Brief Summary

This study aims to address these gaps by conducting a comprehensive evaluation of the effects of CogniFit training in children. The primary objective of this study is to evaluate the effectiveness of CogniFit training on executive functions among primary school students in Hong Kong. Specific objectives include:

1. 1.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.
2. 2.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.

Outcome Measures

Primary Outcomes (6)

• Executive Functiong - Conners Continuous Performance Test 3rd Edition (CPT 3)

  A standardized computerized test on sustained attention and inhibitory control

  Pre-intervention Assessment (within 4 weeks before the commencement of the intervention)

• Executive Functiong - Conners Continuous Performance Test 3rd Edition (CPT 3)

  A standardized computerized test on sustained attention and inhibitory control

  Immediate Post-intervention Assessment (within 4 weeks after the completion of the intervention)

• Executive Functiong - Conners Continuous Performance Test 3rd Edition (CPT 3)

  A standardized computerized test on sustained attention and inhibitory control

  Delayed Post-intervention Assessment (a 2-month follow up after the completion of the intervention)

• Executive Function - Number subtest of Children's Memory Scale (CMS)

Study Arms (3)

CogniFit Group

EXPERIMENTAL

The CogniFit training group will receive 24 sessions of training, 35 - 40 minutes each, conducted three times per week over a period of 8 weeks. Participants will be asked to complete a set of computerized tasks using CogniFit, a digital training programme which is proven to enhance cognitive ability of participants.

Behavioral: CogniFit Computerized Cognitive Training

Cogmed Group

ACTIVE COMPARATOR

The Cogmed training group will receive 24 sessions of training, 35 - 40 minutes each, conducted three times per week over a period of 8 weeks. Participants will be asked to complete a set of computerized tasks using Cogmed, a digital training programme which is proven to enhance working memory and attentional control of participants.

Behavioral: Cogmed Computerized Cognitive Training

Waitlist Control Group

NO INTERVENTION

The waitlist control group will not receive any intervention until the intervention arms complete their training. After completion of the assessment at Timepoint 3, Computerized Cognitive Training will be offered to this group.

Interventions

CogniFit Computerized Cognitive Training BEHAVIORAL

In the CogniFit Computerized Cognitive Training, children will complete a range of tasks covering a range of game-like exercises targeting various cognitive skills, including working memory, attention, and inhibitory control, with automatic level advancement after each exercise.

CogniFit Group

Cogmed Computerized Cognitive Training BEHAVIORAL

In the Cogmed Computerized Cognitive Training, children will complete a range of tasks covering a range of game-like exercises targeting various cognitive skills, including working memory and attentional control, with automatic level advancement after each exercise.
