Online Research About Psychology + IT = ?



This time, I'll share the result of my online research about Information Technology students who have learnt Psychology. This research is only for the University of North Sumatra. In this research, they are being asked some questions about the impact of Psychology in their studies, especially IT.


According to my research that I've done, all of them feel that IT students need to learn Psychology and more than 70% of them said that Psychology is really important for them. Almost all of them said that they have got the benefit from learning Psychology. Most of them can understand more about themselves and some of them know more about people's behavior. 80% of the respondents are interested in learning Psychology and want to know more about it.

Here's the chart below showing their responses according to the research:

Interest in learning more


From the researched that I've done, I can conclude that Information Technology students are very enthusiastic in learning Psychology.

My Testimony:
This is my very first time in doing a research and this is my first time too in doing an online research. In my opinion, it is very effective to do an online research compared to manual research (paper-based). So for those who want to do a research, I suggest you to do online research because I think that nowadays, people tend to ignore the paper-based research that can't be filled only by clicking.

Sensation And Perception

This time, I'm going to explain about sensation and perception and my own experiences involving those two.

Sensation is the process of receiving information in the form of stimulation received by the human senses. Sensation is receiving information without interpreting the information. The sensation can be either internal or external stimulation. External sensations from outside through our senses: the eyes, ears, nose, tongue and skin. Eyes receives sensations such as vision, ears receive sensations such as hearing, skin receives sensations of touch, heat, pressure, and so on. Internal sensation is a sensation from ourselves. Such as hunger.

If a person receives the same sensation or stimulation repeatedly, the brain's response to that sensation will be reduced. It's called sensory adaptation. The example in daily life is when we first enter the swimming pool, we will feel very cold but eventually, the cold will be reduced until we don't feel cold anymore.
Perception is the process of interpreting the sensation. In other words, it is the process of translating the information which we received. The perception of each person to a stimulation is different. This is due to the experience, the history of life, psychophysics and perceptual distortions. Perceptual distortions can be physical appearance, stereotypes, first impressions (halo effect), and the "tendency to judge others immediately". Example: A person tends to see the physical shape of a person and directly judge that person, before knowing more about him/her. This will form different perceptions compared to people who really know that person well.

Different perceptions that emerged among people are mostly associated with the vision. According to Gestalt, there are 5 things which influence people's perceptions:
1. Figure-Ground
People tend to see the object that appears as figure, and other objects as ground.
2. Proximity
Objects that are close with other objects tend to be a group.
3. Continuity
Objects that are connected with other objects tend to be a group.
4. Similarity
Objects that are similar tend to be a group.
5. Closure
Objects that closed tend to be a group.

Misperceptions are very common. This misperception is called illusion. The illusion can occur naturally or accidentally. Intentional illusion is an illusion deliberately made on an object. An example of this is an optical illusion. That is an illusion caused by an error catching stimulus by the human eye. One of illusion examples is Zollner Illusion.


Now, I'm going to tell you a bit about my experience involving sensation and perception.
I'll start with the sensation that I received using my eyes. That time, when I was playing badminton, I saw one of my classmates was playing badminton too with a girl at the court beside mine. He looked so happy and the girl was enjoying the game too. That is the sensation I got. At that time, my perception is the girl must be his girlfriend! So I came to him and after we greeted each other, I directly made fun of them, saying that they looked so suitable for a couple, like husband and wife. But I was definitely wrong! They are not a couple! The girl is his cousin +.+
That was a huge misperception. Then I quickly said goodbye after I apologized.
So, the sensation I got is "I saw my friend played badminton with a girl" and the perception is "I thought the girl is his girlfriend."

I'll continue with the second experience of mine. This time, I'll tell you guys about the sensation I received using my ears.
I had a promise with my classmates to go hang out together on that day. But suddenly, I got into a fight with my little sister and then quarreled with my mom too. (Such a bad day!) I had a feeling that my mom won't let me go out as a punishment. But I tried not to think about that possibility. I got into my room, took a bath, changed clothes and got prepared. After I had finished everything, I crept outside my room and passed through the living room where my mom was sitting on sofa. I took a deep breath as I hold the door handle and suddenly my mom yelled at me. (Oh, crap! She won't let me go anywhere today!) But then she told me that there was a dead cockroach near the door. She was just warning me about dead cockroach! Not about anything else. She scared me to death. Another misperception.
So this time, the sensation I got is I was being yelled and my perception is I was going to stay at home whole day.
That's all.. I hope you guys can understand more about sensation and perception..

Operant Conditioning (Group 1)


Operant Conditioning
Learning From The Consequences Of Your Behavior


Group members:

If you were to move into a new town and you came to a park then an attractive and pretty girl spoke to you, you would probably keep going to that park again. 

The changing frequency of people’s behavior caused by the consequences of their actions is called operant conditioning. People learn from the consequences of their actions and their behavior changes.


Operant Conditioning was first described by American psychologist, Edward Thorndike (1991). At first, Thorndike was interested in the question of animal intelligence, which he investigated using an apparatus he called a "puzzle box." A hungry cat was placed inside the box, food was placed outside, and the cat's efforts to escape were observed. With each trial, the cat becomes more efficient at opening the door of the box. Based on these observations, Thorndike formulated the "Law Of Effect", which states that the behavior that yields good consequences will be strengthen, and the behavior that yields bad consequences will be weakened.
Thorndike's law of effect formed the basis for subsequent study of what is now referred to as operant conditioning in contemporary psychology.


There are three ways in which the desirable and undesirable consequences of our behavior influence our future behavior:
1. Positive Reinforcement
2. Negative Reinforcement
3. Punishment

Positive Reinforcement
In positive reinforcement, the consequences of a behavior are positive. This causes the increasing frequency of that behavior. People tend to repeat the behavior that gives them good result. In positive reinforcement, the good result is called positive reinforcer or reward.  Positive reinforcement is used to increase the frequency of wanted behavior.

For example, a lazy child was told by his parents that he would get a bar of chocolate if he can finish his homework before dinner time. Because he liked chocolate so much, he started to do his homework right after he had finished his lunch. As he finished the homework before dinner time, he got the chocolate his parents promised. This keeps repeating for the next days.

From this case, the reward is the chocolate and the behavior increased is finishing homework as soon as possible.

There  are  two important issues in the use of positive reinforcement:
1.Timing.
Reward must be given directly after the behavior wanted. The more delay or time interval between the behavior and the reward, the slower the learning occur. This delay has been referred to as the principle of delay of reinforcement.
For an example, if we were to train our dog to give a “handshake”, we should give our dog a piece of biscuit right after it took its paw and gave us a “handshake”.  Mostly, the optimal time is only one or two seconds. 
2. Consistency in the delivery of reinforcement.
In the beginning of the learning process, the reinforcement must be given consistently after every response. But after the  learning occur, it’s not always important to reinforce every response.
So, if we were to train our dog to give a “handshake”, we should give our dog a piece of biscuit everytime after it succeed shake your hand. But after the dog is well-trained, the biscuit is not always important anymore.

Negative Reinforcement
Sometimes, the increasing frequency of a behavior is to avoid aversive event. If a behavior is able to take away something we don’t like, then we tend to repeat that behavior again and again.
For example, when a naughty child is given punishment by his parents, he cried. To stop his crying, his parents then cancelled the punishment given. The next time he got punishment, he will cry again to make his parents cancel the punishment.
From this example, the increasing behavior is crying. The aversive event being taken away is the punishment.

Negative reinforcement is a very powerful method of reinforcement, so we learn patterns of behavior quickly and easily.

Punishment
Punishment is a negative consequence that leads to a decreasing in the frequency of the behavior that produced it. For example, if you keep talking in class while teacher is teaching infront, a negative consequence will surely occur. The teacher will scold you or give you another type of punishment. And you will probably not try to talk while teacher is teaching again. Punishment can be a valuable way for discouraging inappropriate behavior only if the punisment is appropriately used.


Testimony:
I think positive reinforcement is the best method compared with the other two. So, before we try to give others punishment or negative reinforcement, it's better to give the positive one first. 
I think that's all for this operant conditioning topic. I hope you guys  can understand more about this principle of learning.

The Extraordinary Science of Addictive Junk Food

"As a culture, we've become very upset by the tobacco companies advertising to children, but we sit idly by while the food companies do the very same thing." - Kelly Brownell, Yale University professor of psychology and public health.

On the evening of April 8, 1999, a long line of Town Cars and taxis pulled up to the Minneapolis headquarters of Pillsbury and discharged 11 men who controlled America's largest food companies. Nestle was in attendance, as were Kraft and Nabisco, General Mills and Procter & Gamble, Coca-Cola and Mars. Rivals any other day, the C.E.O.'s and company presidents had come together for a rare, private meeting. On the agenda was one item: the emerging obesity epidemic and how to deal with it. While the atmosphere was cordial, the men assembled were hardly friends. Their stature was defined by their skill in fighting one another for what they called "stomach share" - the amount of digestive space that any one company's brand can grab from the competition.
James Behnke, a 55 year old executive at Pillsbury, greeted the men as they arrived. He was anxious but also hopeful about the plan that he and a few other food-company executives had devised to engage the C.E.O.'s on America's growing weight problem. "We were very concerned, and rightfully so, that obesity was becoming a major issue," Behnke recalled. "People were starting to talk about sugar taxes, and there was a lot of pressure on food companies." getting the company chiefs in the same room to talk about anything, much less a sensitive issue like this, was a tricky business, so Behnke and his fellow organizers had scripted the meeting carefully, honing the message to its barest essentials. "C.E.O.'s in the food industry are typically not technical guys, and they're uncomfortable going to meetings where technical people talk in technical terms about technical things," Behnke said. "They don't want to be embarrassed. They don't want to make commitments. They want to maintain their aloofness and autonomy."
A chemist by training with a doctoral degree in food science, Behnke became Pillsbury's chief technical officer in 1979 and was instrumental in creating a long line of hit products, including microwaveable popcorn. He deeply admired Pillsbury but in recent years had grown troubled by pictures of obese children suffering from diabetes and the earliest signs of hypertension and heart disease. In the months leading up to the C.E.O.  meeting , he was engaged in conversation with a group of food-science experts who were painting an increasingly grim picture of the public's ability to cope with the industry's formulations - from the body's fragile controls on overeating to the hidden power of some processed food to make people feel hungrier still. It was time, he and a handful of others felt, to warn the C.E.O.'s that their companies may have gone too far in creating and marketing products that  posed the greatest health concerns.
The discussion took place in Pillsbury's auditorium. The first speaker was a vice president of Kraft named Michael Mudd. "I very much appreciate this opportunity to talk to you about childhood obesity and the growing challenge it presents for us all," Mudd began. "Let me say right at the start, this is not an easy subject. There are no easy answers  - for what the public health community must do to bring this problem under control or for what the industry should do as others seek to hold it accountable for what has happened. But this much is clear: For those of us who've looked hard at this issue, whether they're public health professionals or staff specialists in your own companies, we feel sure that one thing we shouldn't do is nothing."

As he spoke, Mudd clicked through a deck of slides - 114 in all - projected on a large screen behind him. The figures were staggering. More than half of American adults were now considered overweight, with nearly one-quarter of the adult population - 40 million people - clinically defined as obese. Among children, the rates had more than doubled since 1980, and the number of kids considered obese had shot past 12 million. (This was still only 1999; the nation's obesity rates would climb much higher.) Food manufacturers were now being blamed for the problem from all sides - academia, the Centers for Disease Control and Prevention, the American Heart Association and the American Cancer Society. The secretary of agriculture, over whom the industry had long held sway, had recently called obesity a "national epidemic."
Mudd then did the unthinkable. He drew a connection to the last thing in the world the C.E.O.'s wanted linked to their products: cigarettes. First came a quote from a Yale University professor of psychology and public health, Kelly Brownell, who was an especially vocal proponent of the view that the processed-food industry should be seen as a public health menace: "As a culture, we've become upset by the tobacco companies advertising to children, but we sit idly by while the food companies do the very same thing. And we could make a claim that the toll taken on the public health by a poor diet rivals that taken by tobacco."
"If anyone in the food industry ever doubted there was a slippery slope out there," Mudd said, "I imagine they are beginning to experience a distinct sliding sensation right about now."

Mudd then presented the plan he and the others had devised to address the obesity problem. Merely getting the executives to acknowledge some culpability was an important first step, he knew, so his plan would start off with a small but crucial move: the industry should use the expertise of scientists - its own and others - to gain a deeper understanding of what was driving Americans to overeat. Once this was achieved, the effort could unfold on several fronts. To be sure, there would be no getting around the role that packaged foods and drinks play in overconsumption. They would have to pull back on their use of salt, sugar and fat, perhaps by imposing industrywide limits. But it wasn't just a matter of these ingredients; the schemes they used to advertise and market their products were critical, too. Mudd proposed creating a "code to guide the nutritional aspects of food marketing, especially to children."
"We are saying that the industry should make a sincere effort to be part of the solution," Mudd concluded. "And that by doing so, we can help to defuse the criticism that's building against us."
What happened next was not written down. But according to three participants, when Mudd stopped talking, the one C.E.O. whose recent exploits in the grocery store had awed the rest of the industry stood up to speak. His name was Stephen Sanger, and he was also the person - as head of General Mills - who had the most to lose when it came to dealing with obesity. Under his leadership, General Mills had overtaken not just the cereal aisle but other sections of the grocery store. The company's Yoplait brand had transformed traditional unsweetened breakfast yogurt into a veritable dessert. It now had twice as much sugar per servings as General Mill's marshmallow cereal Lucky Charms. And yet, because of yogurt's well-tended image as a wholesome snack, sales of Yoplait were soaring, with annual revenue topping $500 million. Emboldened by the success, the company's development wing pushed even harder, inventing a Yoplait variation that came in squeezable tube - perfect for kids. They called it Go-Gurt and rolled it out nationally in the weeks before the C.E.O. meeting. (By year's end, it would hit $100 million in sales.)
According to the sources I spoke with, Sanger began by reminding the group that consumers were "fickle." (Sanger declined to be interviewed.) Sometimes they worried about sugar, other times fat. General Mills, he said, acted responsibly to both the public and shareholders by offering products to satisfy dieters and other concerned shoppers, from low sugar to added whole grains. But most often, he said, people bought what the liked, and the liked what tasted good. "Don't talk to me about nutrition," he reportedly said, taking on the voice of the typical consumer. "Talk to me about taste, and if this stuff tastes better, don't run around trying to sell stuff that doesn't taste good."
To react to the critics, Sanger said, would jeopardize the sanctity of the recipes that had made his products so successful. General Mills would not pull back. He would push his people onward, and he urged his peers to do the same. Sanger's response effective ended the meeting.
"What can I say?" James Behnke told me years later. "It didn't work. These guys weren't as receptive as we thought they would be." Behnke chose his words deliberately. He wanted to be fair. "Sanger was trying to say, 'Look, we're not going to screw around with the company jewels here and change the formulations because a bunch of guys in white coats are worried about obesity.' "
The meeting was remarkable, first, for the insider admissions of guilt. But I was also struck by how prescient the organizers of the sit-down had been. Today, one in three adults is considered clinically obese, along with one in five kids, and 24 million Americans are afflicted by type 2 diabetes, often caused by poor diet, with another 79 million people having pre-diabetes. Even gout, a painful form of arthritis once known as "the rich man's disease" for its associations with gluttony, now afflicts eight million Americans.
The public and the food companies have known for decades now - or at the very least since this meeting - that sugary, salty, fatty foods are not good for us in the quantities we consume them. So why are the diabetes and obesity and hypertension numbers still spiraling out of control? It's not just a matter of poor willpower on the part of the consumer and a give-the-people-what-they-want attitude on the part of the food manufacturers. What I found, over four years of research and reporting, was a conscious effort - taking place in labs and marketing meetings and grocery - store aisles - to get people hooked on food that are convenient and inexpensive. I talked to more than 300 people in or formerly employed by the processed-food industry, from scientists to marketers to C.E.O.'s. Some were willing whistle-blowers, while others spoke reluctantly when presented with some of the thousands of pages of secret memos that I obtained from inside the food industry's operations. What follows is a series of small case studies of a handful of characters whose work then, and perspective now, sheds light on how the foods are created and sold to people who, while not powerless, are extremely vulnerable to the intensity of these companies' industrial formulations and selling campaigns.

This article is adapted from "Salt Sugar Fat: How the Food Giants Hooked Us," which will be published by Random House this month.
