We tend to notice faces everywhere, even in inanimate objects (a phenomenon known as pareidolia). This can be explained using an evolutionary perspective, as it would be more consequential to miss recognizing the face of a predator compared to mistakenly seeing a face in a leaf, for instance. What does this look like in a Signal Detection Theory framework? We do not need that much evidence of 'face-ness' to see a face, which can be thought of as shifting the decision criterion to the left. This increases false alarms, but reduces the miss rate. , Not Selected Incorrect answer: We need more evidence of 'face-ness' to see a face, which can be thought of as shifting the decision criterion to the left. This increases the miss rate, but reduces the false alarm rate. Correct Answer: We do not need that much evidence of 'face-ness' to see a face, which can be thought of as shifting the decision criterion to the left. This increases false alarms, but reduces the miss rate. We do not need that much evidence of 'face-ness' to see a face, which can be thought of as shifting the decision criterion to the right. This increases false alarms
