Based on evolutionary considerations, it was hypothesized that humans have been shaped to easily spot snakes in visually cluttered scenes that might otherwise hide camouflaged snakes. This hypothesis was tested in a visual search experiment in which I assessed automatic attention capture to evolutionarily-relevant distractor stimuli (snakes), in comparison with another animal which is also feared but where this fear has a disputed evolutionary origin (spiders), and neutral stimuli (mushrooms). Sixty participants were engaged in a task that involved the detection of a target (a bird) among pictures of fruits. Unexpectedly, on some trials, a snake, a spider, or a mushroom replaced one of the fruits. The question of interest was whether the distracting stimuli slowed the reaction times for finding the target (the bird) to different degrees. Perceptual load of the task was manipulated by increments in the set size (6 or 12 items) on different trials. The findings showed that snake stimuli were processed preferentially, particularly under conditions where attentional resources were depleted, which reinforced the role of this evolutionarily-relevant stimulus in accessing the visual system (Isbell, 2009). 相似文献

This study presents the adaptation of the Affective Norms for English Words (ANEW; Bradley & Lang, 1999a) for European Portuguese (EP). The EP adaptation of the ANEW was based on the affective ratings made by 958 college students
who were EP native speakers. Subjects assessed about 60 words by considering the affective dimensions of valence, arousal,
and dominance, using the Self-Assessment Manikin (SAM) in either a paper-and-pencil or a Web survey procedure. Results of
the adaptation of the ANEW for EP are presented. Furthermore, the differences between EP, American (Bradley & Lang, 1999a), and Spanish (Redondo, Fraga, Padrón, & Comesa?a, Behavior Research Methods, 39, 600–605, 2007) standardizations were explored. Results showed that the ANEW words were understood in a similar way by EP, American, and
Spanish subjects, although some sex and cross-cultural differences were observed. The EP adaptation of the ANEW is shown to
be a valid and useful tool that will allow researchers to control and/or manipulate the affective properties of stimuli, as
well as to develop cross-linguistic studies. The normative values of EP adaptation of the ANEW can be downloaded at . 相似文献

Abstract Studying the works of Freud and Lacan, the authors carried out research on perversion in childhood. Their work covered the perverse polymorphism of infantile sexuality and the perception of the anatomic difference between the sexes that leads the child to create sexual theories and fantasies. The phallic mother and the fetish are viewed as imaginary solutions directly related to the Oedipus and castration complexes. In perversion, a particular position is taken in relation to the Oedipus complex: a serious flaw occurs in the symbolization of the law, and the mechanisms of denial and disavowal take form. Sexuality requires a second “logical time,” separated from infancy by the latency period, in order to confirm (in action) that a fixed position of jouissance (enjoyment) has actually been established. This can only happen in a period after adolescent enhancement. The distinction between perverse traces and a perverse structure is made, taking into account the fact that, in the case of child analysis, the analyst should free the child from the family fantasy and help him/her to build his/her own fantasy. Campos Santoro V. et al. Perversion und Kindheit und Adoleszenz. Im Studium der Arbeiten von Freud und Lacan haben die Autoren Forschung über Perversion in der Kindheit gemacht. Die Studien behandeln den perversen Polymorphismus der infantilen Sexualität und die Wahrnehmung des anatomischen Unterschiedes zwischen den Geschlechtern, welche das Kind dazu führt, Sexual-Theorien und Phatasien zu schaffen. Die phallische Mutter und der Fetisch werden als imaginäre Lösungen angesehen, die sich direkt auf den Ödipus- und Kastrations-Komplex beziehen. Bei der Perversion wird eine besondere Position in Bezug auf den Ödipus angenommen; ein ernsthafter Mangel tritt bei der Symbolisierung des Rechts auf; die Mechanismen der Verneinung und der Verleugnung bilden sich. Sexualität erfordert eine zweite “logische Zeit”, von der Kindheit durch die Latenz Periode getrennt, um (in der Handlung) zu bestätigen, daß eine fixierte Position der jouissance (Vergnügung) sich tatsächlich etabliert hat. Das kann sich nur in einer Periode nach der adoleszenten Verstärkung ereignen. Es wird die Unterscheidung zwischen perversen Spuren und einer perversen Struktur gemacht, in Rechnung stellend, daß im Fall der Kinder-Analyse der Analytiker das Kind von der Familien-Phantasie befreien sollte und ihm/ihr helfen sollte, seine/ihre Phantasie auszubilden. Campos Santoro V. Perversión e infancia y adolescencia. Estudiando los trabajos de Freud y Lacan, los autores han investigado la perversión en la niñez. Los estudios cubren la sexualidad infantil perversa polimorfa y la percepción de la diferencia anatómica entre los sexos, que llevan al niño a crear teorías sexuales y fantasías. La madre fálica y el fetiche son vistos como soluciones imaginarias relacionadas directamente con el complejo de Edipo y de castración. La perversión, toma una posición particular en relación al Edipo; un fallo importante tiene lugar en la simbolización de la ley; los mecanismos de negación y repudio toman forma. La sexualidad requiere un segundo “tiempo lógico” separado de la infancia por el periodo de latencia, para confirmar (en acto) que una posición fija de jouissance (goce) se ha establecido. Esto solo puede ocurrir en un periodo posterior a la intensificación adolescente. La distinción entre las huellas perversas y la estructura perversa se ha hecho, teniendo en cuenta que, en el caso del análisis de niños, el analista debe librar al niño de la fantasía familiar y ayudar a el/ella a construir su propia fantasía. 相似文献

Floridi’s work, although diverse and multifaceted, portrays a solid coherence across his different lines of work. Among his wealth of interests and results, we highlight his recent work on information logics, on the ethics of information technology, and his rigorous (and vigorous) philosophical analysis of recent technological trends and developments in information technology. In the present article we illustrate, by means of some connecting arguments, the diversity and coherence of Floridi’s work. We also show how his work, although fundamentally philosophical in nature, can be used to build solid foundations for scientific and entrepreneurial endeavours of higher quality. More specifically, we discuss how the combination of results from the three lines of work referred to above can be used as ground for the organisation of higher quality programmes to augment the capabilities and effectiveness of governmental systems through information and communications technology, a trend that has been explored in many nations and that has been coined Electronic Government. Electronic Government programmes that improve the capabilities of citizens to interact with each other and with governments, as well as the capabilities of governments to listen to the needs and aspirations of citizens, have the potential to contribute to the construction of more democratic states. Electronic Government systems that rely on ready made models to prescribe to citizens how best they should interact with each other and with the public administration are, however, by construction non-democratic. Hence, it can be a moral and ethical matter for governments to choose which line of technological development they take. 相似文献

We examined how biasing time perception affects choice in a midsession reversal task. Given a simultaneous discrimination between stimuli S1 and S2, with choices of S1 reinforced during the first, but not the second half of the trials, and choices of S2 reinforced during the second, but not the first half of the trials, pigeons show anticipation errors (premature choices of S2) and perseveration errors (belated choices of S1). This suggests that choice depends on timing processes, on predicting when the contingency reverses based on session duration. We exposed 7 pigeons to a midsession reversal task and manipulated the reinforcement rate on each half of the session. Compared to equal reinforcement rates on both halves of the session, when the reinforcement rate on the first half was lower than on the second half, performance showed more anticipation and less perseveration errors, and when the reinforcement rate on the first half was higher than on the second half, performance showed a remarkable reduction of both types of errors. These results suggest that choice depends on both time into the session and the outcome of previous trials. They also challenge current models of timing to integrate local effects. 相似文献
