La fragmentación del sueño puede asociarse con distintas enfermedades, entre ellas, la demencia. En este sentido, la fragmentación de sueño, indicada por el índice de alertamientos y/o movimientos ...periódicos de las piernas (MPP), podría ser un marcador temprano de deterioro cognitivo leve (DCL), un síndrome precursor de la demencia. El objetivo del presente estudio fue medir el índice de prevalencia de los alertamientos y de los MPP durante el sueño en un grupo control y un grupo con DCL, así como determinar si hay diferencia entre los grupos en ambos índices y establecer si existe una correlación entre los dos fenómenos. En 9 participantes (3 mujeres controles y 3 mujeres con DCL; y 3 hombres con DCL) (edad: 69.1 ± 5; años de educación: 8 ± 2) se registró una noche de polisomnografía. Se obtuvieron los índices por hora de alertamientos y para cada etapa de sueño, así como los MPP globales y por hora; además se realizaron análisis entre y dentro de cada grupo. Se encontró una correlación positiva y un mayor número de MPP que de alertamientos durante toda la noche en los participantes con DCL. Conocer la prevalencia y asociación de ambos fenómenos contribuye en la formulación de una evaluación más cuidadosa y profunda de los adultos mayores en riesgo de desarrollar DCL y/o demencia.
The current sanitary crisis due to COVID-19 has further evidenced the enormous digital exclusion of older adults. Furthermore, the crisis has urged older adults to adopt new technologies to ...facilitate their tasks, as well as to provide them with an effective means against loneliness and social isolation caused by the confinement. In light of this, Digital Literacy is necessary for all those excluded from the digital era, who are characterized mainly by little or no ability to effectively use technologies. Nevertheless, detailed studies showing the leap from mixed (Blended Learning, BL) to digital literacy in the elderly have not been published. The objective of the present research was to analyze the level of Digital Literacy with the Digital Literacy Evaluation (DILE) of two groups of elderly adults with different levels of literacy (Group 1: G1, and Group 2: G2) during three stages: BL (Aug–Dec 2019); Transition (Feb–Jun 2020); and Digital (Aug–Dec 2020). Comparisons were made before each educational level (pre-pre-pre) and after each educational level (post-post-post) and during consecutive periods before and after each semester (pre vs post) and throughout different educational levels (G1: Basic 1, B1; Basic 2, B2; and intermediate 1, I1; and G2: Intermediate 1 to 3, I1, I2, and I3). Subsequently, considering all the elderly who had passed at least one of the literacy levels, we worked with a total sample of 176 older adults. The comparisons showed that, before the pandemic, G1’s pre digital literacy levels increased between B1 and B2 and that the differences continued with that increasing trend between the B1 level and the I1 completely digital treatment, and the same was observed for post measurements. On the other hand, for the G2, the differences in the DILE were statistically significant between the pre-condition of I2 (before the pandemic) and the I3 (completely digital treatment); and between the pre-conditions of I1 and I3; the same results were obtained for post treatments. Also, pre vs post scores on the DILE were statistically significant and older adults increased progressively their digital literacy despite the COVID-19 pandemic and jumped to the digital age.
Borderline Personality Disorder (BPD) symptoms include inappropriate control of anger and severe emotional dysregulation after rejection in daily life. Nevertheless, when using the Cyberball ...paradigm, a tossing game to simulate social exclusion, the seven basic emotions (happiness, sadness, anger, surprise, fear, disgust, and contempt) have not been exhaustively tracked out. It was hypothesized that these patients would show anger, contempt, and disgust during the condition of exclusion versus the condition of inclusion. When facial emotions are automatically detected by Artificial Intelligence, “blending”, -or a mixture of at least two emotions- and “masking”, -or showing happiness while expressing negative emotions- may be most easily traced expecting higher percentages during exclusion rather than inclusion. Therefore, face videos of fourteen patients diagnosed with BPD (26 ± 6 years old), recorded while playing the tossing game, were analyzed by the FaceReader software. The comparison of conditions highlighted an interaction for anger: it increased during inclusion and decreased during exclusion. During exclusion, the masking of surprise; i.e., displaying happiness while feeling surprised, was significantly more expressed. Furthermore, disgust and contempt were inversely correlated with greater difficulties in emotion regulation and symptomatology, respectively. Therefore, the automatic detection of emotional expressions during both conditions could be useful in rendering diagnostic guidelines in clinical scenarios.
Cheating forms part of a complex emotional and cognitive process. However, although a relatively mundane phenomenon, instruments to evaluate cheating and its effects socially are scarce. This paper ...presents a five-stage approach aimed at providing validity to an instrument designed to assess cheating - specifically, its detection, and emotional reactions towards it once detected. An instrument was designed after (1) reviewing the relevant literature on cheating, in order to (2) design a bank of stimuli, (3) formulate a Delphi panel to judge the most coherent and pertinent ones, and (4) perform three pilot studies to adjust the final version of the instrument. Results from Stages 1 to 4 show that content validity was achieved for the Instrument for Detecting Cheating and its Emotional Reactions (INDETRAE, in Spanish:
). Stimuli were grouped into five categories of 18 different scenarios, for a total of 90 vignettes: meaning, the INDETRAE is a 5-category, vignette-based questionnaire consisting of contrasting social cost-benefit scenarios, where the cheating situation affects an undefined, a first or a third person, and also a neutral category with no cheating. In Stage 5, several chi-squared tests (
< 0.0005) revealed significant differences between categories, proving that the instrument can indeed be used to detect cheating and to identify differentiated emotional reactions - for example, anger when there was detriment to a third person as opposed to neutral situations, or glad when there was a case of cheating which benefited the first person. The last stage counts as the first approximation to support construct validity of the INDETRAE. The most important contribution of this work consists in developing an instrument to detect cheating, confirmed by the resulting emotional reactions, which therefore demonstrate its validity.
Background
The detection of non‐amnestic Mild Cognitive Impairment with difficult tasks as the Wisconsin Card Sorting Test (WCST) is still under debate. Associations concerning performance and/or ...speed are not usually evaluated even though speed decreases with age and so, the WCST may be preferentially administered in a computerized format. Therefore, 3 types of relationships were looked for: 1) between reaction times (RT) of correct and incorrect answers; 2) between the percentage of correct responses and RT of correct responses; and lastly, 3) between the percentage of incorrect responses and RT of incorrect responses.
Method
Two age groups, one group of executives of the INEGI (National Institute of Statistics, Geography and Informatics) (n = 12, 46.71 ± 5) and another one of older adults (OAs) who attended a “Centro Gerontológico Integral” in the state of Hidalgo in Mexico (n = 17, 66.35 ± 6) were evaluated.
Result
The RT of correct and incorrect performances were highly correlated for both groups (INEGI group: r = 0.80, p = 0.01; OAs: r = 0.89, p = 0.01). Instead, the correlations between performance and speed were only negatively related for the percentage of correct responses and RT of correct responses in the group of the INEGI (r = ‐ 0.72, p = 0.02), while they had a tendency to be positive in OAs although not significant (r = 0.43, p = 0.10). The percentage of incorrect responses and RT of incorrect responses was positive and significant for the group of the INEGI (r = 0.84, p = 0.01) and tended to be negative and not significant for OAs (r = ‐ 0.48, p = 0.10).
Conclusion
A positive correlation between RT of correct and incorrect answers was found, suggesting a consistent speed within subjects no matter the performance. A negative correlation was found for the percentage of correct responses and RT of correct responses in the group of the INEGI. However, this late relationship and the one concerning wrong performance was not confirmed for OAs, indicating that speed when decision making and problem solving are assessed suffer from severe alterations with age.
Converging evidence from animal and human studies suggest that rapid eye movement (REM) sleep modulates emotional processing. The aim of the present study was to explore the effects of selective REM ...sleep deprivation (REM-D) on emotional responses to threatening visual stimuli and their brain correlates using functional magnetic resonance imaging (fMRI). Twenty healthy subjects were randomly assigned to two groups: selective REM-D, by awakening them at each REM sleep onset, or non-rapid eye movement sleep interruptions (NREM-I) as control for potential non-specific effects of awakenings and lack of sleep. In a within-subject design, a visual emotional reactivity task was performed in the scanner before and 24 h after sleep manipulation. Behaviorally, emotional reactivity was enhanced relative to baseline (BL) in the REM deprived group only. In terms of fMRI signal, there was, as expected, an overall decrease in activity in the NREM-I group when subjects performed the task the second time, particularly in regions involved in emotional processing, such as occipital and temporal areas, as well as in the ventrolateral prefrontal cortex, involved in top-down emotion regulation. In contrast, activity in these areas remained the same level or even increased in the REM-D group, compared to their BL level. Taken together, these results suggest that lack of REM sleep in humans is associated with enhanced emotional reactivity, both at behavioral and neural levels, and thus highlight the specific role of REM sleep in regulating the neural substrates for emotional responsiveness.
