An exemplar-familiarity model predicts short-term and long-term probe recognition across diverse forms of memory search.

Effects of exercise on spatial memory deficits induced by nucleus basalis magnocellularis lesions

Introduction: Previous studies have shown that exercise enhances cognitive and functional capacities in patients with Alzheimer's disease (AD). In this study, we investigated the effect of long-term (60 days) and short- term (10 days) exercise on the spatial memory deficits in an animal model of AD. Methods: Fifty male rats were divided into 5 groups 1) intact, 2) sham, 3) sham-Alzheimer 4) ...

In press: Psychology of Learning and Motivation An Exemplar-Retrieval Model of Short-Term Memory Search: Linking Categorization and Probe Recognition

Short-term memory scanning viewed as exemplar-based categorization.

Exemplar-similarity models such as the exemplar-based random walk (EBRW) model (Nosofsky & Palmeri, 1997b) were designed to provide a formal account of multidimensional classification choice probabilities and response times (RTs). At the same time, a recurring theme has been to use exemplar models to account for old-new item recognition and to explain relations between classification and recogn...

The spatial learning and memory performance in methamphetamine–sensitized and withdrawn rats

Objective(s): There is controversial evidence about the effect of methamphetamine (METH) on spatial memory. We tested the time- dependent effects of METH on spatial short-term (working) and long-term (reference) memory in METH –sensitized and withdrawn rats in the Morris water maze. Materials and Methods: Rats were sensitized to METH (2 mg/kg, daily/5 days, SC). Rats were trained in water maze ...

Speech Emotion Recognition Using Scalogram Based Deep Structure

Speech Emotion Recognition (SER) is an important part of speech-based Human-Computer Interface (HCI) applications. Previous SER methods rely on the extraction of features and training an appropriate classifier. However, most of those features can be affected by emotionally irrelevant factors such as gender, speaking styles and environment. Here, an SER method has been proposed based on a concat...
