چکیده

This paper describes a cognitively plausible computational theory of identifying perceptually indistinguishable objects (PIOs) based on a set of experiments which were designed to identify the knowledge and perceptual cues that people use for this purpose. Identifying a PIO in this context means connecting sensor data from some physical object either to a new mental level symbol or to the correct preexisting one, and is part of the solution to the symbol anchoring problem. We discuss several base cases in the identification process, some related intermediate cases and the knowledge that is needed for the general case. An algorithm for identifying PIOs is included.

Identifying Perceptually Indistinguishable Objects: Is That the Same One You Saw Before?

We are investigating a simulated cognitive robot that, when it sees an object perceptually indistinguishable from one it has seen before, will use reasoning to decide if they are two different objects or the same object perceived twice. We are currently conducting experiments with human subjects to determine what strategies they use to perform this task and how well they perform it. Identifying...

A Cognitive Robotics Approach to Identifying Perceptually Indistinguishable Objects

This paper describes a cognitively motivated computational theory of identifying perceptually indistinguishable objects (PIOs) based on a set of experiments, conducted with human participants, which were designed to identify the knowledge and perceptual cues that people use for this purpose. Identifying a PIO in this context means connecting sensor data from some physical object either to a new...

Identifying an Object that is Perceptually Indistinguishable from One Previously Perceived

People often encounter objects that are perceptually indistinguishable from objects that they have seen before. When this happens, how do they decide whether the object they are looking at is something never before seen, or if it is the same one they encountered before? To identify these objects people surely use background knowledge and contextual cues. We propose a computational theory of ide...

Tracking Perceptually Indistinguishable Objects Using Spatial Reasoning

Intelligent agents perceive the world mainly through images captured at different time points. Being able to track objects from one image to another is fundamental for understanding the changes of the world. Tracking becomes challenging when there are multiple perceptually indistinguishable objects (PIOs), i.e., objects that have the same appearance and cannot be visually distinguished. Then it...

The Neural Correlates of Crowding-Induced Changes in Appearance

Object recognition in the peripheral visual field is limited by crowding: the disruptive influence of nearby clutter. Despite its severity, little is known about the cortical locus of crowding. Here, we examined the neural correlates of crowding by combining event-related fMRI adaptation with a change-detection paradigm. Crowding can change the appearance of objects, such that items become perc...
