Polarity correspondence in comparative number magnitude judgments

Distributed and overlapping cerebral representations of number, size, and luminance during comparative judgments Running title : Comparative judgments

How are comparative judgments performed in the human brain? We scanned subjects with fMRI while they compared stimuli for size, luminance or number. Regions involved in comparative judgments were identified using three criteria: task-related activation; presence of a distance effect; and interference of one dimension onto the other. We observed considerable overlap in the neural substrates of t...

Magnitude comparison extended: how lack of knowledge informs comparative judgments under uncertainty.

How do people compare quantitative attributes of real-world objects? (e.g., Which country has the higher per capita GDP, Mauritania or Nepal?). The research literature on this question is divided: Although researchers in the 1970s and 1980s assumed that a 2-stage magnitude comparison process underlies these types of judgments (Banks, 1977), more recent approaches emphasize the role of probabili...

Can conceptual congruency effects between number, time, and space be accounted for by polarity correspondence?

Conceptual congruency effects have been interpreted as evidence for the idea that the representations of abstract conceptual dimensions (e.g., power, affective valence, time, number, importance) rest on more concrete dimensions (e.g., space, brightness, weight). However, an alternative theoretical explanation based on the notion of polarity correspondence has recently received empirical support...

Comparative cognition: Human numerousness judgments

Previous studies regarding numerousness judgments of dot displays showed humans to be accurate to 6 dots and 2 monkeys to be accurate to 8 dots and l monkey to 9 dots. However, the monkeys performed numerousness discrimination involving pairs of dot arrays and the humans made absolute numerousness judgments involving as many as 35 dot arrays. With 140 humans we replicated as closely as possible...
