Research Sequence

Theory

Hypothesis

Collect data

Analyze data

Summarize and confirm or modify theory

Theory

Ideas that propose an explaination

hypothesis

testable prediction that gives direction to research

Goals of Modern psychology

1. description

2. explanation

3. prediction (Hypothesis)

Independent variable

controlled by experimenter

Dependent variable

experimenter measures to determine effect of IV

Correlation

Positive and negative

positive- move in same direction (height up, weight up)

negative- move in opposite direction (economy up, Unemployment down)

_______ doesnt imply causation

True experiments

Operational definition

how the researchers define the area of interest

olfaction- smell

tactile- touch

gustation- taste

perception

how we mentally organize and interpret that information

absolute thresholds

bare minimum intensity to detect 50% of the time

difference threshold

bare minimum increase you would detect 50% of the time

subliminal threshold

below threshold, can’t detect

sound waves

frequency

measured in hertz

humans can hear between 20 and 20,000

amplitude

perceptual dimensions

loudness

pitch

localization

timbre-different frequencies of vibrations

Outer ear

pinna and auditory canal

middle ear

ossicles

hammer, anvil, stirrup

inner ear

cochlea

the chemical senses

molecule detectors

oculomotor cues-one eye

convergence

accommodation

binocular/retinal disparity

right eye sees different than left eye

pictorial cues

overlap

size and height in field of view

familiar size

looking through the atmosphere, things further away are harder to see

when in motion things that move fast are close, things that move slow are far away.
