Developmental Outcome of Drug-Exposed Children Through 30 Months: A Comparison of Bayley and Bayley-II.

This study examined the effects of the Bayley Scales of Infant Development (BSID) version on developmental outcomes among drug-exposed children, some of whom received an intervention. Developmental outcome was evaluated with the BSID at 12 and 18 months and with the BSID-II at 24 and 30 months. In the repeated measures analyses, children scored higher on the BSID Mental Developmental Index (MDI; p     

Relation between mastery behavior in infancy and competence in early childhood.

The copyright note has been corrected and is included in the erratum.] 53 infants were observed at 6 and 12 mo of age during 2 24-min play sessions. The Bayley Scales of Infant Development (BSID) were given at 6 and 12 mo and the McCarthy Scales of Children's Abilities (MSCA) at 30 mo of age. Results reveal that measures of competence in infancy (successful task completion during play and the BSID scores) were not strongly correlated with the 30-mo MSCA scores. In contrast, infant mastery behavior during play strongly predicted MSCA scores: The time spent investigating toys at 6 mo and persistence in solving tasks at 12 mo of age were behaviors significantly positively correlated with the MSCA scales. It is suggested that infant behaviors that predict later competence do not remain static but change with age and that infants' mastery behavior is a more effective predictor of later development than their competence with either toys or developmental tests.

évaluation du développement de l'enfant au cours de la première année: l'utilisation de regroupements d'items du Bayley.

Compared the discriminative powers of (1) the mental and motor indexes of the Bayley Scales of Infant Development (BSID) (N. Bayley, 1969), (2) the 5-cluster regrouping of the BSID by R. Kohen-Raz (1967), and (3) the 7-cluster regrouping of the BSID by L. J. Yarrow et al (1975). Ss were 29 3.5-mo-old, 53 6-mo-old, and 57 9-mo-old Haitian, Canadian, and Vietnamese infants. Ss' performances on the BSID were analyzed with the mental and motor scales of the BSID, the 5-cluster regrouping, and the 7-cluster regrouping. The 3 systems were compared with regard to their ability to detect age, gender, and cultural differences. (English abstract) (PsycINFO Database Record (c) 2010 APA, all rights reserved)

What are we testing?

A measure that samples both the sophistication of infants' behaviors and infants' propensity to demonstrate their most sophisticated repertoire of skills was developed and tested for predictability of infant functioning across a 6-mo time span. This measure of spontaneous mastery, unlike a measure of executive capacity with which it is compared, was highly stable across 6 mo. Spontaneous mastery scores of 38 12-mo-olds predicted 18-mo-old performance on the Mental Development Index (MDI) of the Bayley Scales of Infant Development as well as the Bayley scale itself. Common to both the spontaneous mastery measure and the Bayley MDI is the construct of mastery leading toward developmental competence, suggesting that the more proficient children are at mastering tasks on their own, the more inclined they might be to maximize their potentials in testing and learning environments. The greater predictability of the spontaneous mastery measure suggests a means for elucidating individual differences in the motivation–competence relationship that remain stable across developmental epochs.

A relationship between leader intelligence and leader rated effectiveness.

Conceptualizes intelligence as the leader's ability to integrate his experience and thus provide him with skills to deal effectively with the technical aspects of tasks and interpersonal relationships. In 4 studies, 55 sergeants in charge of field artillery sections, 55 navy petty officers, 58 unit commanders, and 52 sergeants in charge of army mess units completed the least preferred co-worker scale (LPC), a group atmosphere scale, a shortened version of the Henmon-Nelson Tests of Mental Ability, and ratings of situational favorableness on 3 dimensions (leader-member relations, task structure, and position power). Ratings of leader performance were completed by 2-3 superiors. Results indicate that the relationship between leader intelligence and performance depended on the leader's motivational style (LPC), his experience, and the leader-member relations.

The effects of perinatal hypoxic risk on developmental outcome in early and middle childhood: A twin study.

The goal of this study of 66 twins was to determine whether motor and cognitive functions assessed in early and middle childhood are vulnerable to perinatal hypoxic risk. In an earlier study of 76 infant and toddler twins (S. Raz, F. Shah, & C. Sander, 1996), the authors found that intrapair discrepancy on the Mental Developmental Index, but not on the Psychomotor Developmental Index, of the Bayley Scales of Infant Development was associated with discordance for perinatal hypoxic risk. The twins at lower risk outperformed their higher risk co-twins. In the present study the authors sought to establish in a new sample of preschool and school-age twins whether gaps in performance persist into early and middle childhood. Although the disparity in hypoxic risk between the co-twins was typically moderate, significant intrapair differences were observed on the measure of motor performance. Among the motor abilities examined, skills involving visually guided ballistic arm movements appeared to be the most vulnerable to perinatal risk.

Assessment of mastery motivation during the first year of life: Contemporaneous and cross-age relationships.

Assessed 68 firstborns at 6 and 12 mo with 12 mastery tasks chosen to elicit 3 aspects of mastery motivation: effect production, practicing sensorimotor skills, and problem solving. Ss were also administered the Bayley Scales of Infant Development (BSID). The significant contemporaneous and cross-age relationships suggest complex interactions at 6 and 12 mo between each S's developmental level, nature of the task, and mastery motivation. The cross-age relationships indicate a developmental progression in mastery behavior during the 1st yr. This progression is one in which a highly motivated child is persistent in producing effects at 6 mo, becomes persistent in practicing sensorimotor skills, and engages in exploration of problem-solving tasks at 12 mo. The relationships with the BSID suggest that mastery motivation and developmental competence are interrelated and that mastery becomes more differentiated with age.

Screening for principal versus comorbid conditions in psychiatric outpatients with the Psychiatric Diagnostic Screening Questionnaire.

In examining the performance of screening scales, a distinction should be made between principal and additional diagnoses. The Psychiatric Diagnostic Screening Questionnaire (PDSQ) is a brief, psychometrically strong self-report scale designed to screen for the most common Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV) Axis I disorders encountered in outpatient mental health settings. In the present report, the authors compared the performance of the PDSQ in identifying principal and comorbid disorders. Seven hundred ninety-nine psychiatric outpatients completed the PDSQ and were interviewed with the Structured Clinical Interview for DSM-IV. The sensitivity and negative predictive values of the PDSQ subscales were similar for principal and additional diagnoses. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Early home environment and changes in mental test performance in children from 6 to 36 months.

Administered the Bayley Scales of Infant Development at 6 mo and the Stanford-Binet Intelligence Scale at 3 yrs to 77 normal children. When each S was 6 mo old, the family was observed and interviewed using the Home Observation for Measurement of the Environment (HOME), a measure of the quality of stimulation in the early environment. A difference of 21 or more points between a S's 6-mo Bayley Mental Development Index score and 3-yr Stanford-Binet score was used to determine whether the S had increased, remained stable, or decreased in mental test performance. Multiple discriminant analyses were done using the 6 subscales of the HOME inventory to differentiate among increasers, nonchangers, and decreasers. Increases in test performance were related to 2 subscales, Maternal Involvement with Child and Provision of Appropriate Play Materials. Decreases were related to inadequate Organization of Physical and Temporal Environment. Results indicate that home environment may contribute to instability of performance on infant tests. Results are in agreement with the findings of R. B. McCall et al (see record 1975-04922-001) regarding gains for 21/2-17 yr olds, except that the parents' method of discipline may not be quite so important for infants.

Acclimation of the photosynthetic response of Chromatium vinosum to light-limiting conditions

The predictive value of the Neonatal Neurological Examination (NNE) adapted from Prechtl (1977) and the Infant Motor Screen (IMS) from Nickel (1989) at 4 months was studied in severely jaundiced infants in Zimbabwe. Fifty infants were examined with the NNE, 41 with the IMS and 43 with the Bayley Scales of Infant Development (BSID) (Bayley 1969). Five infants had choreoathetosis and six had a motor delay at age 1 year. The NNE and IMS proved to be sensitive instruments particularly when two infants who became malnourished after the neonatal period were excluded. Logistic regression was used to investigate the relation between the BSID and five selected predictors from the NNE. This resulted in a correct classification of 93%. By using only the predictors acoustic blink and traction response, 80% of the infants were correctly classified but the number of false negatives was reduced from three to one.     

Relationship of prenatal cocaine exposure and maternal postpartum psychological distress to child developmental outcome

Maternal cocaine use during pregnancy can affect the infant directly through toxic effects or indirectly through cocaine's influence on maternal psychological status. We followed 160 cocaine exposed and 56 nonexposed infants and their mothers identified at birth through interview and/or urine screen. Although cocaine exposure defined the groups, infant exposure to alcohol, marijuana, and tobacco was allowed to vary. Infants were 99% African American and poor. All mothers completed the Brief Symptom Inventory (BSI) and infants were given the Bayley Scales of Mental (MDI) and Motor (PDI) Development at a mean corrected age of 17 +/- 8 months. Both MDIs (94 +/- 17 vs. 103 +/- 16) and PDIs (101 +/- 16 vs. 108 +/- 12) were lower for cocaine exposed infants. Psychological distress was greater in cocaine using mothers. Hierarchical multiple regression was used to assess the relative effects of gestational age, maternal psychological distress, and cocaine and polydrug exposure on infant outcomes. Both psychological distress and cocaine and alcohol exposure predicted lower MDIs after controlling for prematurity. Neither psychological distress nor alcohol exposure predicted motor outcome, while cocaine had a significant effect. Tobacco and marijuana exposure were unrelated to outcome. These findings provide further support for direct effects of cocaine and alcohol on infant development as well as highlight the need for studies to document maternal psychological factors, which may increase child risk for poorer outcomes.     

The relationship between socioeconomic status, hostility, and blood pressure reactions to mental stress in men: Data from the Whitehall II study.

This study investigated the relationship among blood pressure reactions to mental stress, cynical hostility, and socioeconomic status (SES) in 1,091 male public servants. Occupational grade served to index SES and cynical hostility was assessed using the Cook-Medley scale. (Cook & Medley, 1954). The magnitude of systolic, but not diastolic, blood pressure change scores to stress was positively associated with occupational grade: the higher the grade, the greater the reactions. Mental stress task performance also varied with occupational grade but was unrelated to reactivity. Ratings of task difficulty did not vary with occupational grade. Cynical hostility was negatively related to occupational grade, and, contrary to previous findings, negatively related to systolic blood pressure reactivity. Cynical hostility was also negatively related to mental stress task performance but unrelated to ratings of task difficulty. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Genetic and environmental influences on the rate of communicative development in the first year of life.

Used a full adoption design to investigate the separate effects of heredity and environment on differences in the rate of communicative development of 50 adopted 1-yr-olds. Measures of infant communicative performance were obtained, along with behavioral measures, from the infants' birth mothers and adoptive parents. The adoptive home environment also was assessed. Results indicate that 19% of the correlational relationships between cognitive abilities of the birth mother and communicative performance of the infant were significant, suggesting some genetic influence on rate of communicative development in the 1st yr. In contrast, an average of 5% of the correlational relationships between the infant and cognitive abilities of both adoptive parents were significant. However, 2 measures of maternal behavior (as assessed from videotape records taken in the adoptive home) were significantly related to overall communicative performance of the infant. These were contingent vocal responsivity to infant vocalizations and vocal imitation. (37 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Age differences in the speed of mental rotation.

66 Ss in 4 age groups (mean ages 20.9, 32.4, 50.9, and 63.3 yrs) participated in a mental rotation task for 4 consecutive days. ANOVAs revealed significant age differences in the linear function relating median RT to degrees of rotation: Older Ss had higher intercepts and higher slopes. There were no significant age differences in error rates. Practice reduced slopes and intercepts for all groups, but it neither eliminated nor systematically reduced age differences in mental rotation performance. Mental rotation slopes and intercepts were significantly correlated with performance on the Figures subtest of the Primary Mental Abilities Test but not the Vocabulary subtest of the Nelson-Denny Reading Test. Results point toward age changes in the speed of spatial information processing that may contribute to age changes in performance on tests of spatial ability.

Semantic development of African-American children prenatally exposed to cocaine

Semantic content categories were described for the single word, multiple word, and verb relation utterances of 22 African-American 2-year-olds during a 90-min laboratory session. Half of the toddlers had been exposed prenatally to cocaine and half were unexposed, as documented by biological assay in the newborn period. The exposed and unexposed groups were carefully matched on demographic, medical, and proximal caregiving variables. Children's spontaneous utterances were transcribed from audio- and videotapes during the laboratory session and scored for semantic features by a team of reliable coders who were masked to child exposure status. General productive language features (utterance length, verbosity, and intelligibility) were also assessed. To evaluate general language and cognitive skills, the toddlers were evaluated with the Sequenced Inventory of Communicative Development-Revised (SICD-R) and the Bayley Scales of Infant Development (BSID). Although exposed and nonexposed toddlers exhibited similar sequences of semantic development, the exposed toddlers were more restricted and delayed in their semantic representations. No significant group differences were observed, however, for structural features of language (e.g., utterance length, distribution of utterance types) or for children's general language and cognitive functioning as assessed by standardized assessments (i.e., SICD-R, BSID). Thus, a history of prenatal cocaine exposure and associated risk factors (e.g., prenatal exposure to alcohol, diminished birth weight) are related to delays in early semantic development. Proposed diagnostic and treatment strategies are discussed.     

Retardation and twin concordance in infant mental development: a reassessment

A reappraisal is made of Nichols and Broman's conclusion that there is no evidence that genetic influences are important in infant mental development if severely retarded twins are excluded from the sample. The reappraisal touches on certain idiosyncrasies of their sample, the test scores reported, and their definition of severe retardation. Data are presented for a sample of White twins who have been followed longitudinally since birth. For Bayley Mental Scale scores at 9 months of age, the monozygotic within-pair correlation was 0.85 and the dizygotic within-pair correlation was 0.62. With 13 retarded twins excluded, the correlations became 0.81 and 0.64, respectively, with the monozygotic correlation still being significantly larger (p less than 0.01). The present results indicate that genetic factors play a role in infant mental development.     

The mental status characteristics of patients with peptic ulcer and chronic cholecystitis

Mental status examinations (V. P. Za?tsev's clinical scale. MMPI test modified by F. B. Berezin et al.) were performed in 90 patients with duodenal ulcer (DU) and 142 patients with chronic acalculous cholecystitis (CAC). Mental changes were revealed in 93.3% and 86.6% of DU and CAC patients, respectively, in the disease aggravation. These changes persisted more continuously in CAC patients as they remained after the disease treatment unlike those in DU. Therefore, mental status of CAC patients needs correction.     

Paired-associate learning and recall of high and low imagery words: moderating effects of hypnosis, hypnotic susceptibility level, and visualization abilities

Relationships between recall of low and high imagery paired-associate (P-A) words and hypnotic susceptibility, and the influence of hypnosis on recall as moderated by hypnotic level were examined. Subjects were assessed on 2 hypnotic susceptibility scales [Harvard Group Scale of Hypnotic Susceptibility; Stanford Hypnotic Susceptibility Scale, Form C (SHSS:C)]. Forty-one low (0-4 SHSS:C) and 41 highly (9-12 SHSS:C) hypnotizable college students were assigned to 1 of 4 experimental groups: waking-hypnosis, hypnosis-waking, waking-waking, or hypnosis-hypnosis. Recall was significantly better for high than low imagery words. In the more sensitive within-subjects design, high hypnotizables recalled more P-A words during hypnosis than waking, and lows did not differ. In the between-subjects design, hypnotic level was not a moderator of performance during hypnosis. Low hypnotizables recalled more words in the within-subjects design. Visualization ability was a poor moderator of imagery-mediated learning. High imagery recall correlated significantly with Marks's (1973) Vividness of Visual Imagery Questionnaire (.25) and Paivio and Harshman's (1983) Individual Differences Questionnaire (IDQ) Verbal scale (.29), but not with the IDQ Imagery scale, the Mental Rotations Test (Vandenberg & Kuse, 1973), or the revised Minnesota Paper Form Board Test (Likert & Quasha, 1941).
