Dropping out of school is a break that permanently interrupts a pupil's schooling. Mainly psychological factors may contribute to this situation. The study focuses on the role played by some socio-emotional factors in the risk of dropping out of school in Lebanon. A quantitative research has been conducted on 504 teenagers attending middle school in 7th grade about their dropping out risks. Causal track analyses show that school learning experiences, social support provided by family and teachers, as well as some individual characteristics – (school anxiety, feelings of effectiveness related to school domain, expectations versus in school, school project) interact to increase or decrease the risk of dropping out. 相似文献

To find out which brain regions are responsible for the mental construction and recognition of a kanji character initiated by visually presented kanji radicals, rather than by information retained in the memory, a left hen radical and the corresponding right tsukuri radical were simultaneously presented randomly to either the left or right visual field of seven subjects. Thirty left hen radicals and the corresponding right tsukuri radicals were prepared as stimuli; this combination formed over 500 real or pseudo kanji characters. Instead of their usual left and right positions, the left hen radical was always presented above the right tsukuri radical. As quickly and correctly as possible, the subjects released a key when two kanji radicals constituted a single real kanji character and released another key otherwise. We recorded neuromagnetic responses as well as accuracy and reaction time. Left visual field superiority was observed as regards accuracy. This is in good agreement with previous neuropsychological results. Equivalent current dipoles were localized mainly in the left and/or right occipitotemporal regions (ventral visual pathways), the bilateral occipitoparietal regions (dorsal visual pathways) including the supramarginal region, and the areas surrounding the left superior temporal cortex. We suggest that these regions are related to reading and the mental construction of a kanji character from its radicals. 相似文献

Using a lexical decision task, the authors investigated whether brain asymmetries in the detection of emotionally negative semantic associations arise only at a perceptually discriminative stage at which lexical analysis is accurate or can already be found at crude and incomplete levels of perceptual representation at which word-nonword discrimination is based solely on guessing. Emotionally negative and neutral items were presented near perceptual threshold in the left and right visual hemifields. Word-nonword discrimination performance as well as the bias to classify a stimulus as a "word" (whether or not it actually is a word) were assessed for a normal, horizontal stimulus presentation format (Experiment 1) and for an unusual, vertical presentation format (Experiment 2). Results show that while the two hemispheres are equally able to detect affective semantic associations at a prelexical processing stage (both experiments), the right hemisphere is superior at a postlexical, perceptually discriminative stage (Experiment 2). Moreover, the findings suggest that only an unusual, nonoverlearned stimulus presentation format allows adequate assessment of the right hemisphere's lexical-semantic skills. 相似文献

Get‐out‐the‐vote mailers using explicit social pressure consistently increase electoral turnout; however, they often generate a negative reaction or backlash. One approach to increase turnout, yet alleviate backlash, may be to use implicit social pressure. An implicit social pressure technique that has shown promise is to display a set of eyes. Researchers contend eyes generate a feeling of being watched, which cues subjects to act in more prosocial ways to demonstrate compliance with social norms. Several studies support this argument, including two voter mobilization studies. The technique has not been widely tested, however, in the political context. In five randomized field experiments, we test the impact on turnout of mobilization mailers using eye displays. We extend previous research by testing for differences in effects between male and female eyes and across political cultures. The effects are substantively and statistically weak at best and inconsistent with previous findings. 相似文献

Induced motion is the illusory motion of a static stimulus in the opposite direction to a moving stimulus. Two types of induced motion have been distinguished: (a) when the moving stimulus is distant from the static stimulus and undergoes overall displacement, and (b) when the moving stimulus is pattern viewed within fixed boundaries that abut the static stimulus. Explanations of the 1st type of induced motion refer to mediating phenomena, such as vection, whereas the 2nd type is attributed to local processing by motion-sensitive neurons. The present research was directed to a display that elicited induced rotational motion with the characteristics of both types of induced motion: the moving stimulus lay within fixed boundaries, but the inducing and induced stimuli were distant from each other. The author investigated the properties that distinguished the two types of induced motion. In 3 experiments, induced motion persisted indefinitely, inter-ocular transfer of the aftereffect of induced motion was limited to about 20%, and the time-course of the aftereffect of induced motion could not be attributed to vection. Those results were consistent with fixed-boundary induced motion. However, they could not be explained by local processing. Instead, the results might reflect the detection of object motion within a complex flow-field that resulted from the observer's motion. 相似文献

Research investigating hemispheric asymmetries in meaning selection using homophonic homographs (e.g., bank), suggests that the left hemisphere (LH) quickly selects contextually relevant meanings, whereas the right hemisphere (RH) maintains a broader spectrum of meanings including those that are contextually irrelevant (e.g., Faust & Chiarello, 1998). The present study investigated cerebral asymmetries in maintaining the multiple meanings of two types of Hebrew homographs: homophonic homographs and heterophonic homographs (e.g., tear). Participants read homographs preceded by a biasing, or a non-biasing sentential context, and performed a lexical decision task on targets presented laterally, 1000 ms after the onset of the sentence-final ambiguous prime. Targets were related to either the dominant or the subordinate meaning of the preceding homograph, or unrelated to it. When targets were presented in the LVF/RH, dominant and subordinate meanings, of both types of homographs, were retained only when they were supported by context. In a non-biasing context, only dominant meanings of homophonic homographs were retained. Alternatively, when targets were presented in the RVF/LH, priming effects for homophonic homographs were only evident when meanings were supported by both context and frequency (i.e., when context favored the dominant meaning). In contrast, heterophonic homographs resulted in activation of dominant meanings, in all contexts, and activation of subordinate meanings, only in subordinate-biasing contexts. The results challenge the view that a broader spectrum of meanings is maintained in the right than in the left hemisphere and suggest that hemispheric differences in the time course of meaning selection (or decay) may be modulated by phonology. 相似文献

Several studies suggest a negative impact of ethnic diversity on cooperation, but most of them rely on attitudinal and other indirect measurements of cooperation or are derived from the artificial laboratory setting. We conducted a field experiment based on the lost‐letter technique across 52 neighborhoods in Berlin, Germany. The study has two aims. First, we investigate whether the negative effect of ethnic heterogeneity on cooperation holds for concrete cooperative behavior in a real‐world setting. Second, we test the most prominent psychological mechanism that has been proposed to explain the negative effects of heterogeneity on cooperation, namely in‐group favoritism. We do so by experimentally varying the ethnicity and religion of the senders of letters. We find strong support for the negative effect of ethnic diversity on cooperation. We find no evidence, however, of in‐group favoritism. Letters from Turkish or Muslim organizations were as often returned as those from German and Christian organizations, and the ethnic diversity effect was the same for all types of letters. 相似文献

Caplan has argued that the philosophy of medicine does not exist. Although I will not deny the points he makes, I will argue that the philosophy of medicine has characteristics of a developing field with the potential to meet all of Caplan's criteria. The argument is based on Dewey's established views on logical development for a field of inquiry, as well as pointing out how other criteria Caplan imposes can be fulfilled.The U.S. Government right to retain a non-exclusive, royalty free licence in and to any copyright is acknowledged. 相似文献

The aim of my paper is twofold. First, I show how the notion of phenomenal field can be used to examine, describe and understand
particular collective patterns pertaining to the everyday domain of our common social experience. Secondly, I outline the
role of the notion of “phenomenal field” in ethnomethodology. I briefly discuss Gurwitsch’s notion of functional meaning. After presenting the argument, I show “the locally achieved ordinariness of a common task”, that is the lining up of the
player of the two teams in the pitch, as an embodied coherence of figural contexture in its empirical perceptual details, as Garfinkel says.
