  • The aim of the paper was to study the intellectual profile of 94 gifted elders aged 60–90 years old with an IQ equal to or higher than 130 on at least one of the four primary indexes of the Wechsler Adult Intelligence Scale – Fourth Edition. Their performances in the 15 subtests, in the Full Scale Intelligence Quotient, in the primary, supplementary and Cattell-Horn-Carroll theory Indexes, were analyzed. This group exhibited a significantly higher level of performance in all subtests and indexes than the control group matched for gender, age, and education. The differences between the two groups appear higher for the Matrix reasoning and Visual puzzle subtests. Additionally, in the gifted group the strengths seem to be represented more by Processing Speed and Perceptual Reasoning Indexes, in the control group are Comprehension Verbal and Working Memory Indexes. Moreover, gifted elders showed lower discrepancies across intellectual domains. These data provide evidence that, as the difference between the gifted group and the control group revealed in the present study is more due to processing speed, this dimension, which normaly is most affected by aging, on the contrary, is maintained/increased as a strength in the gifted elderly group.

  • The current study aims first, to compare mean performance data of intellectually gifted individuals on the WAIS-IV with a matched comparison group; second, to revalidate the CHC five-factor structure of the WAIS-IV within this special group. 157 Italian Mensa members (125 males) were administered the full battery (i.e., both 10 standard and 5 supplementary subtests). The individuals were aged 18-60 years and had a mean age of 33.97 years (SD = 10.22). Results showed that i) Mensa members’ IQ mean was approximately in the gifted range; moreover, they had the highest performances in visual perceptual reasoning, while they were relatively weak on processing speed; ii) CHC factor structure suggested by Pezzuti et al. (2017) was confirmed; Perceptual Reasoning Index grouped two different broad abilities, i.e. Fluid Reasoning (with Arithmetic loaded on it stronger than on Short Term Memory) and Visual Processing.

Per questo, è stata somministrata l’intera batteria (cioè, i 10 subtest standard e i 5 supplementari) ad un campione di 157 membri del Mensa Italia (125 maschi). Entrambi i gruppi avevano un’età compresa tra 18-60 anni e avevano un’età media di 33.97 anni (DS = 10.22). I risultati hanno mostrato che: i) il QI medio dei membri del Mensa si collocava a ridosso del range dei soggetti plusdotati; inoltre, i soggetti plusdotati avevano prestazioni migliori nei compiti di ragionamento visuopercettivo e una debolezza relativa nella velocità di elaborazione; ii) la struttura fattoriale CHC suggerita da Pezzuti et al. (2018) è stata confermata. L’Indice di Ragionamento visuo-percettivo raggruppava due abilità ampie distinte: Ragionamento Fluido (con Ragionamento aritmetico che mostrava una maggiore saturazione su di esso rispetto all’abilità di Memoria a breve termine) ed Elaborazione Visiva.
