Effect of Experience on Collective Decision-Making and Social Organization
Tovah Kashetsky, Grant Doering, and Reuven Dukas
Expertise built from experience allows individuals to perform significantly better than novices on a complex task. Social groups can also demonstrate expertise. Within social groups, collective decision-making is crucial for maintaining cohesion, but it is unknown whether a group’s collective decision-making skills can improve with experience. To investigate this, we tested whether repeated experience with choosing between multiple nests during emigration in house-hunting ants (Temnothorax ambiguus) would improve the speed and efficiency with which colonies reach consensus. We hypothesize that experience with decision-making would improve colony performance on future decisions. We first ran preliminary experiments to quantify nest features that colonies prefer in order to construct artificial nests of varying attractiveness. We will provide 20 colonies experience with a choice between a good- and poor-quality nest during emigration, and 20 colonies with no choice during emigration (a single nest). Lastly, we will test all colonies to decide between a good- and poor-quality nest during a final emigration. So far, we found that colonies with experience decision-making do indeed appear to be faster and more efficient at decisions than colonies without experience decision-making. We will also run a social network analysis on 3 colonies from both groups to examine temporal changes in social organization. This will provide us with a mechanistic explanation for how improvements in collective decision-making arise from the actions of individuals. Studying decision-making in ants will allow us to achieve an improved understanding of the development and mechanisms behind expertise.

Depth-specific IOR effect when attention shifts from far to near space relative to viewer

Inhibition of return (IOR) is a phenomenon where responses to a peripheral target are delayed if the target appears more than 300ms in the same location as a previous cue. IOR has been extensively shown to operate in 2D scenes. It is not fully understood whether IOR is determined by relative location between cue and target in retinal coordinates or world coordinates. Such a question can be studied by examining IOR in 3D scenes. We compared IOR when cues and targets appeared at same or different depth planes and when depth information was provided by monocular cues. When the cue and target appeared at different depths, a vertical offset was created on-screen, a potential confound to depth perception. We removed the contribution of this confound by contrasting the 3D condition with a 2D control condition that matched cue and target positions but removed all context simulating 3D space. Results showed that IOR magnitude decreased for the different-depth condition compared to the same-depth condition in 3D displays. IOR magnitude also decreased as a function of vertical offset in corresponding 2D displays. Most importantly, such magnitude reduction in 3D displays was higher than that in the 2D displays, but only when the difference in depth was caused by the target appearing at a nearer position compared to the cue. We thus have identified a depth-specific IOR effect in a setting strictly comprised of monocular depth cues, which occurs only when attention shifts from far to near space relative to the viewer.
