Support Us Environmental Awareness Environmental awareness is to understand the fragility of our environment and the importance of its protection. Promoting environmental awareness is an easy way to become an environmental steward and participate in creating a brighter future for our children.
Perceptual speed Verbal comprehension Savant Syndrome is rare, and is characterized by extreme talent in one particular area, such as music, but rather poor cognitive functioning in Dependence of man on the environment other fields.
This condition often involves a form of mental retardation, such as autism. Influence of heredity and environment on intelligence Both heredity and the environment play large roles with regards to one's intellectual capabilities. In addition to genetics, life experiences can also affect one's intelligence scores.
Environmental hardships especially during development can negatively affect one's cognitive abilities e.
Variations in intellectual ability Intelligence is hard to measure; many of the tests administered to quantify intelligence have built-in bias, and have unavoidable confounding factors. For example, sometimes racial groups score differently from each other not because of their race, but because of different incomes and availability to different qualities of education.
The average score on an intelligence test is The lowest end of the spectrum falls below 70 mark. At the high of the scale, there are people who score higher than Consciousness States of consciousness: Drugs, poisons, and head injuries can hinder our ability to be aware.
Alertness depends on our hour cycle. The reticular formation also referred to as reticular activating system, RAS structures of our brainstem control levels of arousal.
Sleep Polysomnography PSG is a test used to test measure physiological processes during sleep. The test includes a series of smaller tests, including: Electrooculogram EOG - measures movements of the eyes during sleep. Electroencephalogram EEG - measures the electrical impulses of the brain, these high frequencies and low amplitudes are known as alpha waves collectively referred to as neural synchrony.
Electromyogram EMG - measures musculoskeletal movements. Stages of sleep Stage 1- This stage of sleep has mainly theta waves that are of low to moderate frequency Hertz. During this stage of non-REM rapid eye movement stage of sleep there are slow eye movements. Stage 2 — There is a decrease in heart rate, respiration, and body temperature.
During stage 2 the EEG measures moderate brainwave activity. This stage of the sleep cycle is defined by the introduction of k-complexes and sleep spindles that blend in among the theta waves.
Stage 3 and 4- this is the stage at which we sleep the deepest, and we transition into slow wave sleep SWS. It is characterized by the presence of delta waves.
Delta waves are low frequency 0. During this stage of sleep there is no eye movement, and growth hormones are secreted. REM rapid eye movement - this is the last stage of sleep, characterized by swift eye movements and the presence of dreams. The brainwaves measured by the EEG are low intensity and erratic frequency, and look like the waves that are observed in someone who is awake.
REM sleep is also characterized by a lack of muscle movement. This type of motionless sleep is called paradoxical sleep. Sleep cycles and changes to sleep cycles One sleep cycle: One cycle takes the average person 90 minutes to complete.

We grow during sleep while we are still developing ; the pituitary gland releases growth hormones. It is thought that our brain is processing the day's events and creating long-term memories.
Sleep and circadian rhythms: The circadian rhythm is a biological process that oscillates throughout a roughly hour period. It is also commonly referred to as a biological clock, and can vary depending on age. Our biological clocks are affected by the amount of light we are exposed to natural and artificial.
Light triggers proteins in our retina to send signals to the pineal gland, which produces melatonin. Melatonin is a hormone that causes us to sleep. If one does not sleep well enough to reach the REM stage, the individual will spend more time in REM the next time they sleep.
This compensation is known as REM rebound According to Sigmund Freud called the "story" of our dreams called manifest content are symbolic of our unconscious ideas, called latent content The Activation-Synthesis Theory states that physiological processes happening in the brain create dreams Sleep-wake disorders Parasomnias are abnormal actions that occur during sleep.
Example of a parasomnia is somnambulism, popularly referred to as "sleep walking", as well as night terrors.The Impact of Man on the Environment Man has had many far-reaching effects on the environment over the years.
Global warming, pollution and the damage to the ozone layer are a few of the major things that can be heard about in the news. Contemporary Environmental Issues SCI Dependence of Man on the Environment Environmental Issues 2.
Over population is one of the contemporary environment issues. Overpopulation is a generally unwanted condition where an organism's numbers exceed the carrying capacity of its habitat.
Mixed farming systems & the environment. MIXED FARMING systems, the largest category of livestock system in the world, cover about billion hectares of land, of which billion hectares are arable rainfed crop land, billion hectares are irrigated crop land and billion hectares are grassland. This is a big topic.
So big of a topic that I just had to refill my coffee to the tip tip top and spilled a little on the way back to my computer. Attention. Selective attention: our ability to focus on something that is going on while other, non-related things are going on around us.
Divided attention: the type of attention we need to use when we are forced to do more than one task at a time. I attended the First Zero Hedge Symposium and Live Fight Club in Marfa, Texas, where I presented the following speech: “Breaking the Alternative Media’s Dependence on the Mainstream Media.” The speech was about 45 minutes long, so the article is lengthy.
