Testing the multiple in the multiple read-out model of visual word recognition.

Area of Science:

• Cognitive Psychology
• Psycholinguistics
• Human Information Processing

Background:

• The multiple criteria concept explains lexical decision-making.
• The multiple read-out model (Grainger & Jacobs, 1996) posits that response criteria influence word recognition.
• Previous research has not fully explored how accuracy vs. speed demands modulate these criteria.

Purpose of the Study:

• To empirically test the predictions of the multiple criteria concept in lexical decision tasks.
• To investigate how manipulating accuracy and speed emphases affects masked neighbor effects.
• To validate the role of adjustable response criteria in word recognition.

Main Methods:

• Lexical decision tasks were employed to assess word recognition.
• Two experiments manipulated task demands: Experiment 1 stressed accuracy, while Experiment 2 stressed response speed.
• Masked neighbor priming was used to measure the influence of prime words on target word identification.
• Performance was compared against control conditions without specific accuracy or speed emphasis.

Main Results:

• Experiment 1 (accuracy stress) revealed a significantly stronger neighbor-inhibition effect compared to the control condition.
• Experiment 2 (speed stress) demonstrated facilitation from the neighbor prime, contrasting with the control condition.
• The findings indicate that response criteria dynamically adjust based on task demands.

Conclusions:

• The results provide strong support for the multiple criteria concept in lexical decision.
• Adjustable response criteria, influenced by accuracy and speed demands, play a crucial role in word recognition.
• The multiple read-out model effectively accounts for the observed modulations in masked neighbor effects.
