Accentuate the positive: semantic access in english compounds

Area of Science:

• Psycholinguistics
• Cognitive Psychology
• Computational Linguistics

Background:

• Investigating semantic effects in word processing is crucial for understanding language comprehension.
• Previous research has explored how word meaning influences recognition, but the role of morpheme semantics in complex words requires further clarification.

Purpose of the Study:

• To examine the influence of morpheme semantics on the recognition of English compound words.
• To evaluate the contribution of semantic properties like emotional and sensory connotations to word recognition.

Main Methods:

• Behavioral experiments measuring recognition latencies for compound words and their constituent morphemes.
• Analysis of six semantic properties (emotional, sensory, semantic richness) of compounds and morphemes.

Main Results:

• Compound semantics affected compound recognition latencies; morpheme semantics affected isolated morpheme recognition.
• Morpheme semantics had minimal impact on compound recognition, except for negative morphemes increasing recognition time (e.g., 'seasick').

Conclusions:

• Data challenges obligatory decomposition and dual-route models of morphological processing.
• Supports the naive discriminative learning account, suggesting simultaneous, unmediated access to meanings activated by visual input.
• Selectivity and attention division are key factors in complex word recognition.
