Sigmund Freud constructed his psychosexual theory

on the basis of his adult patients’ memories of painful childhood events.

id is the source of basic biological needs and desires.

Freud’s psychosexual theory was eventually criticized because

it overemphasized the influence of sexual feelings in development.

In contrast to Sigmund Freud, Erik Erikson

One reason that the psychoanalytic perspective is no longer in the mainstream of child development is because

rigorous research methods.

The information-processing approach

is better at analyzing thinking into its components than at putting them back together into a comprehensive theory.

the clinical method

Professor Martinez wants to know if children who receive one-on-one instruction at school feel more self-confident than children who receive group instruction. To identify a causal relationship between type of instruction and self-confidence, Professor Martinez should
