学前期儿童执行功能和语言的双向关系:社会经济地位的调节

采用追踪研究考察258名学前儿童执行功能与语言的双向关系,及二者关系是否受社会经济地位调节。交叉滞后结果表明,学前儿童语言发展与执行功能三个子成分（抑制控制、认知灵活性、工作记忆）存在双向关系;T1时儿童语言对T2时认知灵活性的预测作用受家庭社会经济地位调节：在高社会经济地位家庭中,T1时间儿童的语言能显著正向预测T2时认知灵活性,低社会经济地位家庭中预测作用不显著;其余双向关系中调节作用均不显著。本研究表明,学前儿童执行功能三个子成分与语言均存在双向关系,且社会经济地位在部分关系中起到调节作用。     

学前儿童睡眠问题与语言障碍的关系

睡眠是个体身心健康发展的重要保障。学前期的睡眠问题可能会对儿童的行为、认知、语言和健康等诸多方面产生负面影响。研究表明, 睡眠呼吸障碍、夜间睡眠不足以及入睡困难等睡眠问题是学前儿童语言障碍的潜在威胁性因素。学者们提出了睡眠记忆巩固假说、警觉性假说和突触稳态假说来解释睡眠问题影响学前儿童语言发展的内在机制。这些研究结果为语言障碍的早期干预提供了一种新思路, 即通过行为干预、药物治疗、手术治疗和游戏干预等睡眠问题干预方式来提高学前儿童的语言能力。未来的研究可以进一步深入分析睡眠问题与语言障碍相关联的内在机制, 了解不同年龄段儿童睡眠问题与语言能力的关系, 以及探究融合教育背景下有效的游戏干预方式。     

Teaching letter sounds to kindergarten English language learners using incremental rehearsal

Proficiency in letter–sound correspondence is important for decoding connected text. This study examined the effects of an evidence-based intervention, incremental rehearsal (IR), on the letter–sound expression of three kindergarten English language learners (ELLs) performing below the district benchmark for letter–sound fluency. Participants were native speakers of Hmong, Spanish, and Polish. A multiple-baseline design across sets of unknown letter sounds was used to evaluate the effects of IR on letter–sound expression. Visual analysis of the data showed an increase in level and trend when IR was introduced in each phase. Percentage of all non-overlapping data (PAND) ranged from 95% to 100%. All participants exceeded expected growth and reached the spring district benchmark for letter–sound fluency. Results suggest that IR is a promising intervention for increasing letter–sound expression for ELLs who evidence delays in acquiring letter sounds.     

Early communicative gestures and play as predictors of language development in children born with and without family risk for dyslexia

The present study investigated early communicative gestures, play, and language skills in children born with family risk for dyslexia (FR) and a control group of children without this inheritable risk at ages 12, 15, 18, and 24 months. Participants were drawn from the Tromsø Longitudinal study of Dyslexia (TLD) which follows children's cognitive and language development from age 12 months through Grade 2 in order to identify early markers of developmental dyslexia. Results showed that symbolic play and parent reported play at age 12 months and communicative gestures at age 15 months explained 61% of the variance in productive language at 24 months in the FR group. These early nonlinguistic measures seem to be potentially interesting markers of later language development in children born at risk for dyslexia.     

Towards a relational framework for pathological gambling (Part I): Five circuits

Relationship patterns before and after pathological gambling were investigated qualitatively using eight in‐depth clinical case studies in which one partner met Diagnostic and Statistical Manual of Mental Disorders‐IV pathological gambling criteria. Five circuits of couple interactions are described: (i) fault‐lines; (ii) pressure points; (iii) escalation; (iv) relapse and (v) congruence. The exploration of these circuits is developed in two complementary articles. This first article delineates the first four circuits as recursive self‐perpetuating cycles of couple distress in systemic interaction with pathological gambling development and relapse. The second article delineates how a couple can be helped to extricate themselves from these recursive circuits through ‘congruence’. Implications of this relational formulation of pathological gambling for conceptualization, assessment and treatment are discussed.     

Children,childhood, and development in evolutionary perspective

We examine children, childhood, and development from an evolutionary perspective. We begin by reviewing major assumptions of evolutionary–developmental psychology, including the integration of “soft” developmental systems theory with ideas from mainstream evolutionary psychology. We then discuss the concept of adaptive developmental plasticity and describe the core evolutionary concept of developmental programming and some of its applications to human development, as instantiated in life history theory and the theory of differential susceptibility to environmental influence. We then discuss the concept of adaptation from an evolutionary–developmental perspective, including ontogenetic and deferred adaptations, and examine the development of some adaptations of infancy and childhood from the domains of folk psychology and folk physics. We conclude that evolutionary theory can serve as a metatheory for developmental science.     

Stepping Into a Map: Initial Heading Direction Influences Spatial Memory Flexibility

Learning a novel environment involves integrating first‐person perceptual and motoric experiences with developing knowledge about the overall structure of the surroundings. The present experiments provide insights into the parallel development of these egocentric and allocentric memories by intentionally conflicting body‐ and world‐centered frames of reference during learning, and measuring outcomes via online and offline measures. Results of two experiments demonstrate faster learning and increased memory flexibility following route perspective reading (Experiment 1) and virtual navigation (Experiment 2) when participants begin exploring the environment on a northward (vs. any other direction) allocentric heading. We suggest that learning advantages due to aligning body‐centered (left/right/forward/back) with world‐centered (NSEW) reference frames are indicative of three features of spatial memory development and representation. First, memories for egocentric and allocentric information develop in parallel during novel environment learning. Second, cognitive maps have a preferred orientation relative to world‐centered coordinates. Finally, this preferred orientation corresponds to traditional orientation of physical maps (i.e., north is upward), suggesting strong associations between daily perceptual and motor experiences and the manner in which we preferentially represent spatial knowledge.
