Lecture 10b: Cognitive Development in Adolescence Flashcards
What is abstract thinking?
Logic and reasoning in which the adolescent mentally manipulates ideas and reflects on situations that are
not real or tangible
What is Propositional thought?
The ability to determine whether a set
of propositions (statements) are logical based on the wording of the statement
What is Hypothetical-deductive Reasoning?
A systematic, scientific approach to problem solving in which they test hypotheses about variables that might influence an outcome to arrive at (deduce) a conclusion
What are examples of Piagetian tasks?
– Combinations of liquids problem
– Pendulum problem
What is the Combinations of liquids problem?
The combination of liquids problem entails determining which liquid or combination of liquids causes a chemical reaction that produces a vibrant yellow liquid.
In this task, Piaget presented children and adolescents with four large bottles filled with liquid (labeled 1–4) and test beakers that contained clear-colored liquid (FIGURE 15.2). Piaget then demonstrated that a drop of liquid “g” produces a bright yellow liquid in the beaker. But where does the mysterious liquid “g” come from?
The goal is to figure out which liquids from the four bottles, either alone or in combination, combine with liquid “g” to produce a color change.
What is the Pendulum Problem?
In the pendulum problem, Piaget gave children and adolescents a set of weights varying in heaviness and strings of different lengths
The challenge was to figure out which variable(s) affect the rate of the pendulum’s swing: the length of the string, heaviness of the weight, height of the release, or force of the push.
What is Selective attention?
The ability to focus on relevant information while inhibiting attention to irrelevant
What is Attention flexibility?
Ability to flexibly shift attention from one
task or problem to the other as needed
What is the flanker task?
Flanker tasks require focusing on a relevant stimulus while inhibiting attention to distractors. An adolescent might be instructed to signal the direction an arrow is facing by pressing on a right or left button.
The task becomes increasingly difficult when the arrow is surrounded (flanked) by many distractor arrows facing the opposite direction
What are Switching tasks?
Switching tasks assess the ability to shift attention to different target stimuli.
For example, the adolescent might be instructed to press buttons or touch computer screens in response to pictures and their locations.
They might be told that when a picture appears in the top half of a computer’s window, they should determine whether it is an animal, but when the picture appears in the bottom half they should determine whether it is a number.
This requires adolescents to simultaneously attend to the location and pictures, and quickly shift between different responses.
What is Working memory?
Working memory refers to the manipulation and temporary storing of information in active memory
What is the working memory?
Working memory span refers to how many items or chunks of information an individual can actively hold in mind
Working memory span increases from childhood through adolescence
What is Automatic processes?
Automatic processes are cognitive activities that require no effort and therefore do not drain the limited cognitive resources available in working memory
What is cognitive load?
When individuals expend a lot of mental effort or resources on a problem, researchers refer to as cognitive load because working memory becomes depleted and performance declines
What is processing speed?
How quickly and efficiently a person encodes information or solves a problem
