Question 1

After the first word is spoken, ​

Accepted Answer

Vocabulary growth tends to be slow initially after the first word is spoken, but after several months, it accelerates significantly, leading to a rapid increase in the number of words a child can understand and use.

Question 2

Harlow's research with monkeys raised with two types of artificial mothers found that when frightened, infant monkeys went to the artificial mother that ​

Accepted Answer

Harlow's research demonstrated that the infant monkeys preferred the comfort provided by a soft, cloth-covered mother over the wire mother, even when the wire mother was the one providing food. This highlighted the importance of comfort and tactile stimulation in the development of attachment in primates.

Question 3

Harlow's finding that "contact comfort" is an important factor in forming attachment is LEAST consistent with the views expressed by

Accepted Answer

Behaviorists focus primarily on observable behaviors and the ways in which they are learned through interaction with the environment. Harlow's findings on "contact comfort" emphasize emotional and physical connection as foundational to attachment, which is less aligned with the behaviorist focus on conditioning and reinforcement as the primary mechanisms of learning and development.

Question 4

A child who says, "I sawed a cat in the yard," is making which of the following errors?

Accepted Answer

The child is making an overregularization error by incorrectly applying the regular rule of adding "-ed" to make the past tense of "see," instead of using the irregular past tense "saw."

Question 5

Jenna is 14 months old and uses only "bottle," "no," "up," "bye-bye," "mama," and "dada" when she talks. However, when the family is on their way to visit Jenna's grandm ​ other, and her father tells Jenna to get her blue bunny from the bedroom and bring it with her, Jenna quickly runs to get the bunny. This episode demonstrates that

Accepted Answer

Toddlers like Jenna often understand more words (receptive vocabulary) than they can actually say or use (productive vocabulary), as shown by her ability to follow her father's instructions despite her limited spoken vocabulary.

Question 6

Jasmin takes her one-year-old son, Randy, to visit a day-care center where she plans to enroll him. Randy eagerly explores the playroom, and when his mom leaves the room to fill out some forms, he shows no signs of concern. When Jasmin returns, he shows little interest and continues to play with the toys he has collected. This is the type of interaction you might observe between a child and a parent who

Accepted Answer

Randy's behavior indicates an avoidant attachment relationship, characterized by the child showing indifference toward the caregiver upon their return, as seen in his lack of concern when his mom leaves and minimal interest when she returns.

Question 7

Dean ate ice cream for the first time yesterday. All day today, he has been asking for ice cream. This would be an example of

Accepted Answer

Fast mapping is the process by which children quickly learn a new word after just a few exposures to it. Dean's immediate request for ice cream after trying it for the first time demonstrates this rapid acquisition of vocabulary.

Question 8

Children receiving low-quality day care are especially vulnerable to attachment problems when

Accepted Answer

Children with difficult temperaments are more likely to have attachment problems, especially if they are in low-quality day care.

Question 9

Avoidant attachments seem to be _____ common in German infants and _____ common in Japanese infants than in American infants.

Accepted Answer

Research on attachment styles across different cultures has shown that avoidant attachments are more common in German infants due to cultural norms that encourage independence, and less common in Japanese infants, where cultural norms emphasize interdependence and closeness.

Question 10

The vocabulary spurt typically begins at around _____ months.

Accepted Answer

The vocabulary spurt, a rapid increase in the number of words a child understands and uses, typically begins at around 18 months of age.

Question 11

For the first several months of Jasmine's life, she was unconcerned when her parents left her with a babysitter, but at around 7 months, she began to cry every time this happened. Jasmine is experiencing

Accepted Answer

Jasmine's behavior is typical of separation anxiety, a normal stage of development that usually starts around 6 to 8 months of age when infants begin to understand object permanence and become distressed when separated from their primary caregivers.

Question 12

You are listening to two-year-old Annie as she says "No eat. No like." She is trying to let you know that she is not going to eat her broccoli because she doesn't like it. Annie's communication illustrates the use of ​

Accepted Answer

Annie's communication is an example of telegraphic speech, which is typical of the early stages of child language development. It involves the use of short and simple sentences that include only the most essential words to convey a message, omitting smaller, less critical words, similar to how telegrams were written to save space and cost.

Question 13

Which of the following is the BEST example of overregularization? ​

Accepted Answer

Overregularization occurs when children apply regular grammatical patterns to words that are exceptions to the rule, such as using "eated" instead of "ate." This demonstrates their understanding of past tense rules but not the irregular exceptions.

Question 14

Underextension would be evident if a three-year-old child ​

Accepted Answer

Underextension occurs when a child uses a word too narrowly, applying it to a smaller range of objects or situations than is appropriate.

Question 15

Kailee has learned the word "kitty," but she uses this word when she is referring to cats, bunnies, squirrels, and other small furry animals. Kailee's use of this word illustrates ​

Accepted Answer

Kailee's use of the word "kitty" to refer to various small furry animals, not just cats, is an example of overextension. This is a common language development phenomenon where children apply a word in a broader context than is appropriate.

Question 16

Typically, infants with _____ attachments exhibit little, if any, distress when their mothers leave the room.

Accepted Answer

Infants with avoidant attachments often exhibit little or no distress when their caregiver leaves the room, indicating a tendency to avoid seeking comfort or contact from them.

Question 17

If Beth is a typical infant, she will first show signs of understanding the meaning of familiar words at about _____ months of age.

Accepted Answer

Infants typically begin to show signs of understanding the meaning of familiar words around 6 to 9 months of age. This is when they start to respond to their own names and common words like "no" or "bye-bye," indicating early language comprehension.

Question 18

A child's first words are generally spoken at about _____ months of age.

Accepted Answer

Most children speak their first words between 10 to 13 months of age. This developmental milestone can vary, but this range is generally accepted as typical for initial language acquisition.

Question 19

Separation anxiety typically develops when infants are about _____ months old and peaks at around _____ months.

Accepted Answer

Separation anxiety usually starts when babies are about 6 to 8 months old and reaches its peak in intensity between 14 to 18 months. This period is when infants begin to understand their parents' or caregivers' absence but do not have the concept of time to know if or when they will return.

Question 20

Which of the following tends to enhance children's language development?

Accepted Answer

Parents responding to children's communication efforts encourages interaction and provides feedback, which is crucial for language development.
