In Treisman's model of attention, a high threshold for a stimulus implies that:

• A. the stimulus will always be processed automatically regardless of its strength
• B. the stimulus is always ignored by the attentional system
• C. the stimulus is more likely to be noticed even if it is weak
• D. the stimulus is less likely to be consciously perceived unless it is particularly strong or relevant

Answer: (D)

Verified step by step guidance

1. Understand that Treisman's attenuation model of attention suggests that stimuli are processed with varying thresholds, meaning some stimuli need to be stronger to be noticed consciously.
2. Recognize that a 'high threshold' means the stimulus must reach a higher level of intensity or importance before it is consciously perceived.
3. Contrast this with a 'low threshold,' where even weak stimuli can be noticed because they require less intensity to be processed consciously.
4. Apply this understanding to the problem: a stimulus with a high threshold is less likely to be consciously perceived unless it is strong or relevant enough to surpass that threshold.
5. Conclude that the correct interpretation is that a high threshold means the stimulus is less likely to be consciously noticed unless it is particularly strong or relevant.
