Theoretical frameworkThis paper aims to highlight why spoken words are so important. The suggested theoretical framework for the functioning of words is presented in the flowchart here. It suggests the bidirectional relationship between* thoughts and emotion* thoughts and words* thoughts and behaviours* emotions and behavioursTo understand this, consider the following example: If someone speaks harsh words to you, then you become angry or offended after hearing those words. Once you experience these emotions, your resulting behaviour are affected i.e. you may talk back to the person, hit the person or leave the room! So if you trace back the series of events that occurred you'll be able to understand the word route till here: Harsh words became angry/hurt emotions and resulted in either talking back or escaping the situation (behaviour). This is one path that the word route may take. However, it is important to understand that words, thoughts, emotions, behaviours and physiological response are not stand alone features and in fact are all connected as proposed in the theoretical framework earlier.Now, it is important to understand when behaviour s become automatic they shape our future. For instance, poor dietary habits may lead one to coronary heart diseases, hypertension and other related diseases. Thereby, I propose that thoughts and words are important because of the lasting effects they may bring upon us by colouring our emotions and shaping our behaviour.Positive thinkingConnection between words and thought: Vygotsky, 1986 as cited by Sebens, 2008 proposed a verbal theory of self-regulation. According to this theory, human beings developed language as a means of communicating their thoughts. Vygotsky suggested that there is a private speech (the internal monologue that an individual has with himseliTherself) and social speech (when they talk to others). In this paper, I first point out the effects of private speech (thoughts).Effect on the Body's Physiology: Gibson, 2012 suggested a link between positive thinking and health. In his literature review, he tried to explain why think link exists. The author posed that positive thinking has a positive effect on health and healing because it influences our body's immune system. He quotes this connection and states that our thoughts impact the physiological state we experience by the prefrontal cortex-amygdala-locus ceruleushypothalamic-pituitary-adrenal axis (Chestnut, 2005 as quoted by Gibson, 2012). Further quoting Chestnut's work, Gibson writes that positive thoughts come from the left prefrontal cortex and promoting homeostatic physiology and inhibiting stress and adaptive physiology via inhibiting the amygdala-locus ceruleushypothalamic-pituitary-adrenal axis, On the other hand, negative thoughts come from the right prefrontal cortex in that case they have the opposite effect as they promoting stress and adaptive physiology, inhibit homeostasis by firing the amygdala-locus ceruleushypothalamic-pituitary-adrenal axis.Either of these pathways can take place depending on our thoughts. So while positive words will inhibit stress, negative thoughts will work in the opposite way and promote stress. These suggested pathways, according to the author, are constantly being stimulated. However, at one time, only one pathway can be activated.Gibson's paper concludes that positive thinking is important for an individual's wellbeing because of its effects on the physiology of the body and especially because of its influence on the cardiovascular and immune system health. The author also suggested that positive thinking benefits short and long term surgery recovery and cancer experience.Use in cognitive behaviour therapy: Cognitive Behaviour Therap, one of the leading therapies of today, works on the same principle. The goal of therapy is to help the client by changing their thinking, behavior and emotional responses. …
