Testing the differentiation of personality by intelligence hypothesis

In some cases your data might already be ranked, but often you will find that you need to rank the data yourself (or use to do it for you). Thankfully, ranking data is not a difficult task and is easily achieved by working through your data in a table. Let us consider the following example data regarding the marks achieved in a maths and English exam:

Grammy-nominated songwriter and music producer, Nana Kwabena has helped create hits for many notable artists including John Legend, Rick Ross and fellow Wondaland label mates Janelle Monae and Jidenna. However, his musical genius and path to the entertainment industry began in one of the most unlikely places—a hospital.

Hematopoietic stem cell transplantation from HLA-matched sibling donors results in disease free survival of >90% in patients with sickle cell disease (SCD) but only about 18% have suitable donors. Unrelated cord blood transplantation (UCBT) is one way to expand donor options for patients with severe SCD but historically has been associated with high graft rejection rates (50-62%). We hypothesized that the addition of thiotepa to a previously tested reduced intensity conditioning (RIC) regimen would support engraftment after UCBT in SCD patients. Nine children (3-10 years) with cerebrovascular complications of SCD underwent 5-6/6 HLA-matched (A, B and DRB1 loci) UCBT after conditioning with hydroxyurea, alemtuzumab, fludarabine, thiotepa and melphalan. A calcineurin inhibitor and mycophenolate mofetil were used for graft-versus-host-disease (GVHD) prophylaxis. With median follow up of 2.1 (range 1-4.2) years, seven patients had sustained donor cell engraftment and are free of SCD, two had autologous recovery. Acute GVHD (grade 2-4), mild, and moderate chronic GVHD developed in three, two, and one patient respectively. Of five patients >2 years post-UCBT, four have discontinued systemic immunosuppression. Seven patients had viral infections (CMV, EBV, RSV or Adenovirus) and recovered. The 1-year overall and disease free survival rates were 100% and 78% respectively. Thus, this RIC regimen was able to achieve donor engraftment in the majority. Future efforts will focus on further reducing acute GVHD and viral infection rates.

You need to rank the scores for maths and English separately. The score with the highest value should be labelled "1" and the lowest score should be labelled "10" (if your data set has more than 10 cases then the lowest score will be how many cases you have). Look carefully at the two individuals that scored 61 in the English exam (highlighted in bold). Notice their joint rank of 6.5. This is because when you have two identical values in the data (called a "tie"), you need to take the average of the ranks that they would have otherwise occupied. We do this because, in this example, we have no way of knowing which score should be put in rank 6 and which score should be ranked 7. Therefore, you will notice that the ranks of 6 and 7 do not exist for English. These two ranks have been averaged ((6 + 7)/2 = 6.5) and assigned to each of these "tied" scores.

Individual differences and cognitive models of the mind: using the differentiation hypothesis to distinguish general and specific cognitive processes

Spearman's Rank-Order Correlation - A guide to when to …

This chapter uses a hypothesis from research on individual differences in cognitive ability – the differentiation hypothesis – to show that individual differences can be informative for cognitive models of the mind. The differentiation hypothesis comes in two forms. The developmental differentiation hypothesis argues that as children develop, their abilities become more differentiated, and that, as adults age, their abilities become de-differentiated. The individual differences differentiation hypothesis states that abilities are more differentiated at higher IQ. Differentiation is usually inferred from either a smaller -factor or a lower average inter-test correlation. Simulations of alternative models that specify different functional relationships between processes underlying the g-factor and specific abilities are presented. A common but simple interpretation of the apparent de-differentiation of abilities with advancing age, and increasing differentiation with development in children, is that a single common factor underlies both and developmental change. The simulations reveal that this simple interpretation is unwarranted.

Spearman's law of diminishing returns. A meta-analysis

What constitutes intelligence and how it develops continue to be sources of much debate and disagreement among psychologists. We are now confronted with a range of theories about intellectual development, each with its own appeal, and each focusing on different aspects of what may constitute intelligence. Nevertheless, current theories do manifest some common ground (e.g., a concern with changes in information processing abilities in Sternberg’s theory and in the approach adopted by neo-Piagetians). It remains to be seen whether anything approaching a unified theory about the development of intelligence can ever be achieved. Future research needs to seek more measures of what might constitute precursors to childhood intelligence during infancy that arise from a well-articulated theory. In this respect, a concern for cortical brain development as is evident in the emerging field of developmental cognitive neuroscience has potentially much to offer. In addition, we need to know more about the mechanisms of developmental transitions in intelligence, in which this emerging field may play a vital role.
