Evaluating treatment effects in single-subject behavioral experiments using quality-control charts

Quality-control charts can be particularly useful in identifying treatment effects and patterns of behaviors in single-subject behavior-analytic experiments that cannot be determined by visual inspection of their graphs. Using an example from the behavior analysis literature the quality-control charts identified the presence of treatment effects across phases as well as the presence of trends within and between phases. The ease of their calculations suggest use of them by behavior analysts whenever the effects of particular interventions are questionable.     

Integration processes during frequency graph comprehension: Performance and eye movements while processing tree maps versus pie charts

Frequency graph types differ in the way how data are translated into visual representations. We compared 2 visualization methods, a traditional circular representation (pie chart) and a rectangular representation (constant column width tree map), which were hypothesized to differ regarding the cognitive ease of visual comparison processes. Performance was evaluated in tasks involving proportion and comparison judgments under both highly controlled and more realistic circumstances. The results showed performance benefits (in terms of reduced response times or error rates) for rectangular representations. Additional eye movement analyses revealed that this benefit was mainly due to a facilitation of scanning the graph for relevant information. The results suggest that facilitating comparison processes by representing the critical variable in less complex visual dimensions (i.e., straight length with constant orientation instead of surface area or curved length) eventually enhances the efficiency of integration processes during graph comprehension.

Initial perceptions in negotiations: evaluation and response to ‘logrolling’ offers

In negotiations, where several issues are under consideration and parties have different priorities among these issues, integrative agreements can be reached through ‘logrolling’: concessions on low priority issues in exchange for gains on higher priority issues. The present research focuses on the potential role of initial offers in the development of integrative agreements. We show first, that in a simulated competitive market the specific composition of initial offers influences the final agreements, beyond the effect predicted by their overall value. In order to obtain some insight into the judgmental processes that might play a role, we explore the way in which inexperienced negotiators presented with a hypothetical negotiation context evaluate and respond to logrolling versus distributive initial offers. Three hypotheses were tested: logrolling offers convey an implicit message of cooperation, logrolling offers promote understanding of the mutual interest structure of the task, and, finally, logrolling offers establish within‐issue anchors. Results do not support the first two hypotheses: logrolling offers were not necessarily judged more attractive than distributive ones, and they did not seem to affect the deeply rooted fixed‐pie assumption. However, initial offers did establish within‐issue anchors: counter‐offers were affected by the specific composition of the initial offers beyond the effect of their overall value. This anchoring process resulted in logrolling offers yielding a higher profit for their initiator, as well as higher combined profits for both parties. Copyright © 2002 John Wiley & Sons, Ltd.     

The computational complexity of scenario-based agent verification and design

We first advocate that the AUML (Agent Unified Modeling Language) notation, even in its new version, is not precise enough to adequately describe protocols. This problem was long identified by Harel and we propose to follow his solution: extend sequence diagrams with a “prechart”, i.e. single out the initiation sequence of the protocol. This new notation keeps readability and intuition, but is also technically adequate and is given a formal semantics. It actually is a form of simple temporal logics, equipped with a game-based semantics, which is appropriate for modeling agent-based systems. We then go on to study its complexity. Unsurprisingly, the version with protocol roles is undecidable. The main interesting problem is to synthesize agents that follow the protocol described. Surprisingly, it is undecidable even if we remove roles, alternatives, loops, asynchronous communication, conditions, constraints, negations (already removed in AUML). The complexity of checking whether a society of agents obeys a protocol given in this trivial notation is also surprisingly high: it is PSPACE-complete, like temporal logic, while we show that this simple language is strongly less expressive than temporal logic. Notations in-between have the expected increase in expressiveness, but no increase in complexity. This justifies the use of a language including alternatives, asynchronous communication and conditions, since it increases expressiveness with no cost in complexity.     

Goal orientations in negotiations: the influence of goal orientations on fixed-pie perceptions and bargaining outcomes

As is the case for other achievement situations, people may approach negotiations emphasizing outcome and/or process goals. This paper examines the effects of process goal orientation (PGO) and outcome goal orientation (OGO) on individuals' fixed-pie perceptions and the negotiation of joint outcomes. Process and outcome goal orientations are associated with different personal beliefs about the world. We hypothesized that persons who are primarily oriented toward outcome goals, based on their fixed-entity perception of the world, would mainly concentrate on the final results or on the outcomes of the negotiation. They would tend to perceive negotiations as fixed, zero-sum, competitive situations, which have to be "won" by one of the parties at the expense of the other. On the other hand, we predicted that people who are strongly process-oriented, based on their malleable-entity perception of the world, would focus mainly on formulating and mastering the best strategies that lead to successful resolution of the negotiation. They would perceive positions to be "malleable" and, hence, would tend to perceive the negotiation as a non zero-sum situation. Additionally, the interaction between the two types of goal orientations and its effect on the parties' joint negotiation outcomes was examined. Results of two empirical studies indicated that OGO was significantly positively associated with fixed-pie bias (Study 1). The significant interaction between PGO and OGO (Study 2) demonstrated that a strong OGO combined with a strong PGO led to the best joint negotiation outcomes. Implications for goal orientation and negotiation theories are discussed.     

买卖交易中谈判者角色影响谈判结果的机制

现实生活中的谈判通常发生在特定的社会情境中, 谈判者也总在扮演着某种角色。本研究探索了买卖交易谈判中谈判者角色影响谈判结果的作用机制。研究提出了一个关于谈判者角色诱发框架效应的理论模型, 然后通过两个模拟谈判实验对这一模型进行验证。实验1表明, 买家知觉到的馅饼大于卖家知觉到的馅饼, 且谈判者知觉到的馅饼在谈判者角色与谈判者绩效间起部分中介作用。实验2发现, 即使保留买家与卖家的角色标签, 如果剥离了金钱作为交易介质这一重要特征, 两个谈判角色知觉到的馅饼也没有差异。研究揭示了谈判者角色影响谈判结果的作用机制, 对谈判者如何利用情境因素取得更好的谈判结果具有实践意义。
