A realist approach to thematic analysis: making sense of qualitative data through experiential, inferential and dispositional themes
2021
Thematic analysis (TA) is the most widely used method for analysing qualitative data. Recent debates, highlighting the binary distinctions between reflexive TA grounded within the qualitative parad...
How Long Did You Look At Me? The Influence of Gaze Direction on Perceived Duration and Temporal Sensitivity.
2016
Faces that exhibit emotionally negative expressions in mutual gaze have been shown to induce a dilation of perceived duration. The influence of gaze by itself on duration judgments, however, has rarely been investigated. We argue for a social interaction hypothesis, according to which humans should be highly accurate and precise (sensitive) when processing the temporal dynamics of mutual gaze. In three experiments, we investigated whether the direction of observed gaze affects perceived duration and temporal sensitivity. In Experiment 1, subjects did indeed estimate the duration of direct gaze more accurately as compared to the duration of averted gaze. In Experiments 2 and 3, subjects had…
Methodological Approach for Identifying Mechanisms in ICT4D: A Critical Realism Perspective
2017
Part 4: Social Mechanisms of ICT-Enabled Development; International audience; The ontological questions ‘What is ICT?’ and ‘What is development?’ are described and documented in literature. Similarly, methodological approaches for understanding how ICT leads to development or for measuring the impact of ICT are described. However, explaining ‘why’ ICT works or not in the contexts of developing countries needs further investigation. We propose a critical realism based methodological approach for answering the above mentioned ‘why’-question. The core of a critical realism based approach is to identify the underlying mechanism(s) that may explain a phenomenon of why ICT leads to development. W…
Sensory and affective components of symptom perception: A psychometric approach
2018
Psychological accounts of symptom perception put forward that symptom experiences consist of sensory-perceptual and affective-motivational components. This division is also suggested by psychometric studies investigating the latent structure of symptom reporting. To corroborate the view that the general and symptom-specific factors of a bifactor model represent affective and sensory components, respectively, we performed bifactor models applying confirmatory factor analytic approaches to the Patient Health Questionnaire-15 and the Checklist for Symptoms in Daily Life completed by 1053 undergraduate students. Additionally, we explored the association of latent factors with negative affectivi…
Somatic Symptom Perception and Interoception
2020
Abstract. Models of chronic somatic symptoms assume that abnormalities in interoception are related to the development and maintenance of symptom distress. Different models, however, disagree on the exact nature of the assumed abnormality: cognitive-behavioral models stress a hypervigilant cognitive style (predicting higher interoceptive accuracy) whereas predictive processing models assume a less detailed sensory processing (predicting lower interoceptive accuracy). This study aimed at testing the relationship between interoception and symptom perception. Using structural equation modeling, associations between cardiac interoception and symptom perception were tested in a sample of studen…

The Body Image Questionnaire-20 (FKB-20) is one of the most applied self-report measures in the context of body image assessment in German-speaking regions. A version of the FKB-20 capturing an ideal concept of body image is also available. A special property of the scale is its high sensitivity for individuals suffering from anorexia nervosa. The present research provided a short version of this scale (for both variants) and examined its validity in a representative sample (N= 2,347) of the German population. We utilized factor analysis methods to identify the optimal short scale of the measure, finding excellent model fit and reliability for a two-factor model (FKB-6) for both real and id…
What represents a face? A computational approach for the integration of physiological and psychological data.
1997
Empirical studies of face recognition suggest that faces might be stored in memory by means of a few canonical representations. The nature of these canonical representations is, however, unclear. Although psychological data show a three-quarter-view advantage, physiological studies suggest profile and frontal views are stored in memory. A computational approach to reconcile these findings is proposed. The pattern of results obtained when different views, or combinations of views, are used as the internal representation of a two-stage identification network consisting of an autoassociative memory followed by a radial-basis-function network are compared. Results show that (i) a frontal and a…

Les deux faces – objective/subjective – de la mobilité sociale
2006
06062; National audience; How does objective social mobility, traditionally measured with tables of mobility drawn up by sociologists, relate to feelings about mobility, i.e., how individuals perceive, explain and appraise their social trajectory? Using a question from a survey (Insee's Formation, qualification professionnelle), subjective mobility was statistically evaluated so as to bring the two approaches to mobility together and measure the (considerable) frequency of deviations. Subjective mobility was then analyzed qualitatively on the basis of interviews conducted with respondents in the same survey. This helps us account for deviations and identify the bundle of parameters that peo…
Rakstīšanas traucējumu mazināšana 1.klases skolēniem ar nepietiekami attīstītu fonemātisko uztveri
2018
Darba tēma: Rakstīšanas traucējumu mazināšana 1.klases skolēniem ar nepietiekami attīstītu fonemātisko uztveri. Diplomdarba mērķis ir teorētiski izzināt par fonemātisko uztveri, tās traucējumiem un to novēršanu un praktiski pētīt teorijā gūtās atziņas. Tādējādi iegūts priekšstats par pētāmo problēmu. Darba pirmajā daļā ir analizēta rakstīšanas traucējumu teorētiskais aspekts, pētot gan rašanās cēloņus, iemeslus, iedalījumu, rakstīšanas iemaņu pārbaude, kā arī konkrētais vecumposms problēmas sakarā. Otrajā daļā tiek veikts praktiskais pētījums par rakstīšanas traucējumiem X skolas 1. klasē. Tas ir veikts 4 posmos: sākotnējā pārbaude, koriģējošā darbība, atkārtota pārbaude un rezultātu analīz…
