Bigram Frequency,Number of Syllables and Morphemes and Their Effects on Lexical Decision and Word Naming

There has been an increasing volume of evidence supporting the role of the syllable in word processing tasks. Recently it has also been shown that orthographic redundancy, related to the pattern of bigram frequencies, could not explain the syllable number effect on lexical decision times. This was demonstrated on a large sample of words taken from the British Lexicon Project. In this study we extend this research by examining both lexical decision and word naming times taken from the English Lexicon Project . There was a syllable number effect for both tasks in the expected direction, and this effect was independent of the presence of a bigram trough. The research also examined the role of other bigram related variables and the number of morphemes on lexical decision and word naming times. The number of morphemes had a significant effect on both word processing tasks, with words with more morphemes producing faster reaction times and also fewer errors. This pattern was reversed for nonword lexical decision times. The results are discussed in the light of recent developments in models of reading.     

Generational patterns in Mexican Americans' academic performance in an unwelcoming political context

Research has shown that immigrant students often do better academically than their U.S.-born peers from the same ethnic group, but it is unclear whether this pattern holds for Mexican Americans. We examined the academic performance of four generations of Mexican American students from 5th to 10th grade looking for generation differences and explanations for them. Using data from 749 families, we tested a model with 5th-grade variables that differed by generation as potential mediators linking student generation to 10th-grade academic performance. Results showed that immigrants were academically behind at 5th grade but caught up by 7th. Only economic hardship mediated the long term relation between student generation and 10th-grade academic performance; maternal educational expectations and child language hassles, English usage, discrimination, and mainstream values helped explained the early academic deficit of immigrant children. The results identified potential targets for interventions to improve Mexican American students' academic performance.     

Christ Existing in Ordinary: Dietrich Bonhoeffer and Sanctification

One task of any doctrine of sanctification is to attend to a theological rationale for the significance of a habitual and developing Christian life within a broader salvific economy. This article introduces the problem of claiming ‘ordinary’ life as the arena and instrument of God and distils three elements of Bonhoeffer's early theology that might be employed to articulate a theology of sanctification as the counterpoint of justification: the realization of a new humanity in Christ that constitutes an ontology of justification; Christian devotion as the act of this new humanity in the Spirit; and the dynamic integrity accorded to historical existence.     

Disjunctivism unmotivated

Many naive realists are inclined to accept a negative disjunctivist strategy in order to deal with the challenge presented by the possibility of phenomenologically indistinguishable hallucination. In the first part of this paper I argue that this approach is methodologically inconsistent because it undercuts the phenomenological motivation that underlies the appeal of naive realism. In the second part of the paper I develop an alternative to the negative disjunctivist account along broadly Meinongian lines. In the last section of this paper I consider and evaluate a somewhat similar but rival view of hallucination developed by Mark Johnston.     

Human trace fear conditioning: right-lateralized cortical activity supports trace-interval processes

Pavlovian conditioning requires the convergence and simultaneous activation of neural circuitry that supports conditioned stimulus (CS) and unconditioned stimulus (US) processes. However, in trace conditioning, the CS and US are separated by a period of time called the trace interval, and thus do not overlap. Therefore, determining brain regions that support associative learning by maintaining a CS representation during the trace interval is an important issue for conditioning research. Prior functional magnetic resonance imaging (fMRI) research has identified brain regions that support trace-conditioning processes. However, relatively little is known about whether this activity is specific to the trace CS, the trace interval, or both periods of time. The present study was designed to disentangle the hemodynamic response produced by the trace CS from that associated with the trace interval, in order to identify learning-related activation during these distinct components of a trace-conditioning trial. Trace-conditioned activity was observed within dorsomedial prefrontal cortex (PFC), dorsolateral PFC, insula, inferior parietal lobule (IPL), and posterior cingulate (PCC). Each of these regions showed learning-related activity during the trace CS, while trace-interval activity was only observed within a subset of these areas (i.e., dorsomedial PFC, PCC, right dorsolateral PFC, right IPL, right superior/middle temporal gyrus, and bilateral insula). Trace-interval activity was greater in right than in left dorsolateral PFC, IPL, and superior/middle temporal gyrus. These findings indicate that components of the prefrontal, cingulate, insular, and parietal cortices support trace-interval processes, as well as suggesting that a right-lateralized fronto-parietal circuit may play a unique role in trace conditioning.     

The Power of Positive Recollections: Reducing Test Anxiety and Enhancing College Student Efficacy and Performance

This research sought to develop an intervention (targeting positive emotions and thoughts) as a mechanism for reducing test anxiety and raising confidence and performance in a sample of college students. Participants were randomly assigned to a positive thought task or a control task. Those in the positive‐thought condition, who were assigned to write about successful personal experiences, derived several benefits, when compared with control participants who wrote about their morning routines. Specifically, they experienced more positive affect and less negative affect, exhibited a more optimistic outlook, and reported less test anxiety. They were more likely to appraise the quiz confidently, perceiving it as a challenge rather than a threat. Perhaps most importantly, they exhibited superior performance on the quiz.     

Distributive Luck

Abstact

This article explores the Rawlsian goal of ensuring that distributions are not influenced by the morally arbitrary. It does so by bringing discussions of distributive justice into contact with the debate over moral luck initiated by Williams and Nagel. Rawls’ own justice as fairness appears to be incompatible with the arbitrariness commitment, as it creates some equalities arbitrarily. A major rival, Dworkin’s version of brute luck egalitarianism, aims to be continuous with ordinary ethics, and so is (a) sensitive to non-philosophical beliefs about free will and responsibility, and (b) allows inequalities to arise on the basis of option luck. But Dworkin does not present convincing reasons in support of continuity, and there are compelling moral reasons for justice to be sensitive to the best philosophical account of free will and responsibility, as is proposed by the revised brute luck egalitarianism of Arneson and Cohen. While Dworkinian brute luck egalitarianism admits three sorts of morally arbitrary disadvantaging which correspond to three forms of moral luck (constitutive, circumstantial, and option luck), revised brute luck egalitarian-ism does not disadvantage on the basis of constitutive or circumstantial luck. But it is not as sensitive to responsibility as it needs to be to fully extinguish the influence of the morally arbitrary, for persons under it may exercise their responsibility equivalently yet end up with different outcomes on account of option luck. It is concluded that egalitarians should deny the existence of distributive luck, which is luck in the levels of advantage that individuals are due.
