How bilingual experience and executive control influence development in language control among bilingual children

This longitudinal study investigates whether the development in executive control and bilingual experience predicts change in language control in bilingual children. Children were tested twice over the course of 1 year, using the language‐switching paradigm and the Simon task. The participants were Japanese‐English bilingual “returnee” children (ages 7–13), who returned to their first language (L1) environment after spending some years in a second language (L2) dominant environment. Testing these children upon their return to the L1 environment allowed us to disentangle the effect of age from bilingual experience, as they experienced an increase in age but a decrease in L2 exposure over time. Children who had less L2 exposure showed smaller improvement in baseline performance when naming pictures in English (i.e., when English was relevant across all trials). Moreover, development in trials where children had to switch between languages were modulated by development in executive control. That is, children who increased their performance in the English mixed repetition trials also performed better on the executive control task over time. Thus, development in executive control modulated change in language control among bilingual children, suggesting a positive relationship between language control and executive control in children's development.     

Developmental changes associated with cross-language similarity in bilingual children

The main goal of the present study was to investigate how the degree of orthographic overlap between translation equivalents influences bilingual word recognition processes at different stages of reading development. Spanish–Basque bilingual children with ages ranging from 8 to 15 years were tested in an explicit translation recognition task with a large set of items. Critically, the degree of cross-language similarity (i.e. the cognate status) between the references and the correct targets was manipulated along a continuum in order to investigate how the reliance on cross-language orthographic overlap varies as a function of reading experience. Results showed that younger children were significantly more sensitive to the cognate status of words than older children while recognising translation equivalents, and that this difference did not depend on the speed of response of the participants. These results demonstrate that the influence of cross-language similarity progressively diminishes as a function of increased exposure to print together with the maturation of the mechanisms responsible for language interference suppression, as suggested by developmental models of bilingual lexical access.     

Developmental trajectories and reciprocal associations between career adaptability and vocational identity: A three-wave longitudinal study with adolescents

The purpose of this longitudinal study was two-fold. First, we investigated patterns of stability and change in career adaptability and vocational identity in adolescents. Second, we examined reciprocal associations between career adaptability and vocational identity. In addressing both research aims we tested the moderating effects of gender, school-type, and age. Participants were 1151 (58.7% female) adolescents. They filled in measures that appraised career adapt-abilities and vocational identity processes three times during a school year. Latent growth curve analyses highlighted slight longitudinal decreases in career concern, control, and confidence especially in boys, vocational school students, and middle-to-late adolescents. Also, over time boys and students attending vocational schools reported less in-depth occupational exploration, less identification with present vocational commitments, and more flexibility and self-doubt about their careers. Findings of cross-lagged path analyses highlighted reciprocal associations between career adaptability and vocational identity. Career adaptability positively predicted adolescents' ways of dealing with vocational exploration and commitment. Vocational commitment and reconsideration of commitment predicted career adapt-abilities in time. These results indicate that career adaptability and vocational identity are dynamic and interrelated dimensions of adolescent career development. Implications for theory and practice are discussed.     

Attentional control in early and later bilingual children

We examined differences in attentional control among school-age children who were monolingual English speakers, early Spanish-English bilinguals (who began speaking both languages by age 3), and later Spanish-English bilingual children (who began speaking English after age 3). Children's attentional control was tested using the Attention Network Test (ANT). All language groups performed equally on ANT networks; however, when controlling for age and verbal ability, groups differed significantly on reaction time. Early bilingual children responded faster on the ANT compared to both monolingual and later bilingual children, suggesting an attentional monitoring advantage for early bilinguals. These results add to evidence of advantaged cognitive functioning among bilinguals and are consistent with the possibility that children who begin speaking a second language earlier in childhood have greater advantages, due either to effects of acquiring a second language earlier or to longer duration of bilingual experience.     

Developmental changes in associations between auditory-visual events

The goal of the present study was twofold: to examine the influence of two amodal properties, co-location and temporal synchrony, on infants' associating a sight with a sound, and to determine if the relative influence of these properties on crossmodal learning changes with age. During familiarization 2-, 4-, 6- and 8-month-olds were presented two toys and a sound, with sights and sounds varying with respect to co-location and temporal synchrony. Following each familiarization phase infants were given a paired preference test to assess their learning of sight-sound associations. Measures of preferential looking revealed age-related changes in the influence of co-location and temporal synchrony on infants' learning sight-sound associations. At all ages, infants could use temporal synchrony and co-location as a basis for associating an auditory with a visual event and, in the absence of temporal synchrony, co-location was sufficient to support crossmodal learning. However, when these cues conflicted there were developmental changes in the influence of these cues on infants' learning auditory-visual associations. At 2 and 4 months infants associated the sounds with the toy that moved in synchrony with the sound's rhythm despite extreme violation of co-location of this sight and sound. In contrast, 6- and 8-month-olds did not associate a specific toy with the sound when co-location and synchrony information conflicted. The findings highlight the unique and interactive effects of distinct amodal properties on infants' learning arbitrary crossmodal relations. Possible explanations for the age shift in performance are discussed.     

Developmental changes in the relations between inhibitory control and externalizing problems during early childhood

Deficits in executive function, and in particular, reduced capacity to inhibit a dominant action, are a risk factor for externalizing problems (EP). Inhibitory control (IC) develops in the later preschool and early childhood periods, such that IC might not regulate EP in toddlers and younger preschoolers. Aggression was observed during peer play for 66 girls and 49 boys, from 2.75 to 6.00 years (M=4.14, S.D.=0.78). Mothers reported on children's IC and EP concurrently and 12 months later, and concurrent teacher reports of EP were also collected. Factor analysis supported aggregation of mother and teacher‐reported EP and observed physical aggression into one measure of externalizing difficulties. Mothers reported lower IC for children with more externalizing difficulties, and the inverse relation between IC and externalizing difficulties strengthened over the toddler, preschool and kindergarten periods. Similar relations between IC and EP were observed 12 months later, and increases in IC also predicted reductions in EP over 1 year. These data demonstrate that the preschool years are a dynamic period of developmental change in the relations between IC and EP. Copyright © 2010 John Wiley & Sons, Ltd.     

Showing and telling about emotions: Interrelations between facets of emotional competence and associations with classroom adjustment in Head Start preschoolers

In this study of low income preschoolers (N?=? 60), we examined relations between three facets of emotional competence: emotion knowledge, level of negative emotion expression, and emotion regulation; and their associations with indicators of classroom adjustment. Emotion knowledge was positively related to positive emotion regulation but was not related to negative emotion expression or negative dysregulation. Negative emotion expression related to emotion regulation variables in expected directions. Negative emotion expression was associated with aggression and social skills after covarying verbal ability, age, and emotion knowledge. Negative dysregulation was related in expected directions to aggression, anxiety, and social skills after covarying verbal ability, age, emotion knowledge, and negative emotion expression. Positive emotion regulation was related negatively to anxiety and positively to social skills after covarying all other variables in the model. Results are discussed with regard to using the emotional competence domain to understand how emotion processing relates to early childhood adjustment.     

Formation of excitatory and inhibitory associations between absent events

Considerable evidence indicates that associations may be formed between two events even when one or both of them is absent at the time of learning. Previously, some researchers asserted that excitatory associations are formed when associatively activated representations for two events are paired, whereas others claimed that inhibitory associations are formed. In three experiments, the authors investigated the nature of tone-sucrose learning when associatively activated representations of those events were paired in the absence of either of the events themselves. Experiment 1 found substantial excitatory learning when the tone surrogate preceded the sucrose surrogate in training. Experiment 2 evaluated other accounts for the results of Experiment 1, and Experiment 3 found evidence for inhibitory tone-sucrose learning when the tone and sucrose surrogates were presented in simultaneous or backward order. The results indicated that the nature of representation-mediated learning is influenced by some of the same variables as more standard associative learning.     

Friendship and social competence in a sample of preschool children attending Head Start

Relations between friendship (operationalized as reciprocated or nonreciprocated sociometric choices) and social competence were studied for children (mostly African American) attending Head Start. Initial analyses showed that children with reciprocated friends had higher social competence scores than children without reciprocated friends. Correlations suggested that the number of reciprocated friendships was associated with the social competence indicators studied here. Beyond the cost of having no reciprocated friends, having nonreciprocated friendships was not a liability. Cross-time analyses suggested differing patterns of relations for boys and girls. Having versus not having a reciprocated friend was unstable across time, because there was a trend toward participating in reciprocated friendships from 3 to 4 years of age (most older children had at least 1 reciprocated friend). For girls there was a positive relation between the number of reciprocated friendships at Time 1 and at Time 2. No benefit (in terms of social competence) was found for children making the transition from 1 classroom to the next with a friend.     

School readiness in children living in non-parental care: Impacts of Head Start

The current study examines the effects of Head Start on the development of school readiness outcomes for children living in non-parental care. Data were obtained from the Head Start Impact Study, a randomized controlled trial of Head Start conducted with a nationally representative sample of Head Start programs and families. The sample included 253 children living in non-parental care (defined as a primary caregiver who self-identified as someone other than a biological, adoptive, or step-parent), who experienced elevated rates of child and family risk factors. Results revealed modest direct short-term and indirect longer-term impacts of Head Start on school readiness outcomes (increased pre-academic skills, more positive teacher–child relationships, and reductions in behavior problems) for children living in non-parental care. Limitations of this study and directions for future research are discussed.     

Teaching oddity and insertion to Head Start children: An economical cognitive intervention

Two interventions were offered to Head Start preschoolers. Half of the children played numerous learning set games designed to teach the children (1) the oddity principle and (2) how to insert objects into a series. Mastery of these concepts is theoretically an important aspect of school readiness. The other half of the children engaged in the I Can Problem Solve (ICPS) exercises, a program designed to increase the children's competency in recognizing and responding to other people's feelings. The children who played the learning set games became superior at oddity and insertions with manipulable objects, and generalized these games to workbook-like formats resembling those encountered in kindergarten. They also scored higher on the numeracy and memory scales of the McCarthy Scales of Children's Abilities, indicating that mastery of oddity and insertions may have served as foundations for further cognitive growth. The children who participated in the ICPS exercises became superior at creating solutions to interpersonal problems, as measured by the Preschoolers Interpersonal Problem Solving Scale. The differences in the outcomes indicate that both interventions were successful in their own domains. The advantage the cognitive intervention produced on the McCarthy Scales suggests that oddity and insertion abilities may be a foundation in fact as well as in theory for general cognitive growth at this age.     

Developmental trajectories of teacher-student relationships and longitudinal associations with children's conduct problems from Grades 1 to 12

This study examined the development and continuity of teacher-student relationship quality across the formal schooling years (Grades 1 to 12) and investigated how variations (i.e., differential trajectories) in teacher-student relationship quality were longitudinally associated with children's conduct problems across childhood and adolescence. Participants consisted of 784 students (M_age = 6.57 in Grade 1; 47% girls, 37.4% Latino or Hispanic, 34.1% European American, and 23.2% African American) who were identified as being academically at risk (i.e., had low literacy scores at school entry). Distinct subgroups of children were identified based on variations in their teacher-student warmth and conflict trajectories, and patterns of continuity and change were also assessed across the transition to middle school. The findings provided insights into how the duration, magnitude, and timing of teacher-student relationship quality were associated with children's conduct problems. More specifically, relationships characterized by early-onset deficits, chronic and persistent relationship difficulties, or adolescent-onset conflict were associated with distinct patterns of conduct problems throughout childhood and adolescence.     

Teachers' dispositional mindfulness and the quality of their relationships with children in Head Start classrooms

The quality of teachers' relationships with children is a key predictor of children's later social emotional competence and academic achievement. Interventions to increase mindfulness among teachers have focused primarily on the impacts on teachers' subjective well-being, but not on the quality of their relationships with children. Furthermore, none of these interventions have involved preschool teachers. To consider the potential of mindfulness-based interventions to improve the quality of teachers' relationships with preschool-aged children, we examined data from an online survey of 1001 classroom teachers in 37 Pennsylvania Head Start Programs. Using path analysis we investigated the association between teachers' dispositional mindfulness and the quality of their relationships with children (conflict and closeness). We further examined whether this association was mediated by teacher depressive symptoms and moderated by perceived workplace stress. Higher levels of dispositional mindfulness among teachers were associated with higher quality relationships with children (less conflict and greater closeness). The association between greater dispositional mindfulness and less conflict was partially mediated by lower depressive symptoms, and the conditional direct effect of mindfulness on conflict was stronger when perceived workplace stress was lower. These findings suggest that preschool teachers who have higher levels of dispositional mindfulness may experience higher quality relationships with children in their classrooms. Interventions to increase levels of dispositional mindfulness among early childhood educators may improve their well-being along with the quality of their relationships with children, potentially impacting children's educational outcomes. The potential impacts of such interventions may be even stronger if structural and systemic changes are also made to reduce workplace stress.     

Switching requirements in a Head Start classroom

Two experiments were conducted by the mothers of the children in a Head Start classroom. Both examined the effects of a switching task on the frequency with which children moved from one activity area of the classroom to another. The results indicated that the rate at which the children changed activities could be adjusted by varying the difficulty or magnitude of the switching task and that the task itself could be used to introduce academic subjects which would be poorly attended if initially presented in an activity area.
