    The Four Fundamental Causes

    This post is an ambitious attempt to link the four causes delineated by Aristotle, to the four questions asked by Tinbergen to the four types of explanations that can be made for any human/animal ability. First a bit of a background. Aristotle had listed four causes - Material,  Efficient, Formal and Final causes. From the Wikipedia: Aristotle held that there were four kinds of causes: A thing's ...

    The Eight Rasas/Emotions (contd)

    In the last post we looked at the eight Rasas and how they are related to the eight color terms and the eight basic emotions.   Another list of basic emotions follows from the work of Carroll Izard; Izard is interested in the infants facial expressions and believes that due to lack of socialization etc there is perfect concordance between the infants facial expressions and infants emotional...

    Basic Emotions

    This post is an attempt to get to the basic emotions. Regular readers of this blog will readily appreciate when I claim that there are eight basic emotions and that they follow a developmental/evolutionary time-course and follow a  particular order.   First let us review the attempts made till now to classify and identify the basic emotions- foremost amongst them is the tradition of Tomkins and ...

  • The Eight Rasas (aesthetic essences)

    According to Indian Aesthetics , as outlined in Bharat Muni's Natyashatra,  there are eight Rasas or impacts that an aesthetic piece of work like dance form/ literary piece, tries to achieve/invoke in the beholder/reader. These can be loosely thought of as eight different kinds of aesthetic experiences.   As is evident I like all things eight, as I believe they have an underlying eight fold evo-devo st...

  • Schizophrenia: 4 a's and ABCD

    The term Schizophrenia , as many of the readers will recall, was coined by Eugen Bleuler, a Swiss psychiatrist , who  intended the 'split personality' to reflect the fact that there was an underlying dissociation between various functions like memory, cognition, emotion that are normally integrated in normal people. He also gave the famous 4 a's that he presumed lied at the core of the schizophrenia and were ...

  • Buddha's Brain

    I recently came across an authors@google talk by Rick Hanson, who is the author of 'Buddha's Brain:  the practical neuroscience of happiness, love and wisdom' and was immediately drawn by the similarity of the framework he uses and my ABCD model. Rick draws a lot from the Buddhist tradition and its humbling to find many similarities between what buddha preached thousands of years ago and what neuroscience tell ...

  • The four mechanisms of evolution

    Regular readers of the blog will know of my enthusiasm for evolutionary and developmental theories especially the eight stage evo-devo theory. I have also advocated the four primary problems faced by all creatures undergoing evolution, as delineated by Theodore Millon- the problems of Existence; Adaptation; Replication and Abstraction which lead to polarities of pain/pleasure;  active/passive; self/other and ...

  • Dopamine: prediction-error vs. incentive salience

    The exact role that dopamine plays in learning remains controversial; some think it acts as a prediction error signal, while Berrdige et al believe that dopamine codes for incentive salience.   A recent paper throws some light on the issue. It uses a  simple Pavlovian conditioning paradigm. To recap, US and CS are paired and after some time CS starts predicting the reward ; however the twist ...

    My name is Beliz Hazan.Having graduated from the
    psychology department of Ege University with
    a bachelor’s degree in psychology in July 2006, I have developed a
    strong interest in psychological research, particularly in
    experimental psychology. During my undergradute studies, I found the
    chance of taking courses on perception, psychology of learning,
    experimental psychology, research methods and psychometry. In
    September 2006, I was admitted to Hacettepe University as it is highly
    reputed for its medical school and its experimental programmes. The
    MSc programme in experimental psychology lasted 3 years, from 2006
    until 2009, including one year of taught programme and two years of
    research. The title of my master thesis was Comparison of the
    cognition,meta-cognition and personal features in patients with
    psychophsiological insomnia, paradoxical insomnia and healthy people.
    In my thesis I applied 7 neuropsychological tests including two
    meta-memory tasks. Now I am studying in the PhD program of Cognition, Brain and Behavior subprogram at Brooklyn College in City University of New York.

    In the frame of this program I am attending too the Class of Cognitive Psychology. For this week we had a homework about the article of Chomsky on Skinner’s theory. I had an opportunity to read you article also. Thank you. It was very beneficial for me in terms of understanding the original article.

    Thank you again.
