Comprehension of prenominal adjective orders

Area of Science:

• Cognitive Psychology
• Linguistics
• Psycholinguistics

Background:

• Adjective order influences language processing and comprehension.
• The relationship between adjective order, referent properties, and contextual information is not fully understood.

Purpose of the Study:

• To investigate how the order of prenominal adjectives affects the identification of a referent object.
• To examine the influence of non-referent context (differing in size, number, or color) on adjective order effects.

Main Methods:

• Two experiments were conducted using phrases with two prenominal adjectives.
• Participants identified the position of a referent object in a display.
• The order of adjectives (normal vs. inverted) and the nature of the non-referent context were manipulated.

Main Results:

• Adjective order significantly affected referent identification times.
• Normal adjective order facilitated identification when the non-referent differed in size or number.
• Inverted adjective order led to faster identification when the non-referent differed in color.

Conclusions:

• These findings support a pragmatic communication principle.
• Ordering more discriminating adjectives earlier in a series enhances comprehension and processing efficiency.
• Contextual factors, specifically the properties of non-referent distractors, modulate the optimal adjective order.
