aslow's Characteristics of Self-Actualizers A self-actualizer is a person who is living creatively and fully using his or her potentials. In his studies, Maslow found that self-actualizers share similarities. Whether famous or unknown, educated or not, rich or poor, self-actualizers tend to fit the following profile.[12] Efficient perceptions of reality. Self-actualizers are able to judge situations correctly and honestly. They are very sensitive to the fake and dishonest. Comfortable acceptance of self, others, nature. Self-actualizers accept their own human nature with all its flaws. The shortcomings of others and the contradictions of the human condition are accepted with humor and tolerance. Spontaneity. Maslow's subjects extended their creativity into everyday activities. Actualizers tend to be unusually alive, engaged, and spontaneous. Task centering. Most of Maslow's subjects had a mission to fulfill in life or some task or problem outside of themselves to pursue. Humanitarians such as Albert Schweitzer and Mother Teresa represent this quality. Autonomy. Self-actualizers are free from reliance on external authorities or other people. They tend to be resourceful and independent. Continued freshness of appreciation. The self-actualizer seems to constantly renew appreciation of life's basic goods. A sunset or a flower will be experienced as intensely time after time as it was at first. There is an "innocence of vision", like that of an artist or child. Fellowship with humanity. Maslow's subjects felt a deep identification with others and the human situation in general. Profound interpersonal relationships. The interpersonal relationships of self-actualizer

Fellowship with humanity. Maslow's subjects felt a deep identification with others and the human situation in general. Profound interpersonal relationships. The interpersonal relationships of self-actualizers are marked by deep loving bonds. Comfort with solitude. Despite their satisfying relationships with others, self-actualizing persons value solitude and are comfortable being alone. [13] Non-hostile sense of humor. This refers to the wonderful capacity to laugh at oneself. It also describes the kind of humor a man like Abraham Lincoln had. Lincoln probably never made a joke that hurt anybody. His wry comments were gentle proddings of human shortcomings. Peak experiences. All of Maslow's subjects reported the frequent occurrence of peak experiences (temporary moments of self-actualization). These occasions were marked by feelings of ecstasy, harmony, and deep meaning. Self-actualizers reported feeling at one with the universe, stronger and calmer than ever before, filled with light, beautiful and good, and so forth. In summary, self-actualizers feel safe, not anxious, accepted, loved, loving, and alive. Additionally, Schott discussed in connection with transpersonal business studies.

Broader criticism from within humanistic psychology of the concept of self-actualization includes the danger that 'emphasis on the actualizing tendency...can lead to a highly positive view of the human being but one which is strangely non-relational'.[20] According to Fritz Perls there is also the risk of confusing "self-actualizing and self-image actualizing...the curse of the ideal."[21] By conflating "the virtue of self-actualization and the reality of self-actualization,"[22] the latter becomes merely another measuring rod for the "topdog"

I have received a fair number of letters saying 'I am a self-actualized person'. Maslow said that he must have left something out. Fritz (Perls) put it in. He saw that most people actualized a self-concept. This is not self-actualizing."[24]

Normally, when adenosine levels reach a certain point in your brain and spinal cord, your body will start nudging you toward sleep, or at least taking it easy. There are actually a few different adenosine receptors throughout the body, but the one caffeine seems to interact with most directly is the A1 receptor.

it functions as a supremely talented adenosine impersonator. It heads right for the adenosine receptors in your system and, because of its similarities to adenosine, it's accepted by your body as the real thing and gets into the receptors.

caffeine actually binds to those receptors in efficient fashion, but doesn't activate them—they're plugged up by caffeine's unique shape and chemical makeup. With those receptors blocked, the brain's own stimulants, dopamine and glutamate, can do their work more freely—"Like taking the chaperones out of a high school dance,"

caffeine very clearly doesn't press the "gas" on your brain, and that it only blocks a "primary" brake. There are other compounds and receptors that have an effect on what your energy levels feel like—GABA, for example—but caffeine is a crude way of preventing your brain from bringing things to a halt. "You can," Braun writes, "get wired only to the extent that your natural excitatory neurotransmitters support it." In other words, you can't use caffeine to completely wipe out an entire week's worth of very late nights of studying, but you can use it to make yourself feel less bogged down by sleepy feelings in the morning.

What's important to take away is that caffeine is not as simple in effect as a direct stimulant, such as amphet

amines or cocaine; its effect on your alertness is far more subtle.

The general consensus on caffeine studies shows that it can enhance work output, but mainly in certain types of work. For tired people who are doing work that's relatively straightforward, that doesn't require lots of subtle or abstract thinking, coffee has been shown to help increase output and quality. Caffeine has also been seen to improve memory creation and retention when it comes to "declarative memory," the kind students use to remember lists or answers to exam questions.

The effectiveness of caffeine varies significantly from person to person, due to genetics and other factors in play. The average half-life of caffeine—that is, how long it takes for half of an ingested dose to wear off—is about five to six hours in a human body. Women taking oral birth control require about twice as long to process caffeine. Women between the ovulation and beginning of menstruation see a similar, if less severe, extended half-life. For regular smokers, caffeine takes half as long to process—which, in some ways, explains why smokers often drink more coffee and feel more agitated and anxious, because they're unaware of how their bodies work without cigarettes.

regular caffeine use has also been shown to decrease receptors for norepinephrine, a hormone akin to adrenaline, along with serotonin, a mood enhancer. At the same time, your body can see a 65 percent increase in receptors for GABA, a compound that does many things, including regulate muscle tone and neuron firing. Some studies have also seen changes in different adenosine receptors when caffeine becomes a regular thing.

A 1995 study suggests that humans become tolerant to their daily dose of caffeine—whether a single soda or a serious espresso habit—somewhere between a week and 12 days. And that tolerance is pretty strong.

You start to feel caffeine withdrawal very quickly, anywhere from 12 to 24 hours after your last use. That's a big part of why that first cup or can in the morning is so important—it's staving off the early effects of withdrawal. The reasons for the withdrawal are the same as with any substance dependency: your brain was used to operating one way with caffeine, and now it's suddenly working under completely different circumstances, but all those receptor changes are still in place. Headaches are the nearly universal effect of cutting off caffeine, but depression, fatigue, lethargy, irritability, nausea, and vomiting can be part of your cut-off, too, along with more specific issues, like eye muscle spasms. Generally, though, you'll be over it in around 10 days—again, depending on your own physiology and other factors.

Beyond the equivalent of four cups of coffee in your system at once, caffeine isn't giving you much more boost—in fact, at around the ten-cup level, you're probably less alert than non-drinkers.
