Freud and Human Behavior


I believe Sigmund Freud most accurately identifies human behavior. Freud’s earlier medicinal studies show his intelligence because of the difficulty of such a subject. Even though the Victorian era and the anti-Semitism brought about by the world war influenced Freud, it was not to the point where it discredits all his findings. Freud theorized that everything thought, dream, slip of tongue, etc. is caused by behavior and thus sub-conscientiously done on purpose.

Freud’s three divisions of consciousness: 

conscience, preconscious, and unconscious are pretty accurate especially for his time. For Freud to be the first person to link the unconscious with everyday shows his enormous psychological talent.

The id, ego, and superego are also Freud’s concepts which I believe also most accurately explain human behavior as it relates to the brain and our thought processes. These are very good explanations as to why people act the way they do. The id is the instinctual part which acts simply on pleasure and immediate gratification. Primary process is the response that the id makes to the realities of life. It is why we don’t sit down and smoke a pack of cigarettes and eat a box of donuts every time we feel like it. The superego is the moral and ethical code which keeps us from acting like Heathens. The superego can be influenced by our parents or may other outside stimuli. The ego balances the id and super ego to allow for some pleasure but also with some responsibility. Sometimes I realize my id is not being balanced out when I try to convince myself something to do is okay, much like the classical devil and angel perched on conflicting minds shoulder.

Freud’s ideas about emotional energy and instinct as well as the true motivation behind every human’s actions are interesting, though not 100% accurate all the time. Eros is the human sex or “life instinct”. Thanatos is the aggressive or “death instinct.”Freud believes all human action is a result of these two instinctual behaviors. I do not fully believe agree with this theory because I think people tend to have ulterior motives besides sex, however, I agree with too many other basic ideas of Freud for these disagreements to adequately change my decision as to which theory I agree with.

Freud’s idea’s about happiness I also find relatable and thus accurate. Negative happiness is avoiding pain whereas positive happiness is seeking pleasure. It is much easier to be unhappy than happy and it is also easy to give up seeking happiness; however, without pain, pleasure wouldn’t be so special, and we wouldn’t know how good we had it. Freud’s ideas on civilization are also interesting especially as it pertains to guilt within a person.

I agree with Freud’s thoughts about anxiety. Realistic anxiety is actually something to be worried about. Neurotic anxiety and moral anxiety play more into Freud’s model of the id, ego, and superego. Freud was big on the subconscious which is also something I find myself fascinated with. The importance of the subconscious, especially as it relates to dreams, has been adequately disproven however the subconscious remains very interesting to me today.

Lastly, no paper would be done talking about Freud until his infamous reasoning that every human action is in some way related to sex.  Though his most radical ideas about human sexuality have been disproven, the human sex drive is an unmistakable influence on behavior and personality. The Erogenous zone is where sexual pleasure comes from. This pleasure is what Freud believes is the basis for all human action, at any age. From the oral stage to the genital stage, Freud believed sexuality influenced mankind of all ages to the point of affecting personality and everyday behavior.

SPSS Assignment - Psychology

Suppose a researcher was interested in studying the differences between males and females in SMS text messaging usage. To test whether there was a difference in text messaging between genders; the researcher took a random sample of 100 students at State University Tech (50 males and 50 females). 

He provided these students with a survey that asked questions such as 1) do you have a cell phone; 2) do you have a plan that includes text messaging, 3) are you limited in the number of text messages you can sent per month, etc. After getting this information, the researcher excluded participants that did not have cell phones, did not have plans that allowed for text messaging, and those people with plans that limited the number of text messages.

 He did this to control as many variables as he could as to not confound (mess up) his experiment. After weeding out participants, his final sample consisted of 25 females and 25 males (N = 50).

To begin the experiment the researcher asked each participant to count the number of text messages they send for 4 weeks (1 month). This was the researcher’s dependent variable. He received the information from each participant and placed the data into SPSS. The data are on blackboard under “Assignments” under the file name test message data for SPSS assignment. Use SPSS to calculate the appropriate statistical test for the given data set. Write up your results as you would in a scientific, peer-reviewed journal. The write up should be in APA format and include, at least, the obtained value, the significance level, and the interpretation of the significance level.


T-TEST 

Assume an experimenter is interested in determining the effects of an early intervention program on the overall verbal skills of a group of underprivileged children. The experimenter randomly assigns children into one of two groups: aggressive, early intervention, and passive, early intervention. After being on the program for six months, the children are administered an achievement test. Now you must determine if there is a difference between the results of the two intervention programs based on achievement test scores. Further, you must decide which intervention led to higher scores (if there was a difference between the interventions). The data are on blackboard under “Assignments” under the file name achievement test scores for SPSS assignment.

Use SPSS to calculate the appropriate statistical test for the given data set. Write up your results as you would in a scientific, peer-reviewed journal. The write up should be in APA format and include, at least, the obtained value, the significance level, and the interpretation of the significance level.

CORRELATION 

A researcher wishes to test part of the Addictive Personality theory, that individuals addicted in one area tend to be addicted in other areas. Specifically, the researcher wants to find out if there is a relationship between alcohol abuse and gambling abuse among persons incarcerated for substance abuse. A random sample of 10 male inmates from Ruston Parish correction center is selected from the population of inmates serving time for substance abuse. Each man is tested on two major addiction scales, Substance Abuse Subtle Screening Inventory and the Gambling addiction Index (GAI). Higher scores indicate greater addiction. The data are on blackboard under “Assignments” under the file name addiction data for SPSS assignment. Use SPSS to calculate the appropriate statistical test for the given data set. Write up your results as you would in a scientific, peer-reviewed journal. The write up should be in APA format and include, at least, the obtained value, the significance level, and the interpretation of the significance level.

ANOVA 

A researcher is interested in whether a significant trend exists regarding the popularity of certain work shifts among police officers in. A random sample of 16 uniformed officers was selected from a large metropolitan police force. The officers are asked to use a scale to score how much they liked working each shift (1-10 scale with higher numbers meaning they enjoyed working that shift more). 
The shift choices were the morning shift (1st shift), the afternoon shift (2nd shift), and the late night shift (3rd shift). Further, the experimenter wanted to find out if time spent on the police force influenced scores. Hence, the researcher separated the officers into two groups: veterans and novices. The researchers question: is there a difference in shift preference, if so, which shift is preferred? Is there a difference between the veteran officers’ preference of shifts and the novice officers’ preference of shifts? The data are on blackboard under “Assignments” under the file name police data for SPSS assignment. Use SPSS to calculate the appropriate statistical test for the given data set. Write up your results as you would in a scientific, peer-reviewed journal. The write up should be in APA format and include, at least, the obtained value, the significance level, and the interpretation of the significance level.

Pay attention to the following instructions:
Directions: Read the following summaries and conduct the appropriate statistics using SPSS. Write up your results as you would in a peer-reviewed journal.

Psychology 300 'Null Hypothesis'

Example 1

In regards to probability, what is the additive rule? Provide an example. Given a set of mutually exclusive events, the probability of the occurrence of one event or another is equal to the sum of their separate probabilities. 
What is the probability of a randomly choosing student at Tech having a compact car (A), or an SUV (B), P(A) = .6, P(B) = .3P(A or B) = .6 + .3 = .9

In terms of probability, what is the multiplicative rule? Provide an example. The probability of the joint occurrence of two or more independent events is the product of their individual probabilities.

Suppose we have a bag of coins: 30 quarters, 15 dimes, and 55 nickels.P (quarters) = .30P (dimes) = .15P (nickels) = .55
The probability that we draw a quarter on the first trial and a quarter on the second trial:
.30 X .30 = .09
The probability that we draw a quarter on the first trial and a dime on the second trial: 
30 X .15 = .04

Regarding the normal curve, what percentage of the population will fall between +1 and -1 standard deviations? What percentage will fall between +2 and -2 standard deviations? 68% of the pop will fall in the +1 and -1 range 96% of the pop will fall between +1 and -1

What is the difference between the Null hypothesis (H0) and the Research hypothesis (HA)? Provide examples of both. A null hypothesis is a hypothesis that may be falsified using a test of observed data, where as a research hypothesis is a statement created by a researcher when they speculate upon the outcome of a research or experiment.

What is the difference between Nominal and Ordinal data? Please provide examples of both. (I know I said no more question about this stuff until the midterm, but someone got them mixed up on the paper assignment) Nominal Data is the values of the scale have no 'numeric' meaning in the way that you usually think about numbers. People or objects with the same scale value are the same on some attribute. Categorical label; Example: Male/Female. Ordinal Data is measured in first second or last, but the ranks do not add any other additional information about the ranking. Example: placing first, second, or third in a race

Example 3

When should you use an ANOVA (F-test)? Use ANOVA to analyze variance. There must be more than 2 groups, more than one dependent variable, and either interval or ratio data. When should you use a t-test? Use a t-test if you are trying to find out if the variance between groups is significant. It is looking for differences. There must be 2 groups and the data must be interval or ratio.

When should you use a correlation? Correlation is used to find relationships amongst groups. What is the difference between an independent and dependent variable? An independent variable is the variable which researches have control over and can manipulate to affect the dependent variable. The dependent variable is being measured and is affected by the independent variable.

What is your favorite statistical test? My favorite statistical test is the t-test because if someone had a stutter you couldn’t tell if they were talking about just a regular test or a t-test
