You'd Better Ask an Expert: Mitigating the Comprehensibility Effect on Laypeople's Decisions About Science‐Based Knowledge Claims

Research shows that laypeople rely more on their capabilities to make decisions about science‐based knowledge claims after reading comprehensible compared with less comprehensible topic information. This can be problematic, because complex science‐based issues usually cannot be understood fully without experts' further advice. The present study investigated whether making readers aware of the ‘epistemic topic complexity’ of an issue (i.e., the extent of existing topic knowledge, the complexity of relationships between concepts, and the existence of multiple expert perspectives) can mitigate this influence of comprehensibility. Undergraduate students read comprehensible or less comprehensible health texts with topic knowledge being described as complex, uncomplex, or not described at all. They reported whether they agreed with the claim and would rely on their decision. Results showed that after reading comprehensible information, participants' reliance on their decision increased less when they considered topic knowledge to be complex. Practical implications of the findings are discussed. Copyright © 2014 John Wiley & Sons, Ltd.     

Alternative Psychopharmakatherapie im Alter

In ?sterreich steigt der Anteil von ?lteren Menschen in der Bev?lkerung stetig an. Besonders die Anzahl der Mitbürger über 85 Jahre zeigte in den letzten 20 Jahren einen überproportionalen Zuwachs. Alterstypische Erkrankungen gewinnen deshalb zunehmend an sozialmedizinischer und volkswirtschaftlicher Bedeutung. Zu den h?ufigsten Alterserkrankungen z?hlen psychiatrische St?rungen, wie die Delir, Demenz und Depression, die ihrerseits wieder mit psychotischer Symptomatik, wie Wahn und Halluzinationen, Pers?nlichkeitsver?nderungen, Verhaltensauff?lligkeiten und gest?rtem Schlaf-Wachrhythmus einhergehen. Die h?ufigsten Gründe für eine Institutionalisierung gerontopsychiatrischer Patienten sind kognitive St?rungen begleitet von der Unf?higkeit, sich selbst zu versorgen, sich ausreichend zu pflegen und zu orientieren, sowie dem Auftreten einer Inkontinenz und von wahnhafter Symptomatik mit Aggressivit?t, Verhaltensst?rungen und n?chtlichen Unruhephasen. Da es durch falsche Diagnose und Therapie der im Alter überproportional h?ufigen Schlaf- und Verhaltensst?rungen bei Demenz sehr oft zu einem Circulus vitiosus mit kognitiver Verschlechterung, zunehmender Inkontinenz, Immobilit?t, Sturz- und Frakturneigung kommt, ist es wesentlich, das ?rztliche „Primum nil nocere“ zu beachten – die schonendsten Medikamente in niedrigster Dosierung über einen erforderlichen Zeitraum, aber nicht darüber, hinaus zu verordnen. Alternative Ma?nahmen k?nnen sowohl bei der Behandlung der h?ufigen Schlaf-Wachrhythmusst?rungen, als auch bei Verhaltensauff?lligkeiten bei Demenz sehr hilfreich für eine Verbesserung der Lebensqualit?t von Patient, Betreuer und Umgebung sein.     

Social Concepts and Judgments: A Semantic Differential Analysis of the Concepts Feminist, Man, and Woman

Male and female participants  ( N = 274)  made judgments about the social concepts of feminist , man , and woman on 63 semantic differential items. Factor analysis identified three basic dimensions termed evaluative, potency, and activity as well as two secondary factors called expressiveness and sexuality. Results for the evaluative dimension showed that the concept feminist was rated negatively with male participants rating feminist more negatively than female participants. In terms of potency, feminist was judged higher than man whereas the concept woman was rated low on this dimension. Participants also judged the concept feminist as low in expressiveness and rated woman as the most expressive. Feminist received low ratings on the erotic-sexual dimension (sexuality) by female participants and negative sexuality ratings by men. These results are discussed in terms of social role theory, gender stereotypes, and the changes in women's roles and behavior.     

Knowledge and True Belief in Early Analytic Philosophy1

Abstract

I argue that the sufficiency of true belief for knowledge was accepted by some principal figures in the early history of analytic philosophy, including Russell, Schlick, McTaggart, and Moore, among others.     

Individualism versus interactionism about social understanding

In the debate about the nature of social cognition we see a shift towards theories that explain social understanding through interaction. This paper discusses autopoietic enactivism and the we-mode approach in the light of such developments. We argue that a problem seems to arise for these theories: an interactionist account of social cognition makes the capacity of shared intentionality a presupposition of social understanding, while the capacity of engaging in scenes of shared intentionality in turn presupposes exactly the kind of social understanding that it is intended to explain. The social capacity in question that is presupposed by these accounts is then analyzed in the second section via a discussion and further development of Searle’s ‘sense of us’ and ‘sense of the other’ as a precondition for social cognition and joint action. After a critical discussion of Schmid’s recent proposal to analyze this in terms of plural pre-reflective selfawareness, we develop an alternative account. Starting from the idea that infants distinguish in perception between physical objects and other agents we distinguish between affordances and social affordances and cash out the notion of a social affordance in terms of “interaction-oriented representations”, parallel to the analysis of object affordances in terms of “action-oriented representations”. By characterizing their respective features we demonstrate how this approach can solve the problem formulated in the first part.     

Age-related differences in brain electrical activity during extended continuous face recognition in younger children, older children and adults

To examine the development of recognition memory in primary-school children, 36 healthy younger children (8-9 years old) and 36 healthy older children (11-12 years old) participated in an ERP study with an extended continuous face recognition task (Study 1). Each face of a series of 30 faces was shown randomly six times interspersed with distracter faces. The children were required to make old vs. new decisions. Older children responded faster than younger children, but younger children exhibited a steeper decrease in latencies across the five repetitions. Older children exhibited better accuracy for new faces, but there were no age differences in recognition accuracy for repeated faces. For the N2, N400 and late positive complex (LPC), we analyzed the old/new effects (repetition 1 vs. new presentation) and the extended repetition effects (repetitions 1 through 5). Compared to older children, younger children exhibited larger frontocentral N2 and N400 old/new effects. For extended face repetitions, negativity of the N2 and N400 decreased in a linear fashion in both age groups. For the LPC, an ERP component thought to reflect recollection, no significant old/new or extended repetition effects were found. Employing the same face recognition paradigm in 20 adults (Study 2), we found a significant N400 old/new effect at lateral frontal sites and a significant LPC repetition effect at parietal sites, with LPC amplitudes increasing linearly with the number of repetitions. This study clearly demonstrates differential developmental courses for the N400 and LPC pertaining to recognition memory for faces. It is concluded that face recognition in children is mediated by early and probably more automatic than conscious recognition processes. In adults, the LPC extended repetition effect indicates that adult face recognition memory is related to a conscious and graded recollection process rather than to an automatic recognition process.

The effect of visual word features on the acquisition of orthographic knowledge

Research with adults has shown that the distortion of visual word features, and in particular of the multiletter features within words, hampers word recognition. In this study, "CaSe MiXiNg" was employed to examine the effect of disrupting visual word features on the acquisition of orthographic knowledge in children. During the training, 18 beginning and 27 advanced readers (in Grades 2, 4, and 5) repeatedly read a set of pseudowords in either lowercase or mixed case. During this training, case mixing appeared to impair reading speed in both reader groups. At posttest, 1 day after the training, case format was either the same as or different from that during the training. Lowercase pseudowords were recognized faster after a lowercase training than after a mixed-case training. In a second study, case was found not to affect the rapid naming of single letters. The combined results suggest that case mixing disrupted the multiletter features in pseudowords and that the disruption of these features can affect the acquisition of orthographic knowledge.
