Definition of Cognition: The term "cognition" refers to the act of knowing or perceiving, encompassing processes such as understanding, thinking, analyzing, and problem-solving in daily life.
There are four main approaches to studying cognition:
1. Piagetian Approach: Focuses on qualitative changes in thought processes.
2. Information-Processing Approach: Investigates the sequential steps involved in how adolescents receive, perceive, remember, and utilize information.
3. Neurological Approach: Examines cognitive patterns related to the developing brain.
4. Psychometric Approach: Measures quantitative changes in intelligence.

Jean Piaget: Renowned for his work on cognitive development, proposing four major stages:
- Sensorimotor Stage (Birth to age 2): Infants learn through sensory-motor actions. They develop from a self-centered perception to an object-oriented world.
- Preoperational Stage (Ages 2-7): Children gain language and manipulation of symbols but struggle with logic. Characteristics include egocentrism, animism, and transductive reasoning.
- Concrete Operational Stage (Ages 7-11): Logical reasoning with concrete concepts develops; children can classify objects and understand conservation.
- Formal Operational Stage (Ages 12 and beyond): Ability to think abstractly and systematically, forming hypotheses and testing them, resembles junior scientists.

Learning involved mastery of sensory-motor sequences. Transition to symbolic thought occurs later in this stage.

Children engage in symbolic play but are limited by egocentrism and transductive reasoning.
Egocentrism: Difficulty understanding perspectives other than their own.
Transductive Reasoning: Making connections between unrelated events (e.g., a child thinking that because they had a sore throat while combing their hair, combing might cause illness).

Children develop logical reasoning, albeit limited to concrete situations. Can comprehend hierarchies and class inclusion.
Learn conservation, understanding that quantity is not altered by shape change.

Adolescents apply systematic planning and hypothetico-deductive reasoning. Piaget's Pendulum Problem demonstrated this stage.
- Involves testing factors affecting pendulum swing, revealing systematic strategic thinking.

Adolescents develop the capacity for reflective thinking, increasing their moral reasoning and critical evaluation of the adult world.
- This often leads to idealistic attitudes and sometimes motivates teen engagement in social issues.

Adolescents may express high ideals but may struggle to enact them in daily life due to a gap between theory and practice.

Term describing the propensity of adolescents to overcomplicate simple problems due to their developing cognitive abilities.

Development of an imaginary audience and personal fable. Adolescents often feel scrutinized and view their experiences as unique. This can lead to heightened self-consciousness.
- Imaginary Audience: Belief that others are as focused on them as they are on themselves.
- Personal Fable: Belief in the uniqueness of one’s experiences, which can sometimes lead to risky behavior.

Epistemic reasoning evolves from a naïve realist view of information to a more relativistic understanding, eventually moving towards evaluative reasoning where some knowledge is considered more valid than others.

Brain structure maturation continues into the mid-twenties, influencing cognitive development through:
- Increases in the number of myelinated neurons, enhancing processing speed and cognitive function.
- Continued development of frontal lobes related to executive functions, impulse control, and decision-making.
- The amygdala matures faster than the frontal lobes, explaining some emotional and impulsive behaviors seen in adolescents.

Intelligence can be defined variously, with numerous theories:
- Spearman's g theory: A single underlying general intelligence.
- Cattell's fluid and crystallized intelligence: Fluid intelligence being problem-solving ability in novel situations, and crystallized intelligence being the knowledge gained through experience.
- Sternberg's Triarchic Theory: Proposes three types of intelligence: analytical, creative, and practical.
- Gardner's Multiple Intelligences: Identifies various modes, including linguistic, spatial, logical-mathematical, and interpersonal intelligences among others.

Standardized Testing: Primarily through IQ tests, which have been criticized for biases and their narrow focus on certain aspects of intelligence. They often reflect a blend of cognitive ability and knowledge.
Achievement Tests: Measure mastery of content but can also inadvertently reflect intelligence, creating overlap in capabilities assessed.
Use caution in interpreting test scores as they may be influenced by external factors such as emotional state and socio-cultural bias.
