The ‘Triune Brain’ theory by Neuroscientist Paul MacLean — an evolutionary perspective

The Concept of the "Triune Brain"

In the 1960s, American neuroscientist Paul MacLean formulated the ‘Triune Brain’ model, which is based on the division of the human brain into three distinct regions. MacLean’s model suggests the human brain is organized into a hierarchy, which itself is based on an evolutionary view of brain development. The three regions are as follows:

  1. Reptilian or Primal Brain (Basal Ganglia)
  2. Paleomammalian or Emotional Brain (Limbic System)
  3. Neomammalian or Rational Brain (Neocortex)

At the most basic level, the brainstem (Primal Brain) helps us identify familiar and unfamiliar things. Familiar things are usually seen as safe and preferable, while unfamiliar things are treated with suspicion until we have assessed them and the context in which they appear. For this reason, designers, advertisers, and anyone else involved in selling products tend to use familiarity as a means of evoking pleasant emotions.

The Psychology of Gossiping – in a snapshotThe Psychology of Gossiping – in a snapshot

Gossiping is a universal social behaviour that involves the giving and receiving of information about others, generally perceived as having a negative effect on social groups and it is commonly sensationalistic in manner. The psychology of gossiping encompasses various aspects of human behaviour, including social interaction, communication, and interpersonal relationships.

Gossiping serves several psychological functions, such as forming and maintaining social bonds, establishing group norms, and conveying social information. Understanding the psychology of gossiping requires an examination of the underlying motivations, cognitive processes, and social dynamics involved in this behaviour.

One of the primary psychological functions of gossiping is its role in social bonding. According to evolutionary psychologists, gossiping may have evolved as a mechanism for monitoring and regulating social relationships within groups. By sharing information about others, individuals can establish and reinforce alliances, as well as identify potential threats or allies within their social networks. Gossiping also serves as a form of social currency, allowing individuals to exchange information and build rapport with others.

Furthermore, gossiping can be driven by intrinsic motivations related to curiosity and entertainment. People are naturally drawn to stories about others, particularly those involving conflict, romance, or scandal. This inclination toward sensationalistic narratives reflects the human tendency to seek novelty and emotional arousal through storytelling. From a psychological perspective, gossiping can be seen as a means of satisfying these innate cognitive and emotional needs.

In addition to its role in social bonding and entertainment, gossiping serves as a mechanism for transmitting social information and enforcing group norms. Through gossip, individuals communicate expectations and judgements regarding behaviour, values, and social roles within their communities. Gossip can function as a form of informal social control by publicly sanctioning or condemning certain behaviours, thereby influencing the conduct of group members.

The psychology of gossiping involves considerations of ethical and moral implications. While gossip can facilitate social cohesion and information sharing, it can also lead to negative consequences such as reputational damage, interpersonal conflict, disharmony, and breaches of privacy. Understanding the psychological mechanisms underlying gossiping can shed light on the ethical dilemmas associated with this behaviour and inform strategies for promoting responsible communication within social contexts.

Gossiping can indeed be malicious, as it involves spreading rumors or information about others that may be harmful, untrue, or damaging to their reputation. Malicious gossip can have serious consequences for the individuals involved, leading to damaged relationships, loss of trust, and even psychological harm. It is important to understand the impact of malicious gossip and the ethical considerations surrounding the spread of such information.

Malicious gossip is often driven by negative intentions, such as jealousy, resentment, or a desire to harm someone’s reputation. It can take various forms, including spreading false information about an individual’s personal life, career, or character. In some cases, malicious gossip may be used as a tool for bullying or manipulation, with the intent to undermine someone’s social standing or credibility.

The effects of malicious gossip can be far-reaching. It can lead to strained relationships, social ostracism, and damage to one’s professional reputation. In extreme cases, it can even result in legal action if the spread of false information causes tangible harm to an individual’s livelihood or well-being.

In summary, the psychology of gossiping encompasses various psychological functions, including its role in social bonding, entertainment, information transmission, and norm enforcement. By examining the underlying motivations, cognitive processes, and social dynamics involved in gossiping, researchers can gain insights into the complexities of human social behavior and interpersonal communication.

Polyvagal Theory and Trauma – Dr. Stephen PorgesPolyvagal Theory and Trauma – Dr. Stephen Porges

Stephen Porges, psychiatry professor and researcher, on the polyvagal theory he developed to understand our reactions to trauma:

[Paraphrased] Polyvagal theory articulates three branches of the autonomic nervous system (ANS) that evolved from primitive vertebrates to mammals. First, there is a system known as ‘freeze’, which involves death feigning or immobilisation. Second, the ANS has a ‘fight or flight’ system, which is a mobilisation system. And third, with mammals, there is what Porges calls, a social engagement system (SES), which can detect features of safety, and actually communicate them to another. The SES may also be referred to by some as ‘rest and digest’, which Porges theory suggests is a function of the Vagus Nerve – the tenth cranial nerve, a very long and wandering nerve that begins at the medulla oblongata. When an individual experiences feelings of safety (within an SES state), the autonomic nervous system can support health restoration. In terms of dealing with a life threat, an ordinary person will most likely go into a feigning death, dissociative state of ‘freeze’.

Polyvagal theory in psychotherapy offers emotional co-regulation as an interactive process between therapist and client which engages the social engagement system of both therapist and client. Social engagement provides experiences of safety, trust, mutuality and reciprocity in which we are open to receiving another person, just as they are.

Polyvagal theory has made inroads into medical and psycho-therapeutic treatment, but how should it inform how people treat each other?


“When we become a polyvagal-informed society, we’re functionally capable of listening to and witnessing other people’s experiences, we don’t evaluate them. Listening is part of co-regulation: we become connected to others and this is what I call our biological imperative. So when you become polyvagal-informed you have a better understanding of your evolutionary heritage as a mammal. We become aware of how our physiological state is manifested, in people’s voices and in their facial expression, posture and basic muscle tone. If there’s exuberance coming from the upper part of a person’s face, and their voice has intonation modulation or what’s called prosody, we become attracted to the person. We like to talk to them – it’s part of our co-regulation.

So when we become polyvagal-informed, we start understanding not only the other person’s response but also our responsibility to smile and have inflection in our voice, to help the person we’re talking to help their body feel safe.”
