Relative speed of processing determines color–word contingency learning

In three experiments, we tested a relative-speed-of-processing account of color–word contingency learning, a phenomenon in which color identification responses to high-contingency stimuli (words that appear most often in particular colors) are faster than those to low-contingency stimuli. Experiment 1 showed equally large contingency-learning effects whether responding was to the colors or to the words, likely due to slow responding to both dimensions because of the unfamiliar mapping required by the key press responses. For Experiment 2, participants switched to vocal responding, in which reading words is considerably faster than naming colors, and we obtained a contingency-learning effect only for color naming, the slower dimension. In Experiment 3, previewing the color information resulted in a reduced contingency-learning effect for color naming, but it enhanced the contingency-learning effect for word reading. These results are all consistent with contingency learning influencing performance only when the nominally irrelevant feature is faster to process than the relevant feature, and therefore are entirely in accord with a relative-speed-of-processing explanation.     

Are some negotiators better than others? Individual differences in bargaining outcomes

The authors address the long-standing mystery of stable individual differences in negotiation performance, on which intuition and conventional wisdom have clashed with inconsistent empirical findings. The present study used the Social Relations Model to examine individual differences directly via consistency in performance across multiple negotiations and to disentangle the roles of both parties within these inherently dyadic interactions. Individual differences explained a substantial 46% of objective performance and 19% of subjective performance in a mixed-motive bargaining exercise. Previous work may have understated the influence of individual differences because conventional research designs require specific traits to be identified and measured. Exploratory analyses of a battery of traits revealed few reliable associations with consistent individual differences in objective performance-except for positive beliefs about negotiation, positive affect, and concern for one's outcome, each of which predicted better performance. Findings suggest that the field has large untapped potential to explain substantial individual differences. Limitations, areas for future research, and practical implications are discussed.     

Rejecting Sectarianism: Palestinian Christians' Role in Muslim–Christian Relations

The study of Muslim–Christian relations often focuses on Islamic theology and Muslim behavior while overlooking the role that Christians play in shaping interreligious encounters. This article examines a series of historical examples from various periods of Palestinian history that highlight Arab Christians' insistence that they were Palestinian Arabs first and were fully engaged in the nationalist movement. Palestinian Christians' approach to local politics, even in the face of interreligious conflict, allowed them to maintain far better relations with Muslims than Arab Christians in some neighboring Arab countries. By way of comparison, the article highlights the Druze's acceptance of a unique communal relationship to the Zionist leadership and later, to the state of Israel. The article concludes that, while modern Islamism presents a challenge to minority Christian groups, historical examples suggest that Christians' actions have a profound impact on the nature of Christian–Muslim relations.
