Week 6 Quiz

At home, a toddler on a parent's lap is looking at a farm picture book. The toddler knows the family dog well and points to a cow on the page, saying "Doggie!" In Piaget's terms, which process does calling the cow "doggie" show?

Select one.

• Assimilation: the cow is fitted into a scheme the toddler has
• Accommodation: the toddler's scheme changes so that it fits the cow
• Deferred imitation: the toddler copies a word heard much earlier
• Object permanence: the toddler knows the dog still exists at home

Record R2 of the running case (illustrative): at 9 months, in the family home with a parent present, the infant finds a toy twice under the left cloth, watches it hidden under the right cloth, then searches under the left cloth again. Which reading fits Piaget's account and Dataset D?

Select one.

• No object permanence at all, since the search under the left cloth failed
• The A-not-B error, from the fourth substage, at about 8 to 12 months
• The typical fifth-substage response, which Piaget placed at about 12 to 18 months
• A preoperational response, because the infant is still too young to search

In Dataset D, Piaget's fifth sensorimotor substage, in which the typical response on the A-not-B task is to search under B, runs from about 12 to 18 months. How many months wide is that approximate window?

Select one.

• 4 months
• 30 months
• 6 months
• 18 months

At an illustrative family barbecue, a 17-month-old watches a grandparent flip burgers with a spatula. The next day, with the grandparent gone home, the toddler takes a toy spatula and flips a block on a play stove. Which concept does this behavior show?

Select one.

• Babbling, because the toddler is practicing the sounds of a language
• Assimilation of the spatula into a sucking scheme from early infancy
• The A-not-B error, because the toddler repeats an action from yesterday
• Deferred imitation: an action copied after a delay, model absent

Record R3 of the running case (illustrative): at 14 months, at a childcare center's morning drop-off, the toddler says "ball", "up", and "more". Which description fits these three words?

Select one.

• Expressive language: single words, no two-word combination yet
• Receptive language, because the toddler understands what a caregiver says
• Babbling, because each of the words is only a single syllable long
• Two-word combinations, because the toddler says more than one word

In the typical sequence of early language, two-word combinations usually come before babbling.

True or false.

• True
• False

The CDC revised its "Learn the Signs. Act Early." milestone checklists in 2022. On a revised checklist, what does each listed milestone describe?

Select one.

• What the average child, half of all children, does by that age
• What every child must do by that age to avoid a delay
• What most children, 75 percent or more, do by that age
• The age at which a health professional diagnoses a delay

In an illustrative bilingual household, a parent speaks one language with a baby and a grandparent speaks another. A neighbor worries that two languages will slow the baby's talking. Which statement fits what this course teaches?

Select one.

• Bilingual exposure delays language, so the family should choose only one language
• They reach early milestones only if neither language is the language of the home
• Judge the baby by the word count in the stronger language alone, as the fair measure
• Counted together, both languages show early milestones on a typical timeline

Researchers who measure how long infants look at possible and impossible events report that infants understand some properties of objects earlier than Piaget's search tasks showed. How does this course read that work in relation to Piaget's theory?

Select one.

• As a refutation that replaces Piaget's theory entirely
• As a refinement of Piaget's account, not a refutation
• As proof that infants are passive until they can reach
• As evidence that object permanence appears all at once at birth

A classmate writes, "Piaget's stages are a fixed timetable, so every baby enters the fourth sensorimotor substage on reaching 8 months." Which statement about Piaget's stage model fits this course?

Select one.

• The names and order are fixed; the ages are approximate
• Both the stage names and their ages are fixed deadlines
• The ages are fixed, but the stages may come in any order
• Neither the names nor their order matter, only the ages
