Two experiments investigated list-method directed forgetting with older and younger adults. Using standard directed forgetting instructions, significant forgetting was obtained with younger but not older adults. However, in Experiment 1 older adults showed forgetting with an experimenter-provided strategy that induced a mental context change--specifically, engaging in diversionary thought. Expe...

In this paper, we present an approach to forgetting in disjunctive logic programs, where forgetting an atom from a program amounts to a reduction in the signature of that program. Notably, the approach is syntax-independent, so that if two programs are strongly equivalent, then the result of forgetting a given atom in each program is also strongly equivalent. Our central definition of forgettin...

The ability to control how we process information by remembering that which is important and forgetting that which is irrelevant is essential to maintain accurate, up-to-date memories. As such, memory success is predicated on both successful intentional encoding and successful intentional forgetting. The current study used an item-method directed forgetting paradigm to elucidate the cognitive a...

A new method is described for determining the effect of original learning (or any other variable) on forgetting. The major question is, How much forgetting time is required for memory performance to fall from any given level to some lower level? If this time is the same for different degrees of original learning, then forgetting is not affected by degree of original learning. If this time is gr...

The ability of discarding or hiding irrelevant information has been recognized as an important feature for knowledge based systems, including answer set programming. The notion of strong equivalence in answer set programming plays an important role for different problems as it gives rise to a substitution principle and amounts to knowledge equivalence of logic programs. In this paper, we unifor...

In this paper we study a formal notion of knowledge forgetting in S5 modal logic. We propose four postulates and prove that these postulates precisely characterize both semantic and logical properties of knowledge forgetting. We then investigate possible applications of knowledge forgetting in various epistemic reasoning scenarios. In particular, we show that different forms of knowledge update...

Purpose The purpose of this paper is to advance knowledge organizational change towards diversity by bringing together concepts from learning and studies. Design/methodology/approach This longitudinal study was conducted over two years. It involved interviews, observation meetings consultation documentation the analysis focused on learning. key research question how do members institutionalize ...

Forgetting is a universal feature for most types of memories. The best-defined and extensively characterized behaviors that depict forgetting are natural memory decay and interference-based forgetting [1, 2]. Molecular mechanisms underlying the active forgetting remain to be determined for memories in vertebrates. Recent progress has begun to unravel such mechanisms underlying the active forget...

In this paper, we propose two new and different approaches to forgetting variables for ALC based on the well-known tableau algorithm. The first approach computes the result of forgetting via rolling up tableaux, which also provides insights of the decidability of existence of forgetting inALC . When the result of forgetting does not exist, we provide an incremental method for computing approxim...
