The purpose was to examine the effects of an exercise pilot intervention informed by Self-determination theory. The 64 participants were randomized into experimental and control group. The main questions were whether the intervention would influence (a) exercise level, (b) motivation quality, and (c) autonomy and competence need satisfaction. We also examined the indirect effects of self-determined motivation on exercise. Significant intervention effects were found regarding exercise level and motivation quality. Also, intervention effect on exercise was found to be mediated by motivation quality and identified regulation. The results provide interesting information about the underlying mechanisms involved in exercise behaviour change. 相似文献

This article analyzes the traces and configuration of three syntagmatic interpretation models in the educational text produced by Israel’s state religious educational system: the modus, the hermetic and the gnostic models, which together add up to a fourth, and unique one: the messianic nationalist model of interpretation. This interpretive model has a concrete configuration which, as opposed to similar but secular educational models, uses transcendental motifs in order to pragmatically organize the explanation of ‘reality’. From this point of view the messianic nationalist model presents a case study in religious education, which integrates between modern (i.e., nationalist) and traditional (religious) motifs in a relatively flexible way, situating itself between a fundamentalist religious idiosyncrasy and a secular one. Theoretically and methodologically the article develops the textual analysis of educational texts. The specific analysis presented here assumes that an educational ideological text interprets, and is interpreted constantly by, its producers and its users as well. 相似文献

This study investigated agent and expression intensity recognition in point-light displays depicting dancing performances.
In a first session, participants danced with two different expression intensities to music, solo or in dyads. In a subsequent
session, they watched point-light displays of 1–5-s duration, depicting their own, their partner’s or another participant’s
recorded actions, and were asked to identify the agent (self vs. partner vs. stranger) and the intended expression intensity
(expressive vs. inexpressive) of the performer. The results indicate that performer identity and expression intensity could
be discerned reliably from displays as short as 1 s. The accuracy in judgment increased with exposure duration and, for performer
identification, with higher expression intensity. Judgment accuracy in agent and expression intensity recognition tasks correlated
with self-report empathy indices. Accuracy correlated also with confidence in judgment, but only in the intensity recognition
task. The results are discussed in relation to perceptual and neural mechanisms underlying action and intention recognition. 相似文献

The present research examined the interplay of individual differences in self‐regulatory mechanisms as outlined in regulatory focus theory (promotion‐ and prevention‐focus) and a cue of being watched in the context of cooperative behaviour. Study 1 revealed that the more individuals' habitual self‐regulatory orientation is dominated by a vigilant prevention focus, the more likely they are to act cooperatively (i.e. to donate money to natural conservation organizations) when a subtle cue of being watched renders reputational concerns salient. In contrast, when no such cue is provided individuals' habitual vigilant self‐regulatory orientation is negatively related to cooperative behaviour. Study 2 replicated the results of the initial study and examined interpersonal sensitivity (empathic concern) as a potential mediator of the observed effects.

The psycholinguistic literature has identified two syntactic adaptation effects in language production: rapidly decaying short-term priming and long-lasting adaptation. To explain both effects, we present an ACT-R model of syntactic priming based on a wide-coverage, lexicalized syntactic theory that explains priming as facilitation of lexical access. In this model, two well-established ACT-R mechanisms, base-level learning and spreading activation, account for long-term adaptation and short-term priming, respectively. Our model simulates incremental language production and in a series of modeling studies, we show that it accounts for (a) the inverse frequency interaction; (b) the absence of a decay in long-term priming; and (c) the cumulativity of long-term adaptation. The model also explains the lexical boost effect and the fact that it only applies to short-term priming. We also present corpus data that verify a prediction of the model, that is, that the lexical boost affects all lexical material, rather than just heads. 相似文献

It has long been known that memory is not a single process. Rather, there are different kinds of memory that are supported by distinct neural systems. This idea stemmed from early findings of dissociable patterns of memory impairments in patients with selective damage to different brain regions. These studies highlighted the role of the basal ganglia in non-declarative memory, such as procedural or habit learning, contrasting it with the known role of the medial temporal lobes in declarative memory. In recent years, major advances across multiple areas of neuroscience have revealed an important role for the basal ganglia in motivation and decision making. These findings have led to new discoveries about the role of the basal ganglia in learning and highlighted the essential role of dopamine in specific forms of learning. Here we review these recent advances with an emphasis on novel discoveries from studies of learning in patients with Parkinson's disease. We discuss how these findings promote the development of current theories away from accounts that emphasize the verbalizability of the contents of memory and towards a focus on the specific computations carried out by distinct brain regions. Finally, we discuss new challenges that arise in the face of accumulating evidence for dynamic and interconnected memory systems that jointly contribute to learning. 相似文献

In this essay we develop and argue for the adoption of a more comprehensive model of research ethics than is included within
current conceptions of responsible conduct of research (RCR). We argue that our model, which we label the ethical dimensions
of scientific research (EDSR), is a more comprehensive approach to encouraging ethically responsible scientific research compared
to the currently typically adopted approach in RCR training. This essay focuses on developing a pedagogical approach that
enables scientists to better understand and appreciate one important component of this model, what we call intrinsic ethics. Intrinsic ethical issues arise when values and ethical assumptions are embedded within scientific findings and analytical
methods. Through a close examination of a case study and its application in teaching, namely, evaluation of climate change
integrated assessment models, this paper develops a method and case for including intrinsic ethics within research ethics
training to provide scientists with a comprehensive understanding and appreciation of the critical role of values and ethical
choices in the production of research outcomes. 相似文献

Previous research shows that sensory and motor systems interact during perception, but how these connections among systems are created during development is unknown. The current work exposes young children to novel 'verbs' and objects through either (a) actively exploring the objects or (b) by seeing an experimenter interact with the objects. Results demonstrate that the motor system is recruited during auditory perception only after learning involved self-generated interactions with objects. Action observation itself led to above-baseline activation in one motor region during visual perception, but was still significantly less active than after self-generated action. Therefore, in the developing brain, associations are built upon real-world interactions of body and environment, leading to sensori-motor representations of both objects and words. 相似文献

A highly familiar type of movement occurs whenever a person walks towards you. In the present study, we investigated whether this type of motion has an effect on face processing. We took a range of different 3D head models and placed them on a single, identical 3D body model. The resulting figures were animated to approach the observer. In a first series of experiments, we used a sequential matching task to investigate how the motion of an approaching person affects immediate responses to faces. We compared observers’ responses following approach sequences to their performance with figures walking backwards (receding motion) or remaining still. Observers were significantly faster in responding to a target face that followed an approach sequence, compared to both receding and static primes. In a second series of experiments, we investigated long-term effects of motion using a delayed visual search paradigm. After studying moving or static avatars, observers searched for target faces in static arrays of varying set sizes. Again, observers were faster at responding to faces that had been learned in the context of an approach sequence. Together these results suggest that the context of a moving body influences face processing, and support the hypothesis that our visual system has mechanisms that aid the encoding of behaviourally-relevant and familiar dynamic events. 相似文献
