When accepting a parcel from another person, we are able to use information about that person’s movement to estimate in advance
the weight of the parcel, that is, to judge its weight from observed action. Perceptual weight judgment provides a powerful
method to study our interpretation of other people’s actions, but it is not known what sources of information are used in
judging weight. We have manipulated full form videos to obtain precise control of the perceived kinematics of a box lifting
action, and use this technique to explore the kinematic cues that affect weight judgment. We find that observers rely most
on the duration of the lifting movement to judge weight, and make less use of the durations of the grasp phase, when the box
is first gripped, or the place phase, when the box is put down. These findings can be compared to the kinematics of natural
box lifting behaviour, where we find that the duration of the grasp component is the best predictor of true box weight. The
lack of accord between the optimal cues predicted by the natural behaviour and the cues actually used in the perceptual task
has implications for our understanding of action observation in terms of a motor simulation. The differences between perceptual
and motor behaviour are evidence against a strong version of the motor simulation hypothesis.

Bloomfield''s “Linguistics as a Science” (1930/1970), Language (1933/1961), and “Language or Ideas?” (1936a/1970), and Skinner''s Verbal Behavior (1957) and Science and Human Behavior (1953) were analyzed in regard to their respective perspectives on science and scientific method, the verbal episode, meaning, and subject matter. Similarities between the two authors were found. In particular both asserted that (a) the study of language must be carried out through the methods of science; (b) the main function of language is to produce practical effects on the world through the mediation of a listener; and (c) a physicalist conception of meaning. Their differences concern the subject matter of their disciplines and their use of different models for the analysis of behavior. Bloomfield''s linguistics and Skinner''s functional analysis of verbal behavior are complementary approaches to language. 相似文献

This article examines how emotional reactions to political events shape public opinion. We analyze political discussions in which people voluntarily engage online to approximate the public agenda: Online discussions offer a natural approach to the salience of political issues and the means to analyze emotional reactions as political events take place in real time. We measure shifts in emotions of the public over a period that includes 2 U.S. presidential elections, the 9/11 attacks, and the start of military action in Afghanistan and Iraq. Our findings show that emotional reactions to political events help explain approval rates for the same period, which casts novel light on the mechanisms that mediate the association between agenda setting and political evaluations. 相似文献

This paper is based on one idea and built around one clinical experience that helped me to broaden my comprehension of it. The idea, underlying the work of several authors, is that when the analytic field is saturated with primitive and unintegrated mental contents, the analyst’s somatic countertransference is a precious indicator of a deep, dissociated form of communication. The clinical experience concerns the difficult elaboration of a complex, multifaceted countertransference that took place during the early stages of the analysis of a sensitive patient who used to communicate in a very dissociated way and that I found hard to contain. This experience, closely described in the article, led me to formulate the clinical idea that the transference field may be made of distinct layers (psychoid, affective, verbal), and that each one of them may potentially convey dissociated, even contrasting bits of information. The corollary of this is that the analyst should be ready to accept contrasting sensations, feelings and thoughts at the same time, as they might be the basic ingredients of a complex reverie. The analyst could find himself/herself in front of his/her own internal unelaborated multiplicity before a symbolic image may emerge to link the scattered pieces of the experience. Nevertheless, the heart of this paper is not about suggesting an idea, but in the sharing of a complex working through, which fostered the birth of a new, more human relational perspective: the capacity of being together in time, in a transitional space where there is neither total separation nor fusion. 相似文献

AbstractWe argue that separation-survivability is a significant developmental fetal milestone beyond which abortion is only rarely and exceptionally morally justifiable. Secondly, we argue that the continuous nature of prenatal development, and simultaneous parallel development and actuation of intrinsic and contingent potentiality that eventually results in the development of a person capable of moral thoughts and deeds, implies continuously incremental moral significance. We propose that the moral justifiability of each instance of non-therapeutic pre-viable termination should be the product of an internal dialectic or “moral enquiry”. Arguments should be of increasing power in order to trump the sliding-scale increase in prenatal moral significance. We agree that sentience is morally significant, but argue that survivability is of predominant importance, since human beings who have the potentiality of separate, relatively independent lives, should, normally, be allowed to continue living. We argue for a moderate position on abortion. 相似文献
