Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
This research will test the efficacy of a computerised cognitive training program. The training program runs 5 days per week for 6.5 weeks with 1 x 20 minute session per day. The training will be completed in a classroom with the researcher providing instructions and supervising administration. Progress of individual participants can be monitored by the researcher using an online portal.

The training program involves the completion of a number of game-like cognitive training programs (e.g. selecting a picture that matches a pre-determined rule; selecting coloured balls based on a pre-determined rule; selecting an appropriate card to complete a pattern).

One year after the training is completed, the whole training process is completed over again using the same procedure as outlined above.

Other interventions
Comparator / control treatment
A computerised touch-typing training program as the control group intervention. The program instructs participants how to touch-type using the correct posture and finger position. It is a graded program that begins with the easier keys and progresses to more complex typing tasks (e.g. capital letters, numbers and symbols).

The control group intervention runs in the same manner as the experimental group: 5 days per week for 6.5 weeks with 1 x 20 minute session per day. The training will be completed in a classroom with the researcher providing instructions and supervising administration. Progress of individual participants can be monitored by the researcher using an online portal.

One year after the training is completed, the whole training process is completed over again using the same procedure as outlined above.

Efficacy
Statistical methods / analysis
Previous research using sample sizes of 20-30 for the experimental group has found effect sizes for near transfer (i.e. working memory) in the range 0.41 to 4.66. However, the same sample sizes for far transfer (i.e. academic achievement, fluid reasoning) have found non-significant (p>0.05) small effect sizes (~0.25). It has been suggested that this is due to small sample sizes and a lack of power. Therefore, this research will use larger sample sizes to pick up the effect of training on far transfer.

Data analysis will determine if there is a treatment effect on executive function dependent variables by using latent growth modelling. Latent growth models use structural equation modelling techniques to model trajectories of change, assess effects of treatment, and consider the relationships among multiple outcome variables and multiple time points simultaneously (Stull et al., 2011). As outlined by Muthen and Curran (1997), the effect of treatment is assessed by comparing the set of trajectories in the treatment population with those in the control population.

Summary
Brief summary
This research aims to test the efficacy of a computerised, adaptive, cognitive training program by looking at near-transfer to executive function components and far-transfer to higher order cognitive abilities (fluid intelligence and academic achievement).

This research will address previous criticisms of the existing cognitive training literature by: (a) using a cognitive training program that is more aligned to current executive function theory than previous research, by training executive level processes; (b) using multiple measures for each executive function construct to estimate latent scores of executive functions; (c) using randomly allocated experimental and active control groups that utilise similar computer-based tasks and have the same face-to-face contact time so that a realistic comparison can be made as to the efficacy of the cognitive training program; (d) determining the impact of cognitive training on executive functions, fluid intelligence and academic achievement by following a cohort of children over a period of one year; (e) measuring processing speed to determine if this is a potential mediating variable in cognitive training; and (f) assessing the impact of different training expectancies between the experimental and control group and its impact upon training gains. In addition to these student-based measures, behaviourally- based reports from teachers and parents will provide additional sources of evidence of the program’s effects. Lastly, the potential moderating effect of an individual's implicit theory of intelligence on training gains will be assessed.
