Infants’ vocalizations at 6 months predict their productive vocabulary at one year

Long before their first words, children communicate by using speech-like vocalizations. These protophones might be indicative of infants’ later language development. We here examined infants’ (n = 56) early vocalizations at 6 months (vocal reactivity scale of the IBQ-R) as a predictor of their expressive and receptive language at 12 months (German version of the CDI). Regression analyses revealed vocalizations to significantly predict expressive, but not receptive language. Our findings in German-learning 6-month-olds extend previous predictive evidence of early vocalizations reported for older infants. Together these findings are informative in light of early assessments monitoring typical and atypical language development.     

父母学业参与、父母学业压力与青少年早期的学业投入:有调节的中介模型

为探讨父母学业参与和学业压力与青少年早期学业投入之间的关系,考察成就目标取向的中介作用,以及学业成就水平在该中介过程中的调节作用,对2487名初一学生进行测查,结果发现：（1）父母学业参与正向预测青少年早期个体的学业投入、负向预测学业抽离,父母学业压力正向预测学业抽离;（2）掌握目标取向在父母学业参与和青少年早期的学业投入之间起正向中介作用,在父母学业参与和学业抽离间发挥负向中介作用;表现回避目标取向在父母学业压力和学业抽离间具有正向中介作用;（3）掌握目标取向的中介作用受到学业成就水平的调节。研究结果揭示了父母学业参与和学业压力对青少年早期的学业投入的共同作用,为从家庭层面提高青少年的学业投入水平提供了参考。     

The Persistence of Priming: Exploring Long-lasting Syntactic Priming Effects in Children and Adults

The implicit learning account of syntactic priming proposes that the same mechanism underlies syntactic priming and language development, providing a link between a child and adult language processing. The present experiment tested predictions of this account by comparing the persistence of syntactic priming effects in children and adults. Four-year-olds and adults first described transitive events after hearing transitive primes, constituting an exposure phase that established priming effects for passives. The persistence of this priming effect was measured in a test phase as participants described further transitive events but no longer heard primes. Their production of passives was compared to a baseline group who described the same pictures without any exposure to primes. Neither immediate nor long-term priming effects differed between children and adults but both children and adults showed significant immediate and persistent effects of the priming when the test phase occurred immediately after the exposure phase and when a short delay separated the exposure and test phase. The implications of these results for an implicit learning account of syntactic priming are discussed.     

Dynamics Versus Development in Numerosity Estimation: A Computational Model Accurately Predicts a Developmental Reversal

Perceptual judgments result from a dynamic process, but little is known about the dynamics of number-line estimation. A recent study proposed a computational model that combined a model of trial-to-trial changes with a model for the internal scaling of discrete numbers. Here, we tested a surprising prediction of the model—a situation in which children's estimates of numerosity would be better than those of adults. Consistent with the model simulations, task contexts led to a clear developmental reversal: children made more adult-like, linear estimates when to-be-estimated numbers were descending over trials (i.e., backward condition), whereas adults became more like children with logarithmic estimates when numbers were ascending (i.e., forward condition). In addition, adults’ estimates were subject to inter-trial differences regardless of stimulus order. In contrast, children were not able to use the trial-to-trial dynamics unless stimuli varied systematically, indicating the limited cognitive capacity for dynamic updates. Together, the model adequately predicts both developmental and trial-to-trial changes in number-line tasks.     

Processus d’élaboration et de validation d’un questionnaire portant sur le développement des compétences émotionnelles lors du mentorat

Objective and methodThe aim of this article is to provide a portrait of the emotional competencies developed by school principals (n = 359) in a mentoring context by developing a seven-step questionnaire by Frenette et al. (2019) presenting various proofs of validity.ResultsThe analyses conducted support a factorial structure with two correlated aspects of emotional competencies (self and others). School principals in Quebec develop more emotional competencies related to the aspect of others than for themselves during mentoring. A further analysis indicates that school principals develop more two dimensions of Emotional competencies: Identification and Understanding. The results also show that 77.26 % of respondents indicated that they developed emotional skills during mentoring.ConclusionThe results provided an understanding of the importance of emotional competencies in education, and specifically in school management. It also revealed the importance of emphasizing the role of mentoring in their development. To our knowledge, the questionnaire developed in this study is one of the first to measure the development of emotional competencies during a mentoring relationship.     

Bridging ears and eyes when learning spoken words: On the effects of bilingual experience at 30 months

From the very first moments of their lives, infants selectively attend to the visible orofacial movements of their social partners and apply their exquisite speech perception skills to the service of lexical learning. Here we explore how early bilingual experience modulates children's ability to use visible speech as they form new lexical representations. Using a cross‐modal word‐learning task, bilingual children aged 30 months were tested on their ability to learn new lexical mappings in either the auditory or the visual modality. Lexical recognition was assessed either in the same modality as the one used at learning (‘same modality’ condition: auditory test after auditory learning, visual test after visual learning) or in the other modality (‘cross‐modality’ condition: visual test after auditory learning, auditory test after visual learning). The results revealed that like their monolingual peers, bilingual children successfully learn new words in either the auditory or the visual modality and show cross‐modal recognition of words following auditory learning. Interestingly, as opposed to monolinguals, they also demonstrate cross‐modal recognition of words upon visual learning. Collectively, these findings indicate a bilingual edge in visual word learning, expressed in the capacity to form a recoverable cross‐modal representation of visually learned words.     

Dynamic relationships between phonological memory and reading: A five year longitudinal study from age 4 to 9

We reconcile competing theories of the role of phonological memory in reading development, by uncovering their dynamic relationship during the first 5 years of school. Phonological memory, reading and phoneme awareness were assessed in 780 phonics‐educated children at age 4, 5, 6 and 9. Confirmatory factor analyses demonstrated that phonological memory loaded onto two factors: verbal short‐term memory (verbal STM; phonological tasks that loaded primarily on serial order memory) and nonword repetition. Using longitudinal structural equation models, we found that verbal STM directly predicted early word‐level reading from age 4 to 6, reflecting the importance of serial‐order memory for letter‐by‐letter decoding. In contrast, reading had no reciprocal influence on the development of verbal STM. The relationship between nonword repetition and reading was bidirectional across the 5 years of study: nonword repetition and reading predicted each other both directly and indirectly (via phoneme awareness). Indirect effects from nonword repetition (and verbal STM) to reading support the view that phonological memory stimulates phonemically detailed representations through repeated encoding of complex verbal stimuli. Similarly, the indirect influence of reading on nonword repetition suggests that improved reading ability promotes the phoneme‐level specificity of phonological representations. Finally, the direct influence from reading to nonword repetition suggests that better readers use orthographic cues to help them remember and repeat new words accurately.

空间交互研究新视角：多重社会因素的影响

空间交互是人类生存和社交的重要内容, 主要包括语言交流和视角采择两大范畴。对空间交互策略和效率的影响因素的研究, 传统上集中于空间因素, 近年来逐渐开始关注各种社会因素, 包括个体自身的社会认知特质、交互对象的社会属性和空间环境中的社会线索, 并从不同角度提出了理论解释。未来研究应关注社会认知与空间认知的跨领域融合, 考察更加多元的空间交互对象, 最终建立一个整合空间和社会因素的空间交互理论框架。     

化危为机：青少年学校转折期的过渡

从生命历程的角度看, 学校过渡是青少年成长过程中的重要发展转折点, 对个体的发展轨迹具有重要影响。先前研究多基于缺陷的视角, 将学校过渡视为充满挑战和风险的危机时期, 并发现青少年在这一时期伴随着各种消极的发展结果。但从青少年积极发展的视角来看, 学校过渡可能是青少年获得适应性的、健康发展的重要机遇, 也是发展可塑性表现最为充分的时期。如果青少年的内部和外部资源能够很好的融合, 他们就有可能获得积极的学校过渡。
