Priming is a well-known phenomenon in psycholinguistics, speech-language pathology, and cognitive psychology, frequently observed in people of all ages. When we are exposed to\u2014or think about\u2014a word or concept, our brain automatically activates items that share common features. Take, for example, a conversation between Pascale and Val\u00e9rie in the laboratory (Figure 1):<\/b><\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t

Do you recognize yourself in this kind of funny situation? In this context, a\u00a0<\/span>phonological priming effect<\/strong>\u00a0<\/span>occurred: since the first sounds of the words\u00a0<\/span>Albert<\/em>\u00a0<\/span>and\u00a0<\/span>Alexandre<\/em>\u00a0<\/span>are the same, Pascale\u2019s brain can sometimes activate the wrong word!<\/p><\/div>

Let\u2019s take another example. Read the sentence below carefully:
The firefighters barely managed to put out the _______.<\/strong>
Did you involuntarily think of the word \u201cfire\u201d after reading this sentence? That\u2019s another example of\u00a0<\/span>priming<\/strong>! Indeed, the word\u00a0<\/span>fire<\/em>\u00a0<\/span>is strongly associated with the words\u00a0<\/span>firefighter<\/em>\u00a0<\/span>and\u00a0<\/span>put out<\/em>. This is a\u00a0<\/span>semantic priming effect<\/strong>, based on a meaning association rather than a sound association.<\/p><\/div>

These phenomena reveal how our knowledge of words and concepts is organized in the brain. This information is arranged in vast, complex networks of interconnected items. When one item is activated in our brain, other items sharing common features are also activated, forming chains of activation of varying intensity (Figure 2).<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

Figure 2. Organization of Knowledge and Priming Effect. A. Thinking of a name that begins with the sounds \/al\/ primes other names that start with the same sounds. Words we are more frequently exposed to or that are more strongly connected produce a stronger priming effect. B. Exposure to the word \u201cfirefighter\u201d also primes other items that are related in meaning.<\/figcaption>\n\t\t\t\t\t\t\t\t\t\t<\/figure>\n\t\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

From the 20th century onwards, numerous scientific studies have demonstrated the existence of the priming effect, notably through\u00a0<\/span>word recognition tasks with priming<\/strong>. These tasks involve reading or listening to sequences of words or pseudowords [1], and indicating as quickly as possible whether a word is real or not (usually by pressing a button) (Figure 3). Some of the presented words are associated: in this context, the first word presented is called the\u00a0<\/span>prime<\/strong>, while the next word is called the\u00a0<\/span>target<\/strong>. Many of these studies show that words preceded by a prime are recognized more accurately and more quickly than words without a prime.<\/p><\/div>\t\t\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/div>\n\t\t\t\t\t<\/div>\n\t\t<\/section>\n\t\t\t\t

These results shed light on how our\u00a0mental lexicon<\/strong>\u2014that is, the set of words we know and store in memory\u2014is organized. Every time we speak, read, or hear words, we access our mental lexicon to recognize and understand them. Findings from priming studies suggest that the mental lexicon is not just a simple dictionary arranged in alphabetical order. Rather, it acts like an internal search engine: as soon as we think of or are exposed to a word\u2014or part of a word\u2014our brain automatically activates suggestions, much like Google suggests different options when we start typing a search query.<\/p>

These conclusions can be applied to different types of mental representations; indeed, many forms of\u00a0priming<\/strong>\u00a0have been discovered:<\/p>
