Punishment of an alternative behavior generates resurgence of a previously extinguished target behavior

Resurgence is often defined as the recurrence of an extinguished behavior when a more recently reinforced alternative behavior is also extinguished. Resurgence has also been observed when the alternative behavior is devalued by other means (e.g., reinforcement rate or magnitude reductions). The present study investigated whether punishment of an alternative behavior would generate resurgence. A target response was reinforced during Phase 1 and then extinguished in Phase 2 while an alternative response was reinforced. During Phase 3, response‐dependent foot shocks were superimposed on the schedule of reinforcement for the alternative response and shock intensity was escalated gradually across sessions. Resurgence of the target response was reliably observed, mostly at higher intensities. The effect was replicated in two subsequent exposures to the sequence of conditions, with resurgence tending to occur at the lowest foot shock intensity. These results suggest that devaluation of an alternative behavior via punishment can generate resurgence. Although it is difficult to reconcile the overall pattern of results with Bouton's context account, these findings are consistent with the suggestion that resurgence results from a “worsening of conditions” for the alternative behavior and with the formalization of that suggestion in terms of a choice‐based matching‐law account (i.e., Resurgence as Choice).     

Ethics in Transnational Forensic DNA Data Exchange in the EU: Constructing Boundaries and Managing Controversies

Under EU Law, Member States are compelled to engage in reciprocal automated forensic DNA profile exchange for stepping up on cross-border cooperation, particularly in combating terrorism and cross-border crime. The ethical implications of this transnational DNA data exchange are paramount. Exploring what the concept of ethics means to forensic practitioners actively involved in transnational DNA data exchange allows discussing how ethics can be addressed as embedded in the sociality of science and in the way scientific work is legitimated. The narratives of forensic practitioners juxtapose the construction of fluid ethical boundary work between science and non-science with the dynamic management of controversies, both of which are seen as ways to lend legitimacy and objectivity to scientific work.

Ethical boundary work involves diverse fluid forms: as a boundary between science/ethics, science/criminal justice system, and good and bad science. The management of controversies occurs in three interrelated ways. First, through a continuous process of reconstructing delegations of responsibility in dealing with uncertainty surrounding the reliability of DNA evidence. Second, threats to the protection of data are portrayed as being resolved by black-boxing privacy. Finally, controversies related to social accountability and transparency are negotiated through the lens of opening science to the public.

Nuclear Power is Neither Right Nor Wrong: The Case for a Tertium Datur in the Ethics of Technology

The debate over the civilian use of nuclear power is highly polarised. We argue that a reasonable response to this deep disagreement is to maintain that advocates of both camps should modify their positions. According to the analysis we propose, nuclear power is neither entirely right nor entirely wrong, but rather right and wrong to some degree. We are aware that this non-binary analysis of nuclear power is controversial from a theoretical point of view. Utilitarians, Kantians, and other moral theorists make sharp, binary distinctions between right and wrong acts. However, an important argument speaking in favour of our non-binary analysis is that it better reflects our considered intuitions about the ethical trade-offs we face in discussions of nuclear power. The aim of this article is to make this argument sharp by explaining how it can be rendered compatible with, and supported by, the Capability Approach, which is quickly becoming one of the most influential frameworks for thinking about human development.     

Effect of stimulus opening size in global dominance with orientation classification task

The aims of this study is to examine whether global dominance depends on the opening size of the stimulus with concentric hierarchical figures and orientation classification task and to determine the role of the salience of global opening and its coincidence with vertical symmetry axis of context. In the first experiment, participants had to indicate the opening direction of stimuli, which were open-left and open-right figures. Three openings were included: 10, 25 and 50% of the total circle perimeter. The results showed a local advantage with stimuli of 10%, absence of global or local advantage with stimuli of 25% and global advantage with stimuli of 50%. In the second experiment, stimuli with an opening of 50% were presented randomly in several positions in the visual field in order to avoid the coincidence of global opening with the vertical symmetry axis of context. The results showed an absence of global or local advantage. These findings indicate that global dominance with orientation classification task depends on stimulus characteristics such as opening size, and strategies used in visual recognition.     

Effect of the similarity between target and global and local levels in hierarchical stimuli processing

The hypothesis of global precedence was investigated by manipulating the similarity between target and relevant level, and between target and global and local levels of hierarchical stimuli, both in divided and selective attention conditions. The similarity was measured on the basis of the amount of shared contour between two visual forms. The stimuli were circles, right-facing semicircles, i.e., 1/2 of the circumference missing, and right-facing partial circles with a 1/4 of the circumference missing. The circle was used as a target and, consequently, the similarity between target and semicircle and between it and the partial circle was 50% and 75%, respectively. In the divided attention condition, the results showed a local advantage in the two similarity conditions between target and distractor level (50% and 75%) and a bidirectional and symmetrical interference at both levels of similarity. However, in the 'selective attention condition', a local reaction time advantage was only found when the similarity between target and irrelevant level was of 50%. When attention was directed towards the global level, local interference increased depending on the decrease in the degree of the local level similarity. When the attention was directed towards the local level, there was global interference but it was independent of the degree of the global level similarity. These results show the importance of the physical shape of the local elements used in experiments with hierarchical stimuli, since they may determine the relative speed of global processing, facilitating or impairing it.     

An Invitation to Travel in an Interethnic Arena: Listening Carefully to Amerindian Leaders’ Speeches

In this article, we identify usual difficulties faced by Brazilian psychologists when dealing with Amerindian Peoples, concerning the systematic violence experienced by those Peoples, who have been suffering and fighting against a process of genocide and ethnocide. To identify those difficulties, we analysed speeches of Amerindian leaders of the State of São Paulo - Guarani Mbya, Pankararu, Xavante, Baniwa, Tupi - Guarani, Terena, Kaingang and Krenak - which were addressed to psychologists. Those speeches were delivered in events promoted by CRP-SP in 2010 and in the 2nd and 3rd Forums “The Amerindian presence in São Paulo” at the Institute of Psychology (USP), in 2014. From the analysis, we make a distinction between the notions of meeting and dialogical encounter, considering that: 1. not every meeting is an encounter, in the dialogical sense, because the meeting can happen in a way that one of the interlocutors is objectified by the other and 2. being together and building an affective ground is an a priori for the dialogical encounter to happen. Based on the leaderships` speeches and in the notions of Amerindian perspectivism and the phenomenology of alterity in Cultural Psychology, we propose alternative paths to understand constitutive aspects of a dialogical meeting in such interethnic situation. These reflections are proposed as a theoretic-empirical work, as it departs from the comprehension that the theoretical problems are not separated from the concrete situation that enables them to emerge.     

Narrative Skills in Written Texts by Deaf and Hearing Bilingual Adolescents

Most studies on narrative competence have focused on monolingual subjects, and there are very few studies which address this issue in bilingual subjects dealing with two language systems. In the present case study we analyzed and compared the textual and narrative written skills of three deaf and three hearing adolescents attending eighth grade at a bilingual school (Italian and Italian Sign Language), characterized by a pragmatic approach to writing (based on production and the interpretation of texts in genuine and meaningful situations).Their competences were assessed through a well-known narrative task, the Frog Story (Mayer, 1969), and the following parameters were examined: complex syntax, narrative structure and evaluation devices. Results show that there were not significant differences in the texts written by the deaf students compared to the hearing students and that being immersed in a bilingual context did not interfere with the development of textual and narrative competence in either hearing or deaf students.
