Template theories of visual pattern recognition assume the operation of preprocessing routines to deal with irrelevancies such as discrepancies in stimulus size. In three experiments where size was an irrelevant dimension, observers classified pairs of forms as either “same” or “different”. In Experiment I, the classification “different” was required when the stimuli shared the same form but a different orientation, and “same” when the stimuli shared the same form and orientation. Under these conditions RT was an increasing function of the magnitude of the size disparity between stimuli with equal slopes for “same” and “different” judgements. In Experiment II, “different” classifications were made to stimuli that had different forms, and “same” to figures with the same form. This stimulus set produced a size disparity function that interacted with response type; “different” responses had a shallower slope. Experiment III consisted of a mixed stimulus set drawn from both Experiment I and II. Stimuli that produced additive effects of size disparity and response type in Experiment I now produced an interaction between these two factors similar to the one observed in Experiment II. The results of these experiments are interpreted as evidence that previous contradictory results reported in the literature stem from differences in the way the stimulus set is constructed, and that size transformations can not be a necessary operation, at least when “different” judgements are made. The results are problematic for the view that size disparity effects in matching tasks are easily interpretable in terms of a primitive size normalization stage that precedes any comparison operations. 相似文献

While Freud’s account of melancholia stresses the role of a lost object, a Lacanian approach draws attention to the role of an intruding and excessive “real” object and the inability of the psychotic subject to adequately shield themselves from the traumatic jouissance associated with it. While initially these approaches seem to contradict one another, this short commentary argues that the loss of an imaginary (ego-supporting) object (as per Freud’s conceptualization of psychosis) may be coterminous with the invasive presence of an object of a different order—that of the Lacanian real. We are able to better appreciate the particularity of this invasive object by reference to Lacan’s notion—itself derived from Freud—of das Ding. Das Ding is that “object” of amassed primal jouissance, which—like a black hole—corresponds to its own absence and which, in its terrifying and sublime materializations, brings together the three crucial Freudian concepts of libidinal overproximity, unmodulated jouissance, and the death drive. 相似文献

This paper presents an account of how human spontaneous embryonic chimeras are formed. On the prevalent view in the philosophical literature, it is said that chimeras are the product of two embryos that fuse to form a new third embryo. We call this version of fusion synthesis. In contrast to synthesis, we present an alternative mechanism for chimera formation called incorporation, wherein one embryo incorporates the cells of a second embryo into its body. We argue that the incorporation thesis explains other types of chimera formation, which are better understood, and is more consistent than synthesis with what is known about embryological development. Incorporation also has different implications than synthesis and so avoids the philosophical puzzles that are often said to accompany embryonic chimera formation—puzzles which pose problems to the human embryo’s persistence from fertilization to the fetal stage of human development. 相似文献

Drawing upon the work of Adam Phillips and Ronald Britton the author highlights the intimidating and fear-inducing nature of the super-ego and the role of the therapist in supporting the judgements of the ego and liberating it from the domination of the super-ego. He goes on to explore the proposition that moral principles do not need to be oppressive in nature and that they can emanate from objects that are more akin to sexual or aesthetic objects. These themes are linked to Woodmansey’s conceptualistion of the punitive and humiliating super-ego, and the origin of the super-ego as an internalisation of an external conflict is outlined. The role of identifying a Cyclical Maladaptive Pattern as a focus and its contribution in identifying the super-ego and how it manifests in the client’s narrative are explored, as well as the crucial contribution of a playful stance on the part of therapist in subverting and undermining the intimidating strictures of the super-ego. 相似文献

Emotional rumination and inhibition were identified in the Emotion Control Questionnaire (ECQ—Roger and Nesshoever 1987; Roger and Najarian 1989) as two relatively independent dimensions of emotional style, and the two measures have subsequently been shown to be important moderator variables in a range of health and forensic settings. Two other dimensions that emerged in the ECQ, labelled aggression control and benign control, have been shown to form part of the extraversion constellation, and the present paper describes the construction and validation of a new scale focusing exclusively on rumination and inhibition. Revised and expanded item pools for the scales were subjected to exploratory and confirmatory factor analyses, which endorsed the two-factor structure. The new scales were validated concurrently against related scales in different samples, and were shown to be systematically related to two independent indices of health status. 相似文献

In timing perception studies, the timing of one event is usually manipulated relative to another, and participants are asked to judge if the two events were synchronous, or to judge which of the two events occurred first. Responses are analyzed to determine a measure of central tendency, which is taken as an estimate of the timing at which the two events are perceptually synchronous. When these estimates do not coincide with physical synchrony, it is often assumed that the sensory signals are asynchronous, as though the transfer of information concerning one input has been accelerated or decelerated relative to the other. Here we show that, while this is a viable interpretation, it is equally plausible that such effects are driven by shifts in the criteria used to differentiate simultaneous from asynchronous inputs. Our analyses expose important ambiguities concerning the interpretation of simultaneity judgement data, which have hitherto been underappreciated. 相似文献

Individuals diagnosed with major depressive disorder (MDD) often ruminate about their depression and their life situations, impairing their concentration and performance on daily tasks. We examined whether rumination might be due to a deficit in the ability to expel negative information from short-term memory (STM), and fMRI was used to examine the neural structures involved in this ability. MDD and healthy control (HC) participants were tested using a directed-forgetting procedure in a short-term item recognition task. As predicted, MDD participants had more difficulty than did HCs in expelling negative, but not positive, words from STM. Overall, the neural networks involved in directed forgetting were similar for both groups, but the MDDs exhibited more spatial variability in activation in the left inferior frontal gyrus (a region critical for inhibiting irrelevant information), which may contribute to their relative inability to inhibit negative information. 相似文献

In this paper, we link age differences in gaze patterns toward emotional stimuli to later mood outcomes. While one might think that looking at more positive emotional material leads to better moods, and looking at more negative material leads to worse moods, it turns out that links between emotional looking and mood depend on age as well as individual differences. Though older people can feel good by looking more at positive material, in some cases young adults actually feel better by engaging visually with the negative. These age effects are further moderated by attentional abilities. Such findings suggest that different age groups may use looking differently, and this may reflect their preferences for using distinct emotion regulatory strategies. This work also serves as a reminder that regulatory efforts are not always successful at improving mood. 相似文献
