Episodic memory impairment is a hallmark for early diagnosis of Alzheimer's disease. Most actual tests used to diagnose Alzheimer's disease do not assess the spatiotemporal properties of episodic memory and lead to false-positive or -negative diagnosis. We used a newly developed, nonverbal navigation test for Human, based on the objective experimental testing of a spatiotemporal experience, to ...

Haptics is a feedback technology that takes advantage of the human sense of touch by applying forces, vibrations, and/or motions to a haptic-enabled user device such as a mobile phone. Historically, human–computer interaction has been visual, data, or images on a screen. Haptic feedback can be an important modality in Mobile Location-Based Services like – knowledge discovery, pedestrian navigat...

Spatial memory is an important facet of human cognition – it allows users to learn the locations of items over time and retrieve them with little effort. In human-computer interfaces, knowledge of the spatial location of controls can enable a user to interact fluidly and efficiently, without needing to perform slow visual search. Computer interfaces should therefore be designed to provide suppo...

How can the observations of spatial blocking (Rodrigo, Chamizo, McLaren & Mackintosh, 1997) and cue redundancy (O’Keefe and Conway, 1978) be reconciled within the framework provided by an error-correcting, connectionist account of spatial navigation? I show that an implementation of McLaren’s (1995) better beta model can serve this purpose, and examine some of the implications for spatial learn...

We describe a spatial navigation model that uses a hierarchical representation of space. The model is able to explore exhaustively large environments and to plan paths between distant places, even though it uses a working memory with a limited capacity. By using a hierarchical structure, an agent with a limited working memory capacity has (a) a comparable performance to that of an agent with no...

Perspectives on human spatial cognition: Memory, navigation, and environmental learning (Michel Denis & Jack M. Loomis) Humans do not switch between path knowledge and landmarks when learning a new environment (Patrick Foo, Andrew Duchon, William H. Warren, Jr., & Michael J. Tarr) Using geometry to specify location: Implications for spatial coding in children and nonhuman animals (Stella F. Lou...

The hippocampus is crucial for both spatial navigation and episodic memory, suggesting that it provides a common function to both. Here we adapt a spatial paradigm, developed for rodents, for use with functional MRI in humans to show that activation of the right hippocampus predicts the use of an allocentric spatial representation, and activation of the left hippocampus predicts the use of a se...

Avian hippocampal function is surveyed, using data drawn from three areas: conventional laboratory paradigms, pigeon navigation, and food-storing. Damage to the avian hippocampus disrupts performance in laboratory tasks that tap spatial learning and memory, and also disrupts both pigeon homing and cache recovery by food-storing birds. Further evidence of hippocampal involvement in food-storing ...

The aim of this study was to explore the effects of preoperative and postoperative lateralized mesial temporal damage on three measures of spatial learning: navigation, object location and plan drawing, and to determine the relationship between volumetry of the hippocampus and memory performance. Fifteen patients with well-characterized unilateral hippocampal sclerosis, 15 patients who had unde...
