Key words for my psych quiz
| Question | Answer |
|---|---|
| Cortex Specialization | The idea that different parts of the brain perform different tasks and are associated with different parts of the body |
| Broca's Aphasias | problems with fluency in speech production due to damage |
| Occipital Lobe | back of the head, above the cerebellum receives information from visual fields of opposite eye |
| Temporal Lobe | Above the ears, includes auditory areas, each receiving input form the opposite ear |
| Parietal lobe | Top of the head receives sensory input of touch sensation (Pain, pressure, temp) |
| Somatosensory cortex | Specified area of the parietal lobe that takes in sensory input form corresponding body parts |
| Frontal Lobe | Behind your forehead, largest lobe |
| Prefrontal Cortex | controls executive functions that allow us to think, solve problems, and make decisions |
| Motor Cortex | sends signals to our body |
| Circadian Rhythm | Our biological crack that regulates our mood, temperature, and arousal through a 24 hour cycle |
| Activation Synthesis Theory | Limbic system becomes active as were in (REM) and randomly fires, cerebral cortex is trying to interpret random electrical activity we have while sleeping |
| Sensation | The process by which our sensory receptors and Nervous system receive and represent stimulus energies from our environment |
| Difference Threshold | Note the minimum difference between two stimuli required for detection 50% of the time |
| Weber's Law | To be perceived as different two stimuli must differ by a constant percentage rather than a constant amount |
| Sensory Adaption | Is diminished sensitivity as a consequence of constant stimulation or exposure |
| Sensory Interaction | when one sense influence another |
| Synesthesia | Where sensory stimulation triggers more than one sense |
| Retina | The light sensitive inner surface of the eye with layers of neurons |
| Blind spot | An area of perception of understanding that an individual is unaware of |
| Optic Nerve | Where neural impulses are carried from the accommodation |
| Lens | Transparent structure which changes shape to focus images on the retina |
| Accommodation | The process of focusing images from the retina |
| Nearsightedness | Those who see things up close, but struggle seeing things from far away |
| Farsightedness | Those who can see from far away but struggle to see things up close |
| Fovea | The central focal point in the retina around which the eyes cones cluster where visual activity is the greatest |
| Transduction | Process of converting one form of energy to another or converting sensory stimulation into neural signals |
| Rods | Retinal receptors that detect black, white and gray, are sensitive to movement and are necessary for peripheral vision |
| Cones | Retinal receptors concentrated near the center of the retina responsible for daylight color vison |
| Trichromatic Theory | Explains how humans perceive color through retina responsible for daylight color vision |
| opponent process theory | states that color vision depends on three sets of opposing retinal processes |
| Prosopagnosia | A neurological disorder characterized by the inability to recognized |
| Ganglion Cells | Final output neurons of the retina which collects the electrical messages concerning the visual signal from the two layers of nerve cells procedding it. |
| Blindsight | A condition in which a person can respond to a visual stimulus without consciously experiencing it |
| Amplitude | Magnitude or intensity of a stimulus or response |
| Place theory | The pitch of a sound we hear is due to activation of specific har cells on the basilar membrane |
| Volley Theory | Groups of neurons can work together to perceive sound at frequencies beyond their individual firing rates |
| Frequency Theory | Basilar membrane vibrates in response to sound, and the speed of vibration |
| Conduction hearing loss | Inability to hear due to damage to mechanical elements of the ear |
| Sensorineural hearing loss | Inability to hear due to damage to the cochlea's receptor cells or to the auditory nerves |
| olfaction | our sense of smell, also a chemical sense and works closely with taste |
| pheromones | Chemical signals, usually by smell, that influence behavior of other members of same species |
| Gustation | Our sense of taste, a chemical sense with a identified taste sensations |
| Taste receptors | Specialized cells located on the sate buds of the tongue and other areas of the oral cavity |
| Umami | Middle of the tongue |
| Oleogustus | To describe a specific taste sensation associated with the perception of fat |
| Gate control theory | Spinal cord acts as a buffer between pain and the brain, deciding which signals will pass through |
| Vestibular Sense | Monitors the head and body position, as well as our sense of balance |
| Kinesthetic sense | The sense of our individual body parts position and movement |
| Semicircular Sense | Structures in the inner ear that play a crucial role in balance and spatial orientation |
