Fall 2018
Reorientation is an important behavior for humans and non-human animals in everyday life. To determine one’s orientation, navigators could use various cues in the environment. Studies on competition and combination of multiple cues are quite diverse. In this dissertation, I first introduced three...

Fall 2017
This study investigated whether people can develop a global representation of local environments by path integration. Participants learned objects’ locations in two misaligned rectangular rooms in an immersive virtual environment. After learning, they adopted a local view in one room and judged...

Fall 2020
Spatial navigation updates people’s self-location (heading and position) and meanwhile develops spatial memory. Environments in real life are often multiscale environments, which contain a number of individual spaces separated by boundaries. People primarily rely on visual cues (piloting) to...

Fall 2018
Previous research has provided a lot of evidence about spatial navigation on 2D surfaces whereas how animals represent space in 3D navigation involving vertical information is much less often investigated (Jeffery, Jovalekic, Verriotis, & Hayman, 2013; Jeffery, Wilson, Casali, & Hayman, 2015)....

From Scattering Dots to Cognitive Maps: Contributions of visual features in localization and cognitive mapping
DownloadFall 2016
Localizing oneself and other objects in an environment is important in everyday life. Various visual features available in our surroundings can serve as spatial cues to support accurate localization. Encoding individual locations can be achieved by establishing a vector between a target location...

Path integration, rather than being suppressed, used to update spatial views in familiar environments with landmarks always available
DownloadFall 2023
This project, following the elegant paradigm developed by Zhao and Warren (2015b), investigated how self-motion cues and landmarks are used during navigation in a familiar environment with constantly available landmarks. Participants learned the location of a specific object. After completing one...

The Interaction of Path Integration Cues and Landmarks in Positioning Estimations During Human Spatial Navigation in Small- and Large-scale Environment
DownloadSpring 2018
People use landmarks and the path integration cues to return to the origin of the route (i.e., home). This homing behavior is believed to be better when people can access both cues than when they can only access either cue, because two separate homing estimations are combined to reduce homing...

Spring 2024
An effective navigation process requires the ability to determine the navigators’ current position and heading in the environment (referred to as self-localization) and localize the points of interest, such as home. Humans and non-human animals typically use self-motion cues (i.e., path...
