The Impact of Conflict Issues on Fixed-Pie Perceptions, Problem Solving, and Integrative Outcomes in Negotiation

It is argued that a negotiator's fixed-pie perception, cooperative motivation, problem-solving behavior, and integrative outcomes are influenced by the content of the negotiation—the conflict issue. Negotiation involves conflicting interests, conflicting ideas about intellective problems, or conflicting ideas about evaluative problems. Study 1 showed that individuals in a negotiation about interests have a stronger fixed-pie perception and have a lower cooperative motivation than individuals in an evaluative negotiation, with intellective negotiations taking an intermediate position. Study 2 showed that individuals in a negotiation about interests made more trade-offs and reached higher joint outcomes than individuals in an intellective or evaluative negotiation. Study 3 replicated this finding in a field study. The studies bridge insights from negotiation research and decision-making research and show that the conflict issue has important effects on the negotiation process.

I respond to an argument made by Gunnar Björnsson and Ragnar Francén Olinder against motivational internalism. Björnsson and Olinder present a hypothesis in which all of us are selfishly motivated to act in accordance with our moral judgments. The conceivability of such a possibility, they argue, rules out motivational internalism. I argue that this is not the case, and that, according to one dominant view about moral judgments, the agents in the hypothesis do not make genuine moral judgments. One therefore cannot argue decisively against motivational internalism without arguing against this view about moral judgments.     

Re-acquaintance with qualia

Frank Jackson argued, in an astronomically frequently cited paper on ‘Epiphenomenal qualia’[Jackson 1982 Jackson, F. C. 1982. Epiphenomenal Qualia. Philosophical Quarterly, 32: 127–136. [Crossref], [Web of Science ®] , [Google Scholar] that materialism must be mistaken. His argument is called the knowledge argument. Over the years since he published that paper, he gradually came to the conviction that the conclusion of the knowledge argument must be mistaken. Yet he long remained totally unconvinced by any of the very numerous published attempts to explain where his knowledge argument had gone astray.

Eventually, Jackson did publish a diagnosis of the reasons why, he now thinks, his knowledge argument against materialism fails to prove the falsity of materialism [Jackson 2005 Jackson, F. C. 2005. Foreword to There's Something About Mary: Frank Jackson's Knowledge Argument, Edited by: Ludlow, P., Nagasawa, Y. and Stoljar, D. Cambridge, MA: MIT Press.  [Google Scholar]. He argues that you can block the knowledge argument against materialism—but only if you tie yourself to a dubious doctrine called representationalism.

We argue that the knowledge argument fails as a refutation of either representational or nonrepresentational materialism. It does, however, furnish both materialists and dualists with a successful argument for the existence of distinctively first-person modes of acquaintance with mental states. Jackson's argument does not refute materialism: but it does bring to the surface significant features of thought and experience, which many dualists have sensed, and most materialists have missed.     

Relations Among Preschool Children's Understanding of Visual Perspective Taking,False Belief,and Lying

This study investigated the relations among preschool children's ability to understand that other people see things differently than they do, that other people can believe things differently than the children know to be true, and that they can manipulate others' beliefs through intentional lying. Children between the ages of 3 and 5 were given tasks that tested their knowledge of Level 2 visual perspective taking, understanding of false belief, and the discriminative use of deceptive ploys. The Peabody Picture Vocabulary Test (PPVT-III) was administered as a measure of language proficiency. The children's scores on the three types of tasks were correlated with each other and with children's age, but not with scores on the PPVT-III. Most children either passed all the tasks or failed all the tasks. Regression analyses indicated that scores on visual perspective taking and false belief independently predicted each other, and scores on false belief and the discriminative use of deception independently predicted each other. The results provide evidence that advances in visual perspective taking, false belief understanding, and the discriminative use of deceptive ploys are developmentally related and occur in close synchrony.     

The role of joint attention in the development of infants' play with objects

Year-old infants' play was scored within and outside joint attention with mother and when alone for four levels of maturity: stereotypical, inappropriate relational, appropriate relational, functional. Maternal sensitivity within joint attention was rated on two measures: following infants' interests and scaffolding infants' activities. Infants' play was more advanced with mother than when alone. With mother, infants had more functional and appropriate relational play within joint attention and more stereotypical play outside joint attention, indicating more advanced play within joint attention and more immature play outside joint attention. Functional play within joint attention, but not outside joint attention, correlated with functional play when alone. Mothers' ability to scaffold infants' activities within joint attention may be particularly facilitative to infants' advanced play.     

Reinforcing effects of caffeine in coffee and capsules.

In a residential research ward the reinforcing and subjective effects of caffeine were studied under double-blind conditions in volunteer subjects with histories of heavy coffee drinking. In Experiment 1, 6 subjects had 13 opportunities each day to self-administer either a caffeine (100 mg) or a placebo capsule for periods of 14 to 61 days. All subjects developed a clear preference for caffeine, with intake of caffeine becoming relatively stable after preference had been attained. Preference for caffeine was demonstrated whether or not preference testing was preceded by a period of 10 to 37 days of caffeine abstinence, suggesting that a recent history of heavy caffeine intake (tolerance/dependence) was not a necessary condition for caffeine to function as a reinforcer. In Experiment 2, 6 subjects had 10 opportunities each day to self-administer a cup of coffee or (on different days) a capsule, dependent upon completing a work requirement that progressively increased and then decreased over days. Each day, one of four conditions was studied: caffeinated coffee (100 mg/cup), decaffeinated coffee, caffeine capsules (100 mg/capsule), or placebo capsules. Caffeinated coffee maintained the most self-administration, significantly higher than decaffeinated coffee and placebo capsules but not different from caffeine capsules. Both decaffeinated coffee and caffeine capsules were significantly higher than placebo capsules but not different from each other. In both experiments, subject ratings of "linking" of coffee or capsules covaried with the self-administration measures. These experiments provide the clearest demonstrations to date of the reinforcing effects of caffeine in capsules and in coffee.     

Smoking following myocardial infarction: a critical review of the literature

This paper critically reviews the available research on the effects of smoking cessation following acute myocardial infarction (MI). Studies that have examined the rate of smoking cessation following an MI indicate that approximately 1/3 to 1/2 of the smokers who suffer from MI subsequently reduce or quit smoking. Furthermore, studies that have examined subsequent mortality and morbidity suggest that individuals who quit smoking following MI exhibit lower mortality and morbidity than those who continue to smoke. It is argued that past studies may have overestimated post-MI smoking cessation rates, and by failing to control for a priori differences between quitters and continuing smokers (e.g., MI severity) may have underestimated the negative effects of smoking following MI. Suggestions for future research are proposed.     

A behavioural-pharmacological treatment of dually addicted patients

maintenance appears to be an effective means of treating narcotic addiction both because it blocks the effects of heroin and because patients are willing to accept methadone treatment. However, alcoholism has been found commonly to complicate methadone maintenance and to result in treatment failure. The regular ingestion of disulfiram, a drug which blocks ethanol metabolism, could provide a solution to this problem, but alcoholics tend not to persist in taking this drug, because unlike methadone it possesses no reinforcing properties. This paper describes a novel technique whereby the reinforcing action of methadone has been employed to maintain disulfiram-taking, and thus to arrest alcohol abuse and consequent treatment failure.
