Current research in the fields of the Sciences of Aging draws attention to the need for studies on the group of elderly people with 80 years and over, called very elderly or "oldest old". The need for studies on this population is justified by the high prevalence of morbidities and disabilities that affect these elderly people, compromising their autonomy and functional capacity, generating a greater risk for falls and institutionalization. Beyond the chronological criteria adopted in the literature, however, it is known that the experience of aging and the awareness of the passing time are also conditioned by a subjective factor, rendering criteria based on exteriority, such as numbered age, insufficient to circumscribe the complex experience of aging. Aiming at understanding the particularities of this population segment, the objective of this research is to investigate the perceptions of the very elderly about the passage of time and the pathways of its psychic inscription. A field research of an exploratory nature was carried out, involving quantitative and qualitative methodologies. The study included 30 elderly people aged 80 years and over, divided into two groups: elderly people living in the community and elderly people living in a geriatric home. The following instruments were used for data collection: the Mini Mental State Examination (MMSE), a Socioeconomic and Health Characterization Questionnaire, a Semistructured Interview, eight boards of the Senior Apperception Technique (SAT) and the abbreviated version of the Geriatric Depression Scale (GDS-15). The comparison of the results of the SAT showed that the elderly who reside in the geriatric home demonstrated more positive perceptions about old age and the relationships established at this stage of life, deconstructing some of the stigmas related to geriatric institutions. There was also a higher positive score for depression in GDS-15 and lower scores in the group of elderly people residing in the community. As the main results of the qualitative analysis of the interview and SAT indicate, the time of old age is the product of the encounter between the time of Kairos and the time of Cronos, the first one being based on a subjective temporal meaning and the second on a conception of objective and sequential time. This encounter occurs in different real experiences with the externality, such as loss of bonds and bodily alterations, that are configured as ways of psychic inscriptions of the objective temporality, entailing awareness about the existence of a time external to the Ego which places the subject in the present moment of old age. Therefore, a greater consciousness of transience is the denominator that confers specificity to the experience of the oldest old with the passage of time. The adoption of epistemologically distinct instruments, such as scales, projective technique and interview, proved itself to be a valid methodological standpoint for the investigation of the phenomena of old age. This research is considered to have fulfilled its o...
