Here we tested whether the well-known superiority of spaced training over massed training is equally evident in both object identity and object location recognition memory. We trained animals with objects placed in a variable or in a fixed location to produce a location-independent object identity memory or a location-dependent object representation. The training consisted of 5 trials that occu...

The hippocampal formation (HF) functions in two domains of memory: spatial and nonspatial associative memory. The HF includes the hippocampus proper, the dentate gyrus, and the subicular complex. Studies of spatial correlates of HF neuronal activity have revealed that a subject's location in space can impose critical constraints on patterns of neuronal activity in the HF. This report compares m...

In this paper we propose a method for tracking a video object in an ordered sequence of two-dimensional images, where the outcome is the trajectory of the video object throughout the time sequence of images. This method is designed to run in real-time in a synchronous video collaboration environment, and used for producing dynamic object annotations for enhanced video content understanding. A d...

With a growing trend toward a world where people, computers, vehicles, and other mobile objects are interconnected at all times, it is no surprise that tracking the location of these objects and performing computation on such location data are also attracting interest. The idea of location-based services has captured the imagination of application developers, wireless service providers, and con...

Inhibition of Return (IOR) is effective in a wide range of experimental settings but has proven elusive under conditions of volitional (endogenous) attentional control. This result may be due to a continuing attentional bias towards the cued location. Here we ask whether IOR can be unmasked under endogenous cueing conditions when a predictive cue prevents such a bias. In Experiment 1, a central...

In this study, the influence of two types of language on memory for object location was investigated: demonstratives (this, that) and possessives (my, your). Participants read instructions (containing this/that/my/your/the) to place objects at different locations. They then had to recall those object locations. Experiments 1 and 2 tested the contrasting predictions of two possible accounts of l...
