appllonts MaY hav re sulted in a mn~er of erro, Probably a

number of un did not ewn oplete tbh oaurst Ho r. one aspect

in this stdw is that, as mntianed abonw, the mte of 3aamning

was geat-er than could have been Indicated by the test soores obtained

frtm these Bn.

'o~f ae two points apparent frca tih abovw evidence. Ow is

that ind dals who awe been diaosed as mentally flboti w Ahen

ohildm en the basis of test socaes haw Ind iated tkat they can

Iam a 'esbrM' ate than their test scamw oould Law sugsted.

Malidng a sastisfatotr mocal and eoonaoed adjustmnt in the oaaam ity

requires the ability to solw problimn on a rather ocmplex lewl.

Apparmnty these inzdivdals mwore able to solve problem in e4ny
sit-ation other than those et in itell gme test a slbitSie.

o wsond point suspasted is the clear l bqa of amy

eamnuiains relating to mntsl retarzdation which have been based on

duta obtakimd solely fru intellione test msores. M statement r

ds above that such tests my measiue a narzowly listed rang of

problem solving sitatin. The studies of vis and Havlgurst (1948)

indicate that intelligenme tests eaegle oly a limited number of

Intellseotal prooesses and, of those processes sampled, no are those

which would be nsoaessry fr school perfoTa e. Alo, the wsel of
Davis and lhvighust (1948) indicates tbat oonwnstknaml intellience

tests acnsist of item related to a dddle slaas cunlt'e only and are

S2h third hypothesis stated that there would be a greater

suppression of perfonrSnce efficiency with oneam interpolated problem

(fourth problem reversed) then with fur Interpolated problem

(frset problem reversed) for the brain dgd group It was

stated that the brain dmresvd group, because of poor lamudiate

wm=7o poor attention spen, distractibillty, ete., would mmniftst

less interf"rene, after four Interpolated problem because they would

be more likely to fort the block which had been originally

reinforced. It was further ~lt. that there would be are inter-

fernce in perfbrnaoe after ow interpolated problem due to the

fact that these subjects would be less likely to shift from respond-

ing to oe block as positive to responding to the previously negfr

tive block as now positive. Such a shift after only one interpolated

problem should be difficult because of the trait of rigidity

hawreateristio of the brain dindividual. Table 5 presents

the median eirrt obtained by eaoh p at eaoh lnevl of training

for both the orignal and reversed problem when the frtWi

problem are reversed.
