But, when this same person is asked to pick out an object using only the LEFT hand, this person will correctly pick out the spoon. This is because touch information from the left hand crosses over to the right hemisphere - the side that "saw" the spoon.
However, if the person is again asked what the object is, even when it is in the person's hand, the person will NOT be able to say what it is because the right hemisphere cannot "talk. In this figure, the dominznt on the left is a woman and the face on the right is a man. Therefore, if the patient focuses on the dot in the middle of the forehead, the visual information about the woman's face will go to the right cerebral hemisphere and information about the man's face will go to the left hemisphere.
When a split brain patient is asked to point to a whole, normal picture of tali face that was just seen, the patient will usually pick out the woman's picture remember, the information about the woman's face went to the RIGHT cerebral hemisphere. However, if the patient is required to say whether the picture was a man or a woman, the patient will SAY that the picture was of a man. Therefore, depending on what the patient is required to do, either the right or left hemisphere dominant talk dominate.
In this case, when speech is not required, the right hemisphere will dominate for recognition of faces.
Before different types of brain surgery, it is important to identify which cerebral hemisphere is dominant for language so that the neurosurgeon can avoid damaging speech areas. One way to test which hemisphere is dominant for language is with a procedure called the Wada Test.
During this test, a fast acting anesthetic called sodium amytal amobarbital is injected into the right or left carotid artery. The right artery dominat the right cerebral hemisphere and the left artery supplies the left cerebral hemisphere. Therefore, either the right or left hemisphere can be "put to sleep" temporarily.
If the left hemisphere is put to sleep in people who have language ability in the left hemisphere, then when asked to speak, they cannot. However, if the right hemisphere is put to sleep, then these people will be able to speak and answer dominnat. Remember too that because the right hemisphere controls muscles on the left side, people will not be able to move the left side of their bodies.
Though an interrupter in the same sex group was seen more dominant than the male in the cross sex group, it was only for the first two interruptions. Also, for the first section of vominant survey with two interruptions, in the same conversation but not the second or third sections it was found that the female interrupter, compared to a male interrupter, was seen as more dominant in a cross sex dyad. Vocal control, loudnessand pitch also have been found to be associated with dominance.
Dunbar and Burgoon had partners and third party observers rate dominance after participating or observing an interaction. Couples were initially separated and asked to write a list of dominant talk they would like to spend a hypothetical gift of money on. The couple was then reunited and then asked to tly domminant the top things their money talj be spent on.
Participants rated their partners' dominance after the interaction while third party observers tall their perceptions during the interaction.
They found that observers rated males and females more yalk when they expressed higher vocal control. In an additional experimentTusling used participants and divided them into three groups. Group one watched and listened to a video across various influence goals, while group two was given a transcript of the messages and group three watched the video without sounds.
Each group gauged dominance levels using a Likert scale from He found that amplitude, a measure of loudness, and amplitude variation, an indicator of change dictated perceptions of dominance. It was also found that frequency, a measure of pitch, and frequency variations were reliable predictors of dominance.
Verbosity, speech rate, and message length were all found to be reliable predictors of dominance. The increased amount of words used in an interaction or verbosity was linked to more dominant perceptions by observers for males. Tussling and Dillard found that slower speech rates were found to predict increased dominance perceptions.
Shorter messages were also found to predict dominance. Nonverbal indicators[ edit ] Nonverbal communication indicators are most readily located on the face such as Visual Dominance Ratio  and indicators expressed through the hands such as adaptor and illustrator gestures  have been linked to dominance. An individual's body can indicate dominance as well through posture, elevation, relaxation  and body lean. Facial indicators such as expressivenessvisual dominance ratio, and gaze, and as well were all found to relate to dominance.
dominabt In terms of expressiveness, males, but not females, were rated as more dominant when they were facially expressive. In addition, Carney, Hall, and LeBeau found that more facial expressiveness was appropriate for those with more power and that these individuals were also more likely to have self-assured expressions. The eyes also have something to doinant in terms of dominance. Dunbar and Burgoon found that higher visual dominance ratios were correlated with higher perceived dominance for males and females.
Dominant talk, Carney, Hall, and LeBeau found that more glaringmore mutual gaze, longer gazing, and more looking while speaking would be more appropriate coming from an individual with more power. Emotions are readily expressed by individuals making it easier to identify expressions of dominance.
Hareli and Shomrat looked at various approach, neutral, and avoidance emotions. They ran two studies in order to understand perceptions of emotions as they related to dominance. Both studies asked participants to gauge levels of dominance.
In study one, individuals rated pictures of men and women with different emotions expressed. In study two, 96 individuals watched a male technician fail at his job and then explain himself showing a neutral, angry or shameful expression. Emotions surveyed included approach emotions such as anger and happinessneutral emotions and inhibitive or dominanh emotions such as shamefear or sadness. Approach emotions are rated as the most dominant when compared to inhibitory emotions Carney, Hall, and LeBeau, ; Hareli and Shomrat, ; Montepare and Dobish, In contrast, Montepare and Dobish found that dominant talk was perceived as more dominant than anger, while Hareli and Shomrat found the opposite.
Females were perceived as more dominant than males when expressing happiness and males were perceived dominant talk slightly more dominant than females when expressing anger Hareli and Shomrat, Hareli and Shomrat also found interesting as it relates to neutral expressions. For instance, males were seen as ificantly more dominant than females when expressing neutral expressions and neutral expressions were seen about as dominant as angry expressions for men, which is more dominant than inhibitory emotions.
Inhibitory or avoidance emotions were seen as the least dominant Carney, Hall, and LeBeau. Sadness as opposed to fear was seen as the least dominant Hareli and Shomrat, ; Montepare and Dobish, Females expressing fear or sadness were seen as less dominant than males expressing the taok emotion Carney, Hall, and LeBeau.
Sadness and fear were also seen as more fitting for an individual with lower power Carney, Hall, and LeBeau, Hareli and Shomrat found that shame tended to decrease perceptions of dominance more so than anger increases perceptions of dominance for males. For females anger was perceived as the most dominant emotion followed by happiness, then a neutral expression, then fear and least dominant of all sadness.
In comparison, anger was perceived as the most dominant expression for males, closely followed by a neutral expression, then happiness, then fear and least dominant of all sadness.
Furthermore, body control, posture, lean, and openness all were found to relate to dominance. For instance, Dunbar and Burgoon found that the more body control a woman had the more observers perceived her as dominant.
Carney, Hall, and LeBeau found high power individuals were perceived to lean forward, have open body positions, orient towards the other, and have an erect body posture more so than those of less power.
