Capacity Limits on Visual Imagination

Discrete capacity limits in visual working memory.

The amount of information we can actively maintain 'in mind' is very limited. This capacity limitation, known as working memory (WM) capacity, has been of great interest because of its wide scope influence on the variety of intellectual abilities. Recently, there has been an ongoing debate about how this capacity should be best characterized. One viewpoint argues that WM capacity is allocated i...

Visual Imagination from Texts

Imagination is a fundamental ability of humans which resides in the cognitive system. We propose a connectionist model that generates images from a given sentence after trained on a dataset of image-sentence pairs. The model is composed of language model and image model that are connected with a latent variable constrained by a prior distribution. The latent variable encodes dual information an...

Zeolite nanosystems: Imagination has no limits.

On the limits of dynamic imagination: A mental extrapolation task

To mentally extrapolate the trajectory of a moving object which disappears from sight, it is possible to exploit two different sources of information. One source is the memory of the last visible movement of the object, and the other is its inferred movement through time. It is often assumed that these cues are integrated into dynamical analog mental representations. To investigate the nature o...

Perceptual capacity limits in visual detection and search

The present research tests limitedand unlimited-capacity theories of perception by comparing accuracy in detection and search tasks under conditions of simultaneous and successive presentation of array items. The unlimited-capacity approach predicts no difference between simultaneous and successive presentation when nonperceptual factors are controlled. The limitedcapacity approach predicts an ...
