ABSTRACT

Most academic literature is based on experiences of gang members in developed countries. This article explores the mechanisms of desistance among street gangs in El Salvador. Gangs in this Central American nation, which include MS-13 and the 18th Street gang, are known for complex structures and their transnational reach. Based on a survey with nearly 1,200 gang members and former gang members in El Salvador and 24 in-depth interviews with former gang members in rehabilitation programs, this study finds that the characteristics of the gang organization play a more significant role in the ways individuals exit the gangs in extremely violent contexts. It also shows that a religious experience is the most frequent mechanism to leave the group because it provides a safer alternative in those contexts.  相似文献

RESUMEN

El autor comienza explicando los factores que motivaron su interés por la psicolingüística evolutiva a principios de los sesenta. Tras exponer brevemente cuál es la significación del estudio del lenguje en la comprensión global del sujeto humano y justificar su atención a la adquisición de lenguas altamente inflexionales como el ruso o el turco, Slobin nos habla extensamente del Berkeley Crosslinguistic Acquisition Project (“Proyecto translingüístico sobre adquisición de Berkeley”), del cual fue uno de los máximos inspiradores. El autor aborda, además, cuestiones relativas a su teoría de la Gramática Básica Infantil, la síntesis de sus Principios Operativos para la adquisición del lenguaje o la posibilidad de aproximar las concepciones de Piaget y Chomsky. La última parte se reserva para las tendencias teóricas y de investigación que considera prometedoras en este campo, finalizando con algunas reflexiones en torno a la situación multilingüe de España y el estudio de la adquisición del lenguaje. Los comentarios de Miguel Pérez Pereira acerca de este importante investigador de la psicolingüística evolutiva introducen la entrevista.  相似文献

RESUMEN

El autor comienza señalando que la comprensión histórica del psicoanálisis exige un tratamiento plural, cuyo enfoque ilumine las diferentes perspectivas -así como su mutua interrelación- que han venido ilustrando su peculiar entidad. Por ello en este trabajo define de forma sistemática los principales enfoque históricos de los que es susceptible el fenómeno psicoanalítico: analítico-biográfico, socio-cultural, institucional-profesional y epistemológico, señalando los principales intereses temáticos y problemas que incluye cada uno y ofreciendo una selección de fuentes bibliográficas según tres criterios combinados: el mantenimiento de las obras clave clásicas, el carácter contemporáneo de las fuentes y el acceso a las mismas.  相似文献

RESUMEN

Todavía es reciente, en Psicología, el predominio de una actitud “epistemolófoba”, que rechazaba como acientífico cualquier intento de reflexión metacientífico sobre el objeto de la psicología y las formulaciones explicativas que define. En los últimos años, esta actitud ha cambiado y los psicólogos vuelven a considerar pertinente y necesaria la reflexión. En este trabajo se analizan los diversos modos de explicación de la conducta, sin exclusiones y a partir de la premisa de la “sobredeterminación” de la propia conducta. Se define la psicología científica como la ciencia de los principios, estructuras y funciones de la formalización conductual de la interrelación respectiva del hombre y su medio natural y social.  相似文献

Can individual differences in the tendency to use anxiety as a source of motivation explain emotional exhaustion? We examined the effects of using anxiety as a source of energy or as a source of information (viewed here as two forms of anxiety motivation) on emotional exhaustion. In Study 1, the use of anxiety as a source of energy predicted decreased emotional exhaustion one year later. Moreover, both forms of anxiety motivation buffered people from the detrimental effects of trait anxiety on later emotional exhaustion. In Study 2, an experiment, participants who were instructed to use anxiety as a source of energy reported lower emotional exhaustion following a stressful task, compared to those instructed to focus on the task or to simply do their best. These findings suggest that using anxiety as a source of motivation may protect people against emotional exhaustion.  相似文献

The fundamental problem proponents of truth conditional semantics must face is to specify what role a truth theory is supposed to play within a meaning theory. The most detailed proposal for tackling this problem is the account developed by Ernest Lepore and Kirk Ludwig. However, as I will show in this paper, theories along the lines of Lepore and Ludwig do not suffice to put someone into the position to understand the objectlanguage. The fundamental problem of truth conditional semantics thus remains unsolved.  相似文献

Four studies investigated the conditions under which minority group members respond to group‐based discrimination with increased identification with their group. We propose that minorities' interaction goals should serve as a moderator: seeking distance from the majority might keep minority identification alive in the face of perceived discrimination. These predictions were tested correlationally in Study 1 among Chinese immigrants in Australia (sample 1a) and children of rural migrant workers in a Chinese city (sample 1b). In Studies 2 and 3, perceived discrimination was manipulated among Romanian immigrants in France and Polish immigrants in Scotland. In Study 4, both minority goals and perceived discrimination were manipulated among a sample of international students in Australia. Results showed that only for those who were inclined to seek distance from the majority, minority group identification increased when discrimination was high compared with low. Discussion focuses on the way that seeking distance might be an important strategy for coping with discrimination. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

Stressful life events can result into declined memory performance at later age. One hypothesis suggests that stress affects the hippocampus, a brain area important for memory functioning. This study explored a potential relationship between the number of negative stressful life events and hippocampus-dependent declarative but not hippocampus-independent procedural memory performance in a community sample of 255 children, aged 6–12 years. The findings revealed that negative stressful life events were negatively related to verbal declarative memory, but not to nonverbal declarative and procedural memory. The memory impairments could not be accounted for by attention and sleep disturbances, and parenting characteristics as perceived by the child did not influence the vulnerability for the stress-related memory impairments. These findings provide further insight into the deleterious effects of negative stressful life events on learning in school-aged children.  相似文献

Current associative theories of contingency learning assume that inhibitory learning plays a part in the interference between outcomes. However, it is unclear whether this inhibitory learning results in the inhibition of the outcome representation or whether it simply counteracts previous excitatory learning so that the outcome representation is neither activated nor inhibited. Additionally, these models tend to conceptualize inhibition as a relatively transient and cue‐dependent state. However, research on retrieval‐induced forgetting suggests that the inhibition of representations is a real process that can be relatively independent of the retrieval cue used to access the inhibited information. Consistent with this alternative view, we found that interference between outcomes reduces the retrievability of the target outcome even when the outcome is associated with a novel (non‐inhibitory) cue. This result has important theoretical implications for associative models of interference and shows that the empirical facts and theories developed in studies of retrieval‐induced forgetting might be relevant in contingency learning and vice versa.  相似文献
