PPT 1 Term one week one Memory-Sensation and Perception

I didnt add stimuli for sensory organs for all of them

What should I know?

Memory, sensation and perception, processes of sensation (reception, transduction, transmission, processes of perception (selection, organisation and interpretation)

Sensation definition

the detection and processing of environmental stimuli by the sense organs and the conversions of sensory information to electrochemical energy

What type of response is the process of sensation and why + example?

A physiological response, because it does not engage the brain. Sensing the environment around us using touch, taste, smell, sight and sound

What is a message out brain receives?

Its from a sensory receptor that has been stimulated.

Process of our brain receiving a message

Stimulus to sensory receptors to electrochemical signal to brain

Name visions stimulus energy, sensory receptors and organs, region of the brain electrochemical energy is registered

Light waves, eye, primary visual cortex (occipital lobes)

Name touch +other skin sensations stimulus energy, sensory receptors and organs, region of the brain electrochemical energy is registered

mechanical and thermal energy, skin, primary sensory cortex (parietal lobe)

Reception definition

the detection of sensory information in the sense organs of the body like ears and eyes.

Transduction definition

the changing of sensory information into electrochemical energy

Electrochemical energy definition

the form of energy that the human nervous system and brain can process

Transmission definition

the movement of electrochemical energy is transferred to the brain for processing

Steps withing sensation

sensation to perception and reception to transduction to transmission

Perception definition

the mental representation that the brain creates using information detected by the senses

What type of process is the process of perception and what does it involve?

The process of perception is a psychological process that involves giving meaning to sensations

Process of perception

selection to organisation to interpretation

selection definition

the brain filters information (stimuli) selecting important information features

organisation definition

selected features of stimuli is categorised to form meaningful patters

interpretation

the brain interprets the whole, giving them meaning based on past experiences which can differ from person to person
