in recent years, biotechnology has provided the possibility of creating genetically modified (gm) organisms by transferring genes from sources such as viruses, bacteria, animals, and plants into usually unrelated species. this ability to overcome insurmountable physiological barriers by exchanging genetic materials among all living organisms is a double-edged sword. on the one hand, it allows t...

Patients with central vision loss must rely on their peripheral vision for reading. Unfortunately, limitations of peripheral vision, such as crowding, pose significant challenges to letter recognition. As a result, there is a need for developing effective training methods for improving crowded letter recognition in the periphery. Several studies have shown that extensive practice with letter st...

Effects of stimulus duration and inter-letter spacing were studied in a letter-in-string identification paradigm. Participants were shown strings of 5 random consonants (e.g., PGKDM) centered on fixation and were asked to identify the letter that had appeared at a post-cued location. Stimulus duration was manipulated in Experiment 1 (13 ms-91 ms), and inter-letter spacing manipulated in Experim...

Pure alexia is characterised by a very time-consuming letter-by-letter reading strategy due to an impaired identification or integration of single letters. So far, therapy interventions have addressed impaired letter identification using specific single-letter training approaches. In the present study, we report patient KA with pure alexia and letter-by-letter reading. Contrary to common approa...
