Exclusivity and memory for object location
Baguley et al. (2006) have demonstrated that location memories are retrieved exclusively: when a person has two or more memories for an object’s location (which show the same object from different perspectives), only one representation can be retrieved at any one time. Whilst this finding is …

Investigating the Role of Dopamine D1 Receptor Activation in Overcoming Boundary Conditions for Object Identity and Object Location Memory Malleability
… contextual updating, of relatively remote object identity and object location memories. Systemic D1R agonist SKF38393 was sufficient to induce destabilization of relatively remote object identity and object location memories. Lastly, object identity memory and object location memory …

The function and structure of the entorhinal cortex in mild cognitive impairment
… EC are involved respectively in navigation and object-location memory. The advent of immersive VR (iVR) technology provides an opportunity to determine whether tests of pmEC and alEC function has value in the detection of AD prior to dementia onset. Aim: To test the hypotheses that measures of …

Role of torque in haptic perception of virtual objects
… role of torque feedback in haptic perception of object location within virtual environments. The experimental setup consisted of two Phantom haptic interfaces connected by a common stylus and a raybased rendering technique for modeling the interactions between the user-controlled stylus and the …

The role of expertise, semantics, and learning in spatial memory
… investigates the mechanisms that underpin object location memory. It approaches this endeavour by examining a recently reported phenomenon of spatial memory, that of exclusivity. Exclusivity states that given the opportunity to encode or retrieve two spatial memories, only one memory is …

The neural correlates of Human Spatial Memory and Representation
The importance of object-location memory for our everyday survival is now well accepted. This behaviour relies on spatial representation and memory within the brain. With these representations, we are able to construct what has been described as a “cognitive map” (Tolman, 1948) that allows us to …

The effect of exercise on spatial learning and hippocampal proteins in maternally separated adult rats
… Previously, we reported that MS improved object location memory. However, exercise had no effect on object location memory despite increases in levels of synaptophysin and phospho-extracellular signal-regulated protein kinase (pERK) in the hippocampus of non-separated-exercised rats. In …

Learning commonsense human-language descriptions from temporal and spatial sensor-network data
… hands or turning a doorknob. Sensors placed on objects in the environment now report many parameters, including object location, movement, sound, and temperature. A persistent problem, however, is the description of these sense data in meaningful human-language. This is an important problem that …

The role of attention in spatial (dis)orientation of older adults.
… pronounced when recognition depended on object- location binding mechanisms to encode the spatial arrangements of landmarks, as compared to recognition from object identity alone. Analyses of eye-tracking data revealed a specific visual encoding strategy which involved linking landmarks …

An approach to building a secure and persistent distributed object management system
The Common Object Request Broker Architecture (CORBA) proposed by the Object Management Group (OMG) is a widely accepted standard to provide a system level framework in design and implementation of distributed objects. The core of the Object Management Architecture (OMA) is an Object Request Broker …

Energy-Efficient Tracking in Sensor Networks
We consider the problem of tracking one or more objects in an energy-efficient manner using a sensor network. The sensors in this network can enter an asleep mode where they conserve energy but are unable to help track the objects. We consider two assumptions for how the sleeping actions of the …

Automatic Positioning and Design of a Variable Baseline Stereo Boom
… However, large baselines have problems whenever objects approach the cameras. The objects begin to leave the field of view of the cameras, making it impossible to determine where they are located in 3D space. This becomes especially important if an object of interest must be actuated upon and is …

The effects of licorice root components on cognition
… task, a hippocampus-sensitive metric change in object location (MCOL) task and a striatum-sensitive double object recognition (DOR) task. Isoliquiritigenin (ISL), licorice root extract (LRE), and whole licorice root powder (LRP) were assessed. ISL is a pure compound found in licorice root with …

The relationship between encoding and recall for the identities and locations of objects
… number of fixations that participants made on objects in a photograph of a visual scene and the memory that participants exhibited for the identities and locations of those objects. The results of Experiment 1 showed that there is a very close relationship between encoding and recall for both …

Predictive Duty Cycling of Radios and Cameras using Augmented Sensing in Wireless Camera Networks

On foveation of deep neural networks
The human ability to recognize objects is impaired when the object is not shown in full. "Minimal images" are the smallest regions of an image that remain recognizable for humans. [26] show that a slight modification of the location and size of the visible region of the minimal image produces a …
