Pavlovian processes and response competition as determinants of avoidance response-prevention effects

Two experiments investigated the facilitation of avoidance extinction by exposure to lengthy (5-sec) shock during avoidance response prevention. In Experiment 1, animals exposed to light only or to light-shock pairings during response prevention showed equal facilitation of extinction relative to shock-only animals or to animals receiving no response prevention. Preshock rearing, directly antagonistic to the avoidance response, developed for shocked animals during response prevention and persisted during extinction for light-shock animals. Immediately before extinction, half of each group was permitted a single escape from a light-shock compound by means of the response previously required for avoidance. The only effect was upon the extinction performance of light-shock animals. Rearing was eliminated and extinction responding increased to a level far above that for any of the other animals. Experiment 2 demonstrated that the shock-only treatment affected the extinction performance and rearing of nonescape and escape animals in a manner entirely equivalent to the effects of the light-shock treatment of Experiment 1, provided stimulus conditions (light absent) were the same for all experimental phases. Thus, lengthy shock during avoidance response prevention simultaneously leads to the acquisition of competing behavior and enhances control by a warning signal or contextual stimuli over the avoidance response. Implications for the CS-only response-prevention treatment and the transfer of aversive control are discussed.     

Lutheran Preaching and the Quest for Humanization and Planetary Justice: A Perspective from Brazil

Abstract :  Since economic globalization hides the roots of injustice and internationalizes its consequences, any attempt to preach (which necessarily means to preach justice) must address the local church and at the same time the wider global context, hence the term "planetary justice." This article describes the current approach to Lutheran preaching in Latin America and specifically the Evangelical Lutheran Church in Brazil (IECLB). The article offers the following suggestions for Lutheran preaching throughout the world: hold form and content in creative tension; present justification as liberation; strive for a biocentric, gender conscious, and planetary symbiotic homiletic.     

Inclusiveness of identification among farmers in The Netherlands and Galicia (Spain)

In this paper we discuss inclusiveness of identification among farmers in Galicia (Spain) and The Netherlands. Identification with three nested categories—farmers in the local community, farmers in the country, and farmers in Europe was assessed among 167 Dutch and 248 Galician farmers at three points in time: winter of 1993/94, winter 1995 and fall 1995. Our findings suggest that inclusiveness reduces the level of identification. However, the observed patterns of identification were more complex than inclusiveness per se can account for. Borrowing from the common ingroup‐identity model, functional and socialization models of identity formation, and a model of politicized collective identity we formulated hypotheses about patterns of identification that were to be expected. On the whole our findings supported our theoretical reasoning. Galician farmers appear to identify much less with farmers in their country and Europe than Dutch farmers do. Inclusiveness of identification appears to be linked to experience with national and supranational political institutions. More political knowledge and involvement appear to generate more inclusive patterns of identification. Among Galician farmers evaluation of the agricultural policy of the European Union is negatively related to identification with farmers in Europe, among Dutch farmers the two are positively related. Finally, more inclusive identities seem to be more politicized. Copyright © 2004 John Wiley & Sons, Ltd.     

WITTGENSTEIN'S PERSONALITY AND HIS RELATIONS WITH FREUD'S THOUGHT

In this contribution the author examines the connections between Wittgenstein's personality and his attitude to Freud's psychoanalytic theories in the light of biographies of the philosopher, published exchanges of letters between him and his sisters, his 'secret' diaries from the time of the First World War, his diaries from the nineteen-thirties and the writings in which he discusses Freud and psychoanalysis. The paper quotes liberally from all these sources. Following an account of Wittgenstein's cultural and family background in Vienna and his subsequent peripatetic life, hypotheses are presented concerning his personality, sexuality and 'internal' theology, together with some ideas about his relationship with his family (in particular, his parents and sisters) and his critique of Freud's theories, with particular reference to dreams and their interpretation. Wittgenstein emerges as a highly original philosopher who is, however, emotionally disturbed and restless. His personality is found to have narcissistic aspects that moulded his behaviour and thought, and the author contends that his mental suffering caused him to apply psychological and psychoanalytic categories to his philosophy.     

The effects of intention and practice on a non-motor duration estimation task

It has already been shown that the intention to reproduce a motor task in the future improves its learning. Here, we tested whether intention had a similar effect on learning to perform a non-motor duration estimation task, and if intention interacted with the amount of practice. Participants learned to estimate and compare two different durations, with or without intending to reproduce this learning in the future, and with two different amounts of practice. The results showed that intention and practice enhanced task learning independently. Moreover, only practice enhanced learning in over-estimation strategy. These finding are discussed with respect to a possible mechanism by which intention and practice might improve the learning of a duration task.     

Am I guilty or not? Deontological guilt,uncertainty, and checking behavior

Literature suggests that checking behaviors are aimed at reducing feelings of uncertainty both in clinical samples with obsessive‐compulsive disorder and in general population. Previous studies also showed that deontological guilt is an emotion often associated with obsessive‐compulsive disorder. Thus, the aim of the current study was to investigate the differences in checking behaviors in the condition of high versus low uncertainty, by exploring the moderating role of deontological versus altruistic guilt. Participants were 108 undergraduate Italian university students who took part in a visual search task designed to elicit checking behavior. Ahead of the visual task, participants were administered one scenario in order to manipulate either deontological or altruistic guilt. The results showed that in the condition of uncertainty, compared with the condition of certainty, participants spent more time in checking behaviors and that such a difference was more consistent when participants experienced deontological rather than altruistic guilt. Limitations and further directions are discussed.     

Promoting foot–leg movements in children with multiple disabilities through the use of support devices and technology for regulating contingent stimulation

The present study assessed the possibility of promoting pre-ambulatory foot–leg movements in children with multiple disabilities by motivating their action through contingent stimulation combined with a support device. Two children aged 10 and 8 years participated. Microswitch technology (i.e., pressure sensors under the shoes or optic sensors at the front–inner side of the shoes) served for detecting the foot–leg movements and providing contingent stimulation on their occurrence. Sensor activation produced 5 s of stimulation during intervention. Data showed that both children had significant increases in foot–leg movements during the intervention phases. Implications of the data in terms of skill acquisition and further intervention prospects are discussed.     

Gastroesophageal reflux disease: alexithymia and attachment style

Alexithymia and its relation with attachment style were evaluated in a group of 69 patients (men, M age = 46.4 yr., SD = 12.6; women, M age = 44.2 yr., SD = 14.4) affected by Gastroesophageal Reflux Disease. Two self-evaluation questionnaires were used for psychological evaluation, the 20 item Toronto Alexithymia Scale (TAS-20) and the Attachment Style Questionnaire (ASQ). The TAS-20 analysis showed that the clinical sample taken as a whole did not score in the alexithymic range. The inverse correlations between the Confidence ASQ subscale and the Difficulty Communicating Feelings TAS-20 subscale showed that communication of emotions could develop more easily within the framework of a relational context characterized by safety and confidence. In this group of patients this was represented by the referent caregiver.     

At the root of embodied cognition: cognitive science meets neurophysiology

Recent experimental research in the field of neurophysiology has led to the discovery of two classes of visuomotor neurons: canonical neurons and mirror neurons. In light of these studies, we propose here an overview of two classical themes in the cognitive science panorama: James Gibson's theory of affordances and Eleanor Rosch's principles of categorization. We discuss how theoretical perspectives and neuroscientific evidence are converging towards the current paradigm of embodied cognition. From this perspective, we discuss the role of action and simulation in cognitive processes, which lead to the perceptual recognition of objects, and actions and to their conceptual categorization.     

Numerosity-duration interference: a Stroop experiment

The existence of a possible common mechanism for duration and numerosity processing was tested with a Stroop task. Participants had to compare either the duration or the numerosity of sequences of flashing dots for which the duration and numerosity were independently manipulated to create congruent, incongruent or neutral pairs. Results show that the numerical cues interfered with duration processing, whereas the temporal cues did not interfere with numerosity processing. These findings extend the idea of an automatic access to magnitude to non-symbolic sequentially presented material, and reflect a probable difference in the mandatory processing of numerosity and duration.
