Background Biobank participants often do not understand much of the information they are provided as part of the informed consent process, despite numerous attempts at simplifying consent forms and improving their readability. We report the first assessment of biobank enrollees’ comprehension under an "integrated consent” process, where patients were asked to enroll in a research biobank as part of their normal healthcare experience. A number of healthcare systems have implemented similar integrated consent processes for biobanking, but it is unknown how (...) much patients understand after enrolling under these conditions. Methods: We recruited patients who enrolled in a biobank while in a healthcare setting when receiving ordinary care. We assessed knowledge of consent materials using 11 true/false questions drawn from a well-known biobank knowledge test. After reviewing the results from 114 participants, we revised the consent form and repeated the knowledge assessment with 144 different participants. Results: Participants scored poorly on the knowledge test in both rounds, with no significant differences in overall scores or individual items between the rounds. In Phase 1, participants answered 53% of the questions correctly, 25% incorrectly, and 22% “I don’t know.” In Phase 2, participants answered 53% of questions correctly, 24% incorrectly, and 23% “I don’t know.” Participants scored particularly poorly on questions about data sharing and accessing medical records. Conclusions: Enrollees under an integrated consent model had significant misunderstandings that persisted despite an attempt to improve information specifically about those topics in a consent form. These results raise challenges for current approaches that attribute misunderstanding to overly complex consent forms. They also suggest that the pressures of the clinic may compound other problems with patient understanding of biobank consent. As health systems increasingly blend research and care, they may need to rethink their approach to educating patients about participation in a biobank. (shrink)

Faces are complex stimuli that can be described via intuitive facial features like the eyes, nose, and mouth, “configural” features like the distances between facial landmarks, and features that correspond to computations performed in the early visual system (e.g. oriented edges). With regard to this latter category of descriptors, adult face recognition relies disproportionately on information in specific spatial frequency and orientation bands: Many recognition tasks are performed more accurately when adults have access to mid-range spatial frequencies (8-16 cycles/face) and (...) horizontal orientations (Dakin & Watt, 2009). In the current study, we examined how this information bias develops in middle childhood. We recruited children between the ages of 5-10 years old to participate in a simple categorization task that required them to label images according to whether they depicted a face or a house. Critically, children were presented with face and house images comprised either of primarily horizontal orientation energy, primarily vertical orientation energy, or both horizontal and vertical orientation energy. We predicted that any bias favoring horizontal information over vertical should be more evident in faces than in houses, and also that older children would be more likely to show such a bias than younger children. We designed our categorization task to be sufficiently easy that children would perform at near-ceiling accuracy levels, but with variation in response times that would reflect how they rely on different orientations as a function of age and object category. We found that horizontal bias for face detection (but not house detection) correlated significantly with age, suggesting an emergent category-specific bias for horizontal orientation energy that develops during middle childhood. These results thus suggest that the tuning of high-level recognition to specific low-level visual features takes take place over several years of visual development. (shrink)

The pull to coordinate with other individuals is fundamental, serving as the basis for our social connectedness to others. Discussed is a dynamical and ecological perspective to joint action, an approach that embeds the individual’s mind in a body and the body in a niche, a physical and social environment. Research on uninstructed coordination of simple incidental rhythmic movement, along with research on goal‐directed, embodied cooperation, is reviewed. Finally, recent research is discussed that extends the coordination and cooperation studies, examining (...) how synchronizing with another, and how emergent social units of perceiving and acting are reflected in people’s feelings of connection to others.

It is some 900 years before Christ that we find the most ancient traces of two innovations which were to have incalculable consequences for the future of mankind. The evolution of civilization has, in fact, been marked by a clean break located at the era when man discovered the rudiments of agriculture and animal husbandry and began to produce his own food. Whereas for the three million years during which he had to provide for his needs exclusively through hunting, fishing (...) and gathering, his progress was extremely slow, the adoption of a new way of life based on agriculture and animal husbandry allowed man to transform himself in less than twelve thousand years from deer hunter into astronaut.

In this illuminating work, Dennis J. Schmidt examines tragedy as one of the highest forms of human expression for both the ancients and the moderns.

Siegfried J. Schmidt is closely associated in Germany with the cross-disciplinary research programme of Radical Constructivism. In Histories & Discourses he carries out a change of perspective from media and communication studies to studies of culture and the philosophy of language.His ‘rewriting’ of constructivism shows that classical constructivism shares some fundamental assumptions with realism, and he creates a new vocabulary which allows us to understand how we construct truth, identity, ethics, etc., without using any point of reference which lies (...) beyond our culture.

The results of four experiments provide evidence for controlled processing in the absence of awareness. Participants identified the colour of a neutral distracter word. Each of four words was presented in one of the four colours 75% of the time or 50% of the time . Colour identification was faster when the words appeared in the colour they were most often presented in relative to when they appeared in another colour, even for participants who were subjectively unaware of any contingencies (...) between the words and the colours. An analysis of sequence effects showed that participants who were unaware of the relation between distracter words and colours nonetheless controlled the impact of the word on performance depending on the nature of the previous trial. A block analysis of contingency-unaware participants revealed that contingencies were learned rapidly in the first block of trials. Experiment 3 showed that the contingency effect does not depend on the level of awareness, thus ruling out explicit strategy accounts. Finally, Experiment 4 showed that the contingency effect results from behavioural control and not from semantic association or stimulus familiarity. These results thus provide evidence for implicit control. (shrink)

A wide-ranging attempt to develop a theory of ethical life from a hermeneutic understanding of language.

Context: Philosophical debates in recent decades have developed new ways of dealing with old philosophical problems such as reality, truth, knowledge, language, communication, and action. These new approaches deserve serious consideration because they can improve the discourse of radical constructivism. Problem: This paper discusses the following problem: How can we overcome dualistic and ontological approaches to basic philosophical problems – problems that are relevant to all scientific domains? Method: The method applied here can be roughly described as a transition from (...) entities/substantives/identities to actions and processes, the actions and processes from which so-called entities result. Action-orientation – or an actor-based process – is necessarily combined with sense-orientation as provided by culture and society. Results: The paper demonstrates how the problems mentioned above can be reformulated in a non-dualistic and non-ontological way. Implications: Opening up constructivist thinking to insights provided by neighbouring philosophical approaches facilitates interdisciplinary cooperation and helps overcome dualistic remnants – as well as the cognitive one-sidedness of traditional constructivism.

A revised translation of Heidegger's most important work.

Wie wirklich ist die Wirklichkeit? Können wir einen sicheren erkennenden Zugang zu”der Wirklichkeit“gewinnen? Und wie ist die Wahrheit bzw. die Objektivität dieses Zugangs zu bewerten? Welche Rolle spielt die Sprache beim Umgang mit”der Wirklichkeit“? Dominiert im Erkenntnisprozess das Subjekt oder das Objekt? Ja, gibt es überhaupt etwas”da draußen“, oder ist alles nur unsere Konstruktion? In immer neuen Beschreibungsanläufen wird in diesem Buch versucht, plausible Zusammenhänge zwischen Themen aus dem weiten Umkreis der Wirklichkeitsdebatten herzustellen. Es geht, wie H. Putnam u.a. zu (...) sagen pflegen, um descriptions and redescriptions - und dafür soll eine epistemologisch entspanntere Argumentationsweise entworfen werden. Der Zweck der einleitenden Kapitel 1-11 besteht darin, interessante Ansatzpunkte, Startideen, Argumente und Varietäten unterschied-licher Beschreibungen zu den jeweilige Themen vorzustellen. Durch die Auswahl der vorgestellten Argumentationen soll die Tendenz der eigenen Problembehandlung im zweiten Teil sozusagen vorlaufend markiert werden, ohne dass damit Identitäten in der Theoriebildung behauptet werden. Wohl aber soll damit auf die Anschlussfähigkeit von Argumentationen in verschiedenen theoretischen Kontexten verwiesen werden. Der zweite Teil bietet eine strikt Prozess-orien-tierte Beschreibung von Themen aus dem Umkreis der Wirklichkeitsdebatte, die Anspruch auf sinnvolle Vorläufigkeit erhebt und sich bemüht, hartnäckige philosophische Probleme aufzulösen. - Damit ist auch eine Abkehr vom”klassischen“Konstruktivismus markiert.
