ANS: A
The first pattern of development is in the head-to-tail, or cephalocaudal, direction. The head end of the organism develops first and is large and complex, whereas the lower end is smaller and simpler, and development takes place at a later time. Proximodistal, or near-to-far, is the second pattern of development. Limb buds develop before fingers and toes. Postnatally, the child has control of the shoulder before achieving mastery of the hands. Mass to specific is not a pattern of development. In all dimensions of growth, a definite, sequential pattern is followed.
ANS: A
Sensitive periods are limited times during the process of growth when the organism will interact with a particular environment in a specific manner. These times make the organism more susceptible to positive or negative influences. The sequential period, terminal points, and differentiation points are developmental times that do not make the organism more susceptible to environmental interaction.
ANS: B
In general, birth weight triples by the end of the first year of life. For an infant who was 3 kg at birth, 9 kg would be the anticipated weight at the first birthday. A weight of 6 kg is below what one would anticipate, and weights of 12 and 15 kg are above what would be expected for an infant with a birth weight of 3 kg.
ANS: B
Girls seem to be more advanced in physiological growth at all ages than boys. There does not appear to be a relation to growth during infancy.
ANS: D
The most accurate measure of skeletal age is radiological examinations of the growth plates. These are the epiphyseal cartilage plates. Radiographs of the hand and wrist provide the most useful screening to determine skeletal age. Age of tooth eruption varies considerably in children, so it would not be a good determinant of skeletal age. Assessment of height over time will provide a record of the child’s height, not skeletal age. Facial bone development does not reflect the child’s skeletal age, which is determined by radiographic assessment.
ANS: D
This is the area of active growth. Bone injury at the epiphyseal plate can significantly affect subsequent growth and development. Trauma or infection can result in deformity. The matrix, connective tissue, and calcified cartilage are not areas of active growth. Trauma at these sites will not result in growth problems for the long bones.
ANS: D
Lymph nodes grow rapidly and reach adult size at approximately age 6 years. They continue growing until they reach maximal development at age 10 to 12 years, which is twice their adult size. A rapid decline in lymph node size occurs until they reach adult size by the end of adolescence.
ANS: B
The BMR is the rate of metabolism when the body is at rest. At all ages, the rate is slightly higher in boys than it is in girls. The rate is increased by fever. The BMR is highest in infancy and then is closely related to the proportion of surface area to body mass. As the child grows, the proportion decreases progressively to maturity.
ANS: B
This is a description of a difficult child, who compose about 10% of the population. Negative withdrawal responses are typical of this type of child, who requires a more structured environment. Mood expressions are usually intense and primarily negative. These children exhibit frequent periods of crying and often violent tantrums. Easy children are even-tempered, regular, and predictable in their habits. They are open and adaptable to change. Approximately 40% of children fit this description. Slow-to-warm-up children typically react negatively and with mild intensity to new stimuli and adapt slowly with repeated contact. Approximately 10% of children fit this description. Fast-to-warm-up children is not one of the categories identified by Chess and Thomas.
ANS: B
Industry is the developmental task of school-age children. By age 12 years children engage in tasks that they can carry through to completion. They learn to compete and cooperate with others, and they learn rules. Identity versus role confusion is the developmental task of adolescence. Integrity and intimacy are not developmental tasks of childhood.
ANS: D
According to Piaget, a child this age is in the preoperational stage of development. Children interpret objects and events not in terms of their general properties but in terms of their own relationships to them. This egocentrism does not allow children in this age group to put themselves in another’s place. Selfishness, self-centredness, and preferring to play alone do not describe the concept of egocentricity.
ANS: A
Object permanence is the realization that items that leave the visual field still exist. When the infant searches for the toy under the blanket, it is an indication that she has developed a sense of object permanence. Returning blocks to the same spot on a table is not an example of object permanence. Recognizing a ball of clay is the same when flat is an example of conservation, which occurs during the concrete operations stage from 7 to 11 years of age. Banging cubes together is a simple repetitive activity characteristic of developing a sense of cause and effect
ANS: B
Preoperational thinking is concrete and tangible. Children in this stage of development cannot reason beyond the observable, and they lack the ability to make deductions or generalizations. Increasingly logical thought, inductive reasoning, and the ability to make generalizations are characteristic of the concrete operations stage of development that takes place from 7 to 11 years of age.
ANS: C
During the concrete operations stage of development, which occurs approximately between the ages of 7 and 11 years, increasingly logical and coherent thought processes occur. This is characterized by the child’s ability to classify, sort, order, and organize facts to use in problem-solving. The progression from reflex activity to imitative behaviour is characteristic of the sensorimotor stage of development. The inability to put oneself in another’s place is characteristic of the preoperational stage of development. The ability to think in abstract terms and draw logical conclusions is characteristic of the formal operations stage of development.
ANS: D
Preschoolers are most likely to exhibit characteristics of Kohlberg’s preconventional level of moral development. During this stage they are culturally oriented to labels of good or bad, right or wrong. Children integrate these concepts based on the physical or pleasurable consequences of their actions. Obeying rules of correct behaviour, showing respect for authority, and knowing behaviour that pleases others are characteristic of Kohlberg’s conventional level of moral development.
ANS: A
Toddlerhood is a time of imitative behaviour. Children will copy the behaviour of others without comprehending that the activities have any significance or meaning. During the school-age period, most children develop a strong interest in religion. They accept the existence of a deity, and petitions to an omnipotent being are important. Although adolescents become more skeptical and uncertain about religious beliefs, they do understand the significance of religious rituals
ANS: D
A toddler playing with sand and water is engaging in sense-pleasure play. This type of play is characterized by nonsocial situations in which the child is stimulated by objects in the environment. Infants engage in skill play when they persistently demonstrate and exercise newly acquired abilities. Dramatic play, where children pretend and fantasize, is the predominant form of play in the preschool period. Social-affective play is one of the first types of play infants engage in, by responding to interactions with people.
ANS: C
In associative play, no group goal is present, and each child acts according to his or her own wishes. Although the children may be involved in similar activities, no organization, division of labour, leadership assignment, or mutual goal exists. Solitary play describes children playing alone with toys different from those used by other children in the same area. Parallel play describes children playing independently while among other children. Cooperative play describes children in a group who engage in organized activities with a common goal.
ANS: B
An example of parallel play is when both children are engaged in similar activities in proximity to each other; however, they are each engaged in their own play, such as Brian and Kristina playing with their own trucks side by side. Sharing clay is characteristic of associative play. A group of children playing a board game is characteristic of cooperative play. Playing alone on the mother’s lap is an example of solitary play.
ANS: D
Using a board game requires cooperative play. The children must be able to play in a group and carry out the formal game. In solitary, parallel, and associative play, children do not play in a group with a common goal.
ANS: D
Sensorimotor activity is a major component of play at all ages. Active play is essential for muscle development and allows children to release surplus energy. Through sensorimotor play, children explore their physical world by using tactile, auditory, visual, and kinesthetic stimulation. Creativity, socialization, and intellectual development are each functions of play that are major components at different ages.
ANS: B
Parents should be alert to notices of toys found to be defective and recalled by manufacturers. Children do not have the ability to determine the safety of a toy, this is the adult’s responsibility.
ANS: A
Nutrition is the single most important influence on growth. Dietary factors regulate growth at all stages of development, and their effects are exerted in numerous and complex ways. Adequate nutrition is closely related to good health throughout life. Heredity, culture, and environment all contribute to the child’s growth and development; however, good nutrition is essential throughout the lifespan to maintain optimal health.
ANS: C
Children respond to everyday stresses by trying to change the circumstances or adjusting to the circumstances the way they are. An inappropriate response is for parents to solve their child’s problems. Learning problem-solving skills, listening to music, and using relaxation techniques are positive coping strategies for children.
