Learning is usually thought to occur during episodes of studying, whereas retrieval of information on testing simply serves to assess what was learned. We review research that contradicts this traditional view by demonstrating that retrieval practice is actually a powerful mnemonic enhancer, often producing large gains in long-term retention relative to repeated studying. Retrieval practice is ...

The regularity lemma is a fundamental result from the extremal graph theory. It is to claim the existence of a regular partition, from which we can construct the reduced graph, hence preserve the consistent behavior inside the same partition, and also decrease the order of input graph significantly. It is a very important tool in theoretical proofs, but due to the requirement of very large grap...

Bumblebees were trained in biologically realistic sensorimotor tasks to test how learnt information from more than a single task is organised in memory. Bees (Bombus impatiens and Bombus occidentalis) learned to collect sucrose solution from the arms of small T-mazes. The reward was offered in the right arm of a maze when the entrance was marked blue, and in the left arm when the entrance was y...

Recovering discrete words from continuous speech is one of the first challenges facing language learners. Infants and adults can make use of the statistical structure of utterances to learn the forms of words from unsegmented input, suggesting that this ability may be useful for bootstrapping language-specific cues to segmentation. It is unknown, however, whether performance shown in small-scal...

Once material has been learned to a criterion of one perfect trial, further study within the same session constitutes overlearning. Although overlearning is a popular learning strategy, its effect on long-term retention is unclear. In two experiments presented here, 218 college students learned geography facts (Experiment 1) or word definitions (Experiment 2). The degree of learning was manipul...

A long-term training paradigm in lipreading was used to test the fuzzy logical model of perception (FLMP). This model has been used successfully to describe the joint contribution of audible and visible speech in bimodal speech perception. Tests of the model were extended in the present experiment to include the prediction of confusion matrices, as well as performance at several different level...

According to Oxford (1990), strategies are steps taken by students to enhance their own learning. This research attempted to investigate the impact of teaching vocabulary learning strategies on short-term and long-term retention of vocabulary items. The sample participants included 303 females randomly selected from one all-female governmental Pre-university school (PUC) in Iran. They were then...

BACKGROUND The aim of this study was to evaluate long-term platinum retention in patients treated with cisplatin and oxaliplatin. METHODS 45 patients, treated 8-75 months before participating in this study, were included. Platinum levels in plasma and plasma ultrafiltrate (pUF) were determined. In addition, the reactivity of platinum species in pUF was evaluated. Relationships between platinu...

Using a simultaneaus discrimination procedure it was shown that pigeons were capable of learning to discriminate 100 different black and white visual patterns from a further 625 similar stimuli, where responses to the former were rewarded and responses to the latter were not rewarded. Tests in which novel stimuli replaced either the rewarded or nonrewarded stimuli showed that the pigeons had no...

Experimental studies have observed Long Term synaptic Potentiation (LTP) when a presynaptic neuron fires shortly before a postsynaptic neuron, and Long Term Depression (LTD) when the presynaptic neuron fires shortly after, a phenomenon known as Spike Timing Dependent Plasticity (STDP). When a neuron is presented successively with discrete volleys of input spikes STDP has been shown to learn 'ea...
