Variations in size judgements as a function of surface texture

Adult subjects made monocular size judgements in two experiments in which the independent variables of surface texture and restrictions on viewing conditions were manipulated. Texture density gradients of stimulation had a significant influence of size judgements only under the less reduced conditions of observation when subjects could see other textured surfaces beyond the surfaces over which judgements were made. Identical manipulations of surface texture had earlier been found to have a highly significant influence on relative distance judgements (Newman, 1971). The principally negative results were thus taken to imply that subjects extract different information from the texture density gradient when judging size from that extracted when judging relative distance.     

Psychoanalytic supervision and the larger truth

If one asks, then, what is the larger truth in supervision and where is it to be found, the answer is that it is to be found in the history and character of the student; in the intersubjective encounter between the student and the supervisor; in the secret use of supervision by the student as he creatively searches for himself. However one chooses to define truth or to speak to a theory of supervision, it is important to note that supervision is not purely an educational activity nor a therapeutic one. It lies somewhere in between and therefore requires some unique theoretical formulations.     

Endogenous attention modulates early selective attention in psychopathy: An ERP investigation

Psychopathic individuals are prone to act on urges without adequate consideration of future consequences or the rights of other individuals. One interpretation of this behavior is that it reflects abnormal selective attention (i.e., a failure to process information that is incongruent with their primary focus of attention; Hiatt, Schmitt, & Newman, Neuropsychology, 18, 50-59, 2004). Unfortunately, it is unclear whether this selective attention abnormality reflects top-down endogenous influences, such as the strength or specificity of attention focus (i.e., top-down set) apart from other, more exogenous (bottom-up), effects on attention. To explore this question, we used an early visual event-related potential (N2pc) in combination with a modified visual search task designed to assess the effect of early endogenous (i.e., top-down) attention on the processing of set-congruent information. The task was administered to a sample of 70 incarcerated adult males, who were assigned to high, intermediate, and low psychopathy groups using Hare’s Psychopathy Checklist-Revised (Hare, 2003). Based on the assumption that their failure to process set-incongruent information reflects the exaggerated effects of endogenous attention, we predicted that participants with high psychopathy scores would show an exaggerated N2pc response to set-congruent information. The results supported the hypothesis and provide novel electrophysiological evidence that psychopathy is associated with exaggerated endogenous attention effects during early stages of processing. Further research is needed to examine the implications of this finding for the well-established failure of psychopathic individuals to process set-incongruent information and inhibit inappropriate responses.     

Leisure and Subjective Well-Being: A Model of Psychological Mechanisms as Mediating Factors

Leisure is a key life domain and a core ingredient for overall well-being. Yet, within positive psychology, its definition and the psychological pathways by which it evokes happiness are elusive (Diener and Biswas-Diener 2008). In this paper, we seek to address these issues by delineating leisure and presenting a conceptual framework linking leisure to subjective well-being (SWB). Leisure is defined as a multidimensional construct, encompassing both structural and subjective aspects. Respectively, it is the amount of activity/time spent outside of obligated work time and/or perceived engagement in leisure as subjectively defined. To explain the effects of leisure on SWB, a quantitative summary of theories from 363 research articles linking leisure and SWB was conducted. Based on our findings, we propose five core psychological mechanisms that leisure potentially triggers to promote leisure SWB: detachment-recovery, autonomy, mastery, meaning, and affiliation (DRAMMA). These psychological mechanisms promote leisure SWB which leads to enhanced global SWB through a bottom-up theory of SWB. We discuss how future research can use this conceptual model for understanding the interplay between leisure and SWB.     

Locke on the Idea of Substratum

Locke's treatment of substratum is notoriously difficult. Accordingto one commentator, 'nothing else in the writings of any philosopher matches the doubleness of attitude of the passages about substratum in Locke's Essay' (Bennett 1987, 197). The aim of the present paper is to render consistent Locke's seemingly divergent strands on the subject. My efforts are organized around three levels of apparent duplicity. At each level, I argue that the doubleness of attitude in Locke's treatment is merely apparent. I argue further that Locke means to ground an empiricist-friendly idea of substratum in the customary experience of simple ideas that 'go constantly together.'     

Psychosocial outcomes in later life: a multivariate model

A conceptual model was developed to identify developmental self-regulatory pathways to optimal psychosocial outcomes in adulthood. The model delineates influences among age, possible selves, developmental processes (i.e., coping, control), and well-being. Results showed age effects on all constructs except selective control. Three consistently common predictors of well-being (i.e., goal pursuit, goal adjustment, and optimization) emerged. The effects of age on well-being were differentially mediated by developmental processes. Specifically, negative age-related changes in offensive processes (i.e., goal attainment) were offset by positive influences of defensive processes (i.e., goal adjustment), which had the net effect of preserving well-being. The model demonstrates a more optimistic pattern of aging in which gains offset losses leading to positive outcomes and highlights the importance of examining both independent and combined influences of age, self, and developmental processes on psychosocial outcomes.     

Hemisphere differences and judgments of simultaneity of brief light flashes

A series of experiments was conducted to investigate the possibility of hemispheric specialization for judgments of the simultaneity of two light flashes. Right-handed subjects adjusted two light flashes until they appeared simultaneous. The comparison of measures derived from the two possible orders of the light flashes suggested that the right hemisphere of right-handed subjects performed the function of ordering visual stimuli in time. Two further experiments examined an alternative explanation, that of a left-to-right scanning mechanism, the results of which also suggested a hemisphere explanation. The results of these experiments are discussed in terms of previous research and theories which located a temporal ordering mechanism in the speech hemisphere.
