Attention Deficit Hyperactivity Disorder (ADHD) is one of the disorders causing the greatest impact, conditioning academic learning, quality of concentration, and capacity for self-regulation and control. The Diagnostic and Statistical Manual of Mental Disorders-IV (DSM-IV-TR) establishes the most commonly accepted criteria for diagnosis (Inattentive: ADHD-I, Hyperactive/impulsive: ADHD-HI, and Combined: ADHD-C), but currently, diverse studies disagree about whether to address it as a continuum with different degrees of intensity (subtype structure) or as specific disorders (counterposed profiles). Prior research has tested the hypothesis of differential categories with performance measures and cortical activation. The goal proposed herein is to confirm these results, incorporating a new measure, near-infrared hemoencefalography (nir-HEG), in order to control cortical activation through levels of blood oxygenation. For this purpose, we used a sample of 205 children between 8 and 13 years (105 control group, 28 with ADHD-I, 35 with ADHD-HI, and 37 with ADHD-C), administering a continuous performance test (TOVA), quantified electroencephalogram (Q-EEG), and nir-HEG. Results reflect the counterposed profiles hypothesis instead of the degrees of intensity, although the latter is more habitual and generalized.  相似文献

The influence of sublexical and lexico-syntactic factors during the grammatical gender assignment process in Spanish was studied in two experiments using the gender decision task. In Experiment 1, the regularity of the ending of gender-marked nouns (masculine nouns ended in $-o$ and feminine nouns ended in $-a$ ) and of nouns with gender-correlated but unmarked word-endings (e.g., $-ad$ ) was manipulated. The results showed that regularity affected reaction times and error rates only in the case of gender-marked nouns, suggesting that the mere statistical distribution of a word-ending across genders is not responsible for the regularity effect. In Experiment 2, gender-marked nouns and gender-unmarked nouns were preceded by a masked prime which could be a definite article (which provides information about the gender of the noun) or a possessive pronoun (which does not contain gender information). The presentation of the definite article led to shorter reaction times and less errors only when the word-ending was different from $-o$ or $-a$ . Taken together, these results indicate that gender assignment in Spanish is carried out through different processes depending on the noun ending: gender decisions for gender-marked nouns are based on the gender-to-ending distribution. Meanwhile, gender decisions for unmarked nouns seem to require the retrieval of the corresponding definite grammatical article, regardless of the statistical distribution of the noun ending across genders.  相似文献

The problem of epistemic bootstrapping requires explaining, in a principled manner, why a subject who engages in bootstrapping fails to know the conclusion of her reasoning. Existing proposed solutions to the problem provide unsatisfactory explanations regarding the bootstrapper's ignorance. This paper puts forward a novel solution and argues that it satisfactorily explains the ignorance of the bootstrapper, while avoiding the difficulties that other proposals face. Section 1 explains what epistemic bootstrapping is, defines the problem it poses for a theory of knowledge, and outlines the basic desiderata demanded of any acceptable solution to the problem. Section 2 explicates the proposal I defend throughout the rest of the paper. Here, I contend that the wrong−making feature of bootstrapping which ultimately explains the bootstrapper's ignorance is a failure to use an independent source in checking the accuracy of the reports of a given source. I call this explanation the “Independence proposal.” Section 2 also argues that the phenomenon of bootstrapping is broader than is usually assumed; there are cases of bootstrapping that do not fit the superficial structure of the prototypical cases discussed in the literature, and any good proposal should apply to these as well. Section 3 argues that the independence proposal does better than other current proposals in fulfilling the desiderata identified in Section 1. Section 4 sums up the central contributions of the paper.  相似文献

This essay is part of a collection of short essays solicited from authors around the globe who teach religion courses at the college level (not for professional religious training). They are published together with an introduction in Teaching Theology and Religion 18:3 (July 2015). The authors were asked to provide a brief overview of the curriculum, student learning goals, and pedagogical techniques employed in their courses.  相似文献

Error detection is one of the functions of the executive attention network, a brain system involved in executive control that includes the anterior cingulate cortex and other prefrontal regions. Despite the key role of this function in a wide range of life outcomes, very limited research has examined the early development of the network and whether its functional efficacy is related to environmental factors. Electrophysiological studies with adults have shown oscillatory activity in theta (4–7 Hz) range arising from medial frontal cortex that follows the detection of self‐committed or observed errors. In the current study, we designed a novel experimental procedure that involved a familiarization phase with simple three‐pieces puzzles followed by an experimental phase in which toddlers observed the puzzles being formed either correctly or incorrectly. Observation of incorrect configurations produced increased potentials in midline channels and greater power theta activity for both toddlers (= 56) and adults (= 14). In addition, socioeconomic status of the family in general, and parental education in particular, contributed to individual differences in the amplitude of the error‐related signal and associated theta power in toddlers, indicating that children raised in lower SES families show poorer activation of the executive attention network. These data demonstrate the influence of environmental factors at the earliest stages of development of the executive attention network. Importantly, the results show that error‐detection EEG signals can be used as neural markers of the initial development of executive attention, which can be of great help for the early detection of risk for developmental disorders involving deficits in this function.  相似文献
