Studies involving participants . and. “INFORMATION ABSENT”. SCENARIOS. We present three types of stimuli consisting of words, phrases, or pictures on a computer screen. Target stimuli are things that we know the suspect knows, whether he/she committed the crime or not. We make sure he/she knows these things before the test. Since he/she recognizes the targets as significant in this context, his brain emits an “Aha!” response. This is called a P300-MERMER (memory and encoding related multifaceted electroencephalographic response). It has a positive followed by a negative voltage at the midline parietal area (middle of the top of the head near the back). It looks like a peak followed by a valley in the red line.. sensory adaptation. Absolute Thresholds. The . minimum. stimulation needed to detect a particular stimulus 50% of the time.

Exploring the Line Between Personal Quirks and Functional Impairments. by Jenny Lujan, OTR. Definition of Sensory Processing. Sensory processing refers to the ability to take information from our senses (touch, movement, smell, taste, vision, and hearing) and put it together with prior information, memories, and knowledge stored in the brain to make a meaningful response. .
