Computer speech-based remediation for reading disabilities: the size of spelling-to-sound unit in a transparent orthography

This study was designed to assess the effects of four reading-training procedures for children with reading disabilities (RD) in a transparent orthography, with the aim of examining the effects of different spelling-to-sound units in computer speech-based reading. We selected a sample of 83 Spanish children aged between 7 years 1 month and 10 years 6 months (M = 105.2, SD = 7.8) whose pseudoword reading performance was below the 25th percentile and IQ > 90. The participants were randomly assigned to five groups: (a) the whole-word training group (WW) (n = 17), (b) the syllable training group (S)(n = 16), (c) the onset-rime training group (OR) (n = 17), (d) the phoneme training group (P) (n = 15), and (e) the untrained control group (n = 18). Children were pre- and post-tested in word recognition, reading comprehension, phonological awareness, and orthographic and phonological tasks. The results indicate that experimental groups who participated in the phoneme and syllable conditions improved their word recognition in comparison with the control group. In addition, dyslexics who participated in the phoneme, syllable, and onset-rime conditions made a greater number of requests during computer-based word reading under conditions that required extensive phonological computation (low frequency words and long words). Reading time, however, was greater for long words in the phoneme group during computer-based reading. These results suggest the importance of training phonological processes in improving word decoding in children with dyslexia who learn in a consistent orthography.     

On pedagogy

Humans are adapted to spontaneously transfer relevant cultural knowledge to conspecifics and to fast-learn the contents of such teaching through a human-specific social learning system called 'pedagogy' (Csibra & Gergely, 2006). Pedagogical knowledge transfer is triggered by specific communicative cues (such as eye-contact, contingent reactivity, the prosodic pattern of 'motherese', and being addressed by one's own name). Infants show special sensitivity to such 'ostensive' cues that signal the teacher's communicative intention to manifest new and relevant knowledge about a referent object. Pedagogy offers a novel functional perspective to interpret a variety of early emerging triadic communicative interactions between adults and infants about novel objects they are jointly attending to. The currently dominant interpretation of such triadic communications (mindreading) holds that infants interpret others' object-directed manifestations in terms of subjective mental states (such as emotions, dispositions, or intentions) that they attribute to the other person's mind. We contrast the pedagogical versus the mindreading account in a new study testing 14-month-olds' interpretation of others' object-directed emotion expressions observed in a communicative cueing context. We end by discussing the far-reaching implications of the pedagogical perspective for a wide range of early social-cognitive competences, and for providing new directions for future research on child development.     

Thinking Without Words: An Overview for Animal Ethics

In Thinking without Words I develop a philosophical framework for treating some animals and human infants as genuine thinkers. This paper outlines the aspects of this account that are most relevant to those working in animal ethics. There is a range of different levels of cognitive sophistication in different animal species, in addition to limits to the types of thought available to non-linguistic creatures, and it may be important for animal ethicists to take this into account in exploring issues of moral significance and the obligations that we might or might not have to non-human animals. I am grateful for comments on an earlier version from Robert Francescotti and Clare Palmer.     

轻度认知损伤的语义记忆研究述评

轻度认知损伤（Mild cognitive impairment,MCI）是介于正常老化与痴呆之间的过渡阶段,表现为与年龄和教育程度不相称的认知功能减退。本文回顾了近期有关MCI语义记忆的研究,分析比较了各研究的实验任务及结果,得出MCI患者存在一定程度的由多种原因造成的语义记忆损伤,语义记忆测验对MCI的早期筛查和转归预测有重要作用。最后指出将来的研究需要将包括语义记忆成分在内的多种认知测验相结合,以便及早发现有可能发展为痴呆的危险个体并开展相应干预。     

Two Dimensions of the Ethical Problems Related to Nanotechnology

The current literature on nanoethics focuses on a wide array of topics such as equity, privacy, military, environment, human enhancement, intellectual property, and security. The identification of those topics leads to the adoption of an ethical stance, which we call the in itself dimension. In this article we argue that even though it is correct to identify the areas where ethical problems are imperative to deal with (in itself dimension), it is a partial approach. This is because the in itself dimension pays no attention to another ethical stance; one that does not have anything to do with individual or collective responsibilities, but rather with the socio-economic system into which those responsibilities are embedded. We call this second issue the contextual dimension.     

The attentional blink: A review of data and theory

Under conditions of rapid serial visual presentation, subjects display a reduced ability to report the second of two targets(Target2; T2) in a stream of distractors if it appearswithin200-500 msec of Target 1 (Tl). This effect. known as the attentional blink(AB),has been central in characterizing the limits of humans’ ability to consciously perceive stimuli distributed across time. Here, we review theoretical accounts of the AB and examine how they explain key findings in the literature. We conclude that the AB arises from attentional demands of Tl for selection, working memory encoding, episodic registration,and response selection, which prevents this high-level central resource from being applied to T2 at shortT1-T2 lags. Tl processing also transiently impairs the redeployment of these attentional resources to subsequent targets and the inhibition of distractors that appear in close temporal proximity to T2. Although these findings are consistent with a multifactorial account of the AB,they can also be largely explained by assuming that the activation of these multiple processes depends on a common capacity-limited attentional process for selecting behaviorally relevant events presented among temporally distributed distractors. Thus, at its core, the attentional blink may ultimately reveal the temporal limits of the deployment of selective attention.     

The Relationships Between Mexican American Acculturation,Cultural Values,Gender, and Help‐Seeking Intentions

This study examined the relationships between Mexican acculturation, cultural values, gender, and help‐seeking intentions among Mexican American community college students. Findings suggest that as Mexican Americans lose their culture of origin and increase their generational status, their attitudes toward help seeking become less favorable. This contradicts cultural barrier theory as an explanation for underuse of mental health services by Mexican Americans. Furthermore, adherence to traditional Mexican culture and cultural values may actually encourage help seeking.     

The Reverse-Caricature Effect Revisited: Familiarization With Frontal Facial Caricatures Improves Veridical Face Recognition

Prior research suggests that recognition of a person's face can be facilitated by exaggerating the distinctive features of the face during training. We tested if this 'reverse-caricature effect' would be robust to procedural variations that created more difficult learning environments. Specifically, we examined whether the effect would emerge with frontal rather than three-quarter views, after very brief exposure to caricatures during the learning phase and after modest rotations of faces during the recognition phase. Results indicate that, even under these difficult training conditions, people are more accurate at recognizing unaltered faces if they are first familiarized with caricatures of the faces, rather than with the unaltered faces. These findings support the development of new training methods to improve face recognition.

Purpose  

The authors examine the influence of employees’ social regard toward the customers on customer satisfaction, trust, and word of mouth. In addition, we analyzed the moderating role of length of relationship between the service provider and the customer on the effects of social regard on the customer relationship outcomes.
