Phasic heart rate changes during word translation of different difficulties

Area of Science:

• Cognitive psychology
• Psychophysiology
• Neuroscience

Background:

• Heart rate (HR) changes are linked to mental activities, including cognitive processing.
• Understanding how specific cognitive tasks influence physiological responses like HR is crucial for cognitive science.

Purpose of the Study:

• To investigate heart rate (HR) changes during word translation.
• To determine the influence of translation task difficulty on HR modulation.

Main Methods:

• Twelve translation and interpreting students performed English-to-German word translation.
• Stimuli included high/low-frequency words and familiar/unfamiliar technical terms.
• Event-related HR changes were analyzed in relation to task difficulty.

Main Results:

• Increased translation difficulty correlated with more significant HR deceleration.
• Anticipatory HR deceleration and HR changes from motor preparation/typing were not difficulty-dependent.

Conclusions:

• Task difficulty in language translation is associated with specific event-related HR changes.
• This provides initial evidence for a psychophysiological link between cognitive load in translation and HR modulation.
