When Sharing Is Not Caring: Does (un)Certainty About Bill Payment Method Lead Diners to Consume More and Spend More Money?

Previous work has demonstrated that unacquainted participants in an experimental, restaurant‐like setting consume more when they know in advance that the bill will be split evenly rather than paid according to individual consumption. Real life, however, often differs from these experimental settings in two important ways. First, unlike random groups of participants, diners who eat together are frequently friends or colleagues. Second, payment method (even vs. individual payment) is usually unknown (i.e. uncertain) at the time people place their orders, and is determined when the check arrives. The current research tests the ecological validity of the association between consumption amount and payment method. Study 1 was conducted in a natural setting with organic groups of diners. Some were asked to state their desired payment method before ordering (Certain condition); others did so only after asking for the check (Uncertain condition). In both conditions, even payment (as opposed to individual payment) was associated with greater consumption amount. However, overall, consumption amount was lower among diners in the Uncertain condition than among those in the Certain condition. Study 2 presents a controlled follow‐up experiment showing that eliminating diners' prior expectations regarding the payment method—by informing them that the payment method will be randomly determined after the consumption decision—eliminates the relationship between payment method and consumption amount. This study further indicates that when diners are uncertain what the payment method will be, even bill‐splitting has negative implications for their subsequent social interactions, expressed in retribution tendencies.

Positive behavioral contrast across food and alcohol reinforcers.

The present study examined behavioral contrast during concurrent and multiple schedules that provided food and alcohol reinforcers. Concurrent-schedule contrast occurred in the responding reinforced by food when alcohol reinforcers were removed. It also occurred in the responding reinforced by alcohol when food was removed. Multiple-schedule contrast appeared for food when alcohol reinforcers were removed, but not for alcohol when food was removed. These results show that behavioral contrast may, but does not always, occur across qualitatively different reinforcers. They also show that multiple-schedule contrast may be more difficult to produce than concurrent-schedule contrast. The results have implications for a model of alcohol consumption.

The temporal organization of behavior on periodic food schedules.

Various theories of temporal control and schedule induction imply that periodic schedules temporally modulate an organism's motivational states within interreinforcement intervals. This speculation has been fueled by frequently observed multimodal activity distributions created by averaging across interreinforcement intervals. We tested this hypothesis by manipulating the cost associated with schedule-induced activities and the availability of other activities to determine the degree to which (a) the temporal distributions of activities within the interreinforcement interval are fixed or can be temporally displaced, (b) rats can reallocate activities across different interreinforcement intervals, and (c) noninduced activities can substitute for schedule-induced activities. Obtained multimodal activity distributions created by averaging across interreinforcement intervals were not representative of the transitions occurring within individual intervals, so the averaged multimodal distributions should not be assumed to represent changes in the subject's motivational states within the interval. Rather, the multimodal distributions often result from averaging across interreinforcement intervals in which only a single activity occurs. A direct influence of the periodic schedule on the motivational states implies that drinking and running should occur at different periods within the interval, but in three experiments the starting times of drinking and running within interreinforcement intervals were equal. Thus, the sequential pattern of drinking and running on periodic schedules does not result from temporal modulation of motivational states within interreinforcement intervals.     

Deci and Ryan's cognitive evaluation theory of intrinsic motivation: A set of common sense theorems

Cognitive evaluation theory as put forward by Deci and Ryan (1985) is examined. The theory, which deals with intrinsic and extrinsic motivation, has inspired considerable amount of empirical research in the last two decades. However, contrary to the mainstream view and that of its authors, it is argued here that the theory consists of necessary truths of common sense (folk) psychology, rather than contingent and empirically testable hypotheses. As such the theory spells out what must necessarily be the case in human motivation and the empirical evidence amassed to test its validity is irrelevant. Such testing should be abandoned if its purpose is to appraise the truth value of the theory's propositions. To empirically test necessary true propositions is not only redundant in such cases, but also a waste of time and resources.     

COGNITIVE THEISM: SOURCES OF ACCOMMODATION BETWEEN SECULARISM AND RELIGION

Abstract. Religion persists, even within enlightened secular society, because it has adaptive functions. In particular, Ralph Wendell Burhoe's theory holds that religion is the repository of cultural wisdom that most encourages mutual altruism among nonkin, long-term social survival, and human progress. This article suggests a variant of Burhoe's rationalized naturalistic view. Cognitive theism is a proposal that secularists sometimes take religion on its own terms by suspending disbelief about God. If we consider particular human capacities and limitations in memory, perception, personality, and motivation, the regulated “mind expansion” of cognitive theism may help us to evaluate, coordinate, and invigorate things in a modern environment. In this environment, communicative and travel technologies have led to a high loading of consciousness with a historically unusual diverse range of experiences and responsibilities, a high rate of cultural change relative to biological evolution, and a tendency to factionalize. Burhoe's extension of the concept of symbiosis to the coevolution of culture and genes is modified here in recognition of individual differences and of individuals' potential for choosing strategies, recombining in groups, and learning. In human biocultural symbiont pools, cultural phenomena can evolve while changing partners in a dance with genetic substrates, a dance that broadly supports these substrates. In the context of diversity and incessant change in a large predominantly secular community, Judeo-Christian monotheism can have a valuable advisory unifying function.
