When study is spaced across sessions (versus massed within a single session), final performance is greater after spacing. This spacing effect may have multiple causes, and according to the mediator hypothesis, part of the effect can be explained by the use of mediator-based strategies. This hypothesis proposes that when study is spaced across sessions, rather than massed within a session, more mediators will be generated that are longer lasting and hence more mediators will be available to support criterion recall. In two experiments, participants were randomly assigned to study paired associates using either a spaced or massed schedule. They reported strategy use for each item during study trials and during the final test. Consistent with the mediator hypothesis, participants who had spaced (as compared to massed) practice reported using more mediators on the final test. This use of effective mediators also statistically accounted for some – but not all of – the spacing effect on final performance. 相似文献

How Cross‐Linguistic Differences in the Grammaticalization of Future Time Reference Influence Intertemporal Choices 下载免费PDF全文
According to Chen's (2013) Linguistic Savings Hypothesis (LSH), our native language affects our economic behavior. We present three studies investigating how cross‐linguistic differences in the grammaticalization of future‐time reference (FTR) affect intertemporal choices. In a series of decision scenarios about finance and health issues, we let speakers of altogether five languages that represent FTR with increasing strength, that is, Chinese, German, Danish, Spanish, and English, choose between hypothetical sooner‐smaller and later‐larger reward options. While the LSH predicts a present‐bias that increases with FTR‐strength, our decision makers preferred later‐larger options and this future‐bias increased with FTR‐strength. In multiple regressions, the FTR‐strength effect persisted when controlled for socioeconomic and cultural differences. We discuss why our findings deviate from the LSH and ask in how far the FTR‐strength effect represents a habitual constitution of linguistic relativity or an instance of online decision framing. 相似文献

Our Followers Are Lions,Theirs Are Sheep: How Social Identity Shapes Theories About Followership and Social Influence 下载免费PDF全文
Niklas K. Steffens S. Alexander Haslam Jolanda Jetten Frank Mols 《Political psychology》2018,39(1):23-42
Two studies examine how self‐categorization theory can be used to refine our understanding of people's implicit theories about followership and social influence. Results from Study 1 show that perceivers regard followers of a group they themselves identify strongly with (rather than not at all) to be more representative of the prototype of effective followers (displaying enthusiasm, industry, good citizenship) and to be less representative of the antiprototype of effective followers (displaying conformity, incompetence, and insubordination). Results are replicated in a second experiment in which we compare the views of those self‐categorizing as either Republican or Democrat responding to followers of the Republican and Democratic Party. Results of Study 2 replicate those of Study 1 and also reveal qualitative differences in the preferred influence strategy for dealing with followers. Specifically, respondents seek to engage in persuasion when trying to change the behavior of ingroup followers, while resorting to coercion when trying to change the behavior of outgroup followers. Our results are the first to provide evidence that perceivers' theories about what followers are like and how they are influenced most effectively are structured by perceivers' identification (and dis‐identification) with the particular groups that leaders are championing. 相似文献

Despite vaccines' consistently demonstrated effectiveness, vaccination rates remain suboptimal due to vaccine refusal. Low vaccination rates are particularly problematic for individuals who cannot be vaccinated for medical reasons and thus must rely on herd immunity (i.e., protection of vulnerable individuals due to the high rate of vaccination of other—often socially distant—individuals). The current study uses a novel decision‐making task to examine how three variables impacted participants' highest acceptable probability of side effects to their children: 1) the severity of the side effects their children experience, 2) the social distance to the beneficiary of the vaccination, and 3) the probability that the vaccine will prevent disease for that designated beneficiary. Participants' willingness to risk potential side effects of vaccination systematically decreased as the 1) effectiveness of the vaccination decreased, 2) the beneficiary of the vaccination became more socially distant, and 3) the severity of side effects increased. These data were well‐described by behavioral economic models used to examine the discounting of other health behavior. 相似文献

Impulsive choice and pre‐exposure to delays: iv. effects of delay‐ and immediacy‐exposure training relative to maturational changes in impulsivity 下载免费PDF全文

Impulsive choice describes preference for smaller, sooner rewards over larger, later rewards. Excessive delay discounting (i.e., rapid devaluation of delayed rewards) underlies some impulsive choices, and is observed in many maladaptive behaviors (e.g., substance abuse, gambling). Interventions designed to reduce delay discounting may provide therapeutic gains. One such intervention provides rats with extended training with delayed reinforcers. When compared to a group given extended training with immediate reinforcers, delay‐exposed rats make significantly fewer impulsive choices. To what extent is this difference due to delay‐exposure training shifting preference toward self‐control or immediacy‐exposure training (the putative control group) shifting preference toward impulsivity? The current study compared the effects of delay‐ and immediacy‐exposure training to a no‐training control group and evaluated within‐subject changes in impulsive choice across 51 male Wistar rats. Delay‐exposed rats made significantly fewer impulsive choices than immediacy‐exposed and control rats. Between‐group differences in impulsive choice were not observed in the latter two groups. While delay‐exposed rats showed large, significant pre‐ to posttraining reductions in impulsive choice, immediacy‐exposed and control rats showed small reductions in impulsive choice. These results suggest that extended training with delayed reinforcers reduces impulsive choice, and that extended training with immediate reinforcers does not increase impulsive choice. 相似文献

In the grip of fear: Dissociations in attentional processing of animal fearful individuals 下载免费PDF全文
Sandra C. Soares Francisco Esteves Daniel Lundqvist 《Scandinavian journal of psychology》2015,56(1):11-17
Using a modified attention paradigm we investigated specific attentional mechanisms in processing animal feared stimuli. In this paradigm arrays of four pictures were displayed and after its disappearance from view a probe (a letter, X or P) then followed unpredictably in the location of one of the four pictures. The results showed that discriminations of probes tended to be impeded by spider stimuli, compared to snake stimuli. This effect was potentiated by high anxiety but only for those individuals fearful of spiders, since no such effect was observed for snake fearful individuals. Moreover, the discrimination of the probes was not facilitated when presented after the feared stimuli. The implications of these findings are discussed as a function of the cognitive bias involved in specific fear. 相似文献

Individual differences with regard to speed preference may be a source of speed heterogeneity and conflicts in traffic, such as tailgating and dangerous overtaking. The main aim of the current study was to explore drivers’ speed preferences when driving for different reasons (saving money on fuel, driving safely, driving for fun or driving as usual) and the relationship of these preferences to observed speeds and self-reported speed. 193 drivers were interviewed at five different locations, and were asked about their speeds on roads they had just travelled. Drivers’ speeds on these roads were also sampled with a speed gun. The results showed large differences between speeds chosen for different driving purposes; the lowest speeds were chosen when the goal was economy and the highest when driving for fun. In addition, there were individual differences in speed preferences such that some drivers indicated that their usual speed was above what they believed was a safe speed while others indicated that they usually drove even slower than what they thought was safe. These differences may account for much of the speed heterogeneity observed in on-road behaviour. The results also showed that drivers’ speed choices are highly influenced by their usual speeds, even more so than their beliefs regarding what constitutes a safe speed, which may help explain non-compliance with speed limits. No relationship was found between speed choice and risk perception. 相似文献
