    For efficient navigational search, humans require full physical movement but not a rich visual scene

    During navigation, humans combine visual information from their surroundings with body-based information from the translational and rotational components of movement. Theories of navigation focus on the role of visual and rotational body-based information, even though experimental evidence shows they are not sufficient for complex spatial tasks. To investigate the contribution of all three sources of information, we asked participants to search a computer generated “virtual” room for targets. Participants were provided with either only visual information, or visual supplemented with body-based information for all movement (walk group) or rotational movement (rotate group). The walk group performed the task with near-perfect efficiency, irrespective of whether a rich or impoverished visual scene was provided. The visual-only and rotate groups were significantly less efficient, and frequently searched parts of the room at least twice. This suggests full physical movement plays a critical role in navigational search, but only moderate visual detail is required

    Nada Jarrar’s A Good Land : A Multilateral Trauma

    Get PDF
    Trauma is not restricted to a particular place or a particular time. War memories intrude all nations and traumatize them. Following the crisis of the civil war in Lebanon, the invasion upon Palestine, the misery of Holocaust, and the wretchedness of World War II, many literary texts tackle them to show the traumatic experience of the individual. A Good Land by Nada Jarrar describes different traumatized nations and shows how the effect of trauma is one upon many individuals from different backgrounds. This research sets out to prove that the three different characters in the novel suffer from trauma. Kamal represents the Palestinian traumatic experience, Laila represents the Lebanese traumatic experience, and Margo represents the Jewish traumatic experience. This study focuses on the basic concepts of trauma. It shows how trauma affects identity. In addition, it displays the symptoms of Post Traumatic Stress Disorder (PTSD) and examines how different characters present different symptoms.The research discusses the novel’s thematic representation of trauma. It focuses on trauma theory specifically the idea of ‘’acting out’’ that is explained by Dominick LaCapra and Cathy Caruth. Moreover, the study shows the impact of trauma on identity through using the work of Dolores Herrero and Sonia Baelo-AlluĂ©. Eventually, this research sets out to prove the possibility of representing trauma in A Good Land by Nada Jarrar

    Visual Research Methods: A novel approach to understanding the experiences of compulsive hoarders: a preliminary study

    Objective: Compulsive hoarding is a syndrome characterised by excessive collecting and saving behaviour that results in cluttered living space and significant distress or impairment. This study set out to gain a greater understanding of the personal experiences of compulsive hoarders in addition to attaining their evaluations of attending a therapy group. Method: Using a participatory photography methodology, a purposive sample of 12 members of a hoarding therapy group were recruited. Participants were asked to take photographs which best captured their hoarding problems. The photographs were then used to encourage narrative dialogue in a subsequent semi structured interview. Results: Seven key themes emerged from the data including: Feelings of isolation and vulnerability, lifestyle disruption, losing and misplacing, clutter and metaphor, rationalisation of the acquisition of hoarded items, failed previous support and the benefits of a therapy support group. Conclusion: The study concluded that the experience of hoarding is both psychologically and physically distressing with numerous impacts upon everyday living and relationships. The study also concluded that visual research methods may be particularly helpful when generating qualitative evidence within this specialist field

    Anais Nin\u27s Under a glass bell : from interior fatality to psychological motion

    Get PDF
    Most of the critic ism on Anais Nin has been an overview of her entire work. Under A Glass Bell is included but, to my knowledge, no one has explored each individual story deeply enough since Nin herself recommends Under A Glass Bell as the book to begin with when reading or studying her works. Ibelieve that her recommendation is correct because Under A Glass Bell contains the nucleus of themes which she conc entrates on in all of her works, including the Diaries

    A first approach to understanding and measuring naturalness in driver-car interaction

    Get PDF
    With technology changing the nature of the driving task, qualitative methods can help designers understand and measure driver-car interaction naturalness. Fifteen drivers were interviewed at length in their own parked cars using ethnographically-inspired questions probing issues of interaction salience, expectation, feelings, desires and meanings. Thematic analysis and content analysis found five distinct components relating to 'rich physical' aspects of natural feeling interaction typified by richer physical, analogue, tactile styles of interaction and control. Further components relate to humanlike, intelligent, assistive, socially-aware 'perceived behaviours' of the car. The advantages and challenges of a naturalness-based approach are discussed and ten cognitive component constructs of driver-car naturalness are proposed. These may eventually be applied as a checklist in automotive interaction design.This research was fully funded by a research grant from Jaguar Land Rover, and partially funded by project n.220050/F11 granted by Research Council of Norway
