      Evolutionary reward...the teen phase of development is what has pushed us forward with the new discoveries
  • So that’s why you have parents to act as your prefrontal cortex,” Frank jokes. Then, all too often, he says, “you reach adolescence and you don’t listen to your parents anymore.”

  • observing and measuring which parts of the teens’ brains are most active
  • During the risk-taking and rewards-based tests, one region deep inside the brain shows more activity in adolescents than it does in children or adults, Crone says. This region, known as the ventral striatum, is often referred to as the “reward center”
  • Adolescents are particularly sensitive and responsive to influence by friends, desires and emotions, researchers say. It’s one of the hallmarks of this stage in life.

  • brain is locked in a tug-of-war between the logical pull of the prefrontal cortex and the impulsive pull of the ventral striatum.
  • toward years of serious risk-taking
  • prefrontal cortex seems to lag in developing. It turns out this delay serves an important evolutionary function,
  • So it’s important that the master planner not be too rigid or restrictive during adolescence. Instead, it stays open to learning.
  • One of the processes involves axons, or fibers that connect nerve cells. From infancy, these fibers allow one nerve cell to talk to another. Throughout the teen years, fatty tissue starts to insulate the axons from interfering signals — it is a bit like the plastic that coats electrical cables.
  • In axons, the insulating tissue allows information to zip back and forth between brain cells much more quickly. It also helps build networks that link the prefrontal cortex with other brain regions, allowing them to work together more efficiently.
  • The second key process involves synapses. A synapse is like a dock between nerve cells. Nerve cells communicate by transmitting chemical and electrical signals. Those signals move through the synapses.
  • brain starts discarding many of these connections
  • So the brain strengthens the synapses it really needs and eliminates those that either slow things down or aren’t useful.

Our brains are wired for storytelling | Socialgrrrl World - 1 views

  • it is part of the human experience to want to communicate and share with each other through stories.
  • Even in a digital age, oral stories continue to be committed to memory and passed from generation to generation – fairytales, mythology, legends tie us to our history and give us a sense of belonging.
  • eople can only hold attention for 10 minutes at a time before they tune out

  • we as marketers need to understand how we can adapt it to social media and digital technology.
  • The brain is so fascinating. It has been the focus of science and mystery alike trying to understand how it works including why it seems so wired for storytelling.
  • One thing we know is that large amounts of data or information with no context cannot be easily remembered;
  • The human brain can only hold about seven pieces of information for less than 30 seconds, which means, your brain can only handle a 7-digit phone number
  • omething interesting and relevant needs to happen in a lecture or presentation every 10 minutes so that the audience pays attention and remembers what you say
  • Hearing information told in the narrative from another person helps to reach the old brain, triggering emotion as we imagine ourselves in the story reacting and feeling.
  • Repeat to remember
  • ure data with no context is extremely difficult for the brain to put into long term memory –
  • thinking about fantasy first prepares us for situations that may come up in real life, narrative provides context.
  • The ‘old brain’ in humans is driven by basic primitive instincts such as hunger, sex and fight-or-flight are also intrinsically tied to emotion. 
  • The old brain does not understand numbers or abstract terms, like “integrated approach” or “comprehensive solution” which are an evolutionary part of our new brain
  • he old brain is influenced by beginnings and endings like in a simple story structure with patterns we can recogniz
  • It is important to not only recognize the history behind storytelling but explore why it is so prevalent across centuries, cultures and mediums
  • hearing a story in narrative about a specific situation actually helps us prepare for when this situation potentially happens to us.
  • share information with each other and will continue no matter what the medium.
  • We want stories to be memorable so they can easily be shared with others creating word of mouth.

Love and Addiction: 4. "Love" as an Addiction - 0 views

  • a human relationship can be equivalent psychologically to a drug addiction.
  • Chein, Winick, and other observers interpret drugs to be a kind of substitute for human ties. In this sense, addictive love is even more directly linked to what are recognized to be the sources of addiction than is drug dependency.
  • Freud noted important parallels between love and another psychologically compelling process—hypnotism.
  • ...25 more annotations...
  • From being in love to hypnosis is evidently only a short step.
  • Love is an ideal vehicle for addiction because it can so exclusively claim a person's consciousness.
  • Someone who is dissatisfied with himself or his situation can discover in such a relationship the most encompassing substitute for self-contentment and the effort required to attain it.
  • When a constant exposure to something as necessary in order to make life bearable, an addiction has been brought about, however romantic the trappings. The ever-present danger of withdrawal creates an ever-present craving.
  • Since the person who addicts himself to a lover has essentially the same feelings of inadequacy as the drug addict, why should such an individual choose another person, rather than a drug, for the object of his addiction
  • found that sexual relationships in the lower class tend not to involve as great a degree of life-sharing.
  • "The lower class person . . . is less dependent on people, and more oriented toward those gratifications which can be achieved without complicated cooperation of other human beings."
  • The latter can be defined as the need to cling to one human object for love and support. That object may not even be a true person, but only a conception of a person.
  • When people are economically comfortable but still sense a large deficiency in their lives, their yearnings are bound to be more existential than material. That is, these yearnings are tied into their basic conception of and feelings about themselves
  • A person feeling this inner emptiness must strive to fill it. In relationships, this can only be done by subsuming someone else's being inside yourself, or by allowing someone else to subsume you.
  • The result is a full-fledged addiction, where each partner draws the other back at any sign of a loosening of the bonds that hold them together.
  • The relationship was an addiction. F. Scott Fitzgerald and Sheilah Graham sealed themselves off from the outside world by neglecting their work and by dropping all their other personal relationships in Hollywood.
  • The belief which underlay this feeling—and all of the relationship—was expressed by Graham when she said that "my living began when he arrived." If there is a need to participate in every aspect of another's life, its conclusive form is the complete control of or reliance on another, so that one person does not exist without the other's being there, too. This is the essential similarity to drug addiction, where a person feels he is living only when he is on the drug. The ultimate statement of the desire to be consumed by love is in the last passage quoted from Graham, where she wanted to crawl into Scott's mind, lose her consciousness in his, and form one human entity out of two incomplete beings.
  • The sadistic person is as dependent on the submissive person as the latter is on the former;
  • The difference is only that the sadistic person commands, exploits, hurts, humiliates, and that the masochistic person is commanded, exploited, hurt, humiliated. This is a considerable difference in a realistic sense; in a deeper emotional sense, the difference is not so great as that which they both have in common: fusion without integrity.
  • Above all else, these extreme emotional reactions conclusively establish that the relationship was an addiction. All along, the lovers' actions toward each other were dictated by their own needs. Therefore, when their connection was severed—even temporarily—they had no basis on which to relate. Each was incapable of respecting, or even conceiving of, the other in his or her own terms, as continuing to live his or her own life. It was impossible for either to be concerned about the other's well-being; if the one lover wasn't there to satisfy the other's needs, then he or she ceased to exist.
  • Because an addiction is sought only for the total experience it provides, it can only be accepted emotionally in that form.
  • Love is the opposite of interpersonal addiction. A love relationship is based on a desire to grow and to expand oneself through living, and a desire for one's partner to do the same.
  • Anything which contributes positively to a loved one's experience is welcomed, partly because it enriches the loved one for his own sake, and partly because it makes him a more stimulating companion in life.
  • If two people hope to realize fully their potential as human beings—both together and apart—then they create an intimacy which includes, along with trust and sharing, hope, independence, openness, adventurousness, and love.
  • If a person loves only one other person and is indifferent to the rest of his fellow men, his love is not love but a symbiotic attachment, or an enlarged egotism.
  • the tendency to regard social partners as commodities. People who show this orientation "fall in love when they feel they have found the best object available on the market, considering the limitations of their own exchange values."
  • Fromm therefore stresses that the respect inherent in all love requires a lover to think, "I want the loved person to grow and unfold for his own sake, and in his own ways, and not for the purpose of serving me."
  • An independent, open person exploring life seriously will instinctively (if not consciously) consider whether someone has anything of substance to add to his or her existence.

  • Three quarters of all people inherit a version of this gene; it then enhances the brain’s ability to think by improving the information processing in the prefrontal cortex.
  • his gene also shapes and controls the nerve circuit closely involved with schizophrenia, hence the connection between genius and madness.
  • This also suggests that schizophrenia may be the downside to an evolutionary change that improved our chances of survival and our fitness, by improving our intelligence and creativity.
  • He found that first-degree relatives of psychotic patients are found to be more successful in attaining recognition in several fields of intellectual endeavour than the general population of the area in which he studied: Iceland. He also found that the fields in which they attained recognition were areas of creative and scholarly excellence.
  • It could be perhaps that although psychosis can cause enhanced creativity, the patient is too inhibited by their condition to use it to their advantage.
  • over-inclusive thinking, would facilitate originality which, in optimum circumstances, would lead to creativity.

The Teen Brain: It's Just Not Grown Up Yet : NPR - 0 views

    • olivia amiel
       
      I think this article is useful because it speaks about how parents are affected by the attitude of their teenager. It also speaks about how the teenage brain thinks differently than others, how the frontal lobe can affect selfishness of the teenager. It also mentions our vulnerability to addiction and what makes us attracted to addiction. This was a very interesting article because this is some stuff we will probably explore in class. 
    • Danielle Waid
       
      This is a good website because it gives a lot of information on how the teenage brain works. (The information given is the information we spoke about in class). It gives us a good understanding of how the brain of a teenager works and it also explains why we sometimes make the decisions we do. The part I have highlighted gives a little information on what we discussed in class.
  •  
    This article is all about how they think that the teen brain hasn't fully developed yet and why. It talks about how every teenage brain is different and how our brains are more vulnerable to addiction which could help me with my teacher for 5 minutes assignment.

Animal Emotions: Exploring Passionate Natures | BioScience | Oxford Academic - 1 views

      This means a type of behaviour related to a species, like mating behaviour for example.
  • My goal is to convince skeptics that a combination of “hard” and “soft” interdisciplinary research is necessary to advance the study of animal emotions.
  • broadly defined as psychological phenomena that help in behavioral management and control
  • Likewise, no single theory of emotions captures the complexity of the phenomena called emotions
  • It is important to extend our research beyond the underlying physiological mechanisms that mask the richness of the emotional lives of many animals and learn more about how emotions serve them as they go about their daily activities
    • Daryl Bambic
       
      Ignore the previous sentence because this one explains it: the study of emotions needs to focus more on how they help us in life and less on the biology of them.

  • B. F. Skinner
    • Daryl Bambic
       
      Skinner was a pioneer in behaviour conditioning. He taught that emotions, because we can't measure them, are not important to understanding behaviour.
  • Why then are there competing views on the nature of animal emotions? In part, this is because some people view humans as unique animals, created in the image of God
  • researchers studying animal behavior came to realize that there was too little in studies of animal emotions and minds that was directly observable, measurable, and verifiable, and chose instead to concentrate on behavior because overt actions could be seen, measured objectively, and verified
  • Most researchers now believe that emotions are not simply the result of some bodily state that leads to an action
  • William James and Carl Lange
  • James and Lange argued that fear, for example, results from an awareness of the bodily changes (heart rate, temperature) that were stimulated by a fearful stimulus.
  • Walter Cannon's criticisms

  • dopamine (and perhaps serotonin and norepinephrine)
  • rats enjoy being playfully tickled.
  • grief in geese
  • grief and depression in orphan elephants is a real phenomeno
  • It is unlikely that romantic love (or any emotion) first appeared in humans with no evolutionary precursors in animals
  • common brain systems and homologous chemicals underlying love that are shared among humans and animals
  • No one discipline will be able to answer all of the important questions that still need to be dealt with in the study of animal emotions
  • However, research that reduces and minimizes animal behavior and animal emotions to neural firings, muscle movements, and hormonal effects will not likely lead us significantly closer to an understanding of animal emotions.
  • All research involves leaps of faith from available data to the conclusions
    • Daryl Bambic
       
      What do you think about this sentence?
  • studies of the behavior of captive animals
  • Field work also can be problematic. It can be too uncontrolled to allow for reliable conclusions to be drawn.
  • behavior is primary; neural systems subserve behavior
  • Emotions are an integral part of human life, so why not for other animals?
  • in many instances, differences in degree rather than differences in kind.
