Psych - Sensations and Perception

How many sense for AP psychology

8

Iconic sense

occipital lobe - our sense of sight

Echoic Sense

temporal lobe - our sense of hearing

Olfactory sense 

temporal - our sense of smell

Gustatory Sense

frontal lobe - our sense of taste

Skins senses

parietal lobe - sense of touch

Vestibular Sense

Parietal Lobe - Sense of Balance

Kinesthetic Sense 

Frontal - sense of movement

Pain sense

parietal lobe - sense of pain

Sensation

is our brain processing external stimulation and information from our 8 senses

Perception

Sensation plus meaning, our experiences change our perception

Bottom-up Processing

observing the particulars, parts, and sensations first, and that observable impacts our interpretations

Top-down Processing

starting with the concept, the whole, or perception, behavior is impacted by previous experience

Signal Detection Theory

Absolute Threshold and Difference Threshold

Absolute Threshold

the threshold of stimulus required to detect the stimulus half of the time

Feature Detectors

different parts of our brain working together for recognition 

Perceptual Constancy 

size, shape, and color are perceived to remain constant even when stimulus is changing 

Difference Threshold (JND)

just noticeable difference - smallest amount of change in stimulus you notice half of the time 

Weber’s Law 

more likely to notice the just noticeable difference when stimulus is low, less likely to notice it when stimulus is strong 

Fast Neural Path way

sensory input to thalamus to amygdala, in all animals, thinking in terms of survival and is autonomic

Slow Neurual Pathway

Sensory Input to Thalamus to Cerebral Cortex to Amygdala, only in humans thinking more somatic, humans constantly fighting between fast and slow pathways

Slow pathway is slower because

1. Extra stop

2. processing in cerebral cortex takes time

3. It is just a slower path

Selective Attention

ability to focus on certain stimulus when there are many

Emotional Intelligence

how we control the display of our emotions, how we control the fast pathway
