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.     

The play behavior of hearing-impaired kindergarten children

This exploratory study examined the cognitive and social play behaviors of hearing-impaired kindergarten children with regard to classroom instructional mode and communication strategies. Two classes were observed--one using sign communication and the other using an oral-based method of communication. Functional, constructive, dramatic, and social play behaviors were observed and documented. Statistically significant differences were found between the two groups of children with regard to social and dramatic play as well as with regard to levels of aggression. For example, children in the sign-based class demonstrated higher levels of social play behavior and lower levels of aggression than the children in the oral-based class. Guidelines and strategies to help children initiate and sustain play are suggested.     

Early identification of developmentally disabled and at-risk preschool children.

This study examined child-centered data (from birth to 7 years) and familial factors as possible predictors of disabilities in adolescence. The sample was taken from original participants in the National Collaborative Perinatal Project in Rhode Island who were also judged as handicapped after school entry. Results of the current study indicated that parental traits (i.e., maternal education) are more accurate predictors of adolescent status than the child's own behavior from birth to 3 years, whereas child-centered skills assessed at 4 and 7 years of age are better predictors than are familial factors. Overall, data suggest that early identification models which focus upon developmental delay or adverse medical events from birth to 3 years of age are inadequate in fully identifying children eventually judged to be handicapped. Screening initiatives must be developed that are multivariate (child and family focused) and account for differential weights of risk factors over time.     

Preliminary norms and technical data for use of the Revised-Children's Manifest Anxiety Scale with kindergarten children

The Revised-Children's Manifest Anxiety Scale (Reynolds & Richmond, 1978) was administered to 97 kindergarten children. Coefficient alpha reliabilities of .79 for males (N = 53), .85 for females (N = 44), and .82 for the total sample resulted. Contrary to findings with older children, no sex differences occurred in scoring on the anxiety scale. The kindergarten children generally scored higher on the anxiety scale than did older children. Lie scale scores were comparable to those of other primary grade children. Implications for use of the scale with young children are discussed.     

The effects of the use of activities of sapa on the oral communication skills of disadvantaged kindergarten children

The study investigated the effects of participation in the activities of Science-A Process Approach (SAPA) on the oral communication skills of disadvantaged kindergarten children. Experimental-control group, pretest-posttest research design was employed. The investigator designed the Test of Oral Communication Skills (TOCS) to measure students' oral communication skills. Two experimental groups (one morning and one afternoon, N = 52) and two control groups (one morning and one afternoon, N = 48) were randomly assigned from two kindergarten classrooms (morning and afternoon classes in each) in an inner-city school in Columbus, Ohio. The investigator provided the science instruction to all students. Experimental subjects received 22 half-hour lessons from exercises a through k of Part A, SAPA. Control subjects received 22 lessons from Springboards to Science, a teacher demonstration, class discussion type of kindergarten curricuoum used in the school system. The treatment period spanned 12 academic weeks. Analysis of variance of TOCS pretest scores showed no significant differences among any of the means of the four groups. Analysis of covariance of TOCS posttest scores revealed differences significant at .05 or beyond in the mean scores of the experimental groups and control groups for total oral and total receiving skills and for six of the eight subskills measured by TOCS. Application of the Tukey (b) test revealed that experimental group mean scores exceeded control group mean scores in every TOCS skill and subskill area and that in total oral transmitting subskills both experimental group mean scores were significantly greater at .05 level or beyond than corresponding mean scores for both control groups. Within the parameters of this study, it may be concluded that when the activities and teaching strategies of SAPA curriculum are presented to disadvantaged kindergarten children, their oral communication skills, especially the transmitting (speaking) skills, are clearly enhanced.     

The use of a dynamic screening of phonological awareness to predict risk for reading disabilities in kindergarten children

This study examined the usefulness and predictive validity of a dynamic screening of phonological awareness in two samples of kindergarten children. In one sample (n = 90), the predictive validity of the dynamic assessment was compared to a static version of the same screening measure. In the second sample (n = 96), the dynamic screening measure was compared to a commonly used screening tool, Dynamic Indicators of Basic Early Literacy Skills Initial Sound Fluency. Results showed that the dynamic screening measure uniquely predicted end-of-year reading achievement and outcomes in both samples. These results provide preliminary support for the usefulness of a dynamic screening measure of phonological awareness for kindergarten students.     

Predicting academic performance of Anglo and Mexican-American kindergarten children

Sixty-two kindergarten children from three cultural/language backgrounds (Anglo, English-speaking; Mexican-American, English-speaking; and Mexican-American, Spanish-speaking) were screened for school readiness with three techniques: a series of Piagetian-based mathematical tasks, a number proficiency measure, and kindergarten teachers' ratings. One year later, first-grade performance was assessed through standardized tests and teachers' ratings. The predictive accuracy of kindergarten measures varied according to ethnicity and language background of the children. Kindergarten measures were significantly predictive of Anglo English speakers, but were somewhat less accurate for the Mexican-American English-speaking group. Importantly, the kindergarten measures, including the teachers' ratings, were generally nonpredictive for Mexican-American Spanish speakers, although the tests were not language or culture specific. The importance of language as a factor in school screening is underscored. Findings raise serious questions as to the appropriateness of early screening of children from different language and cultural backgrounds.
