PSYCH ASSESSMENT Flashcards
Goodluck on your Psych Assessment!!! GANBARE!!!
Receiving message about the world.
Sensation
enables s to see, hear, taste, smell, touch, balance, and experience such as feeling of
body stiffness, soreness, fullness, warmth, pleasure, pain, and movement. Operate
through the sensory receptor cells.
Sense Organ
is any aspect of the outside world that directly influences our behavior of conscious
experience.
Stimulus
the process converting stimuli into codes of electrochemical impulse that the neurons
can carry and the brain understands.
Transduction
the smallest magnitude that can be detected
Absolute Threshold
the smallest difference between two stimuli that subjects can detect half the time
Difference Threshold
weakened magnitude of a sensation resulting from a prolonged presentation of the
stimulus.
Sensory Adaptation
The receptor organ:
The Eye
The Receptor Cells
Photoreceptors (rodes and cones)
Stimulus in Vision
Light (Electromagnetic energy)
the transparent bulge at the front of the eye where light enters
Cornea
the white opaque outer wall of the eye
Sclera
clear fluid that fills the front chamber of the eye
Aqueous Humor
an opening surrounded by the iris through which light passes into the eye
Pupil
the pigmented muscular curtain near the front of the eye, between the cornea and the lens, that is perforated by an opening called the _____
Iris
a thin layer of tissue that lines the back of the eye on the inside
Retina
the _______ _____ connects the eye to the brain
Optic Nerve
the visual dimension seen as a particular color; determined by the length of a light wave
Hue
the intensity of color; determined by the height of a light wave as such that the higher the wave, the greater the amplitude, and the brighter the color
Brightness
the bulging and flattering of the lens in order to focus an image on the retina
Accomodations
Receptors in the retina that are most sensitive in dim light; do not respond to color.
Rods
Receptors in the retina to color and fine detail.
Cones
Visual adjustment that increases the sensitivity of the rods and cones and allows us to see better in dim light
Dark Adaptation
The visual adjustment of the rods and cones that reduces sensitivity to bright light
Light Adaptation
Nearsightedness (Vision Problem)
Myopia
Farsightedness (Vision Problem)
Hyperopia
Night-blindedness (Vision Problem)
Nyctalopia
Farsightedness at old age (Vision Problem)
Presbyopia
Increased pressure within the eyeball (Vision Problem)
Glaucoma
A disorder in which the lens becomes cloudy (Vision Problem)
Cataract
The eye is the correct shape. The light rays focus on the retina. (Near and Far sighted)
Normal Eye
The eye is too long. The light rays focus in front of the retina. (Blurry at a distance) (Near and Far sighted)
Nearsighted Eyes
The eye is too short. The light rays focus behind the retina. (Blurry close up) (Near and Far sighted)
Farsighted Eyes
Caused by defective cones in the retina of the eye and as a more general term.
Color blindness ( more accurate term: Color deficient Vision)
People either have no cones or have cones that are not working at all.
Monochrome color blindness
Essentially, if they have cones, they only have one type and, therefore, everything looks the same to the brain
Shades of Gray
Are caused by the same kind of problem-having one cones that does not work properly.
Dichromatic Vision
Due to lack of functioning red cones.
Protanopia
Results from the lack of functioning green cones.
Deuteranopia
By Doctor Shinobu Ishihara
Color Blind Test (1917)
Only with good color vision people can see the sign; color blind individuals will not be able to see it (Different Designs)
Vanishing Design
Color blind people will see different sign than people color vision handicap (Different Design)
Transforming Design
Only color blind people can spot the sign (Different Design)
Hidden Digit Design
This is used to differentiate between red and green blindness (Different Design)
Classification Design
Receptor organ: (Hearing)
The Ear
Receptor cells: (Hearing)
