In these visuo-motor experiments, the outcome of a hand or eye movement is associated with explicit gains and losses (see, e.g. [1]). The results obtained from these studies indicate that human participants typically select surprisingly efficient strategies that come close to maximizing expected gain. For example, under conditions in which the end point variance of speeded hand movements is artificially increased by perturbing the final finger position, humans quickly generate a representation of their modified end point variance and rely on this representation in planning their movements so as to maximize gain [2]. Furthermore, human subjects have been found to implicitly learn the stochasticity of spatially stochastic rewards and losses in only a few hundred trials [3]. These results indicate that humans are able to implicitly estimate the parameters of noisy movement outcomes and of stochastic environmental variables and can use this knowledge to plan their hand movements such as to maximize expected gain. A comparison of performance across these tasks indicates that knowledge about movement uncertainty is learnt within fewer trials than knowledge about the uncertainty in the final target position. This suggests that visual feedback about the hand position is processed and integrated by different mechanisms than visual information about the final target position.","PeriodicalId":89381,"journal":{"name":"IEEE International Conference on Development and Learning : [proceedings].

Pluggable types blur this division by (i) making static type systems optional, and (ii) supporting a choice of type systems for reasoning about different kinds of static properties. Dynamic languages can then benefit from static-checking without sacrificing dynamic features or committing to a unique, static type system. But the overhead of adopting pluggable types can be very high, especially if all existing code must be decorated with type annotations before any type-checking can be performed. We propose a practical and pragmatic approach to introduce pluggable type systems to dynamic languages. First of all, only annotated code is type-checked. Second, limited type inference is performed on unannotated code to reduce the number of reported errors. Finally, external annotations can be used to type third-party code. We present TypePlug, a Smalltalk implementation of our framework, and report on experience applying the framework to three different pluggable type systems.","PeriodicalId":89381,"journal":{"name":"IEEE International Conference on Development and Learning : [proceedings].

Most programming languages and development environments, however, are more concerned with limiting the effects of change rather than enabling and exploiting change. Various techniques and technologies to exploit change have been developed over the years, but there exists no common support for these approaches. We propose Changeboxes as a general-purpose mechanism for encapsulating change as a first-class entity in a running software system. Changeboxes support multiple, concurrent and possibly inconsistent views of software artifacts within the same running system. Since Changeboxes are first-class, they can be manipulated to control the scope of change in a running system. Furthermore, Changeboxes capture the semantics of change. Changeboxes can be used, for example, to encapsulate refactorings, or to replay or analyze the history of changes. In this paper we introduce Changeboxes by means of a prototype implementation. We illustrate the benefits that Changeboxes offer for evolving software systems, and we present the results of a preliminary performance evaluation that assesses the costs associated with Changeboxes while suggesting possible strategies for improvement.","PeriodicalId":89381,"journal":{"name":"IEEE International Conference on Development and Learning : [proceedings].

From a structural perspective it is difficult to gain an understanding of how source entities participate in a system's features at runtime, especially when using dynamic languages such as Smalltalk. In this paper we evaluate the usefulness of offering an alternative, complementary feature-centric perspective of a software system when performing maintenance activities. We present a feature-centric environment combining interactive visual representations of features with a source code browser displaying only the classes and methods participating in a feature under investigation. To validate the usefulness of our feature-centric view, we conducted a controlled empirical experiment where we measured and compared the performance of subjects when correcting two defects in an unfamiliar software system with a traditional development environment and with our feature-centric environment. We evaluate both quantitative and qualitative data to draw conclusions about the usefulness of a feature-centric perspective to support program comprehension during maintenance activities.","PeriodicalId":89381,"journal":{"name":"IEEE International Conference on Development and Learning : [proceedings].
