Three studies examined the impact of a treatment designed to instill resistance to deceptive persuasive messages. Study 1 demonstrated that after the resistance treatment, ads using illegitimate authority-based appeals became less persuasive, and ads using legitimate appeals became more persuasive. In Study 2, this resistance generalized to novel exemplars,(More)
In a recent article, Harris (2003) concluded that the data do not support the existence of evolved sex differences in jealousy. Harris' review correctly identifies fatal flaws in three lines of evidence (spousal abuse, homicide, morbid jealousy), but her criticism of two other lines of evidence (self-report responses, psychophysiological measures) is based,(More)
The theory of evolved sex differences in jealousy predicts sex differences in responses to sexual infidelities and emotional infidelities. Critics have argued that such differences are absent in studies that use continuous measures to assess responses to hypothetical infidelities or in studies that assess responses to real infidelities. These criticisms(More)
Examinations of post-choice decision-making behavior often involve two successive choices. At time 1, participants choose between two equally attractive items. At time 2, participants choose between the unchosen item from time 1 and a new item that is roughly equal in attractiveness to the other two. The option rejected at time 1 will tend to again be(More)
Chen argued that the proper null hypothesis for free-choice studies examining shifts in choice was 66.7%. Sagarin and Skowronki (2009) questioned the appropriateness of this value, noting that it was based on an unwarranted assumption that subjects always choose preferred options over less preferred options. In this paper, we respond to the points raised by(More)
Studies have long investigated similarities and differences in men’s and women’s mate preferences. This study sought to expand on previous research by investigating whether mate value moderated participants’ design of mates. Using both a budgeted and a non-budgeted mate design task, we investigated the effect of mate value on the design of a mate. We found(More)
When data analyses produce encouraging but nonsignificant results, researchers often respond by collecting more data. This may transform a disappointing dataset into a publishable study, but it does so at the cost of increasing the Type I error rate. How big of a problem is this, and what can we do about it? To answer the first question, we estimate the(More)
Many individuals intend to exercise, but fail to link this intention to behavior. The present study examined the impact of an implementation intention intervention (i.e., instructions to form specific if-then plans) on an exercise intention-behavior relationship among working adults who varied in reported occupational stress levels. Results indicated that(More)
Past demonstrations of sex differences in jealousy have generally employed Buss et al.’s [Psychol. Sci. 3 (1992) 251] forced-choice methodology, a limitation criticized by DeSteno and Salovey [Psychol. Sci. 7 (1996) 367]. The present studies address this criticism by demonstrating the sex difference using both forced-choice and continuous measures of(More)
