There are two complementary approaches to characterizing performance in a free recall task (retrieving items from a specified category). The historic, or top down approach, considers the overall structure of the produced responses, generally as the parameters of a fitted cumulative recall curve. Alternatively, free recall can be considered as a time series(More)
Foraging is a search process common to mobile organisms, and foraging paths commonly exhibit statistical patterns akin to Lévy walks. There may be common factors and benefits underlying these patterns, but investigations are hindered by difficulty in assessing and manipulating search environments and task conditions. In the present study, a simple foraging(More)
Scaling laws are ubiquitous in nature, and they pervade neural, behavioral and linguistic activities. A scaling law suggests the existence of processes or patterns that are repeated across scales of analysis. Although the variables that express a scaling law can vary from one type of activity to the next, the recurrence of scaling laws across so many(More)
Eyes move to gather visual information for the purpose of guiding behavior. This guidance takes the form of perceptual-motor interactions on short timescales for behaviors like locomotion and hand-eye coordination. More complex behaviors require perceptual-motor interactions on longer timescales mediated by memory, such as navigation, or designing and(More)
Eye movements gather visual information from the environment for various purposes and goals. Spatial patterns of eye movements vary depending on the layout of visual information, and intentions of the observer. However, despite this variability, basic principles of visual information gathering may be reflected in lawful properties of eye movement(More)
We present a study aimed at investigating how novel signs emerge and spread through a community of interacting individuals. Ten triads of participants played a game in which players created novel signs in order to communicate with each other while constantly rotating between the role of interlocutor and that of observer. The main result of the study was(More)
A scaling law (a.k.a. power law) occurs in nature when one observed variable x is a function of another, raised to some power α: f(x) = ax α. A well-known example from biology is the allometric scaling law relating metabolic rate and body mass across species (Brown & West, 2000). Scaling relations are scale invariant, which means that multiplying x by a(More)
The extent to which a cognitive system’s behavioral dynamics fit a power law distribution is considered indicative of the extent to which that system’s behavior is driven by multiplicative, interdependent interactions between its components. Here, we investigate the dynamics of memory processes in individual and collaborating participants. Collaborative(More)

We present the results of two temporally extended experimental implementations of the Monty Hall dilemma in order to examine the dynamics of belief. In the first experiment, we used the standard three-door version of the dilemma, but biased the probability of the winning door positionally. Participants capitalized on the increased probabilities but did not(More)
