Cognitive Development during Adolescence
Learning Outcomes
- Explain Piaget’s theory on formal operational thought
- Describe cognitive abilities and changes during adolescence
Adolescence is a time of rapid cognitive development. Biological changes in brain structure and connectivity in the brain interact with increased experience, knowledge, and changing social demands to produce rapid cognitive growth. These changes generally begin at puberty or shortly thereafter, and some skills continue to develop as an adolescent ages. Development of executive functions, or cognitive skills that enable the control and coordination of thoughts and behavior, are generally associated with the prefrontal cortex area of the brain. The thoughts, ideas, and concepts developed at this period of life greatly influence one’s future life and play a major role in character and personality formation.
Perspectives and Advancements in Adolescent Thinking
There are two perspectives on adolescent thinking: constructivist and information-processing. The constructivist perspective, based on the work of Piaget, takes a quantitative, stage-theory approach. This view hypothesizes that adolescents’ cognitive improvement is relatively sudden and drastic. The information-processing perspective derives from the study of artificial intelligence and explains cognitive development in terms of the growth of specific components of the overall process of thinking.
Improvements in basic thinking abilities generally occur in five areas during adolescence:
- Attention. Improvements are seen in selective attention (the process by which one focuses on one stimulus while tuning out another), as well as divided attention (the ability to pay attention to two or more stimuli at the same time).
- Memory. Improvements are seen in working memory and long-term memory.
- Processing Speed. Adolescents think more quickly than children. Processing speed improves sharply between age five and middle adolescence, levels off around age 15, and does not appear to change between late adolescence and adulthood.
- Organization. Adolescents are more aware of their own thought processes and can use mnemonic devices and other strategies to think and remember information more efficiently.
- Metacognition. Adolescents can think about thinking itself. This often involves monitoring one’s own cognitive activity during the thinking process. Metacognition provides the ability to plan ahead, see the future consequences of an action, and provide alternative explanations of events.
Formal Operational Thought
In the last of the Piagetian stages, a child becomes able to reason not only about tangible objects and events, but also about hypothetical or abstract ones. Hence it has the name formal operational stage—the period when the individual can “operate” on “forms” or representations. This allows an individual to think and reason with a wider perspective. This stage of cognitive development, termed by Piaget as formal operational thought, marks a movement from an ability to think and reason from concrete visible events to an ability to think hypothetically and entertain what-if possibilities about the world. An individual can solve problems through abstract concepts and utilize hypothetical and deductive reasoning. Adolescents use trial and error to solve problems, and the ability to systematically solve a problem in a logical and methodical way emerges.

Formal Operational Thinking in the Classroom
School is a main contributor in guiding students towards formal operational thought. With students at this level, the teacher can pose hypothetical (or contrary-to-fact) problems: “What if the world had never discovered oil?” or “What if the first European explorers had settled first in California instead of on the East Coast of the United States?” To answer such questions, students must use hypothetical reasoning, meaning that they must manipulate ideas that vary in several ways at once, and do so entirely in their minds.
The hypothetical reasoning that concerned Piaget primarily involved scientific problems. His studies of formal operational thinking therefore often look like problems that middle or high school teachers pose in science classes. In one problem, for example, a young person is presented with a simple pendulum, to which different amounts of weight can be hung (Inhelder & Piaget, 1958). The experimenter asks: “What determines how fast the pendulum swings: the length of the string holding it, the weight attached to it, or the distance that it is pulled to the side?” The young person is not allowed to solve this problem by trial-and-error with the materials themselves, but must reason a way to the solution mentally. To do so systematically, they must imagine varying each factor separately, while also imagining the other factors that are held constant. This kind of thinking requires facility at manipulating mental representations of the relevant objects and actions—precisely the skill that defines formal operations.
As you might suspect, students with an ability to think hypothetically have an advantage in many kinds of school work: by definition, they require relatively few “props” to solve problems. In this sense they can in principle be more self-directed than students who rely only on concrete operations—certainly a desirable quality in the opinion of most teachers. Note, though, that formal operational thinking is desirable but not sufficient for school success, and that it is far from being the only way that students achieve educational success. Formal thinking skills do not insure that a student is motivated or well-behaved, for example, nor does it guarantee other desirable skills. The fourth stage in Piaget’s theory is really about a particular kind of formal thinking, the kind needed to solve scientific problems and devise scientific experiments. Since many people do not normally deal with such problems in the normal course of their lives, it should be no surprise that research finds that many people never achieve or use formal thinking fully or consistently, or that they use it only in selected areas with which they are very familiar (Case & Okomato, 1996). For teachers, the limitations of Piaget’s ideas suggest a need for additional theories about development—ones that focus more directly on the social and interpersonal issues of childhood and adolescence.
Hypothetical and abstract thinking
One of the major premises of formal operational thought is the capacity to think of possibility, not just reality. Adolescents’ thinking is less bound to concrete events than that of children; they can contemplate possibilities outside the realm of what currently exists. One manifestation of the adolescent’s increased facility with thinking about possibilities is the improvement of skill in deductive reasoning (also called top-down reasoning), which leads to the development of hypothetical thinking. This provides the ability to plan ahead, see the future consequences of an action and to provide alternative explanations of events. It also makes adolescents more skilled debaters, as they can reason against a friend’s or parent’s assumptions. Adolescents also develop a more sophisticated understanding of probability.
This appearance of more systematic, abstract thinking allows adolescents to comprehend the sorts of higher-order abstract logic inherent in puns, proverbs, metaphors, and analogies. Their increased facility permits them to appreciate the ways in which language can be used to convey multiple messages, such as satire, metaphor, and sarcasm. (Children younger than age nine often cannot comprehend sarcasm at all). This also permits the application of advanced reasoning and logical processes to social and ideological matters such as interpersonal relationships, politics, philosophy, religion, morality, friendship, faith, fairness, and honesty.
Metacognition
Metacognition refers to “thinking about thinking.” It is relevant in social cognition as it results in increased introspection, self-consciousness, and intellectualization. Adolescents are much better able to understand that people do not have complete control over their mental activity. Being able to introspect may lead to forms of egocentrism, or self-focus, in adolescence. Adolescent egocentrism is a term that David Elkind used to describe the phenomenon of adolescents’ inability to distinguish between their perception of what others think about them and what people actually think in reality. Elkind’s theory on adolescent egocentrism is drawn from Piaget’s theory on cognitive developmental stages, which argues that formal operations enable adolescents to construct imaginary situations and abstract thinking.
Accordingly, adolescents are able to conceptualize their own thoughts and conceive of other people’s thoughts. However, Elkind pointed out that adolescents tend to focus mostly on their own perceptions, especially on their behaviors and appearance, because of the “physiological metamorphosis” they experience during this period. This leads to adolescents’ belief that other people are as attentive to their behaviors and appearance as they are of themselves. According to Elkind, adolescent egocentrism results in two distinct problems in thinking: the imaginary audience and the personal fable. These likely peak at age fifteen, along with self-consciousness in general.
Imaginary audience is a term that Elkind used to describe the phenomenon that an adolescent anticipates the reactions of other people to them in actual or impending social situations. Elkind argued that this kind of anticipation could be explained by the adolescent’s preoccupation that others are as admiring or as critical of them as they are of themselves. As a result, an audience is created, as the adolescent believes that they will be the focus of attention.
However, more often than not the audience is imaginary because in actual social situations individuals are not usually the sole focus of public attention. Elkind believed that the construction of imaginary audiences would partially account for a wide variety of typical adolescent behaviors and experiences; and imaginary audiences played a role in the self-consciousness that emerges in early adolescence. However, since the audience is usually the adolescent’s own construction, it is privy to their own knowledge of themselves. According to Elkind, the notion of imaginary audience helps to explain why adolescents usually seek privacy and feel reluctant to reveal themselves–it is a reaction to the feeling that one is always on stage and constantly under the critical scrutiny of others.
Elkind also addressed that adolescents have a complex set of beliefs that their own feelings are unique and they are special and immortal. Personal fable is the term Elkind created to describe this notion, which is the complement of the construction of imaginary audience. Since an adolescent usually fails to differentiate their own perceptions and those of others, they tend to believe that they are of importance to so many people (the imaginary audiences) that they come to regard their feelings as something special and unique. They may feel that only they have experienced strong and diverse emotions, and therefore others could never understand how they feel. This uniqueness in one’s emotional experiences reinforces the adolescent’s belief of invincibility, especially to death.
This adolescent belief in personal uniqueness and invincibility becomes an illusion that they can be above some of the rules, disciplines and laws that apply to other people; even consequences such as death (called the invincibility fable). This belief that one is invincible removes any impulse to control one’s behavior (Lin, 2016). [1] Therefore, adolescents will engage in risky behaviors, such as drinking and driving or unprotected sex, and feel they will not suffer any negative consequences.

Intuitive and Analytic Thinking
Piaget emphasized the sequence of thought throughout four stages. Others suggest that thinking does not develop in sequence, but instead, that advanced logic in adolescence may be influenced by intuition. Cognitive psychologists often refer to intuitive and analytic thought as the dual-process model; the notion that humans have two distinct networks for processing information (Kuhn, 2013.) [2] Intuitive thought is automatic, unconscious, and fast, and it is more experiential and emotional.
In contrast, analytic thought is deliberate, conscious, and rational (logical). While these systems interact, they are distinct (Kuhn, 2013). Intuitive thought is easier, quicker, and more commonly used in everyday life. As discussed in the adolescent brain development section earlier in this module, the discrepancy between the maturation of the limbic system and the prefrontal cortex, may make teens more prone to emotional intuitive thinking than adults. As adolescents develop, they gain in logic/analytic thinking ability and sometimes regress, with social context, education, and experiences becoming major influences. Simply put, being “smarter” as measured by an intelligence test does not advance cognition as much as having more experience, in school and in life (Klaczynski & Felmban, 2014). [3]
Risk-taking
Because most injuries sustained by adolescents are related to risky behavior (alcohol consumption and drug use, reckless or distracted driving, and unprotected sex), a great deal of research has been done on the cognitive and emotional processes underlying adolescent risk-taking. In addressing this question, it is important to distinguish whether adolescents are more likely to engage in risky behaviors (prevalence), whether they make risk-related decisions similarly or differently than adults (cognitive processing perspective), or whether they use the same processes but value different things and thus arrive at different conclusions. The behavioral decision-making theory proposes that adolescents and adults both weigh the potential rewards and consequences of an action. However, research has shown that adolescents seem to give more weight to rewards, particularly social rewards, than do adults. Adolescents value social warmth and friendship, and their hormones and brains are more attuned to those values than to long-term consequences (Crone & Dahl, 2012). [4]
Some have argued that there may be evolutionary benefits to an increased propensity for risk-taking in adolescence. For example, without a willingness to take risks, teenagers would not have the motivation or confidence necessary to leave their family of origin. In addition, from a population perspective, there is an advantage to having a group of individuals willing to take more risks and try new methods, counterbalancing the more conservative elements more typical of the received knowledge held by older adults.
Relativistic Thinking
Adolescents are more likely to engage in relativistic thinking—in other words, they are more likely to question others’ assertions and less likely to accept information as absolute truth. Through experience outside the family circle, they learn that rules they were taught as absolute are actually relativistic. They begin to differentiate between rules crafted from common sense (don’t touch a hot stove) and those that are based on culturally relative standards (codes of etiquette). This can lead to a period of questioning authority in all domains.
As we continue through this module, we will discuss how this influences moral reasoning, as well as psychosocial and emotional development. These more abstract developmental dimensions (cognitive, moral, emotional, and social dimensions) are not only more subtle and difficult to measure, but these developmental areas are also difficult to tease apart from one another due to the inter-relationships among them. For instance, our cognitive maturity will influence the way we understand a particular event or circumstance, which will in turn influence our moral judgments about it, and our emotional responses to it. Similarly, our moral code and emotional maturity influence the quality of our social relationships with others.
