Study Notes

Physical & Cognitive Development in Adolescence

Adolescence is typically defined as beginning with puberty and ending when individuals are considered adults.
The common understanding of when adolescence starts is around age 12.
Physical development during adolescence has changed over time, influenced by advances in medicine and nutrition.
This developmental stage is becoming longer and includes more individuals.

Conceptions of Adolescence

Biological perspective: Puberty is often viewed as a period of hormonal fluctuations and stress.
Social perspective: Social and cultural influences play a crucial role in adolescent adjustment. There's a wide array of experiences.
Balanced perspective: Adolescent development involves biological, psychological, and social factors. Cultural differences influence the length and demands of the adolescent period.

Hormonal Changes in Puberty

The pituitary gland triggers the release of various hormones.
Growth hormone (GH) is released from the pituitary gland. Thyroxine (T4) is released from the thyroid gland, impacting metabolism and growth spurts.
Androgens: A group of hormones largely produced by the adrenal glands and testes (e.g., testosterone), but also found in adolescents with ovaries.
Estrogens: Primarily produced by the ovaries (e.g., estradiol) but also present in adolescents with testes.
Hormones are not the sole factor; chromosomes also play a role in adolescent differences.

Motor Development and Physical Activity

Gross motor skills typically improve during puberty.
Physical activity levels, including participation in physical education, often decrease with age.
There is a noticeable difference in physical education requirements from elementary school, middle school, and high school. Even more variations can be found between daily requirements of adolescents in different settings (e.g., school vs. work).

Brain Development in Adolescence

Pruning of unused synapses continues.
Myelination speeds up, strengthening connections between brain regions.
The prefrontal cortex continues to develop into the mid-20s.
Neurons become more receptive to excitatory neurotransmitters like dopamine.
Emotional/social network development outpaces cognitive control systems.
The limbic system (including hippocampus, amygdala, and hypothalamus) handles emotion, motivation, and memory. It interacts with other brain regions using dopamine.
The prefrontal cortex does not fully mature until the mid-20s.

Improvements in Memory in Adolescence

Memory processes include encoding (converting sensory information into short-term memory), consolidation (short-term to long-term memory), and retrieval (accessing stored information).
Adolescents can process information faster and more efficiently than younger individuals.
Sleep quality may affect memory function.

Sleep Habits in Adolescence

Adolescents need around 8-10 hours of sleep, similar to middle childhood.
Biological changes, evening social activities, and screen time contribute to later bedtimes.
Sleep deprivation negatively impacts cognitive tasks, potentially leading to anxiety symptoms, low mood, and high-risk behaviors.

Piaget's Cognitive Theory: Formal Operational Stage

Around age 11, individuals develop the capacity for abstract, systematic, and scientific reasoning (formal operations).
Hypothetico-deductive reasoning: involves starting with a hypothesis, deriving testable inferences, and systematically testing them.
Propositional thought: evaluating the logic of statements without necessarily referring to real-world situations.
Piaget noted the importance of language in formal operations.

Do All Individuals Reach the Formal Operational Stage?

Extensive guidance and practice are needed to develop abstract and systematic thought processes.
Lack of opportunity to solve hypothetical problems may lead to a failure to attain this developmental stage.

Adolescent Egocentrism

Piaget observed adolescents entering a world of hypothetical possibilities and showcasing a heightened focus on themselves.
Adolescent egocentrism stems from the belief of having unique and special thoughts.
This can manifest as an "imaginary audience" (belief that others are as interested in them as they are themselves) and a "personal fable" (belief that they are unique and invulnerable).
