An Investigation of the Effect the Presence of Different Genres of Music Have on Reaction Rate to Visual Stimulus
Aylin Huzmeli IB Biology Mr. Steve 22/2/2012 An Investigation of the Effect the Presence of Different Genres of Music Have on Reaction Rate to Visual Stimulus Background: There are many parts concerning the response to a stimulus. A stimulus is any change in the environment which is detected by a receptor and a response is the change in the organism due to that stimulus. The pathway in which a response occurs is comprised of many parts. First a stimulus is detected by a receptor which transforms the stimuli into a nerve impulse. A sensory neuron will connect the receptor to the central nervous system and the neuron travels along its axon. A motor neuron will than carry the impulse from the central nervous system to an effector (muscles or glands) which causes the response in the organism. The time it takes to react to a stimulus is the reaction rate and includes both the reaction time (involves attention resources and processing information) and the movement time (the time it takes for muscles to move. There are different factors that can affect the reaction rate by influencing the attention of an organism. Research Question: What effect does the presence of different types of music such as heavy metal and classical music have on reaction rate compared to no presence of music? Purpose: to compare the effect of heavy metal and classical music on reaction rate
Psychology - analysing myself.
Final Project: Self Analysis WRITTEN BY: LAKIA MARSHALL INSTRUCTOR: MICHEAL FORD CLASS : PSY 285 I am independent, frank, and very nonchalant. I have picked these three words because I think that they accurately describe my personality. I would say that I am independent because I am able to rely on myself. I have a high sense of pride and really don't like to ask for help because of that I make it a point to make sure that I can do things on my own. I would say that I am frank because I don't like to hide what it is that I am thinking. If I feel it I will say it and pride myself on being the person who says what others want to say but won't. With that said, I am not a trouble maker and don't just go around raining on others parades but I will give you my honest opinion if you ask for it and sometimes when you don't. Finally to describe myself I would say that I am nonchalant. I tend to be very Zen for the most part. I don't bother other people and try my best to treat others the way I would treat myself. I don't like a lot of drama or trouble so I tend to stay to myself to remain stress free. In the terms of whether or not I an independent or interdependent I would say that I am independent. I don't mind being alone or doing things for myself. I personally feel that being self-reliant is a gift and not everyone can be or is that way. I like that fact that I work for my
To what extent does the biological level of analysis explain behaviour?
To what extent does the biological level of analysis explain behaviour? The human species' behaviour is a complex item of study. Researchers spend vast amounts of time and capital to find out more about what defines our own behaviour and us. The environment around us, some researchers claim, play an important role in explaining our own behaviour. Hormones, a chemical produced in our body, also play a factor in strongly influencing our own actions. And yet perhaps our "chemical messengers," otherwise known as neurotransmitters, help us rationalize our own behaviour. All three definitely do affect us, but to what extent does it explain? Can we fully explain our own behaviour with knowledge in these three areas? I firmly think that the biological level of analysis explains behaviour to only a certain extent. Hormones, the environment, and interactions between cognition and physiology impact on how we humans behave in society; yet, there are many certain behaviors that modern research have yet to explain. One example of chemicals that affect our functioning is hormones. Hormones "are another class of chemicals that affect behaviour." (Crane & Hannibal, 2009) They are produced by glands and enter directly into the bloodstream, a difference from neurotransmitters. An example of a hormone is Oxytocin, otherwise known as "the love drug." Oxytocin which is produced by the

This theory, first researched by Norman Triplett in 1898, is called social facilitation. Triplett noticed that bike racers have faster times when racing against others compared to racing alone. He also studied the different performances based on the difficulty of the situation. Social facilitation theories have since
The Learning Perspective
The Learning Perspective History and cultural context: - Origins from the start of the 20th century - A contrast to introspection and psychoanalytical theory - Ivan Pavlov and John B. Watson developed a which emphasized environmental stimuli and behavioural response - It grew in popularity the first fifty years - It became the dominant framework for experimental research. Framework: Key concepts: -Classical conditioning: "the study of learning which involves reflex responses, in which a neutral stimulus comes to elicit an existing reflex response due to learning." -Pavlov found that ringing a bell and then immediately giving the dog some food, the bell came to evoke the same response as the food itself - salvation. -Salvation at the presence of food is a basic neural reflex that requires no learning. -Reflex responses; unconditional responses (a reflexive response produces by a specific stimulus, such as pupil contraction to bright light) -The stimulus which elicits (triggers) an unconditional response (like food)is called an unconditional stimulus; (a stimulus which elicits (triggers) a reflexive (unconditioned) response.) -conditioned refers to learned -the bell = neutral stimulus which normally has an orienting response, (a stimulus which initially produces no specific response other than provoking attention; as conditioning proceeds the neutral stimulus
Examine how one or more factors (biological, cognitive, socio-cultural) influence either one specific anxiety disorder or one specific eating disorder?
Examine how one or more factors (biological, cognitive, socio-cultural) influence either one specific anxiety disorder or one specific eating disorder? ________________ Abnormal psychology is a division of psychology that studies people who are ‘abnormal’ or ‘atypical’ compared to the members of a given society. However, it is essential to note the fact that it is a very vague and ambivalent term, not to mention the fact that our socio-cultural heritage and specific circumstances may affect our perspective upon it. This essay will look as post-traumatic stress disorder (a severe anxiety disorder that can develop after exposure to any event resulting in psychological trauma) and the way factors from the cognitive and socio-cultural levels influence it and its classification. In psychology it is very difficult to correctly identify and classify psychological disorder since the psychiatrist will often have to rely primarily on the patient’s subjective description of the problem, which is the main reason for the criticisms brought to studies in the cognitive level of analysis regarding PTSD. For example, cognitive therapists have noted that PTSD patients tend to feel that they have a lack of control over their lives and that the world is unpredictable. They often experience guilt about the trauma (such as a survivor from the Vietnam War etc). However, conceptions of
Experiment. Are bilingual people more proficient at multitasking between cognitive tasks?
Student Research Project Abstract This study aims to investigate whether bilingualism causes improved cognitive ability to motivate students to learn a second language and become global citizens who have proficient understanding of different cultures and globally significant issues. This is conducted through a cognitive test in which you multitask between simple computer tasks and memorisation. The results suggest a small difference in monolingual and bilingual abilities, with monolinguals being more proficient, yet it was inconclusive as there was difficulty finding enough monolingual participants.[1] This illustrates how most of Australia speaks a second language, either from their cultural background or learning at school. Research question Are bilingual people more proficient at multitasking between cognitive tasks? Background research The world’s understanding of bilingualism has dramatically shifted over the turn of the century. Scientists, teachers and the general public long considered a second language to be an interference to children’s cognitive development. However, recent research has shown that it can have a great impact on your brain, improving cognitive skills unrelated to language and even protecting against dementia in old age.[2] When a bilingual person uses one language, the other is active at the same time. This is called language co-activation.
On what circumstances it is okay to kill?
On what circumstances it is okay to kill? By: Risa Santoso There had been a lot of killing that happened in wars, conflicts and perhaps driven-by-emotion incidents also. However is it really okay to kill someone? What about methods like euthanasia? Is there actually a time when killing is considered acceptable? Most people considered killing as an absolute sin. The bible for example, set standards such as the Ten Commandments for us to follow; "Thou shall not murder". There are though, circumstances in which killing is inevitable. Say if we are in the situation where our love ones are threatened to death and there's no other way to stop that if not killing the murderous criminal. Or, for example, when the matter is for self defense where our own selves are the one who is threatened. By the law of the United States, self-defense murders will not be taken as a real murder. If a person is proven to act on self-defense, there will be no charge or punishment taken. WARS & BOMBARDMENT Some people define killing in wars, for soldiers, as something inevitable and not wrong since they are not able to make a choice otherwise to survive. They justified killing as self-defense and as a morally responsible attacker because of they are counted as having an imminent threat and have no other option to avoid that threat. Even though it is not wrong to kill someone on wars, soldiers,
Evaluate the role that one cultural dimension (e.g. individualism/collectivism, power distance) may have on behaviour.
Evaluate the role that one cultural dimension (e.g. individualism/collectivism, power distance) may have on behaviour. According to Matsumoto (2004), culture can be defined as the common rules that regulate interactions and behaviour in a group as well as a number of shared values and attitudes in the group. A cultural dimension is a conceptual framework suggested by Hofstede. It describes the effects of a society's culture on the values of its members, and how these values relate to behavior. Individualism and collectivism is a dimension which relates to the relationship between the individual and the group. In individualist societies, people tend to see themselves as independent individuals who must take care of themselves. Ties between individuals are loose. Typical values include freedom, personal challenge and uniqueness of individuals. In collectivist societies, identity is defined more by the characteristics of the collective groups to which one belongs. From birth onwards, people are integrated into cohesive in-groups, which provides them support and protection. People are more interdependent. However, if the individual does not comply to the rules of the group, the results can be severe. In this essay, the differences between individualist culture and collectivist culture will be evaluated. To begin with, the way culture affects construal of self will be explained.
