Attention,Response Inhibition,and Face-Information Processing in Children: The Role of Task Characteristics,Age, and Gender

The aim of the study was to assess: (a) developmental changes in attention, response inhibition, and face-information processing using the new Balloons task and (b) to evaluate the association between measures derived from the task with reported behavior problems. One hundred and thirty-four typically developing children (53 boys and 81 girls) were tested with the Balloons. Their parents and teachers completed the Child Behavior Checklist. Our results validate the Balloons as a reliable task with significant effects of manipulations in difficulty level (speed, processing load, and processing type). The results suggest that face-information processing undergoes significant changes during the age period between 7 and 13 years with significant gender differences. Modest but significant correlations were found between the Balloons' measures and behavior problems.     

Behavior Rating Inventory of Executive Function – Preschool Version (BRIEF-P): Test Review and Clinical Guidelines for Use

The Behavior Rating Inventory of Executive Function-Preschool Version (BRIEF-P) is a standardized questionnaire that measures executive functioning in preschoolers. This test review provides an overview of the BRIEF-P, including scale structure, administration, norms, score interpretation, current reliability and validity evidence, and provides general guidelines for clinical use.     

Complementary assessments of executive function in preterm and full-term preschoolers

Executive functions (EFs) are interrelated cognitive processes that have been studied in relation to behavior, attention, academic achievement, and developmental disorders. Studies of EF skills assessed through parent report and performance-based measures show correlations between them ranging from none to modest. Few studies have examined the relationship between EF skills measured through parent report and performance-based measures in relation to adaptive function. The present study included preschool children born preterm as a population at high risk for EF impairments. Preschool children (N = 149) completed a battery of EF tasks that assess working memory, response inhibition, idea generation, and attention shifting or cognitive flexibility. Parents reported on children’s EF and adaptive skills. Preterm children showed more parent-rated and performance-based EF impairments than did full-term children. The combined use of either parent report or performance-based measures resulted in the identification of a large number of children at risk for EF impairment, especially in the preterm group. Both parent report and performance-based EF measures were associated with children’s adaptive function. EF skills are measurable in young child'ren, and we suggest that EF skills may serve as targets for intervention to improve functional outcomes. We recommend the use of both parent report and performance-based measures to characterize children’s EF profiles and to customize treatment.     

A normative study of the Children’s Color Trails Test (CCTT) in the Cypriot population

Background: The Children’s Color Trails Test (CCTT) is a neuropsychological test that measures attention, divided attention, and speed of mental processing. It has been increasingly used in the assessment of children in cross-cultural environments for neurological and psychiatric disorders such as seizures and closed head injuries, learning and/or language disabilities, attention deficit/hyperactivity disorder, children with manganese exposure, and children diagnosed with HIV virus. However, there is a paucity of studies presenting normative data. The aim of the present study was to provide normative data for the CCTT in the Cypriot population. Methods: A total of 709 native Cypriot children aged 7–16 years, recruited from various public schools across the island, took part in the study. Exclusion criteria involved the existence of neurological, psychiatric, cardiological, and metabolic diseases, premature birth, history of maternal alcohol and drug abuse during pregnancy, low birth weight, hearing loss, visual problems, native language other than Greek, and abnormality in fine-motor movements. Results: Age and gender were found to be important factors for the interpretation of scores in all CCTT variables. Older children required less time and exhibited fewer errors, near misses, and prompts compared to younger children. There was a consistent pattern of a 3–4 seconds improvement (less time in seconds) in the CCTT completion time as age increased. Conclusions: CCTT is a promising tool for the measurement of attention in the native Cypriot population. Further research is needed in children diagnosed with various neurological and psychiatric diseases in order to estimate validity of the CCTT in clinical populations.     

Parenting,corpus callosum,and executive function in preschool children

In this longitudinal population-based study (N?=?544), we investigated whether early parenting and corpus callosum length predict child executive function abilities at 4 years of age. The length of the corpus callosum in infancy was measured using postnatal cranial ultrasounds at 6 weeks of age. At 3 years, two aspects of parenting were observed: maternal sensitivity during a teaching task and maternal discipline style during a discipline task. Parents rated executive function problems at 4 years of age in five domains of inhibition, shifting, emotional control, working memory, and planning/organizing, using the Behavior Rating Inventory of Executive Function-Preschool Version. Maternal sensitivity predicted less executive function problems at preschool age. A significant interaction was found between corpus callosum length in infancy and maternal use of positive discipline to determine child inhibition problems: The association between a relatively shorter corpus callosum in infancy and child inhibition problems was reduced in children who experienced more positive discipline. Our results point to the buffering potential of positive parenting for children with biological vulnerability.     

Charting the Developmental Trajectories of Attention and Executive Function in Chinese School-Aged Children

Attention is a complex domain that has reawakened research interest in recent years. There are relatively few studies that have examined age-related changes across different attention subcomponents, such as selection, maintenance, and control, using large samples covering a wide age range. The present study assessed performance in 466 participants in order to identify the ages at which mature performance was reached across differing attention subcomponents. Furthermore, we investigated whether the nature of the attentional demands or task difficulty predicted the age at which stable levels of performance were reached. The results supported the former rather than the latter alternative.     

Characterization of Children's Decision Making: Sensitivity to Punishment Frequency,Not Task Complexity

On a gambling task that models real-life decision making, children between ages 7 and 12 perform like patients with bilateral lesions of the ventromedial prefrontal cortex (VMPFC), opting for choices that yield high immediate gains in spite of higher future losses (Crone &; Van der Molen, 2004 Crone, E. A. and Van der Molen, M. W. 2004. Developmental changes in decision-making: Performance on a gambling task previously shown to rely on ventromedial prefrontal cortex. Developmental Neuropsychology, 25(3): 251–279. [PUBMED][INFOTRIEVE][CROSSREF][Taylor &; Francis Online], [Web of Science ®] , [Google Scholar]). The current study set out to characterize developmental changes in decision making by varying task complexity and punishment frequency. Three age groups (7–9 years, 10–12 years, 13–15 years) performed two versions of a computerized variant of the original Iowa gambling task. Task complexity was manipulated by varying the number of choices participants could make. Punishment frequency was manipulated by varying the frequency of delayed punishment. Results showed a developmental increase in the sensitivity to future consequences, which was present only when the punishment was presented infrequently. These results could not be explained by differential sensitivity to task complexity, hypersensitivity to reward, or failure to switch response set after receiving punishment. There was a general pattern of boys outperforming girls by making more advantageous choices over the course of the task. In conclusion, 7–12-year-old children—like VMPFC patients—appear myopic about the future except when the potential for future punishment is high.     

The Acquisition and Function of Religious Beliefs: A Review and Synthesis of Proximate and Ultimate Perspectives

ABSTRACT

Two main scientific approaches have renewed in the last decade the scientific study of religion: the cognitive and the adaptationist. The former is focused on proximate causes, the latter is looking for ultimate causes of religious beliefs and behaviours. Both approaches are useful and promising. However, in both cases, various important aspects and contexts associated with the origin, acquisition, and transmission of religious beliefs have been neglected. The present paper offers an approach that conjoins both models after reviewing several critical issues, to highlight a distinction between cognitive conditions and structures, on one side; and developments or applications, on the other. As a result greater attention needs to be paid to religious functions and their cultural framework to better understand religion and to explain some current processes, like massive secularization in several areas.     

心理负荷的评估:基于神经人因学的视角

心理负荷的评估正经历着从传统工效学向神经人因学的变革.EEG、ERPs、fMRI、fNIRS和TCD等神经科学研究技术为这场变革提供了有力的工具.研究发现:在单任务情境下,随着操作者心理负荷的增加,脑电α波活动减弱,θ波活动增强,并且前额皮层血流、左侧额下回血液氧合血红蛋白浓度变化均增加,大脑动脉血流速度也增快;在双任务情境下,随着操作者主任务心理负荷的增加,次任务的N1、新异P3和P3b等ERPs成分波幅降低.依据这些研究成果,学者们利用人工神经网络、支持向量机等模式分类算法实现了对心理负荷的实时在线评估.但是,各种研究技术在敏感性、诊断力、主任务干扰、实施需求、可接受性和信度等方面各有优势与不足.在未来研究中,要注意促进相关技术的融合、提高其可接受性,并充分利用模式识别算法提高其诊断力和敏感性.
