In the following paper, I will examine the field of the word-forming process derivation and in that regard, I want to focus on prefixed words and their representation in the mental lexicon. Specifying that within my paper, I will scrutinize the question “Derivation and The Mental Lexicon – How are Prefixed Words Stored and Retrieved?”. The researched topic is relevant for the field of linguistics because it is not yet clarified how exactly words are stored and retrieved in the brain.
To get a closer insight on the topic of derivation and particularly the process of affixation and its connection to the mental lexicon I will conduct the help of several textbooks to give an overview of the process itself and the mental lexicon. Apart from that, I will use selected literature to zoom in on the specific field of word storage and examine a study that is concerned with this.
Since the study is based on lexical decision tasks, I am going to analyze the implemented experiments and interpret how prefixed words are stored, namely via morphological decomposition. Further, I will state why and how the experiments suggest that kind of processing and briefly examine other possible theories of word storage of prefixed words.

Objectives and Research Themes
The paper examines how prefixed words are processed, stored, and retrieved within the human brain, specifically investigating whether morphological decomposition is the primary mechanism for recognizing complex word structures.
- Theoretical definitions of the mental lexicon and morphemes.
- Psycholinguistic theories regarding word storage (whole-word vs. decomposition route).
- Analysis of lexical decision tasks to measure processing speeds.
- Investigation of affixation and its impact on word recognition.
- Critical evaluation of Taft and Forster’s (1975) experimental findings.
Excerpt from the Book
2. Theoretical Background
First, one might have the question on what the mental lexicon is. That question is not as easy to answer, since finding a brief and straight-forward definition for what the mental lexicon is can be challenging. It is not possible to physically examine the brain and find the mental lexicon as a part of it, rather one could describe the mental lexicon as an abstract theory to understand the way in that words are stored and later retrieved to form sentences. Following that, Lieber (2016, 15) suggests that the mental lexicon is “[…] the sum total of everything an individual speaker knows about the words of her language.” (Lieber 2016, 15), that includes knowledge about pronunciation, category, meaning, and syntactic properties.
When we now take a closer look on what is stored in the mental lexicon, the answer seems to be easier, in that we could just say words are stored in it. But from that arises the question “What exactly are words?”.
O’Grady et al. define words as “the smallest free form found in language” (O`Grady et al. 2011, 117), where a free form simply refers to the characteristic of free occurrence of the word. If we consider the following example from O’Grady et al. it becomes clearer: (1) Dinosaurs are extinct. Looking at it from a linguistic point of view, we can agree that dinosaurs is a word, but the plural marker -s is not, because as defined above, it is not a free form, i.e., does not appear without a reference word (O’Grady et al. 2011, 117). The plural marker cannot occur without the noun here, but in contrast the word dinosaur(s) can occur on its own and in different positions within the sentence and therefore is a word.
Chapter Summaries

2. Theoretical Background: Defines fundamental linguistic concepts such as the mental lexicon, words, morphemes, and the process of affixation.
3. Previous Research: Reviews existing theories on word storage, contrasting the whole-word route with the morphological decomposition route.
4. Research Question and Hypothesis: States the primary research question regarding the mental storage of prefixed words and proposes that morphological decomposition is the likely process.
5. Study: Details the experimental design of Taft and Forster (1975), explaining the use of lexical decision tasks with real stems and pseudo stems.
6. Results: Presents the findings from the three experiments, showing reaction times and error rates regarding the classification of prefixed words.
7. Discussion: Interprets the experimental data, concluding that morphological decomposition is the most probable mechanism for processing prefixed words.
8. References: Lists the academic sources used to support the analysis and theoretical framework.

Frequently Asked Questions
What is the core subject of this paper?
The paper focuses on the morphological process of derivation and how prefixed words are represented, stored, and accessed in the human mental lexicon.
What are the primary thematic areas?
The main themes include morphological theory, psycholinguistic models of word processing, and empirical evidence derived from lexical decision experiments.
What is the central research question?
The study asks: "How are prefixed words stored and retrieved?" and investigates whether they are processed via the whole-word route or morphological decomposition.
Which scientific methods are employed?
The author uses a literature-based theoretical analysis combined with an examination of empirical psychological experiments (lexical decision tasks) conducted by Taft and Forster.
What is covered in the main body of the work?
The main body defines core terms, reviews historical theories, details the methodology and results of Taft and Forster’s experiments, and discusses the implications of these findings.
Which keywords characterize the work?
Key terms include mental lexicon, morphological decomposition, derivation, prefixed words, and lexical decision tasks.
How does the "decomposition route" differ from the "whole-word route"?
The decomposition route assumes the brain breaks words down into smaller morphemes (e.g., prefix + root), whereas the whole-word route suggests words are stored as complete, indivisible units.
Why are lexical decision tasks important for this research?
They provide measurable data, specifically reaction times, which allow researchers to infer the complexity of the mental processing involved in identifying words versus non-words.
What was the significance of the "real stem" versus "pseudo stem" distinction?
This distinction allowed researchers to test if the brain automatically strips off prefixes to check for real word stems, which would indicate a systematic preference for morphological decomposition.
