This manuscript describes an approach to measure neural activity of humans while solving spatially focused engineering problems. The electroencephalogram methodology helps interpret beta brain wave measurements in terms of neural efficiency, with the aim of ultimately enabling comparisons of task performance both between problem types and between...

Automated 3D Optical Coherence Tomography to Elucidate Biofilm Morphogenesis Over Large Spatial Scales

7.3K
Microbial biofilms form complex architectures at interphases and develop into highly scale-dependent spatial patterns. Here, we introduce an experimental system (hard- and software) for the automated acquisition of 3D optical coherence tomography (OCT) datasets. This toolset allows the non-invasive and multi-scale characterization of biofilm morphogenesis in space and...

Conscious and Non-conscious Representations of Emotional Faces in Asperger's Syndrome

14.4K
An EEG experimental protocol is designed to clarify the interplay between conscious and non-conscious representations of emotional faces in patients with Asperger's syndrome. The technique suggests that patients with Asperger's syndrome have deficits in non-conscious representation of emotional faces, but have comparable performance in conscious representation with healthy...

Confirmation Biases01:31

Confirmation Biases

7.9K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Area of Science:

  • Cognitive Psychology
  • Spatial Navigation
  • Human Perception

Background:

  • Humans can maintain awareness of objects during navigation, even when out of sight.
  • The internal representation used for spatial awareness is a subject of ongoing scientific debate.

Purpose of the Study:

  • To investigate the accuracy and reliability of human spatial representation.
  • To determine if a stable 3D model is used for updating visual direction of unseen targets.

Main Methods:

  • Participants viewed targets from a specific location.
  • Participants then moved to a new location and pointed towards the remembered targets.
  • Experiments were conducted in both virtual reality and real-world environments.

Main Results:

  • Consistent and significant pointing errors were observed.
  • These errors are not well-explained by a stable 3D representation of the environment.
  • The data suggest that the orientation of occluding elements influences spatial memory recall.

Conclusions:

  • The mechanisms for updating visual direction of unseen targets do not rely on a stable 3D scene model.
  • Spatial awareness likely involves more dynamic or flexible representational strategies than a fixed 3D map.
