Death Feigning

Thanatosis (pretending to be dead), sometimes called letisimulation, is widely used as an anti-predator strategy by snakes. Herein we report six cases of death-feigning in six species of Panamanian snakes (Dark-headed Red Falseboa, Pseudoboa neuwiedii; Double-banded False Coralsnake, Erythrolamprus bizona; Forest Flamesnake, Oxyrhopus petolarius; Rufous-headed Snake, Amastridium veliferum; Colombian Long-tailed Snake, Enuliophis sclateri; and Pacific Banded Coffee Snake, Ninia maculata). We also present a literature review of thanatosis in American snakes and discuss the terminology associated with this behavior.

And Training

Computerized auditory training (CAT) is a convenient, low-cost approach to improving communication of individuals with hearing loss or other communicative disorders. A number of CAT programs are being marketed to patients and audiologists. The present literature review is an examination of evidence for the effectiveness of CAT in improving speech perception in adults with hearing impairments. Six current CAT programs, used in 9 published studies, were reviewed. In all 9 studies, some benefit of CAT for speech perception was demonstrated. Although these results are encouraging, the overall quality of available evidence remains low, and many programs currently on the market have not yet been evaluated. Thus, caution is needed when selecting CAT programs for specific patients. It is hoped that future researchers will (a) examine a greater number of CAT programs using more rigorous experimental designs, (b) determine which program features and training regimens are most effective, and (c) indicate which patients may benefit from CAT the most.
