Female victims of abuse, as well as suffering from psychopathological disorders such as depression, can have neuropsychological sequelae affecting memory and attention, with serious consequences, both physical and psychological, in their daily lives. Therefore, the objective of this study is to analyse these sequelae that affect attention and memory, as well as the possible association of these sequelae to depression. A total of 68 women, victims of gender-based violence, between the ages of 15 and 62 participated in this study. The Luria DNA Battery (Neuropsychological Diagnosis of Adults) by Manga and Ramos (2000); and the Beck Depression Inventory (2011) were applied. It is shown that female victims of gender-based violence present poor short-term memory, attentional control, and score low on the Luria-DNA battery. Of these women, 60% suffer from some relevant type of depression. Through HJ-Biplot analysis, a direct relationship was found between memory and attentional control with the total score of the Luria battery. However, an inverse relationship was found between short-term memory and depression. In addition, three well-differentiated clusters of female victims of gender-based violence were identified. It is concluded that a lower rate of depression is observed in female victims of abuse when they have a more intact short-term memory.

Abstract Background Multiple Sclerosis (MS) is a chronic condition of the central nervous system, affecting around 1 in every 600 people in the UK, with 130 new diagnoses every week. Cognitive difficulties are common amongst people with MS, with up to 70% experiencing deficits in higher-level brain functions – such as planning and problem-solving, attention, and memory. Cognitive deficits make it difficult for people with MS to complete everyday tasks and limit their abilities to work, socialise, and live independently. There is a clear need – and recognised research priority – for treatments that can improve cognitive functioning in people with MS. The absence of effective cognitive interventions exacerbates burdens on the services accessed by people with MS – requiring these services to manage sequelae of untreated cognitive deficits, including reduced quality of life, greater disability and dependence, and poorer adherence to disease-modifying treatments. Our planned research will fill the evidence gap through developing – and examining the feasibility of trialling – a novel online cognitive rehabilitation programme for people with MS (SMART). Methods The primary objective of this study aims to conduct a feasibility study to inform development of a definitive trial of SMART for improving cognitive functioning in people with MS. Secondary objectives include accessing the acceptability to participants of the intervention, delivery format, inclusion/exclusion criteria, baselines and outcome measures, randomisation protocol, and the study procedures. It will further assess the framework for a cost-effectiveness analysis alongside a definitive trial; participant recruitment and retention rates, sample-size needed for a fully powered trial, and signal of efficacy. Discussion As a feasibility trial, outcomes are unlikely to immediately effect changes to NHS practice. However, this is a necessary step towards developing a definitive trial – and will give us a signal of efficacy, a prerequisite for progression to a definitive trial. If found to be clinically- and cost-effective, the latter trial could create a step-change in MS cognitive rehabilitation – improving service-delivery and optimising support with limited additional resources.

Background and Objective: Attention and memory are essential aspects of cognitive health. Yogasanas, pranayama, and meditation have shown to improve cognitive functions. There has been no assessment of Trataka (yogic visual concentration) on working or on spatial memory. The present study was planned to assess the immediate effects of Trataka and of eye exercise sessions on the Corsi-block tapping task (CBTT).Methods: A total of 41 healthy volunteers of both genders with age 23.21 ± 2.81 years were recruited. All participants underwent baseline assessment, followed by 2 weeks of training in Trataka (including eye exercise). Each training session lasted for 20 min/day for 6 days a week. After completion of the training period, a 1-week washout period was given. Each participant then was assessed in two sessions in Trataka and in eye exercise on two separate days, maintaining the same time of the day. Repeated measure analysis of variance with Holm’s adjustment was performed to check the difference between the sessions.Results: Significant within-subjects effects were observed for forward Corsi span andforward total score (p < 0.001), and also for backward Corsi span (p < 0.05) and backward total score (p < 0.05). Post hoc analyses revealed Trataka session to be better than eye exercises and baseline. The eye exercise session did not show any significant changes in the CBTT.Conclusion: The result suggests that Trataka session improves working memory, spatial memory, and spatial attention.

The brain supports adaptive behavior by generating predictions, learning from errors, and updating memories to incorporate new information. Prediction error, or surprise, triggers learning when reality contradicts expectations. Prior studies have shown that the hippocampus signals prediction errors, but the hypothesized link to memory updating has not been demonstrated. In a human functional MRI study, we elicited mnemonic prediction errors by interrupting familiar narrative videos immediately before the expected endings. We found that prediction errors reversed the relationship between univariate hippocampal activation and memory: greater hippocampal activation predicted memory preservation after expected endings, but memory updating after surprising endings. In contrast to previous studies, we show that univariate activation was insufficient for understanding hippocampal prediction error signals. We explain this surprising finding by tracking both the evolution of hippocampal activation patterns and the connectivity between the hippocampus and neuromodulatory regions. We found that hippocampal activation patterns stabilized as each narrative episode unfolded, suggesting sustained episodic representations. Prediction errors disrupted these sustained representations and the degree of disruption predicted memory updating. The relationship between hippocampal activation and subsequent memory depended on concurrent basal forebrain activation, supporting the idea that cholinergic modulation regulates attention and memory. We conclude that prediction errors create conditions that favor memory updating, prompting the hippocampus to abandon ongoing predictions and make memories malleable.

A topic of interest is the way decoding and interpreting facial emotional expressions can lead to mutual understanding. Facial emotional expression is a basic source of information that guarantees the functioning of other higher cognitive processes (e.g., empathy, cooperativity, prosociality, or decision-making, among others). In this regard, hormones such as oxytocin, cortisol, and/or testosterone have been found to be important in modifying facial emotion processing. In fact, brain structures that participate in facial emotion processing have been shown to be rich in receptors for these hormones. Nonetheless, much of this research has been based on correlational designs. In recent years, a growing number of researchers have tried to carry out controlled laboratory manipulation of these hormones by administering synthetic forms of these hormones. The main objective of this study was to carry out a systematic review of studies that assess whether manipulation of these three hormones effectively promotes significant alterations in facial emotional processing. To carry out this review, PRISMA quality criteria for reviews were followed, using the following digital databases: PsycINFO, PubMed, Dialnet, Psicodoc, Web of Knowledge, and the Cochrane Library, and focusing on manuscripts with a robust research design (e.g., randomized, single- or double-blind, and/or placebo-controlled) to increase the value of this systematic review. An initial identification of 6340 abstracts and retrieval of 910 full texts led to the final inclusion of 101 papers that met all the inclusion criteria. Only about 18% of the manuscripts included reported a direct effect of hormone manipulation. In fact, emotional accuracy seemed to be enhanced after oxytocin increases, but it diminished when cortisol and/or testosterone increased. Nonetheless, when emotional valence and participants’ gender were included, hormonal manipulation reached significance (in around 53% of the articles). In fact, these studies offered a heterogeneous pattern in the way these hormones altered speed processing, attention, and memory. This study reinforces the idea that these hormones are important, but not the main modulators of facial emotion processing. As our comprehension of hormonal effects on emotional processing improves, the potential to design good treatments to improve this ability will be greater.

Abstract Background The current study used eye tracking to investigate attention and recognition memory in Phelan-McDermid syndrome (PMS), a rare genetic disorder characterized by intellectual disability, motor delays, and a high likelihood of comorbid autism spectrum disorder (ASD). Social deficits represent a core feature of ASD, including decreased propensity to orient to or show preference for social stimuli. Methods We used a visual paired-comparison task with both social and non-social images, assessing looking behavior to a novel image versus a previously viewed familiar image to characterize social attention and recognition memory in PMS (n = 22), idiopathic ASD (iASD, n = 38), and typically developing (TD) controls (n = 26). The idiopathic ASD cohort was divided into subgroups with intellectual disabilities (ID; developmental quotient < 70) and without (developmental quotient > 70) and the PMS group into those with and without a co-morbid ASD diagnosis. Results On measures of attention, the PMS group with a comorbid ASD diagnosis spent less time viewing the social images compared to non-social images; the rate of looking back and forth between images was lowest in the iASD with ID group. Furthermore, while all groups demonstrated intact recognition memory when novel non-social stimuli were initially presented (pre-switch), participants with PMS showed no preference during the post-switch memory presentation. In iASD, the group without ID, but not the group with ID, showed a novelty preference for social stimuli. Across indices, individuals with PMS and ASD performed more similarly to PMS without ASD and less similarly to the iASD group. Conclusion These findings demonstrate further evidence of differences in attention and memory for social stimuli in ASD and provide contrasts between iASD and PMS.

The SKT (Syndrom-Kurz-Test) is a well-established short cognitive performance test for the detection of attention and memory deficits in Germany. The goal of this paper is to test whether the SKT could be applied to English-speaking populations to screen cognitive impairments in the US, Australia, and Ireland. A regression-based continuous norming technique was applied. Standardized test results obtained from German-speaking (n = 1056) and English-speaking (n = 285) samples were compared. Both samples consisted of cognitively unimpaired, community-dwelling, and independently living volunteers (non-patients) over 60 years of age. Means, medians, and standard deviations of raw scores were calculated. A high similarity in the raw value distributions of the criterion variables and a comparison of German and English multiple regression residuals indicated the equivalence among the samples. In addition, the obtained multiple regression equations for predicting the subtest scores including the explained variances (R2) were highly comparable. Age and intelligence turned out to be the most important and necessary predictors for each subtest performance. The results suggest that the new regression-based norming of the SKT can be validly used in the three English-speaking countries.

PurposeThe main purpose of this study is to demonstrate and verify the influence of emotional intelligence skills on the performance of teachers in private higher educational institutions.Design/methodology/approachThis quantitative study is based on the positivism research philosophy and the deductive research. Data are collected form Lebanese educational institutions; 304 teachers are surveyed using the convenience sampling technique. Hypotheses are verified through the one-way ANOVA and the multiple linear regression (step-wise) technique with a Sig. value of 0.000 < 0.05.FindingsThe study verified that teachers' demographics have a direct impact on their performance. It also proved that emotions have an impact on teachers' behaviors; emotions are important energy re-sources that help them cope with difficult situations. Teachers with a high level of emotional intelligence are in tune with their own emotions. It is demonstrated that self-awareness, self-management, self-motivation and social skill have a positive statistical influence on the teacher's performance. Lebanese Private Educational Institutions system should be endowed with emotional intelligence to provide teachers with more effective abilities which would eventually reflect on the student's cognitive abilities especially attention and memory.Originality/valueThis study contributes to the literature by studying the emotional intelligence in Lebanese educational institutions which was studied in different countries except Lebanon. It is verified that integrating the emotional intelligence into Lebanese educational systems would play a decisive role in optimum academic performance; institutions should establish as a benchmark the skills related to emotional intelligence.

Besides motor symptoms, people with Parkinson’s Disease (PD) often exhibit social cognition difficulties. The assessment of social cognition in early PD is crucial, as these deficits may impact patients' social interactions and quality of life. The current study used naturalistic, dynamic video clips to examine the ability of individuals with idiopathic PD to perceive speaker intentions in comparison with healthy controls (HC). Neuropsychological evaluation of the PD patients was conducted using the Cognitive Linguistic Quick Test (CLQT). Video stimuli were taken from the Relational Inference in Social Communication database (RISC; Rothermich &amp; Pell, 2015) and contained literal, sarcastic, and teasing scenes. The participant’s task was to identify the speaker’s belief, i.e., if they were sincere or insincere. The results show that in general, all participants had a harder time identifying nonliteral statements such as teasing as insincere when compared to literal statements. A group analysis demonstrated a marginally significant effect between people with PD and HCs, showing that individuals with PD were less accurate in recognizing social intent compared to HC. This difference was possibly driven by changes in cognitive abilities due to the progression of PD. Indeed, analyses for the PD group revealed positive correlations between several cognitive domains, such as attention and memory, and performance on the speaker belief task. Taken together, our study sheds light on the relationship between cognitive mechanisms and social perception impairments in PD and supports the development of targeted tools for diagnosing and treating these impairments.
