The first factor explained the 35.2% of the variance and included naming (factor loading; r = 0.79), verbal repetition (factor loading; r = 0.68), immediate memory (factor loading; r = 0.66) and writing (factor loading; r = 0.65).
A closer examination of the Freedom from Distractibility and Verbal Comprehension factors can provide some insight into the functional significance between PCB exposure and the associated IQ deficits.
This factor included constructional praxis (factor loading; r = 0.71), reading a sentence (factor loading; r = 0.53), attention/concentration (factor loading; r = 0.51) and verbal comprehension (factor loading; r = 0.38).
For the gifted population, the skills required in the Verbal Comprehension factor are traditionally the strongest indicators of giftedness and this was found to be true with the standardization sample.
A factorial design was used with factors verbal class (semantic vs. overlearned fluency) and switching between categories (no vs. yes).
Cognitive factors, verbal IQ, reading and mathematical achievement are also examined.
In addition, performance measures on the non-symbolic number comparison task ('Speed' and 'Accuracy') and performance on number/counting knowledge tasks ('Counting, number knowledge and verbal fluency') form factors which are independent of each other.
Differentiated in a total score (10 items × 1 4 points (range 10 40 points)) and subscores for the factors Verbal Perseveration and Imaginal Prefiguration (5 items × 1 4 points (range 5 20 points)).
The neuropsychological test scores were converted to Z-scores (standard equivalents) and single test values covering the same neuropsychological faculty were averaged to define the following factors: verbal learning/memory, visuo-spatial learning/memory, working memory/concentration and frontal lobe functioning.
When interpreting others' body language, it's important wherever possible to take into account their personality, social factors, verbal behavior, and the setting.
