Which of the following is a construct under "Word Recognition"?

Phonological awareness is indeed a key construct under "Word Recognition." This skill involves the ability to hear, identify, and manipulate the individual sounds in spoken words, which is fundamental for reading development. When a person is proficient in phonological awareness, they can recognize rhymes, segment words into their constituent sounds, and blend sounds together to form words. This skill directly impacts the ability to decode words while reading, as it helps individuals connect sounds with letters, making the reading process smoother and more efficient.

In contrast, vocabulary refers to the body of words a person knows and understands, which is more related to comprehension than to the mechanics of word recognition itself. Language structures encompass grammar and syntax, which also facilitate understanding but do not directly relate to recognizing words. Background knowledge involves the information and experiences a reader brings to a text, aiding in comprehension but not specifically in recognizing individual words. Thus, phonological awareness stands out as the most relevant construct for word recognition.
