Contrary to Expectations: Does Context Influence the Processing Cost Associated with Negation?

Area of Science:

• Psycholinguistics
• Cognitive Science
• Linguistics

Background:

• Negative sentences pose processing challenges, especially out of context.
• Plausible denial contexts can mitigate or eliminate this processing difficulty.
• Discourse markers are hypothesized to trigger denial contexts.

Purpose of the Study:

• To investigate if denial contexts, triggered by discourse markers, ease the processing of negation.
• To determine the conditions under which plausible denial reduces negation processing costs.
• To examine the interaction between context type (denial vs. non-denial) and sentence polarity (affirmative vs. negative).

Main Methods:

• Six behavioral experiments were conducted.
• Tasks included sensibility judgments and self-paced reading.
• Stimuli varied in sentence polarity, context type (minimal/extended denial, non-denial), and narrative length.

Main Results:

• Context and polarity significantly affected processing, but no interaction was found in initial experiments.
• Minimal denial contexts triggered by discourse markers alone did not facilitate negation processing.
• Extended denial contexts with explicit mentions and longer narratives eliminated processing difficulty.
• Facilitation was observed when discourse markers were used in longer narratives.

Conclusions:

• Discourse markers alone are insufficient to ease negation processing in denial contexts.
• Explicitly stating the denied expectation and providing longer narratives are crucial for facilitation.
• Pragmatic factors like relevance and informativity play a decisive role in easing the processing of negative sentences in denial contexts.
