Semantic interference in picture naming during dual-task performance does not vary with reading ability

Area of Science:

• Cognitive Psychology
• Psycholinguistics

Background:

• Dual-task studies on semantic interference in picture naming yield inconsistent results.
• Previous research suggests reading skill might explain variations in semantic interference effects.

Purpose of the Study:

• To investigate the influence of reading ability on semantic interference during picture naming in a dual-task paradigm.
• To test the hypothesis that better reading skills reduce semantic interference at short stimulus onset asynchronies (SOAs).

Main Methods:

• Participants performed a dual-task involving tone discrimination and picture naming with distractor words.
• Varying stimulus onset asynchronies (SOAs) were used between the tone and distractor word.
• Participants' reading ability was measured and correlated with the semantic interference effect.

Main Results:

• The semantic interference effect magnitude was consistent across both short and long SOAs.
• Participant reading ability predicted naming speed but not the magnitude of the semantic interference effect.
• Findings contradict the reading-ability account for semantic interference.

Conclusions:

• The magnitude of semantic interference in picture naming during dual-task performance is independent of reading skill.
• Reading ability does not modulate the locus or extent of semantic interference in this context.
