In this study the role played by metaphor in psychotherapy is investigated. Issues discussed, included the formulation of a definition of metaphor as well as an adequate theory of metaphor. The place metaphor holds in thought and learning; as well as how it has found its expression within some psychotherapeutic traditions are also discussed. The primary aim of the dissertation is to illustrate the versatility of metaphor, enabling it to be a significant and powerful tool in the hand of the psychotherapist. The application of various forms of metaphor is illustrated through case studies which offer a discussion of how the specific type of metaphor had been applied in psychotherapy. In conclusion, some recommendations are made with regard to further research within the fields of psychotherapy and neuropsychology. / Psychology / M.A. (Clinical Psychology)

We present a statistical model of recreational trails, and a method to infer trail routes from geophysical data, namely aerial imagery and terrain elevation. We learn a set of textures (textons) that characterize the imagery, and use the textons to segment each image into super-pixels. We also model each texton's probability of generating trail pixels, and the direction of such trails. From terrain elevation, we model the magnitude and direction of terrain gradient on-trail and off-trail. These models lead to a likelihood function for image and elevation. Consistent with Bayesian reasoning, we combine the likelihood with a prior model of trail length and smoothness, yielding a posterior distribution for trails, given an image. We search for good values of this posterior using both a novel stochastic variation of Dijkstra's algorithm, and an MCMC-inspired sampler. Our experiments, on trail images and groundtruth collected in the western continental USA, show substantial improvement over those of the previous best trail-finding methods.

Recent research suggests that psychological techniques may facilitate injured athletes' rehabilitation, yet little is known about the psychological techniques trainers currently employ and how they view these interventions. In this study, 206 athletic trainers assigned Likert scale ratings to 11 psychological techniques indicating how much they valued a specific technique, how skillfully they employed it, and how often they utilized it. Trainers also responded to an open ended question asking how they would deal with the psychological aspects of an injury described in a short scenario. Results revealed a tentative model for the way trainers view psychological techniques. Categories of techniques included techniques involving the modification of physical and psychological states (goal setting, pain management, relaxation, imagery, and breathing techniques), techniques involving verbal cognitive techniques (communicating openly, changing negative self talk, emotional counseling, and crisis counseling), and non-recommended techniques (encouraging heroism and screening negative information). The study explored trainers' perceptions of each of the 11 psychological techniques in depth and discussed these findings. The study found that although trainers highly value psychological interventions in their work with injured athletes, they assigned low ratings to the techniques they knew little about. However, as exposure to sport psychology information increased, ratings assigned to the techniques that modify physical and psychological states also increased. Similarly, the longer trainers had worked in their field, the more highly they valued the verbal cognitive interventions. In contrast, neither exposure to sport psychology information or athletic training experience proved predictive of ratings assigned to the non-recommended psychological techniques. These findings suggest the importance of introducing skills training for psychological techniques early in the athletic trainers' educational curriculum so that trainers can gain awareness of the efficacy of certain psychological techniques and skill at using these techniques. Moreover, trainers could benefit from course work explaining potential negative consequences of employing harmful or ineffectual psychological interventions.

Implementation intentions have been shown to improve prospective memory performance among a variety of populations. In two studies, the effectiveness of implementation intentions was examined among young and older adults. In Experiment 1 64 young adults were placed into one of four instructional conditions (Read-Only, Imagery, Implementation Intention, Combined) before completing a laboratory-based prospective memory task. Results reveal that prospective memory performance improves under each of the three experimental conditions, but that there is no additional benefit of combining imagery with implementation intentions. In a novel finding, imagery alone produced improvements comparable to implementation intentions. Experiment 2 investigated the effect of implementation intentions among 32 older adults, who were characterized as possessing high- or low-frontal function based on neuropsychological test performance. Implementation intentions improved prospective memory among both groups, regardless of frontal function. The results of these studies suggest that implementation intentions can improve prospective memory among both young and older adults. Importantly, these findings reveal that imagery alone may be an effective means of improving prospective memory. Additionally, that implementation intentions improved prospective memory among older adults, regardless of frontal function, raises important questions about potential mechanisms underlying the effectiveness of implementation intentions.

Abstract The act of knowing is a critical determinant of what is known, yet there are limits and potential violence inherent in all ways of knowing. Social workers have an ethical responsibility to understand our means of knowing and our knowledge claims – both shape the work we do. Conspicuously under-represented as creators of/commentators on how they are represented, people with intellectual disabilities have had little/no control over what or how they are known. These ethical and epistemological concerns were the focus of this arts-informed qualitative study. The purpose was an interrogative encounter with one way of knowing – how public photographic imagery of people with intellectual disabilities influences knowledge about them. It was concerned, however, to come to this knowledge through an inquiry into how labelled people would, themselves, interpret and respond to these representations, and how they might use photography to trouble disabling images and non-disabled (social work) knowing. Theoretically framed by a critical disability lens, the work was influenced, too, by Derrida’s essay on photography, “The Right of Inspection”. The other regarding aspect of the philosophy of Emmanuel Levinas, his concern with our ethical responsibility to the alterity of the Other, most powerfully informs the work. Four adults with intellectual disabilities accepted the invitation to participate in this project. First, they critically engaged with a selection of public photographic images. In a unique methodological turn, they then transformed the images to reflect their critique. Interpretive analysis of the critiques and transformations identified four thematic ideas. Participants’ critiques were insightful and profound; transformations provocative and disruptive. Challenging dominant assumptions – and demanding non-disabled others re-think intellectual disability and people so labeled – the critiques and transformations also respond to the social/political/ideological/psychological ramifications of photographic imagery on the lived experience of intellectual disability. Through the work, participants confront non-disabled responses to public photographs and to labeled people, challenging non-disabled others to question their knowledge, attitudes, and behaviours. The work also raises questions about research and people with intellectual disabilities: the possibilities for voice and empowerment through inclusive research strategies and visual methodologies, and the transformative potential of dialogic encounters between people with and without intellectual disabilities.

Communicating climate change and other long-term environmental issues to the wider public is a challenging process involving many barriers to action. Visualisations have the ability to overcome these barriers. Furthermore, the benefits of visual images over verbal information have been supported. However, there is a lack of research on how visual images can motivate behaviour. Based on Elaborated Intrusion theory, it is proposed that visual images can be internalised as mental images which can act as a ‘motivational bridge’ for pro-environmental behaviour. Six studies exposed participants to visual pro-environmental messages. Throughout all studies images were internalised as mental images, associated with intrusive thoughts. Consistently, mental images were strongly associated with pro-environmental goals and behaviour change (self-report and actual). Also, interfering with visual mental imagery, using cognitive tasks, reduced self-reported behaviour change (Study 6). Overall, two motivational roles of mental imagery emerged: mental images can trigger pro-environmental goals and can strengthen the relationship between pro-environmental goals and behaviour. The development, strength, and vividness of mental imagery depended on interacting individual and message characteristics. A vivid message was more effective when the message topic was relevant to the target individual (Study 2). Also, a message in line with existing values evoked more vivid mental imagery (Studies 2 to 6). A message could activate specific values as well if mental imagery was not interfered with (Study 5 and 6). And finally, positive and negative images were associated with different feelings, but could both be internalised and motivate behaviour (Study 3 and 6). A combined message could overcome the negative feelings associated with a fear appeal (Study 6). This thesis developed a theoretical framework, integrating approaches from social and cognitive psychology, which can help explain and predict responses to visual environmental messages. Six studies showed that the effect of a visual image on behaviour depends, among other factors, on its ability to trigger recurring mental imagery. Insights provide opportunities for designing evidence based visual pro-environmental messages. In turn this can maximise the impact visual messages have on changing people’s pro-environmental behaviour.

The overarching aim of this thesis was to contribute towards the translation of a laboratory paradigm into a clinical intervention: that is, to develop a positive Cognitive Bias Modification (CBM) technique using mental imagery into an internet-based computerized intervention for people with clinical depression. Preliminary studies using an imagery-based CBM to modify interpretation bias in depression have shown significant effects of the CBM in alleviating depressive symptoms. We know very little, however, about the mechanisms underlying the beneficial effect of imagery-based CBM in depression. A particular focus of the current thesis was to explore the effects of imagery-based CBM on variables that were thought to contribute to symptom improvement: mental imagery, emotion and behaviour. Experiment 1 explored these effects in a sample of mildly depressed individuals, using a CBM paradigm in which participants were required to generate mental imagery in response to positive, negative or mixed (control) combinations of picture and word cues. Participants assigned to the positive imagery condition showed mood improvements as well as enhanced behavioural performance (fishing game task) and reduced cognitive bias compared to participants in the two other conditions. Further, positive imagery was rated as increasingly vivid as they went along with the training. Study 2 explored the possibility that the behavioural task (i.e. a fishing game) used in mildly depressed individuals to detect CBM-induced differences in behaviour could be associated with behavioural differences between individuals with various and clinical levels of depressive symptoms. The hypothesis was tested that in a sample of individuals with minimal to severe symptoms of depression, behavioural performance on the fishing game would be inversely related to the severity of their depressive symptoms. As predicted, participants with higher depression scores performed less well on the fishing game task than those with lower scores, and this association remained when controlling for other variables such as state mood. Experiment 3a and 3b constituted the first two pilot studies exploring the feasibility of delivering imagery-based CBM over the internet to individuals with clinical depression. In Experiment 3a, the imagery-based CBM was developed into an internet-based intervention involving 6 sessions of CBM that participants completed in their own home over a week. The Oxford Imagery Generation (OxIGen) program was piloted in a small sample (N = 6) of clinically depressed individuals, and qualitative data were collected to assess experience of the intervention. As a result, refinements were made to improve the intervention and enhance engagement. In Experiment 3b, the finalised version of the OxIGen program, which involved 12 sessions of online CBM completed over a month, was piloted in a small sample (N = 8) of individuals with clinical depression. Results showed high levels of acceptability and adherence. Three of the four participants allocated to the positive imagery version of OxIGen showed reliable levels of symptom improvement. The exploration of the effects of OxIGen on mental imagery, bias and behaviour provided a mixed picture. For example, the predicted change in vividness for positive future imagery and negative interpretative bias was only found in two of the four participants from the positive imagery group. Finally in Experiment 4, the effects of OxIGen on positive future imagery and behaviour were examined as part of a wider clinical trial involving a large sample (N = 150) of individuals with clinical depression. The larger scale of this study allowed a sufficiently powered test of the prediction that the intervention would lead to changes in specific features of imagery (i.e. vividness and likelihood of positive future imagery) and increases in behavioural activation. Further, the hypothesised link between positive future imagery and optimism was tested. The results examined whether the OxIGen intervention can induce changes at different levels of psychological functioning (i.e. emotional, cognitive and behavioural). It is discussed that the combined action of these changes may reinstate a positive feedback cycle that ultimately leads to symptom improvements. Existing resources are largely insufficient to combat the major health problem of depression. The development of a promising laboratory paradigm towards a clinical intervention is an important step towards the development of short and inexpensive forms of treatment that can be delivered to the hands of the many people who need help.

The influence of Vonnegut’s didactic purpose of writing on the treatment of theme  and structure in Slaughterhouse-Five is investigated in this study. The following  elements of structure are studied: point of view, the treatment of time, characterization,  the use of other sources, and imagery. These are constantly related to  the novel’s themes, such as war, cruelty, death, time, innocence, survival, free  will, fantasy and regeneration. Since Vonnegut himself survived the Dresden  bombings during World War Two, his novel is very personal, which is particularly  reflected in his point-of-view technique, the subject of Chapter One. Vonnegut creates  double narrators in Slaughterhouse-Five : a personal one, including authorial  intrusions, and an impersonal one. This division is a direct reflection of the  dichotomy between reality and fantasy that prevails in the novel.  In Chapter Two, Vonnegut’s treatment of time is demonstrated to be a process of  spatialization. Structurally, this means a fragmented narrative split into several  time levels that chiefly form what the author calls his ”telegraphic schizophrenic"  style. Thematically, the protagonist comes "unstuck" in time, thus succeeding in  confronting an absurd world and finally transcending death.  Vonnegut uses the depiction of character mainly to express ideas and to reinforce  themes, since he regards his characters as "bugs in amber," involuntarily stuck,  excepting their capacity for fantasy. To facilitate the reader’s recognition of  these sketchy characters, Vonnegut has equipped them with marks of recognition,  often repeated, and names that provide clues to their personalities. All characters  are shown to be isolated and lonely, except on Tralfamadore where a dream woi;ld  exists.  In the fourth chapter, Vonnegut’s use of other sources is examined. His carefully  chosen quotations fall into two groups: first, historical sources that verify facts,  such as the Dresden catastrophy; second, fictional sources that stimulate the human  imagination, which turns out to be the protagonist's means of survival.  Finally, imagery in Slaughterhouse-Five, studied in Chapter Five, is found to be  used for enrichment of a style otherwise characterized by great economy. Much of  the imagery strikes a humorous tone. A simple, quotidian vocabulary is developed.  War imagery is used to deglorify war. Animal imagery is invoked to ridicule and to  show man’s true place in the universe. Several oxymora further reinforce the incongruity  prevailing in the Vonnegutian world. The negative effect of imagery is  also found in symbols pertaining to Billy’s life situation. As a contrast, however,  there are also positive symbols emphasizing nature’s annual cycle of rebirth signifying  hope and regeneration.  Many of the stylistic elements studied reveal that Vonnegut has chosen thematic and  structural solutions that make his novel accessible to a large reading audience.  The fragmented, at times circular, structure of Slaughterhouse-Five is indeed a  "dance with death." In a thematic sense, death is the writer’s own muse that he  must dutifully dance with in order to create his work of art. Slaughterhouse-Five  is not only Vonnegut’s account of his own war experience but also a statement on  the human condition. / digitalisering@umu

The purpose of the study was to determine the effect on student performance and attitude toward high school Latin by Latin I students when provided with vocabulary instruction through chunking and imagery.

A skill instruction technique based on cognitive behavioral principles was applied to thermal imagery to determine if it could enhance either subjective or physiological responsiveness. The effects of imagery instruction were compared with the effects of muscle relaxation on imagery vividness, thermal imagery involvement, and the finger temperature response. The subjects were 39 male and 29 female volunteers from a minimum security federal prison. The personality characteristic of absorption was used as a classification variable to control for individual differences. It was hypothesized that high absorption individuals would reveal higher levels of imagery vividness, involvement, and finger temperature change; that imagery skill instruction and muscle relaxation would be more effective than a control condition; and that the low absorption group would derive the greatest benefit from the imagery task instruction condition. None of the hypotheses was supported. Finger temperature increased over time during the experimental procedure but remained stable during thermal imagery. The results suggest that nonspecific relaxation effects may best account for finger temperature increases during thermal imagery. Results were discussed in relation to cognitive-behavioral theory and the characteristic of absorption.
