Lifespan Differences in a Self Determination Theory Model of Eudaimonia: A Cross-Sectional Survey of Younger,Middle-Aged,and Older Adults

Despite the myriad physical, cognitive, and social losses that are increasingly common as we age, a growing body of evidence suggests that aging is positively associated with mental health and well-being. The majority of this evidence is in the form of mental health, personality, and subjective/hedonic well-being outcomes; far less is known about lifespan differences in eudaimonic well-being. The objective of this study was to examine differences across three age groups in a relatively recent model of eudaimonia informed by self-determination theory that focuses on the process of living well, but also acknowledges outcomes of that process. In comparison to young (n = 66) and middle-aged adults (n = 66), older adults (n = 66) were especially likely to be living eudaimonically (i.e., to have intrinsic aspirations, goal autonomy, mindfulness, and basic psychological need fulfillment). The effect of age on well-being outcomes was mixed; the oldest group reported the highest levels of life satisfaction (hedonic well-being) but the lowest levels of purpose and growth (eudaimonic well-being) in comparison to their younger counterparts. As predicted by the model, basic psychological need fulfillment mediated the relationship between motivational constructs and well-being outcomes. Furthermore, the model applied equally well to younger, middle-aged, and older adults. Our results are consistent with recent theoretical models emphasizing the socioemotional benefits of aging, as well as potential challenges to well-being that exist in later life.     

When words and space collide: Spatial attention interacts with lexical access during word recognition

Recent research has suggested an important role for spatial attention in reading, however the nature of this influence is unclear. Further, it has been shown that intention to engage in linguistic processing can enhance lexical processing. Therefore, we developed a novel paradigm to examine the impact of spatial attention on primed and unprimed lexical processing. In a lexical decision task, targets were preceded by a cue to lexical access and spatial location simultaneously. Results indicated that on spatially valid trials, the lexical cuing effect was large and word processing was enhanced, suggesting that spatial attention influences lexical access. On spatially invalid trials, lexical cuing effects were significantly decreased, resulting in a spatial cuing by lexical cuing interaction. Results from this experiment provide evidence that spatial attention interacts with lexical access during word processing. This novel paradigm provides a new avenue for exploring the relations between spatial attention and reading processes.     

Feature integration and spatial attention: common processes for endogenous and exogenous orienting

Briand (J Exp Psychol Hum Percept Perform 24:1243–1256, 1998) and Briand and Klein (J Exp Psychol Hum Percept Perform 13:228–241, 1987) demonstrated that spatial cueing effects are larger for detecting conjunction of features than for detecting simple features when spatial attention is oriented exogenously, and not when attention is oriented endogenously. Their results were interpreted as if only exogenous attention affects the posterior spatial attention system that performs the feature binding function attributed to spatial attention by Treisman’s feature integration theory (FIT; 1980). In a series of 6 experiments, we attempted to replicate Briand’s findings. Manipulations of distractor string size and symmetry of stimulus presentation left and right from fixation were implemented in Posner’s cueing paradigm. The data indicate that both exogenous and endogenous cueing address the same attentional mechanism needed for feature binding. The results also limit the generalisability of Briand’s proposal concerning the role of exogenous attention in feature integration. Furthermore, the importance to control the effect of unintended attentional capture in a cueing task is demonstrated.     

Both Sides of the Coin: Randomization from the Perspectives of Physician-Investigators and Patient-Subjects

Randomization is the "gold standard" design for clinical research trials, and is accepted as the best way to reduce bias. Although some controversy remains over this matter, we believe equipoise is the fundamental ethical requirement for conducting a randomized clinical trial. Despite much attention to the ethics of randomization, the moral psychology of this study design has not been explored. This paper analyzes the ethical tensions that arise from conducting these studies, and examines the moral psychology of this design from the perspectives of physician-investigators and patient-subjects. We conclude with a discussion of the practical implications of this analysis.     

Polkinghorne and Cartwright on Pluralism and Metaphysics

Abstract

This paper reviews the natural philosophies of John Polkinghorne and Nancy Cartwright, with particular emphasis on the role of pluralism in their respective writings. While often motivated by distinct projects, their philosophies display some interesting and perhaps unexpected similarities. It is suggested that Polkinghorne's views are not far away from some of Cartwright's proposals, and further that certain debates about God's providential action could be helpfully reoriented if the insistence on natural laws as a centerpiece of scientific explanation were relinquished.     

The Search for Mathematical Creativity: Identifying Creative Potential in Middle School Students

The identification of creative potential in mathematics poses many challenges. Much of the research into the identification of mathematical creativity has focused on the development of measurement instruments. Scoring of these instruments is time consuming and subject to scorer interpretation, limiting their use. This study sought a simpler means to obtain indicators of creative potential in mathematics. Existing instruments were used to explore the relationship between mathematical creativity and mathematical achievement, attitude towards mathematics, self-perception of creative ability, gender, and teacher perception of mathematical talent and creative ability. Data were gathered from 89 7th graders in a suburban Connecticut school. The regression model predicted 35% of the variance in mathematical creativity scores. Mathematical achievement was the strongest predictor accounting for 23% of the variance. Student attitudes towards mathematics, self-perception of their own creative abilities, and gender contributed the remaining 12% of variance. Interpretation of the relative importance of the independent variables was complicated by correlations among them.     

A Thematic Analysis of Spectator Violence at Sporting Events in North America

This study examines aggravating and mitigating circumstances surrounding spectator fights at stadiums and arenas in North America. Data were collected utilizing a sample of video recordings posted to a popular video-sharing website. A thematic analysis of the data reveals several influences including the role of team allegiances, alcohol use, security presence, and bystander behavior. Potential preventive and reactive interventions to discourage violence in this setting are discussed and evaluated.     

Mental Rotation in False Belief Understanding

This study examines the spontaneous use of embodied egocentric transformation (EET) in understanding false beliefs in the minds of others. EET involves the participants mentally transforming or rotating themselves into the orientation of an agent when trying to adopt his or her visuospatial perspective. We argue that psychological perspective taking such as false belief reasoning may also involve EET because of what has been widely reported in the embodied cognition literature, showing that our processing of abstract, propositional information is often grounded in concrete bodily sensations which are not apparently linked to higher cognition. In Experiment 1, an agent placed a ball into one of two boxes and left. The ball then rolled out and moved either into the other box (new box) or back into the original one (old box). The participants were to decide from which box they themselves or the agent would try to recover the ball. Results showed that false belief performance was affected by increased orientation disparity between the participants and the agent, suggesting involvement of embodied transformation. In Experiment 2, false belief was similarly induced and the participants were to decide if the agent would try to recover the ball in one specific box. Orientation disparity was again found to affect false belief performance. The present results extend previous findings on EET in visuospatial perspective taking and suggest that false belief reasoning, which is a kind of psychological perspective taking, can also involve embodied rotation, consistent with the embodied cognition view.
