What kind of task it is
In an "A : B = C : ?" format, this task asks you to read the relationship between two words and apply the same relationship to another word.
For example, if the item is "hammer : nail = screwdriver : ?", the answer is "screw." The relationship is "tool used on something → thing it is used on," and that relationship needs to be applied to another pair.
The relationship patterns vary. They may include cause and effect (fire : smoke), tool and object (scalpel : tissue), part and whole (key : piano), contrast (day : night), and other patterns that cannot be solved by simple association alone.
Knowing the meanings of the words is not enough. The task asks for the ability to detect the "relationship pattern" between words and apply it to another situation.
What it measures
Within the five domains of BrainTypeIQ, this is one task that measures Gc (crystallized intelligence). However, it uses not only knowledge of word meanings, but also the ability to find relationships between words.
- Understanding word meanings and usage → Gc (vocabulary and knowledge)
- Finding the relationship pattern and transferring it to another pair → Gf (fluid reasoning)
The other Gc task, Vocabulary (Antonyms), handles word meanings more directly. The Analogies task handles relationship reasoning through words. It is classified under Gc, but it also includes processing close to Gf.
For Gc overall, see what crystallized intelligence (Gc) is.
When the score is higher
When the Analogies score is higher, shared relationship structures are easier to find using word meanings as cues.
For example, a principle learned in one field may be easier to apply to another field. When explaining a complex concept, it may be easier to find a corresponding relationship to something the other person already knows. When seeing a new problem, similarities with a previously handled problem may stand out.
This ability appears not only in memorizing knowledge as it is, but in using knowledge by connecting it with other knowledge.
When the score is lower
Even when the Analogies score is lower, it cannot by itself judge intellectual ability as a whole. Several factors overlap in the score.
- Vocabulary assumptions do not fit - Even if the reasoning direction is appropriate, unfamiliar word meanings or usage can make the relationship harder to find
- Surface similarity is easier to prioritize - Attention may go to options that feel close in impression, while the relationship pattern is missed
- Several words must be handled at once - A, B, C, and the options need to be held and compared, so working memory is also used
In particular, it is hard to separate vocabulary knowledge from reasoning ability using Analogies alone. Nonverbal reasoning is more likely to appear in Matrix Reasoning and Figure Weights, while word knowledge also appears in Vocabulary (Antonyms).
BrainTypeIQ is a 9-task online IQ test that includes Analogies and shows overall IQ and the five-domain cognitive profile. Reading several tasks together, rather than one task alone, makes the meaning of the result easier to see.
