What are the implications of combining verbal self-instruction with variable training for individuals with executive deficits?
What are the implications of combining verbal self-instruction with variable training for individuals with executive deficits?
It indicates that this combination may complicate the training process and affect the amount of transfer to task switching.
How did verbal self-instructions impact near transfer in task-switching training?
How did verbal self-instructions impact near transfer in task-switching training?
Verbal self-instructions did not promote transfer of task-switching training, suggesting limited effectiveness in this context.
What two possible explanations were provided for decreased transfer after variable training in children?
What two possible explanations were provided for decreased transfer after variable training in children?
One explanation is that children used internal verbal strategies similar to overt self-instructions; the other is that a control condition without verbal instructions would be needed for clarity.

Study Notes
Executive Control Training and Age Differences
- Executive control is the ability to plan, guide, and monitor complex actions, a fundamental human ability
- Executive control involves separate components like switching, updating, and inhibition
- Age-related changes in executive control have been observed across the lifespan
- Task-switching paradigms involve alternating between tasks (A and B) in single-task or mixed-task blocks
- Mixing costs are the difference in performance between mixed-task and single-task blocks, reflecting task maintenance
- Switching costs are the difference in performance between switch and non-switch trials in mixed-task blocks, reflecting task-switching ability
- Children and older adults often have larger mixing costs than young adults, though age differences in switching costs are less pronounced
- Training can reduce age-related differences in task-switching costs
- Transfer of training benefits to other tasks or skills is limited and variable
Transfer of Training
- Training can improve performance on structurally similar tasks (near transfer) and dissimilar tasks (far transfer)
- Far transfer can involve tasks from a different domain, like executive control tasks or fluid intelligence
- Verbal self-instruction can enhance near transfer, particularly in children and older adults
- Variable training tasks can also boost near transfer, especially in adults
Training Procedure
- The study utilized a pretest-training-posttest design with three age groups (children, young adults, older adults)
- Participants were assigned to different training groups: single-task training, task-switching training, task-switching + verbal self-instruction training, task-switching + verbal self-instruction + variability training
- Matching was done based on pretest mixing costs and single-task reaction times to avoid baseline differences
- Training sessions involved practice blocks and experimental blocks with different tasks
- Transfer training was assessed using the same task-switching paradigm and other executive tasks
Study Outcomes: Near Transfer
- All age groups showed near transfer of task-switching training to structurally similar tasks
- Transfer was especially evident in children and older adults
- Variability in training tasks enhanced near transfer in adults, but impaired it in children
- Verbal self-instruction did not significantly improve near transfer
Study Outcomes: Far Transfer
- All age groups exhibited substantial far transfer to other executive tasks and fluid intelligence
- This suggests transfer of general executive control skills
- No significant age differences in the far transfer, but further research is required
