Instructions to mimic improve facial emotion recognition in people with sub-clinical autism traits.

People tend to mimic the facial expression of others. It has been suggested that this helps provide social glue between affiliated people but it could also aid recognition of emotions through embodied cognition. The degree of facial mimicry, however, varies between individuals and is limited in people with autism spectrum conditions (ASC). The present study sought to investigate the effect of promoting facial mimicry during a facial-emotion-recognition test. In two experiments, participants without an ASC diagnosis had their autism quotient (AQ) measured. Following a baseline test, they did an emotion-recognition test again but half of the participants were asked to mimic the target face they saw prior to making their responses. Mimicry improved emotion recognition, and further analysis revealed that the largest improvement was for participants who had higher scores on the autism traits. In fact, recognition performance was best overall for people who had high AQ scores but also received the instruction to mimic. Implications for people with ASC are explored.

The role of self-referencing in true and false recognition in young people and healthy older people.

Given the uneven results about the role self-referencing plays in false recognition, we planned an experiment that would allow us to analyze whether self-referencing affects false recognition, and its relationship with healthy aging. A sample of healthy older people (n = 30) and another sample of young people (n = 38) rated whether 40 personality-trait adjectives (20 with a positive valence and 20 with a negative valence) described them or not (self-referencing condition). They then took a recognition test of these adjectives along with 40 other new adjectives. Next, they rated whether 40 other different adjectives described a third person or not (other-referencing condition), and then performed another similar recognition test. These two conditions were counter-balanced across participants. The results clearly showed that self-referencing produces both an increase in true recognition and a decrease in false recognition in both samples. Our results support the idea that self-referencing reduces false recognition by using conscious monitoring strategies, and that self-referencing is a suitable cognitive method for enhancing older individuals’ impaired memory.

Improving Mobile Phone Speech Recognition by Personalized Amplification: Application in People with Normal Hearing and Mild-to-Moderate Hearing Loss.

In this study, the authors evaluated the effect of personalized amplification on mobile phone speech recognition in people with and without hearing loss. This prospective study used double-blind, within-subjects, repeated measures, controlled trials to evaluate the effectiveness of applying personalized amplification based on the hearing level captured on the mobile device. The personalized amplification settings were created using modified one-third gain targets. The participants in this study included 100 adults of age between 20 and 78 years (60 with age-adjusted normal hearing and 40 with hearing loss). The performance of the participants with personalized amplification and standard settings was compared using both subjective and speech-perception measures. Speech recognition was measured in quiet and in noise using Cantonese disyllabic words. Subjective ratings on the quality, clarity, and comfortableness of the mobile signals were measured with an 11-point visual analog scale. Subjective preferences of the settings were also obtained by a paired-comparison procedure. The personalized amplification application provided better speech recognition via the mobile phone both in quiet and in noise for people with hearing impairment (improved 8 to 10%) and people with normal hearing (improved 1 to 4%). The improvement in speech recognition was significantly better for people with hearing impairment. When the average device output level was matched, more participants preferred to have the individualized gain than not to have it. The personalized amplification application has the potential to improve speech recognition for people with mild-to-moderate hearing loss, as well as people with normal hearing, in particular when listening in noisy environments.

Measuring emotion perception following traumatic brain injury: The Complex Audio Visual Emotion Assessment Task (CAVEAT)

ABSTRACTIntroduction: While emotion recognition difficulties in moderate-severe TBI are well established, the standard measures of emotion recognition significantly limit the conclusions which can be drawn regarding real-life deficits. Two studies report on the development of CAVEAT, a new measure of emotion recognition that attempts to overcome these limitations.Method: These studies were designed to establish CAVEAT's psychometric properties by examining performance of a TBI group and matched controls in order to provide estimates of its reliability and validity (study 1), and to compare performance of the TBI and control groups on a subgroup of emotions from the CAVEAT that represented the six basic emotions used in conventional emotion research (study 2). Thirty-two participants with TBI and 32 matched controls (study 1) and 16 participants with TBI and 12 matched controls (study 2) participated in this study.Results: CAVEAT demonstrated high construct validity and internal consistency. Performance on the subgroup of “basic” six emotions was largely similar to the rates reported in the literature.Conclusions: These findings provided some evidence for the psychometric properties of CAVEAT, indicating that it can be used as a clinical test for assessing emotion recognition in people with moderate-severe TBI.

Increased deficits in emotion recognition and regulation in children and adolescents with exogenous obesity

Objectives: In this study we aimed to evaluate emotion recognition and emotion regulation skills of children with exogenous obesity between the ages of 11 and 18 years and compare them with healthy controls.Methods: The Schedule for Affective Disorders and Schizophrenia for School Aged Children was used for psychiatric evaluations. Emotion recognition skills were evaluated using Faces Test and Reading the Mind in the Eyes Test. The Difficulties in Emotions Regulation Scale was used for evaluating skills of emotion regulation.Results: Children with obesity had lower scores on Faces Test and Reading the Mind in the Eyes Test, and experienced greater difficulty in emotional regulation skills.Conclusions: Improved understanding of emotional recognition and emotion regulation in young people with obesity may improve their social adaptation and help in the treatment of their disorder. To the best of our knowledge, this is the first study to evaluate both emotional recognition and emotion regulation functions in obese children and obese adolescents between 11 and 18 years of age.

Effects of hearing and cognitive impairment in sentence recognition.

To evaluate the effects of hearing and cognitive impairment in sentence recognition in elderly people. The study included 30 elderly individuals divided into two groups: GI, with 17 elderly people without hearing loss and GII, with 13 elderly people with mild hearing loss. In order to evaluate their cognition, the Mini Mental State Examination (MMSE) was performed, whereas, for the evaluation of the auditory effects, the Portuguese Sentence List (PSL) was performed, in which the sentence recognition thresholds in silence (SRTS) and the signal-to-noise ratio (S/N) were researched. In MMSE, there was a higher percent of individuals with alteration for GI group when compared with GII group. In both SRTS and S/N, the GI group presented lower thresholds when compared with the GII group for both ears. Regarding the cognitive aspects, no significant statistical difference between normal and altered groups was observed in the MMSE for SRTS and S/N for GI and GII in both ears. Mild hearing loss exerted influence on the sentence recognition in silence and in noise. On the other hand, the cognitive aspects did not interfere in speech recognition in both silence and noise.

The effects of healthy aging, amnestic mild cognitive impairment, and Alzheimer's disease on recollection, familiarity and false recognition, estimated by an associative process-dissociation recognition procedure

Given the uneven experimental results in the literature regarding whether or not familiarity declines with healthy aging and cognitive impairment, we compare four samples (healthy young people, healthy older people, older people with amnestic mild cognitive impairment – aMCI –, and older people with Alzheimer's disease – AD –) on an associative recognition task, which, following the logic of the process-dissociation procedure, allowed us to obtain corrected estimates of recollection, familiarity and false recognition. The results show that familiarity does not decline with healthy aging, but it does with cognitive impairment, whereas false recognition increases with healthy aging, but declines significantly with cognitive impairment. These results support the idea that the deficits detected in recollection, familiarity, or false recognition in older people could be used as early prodromal markers of cognitive impairment.

A study of the meanings and limits of SEALDs as a youth protest movement : from a global and local perspective

This paper examines the meanings and limits of “SEALDs (Students Emergency Action for Liberal Democracy‐s)”as a youth protest movement, appeared in the midst of public opposition and large demonstration against a set of security‐related bills that would allow the Japanese military to fight in foreign conflicts for the first time since World War II. BR Youth protest movements, represented by Occupy Wall Street, los indignados in Spain, Nuit Debout in France in Europe and the Sunflower revolution in Taiwan, the Umbrella revolution in Hong Kong in East Asia have been growing since 2010. Those global movements means young people are faced with difficulty of living in common. However, in the case of SEALDs, we should consider the local (Japanese context) as well as the global background. This results of this paper from local perspective are as follows.BR First, SEALDs were supported by many people, especially liberal intellectuals, because they were conducted by college students who could intellectual and inspirational speech in their own words. They also practiced attractive demonstrations that looked to dispel the image of the violent youth demonstrations of the 1970s.BR Second, members of SEALDs have the desire to escape from a sense of stagnation in lives as well as the desire to keep their lives relatively enriched. This results from the desire of recognition in young people who have lived in the low growth era since 1990.BR Finally, they are relatively elite students and havenʹt had to confront the poverty that the youth in unemployment and non‐regular employment (been increasing recently) encounted in their everyday lives. But, they will soon be faced with the problem of poverty, for example, tuition loan, part‐timer abuse involving college students. In the near future, SEALDs movements will be more energetic as students from different socioeconomic classes are able to find more common ground in global and local.

Sequence Learning with Passive RFID Sensors for Real-Time Bed-Egress Recognition in Older People.

Getting out of bed and ambulating without supervision is identified as one of the major causes of patient falls in hospitals and nursing homes. Therefore, increased supervision is proposed as a key strategy toward falls prevention. An emerging generation of batteryless, lightweight, and wearable sensors are creating new possibilities for ambulatory monitoring, where the unobtrusive nature of such sensors makes them particularly adapted for monitoring older people. In this study, we investigate the use of a batteryless radio-frequency identification (RFID) tag response to analyze bed-egress movements. We propose a bed-egress movement detection framework that includes a novel sequence learning classifier with a set of features derived from bed-egress motion analysis. We analyzed data from 14 healthy older people (66-86 years old) who wore a wearable embodiment of a batteryless accelerometer integrated RFID sensor platform loosely attached over their clothes at sternum level, and undertook a series of activities including bed-egress in two clinical room settings. The promising results indicate the efficacy of our batteryless bed-egress monitoring framework.

Movement cues aid face recognition in developmental prosopagnosia.

Seeing a face in motion can improve face recognition in the general population, and studies of face matching indicate that people with face recognition difficulties (developmental prosopagnosia; DP) may be able to use movement cues as a supplementary strategy to help them process faces. However, the use of facial movement cues in DP has not been examined in the context of familiar face recognition. This study examined whether people with DP were better at recognizing famous faces presented in motion, compared to static. Nine participants with DP and 14 age-matched controls completed a famous face recognition task. Each face was presented twice across 2 blocks: once in motion and once as a still image. Discriminability (A) was calculated for each block. Participants with DP showed a significant movement advantage overall. This was driven by a movement advantage in the first block, but not in the second block. Participants with DP were significantly worse than controls at identifying faces from static images, but there was no difference between those with DP and controls for moving images. Seeing a familiar face in motion can improve face recognition in people with DP, at least in some circumstances. The mechanisms behind this effect are unclear, but these results suggest that some people with DP are able to learn and recognize patterns of facial motion, and movement can act as a useful cue when face recognition is impaired.

The relationship between facial emotion recognition and executive functions in first-episode patients with schizophrenia and their siblings.

BackgroundAlthough many studies have examined executive functions and facial emotion recognition in people with schizophrenia, few of them focused on the correlation between them. Furthermore, their relationship in the siblings of patients also remains unclear. The aim of the present study is to examine the correlation between executive functions and facial emotion recognition in patients with first-episode schizophrenia and their siblings.MethodsThirty patients with first-episode schizophrenia, their twenty-six siblings, and thirty healthy controls were enrolled. They completed facial emotion recognition tasks using the Ekman Standard Faces Database, and executive functioning was measured by Wisconsin Card Sorting Test (WCST). Hierarchical regression analysis was applied to assess the correlation between executive functions and facial emotion recognition.ResultsOur study found that in siblings, the accuracy in recognizing low degree ‘disgust’ emotion was negatively correlated with the total correct rate in WCST (r = −0.614, p = 0.023), but was positively correlated with the total error in WCST (r = 0.623, p = 0.020); the accuracy in recognizing ‘neutral’ emotion was positively correlated with the total error rate in WCST (r = 0.683, p = 0.014) while negatively correlated with the total correct rate in WCST (r = −0.677, p = 0.017). People with schizophrenia showed an impairment in facial emotion recognition when identifying moderate ‘happy’ facial emotion, the accuracy of which was significantly correlated with the number of completed categories of WCST (R2 = 0.432, P < .05). There were no correlations between executive functions and facial emotion recognition in the healthy control group.ConclusionsOur study demonstrated that facial emotion recognition impairment correlated with executive function impairment in people with schizophrenia and their unaffected siblings but not in healthy controls.

Precisión y tiempo de reacción en el reconocimiento de emociones faciales en personas con esclerosis múltiple

Facial emotional expression constitutes a basic guide in the social interaction and, thus, the alterations in its expression or recognition imply an important limitation for the communication. On the other hand, cognitive impairment and the presence of depressive symptoms, which are commonly found in patients with multiple sclerosis, it is unknown how they influence cognitive function and depression on emotional recognition. To consider the evaluation of time reaction and response accuracy of facial expression recognition in people affected by multiple sclerosis, and to assess the possible variables that may be modulating the emotion recognition, such as depression and cognitive functions. The study has a cross-sectional non-experimental design with a single measurement. The sample is compound by 85 participants, 45 diagnosed as multiple sclerosis and 40 control subjects. Multiple sclerosis subjects reveal significant differences in both reaction time and response accuracy in neuropsychological tests in comparison to the control group. Explanatory models were identified in the emotional recognition. Multiple sclerosis subjects face difficulties at recognising facial emotions; and differences at attention memory, processing speed and depressive symptomatology were observed in regard to the control group.

Eye spy: The predictive value of fixation patterns in detecting subtle and extreme emotions from faces

Successful social interaction requires recognizing subtle changes in the mental states of others. Deficits in emotion recognition are found in several neurological and psychiatric illnesses, and are often marked by disturbances in gaze patterns to faces, typically interpreted as a failure to fixate on emotionally informative facial features. However, there has been very little research on how fixations inform emotion recognition in healthy people. Here, we asked whether fixations predicted detection of subtle and extreme emotions in faces. We used a simple model to predict emotion detection scores from participants’ fixation patterns. The best fit of this model heavily weighted fixations to the eyes in detecting subtle fear, disgust and surprise, with less weight, or zero weight, given to mouth and nose fixations. However, this model could not successfully predict detection of subtle happiness, or extreme emotional expressions, with the exception of fear. These findings argue that detection of most subtle emotions is best served by fixations to the eyes, with some contribution from nose and mouth fixations. In contrast, detection of extreme emotions and subtle happiness appeared to be less dependent on fixation patterns. The results offer a new perspective on some puzzling dissociations in the neuropsychological literature, and a novel analytic approach for the study of eye gaze in social or emotional settings.

Dissociation between cognitive and affective empathy in youth with Asperger Syndrome

Autism spectrum conditions, among them Asperger Syndrome (AS), are generally described as entailing deficits in “cognitive empathy” or “theory of mind”. People with AS tend to have difficulties recognizing emotions, although the extent of these difficulties is still unclear. This study aimed to assess empathic profile in youth with AS (N = 38) and controls matched on age, sex and IQ. The study aimed to test if a dissociation between cognitive and affective empathy exists in AS. The study also aimed to explore emotion recognition in people with AS, and how it relates to emotional valence (positive, negative, and neutral emotions). The AS group scored lower than controls on cognitive empathy but scored within the average range on affective empathy. A deficit in emotion recognition was found in the AS group for positive emotions. These results confirm earlier findings in cognitive empathy and provide new insight about emotion recognition abilities in this population.

Size or spacing: which limits letter recognition in people with age-related macular degeneration?

Recent evidence suggests a double dissociation of size and spacing limit on letter recognition-it is limited by size in the fovea and critical spacing in the normal periphery. Here, we evaluated whether size or spacing limits letter recognition in people with age-related macular degeneration (AMD) who must use their peripheral vision. We measured the size threshold for recognizing lowercase letters presented alone, or flanked by two letters at various center-to-center nominal letter spacings (multiples of letter size) for 11 observers with AMD. For comparison, similar measurements were obtained at 5° and 10° eccentricity in the nasal and lower visual fields in three older adults with normal vision. Single-letter size thresholds were worse for observers with AMD than at comparable retinal locations in the normal periphery. For flanked letters, size threshold improved with larger nominal spacing up to the critical spacing, beyond which size threshold was unaffected by the flankers. Seven AMD observers had a nominal critical spacing between 1.25× and 1.80×, values close to those in the normal fovea, suggesting that their letter recognition is size-limited; two had a nominal critical spacing of 3-4×, values close to those in the normal periphery, implying that their letter recognition is limited by spacing; and another two had a nominal critical spacing of ∼2.3×, implying that their letter recognition is limited by both size and spacing. The wide range of nominal critical spacings observed in our AMD observers may reflect the degree of completeness of their adaptation process to vision loss.

Face Recognition and Description Abilities in People with Mild Intellectual Disabilities

People with intellectual disabilities (ID) are as likely as the general population to find themselves in the situation of having to identify and/or describe a perpetrator's face to the police. However, limited verbal and memory abilities in people with ID might prevent them to engage in standard police procedures. Two experiments examined face recognition and description abilities in people with mild intellectual disabilities (mID) and compared their performance with that of people without ID. Experiment 1 used three old/new face recognition tasks. Experiment 2 consisted of two face description tasks, during which participants had to verbally describe faces from memory and with the target in view. Participants with mID performed significantly poorer on both recognition and recall tasks than control participants. However, their group performance was better than chance and they showed variability in performance depending on the measures introduced. The practical implications of these findings in forensic settings are discussed.

Using Diversity Interventions to Increase Cervical Screening of Lesbian and Bisexual Women

AbstractDespite increasing recognition and acceptance in many areas, lesbians, gay men, and bisexual people are still unnoticed service users whose needs the National Health Service (NHS) has not recognized and served well. This article reports the first stages of a small‐scale, practitioner‐led action research study undertaken to increase access to cervical screening for lesbian and bisexual women by planning and delivering service enhancements following in‐depth individual and small‐group interviews with local lesbians and bisexual women. These interviews provided rich data that provided insight into the women's health beliefs and experiences related to cervical screening. These experiences directly informed the enhancements made to cervical screening services. The authors describe the factors that made this action research successful, which may have multiple applications across other diversity interventions.

Evaluating Barten image metric for predicting character recognition in people with low vision

Electronic devices with small visual displays (SVDs) are often inaccessible to the millions of Americans with vision loss. The Barten square root integral (SQRI) is an image quality metric that has been shown to predict whether people with normal vision can see images on a cathode ray tube monitor. The present proof-of-concept study begins to explore whether the same metric could predict the ability of users with low vision to see images on SVDs. In a sample population of 33 adults with low vision, the Barten SQRI was the best predictor of the ability to recognize low-contrast single digits on a screen (r(2) = 0.80, p < 0.01), followed by the Pelli-Robson Contrast Sensitivity Chart (r(2) = 0.69, p < 0.01). Visual acuity was not significantly predictive of the ability to read low-contrast characters on a display. Further work will explore whether the Barten SQRI remains predictive of the ability of people with low vision to use actual devices that have SVDs.

Facial Emotion Recognition in Schizophrenia: The Impact of Gender

ObjectivePrevious studies reported gender differences for facial emotion recognition in healthy people, with women performing better than men. Few studies that examined gender differences for facial emotion recognition in schizophrenia brought out inconsistent findings. The aim of this study is to investigate gender differences for facial emotion identification and discrimination abilities in patients with schizophrenia.Methods35 female and 35 male patients with schizophrenia, along with 35 female and 35 male healthy controls were included in the study. All the subjects were evaluated with Facial Emotion Identification Test (FEIT), Facial Emotion Discrimination Test (FEDT), and Benton Facial Recognition Test (BFRT). Patients' psychopathological symptoms were rated by means of the Positive and Negative Syndrome Scale (PANSS).ResultsMale patients performed significantly worse than female patients on FEIT total, and negative scores. Male controls performed significantly worse than female controls on FEIT total and negative scores. On all tasks, female patients performed comparable with controls. Male patients performed significantly worse than controls on FEIT, and FEDT.ConclusionWomen with schizophrenia outperformed men for facial emotion recognition ability in a pattern that is similar with the healthy controls. It could be claimed that male patients with schizophrenia need special consideration for emotion perception deficits.
