- Level of consciousness: changes in the intensity or degree of consciousness
- Is it all or none? Graded in intensity, in breadth, or both?
- Remember that even if we can answer these questions we still won’t know about the
quality/content of the person’s experience. What does less consciousness feel like (e.g.
is pain more intense as complex experiences reduce?)
-
- Deep sleep, coma → lose consciousness

- Can we be more conscious? → through arousal or super intelligent
- Can we be less conscious? → when we are tired

- More conscious → general person would say I was more alive → standing on a cliff, just
walked up a hill, feel more in the moment; psychedelic ⇒ feel more conscious; linked to
intensity of sensory experience, when people talk about high levels of consciousness ⇒
all sensory stuff; maybe actually are experiencing more, have a greater intensity of
experience; does more conscious mean greater variety (higher contrast or brightness) or
is it the same basic elements you’re experiencing but higher intensity, each experience
is somehow magnified but has all the same features
- Less conscious → while doing taxes?; in exams?; doing complex problems, maths
problems

Document Summary
Level of consciousness: changes in the intensity or degree of consciousness. Remember that even if we can answer these questions we still won"t know about the. Graded in intensity, in breadth, or both? quality/content of the person"s experience. What does less consciousness feel like (e. g. is pain more intense as complex experiences reduce?) Textured thing face or textured thing quickly masked by another texture. The greater the time distance between texture and face, the more likely a person should see it. Young babies: early response, no clear separation, whether conscious or not conscious of stimulus there is no difference. Older babies: at the end start getting separation. Three fastest stimulation times: assumption is babies weren"t conscious of the face, no late response; if had more time then did see late response. Brain response to information as a baby is really slow 300-500ms (adult 100- 15-18 months: slow brain response but more consistent with adults thought response.
