Using mnemonic images and explicit sound contrasting to help Japanese children learn English alphabet sounds

Although mnemonics have been shown to be effective in remembering letter-sound associations, the use of foreign words as cues for English phonemes had not been investigated. Learning phonemes in Japan is challenging because the Japanese language is based on a different sound unit called mora (mostly consonant-vowel combinations). This study investigated the effectiveness of using mnemonic images utilizing Japanese words as cues for the phonemes, and explicit sound contrasting of phonemic sounds with morae they could be confused with, in facilitating children's acquisition of knowledge about alphabet letter-sound correspondence. The participants were 140 6th-grade Japanese students who were taught phoneme-consonant correspondence, with or without the use of mnemonics or explicit sound contrasting. Analysis of the students’ pre- and post-instruction assessments revealed significant interaction effects between types of instruction provided and instruction phase, indicating better performance in letter-sound association as a consequence of the inclusion of both mnemonics and explicit sound contrasting.     

Maintenance strategy selection with risky evaluations using RAHP

In recent years, maintenance, especially its preventive type, has been seen as an effective and considerable factor in improving the functions of machines. Maintenance plays a vital role in organizations by keeping and increasing the reliability, accessibility, the quality of products, risk mitigation, return improvement, and safety. An effective maintenance programme can be realized by implementing a proper maintenance strategy. Therefore, maintenance and its strategies have a special status in industries. However, selecting a proper maintenance strategy has always been a complex process because maintenance is a nonrepetitive task. Likewise, the lack of failure records and constant changes in the conditions of machines makes it further complicated. Hence, the decision‐making also depends on experts' opinions and because some kind of risk and uncertainty are always there in experts evaluations, the reliability of evaluations is questionable. The present study was aimed to develop a risk‐based model grounded on the analytical hierarchical process, namely, RAHP, to meet this need of maintenance. A case study from a steel rolling company was considered to evaluate the effectiveness of this model.     

The Efficacy of Toddler-Parent Psychotherapy for Fostering Cognitive Development in Offspring of Depressed Mothers

The efficacy of Toddler-Parent Psychotherapy (TPP) as a preventive intervention for fostering cognitive development in the offspring of depressed mothers was evaluated. Mothers with major depressive disorder and their toddlers were randomly assigned to TPP (n = 43) or to a nonintervention group (n = 54) and compared to a control group (n = 61) of women with no current or past mental disorder. At baseline (age 20 months), the groups did not differ on the Bayley Mental Development Index. At post-intervention follow-up (age 3 years), a relative decline in IQ was found in the depressed nonintervention group, whereas the depressed intervention and the normal control groups continued to be equivalent, with higher WPPSI-R Full Scale and Verbal IQs. The worst outcome was found among nonintervention children whose mothers had subsequent depressive episodes. The results confirm the developmental risks faced by offspring of depressed mothers and support the efficacy of the preventive intervention in safeguarding successful cognitive development in at-risk youngsters.

Schizophrenia Epigenesis?

I begin by examining how genetics drivesschizophrenia research, and raise both familiar andrelatively novel criticisms of the evidence putativelysupporting the genetic basis of schizophrenia. Inparticular, I call attention to a set of concernsabout the effects of placentation on concordance ratesof schizophrenia in monozygotic twins, which furtherweakens the case for schizophrenia's so-called stronggenetic component. I then underscore two criticalpoints. First, I emphasize the importance of takingseriously considerations about the complexity of bothontogenesis and the development of hereditarydiseases. The recognition of developmentalconstraints and supports is crucial, for attention todevelopment exposes the naivete of too many models ofgene action in the aetiology of disease. Secondly, Iattend to those schizophreniologists who ignoremethodological criticisms and thus presume a geneticbasis for schizophrenia, and then seek the schizophrenic genotype lacking an adequatephenotype. In response I attempt to demonstrate thenecessity of a sustained effort at characterizing thephenotype of schizophrenia as an enabling conditionfor the whole enterprise of psychiatric genetics – andfor psychiatry itself. Without the organism-levelphenotype, research at the level of genes will remainunproductive – assuming of course that research at thegenetic level is appropriate at all.     

儿童早期"心理理论"发展研究中的几个基本问题

儿童"心理理论"的发展研究是当今发展心理学中最活跃的领域之一.近年来,该领域的研究重点已逐渐由一般的发展描述,转向关于"心理理论"的缘起与发展机制的研究.由此,有许多密切相关的关于早期"心理理论"发生发展及其评估的基本问题,横亘于研究者面前,迄今仍悬而未决,并引发诸多争议.如何解决这些问题并理顺它们之间的关系,将极大地影响着该领域今后的研究进展.     

The Ecological Self: Metaphor and Developmental Experience?

The term ecological self, used within the fields of deep ecology and ecopsychology, is considered here from the viewpoint of developmental research and theory, within the context of contemporary relational psychoanalysis. Both developmental theory and more specifically our concept of health are explored with the inclusion of relatedness to the nonhuman world and an emphasis on embodiment and interactive experience. Illustrations and examples are drawn from research, clinical work with adults and the literature of natural history.     

Infant recall memory and communication predicts later cognitive development

This longitudinal study investigates the relation between recall memory and communication in infancy and later cognitive development. Twenty-six typically developing Swedish children were tested during infancy for deferred imitation (memory), joint attention (JA), and requesting (nonverbal communication); they also were tested during childhood for language and cognitive competence. Results showed that infants with low performance on both deferred imitation at 9 months and joint attention at 14 months obtained a significantly lower score on a test of cognitive abilities at 4 years of age. This long-term prediction from preverbal infancy to childhood cognition is of interest both to developmental theory and to practice.     

The effect of cues on young children's abilities to discriminate among thoughts, feelings and behaviours

OBJECTIVE: To determine if cues help young children discriminate among thoughts, feelings and behaviours. PARTICIPANTS: Ninety-six children aged 4-7 years from three schools in Norwich, UK. DESIGN: Within each age band (4, 5, 6, 7), children were randomised to the cue or the no cue condition on a stratified basis ensuring that equal numbers of boys and girls from each school were in each of the eight cells (cue condition x age). Cues were glove puppets and post boxes. The effect of IQ was controlled. MEASURES: A discrimination task, in which children were asked to identify a thought, a feeling and a behaviour from each of six brief stories, and a brief IQ assessment were administered to children individually. RESULTS: There was a significant effect of age and cue condition on performance; older children and those who were presented with the cue performed better. There were no gender differences and no interaction between cue condition and age. CONCLUSION: Many young children discriminated among thoughts, feelings and behaviours suggesting that they may be able to engage in this aspect of cognitive behaviour therapy. Simple cues (puppets and posting boxes) improved children's performance and these may be useful therapeutic tools with young children.     

Developmental dyscalculia and basic numerical capacities: a study of 8-9-year-old students

Thirty-one 8- and 9-year-old children selected for dyscalculia, reading difficulties or both, were compared to controls on a range of basic number processing tasks. Children with dyscalculia only had impaired performance on the tasks despite high-average performance on tests of IQ, vocabulary and working memory tasks. Children with reading disability were mildly impaired only on tasks that involved articulation, while children with both disorders showed a pattern of numerical disability similar to that of the dyscalculic group, with no special features consequent on their reading or language deficits. We conclude that dyscalculia is the result of specific disabilities in basic numerical processing, rather than the consequence of deficits in other cognitive abilities.
