Human Growth and Development / Unit 1 HGD 0051 short lesson, about 20 seconds
Theories and Hypotheses
Captions available
The idea
A theory is a well-developed explanation; a hypothesis is a testable prediction drawn from it, often stated in if-then form.
In practice
If attachment shapes later relationships, then secure infants should form closer friendships later.
Where people slip
Research supports, modifies or rejects theories; it never proves them. Science cycles between deductive testing and inductive observation.
