Appraisal in Young Children’s Friendship Conversations: How Young Friends Establish Common Ground, Negotiate Relationships, and Maintain Play

Brain Mechanisms in Early Language Acquisition

Biliteracy and Second-Language Learners

Common ground (CG)-a pragmatic capability that reflects the construction of shared meaning by two interlocutors during conversation-is widely accepted as crucial for effective communication, but its exploration has been limited in the context of children's peer-to-peer interaction. Specifically, this study aimed to explore CG differences between typically developing (TD) and autistic populations, CG's developmental trajectories, as well as the link between CG and motor coordination skills during peer interactions. Study participants included 148 children (6-16 years), comparing 64 TD and 84 autistic children across three age levels. Fixed dyads matched on IQ, age, sex, and mother's education performed a CG tangram-card task and complementary joint action (JA) tasks to evaluate peer-to-peer movement coordination. Individual motor skills were also assessed. As expected, both autistic and TD groups showed increasing efficacy over the 6-turn CG task (fewer words and shorter duration to communicate), although autistic participants were less efficient than TD participants. Better motor skills and JA synchronization correlated with both groups' more efficient CG performance. Additionally, the indirect relationship between group (TD/autism) and CG was mediated by motor skills and JA, with age moderating the relationship between JA and CG. Specifically, better motor skills and socio-motor coordination were associated with more efficient CG creation, particularly in younger children (under 10years). These findings suggest potential novel avenues for early interventions targeting motor and language challenges in autism to enhance pragmatic abilities and peer interactions, offering insights into language development in this population.

Digitods: Toddlers, Touch Screens and Australian Family Life

Reading storybooks with children, often referred to as early storybook reading (ESR), is considered among the most important activities parents can undertake to strengthen their children’s language and literacy development. The evidence in favour of ESR for supporting language development with toddlers, preschool, and primary school children is well documented. Given the positive improvements that have been reported from ESR with preschool and primary school children, further examination is warranted to investigate whether these benefits can be observed with even younger children as well as children who are at risk of language and social communication difficulties, such as babies with a hearing loss (HL). The research presented in this thesis examined the effectiveness of ESR with babies with and without a HL using a range of methodologies over four phases. Consistent with previous research with older children, it was hypothesised that ESR would be effective with babies with and without a HL for strengthening spoken language and social communication skills. In Phase 1, the home reading practices and values regarding ESR of parents with normal hearing (NH) babies and young children was examined using a questionnaire. Families (n = 113) from both a less advantaged socioeconomic area and more advantaged socioeconomic area participated. Analysis of the results revealed that parents appeared to value ESR and engaged in regular storybook reading with their children. Differences between the less advantaged area and more advantaged area were observed for frequency of ESR. Parents from both areas also indicated difficulties with selecting age appropriate books for babies and young children and creating a reading environment that promoted early language and social communication learning. The information from Phase 1 was used to develop an ESR intervention that was provided in the second phase of this thesis. In Phase 2, an ESR intervention was delivered to parents with NH babies (3-to 12-months-of-age) to examine the effectiveness of a high and low intensity ESR intervention to support parent-child interactions to strengthen language and social communication development. A pre-test, post-test comparison group design was conducted. The parents were allocated into two intervention conditions: a high intensity intervention group (n = 17) and a low intensity intervention group (n = 15). The findings suggested that ESR was effective for promoting language and broader social communication development for both groups. However, the high intensity group presented with significantly higher language and broader social communication scores with a large effect size immediately following the intervention, and the scores continued to be significantly higher than the low intensity group when the children were tested at 2-years-of-age. Following the findings from Phase 2, the high intensity ESR intervention was then trialled in Phase 3, with parents (n = 4) of babies (aged 9- to 15-months-of-age) with a HL, who are vulnerable to spoken language and social communication difficulties. All of the babies had a permanent HL and used hearing aids or cochlear implants. Using a multiple baseline single case experimental design across behaviours, the effectiveness of the ESR intervention for strengthening parents’ book selection skills, parent-child eye-contact/joint attention, and parent-child turn taking was investigated. Examination of the results revealed that ESR was effective for strengthening parent-child eye-contact/joint attention and parent-child turn taking for all four parent-baby dyads with a large effect size. However, ceiling effects for parents’ book selection skills were observed. The results provided preliminary evidence in favour of the ESR intervention with parents of babies with a HL and highlighted the need for future research to investigate the home reading practices and values regarding ESR of parents with babies and young children with a HL. Further examination of the home reading practices and values regarding ESR of parents with babies and young children with a HL was conducted in Phase 4 using a questionnaire. Following on from Phase 1, the same questionnaire that was provided to parents with NH babies and young children was trialled with parents (n = 12) with babies and young children with a HL (aged from less than 3-months-of-age to 3-yearsof- age). The findings suggested that parents with babies and young children with a HL valued ESR and read with their children frequently. Parents reported limited attendance at libraries and bookstores and demonstrated difficulties with book selection and using a seating position that created opportunities for eye-contact/joint attention and turn taking. Together, the four phases presented in this thesis advance our knowledge of ESR with babies and young children with and without a HL, facilitating a more holistic and comprehensive understanding of ESR. Consistent with our hypothesis, the studies presented in this thesis provide evidence for the effectiveness of ESR for strengthening spoken language and social communication skills for babies with and without a HL. The significance of these findings and clinical relevance is highlighted.

How do very young children use talk to create relationship? Are there associations between the quality of children’s relationships and their language use? Do children’s pragmatic abilities relate to other language competencies? This qualitative study addresses these questions using naturalistic data from a daycare setting by looking at the spontaneous peer talk in two overlapping dyads of toddler girls. This analysis indicates that young children have considerable pragmatic skill in using talk to create and maintain relationship. Children’s relational style and language use seem closely connected: the different talk styles of the two dyads instantiate and support their distinct relational styles. Further, different styles of relational talk appear to tap different language abilities. Considered with other studies looking at young children’s language and particularly pragmatic skills, this analysis suggests that young children’s language capabilities in the context of specific relationships merit further attention.

Now in its fourth edition, this textbook provides a chronological account of first language acquisition, showing how young children acquire language in their conversational interactions with adult speakers. It draws on diary records and experimental studies from leaders in the field to document different stages and different aspects of what children master. Successive chapters detail infants' and young children's progression from attending to adult faces, gaze, and hand motions, to their first attempts at communicating with gaze and gesture, then adding words and constructions. It comprehensively covers the acquisition of the core areas of language – phonetics and phonology, lexicon, grammar and sentence structure, and meaning – as well as how children acquire discourse and conversational skills. This edition includes new sections on how children build 'common ground' with adults and other children, individual differences in children's language development, how they collaborate with adults in constructing utterances, and how they qualify beliefs.

Pratt Google Scholar More articles by this author https://doi.org/10.1044/leader.FTR2.10042005.8 SectionsAbout ToolsAdd to favorites ShareFacebookTwitterLinked In It is well known that the development of speech is extremely limited without adequate auditory input and feedback. An obvious example is that hearing loss in infancy and early childhood usually affects all as pects of speech production unless there is early and consistent use of sensory aids as well as substantive sensorimotor and linguistic training. The speech development of infants and children with hearing loss hinges on their abilities to use audition not only to learn the sounds of their language, but also to use their articulators to produce those sounds and make use of auditory feedback to refine their speech over time. As such, the speech of children with prelingual hearing loss is particularly susceptible to delay and disorder, es pecially if the severity of the hearing loss is substantial and intervention is delayed or inadequate. Speech Development During the first six months of life (and possibly in utero) auditory perceptual learning is vital for acquiring oral language and speech, although the maturation timeline for the speech production in normal-hearing children is relatively lengthy. This protracted timeline may account for the long-term training and treatment needs of many children with hearing loss, even those identified and fitted early with sensory aids (Yoshinaga-Itano & Sedey, 2000). Young children with normal hearing typically begin babbling around 5–6 months of age and start verbal expression around 12 months of age. However, their speech production skills continue to be refined through the school-age years and well beyond when their basic phonological inventories have been established. For example, vowel space, voice-onset times, and vocal control adjust throughout early childhood (Assmann & Katz, 2000; Koenig, 2001; Lee, Pontamianos, & Naray anan, 1999). Furthermore, substantial acoustic variability is a hallmark of children’s speech production until late childhood. Although the research is somewhat mixed on the development of coarticulation, children appear to be less able than adults to coarticulate their speech gestures in a consistent manner, and as a consequence, their speech is less intelligible than that of adults (Katz, Kripke, & Tallal, 1991; Nittrouer, 1993). The refinement of auditory processing of speech has a similar developmental timeline. Child ren may apply different rules or weights to speech cues than adults, and these weights change throughout childhood (Nittrouer, 2003; Nit trouer, Crowther, & Miller, 1998). Their auditory processing of speech also appears to be more susceptible to acoustic and linguistic perturbations than is observed with adults. Children are more adversely affected than adults by background noise, reverberation, talker variability, re ductions in signal bandwidth, and the number of signal channels (Eisenberg et al., 2000; Ryalls & Pisoni, 1997; Kortekaas & Stelmachowicz, 2000). The Role of Audition in Speech Development and Production For mature speakers, audition acts as an error detector and a means of monitoring speaking conditions. It is considered to be slower than other forms of sensory information (i.e., proprioception) generated during speech, and therefore is likely limited to a feedback role (Perkell et al., 1997). Speakers use audition to determine if their articulators have produced sounds that are acoustically off-target. Audition also provides information for corrective adjustments, and as a consequence, is a contributor to the maintenance of speech integrity. Studies of frequency and spectrally shifted speech feedback have shown that adults rapidly adjust to minor acoustic perturbations with compensatory and/or matching strategies (Bauer & Larson, 2003; Houde & Jordan, 2002; Jones & Munhall, 2002, 2003). They appear to adjust their articulators so that their speech productions match their internal representations. In addition to acting as an error detector, hearing is used by mature speakers to determine how they should adjust their speech in various acoustic, linguistic, and social environments. For example, adults know when to speak slower, louder, softer, or more precisely in order to accommodate their listener or the environmental conditions (Perkell et al., 1997). In contrast, many young children are unable to adjust the clarity of their speech, even when explicitly directed to do so (Ide-Helvie et al., 2004). Audition also allows the development of articulatory organization by providing information about how to position, move, and coordinate the articulators for speech, movements that can differ from those associated with vegetative functions of the mechanisms (Moore & Ruark, 1996). For ex ample, infants use audition to learn how to shift from a vegetative breathing pattern to a pattern that can support speech. They learn how to position and move their tongues and to judge the acoustic consequences of those gestures. Coord ination of the larynx with the vocal tract and upper airway articulators is refined over years but requires an intact auditory system (Koenig, 2001; Tye-Murray, 1992). The lip and jaw movements associated with speech in infants and young children are highly variable but distinct from sucking, chewing, and smiling (Green et al., 2000; Green, Moore, & Reilly, 2002; Moore & Ruark, 1996). The implication is that although the same peripheral mechanisms are used across oral and respiratory functions, the differing goals require substantially distinct coordination and feedback efforts. The coordination needed to chew and swallow efficiently develops over early childhood but is largely independent of hearing, whereas the coordination required to move between vowel and consonant gestures, particularly in a coordinated and coarticulated manner, is strongly influenced by hearing (Baum & Waldstein, 1991; Guenther, 1995; Tye-Murray, 1992; Waldstein & Baum, 1991). Audition has a primary sensorimotor role in the development of speech, but it also is fundamental to infants and young children learning the sounds of their language. Furthermore, it helps them learn how specific speech events relate to their phonology, so that with development, young children become more able to use their hearing to inform them about the sequencing of speech gestures and the correctness of subsequent productions. Over time children learn to use audition to monitor ongoing speech, detect errors, and make corrective adjustments. Hearing Loss and Speech Production Hearing loss is common in the general population but its effects on speech production are most pronounced with individuals whose hearing loss is congenital or acquired in early childhood. Most adults who acquire their hearing losses later in life suffer little or no deterioration in intelligibility, likely because their residual hearing provides sufficient feedback since their mature speech production systems rely more on orosensory than auditory information to maintain proper control (Guenther, 1995; Goehl & Kaufman, 1984; Perkell et al., 1997). The speech differences that they do exhibit are subtle and usually imperceptible, even in cases of complete or nearly complete adventitious hearing loss. Nonetheless, some adventitiously deafened adults exhibit reduced speaking rate, and compromised articulatory and phonatory precision (Kishon-Rabin et al., 1999; Lane & Webster, 1991; Lane et al., 1995; Leder et al., 1987; Waldstein, 1990; Perkell et al., 1992). These speech differences are similar in nature, but not in severity, to those observed with prelingually deafened speakers. Most infants and young children with hearing loss demonstrate disordered phonation and articulation, as well as delays in the acquisition of sound categories. The entire speech production system can be affected, from respiratory support to the coarticulation of ongoing speech (Pratt & Tye-Murray, 1997). This is especially true if the hearing loss is identified late or after a period of protracted hearing loss. Furthermore, the overlap and interaction of disordered sound production and linguistic delay contribute to poor speech integrity and restricted speech development. Babbling generally does not appear before 12 months of age (Oller & Eilers, 1988; Oller et al., 1985) and canonical babbling has been observed as late as 31 months in this population (Lynch, Oller, & Steffens, 1989). Infants also produce fewer instances of canonical babble and include a more limited range of consonants in their babble (Stoel-Gammon, 1988; Stoel-Gammon & Otomo, 1986; Wallace, Menn, & Yoshinaga-Itano, 2000). However, later speech intelligibility is better predicted by the consonant inventory used in emerging spoken language during the second year of life than during babble (Obenchain, Menn, & Yoshinaga-Itano, 2000). The phonetic repertoires of infants with severe-to-profound hearing loss often are restricted when compared to their normal-hearing peers, although there is abundant individual variability (Lach, Ling, Ling & Ship, 1970; Stoel-Gammon & Otomo, 1986; Wallace et al., 2000; Yoshinaga-Itano & Sedey, 2000). The early speech inventories of infants with severe-to-profound hearing loss predominately consist of motorically easy sounds such as vowels and bilabial consonants. The sounds of their inventories also contain more low frequency information, which is more audible. For example, the babbling of infants with hearing loss often has a high concentration of nasals and glides, which include low-frequency continuant cues (Stoel-Gammon & Otomo, 1986). Without early intervention and appropriate fitting of sensory aids the speech-sound inventories of many children with hearing loss usually do not attain full maturity. Yoshinaga-Itano and Sedey (2000) found that children with moderate-to-severe hearing losses did not reach an age-appropriate complement of vowel and consonant sounds until about 4 and 5 years respectively, and many children with profound hearing loss had restricted inventories even at 5 years of age. Children with profound hearing loss often reach an early plateau in their speech skill development. For instance, the speech characteristics of many children with severe-to-profound hearing loss demonstrate little improvement in sound inventory and intelligibility after 8 years of age, even with the initiation of extensive training (Hudgins & Number, 1942, McGarr, 1987; Smith, 1975). Such results imply that, like auditory and language interventions, speech production therapy should be an important component of early intervention, and that the common practice of delaying speech training in children with hearing loss until they have functional language is developmentally untenable if the goal is for them to be oral communicators. In addition to the relationship between age-of-onset and speech impairment severity, there also is a moderately positive relationship between the severity of hearing loss and the extent of the associated speech difficulties (Boothroyd, 1969; Levitt, 1987; Smith, 1975). For example, children with mild-to-moderate hearing loss, particularly if well aided, tend to exhibit speech differences that are mild (Elfenbein, Hardin-Jones, & Davis, 1994; Oller & Kelly, 1974; West & Weber, 1973). Elfenbein and colleagues found that children with mild-to-moderate hearing loss exhibit good intelligibility but had higher than normal rates of affricate and fricative substitutions. Mild hoarseness and resonance problems also are present in 20% to 30% of this group of children. Moreover, they tend to have increased rates of voicing irregularities, difficulties with /r/ production, and omissions of back and word-final consonants. Early studies of children with profound prelingual hearing loss showed that most rarely acquired speech skills sufficient to interact easily using spoken language. On average, less than 20% of their words were intelligible to listeners who were not familiar with their speech (Hidgins & Numbers 1942; Markides, 1970; Smith, 1975). Smith (1975) evaluated 40 children with varying levels of hearing loss and, on average, only 18.7% (0% to 76%) of their words could be identified by inexperienced listeners. As expected, overall intelligibility was inversely related to the frequency of segmental and suprasegmental errors. However, with early identification of hearing loss and early intervention (i.e., fitting of sensory devices, behavioral training, and parent counseling), the numbers of children with severe-to-profound hearing loss and intelligible speech has increased (Uchanski & Geers, 2003). Many more children are developing sufficient speech perception to support development of speech production and oral language, but these advances may have added to the overall heterogeneity of the population (Higgins et al., 2003). Other factors contribute to the diversity of speech production skills observed with these children. For instance, cognitive skill (particularly nonverbal intelligence) has been found to be an important predictor of functional speech and oral language in children with hearing loss (Geers et al., 2002; Tobey et al., 2003). Auditory experience in infancy and early childhood, even of limited duration, positively influences the speech production skills of children who have severe-to-profound hearing loss (Geers, 2004). The use of sensory aids has a substantial impact on speech outcomes, but somewhat surprisingly, the age at which infants and young children are fitted with cochlear implants has not surfaced in studies of speech production as a significant predictor of later speech intelligibility (Geers et al., 2002; Tobey et al., 2003). Early implantation (less than 2 years) is, however, related to more normal oral communication development as a whole (both speech and oral language) (Geers, 2004). It may be that the age of implantation is not easily separated from other influences of intervention, like the orientation of the habilitation program and parent involvement, which relate strongly to children being auditory perceptual learners and users of auditory feedback. Another consideration is that many early-implanted children may be implanted too late to observe a clear impact on speech production. The critical ages at which hearing aids should be fitted has not been investigated, but like cochlear implants, it is assumed that earlier is better. The oromotor integrity and language skills are additional factors that often are neglected in studies of speech development in children with hearing loss. A substantial number of infants and children with hearing loss present with secondary handicapping conditions, such as neurological disorders. When these neurological disorders include the speech mechanism, the development of functional speech is difficult even if audition is optimized. As such, is it not unusual for a child with hearing loss to have a coexisting dysarthria along with the speech impairment secondary to the hearing loss. A subset of children with hearing loss also may have an apraxia of speech, but separating the impact of hearing loss from an apraxia of speech is difficult because the associated speech characteristics overlap (McNeil, Robin & Schmidt, 1997). Language disorders also are commonly observed in children with hearing loss, and are frequently evidenced in phonological disorder and lexical delay. As a result, extricating the sensorimotor impact of hearing loss on speech production from the influences of language disorder in individual children is not always straightforward (Peng et al., 2004). Habilitation: Sensory Aids and Treatment Most speech training approaches are dependent on optimizing the use of residual hearing although some approaches use other modalities (Pratt, Heintzelman, & Deming, 1993; Pratt & Tye-Murray, 1997). Correspondingly, it is generally believed that speech is learned most easily if infants and children learn and monitor their speech through their auditory systems. Therefore, the proper and early fitting, and consistent use of sensory aids, along with auditory and language training are important components of speech production training. In support of this auditory-based approach is the relationship between the severity of prelingual hearing loss and the extent of speech delay/disorder found in children (Boothroyd, 1969; Levitt, 1987; Smith, 1975), as well as any history of previous hearing (Geers, 2004). The relationship between audiometric configuration and speech intelligibility also argues for the importance of audition if the goal for a child is oral communication (Levitt, 1987; Osberger, Maso, & Sam, 1993). There is a growing literature supporting the positive impact of cochlear implants on speech development, as well as the role that auditory-oral-based training programs play in communication outcomes of children fitted with cochlear implants (Geers et al., 2002; Tobey et al., 2003). There is, however, limited efficacy data for children with less severe hearing loss who are typically fitted with hearing aids. The lack of research in this area is glaring because wearable electroacoustic hearing aids have been available for more than 50 years (Lybarger, 1988) and are a fundamental component of treatment approaches for most children with hearing loss. Furthermore, more infants and children are fitted with hearing aids than cochlear implants. Preliminary data reported by Stemachowicz and her colleagues (2004) on three infants fitted early with hearing aids suggested delays in sound category acquisition consistent with patterns previously reported in the literature. Sound inventories were impoverished, consonants were more affected than vowels, and sound containing high-frequency cues were particularly limited. Additional data by Pittman and colleagues (2003) observed that the amplitude of high-frequency speech cues directed to and produced by children wearing hearing aids may not be sufficient, although they did not connect their results directly to speech production outcomes. Pratt, Grayhack, Palmer, and Sabo (2003) found that differences in hearing aid configuration could alter vowel spacing of children even though the children in their study had intelligible speech, and the speech tokens measured were limited to acceptable productions. Their data indicated that hearing aids could alter the speech of children, but provided little information about the impact that hearing aids may have on speech development. Given the paucity of data-as well as the expansion of universal infant hearing screening programs-it is critical that more research be done in this area. Increasing numbers of infants with hearing loss will be identified shortly after birth and, if we are to effectively treat them, more should be known about the impact that hearing aids and other sensory aids have on speech and auditory system development.

Early childhood poverty is a prevalent social issue, both in the United States and in the wider international community. It has been well established that factors associated with poverty, including familial income and parental education level, can negatively affect children’s language and cognitive development, which can result in academic achievement deficits that compound across the lifespan. Additional environmental factors, specifically maternal and children’s own social–emotional development, have also been shown to impact these sensitive early childhood developmental processes. Although individual components that relate to language and cognitive development in young children have been identified, additional examination of potential associative relationships between these components is warranted. Therefore, this study explored socio-economical, health, and developmental relationships between 122 caregiver–child dyads enrolled in an Early Head Start Program where children were 1–36 months old. Results indicated strong bidirectional correlations between children’s cognitive and language development. Multiple linear regression path analysis indicated that children’s cognition and social–emotional wellbeing have a significant direct effect on their language development. Additionally, language and fine motor development were found to have a significant direct effect and social–emotional wellbeing mediated an indirect effect through language on children’s cognitive development. In light of socioeconomic and sociocultural challenges, the importance of nurturing children’s social–emotional development in relation to language and cognitive development is discussed.

Literature has always been regarded as one of the best methods available that can positively influence the development of young preschool and kindergarten children, but also older school kids. However, in order for it to make a significant impact, we need to make sure that the content that is being read is appropriate for the age of the children we are reading to. If young children are exposed to adult literature or such that they cannot understand at their language level, it does not help their language improvement and development. In order for literature to make a full impact on both language and cognitive development, we need to use appropriate materials to reach satisfying results, in this case, genres which have been specifically crafted for the language level of the targeted audience. The aim of this paper was to explore the impact of reading to children (specifically literature designed for their language level) by doing a replication study based on the paper done by Fekonja et al. (2007), analyse the results and compare the two classes on a language measurement scale in order to see the impact of literature on language development. The results showed a significant difference in language development between the two groups, favouring the experimental group, which reinforces the importance of incorporating systematic reading of children’s literature into educational practices.

Moderating effects of maternal emotional availability on language and cognitive development in toddlers of mothers exposed to a natural disaster in pregnancy: The QF2011 Queensland Flood Study

We examined the associations of breastfeeding initiation and duration with language and motor skill development in a nationally representative sample of US children aged 10 to 71 months. Using cross-sectional data on 22399 children from the 2003 National Survey of Children's Health, we examined relationships between breastfeeding practices and children's language and motor skills development. Outcomes were based on each mother's response to questions regarding her level of concern (a lot, a little, not at all) about her child's development of expressive language, receptive language, fine motor skills, and gross motor skills. Breastfeeding data were based on mothers' recall. Methods of variance estimation were applied and multivariate polynomial regression modeling was done to estimate the effects of breastfeeding initiation and duration on children's development after adjustment for confounders. Mean age of the sample was 2.79 years; 67% were non-Hispanic white, 16% were Hispanic, and 9% were non-Hispanic black. Approximately 17% of mothers reported concerns about their child's expressive language development; approximately 10% had receptive language concerns; approximately 6% had concerns about fine motor skills; and 5% reported general motor skills concerns. Multivariate analysis revealed that mothers who initiated breastfeeding were less likely than mothers of never-breastfed children to be concerned a lot about their child's expressive and receptive language development and fine and general motor skills. Mothers of children breastfed 3 to 5.9 months were less likely than mothers of never-breastfed children to be concerned a lot about their child's expressive and receptive language and fine and general motor skills. As with all cross-sectional data, results should be interpreted with caution. Our findings suggest breastfeeding may protect against delays in young children's language and motor skill development. Fewer concerns about language and motor skill development were evident for children breastfed >or=3 months, and concerns generally decreased as breastfeeding continued >or=9 months.

The research described in this article uses findings from longitudinal studies involving electrophysiological and behavioral assessments of infants and young children. Event-Related Potentials (ERPs) offer a basis for understanding how areas of the brain react to specific stimuli that are thought to play a role in the development of language and reading abilities. In this paper, we review a series of studies that identify markers in the ERPs that are related to differences in the development of language and reading skills. In addition, there is compelling evidence supporting the role of the home environment and other variables that influence the intellectual level of the child’s environment (e.g., SES, parental IQ, parenting practices, family activities) in the development of language and reading in preschool and school-aged children. In this paper, measures of these environmental variables are linked with predictions of language and reading skill development. Efforts to integrate information about the influence of the environment on brain responses to better understand the development of early language and reading skills are described.

Purpose: This study focused on the parents’ language control type to young children’s behavior, and the relationship between young children’s self-help skills, language development. Methods: For this study (Parents’ Language Control Type Scale), and (Korean-Child Development Inventory) was used. This study was proceeded with 2 to 5 year-old children, each 73 of their mothers and fathers, total 219 subjects. Results: First, “position-oriented” type of parents’ language control type is shown the highest for both mothers and fathers. “Person-oriented” type, “imperative-oriented” type followed in order. Second, parents’ language control type and young children’s selfhelp skills appeared to be significant correlation. Also it appeared that for both mothers and fathers, the higher “imperative-oriented” type, the lower young children’s language expression/development level of linguistic understanding. Conclusion: The higher mothers’ “person-oriented” type, the higher young children’s language expression and development level of linguistic understanding.
