Picture Analogy Error Pattern in a Five-Year-Old
Ms. Rivera, a kindergarten teacher, reviews a screening packet for a 5-year-old, Mateo. The verbal battery includes 10 picture-analogy items and 8 picture-classification items. Mateo answers 7 of 10 analogies correctly. His correct items involve familiar animal young (cow-calf), object function (spoon-eat), and opposites (hot-cold). His three errors involve part-whole relations (tree-branch, house-roof) and location (bird-nest). On classification, he sorts 5 of 8 groups correctly; his errors occur when color and function conflict, such as a red toy car among red fruits. He names all pictures accurately and speaks English at home. The team must decide whether his profile reflects a vocabulary gap or a relational-reasoning gap, and whether to repeat the verbal battery after targeted instruction. Testing time was 18 minutes, within limits.
1. What pattern in Mateo's errors is most diagnostically useful, and what alternative explanation must be ruled out?

The most diagnostic pattern is the type of relation, not the number correct. Mateo succeeds when the relation is a familiar noun pair or a strong functional opposite and fails on part-whole and location relations. That pattern is more consistent with relational reasoning than with a broad vocabulary gap because he names all pictures and solves several analogy types. However, before concluding, rule out item-specific vocabulary: he may know 'branch' but not the whole-part schema, or he may not have heard 'nest' in a location context. The classification errors when color and function conflict support a reasoning interpretation: he can group by a salient perceptual feature but does not consistently shift to function. A vocabulary-only explanation would predict errors across all analogy types, including animal young, which he did not show.
2. Describe one follow-up item you would administer and how you would score it.

Administer two parallel part-whole analogies with familiar objects: 'hand is to arm as foot is to ___' with picture choices leg, shoe, toe. Then a location analogy: 'bird is to nest as bee is to ___' with hive, flower, honey. Score separately for choosing the correct relation and for naming the target picture. If he chooses 'leg' and 'hive' but cannot explain, the issue is relational selection, not vocabulary. If he misnames 'hive' and chooses 'flower', vocabulary is implicated. Also ask him to explain one correct item; a verbal explanation is not required for CogAT but helps distinguish guessing from rule use.
3. What instructional recommendation follows from the profile?
Read the worked answer
Recommend small-group practice with explicit relational categories: part-whole, location, function, and category, using manipulative sorts and verbal labels. Do not repeat the full verbal battery immediately; first provide 3-4 weeks of targeted instruction, then re-administer only the analogy and classification subtests. Because his classification errors are tied to color salience, include sorting tasks where color is irrelevant. Keep the recommendation tied to reasoning, not just score: if he improves after instruction, the original score likely underestimated his reasoning; if not, further language screening is warranted. Avoid retention or special education referral based on one verbal screening.
