Gender Identity

Gender Identity is defined by, Encyclopedia Britannica “as an individual’s self-conception as being male or female, as distinguished from actual biological sex.” A person can identify the concept of being a male or female through their psychological alertness. As early as 18 months a child can identify one’s anatomic sex. Gender is always a debated issue in today’s society. Some people argue that gender is solely based on biological makeup (nature), or based on the environment and social interactions one was brought up in (nurture). In this paper, I will explain the interaction between hormones and behavior and how these interactions affect the determination of gender identity. From a biological factor (nature), gender is decided during fertilization. There is 23 pair of chromosomes that determines the sex of a fetus. Within the eggs of females, they only contain the X chromosome, although within the sperm of males it contains either an X or Y chromosome. The X and Y chromosomes in the male sperm are called sex chromosomes that determine the gender. In the womb, it is said that the all embryo start out as the same sex that all embryos have feminine looking genitalia. When the X chromosome of a male sperms reaches the X chromosomes of a female egg, the process of zygote takes places which, produce a combination of XX meaning the embryo is a female. When the Y chromosome of a male, reaches the X chromosome of the female egg in a process of zygote, it produces a combination of XY meaning the embryo is a male. However, in many cases there have been arguments that biological factors do not determine gender. There are times when gender cannot be determined in being male or female because one may be born with either a female and male genital or organs (hermaphrodite). Hormonal influences play a major part in gender identification both…...

Psy 355 Week 3 Paper

...Week 3 Paper PSY 355 Dr. Brenya Bucholski Week 3 Paper The human organism is amazing and its complexity goes beyond the tangible body itself. The cognitive functions are so fascinating to consider; the ability to emote, reason, and make decisions have drawn many into the search for a better understanding of the mind. The mind-body dualism theory is a theory that argues that the mind, also referred to as the soul, and the body are distinct from each other. This is highly regarded in many religions, such as Hinduism, that believes in reincarnation. Reincarnation requires the mind to be independent of the body and free to flow from one body to another in life after life. As psychology continues to develop as a science and with the advancements in scientific technology it brings to question how our psyche functions within this organism. Consider motivation. Does the body, specifically the brain, operate our motivation? I want to look into the motivation to exercise. What are the functions taking place that will drive a person to make the decision to exercise? Is this a function of the mind, the body, or a combination of both? Maslow’s Hierarchy of Needs is a great model to illustrate the interactive nature of our mind and body. It is also a good flow chart to point out some differences between intrinsic and extrinsic motivations. In psychology, the terms intrinsic and extrinsic motivation are common. Intrinsic motivation is essentially the personal satisfaction of an......

...Research Methods To determine how one would analyze research methods for uncovering basic emotions, one must first understand what the basic emotions consist. Deckers stated, “Psychologists have classified emotions into basic categories” (2010, p. 315). The three basic theories of human emotions are category analysis evolution theory and facial expressions. The evolutionary theory and facial expressions theory will be discussed. Evolutionary Theory Evolutionary. Within the research method of evolution theory, is how emotions influence human and animal survival. This theory identifies eight emotions that correlate to functions required for the continued survival of the species in question. For instance, an emotion of one’s fear aids protection of a species as it provokes running to safety, thus promoting survival. Within the evolution theory these eight emotions, which are crucial for survival, include reproduction, incorporation, orientation, reintegration, fear, destruction, exploration, and rejection (Deckers, 2010). Another example is in some young animals have a response, which makes them freeze. This response is triggered by fear if the animal feels threatened by predators. The animal will immediately stop all movement and freeze in place making it harder for a predator to track their movements (Deckers, 2010). This type of behavior is also seen in humans threatened by danger, some will become almost catatonic in a state of shock unable to move talk or follow......

...Sources of Motivation xxxxxxxxxxxx PSY/355 Jxxxx 9, xxxxx xxxxxxxx, Ph.D. Motivation is the drive that moves an individual into action. Motivation comes from several sources such as biological, psychological or external. Motivation affects behavior in many ways. This essay will define motivation, identify the sources of motivation, describe the relationship between motivation and behavior, and explain how behavior displays motivation. According to “Collins Dictionary of Sociology” (2006) the description of motivation is emotional, such as love, or it may involve the cognitive appraisal of a situation”. Motivation is a psychological and biological urge or impulse that enables an individual to act towards a desired goal, intention, or course of activity. It is goal based behavior that is the catalyst or reason for an action or change of action. The sources of motivation can be biological, psychological or external. The biological component of motivation is associated with the physical needs of the body and mind that stimulate behavior such as hunger, thirst, sleep, sex or pain. One example of this is physiological and chemical changes in hormones that signal hunger. The more this signal increases, the more one is impelled to do something that will relieve the feeling of hunger. Psychological aspects of motivation can be measured by the use of scales and questionnaires that measure......

Defining Motivation

...Defining Motivation PSY/355 February 11, 2013 Gavin G. Coriell, M.S. Ed What is motivation? Motivation is what drives one to do something. Motivation is how one is able to achieve a goal, a task, desire, or necessary action to obtain a reward, incentive, or a self gratification. Motivation is a behavior that drives someone to perform an action or strives to change an action. Motivation is individually based as each individual has different desires, motives, and incentives as to what motivates them into their personal goals, personal needs and self-gratification. Human’s motivation is determined as a behavior in which one has to perform a certain behavior to receive a result in either the terms of a goal, an accomplishment or a necessary need. If one is hungry they get up and get something to eat; if one hears music they find catchy they begin to bob their head or sing with music/song lyrics or even hum to the notes. The motivations in these two examples are the motivation to eat to satisfy hunger. The motivation for bobbing the head, singing or humming to music is the satisfaction of enjoyment or the encouragement to dance a feeling of pleasure associated with the behavior of motivation. In motivation there are several sources in which motivation initiates from. Right now there are 20 students taking this class; Motivational Process in Human Psychology the goal or achievement is to obtain a Bachelors Degree in Psychology, however the reasons for......

...Motivation PSY/355 Sources of Motivation Motivation can be one of two influences, internal or external. It makes an individual move in a particular direction or take action. There are either positive or negative motivations, which cause positive or negative effects. A positive motivation is pleasurable or rewarding effect on someone, where negative motivation can lead to something painful. Being positively motivated can be many things mainly it is makes an individual feel good. An example of positive motivation would be parents telling their kids that if they get good grades they would let them pick the next family trip. An example of a negative motivation would be criticized by your boss about your work while they aren’t doing anything would make you do less work and not respond well to them. Biological and psychological motives are two sources of motivation. Biological needs motivate humans to behave a certain way. The most important biological needs are hunger, thirst and human connections to others, which motivates humans to seek and find food and water. Both food and water are important to human survival. For example the need for comfort for an individual who is too hot or cold will change t the temperature in the room. Psychological needs are the motivation to belong in groups in society. The psychological need to be happy can also include the need to make others happy. A student goes to class and is psychologically motivated......

The Emotions of Us

...The Emotions of Us Team B August 5, 2014 University of Phoenix PSY/355 One very popular method for uncovering basic emotions is through facial expressions. From the moment we are born we demonstrate emotion through facial expressions. In babies, it is very important that they are able to demonstrate their feelings through facial expressions. There are many different kinds of emotions that every human being experiences during certain situations. Some emotions would be anger, sadness, fear, happiness, love, surprise, anxiety, amongst many others. Facial expressions make it very simple to be able to notice what kind of emotion the individual is going through. Babies are unable to communicate by speech or bodily gestures when they are born or in their first years of life, therefore it is very important for people to be able to associate the baby’s facial expression to their emotion. When a baby is sad they will make a certain facial expression letting the parents know something is wrong. Same goes if the baby was in pain, hungry, or tired. Because kids and adults are able to speak and communicate both through speech and body language, it might make it seem as if facial expressions were no longer needed to know how someone is feeling, but in research it is still very important. For example, a doctor would be able to tell if his patient is in pain or afraid even if they do not want to let the doctor know something is wrong just by the patient’s facial expression.

...Running head: Motivation 1 Motivation PSY-355 February 3, 2014 Paul Knoll Motivation 2 Motivation Everything a person does is driven by some type of motive. Deckers (2010) states that motivation is to be moved into action, or to decide on a change in action. Motivation directs a person toward their goals. For example a person returning to school is motivated to earn a degree so they are qualified for a better career. There are many reasons behind someone returning to school and the reasons they go and keep them motivated are different. A person’s behavior and emotions are affected by motivation. People who run marathons run them for different reasons some run for health, some for fun and some to raise money for a cause. Whatever the reason the person running is being motivated for one reason or another to finish the race. A person who finds out they have a health issues may be motivated to change their outlook on life as a whole. They may start eating better and exercising more. This is where the push and pull metaphor comes in. A person is pushed to eat but they are pulled in the direction to make the right choices in the food they eat. Tosca Reno (2008) stated “necessity is the mother of all invention it’s true, but fear can be a wonderful motivator as well.” This person was scared of their health issues and made the changes for the better because they were driven by fear. Deckers (2010) states the word emotion is like the......

Motivation

...Motivation Carlos Aguinaga PSY/355 September 09, 2013 Henry Hernandez Motivation Motivation plays a large role in just about all aspects of life, from wanting to get up and workout to wanting to sit down and finish schoolwork. The proper motivation can inspire people to do their best and the lack of motivation can keep people from doing their job to their full potential. Motivation defined Merriam-Webster defines Motivation as the act or process of giving someone a reason for doing something: the act or process of motivating someone (Merriam-Webster, 2013). So motivation is something that a person feels makes them want to get in motion to accomplish certain tasks by using different sources to spark interest. A motivation is the “process by which a person is moved into action. Motivation can originate from internal sources, described as biological and psychological variables, and from external sources, such as incentives and goals” (Deckers, 2010, Pg. 1). Motivation Sources There are internal and external sources to what motivates people. Internal sources state that it is who or what the person is that will determine their motivating factors. “A persons biological attributes and psychological dispositions determine what will be motivating” (Deckers, 2010, Pg. 8). The biological variable refers to what the body needs in order to survive. For example, if your brain tells you that you are hungry that will usually motivate someone......

...Sources of Motivation Paper Kellie Dahl PSY/355 March 30, 2015 Tracy Christian-Cruz Sources of Motivation Paper “I think I can, I think I can” this common phrase is usually heard when trying to get motivation flowing. This is just one small part of motivation and where it comes from. By defining motivation, learning where it comes from, how it relates to behavior, and how behavior can affect motivation, one can learn to be at the “I think I can” step of being motivated. Motivation is, by definition; the act or instance of motivating, the desire to do; interest or drive (Collins English Dictionary, 10th ed.). This definition is very broad and can be interpreted in many ways. To break it down lets look at the act of being motivated, which is said to be moving into action or deciding on a change in action according to the philosopher Arthur Schopenhauer (1841-1960). He believed that actions were not spontaneous in nature but were induced by motives or incentives (Deckers, 2010). A motive is a person’s internal disposition to be concerned with and approach positive incentives and avoid negative incentives, while an incentive is the anticipated reward or adverse event available within the environment. These two are linked because receiving an incentive is the goal of a motive (Deckers, 2010). One good example commonly used to describe this is being hungry; hunger is the motive for getting something to eat. Since our motivation comes from events that move us......

Motivation and Brain

...Motivation and the Brain Paper Due: April 29, 2013 Psy/355 Motivation and the Brain Paper Certain nutrients have been found in scientific literature to support the structural and functional health of the brain, and the nessessary componets in protecting against brain related diseases like Alzheimer's and Parkinson's (Hall, 2011). Several parts of the brain initiates, and maintains motivation that engages in healthy eating. Some researchers say that evolutionary factors come into play. Factors like reinforcements of endorphins and serotonin activity producing the fullness and well-being feelings after eating (Stone, 2011). If one tries denying these reinforcing experiences, this causes difficulty maintaining a stablized diet. According to Psychological musings, factors such as biological, and enviornmental influences help in the implecation of new, and specific behavior like maintaining a healthy diet (Stone, 2011). To maintain continual motivation in healthy eating there are many brain structures that do contribute. Brain structures that maintain the motivation for healthy eating are the limbic system, hypothalamus, hippocampus, and the amygdala. These structures together form new memories, regulate emotions that maintain positive attitudes about considered diet changes (Stone, 2011). The limbic system is linked with reward, and motivation. This system has a very important role in healthy eating. This allows the...

Motivation and the Brain

...The Brain and Motivation Motivation to Stop Smoking Christina Cheshire Emeka Wolfe-Norman, Ed.S, LPC PSY/ 355 February 27, 2012 Most drugs, including nicotine, induce a “euphoric” effect in the mind (Lewis, 2009) that can be difficult to “undo.” Smoking for most will be the most difficult thing they will ever do. I know that I have a personal interest in this paper. I am a smoker who is trying to quit. I have been a smoker for over fifteen years and I have come to a point in my life where I know that I must stop and it is a daily struggle but also achieveable. Structures of the Brain and Smoking According to Lewis (2009), “nicotine is known to activate neuronal nicotinic receptors in the mesolimbic dopamine system.” What this means is that nicotine acts as a neural transmitter of sorts, and activates the dopamine system, creating the euphoric or calming effect most often associated with cigarette smoking. Because these receptors become sensitive to nicotine use, a person will become accustomed to the hypersensitive psychomotor activation (Lewis, 2009). The psychomotor activation creates a sense of alertness, boots metabolism,...

Motivation and the Brain

...Motivation and the Brain PSY/355 September 9, 2013 University of Phoenix Motivation and the Brain Motivation is involved in every area of a person’s life. When a person eats healthy, exercises, quits smoking, stops drinking, goes to school, goes to work, and many other thing he or she does through the power of motivation. Motivation gives a person a reason to act: the act of giving somebody a reason or incentive to do something. The brain is the where motivation begins. The brain is our control center for the functioning and development of human beings. The driving force in motivation is the brain, it also controls actions needed for him or her to become motivated about something. To stay on an exercise routine requires motivation, but that motivation is sometimes blocked by our internal struggles. The limbic system and hypothalamus has been linked to contributing to motivation of exercising. It also takes intrinsic and extrinsic factors to help a person stay motivated to exercise. The different brain structures as well as intrinsic and extrinsic factors work together to motivate someone to exercise. Increases in motivation can lead to changes in the brain, this involves the limbic system and hypothalamus. These changes extend their influences to other parts of the brain and to the rest of the body through the endocrine system (AKRI Ltd. Applied knowledge research and innovation, 2013). This system uses chemical messengers that can have a measurable......

Social Influences on Behavior

...Running head: Social Influences on Behavior Social Influences on Behavior University of Phoenix PSY / 300 Date: Instructor: Social Influences on Behavior There are a number of characteristic changes that occur in the intellectual, moral and physical development of the adolescent. During this time, the individual moves from a structured, relatively undemanding environment into the more complex and blurred world of adult society. This transition is accomplished by most individuals with some difficulty, but ultimately with success. However, some individuals have great difficulty in making the required adaptations to move from childhood through their adolescence and into adulthood. Social researchers have been focusing on identifying those factors that put youth at risk for development issues. Adolescence is, by its very nature, a high risk time for all young people. This is because it is a time of such great change. This period is relatively chaotic for young people putting them at greater risk for the development of problem behaviors and habits. (TAP, 2007). Different types of social environments encourage the development of different behaviors. There are five levels of the model addressing the systems of adolescence. Each of the systems is dissimilar from the others. These systems involve all manner of social influences. Family, school, peers, neighbors, friends, religious influences, media and cultural norms all help to define the individual’s......

...Arousal, Behavior, Stress, and Affect Paper Lauretha Morris PSY 355 January 24, 2012 It is necessary to understand the difference between physiological and psychological needs due to the changing in our environment. There is a close behavior pattern between the brain structure and motivation behavior that is very helpful in understanding the habits which are formed to be unhealthy to individuals. Maslow’s hierarchy of needs postulates that the needs of a person are organized into an ascending structure, going from lower physiological needs to the needs of safety, belongingness, esteem, and self- actualization (Deckers, 2005). The difference between physiological and psychological needs is that physiological is physical and it tends to deal with our thought processes and the way that the brain works. A cognitive neuroscience and focuses on the branch of biology dealing with functions and the activities of living organisms and their parts which include all the physical and chemical processes are what physiological psychology is known as. Something such as a drug, a physiological reaction would often refer to how the body physically reacts. Organisms, organ systems, organs, cell and bio molecules carry...
