In word processing studies, visual word recognition is affected by several factors, including the following:
1. Proficiency: The ability of an individual to process words efficiently depends on their language proficiency, especially their familiarity with the written forms of words.
2. Word length: Longer words are often harder to recognize visually, as they require more cognitive processing compared to shorter words.
3. Neighborhood effect: This refers to the phenomenon where words that are visually or phonetically similar to other words in the lexicon (i.e., their "neighborhood") can affect recognition. For example, "hat" and "bat" are in the same neighborhood, and this can influence the speed and accuracy of word recognition.
Thus, the correct answer is (A) Proficiency, word length, neighborhood effect.
