Testing different interpretations for the mistaken belief that rays exit the eyes during vision

Research has shown that children and adults believe that emissions from the eye occur during the act of vision. Such beliefs are similar to ancient extramission theories of perception. In Study 1, the authors tested the idea that extramission beliefs might stem from people's thinking about what might occur during vision as opposed to what is necessary for seeing. Training participants to think about what is necessary for vision, however, had no effect on extramission responses. The results of Study 2 indicated that emphasizing the idea of visual input led to a decline in extramission responses and supported the hypothesis that extramission notions stem from the outer-oriented phenomenology of vision.     

Politics perceptions as moderator of the political skill – job performance relationship: A two-study, cross-national, constructive replication

We developed a two-study, cross-national, constructive replication to examine the role of organizational politics perceptions as a contextual moderator of the political skill – job performance relationship. Specifically, we hypothesized that high levels of political skill would demonstrate its strongest positive effects on job performance when politics perceptions were perceived as low. Conversely, we hypothesized that political skill would demonstrate no relationship with job performance under conditions of high politics perceptions. Across studies conducted both in the United States and Greece, the hypothesis received strong support. In settings characterized by lower perceived politics, high levels of political skill predicted significant increases in job performance, whereas these effects were attenuated in environments characterized by high perceived politics. Contributions and implications of this research, strengths and limitations, and directions for future study are discussed.     

A Challenge for Soft Line Replies to Manipulation Cases

Cases involving certain kinds of manipulation seem to challenge compatibilism about responsibility-grounding free will. To deal with such cases many compatibilists give what has become known as a ‘soft line’ reply. In this paper I present a challenge to the soft line reply. I argue that any relevant case involving manipulation—and to which a compatibilist might wish to give a soft line reply—can be transformed into one supporting a degree of moral responsibility through the addition of libertarian elements (such as alternative possibilities of a kind unavailable under determinism and executive control of the sort commonly associated with agent-causation). From a compatibilist’s perspective the subtraction of libertarian elements should make no difference to any assessment of the agent’s responsibility. The compatibilist should therefore judge the agent morally responsible after the removal of the libertarian elements. Yet removal of the libertarian elements returns the case to its original form and thus what started out as a soft line has now collapsed into a hard line reply. Various ways of resisting my argument are considered, but each is shown to carry important burdens.     

P-E Fit as moderator of the accountability – employee reactions relationships: Convergent results across two samples

The current two-sample investigation, which incorporated Conservation of Resources (COR) and Person-Environment (P-E) fit theories, investigated the interaction effects of felt accountability × P-E fit on the work outcomes of job satisfaction, organizational commitment, depressed mood, and work intensity. Consistent with the conceptual underpinnings of felt accountability as either a threat or opportunity, satisfaction, work intensity, and organizational commitment increased in settings possessing both heightened answerability and high levels of P-E fit. Further, individuals reported a reduction in depressed mood when heightened accountability was coupled with high P-E fit perceptions. These findings were consistent across samples providing evidence of generalizability. Implications, strengths and limitations, and directions for future research are discussed.     

Type 2 Diabetes Mellitus and Cognitive Performance in a Population-Based Sample of the Oldest Old: Impact of Comorbid Dementia

We examined the relationship between type 2 diabetes mellitus and cognitive function in a population-based sample of very old people. The sample comprised 338 persons, aged 80-93 years (mean age 83.5 years), of whom 70 persons had type 2 diabetes mellitus. Measures of cognitive functioning included tests of perceptual speed, visuo-spatial ability, inductive reasoning, short-term memory, semantic memory, episodic memory, and the Mini-Mental State Examination. Regression analyses showed that type 2 diabetes mellitus duration was related to test performance across all cognitive domains, with the exception of short-term memory, such that longer duration was associated with lower test performance. When cases with dementia were excluded from the sample, further analyses showed that diabetes duration was not associated with cognitive test performance. This indicates that diabetes is not related to lower cognitive function in the general population of non-demented old people. Diabetes, however, increases the risk for cerebrovascular incidents, like stroke, that may contribute to vascular dementia.     

In search of average growth: Describing within-year oral reading fluency growth across Grades 1–8

Measures of oral reading fluency (ORF) are perhaps the most often used assessment to monitor student progress as part of a response to intervention (RTI) model. Rates of growth in research and aim lines in practice are used to characterize student growth; in either case, growth is generally defined as linear, increasing at a constant rate. Recent research suggests ORF growth follows a nonlinear trajectory, but limitations related to the datasets used in such studies, composed of only three testing occasions, curtails their ability to examine the true functional form of ORF growth. The purpose of this study was to model within-year ORF growth using up to eight testing occasions for 1448 students in Grades 1 to 8 to assess (a) the average growth trajectory for within-year ORF growth, (b) whether students vary significantly in within-year ORF growth, and (c) the extent to which findings are consistent across grades. Results demonstrated that for Grades 1 to 7, a quadratic growth model fit better than either linear or cubic growth models, and for Grade 8, there was no substantial, stable growth. Findings suggest that the expectation for linear growth currently used in practice may be unrealistic.     

Nonlinearity in the relationship between political skill and work outcomes: Convergent evidence from three studies

The current investigation examined the form and magnitude of the relationship between political skill and two intrapersonal worker reactions—job satisfaction and job tension. Political skill was hypothesized to demonstrate an inverted U-shaped nonlinear relationship with job satisfaction and a U-shaped relationship with job tension. Data from three separate studies supported the hypothesized relationships. Specifically, moderate levels of political skill were associated with higher levels of job satisfaction (Studies 1-3) and lower levels of job tension (Studies 1 and 2). Conversely, in comparison to more moderate levels, higher and lower levels of political skill were adversely related to these outcomes. Implications, strengths and limitations, and directions for future research are discussed.
