Naturalistic Language Recordings Reveal “Hypervocal” Infants at High Familial Risk for Autism

Children's early language environments are related to later development. Little is known about this association in siblings of children with autism spectrum disorder (ASD), who often experience language delays or have ASD. Fifty‐nine 9‐month‐old infants at high or low familial risk for ASD contributed full‐day in‐home language recordings. High‐risk infants produced more vocalizations than low‐risk peers; conversational turns and adult words did not differ by group. Vocalization differences were driven by a subgroup of “hypervocal” infants. Despite more vocalizations overall, these infants engaged in less social babbling during a standardized clinic assessment, and they experienced fewer conversational turns relative to their rate of vocalizations. Two ways in which these individual and environmental differences may relate to subsequent development are discussed.     

Intuitive parenting as a model for understanding parent-infant interactions when one partner is deaf.

This paper reviews the concept of intuitive parenting, with particular focus on its applicability to parent-infant dyads in which the parent or child is deaf. Although the conceptual model discussed in this paper was developed primarily from observations of hearing dyads, it has the potential to contribute to our understanding of early adaptive processes in other populations as well. Examples of nonconscious or intuitive parental behaviors are presented in terms of the ways they help infants adapt to the postnatal environment and in the later transition from preverbal to verbal stages of development. In addition, implications are drawn for difficulties in parent-infant interactions that may occur as a result of deafness in the parent or child.     

Early Intervention with Medically Fragile Infants: Investigating the Age-at-Start Question

Very few studies have investigated the age at which early intervention should begin. Similarly few studies have examined the effects of early intervention for infants who are medically fragile. The present study responds to these two critical issues by longitudinally comparing groups of infants who are medically fragile. These infants were randomly assigned to receive developmentally appropriate programs beginning at either 3- or 18-months adjusted age. Analysis of measures of child development and family functioning for the first three annual assessments indicated that the two groups were similar on measures of child functioning at the first and second assessment. However, at the third assessment, children who received the intervention at an earlier age scored significantly higher than did children whose intervention began 15 months later. No significant group differences were found on measures of family functioning at any of the assessments. Implications of these results for future research and practice are discussed.

The Media and Creativity

Sooner or later, all educational techniques are examined from the point of view of creativity. The concept of creativity is difficult to define and in the same way the examination, too, runs the risk of being too vague. With regard to the media, it is possible to perform a more modest examination of the situation of the receiver, according to the indices of his passivity or his activity.     

The relationship between affective and cognitive development in Down's Syndrome infants.

A close association between affective expression and cognitive development was demonstrated in a longitudinal study of 14 Down's syndrome infants. It was found that the Down's syndrome infants laughed to groups of stimulus items in the same order as did previous samples of normal infants. Although the process was delayed by several months, the retarded babies too laughed first at physically intrusive items and only later to items calling for greater cognitive sophistication. In addition, cognitive developmental status, assessed by the Bayley and Uzgiris-Hunt scales, paralleled and was predicted by the level of affective development. Predictive and concurrent correlations between Bayley mental scores and various indices of affectivity ranged from .68 to .92. There was striking individual consistency across affective, mental, and motor measures, suggesting the organized nature of retarded development. Finally, since Down's syndrome infants frequently smiled under conditions when normal babies would laugh, a role for tension production, in addition to cognitive factors, was suggested in accounting for the behavior of these infants.     

Cost Effective Approaches to Identifying Developmental Delay in 4- to 7-Year-Old Children

Recent enactment of public laws have mandated early identification of children at risk for delayed development. Several complex assessment batteries have demonstrated satisfactory predictive and classificatory accuracy when biomedical and social-environmental measures obtained in infancy are used as predictors of later IQ scores. Yet, these complex batteries are too costly for wide- spread adoption. The present study examined the effectiveness of smaller sets of predictor variables for correctly identifying children as developmentally delayed at four through seven years of age. The results show that a combination of six biomedical risk items, maternal education level, and four subscale scores from the HOME scale are effective when used as a screening battery across a four year period. The practical implications are for this battery to be used to screen children in the preschool period for developmental delay in the early primary grades.

Attachment classification from the perspective of infant-caregiver relationships and infant temperament

Recently a number of investigators have suggested that classification differences in the Ainsworth Strange Situation (anxious and secure patterns of attachment) may be due largely or in part to endogenous temperamental variation. In doing so, these investigators have suggested a dimensional-trait approach in place of a qualitatively different taxonomic approach. Moreover, much evidence is directly contrary to a strong temperament interpretation of attachment patterns (changing attachments, differing attachments with different caregivers, prospective data on the early characteristics of infants later classified as securely or anxiously attached). Other interactionist temperament models currently have not been tested sufficiently. At the same time, a host of research findings support the interpretation that Ainsworth assessments capture aspects of the relationship between infant and caregiver, as derived from the history of their interaction. This includes direct evidence from observations of infants and mothers over time, the influence of varying patterns of care within and between cultures, the impact of factors presumed to influence quality of care (e.g., social support, life stress, caregiver family history), and predictions of later parent behavior from strange situation assessments of infant behavior. The importance of understanding attachment as a relational concept is twofold: it represents a theoretical and paradigmatic shift of importance for many aspects of developmental psychology, and it opens the way for more productive research on temperament, the interaction between temperament and experience, and important process studies of the unfolding of the infant-caregiver relationship.     

Individual differences in habituation rates and object concept performance.

The scores from object concept tasks for 15 infants at 14 months of age were analyzed with respect to their habituation rates at 4 months of age. Partitioning of the data according to subjects categorized as fast and slow habituators brought some organization consistent with the notion that the former are more advanced than the latter. Statistical differences between groups did not obtain, but a significant correlation between ranked task scores and habituation ratios offers some support to the interpretation. The possibility of using habituation rates or ratios as an index of differences in processing, perhaps with some predictive value, may be considered if further evidence of relations to later cognitive performanceis found.     

Limited Fine Motor and Grasping Skills in 6‐Month‐Old Infants at High Risk for Autism

Atypical motor behaviors are common among children with autism spectrum disorders (ASD). However, little is known about onset and functional implications of differences in early motor development among infants later diagnosed with ASD. Two prospective experiments were conducted to investigate motor skills among 6‐month‐olds at increased risk (high risk) for ASD (N₁ = 129; N₂ = 46). Infants were assessed using the Mullen Scales of Early Learning (MSEL) and during toy play. Across both experiments, high‐risk infants exhibited less mature object manipulation in a highly structured (MSEL) context and reduced grasping activity in an unstructured (free‐play) context than infants with no family history of ASD. Longitudinal assessments suggest that between 6 and 10 months, grasping activity increases in high‐risk infants.     

Early Home Environment and Mental Test Performance: A Structural Analysis

A theoretical model of early environment action was examined on a sample of 282 infants representing two racial groups (Caucasian, African-American). Children were obtained from three different sites in the United States. The model examined included the following variables: socioeconomic status (SES), early cognitive status (Bayley MDI at 12 months), stimulation within the home environment (subscales from the HOME Inventory at 12 and 24 months), parents use of negative control (subscales from the HOME Inventory at 12 and 24 months), and later cognitive status (36-month Stanford-Binet IQ). Structural Equation Modeling (SEM) with the LISREL software was used to confirm the fit of the model for African-Americans and Caucasians and for males and females separately. The models for males and females had similar structures, but not equal coefficients for all paths in the model. The models showed significant paths from socioeconomic status and early cognitive status to stimulation with the home environment, a significant path from SES to negative parental control, and a significant path from stimulation within the home environment to later cognitive status. The models for African-Americans and Caucasians differed in structure. For African-Americans, there was no evidence that the link between SES and 36-month IQ was mediated through negative control but SES and early cognitive status were linked to later IQ via the amount of stimulation provided in the home. For Caucasians, early cognitive status did not appear related to 36- month IQ but negative control did appear to mediate the relation between SES and IQ.     

Siblings as models in early infant learning

4 groups of infants, 2 at 6 months and 2 at 12 months, were tested on the Stage IV-V and V-VI object concept tasks. All groups were then retested on the same tasks 1 week later. Retesting of the experimental groups was preceded by an all-correct demonstration of the 2 search tasks by the infant's preschool sibling; control groups were not exposed to any model prior to reassessment. No effect of exposure to the sibling model was initially found in either age group. If, however, infants' initial stage of development was taken into account, cognitive performance on the lower-level task did show a significant improvement after modeling. Overall, the results suggest that sibling modeling could possibly be an effective method of facilitating cognitive development in infancy, but that the success or failure of any modeling attempt may be stage- rather than age-dependent.

Long-term hospitalization of failure-to-thrive infants: Developmental outcome at three years

The present study documented later developmental outcome in a group of 29 failure-to-thrive (FTT) infants who received extended hospitalization in infancy as an intervention for their growth failure. All infants were seen at approximately 3 years of age and were given standardized assessments of intellectual and physical development. A standard interview documented demographic variables, health problems, placements subsequent to hospitalization and additional psychological and medical treatment. Infants were divided into three groups dependent on medical and treatment factors. Means and percentages of occurrence of outcome variables were compared through either one-way ANOVAS or single sample chi-square tests with post hoc analyses. Correlational analyses were used to understand the relationships between outcome and relevant demographic, medical, and treatment variables. In general, the infants manifest persistent intellectual delays at follow-up despite maintenance of weight gains achieved during early hospitalization. More than half the group suffered from chronic health problems. A large percentage of infants had been removed from parental custody at the time of follow-up. Several demographic, medical, and treatment factors bore moderate relationships to developmental outcome. Infants who achieved more optimal growth tended to be full-term at birth, later born and without a question of physical abuse in their social histories. Intellectual functioning was related only to parental and caretaker socioeconomic status. Infants placed in foster care were unlikely to return to their families of origin. The findings suggest the need for further investigation into the determinants and outcome of extended hospitalization as a treatment for FTT.     

学前儿童家教中情商培养的误区及应对策略

家庭教育是学前儿童情商培养的重要途径,但是注重智力开发、轻视情商培养的现象普遍存在。家长往往缺少平等意识、责任意识和榜样意识,教育观念偏颇,教育方法简单。主要表现有五种：母鸡式教育,放羊式教育,金丝雀式教育,棍棒式教育,挡箭牌式教育。应对策略是思想重视,有意培养;文明礼貌,鼓励交往;互助友爱,学会分享;正视挫折,自立自强。可运用游戏教育法、榜样示范法、激励评价法、心理暗示法等因材施教。     

A Meta-Analysis of Infant Habituation and Recognition Memory Performance as Predictors of Later IQ

A meta-analytic review of the literature on infant habituation and recognition memory performance as predictors of later IQ suggests several conclusions: (1) Habituation and recognition memory assessments made on a variety of risk and nonrisk samples in the first year of life predict later IQ assessed between 1 and 8 years of age with a weighted (for N ) average of normalized correlations of .36 or a raw median correlation of .45. (2) The size of the predictive correlation is essentially the same for habituation and for recognition memory paradigms. (3) This prediction phenomenon is not obviously associated solely with one laboratory, one particular infant response measure, or a few extremely disordered infants. (4) The level of prediction to childhood IQ is substantial given the reliability of the infant measures. (5) Predictions are somewhat higher for risk than for nonrisk samples. (6) Predictions are consistently higher than for standardized infant tests of general development for nonrisk but not for risk samples, and they are not consistently higher than predicting from parental education and socioeconomic status or a few other infant behaviors for nonrisk samples. (8) Coefficients may be higher when the predicting assessments are made between 2 and 8 months of age than earlier or later, but prediction coefficients are remarkably consistent across the observed outcome age period of 2–8 years.     

Behavioral Regulatory Problems Are Associated With a Lower Attentional Bias to Fearful Faces During Infancy

To investigate the role of early regulatory problems (RP), such as problems in feeding, sleeping, and calming down during later development, the association between parent-reported RP at 3 months (no-RP, n = 110; RP, n = 66) and attention to emotional faces at 8 months was studied. Eight-month-old infants had a strong tendency to look at faces and to specifically fearful faces, and the individual variance in this tendency was assessed with eye tracking using a face-distractor paradigm. The early RPs were related to a lower attention bias to fearful faces compared to happy and neutral faces after controlling for temperamental negative affectivity. This suggests that early RPs are related to the processing of emotional information later during infancy.
