing Problems

Economic disparities in children’s behavioral functioning have been observed in prior research. Yet, studies have ignored important perspectives from developmental psychopathology and have not delineated how aspects of income dynamics (i.e., cumulative family income versus income volatility) differentially relate to behavior problems. To address these limitations, the current study examined how both cumulative income and income volatility predict trajectories of children’s internalizing and externalizing problems from kindergarten through fifth grade in a nationally representative sample of 10,900 children (51.4 % male). Results showed four distinct trajectories of internalizing problems and five distinct externalizing trajectories. Family income dynamics were related to trajectory group membership. Specifically, increased cumulative income decreased risk of membership in mid-increasing and mid-stable internalizing groups, and children whose families experienced multiple waves of income loss were 2.4 times as likely to be in the mid-increasing group instead of the low-stable group. With respect to externalizing, higher cumulative income increased the likelihood of belonging in the group exhibiting stably low externalizing problems. Experiencing income loss increased the risk of belonging in the trajectory group exhibiting chronically high externalizing behaviors. These results enhance our knowledge of the role of family income in the development of behavior problems.     

I Am a Mystery to Myself

Throughout my lifetime I have had a vague sense of my identity. There were no distinct memories or stories from my childhood and adolescence to provide me with the recognition, much less an appreciation, for who I was in the world. It wasn’t until I entered psychotherapy that revelations about my family life came into understanding. This was not from any recollecting of actual events but from the indirect observations of families where being engaged with each other had occurred. Through psychoanalysis, reading a variety of psychoanalytic thinkers, and by taking up my own writing I was encouraged to discover myself, even at the cost of the sorrow of never having that encouragement in growing up, the cost that comes with the exploration. Where no childhood home was to be found a new one was to be created instead.     

Testing a bilinear domain-specific model of acculturation and enculturation across generational status

This study attempted to replicate Miller's (2007) finding that a bilinear domain-specific model of Asian American acculturation demonstrated superior model fit when compared to unilinear and bilinear domain-generic models. Current confirmatory factor analytic tests of competing acculturation models in a cross-validation sample of 306 participants were consistent with Miller's findings. In addition, this study provided novel findings regarding the nature of the acculturation process by testing the bilinear domain-specific model across 1st and 2nd generation samples. Specifically, the generational status moderator hypothesis-that a unilinear model of acculturation would be most appropriate for 1st generation individuals and a bilinear model of acculturation would be most appropriate for 2nd generation individuals-was tested with 494 1st and 2nd generation Asian Americans. Contrary to the assumptions of the generational status moderator hypothesis, present findings demonstrated the appropriateness of the bilinear domain-specific model for both 1st and 2nd generation Asian Americans. Present findings also revealed a pattern of shared and unique relationships between cultural orientations and acculturation domains across generations. Implications for research and counseling are explored.
