The assessment of reading readiness using multidimensionally scored time-compressed speech.

Normal-hearing children (39 M, 36 F) from a monolingual environment, aged 5 yrs 10 mo to 7 yrs 2 mo, of average or better intelligence, were selected as being at high, average, or low risk of reading readiness according to scores on the Lindamood Auditory Conceptualization (LAC) test. Ss were also given the Stephens Oral Language Screening Test (SOLST), emphasizing syntactical development. Ss were then tested for verbal respeating of taped 5-word sentences and 5-word 1st-order sentential approximations at 32 db SL re SRT. Stimuli were presented at 0, 40, or 60% time compression (TC). Responses were scored right/wrong and also by Porch's multidimensional system involving repeats and cues. For both systems significant effects were obtained between a number of TC conditions vs both the LAC and SOLST. The LAC appeared to emphasize phonetic units, the SOLST linguistic units in real sentences. The TC condition appeared to emphasize linguistic units at both word and sentence levels, less so with increasing TC. Results supported the usefulness of the TC stimuli in assessing reading readiness and it was suggested that the various stimuli assess different aspects of auditory processing.

Children's performance on multidimensionally scored time-compressed sentential stimuli.

Normative data were obtained for 96 children with normal auditory and language abilities in grades 2, 4, and 6 when presented monaurally with time-compressed (TC) sentences and 1st- and 2nd-order sentential approximations at 32 db re SRT. Oral responses were taped and multidimensionally scored in order to sensitize the test. Consistent with previous reports of normative data at other age levels, performance became poorer for 0 to either 40 or 60% TC (there was a negligible difference between the latter), was better for normal sentences than for sentential approximations, and improved slightly in the higher grades.

Veterans Administration cooperative study on aphasia: a comparison of individual and group treatment.

Five Veterans Administration Medical Centers participated in an investigation designed to compare individual with group treatment for aphasic patients who had suffered a left hemisphere cerebral vascular accident. Patients who met selection criteria were assigned randomly to either traditional, individual, stimulus-response type treatment of specific language deficits or group therapy designed to improve communication through group interaction and discussion with no direct treatment of specific language deficits. All patients received eight hours of therapy each week beginning at four weeks postonset and continuing until 48 weeks postonset or until they dropped out of the study. A battery of language measures and a clinical neurologic evaluation were administered at intake and every 11 weeks a patient was in the study. Results show both individually and group-treated patients made significant improvement in language abilities. Individual treatment resulted in significantly better overall performance on the Porch Index of Communicative Ability; however, no significant differences were observed between groups on the other language measures. If the traditional belief is correct that significant spontaneous recovery is complete by three to six months postonset, significant improvement in both groups beyond 26 weeks postonset indicates both individual and group treatment are efficacious methods for managing aphasic patients.

Statistical prediction of change in aphasia.

We reviewed speech, language, and biographical data on 144 asphasic patients who had suffered left hemisphere cerebral vascular accidents. Using a step-wise multiple regression procedure, we attempted to predict change in severity of aphasia at three, six, and 12 months postonset based on performance at one, three, and six months postonset. Our results suggest statistical prediction of change is feasible. Multiple correlation coefficients ranged from 0.74 to 0.94.

Aphasia and the expert medical witness.

Psychiatrists have recently been criticized from within and outside the profession for rendering professional opinion in instances where their qualifications are inadequate. In forensic psychiatry, the problem of predicting dangerousness is a notable example. The forensic psychiatrist may also be called to testify as to the present or future competency of the aphasic patient. It therefore behooves the medical expert to be fully aware of the new developments within the field of aphasiology so that in cases involving aphasia the best combined expert testimony can be rendered the court.
