Psychology Chapter 1-3, 14 Unit Test #1
| Question | Answer |
|---|---|
| Sensation | When sensory information is detected by sensory receptors |
| Transduction | The conversion from sensory stimulus energy to action potential (relaying messages) |
| Absolute Threshold | The minimum amount of stimulus energy that must be present for the stimulus to be detected 50% of the time. |
| Subliminal Messages | Messages that are presented below the threshold for conscious awareness (we receive it but are not consciously aware of it) |
| Just Noticeable Difference (JND) | How much difference in stimuli is required to detect a difference between them. (changes depending on the stimulus intensity) |
| Perception | The way sensory information is organized, interpreted, and consciously experienced. |
| Bottom-up processing | The sensory information occurring from your environment (the server at a restaurant dropping a tray and creating noise) |
| Top-down processing | The sensory information that occurs from previous experience or knowledge (misplacing your keys and looking for the yellow key fob, you would check for logical places, and for bright yellow. |
| Sensory adaption | When your senses get used to the environment one way or another, like smells or noises |
| Inattentional blindness | The failure to notice something that is completely visible because the person was actively attending to something else and did not pay attention to other things |
| Signal detection theory | The ability to identify a stimulus when it is embedded in a distracting background (a mother hearing her baby at night) |
| Wave amplitude | The distance from the center line to the top point of the crest or the bottom point of the trough. (decibels from 0-150) |
| Wavelength | The distance of a wave from the top of one crest to another |
| Frequency | The number of waves that pass a given point in a given time period and is often expressed in terms of hertz (Hz), or cycles per second. (longer=lower shorter=higher |
| Visable spectrum | A small portion of the electromagnetic spectrum that we can see |
| Pitch | Associated with the sound's frequency to determine the "volume" (High frequency=high pitch Low frequency= low pitch |
| At what range is there the potential for hearing damage in decibels? | 80-130 decibels |
| Timbre | A sound’s purity, and it is affected by the complex interplay of frequency, amplitude, and timing of sound waves. |
