The principle of full decomposition explains how words are processed. This study shows that embedded pseudo-constituents in pseudo-compounds are suppressed, unlike true morphemes in compounds.
Area of Science:
- Psycholinguistics
- Cognitive Science
- Computational Linguistics
Background:
- The edge-aligned embedded word activation theory and principle of full decomposition posit that (pseudo)morphemes are extracted from word edges.
- Embedded words are activated when a whole word can be decomposed into constituent (pseudo)morphemes, facilitating access to other embedded morphemes.
Purpose of the Study:
- To replicate findings on English compound words regarding the principle of full decomposition.
- To investigate the principle of full decomposition in English pseudo-compounds.
Main Methods:
- Replication of Taikh et al. (2024) study using English compound words.
- Examination of processing in English pseudo-compounds by manipulating boundary and constituent-internal letters.
Main Results:
- Replacing boundary letters in compounds slowed processing, consistent with full decomposition.
- Replacing pseudo-boundary and pseudo-constituent letters in pseudo-compounds similarly slowed processing.
- Findings suggest embedded pseudo-constituents are suppressed and do not facilitate pseudo-compound access.
Conclusions:
- The principle of full decomposition is supported in English compounds.
- Embedded pseudo-constituents in pseudo-compounds are suppressed and do not facilitate word access.
- Facilitation may be inhibited if word recognition necessitates strong suppression of embedded words.

Conjugate Addition (1,4-Addition) vs Direct Addition (1,2-Addition)
Conjugate addition results in a thermodynamically stable product. The reaction retains the stronger C=O bond at the expense of the weaker C=C π bond. The process is slow as the β carbon is less electrophilic than the carbonyl carbon.
