The Relations among Infant Temperament, Security of Attachment, and Behavioral Inhibition at Twenty-Four Months

The purpose of this study was to examine the relations among infant temperament, attachment, and behavioral inhibition. 52 infants were seen at 2 days, 5, 14, and 24 months of age. Assessments were made of temperament at 2 days and 5 months of age, and attachment and behavioral inhibition were assessed at 14 and 24 months, respectively. EKG was recorded at each assessment, and measures of heart period and vagal tone were computed. Distress to pacifier withdrawal at 2 days of age was related to insecure attachment at 14 months. 2 types of distress reactivity at 5 months, reactivity to frustration and reactivity to novelty, were identified and related to high vagal tone. Attachment classification at 14 months was directly related to inhibited behavior at 24 months. Infants classified as insecure/resistant were more inhibited than those classified as insecure/avoidant. In addition, an interaction of infant reactivity to frustration and attachment classification was found to predict inhibition at 24 months. Infants classified as insecure/resistant and who had not cried to the arm restraint procedure at 5 months were the most inhibited at 24 months. These findings are discussed in terms of hypotheses regarding multiple modes of distress reactivity and regulation in early infancy and their different social and behavioral outcomes.     

Conditions of Continuity and Discontinuity in Infant Negative Emotionality: Newborn to Five Months

This study investigated infant and caregiving-environment variables associated with continuity and discontinuity in infant negative emotionality between the newborn period and 5 months of age. Comparisons were made between groups of infants who evidenced similar levels of crying as neonates but differed by 5 months of age. For initially high-crying infants, mother personality traits, marital quality, and infant variables measured neonatally discriminated stable from changing infants. Ratings of mother sensitivity and infant responsiveness made at 5 months of age also related to continuity and discontinuity in negative emotionality over the first 5 months.     

Maternal Docosahexaenoic Acid Intake Levels During Pregnancy and Infant Performance on a Novel Object Search Task at 22 Months

This study investigated maternal prenatal docosahexaenoic acid (DHA) intake and infant cognitive development at 22 months. Estimates for second‐ and third‐trimester maternal DHA intake levels were obtained using a comprehensive Food Frequency Questionnaire. Infants (n = 67) were assessed at 22 months on a novel object search task. Mothers' DHA intake levels were divided into high or low groups, with analyses revealing a significant positive effect of third‐trimester DHA on object search task performance. The third trimester appears to be a critical time for ensuring adequate maternal DHA levels to facilitate optimum cognitive development in late infancy.

Infant Neurosensory Development: Considerations for Infant Child Care

Infant brain development is a dynamic process dependent upon endogenous and exogenous stimulation and a supportive environment. A critical period of brain and neurosensory development occurs during the third trimester and into the “fourth” trimester (first three months of life). Disruption, damage, or deprivation in the infant’s social and physical environment can create permanent deficits in the developing neurosensory systems. Implications for infant child care environments are discussed, and a review of quality and standards in infant child care environments leads to a call for improvements to optimize child development.     

Attention to Faces Expressing Negative Emotion at 7 Months Predicts Attachment Security at 14 Months

To investigate potential infant‐related antecedents characterizing later attachment security, this study tested whether attention to facial expressions, assessed with an eye‐tracking paradigm at 7 months of age (N = 73), predicted infant–mother attachment in the Strange Situation Procedure at 14 months. Attention to fearful faces at 7 months predicted attachment security, with a smaller attentional bias to fearful expressions associated with insecure attachment. Attachment disorganization in particular was linked to an absence of the age‐typical attentional bias to fear. These data provide the first evidence linking infants' attentional bias to negative facial expressions with attachment formation and suggest reduced sensitivity to facial expressions of negative emotion as a testable trait that could link attachment disorganization with later behavioral outcomes.     

Beyond Rough and Tumble: Low-Income Fathers' Interactions and Children's Cognitive Development at 24 Months

Objective. The purpose of this investigation was to explore associations between father-child interactions and children's cognitive status in an underrepresented group of low-income, ethnically diverse families. Design. Participants were 65 inner-city fathers and their 24-month-old children (34 boys, 31 girls). Father-child interactions were videotaped for 10 min at home during semistructured free play, and mental scale scores on the Bayley Scales of Infant Development were obtained on children. The quality of father-child interactions was assessed using 14 Likert ratings of fathers (e.g., responsiveness, language quality, and intrusiveness) and 12 of children (e.g., play, participation, emotional regulation, and communication). Results. Factor analyses revealed 2 patterns of engagement in fathers (Responsive-Didactic and Negative-Intrusive) and 3 in children (Playful-Communicative, Social, and Regulated). Thirty-six children scored within normal limits on the MDI and 29 scored in the delayed range. Together, fathers' and children's factor scores explained more than 25% of the variance in children's performance on the MDI. Logistic regressions indicated that fathers with high scores on the Responsive-Didactic factor were nearly 5 times more likely to have children within the normal range on the MDI than were low-scoring fathers. Conclusions. These findings point to the importance of considering fathers' role in early cognitive development, particularly in low-income families in which children begin to exhibit significant declines in their second and third years. Positive father-child interactions appear to obviate cognitive delay.     

Infant attention scaffolding at home

The purpose of the study was to identify the mechanisms underlying the links between maternal attention directing strategies and infants’ focused attention. In the first year of life temporal organisation of dyadic behaviour was examined in the home. A sample of 50 dyads was videorecorded for one hour during usual activities, twice at 5- and 8-months of age. Onset and offset of maternal behaviours toward objects, and infants’ attention were noted. Sequential analyses demonstrated dependencies between partner’s behaviours: infants and mothers adjusted to each other’s activity. Maternal behaviours were classified as introducing, maintaining and redirecting attention: over both ages, the most frequent maternal behaviour was introducing, which did not systematically attract the infant’s attention; maintaining was the second most frequent maternal behaviour. Infants focused their attention longer when the mother used introducing or maintaining strategies. Older infants initiated a greater proportion of attention focusing episodes. At both ages inter-dyads variability is very large, with a significant inter-ages stability. The present data bring further support to the interpretation of parental activity as a genuine scaffolding of attention.     

Contextual Constraints on Memory Retrieval at Six Months

In 3 experiments, 6-month-old infants learned to move a mobile by kicking and were tested 1 to 21 days later for retention of the newly acquired memory as a function of the training and testing contexts. In Experiment 1, decreasing the relative distinctiveness of the training and testing context did not impair retrieval of the newly acquired memory. In Experiment 2, however, testing in a different context completely eliminated retention after delays of 1 and 3 days, when retention was otherwise perfect; after progressively longer delays, retention improved paradoxically. The familiarity or novelty of the test context was not a factor in the failure of infants to recognize the mobile in the altered context after 1 day. In Experiment 3, the effect of an altered context was assessed in a reactivation paradigm. After the training memory was forgotten, infants were presented with the original mobile as a reminder and were tested for retention of the training memory 1 day later. When either the reminding context or the testing context was different, they exhibited no retention. These findings reveal that memory retrieval at 6 months is highly specific to the setting in which the memory is acquired. We propose that infants learn what specific events are associated with what specific places prior to the age when they can locomote independently and acquire a spatiotemporal map of the relations between those places.     

Contextual Variation and Memory Retrieval at Six Months

In 2 experiments we asked whether training in multiple contexts could eliminate context-dependent memory retrieval at 6 months as it does for adults. We found that 24-hour retention was disrupted when infants were trained in one context and tested in another but not when they were trained in multiple contexts prior to testing in a novel context (Experiment 1). After a long delay, however, training in multiple contexts did not facilitate memory retrieval in a novel context: An otherwise effective retrieval cue (the training mobile) did not alleviate forgetting 3 weeks later when it was presented in a novel context (Experiment 2). These findings demonstrate that multiple learning contexts can override the debilitating effects of an altered context on memory retrieval at 6 months, but only over the short term. The resistance of older memories to retrieval in novel contexts after long periods of disuse may be adaptive, insuring that potentially inappropriate or irrelevant memories will not be expressed.     

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.     

Long-Term Memory for Context-Specific Category Information at Six Months

The ability of 6-month-old infants to remember a functional category acquired in a specific context was assessed in 3 experiments via an operant procedure in which infants learned to perform a specific action (a footkick) to activate an object suspended before them. In Experiment 1, infants trained with different exemplars in the same context transferred responding to a novel exemplar in the same but not a different context 24 hours later. Experiment 2 revealed that infants' reactivated memory of category training remained intact and context-specific after 3 weeks. In Experiment 3, a novel category exemplar was able to reactivate the forgotten memory of category training only in the encoding context. At 6 months, information about the place where categories are constructed is prerequisite for retrieval of a category concept from long-term memory. This requirement insures that early category concepts remain stable over relatively long periods.

Superior Detection of Faces in Male Infants at 2 Months

Females generally attend more to social information than males; however, little is known about the early development of these sex differences. With eye tracking, 2-month olds’ (N = 101; 44 females) social orienting to faces was measured within four-item image arrays. Infants were more likely to detect human faces compared to objects, suggesting a functional face detection system. Unexpectedly, males looked longer at human faces than females, and only males looked faster and longer at human faces compared to objects. Females, in contrast, looked less at human faces relative to animal faces and objects, appearing socially disinterested. Notably, this is the first report of a male face detection advantage at any age. These findings suggest a unique stage in early infant social development.

Disorganized Infant Attachment Classification and Maternal Psychosocial Problems as Predictors of Hostile-Aggressive Behavior in the Preschool Classroom

This study of 62 lowincome families examined the relation between maternal and infant measures assessed at 18 months infant age and child behavior problems at age 5 as rated by preschool teachers. The infancy assessments included measures of mother-infant interaction, maternal psychosocial problems, infant cognitive development, and infant attachment security, including the disorganized/disoriented classification. The strongest single predictor of deviant levels of hostile behavior toward peers in the classroom was earlier disorganized/disoriented attachment status, with 71% of hostile preschoolers classified as disorganized in their attachment relationships in infancy. Maternal psychosocial problems independently predicted hostile aggressions in preschool and combined additively with infant attachment security in prediction. Results are discussed in relation to the asymmetry of forward and backward prediction that characterized the findings and in relation to the potential significance of disorganized attachment behavior as a precursor to later maladaptation.     

秦二世十二岁即位说

秦二世即位之年龄,学界多谓二十一岁,然考之史实则似不符。《史记》引《秦记》原作十二岁即位;少子即幼子说不易推倒;胡亥缺乏起码的政治和生活常识,是非不分,甚至难辨鹿马;胡亥无淫乱记载,也未曾留下后代;胡亥童趣未泯,思路幼稚。诸多迹象表明,秦二世十二岁即位说应可成立。
