Contributions of Community Psychology to Rural Advisory Services: An Analysis of Latin American Rural Extensionists’ Point of View 下载免费PDF全文
Fernando Landini 《American journal of community psychology》2015,55(3-4):359-368
During the last decade, rural extension has received interest as being a key tool for rural development. Despite rural extension being affected by many psychosocial processes, psychology has made scarce contributions to it. An investigation was conducted with the aim of gaining knowledge of rural extensionists’ expectations of psychology, as well as to contribute to shaping community psychologists’ role in the context of rural extension . 652 extensionists from 12 Latin American countries were surveyed. The survey included closed socio‐demographic questions as well as open ones addressing extension practice and psychologists’ potential contributions. 90.6 % of surveyed extensionists considered psychology could help them improve their practice. Most mentioned areas of contribution go in line with community psychology, including managing farmers groups, facilitating participatory processes and training extensionists; while others, such as the expectation of changing farmers’ mindset and increasing the adoption of external technologies, go against its principles. Thus, in some cases, extensionists’ expectations could help generate an interesting interaction between community psychology and rural extension, while in others, they need to be put up for discussion. In brief, community psychology has the potential to contribute to rural extension, but it needs to acknowledge extension practice as an interesting area for intervention. 相似文献

Recent studies have reported an intricate interplay between affordance and mirror effects (the imitation of another agent) when participants attend to the concurrent presentation of an object and another agent interacting with it. In the present paper, we compare two experimental settings in which an observed action was presented as a prime for a task involving the categorization of a graspable object. In experiment 1a, the action depicted a reach and grasp gesture whereas in experiment 1b, only the reach phase was presented. This modification led to very different outcomes. Experiment 1a reflected the traditional imitation effect elicited by human motion. Conversely, experiment 1b showed the facilitation of contralateral responses. Affordance effects were found in experiment 1a only for the RVF. Our results support the view that motor simulation processes underlying imitation or joint actions are extremely sensitive to specific phase kinematics. 相似文献

This article offers an entirely new way of addressing middle age or mid‐life. It uses the neologism maturescence to denote this process's metapsychological feature, and it proposes a meta‐psychology of maturescence in order to allow a ‘direct understanding of maturescence’ instead of the ‘indirect understanding of maturescence’, which psychoanalytic literature generally alludes to. The paper examines somatic processes specific to male and female climacterics and is focused on to the tension between the soma and the body. It examines the drive increase that Freud posed in climacterics and the somatic climacteric imbalance that begets specific drive activity demanding psychic work, with very different pathways depending on the individual's specific working‐through activity. It discusses what happens to the individual when he/she is no longer able to procreate and begins to age; why this process is equivalent for individuals who had children and for others who could not or did not. This somatic event provides a universal constant from which it is possible to understand any individual variable. 相似文献

Several studies have illuminated how processing manual action verbs (MaVs) affects the programming or execution of concurrent hand movements. Here, to circumvent key confounds in extant designs, we conducted the first assessment of motor–language integration during handwriting—a task in which linguistic and motoric processes are co‐substantiated. Participants copied MaVs, non‐manual action verbs, and non‐action verbs as we collected measures of motor programming and motor execution. Programming latencies were similar across conditions, but execution was faster for MaVs than for the other categories, regardless of whether word meanings were accessed implicitly or explicitly. In line with the Hand‐Action‐Network Dynamic Language Embodiment (HANDLE) model, such findings suggest that effector‐congruent verbs can prime manual movements even during highly automatized tasks in which motoric and verbal processes are naturally intertwined. Our paradigm opens new avenues for fine‐grained explorations of embodied language processes. 相似文献

The main determinants of lexical access in speech are considered to be a word's age of acquisition (AoA) and its frequency of occurrence in a speaker's experience. It is unclear whether and how these variables interact, although they are commonly observed to be correlated, for the few studies that address the issue have reported inconsistent findings. An influential view of AoA in lexical processing (Ellis and Lambon Ralph, 2000) predicts stronger frequency effects for items acquired later in life than for those acquired at an early age. Five experiments were designed to investigate the possible interaction of AoA and frequency effects in speech. We found that the interaction between word frequency and AoA was not robust and that, contrary to expectation, the effect of word frequency was greater for words acquired earlier in life than for those acquired later. The implications of our findings are discussed. 相似文献

We do not know how vocal learning came to be, but it is such a salient trait in human evolution that many have tried to imagine it. In primates this is difficult because we are the only species known to possess this skill. Songbirds provide a richer and independent set of data. I use comparative data and ask broad questions: How does vocal learning emerge during ontogeny? In what contexts? What are its benefits? How did it evolve from unlearned vocal signals? How was brain anatomy altered to enable vocal learning? What is the relation of vocal learning to adult neurogenesis? No one has described yet a circuit or set of circuits that can master vocal learning, but this knowledge may soon be within reach. Moreover, as we uncover how birds encode their learned song, we may also come closer to understanding how we encode our thoughts. 相似文献

We appreciate the thoughtful responses we have received on ‘Disclosing New Worlds’. We will respond to the concerns raised by grouping them under three general themes. First, a number of questions arise from lack of clarity about how the matters we undertook to discuss ‐ especially solidarity ‐ appear when one starts by thinking about the primacy of skills and practices. Under this heading we consider (a) whether we need more case studies to make our points, and (b) whether national and other solidarities require willingness to die for the values that produce that solidarity. Second, we take up questions concerning the historical character of the skills of entrepreneurs, virtuous citizens, and culture figures. Here we shall (a) emphasize how we distinguish ourselves from earlier writers on these subjects, (b) consider essentialism, relational identities, and exclusion, (c) answer a number of Habermasian concerns raised by Hoy, (d) speak to Taylor's concern regarding the contingency of solidarity and forgetting, and (e) take up Grant's objection that we are both formalists and relativists. Third, we shall take up the concern, raised mostly by Borgmann, that historical disclosing, that is to say history as the West has known it, is over, and that now all that can be done by those who transform the practices is to make them more and more technological. 相似文献

AbstractSensory substitution refers to the phenomenon where object and environment information normally acquired through one sense can be obtained by another sense. For example, visual input being provided by hearing or touching. Sensory substitution devices are technological designs that transform the characteristics of one sensory modality into stimuli of another sensory modality. These devices were developed with two purposes: (1) to assist people with sensory disabilities in daily tasks; and (2) to study the involved mechanisms of brain plasticity. This article reviews studies in which sensory substitution phenomenon is employed as a methodological strategy to study visual perception. Furthermore, its use is discussed as an experimental platform to contrast new perceptual theories and underlying neurophysiological mechanisms that are currently under review. 相似文献
