Relational Skills and Intelligence:
Developing a Functional Account of Intellectual
Performance and its Enhancement.
PhD thesis, National University of Ireland Maynooth.
Abstract
Recent research has implicated the potential utility of reconceptualising general
intelligence as representing proficiency in a behavioural skillset known as relational
responding. Indeed, a growing literature base proposes that many of the competencies
that are traditionally conceived to comprise ‘intelligence’ can actually be understood
from this more functional perspective. In addition, as these relational skills are
inherently malleable and open to amelioration, a number of analyses have suggested
that intellectual function can be improved by training and targeting these skills. In light
of this emerging research stream, the current thesis entailed two primary aims: 1) to
assess the efficacy of relational skills training in improving intellectual and academic
performance and 2) to further investigate the relationship between the wider range of
relational frames and intellectual function as a potential means of developing a
functional alternative to traditional IQ assessments based on behaviour-analytic
principles.
In Experiment 1, the efficacy of the SMART program in significantly improving
relational responding proficiency was confirmed, using a large sample of Irish
secondary school students. Experiment 2 extended upon this finding by analysing the
utility of this program in improving intellectual performance using a single-blind
randomised controlled trial, reporting significant gains in Full-Scale, Verbal and
Performance IQ.
As pre-intervention levels of relational ability were found to be an important
determinant of post-intervention outcomes, Experiment 3 endeavoured to further
investigate this pattern by administering SMART to the youngest, normally-developing
sample to date using a crossover design. Statistical analyses revealed the apparent
delimiting impact of low levels of intellectual ability at baseline, with only a small
proportion of the sample completing the training program within a 4-month period. In
light of this finding, Experiment 4 represented the first analysis of the SMART:
Remedial system, a training protocol specifically designed to establish the arbitrarily
applicable relational skills deemed prerequisite for the main SMART program, as a
means of allowing younger children, and those with lower levels of relational
skill/intellectual performance to access the benefits the SMART program may provide.
Results indicated that such skills were successfully established in a sample of children
presenting with additional educational needs and below-average IQ.
Due to the recurrent finding that SMART is an efficacious means of improving
intellectual function, Experiment 5 assessed the impact of this training on academic
performance in a large sample of secondary school students. SMART was found to
produce significant improvements on the Irish Department of Education’s academic
aptitude assessment of choice, the Drumcondra Reasoning Tests.
Experiments 6 & 7 aimed to elucidate the relationship between specific frames
of relational responding and intellectual skills by administering two relational skills
assessments alongside gold-standard metrics of intellectual performance. Such analyses
identified the relational frames of coordination, opposition and comparison as being
most closely associated to intellectual function. In addition, such analyses provide
important insights into the role of analogical and deictic relational responding in
intellectual performance.
The results of the current thesis combine to suggest that relational skills
interventions may facilitate potentially life-changing improvements in both intellectual
and academic performance at a level of magnitude and consistency that has not been
replicated by other ‘cognitive enhancement’ protocols. In addition, the insights gleaned
from the current set of analyses add further weight to the suggestion that intelligence
may be reconsidered as a clearly-defined, functionally-understood, and malleable
behavioural repertoire, rather than an invariant, trait-based, mentalistic construct.
