Introduction

Humans are sociable creatures by nature. The majority of a person's decisions and behaviours are influenced by other people. Because our brain structure and behaviour are continually affected by our social experiences and social learning, social influence processing is a crucial neurobiological and psychological function. Importantly, we not only learn through direct social experiences or observations, but we are also very vulnerable to other people's expectations, i.e. social norms. Processes of social adaptation are of great interest in a variety of fields, ranging from psychology, medicine, sociology, political science, and marketing to basic everyday activities like communicating with one another in person or virtually, due to the extensive impact of social influence on our behaviour. The neurobiological processes that underpin social influence processing and social adaptation are entrenched in our value and reward systems, and they serve as essential motivators and behaviour drivers. In other words, we control our conduct through inferring value from one another and absorbing social reward cues. As a result, social influence processing is a complex interplay of our motivational, emotional, and cognitive processes, all of which are changed by our interactions with others and shaped by our social experiences. Any disruption in one of these systems can have a negative impact on social functioning. One of the most noticeable and debilitating elements of numerous mental diseases is impairments in social cognition and interpersonal problems. Importantly, the quality and quantity of interpersonal interactions have an influence on both mental and physical health, since they are connected to morbidity and death. Social impact has been researched extensively in a number of fields, having a lengthy history in the social sciences. Modern social neuroscience methods and techniques, such as computational accounts and brain imaging techniques, have recently become more widely used, contributing to a better understanding of the neurobiological mechanisms underlying social influence processing. However, there are still some significant gaps in our understanding. Despite its significant significance for psychiatry, the neuropharmacology of social adaptation mechanisms has received little research thus far, despite its high relevance for psychiatry. While some neurotransmitters and neuropeptides, such as Dopamine (DA) and Oxytocin (OXY), have been shown to influence social adaptation processes, the 5-HT system is central to social cognition. Its significance in social influence processing, however, is not fully recognized. Serotonergic psychedelics, such as Lysergic Acid Diethylamide (LSD) or Psilocybin (Psi), effect on the brain by activating 5-HT2A receptors and modulating emotion mechanisms. And self-relevance processing, providing a unique opportunity they have been demonstrated to affect social cognition and suggestibility, as well as brain activity and connections in the Medial Prefrontal Cortex (mPFC), a region that is heavily engaged in social information processing. The relevance of the 5-HT system in social influence processing is highlighted in this review, which covers recent research on the computational and neurochemical basis of the process. We combine these findings with data from psychedelic research on social cognition to uncover new information about the 5-HT2A system's function in social influence processing. Computational frameworks such as "predictive coding" and neuroimaging results aid in providing a more comprehensive interpretation of the underlying neurobiological mechanisms, particularly the role of the 5-HT system in distinct components of social adaptation such as social information integration processing and value-based decision making. We give a theoretical backdrop and evaluate literature on basic mechanisms of social adaptation and learning in the first half of the paper. We then review more recent findings from social neuroscience and neuro pharmacological studies in order to gain a better understanding of the involved neuronal networks and underlying neuro pharmacological mechanisms of important distinct components in social adaptation processing using this theoretical framework. Furthermore, findings from psychedelic research which are primarily based on studies using psilocybin and LSD to investigate the role of the 5-HT2A receptor not only contribute to a more differentiated understanding of social influence processing, but also extend our knowledge by demonstrating how central processes of social adaptation are interrelated, such as the process of social information integration with the formation of a coherence. Social learning and adaptability mechanisms from an evolutionary standpoint, the capacity to adapt is critical for every species' survival, and it is acquired through the acquisition of skills. The capacity to learn from one another through social interactions encouraged the development of adaptive capabilities in humans and shaped the flexibility of the human social brain. Being able to influence others is the cornerstone of social learning, which is essential for survival, successful social interactions, and adaptive value-based decision making. Furthermore, it has been underlined that the processing and integration of social information is critical for the creation of one's own self-representation, beliefs, and self-awareness. Social alignment is an idea that has been around for a long time. The notion of social alignment is based on people's natural desire to be socially linked and comply. Social alignment is necessary for communicating and learning from one another, and it fosters a sense of belonging. Social alignment mechanisms facilitate social connection and involvement by establishing a shared reality and minimizing unpredictable social contexts, and they also serve as the foundation for adaptation and learning in general. In all sorts of social interactions, social alignment incorporates multi-level, dynamic, and interactive systems that underpin the sharing and inferring of people's mental representations. As part of social alignment, there is social conformity. Societal conformity has been defined as the process of modifying one's attitudes, beliefs, or behaviours to meet social standards that are implicitly or overtly held by a group of people. Various factors for social conformity have been proposed over the long history of social influence study
