Only one of two keys reinforces the subject with food. This key can assume one of two colors, each associated with a different fixed-ratio schedule for obtaining reinforcement. The function of the second key is to permit the animal to switch from the long schedule to the short schedule. If the difference between the ratio schedules is large enough, a preference for the shorter schedule is demonstrable. A quantitative index of preference is obtained as follows: each time the animal switches to the shorter schedule, the number of pecks required to produce the next switch is increased. As the “ante” on the switching key increases, the effective difference between the two ratio schedules decreases. After each food reinforcement, when the bird is exposed to the choice-situation, it takes longer before the bird switches again. This is used to “titrate” the bird's preference. If it does not switch within x sec, the progressively increasing ratio schedule of the switching key is decreased. A specific value, in terms of a rather specific number of responses the bird settles at on the choice key, is obtained. This equilibrium is employed as a dependent variable. Several variables of which it is a function are explored. 相似文献

Thom? pleads for a form of psychoanalytic training in which the critical appropriation of psychoanalytic and humanistic knowledge as well as therapeutic competence are the focus and in which the personal analysis (super-therapy) is no longer overvalued. It seems possible to limit the length of training analyses. Qualification for professional practice should be worked out exclusively within the training institute and in close collaboration with instructors. 相似文献

Unfamiliar simultaneous face matching is error prone. Reducing incorrect identification decisions will positively benefit forensic and security contexts. The absence of view-independent information in static images likely contributes to the difficulty of unfamiliar face matching. We tested whether a novel interactive viewing procedure that provides the user with 3D structural information as they rotate a facial image to different orientations would improve face matching accuracy. We tested the performance of ‘typical’ (Experiment 1) and ‘superior’ (Experiment 2) face recognizers, comparing their performance using high-quality (Experiment 3) and pixelated (Experiment 4) Facebook profile images. In each trial, participants responded whether two images featured the same person with one of these images being either a static face, a video providing orientation information, or an interactive image. Taken together, the results show that fluid orientation information and interactivity prompt shifts in criterion and support matching performance. Because typical and superior face recognizers both benefited from the structural information provided by the novel viewing procedures, our results point to qualitatively similar reliance on pictorial encoding in these groups. This also suggests that interactive viewing tools can be valuable in assisting face matching in high-performing practitioner groups. 相似文献

The authors investigated whether memory for object locations in pictures could be exploited to address known difficulties of designing query languages for picture databases. M. W. Lansdale's (1998) model of location memory was adapted to 4 experiments observing memory for everyday pictures. These experiments showed that location memory is quantified by 2 parameters: a probability that memory is available and a measure of its precision. Availability is determined by controlled attentional processes, whereas precision is mostly governed by picture composition beyond the viewer's control. Additionally, participants' confidence judgments were good predictors of availability but were insensitive to precision. This research suggests that databases using location memory are feasible. The implications of these findings for database design and for further research and development are discussed. 相似文献

The psychological and statistical literature contains several proposals for calculating and plotting confidence intervals
(CIs) for within-subjects (repeated measures) ANOVA designs. A key distinction is between intervals supporting inference about
patterns of means (and differences between pairs of means, in particular) and those supporting inferences about individual
means. In this report, it is argued that CIs for the former are best accomplished by adapting intervals proposed by Cousineau
(Tutorials in Quantitative Methods for Psychology, 1, 42–45, 2005) and Morey (Tutorials in Quantitative Methods for Psychology, 4, 61–64, 2008) so that nonoverlapping CIs for individual means correspond to a confidence for their difference that does not include zero.
CIs for the latter can be accomplished by fitting a multilevel model. In situations in which both types of inference are of
interest, the use of a two-tiered CI is recommended. Free, open-source, cross-platform software for such interval estimates
and plots (and for some common alternatives) is provided in the form of R functions for one-way within-subjects and two-way
mixed ANOVA designs. These functions provide an easy-to-use solution to the difficult problem of calculating and displaying
within-subjects CIs. 相似文献

The author shows that the accessible psychoanalytic unconscious is not timeless. Freud??s ??timeless unconscious??, which was ontologized by himself and his successors, proves to be fiction with negative consequences. Assuming ??timeless?? primary processes psychoanalysis as a therapy would bite the hand which feeds it. Instead of contrasting linear time to the cyclic personal experience of time, the author suggests to speak about the ??emergence of lived time?? and the ??new moments?? of encounter in the therapeutic situation, to emphasize the importance of the opportune moment for change in contrast to the cyclic repetition of transference. In order to understand and approach disorders of time perception knowledge of unconscious conflicts and defense processes remains crucial. Even dreams are not timeless. While our conscious mind works according to chronological patterns, the pictorial representation in the particular form of thinking asleep, dreaming, makes it possible to map different memory traces simultaneously. Freud??s speculations about the ??timeless unconscious?? and Nirvana may originate from a longing for redemption. In contrast the author??s final chapter deals with the potential life span and transience of some central psychoanalytic concepts. Not even those who prove to be very close to observation can be attributed with ??eternal life??. 相似文献

David Miller's theory of nationalism and national responsibility offers the leading alternative ‘anticosmopolitan’ theory of global justice. His theory claims that ‘nations’ may be held responsible for the benefits and harms resulting from their collective decisions. Nations may be held remedially responsible to help nations in need even where the former lack causal or moral responsibility, for example. This article critically examines Miller's position that remedial responsibilities – the responsibilities of nations to remedy others in need – can and should only be satisfied by nations. I argue that the characteristics that define and justify a particular understanding of nationalism extend to further constructions of identity, such as religious affiliation and other connections. The problem with Miller's position is that it is overly narrow by focusing solely on our national identities as the characteristic most relevant for determining remedial responsibilities. It is possible and desirable to widen our focus, enriching our understanding of global justice and remedial responsibility. Moreover, this wider perspective is an extension, and not a break from, Miller's position. Our shared identities should have significance for considerations of global justice and they can help us to develop a more robust view of anticosmopolitanism. 相似文献

The experiments described in the lead articles by Kowalski and Zimiles and by O'Hanlon and Roberson examine factors that lead to color term acquisition. These experiments touch on the debate regarding the relative contributions of language and concepts in word learning. In this reflection, we examine how conclusions concerning the debate depend deeply on the particular task presented to children, and we propose an alternative approach to studying color term acquisition. 相似文献
