One standard to rule them all?

It has been argued that an epistemically rational agent's evidence is subjectively mediated through some rational epistemic standards, and that there are incompatible but equally rational epistemic standards available to agents. This supports Permissiveness, the view according to which one or multiple fully rational agents are permitted to take distinct incompatible doxastic attitudes towards P (relative to a body of evidence). In this paper, I argue that the above claims entail the existence of a unique and more reliable epistemic standard. My strategy relies on Condorcet's Jury Theorem. This gives rise to an important problem for those who argue that epistemic standards are permissive, since the reliability criterion is incompatible with such a type of Permissiveness.     

What’s left? An eye movement study of the influence of interword spaces to the left of fixation during reading

In English and other alphabetic systems read from left to right, the useful information acquired during each fixational pause is generally reported to extend 14–15 character spaces to the right of each fixation, but only 3–4 character spaces to the left, and certainly no farther than the beginning of the fixated word. However, this leftward extent is remarkably small and seems inconsistent with the general bilateral symmetry of vision. Accordingly, in the present study we investigated the influence of a fundamental component of text to the left of fixation—interword spaces—using a well-established eyetracking paradigm in which invisible boundaries were set up along individual sentence displays that were then read. Each boundary corresponded to the leftmost edge of a word in a sentence, so that as the eyes crossed a boundary, interword spaces in the text to the left of that word were obscured (by inserting a letter x). The proximity of the obscured text during each fixational pause was maintained at one, two, three, or four interword spaces from the left boundary of each fixated word. Normal fixations, regressions, and progressive saccades were disrupted when the obscured text was up to three interword spaces (an average of over 12 character spaces) away from the fixated word, while four interword spaces away produced no disruption. These findings suggest that influential information from text is acquired during each fixational pause from much farther leftward than is generally realized and that this information contributes to normal reading performance. Implications of these findings for reading are discussed.     

What is the optimal position of low-frequency words across line boundaries? An eye movement investigation

When displaying text on a page or a screen, only a finite number of characters can be presented on a single line. If the text exceeds that finite value, then text wrapping occurs. Often this process results in longer, more difficult to process words being positioned at the start of a line. We conducted an eye movement study to examine how this artefact of text wrapping affects passage reading. This allowed us to answer the question: should word difficulty be used when determining line breaks? Thirty-nine participants read 20 passages where low-frequency target words were either line-initial or line-final. There was no statistically reliable effect of our manipulation on passage reading time or comprehension despite several effects at a local level. Regarding our primary research question, the evidence suggests that word difficulty may not need to be accounted for when determining line breaks and assigning words to new lines.     

Temporal dynamics of the eye–voice span and eye movement control during oral reading

The distance between eye movements and articulation during oral reading, commonly referred to as the eye–voice span, has been a classic issue of experimental reading research since Buswell (1921). To examine the influence of the span on eye movement control, synchronised recordings of eye position and speech production were obtained during fluent oral reading. The viewing of a word almost always preceded its articulation, and the interval between the onset of a word's fixation and the onset of its articulation was approximately 500 ms. The identification and articulation of a word were closely coupled, and the fixation–speech interval was regulated through immediate adjustments of word viewing duration, unless the interval was relatively long. In this case, the lag between identification and articulation was often reduced through a regression that moved the eyes back in the text. These results indicate that models of eye movement control during oral reading need to include a mechanism that maintains a close linkage between the identification and articulation of words through continuous oculomotor adjustments.     

Is emotional content obtained from parafoveal words during reading? An eye movement analysis

An eye-movement-contingent display change technique was employed to study whether adult readers extract semantic information from parafoveal words during reading. Three types of parafoveal preview conditions were contrasted: an emotional word, a neutral word, and an identical word condition. To have a maximally effective parafoveal manipulation, high-arousal emotional words (sex- and threat-related and curse words) were used as parafoveal previews. Readers' eye fixation patterns around the target word revealed no evidence for parafoveal semantic processing. Furthermore, the pupil size showed no signs for an emotional response triggered by an emotional word previewed parafoveally. These results are consistent with the view that, as a rule, only the fixated word is processed to a semantic level during reading.     

Unconscious perception or not? An evaluation of detection and discrimination as indicators of awareness

Most investigations of unconscious perception use a dissociation design in which an awareness variable (e.g., detection) is compared with a perceptual processing variable (e.g., identification). Unconscious perception is inferred when the awareness variable lacks sensitivity to the stimulus but evidence of perceptual processing is still obtained. In two studies we examined the relationship between word identification and detection (Study 1) or discrimination (words vs. nonwords; Study 2) with a variety of techniques. In both studies, dissociations suggestive of unconscious perception occurred when the data were examined with subjective threshold approaches, but these differences disappeared when the variables were compared with techniques derived from signal detection theory (SDT). These results do not support unconscious perception in subjective threshold paradigms. In addition, detection appears to be the most sensitive and appropriate task for assessing stimulus awareness, provided that several SDT assumptions are met.     

What is morally at stake when using algorithms to make medical diagnoses? Expanding the discussion beyond risks and harms

In this paper, we examine the qualitative moral impact of machine learning-based clinical decision support systems in the process of medical diagnosis. To date, discussions about machine learning in this context have focused on problems that can be measured and assessed quantitatively, such as by estimating the extent of potential harm or calculating incurred risks. We maintain that such discussions neglect the qualitative moral impact of these technologies. Drawing on the philosophical approaches of technomoral change and technological mediation theory, which explore the interplay between technologies and morality, we present an analysis of concerns related to the adoption of machine learning-aided medical diagnosis. We analyze anticipated moral issues that machine learning systems pose for different stakeholders, such as bias and opacity in the way that models are trained to produce diagnoses, changes to how health care providers, patients, and developers understand their roles and professions, and challenges to existing forms of medical legislation. Albeit preliminary in nature, the insights offered by the technomoral change and the technological mediation approaches expand and enrich the current discussion about machine learning in diagnostic practices, bringing distinct and currently underexplored areas of concern to the forefront. These insights can contribute to a more encompassing and better informed decision-making process when adapting machine learning techniques to medical diagnosis, while acknowledging the interests of multiple stakeholders and the active role that technologies play in generating, perpetuating, and modifying ethical concerns in health care.

     

Cognitive behaviour therapy versus eye movement desensitization and reprocessing for post-traumatic disorder – is it all in the homework then?

IntroductionTreatment of choice for post-traumatic stress disorder (PTSD) is either eye movement desensitization and reprocessing (EMDR) or trauma-focused cognitive behaviour therapy (TFCBT).ObjectiveThe aim of the present meta-analysis was to determine whether there are any differences between these two treatments with respect to efficacy and efficiency in treating PTSD.MethodWe performed a comprehensive literature search using several electronic search engines as well as manual searches of other review papers. Eight original studies involving 227 participants were identified in this manner.ResultsThere were no differences between EMDR and TFCBT on measures of PTSD. However, there was a significant advantage for EMDR over TFCBT in reducing depression (Hedge's g = 0.63). The analysis also indicated a difference in the prescribed homework between the treatments. Meta-regression analyses were conducted to examine the relationship between hours of homework and gains in depression and PTSD symptoms.ConclusionThese findings are discussed in terms of efficacy and cost-effectiveness and the use of homework in therapy.     

Procedures: do we really want to know them? An examination of the effects of procedural justice on self-esteem

This study examined the effects of procedural justice on state-dependent self-esteem using the group-value model and attribution theory to present competing theoretical perspectives. The group-value model predicts a positive relationship between self-esteem and fair procedures. In contrast, attribution theory suggests procedural fairness interacts with outcome favorability to influence self-esteem. Thus, fair procedures will result in higher self-esteem ratings than unfair procedures when the outcome is positive but will result in lower self-esteem ratings than unfair procedures when the outcome is negative. The results of a laboratory and field study provide converging evidence to support the attribution theory predictions. The results of a 2nd laboratory study suggest that self-esteem is influenced by outcome expectancies, not actual outcomes.     

Paradoxical consequences of Balzer''s and G?hde''s criteria of theoreticity. Results of an application to ten scientific theories

It is shown that the criteria of T-theoreticity proposed by Balzer and Gähde lead to strongly counterintuitive and in this sense paradoxical results: most of the obviously empirical or at least nontheoretical terms come out as theoretical. This is demonstrated for a lot of theories in different areas. On the way, some improved and some new structuralist theory-reconstructions are given. The conclusion is drawn that the T-theoreticity of a term cannot possibly be proved on the basis of the mathematical structure of theory T alone (as Gähde and Balzer suggest). Rather, an independent notion of pre-T-theoreticity and-more importantly-of empiricity is needed; i.e., not empirical and not pre-T-theoretical are independent, necessary but not sufficient conditions for T-theoretical (this is also a necessary complement of Sneed's original criterion). Finally it is asked whether the structuralist criterion of T-theoreticity complemented by such independent conditions would be a satisfactory answer to Putnam's challenge, and the answer again is negative: the criterion is not able to distinguish between empirically contentful and completely contentless (superfluous) theoretical terms.     

Does scientific thinking lead to success and sanity? An integration of attribution and attributional models

A motivational model is introduced that integrates conceptions of attributional antecedents with those of attributional consequences, and suggests that it is functional to make realistic attributions. This model is applied to the analysis of achievement behaviour and depression. The use of a new experimental paradigm designed to test the model's assumptions demonstrates that realistic attributions maximise performance. The model was also used to investigate whether depressives are more realistic than non-depressives. This research revealed that depressives draw more "pessimistic" conclusions from covariation information than non-depressives. In addition, depressives expect their partners to make more negative attributions about the depressives' outcomes than their partners in fact do. However, these negative views could not be traced back to faulty inferences from covariation information. Finally, research is described showing that, in addition to depressogenic attributions, certain evaluative cognitions need to be present in order to trigger depressive mood reactions.     

How strongly do word reading times and lexical decision times correlate? Combining data from eye movement corpora and megastudies

We assess the amount of shared variance between three measures of visual word recognition latencies: eye movement latencies, lexical decision times, and naming times. After partialling out the effects of word frequency and word length, two well-documented predictors of word recognition latencies, we see that 7–44% of the variance is uniquely shared between lexical decision times and naming times, depending on the frequency range of the words used. A similar analysis of eye movement latencies shows that the percentage of variance they uniquely share either with lexical decision times or with naming times is much lower. It is 5–17% for gaze durations and lexical decision times in studies with target words presented in neutral sentences, but drops to 0.2% for corpus studies in which eye movements to all words are analysed. Correlations between gaze durations and naming latencies are lower still. These findings suggest that processing times in isolated word processing and continuous text reading are affected by specific task demands and presentation format, and that lexical decision times and naming times are not very informative in predicting eye movement latencies in text reading once the effect of word frequency and word length are taken into account. The difference between controlled experiments and natural reading suggests that reading strategies and stimulus materials may determine the degree to which the immediacy-of-processing assumption and the eye–mind assumption apply. Fixation times are more likely to exclusively reflect the lexical processing of the currently fixated word in controlled studies with unpredictable target words rather than in natural reading of sentences or texts.     

Use them or lose them: Are manipulatives needed to assess numeracy and geometry performance in preschool?

In two studies, we investigated whether using three-dimensional (3D) manipulatives during assessment aided performance on a variety of preschool mathematics tasks compared to pictorial representations. On measures of children's understanding of counting and cardinality (n = 103), there was no difference in performance between manipulatives and pictures, with Bayes factors suggesting moderate evidence in favor of the null hypothesis. On a measure of children's shape identification (n = 93), there was no difference in performance between objects and pictures, with Bayes factors suggesting moderate evidence in favor of the null hypothesis. These results suggest flexibility in the materials that can be used during assessment. Pictures, or 2D renderings of 3D objects, which can be easily printed and reproduced, may be sufficient for assessing counting and shape knowledge without the need for more cumbersome concrete manipulatives.     

Real-time sharing of gaze data between multiple eye trackers–evaluation,tools, and advice

Technological advancements in combination with significant reductions in price have made it practically feasible to run experiments with multiple eye trackers. This enables new types of experiments with simultaneous recordings of eye movement data from several participants, which is of interest for researchers in, e.g., social and educational psychology. The Lund University Humanities Laboratory recently acquired 25 remote eye trackers, which are connected over a local wireless network. As a first step toward running experiments with this setup, demanding situations with real time sharing of gaze data were investigated in terms of network performance as well as clock and screen synchronization. Results show that data can be shared with a sufficiently low packet loss (0.1 %) and latency (M = 3 ms, M A D = 2 ms) across 8 eye trackers at a rate of 60 Hz. For a similar performance using 24 computers, the send rate needs to be reduced to 20 Hz. To help researchers conduct similar measurements on their own multi-eye-tracker setup, open source software written in Python and PsychoPy are provided. Part of the software contains a minimal working example to help researchers kick-start experiments with two or more eye trackers.     

Dignity and Animals. Does it Make Sense to Apply the Concept of Dignity to all Sentient Beings?

Although the idea of dignity has always been applied to human beings and although its role is far from being uncontroversial, some recent works in animal ethics have tried to apply the idea of dignity to animals. The aim of this paper is to discuss critically whether these attempts are convincing and sensible. In order to assess these proposals, I put forward two formal conditions that any conception of dignity must meet (non-redundancy and normative determinacy) and outline three main approaches which might justify the application of dignity to animals: the species-based approach, moral individualism and the relational approach. Discussing in particular works by Martha Nussbaum and Michael Meyer I argue that no approach can convincingly justify the extension of dignity to animals because all fail to meet the formal conditions and do not provide an appropriate basis for animal dignity. I conclude by arguing that the recognition of the moral importance of animals and their defense should appeal to other normative concepts which are more appropriate than dignity.     

Born to kill? A critical evaluation of homicide adaptation theory

Given the enormous harm that results from the intentional killing of humans by other humans, the development of etiological theories of homicide is an important task. Homicide Adaptation Theory (HAT) is one such attempt to explain why homicide occurs. In short, the proponents of HAT propose that humans possess a number of specific, evolved adaptations for killing that have been selected for because they managed to successfully solve recurrent adaptive problems in our ancestral past. In this paper it is argued that, although evolutionary approaches can potentially advance our understanding of homicide in important ways, the available evidence does not support the existence of specific adaptations for killing in humans. Specifically, I argue that the proponents of HAT have not provided: (a) a thorough analysis of the evolutionary costs and benefits of killing; (b) evidence for ‘special design’ features of homicide; or (c) a systematic comparative appraisal of killing among different species. Given this lack of evidence, HAT suffers in terms of its explanatory worth, relative to alternative evolutionary hypotheses, such as the idea that homicide is a by-product of other evolved adaptations.     

Organization and predictive power of general and relationship-specific attachment models: one for all, and all for one?

Given recent evidence for multiple attachment models, we examined the organization and predictive power of general and relationship-specific attachment representations in two samples using two distinct measures of attachment models. With regard to associations among relationship-specific models, peer models (romantic partner and friend) and parental models (mother and father) were more similar to each other than to any other models, and anxiety/self-model representations were more consistent across relationships than avoidance/other-model representations. With regard to links between general and specific models, romantic and friend models made the strongest and independent contributions to general models, and romantic relationship involvement moderated the importance of romantic models to general models. With regard to differential predictive power of multiple models, general, romantic partner, and mother attachment made unique contributions to well-being indicators; relationship outcomes, however, were only predicted by individuals' corresponding relationship-specific models. Implications for the measurement and conceptualization of adult attachment are discussed.
