Control of fingertip temperature increases via biofeedback in learning-disabled and normal children
Insights
This study shows consistent reinforcement effectively teaches thermal biofeedback to children, with learning-disabled children showing superior control. Younger children and girls also demonstrated better learning outcomes in this thermal biofeedback research.
Area of Science:
- Pediatric Psychology
- Neuroscience
- Educational Psychology
Background:
- Limited research exists on biofeedback effects in children, particularly those with learning disabilities.
- Thermal biofeedback has potential applications in pediatric populations.
Purpose of the Study:
- To assess the effects of thermal biofeedback on children aged 7-9 years.
- To compare the efficacy of consistent versus mixed reinforcement schedules.
- To investigate differences between learning-disabled and normal children.
Main Methods:
- Sixty children (7-9 years) participated, half with learning disabilities and half without.
- A five-day training regimen involved daily 15-minute sessions with thermal biofeedback.
- Two reinforcement conditions were used: consistent and mixed reinforcement for digital temperature increases.
Main Results:
- Children receiving consistent reinforcement showed significantly better learning than those with mixed reinforcement.
- Learning-disabled children demonstrated superior thermal control compared to normal children.
- Younger children and girls generally performed better than older children and boys, respectively.
Conclusions:
- Consistent reinforcement is crucial for effective thermal biofeedback learning in children.
- Thermal biofeedback may be particularly beneficial for enhancing learning in children with learning disabilities.
- Age and sex may influence learning outcomes in pediatric biofeedback interventions.
Abstract:
Although considerable research has been done with biofeedback in adults, little is known of its effect in children of different ages or those with learning disabilities. This study assessed the effects of thermal biofeedback in 60 children (40 boys, 20 girls) aged 7 to 9 yr. (Mage 8-6) half of whom were learning-disabled and half, normal children matched for age, sex, grade, race, socioeconomic status, and IQ. Training consisted on one 15-min. period daily for five days with three trials per period. Children (16 learning-disabled, 16 normals) received consistent reinforcement for digital temperature increases while 28 children (14 learning-disabled, 14 normals) received mixed reinforcement after Day 1, on which all children were consistently reinforced to yield a performance baseline. Feedback was provided by a variable intensity light and toy electric train. Learning was demonstrated only for the consistently reinforced group, which performed almost twice as well as those receiving mixed reinforcement. Learning-disabled children learned thermal control even better than normals, explained in terms of biofeedback reinforcing an internal steady state conducive to learning. Younger children did better than older children, and girls did somewhat better than boys. Post-training improvement in figure-ground discrimination and intersensory-integration was linked with performance and learning, respectively.
