First, some questions for your notes:

What is the ideal ageWhat is the ideal ageand why?and why?

What is the worst ageWhat is the worst ageto be, and why?to be, and why?

Market Facts, Inc. asked these questions of more than1000 adults…

Most respondents, regardless of their actual age, saidthey feel and act as if they are in their mid-thirties.Both men and women wanted to be about 32 years old.

“Psychological age,” suggested the pollsters, “may bejust as important as real age when trying to understandpeople’s behavior and such things as their buyingdecisions.” The sexes differed, however, on the agethey considered to be “old.” Men thought old ageoccurred in the late sixties, and women said old agebegan in one’s seventies.

More recently, a Harris poll asked 2306 Americanadults the following questions: “If you could stop timeand live forever in good health at a particular age,what age would it be?”

In this poll, responses varied with the age group. For18- to 24-year-olds, it was 27. For 25- to 29-year-olds,the age selected was 31. For 30- to 39-year-olds, theanswer was 37. For 40- to 49-year-olds, the responsewas 40. For 50- to 64-year olds, the age was 44; forthose 65 and older, it was 59.

Now, how do your answers compare???Now, how do your answers compare???

Prenatal Development and the Newborn

How, over time, did we come to be who we are? From zygote to birth, development progresses in an orderly, though fragile,

sequence.

ConceptionA single sperm cell (male) penetrates the

outer coating of the egg (female) and fuses to form one fertilized cell.

Prenatal Development

A zygote is a fertilized egg with 100 cells that become increasingly diverse. At

about 14 days the zygote turns into an embryo (a and b). L

The Competent Newborn

Infants are born with reflexes that

aid in survival, including the

rooting reflex which helps them

locate food.


Offspring cries are important signals for parents to provide nourishment. In animals

and humans such cries are quickly attended to and relieved.

To study cognition in newborns, developmental psychologists use the

concept of habituation, or decreasing responsiveness with repeated

stimulation.As infants gain familiarity with repeated

exposure to a visual stimulus, their interest wanes and they look away

sooner.
