One problem which can be observed in the field of EFL/ESL learning is that a number of English major BA and MA students are not highly committed to their major and decide not to continue their graduate studies. Sometimes even graduate students from English majors prefer to extend their education or work in an unrelated field. This might be…

The study of dyadic interaction plays a major role in infancy research. To advance conceptually informed measurement of dyadic interaction and integration across studies, we examined factor structure of individual parents' and infants' measures and dyadic measures from face-to-face interactions in two samples of 6-month-old infants and…

This study describes the development and psychometric properties of the Counseling Supervisor's Behavior Questionnaire, designed to assess the specific behaviors of supervisors, which can be observed by supervisees during supervision sessions. Factor structure, construct and concurrent validity, and internal consistency reliability of the…

Objective: To chart the emergence of precursors and early signs of autism spectrum disorder (ASD) and autistic traits in the Avon Longitudinal Study of Parents and Children, a prospective longitudinal cohort study of the surviving offspring of 14,541 pregnant women from southwestern England with an expected delivery date between April 1991 and…

A factor analysis was performed on the behavioral items of the Brazelton Neonatal Assessment Scale for an urban population of 328 newborns. (Author/JMB)

The dimensional structure of infants' behavioral repertoire was shown to be highly stable over 3 to 15 months of age. Factor analysis of parent questionnaire data produced seven factors named Intensity/Activity, Regularity, Approach-Withdrawal, Sensory Sensitivity, Attentiveness, Manageability and Sensitivity to New Food. An eighth factor,…

The purpose of the study was to establish dimensions of functioning accounting for interindividual variation in behavior in the later infancy period and to investigate the stability of the dimensional structure during the infancy period. Factor analyses were performed on parent questionnaire data for 357 infants, aged 11 to 15 months. An 8-factor…

The purpose of this study was to apply factor analysis techniques to delineate dimensions of early infant behavior and to establish categories of functioning which can be seen as a source of individuality in early childhood. Data about the behavior of 791 infants in two age groups (11-25 weeks and 26-41 weeks) were obtained using a questionnaire…

Examines the psychometric properties of two procedures for reducing data from the Brazelton Neonatal Behavioral Assessment Scale: factor and cluster analysis. The sample consisted of 85 male and 77 female newborns. (RH)

Examined differences in acoustic characteristics of cries, both early and late, within a prolonged crying bout. Results indicated that late cries appeared to result from a smaller number of factors than did early cries. Results support notions that crying bouts settle into a regular cry with acoustic features matching a theoretical model of cry…

In order to specify the factor structure and stability of infant and maternal behavior, mother/infant interaction was observed when infants were 12 and 24 months of age. Mothers and infants observed in dyadic interaction in a playroom during a 15-minute free play period represented a heterogeneous sample across gender, socioeconomic status, and…

Ninety-two clinically normal infants (48 male, 44 female) were tested at 2 and 90 days of age to examine the continuity of newborn behavior through early infancy across a broad range of behaviors. (MP)

Measures of active sleep, quiet sleep, sucking, crying, body size and gestational age were factor analyzed for 137 normal newborns at 2 days of age. The results yielded 3 stable factors: reactivity-irritability, maturity, and reflexive and discriminative sucking. (JMB)

This paper discusses the development of instruments to measure individual differences in behavior during infancy. The Infant Temperament Questionnaire (ITQ), which was designed to measure the temperament dimensions identified by the New York Longitudinal Study (NYLS), constituted the methodological starting point in the search for a dimensional…

Discusses differences in results of factor analyses of ten diverse samples which have been studied using the Brazelton Neonatal Behavioral Assessment Scale (NBAS). Concludes that a single common factor structure accounts for the intercorrelations among NBAS items. (Author/BH)
