Self‐injurious behavior (SIB), such as self‐biting and head banging, has been reported to occur in approximately 10% of captive, individually housed nonhuman primates. Accounts of the etiology of SIB in primates range from ecological to physiological. However, to date, no research has examined the possible influence of social consequences delivered by handlers and keepers in the maintenance of SIB in this population. The current study investigated the effects of social contact as a potentially reinforcing consequence for the SIB displayed by an olive baboon (Papio hamadryas anubis). Results indicated that the behavior was maintained by attention from humans. As treatment, reinforcement was arranged for an appropriate alternative response, resulting in increases in the appropriate alternative behavior and decreases in SIB. 相似文献

Traditionally, liberals have confined religion to the sphere of the ‘private’ or ‘non-political’. However, recent debates
over the place of religious symbols in public spaces, state financing of faith schools, and tax relief for religious organisations
suggest that this distinction is not particularly useful in easing the tension between liberal commitments to equality on
the one hand, and freedom of religion on the other. This article deals with one aspect of this debate, which concerns whether
members of religious communities should receive exemptions from regulations that place a distinctively heavy burden on them.
Drawing on Habermas’ understanding of churches as ‘communities of interpretation’, we explore possible alternatives to both
the ‘rule-and-exemption’ approach and the ‘neutralist’ approach. Our proposal rests on the idea of mutual learning between
secular and religious perspectives. On this interpretation, what is required is (i) the generation and maintenance of public
spaces in which there could be discussion and dialogue about particular cases, and (ii) evaluation of whether the basic conditions
of moral discourse are present in these spaces. Thus deliberation becomes a touchstone for the building of a shared democratic
ethos. 相似文献

During the first year of life, infants begin to have difficulties perceiving non‐native vowel and consonant contrasts, thus adapting their perception to the phonetic categories of the target language. In this paper, we examine the perception of a non‐segmental feature, i.e. stress. Previous research with adults has shown that speakers of French (a language with fixed stress) have great difficulties in perceiving stress contrasts ( Dupoux, Pallier, Sebastián & Mehler, 1997 ), whereas speakers of Spanish (a language with lexically contrastive stress) perceive these contrasts as accurately as segmental contrasts. We show that language‐specific differences in the perception of stress likewise arise during the first year of life. Specifically, 9‐month‐old Spanish infants successfully distinguish between stress‐initial and stress‐final pseudo‐words, while French infants of this age show no sign of discrimination. In a second experiment using multiple tokens of a single pseudo‐word, French infants of the same age successfully discriminate between the two stress patterns, showing that they are able to perceive the acoustic correlates of stress. Their failure to discriminate stress patterns in the first experiment thus reflects an inability to process stress at an abstract, phonological level. 相似文献

Eavesdropping can be defined as the extraction of information from the interactions between other individuals. It provides
a relatively cheap way of gathering relevant information for fitness enhancement. Here, we propose that obligate avian brood
parasites, which always lay their eggs in foreign nests of individuals of other species, may eavesdrop on their host sexual
signals to locate nests of high quality individuals in which to lay their parasitic eggs. Sexual signal variation can honestly
signal parental quality. Thus, by eavesdropping on sexual signals, parasites may select high quality foster parents for their
own offspring. Such a use of sexual signals within host populations by brood parasites differs from signal exploitation theory
that proposes that parasite only use signals to locate potential host independently from signaller quality. Here, we review
the avian literature concerning host choice within a host species by obligate avian brood parasites and find evidence for
host selection within individuals of a host species on the basis of cues potentially functioning as sexually selected traits,
or at least revealing parental abilities. We have also found support for the existence of benefits linked to host selection
by avian brood parasites. Finally, one study reported on the attenuation of a sexual ornament in host populations under strong
pressure by brood parasites. Most of these findings have been interpreted as evidence for host selection by avian brood parasites
based on the conspicuousness of sexual signals. We suggest, however, that these findings may in fact reveal eavesdropping
on host signalling performance by brood parasites which would use the information extracted to choose the better individuals
among conspecifics of a given host. This provides a new perspective for the study of host selection in obligate brood parasites,
and raises interesting questions for the study of animal cognition that would deserve experimental studies. 相似文献

A pilot study was carried out in university students to evaluate the effect of a health promotion program for eating disturbances and body dissatisfaction. A subgroup of 135 medical students of both sexes in their second year was selected. There were divided in three groups, high-risk students (EDI > 40) and low-risk students (EDI < 40) who participated in the program and nonparticipants as comparison group. Program had a total of 16 workshops of 90 min. A year later the different assessment measurements were compared, body image, attitudes and eating behaviours, psychopathological levels and self-esteem. Differences by gender were found on the impact of the intervention. The program presented a statistical significant improvement in body-image satisfaction, eating attitudes only in high-risk female students in the intervention group. This pilot program for eating disorder prevention in university populations can be considered effective, mainly in female populations at risk for developing an eating disorder. 相似文献

The Relations of Temperament and Emotion Self-regulation with Suicidal Behaviors in a Clinical Sample of Depressed Children in Hungary 总被引:1,自引:0,他引:1

Although major depressive disorder (MDD) is associated with suicidal behaviors, some depressed individuals are not suicidal and others evidence various forms of suicidality. We thus investigated whether aspects of temperament and self-regulation of dysphoria represent risk factors for DSM-IV suicidality (recurrent thoughts of death, recurrent suicidal ideation, suicidal plan, and suicide attempt) in depressed youths. Using a sample of children with MDD (N = 407; ages 7-14 years), recruited from clinical sites across Hungary, we tested the hypotheses that: (a) suicidality is related to higher levels of trait negative emotionality as well as more maladaptive and fewer adaptive regulatory responses to dysphoria and (b) as the severity of suicidal behavior increases, levels of trait negative emotionality and dysfunctional emotion regulation also increase. We also explored if other aspects of temperament relate to suicidality. Children's DSM-IV diagnoses were based on semi-structured interviews and best-estimate psychiatric consensus. Parents independently provided ratings of their children's temperament, and children separately completed an inventory of emotion regulation (ER). Using multivariate models, we failed to confirm the hypothesized relations of negative trait emotionality and suicidality, but confirmed that high maladaptive and low adaptive ER response tendencies increase the odds of suicidal behaviors, above and beyond the risk posed by depressive illness severity. Unplanned interaction terms between temperament dimensions (other than negative emotionality) and ER suggested that at some high-extremes of temperament, ER has no impact on suicidality but in their absence, adaptive ER lowers the risk of suicidality. The practical implications of the findings are discussed. 相似文献

Separate mechanisms recruited by exogenous and endogenous spatial cues: evidence from a spatial Stroop paradigm 总被引:1,自引:0,他引:1
Funes MJ Lupiáñez J Milliken B 《Journal of experimental psychology. Human perception and performance》2007,33(2):348-362
The present experiments tested whether endogenous and exogenous cues produce separate effects on target processing. In Experiment 1, participants discriminated whether an arrow presented left or right of fixation pointed to the left or right. For 1 group, the arrow was preceded by a peripheral noninformative cue. For the other group, the arrow was preceded by a central, symbolic, informative cue. The 2 types of cues modulated the spatial Stroop effect in opposite ways, with endogenous cues producing larger spatial Stroop effects for valid trials and exogenous cues producing smaller spatial Stroop effects for valid trials. In Experiments 2A and 2B, the influence of peripheral noninformative and peripheral informative cues on the spatial Stroop effect was directly compared. The spatial Stroop effect was smaller for valid than for invalid trials for both types of cues. These results point to a distinction between the influence of central and peripheral attentional cues on performance and are not consistent with a unitary view of endogenous and exogenous attention. 相似文献

Spiritist Hospital Chaplaincy in Brazil has been growing significantly in recent years, with the implementation of new services through the work of Spiritist Medical Associations (SMAs) in different regions of the country. This article describes the importance of historical interconnections from the advent of spiritism in the world and its introduction in Brazil to the emergence of Spiritist Hospital Chaplaincy in our country and presents the documented experience over 5 years of spiritist chaplain care, in the period from 2012 to 2016, guided by the SMA of Piracicaba at the Unimed Hospital of Piracicaba (São Paulo). We documented 41,914 visits to 13,983 inpatients and an analysis of these records allowed us to reflect on the importance of this service and confirm its expansion and acceptance by different contemporary religious beliefs. 相似文献

The concept of polarity is pervasive in natural language. It relates syntax, semantics and pragmatics narrowly (Giannakidou, in: Maienborn, von Heusinger, Portner (eds.), Semantics: an international handbook of natural language meaning, De Gruyter Mouton, Berlin, 2011; Israel in The grammar of polarity: pragmatics, sensitivity, and the logic of scales, Cambridge studies in linguistics, Cambridge University Press, Cambridge, 2014), it refers to items of many syntactic categories such as nouns, verbs and adverbs. Neutral polarity items appear in affirmative and negative sentences, negative polarity items cannot appear in affirmative sentences, and positive polarity items cannot appear in negative sentences. A way of reasoning in Natural Language is through Natural Logic (van Benthem in Essays in logical semantics, vol. 29 of Studies in linguistics and philosophy, Reidel, Dordrecht, 1986; Language in action: categories, lambdas, and dynamic logic, vol. 130 of Studies in logic, Elsevier, Amsterdam, 1991). This logic is based on the concept of polarity in order to make the meaning of a sentence weaker o stronger without changing its truth value. There exist many proposals to compute polarity in the Natural Logic context, the most widely known are the ones by: van Benthem (1986, 1991), Sánchez-Valencia (Studies on natural logic and categorial grammar, Ph.D. thesis, Universiteit van Amsterdam, 1991), Dowty (Proceedings of the 4th conference on semantics and theoretical linguistics, Cornel University, CLC Publications, Rochester, 1994), and van Eijck (in: ten Cate, Zeevat (eds.), 6th international Tbilisi symposium on logic, language, and computation, Batumi, Georgia, Springer, 2007). If Natural Logic is going to be used, as an inferential mechanism between text fragments, in Natural Language Processing applications such as text summarization, question answering, and information extraction, it is a priority to know what the existing relationship among the aforementioned algorithms is; for example, to implement the most general. We show in this paper the equivalence among the analyzed algorithms, filling a gap in Natural Logic research, particularly in computing polarity, and the soundness of their algorithms. 相似文献
