Abstract

Bu çalışmada, A-B A-C paradigması kullanılarak

DEHB'li çocukların nesne yerlerini

hatırlamada bozucu etki (ilklik etkisi) bakımından

DEHB tanısı almayan çocuklardan

farklılaşıp farklılaşmadığının araştırılması

amaçlanmıştır. Mekânsal bellek testi olarak

kullanılan A-B A-C yer öğrenme görevinde,

katılımcılardan ardışık iki sunum halinde verilen

7 (A) yerin her biriyle eşleşmiş ikişer nesne

(B ve C nesneleri) olmak üzere, toplamda

14 nesnenin yerini hatırlamaları istenmiştir.

Analiz sonuçları, DEHB grubunun kontrol

grubuna benzer bir şekilde B nesnelerini,

C nesnelerine göre daha fazla hatırladığını

(ilklik etkisi) göstermiştir. Doğru hatırlanan

B nesne sayısı bakımından gruplar arasında

anlamlı fark bulunmasa da, doğru hatırlanan

C nesne sayısı bakımından gruplar arasındaki

farkın anlamlılık düzeyine yaklaştığı

gözlenmiştir. Nesne yerlerini hatırlarken her

iki grupta da ilklik etkisi görülmesi, Aracı

Süreçler Kuramı'na göre B nesnelerini aracı

olarak kullanmayı gerektiren bir öğrenme

stratejisinin benimsendiğini göstermektedir.

Bulgular, DEHB'li çocukların mekânsal bellek

becerilerinin uygun öğrenme stratejisi desteği

ile geliştirilebileceğini düşündürmektedir.

An Investigation into Spatial Memory of ADHD Children by Using an A-B A-C Paradigm

Abstract

The present study aimed to examine priori-

ty effect on object-location memory in children

with ADHD, in comparison to children without

ADHD, by using an A-B A-C paradigm. An

A-B A-C paired position learning task was

administered to both ADHD and non-ADHD

children. The children learned positions of

14 different objects (7 B- and 7 C-objects)

around 7 referent objects (A-objects) in two

successive presentations (first Bs followed by

Cs) and then they were given A object positions

and asked to recall positions of B and C. The

results revealed a significant priority effect on

object location memory of the ADHD group,

similar to that of the control group. B positions

were recalled better than C positions by both

groups. The number of B objects correctly

recalled did not differ significantly between the

two groups. On the other hand, the difference

in recall of C objects approached, but did

not reach, the significance level. According

to the mediational theory, priority effect is

a result of a learning strategy that involves

retainment of B during A-C learning, therefore

the effect observed in performances of the

ADHD and non-ADHD children indicated

that both groups used the strategy. This sug¬

gests that spatial memory abilities of children

with ADHD may be improved with the use of

appropriate learning strategies.
