The fate of memory: comment on McCloskey and Zaragoza.

McCloskey and Zaragoza (1985) argue that misleading postevent suggestions do not affect the availability of originally encoded information. Their hypothesis stems from empirical work using a modified paradigm in which no effect of postevent information is observed. Although their "no impairment" hypothesis is plausible, careful consideration of the predictions of their experimental test suggests that it may be insufficiently sensitive to reveal the impact of postevent information. A small effect of postevent information can be observed when their paradigm is repeated with a more sensitive recognition test. McCloskey and Zaragoza's no impairment hypothesis is also difficult to reconcile with numerous reports of "blend" memories that reflect a compromise between the original and postevent information.

Performance of epileptic patients in continuous reaction-time situations.

Through the use of a 4-choice continuous reaction-time paradigm, the hypothesis that epiliptic patients have frequent lapses of attention was tested. Control subjects were nonepileptic mentally retarded subjects matched for IQ and CA. Experimental variables were: paced and self-paced work, massed and spaced work periods, and short or long stimulus exposition. The epileptic patients performed well as compared to the control group or to nonretarded persons with respect to reaction time, accuracy, and the occurrence of mental blocks. No abnormal disturbance of attention was clearly detected. This conclusion leads to the possibility that even for patients with severe epilepsy, some tasks can be defined that they can perform successfully.
