Situational and dispositional coping: an examination of their relation to personality,cognitive appraisals,and psychological distress

Reliable data on the relationships between situational and dispositional coping strategies are sparse. In order to address this gap in the literature, this study examined the determinants and adaptational outcomes of both types of coping. Two hundred and thirty‐three students completed, along with measures of situational and dispositional coping, measures of personality, cognitive appraisals, and psychological distress, the latter variable being evaluated concurrently and prospectively (10 weeks). Results showed that personality shared as much variance with situational as with dispositional coping, but the patterns of relationships were rather different. In addition, cognitive appraisals were found to add significant incremental validity in predicting situational coping beyond trait coping, but primary appraisals were redundant with personality traits, in particular neuroticism. Finally, in spite of the significant amount of variance shared between the two types of coping, they both accounted for individual differences in concomitant and prospective psychological distress, and the relation between dispositional coping and distress was partially mediated by situational coping. The implications of these findings for understanding the relationships between the two types of coping strategy are discussed. Copyright © 2004 John Wiley & Sons, Ltd.     

The contents of long-term memory and the emergence of knowledge

Through a review of the literature, this paper proposes arguments in favour of a multimodal, dynamic, functional, and situational conception of memory. Memory is assumed to contain traces that reflect past experiences. The properties of these experiences are considered to be distributed across multiple neuronal systems, which are responsible, in particular, for sensorimotor and emotional processing. Memory is dynamic because knowledge emerges almost continuously from the activation and integration of these multimodal components. Memory is functional and situational because knowledge emerges from the subject's activity in a given situation, that is from a type of resonance between the properties of the past experiences that have shaped the neuronal networks and the properties of present experiences.     

Enhancing the mental representations of space used by blind pedestrians, based on an image schemata model

The configuration of mental representation of space plays a major role in successful navigational activities. Therefore, navigational assistance for pedestrians who are blind should help them to better configure their mental representation of the environment. In this paper, we propose and exploit a computational model for the mental representation of urban areas as an aid to orientation and navigation for visually impaired pedestrians. Our model uses image schemata to capture the spatial semantics and configural elements of urban space necessary for this purpose. These image schemata are schematic structures that are continually requested by individuals in their perception, bodily movement and interaction with surrounding objects. Our proposed model also incorporates a hierarchical structure to provide different levels of detail tied to appropriate spatial perspectives at each scale. We presume that such computational model will help us to develop an appropriate structure of spatial data used to assist the target population. At the end of the paper, we illustrate the utility of our configural model by developing a typical scenario for the navigation of a blind pedestrian in an urban area.     

Activation and integration of motor components in a short-term priming paradigm

The aim of the present research was to study the processes involved in knowledge emergence. In a short-term priming paradigm, participants had to categorize pictures of objects as either "kitchen objects" or "do-it-yourself tools". The primes and targets represented objects belonging to either the same semantic category or different categories (object category similarity), and their use involved gestures that were either similar or very different (gesture similarity). The condition with a SOA of 100ms revealed additive effects of motor similarity and object category similarity, whereas another condition with a SOA of 300ms showed an interaction between motor and category similarity. These results were interpreted in terms of the activation and integration processes involved in the emergence of mental representations.
