Development and validation of a questionnaire about the main variables affecting the individual investor's behavior in the Stock Exchange. There is a considerable lack of information about the methodology usually used in most of the studies about individual investor's behavior. The studies reviewed do not show the method used in the selection of the items or the psychometric properties of the questionnaires. Because of the importance of investment in the Stock Exchange nowadays, it seems relevant to obtain a reliable instrument to understand individual investor's behavior in the Stock Exchange. Therefore, the goal of the present work is to validate a questionnaire about the main variables involved in individual investors' behavior in the Stock Exchange. Based on previous studies, we elaborated a questionnaire using the Delphi methodology with a group of experts. The internal consistency (Cronbach alpha=.934) and validity evidence of the questionnaire show that it may be an effective instrument and can be applied with some assurance. 相似文献

This work presents an analysis of the role of animacy in attachment preferences of relative clauses to complex noun phrases in European Portuguese (EP). The study of how the human parser solves this kind of syntactic ambiguities has been focus of extensive research. However, what is known about EP is both limited and puzzling. Additionally, as recent studies have stressed the importance of extra-syntactic variables in this process, two experiments were carried out to assess EP attachment preferences considering four animacy conditions: Study 1 used a sentence-completion-task, and Study 2 a self-paced reading task. Both studies indicate a significant preference for high attachment in EP. Furthermore, they showed that this preference was modulated by the animacy of the host NP: if the first host was inanimate and the second one was animate, the parser's preference changed to low attachment preference. These findings shed light on previous results regarding EP and strengthen the idea that, even in early stages of processing, the parser seems to be sensitive to extra-syntactic information. 相似文献

Common coding theory states that perception and action may reciprocally induce each other. Consequently, motor expertise should
map onto perceptual consistency in specific tasks such as predicting the exact timing of a musical entry. To test this hypothesis,
ten string musicians (motor experts), ten non-string musicians (visual experts), and ten non-musicians were asked to watch
progressively occluded video recordings of a first violinist indicating entries to fellow members of a string quartet. Participants
synchronised with the perceived timing of the musical entries. Results revealed significant effects of motor expertise on
perception. Compared to visual experts and non-musicians, string players not only responded more accurately, but also with
less timing variability. These findings provide evidence that motor experts’ consistency in movement execution—a key characteristic
of expert motor performance—is mirrored in lower variability in perceptual judgements, indicating close links between action
competence and perception. 相似文献

The Division of Household Labor in Spanish Dual Earner Couples: Testing Three Theories 总被引:1,自引:0,他引:1
Although the participation of men in household activities has increased, this has not prompted an equitable division of household activities among men and women, since Spanish women continue to perform a greater share of these activities than Spanish men. This article explores the explanatory potential of three theoretical approaches (traditional gender division, role-strain and the resource-bargaining approach) to account for the emergence of different patterns in the division of unpaid work among Spanish dual earner couples. Using a representative sample of 2,877 Spanish workers and through logit ordered models, our study reveals that the three models contribute to the explanation of the different patterns of household labor and, therefore, may be regarded as complementary. 相似文献

The present study investigated whether offset cues have the same attentional consequences in the spatial Stroop effect as
onset cues. Experiments 1 and 2 compared the attentional effects of onset–offset cues versus offset cues on the spatial Stroop
effect, whereas Experiment 3 compared the attentional effects of onset versus offset cues. Across these experiments, independent
of cue type (onset–offset or onset vs. offset) and even at long stimulus-onset asynchrony, attentional cueing did not revert
into inhibition of return and was modulated by spatial Stroop with greater cueing effects for incongruent arrow’s direction
and position. In addition, onset–offset or onset and offset cues produced comparable cueing effects in the location-direction
congruent condition, and onset–offset or onset cues produced greater facilitation than offset cues in the incongruent condition.
From a different perspective, peripheral cueing modulated the spatial Stroop effect in the same direction for onset–offset
or onset and offset cues, although the reduction in spatial Stroop at cued locations was smaller with offset than with onset–offset
or onset cues. 相似文献

Using an international dataset of about 35 000 subjects, this paper provides an empirical example of high‐stakes incentives in relation to religious practice. First, we show that incentives (based on absolute belief) play a salient role in religious performance. Second, we find that when both positive (heaven) and negative (hell) incentives are available the former are more effective than the latter. Specifically, it is shown that beliefs in heaven are much more relevant than beliefs in hell when estimating the production of religious commodities (church‐attendance and praying equations).

In this paper, we describe a digital scenario where we simulated the emergence of self-organized symbol-based communication among artificial creatures inhabiting a virtual world of unpredictable predatory events. In our experiment, creatures are autonomous agents that learn symbolic relations in an unsupervised manner, with no explicit feedback, and are able to engage in dynamical and autonomous communicative interactions with other creatures, even simultaneously. In order to synthesize a behavioral ecology and infer the minimum organizational constraints for the design of our creatures, we examined the well-studied case of communication in vervet monkeys. Our results show that the creatures, assuming the role of sign users and learners, behave collectively as a complex adaptive system, where self-organized communicative interactions play a major role in the emergence of symbol-based communication. We also strive in this paper for a careful use of the theoretical concepts involved, including the concepts of symbol and emergence, and we make use of a multi-level model for explaining the emergence of symbols in semiotic systems as a basis for the interpretation of inter-level relationships in the semiotic processes we are studying. 相似文献

The study of touch has recently grown, due mainly to the extensive use of several types of actuators that stimulate several
subsystems of touch. There is a widespread interest in applying these mechanisms to the study of the neurophysiological correlates
of tactual perception. In this article, we present a new device (the tactile spinning wheel [TSW]) for delivering textured
surfaces to the finger pad. The TSW allows one to control several parameters of the stimulation (angular speed, texture, etc.)
and, connected to an EEG recording system, makes it possible to study neural electrophysiological events. The device consists
of a rotating platform on which the tactile stimuli are fixed, a system that synchronizes stimuli onset with the EEG system,
and an electronic interface that controls the platform. We present the technical details of the TSW, its calibration, and
some experimental results we have obtained with this device. 相似文献

In a recent paper called To think human out of the machine paradigm, it is stated that psychological science operates within a machine paradigm that is committed to mechanical causality. In
addition, it is emphasizes the epistemological and methodological limitations of explanations based in deterministic mechanics
and instead argues for the need of an ‘organic paradigm’ that takes into consideration psychological processes such as subjectivity,
inter-subjectivity, and agency. Although there is no doubt that much psychological science has operated under a machine paradigm,
we argue that recent psychological research is pursued using a wide variety of approaches and with an absence of a partially
integrated meta-theoretical corpus. The present situation looks more like a Tower of Babel of epistemological approaches and
empirical programs. The reconsideration of the organic paradigm and an explicitly addressed epistemological framework could
constitute a step forward and lead to an explanatory pluralism built on greater dialogue within the psychological sciences. 相似文献
