چکیده

From Jensen's two-level theory of mental abilities (Level I: rote learning and memory; Level II: complex cognitive processing) it was predicted that forward digit span (F1JS) should correlate less with IQ than backward digit span (BDS), and age and race should interact with FDS-BDS, with the FDS-BDS difference decreasing as a junction of age and a greater white-black difference in BDS than in FDS. The predictions were substantiated at a high level of significance in large representative samples of white and black children of ages 5 to 12 years, who were given the Wechsler Intelligence Scale for Children (Revised). Socioeconomic differences were found to account for less of the predicted effects than race.

Forward and backward digit span interaction with race and IQ: predictions from Jensen's theory.

From Jensen's two-level theory of mental abilities (Level I: rote learning and memory, involving little or no transformation of the input; Level II: complex cognitive processing involving transformation and mental manipulation of input) it was predicted that forward digit span (FDS) should correlate less with IQ than backward digit span (BDS), and age and race should interact with FDS-BDS, with...

The effects of dopamine on digit span in Parkinson’s disease

BACKGROUND Parkinson's disease patients are at an elevated risk of developing cognitive impairment. Although cognitive impairment is one of the strongest predictors of quality of life, dopaminergic anti-parkinsonian medications are designed to target motor symptoms. However, there is substantial evidence that dopamine also impacts cognition, in particular working memory. It is therefore critica...

Enhancing Working Memory Capacity in Persian Cochlear Implanted Children: A Clinical Trial Study

Introduction: Sensory deprivations such as hearing impairment that affect sensory input have a secondary impact on cognitive functions such as working memory (WM). WM capacity is an important cognitive component that processes language-related activities. Moreover, several studies have shown a deficit in WM in children with a cochlear implant (CI). We aimed to assess the performance of children...

Running Head: FORWARD & BACKWARD DIGIT SPAN IN SLD The Version of Scholarly Record of this Article is published in JOURNAL OF CLINICAL AND EXPERIMENTAL NEUROPSYCHOLOGY

This study examined performance in the forward and backward digit span task of the Wechsler Intelligence Scale for Children–Fourth Edition (WISC-IV) in a large group of children with specific learning disorder (SLD) as compared with a group of typically developing children matched for age and sex. Our results further support the hypothesis that the intellectual difficulties of children with SLD...

Verbal working memory impairment in schizophrenia patients and their first-degree relatives: evidence from the digit span task.

OBJECTIVE The evidence for verbal working memory deficits in schizophrenia has been inconsistent. Few studies have evaluated verbal working memory in the first-degree relatives of schizophrenia patients, who likely share the genetic diathesis for schizophrenia but not the potential confounds associated with chronic mental illness. METHOD The Wechsler Digit Span Task was used to investigate ve...
