About this study

Official title: The Effects of Computerized Cognitive Training on Executive Function in Children in Hong Kong

Specific objectives include:

To assess the effectiveness of CogniFit training on improving executive functions, such as working memory, attention, and inhibitory control in children compared to a waitlist control group.
To assess the effectiveness of CogniFit training on improving executive functions, such as working memory, attention, and inhibitory control in children compared to an active control group that will receive Cogmed training.

Participants will be randomly assigned to one of three groups: 1) the CogniFit training group; 2) the Cogmed Group, and 3) the wailist controlled group.

Participants in the two computerized cognitive training groups (CogniFit/Cogmed Group) will receive training in the first phase of intervention, while the waitlist control group will CogniFit trainings in the second phase of intervention.

Participants who receive the computerized cognitive training will complete 24 sessions of training, 15-20 minutes each, conducted three times per week spanning 8 weeks. These programs comprise a range of game-like exercises targeting various cognitive skills, including working memory, attention, and inhibitory control, with automatic level advancement after each exercise.

To investigate the intervention effectiveness, children will be asked to complete a set of cognitive tests covering inhibitory control, attention, and working memory prior to the intervention (i.e., Time 1), immediately after the 8-week training (i.e., Time 2), and 2 months after the training (i.e., Time 3, a 2-month follow up). The assessment will take around 1 hour and it will be conducted at participants' schools. Also, parents will be asked to complete a questionnaire assessing children's behaviours at home and schools at 3 time points.

Conditions: Executive Function (Cognition)
Being tested: CogniFit Computerized Cognitive Training, Cogmed Computerized Cognitive Training
Keywords: executive function, children, computerized cognitive training, working memory, cognitive function

Where is the study taking place?

The record lists 1 site in Hong Kong. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Executive Functiong - Conners Continuous Performance Test 3rd Edition (CPT 3) (time frame: Pre-intervention Assessment (within 4 weeks before the commencement of the intervention)). The study lists 6 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT06766149.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 Apr 2026.
