The Non-Standardization of Attention Deficit Hyperactive Disorder: A Call to Action
Attention Deficit Hyperactive Disorder (ADHD) is one of the most diagnosed disorders in adults and children, yet there is no standardized method to assess for ADHD. The similarity of symptoms shared across other disorders (comorbidity) makes the assessment of ADHD a very delicate process. This is not aided by the fact that the assessment of ADHD is not standardized. This allows individuals able to assess for ADHD to give a test or a combination of tests that they find fitting. This in turn brings into question the quality of testing and disagreement in diagnosing across fields. Lastly, ADHD-focused measures typically fail to address the overlap in symptoms with other disorders, which can help assist clinicians with differential diagnoses. The question then becomes, how does one attempt to standardize ADHD testing while providing testing that shows adequate clinical validity in both the diagnosis of ADHD and differential diagnosing? This paper aims to produce insight into the complications of ADHD diagnosis and suggest a solution to current testing, in the form of an assessment battery
Derogatory, Racist, and Discriminatory Speech (DRDS) in Video Gaming
Video games have been examined for their effects on cognition, learning, health, and physiological arousal, yet research on social dynamics within video gaming is limited. Studies have documented the presence of derogation, racism, and discrimination in this anonymous medium. However, gamers‟ firsthand experiences are typically examined qualitatively. Thus, this study aimed to establish a quantitative baseline for the frequency of derogatory, racist, and discriminatory speech (DRDS) in gaming. DRDS frequency, sexual harassment, and hate speech measures were administered to 150 individuals from online forums and social media groups. Descriptive and inferential analyses were used to gauge which factors affected DRDS rates. Sex, intergroup and fast-paced game types, time played with others, and identity portrayal showed positive correlations with DRDS. Results indicate an array of complex social and developmental factors contribute to experiencing, perceiving, and personally using DRDS. Implications include psychosocial health impacts similar to everyday harassment, with women being at a higher risk and age as a contributing factor
The self and conscious experience
The primary determinant of the self (S) is the conscious experience (CE) we have of it. Therefore, it does not come as a surprise that empirical research on S mainly resorts to the CE (or lack of CE) that subjects have of their S. What comes as a surprise is that empirical research on S does not tackle the problem of how CE contributes to building S. Empirical research investigates how S either biases the cognitive processing of stimuli or is altered through a wide range of means (meditation, hypnosis, etc.). In either case, even for different reasons, considerations of how CE contributes to building S are left unspecified in empirical research. This article analyzes these reasons and proposes a theoretical model of how CE contributes to building S. According to the proposed model, the phenomenal aspect of consciousness is produced by the modulation—engendered by attentional activity—of the energy level of the neural substrate (that is, the organ of attention) that underpins attentional activity. The phenomenal aspect of consciousness supplies the agent with a sense of S and informs the agent on how its S is affected by the agent’s own operations. The phenomenal aspect of consciousness performs its functions through its five main dimensions: qualitative, quantitative, hedonic, temporal, and spatial. Each dimension of the phenomenal aspect of consciousness can be explained by a specific aspect of the modulation of the energy level of the organ of attention. Among other advantages, the model explains the various forms of S as outcomes resulting from the operations of a single mechanism and provides a unifying framework for empirical research on the neural underpinnings of S
Exploring cognitive mechanisms involved in self-face recognition
Due to the own face being a significant stimulus that is critical to one’s identity, the own face is suggested to be processed in a quantitatively different (i.e., faster and better recognition) and qualitatively different (i.e., processed in a more featural manner) manner compared to other faces. This thesis further explored the cognitive mechanisms (perceptual and attentional systems) involved in the processing of the own face.
Chapter 2 explored the role of holistic and featural processing involved in the processing of self-face (and other faces) with eye-tracking measures in a passive-viewing paradigm and a face identification task. In the passive-viewing paradigm, the own face was sampled in a more featural manner compared to other faces whereas when asked to identify faces, all faces were sampled in a more holistic manner. Chapter 3 further explored the role of holistic and featural processing in the identification of the own face using the three standard measures of holistic face processing: The face inversion task, the composite face task, and the part-whole task. Compared to other faces, individuals showed a smaller “holistic interference” by a task irrelevant bottom half for the own face in the composite face task and a stronger feature advantage for the own face, but inversion impaired the identification of all faces. These findings suggest that self-face is processed in a more featural manner, but the findings do not deny the role of holistic processing.
The final experimental chapter, Chapter 4, explored the modulation effects of cultural differences in one’s self-concept (i.e., independent vs. interdependent self-concept) and a negative self-concept (i.e., depressive traits) on the attentional prioritization for the own face with a visual search paradigm. Findings showed that the attentional prioritization for the own face over an unfamiliar face is not modulated by cultural differences of one’s self-concept nor one’s level of depressive traits, and individuals showed no difference in the attentional prioritization for both the own face and friend’s face, demonstrating no processing advantage for the own face over a personally familiar face. These findings suggests that the attentional prioritization for the own face is better explained by a familiar face advantage.
Altogether, the findings of this thesis suggest that the own face is processed qualitatively different compared to both personally familiar and unfamiliar face, with the own face being processed in a more featural manner. However, in terms of quantitative differences, the self-face is processed differently compared to an unfamiliar face, but not to a familiar face. Although the specific face processing strategies for the own face may be due to the distinct visual experience that one has with their face, the attentional prioritization of the own face is however, better explained by a familiar face advantage rather than a self-specificity effect
ACOUSTIC SPEECH MARKERS FOR TRACKING CHANGES IN HYPOKINETIC DYSARTHRIA ASSOCIATED WITH PARKINSON’S DISEASE
Previous research has identified certain overarching features of hypokinetic dysarthria
associated with Parkinson’s Disease and found it manifests differently between
individuals. Acoustic analysis has often been used to find correlates of perceptual
features for differential diagnosis. However, acoustic parameters that are robust for
differential diagnosis may not be sensitive to tracking speech changes. Previous
longitudinal studies have had limited sample sizes or variable lengths between data
collection. This study focused on using acoustic correlates of perceptual features to
identify acoustic markers able to track speech changes in people with Parkinson’s
Disease (PwPD) over six months. The thesis presents how this study has addressed
limitations of previous studies to make a novel contribution to current knowledge.
Speech data was collected from 63 PwPD and 47 control speakers using an online
podcast software at two time points, six months apart (T1 and T2). Recordings of a
standard reading passage, minimal pairs, sustained phonation, and spontaneous speech
were collected. Perceptual severity ratings were given by two speech and language
therapists for T1 and T2, and acoustic parameters of voice, articulation and prosody
were investigated. Two analyses were conducted: a) to identify which acoustic
parameters can track perceptual speech changes over time and b) to identify which
acoustic parameters can track changes in speech intelligibility over time. An additional
attempt was made to identify if these parameters showed group differences for
differential diagnosis between PwPD and control speakers at T1 and T2.
Results showed that specific acoustic parameters in voice quality, articulation and
prosody could differentiate between PwPD and controls, or detect speech changes
between T1 and T2, but not both factors. However, specific acoustic parameters within
articulation could detect significant group and speech change differences across T1 and
T2. The thesis discusses these results, their implications, and the potential for future
studies
Facilitating prosociality through technology: Design to promote digital volunteerism
Volunteerism covers many activities involving no financial rewards for volunteers but which contribute
to the common good. There is existing work in designing technology for volunteerism in HumanComputer Interaction (HCI) and related disciplines that focuses on motivation to improve
performance, but it does not account for volunteer wellbeing. Here, I investigate digital volunteerism
in three case studies with a focus on volunteer motivation, engagement, and wellbeing. My research
involved volunteers and others in the volunteering context to generate recommendations for a
volunteer-centric design for digital volunteerism. The thesis has three aims:
1. To investigate motivational aspects critical for enhancing digital volunteers’ experiences
2. To identify digital platform attributes linked to volunteer wellbeing
3. To create guidelines for effectively supporting volunteer engagement in digital volunteering
platforms
In the first case study I investigate the design of a chat widget for volunteers working in an
organisation with a view to develop a design that improves their workflow and wellbeing. The second
case study investigates the needs, motivations, and wellbeing of volunteers who help medical
students improve their medical communication skills. An initial mixed-methods study was followed by
an experiment comparing two design strategies to improve volunteer relatedness; an important
indicator of wellbeing. The third case study looks into volunteer needs, experiences, motivations, and
wellbeing with a focus on volunteer identity and meaning-making on a science-based research
platform. I then analyse my findings from these case studies using the lens of care ethics to derive
critical insights for design.
The key contributions of this thesis are design strategies and critical insights, and a volunteer-centric
design framework to enhance the motivation, wellbeing and engagement of digital volunteers

The face of nonbinary beauty communication on Instagram : a content analysis
Gender is a feature of beauty marketing, used in marketing segmentation and communication images, where binary images are predominant. Recently, the social identity of gender has become increasingly nuanced as a more complex set of identities, including genderqueer and nonbinary, influences marketing communications. As part of cultural expression, advertising reflects and impacts how consumers perceive themselves and others, with Generation Z consumers increasingly rejecting gender labels and stereotypes. Consequently, our study involves the visual meaning making of 222 Instagram images of beauty brands’ marketing communications with models other than “female” in traditional Western society’s conceptualization of gender. The findings reveal a group of models who are not female; while most of these images are genderqueer, a group that may be considered agender is evident. Both groups have distinctive although differing characteristics, suggesting the development of new stereotypes. This study contributes to understanding the changing representations of models: While beauty brands primarily use female models, the increased use of genderqueer and agender models can attract alternative target markets. It also highlights advertising’s place in cultural expressions that both reflect and impact how consumers perceive themselves and others.https://www.tandfonline.com/loi/ujci20hj2023Gordon Institute of Business Science (GIBS
Job Stress, Anxiety, and Depression in Mental Health Professionals: An Examination of Experienced Vicarious Trauma and Gender Differences
AbstractMental health professionals are susceptible to an increased risk of job stress, anxiety, and depression based on the very nature of their work. The study was quantitative, focusing on profile analysis. A two-way MANOVA was performed utilizing the independent variables of gender and vicarious trauma, and three dependent variables of job stress, anxiety, and depression. The population size was 88 mental health professionals with a Bachelor’s degree or higher who work in the behavioral health field, directly servicing clients in the capacity of supervision, case management, social work, counseling, or therapy. Participants completed four self-reported questionnaires: General Work Stress Scale (GWS), Beck Anxiety Inventory (BAI), Beck Depression Inventory-II (BDI-II), and the Trauma and Attachment Belief Scale (TABS). The results of the study indicated that there was no statistical significance of the interaction term of gender and vicarious trauma with respect to the GWS (F = 0.572, p = .45), BAI (F = 0.268, p = 0.60), or BDI-II (F = 1.270, p = .26). The results indicated there was no statistical significance in gender with respect to the GWS scale, BAI, or the BDI-II (F = 0.895, p = .347) (F = 2.870, p = 0.094) (F = 0.134, p = 0.715). In addition, the results did indicate there was a statistical significance in vicarious trauma with respect to the GWS (F = 9.79, p = 0.002), BAI (F = 18.98, p = 0.000), and BDI-II score (F = 38.2, p \u3c .01). The study outcomes may contribute to positive social change, assisting in the development, promotion, and facilitation of awareness training, educational workshops, organizational support systems, and gender-sensitive interventions for mental health professionals
