Psych Unit 4 Module 16 and 17

The Process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment

• Sensation

• Perception

• Bottom-up Processing

• Top-down Processing

• Selective Attention

the Process of organizing and interpreting sensory information enabling us to recognize meaningful objects and events.

• Sensation

• Perception

• Bottom-up Processing

• Top-down Processing

• Selective Attention

Starting with the sensory input, the brain attempts to understand/make sense.

• Sensation

• Perception

• Bottom-up Processing

• Top-down Processing

• Selective Attention

Guided by experience and high-level processes, we see what we expect to see.

• Sensation

• Bottom-up Processing

• Top-down Processing

• Selective Attention

Our tendency to focus on just a particular stimulus among the many that are being received.

• Transduction

• Absolute Threshold

• Difference Threshold

Failing to see visible objects when our attention or focus is directed elsewhere.

• Cocktail Party Effect

• Inattentional blindness

• Transduction

• Absolute Threshold

• Difference Threshold

conversion of one form of energy, such as light waves, into another form, like neural impulses that our brain can interpret
