The Tri-Anthropo-Type Paschalidis Model is a neurobiological Model with psychosocial interpretations. And not only that. The Model translates the neurobiology of behaviour and connects the function of the brain with the personality, the behaviour, the ways of perception, the management and action, the emotional and biological functions [1].

According to the Tri-Anthropo-Type Paschalidis Model, everyone belongs to only one of three distinct Personality Types – the Types A, B or C, which are mainly differentiated by the function and plasticity of their brain. The three Personality Types are classified on the basis of specific neuroanatomical, neurochemical, and physiological characteristics, as well as of specific personality characteristics – traits, which are genetically determined and are inherited from one’s biological parents [1]. The three Personality Types are determined by individual differentiation in the activation, volume and functional connection of the temporal lobe, the amygdala and the hippocampus [1] [2].

The knowledge of each person’s Personality Type promotes the self-knowledge and hetero-knowledge, the mental-psychological and physical health. Training based on the Tri-Anthropo-Type Paschalidis Model gives each and everyone the opportunity to learn the part(s) of the brain they function with, their psychological traits, their behaviour and action. The Tri-Anthropo-Type Paschalidis Model enables each and everyone to achieve personal development and growth, to develop their own “unique” self so that each becomes a “distinct” personality, and to build harmonious happy relationships with the “others” [3].

Having recognized our Type and using our thought as a tool, we can now influence – change the structure of our brain and create new synapses among the three structures of the limbic system – the temporal lobe, the amygdala and the hippocampus. Through this process, we create new pathways of healthy thinking and healthy emotions in order to form a new character: the character of a free person liberated from the restraints of his/her Type [4].

George Paschalidis’ research showed that:

Type A individuals process stimuli with the temporal lobe. They are visual, practical, spontaneous, they process information instantaneously, and they consequently act and react swiftly – at lightning speed. The neurotransmitter serotonin plays the most significant role in Type A individuals: when it is at low levels, it makes them fast and effective, whereas, when it reaches high levels, it causes panic reactions, irritability and extreme hastiness leading to negative results. Haste and tension give them agility enabling them to easily overcome obstacles and make them practical, confident, and perceptive. Their inner tension makes them spontaneous and forces them to act and take risks. It makes them impatient and quick-tempered [5].

Type B individuals process stimuli with the amygdala. They are auditory, analytical, careful, patient, with high self-control and a strong sense of responsibility toward fulfilling their goals, they process information successively, which is why they are cautious in action. For Type B individuals, the neurotransmitter dopamine plays the most important role: when it is at low levels, it allows the person to take action, but, when it reaches high levels, it leads to repetitive thinking, which hinders action. Type B individuals tend to suffer from anxiety; they worry about the future and procrastinate. Their tendency to worry and their fear(s) make them particularly careful. They seldom take the wrong decision, since they seldom take risks [5].

Type C individuals process stimuli with the hippocampus. They are kinesthetic, they process information with persistence, passion, and attention to detail, and persist in accomplishing their targets. They are systematic, innovators, hard workers, stubborn and perfectionists. They have the ability to realize their goals. Action in Type C individuals is determined by the simultaneous function of both serotonin and dopamine. When serotonin and dopamine are in the correct and sufficient quantity in the hippocampus, Type C individuals are led to calm, swift and efficient action. However, high levels of these hormones force them to behave and act with stubbornness and inflexibility. They recall past traumatic experiences and have obsessive behaviour. They are highly demanding persons and want to impose their opinions, views, ideas – even their rules – on others. They never abandon a problematic situation [5]
