Negativity,Finitude, and the Leap in Heidegger's Contributions to Philosophy

This article examines Heidegger's assessment of negativity and finitude in the late 1930s and his enlargement of these issues in the name of a leap from one type of philosophy, one type of beginning, to a wholly other beginning. The guiding concerns of this article are negativity, finitude and the leap, and how these overlapping concerns coalesce around Heidegger's attempts to move towards a wholly other type of philosophy; in fact, one which no longer understands itself to be philosophy at all. The article concludes with a discussion of the role of death, sacrifice, and mourning in Heidegger's thought in the 1930s.     

Predicting Change in Parenting Stress Across Early Childhood: Child and Maternal Factors

This study examined maternal parenting stress in a sample of 430 boys and girls including those at risk for externalizing behavior problems. Children and their mothers were assessed when the children were ages 2, 4, and 5. Hierarchical linear modeling (HLM) was used to examine stability of parenting stress across early childhood and to examine child and maternal factors predicting parenting stress at age 2 and changes in parenting stress across time. Results indicated that single parenthood, maternal psychopathology, child anger proneness, and child emotion dysregulation predicted 2-year parenting stress. Child externalizing behaviors predicted initial status and changes across time in parenting stress. Stability of parenting stress was dependent upon child externalizing problems, as well as interactions between child externalizing problems and gender, and child externalizing problems and emotion regulation. Results are discussed in the context of mechanisms by which parenting stress may influence the development of child externalizing behaviors.     

The cost of caring–the impact of secondary trauma on assumptions,values and beliefs

The aim of this paper is to look at the impact of working with distressed and traumatized clients. The paper describes a survey involving 430 care workers who regularly work with distressed or traumatized clients. The survey involved the participants completing a 21-item beliefs inventory describing their supervision or support and recording whether they had any spiritual or religious beliefs. A factor analysis of the results of the inventory found four factors, three of which involved the negative impact of the work on beliefs while the fourth gave an indication of the positive beliefs or post trauma growth that comes from working in this area. The results showed that while doing a good job and experiencing fulfilment were higher in carers who experienced lower levels of distressing experiences and beliefs, an increase in competence and improved learning opportunities were associated with higher levels of challenge. A review of the information provided on supervision and support showed that there was a wide variation in the sources of support for the different professions. While around 46% of the carers had spiritual beliefs only 29% were members of a religious group. The discussion looked at the implication of the results of the survey including the possible benefit of using the carer belief inventory to identify carers who may be vulnerable to secondary trauma or compassion fatigue. The need to provide support to all professions undertaking caring work with distressed or traumatized clients was highlighted.     

Interpolation processes in object perception: reply to Anderson (2007)

P. J. Kellman, P. Garrigan, & T. F. Shipley presented a theory of 3-D interpolation in object perception. Along with results from many researchers, this work supports an emerging picture of how the visual system connects separate visible fragments to form objects. In his commentary, B. L. Anderson challenges parts of that view, especially the idea of a common underlying interpolation component in modal and amodal completion (the identity hypothesis). Here the authors analyze Anderson's evidence and argue that he neither provides any reason to abandon the identity hypothesis nor offers a viable alternative theory. The authors offer demonstrations and analyses indicating that interpolated contours can appear modally despite absence of the luminance relations, occlusion geometry, and surface attachment that Anderson claims to be necessary. The authors elaborate crossing interpolations as key cases in which modal and amodal appearance must be consequences of interpolation. Finally, the authors dispute Anderson's assertion that vision researchers are misguided in using objective performance methods, and they argue that his challenges to relatability fail because contour and surface processes, as well as local and global influences, have been distinguished experimentally.     

Relations of low frustration tolerance beliefs with stress, depression, and anxiety in young adolescents

Young adolescents (N=144; 66 boys, 78 girls), ages 12 to 14 years (M=12.2, SD=.8), who reported lower scores on the Low Frustration Tolerance Beliefs Instrument had higher scores on the Perceived Stress Scale and the Profile of Mood States Subscales of Depression and Anxiety.     

Memory for emotional faces in naturally occurring dysphoria and induced sadness

The aim was to establish if the memory bias for sad faces, reported in clinically depressed patients (Gilboa-Schechtman, Erhard Weiss, & Jeczemien, 2002; Ridout, Astell, Reid, Glen, & O'Carroll, 2003) generalises to sub-clinical depression (dysphoria) and experimentally induced sadness. Study 1: dysphoric (n = 24) and non-dysphoric (n = 20) participants were presented with facial stimuli, asked to identify the emotion portrayed and then given a recognition memory test for these faces. At encoding, dysphoric participants (DP) exhibited impaired identification of sadness and neutral affect relative to the non-dysphoric group (ND). At memory testing, DP exhibited superior memory for sad faces relative to happy and neutral. They also exhibited enhanced memory for sad faces and impaired memory for happy relative to the ND. Study 2: non-depressed participants underwent a positive (n = 24) or negative (n = 24) mood induction (MI) and were assessed on the same tests as Study 1. At encoding, negative MI participants showed superior identification of sadness, relative to neutral affect and compared to the positive MI group. At memory testing, the negative MI group exhibited enhanced memory for the sad faces relative to happy or neutral and compared to the positive MI group. Conclusion: MCM bias for sad faces generalises from clinical depression to these sub-clinical affective states.     

Performance benefits and costs in forced choice perceptual identification in amnesia: Effects of prior exposure and word frequency

Accuracy in identifying a perceptually degraded word (e.g., stake) can be either enhanced by recent exposure to the same stimulus or reduced by recent exposure to a similar stimulus (e.g., stare). In the present study, we explored the mechanisms underlying these benefits and costs by examining the performance of amnesic and control groups in a forced choice perceptual identification (FCPI) task in which briefly flashed words (that were identical to studied words, similar to studied words, or new) had to be identified, and two response choices were provided that differed from each other by one letter. Control participants showed a performance benefit and cost in FCPI with both high- and low-frequency words. Amnesic participants showed a benefit (but no cost) with high-frequency words and a benefit and a cost with low-frequency words. The benefit/cost pattern with low-frequency words in amnesia was obtained even when the to-be-identified stimulus in the FCPI task was eliminated (Experiment 2), suggesting that this effect was driven by processes operating at the level of the response choices. Our findings suggest that implicit memory effects in FCPI reflect the operation of multiple mechanisms, the relative contributions of which may vary with the frequency of the test stimuli. The results also highlight the need for caution in interpreting results from normal participants in the FCPI task, since those findings may reflect a contribution of explicit memory processes.     

Is interpolation cognitively encapsulated? Measuring the effects of belief on Kanizsa shape discrimination and illusory contour formation

Contour interpolation is a perceptual process that fills-in missing edges on the basis of how surrounding edges (inducers) are spatiotemporally related. Cognitive encapsulation refers to the degree to which perceptual mechanisms act in isolation from beliefs, expectations, and utilities (Pylyshyn, 1999). Is interpolation encapsulated from belief? We addressed this question by having subjects discriminate briefly-presented, partially-visible fat and thin shapes, the edges of which either induced or did not induce illusory contours (relatable and non-relatable conditions, respectively). Half the trials in each condition incorporated task-irrelevant distractor lines, known to disrupt the filling-in of contours. Half of the observers were told that the visible parts of the shape belonged to a single thing (group strategy); the other half were told that the visible parts were disconnected (ungroup strategy). It was found that distractor lines strongly impaired performance in the relatable condition, but minimally in the non-relatable condition; that strategy did not alter the effects of the distractor lines for either the relatable or non-relatable stimuli; and that cognitively grouping relatable fragments improved performance whereas cognitively grouping non-relatable fragments did not. These results suggest that (1) filling-in effects during illusory contour formation cannot be easily removed via strategy; (2) filling-in effects cannot be easily manufactured from stimuli that fail to elicit interpolation; and (3) actively grouping fragments can readily improve discrimination performance, but only when those fragments form interpolated contours. Taken together, these findings indicate that discriminating filled-in shapes depends on strategy but the filling-in process itself may be encapsulated from belief.
