In experimental cognitive psychology, objects of inquiry are typically operationalized with psychological tasks. When interpreting results from such tasks, we focus primarily on behavioral measures such as reaction times and accuracy rather than experiences – i.e., phenomenology – associated with the task, and posit that the tasks elicit the desired cognitive phenomenon. Evaluating whether the tasks indeed elicit the desired phenomenon can be facilitated by understanding the experience during task performance. In this paper we explore the breadth of experiences that are elicited by and accompany task performance using in-depth phenomenological and qualitative methodology to gather subjective reports during the performance of a visuo-spatial change detection task. Thirty-one participants (18 females) were asked to remember either colors, orientations or positions of the presented stimuli and recall them after a short delay. Qualitative reports revealed rich experiential landscapes associated with the task-performance, suggesting a distinction between two broad classes of experience: phenomena at the front of consciousness and background feelings. The former includes cognitive strategies and aspects of metacognition, whereas the latter include more difficult-to-detect aspects of experience that comprise the overall sense of experience (e.g., bodily feelings, emotional atmosphere, mood). We focus primarily on the background feelings, since strategies of task-performance to a large extent map onto previously identified cognitive processes and discuss the methodological implications of our findings.
Polycystic ovary syndrome (PCOS) is an endocrine and metabolic disorder affecting women of reproductive age. Research has shown that epigenetic alterations such as DNA methylation may play a role in the development and progression of abnormal ovarian function and metabolic disorders in PCOS. Studies have identified specific genes (related with insulin signaling and steroid hormone metabolism) that are methylated in women with PCOS. DNA methylation appears to respond to various interventions aimed at altering health and lifestyle factors. We tested the efficacy of a mindfulness-based stress reduction program (MBSR) in PCOS patients. We examined its effects on anthropometric measurements, mental health and wellbeing, and alterations in DNA methylation in peripheral blood. MBSR was associated with a reduction in body mass index, waist circumference and blood glucose level, an improvement in subjectively perceived general health, emotional role limitation, and levels of pain, as well as mindfulness-like traits. MBSR reduced the expression of anxious symptomatology and subjectively perceived stress. Methylation changes were observed in four genes: COMT, FST, FKBP51, and MAOA. We conclude that MBSR may be a useful supplementary therapy to mitigate the deleterious effects of PCOS on mental health.
Microzonation for earthquake-induced liquefaction hazard is the subdivision of a territory at a municipal or submunicipal scale in areas characterized by the same probability of liquefaction manifestation for the occurrence of an earthquake of specified intensity.The liquefaction hazard at a site depends on the severity of expected ground shaking as well as on the susceptibility to liquefaction of that site. This in turn depends on geological, geomorphological, hydrogeological and geotechnical predisposing factors. Thus, liquefaction hazard implies the existence of territories characterized by a moderate to high level of intensity of expected ground shaking. Microzonation charts for ground shaking and liquefaction hazard play a key role for the mitigation of seismic risk of an urban centre as they provide a valuable tool for the implementation of prevention strategies and land use planning. The LIQUEFACT project fully addressed the problem of microzoning a territory for earthquake-induced liquefaction hazard in a specific work package. Four municipal testing areas were selected across Europe as peculiar case studies where to construct microzonation charts for earthquake-induced liquefaction hazard. They are located in Emilia-Romagna region (Italy), Lisbon metropolitan area (Portugal), Brežice territory (Slovenia) and Marmara region (Turkey). Their location was identified based on the following criteria: severity of expected seismic hazard, availability of geological and geotechnical data, presence of liquefiable soil deposits, documented cases of liquefaction manifestations occurred in historical earthquakes, representativeness of different geological settings, density of population in selected areas (exposure). This paper illustrates the general procedure developed in LIQUEFACT for the assessment of earthquake-induced liquefaction hazard at urban scale and presents the main achievements of the microzonation studies carried out at the four previously mentioned European testbeds. Since the microzonation studies have been carried out using a shared framework and methodology, this paper has the ambition to serve as technical guidelines for updating the standards and the operational criteria currently used in different countries worldwide to construct seismic microzonation maps of liquefaction hazard.

In cognitive science, it is unclear what precisely presence (both in the sense of objecthood and immersion) refers to in lived experience. The present study addresses the research question of what the relationship between presence is and lived space. A hundred and seventeen phenomenological interviews were conducted with 14 participants. We sampled their experience in a transdiagnostic manner. That is, we observed how the experience of presence changes both in circumstances appraised as positive (e.g., sexual intimacy) and negative (e.g., psychopathology). Our grounded theory suggests that presence is a phenomenon that is comprised of all available sensory knowledge, however, it itself is not present in any one sensory modality. Presence takes the form of a disembodied sense of solidity. Our findings can be related to the notion of transmodality in contemporary qualitative phenomenology (i.e., the idea that there are some aspects of experience that can be readily translated from one sensory modality to another. Further, how presence (in its capacity as immersion) is related to lived space can shed further light on the formation of delusions, suggesting that it is based on sensory alterations rather than changes in belief. Finally, the observation that presence as it appears in lived space need not perfectly correspond to the objective situation, can elucidate extant discussion on whether presence is an amodal aspect of consciousness.
This article proposes a method for consensually validating phenomenal data. Such a method is necessary due to underreporting of explicit validation procedures in empirical phenomenological literature. The article argues that descriptive sciencesexemplified by phenomenology and natural historyrely on nominalization for construction of intersubjectively accessible knowledge. To this effect, epistemologies of phenomenology and natural history are compared. The two epistemological frameworks differ in terms of their attitudes towards the interpretation of texts and visual epistemology, however, they both rely on eidetic intuition of experts for knowledge construction. In developing the method of consensual validation, I started out with the prismatic approach, a method for researching embodied social dynamics. I then used debriefings on the experience of consensual validation to further refine the method. The article suggests that for a nominalization of experiential world to be intersubjectively accessible, such a vocabulary must be independently constructed by the entire group of co-researchers. I therefore propose that during consensual validation, co-researchers be presented with composite descriptions of experiential categories, compare them with their experience, attempt to falsify them, and finally jointly name them. This approach does not yield a single vocabulary for description of experience, but several commensurable vocabularies, contingent on a specific research setting.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
