Curiosity no relation observation
Curiosity (from Latin cūriōsitās, from cūriōsus "careful, diligent, curious", akin to cura "care") is a quality related to inquisitive thinking such as exploration, investigation, and learning, evident by observation in humans and animals. Curiosity is heavily associated with all aspects of human development, in which derives the process of learning and desire to acquire knowledge and skill.The term curiosity can also be used to denote the behavior or emotion of being curious, in regard to the desire to gain knowledge or information. Curiosity as a behavior and emotion is attributed over millennia as the driving force behind not only human development, but developments in science, language, and industry.Optimal-arousal theory
Optimal-arousal theory developed out of the need to explain the desire for some to seek out opportunities to engage in exploratory behaviors without the presence of uncertain or ambiguous situations. Optimal-arousal theory attempts to explain this aspect of curiosity by suggesting that one can be motivated to maintain a pleasurable sense of arousal through these exploratory behaviors.
The concept of optimal-arousal of curiosity suggests that there is a tendency to maintain an optimal level of arousal. When a stimulus is encountered that is associated with complexity, uncertainty, conflict, or novelty, this will increase arousal, and exploratory behavior is employed to learn about that stimulus and thereby reduce arousal again. In contrast, if the environment is boring and lacks excitement, arousal is reduced and exploratory behavior will be engaged in order to increase information input and stimulation, and thereby increasing arousal again. This theory addresses both curiosity elicited by uncertain or unfamiliar situations and curiosity elicited in the absence of such situations.Role of neurological aspects and structures
Although the phenomenon of curiosity is widely regarded, its root causes are relatively unknown beyond theory. However, recent studies have provided some insight into the neurological mechanisms that make up what is known as the reward pathway which may impact characteristics associated with curiosity, such as learning, memory, and motivation. Due to the complex nature of curiosity, research that focuses on specific neural processes with these characteristics can help create a better understanding of the phenomenon of curiosity as a whole. The following are characteristics of curiosity and their links to neural aspects that can be thought of as essential in creating exploratory behaviors.Nucleus accumbens
The nucleus accumbens is a formation of neurons and is important in reward pathway activation. As previously mentioned, the reward pathway is an integral part in the induction of curiosity. The release of dopamine in investigating response to novel or exciting stimuli. The fast dopamine release observed during childhood and adolescence is important in development, as curiosity and exploratory behavior are the largest facilitators of learning during early years.
In addition, the sensation pleasure of "liking" can occur when opioids are released by nucleus accumbens. This helps someone evaluate the unfamiliar situation or environment and attach value to the novel object. These processes of both wanting and liking play a role in activating the reward system of the brain, and perhaps in the stimulation of curious or information-seeking tendencies as well.Attention
Attention is important to the understanding of curiosity because it directly correlates with one's abilities to selectively focus and concentrate on particular stimuli in the surrounding environment. As there are limited cognitive and sensory resources to understand and evaluate various stimuli, attention allows the brain to better focus on what it perceives to be the most important or relevant of these stimuli. Individuals tend to focus their energies on stimuli that are particularly stimulating or engaging. Indicating that the more attention a stimulus garners, the more frequent one's energy and focus will be directed towards that stimulus. This idea suggests an individual will focus their attention on new or unfamiliar stimuli in an effort to better understand or make sense of the unknown over the more familiar or repetitive stimuli, creating the idea that curiosity demands attention.State and trait curiosity
There are two distinct classifications of types of curiosity: state and trait curiosity. Both types determine whether curiosity comes from within or outside of a person. State curiosity is external such as wondering why things happen for the sake of just curiousness, for example, wondering why most stores open at 8 a.m. This type of curiosity tends to be the most relatable for people on a day-to-day basis since state curiosity relates to high levels of reward. On the other hand, trait curiosity relates to people who are interested in learning. Generally, it could be trying out a new sport or food, or traveling to a new unknown place. One can look at curiosity as the urge that draws people out of their comfort zones and fears as the agent that keeps them within those zones.
