Bisection tasks are used in research on normal space and time perception and to assess the perceptual distortions accompanying neurological disorders. Several variants of the bisection task are used, which often yield inconsistent results, prompting the question of which variant is most dependable and which results are to be trusted. We addressed this question using theoretical and experimental approaches. Theoretical performance in bisection tasks is derived from a general model of psychophysical performance that includes sensory components and decisional processes. The model predicts how performance should differ across variants of the task, even when the sensory component is fixed. To test these predictions, data were collected in a within-subjects study with several variants of a spatial bisection task, including a two-response variant in which observers indicated whether a line was transected to the right or left of the midpoint, a three-response variant (which included the additional option to respond “midpoint”), and a paired-comparison variant of the three-response format. The data supported the model predictions, revealing that estimated bisection points were least dependable with the two-response variant, because this format confounds perceptual and decisional influences. Only the three-response paired-comparison format can separate out these influences. Implications for research in basic and clinical fields are discussed. 相似文献

The term ‘Climategate’ refers to the episode in November 2009 when emails between climate scientists were stolen and published online. The content of this private correspondence prompted criticism from diverse commentators who cast doubts on the methods, claims, and members of the climate science community. In response, individual scientists and scientific institutions published statements responding to the allegations of scientific fraud. Gieryn's concept of ‘boundary-work’ can be used to analyse the rhetoric of scientists in situations where their legitimacy is disputed. More specifically, boundary-work can be used to analyse the responses of scientists in terms of: how they represent the attributes of science, what types of boundary-work they undertake (e.g. expulsion, expansion, and protection), and the professional interests that come into play. A boundary-work analysis of the commentaries published in the aftermath of Climategate reveals that scientists characterised climate science as consensual, asocial, and open. Scientists depicted climate science as consensual with the purpose of expelling dissenters and protecting areas of climate science from criticism. Scientists also described knowledge about climate as being ideally produced apart from society so that they could preserve their autonomy and exclude individuals who are accused of being ‘politically biased’. Scientists characterised climate science as necessarily open as the means to justify both existing and additional public funding for science and to avoid external corrective interventions against scientific opacity. Scientists and their critics alike interpreted the stolen emails as embarrassing deviations from the alleged social demands of a consensual, objective, and accessible science. 相似文献

It is well known in the field that culture and context play an important role in child rearing and parenting practices. However, many studies do not address the cultural dimension of attachment, although evidence indicates that aspects of early attachment differ across cultures. With the goal of comparing the quality of mother–baby interactions, this study analyzed attachment behaviors and maternal sensitivity in two settings: urban/non-Mapuche and rural/Mapuche in Chile. The sample was composed of 34 mother-baby dyads (17 urban/non-Mapuche and 17 rural/Mapuche) with 12-month-old children. During a feeding episode, the attachment style of the interaction was assessed with the Attachment during Stress scale, and maternal sensitivity was evaluated with the Child-Adult Relationship Experimental Index-Toddlers (CARE-Index). The groups differed in their interaction attachment style and in affective and proximity modalities: Urban/non-Mapuche mothers tended to have secure and ambivalent attachment styles, and rural/Mapuche mothers tended to have avoidant styles. When educational level is controlled, ethnicity group can explain the differences in mothers’ attachment styles. The findings of the study and their implications are discussed. 相似文献

It is still controversial to what extent neocortical consolidated memories are susceptible of change by processes of reconsolidation and transformation throughout experience, and whether the medial temporal lobes are necessary for this update of semantic consolidated memories, as they are for episodic remembering. We hypothesize that patients with amnestic mild cognitive impairment (aMCI) who have deficits in episodic memory may also have difficulties in updating information on added new features of objects. Sixteen participants with aMCI and 20 healthy control participants performed a semantic word-to-picture task, in which they were asked to identify as belonging to a given semantic category NEW objects, that have incorporated novel features, as well as OLD items, semantically and visually SIMILAR items and UNRELATED items. Patients with aMCI made a greater percentage of errors than healthy controls. Participants globally made greater percentages of errors in difficult types of items, namely NEW and SIMILAR, as compared to easier ones, OLD and UNRELATED. Importantly, an item by diagnostic group interaction effect was observed, and post hoc analysis showed that patients with aMCI made a higher percentage of errors than controls in NEW items only. In conclusion, patients with aMCI had a particular difficulty in identifying the NEW items of the word-to-picture task as compared to the control participants, supporting the concept of a flexible and dynamic conceptual knowledge system, involving the update of semantic memories and the integration of new attributes in a constant transformation process, which is impaired in these patients. 相似文献

RESUMENLa obra de Jerry A. Fodor ha tenido una determinante influencia en el desarrollo de la llamada “Psicología Cognitiva“. Durante todo ese tiempo el profesor Fodor ha publicado una gran cantidad de artículos y libros que actualmente se consideran clásicos de la psicología. Su influencia va más allá de la psicología y se le considera uno de los pioneros de la llamada “ciencia cognitiva”. En esta entrevista, realizada y presentada por el profesor García-Albea, Fodor hace un recuento de su biografía, obra y, también, de las relaciones que ha mantenido con otros autores de la filosofía y la psicología clásicos, como él, dentro de la ciencia cognitiva. Nos habla además, el profesor Fodor, de los principales conceptos de su teoría: lengua del pensamiento, modularidad, teoría funcionalista, etc. Para finalizar esta entrevista, el entrevistado realiza una reflexión sobre las teorías dominantes en ciencia cognitiva, y comenta el futuro de la psicología a la luz de las actuales propuestas en investigación. 相似文献

This study examined a moderated mediation model testing whether dysmorphic concern is related to behaviour altered to change appearance. This relationship is potentially mediated by depressive symptomatology (dysphoria and self-esteem) and ideas of reference about “laughing, commenting” and “attention, appearance,” and each mediated relationship moderated by sex. The sample was made up of 3377 adolescents from 12 to 18 years old (Mage = 14.52; SD = 1.65, 56.5% girls). The results showed that dysphoria and ideas of reference about “laughing, commenting” and “attention, appearance” partially mediated the relationship between dysmorphic concern and behavioural impairment related to body image. The relationship with dysphoria was moderated by sex, such that the mediation effect was stronger in girls than in boys. This result implies that girls who are worried about some characteristic of their appearance and show dysphoria are at greater risk of altered behaviour involving avoidance or controlling their appearance than boys. In addition, a possible risk of body dysmorphic disorder (3.45% of the sample) was found, with very prominent hiding behaviour using clothing or control behaviours, such as frequent weighing and looking at oneself in the mirror too much. Implications of these findings are discussed. 相似文献
