PSY 100 Lecture Notes - Lecture 21: Multisensory Integration, Infrasound, Body Party
Document Summary
Sound waves: frequency (measured in hz) = pitch. Human voice is around 2,000-4,000 hz: human range = 20-20,000 hz. May be experienced as vibration rather than sound: elephant infrasound. How is this similar to the human ear: amplitude = volume. Amplitude and hearing loss: loudness is measured in decibels (db) The higher on this thermometer, the quicker damage can occur. Hearing tests: deafness: cannot hear speech at less than 82 db. Normal human speech is around 60 db: hearing impairment: any loss in auditory sensitivity relative to the hearing ability of the average, normal young adult. Neural plasticity: watch: the rubber hand illusion. The amount of pain you can handle before you break down (i. e. , physically or emotionally: pain threshold. Trying to tell us to stop doing something so we don"t hurt ourselves further: watch: 12-year-old girl cannot feel pain due to genetic disorder, biopsychosocial model. What would this look like: empathetic pain.
