This thesis investigates three hypotheses in relation to the cognitive explanation of normal and problematic gambling behaviour. The "strong cognitive hypothesis" takes the view that if cognitive processes alone account for different levels of play, then the order of the events experienced during a task may be a good predictor of the levels of play. Four large scale experiments are presented focusing on the Illusion of Control, particularly the order effects originally observed by Langer and Roth (1975). Drawing on Hogarth and Einhom's (1992) belief adjustment model an adjusted methodology is employed making the paradigm resemble the real gambling decision making task more closely. The results of the Illusion of Control experiments suggest that the strong cognitive hypothesis can account for gambling in general, but there is no consistent support in favour of its role in explaining differential levels of play. Three questiormaire studies are then presented investigating the two alternative hypotheses assessed in this thesis. The "weak cognitive hypothesis" stipulates that an additional individual differences element is necessary to supplement the strong cognitive hypothesis in order to explain differential levels of gambling behaviour. Individual differences in the level of everyday general dissociation, the enjoyment and engagement in two forms of processing (Rational or Experiential, Epstein 1990), and in the extent to which heuristics and biases are used when making decisions are investigated. Factor analysis for the heuristics and biases investigation, particularly in relation to the understanding of the principle of randomness, reveals some evidence for the weak cogmtive hypothesis. Strongest evidence emerges in relation to the "integrative hypothesis" which stipulates that cognitive factors and processes are only important in relation to and interaction with other variables. The questioimaire studies investigate the role of erroneous beliefs and their relationship with the dissociation experienced within the gambling task. Using Structural Equation Modelling techniques, the results lead towards the generation of a new model of differential levels of gambling and the causal links between these variables and the loss of control are discussed.

Vocalizations are widely studied as possible non-invasive indicators of welfare. The most common vocalizations in pigs are grunts and screams. This thesis is focused on the relationship between vocal parameters of piglet's grunts and screams and the behavioural arousal (which is assumed to indicate stress intensity) during the social isolation.

The research programme had three principal objectives. First, the evaluation and extension of the extant conceptual framework pertaining to motivational music in exercise settings. Second, the development of a valid instrument for assessing the motivational qualities of music: The Brunel Music Rating Inventory-2 (BMRI-2). Third, to test the effects of motivational and oudeterous (lacking in both motivational and de-motivational qualities) music in an externally-valid setting. These objectives were addressed through 4 studies. First, a series of open-ended interviews were conducted with exercise leaders and participants (N = 13), in order to investigate the characteristics and effects of motivational music in the exercise setting. The data were content analysed to abstract thematic categories of response. These categories were subsequently evaluated in the context of relevant conceptual frameworks. Subsequently, a sample of 532 health-club members responded to a questionnaire that was designed to assess the perceived characteristics of motivational music. The responses were analysed across age groups, gender, frequency of attendance (low, medium, high), and time of attendance (morning, afternoon, evening). The BMRI-2 was developed in order to address psychometric weaknesses that were associated with its forbear, the BMRI. A refined item pool was created which yielded an 8-item instrument that was subjected to confirmatory factor analysis. A single-factor model demonstrated acceptable fit indices across three different pieces of music, two samples of exercise participants, and both sexes. The BMRI-2 was used to select 20 pieces of motivational music, which were delivered in a health club gymnasium. It was found that health club members (N = 112) exercised for longer under the condition of motivational music as opposed to oudeterous music (the club’s typical output); however, no differences were noted in terms of affective response.

Titel: Omedveten arousal i butiksmiljön. Nyckelord: Arousal, omedveten arousal, servicescape, butiksmiljö, konsumtionsbeteende, GSR-armband, eyetracking, elektrodermal aktivitet. Syfte: Syftet med denna studie är att undersöka vilka faktorer som framkallar omedveten arousal i en riktig butiksmiljö. Vidare vill vi undersöka om skillnader i kundrelaterade konsumtionsvariabler påverkar omedveten arousal. Metod: Studien kombinerar en kvantitativ och kvalitativ ansats där 60 respondenter deltog i studien. Data samlades in via två enkäter, GSR-armband och ett par eyetracking-glasögon. Bidrag: Studien har bidragit med en kategorisering av omedvetna arousalutslag baserat på vad respondenter reagerat på i butiken. Skillnader i kundrelaterade konsumtionsvariabler har identifierats i förhållande till omedveten arousal. Originalitet: Med hjälp av studiedesignen har data kunnat samlas in i en riktig butiksmiljö. Respondenterna har således kunnat handla som vanligt i en miljö med andra kunder, personal och fysiska faktorer i butiken. / Title: Unconscious arousal in a store environment. Key words: Arousal, unconscious arousal, servicescape, store environment, consumer behavior, GSR-wristband, eye tracking, electrodermal activity. Purpose: The purpose with this study is to examine what factors evoke unconscious arousal in a real store environment. We will also examine if there are any differences in customer related consumption variables which affect unconscious arousal. Method: The study combines a quantitative and a qualitative approach where 60 respondents participated in the study. Data was collected by two surveys, a GSR-wristband and a pair of eyetracking-glasses. Contributions: The study has contributed with a categorization of unconscious arousal peaks based on what the respondents reacted to in the store. Differences in customer related consumption variables have been identified in relation to unconscious arousal. Originality: The study design has allowed data to be collected in a real store environment. The respondents have been able to shop as usual in an environment with other customers, staff and physical factors in the store.
