Bret Haynes well, I first took it in 1994 in a downloaded program from a bbs and loved it enough to get it done at at local college, same result (Infp) Then I experimented with the at home one more. 3rd time I came up as intp — then a month later back to Infp. That’s when I realized that the difference in some answers is slight Actors have to change their apparent personality, and we all do to some degree for the most part We can even suspend our personalities and allow another personality to project itself upon us We do that on a regular basis watching a movie, becoming the character temporarily.

ah ha! terms for things i was interested in. 10ms range “The term auditory brainstem response refers to the responses recorded from the brainstem, usually in the first 10 msec after stimulation” looks like i have to look into “Neuroanesthesia” as that’s the area where “it’s all brainstem”. https://www.sciencedirect.com/book/9780323059084/cottrell-and-youngs-neuroanesthesia

It’s a 50ms range “automated control” of ignoring repeated sound. It’s used to measure “attention span”. But it can be excessive or diminished. I think mine may be diminished, which means less ability to ignore repeated stimulus – and ability to ignore plays a huge part in “paying attention”. I looked and found: “Reduced P50 auditory sensory gating response in professional musicians” (shown) and “Diminished Infant P50 Sensory Gating Predicts Increased 40-Month-Old Attention and Anxiety/Depression Symptoms” and “Long-term deficits of preterm birth: Evidence for arousal and attentional disturbances” a) I’ve been ‘musical’ since I was in the high chair apparently (a music teacher wanted me to go to Julliard, giving me special lessons and I almost went but I turned it down – and glad I did) and b) was diagnosed with generalized anxiety at 11 and realized a couple of years ago that I fit adult ADHD to a T *and* c) was preterm (29/30 weeks I think?). So, a possible tie-in for several personal mysteries. This doesn’t mean that I _wouldn’t_ have been musical if I wasn’t pre-term – there’s simply no way to know – but it’s intriguing. https://pubmed.ncbi.nlm.nih.gov/16524657/

ah yes, right range. “We used the P50 midlatencyauditory evoked potential, which has been used extensively to measure pre-attentionalmechanisms and is mediated by brainstem-thalamus processes (Buchwald et al. 1991; Garcia-Rill and Skinner 2001). This waveform occurs from 45–75 milliseconds after an auditorystimulus and is usually paired with a second auditory stimulus.”
ah yes, right range.

I got here by looking into time perception, finding out “rats without brains” can learn and remember up to 40 second intervals, then seeing “reticular formation” with regards to consciousness. Some answers I’m looking for may be here in particular. My next goal is here: “Long-term deficits of preterm birth: Evidence for arousal and attentional disturbances” —- There are several potential factors that may adversely influence the development of the ascending reticular activating system: Preterm birth: Regardless of birth weight or weeks of gestation, premature birth induces persistent deleterious effects on pre-attentional (arousal and sleep-wake abnormalities), attentional (reaction time and sensory gating), and cortical mechanisms throughout development. https://en.wikipedia.org/wiki/Reticular_formation

An intact brainstem is essential for all vegetative functions e.g. autonomic regulation of respiration, heart rate, blood pressure. A hypothalamus and pituitary gland are necessary for ingestive, social and sexual behaviors, homeostasis, endocrinology, salt and water balance, body temperature, and circadian rhythms. Motor ctx, basal ganglia, and thalamus are necessary for goal directed movement. The hippocampus is needed for memory. The primary sensory modalities, smell, visual, hearing and touch are needed to sense the external world. In the case of rodents and many other species, olfaction is essential. Between the behavioral testing, MRI, and post mortem histology, it was possible to observe many of these functions, and confirm their location and organization in R222. The transformation of cortical mantle was the most dramatic change in R222 as compared to age matched controls, particularly the visual and auditory cortices. How did R222 see and hear? In a review on the functional organization of the vertebrate brain, Merker makes a compelling argument for the upper brainstem e.g., thalamus, hypothalamus, midbrain DA system, superior/inferior colliculi, and pons for the integration of sensory information needed for goal directed behavior in real time. All these areas have access to somatosensory, visual and auditory information independent of the cortex. Long before encephalization there was centralization of function in the upper brainstem for sensory integration, learning, memory, motivation, and organization and expression of complex behaviors. This centralization of life functions in subcortical areas would include the olfactory bulbs and cerebellum as noted above. R222 lived a long “normal” life by defaulting to brain organization that has sustained and propagated vertebrate life since inception.”

Under “Time Perception” in Wikipedia, I read: “Experiments have shown that rats can successfully estimate a time interval of approximately 40 seconds, despite having their cortex entirely removed. This suggests that time estimation may be a low level process”
