logic
(noun)
Step-by-step thinking about how a problem can be solved or a conclusion can be reached.
Examples of logic in the following topics:
-
Defining Thoughts
- At this stage, kids learn through pretend play but still struggle with logic and taking the point of view of other people.
- Kids at this point of development begin to think more logically, but their thinking can also be very rigid.
- The final stage involves an increase in logic, the ability to use deductive reasoning, and an understanding of abstract ideas.
- Internal representations are gradually organized into logical structures, which first operate on the concrete properties of the environment, in the stage of concrete operations.
- Then, in the stage of formal operations, these logical structures operate on abstract principles that organize concrete properties.
-
Reasoning
- Reason is the capacity for consciously making sense of things, applying logic, establishing and verifying facts, and changing or justifying practices, institutions, or beliefs based on new or existing information.
- Deduction is the process of reasoning from one or more general statements, known as premises, to reach a logically certain conclusion.
- If all premises are true, the terms are clear, and the rules of deductive logic are followed, then the conclusion reached is necessarily true.
- Abduction is a form of logical inference that goes from an observation to a hypothesis that accounts for the observation.
- Two of the major forms of reasoning which utilize general statements, or premises, as well as specific statements in arriving at a logical conclusion.

Piaget's Stages of Cognitive Development
- Logical thinking is still not present, so children cannot rationalize or understand more complex ideas.
- It is characterized by the idea that children's reasoning becomes focused and logical.
- Children who do not yet grasp conservation and logical thinking will believe that the taller or larger glass must contain more liquid.
- By the end of this stage, children have developed logical and systematic thinking, are capable of deductive reasoning, and can create hypothetical ideas to explain various concepts.
- In postformal thinking, decisions are made based on situations and circumstances, and logic is integrated with emotion as adults develop principles that depend on contexts.
-
Cognitive Development in Adulthood
- In postformal thinking, decisions are made based on situations and circumstances, and logic is integrated with emotion as adults develop principles that depend on contexts.
- The need for specialization results in pragmatic thinking—using logic to solve real-world problems while accepting contradiction, imperfection, and other issues.

Psychology and the Scientific Method: From Theory to Conclusion
- The scientific method was first outlined by Sir Francis Bacon (1561–1626) and allows for logical, rational problem solving across many scientific fields.
- A hypothesis is a testable prediction that is arrived at logically from a theory.
- For a hypothesis to be falsifiable, it must be logically possible to make an observation or do a physical experiment that would show that there is no support for the hypothesis.
- It provides well-defined steps to standardize how scientific knowledge is gathered through a logical, rational problem-solving method.
-
Psychology and the Scientific Method
- A hypothesis is a testable prediction that is arrived at logically from a theory.
- Without critical thinking, logical conclusions cannot be drawn.
- In other words, a logical argument needs a specific reason and a valid conclusion in order to be considered scientific.
-
Reasoning and Inference
- Reason is the capacity for consciously making sense of things, applying logic, establishing and verifying facts, and changing or justifying practices, institutions, and beliefs based on new or existing information.
- A syllogism is a form of deductive reasoning in which two statements reach a logical conclusion.

Theories of Multiple Intelligence
-
Defining Intelligence
- Fluid intelligence (Gf) is the capacity to think logically and solve problems in novel situations, independent of acquired knowledge.
- In 1983, Howard Gardner published a book on multiple intelligence that breaks intelligence down into at least eight different modalities: logical, linguistic, spatial, musical, kinesthetic, naturalist, interpersonal, and intrapersonal intelligences.
-
Cognitive Psychology
- He is most widely known for his stage theory of cognitive development, which outlines how children become able to think logically and scientifically over time.
