Despite the recent popularity of the concept of emotional intelligence, several researchers question current emotional intelligence tests on several grounds including their lack of construct validity and unstable factor structure. This thesis aims to investigate the construct validity of emotional intelligence. In particular, the present study seeks to (1) confirm the factorial validity of emotional intelligence, (2) examine the convergent validity between a performance-based test and self-report measure of emotional intelligence, (3) investigate the convergent validity between emotional intelligence and cognitive intelligence, (4) confirm the place of emotional intelligence in the “general cognitive intelligence” taxonomy, (5) measure the discriminant validity of emotional intelligence when correlated with personality traits, and finally, (6 and 7) assess the incremental validity of emotional intelligence, as measured by a performance-based test, over cognitive intelligence, personality traits, a self-report measure of emotional intelligence, and trait emotional intelligence in predicting [6] leadership practices and [7] positive interpersonal relationships. To achieve these aims, a conceptual framework is developed in line with the concept of ability-based emotional intelligence. As the present study is quantitative in nature, statistical tools such as Rasch measurement model, Structural Equation Modelling and SPSS are employed to test the proposed hypotheses. Data were collected from 710 undergraduate students registered at a public Malaysian University. The findings revealed that: (1) the four-factor structure of ability-based emotional intelligence construct can be deemed construct valid, (2) there is no convergent validity between performance-based and self-report measure of emotional intelligence (3) there is no convergent validity between emotional intelligence and cognitive intelligence, (4) ability-based emotional intelligence has no place in the intelligence taxonomy, (5) there is a discriminant validity between emotional intelligence and personality, and finally, (6 and 7) emotional intelligence (performance-based measure) exhibits incremental validity in predicting [6] the leadership practices and [7] the positive interpersonal relationships, while controlling for personality traits, self-reported emotional intelligence, and trait emotional intelligence. The implications of these findings are synthesized in terms of the existing literature and the prevailing conceptual framework set out at the beginning of this research, which could shape the direction for future research on the emotional intelligence construct.

Objectives: (1) To ascertain whether adult siblings of disabled individuals are more prone to anxiety and depression symptomatology than a closely matched control group. (2) To examine the contribution that perceived parenting styles, attachment styles and personality traits play in the long-term affective outcome of these siblings. (3) To consider if the type of disability has a role in sibling affective outcome. Design: A cross-sectional, closely matched study design, with data collected through self-report. One-way ANOVAs, correlational analyses, moderation and mediation analyses were applied. Participants: Adult siblings of disabled individuals (SDI), were initially contacted through support groups, such as SIBS, the Down’s Syndrome Association, the National Autistic Society and the Prader-Willi Association (UK) and responded to a postal or e-mailed questionnaire; 150 participants returned the completed questionnaire. The 150 control group participants were closely matched on the variables of gender, age, marital status and when possible socio-economic status, in order to compare like with like. This group was contacted through friends, family, work colleagues and local businesses. Measures: All the participants completed a range of demographic questions; the SDI were additionally asked questions regarding their disabled sibling. The established measures used included the Hospital and Anxiety Depression Scale (Zigmond & Snaith, 1983), Experiences in Close Relationships (Brennan, Clark & Shaver, 1998), an adapted measure of the Descriptions of Parental Caregiving Style (DPCS, Hazan & Shaver, 1986) and the International Personality Item Pool (Goldberg, 1999). Results: The majority of SDI reported no increased anxiety or depression symptomatology, however, when compared the SDI did report higher levels of anxiety and depression symptomatology than the control group; also higher levels of perceived inconsistent mothering, attachment-related anxiety and neuroticism, with lower levels of extraversion than the control group. These variables mediated the path between having a disabled sibling and anxiety and depression, with the notable exception of perceived inconsistent mothering. This variable showed no association with any of the established measures for the SDI group; however, there were associations consistent with previous research for the control group. There was no moderation effect on anxiety or depression between the demographic variables and SDI. The autistic spectrum disorder siblings reported similar levels of anxiety symptomatology to Prader-Willi siblings but higher than Down’s syndrome siblings and the control group and they also reported the highest levels of depression symptomatology. Conclusions: The adult SDI’s higher propensity towards anxiety and depression is a cause for concern; particularly when explained through heightened levels of attachment-related anxiety, high levels of neuroticism and low levels of extraversion. The lack of association with perceived inconsistent mothering requires further investigation. These results can help guide interventions or clinical therapies; the emotional well-being of SDI is paramount as they will possibly be among the first group to assume responsibility for their disabled siblings.

Theories of how individuals reason, and how they experience emotion abound in the psychological literature; yet, despite the common lay-theories of how emotions might affect a person’s reasoning, very little empirical work has been conducted on this relationship. The current thesis addresses this knowledge-gap by first distilling from the literature two classes of emotion theory; Information, and Load; and then systematically testing the explanatory power of these theories. A dual-process framework is employed in order to define low (Type One) and high effort (Type Two) strategies. Information theories predict that negative emotion cues more analytic processing relative to positive emotion, whereas load theories predict both positive and negative emotion to suppress use of high-effort strategies. Thus the two theories are compared by varying incidental and integral emotion across syllogistic reasoning, conditional reasoning, and the ratio-bias task, and assessing the engagement of Type One and Type Two processes across positive emotion, negative emotion, and control conditions. The findings suggest that emotion effects in syllogistic reasoning do not consistently support either Load or Information theories (Experiments 1-4). Emotion effects are found to be typically larger for integral than incidental emotion (Experiment 5), and most frequently serve as Information in verbal (Experiments 6 and 7) and visual conditional reasoning tasks (Experiment 8). Furthermore, these effects are to a large extent dependent on task properties such as the number of alternative antecedents (Experiments 9 and 10), and are greater on more difficult tasks (Experiments 11 and 12). These findings suggest that emotion has a greater impact on Type Two than Type One processes. A range of methodological and theoretical implications which will inform future work in this area are also discussed in the closing chapter.

I argue that emotion is an ontologically emergent and sui generis. I argue that emotion meets both of two individually necessary and jointly sufficient conditions for ontological emergence. These are, (i) that emotion necessarily has constituent parts to which it cannot be reduced, and (ii) that emotion has a causal effect on its constituent parts (i.e. emotion demonstrates downward causation). I argue that emotion is partly cognitive, partly constituted by feelings and partly perceptual. 1) I argue that both the type and the intensity of an emotion supervene on cognitive factors. But emotion cannot be reduced to cognition because emotions are paradigmatically valenced and cognitions are not. 2) I argue that the phenomenal properties of emotion are determined by bodily feelings, thus emotion necessarily requires feelings. But emotion cannot be reduced to feelings because emotion has rational properties not held by bodily feelings. 3) I argue that the intentional objects of emotion are perceptual objects, and hence emotion necessarily requires perception. But emotion cannot be reduced to perception because emotion has second orders (as evidenced by metaemotion) and perception does not. Thus emotion meets the first necessary condition for ontological emergence; emotion has constituent parts to which it cannot be reduced. I go on to argue that emotion has a causal effect on its 4) cognitive, 5) feeling, and 6) perceptual parts, both as a faculty and at the level of the individual emotion. Emotion meets the two individually necessary and jointly sufficient conditions for ontological emergence: (i) emotion has composite parts to which it cannot be reduced, and (ii) emotion has a causal effect on its composite parts. Thus emotion is ontologically emergent. Being ontologically emergent, emotion is sui generis.

Most of the social cognitive and affective neuroscience in the past 3 decades has focussed on the face. By contrast, the understanding of processing social cues from the body and voice have been somewhat neglected in the literature. One could argue that, from an evolutionary point of view, body recognition (and particularly emotional body perception) is more important than that of the face. It may be beneficial for survival to be able to predict another’s behaviour or emotional state from a distance, without having to rely on facial expressions. If there are relatively few cognitive and affective neuroscience studies of body and voice perception, there are even fewer on the development of these processes. In this thesis, we set out to explore the behavioural and functional developmental trajectories of body and voice processing in children, adolescents and adults using fMRI, behavioural measures, and a wide range of univariate and multivariate analytical techniques. We found, using simultaneously recorded point-light and full-light displays of affective body movements, an increase in emotion recognition ability until 8.5 years old, followed by a slower rate of accuracy improvement through adolescence into adulthood (Chapter 2). Using fMRI we show, for the first time, that the body-selective areas of the visual cortex are not yet ‘adult-like’ in children (Chapter 3). We go on to show in Chapter 4, that although the body- selective regions are still maturing in the second decade of life, there is no difference between children, adolescents and adults in the amount of emotion modulation that these regions exhibit when presented with happy or angry bodies. We also show a positive correlation between amygdala activation and amount of emotion modulation of the body-selective areas in all subjects except the adolescents. Finally, we turn our attention to the development of the voice- selective areas in the temporal cortex, finding that, contrary to face and body processing, these areas are already ‘adult-like’ in children in terms of strength and extent of activation (Chapter 5). These results are discussed in relation to current developmental literature, limitations are considered, direction for future research is given and the wider clinical application of this work is explored.

At a perceptual level, faces and voices consist of very different sensory inputs and therefore, information processing from one modality can be independent of information processing from another modality (Adolphs & Tranel, 1999). However, there may also be a shared neural emotion network that processes stimuli independent of modality (Peelen, Atkinson, & Vuilleumier, 2010) or emotions may be processed on a more abstract cognitive level, based on meaning rather than on perceptual signals. This thesis therefore aimed to examine emotion recognition across two separate modalities in a within-subject design, including a cognitive Chapter 1 with 45 British adults, a developmental Chapter 2 with 54 British children as well as a cross-cultural Chapter 3 with 98 German and British children, and 78 German and British adults. Intensity ratings as well as choice reaction times and correlations of confusion analyses of emotions across modalities were analysed throughout. Further, an ERP Chapter investigated the time-course of emotion recognition across two modalities. Highly correlated rating profiles of emotions in faces and voices were found which suggests a similarity in emotion recognition across modalities. Emotion recognition in primary-school children improved with age for both modalities although young children relied mainly on faces. British as well as German participants showed comparable patterns for rating basic emotions, but subtle differences were also noted and Germans perceived emotions as less intense than British. Overall, behavioural results reported in the present thesis are consistent with the idea of a general, more abstract level of emotion processing which may act independently of modality. This could be based, for example, on a shared emotion brain network or some more general, higher-level cognitive processes which are activated across a range of modalities. Although emotion recognition abilities are already evident during childhood, this thesis argued for a contribution of ‘nurture’ to emotion mechanisms as recognition was influenced by external factors such as development and culture.

The aim of this study is to explore the emotion of disappointment in organisations and to develop a new line of theorising inspired by psychodynamic theory. The current literature casts disappointment as a negative emotion undermining morale, depressing expectations and justifying inaction and inertia. This only captures part of the complexity of disappointment and leaves unexplored both its impact on the organisation and its potential creativity. The study presents a theoretical framework derived from research that depicts disappointment as unfolding in three positions; I am disappointing, I am disappointed and I disappoint. It asserts the importance of disappointment as an integrative emotion. The study identifies a contradiction: that at the same time as being seen as ‘of little concern’ to individuals, there is fear within organisations that disappointment will undermine stability and destroy positive feelings. The study shows how disappointment is connected to, and may help to transform, the dynamics of blame in organisations. Such transformation can be based on an ability to integrate failure and on a development of the relationship between disappointment and learning. Disappointment represents the loss of the fantasy of stability. When reconceptualised in this way, disappointment results in a reimagining of possibility. Fantasy and reality are brought into conscious awareness and tolerated rather than extruded. The imaginary ideal organisation can be seen for what it is: a fantasy that can never be realised. The imaginary ideal is mourned and replaced by a more realistic entity. Organisation members’ previous efforts to organise disappointment through blame, shame and extrusion is now recognised as a disappointing strategy. Understood thus, disappointment is at the very heart of organising as it invites consideration of the relationship between fantasy and reality. This differentiates it from other types of social defences which, by their nature defend against thinking and learning.

Empathy is a central concern in the counselling process. Though much researched, and broadly commented upon, empathy is still largely understood through the words within a client-counsellor interaction. This semantic focus continues despite converging lines of evidence that suggest other elements of an interaction – for example body language – may be involved in the communication of empathy. In this thesis, the foundations of empathy are examined, focusing on empathy’s professional instantiation. These foundations are then related to the idea that the face, and its ability to express emotion, are an important part of the empathic process. What follows is an experiment testing 60 participants. This was a between groups design, with participants assigned to two even groups; one group receiving training in how emotion appears on the face: using the training program eMETT; the other reading a passage on empathy. Following the intervention, hypothesised group differences were assessed using the following analyses. Firstly, an Independent sample T-test, compared group means on the Ickes Empathic Accuracy paradigm, the measure of empathy used. Secondly, a further Independent sample T-test assessed the effect of eMETT training. Thirdly, an ANCOVA, evaluated whether the obtained results may have been confounded by age difference between the experimental groups. Finally a correlational analyse tested for any relationship between baseline and outcome measures. The hypothesis tested stated: training in facial expressions of emotion will enhance counsellors’ empathic accuracy; a hypothesis for which positive evidence was shown. The implications of this evidence suggest efficacy of the eMETT training to enhance empathic accuracy, though this is qualified through critical examination of the experimental method. Suggestions for refinement of this method are discussed.

This thesis comprises three chapters exploring health professionals’ experiences and attitudes regarding diagnoses that challenge mental health services. The first chapter is a systematic literature review investigating the impact of training on staff attitudes towards personality disorder. Eleven articles were reviewed and critically evaluated. Despite inconsistencies in the data and a number of methodological concerns, there is evidence to suggest that training is effective in improving staff members’ cognitive and affective attitudes towards personality disorder, and their therapeutic engagement with service users. Clinical and research implications are discussed in relation to developing staff training packages regarding personality disorder. The second chapter is a qualitative study of mental health nurses’ experiences of caring for adults with autism spectrum disorder (ASD) in acute inpatient services. Semi-structured interviews were conducted with seven nurses and the transcripts were analysed using Interpretative Phenomenological Analysis. The two major themes that emerged from the data indicated that nurses felt confused and unable to make sense of autistic presentations, but were able to overcome these challenges by focusing on their core nursing values and providing person-centred care. Overall, the findings highlight mental health nurses’ lack of knowledge about ASD. Clinical implications are discussed in relation to developing staff members’ skills and confidence in working with this client group. In the third chapter, personal reflections on the research process are discussed, with a particular focus on stigma and stereotyping in mental health services. These include the evolution of my own perspective and a consideration of the role of clinical psychologists in supporting staff.

This thesis explores the role of mood in adherence to changes in behaviour required for weight maintenance following weight loss in an obese sample. Significant increases in physical activity are necessary for successful weight maintenance, yet this change in lifestyle remains challenging for many. Anecdotally, the importance of being in the 'right mood' to make lifestyle changes is frequently reported. A systematic review of the weight maintenance literature revealed that a number of behaviour change techniques were associated with effective weight maintenance interventions. Therefore, the current randomised control study employed relevant behaviour change techniques within two goal setting interventions to improve either daily steps walked or mood compared to a control group in a weight loss programme cohort. The number of daily steps walked and mood were evaluated and the following questions were addressed: 1) In an obese population enrolled in a weight loss programme, do goal-setting interventions increase the number of steps walked compared to those in a control group? 2) Does the mood score differ for those participants in the mood improvement intervention group compared to those in the steps-walked intervention or control groups? 3) Does weight change differ for those individuals who have shown mood improvement compared to those whose mood is unchanged/worsened? The primary outcomes of steps walked, mood and weight were recorded immediately after intervention and again after unsupervised follow up 6-months later. The results showed that all groups increased the number of steps walked but not significantly so. This increase was greatest for the steps-walked group during the active intervention period but greatest for the mood intervention group during the unsupervised follow-up period. Mood improved significantly for all groups and was associated with significantly increased weight loss at follow-up. A trend for increased steps walked being associated with improved mood was observed in the 6-month follow up period. These findings highlight the links between mood and continued participation in lifestyle behaviour changes required for weight maintenance. Future research priorities are outlined for this field.
