Gesture signs in social interaction: how group size influences gesture communication
This thesis explores the effects of group size on gesture communication. Signs in general change, in the kind of information they convey and the way in which they do so, and changes depend on interactive communication. For instance, speech is like dialogue in smaller groups but like monologue in …

Group size, group structure and student interaction in children's computer learning
… skills was examined in relation to group size. Also analyzed were students’ interaction in small groups and the structure of those groups. Sixty-six second-grade students in solo, pair, or triad treatment conditions were given a pretest and equivalent-form posttest. The computer task …

Group size affects predation risk and foraging success in Pacific salmon at sea
Grouping (schooling, flocking, herding) is broadly distributed across taxa and environments, and is particularly common in marine fishes. A rich body of theory outlines ways in which grouping can enhance individual fitness, especially by improved predator avoidance and foraging efficiency. However, …

Group size and proximity effects on computer-mediated idea generation: A laboratory investigation.
This dissertation investigated the effects of group size, group member proximity and the interaction of these two variables on the performance of brainstorming groups in a synchronous, computer-mediated environment. A laboratory experiment was employed to manipulate the independent variables group …

The more the merrier? : understanding the effect of group size on collective intelligence
This dissertation explores how group size affects collective intelligence. It is composed of three quantitative studies. The first study explores how time pressure in small groups (size 4) and large groups (size 20) affected collective intelligence. The results showed that the large groups …

Effect of Group Size on the Activity Budget of Two Captive Chimpanzees (<i>Pan troglodytes</i>)
… Chimpanzees are social creatures and changes in groups as well as relocation to a facility with new social partners, can impact each individual chimpanzee’s welfare. By tracking each chimpanzee’s activity budgets, managers can assess welfare and make improvements or adjustments if necessary. I …

Scanning-group-size effect in flocks of house sparrows : quantifying the contribution of competition and anti-predatory vigilance
As social foraging groups increase in size, individual levels of scanning decrease while time spent feeding increases. Traditionally, anti-predatory considerations provide the preeminent explanation for this scanning-group-size effect, but contest and scramble competition could also account for the …

Essays on Contest Theory Experiments and Revealed Time Preference Models
… of essays, we study the influence of weight and group size in the sequential multi-battle contest with laboratory experiences (Chapter 2 and Chapter 3). We then develop an empirical method to model perceptual present and time inconsistency (Chapter 4). Chapter 2 examines how the weight and the …
