The paradox of the universal triangle: Concepts,language, and prototypes

For over 300 years, the humble triangle has served as the paradigmatic example of the problem of abstraction. How can we have the idea of a general triangle even though every experience with triangles is with specific ones? Classical cognitive science seemed to provide an answer in symbolic representation. With its easily enumerated necessary and sufficient conditions, the triangle would appear to be an ideal candidate for being represented in a symbolic form. I show that it is not. Across a variety of tasks—drawing, speeded recognition, unspeeded visual judgments, and inference—representations of triangles appear to be graded and context dependent. I show that using the category name “triangle” activates a more prototypical representation than using an arguably coextensive cue, “three-sided polygon”. For example, when asked to draw “triangles” people draw more typical triangles than when asked to draw “three-sided polygons”. Altogether, the results support the view that (even formal) concepts have a graded and flexible structure, which takes on a more prototypical and stable form when activated by category labels.     

When criticism is ineffective: The case of historical trauma and unsupportive allies

Three studies examined the effect of historical trauma reminders and criticism from international allies on attitudes toward current conflicts. In Study 1, Israeli participants (N = 116) were primed with the Holocaust, and read either that the U.S. President Obama supports Israel's right to defend itself and attack Iran, or that he opposes such action. Then, support for preemptive violence was assessed. Study 2 (N = 133) replicated this design, comparing inclusive and exclusive framings of the Holocaust. Study 3 (N = 478), examined the effect of Holocaust reminders and criticism from the European Union on attitudes toward militant policies against Palestinians. All three studies found that Holocaust primes juxtaposed with international criticism increased support for aggression, especially under exclusive framings of the Holocaust. Study 3, however, found this effect only among left‐wing participants. These findings indicate that when historical trauma is salient, international criticism may be ineffective and may even backfire.     

Ecobiopsychology

The latest scientific discoveries acknowledge that the universe, from the atom to the galaxies, is a system behaving as a whole where each single set composing it seems informed by the global state of the system. In-formation can be exemplified as a “software” governing the “hardware” that is composed of the objects of the universe. This in formation comes from an Akashic Field or archetypal field that can breed each single form as well as the relevant states of consciousness. Ecobiopsychology, through the study of vital analogies and symbols, supports reflective consciousness to have access to the archetypal field studying the relation between the aspects of matter (infrared) and those referred to the psyche (ultraviolet). With this perspective the human's reflective consciousness field can gradually expand until becoming accessible to the reality of the Unus Mundus, represented by the coherence of the single structures of the universe and their own embedded state of implicit consciousness.     

The fate of completed intentions

The goal of this research was to determine whether and how people deactivate prospective memory (PM) intentions after they have been completed. One view proposes that PM intentions can be deactivated after completion, such that they no longer come to mind and interfere with current tasks. Another view is that now irrelevant completed PM intentions exhibit persisting activation, and continue to be retrieved. In Experiment 1, participants were given a PM intention embedded within the ongoing task during Phase 1, after which participants were told either that the PM task had been completed or suspended until later. During Phase 2, participants were instructed to perform only the ongoing task and were periodically prompted to report their thoughts. Critically, the PM targets from Phase 1 reappeared in Phase 2. All of our measures, including thoughts reported about the PM task, supported the existence of persisting activation. In Experiment 2, we varied conditions that were expected to mitigate persisting activation. Despite our best attempts to promote deactivation, we found evidence for the persistence of spontaneous retrieval in all groups after intentions were completed. The theoretical and practical implications of this potential dark side to spontaneous retrieval are discussed.     

Accessibility and characteristics of memories of the future

Recent research suggests that some imagined future events are encoded in memory, leading to the formation of “memories of the future”. However, questions remain regarding the exact components of future event simulations that are encoded and the factors that determine their accessibility. To address these questions, the present study investigated memory for previously imagined future events using both free and cued recall tasks. The results showed that most future event simulations were successfully encoded and remained available in memory after a one week delay, but only some of them were readily accessible, whereas others could only be accessed when relevant cues were provided. Persons and locations were particularly well remembered, suggesting that these components are central to the simulation and memorisation of future events. We also found that memory for future event simulations was related to the clarity and familiarity of represented persons, the subjective feelings of pre-experience and mental time travel, the importance of imagined events to personal goals, and their emotional intensity during the initial simulation phase. Taken together, these findings expand our understanding of the formation, accessibility, and characteristics of memories of the future.     

Dewey’s Social Ontology: A Pragmatist Alternative to Searle’s Approach to Social Reality

Dewey’s social ontology could be characterized as a habit ontology, an ontology of habit qua second nature that offers us an account of intentionality, social statuses, institutions and norms in terms of habituations. Such an account offers us a promising alternative to contemporary intentionalist and deontic approaches to social ontology such as Searle’s. Furthermore, it could be the basis of a social ontology better suited to explain both the maintenance and the transformation of social reality.     

Does goal relevant episodic future thinking amplify the effect on delay discounting?

Delay discounting (DD) is the preference for smaller immediate rewards over larger delayed rewards. Research shows episodic future thinking (EFT), or mentally simulating future experiences, reframes the choice between small immediate and larger delayed rewards, and can reduce DD. Only general EFT has been studied, whereby people reframe decisions in terms of non-goal related future events. Since future thinking is often goal-oriented and leads to greater activation of brain regions involved in prospection, goal-oriented EFT may be associated with greater reductions in DD than general goal-unrelated EFT. The present study (n = 104, M_age = 22.25, SD = 3.42; 50% Female) used a between-subjects 2 × 2 factorial design with type of episodic thinking (Goal, General) and temporal perspective (Episodic future versus recent thinking; EFT vs ERT) as between factors. Results showed a significant reduction in DD for EFT groups (p < 0.001, Cohen’s d effect size = 0.89), and goal-EFT was more effective than general-EFT on reducing DD (p = 0.03, d = 0.64).     

THE COLLECTIVIST APPROACH TO COLLECTIVE MORAL RESPONSIBILITY

Abstract: In this article we critique the collectivist approach to collective moral responsibility. According to philosophers of a collectivist persuasion, a central notion of collective moral responsibility is moral responsibility assigned to a collective as a single entity. In our critique, we proceed by way of discussing the accounts and arguments of three prominent representatives of the collectivist approach with respect to collective responsibility: Margaret Gilbert, Russell Hardin, and Philip Pettit. Our aims are mainly critical; however, this should not be taken to imply that we do not ourselves support an alternative account of collective responsibility. We advocate an individualist account of collective responsibility. On this view of collective responsibility as joint responsibility, collective responsibility is ascribed to individuals. Each member of the group is individually morally responsible for the outcome of the joint action, but each is individually responsible jointly with the others.

Global Justice for Humans or for all Living beings and what Difference it Makes

I begin with an account of what is deserved in human ethics, an ethics that assumes without argument that only humans, or rational agents, count morally. I then take up the question of whether nonhuman living beings are also deserving and answer it in the affirmative. Having established that all individual living beings, as well as ecosystems, are deserving, I go on to establish what it is that they deserve and then compare the requirements of global justice when only humans are taken into account with the requirements of global justice when all living beings are taken into account.
