Episodic memory refers to the recollection of a representation that binds together into a unique past experience "what" happened, "where" and "when". Sleep has been identified as a state that optimizes the consolidation of newly acquired memory. To determine if sleep is important for the consolidation of episodic-like memory, we tested rats on an episodic-like memory task requiring the binding ...

Two experiments examined effects of aging on implicit and explicit memory for novel visual objects. Implicit memory was assessed with an object decision task in which subjects indicated whether briefly exposed drawings represented structurally possible or impossible objects. Explicit memory was assessed with a yes-no recognition task. On the object decision task, old and young subjects both sho...

Object recognition is achieved through neural mechanisms reliant on the activity of distributed neural assemblies that are thought to be coordinated by synchronous firing in the gamma-band range (>20 Hz). An outstanding question focuses on the extent to which the role of gamma oscillations in object recognition is dependent on attention. Attentional mechanisms determine the allocation of percep...

Our object recognition abilities, a direct product of our experience with objects, are fine-tuned to perfection. Left temporal and lateral areas along the dorsal, action related stream, as well as left infero-temporal areas along the ventral, object related stream are engaged in object recognition. Here we show that expertise modulates the activity of dorsal areas in the recognition of man-made...

Recognising objects in everyday human environments is a challenging task for autonomous mobile robots. However, actively planning the views from which an object might be perceived can significantly improve the overall task performance. In this paper we have designed, developed, and evaluated an approach for next best view planning. Our view planning approach is based on online aspect graphs and...

The present study investigated implicit and explicit recognition processes of rapidly perceptually learned objects by means of steady-state visual evoked potentials (SSVEP). Participants were initially exposed to object pictures within an incidental learning task (living/non-living categorization). Subsequently, degraded versions of some of these learned pictures were presented together with de...

Mainstream object detectors are commonly constituted of two sub-tasks, including classification and regression tasks, implemented by parallel heads. This classic design paradigm inevitably leads to inconsistent spatial distributions between score localization quality (IOU). Therefore, this paper alleviates misalignment in the view knowledge distillation. First, we observe that massive teacher a...

Visual perception is based on information processing during periods of eye fixations that are interrupted by fast saccadic eye movements. The ability to sample and relate information on task-relevant objects across fixations implies that correspondence between presaccadic and postsaccadic objects is established. Postsaccadic object information usually updates and overwrites information on the c...

This study attempts to generalize Biederman's 1987 findings regarding Recognition by Components theory, which were obtained using a computer administered object-recognition task, to an analog or paper task that is consistent with typical assessment or testing procedures. Three versions of an object-recognition task were developed after the Structure of Intellect-Learning Abilities Test by Meeke...

There is increasing focus on the role of the nucleus accumbens (NAc) in learning and memory, but there is little consensus as to how the core and medial shell subregions of the NAc contribute to these processes. In the current experiments, we used spontaneous object recognition to test rats with 6-hydroxydopamine lesions targeted at the core or medial shell of the NAc on a familiarity discrimin...
