See me, feel me. Using physiology to validate behavioural observations of emotions of people with severe or profound intellectual disability

The missing piece. Physiological data as a factor for identifying emotions of people with profound intellectual and multiple disabilities

Introduction: The preferences of people with profound intellectual and multiple disabilities (PIMD) often remain unfulfilled since it stays challenging to decode their idiosyncratic behavior resulting in a negative impact on their quality of life (QoL). Physiological data (i.e. heart rate (variability) and motion data) might be the missing piece for identifying emotions of people with PIMD, which positively affects their QoL. Method: Machine learning (ML) processes and statistical analyses are integrated to discern and predict the potential relationship between physiological data and emotional states (i.e. numerical emotional states, descriptive emotional states and emotional arousal) in everyday interactions and activities of two participants with PIMD. Results: Emotional profiles were created enabling a differentiation of the individual emotional behavior. Using ML classifiers and statistical analyses, the results regarding the phases partially confirm previous research, and the findings for the descriptive emotional states were good and even better for the emotional arousal. Conclusion: The results show the potential of the emotional profiles especially for practitioners and the possibility to get a better insight into the emotional experience of people with PIMD including physiological data. This seems to be the missing piece to better recognize emotions of people with PIMD with a positive impact on their QoL.

Meaningful moments of interaction with people with profound intellectual disabilities: Reflections from direct support staff

BACKGROUND

High-quality, affective relationships are built on meaningful moments of interaction, which are challenging for support staff to establish with people with profound intellectual disabilities. Therefore, we explored what makes a moment of interaction meaningful to support staff and what circumstances facilitate meaningful moments of interaction taking place.

METHOD

Five direct support staff took part in unstructured, in-depth interviews. The interviews were analysed using interpretative phenomenological analysis (IPA). Member checks were also conducted.

RESULTS

Support staff experienced moments of interaction as meaningful because they felt a connection with a person with profound intellectual disabilities and/or they had the feeling of being meaningful for this person. Staff-related and contextual circumstances facilitating meaningful moments of interaction to take place were described.

CONCLUSIONS

Meaningful moments of interaction are highly valued by support staff, who believe these moments are valued by persons with profound intellectual disabilities as well. Implications for daily practice are described.

The intellectual ableism of leisure research: Original considerations towards understanding well-being with and for people with intellectual disabilities

People with intellectual disabilities (IDs) are considered to be one of the most marginalized, isolated and disenfranchised groups in society. However, recent social prescription intervention programmes are being introduced to enhance the physical and mental well-being of these individuals through participation in leisure activities, thus increasing academic interest in research within the area. This article introduces the theoretical and methodological tensions in applying mainstream scholarly thinking of leisure and well-being to people with IDs and argues that by failing to acknowledge and address such tensions scholars are at risk of demonstrating intellectual ableism. Layering Kleiber's components of leisure over Seligman's Positive Emotion, Engagement, Relationships, Meaning, and Accomplishment concept of well-being, this article poses critical questions of how each contributing element of well-being could be reconceptualized for people with neurological diversities. The intersection of leisure, well-being and ID is ripe for research development; however, many studies in the domain are falling short of suitable theoretical discussion and methodological rigour. This article concludes with suggestions on how scholars can reduce intellectual ableism through inclusive design, methodological reporting, acknowledging bias and grappling theoretical dissonance.

Looking back, looking forward: Methodological challenges and future directions in research on persons with profound intellectual and multiple disabilities

BACKGROUND

Within the context of the Special Interest Research Group (SIRG) on Persons with Profound Intellectual and Multiple Disabilities (PIMD), researchers often discuss the methodological problems and challenges they are confronted with. The aim of the current article was to give an overview of these challenges.

METHODS

The challenges are centred on six topics. These reflect the main components of a study's design: (a) participant demarcation, (b) participant recruitment, (c) data collection and instruments, (d) data analysis, (e) ethics/including the "voice" of persons with PIMD and (f) theoretical models.

RESULTS

Next, to describing the specific challenges, possible solutions and pathways to address them are discussed. These are illustrated by recent studies by the authors and other researchers in the field.

CONCLUSIONS

The current contribution wants to stimulate further discussion and exchange of ideas, and the development of creative research techniques.

Orienting to affect in services for people with severe or profound intellectual disabilities: A UK-based investigation

BACKGROUND

This study argues for displays of affect by people with severe or profound intellectual disabilities to be analysed in the course of everyday interactions with the people who support them.

METHOD

Conversation analysis is applied to the affective displays of residents of a social care service for people with severe or profound intellectual disabilities to identify how such displays are taken up and form the basis for further action.

RESULTS

Three types of orientations to affect are identified: where the cause of the affect is unknown; where there is a proximal cause; and where the proximal cause is a prior action by a member of staff. Staff orient to affect as expressions of both feelings and cognitions, thereby providing the basis for self-determination.

CONCLUSIONS

Displays of affect are a communicative resource for those with severe or profound impairments and must be studied in situ if they are to inform policy and everyday practice.

Comfort provided by parents versus strangers after eliciting stress in children with severe or profound intellectual disabilities: does it make a difference?

The relationships between children with severe or profound intellectual disabilities (ID) and their parents may fulfil attachment functions, such as regulating emotional responses to stress. This study examined the extent to which children with severe or profound ID differentiate between their parents and a stranger as a resource for stress-regulation. A home-based experimental paradigm was conducted and video-recorded in 38 families. Children (1-8 years) were exposed to four naturalistic stressors followed by comfort, randomly provided by the parents or the stranger. Emotional behaviour (arousal and valence) and the skin conductance level were simultaneously recorded. With regard to both emotional behaviour and skin conductance, children significantly differentiated between their parents as attachment figures and the stranger during stress and comfort, despite their impairments on various developmental domains. Behavioural observation and physiology show complementary manifestations of parent-child attachment in this population.

The effects of a bioresponse system on the joint attention behaviour of adults with visual and severe or profound intellectual disabilities and their affective mutuality with their caregivers

BACKGROUND

The subtle communicative behaviour of individuals with visual and severe/profound intellectual disabilities hinders the success of their interaction with professional caregivers. The bioresponse system, a tool to raise caregivers' awareness of the client's communicative behaviour, may improve the client's joint attention behaviour and the dyad's affective mutuality.

METHOD

Four client-caregiver dyads participated in a randomized multiple baseline study with repeated baseline, intervention and follow-up observations. The bioresponse system's effect was evaluated with measures of joint attention and affective mutuality.

RESULTS

Two clients showed a significant difference on one or two joint attention subscales (including one significant decrease), and for all clients, at least one joint attention subscale revealed a positive trend. Positive trends in affective mutuality scores were observed in two dyads.

CONCLUSIONS

The results stress the importance of further research to the effects of using the bioresponse system's in daily care for persons with severe/profound intellectual disabilities.

Emotional expression in psychiatric conditions: New technology for clinicians

AIM

Emotional expressions are one of the most widely studied topics in neuroscience, from both clinical and non-clinical perspectives. Atypical emotional expressions are seen in various psychiatric conditions, including schizophrenia, depression, and autism spectrum conditions. Understanding the basics of emotional expressions and recognition can be crucial for diagnostic and therapeutic procedures. Emotions can be expressed in the face, gesture, posture, voice, and behavior and affect physiological parameters, such as the heart rate or body temperature. With modern technology, clinicians can use a variety of tools ranging from sophisticated laboratory equipment to smartphones and web cameras. The aim of this paper is to review the currently used tools using modern technology and discuss their usefulness as well as possible future directions in emotional expression research and treatment strategies.

METHODS

The authors conducted a literature review in the PubMed, EBSCO, and SCOPUS databases, using the following key words: 'emotions,' 'emotional expression,' 'affective computing,' and 'autism.' The most relevant and up-to-date publications were identified and discussed. Search results were supplemented by the authors' own research in the field of emotional expression.

RESULTS

We present a critical review of the currently available technical diagnostic and therapeutic methods. The most important studies are summarized in a table.

CONCLUSION

Most of the currently available methods have not been adequately validated in clinical settings. They may be a great help in everyday practice; however, they need further testing. Future directions in this field include more virtual-reality-based and interactive interventions, as well as development and improvement of humanoid robots.

Young children with significant developmental delay differentiate home observed attachment behaviour towards their parents

BACKGROUND

The hallmark of attachment is that contact, proximity and relief from stress are sought from specific individuals, laying important groundwork for healthy socioemotional functioning. This study investigated the extent to which differentiated attachment behaviour can be observed in young children with significant developmental delay (DD).

METHOD

Video-taped observations of the parent-child and stranger-child interaction were conducted at home and complemented with questionnaires in 20 families with a child with significant DD (age 2-7 years with an average DD of 49 months).

RESULTS

Children displayed more intense and persistent contact-seeking, contact-maintaining and resistant behaviour in the episodes with their parent compared to the episodes with the stranger. Parent-reported secure attachment behaviour was slightly more characteristic towards mother compared to father.

CONCLUSIONS

Even children with significant DD develop differentiated attachment behaviour. Detailed observations may support parents in identifying the interactions that make the attachment relationship with their child special.

Using pupil size and heart rate to infer affective states during behavioral neurophysiology and neuropsychology experiments

BACKGROUND

Nonhuman primates (NHPs) are a valuable research model because of their behavioral, physiological and neuroanatomical similarities to humans. In the absence of language, autonomic activity can provide crucial information about cognitive and affective states during single-unit recording, inactivation and lesion studies. Methods standardized for use in humans are not easily adapted to NHPs and detailed guidance has been lacking.

NEW METHOD

We provide guidance for monitoring heart rate and pupil size in the behavioral neurophysiology setting by addressing the methodological issues, pitfalls and solutions for NHP studies. The methods are based on comparative physiology to establish a rationale for each solution. We include examples from both electrophysiological and lesion studies.

RESULTS

Single-unit recording, pupil responses and heart rate changes represent a range of decreasing temporal resolution, a characteristic that impacts experimental design and analysis. We demonstrate the unexpected result that autonomic measures acquired before and after amygdala lesions are comparable despite disruption of normal autonomic function.

COMPARISON WITH EXISTING METHODS

Species and study design differences can render standard techniques used in human studies inappropriate for NHP studies. We show how to manage data from small groups typical of NHP studies, data from the short behavioral trials typical of neurophysiological studies, issues associated with longitudinal studies, and differences in anatomy and physiology.

CONCLUSIONS

Autonomic measurement to infer cognitive and affective states in NHP is neither off-the-shelf nor onerous. Familiarity with the issues and solutions will broaden the use of autonomic signals in NHP single unit and lesion studies.

An Exploration of Comfort and Discomfort Amongst Children and Young People with Intellectual Disabilities Who Depend on Postural Management Equipment

BACKGROUND

The natural response to the intrusive bodily sensation is positional change. This study explored how children and young people (CYP) with intellectual disabilities had their comfort needs met when using adaptive positioning equipment.

METHODS

Thirteen qualitative case studies were undertaken. A parent, a teacher/key worker and a therapist for each CYP were interviewed, and daily routines were observed, with selective video recording. Single case and cross case analyses were undertaken.

RESULTS

Attentive caregivers read the behavioural expressions of the CYP and responded reassuringly, safeguarding them from discomforting experiences. Threats to comfort include the restrictive nature of some equipment accessories, positioning errors and procedural stretching.

CONCLUSIONS

The same item of equipment can be both comfortable and uncomfortable. Given the social and interactional world in which the CYP live and learn, it is others who must accept responsibility for ensuring their optimal level of comfort.

Investigating the relationship between observed mood and emotions in people with severe and profound intellectual disabilities

BACKGROUND

The measurement of subjective well-being in people with severe and profound intellectual disabilities (ID) is a difficult challenge. As they cannot self-report about their life satisfaction, because of severe communicative and cognitive limitations, behavioural observations of their emotions and moods are important in the measurement of their subjective well-being. It is, however, not known if observations of mood and emotion can be differentiated in people with severe and profound ID and if mood and emotions can give unique information about their affect. Therefore, the aim of this study is to examine the relationship between mood and emotions in people with severe and profound ID, using behavioural observations. As recommended in the literature, we investigated the frequency and intensity of the emotion separately.

METHOD

In a period of 3 weeks 27 participants with severe and profound ID were presented with four staff-selected negative and four staff-selected positive stimuli. During the presentation participants were videotaped using the observational method of Petry & Maes where each behaviour is coded on a 5-point scale, ranging from indicating a very negative emotion to indicating a very positive emotion. As a measure of mood, the staff completed the MIPQ in the beginning of the 3 weeks.

RESULTS

We found a positive relationship between mood and respectively the total emotion score and the frequency of the emotion when the stimuli were positive but not when the stimuli were negative. There was no relationship between mood and the intensity of the emotion.

CONCLUSIONS

Our results indicate that mood and emotions can be distinguished from each other using behavioural observations. Both can give specific information about the affective life of people with severe or profound ID. Moreover, if further research could replicate the results of this study, an implication is that the direct support workers should be aware of a decline in the frequency of their clients reactions to positive stimuli as this could indicate a decline in their mood.
