Experimental psychologists in the learning tradition stress the importance of three of the authors' four key variables of experimental design. We review research investigating the roles played by these variables in studies of choice from our laboratory. Supporting the authors' claims, these studies show that the effects of these variables are not fixed and should not be taken for granted.

Mood and optimism have been demonstrated to influence risk-taking decisions; however, the literature on mood, optimism, and decision-making is mixed and conducted primarily with western samples. This study sought to address this gap in the literature by examining the impact of mood and dispositional optimism on risk-taking and whether these associations differed between undergraduate students from the United States and the People’s Republic of China. Both samples completed a dispositional optimism questionnaire and an autobiographical mood induction task. They were then (...) tasked with choosing to complete the Raven’s Advanced Progressive Matrices reasoning task on easy, medium, or hard difficulty for hypothetical money. Selecting harder difficulties was interpreted as more risk-taking due to a higher chance of failure. More positive mood and higher dispositional optimism were associated with decreased risk-taking, i.e., selecting easier puzzle difficulties, in the American sample but increased risk-taking decisions, i.e., selecting harder difficulties, in the Chinese sample. These findings suggest that the effect of mood and optimism on decision-making may differ by nationality and/or culture. (shrink)

Subjects have a rich history of decision making which would be expected to affect reasoning in new tasks. For example, averaging, a strategy that is effectively used in many decisions, may help explain the conjunction fallacy. Before resorting to accounts based on phylogeny, more parsimonious accounts in terms of ontogeny should be explored.

There are good reasons why social psychologists have emphasized the negative side of human reasoning. They are simply following humans' tendency to pay particular attention to unusual occurrences. Attempts to refocus attention onto a wider range of behavior should include the influence of learning on both normative and non-normative behavior.

This theory accords to volitions the status of basic mental actions, maintaining that these are spontaneous exercises of the will--a "two-way" power which ...

If Tool Theory is buttressed by fundamental concepts of conditioned reinforcement and extinction, a dependence on Drug Theory may not be necessary. (Published Online April 5 2006).

The author presents and defends three theses: (1) "the first is that it is not profitable for us at present to do moral philosophy; that should be laid aside at any rate until we have an adequate philosophy of psychology." (2) "the second is that the concepts of obligation, And duty... And of what is morally right and wrong, And of the moral sense of 'ought', Ought to be jettisoned if this is psychologically possible...." (3) "the third thesis is that (...) the differences between the well-Known english writers on moral philosophy from sidgwick to the present day are of little importance." (staff). (shrink)

We agree with Rachlin's argument that altruism is best understood as a case of self-control, and that a behavioral analysis is appropriate. However, the appeal to teleological behaviorism and the value of behavioral patterns may be unnecessary. Instead, we argue that altruism can generally be explained with traditional behavioral principles such as negative reinforcement, conditioned reinforcement, and rule-governed behavior.

The field of Philosophy of Sport has been developing in Anglo-Saxon scholarship since the 1960s and since then has achieved considerable consolidation. However, this is a progressing field in Latin American countries like Brazil. This paper aims to analyse the trajectory of the Philosophy of Sport in Brazil, presenting an overview of its development since the 1980s and some prospects that have been generated since the turn of the century. In conclusion, the article points out that the field of Philosophy (...) of Sport in Brazil is in the process of disciplinary consolidation, presenting a plurality of agents, institutions and theoretical approaches in its structure.

Derek Parfit’s view of personal identity raises questions about whether advance decisions refusing life-saving treatment should be honored in cases where a patient loses psychological continuity; it implies that these advance decisions would not be self-determining at all. However, rather than accepting that an unknown metaphysical ‘further fact’ underpins agential unity, one can accept Parfit’s view but offer a different account of what it implies morally. Part II of this article argues that contractual obligations provide a moral basis for honoring (...) advance decisions refusing life-saving and/or life-sustaining medical treatment; advance decisions have similarities to contracts, such as life insurance policies and will-contracts, that come into effect when the psychological discontinuity is through death.

Heraklits Denken und seine philosophischen Positionen haben einen ungeheuren Einfluss im Altertum, in der Neuzeit und bis in die Moderne hinein ausgeübt. Die Beiträge dieses Bandes machen die kulturellen Bedingungen sichtbar, unter denen dieses Denken entstanden ist, und helfen, sowohl den,Dunklen' selbst, wie er seit der Antike genannt wurde, als auch seine Wirkung systematisch besser zu verstehen. Alle Beiträge gehen auf eine internationale Konferenz zurück, die im Oktober 2013 ausgewiesene Spezialisten zu einem umfassenden Dialog in Ephesos zusammenführte. Im Zusammenwirken verschiedener (...) Disziplinen ließ sich Heraklits Ort in der Philosophie- und Geistesgeschichte genauer bestimmen, als das in den bisher vorwiegend auf philosophiehistorisch-philologische Aspekte fokussierten Darstellungen geschehen ist. Das Alleinstellungsmerkmal der Konferenz in ihrer Orientierung am genius loci und auch die damit einhergehende Einbeziehung historischer und archäologischer Fragestellungen bedeutet etwas Neues für die Heraklit-Forschung: Das Aufzeigen der Verbindungen zwischen der naturräumlichen Situation in Ephesos zur Zeit Heraklits, dem Verhältnis des Denkers zu seiner Stadt sowie der Rolle seiner Reflexion auf die Bedingungen menschlicher Erkenntnis und ihrer Vermittlung.

It is a commonly accepted view that men think to live, and do not live to think, that conation, and not cognition, is the primary object of living. Impression, affect, and expression constitute the complete psychic process. The term philosophy, the love of wisdom, also suggests that man's thought has a practical and not a theoretical objective. In this connection, however, two errors must be avoided: on the one hand an exaltation of the intellect as in rationalism, and on the (...) other hand a depreciation of the intellect as in pragmatism.

The poet’s words: “A man’s reach should exceed his grasp” are not merely a command of whatought to be, they are a description of what is. Man has always been stretching himself beyond his own measure. He has a sense of the Infinite: Eternity has been set in his heart: he has not been content to look only on the things seen, his gaze has ever been towards the Unseen. Whatever stage of development he may have reached, he seeks for, (...) and strives after, what is above and beyond himself and his world. In science he tries to get behind thephenomenalreality as his senses apprehend it, to thenoumenal, mind. In philosophy he endeavours to bring the multiplicity of his experience, outer and inner, into a unity that will evidence itself to his reason as coherent, and not contradictory. In morality he is not content with the customs and standards of the society of which he is a member; but conscious of their inadequacy, he conceives and aspires to realize an ideal adequate to his nature; hisought to beis always challenging hisis. The impulse or motive of progress in all spheres of human interest and activity is “the best is yet to be.”. (shrink)

Game-theoretic rationality is not generally observed in human behavior. One important reason is that subjects do not perceive the tasks in the same way as the experimenters do. Moreover, the rich history of cooperation that participants bring into the laboratory affects the decisions they make.

We present evidence supporting the target article's assertion that while the presentation of base-rate information in a natural frequency format can be helpful in enhancing sensitivity to base rates, method of presentation is not a panacea. Indeed, we review studies demonstrating that when subjects directly experience base rates as natural frequencies in a trial-by-trial setting, they evince large base-rate neglect.

We applaud Domjan et al. for providing an elegant account of Pavlovian feed-forward mechanisms in social behavior that eschews the pitfall of purposivism. However, they seem to imply that they have provided a complete account without provision for operant conditioning. We argue that operant conditioning plays a central role in social behavior, giving examples from fish and infant behavior.

Grandparental altruism may be partially understood in the same way as other instances of altruism. Acts of altruism often occur in a context in which the actor has a broader sense of cause and effect than is evident in more typical behavioral interactions where cause and effect appear relatively transparent. Many believe that good deeds will ultimately produce good results.

Pour exprimer la foi chrétienne, certains théologiens n’hésitent pas à reprendre des notions scientifiques comme éléments du discours théologique. L’article s’interroge sur l’apport et l’opportunité de cette pratique à partir d’un exemple, la notion de complémentarité au sens où N. Bohr l’a définie en physique. In order to get a theological discourse adapted to the cultural environment, several theologians take up scientific notions. In this paper are examined the interest and the impact of this way of doing theology considering an (...) example, the complementarity as defined by N. Bohr. (shrink)

Future economic game research should include: (1) within-culture comparisons between individuals exposed and not exposed to market integration; (2) use of a game (such as the “Sharing Game”) that enables subjects to maximize their earnings while also maximizing those of the other participant; and (3) assessment of performance in a repeated-trials format that might encourage sensitivity to the games' economic contingencies.

The target authors make a strong case for parallels between human and nonhuman metacognition. The case may be bolstered by an appeal to the literatures on commitment and self-control and to that on observing behavior.
