CEREBRAL ASYMMETRY AND COGNITIVE DEVELOPMENT IN CHILDREN: 总被引:1,自引:0,他引:1

Abstract— Phonemic awareness, the ability to abstract and manipulate auditory symbols, is a distinguishing human characteristic Neurobiological specializations in the left hemisphere and cultural exposure to language interact to shape development of this ability Modern imaging techniques now permit investigation of the interaction of these forces In this initial cross-sectional study, we found evidence for a shift from neurobiological to cultural regulation In young children, aged5 to 9, anatomical asymmetry of the auditory association cortex predicted phonemic awareness In older children, the relationship disappeared, as all children became skilled readers The findings suggest that children with different patterns of cognitive strengths and weaknesses may have different spatiotemporal patterns of cortical development. 相似文献

There appear to be at least two kinds of compound physical substances: compound pieces of matter, which have their parts essentially, and living organisms, which do not. Examples of the former are carbon atoms, salt molecules, and pieces of gold; and examples of the latter are protozoa, trees, and cats. Given that there are compound entities of these two kinds, and given that they can be created or destroyed by assembly or disassembly, questions naturally arise about the nature of the causal relations which unite their parts. In answer to these questions, we first argue that the parts of a compound piece of matter are connected via a relation of dynamic equilibrium of attractive and repulsive forces. We then argue that the parts of an organic living thing are united in a different way: they are functionally connected in a broadly Aristotelian sense which is compatible with an ultimately non-teleological, naturalistic biology. 相似文献

The effect of stimulus uncertainty on the stereoscopic resolution of letters was examined for two classes of letters: (1) letters presented stereoscopically as random-element stereograms, and (2) letters presented as two-dimensional physical contours. The variables of stimulus discriminability (stereoscopic vs. physical contours) and stimulus uncertainty (number of alternative letter targets) were combined factorially. Stereoscopically presented letters were more difficult to resolve, but stimulus uncertainty had the same effect for both stereoscopic and physically defined letters. The additivity of these two variables suggests that the perception of stereoscopic forms is an automatic process not impaired by uncertainty about the form to be resolved. 相似文献

Schedule thinning is an essential step in treating problem behavior, yet little research has been conducted to determine the method associated with sustained treatment effects. A frequently used method for thinning reinforcement is contingency‐based progressive delay, which requires the individual to meet some criteria before the reinforcers are returned. The response requirement could be dependent on (a) contextually appropriate behavior (differential reinforcement of alternative behavior‐based thinning) or (b) absence of problem behavior (differential reinforcement of other behavior‐based thinning). A translational arrangement with college students was implemented to determine the effects of these 2 response requirements. Tolerance was observed regardless of thinning method and was indicated by low rates of responding to the analogue problem behavior; however, more contextually appropriate behavior occurred during differential reinforcement of alternative behavior‐based thinning. These results support the use of response requirements for behaviors that are expected of the individual when reinforcement is not immediately forthcoming. 相似文献

We used discrete‐trial training to teach 3 children with autism to tact shapes of countries using 3 levels of reinforcement delay for correct responding: 0 s (immediate delivery), 6 s, and 12 s. Two of the 3 participants acquired the targets more quickly in the immediate‐delivery condition, suggesting that delays as brief as 6 s may be detrimental to learning tacts for some children. 相似文献

Transitions with nonhuman animals are typically framed as inescapable changes in signaled reinforcement schedules that result in a pause in responding unique to switches from rich to lean schedules. Pausing is considered to be a function of the aversive qualities of the contrasting reinforcement schedules. Transitions are typically framed in applied research as physical changes in location that evoke problem behavior maintained by the escape of an aversive event or resumption of a preferred event. We attempted to extend the basic framing of transitions to behaviors and contexts of social significance and evaluate a novel treatment for the problem of dawdling by 3 boys who had been diagnosed with autism spectrum disorder during rich‐to‐lean transitions. Dawdling during physical transitions was most readily observed when transitioning to lean contexts in Experiment 1. We then shortened transition duration in Experiment 2 by programming unsignaled and probabilistic rich reinforcement in the upcoming context. 相似文献

Fearful facial expressions are important social indicators of environmental threat. Among the various features of a fearful face, the eyes appear to be particularly important for recognizing and responding to these social cues. One way in which fearful faces facilitate observers’ behavior is by automatically capturing attention. This is true for both consciously and nonconsciously processed fearful faces. Recent research suggests that consciously processed fearful eyes alone are sufficient to capture observers’ attention. However, it is unknown as to whether or not nonconsciously processed, backward masked, fearful eyes are sufficient to facilitate spatial attention. To test this possibility, two dot-probe experiments with masked fearful eye stimuli were performed. In Experiment 1, we found that, relative to scrambled eyes, masked fearful eyes facilitate attentional orienting and delay attentional disengagement. In Experiment 2, we replicated this effect when comparing backward masked fearful to neutral eyes. Thus, the data suggest that nonconscious fearful eyes facilitate spatial attention through facilitated orienting and delayed disengagement. 相似文献

‘Ahab is a whaler’ and ‘Holmes is a whaler’ express different propositions, even though neither ‘Ahab’ nor ‘Holmes’ has a referent. This seems to constitute a theoretical puzzle for the Russellian view of propositions. In this paper, I develop a variant of the Russellian view, Plenitudinous Russellianism. I claim that ‘Ahab is a whaler’ and ‘Holmes is a whaler’ express distinct gappy propositions. I discuss key metaphysical and semantic differences between Plenitudinous Russellianism and Traditional Russellianism and respond to objections that stem from those differences. 相似文献

The 27‐item Monetary Choice Questionnaire (MCQ; Kirby, Petry, & Bickel, 1999) and 30‐item Probability Discounting Questionnaire (PDQ; Madden, Petry, & Johnson, 2009) are widely used, validated measures of preferences for immediate versus delayed rewards and guaranteed versus risky rewards, respectively. The MCQ measures delayed discounting by asking individuals to choose between rewards available immediately and larger rewards available after a delay. The PDQ measures probability discounting by asking individuals to choose between guaranteed rewards and a chance at winning larger rewards. Numerous studies have implicated these measures in addiction and other health behaviors. Unlike typical self‐report measures, the MCQ and PDQ generate inferred hyperbolic temporal and probability discounting functions by comparing choice preferences to arrays of functions to which the individual items are preconfigured. This article provides R and SPSS syntax for processing the MCQ and PDQ. Specifically, for the MCQ, the syntax generates k values, consistency of the inferred k, and immediate choice ratios; for the PDQ, the syntax generates h indices, consistency of the inferred h, and risky choice ratios. The syntax is intended to increase the accessibility of these measures, expedite the data processing, and reduce risk for error. 相似文献
