CQ: Communication Quotient™ the measure of an individual's CI: Communication Intelligence™ , bridging the domains of Intellectual Quotient (IQ) and Emotional Quotient (EQ). CI: Communication Intelligence™ involves the cognitive and affective aspects of communication, and it refers to an individual's ability in expressing thoughts, emotions, desires, needs and information.
The development of CQ  as a theory and concept can be traced back to the challenges posed to the notion of IQ as the sole explanation of cognitive abilities. In 1983, Howard Gardner's Theory of Multiple Intelligences (Gardner, 1983) questioned the sufficiency of traditional intelligence measures in explaining cognitive capacity.
The human brain possesses a remarkable ability to be aware of emotions and engage in verbal thinking. This unique characteristic allows for the simulation of various options and consideration of which behaviors would yield the best outcomes.Language plays a pivotal role as it serves as a bridge between individuals' intellectual quotient (IQ) and emotional quotient (EQ).
Intelligence Quotient (IQ) is a standardized measurement of cognitive intelligence that assesses a person's intellectual abilities across various domains (Neisser et al., 1996). It measures skills such as reasoning, problem-solving, logical thinking, memory, and verbal comprehension. IQ tests are designed to provide a numerical score that indicates an individual's relative intelligence compared to the general population.
Emotional Quotient (EQ) is standardized measurement of emotional intelligence, which refers to their ability to recognize, understand, and manage their own emotions, as well as their ability to perceive and empathize with the emotions of others (Goleman, 1995). EQ encompasses skills such as self-awareness, self-regulation, social awareness, and relationship management. It provides insights into an individual's capacity to handle emotional challenges and navigate interpersonal interactions effectively.
