Iterated Belief Revision and Conditional Logic

In this paper we propose a conditional logic called IBC to represent iterated belief revision systems. We propose a set of postulates for iterated revision which are a small variant of Darwiche and Pearl's ones. The conditional logic IBC has a standard semantics in terms of selection function models and provides a natural representation of epistemic states. We establish a correspondence between iterated belief revision systems and IBC-models. Our representation theorem does not entail Gärdenfors' Triviality Result.     

A comparative analysis of global and local processing of hierarchical visual stimuli in young children (Homo sapiens) and monkeys (Cebus apella)

Results obtained with preschool children (Homo sapiens) were compared with results previously obtained from capuchin monkeys (Cebus apella) in matching-to-sample tasks featuring hierarchical visual stimuli. In Experiment 1, monkeys, in contrast with children, showed an advantage in matching the stimuli on the basis of their local features. These results were replicated in a 2nd experiment in which control trials enabled the authors to rule out that children used spurious cues to solve the matching task. In a 3rd experiment featuring conditions in which the density of the stimuli was manipulated, monkeys' accuracy in the processing of the global shape of the stimuli was negatively affected by the separation of the local elements, whereas children's performance was robust across testing conditions. Children's response latencies revealed a global precedence in the 2nd and 3rd experiments. These results show differences in the processing of hierarchical stimuli by humans and monkeys that emerge early during childhood.     

The imaginer and the imagined

A transference of the imaginer and the imagined, arising from largely unconscious fantasies of the way parent and child interact to construct a view of reality, is present in all analyses. For narcissistic patients, primitive fantasies of the imaginer and imagined form an enduring organization, and the enactment of these fantasies in transference and countertransference distorts the way analyst and patient construct meaning. Clinical material demonstrates the deepening that occurs when these fantasies are interpreted.     

Apraxia is not associated to a disproportionate naming impairment for manipulable objects

The relevance of gesture knowledge for the semantic representation of manipulable objects was investigated in a series of 15 patients with a focal left-hemisphere lesion. The patients were classified according to the presence/absence of ideomotor and ideational apraxia. We investigated picture naming and word-picture matching (pointing to a picture on verbal command) with stimuli including items from three categories: manipulable objects, non-manipulable objects, and animals. The analysis was performed at group level and at single-patient level. Nine patients were affected by ideational apraxia and nine by ideomotor apraxia: two cases presented ideomotor but not ideational apraxia, and two cases presented the opposite dissociation. Patients affected by ideational apraxia were more severely impaired in all tasks, but did not show a disproportionate impairment with the category of manipulable objects in contrast to the other categories. The presence of ideomotor apraxia did not cause a greater impairment in any task or category. Finally, we observed a patient with ideational apraxia who performed flawlessly in naming and word-picture matching for all the stimuli, including manipulable objects. In conclusion, we did not find a relationship between ideational apraxia and a disproportionate impairment of the semantic knowledge of manipulable objects.     

Global and local processing of hierarchical visual stimuli in tufted capuchin monkeys (Cebus apella)

Capuchin monkeys' (Cebas apella) relative accuracy in the processing of the global shape or the local features of hierarchical visual stimuli was assessed. Three experiments are presented featuring manipulations of the arrangement and the density of the local elements of the stimuli. The results showed a clear advantage for local level processing in this species, which is robust under manipulations of the density of the local elements of the stimuli. By contrast the density of the component elements linearly affected accuracy in global processing. These findings, which support those from other studies in which a local superiority emerged in animals, challenge the generality of early claims concerning the adaptive value of global advantage in the processing of hierarchical visual patterns.     

Strategic aspects of numerosity judgment: the effect of task characteristics

In previous investigations we documented that people use several strategies to determine different numerosities of blocks that are presented in a square grid. One of these strategies is the clever subtraction strategy, wherein the number of empty squares in the grid is subtracted from the total number of squares in the grid. In the present study we investigated participants' flexibility in strategy use when varying the shape of the grid. Analysis of the results in terms of the theoretical framework of Lemaire and Siegler (1995) regarding strategic change shows that this contextual variable affected the frequency, execution time, and accuracy of subjects' use of the subtraction strategy. The usefulness of this framework for analyzing the nature of the adaptation to contextual variations is discussed. From a methodological point of view, this study documents the potential of Beem's (1993, 1999) segmented linear regression models for assessing subjects' strategy use in cognitive tasks.     

A satisfied clientele seeking more diverse services: Latinos and the courts

This article assesses Latino views of the court system, both of their beliefs about the courts and their experiences with the courts. Relying primarily on the Latino over-sample of the National Center for State Courts (2000) survey of public attitudes toward the courts, we evaluate three aspects of the Latino-judicial relationship. First, we measure whether there are differences between Latino and non-Latino views of the courts. Second, we assess whether there are differences within the Latino community, particularly differences based on nativity, in Latino attitudes toward the courts. Finally, we assess the implications of Latino views of the courts for US society in general. We are particularly concerned about whether having a greater share of Latinos in the population will create new pressures to reform the judiciary.
