Transduction:

Changing physical energy to neural energy

the senses:

• sight

• hearing

• smell

• taste

• touch (pain)

• touch (temp)

• passive touch (someone tapping you on shoulder)

• active touch (actively exploring with touching)

• proprioception (sensing your body position— i know where my nose is without having to see it or feel where it is)

• introception (info about our own body’s internal state — heartrate, internal temp, respiration, etc…)

• vestibular system (balance and posture)

who is known as the founder/godfather of ecological psyc?

JJ gibson

what did jj gibson say?

our senses are our info gathering and they help us behave and survive and be able to pass on our genes to our offspring (natural selection)

known for affordances (think pen to us and pen to an ant)

what were jj gibson’s 5 senses?

1. basic orienting

2. auditory

3. haptic (touch)

4. taste-smell

5. visual

what are the three approaches to the study of perception?

• psychological

• biological

• theoretical

what are the two categories of the psychological approach to the study of perception?

• phenomenal/naturalistic: relies on subjective experiences (theres limits because we can’t use this on animals or babies and since it’s subjective, my experience may be way diff from someone elses, also hard to describe (think dude ranches)

• experimental: do this—> get that. manipulate this variable—> see change in this variable. (dr. seeing how small yoiu can see words on the wall— objective). cons: not very real world— too controlled

what are the two categories of the biological approach to the study of perception?

• lesion technique: cutting into brain to see how it effects whatever were looking at. cons: not humane, could effect other parts of the brain we don’t want to

• Brain scans: PET, MRI, evoked potentials, etc…

what is the category of the theoretical approach to the study of perception?

• anaologies: tyring to link eperiences to make themm make sense to ourselves (camera to eye or computer to brain)

absolute threshold:

the y-intercept. the minimum amount of stumulation we need for detection (what’s the minimum thing you can percieve)
