What people are saying
Discussions reflect a general interest in the research's connection to broader vision science topics, such as motion perception and perceptual calibration, with examples like references to symmetry with earlier work and mention of related experiments. The tone suggests respect for the work’s significance but stops short of strong enthusiasm or critique, emphasizing its role in ongoing scientific dialogues.
Most discussions acknowledge the relevance of the article, with some referencing related concepts in vision science, indicating general agreement on its significance.
The posts show mild interest, with some sharing background knowledge and linking to other foundational studies, suggesting a curiosity without deep critique or enthusiasm.
Participants reference specific studies and methodological approaches, demonstrating moderate engagement, but tend to stay at a surface level without deep critique or exploration.
The discussions imply that the article contributes to ongoing conversations but don't highlight immediate transformative effects, leading to a neutral impact assessment.
Abstract in brief
- The study reveals that mathematical singularities in Signal Detection Theory can lead to unreliable parameter estimation in contrast discrimination tasks using the 2-Alternative-Forced-Choice (2AFC) method.
- To address this issue, the researchers introduced an Identification Task (IT), which allows observers to identify one out of multiple contrasts, resulting in more consistent data across experimental sessions.
- Results showed that Contrast Response Functions exhibited high gain at low contrasts and low gain at high contrasts, while Noise Amplitudes decreased at low contrasts and stabilized at higher contrasts, aligning with the behavioral dip in Threshold versus Contrast curves.

Neither great for old papers though. So, clicking through the @scite link (takes me here: https://t.co/R6303uRKis) shows me snippets of text from the papers which cite this paper.

@tsawallis @ConstantinRoth1 @RucciMichele @HafedLab In a seminar on vision, shouldn’t papers that do not consider eye movements be the exception? But I suppose 1 paper per seminar does reflect the proportions in the classics in vision science accurately.
The one of special interest is the one marked as 'supporting' (https://t.co/3IXx2hmC24). It seems like @scite use a black box to make these distinctions, but it’s enough to make me actually skim the paper and see what they’re saying.

@PsychScientists Sure, there's a physical cause, but it need not be an actual visual target being tracked. See also https://t.co/PNophm7xKS
By removing the lens, we get less UV absorption! And some of this UV light is picked up by the S cone, resulting in a visible color signal in our brain https://t.co/Os11RrXTa9

@StevenDakin best I've found so far Hess, R. F., & Field, D. (1993). Is the increased spatial uncertainty in the normal periphery due to spatial undersampling or uncalibrated disarray? Vision Research, 33(18), 2663–2670. https://t.co/BFMlXcDpG8
Our sensitivity to speed changes and the way we smoothly pursue moving objects of different speeds are correlated. However, expectation and training affect the sensorimotor relationship between eye velocity and target velocity. https://t.co/LvIfOB3tqx

I am influenced by our earlier work on perceiving object shape. We found strong evidence that disparity is used hierarchically: as uncalibrated as possible given the task, but something like a Euclidean representation if necessary. https://t.co/Gqn1kjMmlm 3/3 https://t.co/nXvuWuNK64

@michaelshawbond @JohnKubie @hugospiers @TrendsCognSci @esolomon @PNASNews The same argument was played out in the 1990s in relation to perceived object shape. The spectrum there is from ordinal depth relations up to Euclidean shape. Again, at the most calibrated end, impossible to distinguish representations empirically. https://t.co/Gqn1kjMmlm 5/9
