In a lexical decision task, participants are presented with strings of letters and must quickly determine whether each string is a real word or a non-word. The task requires the individual to rely on their knowledge of the language and their ability to quickly access this information to make a decision.

The best selection of stimuli for this task is critical. The chosen words should be familiar and easily recognizable, while the non-words should be constructed in a way that they do not resemble real words too closely.

In the given answer choice, the words "pizza" and "history" are both well-known and commonly used terms in everyday language. Their recognition is likely to be strong among a broad range of participants, thus facilitating a clear and effective lexical decision-making process. Additionally, the non-words "pibble" and "girk" have a phonetic structure that may appear plausible but are not actual words, making them effective counterpoints to challenge participants' lexical knowledge without being too obviously non-lexical.

Overall, using familiar and contextually relevant words alongside non-words that maintain a reasonable level of linguistic structure enhances the validity and efficacy of the task, allowing for a more accurate measurement of participants' lexical processing abilities.
