ScriptingRT is a new open source tool to collect response latencies in online studies of human cognition. ScriptingRT studies run as Flash applets in enabled browsers. ScriptingRT provides the building blocks of response latency studies, which are then combined with generic Apache Flex programming. Six studies evaluate the performance of ScriptingRT empirically. Studies 1–3 use specialized hardware to measure variance of response time measurement and stimulus presentation timing. Studies 4–6 implement a Stroop paradigm and run it both online and in the laboratory, comparing ScriptingRT to other response latency software. Altogether, the studies show that Flash programs developed in ScriptingRT show a small lag and an increased variance in response latencies. However, this did not significantly influence measured effects: The Stroop effect was reliably replicated in all studies, and the found effects did not depend on the software used. We conclude that ScriptingRT can be used to test response latency effects online.

Sociosexuality refers to individual differences in interest and willingness to engage in sexual activity without an emotional connection. Unrestricted sociosexuality is associated with a greater likelihood of infidelity and with poorer relationship quality. However, previous research has failed to examine relationship-specific characteristics that may moderate these findings. Two studies of romantically involved adults examined whether relationship commitment and different relationship agreement types moderate the associations between unrestricted sociosexuality and infidelity. Study 1 (N = 300) showed that individuals in consensual monogamous (CM) relationships with extradyadic sex (EDS) experiences were more sociosexually unrestricted than individuals without such experiences. The positive association between unrestricted sociosexuality and EDS emerged only for less, but not more, committed individuals. Study 2 (N = 270) replicated these results. Furthermore, results showed that individuals in consensual nonmonogamous relationships (CNM) relationships were the most sociosexually unrestricted, but no differences emerged in relationship commitment or satisfaction, when compared to individuals in CM relationships without prior EDS. Individuals in CM relationship with prior EDS were the least committed and satisfied. The negative association between unrestricted sociosexuality and both relationship quality indicators emerged for all individuals in CM relationships, but it was nonsignificant for individuals in CNM relationships. Implications are discussed.

Introduction: Several theoretical models and intervention programs overlook the importance of individual motivations for the decision to have condomless sex. For instance, people focused on promotion (i.e., eager to pursue pleasure) report less intentions to use condoms, because they perceive a lower risk of acquiring sexually transmitted infections (STIs). Aim: We aimed at understanding to what extent individual motivations are predictive of condomless sex behavior among single individuals. Methods: A sample of 415 Portuguese individuals (254 women) with ages ranging from 18 to 46 years (M = 23.30, SD = 5.28) were recruited to a cross-sectional study. All participants were neither dating nor in a romantic relationship at the time of the study. The link to an anonymous web survey was shared in social networking platforms. Main Outcome Measures: The survey included self-reported demographic variables (e.g., age, gender), recent condomless sex behavior, and previously validated measures assessing regulatory focus in sexuality, ability in sexual restraint, perceived control over condom use, perceived security with sex partners, and salience of the condom use norm. Results: More than two-thirds of the sample had recently engaged in condomless sex. A logistic regression showed that condomless sex was more likely for participants predominantly focused on promotion in sexuality. It was also more likely among less educated participants, those with a lower ability to restrain their sexual behavior, those who perceive to have less control over condom use, those for whom the condom use norm was less salient, and those who perceived to be safer with their sex partners. No other results were significant. Clinical Implications: Our results can be informative to sexual health care professionals when planning strategies to increase condom use awareness, by specifically considering the role of specific individual motivations. PREDICTORS OF CONDOMLESS SEX 2 Strengths & Limitations: This is the first study showing that individual motivations uniquely contribute to the decision to have condomless sex. This study has two main limitations that constraint the generalizability of the findings: (a) cross-sectional data prevents us from establishing causality, and (b) individual data does not account for dyadic processes in sexuality (e.g., condom use negotiation). Conclusion: Our findings showed that condomless sex results from an individual focus on seeking pleasure, a lack of control in sexual behavior, and a perception of sex partners as more trustworthy. Overall, these findings are likely to help researchers and health care professionals improving theoretical models predicting condom use and preventing the spread of STIs.
