HOW Can We Study The Mind?
• Metaphor: Mind is a “Black Box”– Can observe what it does, how it responds,
but can’t see it
• Approaches– Self-report– Find a way to open it– Study how it behaves
• Example: How long does it take to respond to different stimuli?

WHAT Determines Behavior?
1. Mind or Body?

1. Mind or Body ?
• Roots of modern psychology lie in the disciplines of philosophy and biology
• Descartes: Two Separate entities– Mind controls body through pineal gland– If so: impossible to scientifically study the mind.
• Psychologists today: One and the same– Mind arises from brain activity– “The mind is what the brain does” – Steven Pinker

2. Nature or Nurture ?
• To what degree are we shaped by innate/inherited tendencies, environment?
• NATURE: – Babies are born with a set mental structure, know
certain things- Natural selection for certain adaptive traits (Darwin)
• NURTURE:– We are shaped by our environment– That is, our personal experiences
![Page 20: 1 SCIENTIFIC STUDY OF PSYCHOLOGY: Theory & Research](https://reader033.vdocuments.mx/reader033/viewer/2022050802/56649e425503460f94b35014/html5/thumbnails/20.jpg)

The Modern View:Nature + Nurture
• Most characteristics do have a genetic (inherited) component– Examples: personality, intelligence
• Experience shapes how these traits develop– Example: educational experiences, traumatic
experiences
• both matter; both necessary
