What is the nature of this machinery? Much of linguistics is preoccupied with syntax. Logical structure alone, however, is insuffi cient for understanding meaning. For instance, a father tells his 7-year-old daughter, “If you clean your room, we’ll go to the movies.” If the girl reduced his message to the logical form “if P, then Q,” and reasoned logically, she would conclude that the statement does not imply “if not P, then not Q,” because this would be committing a logical fallacy called “denial of the antecedent.” Avoiding this logical fallacy, she would reason that her father is not implying that if she does not clean up her room, they will not go to the movies. Yet child and father both know in a blink that this is exactly what is meant. A logical approach to meaning fails both descriptively and normatively: It does not describe how s...

My research embraces both views by exploring the idea that emotions are “designed” as cognitive systems for generating “affective information” (Schwarz & Clore, 1983; Ketelaar & Clore, 1997). Rather than simply demonstrating that emotions can influence decision-making in very peculiar ways (something we already know), my research focuses instead on the question of whether emotions are “designed” to provide affective information that serves to aid, rather than impair, personal and social decision-making (Ketelaar & Au, 2003; Ketelaar & Clore, 1997; Ketelaar & Todd, 2001).

Participants (N ϭ 196) played a computerized prisoner's dilemma game with a virtual opponent who defected in the second round of the game. After the defection, a photograph of the opponent was shown, displaying a blushing or a nonblushing face. In a subsequent Trust Task, the blushing opponent was entrusted with more money than the nonblushing opponent. In further support of the alleged remedial properties of the blush, participants also indicated that they trusted the blushing opponent more, expected a lower probability that she would defect again, and judged the blushing opponent more positively.

Some studies have shown that people are happier when earning money in constant payments, and spending money on significant others. However, some findings suggest that people with financial expertise may have different preferences based on the time value of money. The current study was designed to address this issue by asking both financial novices and financial experts if earning money at decreasing, constant or increasing rates would make them happier. By replicating and, more

In contrast, the authors propose that the degree of negative affect that these behaviors induce in observers is largely responsible for their attributional weight. Studies 1 and 2 demonstrate an association between the amount of negative affect induced by immoral behaviors and their attributional weight. Studies 3 and 4 provide causal evidence for this idea by either “adding in” or “taking away” the negative affect associated with immoral behaviors to influence their attributional weight. Finally, Study 5 demonstrates that negative affect can be induced through a variety of negative emotions (disgust, sadness, and fear), with similar results. It is argued that it is difficult to account for these data solely on the basis of traditional cognitive variables, and so a theory that includes an emphasis on affect as a causal variable is desirable.

First, Lloyd and Feldman claim that our description of the core metatheoretical assumptions of modern evolutionary theory overemphasizes the role of inclusive fitness (i.e., the so-called selfish gene approach) at the expense of underemphasizing important alternative approaches (e.g., multilevel selection models, gene-culture coevolution models). Second, Lloyd and Feldman criticize some of the methods and assumptions that ostensibly characterize the evolutionary psychology research program. These criticisms concern the conceptualization of organisms as inclusive fitness maximizers, the soundness of the epistemology of evolutionary psychology, the modularity of psychological mechanisms, and the universality of psychological mechanisms. In the first part of this rejoinder, we acknowledge that different schools of thought exist regarding the plausibility and importance of various metatheoretical assumptions in human evolutionary psychology. We argue that to date, however, only the gene-centered adaptationist program (consistent with inclusive fitness theory) has demonstrated scientific progressivity by generating a coherent, integrated body of new knowledge and explaining away several apparent anomalies. In the second part of this rejoinder, we discuss several misunderstandings that underlie Lloyd and Feldman's criticisms of human evolutionary psychology. The Role of Inclusive Fitness Theory in Evolutionary Psychology Lloyd and Feldman (this issue) criticize our reference to inclusive fitness theory as providing the foundation of modern evolutionary theory:
