Les apports de la psychologie sociale aux situations de formation par alternance

This article aims to show how the alternating trainings have been treated by researchers using social psychology approaches. It identifies the theoretical models used, the main researches and some of their results. It comes to the idea that psychology appears as an essential discipline to understand the evolutions of the individuals in these work and training situations but it not sufficiently used. Then, some topics for future researches are designed. The alternating training appears as a very rich situation which allows to understand the individual as well as organizational transformations and the different levels of interrelations of the individual with his/her environment.     

Integrating conceptual knowledge within and across representational modalities

Research suggests that concepts are distributed across brain regions specialized for processing information from different sensorimotor modalities. Multimodal semantic models fall into one of two broad classes differentiated by the assumed hierarchy of convergence zones over which information is integrated. In shallow models, communication within- and between-modality is accomplished using either direct connectivity, or a central semantic hub. In deep models, modalities are connected via cascading integration sites with successively wider receptive fields. Four experiments provide the first direct behavioral tests of these models using speeded tasks involving feature inference and concept activation. Shallow models predict no within-modal versus cross-modal difference in either task, whereas deep models predict a within-modal advantage for feature inference, but a cross-modal advantage for concept activation. Experiments 1 and 2 used relatedness judgments to tap participants’ knowledge of relations for within- and cross-modal feature pairs. Experiments 3 and 4 used a dual-feature verification task. The pattern of decision latencies across Experiments 1–4 is consistent with a deep integration hierarchy.     

Effects of syllable structure in aphasic errors: implications for a new model of speech production

Current models of word production assume that words are stored as linear sequences of phonemes which are structured into syllables only at the moment of production. This is because syllable structure is always recoverable from the sequence of phonemes. In contrast, we present theoretical and empirical evidence that syllable structure is lexically represented. Storing syllable structure would have the advantage of making representations more stable and resistant to damage. On the other hand, re-syllabifications affect only a minimal part of phonological representations and occur only in some languages and depending on speech register. Evidence for these claims comes from analyses of aphasic errors which not only respect phonotactic constraints, but also avoid transformations which move the syllabic structure of the word further away from the original structure, even when equating for segmental complexity. This is true across tasks, types of errors, and, crucially, types of patients. The same syllabic effects are shown by apraxic patients and by phonological patients who have more central difficulties in retrieving phonological representations. If syllable structure was only computed after phoneme retrieval, it would have no way to influence the errors of phonological patients. Our results have implications for psycholinguistic and computational models of language as well as for clinical and educational practices.     

Spreading Activation in an Attractor Network With Latching Dynamics: Automatic Semantic Priming Revisited

Localist models of spreading activation (SA) and models assuming distributed representations offer very different takes on semantic priming, a widely investigated paradigm in word recognition and semantic memory research. In this study, we implemented SA in an attractor neural network model with distributed representations and created a unified framework for the two approaches. Our models assume a synaptic depression mechanism leading to autonomous transitions between encoded memory patterns (latching dynamics), which account for the major characteristics of automatic semantic priming in humans. Using computer simulations, we demonstrated how findings that challenged attractor‐based networks in the past, such as mediated and asymmetric priming, are a natural consequence of our present model’s dynamics. Puzzling results regarding backward priming were also given a straightforward explanation. In addition, the current model addresses some of the differences between semantic and associative relatedness and explains how these differences interact with stimulus onset asynchrony in priming experiments.     

The Social Representations of the Bali Climate Conference in the French and German Media

Climate change is a major current affair for which recent United Nations climate conferences aim to build consensus and develop international solutions. The objective of this article is to compare, through the theoretical lens of social representations, the way in which French and German media, specifically newspapers, represent the Bali climate conference. We use the triangulation of data analysis to take both the pragmatic and the semantic aspects of media discourse into account. Results show that German media adopt both a local and a global vision of climate change and of the conference. Religious metaphors highlight a moral dimension of the conference, suggesting anchoring in human and political categories. In contrast, in French media, we identify that conflicts between countries render the stakes of climate change concrete by war metaphors. The French discourses examined are shown to be organised through the anchoring of political and financial categories. Results are discussed in relation to the history of green movements in the two countries and in relation to practical implications. Copyright © 2011 John Wiley & Sons, Ltd.     

意外地点任务中不同测试问题及意图理解与执行功能的关系

旨在讨论意外地点任务中“知否问题”与“预测问题”可能存在的差异及两者与执行功能任务的关系,并初步探讨意图理解与执行功能间的关系。用意外地点任务、膝跳反射任务和两个执行功能的任务（DCCS和手部游戏）对59名3~5岁的儿童施测。结果显示：（1）儿童在意外地点任务的“知否问题”上的表现显著好于“预测问题”,儿童对“知否问题”和“预测问题”的回答可能反映了心理理论发展的不同阶段。（2）膝跳反射任务,DCCS任务与“知否问题”三者间有显著的相关,且其高相关在排除年龄及语言能力的影响后仍保持显著。“双表征区分结构”可能是三者间具有共同的成分。     

Applying social psychology to the study of environmental concern and environmental worldviews: contributions from the social representations approach

Recently some social psychological approaches have intensified their contributions to research in the environmental domain, helping it to focus more consistently on the shared aspects of all environment related experiences. The goal of this paper is that of joining these efforts, exploring the contributions of the social representations approach to research on environmental concern and environmental thought, as another area for applying social psychological knowledge. The paper first sketches how the environmental concern of the publics emerged in the 70s as a problem for the social sciences and proceeds to summarizing the main characteristics of this research, focusing on three problematic areas: (1) incipient theoretical integration among the frameworks dominating research; (2) insufficient reflection about the assumptions and measurement of the concepts employed; (3) a need for new research questions that push studies beyond the analysis of the socio‐demographical correlates of beliefs. Afterwards a presentation of social representations theory will be undertaken and the usefulness of the approach to deal with some aspects of the problematic areas identified will be explored, with examples from recent research, and highlighting the importance of focusing on contradiction, polyphasia, and the articulation of the local and the global.

儿童对图画兴趣和表征发展差异的跨文化研究

本实验是一项跨文化的比较研究 ,旨在探索儿童对图画兴趣的动态变化及表征的发展。被试年龄跨度为 4岁至成人 ,均未受过美术训练。通过他们各自根据线条画中所含的颜色或主题或情绪的特性匹配的特点 ,来发现内在的规律。实验发现年幼儿童以颜色为匹配标准 ,年长儿童和成人则以主题或情绪为主。中国儿童比英国儿童对图画中的语义联系 (表达的情绪 )更敏感。在主题 /情绪匹配中 ,中国 1 0岁儿童和成人都侧重情绪特征 ,而英国儿童随年龄发展由主题特性转向情绪特性这一兴趣的发展趋势并不明显。本文从美学的角度应用当代有关图画表征发展的理论对实验进行了分析 ,探讨了在中英不同文化背景下影响儿童兴趣变化及表征能力发展的因素。     

Multi-Encoding for Pitch Information of Tone Sequences

This study was designed to investigate the possibilities that subjects would visualize an auditory contour as a visual contour (visual imagery) to encode pitch information of tone sequences (Experiment 1), and that subjects would be motivated to attempt to engage in covert rehearsal with multi-code (Experiment 2). The findings from these experiments suggest that: (a) Whereas the highly musically trained subjects were able to encode pitches as accurate notes on a staff, the less well musically trained subjects encoded the pitch sequence as a contour. It is quite evident that there is an intermodal analogy between the perception of pitch relationships and that of relationships in visual space. (b) Pitch rehearsal of auditory information along with note names (dual-code) and staff notation accompanied by pitch rehearsal with note names (triple-code) were the most effective strategies for highly trained subjects with pitches of tonal sequences; melodic contour accompanied by pitch rehearsal (dual-code) was used by highly trained subjects with atonal sequences and by less well trained subjects with both types of sequences.
