Rey complex figure: memory error patterns and functional abilities.

The functional abilities of brain injured persons to live independently, were assessed using the Rancho Los Amigos Scale ratings of functional levels which were compared with memory error patterns on the Rey Complex Figure (Rey 1941) and the Recognition Trial developed by Meyers & Meyers (1995) Memory error patterns were described by Sohlberg & Mateer (1989), the least impaired memory error pattern was Retrieval, while Storage, Encoding and Attention patterns indicated greater defect Spearman rank order correlation revealed the strong association (r(S) = 86) of memory error pattern with Rancho Scale functional ratings In independent subjects 96 % achieved a Retrieval memory error pattern whereas 93% of subjects whose memory error pattern was poorer than a Retrieval pattern were unable to function independently Results indicate that patients obtaining a Retrieval (or better) memory error pattern may be expected to possess adequate cognitive resources for independent functioning.

Presidents Test performance in varieties of diffuse and unilateral cerebral disease.

Two studies addressed issues concerning the validity of the Presidents Test. The results of Study 1 substantiated that generalized impairment for recent presidents occurs frequently in the context of multifocal and diffuse cerebral disease. Performances of normal elderly (n = 31) on all four Presidents subtests were superior to those of patients with confusional states (n = 7), uncomplicated dementia (n = 24), and dementia with confusion (n = 20). Overall, 88% of the combined sample was correctly classified (control v. diffuse cerebral disease). In Study 2, generalized memory impairment for recent presidents was found to be rare among samples of patients with unilateral right- and left-hemisphere lesions (n = 40 each). A selective impairment in temporal sequencing was preferentially associated with right-hemisphere disease, whereas verbal deficit patterns were more common in patients with left-sided lesions. These findings further document the validity of the Presidents Test as an efficient, objective method for assessing recent memory impairment due to widespread cerebral disease and suggest that qualitative analysis of performance patterns may be useful for detecting certain nonmnemonic cognitive defects in patients with focal brain disease.

Tinker toy test performance and vocational outcome in patients with closed-head injuries.

Fifty patients who had suffered closed-head injury with no resultant physical disabilities and 25 normal controls were administered a modified version of Lezak's Tinker Toy Test. All head-injured patients were examined at least 24 months following medical clearance to return to work. Twenty-five of the head injured had been unable to return to work or sustain normal competitive employment as a result of their head injuries. The remaining 25 had returned to their previous jobs successfully or had been employed for at least 6 months prior to assessment. Whereas all but one of the head injured who returned to work scored normally on the Tinker Toy Test, nearly half of the nonreturnees performed below the level of the worst control.

Ideogram reading in normal and dyslexic children.

This study was concerned with the ideogram reading performances of groups of reading disabled and normal children. While adults with acquired alexia have associated defects in ideogram reading, all of the dyslexic children performed at normal adult levels. It was found that ideogram reading in control children is rather slow to develop, with only 7 and 8 year old subjects performing like normal adults; this is in contrast to other reading-related cognitive tasks in which normal performance develops earlier.
