Emotions vs Feelings

Emotions include: 1) Affect (the feeling, subjective) 2) Brain activity in certain areas 3) Body physiology and arousal 4) Facial expression 5) Body language and posture

If it’s not universal around the world, it’s not an emotion. Emotions are applicable to everyone, but feelings are subjective.

Emotion is an automatic, built-in reaction to a stimulus that has evolved as a brain/body response.

Feeling is more complex, involving cognition and thinking.

Both may be conscious or unconscious.

Consciousness – Awareness of the world

Antonio Damasio (married to Hannah Damasio, famous brain imager) Emotions and consciousness arise from body representations

Joseph LeDoux Found that the amygdala is a major emotion center, especially for fear.

Emotional valence refers to the quality of pleasant or unpleasant.
Valence – pleasant or unpleasant quality to emotion. Positive/Negative valence.


James – Lange Theory (William James/Carl Lange, US and Netherlands, same idea) Stimulus > Physical Reaction > Emotion
Emphasis on body reaction

Cannon – Bard Theory (Walter Cannon/Philip Bard)

Stimulus > Brain Activity > Emotion Emphasis on the brain

Schacter – Singer Theory Stimulus > Cognition > Emotion Emphasis on cognition

Social Comparison Sometimes we don’t know what we’re suppose to feel/do/how to act, so we look at people around us to get cues on what we should do.

The two roads of emotions: Low Road – Fast, without thinking, without judgement, unconscious part High Road – Slower, includes cognition and reasoning, conscious part


Charles Darwin Got ideas from French scientist Guilllaume Duchenne Duchenne put electrodes on peoples faces and studies facial muscles

Pan Am Smile (fake) Forced

Duchenne Smile (genuine) Instictive

Facial Feedback Hypothesis Smiling makes you feel happier!

Affect Display Subjective personal feeling that you have How is it that facial muscles are connected to emotions you’re feeling?

Paul Ekman Spent 8 years studying facial muscles FACS: Facial Action Coding System Lie To Me (TV show) is based on the work of Paul Ekman

Microexpressions Unconscious quick facial reactions to emotion
Nearly every liar’s face reveals micro-expressions.
Micro-expressions can appear and disappear in microseconds.

Lie Detection The polygraph measures many physiological responses base on the idea that a liar will react physically automatically. This idea has many problems and the polygraph is not a good lie detector.
Guilty Knowledge A liar has some knowledge other people don’t. Ask a question indirectly about things related to something that won’t cause nervousness.

Brain Fingerprinting Based on the idea that brain waves (EEG) can detect lies

ERP – Event Related Potential Change in brain waves as experience a stimulus ERP is either a positive (P) or negative (N) change in brain waves that occurs milliseconds after the stimulus is presented. P300 occurs after a meaningful stimulus N400 occurs if a person experience an unexpected stimulus


Psychopath – APD – Antisocial Personality Disorder

APD -Psychopath or Sociopath -Lacks Conscience -Harms others with no remorse or guilt -About 4%; more common in men -Criminal, uses people, con artist

Ted Bundy – Psychopath and Serial Killer -Charming murderer

The Beginning

...In the beginning God create the heavens and the earth. At the time the earth was like a void, darkness everywhere consuming the planet, and God said four words, “and let there be light.” Then there on that planet earth God separated light from dark. He blessed the light and called the light day, and he cursed the dark and called it night. The second day has arrived. God then said the waters from waters, and called to the expansion of heaven. The third day came. God wanted to fill the gap in the water, so God created dry land, and made the gathered water seas. Now he said there should be vegetation on the earth. The third day has passed. God said let there is the expansion of time telling from the seasons, and let there be light at night call it stars. The fourth day has passed. God then created every living creature to roam the earth, and blessed the bird. The fifth day has passed. God said I must make man I will make man in my own image of me, and blessed these creatures. The sixth day has passed. On the day of Creation God rested. God made a deal with man everything you see on earth is yours, for this is Eve’s garden. You may take any fruit, except the tree of knowing good and evil. If you eat the tree of knowing of good from evil you will surely die. Later the serpent temps Eve to go and eat the forbidden apple. At first she said no put in the serpents crafty ways, he convinced Eve into eating the apple. Not only was he able to trick Eve but also he made Eve convince......

...Computer crime Computer Crime Definition A computer crime is any illegal action where the data on a computer is accessed without permission. This access doesn't have to result in loss of data or even data modifications. Arguably the worst computer crime occurs when there are no indications that data was accessed. Computer crime is often attributed to rogue hackers and crackers, but increasingly organized crime groups have realized the relative ease of stealing data with relative low-level of risk. Government organizations are also rumored to be involved with hacking in to computer systems, but the legality of such actions is far too grey an area to be discussed here. Computer crime, or cybercrime, refers to any crime that involves a computer and a network, where the computers may or may not have played an instrumental part in the commission of a crime.[1] Netcrime refers, more precisely, to criminal exploitation of the Internet.[2] Issues surrounding this type of crime have become high-profile, particularly those surrounding hacking, copyright infringement, child pornography, and child grooming. There are also problems of privacy when confidential information is lost or intercepted, lawfully or otherwise. On the global level, both governments and non-state actors continue to grow in importance, with the ability to engage in such activities as espionage, financial theft, and other cross-border crimes sometimes referred to as cyber warfare. The international legal system......

Old People Are Jealous of Teen's Bodies

...purpose. It is understandable that a dress code should be enforced in order to maintain individual decency. Overwhelmingly, most rules are especially catered against the female sex. The most controversial topic that females students argue against is the restriction of leggings – a form fitting garment made out of spandex, cotton, and other stretchable material, covering the legs’ whole length, void of pockets, buttons and a zipper. Leggings are a more comfortable alternative to other pants with harsher fabric. The administration claim that because of its fitting material and the way it clings onto a girl’s bum – like any other pair of pants would – it would distract the male students who are, “trying to concentrate on their education.” Many people who oppose this rule do not understand why Buena claims that these bottoms are so significantly more exposing and inappropriate than other trousers and how it has the power to sway the attention of males, temporarily dominating their concentration in a classroom environment. Are regular jeans, sweatpants, khakis, or any other variety of pants not supposed to fit comfortably around a person’s hips, butt, and thighs similarly? Females should not be harassed and assumed of purposefully consuming male attention for wearing something they find comfortable and suitable for them. It is understandable for the need to keep students from wearing certain revealing clothing – I personally find it disturbing when a female purposefully wears......

...requires one foot being out front 4. It seems like we here about an elder individual falling every single day – about one third of older people who live at home fall at least once a year, and people who live in a nursing home fall even more often (1). With that said, would you believe me if I told you that the fear of falling is much more detrimental to the elderly population than the act of falling itself? Psychological stability is always vital to any individual, but it is even more so to an elder individual. Their entire well being is centered on their psychological state – so if they are constantly living in a state of fear – they’re going to suffer immensely. Take this quote for example, “Excessive fear of falling can cause seniors to limit their participation in physical and social activities, so that they become physically deconditioned, socially isolated, and depressed (2). Thus, fear of falling can contribute to both functional decline and impaired quality of life. The fear of falling hurts them way more than they could ever realize. They often times decide to just sit in a chair for the rest of their lives, essentially give up on their physical well-being, simply out of their fear of falling. Community-based epidemiologic studies have found that at least 21 percent of elderly people experience some degree of fear of falling (3). At the very minimum, one in every five elders fears falling, meaning one in every five elders is......

...simplest form it included “keyword stuffing”. That was the practice of making the target keyword terms the same color as the background of a webpage. The search engines could see the terms (and record the keyword density), but regular visitors couldn’t. In effect you were presenting one thing to the search engines and another to your visitors. Many people also used automated software programs to create thousands upon thousands of pages of rubbish content (what used to be referred to as “doorway pages”), tweaked with the ideal keyword density in order to really game the system. Aggressive “search engine cloakers” also showed up. - 9 - The Ultimate Link Building Dossier – Duncan Carver – Copyright 2010 – 2013 - All Rights Reserved The Ultimate Link Building Dossier This crowd presented one page of content to the search engines optimized to what the computer algorithm wanted to see - only to present an entirely different page to search engine visitors - a much more advanced technique of “keyword stuffing”. This was not a problem so long as things remain targeted, but when your 10 year old sister starts looking for “Winnie The Pooh” and ends up on a porn site, well, it’s not rocket science to see that something needs fixing there. So it didn’t take long before Google realized they needed more control. Essentially Google could become devalued as a service provider of accurate search results and alienate their users if they didn’t......

...I learned more about the world (both of more experience and disappointment of the reality) that I truly appreciated the stories and interpreted them as types of satire. Taking The Handsomest Drowned Man in the World and A very Old Man with Enormous Wings into an adult’s point of view, and reflecting on them more critically, I noticed that these two stories were more profound. While The Handsomest Drowned Man in the World seems to be a story about how the village people appreciated and the dead man and were influenced positively by him, looking at this from another perspective, we can see how shallow these people were. The villagers took a foreign dead man as a god-like figure just by his looks, and changed their village completely because of him. The once “[desolated] … streets, [dry] … courtyards, [narrow] … dreams” all changed to “gay colors, … plating flowers …” just to make “Esteban’s memory eternal.” It seems almost sarcastic to make a story based on such easily influenced people – influenced no other than a corpse. Marquez may have wanted children to see how some people, even a dead one, can influence others through this story. However, taking a distant look, he may have wanted adults to see the hidden foolishness beneath this story. A Very Old Man with Enormous Wings also seems to have a hidden meaning. From a child’s point of view, this may be a story about how a poor angel finally frees from dominating house owner. However, to the adult reading this, this may be......

People Are Too Dependent on Computers

...People are too dependent on computers The question is, are people in general becoming too dependent on computers? What would happen if your computer crashed? What would you do if you misplaced your cell phone? If just contemplating about these situations gives you concern, there are others that share your interest. Majority of us rely so much on technology these days that losing it, even for a day, would be very inconvenient, and for many, life-changing. What would your day be like if you were to give up technology for a day? Would your day be ruined if you could not record every moment of your day on Facebook or Twitter (Kirschner, 2013)? Personally, the answer is yes. With the rapid change in technology as it evolves, it has become an integral part of our day to day lives. Everyone wants to be connected without being connected, and in so doing spend majority of their time using computers, smartphones iPad and many other wireless gadgets. We utilize these devices for business as well as personal consumption. Thinking back, my supervisor, and I share the same office space and instead of communicating with me verbally, he would send me an email while staring me right in the face. After sending the e-mail, he would then tell me to check my email. As a kid growing up without today’s technology, I had to read books in order to complete my assignments. I also had to write my assignment instead of using a key board and focus on learning to write using correct grammar and......

Microsoft Beginnings

...Microsoft Microsoft started from humble beginnings in 1975, and soon rose to become one of the biggest companies in modern history. Today, Microsoft is having record revenues, making a total of $18.06 billion dollars last quarter (Forbes). Microsoft affects almost everyone’s life in the US daily, whether it is kids on their Xbox, to desk workers using Windows Office each day to accomplish their work, people use Windows every day. From Microsoft’s early beginnings to its multibillion-dollar company today, Windows has had success from the start, and will continue to for the coming decades. Two men in 1975; Bill Gates and Paul Allen founded Microsoft. (History of Windows) They started out with MS-DOS, their first operating system. The companies’ first headquarters was in Albuquerque, New Mexico, but after signing some pivotal contracts with IBM, they moved to their headquarters in Bellevue, Washington in 1979.(History of Windows) Working side by side with IBM to develop OS/2, Microsoft released their new product, Microsoft Windows. It was a graphical extension of MS-DOS. On March 13th, 1986, Microsoft went public, which would result in 4 billionaires and an estimated 12,000 millionaires being created from the ensuing rise in stock. (Forbes) Along with its partnership with IBM came allegations that they were trying to monopolize the computer industry.

Economy relies on the e-commerce transactions to make business and increase profits. But, people have been affected as well; society relies on computer technology in every level. With the integration of the internet, the dependency on computers has increased dramatically. What is the result of the side effect of having computerized our world? It seems it was just a few years ago when computers were exclusive for businesses using mainframes to process calculations. But, computers have gone from a luxury to an everyday need. The benefits from computers have revolutionized the entire world. In the old days, telecommunications were limited; telegrams and letters were used as a medium of sharing information before technological advancement was developed. Now, computers have changed the telecommunications. People can “surf” on the web and visit any country in the world in less than 30 seconds, book a flight in 5 minutes or purchase a pair of jeans in 2 minutes.
