Abstract Recent discussions of “reality” will be argued as having failed to differentiate clearly between two levels: the level of things, people and events that can, for most purposes, reasonably be taken as existing “out there”; and the level of the meanings that can be applied to them by an observer. An anarchistic approach will be recommended. 相似文献

RESUMENBronckart comienza revisando su trayectoria científica y explicando cuáles son sus dos enfoques básicos: el análisis del contexto o de situaciones y el análisis del lenguaje en función de sus operaciones subyacentes definidas en el marco de las teorías de la enunciación. Seguidamente justifica su renuncia a posiciones estructuralistas porque no tienen en cuenta el problema de las relaciones funcionales ni prestan atención al contexto. El autor relaciona las operaciones psicológicas con universales funcionales diferenciándolos de los estructurales de Chomsky y del enfoque de Searle, defendiendo su interés por la lingüística comparativa. Seguidamente aborda el tema de análisis de textos en ambientes escolares, sugiriendo que hay que sensibilizar a los educadores sobre el hecho de que constantemente estamos en situaciones de comunicación que van cambiando y crear instrumentos para que puedan analizar su propia práctica. Con relación al aspecto cognitivo del lenguaje, enfatiza la proliferación excesiva de los enfoques representativos y seguidamente desarrolla qué entiende por especificidad de la naturaleza del lenguaje y de su carácter comunicativo. Esta entrevista aborda, además, cuestiones tales como el fenómeno presuposicional, las aportaciones de Vygotsky o las experiencias de enseñar lenguaje a chimpancés, y finaliza planteando algunos aspectos de la teoría de Culioli. 相似文献

The U.S. Reserve Officer Training Program (ROTC) conducts systematic assessments of cadets’ leadership abilities during field training exercises (FTX) to assess their leadership abilities. While cadets in ROTC programs learn specific tactical operation procedures to augment FTX performances, much less is known about the relationship between psychological variables and squad leadership performance. To this end, 220 cadets completed self-efficacy, psychological flexibility, and grit questionnaires, which were then compared to FTX performance scores. Results underscored that only self-efficacy was significantly related to cadets’ squad leadership ability. Furthermore, prior service in the U.S. Army had no effect on the performance score one attained, highlighting an interesting paradox. Therefore, while self-efficacy can be cultivated through prior experiences, it seems more prudent to educate ROTC cadets on how to apply psychological skills to bolster self-efficacy in preparation for upcoming challenging leadership experiences. 相似文献

In the social sciences, mediation analysis has typically been formulated in the context of linear models using the Baron &; Kenny (1986) approach. Extensions to nonlinear models have been considered but lack formal justification. By placing mediation analysis within the counterfactual framework of causal inference one can define causal mediation effects in a way that is not tied to a specific statistical model and identify them under certain no unmeasured confounding assumptions. Corresponding estimation procedures using parametric or nonparametric models, based on the so-called mediation formula, have recently been proposed in the psychological literature and made accessible through the R-package mediation. A number of limitations of the latter approach are discussed and a more flexible approach using natural effects models is proposed as an alternative. The latter builds on the same counterfactual framework but enables interpretable and parsimonious modeling of direct and mediated effects and facilitates tests of hypotheses that would otherwise be difficult or impossible to test. We illustrate the approach in a study of individuals who ended a romantic relationship and explore whether the effect of attachment anxiety during the relationship on unwanted pursuit behavior after the breakup is mediated by negative affect during the breakup. 相似文献

The RULER Approach to Social and Emotional Learning (“RULER”) is designed to improve the quality of classroom interactions through professional development and classroom curricula that infuse emotional literacy instruction into teaching–learning interactions. Its theory of change specifies that RULER first shifts the emotional qualities of classrooms, which are then followed, over time, by improvements in classroom organization and instructional support. A 2-year, cluster randomized controlled trial was conducted to test hypotheses derived from this theory. Sixty-two urban schools either integrated RULER into fifth- and sixth-grade English language arts (ELA) classrooms or served as comparison schools, using their standard ELA curriculum only. Results from multilevel modeling with baseline adjustments and structural equation modeling support RULER’s theory of change. Compared to classrooms in comparison schools, classrooms in RULER schools exhibited greater emotional support, better classroom organization, and more instructional support at the end of the second year of program delivery. Improvements in classroom organization and instructional support at the end of Year 2 were partially explained by RULER’s impacts on classroom emotional support at the end of Year 1. These findings highlight the important contribution of emotional literacy training and development in creating engaging, empowering, and productive learning environments. 相似文献

We examine the association between neighborhood socio-economic disadvantage and perceived stress during middle and late adolescence among African American youth (N = 665; 51 % female; M = 15.9 years at baseline). In addition, we explored the ways through which neighborhood stressors interacted with an individual’s intra- and interpersonal resources (e.g., coping, social support and substance use), to affect their perceived stress trajectories during adolescence. First, we tested a neighborhood stressors model and found that youth who lived in neighborhoods with greater socioeconomic disadvantage had higher baseline stress and a steeper increase in stress over time. When we included individual-level risk and promotive factors in the model, however, the effect of neighborhood disadvantage on perceived stress was no longer significant, and the stress trajectory was explained by adolescent substance use, social support and perceptions of the neighborhood. Our results support theories of stress and coping, and the importance of proximal intra- and interpersonal factors in either amplifying or mitigating perceptions of stress. We discuss implications of the neighborhood context and how our findings may inform future prevention and intervention related to adolescent stress and development. 相似文献

In two experiments, 18-month-old infants’ categorization of 3D replicas and 2D photographs of the same animals and vehicles were compared to explore infants’ flexibility in categorization across different object representations. Using a sequential touching procedure, infants completed one superordinate and two basic-level categorization tasks with 3D replicas, 2D cut out photographs, or 2D images on photo cubes (“2D cubes”). For superordinate sets, 3D replicas elicited longer mean run lengths than 2D cut outs, and 3D replicas elicited equivalent mean run lengths as 2D cubes. For basic-level sets, infants categorized high-contrast animal sets when presented with 3D replicas, but they failed to categorize any of the 2D photograph sets. Categorization processes appear to differ for 3D and 2D stimuli, and infants’ discovery of object properties over time while manipulating objects may facilitate categorization, as least at the superordinate level. These findings are discussed in the context of infants’ representation abilities and the integration of perception and action. 相似文献

Most health decision-making models posit that cost-benefit analyses underlie decisions to make changes in health-related behavioral practices. In a series of studies, participants imagined either increasing or decreasing the frequency of a variety of health behaviors and estimated the consequences of those changes. In Studies 1 and 2, individuals consistently estimated that increasing a health behavior produced greater consequences than did decreasing the behavior by an equivalent amount. The results of Study 3 demonstrated that this effect is due to differences in how individuals judge the impact of health behavior changes which involve not engaging in the behavior at all versus other types of changes. Taken together, these findings suggest that perceptions of the outcomes afforded by health behavior changes depend on both the behavioral frequency and direction of changes in behavior an individual is considering. This asymmetry has the potential to help explain patterns of behavior in a range of important health domains and may impact the effectiveness of behavior change interventions. 相似文献
