A logic test or assessment aims to measure your ability to apply logical reasoning methods when presented with problem-solving tasks. Those tasks can be verbal, numerical or pictorial. The Thomas General Intelligence Assessment (GIA) measures your ability to apply logical reasoning across five areas: Reasoning, Perceptual Speed, Number Speed & Accuracy, Word Meaning and Spatial Visualisation.
What is logic?
The word comes from the Greek word logos, which is varyingly translated or defined as 'reason' or 'thought'. Essentially, it is the study of reasoning or a set of general principles for distinguishing sound conclusions (or truths) from false ones.
The philosopher Aristotle said that logic enables us to learn what we don't know and that its conclusions are inescapable.
Logic is not concerned with psychological processes connected with thought, emotions or images. It deals with assertions (or declarations) as opposed to questions or sentences expressed as wishes, which are capable of being true or false.
Logic has three important things:
- Consistency – no one thing contradicts another thing
- Soundness – you can never get a false inference from a true premise
- Completeness – there are no true statements that cannot be proved by the process
Here's a simple example:
If Thomas is a leader, then Thomas is in charge. Thomas is a leader. Therefore, Thomas is in charge.
How to complete a logical reasoning test
Logical reasoning tests often assess ability using information provided in sequences. The test taker is required to identify underlying rules and patterns in the sequence in order to identify what should come next.
Successfully completing a logical reasoning test is hugely influenced by being good at active reading and thinking about what is being explained; establishing what the topic is; asking yourself questions about the passage, diagram or sequence and being able to paraphrase the more complicated elements.
Logical reasoning tests are usually timed and typically, the easier questions are at the beginning of the test. You also need to remember that there is only ever one correct answer. Logical reasoning tests can be used in recruitment to predict job performance. These tests can also be numerical (number based), verbal (word based), or diagrammatic (picture based).
