THE RELIABILITY OF BAYLEY'S REVISED SCALE OF MENTAL AND MOTOR DEVELOPMENT DURING THE FIRST YEAR OF LIFE

Emmy Werner; Nancy Bayley

A tester-observer and test-retest reliability study of Bayleys Revised Scales of Mental and Motor Development with eight months old infants yielded the following results: (1) Mental Scale items with high tester-observer and high test-retest reliabilities deal with object-oriented behavior; (2) Mental Scale items with low test-retest reliabilities require social interaction; (3) Motor Scale items with high tester-observer and high test-retest reliabilities deal with independent control of head, trunk, and extremities; (4) Motor Scale items with low test-retest reliability require assistance by an adult. The implications of the findings for early diagnosis of neural malfunctioning are discussed.

LEARNING IN ADULTHOOD: THE ROLE OF INTELLIGENCE

Nancy Bayley

Publisher Summary This chapter discusses learning in adulthood and the role of intelligence. It discusses the kinds of intellectual abilities that show growth into adulthood and the way in which these are related to concept learning. The chapter also highlights the implications for the teaching of concepts to adults and presents a comparison of the findings from the Terman study and those from the Berkeley Growth Study. The chapter focuses on general growth trends in increment or decrement in intelligence over the 20-year age span between 16 and 36 years. It presents correlations between test ages the six verbal scales in the chapter. In the chart presented in the chapter, the tests are arranged approximately in the order of least to most change in the content of the WAIS Scale from its counterpart in the Wechsler–Bellevue. Greater consistency is seen over this young adult age span in both short- and long-range scores among the males, and for the males most clearly in vocabulary and information, and to a lesser extent in similarities, digit symbol, and block design. These tend also to be the tests that show continuing increments in capacity for both sexes through 36 years.

Growth pattern shifts in healthy children: Spontaneous and induced

Leona M. Bayer; Nancy Bayley

Twenty “short” skeletally retarded children were treated for brief periods with small dosesof the newer nonandrogenic steroids. Their longitudinal records were studied for evidence of the immediate and long-term effects on height. Evaluations were based on the shapes of height-age curves, on fluctuations in growth rate, on successive height predictions, and on actual mature height where it was known. Spontaneous changes in the 6 most variable growth patterns among 100 children in a normal untreated sample provided controls for the clinical observations. The immediate growth rate in prepuberal children was almost always accelerated. The long-term prediction shifts in these treated children (from −2.3 inches to +5.9 inches) compare favorably with the spontaneous shifts in the most variable norms (from −3.7 inches to +4.5 inches).

Motor development and decline.

Nancy Bayley; Anna Espenschade

CURRENTLY, there is an increasing professional and general interest in the changes which take place in later life. It has, therefore, seemed pertinent to include in this chapter references to researches which are concerned with age changes in motor abilities thruout the entire life span. Motor abilities cover a wide range from large-muscle coordinations, strength and balance or postural control, to fine manual coordinations involving speed and dexterity; from simple reactions to complex, highlyspecialized patterns of reaction, including vocational and athletic skills. Numerous studies concerned with specific manual skills of young adults where there is no consideration of changes with age, and which are primarily concerned with learning, even tho the tasks involved are motor in nature, have been excluded from this survey. However, a few studies on laterality which give information on developmental changes have been included. Altho the age range has been extended and the field broadened, the total number of investigations reported in this area of motor performance has declined during the past three years below that of the preceding three-year period. In fact, the number of references cited in the successive chapters on motor development in the REVIEWS on Growth and Development, has shown a steady decline since the first one appeared in 1941.

Chapter II: Motor Development from Birth to Maturity

Nancy Bayley; Anna Espenschade

I N THE FIELD OF MOTOR DEVELOPMENT during the last few years attention has been focused primarily on studies of the early stages of neuro-muscular development, on studies of age changes and developmental sequences in motor coordinations, and on the standardization of tests of motor skills. There have also been a number of analytical studies concerned with the nature and components of motor abilities.
