      This is the key idea behind the KETO diet; eat very little sugar and carbs so the insulin levels drop and the body burns fat for energy.

  • Obesity is a leading cause of death worldwide.
  • Exercise increases cardiovascular capacity, lowers blood pressure, and helps improve diabetes, joint flexibility, and muscle strength (American Heart Association, 1998). Exercise also slows the cognitive impairments that are associated with aging (Kramer, Erickson, & Colcombe, 2006).

  • Between 3% and 4% of men are gay, and between 1% and 2% of women are lesbian
  • The Canadian Psychological Association issued a policy statement in February 1982 endorsing the principle that there be no discrimination on the basis of sexual orientation for (a) recruitment; (b) hiring; (c) salary; (d) promotion rate; (e) fringe benefits; or (f) assignment of duties. The American Psychiatric Association no longer considers homosexuality to be a mental illness, although it did so until 1973.

      This is a good example of sociological influences on the diagnosis and understanding of mental illness. This 'mental illness' was ousted from the DSM in 1973. You can read more here: https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4695779/

  • 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
      Daryl Bambic on 22 Oct 21
       
      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
  • there is a mental component that does not have to follow a bodily reaction
  • drugs producing bodily changes like those accompanying an emotional experience

  • current research (LeDoux 1996) indicates that all emotions are not necessarily packaged into a single system, and there may be more than one emotional system in the brain.

      Ethology is the study of animal behaviour and mind
  • cognitive ethologists want to know what it is like to be another animal.
  • concerns how emotions and cognition are linked
  • A sense of self in the act of knowing is created,
  • various brain structures map both the organism and external objects
  • I am inclined merely to delete it [the mental realm] from biological explanation, because it is an entirely private phenomenon, and biology must deal with the publicly demonstrable.”
  • abanac postulated that the first mental event to emerge into consciousness was the ability of an individual to experience the sensations of pleasure and displeasure
  • Examples of animal emotions
  • Social play
  • Studies of the chemistry of play support the idea that play is enjoyable.
  • 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

      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.

      "Research demonstrates"...what is wrong with this? Can we know how this study was conducted? What were the variables? Was it correlation or causation?

  • collect and interpret data in their everyday lives
  • accepting explanations for events without testing them thoroughly may lead us to think that we know the causes of things when we really do not.
  • Empirical methods include the processes of collecting and organizing data and drawing conclusions about those data

  • Statements that cannot be objectively measured or objectively determined to be true or false are not within the domain of scientific inquiry

  • Even laboratory mice experience a similar phase during their development.

  • Teens also can play games that require them to make choices,
  • 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.
  • eel good” response helps explain why they often give in to impulsive desires.
  • to be shouting louder” between the ages of 13 and 17 than at any other time during human development.
  • prefrontal cortex, it’s the brain’s master planner.
  • 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.
