The ability to mentally travel in time is something we take for granted every day. In everyday life, we rarely or never reflect on how much remembering and how much imagining we experience in the course of a day, or on how our current thoughts and actions are shaped by past experiences and future goals. However, if this ability were damaged or even disappeared, as can happen in the case of dementia, for example, the question arises: who would we be without our memories and without our wishes, expectations, and goals? Therefore, thinking about mental time travel means thinking about an ability that defines us as human beings. However, Kant did not write much about memories and imagination, nor did he consider psychology to be a science. By referring to Kant's reconstructed theory of perception and using the transcendental philosophical theory of subjectivity (transzendentale Subjektivitätstheorie) as developed by Gerold Prauss (1990 ff.) allows us to incorporate Kant and Kantian vocabulary into a modern debate on mental time travel. Kant's theory of perception must first be extended to include the components of the past and the future. Strictly speaking, this addition is a further development of Kant's theory, as it acknowledges and incorporates empirical findings using Kantian vocabulary. The way in which we generate memories and imagination is basically the same. We need productive imagination (produktive Einbildungskraft) in both acts in order to achieve a time frame other than the present. We also need reproductive imagination (reproduktive Einbildungskraft) for both processes in order, to represent an object or event. Episodic remembering and imagination are about events in my past and future, not anyone else's. The decisive factor in my accepting of a memory or an imagination as my own is my consciousness. Based on a form of my self-awareness that is considered actual as well as the awareness that others (objects, events...) are actual (Selbst- / Fremdverwirklichungsbewusstsein, Friebe 2005) in the original perception, my remembering and imaging counts as a form of my self-awareness that can place itself and others in different times (Selbst- / Fremdverzeitlichungsbewusstsein). The latter can only be activated if there is any experience at all to which I can refer, from which I can derive something - whether as a memory or an imagination. Both acts are based on the subject's ability to reflect. This means that mental time travelling is initially only accessible to experienced individuals who consciously strive to perform these acts. However, memories are more prone to error. The possibilities for error described in this paper therefore also highlight the differences between remembering and imagining. These differences can provide new insights into the ongoing debate on mental time travel, which is currently dominated by two opposing theories: causal theories and simulation theories. The extended Kantian theory is a hybrid of the two.

Background: Guided mobile-based interventions may mitigate symptoms of anxiety disorders such as panic disorder, agoraphobia, or social anxiety disorder. With exposure therapy being efficacious in traditional treatments for these isorders, recent advancements have introduced 360° videos to deliver virtual reality exposure therapy (VRET) within mobile-based interventions. Objective: Despite ongoing trials evaluating the treatment’s efficacy, research examining patient perceptions of this innovative approach is still scarce. Therefore, this study aimed to explore patient opinions on specific treatment aspects of mobile-based interventions using mobile VRET and psychotherapeutic guidance for anxiety disorders. Methods: A total of 11 patients diagnosed with panic disorder, agoraphobia, or social anxiety disorder who had previously taken part in the experimental conditions of 2 randomized controlled trials for a mobile intervention including mobile VRET participated in cross-sectional, retrospective interviews. Using a semistructured interview format, patients were asked to reflect on their treatment experiences; personal changes; helpful and hindering aspects; their motivation levels; and their encounters with the mobile-based intervention, manualized treatment sessions, and the mobile VRET. Results: Thematic analysis led to the formation of 14 themes in four superordinate categories: (1) perceived treatment outcomes, (2) aspects of the mobile intervention, (3) experiences with mobile VRET, and (4) contextual considerations. Patients offered their insights into factors contributing to treatment success or failure, delineated perceived treatment outcomes, and highlighted favorable aspects of the treatment while pointing out shortcomings and suggesting potential enhancements. Most strikingly, while using a blended app-based intervention, patients highlighted the role of psychotherapeutic guidance as a central contributing factor to their symptom improvement. Conclusions: The findings of the thematic analysis and its diverse patient perspectives hold the potential to guide future research to improve mobile-based treatment options for anxiety disorders. Insights from these patient experiences can contribute to refining mobile-based interventions and optimizing the integration of VRET in accordance with patients’ preferences, needs, and expectations.

Due to the increase in online retail in recent decades, distribution centers in the supply chains of large e-commerce companies in particular are increasingly operating according to the “parts-to-picker” paradigm: storage bins (e.g., shelves) containing requested items are automatically transported to picking stations. This eliminates unproductive walking distances for warehouse employees, as is the case in conventional warehouses (“picker-to-parts”). Instead, workers remain at the stations to focus exclusively on picking and packing of customer orders. The storage bins are transported either by autonomous mobile robots (usually floor-bound vehicles) or the picking stations are directly connected to an automatic storage and retrieval system. To optimize picking in such a warehouse, incoming storage bins must be coordinated (i.e., synchronized) with outgoing customer orders at the picking stations in order to increase throughput and to reduce the load on the automatic storage and retrieval system. Depending on the (technical) equipment of the picking stations, the storage policy, and the composition of the customer orders, a number of slightly different synchronization problems arise. From an operations research perspective, these synchronization problems are characterized by the combination of elements of known combinatorial optimization problems: set covering, optimal order batching, and sequencing (of storage bins and orders). We analyze the computational complexity of various synchronization problems, develop and evaluate suitable exact and heuristic solution approaches for optimizing order picking (with a focus on application in robotic mobile fulfillment systems), and present business insights for practitioners.
