AbstractThis paper considers two objections based in axiological considerations against the position that whether a given outcome, or possible future or world, is morally worse than a second world may depend in part on what is going on at a third world. Such a wide-angled approach to determining worseness is critical to the solution I have previously proposed in connection with the nonidentity problem. I argue that both objections fail. 相似文献

Genetic and Environmental Pathways Underlying Personality Traits and Perceived Stress: Concurrent and Longitudinal Twin Studies 下载免费PDF全文
The present study examined the genetic and environmental etiology underlying the Big Five personality traits and perceived stress, concurrently and longitudinally. In study 1, we used the twin sample from the National Longitudinal Study of Adolescent to Adult Health (Add Health IV) data. The results indicated that about 70% of the association between the Big Five personality traits and perceived stress was due to genetic influences. In study 2, we used the twin sample from the Midlife in the United States Survey (MIDUS I and II) to examine the genetic and environmental influences underlying the longitudinal relations between the Big Five personality traits and perceived stress. The results suggested that continuity in perceived stress was primarily accounted for by genetic influences, and changes in perceived stress were mainly due to nonshared environmental influences. The continuity in the association between the five personality traits and perceived stress was largely accounted for by genetic factors, and nonshared environmental factors made greater contributions to changes in the association between personality traits and perceived stress. Among the Big Five personality traits, the genetic components in conscientiousness and neuroticism made substantial contributions to the genetic link between personality traits and perceived stress across both studies.

Name learning strategies including retrieval practice, semantic associations and imagery were compared in laboratory‐based and real‐life experiments. Experiments 1 and 2 studied expanding retrieval practice and a semantic association strategy as memory improvement techniques for learning proper names. Participants either retrieved or restudied names on the same, expanding schedule. After a short, filled interval, cued recall of names was about 250% better following retrieval than restudy and 200% better with than without semantic associations. Together, the techniques improved recall by 300–400%. In Experiment 3, retrieval practice was compared with an imagery mnemonic for name learning under real‐life social conditions: Participants sought to learn the names of people they met at a party. Retrieval practice produced 50% higher recall after 24–72 hours but the imagery mnemonic was no more effective than non‐directed instructions to learn names.

Three‐ to nine‐year‐old children (n=144) interacted with a photographer and were interviewed about the event either a week or a month later. The informativeness and accuracy of information provided following either open‐ended or direct rapport building were compared. Children in the open‐ended rapport‐building condition provided more accurate reports than children in the direct rapport‐building condition after both short and long delays. Open‐ended rapport‐building led the three‐ to four‐year‐olds to report more errors in response to the first recall question about the event, but they went on to provide more accurate reports in the rest of the interview than counterparts in the direct rapport‐building condition. These results suggest that forensic interviewers should attempt to establish rapport with children using an open‐ended style. Published in 2004 by John Wiley & Sons, Ltd. 相似文献

The burgeoning world-wide consumer culture brings with it certain baggage. Materialistic attitudes and compulsive buying have
both been linked to lower levels of subjective well-being in consumers. Additionally, time is becoming an increasingly precious
commodity as denizens of the consumer culture increase their work load and activities in an attempt to fully achieve the happiness
promised by a lifestyle of consumption. The purpose of the present research is to investigate whether the negative impact
of materialism and compulsive buying on well-being is moderated by a person’s perceived time affluence (the time one perceives
he/she has available for life’s many activities). Using a large sample of adolescents (n = 1,329), the present study finds that (1) materialism and compulsive buying negatively impact subjective well-being, and
that (2) time affluence moderates the relationship between materialism and compulsive buying and well-being. Specifically,
perceptions of time affluence were found to negate the negative relationship between both materialism and SWB and compulsive
buying and SWB. And (3), the present research appears to have uncovered a “sweet spot” when it comes to the influence of time
affluence on the above relationships. Too little or too much time affluence was found to be associated with lower well-being.
A simple slope analysis suggests that moderate levels of time affluence are most conducive to our well-being as consumers.
In addition to discussing these findings, the authors also note certain limitations and offer directions for future research. 相似文献

With the present data, we explored the relations between the language of interviewer questions, children's reports, and case and child characteristics in forensic interviews. Results clearly indicated that the type of questions posed by interviewers—either probing generic or episodic features of an event—was related to the specificity of information reported by children. Further, interviewers appeared to adjust their questioning strategies based on the frequency of the alleged abuse. Children alleging single instances of abuse were asked more episodic questions than those alleging multiple abuses. In contrast, children alleging multiple incidents of abuse were asked a greater proportion of generic questions. Given that investigators often seek forensically relevant episodic information, it is recommended that training for investigators focus on recognition of prompt selection tendencies and developing strategies for posing non‐suggestive, episodically focused questions.

Separate cognitive processes govern the inhibitory control of manual and oculomotor movements. Despite this fundamental distinction, little is known about how these inhibitory control processes relate to more complex domains of behavioral functioning. This study sought to determine how these inhibitory control mechanisms relate to broadly defined domains of impulsive behavior. Thirty adults with attention-deficit/hyperactivity disorder (ADHD) and 28 comparison adults performed behavioral measures of inhibitory control and completed impulsivity inventories. Results suggest that oculomotor inhibitory control, but not manual inhibitory control, is related to specific domains of self-reported impulsivity. This finding was limited to the ADHD group; no significant relations between inhibitory control and impulsivity were found in comparison adults. These results highlight the heterogeneity of inhibitory control processes and their differential relations to different facets of impulsivity. 相似文献

The effect of Internet use on social relationships is still a matter of intense debate. This study examined the relationships between use of social media (instant messaging and social network sites), network size, and emotional closeness in a sample of 117 individuals aged 18 to 63 years old. Time spent using social media was associated with a larger number of online social network "friends." However, time spent using social media was not associated with larger offline networks, or feeling emotionally closer to offline network members. Further, those that used social media, as compared to non-users of social media, did not have larger offline networks, and were not emotionally closer to offline network members. These results highlight the importance of considering potential time and cognitive constraints on offline social networks when examining the impact of social media use on social relationships. 相似文献

Integrated what-where-when memory, sometimes called 'episodic-like' memory, has been shown to occur in a number of animals, including food-storing birds and rodents. It is not always clear in these studies, however, what aspect of "when" is remembered. We examined memory for what, where, and when in black-capped chickadees Poecile atricapillus in a procedure designed to dissociate memory for elapsed time (how long ago) from memory for a point in time, the sense of "when" implied in most discussions of episodic or episodic-like memory. Chickadees searched for food in multiple trials that each involved a two-phase procedure. In Phase 1, birds found preferred mealworms in half the sites on one side of an aviary and less preferred sunflower seeds in half the sites on the other side of the aviary. In Phase 2, following a retention interval, birds searched in the aviary with fresh sunflower seeds placed in the sites that held seeds in Phase 1 but either fresh or degraded mealworms in the sites that held mealworms in Phase 1. Whether a site held fresh or degraded worms depended on either when during the day Phase 1 had occurred (Group When), how long ago Phase 1 had occurred (Group HLA), or both (Group When + HLA). Chickadees in all three groups were able to discriminate where and when palatable worms were to be found, but there were temporal limitations on the use of HLA and When + HLA cues that were not found for the use of When cues. 相似文献
