The book "Metacognitive Feelings of Knowing Judgments in Target Words Retrieval" by Majda Layek offers a comprehensive examination of metacognitive judgments, particularly the phenomenon of "Tip of the Tongue" (TOT). This study analyzes the validity of metacognitive judgments that occur when a person struggles to retrieve a word from memory but feels that the retrieval is imminent. The author conducts a survey to explore the relationships between felt knowledge judgments and the actual retrieval of target words. The aim is to question the hypotheses that suggest metacognitive judgments in the TOT state are reliable indicators of successful word retrieval. This academic book is aimed at readers interested in the psychology of memory and the mechanisms of word retrieval.
