Averaged event-related cortical potentials (ERPs) were obtained from an array of scalp electrodes overlying the left hemicranium in response to regularly presented visual or auditory stimuli (non-signals)and to infrequent random replacements by different stimuli (signals) in the same modality. A motor response was required to the signals. Non-signal ERPs… (More)
Social networks and the need to communicate are universal human conditions. A general assumption is that communication technologies help to increase and strengthen social ties. The Internet provides many social networking opportunities. But how do social networking sites affect individual relationships? Do people use social networking sites to expand their… (More)
We used a combined behavioral and electrophysiological technique to test the hypothesis that storage of information is impaired in childhood autism. Endogenous event-related potentials associated with the random deletion of stimuli within a regular train of auditory or visual stimuli were examined in three autistic and three normal children. We found that… (More)
In this paper we examined a set of seven heuristic evaluations with specific attention to issue identification overlap among professional heuristic evaluation reviewers. We also evaluated the effectiveness of conducting a group review.
