- PósterEmotional episodic memory formation during Covid-19 quarentine: preliminary results(2020) León, Candela S.; Bonilla, Matías; Urreta Benítez, Facundo A.; Forcato, Cecilia"Episodic memory is the ability to recover past experiences and projects ourselves into the future. It is related to contextual information (both spatially and temporally). This type of memory is highly sensitive to aging, the passage of time, forgetfulness, interference and confusion. Furthermore, episodic memory processes are modulated by both anxiety and depression. People's mental health has deteriorated due to the Covid-19 pandemic, showing higher levels in both values. There is a general consensus that pleasant or aversive events are better remembered than neutral events. Regarding false memories, there is no such consensus. Some authors found that emotional content generates more false memories, however, it was also found that negative content reduces false memories. In this study we evaluated the effects of emotional variables, such as anxiety and depression, on memory encoding and consolidation of true and false details of aversive and neutral stories."
- PósterFormación de memorias episódicas aversivas durante la pandemia por COVID-19(2021) León, Candela S.; Bonilla, Matías; Urreta Benítez, Facundo A.; Brusco, Luis Ignacio; Wang, Jingyi; Forcato, Cecilia"La memoria episódica es la capacidad de recordar qué, dónde y cuándo ocurrió un evento. Además, existe consenso en cuanto a que los eventos agradables o aversivos se recuerdan mejor que los eventos neutrales y que los procesos de memoria episódica están modulados por la ansiedad y la depresión. La salud mental de las personas se ha deteriorado debido a la pandemia de COVID-19, mostrando un aumento de los síntomas de ansiedad y depresión. Aquí, planteamos la hipótesis de que el aumento de síntomas negativos modifica la capacidad de codificar y consolidar recuerdos. Para estudiar esto, evaluamos los efectos del contexto emocional en la codificación y consolidación de recuerdos episódicos neutrales y aversivos."
- Artículo de Publicación PeriódicaIdentification performance during quarantine by COVID-19 pandemic: Influence of emotional variables and sleep quality(2021) Urreta Benítez, Facundo A.; León, Candela S.; Bonilla, Matías; Flores-Kanter, Pablo Ezequiel; Forcato, Cecilia"The COVID-19 pandemic has caused major disruptions in people’s lives around the globe. Sleep habits and emotional balance have been disturbed in a way that could be comparable to the havoc caused by a deep personal crisis or a traumatic experience. This unfortunate situation provides a unique context in which to study the impact of these imbalances on cognitive processes. In particular, the field of eyewitness science could benefit from these conditions, since they are also often present in crime victims, but can only be generated in the laboratory up to a certain ethical and practical limit. For several decades, eyewitness studies have tried to discover what variables affect people’s ability to properly recognize faces. However, the disparity of experimental designs and the limitations of laboratory work could be contributing to the lack of consensus around several factors, such as sleep, anxiety, and depression. Therefore, the possibility of observing the influence of these agents in natural contexts could shed light on this discussion. Here, we perform simple and repeated lineups with witnesses of mock-crime, considering the conditions related to the COVID-19 pandemic, which to some extent allow emulating the deterioration in general well-being that often afflicts crime victims. For this, 72 participants completed symptomatology scales, and watched a video portraying a staged violent episode. Subsequently, they gave testimony and participated in two lineups, in which we manipulated the presence/absence of the perpetrator, to recreate critical scenarios for the appearance of false recognitions. We found an increase in recognition errors in those individuals who did not have access to the perpetrator during the Initial lineup. Additionally, the conditions of the pandemic appear to have adversely affected the ability to witness and accurately perform lineups. These results reaffirm the need to move toward the standardization of research practices and methods for assessing testimonial evidence, especially in relation to the results of the lineups. Considering the degree of fallibility of these processes can lead to a reduction of wrongful convictions."
- PósterImpairment of aversive episodic memories during covid-19 pandemic: The impact of emotional context on memory processes(2021) León, Candela S.; Bonilla, Matías; Urreta Benítez, Facundo A.; Brusco, Luis Ignacio; Wang, Jingyi; Forcato, Cecilia"Episodic memory is the ability to recall about what, where and when the event happened. Furthermore, there is a consensus that pleasant or aversive events are better remembered than neutral events and that episodic memory processes are modulated by anxiety and depression. People's mental health has deteriorated due to the COVID-19 pandemic, showing a growth in anxiety and depressive symptoms. Here, we hypothesize that the increase in negative symptoms modifies the ability to encode and consolidate memories. To study this, we evaluated the effects of emotional context on encoding and consolidation of aversive and neutral episodic memories."
- PósterThe role of sleep in episodic memory reconsolidation: project and preliminary results(2021) Moyano, Malen D.; Tassone, Leonela M.; Brusco, Luis Ignacio; Wang, Jingyi; Forcato, Cecilia“Episodic memory is a subtype of declarative memory, defined as the ability to remember how, where and when past events occurred. Consolidated memories can be reactivated by a reminder of the original memory and can enter a new labile state, followed by a period of re-stabilization (reconsolidation). Sleep facilitates the consolidation of newly encoded memories and enhances the memory persistence 6 months after learning. It was demonstrated that a short nap accelerated memory re-stabilization of a list of nonsense syllable pairs, and facilitated the reconsolidation of the reactivated object-location memory, at short-term. Here, we aim to study the role of sleep on memory persistence of a neutral episodic memory through the reconsolidation process.”
- PósterVisuospatial perception in subjects with out-body-experiences(2021) Vische, Alejandro; Herrero, Nerea; Forcato, Cecilia; Gallo, Francisco"Visual imagery typically refers to the voluntary creation of the conscious visual experience of an object or scene in its absence, solely in the mind. There are individuals who have no experience of imagery at all –their minds are completely blind: aphantasia. Hyperphantasia is at the other end of the imagery spectrum: strong and often photo-like imagery. One of the key limitations to studying visual imagery has been its internal private and subjective nature. An intrinsic characteristic of the imagery experience is its degree of vividness, the clarity and richness of the mental representation. The most commonly used questionnaire is the vividness of visual imagery questionnaire (VVIQ)."
