The Orbitofrontal Cortex and Social Behaviors

Each person is a social being and is aware of the environment that they live in. People learn from their experiences as well as from observing others. When children learn about their environment first hand or by observing another, negative and positive behaviors are reinforcement. If a child does a behavior and receives a reward for that behavior, the rewarded behavior is reinforced. Similarly, when someone witnesses negative consequences based on their behavior, they tend to modify that behavior (Schmied & Tully, 2009, p. 9).

The basic assumption of the behaviourist approach is that all behaviour is learned through experiences a person has in their environment. From this we know that behaviourists are on the side of nature in the “nature vs. nurture” debate. In comparison bio psychologists will be firmly on the side of nurture.

The limbic system (or Paleomammalian brain) is a set of brain structures including the hippocampus, amygdala, anterior thalamic nuclei, and limbic cortex, which support a variety of functions including emotion, behavior, long term memory, and olfaction.[1] The term "limbic" comes from Latin limbus, loosely translating as "border" or "belt".

Behaviourists focus on the influence of the environment, they chose not to be concerned with the internal mechanisms that occur inside the organism, they believe that your behaviour depends on what factors are present in the environment at any given time. Another big contributor to this approach is Ivan Pavlov who was made famous for conditioning in which he used dogs in an experiment.

It assumes that the behavior of a human is a result of the individual's past, the example is punishment and anything else. Thus, although behaviorists generally accept the important role of inheritance in determining behavior, they focus primarily on environmental factors.

For my reflection paper, I chose to give my opinion on the NBB’s, short for “Neurological-Based Atypical Behaviors”. NBB is defined as a collection of deeds or the behavior of children that happen outside the usual boundaries of self control.

In addition, the limbic system is responsible for our perception of other emotions, both positive and negative, which explains the mood altering properties of many drugs. The cerebral cortex is divided into areas that control specific functions. Different areas process information from our senses, enabling us to see, feel, hear, and taste. The front part of the cortex, the frontal cortex or forebrain, is the thinking center of the brain, it powers our ability to think, plan, solve problems, and make decisions.

James Fallon, a neuroscientist attending the UC Irvine School of Medicine began reviewing and studying scans of the human brain. Soon enough he began to notice a pattern in the scans of some people who were thought to be psychopaths. In each scan they all appeared to have low levels of activity in a region of the brain located towards its center at the base of the frontal and temporal lobes. This region, called the orbital cortex is involved in regulating our emotions and impulses and also plays a role in morality and

Everyday people use social cognition as a tool to help them thrive in social world. There are many important aspects of social cognition that are helpful to us in making decisions and help us to interpret the world around us. An important aspect that is linked to social cognition is that of thought suppression. Thought suppression is when a person tries to force particular thoughts, memories or feelings out of their minds that may be unpleasant or may cause a great deal of stress for the individual. Many people are unaware how often we use thought suppression in our daily lives, but the truth is we use it in almost every aspect of our day.

The limbic system was first recognized due to Franz Josef Gall (LeDoux, J., 1996). Franz Joseph Gall developed the idea of “phrenology” that focused on the study of the different variations of bumps on the human skull to be related to differences in behavioral and emotional functioning. The limbic system’s main function in the brain is to control emotional behaviors and certain forms of memories that are infused with emotion (amygdala). The amygdala is a part of the brain that forms the tail end of the basal ganglia within the rostral temporal lobe and is located near the hippocampus (Lambert, K.G. & Kinsley, C .H., 2005). The amygdala, as defined by the text, is an almond-shaped structure that functions as a part of the limbic system involved in regulation of emotion and sexual urges (Lambert, K.G. & Kinsley, C .H., 2005). In addition, the amygdala is comprised of a dozen or more sub regions that are not all involved in fear conditioning (LeDoux, J., 1996).

A psychopath is traditionally defined as someone with a personality disorder characterized by persistent antisocial behavior, impaired empathy and remorse, and bold, disinhibited, egotistical traits. In society, psychopaths display specific characteristics such as lack of empathy, which may identify and explain how they respond in certain situations.

This essay will outline and compare both biological and behavioural perspectives on human behaviour. The history, major discoveries and theories will be discussed along with some of the most influential theorists in each of these two areas of psychology. This essay will also compare the two areas strengths and weaknesses in the field of psychology.

In order to understand why people act in antisocial ways, one needs to pinpoint which area of the brain controls social behavior. The prefrontal cortex has been thought to have something to do with control of social behavior ever since Phineas Gage's famous accident in 1848 (1). Phineas Gage was a

The importance of the amygdala in social cognitions has been examined in both primate and human studies. Use of primates to study the social brain suggests that the amygdala contributes to social cognition. Kluver and Bucy made large bilateral lesions in monkey brains made across the amygdala, temporal neocortex, and surrounding structure. After the lesion, the animals engaged in hypersexual behaviors, unusual tameness, and a lack of knowledge about emotional stimuli. Lesions exclusively targeting the monkey’s amygdala resulted in similar, but more subtle impairments. This suggest that the amygdala may play a role in emotions elicited by social cues. Studies of the amygdala’s role in human social cognition suggest that the temporal lobes process socially relevant facial information from humans. Emotions from facial expressions, in particular fear are projected to the amygdala. Studies using FMRI to examine typical subjects and subjects with amygdala damage support this theory. Individuals with amygdala damage have difficulty recognizing facial expressions, specifically negative emotions such as fear.

Whereas the psychodynamic model began looking at the clinical work of physicians the behavioural model began in laboratories experimenting on behavioural conditioning, using stimuli and rewards, observing how their manipulations affected the responses of the individual they were studying. This model unlike the psychodynamic model can be tested and it is because of this that this model holds more weighting than the psychodynamic model when trying to understand ‘abnormal’ behaviour. However this model is not without its weaknesses as there is no evidence that individuals that display ‘abnormal’ behaviour are victims of improper conditioning. Behaviourists would argue that ‘abnormal’ functioning is learnt behaviour, and not environmental or genetic, the
