Temporal order judgements as a sensitive measure of the spatial bias in patients with visuospatial neglect

Visuospatial neglect is not a unitary phenomenon, but can be better considered a syndrome, consisting of a multitude of different spatial and non‐spatial components. In this study, we used a temporal order judgement (TOJ) test in a large sample of stroke patients (n = 73) to scrutinize the contribution of a spatial bias to the performance on shape cancellation and line bisection tests. In the TOJ test, patients were presented with two elements, one in each visual field, after which the one needed to indicate which of the two elements was presented earlier. For each visual field, the presentation of the stimuli was determined by a staircase procedure where the interval between the two stimuli was determined by the performance of the patient. Results indicated that the strength of the spatial bias was strongly correlated with an object cancellation test, but not with a line bisection test. We argue that these findings are explained by differences in the extent to which a spatial bias determines performance on both tasks: In contrast to shape cancellation tests, successful performance on line bisection tests depends primarily on an object‐based, allocentric representation of space, unrelated to any spatial bias in the detection of elements in the contralesional visual field.     

Photo-Elicitation Interviews with Vulnerable Populations: Practical and Ethical Considerations

Photo-elicitation is a qualitative interview technique where researchers solicit responses, reactions, and insights from participants by using photographs or other images as stimuli. Images can be researcher-generated or participant-generated and each has particular benefits and challenges. Though not new, the use of images within criminology is an underused technique. In this paper we advocate the use of photo-elicitation techniques suggesting that they offer a powerful addition to standard data collection and presentation techniques. In making our case, we draw on our experiences from an 18-month long photo-ethnography of people living in rural Alabama who use methamphetamine. The ethnography consisted of formal interviews and informal observations with 52 participants and photography of 29 of them. While we draw on our overall experiences from the project we focus specifically on the photographs generated by, and taken of, one key participant—Alice. We demonstrate the benefits and challenges of using photo elicitation interviews with vulnerable individuals such as Alice, by considering themes such as representation, empowerment and emotionality. Additionally, we highlight the practical and ethical issues that confront researchers who incorporate the visual into their research.     

Fictionalism about musical works

The debate concerning the ontological status of musical works is perhaps the most animated debate in contemporary analytic philosophy of music. In my view, progress requires a piecemeal approach. So in this article I hone in on one particular musical work concept – that of the classical Western art musical work; that is, the work concept that regulates classical art-musical practice. I defend a fictionalist analysis – a strategy recently suggested by Andrew Kania as potentially fruitful – and I develop a version of such an analysis in line with a broad commitment to philosophical naturalism.

A distinction concerning vision-for-action and affordance perception

In this paper, I offer a discussion concerning the conceptual connection between the notion of vision-for-action and the one of affordance perception. I first analyze the notion of vision-for-action. I then analyze a notion usually coupled with it: the notion of affordance perception, the main insights behind which are guiding several current neuroscientific enterprises and the related philosophical speculations. Then, I argue that we should not couple these two notions with a light heart: though these two processes can be, from a theoretical point of view, related, we should be careful in inferring the actual and effective occurrence of the latter in the presence of the former. This will be done by carrying out a conceptual analysis of the experimental evidence coming from the ‘Two Visual Systems Model’, which is the main reference in the literature on affordance perception and vision-for-action. My point has strong philosophical implications for our view concerning the best interpretation of how vision-for-action really works, and the specific relation it actually entertains with affordance perception.     

Eye See What You Are Saying: Testing Conversational Influences on the Information Gleaned from Home‐Loan Disclosure Forms

The federal government mandates the use of home‐loan disclosure forms to facilitate understanding of offered loans, enable comparison shopping, and prevent predatory lending. Predatory lending persists, however, and scant research has examined how salespeople might undermine the effectiveness of these forms. Three eye‐tracking studies (a laboratory simulation and two controlled experiments) investigated how conversational norms affect the information consumers can glean from these forms. Study 1 was a laboratory simulation that recreated in the laboratory; the effects that previous literature suggested is likely happening in the field, namely, that following or violating conversational norms affects the information that consumers can glean from home‐loan disclosure forms and the home‐loan decisions they make. Studies 2 and 3 were controlled experiments that isolated the possible factors responsible for the observed biases in the information gleaned from these forms. The results suggest that attentional biases are largely responsible for the effects of conversation on the information consumers get and that perceived importance plays little to no role. Policy implications and how eye‐tracking technology can be employed to improve decision‐making are considered. Copyright © 2015 John Wiley & Sons, Ltd.     

Hegel,Danto, Adorno,and the end and after of art

In this paper, I consider Adorno's claim that art is at, or is coming to, an ‘end’. I consider Adorno's account in relation to the work of Arthur Danto and G. W. F. Hegel. I employ Danto's account, together with two distinct interpretive glosses of Hegel's account, as heuristic devices in order to clarify both Adorno's own arguments, and the context within which they are being advanced. I argue that while Danto and Hegel see art as coming to an end autonomously, owing to art's successful realization of its governing principle, Adorno by contrast sees art as coming to an end heteronomously. Art's narrative is forcibly broken off, rather than completed. Adorno's account, indebted to Hegel, of art's commitment both to autonomy and the realization of ‘spiritual needs’ is explored in order to clarify how, on Adorno's view, this has happened to art; and why, precisely, he believes art is coming to an end.     

Visualized Collective Memories: Social Representations of History in Images Found in Finnish History Textbooks

This study focuses on visual collective memory, a topic that has long been neglected in the social sciences and particularly in social psychological research on social representations of history. It explores the contents and meanings of images in the construction of Finnish national history. Through examination of official history writing, a better understanding is sought of how collective memory is constructed as part of history politics. The data for the present study consist of images (N = 541) included in recent textbooks on Finnish history. Barthes' three‐meaning approach is used in combination with qualitative content analysis to examine a large corpus of images. The visualized collective memory is approached from five perspectives: (i) the years of memory; (ii) the places of memory; (iii) the themes of memory; (iv) the main actors and (v) the silence of memory. The investigation shows that, in official discourse, politics, culture and war are the main contents of Finnish visual collective memory. The key actors in the narrative are politicians, especially the eighth president of Finland, Urho Kekkonen. The most important moments in time are situated in the war years 1918 and 1939, while the geographical focus is the central square in the capital, Helsinki. The result is a national history that is positive, homogeneous and exclusive. Copyright © 2016 John Wiley & Sons, Ltd.     

Visual discrimination of delayed self-generated movement reveals the temporal limit of proprioceptive–visual intermodal integration

This study examined the intermodal integration of visual–proprioceptive feedback via a novel visual discrimination task of delayed self-generated movement. Participants performed a goal-oriented task in which visual feedback was available only via delayed videos displayed on two monitors—each with different delay durations. During task performance, delay duration was varied for one of the videos in the pair relative to a standard delay, which was held constant. Participants were required to identify and use the video with the lesser delay to perform the task. Visual discrimination of the lesser-delayed video was examined under four conditions in which the standard delay was increased for each condition. A temporal limit for proprioceptive–visual intermodal integration of 3–5 s was revealed by subjects’ inability to reliably discriminate video pairs.     

Revisiting the looking at nothing phenomenon: Visual and semantic biases in memory search

When visual stimuli remain present during search, people spend more time fixating objects that are semantically or visually related to the target instruction than looking at unrelated objects. Are these semantic and visual biases also observable when participants search within memory? We removed the visual display prior to search while continuously measuring eye movements towards locations previously occupied by objects. The target absent trials contained objects that were either visually or semantically related to the target instruction. When the overall mean proportion of fixation time was considered, we found biases towards the location previously occupied by the target, but failed to find biases towards visually or semantically related objects. However, in two experiments the pattern of biases towards the target over time provided a reliable predictor for biases towards the visually and semantically related objects. We therefore conclude that visual and semantic representations alone can guide eye movements in memory search, but that orienting biases are weak when the stimuli are no longer present.
