Innovativeness is defined as ‘originality by virtue of introducing new ideas’. Thus, innovative designs often break common visual habits and are evaluated as relatively unattractive at first sight (Leder & Carbon, 2005 ). In most empirical studies, attractiveness is measured only once. These measures do not capture the dynamic aspects of innovation. This paper presents a dynamic procedure, the Repeated Evaluation Technique (RET), that improves the validity of attractiveness evaluations. RET simulates time and exposure effects of everyday life. Using RET, we investigated the appreciation of different car designs varying in innovativeness and curvature. While the mere exposure theory (Zajonc, 1968 ) would predict a general increase of liking in increasing exposure, RET revealed dissociate effects depending on innovativeness. Only innovative designs showed an increase in attractiveness. Low innovative designs were rated as being relatively attractive in the beginning, but did not profit from elaboration due to RET.

A proof of magnetic compass learning by pigeons under laboratory conditions has been attempted for decades, but all experiments
have failed so far. The aim of the present study was to test whether pigeons can learn magnetic compass directions in an operant
chamber if magnetic cues are presented as true spatial cues. Experimental sessions were carried out in the local geomagnetic
field and in magnetic fields with matched total intensity and inclination, but different directions generated with Helmholtz-coils.
Birds demonstrated successful learning with a performance level comparable to that in learning studies with magnetic anomalies.
In addition, we compared the data from magnetic learning in the laboratory with performance from homing experiments in the
field. The birds that were more successful in the learning experiment had vanishing bearings farther away from the home direction
than the group mean at unfamiliar, but not at familiar sites. This might suggest that better learners explore unknown locations
in a different way. Our findings represent the first evidence for operant magnetic compass learning in pigeons and also provide
a link between behavioural data from the field and the laboratory. 相似文献

We explored how apparently painful stimuli and the ability to identify with the person on whom the pain is inflicted modulate
EEG suppression in the mu/alpha range (8–12 Hz). In a 2 × 2 design, we presented pictures of hands either experiencing needle
pricks or being touched by a Q-tip. In the dissimilar-other condition, the hand was assigned to a patient suffering from a neurological disease in which Q-tips inflicted pain, whereas
needle pricks did not. In the similar-other condition, the hand was assigned to a patient who responded to stimulation in the same way as the healthy participant. Participants
were instructed to imagine the feeling of the person whose hand was shown and to evaluate his or her affective state. Pain
conditions elicited greater EEG suppression than did nonpain conditions, particularly over frontocentral regions. Moreover,
an interaction between pain and similarity revealed that for similar others, the pain effect was significant, whereas in the
dissimilar-other group, suppression was equally large in the pain and no-pain conditions. We conclude that mu/alpha suppression
is elicited both automatically, by observing a situation that is potentially painful for the observer, and by empathy for
pain, even if the other person is different from oneself. 相似文献

Abstract : The article provides a brief biographical introduction of Lutheran Bishop Helmut Frenz, co‐founder of the Committee for Peace, credited with saving at least 6,000 lives of persecuted Chileans following the September 1973 military coup at the hands of the brutal general Agosto Pinochet. Excerpts from Frenz' book, Mi Vida Chilena, document Pinochet's acknowledgment that torture was the regime's official policy, and share the poignant story of one suspected leftist's brutal torture. 相似文献

Despite fruitful research in experimental aesthetics, the dynamics of aesthetics, i.e., the processes involved in art perception, have received little attention. Concerning representational art, two aspects seem most important in this respect: style and content. In two experiments, we examined the dynamics of processing of style and content by means of the microgenetic approach. This approach systematically varies perceptual conditions to find out about the stages involved in the formation of percepts – their microgenesis. Participants gave similarity ratings for pairs of pictures that were fully crossed in style (artist) and content (motif). Presentation times were systematically varied between 10, 50, 202 and 3000 ms (Experiment 1) plus unlimited presentation time (Experiment 2). While effects of content were present at all presentation times, effects of style were traceable from 50 ms onwards. The results show clear differences in the microgenesis of style and content, suggesting that in art perception style follows content. 相似文献

For both Han F. de Wit and Stanislav Grof, spirituality constitutes an essential part of humaneness; a life built on materialism is deemed an impoverished life. For de Wit, spirituality yields courage, compassion, joy, clarity of mind, and consequently wisdom. For Grof, personal spiritual experiences gained during altered states of consciousness are of central interest. After defining spirituality, these views, built on long-term personal experiences of the authors and those of others, are explicated in detail. Both authors describe their respective approaches to spiritual development. In either approach, third-person knowledge and judgments (e.g., on humanness) have to be supplemented by first-person knowledge and judgments arrived at appropriately (e.g., on humaneness). 相似文献

An information-theoretic framework is used to analyze the knowledge content in multivariate cross classified data. Several related measures based directly on the information concept are proposed: the knowledge content (S) of a cross classification, its terseness (Zeta), and the separability (Gamma
X
) of one variable, given all others. Exemplary applications are presented which illustrate the solutions obtained where classical analysis is unsatisfactory, such as optimal grouping, the analysis of very skew tables, or the interpretation of well-known paradoxes. Further, the separability suggests a solution for the classic problem of inductive inference which is independent of sample size. 相似文献
