儿童早期统计学习的发展:听觉语言领域的优势

目前,研究关于儿童早期语言领域的统计学习能力是否随年龄发展尚未得到一致的结论,且缺乏在相同实验参数下对不同领域和感觉通道统计学习早期发展的系统考察。研究选择中班到二年级5~8岁的儿童,首次系统地考察了早期听觉和视觉通道中语言和非语言领域统计学习的发展。儿童首先在熟悉阶段听或看由无意义三联体构成的声音流或图片流;接着在测验阶段对三联体和非三联体做二择一判断。结果发现:1.儿童对听觉音节材料的统计学习能力从5~6岁快速发展,并在6岁时达到了和8岁儿童相当的水平,表明在儿童早期听觉语言领域的统计学习存在发展优势;2.从6岁起,儿童已能对视觉文字材料进行统计学习,且无论是视觉文字、物品图片还是听觉环境声音材料,其统计学习成绩均随年龄增长而提高。这些结果说明统计学习可能既遵循某种领域一般的原则,又受到输入刺激特性的限制,是一种多成分的能力。     

Development of rules and strategies: balancing the old and the new

The experiments described in the lead articles replicate findings from previous studies of development of knowledge about balance scales, add several new findings, and raise four key questions: (a) How can rule use best be assessed? (b) How can we reconcile systematic use of rules with variable use of strategies? (c) When do children begin to use rules? and (d) How do children generate new rules? In this Reflection, we summarize current understanding of development of knowledge about balance scales and consider each of the four questions.     

Relating print and speech: the effects of letter names and word position on reading and spelling performance

From an early age, children can go beyond rote memorization to form links between print and speech that are based on letter names in the initial positions of words (Treiman & Rodriguez, 1999; Treiman, Sotak, & Bowman, 2001). For example, children's knowledge of the name of the letter t helps them learn that the novel word TM is pronounced as team. Four experiments were carried out to determine whether letter names at the ends of words are equally useful. Four- and five-year-olds derived little benefit from such information in reading (Experiments 1 and 3) or spelling (Experiment 2), although adults did (Experiment 4). For young children, word-final information appears to have less influence on reading and spelling performance than does word-initial information. The results help delineate the circumstances under which children can go beyond a logographic approach in learning about print.     

Developmental and content effects in reasoning with causal conditionals

Two predictions derived from Markovits and Barrouillet's (2001) developmental model of conditional reasoning were tested in a study in which 72 twelve-year-olds, 80 fifteen-year-olds, and 104 adults received a paper-and-pencil test of conditional reasoning with causal premises ("if cause P then effect Q"). First, we predicted that conditional premises would induce more correct uncertainty responses to the Affirmation of the consequent and Denial of the antecedent forms when the antecedent term is weakly associated to the consequent than when the two are strongly associated and that this effect would decrease with age. Second, uncertainty responding to the Denial of the antecedent form ("P is not true") should be easier when the formulation of the minor premise invites retrieval of alternate antecedents ("if something other than P is true"). The results were consistent with the hypotheses and indicate the importance of retrieval processes in understanding developmental patterns in conditional reasoning with familiar premises.     

The Late Life Reconstruction of Selfhood Analyzed in Peter Hall's Film She's Been Away

The film She's Been Away tells the story of an old woman who had been locked in a mental asylum while a teenager, for willfully violating repressive sexual codes. Sixty years later her ward is closed and she moves in with her nephew and his wife. Faced with what appears to be a hopeless situation, she manages to forge a sense of a meaningful closure to a misspent life. Through narrative, story structure, and characterization the film throws into focus coping mechanisms and ego strategies deployed by a triple disadvantaged person (woman, old, and mad) in her ascent to a reconstructed selfhood. As the protagonist ties both ends of her life, and faces the abyss in between she makes genuine adaptive use of so-called regressive, late-life development assets (available to a lesser degree to elderly people in normal life circumstances), primarily the abolition of linear time. Through this abolition she makes reminiscing an actual reality while still maintaining a functional separation between the real and the remembered. Her portrayal is a valuable document for gerontologists as it explores, through artistic imagination and intuition, the workings of an aging mind in search for a meaningful sense of closure.     

Early Developmental Precursors of Externalizing Behavior in Middle Childhood and Adolescence

This study examined the infancy- and toddler-age precursors of children's later externalizing problem behavior. Risk constructs included suboptimal patterns of observed caregiver-child interaction and the caregiver's perception of child difficultness and resistance to control. In addition, a novel dimension of caregiver-child relationship quality, the caregiver's perception of her toddler's unresponsiveness to her, was examined as a possible precursor of children's externalizing behavior. Externalizing problem outcomes were assessed throughout the school-age period and again at age 17, using multiple informants. As toddlers, children at risk for later externalizing behavior were perceived as difficult and resistant to control, and relationships with their caregivers were relatively low in warmth and affective enjoyment. Finally, the caregiver's perception of her toddler as emotionally unresponsive to her was a consistent predictor of later externalizing behavior, suggesting that negative maternal cognitions associated with child conduct problems may begin in toddlerhood. These predictive patterns were similar for boys and girls, and with minor exceptions, generalized across different subdimensions of externalizing problem behavior. Our findings underscore the importance of the infancy and toddler periods to children's long-term behavioral adjustment, and indicate the desirability of further research into the nature of caregivers' early perceptions of child unresponsiveness.     

Global Progress I: Empirical Evidence for ongoing Increase in Quality-of-life

This paper argues that both the relativist and the pessimist critiques of the idea of progress are inadequate. Progress is defined as increase in global quality of life (QOL). Such QOL is intrinsically subjective, but not relative. It can be reliably measured through life satisfaction-type questions. The World Database of Happiness provides extensive data on social, economic and psychological factors that correlate with overall QOL. They include wealth, health, security, knowledge, freedom and equality. Various statistical data suggest that all these QOL indicators have undergone significant improvements during the last half century, in most of the world. This gives strong support to the thesis that progress objectively occurs.     

The cognitive foundations of reading and arithmetic skills in 7- to 10-year-olds

A range of possible predictors of arithmetic and reading were assessed in a large sample (N=162) of children between ages 7 years 5 months and 10 years 4 months. A confirmatory factor analysis of the predictors revealed a good fit to a model consisting of four latent variables (verbal ability, nonverbal ability, search speed, and phonological memory) and two manifest variables (digit comparison and phoneme deletion). A path analysis showed that digit comparison and verbal ability were unique predictors of variations in arithmetic skills, whereas phoneme deletion and verbal ability were unique predictors of variations in reading skills. These results confirm earlier findings that phoneme deletion ability appears to be a critical foundation for learning to read (decode). In addition, variations in the speed of accessing numerical quantity information appear to be a critical foundation for the development of arithmetic skills.     

A Review of the Effects of Interspersing Procedures on the Stages of Academic Skill Development

Basic and applied research related to the effects of interspersing trials of maintenance (i.e., review) tasks among trials of acquisition tasks on academic skill development is reviewed. In general, empirical research suggests that interspersing procedures are effective in facilitating acquisition, learning rate, and maintenance. However, some inconsistency exists among the data that suggests student learning, in some instances, may be impeded. Research also suggests that interspersing procedures are not conducive to facilitating generalization. The discrepancy between various research findings and the consistent failure of research on interspersing procedures to increase generalization is critically reviewed in relation to a hierarchical learning theory set forth by Haring and Eaton (1978). From this hierarchical learning theory perspective, inconsistent results may be better understood and predicted. Implications for current practice and directions for future research are also discussed.
