AP Psych Unit 3 Review

the process by which our sensory receptors and nervous system receive and represent stimulus energies from our environment.

• Sensation
• Perception
• Consciousness
• Cognition

the process of organizing and interpreting sensory information, enabling us to recognize meaningful objects and events. – the process by which your brain organizes and interprets sensory input

• Perception
• Consciousness
• Sensation
• Cognition

Starts at the sensory receptors and works up to higher levels of processing

• bottom-up processing
• parallel processing
• lateral processing
• top-down processing

Constructs perceptions from the sensory input by drawing on our experience and expectations

• Top-down processing

• intuition
• bottom-up processing

• interpretation

the focusing of the conscious awareness on a particular stimulus

• selective attention

• ignorance
• distraction
• concentration

failing to see visible objects when our attention is directed elsewhere

• perceptual blindness
• selective attention
• visual impairment
• inattentional blindness

failing to notice changes in the environment

• change blindness

• neglecting the environment
• overlooking the surroundings
• ignoring the surroundings

The conversion of one form of energy into another.

• transduction

• Energy transformation
• Energy transfer
• Energy conservation

the study of relationships between the physical characteristics of stimuli, such as their intensity, and our psychological experience of them.

• Psychoanalysis
• Psychophysics
• Psychometrics
• Physiology

minimum stimulation needed to detect a particular stimulus 50% of the time

• sensory adaptation
• absolute threshold
• difference threshold
• perceptual set
