Trigrams were presented visually or auditorily and followed by a 12 s retention interval filled with shadowing numbers or letters. Auditory memory letters followed by letter shadowing were recalled less than auditory memory letters followed by number shadowing or visual memory letters followed by either type of shadowing. The latter three conditions did not differ among themselves. An analysis of the recall intrusions suggested that forgetting of auditory memory letters followed by letter shadowing was caused mainly by a confusion between covert rehearsals and shadowing activity, while forgetting in the other three conditions was caused primarily by proactive interference from earlier memory trials.

Prior Item

The experiment was conducted to examine the effect of prior-item retention interval on the retention of a given item in a short-term memory test series. There were five conditions. The retention interval for the fifth test of five successive tests was 15 sec. for all five conditions. The retention intervals for tests 1–4 were constant for a condition but varied across conditions. These retention intervals were 5, 10, 15, 20 and 25 sec. Five consonant trigrams constructed from the set of letters sharing the vowel sound “e” were used for all conditions. Recall on test 5 was a direct function of prior-item retention interval. The data indicate, therefore, that the availability of prior items for proactive interference is an inverse function of prior-item retention interval.

Background: Short-term memory allows recall for a period of several seconds to a minute without rehearsal. Various studies have shown a positive correlation between physical activity and cognition. The present study is undertaken to find out if physical training has any extra benefit on children’s auditory and visual short term memory in rural area whose physical activity is greater than urban children and adults. Materials and methods: Total 60 children participated in the study. 30 children were trained regularly in sports both in the morning and evening at least for 2 hours a day for one year in the age group of 8-16 and 30 untrained children age, gender and BSA matched participated in the study. Auditory memory was tested using numerical and word test. Visual memory was tested using numerical, word and objective tests. Results and discussion: Statistically significant results were observed in auditory word test, visual numerical, visual word and visual objective tests but auditory numerical test was insignificant. Conclusions: Short term memory improves linearly with physical activity. This could be due to increase in supply of oxygen and nutrients to brain.

Draft version 28.03.2020. This paper has not been peer reviewed. Please do not copy or cite without author's permission. Short-term memory has mostly been investigated with verbal or visuospatial stimuli and less so with other categories of stimuli. Moreover, the influence of sensory modality has been explored almost solely in the verbal domain. The present study used the same experimental paradigm to investigate auditory and visual short-term memory for different types of stimuli. In each trial, participants were presented with two sequences of events, separated by a silent delay, and had to indicate whether the two sequences were identical or different. Performance in this recognition (delayed-matching-to-sample) paradigm was compared for materials that were either verbal (i.e., chained syllables without meaning) or nonverbal (i.e., not easily described by verbal labels). For the latter ones, the event sequence could either entail a contour, which is a pattern of up and down changes (based on non-pitch features), or not. All materials were implemented in both auditory and visual modalities. As previous research has reported better auditory memory (and to some extent, visual memory), and better auditory contour recognition for musicians than non-musicians, the recognition tasks were performed by a group of musicians and a group of non-musicians. Results revealed a selective advantage of musicians for the auditory no-contour stimuli and for the contour stimuli (both visual and auditory), suggesting that musical expertise is associated with specific short-term memory advantages in domains close to the trained domain, even extending cross-modally. These findings offer new insights into the role of encoding strategies and their effect on short-term memory performance across modalities.

AbstractShort-term memory has mostly been investigated with verbal or visuospatial stimuli and less so with other categories of stimuli. Moreover, the influence of sensory modality has been explored almost solely in the verbal domain. The present study compared visual and auditory short-term memory for different types of materials, aiming to understand whether sensory modality and material type can influence short-term memory performance. Furthermore, we aimed to assess if music expertise can modulate memory performance, as previous research has reported better auditory memory (and to some extent, visual memory), and better auditory contour recognition for musicians than non-musicians. To do so, we adapted the same recognition paradigm (delayed-matching to sample) across different types of stimuli. In each trial, participants (musicians and non-musicians) were presented with two sequences of events, separated by a silent delay, and had to indicate whether the two sequences were identical or different. The performance was compared for auditory and visual materials belonging to three different categories: (1) verbal (i.e., syllables); (2) nonverbal (i.e., that could not be easily denominated) with contour (based on loudness or luminance variations); and (3) nonverbal without contour (pink noise sequences or kanji letters sequences). Contour and no-contour conditions referred to whether the sequence can entail (or not) a contour (i.e., a pattern of up and down changes) based on non-pitch features. Results revealed a selective advantage of musicians for auditory no-contour stimuli and for contour stimuli (both visual and auditory), suggesting that musical expertise is associated with specific short-term memory advantages in domains close to the trained domain, also extending cross-modally when stimuli have contour information. Moreover, our results suggest a role of encoding strategies (i.e., how the material is represented mentally during the task) for short-term-memory performance.

Cognitive Memory

In the field of neuroscience, cognitive memory is at the center of biomedical research. Prior works in cognitive memory all suggest and show that as people age their short term memory slows down and becomes less effective from an accuracy standpoint. This especially becomes apparent in age related memory impairments such as Alzheimer’s. Using musical stimulation this study was focused on finding out if music has an effect on a musician’s short term memory speed and overall accuracy in both auditory and visual memory. Visual and auditory memory are the primary ways in which music is memorized. Along with visual memory motor memory is also tested in musicians as they use muscles when playing an instrument (Chua,  2014). Thus, these two were combined with the aim of finding out if music has an effect on the entire short term memory system. The study focused on all ages ranging from fourteen to the age bracket of sixty and over. Each participant was given the same conditions under which the study was conducted. Using a T-chart analysis the data showed that overall the speed of memory is enhanced with musical stimulation; however, accuracy was statistically insignificant. To avoid the distraction of future participants they should be evaluated one at a time.Key Words: cognitive memory, auditory, visual, musicians, motor memory

Machine Learning Models

In this paper, we propose a prediction algorithm, the combination of Long Short-Term Memory (LSTM) and attention model, based on machine learning models to predict the vision coordinates when watching 360-degree videos in a Virtual Reality (VR) or Augmented Reality (AR) system. Predicting the vision coordinates while video streaming is important when the network condition is degraded. However, the traditional prediction models such as Moving Average (MA) and Autoregression Moving Average (ARMA) are linear so they cannot consider the nonlinear relationship. Therefore, machine learning models based on deep learning are recently used for nonlinear predictions. We use the Long Short-Term Memory (LSTM) and Gated Recurrent Unit (GRU) neural network methods, originated in Recurrent Neural Networks (RNN), and predict the head position in the 360-degree videos. Therefore, we adopt the attention model to LSTM to make more accurate results. We also compare the performance of the proposed model with the other machine learning models such as Multi-Layer Perceptron (MLP) and RNN using the root mean squared error (RMSE) of predicted and real coordinates. We demonstrate that our model can predict the vision coordinates more accurately than the other models in various videos.

This study investigated the encoding strategies employed by Chinese and English language users when recalling sequences of pictured objects. The working memory performance of native English participants (n = 14) and Chinese speakers of English as a second language (Chinese ESL; n = 14) was compared using serial recall of visually-presented pictures of familiar objects with three conditions: (i) phonologically and visually distinct, (ii) phonologically similar and visually distinct, and (iii) phonologically distinct and visually similar. Digit span, visual pattern span and articulation rate were also measured. Results indicated that whilst English participants were affected by the phonological but not the visual similarity of items, the performance of Chinese ESL participants was comparable across all three conditions. No significant differences in digit span, visual memory or articulation rate were found between groups. These results are discussed in the light of our understanding of the use of cognitive resources in short-term memory in users of diverse orthographies.
