Deductive reasoning is studied in logic, psychology, and the cognitive sciences. [3] [1] Some theorists emphasize in their definition the difference between these fields. On this view, psychology studies deductive reasoning as an empirical mental process, i.e. what happens when humans engage in reasoning.
For example, the argument, "All young girls wear skirts; Julie is a young girl; therefore, Julie wears skirts" is valid logically, but is not sound because the first premise isn't true. The syllogism is a form of deductive reasoning in which two statements reach a logical conclusion. With this reasoning, one statement could be "Every A is B ...
[1] [2] [3] It is one of the most famous tasks in the study of deductive reasoning. [4] An example of the puzzle is: You are shown a set of four cards placed on a table, each of which has a number on one side and a color on the other. The visible faces of the cards show 3, 8, blue and red.
A syllogism (Ancient Greek: συλλογισμός, syllogismos, 'conclusion, inference') is a kind of logical argument that applies deductive reasoning to arrive at a conclusion based on two propositions that are asserted or assumed to be true.
Non-deductive reasoning is an important form of logical reasoning besides deductive reasoning. It happens in the form of inferences drawn from premises to reach and support a conclusion, just like its deductive counterpart. The hallmark of non-deductive reasoning is that this support is fallible.
Abductive reasoning is a form of inference which goes from an observation to a theory which accounts for the observation, ideally seeking to find the simplest and most likely explanation. In abductive reasoning, unlike in deductive reasoning, the premises do not guarantee the conclusion.
Deductive reasoning – Form of reasoning – from meaning postulate, axiom, or contingent assertion: if p then q (i.e., q or not-p) Inductive reasoning – Method of logical reasoning – theory formation; from data, coherence, simplicity, and confirmation: (inducibly) "if p then q"; hence, if p then (deducibly-but-revisably) q
For example, he believed that children experience the world through actions, representing things with words, thinking logically, and using reasoning. To Piaget, cognitive development was a progressive reorganisation of mental processes resulting from biological maturation and environmental experience.
