Start date: 1994
History:
The BIAL Foundation was created in 1994 by Laboratórios BIAL in conjunction with the Council of Rectors of Portuguese Universities. BIAL’s Foundation mission is to foster the scientific study of Man from both the physical and spiritual perspectives.
Along the years the BIAL Foundation has developed an important relationship with the scientific community, first in Portugal and after worldwide. Today it is an institution of reference which aims to stimulate new researches that may help people, promote more health and contribute to new milestones to gain access to knowledge.
Among its activities the BIAL Foundation manages the BIAL Award, created in 1984, one of the most important awards in the Health field in Europe. The BIAL Award rewards both the basic and the clinical research distinguishing works of major impact in medical research.
The BIAL Foundation also assigns Scientific Research Scholarships for the study of neurophysiological and mental health in people, arousing the interest of researchers in the areas of Psychophysiology and Parapsychology.
To date the BIAL Foundation has supported 461 projects, more than 1000 researchers, with research groups in twenty-seven countries, resulting, until April 2013, in about 600 full papers, out of which 172 published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Since 1996 the BIAL Foundation organizes the Symposia entitled "Behind and Beyond the Brain", a Forum that gathers well renowned neurosciences speakers and the BIAL Foundation Fellows which are spread around the world.
Classified as an institution of public utility, the BIAL Foundation includes among its patrons the Portuguese President, the Portuguese Universities Rectors' Council and the Portuguese Medical Association.

Abstract/Results: RESULTS:
Studies on temporal perception lack a validated method and a consensual “gold-standard” to measure time perception. Evidence suggests deterioration of timing with aging. This study aimed to develop and validate a neuropsychological tool to measure time perception and to study temporal perception along aging.
Eighty-six healthy subjects, aged 15-90 years-old, were prospectively asked to verbally estimate and produce empty intervals signaled by auditory beeps, of 7, 32 and 58 seconds duration. Two tests were used as “gold standards”: estimating the duration to draw a clock (“clock time”) and estimation of the duration of neuropsychological evaluation (“global time”). Results showed a correlation between estimation and production (p<. 01), and a correlation between estimation or production and “global time” (p<. 01). A correlation between either estimation or production and age (p<. 01), indicating faster internal clocks with aging. Comparison between three age groups (15-40 yrs-old; 41-64 yrs-old; 65-90 yrs-old), showed a trend toward overestimation and underproduction with older age, reaching significance between the extreme age groups (p< .05).
The proposed test seems a good tool to measure subjective duration and the results showed an acceleration of internal clock with aging.

Abstract/Results: ABSTRACT:
Studies concerning time perception lack a validated assessment tool and a consensual “gold-standard” measure. Moreover, the present evidence suggests modification of timing with aging. This study aimed to develop and validate a neuropsychological tool to measure time perception and to study temporal perception with aging. Eighty-six healthy participants, aged 15–90 years old, were asked to verbally estimate and produce empty intervals signaled by auditory beeps, of 7-, 32-, and 58-s duration. Two tests were used as “gold-standards”: estimation of the duration of time necessary to draw a clock (“clock time”) and estimation of the duration of neuropsychological evaluation (“global time”). Results showed a correlation between estimation and production (p < .01) and a correlation between estimation or production and “global time” (p < .01). The correlation between either estimation or production and age (p < .01), suggested a faster “internal-clock” in the older participants. However, this finding lost significance when controlled for literacy. The results suggest that these tests are potentially a useful tool to measure subjective perception of time. They also corroborate the hypothesis of a change in subjective time perception with aging. It was not possible to conclude if this effect was a specific result of aging or biased by the interference of literacy.

Title: BIAL Grants
Start date: 1994
History:
In 1994 the BIAL Foundation launched a programme of science research grants with the aim of encouraging the research into Man’s physical and mental processes, namely in fields still largely unexplored but which warrant further scientific analysis, as Psychophysiology and Parapsychology.
Since its launch, applications to the BIAL grants have been increasing. Up to now 461 projects have been supported, involving more than 1000 researchers from 27 countries.
The approved applications have benefited from grants in amounts comprised between €5,000 and €50, 000. The amount to be granted is fixed by the Scientific board according to the needs of each project.
The supported projects have originated, until April 2013, in about 600 full papers, 172 out of which were published in indexed international journals with an average impact factor of 3.6 and a substantial number of citations (1665).
Among the BIAL Foundation fellows is worth highlighting the presence of scientists from prestigious universities from the United States, United Kingdom, Australia, Russia, Germany, Japan, France, Canada, and many others.
The BIAL grants are promoted biannually.

Abstract/Results: ABSTRACT:
Studies concerning time perception lack a validated assessment tool and a consensual “gold-standard” measure. Moreover, the present evidence suggests modification of timing with aging. This study aimed to develop and validate a neuropsychological tool to measure time perception and to study temporal perception with aging. Eighty-six healthy subjects, aged 15-90 years-old, were asked to verbally estimate and produce empty intervals signaled by auditory beeps, of 7, 32 and 58 seconds duration. Two tests were used as “gold-standards”: estimating the duration of time necessary to draw a clock (“clock time”) and estimation of the duration of neuropsychological evaluation (“global time”). Results showed a correlation between estimation and production (p<0.01) and a correlation between estimation or production and “global time” (p<0.01). The
correlation between either estimation or production and age (p<0.01), indicated a faster “internal-clock” with aging. A comparison between three age groups (15-40 yrs-old; 41-64 yrs-old; 65-90 yrs-old) showed a trend toward time overestimation and underproduction with older age, reaching significance between the extreme age groups (p< 0.05). The results suggest that these tests are potentially a useful tool to measure the subjective perception of time and corroborate the hypothesis of an acceleration of “internal-clock” with aging. In other study, ten patients with Parkinson`s disease and “wearing-off” and no dementia performed
the above tasks for time estimation and production; patients were evaluated in the “ON” and “OFF” stage. We found no difference between patients and controls. In a sub-group analysis, two different behaviors emerged: a subgroup of patients had a faster “internal-clock” during “ON” stage while other had a faster “internal-clock” off levodopa, but this difference did not reach statistical significance. Further studies are needed to investigate the role of dopamine in time perception.
