A decentralized computer network for supervision of multiple psychological laboratories

The computer network described was designed to optimize the use of a number of independent minicomputers as a single integrated system for process control of several research laboratories. The implementation of the network required both the development of a special purpose interprocessor interface and the design of a software support system to direct network operations. The network was designed according to the familiar “star” configuration, with the exception that the central computer in the star does not exercise exclusive supervisory control over the system. Rather, each computer on the system “sees” the central computer as a peripheral similar in characteristics to a medium speed I/O device. This design allows each computer to serve not only as a node in the network, but also as an entirely independent process controller.

Constitutivism and Inescapability: A Diagnosis

A central element of constitutivist accounts of categorical normativity is the claim that the ultimate foundation of the relevant kind of practical authority is sourced in certain tasks, features, and aims that every person inevitably possesses and inescapably has to deal with. We have no choice but to be agents and this fact is responsible for the norms and principles that condition our agency-related activities to have anunconditional normative grip on us. Critics of constitutivism argue that it is exactly because of itsinescapability that agency is a powerless source of normative authority. I investigate why our intuitionsconcerning the appeal to inescapability point into such contrary directions. Why do we feel the attraction ofgrounding categorical normativity in phenomena that not even the skeptic can ignore, on the one hand, butseem to hold dear the principle that “ought implies need not,” on the other? Instead of fully developing thethird, neutral, way of conceptualizing the relationship between inescapability and normativity that theimpasse between constitutivists and their critics suggests, this paper diagnoses the disagreement at hand.That agency is inescapable does neither guarantee nor rule out its status qua source of categoricalnormativity. Both camps of the debate overlook this option and depict their opponents as adhering to animplausible perspective of how appeals to inescapability and unconditional normativity are related. Sincethe debate relies on a false dichotomy it is not surprising that its participants so often talk past each other.     

Visual perspective in remembering and episodic future thought

According to the constructive episodic simulation hypothesis, remembering and episodic future thinking are supported by a common set of constructive processes. In the present study, we directly addressed this assertion in the context of third-person perspectives that arise during remembering and episodic future thought. Specifically, we examined the frequency with which participants remembered past events or imagined future events from third-person perspectives. We also examined the different viewpoints from which third-person perspective events were remembered or imagined. Although future events were somewhat more likely to be imagined from a third-person perspective, the spatial viewpoint distributions of third-person perspectives characterizing remembered and imagined events were highly similar. These results suggest that a similar constructive mechanism may be at work when people remember events from a perspective that could not have been experienced in the past and when they imagine events from a perspective that could not be experienced in the future. The findings are discussed in terms of their consistency with—and as extensions of—the constructive episodic simulation hypothesis.     

Negation in context: Evidence from the visual world paradigm

Literature assumes that negation is more difficult to understand than affirmation, but this might depend on the pragmatic context. The goal of this paper is to show that pragmatic knowledge modulates the unfolding processing of negation due to the previous activation of the negated situation. To test this, we used the visual world paradigm. In this task, we presented affirmative (e.g., her dad was rich) and negative sentences (e.g., her dad was not poor) while viewing two images of the affirmed and denied entities. The critical sentence in each item was preceded by one of three types of contexts: an inconsistent context (e.g., She supposed that her dad had little savings) that activates the negated situation (a poor man), a consistent context (e.g., She supposed that her dad had enough savings) that activates the actual situation (a rich man), or a neutral context (e.g., her dad lived on the other side of town) that activates neither of the two models previously suggested. The results corroborated our hypothesis. Pragmatics is implicated in the unfolding processing of negation. We found an increase in fixations on the target compared to the baseline for negative sentences at 800?ms in the neutral context, 600?ms in the inconsistent context, and 1450?ms in the consistent context. Thus, when the negated situation has been previously introduced via an inconsistent context, negation is facilitated.
