Summary
This study shows that working memory (WM) training significantly improved WM performance in children with cochlear implants (CIs). These findings suggest WM training can aid in the rehabilitation of implanted children.
Area of Science:
- Neuroscience
- Cognitive Psychology
- Audiology
Background:
- Sensory deprivations, like hearing impairment, negatively impact cognitive functions, including working memory (WM).
- Children with cochlear implants (CIs) often exhibit deficits in WM, which is crucial for language processing.
- Understanding WM in CI users is vital for effective educational and rehabilitative strategies.
Purpose of the Study:
- To evaluate the efficacy of a working memory (WM) training program in children with cochlear implants (CIs).
- To assess changes in auditory WM performance before and after a targeted WM intervention.
Main Methods:
- Twenty-five children (ages 7-10) with CIs participated.
- A computer game-based program was used for WM training.
- Auditory WM was assessed using digit span (forward/backward), non-word repetition, and sentence repetition tests pre- and post-training.
Main Results:
- Statistically significant improvements were observed in all WM subtest scores post-training.
- Specific significant gains were noted in forward digit span (P=0.003), backward digit span (P=0.001), non-word repetition (P=0.001), and sentence repetition (P=0.003).
Conclusions:
- Working memory (WM) training can effectively enhance WM capacity in children with cochlear implants (CIs).
- Implementing WM intervention programs may benefit the literacy and learning development of implanted children.
- WM training shows promise as a valuable tool in the rehabilitation of children with CIs.

Clinical trials are prospective experimental studies conducted on humans to determine the safety and efficacy of treatments, drugs, diet methods, and medical devices. Using statistics in clinical trials enables researchers to derive reasonable and accurate conclusions from the collected data, allowing them to make wise decisions in uncertain situations. In medical research, statistical methods are crucial for preventing errors and bias.

Clinical development focuses on how the drug will interact with the human body and encompasses four key phases of clinical trials, each serving a specific purpose in assessing the safety and effectiveness of new drugs. These phases overlap and build upon one another. Phase I involves a small group of healthy volunteers (typically 20-80 individuals) or, in cases where significant toxicity is expected, patients with the targeted disease, such as cancer or AIDS. The volunteers are tested for...

The air in the lungs is measured in volumes and capacities. Lung volume measures reflect the amount of air taken in, released, or left over after a lung function, like a single inhalation. Lung capacity measures are sums of two or more lung volume measures.

A problem-solving strategy is a plan of action used to find a solution. Different strategies have distinct action plans. Trial and error involves trying different solutions until one works. For instance, to fix a broken printer, you might check ink levels, ensure the paper tray isn't jammed, and verify the printer's connection to your laptop. This method can be time-consuming but is commonly used. Thomas Edison, for example, used trial and error to find a suitable filament for the light...
