In four experiments, we examined the effects of exposure to unfamiliar tone sequences on melodic expectancy and memory. In Experiment 1, 30 unfamiliar tone sequences (target sequences) were presented to listeners three times each in random order (exposure phase), and listeners recorded the number of notes in each sequence. Listeners were then presented target and novel sequences and rated how well the final note continued the pattern of notes that preceded it. Novel sequences were identical to target sequences, except for the final note. Ratings were significantly higher for target sequences than for novel sequences, illustrating the influence of exposure on melodic expectancy. Experiment 2 confirmed that without exposure to target sequences, ratings were equivalent for target and novel sequences. In Experiment 3, new listeners were assessed for explicit memory for target sequences following the exposure phase. Recognition of target sequences was above chance, but unrelated to expectancy judgments in Experiment 1. Experiment 4 replicated the exposure effect, using a modified experiment design, and confirmed that the effect is not dependent on explicit memory for sequences. We discuss the idea that melodic expectancies are influenced by implicit memory for recently heard melodic patterns. 相似文献

This study examines (1) how previous history with infidelity influences perceptions of cheating behaviors, and (2) sex's impact on ratings of cheating behaviors. A total of 83 undergraduate students enrolled in psychology courses volunteered to participate through an anonymous online survey. Participants rated sexual and emotional behaviors on a scale that ranged from “always” to “never,” indicating if the behavior was perceived as cheating. Individuals that had previous experience with infidelity either as the involved or non-involved partner rated sexual behaviors higher than those with no experience with infidelity, while non-involved partners rated emotional behaviors higher than the rest. Overall, females rated sexual and emotional behaviors higher than males. Non-involved males rated sexual behaviors higher than non-involved female partners. However, males who have not committed an infidelity rated sexual behaviors lower than any other group. The results provide further evidence that perceptions of cheating behaviors are influenced by gender and one's own history of infidelity, including both involved and non-involved roles. 相似文献

We developed a new test to examine incidental temporal order memory for a self-generated sequence of tasks one might complete in everyday life. Young and older adults were given 10 cards, each listing a task one might accomplish in a typical day. Participants were asked to self-generate a “to do” list by placing the 10 cards in a sequence representing the order in which they would accomplish the tasks, but were not informed of a subsequent memory test. We assessed immediate free recall, delayed free recall, and delayed cued recall for the order of the tasks in the sequence. Older adults were significantly impaired relative to young adults on immediate free recall, delayed free recall, and delayed cued recall. Correlation analyses with standardized neuropsychological tests provide preliminary evidence for construct validity for our test, which is portable and can be rapidly administered in clinical or laboratory settings. 相似文献

The human sentence processor is able to make rapid predictions about upcoming linguistic input. For example, upon hearing the verb eat, anticipatory eye‐movements are launched toward edible objects in a visual scene (Altmann & Kamide, 1999). However, the cognitive mechanisms that underlie anticipation remain to be elucidated in ecologically valid contexts. Previous research has, in fact, mainly used clip‐art scenes and object arrays, raising the possibility that anticipatory eye‐movements are limited to displays containing a small number of objects in a visually impoverished context. In Experiment 1, we confirm that anticipation effects occur in real‐world scenes and investigate the mechanisms that underlie such anticipation. In particular, we demonstrate that real‐world scenes provide contextual information that anticipation can draw on: When the target object is not present in the scene, participants infer and fixate regions that are contextually appropriate (e.g., a table upon hearing eat). Experiment 2 investigates whether such contextual inference requires the co‐presence of the scene, or whether memory representations can be utilized instead. The same real‐world scenes as in Experiment 1 are presented to participants, but the scene disappears before the sentence is heard. We find that anticipation occurs even when the screen is blank, including when contextual inference is required. We conclude that anticipatory language processing is able to draw upon global scene representations (such as scene type) to make contextual inferences. These findings are compatible with theories assuming contextual guidance, but posit a challenge for theories assuming object‐based visual indices. 相似文献

Actor‐Partner Interdependence Models (APIM) and Voting Behavior: Methodology and Applications 下载免费PDF全文
Recently, the social sciences have witnessed a rising interest in dyadic design, as an efficient way to disentangle mechanisms of interpersonal influence. Despite the relevance of this design to political research, few efforts have been made to collect and efficiently analyze dyadic data. In this article, we suggest the Actor‐Partner Interdependence Model as a useful tool to test bidirectional effects in dyadic data on political attitudes and behaviors. The model explicitly assumes that members of a dyad (reciprocally identified as actor and partner) involved in political communication are interdependent and influence each other. We apply the model to estimate the effect of partner's party identification on actor's vote choice, using 1996 Indianapolis–St. Louis dyadic data. Results show that partner's party identification is significantly associated with vote choice. Moreover, we show that influence between dyad members is moderated by their intimacy and that an increased difference in socioeconomic status between dyad members tips the balance of the effect in favor of the individual with more resources. Our conclusions point to the effectiveness of APIM in modeling interdependent asymmetric relations and call for increasing efforts in collecting dyadic data and in developing proper tools for their analysis. 相似文献

President Clinton's charge to the Advisory Committee on Human Radiation Experiments included the identification of ethical and legal standards for evaluating government-sponsored radiation experiments conducted during the Cold War. In this paper, we review the traditional account of the history of American research ethics, and then highlight and explain the significance of a number of the Committee's historical findings as they relate to this account. These findings include both the national defense establishment's struggles with legal and insurance issues concerning human experiments, and the medical profession's perspective on human experimentation in the years following the Nuremberg Medical Trials. We conclude that the Committee's work both enriches the traditional view of the history of research ethics and opens important new areas for study. 相似文献

Research has shown that more acculturated Latino adolescents are at increased risk for delinquent behavior relative to their less acculturated counterparts. The present study examined the mediating effects of seven variables hypothesized to account for the empirical link between acculturation status and delinquent activity for a sample of Mexican American adolescents. Mediational analyses provided support for four of the putative mediators which included family conflict, maternal monitoring, inconsistent discipline, and negative peer hassles. Examined together, these variables totally mediated the effect of acculturation status on delinquent behavior. In addition, family conflict and maternal monitoring uniquely accounted for a significant proportion of the mediated variance above that explained by the other variables in the model. Adolescent's cultural identity, perceived discrimination, and maternal acceptance were not supported as mediators. 相似文献

It has been long known that people blame victims for the bad things that happen to them, and that people blame victims more when the victims experience severe difficulties than when they experience minor difficulties, even if the victims were not particularly irresponsible. Little previous research has examined victim blaming in middle-age and older adults. One hundred and forty-five adults in 3 age groups (18–34, 35–59, and 60–84) read 4 scenarios (2 accidents, 1 crime, and 1 fire) imbedded in other scenarios. The scenarios were varied so that the victim is either very irresponsible or not very irresponsible, and the outcome is mild or severe. The oldest group of participants blamed the victims more than the other groups. However, in contrast to the typical severity effect, the oldest group blamed the very irresponsible victim more when the outcome was mild than they did when the outcome was severe. 相似文献
