Cognitive controls: A test of their modifiability and structural arrangement

This study focused on two concepts basic to the cognitive control approach—the modifiability of cognitive control structures, and their proposed hierarchical, structural arrangement. Eighty children designated as deficient in cognitive functioning beginning at either two levels of deficiency (field articulation or leveling-sharpening) were provided one of four types of intervention. The hypotheses tested were: (a) that intervention provided directly at the level of the first deficiency would be significantly more effective than either intervention provided a level below or a level above the area of first deficiency, or of a control condition; and (b) that cognitive control structures form a hierarchical, structural arrangement. Training effects were indexed by cognitive performance measures at both pretest and pos est. The results were consistent with the initial hypothesis that cognitive control deficiencies can be remediated beer by structure-based types of intervention than by the types of skill training normally provided in the classroom. In contrast, the second hypothesis—that cognitive controls form a hierarchical, structural arrangement—was only partially confirmed. Additional systematic research into the modifiability and structural arrangement of cognitive controls was strongly recommended.     

Decreased Self-Reported Cognitive Failures after Memory Training

In recent years, attention has been focused on investigating the effectiveness of composite memory intervention programs with different age and diagnostics groups. The goal of this study was to measure changes in cognitive lapses by Cognitive Failure Questionnaire (CFQ) in a large trained, dementia free group (Mini-Mental State Examination [MMSE] > 26). The CFQ was administrated to older adults before training (Wave 1), after training (Wave 2), and in a six-month follow-up (Wave 3) to an experimental (N = 77; memory training) and control sample (N = 78, no intervention). Significant changes in subjective cognitive functioning in the experimental group and a plateau curve in the control group were observed. The results indicate support for the efficiency of a large memory-training group in promoting subjective cognitive functioning.     

Fine Motor Control is Related to Cognitive Control in Adolescents with Down Syndrome

The connection between human cognitive development and motor functioning has been systematically examined in many typical and atypical populations; however, only a few studies focus on people with Down syndrome (DS). Twelve adolescents with DS participated and their cognitive control, measured by the Corsi-Block tapping test (e.g., visual working memory), the Auditory Memory span test (e.g., verbal working memory) and the Tower of London test (e.g., cognitive planning), and motor control, measured by the Purdue Pegboard (e.g., fine motor control), were measured in this study. Results indicate that if people with DS have better performance in fine manual dexterity, they will have better performance in cognitive planning and verbal working memory abilities. The co-activation hypothesis of the prefrontal area and the cerebellum may support this positive relationship. Hence, it is suggested people with DS will obtain benefits in cognitive control by participating in further motor intervention.     

A randomized controlled trial of a home-visiting intervention aimed at preventing relationship problems in depressed mothers and their infants

This study examined the effect of a mother–baby intervention on the quality of mother–child interaction, infant–mother attachment security, and infant socioemotional functioning in a group of depressed mothers with infants aged 1–12 months. A randomized controlled trial compared an experimental group ( n = 35) receiving the intervention (8–10 home visits) with a control group ( n = 36) receiving parenting support by telephone. There were assessments pre, post, and follow-up after 6 months. The intervention had positive effects on the quality of mother–infant interaction. Infants in the experimental group had higher scores for attachment security and for one aspect of socioemotional functioning, namely, competence. The intervention proved successful in preventing deterioration of the quality of mother–child interaction.     

Effects of childhood trauma exposure and cortisol levels on cognitive functioning among breast cancer survivors

Cognitive functioning difficultiesin breast cancer patients receiving chemotherapy are common, but not all women experience these impairments. Exposure to childhood trauma may impair cognitive functioning following chemotherapy, and these impairments may be mediated by dysregulation of hypothalamic-pituitary-adrenal (HPA) axis function and cortisol slope. This study evaluated the association between childhood trauma exposure, cortisol, and cognition in a sample of breast cancer survivors. 56 women completed measures of trauma exposure (the Traumatic Events Survey), salivary cortisol, and self-reported cognitive functioning (the Functional Assessment of Cancer Therapy – Cognitive). We examined correlations between childhood trauma exposure and cognitive functioning, then used linear regression to control for factors associated with cognition (age, education, time since chemotherapy, depression, anxiety, and insomnia), and the MacArthur approach to test whether cortisol levels mediated the relationship between trauma and cognitive functioning. 57.1% of the sample had experienced at least one traumatic event in childhood, with 19.6% of the sample witnessing a serious injury, 17.9% experiencing physical abuse, and 14.3% experiencing sexual abuse. Childhood trauma exposure and cognitive functioning were moderately associated (r = −0.29). This association remained even when controlling for other factors associated with cognition; the final model explained 47% of the variance in cognitive functioning. The association between childhood trauma and cognitive functioning was mediated by steeper cortisol slope (partial r = 0.35, p = 0.02). Childhood trauma exposure is associated with self-reported cognitive functioning among breast cancer survivors and is mediated by cortisol dysregulation. Trauma should be considered, among other factors, in programs aiming to address cognition in this population.     

Parental family stress during pregnancy and cognitive functioning in early childhood: The Generation R Study

We investigated whether parental family stress during pregnancy is associated with cognitive functioning in early childhood in a population-based cohort (n = 3139). Family stress was assessed using the Family Assessment Device at the 20th week of pregnancy and was reported by mothers and fathers. Mothers completed the MacArthur Communicative Development Inventory, measuring children's verbal cognitive functioning, when children were 18 months and they completed the Parent Report of Children's Abilities, measuring nonverbal cognitive functioning, when children were 2 years old. Maternal prenatal family stress was related to children's low word comprehension and poorer nonverbal cognitive development independent of paternal reports. In a subset of 639 children, maternal prenatal family stress was also associated with observational assessments of poor effortful control at age 37 months. Paternal prenatal family stress was only related to poorer nonverbal cognitive development, independent of the mother. When both parents had high levels of prenatal family stress, children displayed particularly poor nonverbal cognitive development. These findings emphasize the significance of parental prenatal family stress for child developmental outcomes.     

Executive functions in kindergarten children at risk for developmental coordination disorder

Executive functioning (EF) is a key cognitive process for development. Little is known about EF in Kindergarten children at risk for developmental coordination disorder (DCD), despite this age being one of the most critical and intensive period of motor and cognitive development. In our investigation we compared EF in kindergarten children at risk for DCD with Typically Developing (TD) children. Participants were 36 Italian children, 18 at risk for DCD (9 boys and 9 girls) who had a mean age of 4.6 years and 18 TD (9 boys and 9 girls) who had a mean age of 4.6. Executive functions were measured by tasks targeting cold executive functioning (working memory, fluency, inhibitory control) and two assessments of hot executive functioning (Snack Delay and Gift Wrap). Significant differences were found between children at risk for DCD and TD children on cold EF tasks of visuo-spatial working memory abilities, fluency and inhibitory control, but not on hot EF tasks. The findings suggest that it is advisable to implement preschool cognitively challenging physical activities programmes.     

Longitudinal association of child maltreatment and cognitive functioning: Implications for child development

Although research investigating associations among child maltreatment, cognitive functioning, and academic achievement has grown in recent years, important questions remain. In particular, assessing the influence of maltreatment apart from that of other co-occurring and confounding factors remains difficult. This study was developed to further the field’s understanding by investigating cognitive functioning in association with time-variant maltreatment patterns. Using multiple time-variant linear mixed models, we investigated the relationships between maltreatment timing and three domains of cognitive functioning (i.e., knowledge, comprehension, and analysis). In general, the cognitive functioning of students who experienced maltreatment was lower than that of their peers who had yet to experience maltreatment at the time of testing. Results of LMM indicated that the cognitive functioning of students who experienced maltreatment concurrent with the testing year fluctuated over time whereas the cognitive functioning of students who experienced maltreatment prior to or after the testing year remained stable. Students who experienced concurrent maltreatment showed the lowest functioning of any group. While maltreatment timing was a significant predictor of cognitive functioning over time, the addition of poverty into the model resulted in a non-significant effect of maltreatment timing. Additional research is needed to disentangle the longitudinal effect of maltreatment on cognitive functioning and address the interacting role of poverty and chronic maltreatment.     

Cognitive training in ADHD children: less to it than meets the eye

This article reviews cognitive training studies that have been carried out with children with attention deficit-hyperactivity disorder (ADHD) during the past decade. The efficacy of cognitive training as a single intervention and as an adjunct to stimulant treatment is discussed. The impact of training on the cognitive, academic, and behavioral functioning of youngsters with ADHD is summarized. Although this treatment modality is inherently appealing, there is little empirical support for its clinical utility with children with hyperactivity.     

Neurocognitive predictors of reading outcomes for children with reading disabilities

This study reports on several specific neurocognitive process predictors of reading outcomes for a sample of 278 children with reading disabilities. Three categories of response (i.e., poor, average, and good) were formed via growth curve models of six reading outcomes. Two nested discriminant function analyses were conducted to evaluate the predictive capability of the following models: (a) an intervention and phonological processing model that included intervention group, phonological awareness, and rapid naming and (b) an additive cognitive neuropsychological model that included measures of memory, visual processes, and cognitive or intellectual functioning. Over and above the substantial explanatory power of the base model, the additive model improved classification of poor and good responders. Several of the cognitive and neuropsychological variables predicted degree of reading outcomes, even after controlling for type of intervention, phonological awareness, and rapid naming.     

Improving sleep,cognitive functioning and academic performance with sleep education at school in children

We aimed at measuring the impact of a school-based sleep education program (ENSOM: ‘EN’ for ‘ENfant’ and SOM for ‘SOMmeil’ in French) on sleep, cognitive functioning and academic performance in children. In contrast with existing sleep education programs, ENSOM was designed by sleep experts with the intent of being autonomously achieved by teachers. One-hundred and thirty children aged 8–9 years took part in control versus ENSOM interventions. Compared to the control intervention, total sleep time was extended by 31 min per night, sleep efficiency improved by 2.9%, and sleep latency and wake after sleep onset were shortened by 7.7 and 4.5 min respectively after the ENSOM program. Sleep improvement remained significant at one-year follow-up. Attention, executive functioning, academic performance and parents' sleep knowledge also improved significantly. Given the frequency of sleep curtailment in children, school-based programs could be an efficient method to implement sleep education on a large scale.     

The teachability and effectiveness of cognitive self-regulation in sixth-grade writers

Seventy-one normally functioning Spanish sixth-grade students participated in classroom-based training in cognitive strategies for preplanning and substantive revision of expository text. Short essays completed by these students pre-intervention, post-intervention, and after a 12 week delay were compared with those of an ordinary-curriculum control (n = 24). Online, self-report process measures suggested that training resulted in a substantial and sustained increase in preplanning as a result of the intervention, but little increase in the extent to which students revised their text. Product measures indicated a substantial and sustained increase in text quality and improved use of coherence ties.     

Children and mothers in war: an outcome study of a psychosocial intervention program

The present study was designed to evaluate the effects on children (age: M = 5.5 years) in war-torn Bosnia and Herzegovina of a psychosocial intervention program consisting of weekly group meetings for mothers for 5 months. An additional aim was to investigate the children's psychosocial functioning and the mental health of their mothers. Internally displaced mother-child dyads were randomly assigned to an intervention group receiving psychosocial support and basic medical care (n = 42) or to a control group receiving medical care only (n = 45). Participants took part in interviews and tests to provide information about war exposure, mental health, psychosocial functioning, intellectual abilities, and physical health. Results showed that although all participants were exposed to severe trauma, their manifestations of distress varied considerably. The intervention program had a positive effect on mothers' mental health, children's weight gain, and several measures of children's psychosocial functioning and mental health, whereas there was no difference between the two groups on other measures. The findings have implications for policy.     

The Efficacy of Exergames Played Proximally and Over the Internet on Cognitive Functioning for Online Physical Education

Exergames (active video games that require kinesthetic movement) played in proximity to other players or against a gaming machine have been linked to positive increases in cognitive functioning. This study tested to see if remote exergame play over the Internet had an impact similar to exergames that are played in proximity. The study shows that remote exergaming can result in positive gains in cognitive functioning.     

Cognitive Control Predicts Academic Achievement in Kindergarten Children

Children's ability to shift behavior in response to changing environmental demands is critical for successful intellectual functioning. While the processes underlying the development of cognitive control have been thoroughly investigated, its functioning in an ecologically relevant setting such as school is less well understood. Given the alarming number of children who face failure in the U.S. school system, the purpose of this project is to determine whether subtly different measures of cognitive control differentially predict academic achievement. Sixty‐five kindergarten children were given two versions of a Dimensional Change Card Sort task—a geometric version followed by a linguistic version. Educational outcomes consisted of a standardized measure of academic achievement as well as assessments used by the school district. Results revealed that cognitive control, particularly as assessed by the linguistic variant, predicted children's academic performance on math and school‐based assessments, thereby suggesting that deficient cognitive control negatively impacts educational success.     

L’education cognitive à l’ecole

The acquaintance of the importance of cognitive tools for adaptation to our technological society that has a high degree of complexity joined to the important development of cognitive theories (from Piaget to information processing) has giving birth to an important streem of works that try to verify the influence of different forms of intervention on cognitive performance and develop a conception of cognitive education. Most works have focused on re-education methods, that means on methods intended for subjects presenting difficulties or backwardness in their cognitive functioning and being in different situations of failure. But, we must realize the importance, for all individuals, of developing to the highest degree their cognitive education at school intended to every body. This cognitive education must be preventive as much as remedial. In this article we describe what we think are the principles underlying that kind of cognitive education. These principles are not necessarily different from those underlying cognitive re-education but their importance and their applicability vary a lot in the two contexts.     

Preschooler Sleep Patterns Related to Cognitive and Adaptive Functioning

Research Findings: Preschoolers’ sleep patterns were examined related to cognitive and adaptive functioning. The sample consisted of 874 typically developing preschool children with a mean age of 40.01 months. Parent/caregiver reports of children's sleep pattern factors, Stanford-Binet 5 intelligence scale scores, and Behavior Assessment System for Children, Second Edition, adaptive behavior composite scores were examined. The results provided evidence of the interaction among preschoolers’ sleep factors, cognitive variations across performance areas, and adaptive functioning. Practice or Policy: Sleep needs vary according to the child, and maintaining optimal sleep habits will help preschool performance and skills acquisition. Practical implications for prevention, early intervention, education, and policy are discussed.     

Preventive Intervention and Outcome with Anxiously Attached Dyads

Anxiously attached 12-month-olds and their mothers as assessed in the Strange Situation were randomly assigned to an intervention and a control group to test the hypothesis that infant-parent psychotherapy can improve quality of attachment and social-emotional functioning. Securely attached dyads comprised a second control group. Intervention lasted 1 year and ended when the child was 24 months. ANOVAs were used to compare the research groups at outcome. Intervention group toddlers were significantly lower than anxious controls in avoidance, resistance, and anger. They were significantly higher than anxious controls in partnership with mother. Intervention mothers had higher scores than anxious controls in empathy and interactiveness with their children. There were no differences on the outcome measures between the intervention and the secure control groups. The groups did not differ in maternal child-rearing attitudes. Within the intervention group, level of therapeutic process was positively correlated with adaptive scores in child and mother outcome measures.     

Several CASE Lessons Can Improve Students’ Control of Variables Reasoning Scheme Ability

This study addressed one aspect of scientific reasoning, the control of variables reasoning scheme. We explored whether a short intervention aimed at accelerating this reasoning scheme by CASE lessons would improve students’ ability to apply this scheme in problems related to the biology curriculum. About 120 students from grade nine were assessed for their Piagetian cognitive level and were divided into two groups, control or intervention. A short intervention of three sessions took place in the intervention group only. Both groups were then instructed on the topic of enzymes according to the biology curriculum and undertook a final exam. The results showed that only 20% of the population acquired the Piagetian formal operations level, in line with previous findings. In addition, it was found that the short intervention had a significant effect on students’ ability to use the control of variables reasoning scheme.
