How does someone achieve a unified self?
lesantik [10]

Answer:

please mark me as brain list

Explanation:

The unified self is a flawed construct. Experience changes us, even at the core. People change us just by being with us. It doesn't have to be a long term relationship. Our minds may not have the plasticity they once had but we adapt daily to the people around us and, in a slower fashion, tide rather than waves rather than ripples, we the ebb and flow of experience changes the "I think" that creates our values and judgements, which changes the experiences we seek then have which again works on the way we view the world.

A possible reason we are able to change when we are with different types of people is that we have a certain number of roles at our disposal. I've noticed this, on an extreme level, with some coworkers. I wondered how they could change so much when they got to the office. They'd suddenly become very business-like and at first I thought they were play acting. They were, in a sense, but I believe their identity changed when they walked through the office door. They were no longer the guy or girl I'd just ridden to work with, they were such and such part of the hierarchy and their behavior wasn't all a put on, though some of everyone's behavior in every role is, it was who they were then.

It took being asked to take a work related personality test that clued me in. The test results came back. One part of results outlined our scores for introversion/extroversion scores at home and at work. The scale was -50 to +50 where the score determined one's level of introversion (-) or extraversion (+). I scored -33 at home and a +33 at work. The automatic scoring algorithm suggested that it was likely I was under a lot of internal stress because of this. I was. I used to have dry heaves when I transitioned from work to home. That part of the results wasn't the only part rang true though so I took it seriously.

How close the roles we play with different people are to each other might be an indicator of how unified we are. If you were to scale our unification factor from 0 to 1 I would have been considered a 0.33 based on my introversion/extraversion scores, if that was the only score that mattered. More things the behavior than others matters, of course. Perhaps people who are very different in differing situations experience more cognitive dissonance. It would be interesting knowing.

The cochlea contains ___________ which send(s) messages through the auditory nerve to the areas of the brain that are responsibl
Vadim26 [7]
The cochlea contains organ of cortis which send(s) messages through the auditory nerve to the areas of the brain that are responsible for interpreting auditory information. The Organ of cortis contains the hair cells and nerve receptors for hearing. When the hair cells has been stimulated, it will react to specific sound frequencies. However, only certain hair cells will be stimulated based on the pitch of the sound. The signals produced by the hair cells will turn into nerve impulses which will be sent out by the cochlear portion of the auditory nerve into the brain. This auditory nerve will carry the impulses from cochlea into the mid-brain which is the cochlear nucleus. On other brain pathways that end in the auditory cortex of the brain these nerve impulses were carried.

Why is it difficult to fossilize large animals?
Dennis_Churaev [7]

Answer:

The hard parts of organisms, such as bones, shells, and teeth have a better chance of becoming fossils than do softer parts. One reason for this is that scavengers generally do not eat these parts. Hard parts also decay more slowly than soft parts, giving more time for them to be buried.
