For example, Olson and Olson (1999) observe that it appears that information must be held by at least two people in the group before it will be brought to the attention of the group as a whole (p. 419).

A possible reason for this is that information held by a single individual may lack adequate social validation (for) the value or accuracy of the information (Hinsz et al., 1997, p. 47).

On the other hand, in open source the process is intentionally kept public and transparent. The norms are against private discussions. As Fogel (2005) observes, As slow and cumbersome as public discussions can be, they re almost always preferable in the long run.

Making important decisions in private is like spraying contributor repellant on your project. In terms of their general propensities, collaborating groups will tend to share information better if the group perceives that there is a single correct solution to a task. Research differs as to whether the encoded representations of information by groups are more or less complex than those of individuals.

Differences in such mental representations among members can lead to con icts whose causes may not even be evident until after group discussion. Groups tend to be superior to individuals in terms of their ability to store and retrieve information, the greater reliability of retrieval being due to the group s ability to correct faulty individual memories. Obviously in computer-supported groups and open source projects there are extensive mechanisms for institutional memory ranging from e-mail archives to CVS repositories that can readily reproduce any previous state of a project and the logged rationales for modi cations.

The response of groups is also affected by consensus rules. For example, if a majority vote rather than merely a unanimous one decides an issue, then groups show greater exibility in moving away from an alternative they had previously accepted. We have previously observed how the IETF (Internet Engineering Task Force) development structure, based on the motto of rough consensus and working code, informed the process and voting model for key open projects like Apache (Moody, 2001).

For certain kinds of open development issues, like whether a given interface seems appropriate, nonbinding polls of broader populations of user-participants can be used to guide consensus. Groups generally appear to use information-processing rules or strategies more reliably and consistently (p. 50) than individuals, though this does not necessarily correlate with correctness, just with consistency.

A consistently recognizable pattern in group processing is that groups generally decrease variability in the way information is processed, compared with individuals (p. 53), including narrowed focus of attention, redundant memories, accentuation of processing strategies, and shared distribution of information (p. 53).

Hinsz et al. (1997) also consider the so-called combination of contributions model for small-group collaboration, a model which supplements their own view of groups as information. 5.6 Cognitive Psychology and Open Source processors. S Software QR Code 2d barcode ome of the issues that arise from the viewpoint of the latter combinations model are how to identify the resources, skills, and knowledge that members bring to an interaction and what processes are involved in combining or transforming those individual contributions to produce the group outcome. In the case of open projects, the core developer group tends to be relatively small and so the individual strengths of their members are well known to one another, which is in fact one reason for the low bureaucratic overhead of these groups.

The application of cognitive psychology to the analysis of group collaboration has sometimes been criticized for paying inadequate attention to both the social and the physical context of collaboration (Olson and Olson, 1999). The emerging eld of distributed cognition represents an attempt to remedy this by characterizing cognitive processes not only in terms of activity inside the heads of individuals but in the patterns of activity across individuals and in the material artifacts that mediate this activity (p. 418).

In distributed cognition, the social setting and the artifacts (p. 418) include processes like those that support short-term memory, such as having someone remind us what we were talking about prior to an interruption occurring, or that support long-term memory, like remembering who else knows something so that we do not have to commit it to memory or artifacts like paper-and-pencil calculation to facilitate processing. The Olson s claim that the most important implication of the theory of distributed cognition is that we can design the artifacts and the social processes to embody cognition .

419). Obviously in open software development the ultimate artifact is the code, as well as the descriptions of the problems to address and the rationales for solutions. The simple exchange of program source code during development via the FTP network protocol was one of the earliest advances in exchanging design artifacts.

The introduction of CVS during the late 1980s and early 1990s together with the Internet accessibility of the CVS repositories represents the embodiment of the distributed cognition underlying open source development..
