Immediate early gene activation in hippocampus and dorsal striatum: effects of explicit place and response training

Evidence from lesion, electrophysiological, and neuroimaging studies support the hypothesis that the hippocampus and dorsal striatum process afferent inputs in such a way that each structure regulates expression of different behaviors in learning and memory. The present study sought to determine whether rats explicitly trained to perform one of two different learning strategies, spatial or response, would display disparate immediate early gene activation in hippocampus and striatum. c-Fos and Zif268 immunoreactivity (IR) was measured in both hippocampus and striatum 30 or 90 min following criterial performance on a standard plus-maze task (place learners) or a modified T-maze task (response learners). Place and response learning differentially affected c-Fos-IR in striatum but not hippocampus. Specifically, explicit response learning induced greater c-Fos-IR activation in two subregions of the dorsal striatum. This increased c-Fos-IR was dependent upon the number of trials performed prior to reaching behavioral criterion and accuracy of performance during post-testing probe trials. Quantification of Zif268-IR in both hippocampus and striatum failed to distinguish between place and response learners. The changes in c-Fos-IR occurred 30 min, but not 90 min, post-testing. The synthesis of c-Fos early in testing could reflect the recruitment of key structures in learning. Consequently, animals that were able to learn the response task efficiently displayed greater amounts of c-Fos-IR in dorsal striatum.     

Knowledge of place and knowledge of God: contemporary philosophies of place and some questions in philosophical theology

The paper examines three themes from the recent philosophical literature on place: the status of places as “concrete universals”; the narratively mediated agency of places; and the various ways in which human identity proves to be relative to place. I argue that these themes throw into new relief a set of correlative issues in philosophical theology concerning, respectively, God’s supra-individuality, God’s status as a final cause, and the divine grounding of human identity. On this basis, the paper proposes that knowledge of place is analogous to, and partly constitutive of, knowledge of God.     

Socio-cultural invisibility and belonging: Latin American migrants in the north of England

This paper explores the multiple and simultaneous senses of belonging of Latin Americans in the north of England, a sparse migrant population characterised by a high degree of socio-cultural invisibility, i.e. lack of official recognition and limited cultural/ethnic organisation. It draws on a project conducted with 10 Latin American and Latino British families (totalling 30 adults and dependent children of 8–18 years of age) and 14 other informants and stakeholders in the Yorkshire and Greater Manchester regions. The paper analyses the senses of everyday belonging of the adult participants and the role that conditions of socio-cultural invisibility play in their experiences. Significant here are the lack of ethno-cultural local spaces and reluctance to embrace pan-ethnic identifications, which bring to the fore the relevance of other local social contexts and of transnational ties as sites of everyday belonging. It is argued that by paying attention to the emotions and emotional compromises that constitute migrants' senses of belonging, it is possible to develop nuanced insights into the diversity of ways in which migrants experience processes of incorporation and combine bonds to sending and receiving societies.     

Accompagner et instrumenter l’intervention dans une organisation en transition (SCOP) : quand l’intervenant doit prendre et trouver sa place

Our contribution is based on the observation in immersion of a collective of workers engaged in the struggle to take back its factory in Scop. We seek to understand, from the analysis of this intervention, what is the place and the role that the psychologist of work takes or is given in this context of transformation. From this perspective, the use of the intervention method has produced a large body of data that we have chosen to analyze according to the job four-dimensional model (Clot, 2008). We seek then to make visible our slippages in the use of this method, the interferences that may be the cause, the way in which they affect us, and what we can make of it. As we believe that these affects, however uncomfortable, can be transformed into objects of analysis to the benefit of the collective and its current activity.     

Like a Fish Out of Water: Reconsidering Disaster Recovery and the Role of Place and Social Capital in Community Disaster Resilience

In this paper we draw on the findings of a critical, multi-sited ethnographic study of two rural communities affected by a wildfire in British Columbia, Canada to examine the salience of place, identity, and social capital to the disaster recovery process and community disaster resilience. We argue that a reconfiguration of disaster recovery is required that more meaningfully considers the role of place in the disaster recovery process and opens up the space for a more reflective and intentional consideration of the disorientation and disruption associated with disasters and our organized response to that disorientation. We describe a social-psychological process, reorientation, in which affected individuals and communities navigate the psychological, social and emotional responses to the symbolic and material changes to social and geographic place that result from the fire's destruction. The reorientation process emphasizes the critical importance of place not only as an orienting framework in recovery but also as the ground upon which social capital and community disaster resilience are built. This approach to understanding and responding to the disorientation of disasters has implications for community psychologists and other service providers engaged in supporting disaster survivors. This includes the need to consider the complex dynamic of contextual and cultural factors that influence the disaster recovery process.     

Why versus how often: Causal reasoning and the incidence of judgmental bias

When faced with the task of making a prediction or estimating a likelihood, it is argued that people often reason about the presence or absence and relative strength of possible causal mechanisms for the production of relevant outcomes. In so doing people rely on “causal cues” or properties of an inferential problem which indicate the nature of the particular causal processes which give rise to specific outcomes. It is hypothesized that causal cues, precisely because they focus attention and thought on specific causal mechanisms, can obscure the relevance of mathematical laws of probability and lead to statistically biased judgment. Two experiments were conducted. Their results support the hypothesis, showing that the incidence of the conjunction fallacy and the base rate fallacy depend on task-specific cues for causal reasoning.     

The ambiguity of recognition memory tests of schema theories

The majority of theories about the effects of schemata (or generic knowledge structures) on information processing share two fundamental assumptions. It is assumed, first, that schema-based inferences about unobserved features of an event are generated, and, second, that such inferences are stored in long-term memory and thereby confused with traces of observed features of that event. To test these assumptions, researchers rely heavily on recognition memory measures of hit and false alarm rates. In the present paper, it is observed that schema theoretic interpretations of recognition memory measures are inconsistent with an interpretation jointly derived from the theory of signal detection and Mandler's (1980, Psychological Review, 87, 252–271) subjective familiarity theory of recognition memory; from the latter's perspective, recognition memory measures are considerably more ambiguous than schema researchers realize and do not necessarily support the typical schema theoretic interpretations. Data from four experiments are analyzed from the perspective of the theory of signal detection/ subjective familiarity model and demonstrate the ambiguity of recognition memory measures for testing hypotheses about the function and consequences of schemata for information processing.     

Career stage as a moderator of performance relationships with facets of job satisfaction and role perceptions

The relationship between performance indices and facets of job satisfaction, role ambiguity, and role conflict was studied among 102 full-time faculty members across three career stages. Results indicate that an individual's career stage within a profession has an important moderating effect on facets of job satisfaction and role perception relationships with role-related performance.     

Finite and infinite state confusion models

A confusion model is defined as a model that decomposes response probabilities in stimulus identification experiments into perceptual parameters and response parameters. Historically, confusion models fall into two groups. Models in Group I, which includes Townsend's (Perception and Psychophysics, 1971, 9, 40–50) overlap model, were developed on the basis of the notion that stimulus identification is mediated by a finite number of internal states. We call the general class of models that have this processing interpretation finite state confusion models. Models in Group II, which includes Luce's (R. O. Luce et al., Eds., Handbook of Mathematical Psychology (Vol. I), New York: Wiley, 1963) biased choice model, were not developed on the basis of an explicit processing interpretation. It is shown here that models in Group II are not finite state confusion models. We prove in addition that except for Falmagne's (Journal of Mathematical Psychology, 1972, 9, 206–224) simply biased model models in Group II belong to a certain class of infinite state confusion models, namely, models asserting that stimulus identification is mediated by a continuous space of vectors representing detector activation levels.     

AN EVALUATION OF TEACHING-FAMILY (ACHIEVEMENT PLACE) GROUP HOMES FOR JUVENILE OFFENDERS

Juvenile crime is a serious problem for which no treatment approach has been found to be reliably effective. This outcome evaluation assessed during and posttreatment effectiveness of Teaching-Family group home treatment programs for juvenile offenders. The evaluation included the original Achievement Place program, which was the prototype for the development of the Teaching-Family treatment approach, 12 replications of Achievement Place, and 9 comparison group home programs. Primary dependent measures were retrieved from court and police files and included number of alleged offenses, percentage of youths involved in those alleged offenses, and percentage of youths institutionalized. Other dependent measures were subjective ratings of effectiveness obtained from the program consumers, including the group home residents. The results showed difference during treatment favoring the Teaching-Family programs on rate of alleged criminal offenses, percentage of youths involved in those offenses, and consumer ratings of the programs. The consumer ratings provided by the youths and their school teachers were found to be inversely and significantly correlated with the reduction of criminal offenses during treatment. There were no significant differences during treatment on measures of noncriminal offenses (e.g., truancy, runaway, and curfew violations). In the posttreatment year, none of the differences between the groups was significant on any of the outcome measures. The results are discussed in terms of measurement and design issues in the evaluation of delinquency treatment programs and in relation to the evaluation of Teaching-Family group homes by Richard Jones and his colleagues.
