There are few indulgences academics can crave more than to have their work considered and addressed by leading researchers in their field. We have been fortunate to have two outstanding philosophers from whose work we have learned a great deal give ours their thoughtful attention. Grappling with Stephen Yablo’s, and Juan Comesaña’s comments and criticisms has helped us gain a better understanding of our ideas as well as their shortcomings. We are extremely grateful to them for the attentiveness and seriousness with which they have considered our arguments and to philosophical studies for giving us this opportunity. Given the substantive difference between the two response papers, there is not much beyond sincere gratitude that we can covey to them jointly. We will therefore address them in turn. 相似文献

We describe SwarmSight (available at https://github.com/justasb/SwarmSight), a novel, open-source, Microsoft Windows software tool for quantitative assessment of the temporal progression of animal group activity levels from recorded videos. The tool utilizes a background subtraction machine vision algorithm and provides an activity metric that can be used to quantitatively assess and compare animal group behavior. Here we demonstrate the tool’s utility by analyzing defensive bee behavior as modulated by alarm pheromones, wild-bird feeding onset and interruption, and cockroach nest-finding activity. Although more sophisticated, commercial software packages are available, SwarmSight provides a low-cost, open-source, and easy-to-use alternative that is suitable for a wide range of users, including minimally trained research technicians and behavioral science undergraduate students in classroom laboratory settings. 相似文献

Theories of semantic memory differ in the extent to which relationships among concepts are captured via associative or via
semantic relatedness. We examined the contributions of these two factors, using a visual world paradigm in which participants selected the named object from a four-picture display. We controlled for semantic relatedness while
manipulating associative strength by using the visual world paradigm’s analogue to presenting asymmetrically associated pairs
in either their forward or backward associative direction (e.g., ham—eggs vs. eggs—ham). Semantically related objects were preferentially fixated regardless of the direction of presentation (and the effect size
was unchanged by presentation direction). However, when pairs were associated but not semantically related (e.g., iceberg—lettuce), associated objects were not preferentially fixated in either direction. These findings lend support to theories in which
semantic memory is organized according to semantic relatedness (e.g., distributed models) and suggest that association by
itself has little effect on this organization. 相似文献

The present study related generational status, marital status, parental overprotection (control), and cultural value conflict to self-esteem and depression among first and second-generation Asian Indian immigrant women in the south-midwestern United States. Self-report data from 73 community-dwelling women supported the hypotheses that unmarried and second-generation women would report greater maternal control and cultural value conflict than would married and first-generation women. Second-generational status, high maternal control, and high cultural value conflict correlated with higher depressive symptomology; being married, low maternal control, and low cultural value conflict were related to high self-esteem. Regression analyses indicated a mediating role for cultural value conflict for depression symptom predictors, but not for self-esteem predictors. Open-ended response data provided enriched understanding of these women’s cultural and family conflicts. 相似文献

The spread of endemic school violence in the United States from urban black, Hispanic, and other minority areas to white suburbia and smaller communities has alarmed the nation. Contrary to common belief, the incidence of school violence has been fairly stable except in the areas of violence against females and gang membership. The culture of violence and easy availability of guns is a major contributing factor. The relationship between school violence, suicidality and psychiatric disorders, specifically depressive disorders, conduct disorder, and alcohol and drug abuse are discussed within the framework of the psychological autopsy of suicide in children and adolescents. There are striking similarities between acts of school violence and suicidality. Specific guidelines are provided regarding clinical assessment of potentially violent youth with emphasis on exploration of attachment behavior in various developmental stages. 相似文献

Eleven first grade and 10 second grade students, all with reading and behavioral difficulties, received one-on-one tutoring using the Sound Partners reading program (Vadasy & Pool, l997). Students received 30 min of tutoring each day for 5 months. Students were assessed on Letter-Word Identification, Passage Comprehension, and Word Attack subtests of the Woodcock-Johnson-Revised (WJ-R): Tests of Achievement. An informal measure (rapid letter naming) was also used. Results indicated that gains of approximately 1 standard deviation (or greater) were noted for subtests of the WJ-R for first-grade students; second graders showed relatively stable performance from pre- to posttest assessments. Similar performance was noted on the informal measure across grades. Program satisfaction data showed that overall the tutors, teachers, and students were pleased with the program. Discussion focuses on the implications for future investigations. 相似文献
