Human behavior

Rewards, such as praise and approval from parents, act as positive reinforcers of specific learned behaviours, while punishments decrease the likelihood of repeating such behaviours.

So a male prefers female mate with blonde hair because he can more easily see how healthy their offspring will be. Well, from an evolutionary standpoint it makes sense to scratch at anything that might be dangerous.

For example, the Wright Brothers ' invention of the first practical fixed-wing aircraft. If an infant is shown a rattle and hears its distinctive sound and the room is then darkened, the infant will reach for the rattle if the sound indicates that the object can be grasped but will not reach if the sound indicates that it is beyond his grasp.

These fundamental features of living depend on the entire brain, yet… Theories of development The systematic study of children is less than years old, and the vast majority of its research has been published since the mids. As young infants, they show high levels of motor activity and fretfulness in response to stimulation.

By 18 months, with exposure to stairs, the average child can walk up and down them without help, and by his second birthday he can run, walk backward, and pick up an object from the floor without falling down. He will also turn his head toward a touch on the corner of his mouth or on his cheek; this reflex helps him contact the nipple so he can nurse.

Judging from their facial expressions when different substances are placed on their tongues, newborn infants apparently discriminate between bitter, salty, or sweet tastes ; they have an innate preference for sweet tastes and even prefer a sucrose solution to milk. The use of meaningful words differs from simple babbling in that speech primarily helps to obtain goals, rather than simply reflecting excitement.

Technically, another person—at least according to your brain. Children who show only moderate distress when the mother leaves, seek her upon her return, and are easily comforted by her are assumed to be securely attached. He sought help and it was soon discovered that the man had a tumor the size of an egg growing in his brain, pressing on his prefrontal cortex, which as previously discussed regulates urges.

Moreover, it is through the reciprocal interactions between child and parent that infants learn that their behaviour can affect the behaviour of others in consistent and predictable ways and that others can be counted on to respond when signaled. Most babies begin crawling i. When an alert newborn is placed in a dark room, he opens his eyes and looks around for edges.

This explains why laughing is contagious, and tests have shown that humans are far less likely to laugh when alone. The four stages given by Piaget are 1 the sensorimotor stage from birth to 2 years, 2 the preoperational stage from 2 to 7 years, 3 the concrete-operational stage from 7 to 12 years, and 4 the stage of formal operations that characterizes the adolescent and the adult.

The sex organs, along with muscle and cartilage, also have begun to form. Melatonin levels will stay fairly high for roughly 12 hours before exposure to light the next morning causes them to decrease.

And very high on the list of fears we humans have is the fear of "Speaking in public. There have been studies where participants inhale either oxytocin or a placebo and engage in group games with incentives to cooperate.

Finally, infants begin displaying signs of the emotion of fear by their fourth to sixth month; a fearful response to novelty—i. Scientists have discovered a gene they call RS3which is colloquially becoming known as the divorce gene.

A child with libido fixated at one of these stages would in adulthood show specific neurotic symptoms, such as anxiety. This discrepancy principle operates in other sensory modalities as well.

A fourth pattern, characterized by increased movement of the arms and legs, smiling, and excited babbling, occurs in response to moderately familiar events or social interaction and may be termed excitement.

Such behaviour has been observed in children raised in relatively impersonal institutional surroundings and is shared by monkeys reared in isolation. A third set of reactions includes decreased muscle tone and closing of the eyes after feeding, which may be termed relaxation.

Melatonin is a natural hormone that helps us sleep. As young infants, they show high levels of motor activity and fretfulness in response to stimulation. Most importantly, shame and guilt have a large impact on behavior.

Environmental influences ordinarily do not begin to influence vocalization seriously before two months of age; in fact, during the first two months of postnatal life, the vocalizations of deaf children born to deaf parents are indistinguishable from those of infants born to hearing parents.

During their first month, infants sleep for about 16—18 hours a day, with five or six sleep periods alternating with a like number of shorter episodes of wakefulness. The four-month-old infant is also capable of rapidly learning to anticipate where a particular event will occur.

Of course, females seek out and avoid the same qualities in males, so perhaps the adage should be that everyone prefers blondes. He will grasp a finger or other object that is placed in his palm.

Human Behavior!. Human behavior psychology is a very complex topic, no matter how you try to discuss it or even attempt an explanation of how and why we function the way we do!

® One Little Indian Records Ltd. May 29,  · Do genes make us do it? The idea that human behavior is driven by genes makes many people uncomfortable, and nowhere is the dispute more bitter than when discussing the biological underpinnings of violence.

Evolution and Human Behavior is an interdisciplinary journal, presenting research reports and theory in which evolutionary perspectives are brought to bear on the study of human behavior.

It is primarily a scientific journal, but submissions from scholars in the humanities are also encouraged.

Compared with most animals, we humans engage in a host of behaviors that are destructive to our own kind and to ourselves. We lie, cheat and steal, carve ornamentations into our own bodies, stress. What is the study of human behavior - makomamoa.com
