e. Tibia: If the Malleolus points to the right it is a right side bone

In 10 Myths About Psychology, Ben Ambridge discusses many of the myths that are used in psychology. The first common myth is about gender. Many believe that women are better with grammar and men are more intelligent when it comes to reading maps. While this is true the difference between the two genders in each of these subjects is very minimal. However, many believe that there is a dramatic difference. Another interesting myth involves being a right or left brained learner. In school many are led to believe that one side of the brain involves creativity and the other works with equations. Depending on which side of the brain is more active dictates which type of learner a person is. This leads to the assumption that left-handed people

No two people in the world have the same fingerprints and therefore no two people have the same hands. You can tell a lot about a person by their hands. For example, a harding working man may have rough, beaten-up hands. On the other hand, a man with a desk job may have soft, gentle hands. Hands symbolize our own identity and how we see others. After reading the play Macbeth we can tell a lot about Lady Macbeth by her hands. The word hand is used strongly as a symbol for guilt in the Shakespearean play called Macbeth.

When we look at new born baby, most of the time when they explore the new world, they will use their hand try to reach the object that they are interested in. To remember how that object feel through touching. When we grow up, when we meet someone, the first thing we will do is to give out our hand to greet other with a handshake, in fact this simple action can also reveal our personality. When we do not like or trying to protect ourselves, our hand will become a fist, ready to punch to express dislike. In a relationship, we often see couples holding hands, which can also explaining as they are fear to lose each other, besides they are willing to hand their life to their opponent. When we are holing other hands, we feel secure and someone to

2013). Functional lateralization is found to form at an early age, and lateralized connections can be unique amongst individuals (Nielson et al. 2013). Change in lateralization with age is insignificant, defending that lateralization development occurs during the stages of early development (Nielson et al. 2013). Current studies have concluded that lateralization does not vary amongst genders, but instead individuals (Nielson et al. 2013). The question of left or right brain dominant has arisen after Sperry’s contributions. Research has concluded that left or right brain dominance does not exist as a whole, but instead varies amongst individuals (Nielson et al.

Chimps for example, have similar hands to humans, however, when using a hammer stone, they frequently use a power grip where all fingers are used to control nut-cracking (Wong, 2004). Here, their finger proportions inhibit easy coordination between the index finger and thumb (Wong, 2004). This is significantly different to that of hominids who have hands and thumbs which are very effective and allow for precise knapping and control over hammer stones. This illustrates that their differences in physical characteristics lead to distinctly different behaviors that cannot be considered the

The other test held was an auditory test. The test was done in two different ways. One way was finding the objects in a bag that were mentioned verbally and the other was identifying the item reached by touch. This test’s results were also supporting the previous researchers’ logical conclusion about the left hemisphere ability of speech. It confirmed the right hemisphere’s ability of comprehending language and its ability of expressing it in a nonverbal way. During the test, evidently, the right hemisphere had no trouble identifying the unknown objects by touch as the left hemisphere did. Moreover, some three- dimensional drawings of the slit-brain patients, who were all right handed, developed much better drawings using their left hands compared with their right hands.

The hand is a very important extremity attached to the human body and is used in everyday life. Humans use it doing almost everything. The major systems the body uses to be able to move the hands are the skeletal, muscular and nerves systems. The skeletal system of the hand involves the bones, such as, eight carpal bones, five metacarpal and fourteen finger bones (Istitute for Quality & Efficiency in Health Care, 2013). All connected by joints and ligaments. The muscles include two parts, the thenar eminence and the hypothenar eminence (Istitute for Quality & Efficiency in Health Care, 2013). The thenar eminence moves the base of the thumb, also lets the thumb touch the four fingers; the hypothenar eminence allows the little finger to bend

As she tried to overcompensate utilizing her left hand more often than her right hand, she found that her left hand began to experience the same symptoms as her right hand.

The participants for this study were recruited from a Spring 2013 Experimental Psychology Undergraduate Course at Queens College, City University of New York. The research study was IRB approved and the participants for this study were not compensated. However, by remaining in the course, the students gave consent to participate in all studies. There were a total of 22 participants, 20 being females and two males. The participants consisted of 21 right-handed individuals and one left-handed. The mean age was 21.09 years, and the standard deviation for age was 1.02.

Let’s start out with Jacquelyn McBain, an animal and human behavior specialist who commented on a question displayed on a website called Quora. McBain wrote that right handed people tend to turn towards the right while left

Hands can symbolize so many different things. They give a brief glimpse into the soul and feelings of their owner. The position of hands can have several meanings. Imagine

Left-right brain dominance is about the fact that the distinct hemispheres influence thinking. The left hemisphere is associated with logical, analytical thinking and a linear approach to problem solving. The right hemisphere is associated with creative, intuitive and value-based thought process. It is important to note that everyone uses its both hemispheres, but to varying degrees. Four quadrants of the brain, related to different thinking style, have been identified:

Before a person is able to even start to warm up their arms, they must figure out if they do not know yet which arm is their throwing arm and which arm will be for catching. In most cases the hand the person writes with is their dominant hand and will be their throwing hand; however, that is not always the case and it can be switched. Although if it the case the dominant hand will be the had you throw with and the other hand will be the hand the glove is placed on. To create a clear picture if the person throws with their right hand the glove will be placed on the left hand, and if the person is left handed the glove will be worn on the right hand.

32 participants recruited via SONA and word of mouth. For some of the participants was paid £15 or print credits corresponding to the current SONA recommendation for a 2-hour and some of the accepted to take part voluntarily to ERP experiment. 12 females and 20 males took part in an experiment and 29 of them were right-handed and others 4 were left handed. The ages of participants were ranged from 18 to 30 (mean=19.72). One female and one male’s data discarded from the final analysis because of the symmetrical topographies which prevented to determine EEG artifact and unexpected problem data could not segment. The informed consent (see appendix .) is signed and the Edinburgh handiness questionnaire form was filled to determine which hand they use before beginning the experiment and the debriefing form (see appendix .) was signed after the experiment ends which were given approval by the Psychology Ethics and Research Committee (see appendix .). If there is also a case where they are uncomfortable, they could terminate the experiment at any time.
