Gaze following allows individuals to detect the locus of attention of both conspecifics and other species. However, little
is known about how this ability develops. We explored the emergence of bobwhite quail hatchlings’ ability to track human gaze
by assessing their avoidance behavior in an open arena under five testing conditions: (1) a Direct Gaze condition, in which
an experimenter looking down was positioned above one of two approach areas; (2) a Gaze Follow condition in which an experimenter,
positioned equidistant between two approach areas, directed his/her gaze towards one of the areas; (3) a Masked Gaze Follow
condition, in which the experimenter wore a mask during the Gaze Follow test; (4) a Deprived Face Experience condition, in
which hatchlings were deprived of experience with human faces prior to the Gaze Follow test; and (5) a Control condition in
which no experimenter was present during testing. Results revealed that hatchlings from the Direct Gaze condition preferred
the non-gazed approach area at all ages tested. Hatchlings from the Gaze Follow condition preferred the non-gazed approach
area at 48 and 72 h, but not at 24 h of age. In contrast, hatchlings from the Masked Gaze Follow, Deprived Face and Control
conditions did not prefer either approach area at any age tested. These results indicate that experience with human faces
plays a key role in the rapid emergence of gaze following behavior in bobwhite quail hatchlings. 相似文献

This article presents the Spanish adaptation of the Affective Norms for English Words (ANEW; Bradley & Lang, 1999). The norms are based on 720 participants' assessments of the translation into Spanish of the 1,034 words included in the ANEW. The evaluations were done in the dimensions of valence, arousal and dominance using the Self-Assessment Manikin (SAM). Apart from these dimensions, five objective (number of letters, number of syllables, grammatical class, frequency and number of orthographic neighbors) and three subjective (familiarity, concreteness and imageability) psycholinguistic indexes are included. The Spanish adaptation of ANEW can be downloaded at www.psychonomic.org. 相似文献

This article is a response to Josh Reeves's recent book Against Methodology in Science and Religion: Recent Debates on Rationality and Theology that welcomes Reeves's proposal for an anti-essentialist future for the field of science-and-religion, particularly because it has the potential to move the field beyond current, well-worn methods: the dominance of Christian theology and doctrine, the importance of credibility strategies, and the dependence upon philosophical discourses. Reeves’ proposal has the potential to open the science-and-religion field to other topics, problems, and methods, such as studying lived science-and-religion. One way of doing this is to study popular culture and its artifacts such as literature, which portrays a co-mingling of religion and science at the level of day-to-day experiences and practices of characters. For at the level of lived experience, religion and science are not well-defined disciplines neatly compartmentalized into separate academic departments. 相似文献

The clinical presentation of multiple sclerosis (MS) with psychiatric symptoms is uncommon but it is believed that MS patients are twice as likely to be afflicted with bipolar disorder as the general population. We report two cases (mother and daughter) of MS presenting with bipolar disorder in the form of recurrent manic psychosis and whose outcome was favourable with neuroleptics and corticosteroids. In both cases we found multiple hypersignal lesions on brain magnetic resonance imaging (MRI), especially in the right frontal lobe where we observed signs of activity. Apart from clinical and radiological concordance, the patients exhibited similar class I HLA alleles and identical class II HLA alleles. We focused discussion on whether there may be a common genetic susceptibility to both illnesses or whether MS caused psychiatric manifestations. The coincidence of psychiatric and neurological symptoms in most relapses supports the second hypothesis. 相似文献

Using self‐monitoring and differential reinforcement of low rates of behavior to decrease repetitive behaviors: A case study 下载免费PDF全文
We used a reversal design to evaluate the effects of a self‐monitoring system and differential reinforcement of low rates of behavior on decreasing repetitive body movements in a child with autism. A trial‐based functional analysis revealed that repetitive body movements were maintained by automatic reinforcement. Treatment consisted of teaching the participant to use a self‐monitoring system to monitor the occurrence of repetitive body movements. A stimulus control analysis revealed the self‐monitoring system acquired stimulus control over the repetitive body movements, in that they were more likely to occur in the absence of the system than in its presence. The self‐monitoring system was implemented with a differential reinforcement of low rates of behavior, and their combined effects were evaluated within a reversal design. Repetitive body movements decreased with the implementation of the treatment. The use of self‐monitoring systems to target problem behavior is discussed. 相似文献

As part of a continuous process to explore the factors that might weaken or corrupt traditional peer review, in this paper, we query the ethics, fairness and validity of the request, by editors, of authors to suggest peer reviewers during the submission process. One of the reasons for the current crisis in science pertains to a loss in trust as a result of a flawed peer review which is by nature biased unless it is open peer review. As we indicate, the fact that some editors and journals rely on authors’ suggestions in terms of who should peer review their paper already instills a potential way to abuse the trust of the submission and publishing system. An author-suggested peer reviewer choice might also tempt authors to seek reviewers who might be more receptive or sympathetic to the authors’ message or results, and thus favor the outcome of that paper. Authors should thus not be placed in such a potentially ethically compromising situation, especially as a mandatory condition for submission. However, the fact that they do not have an opt-out choice during the submission process—especially when using an online submission system that makes such a suggestion compulsory—may constitute a violation of authors’ rights. 相似文献

The principal goal of this study was to verify whether it was possible to obtain both aversive and appetitive electrodermal classical conditioning, using pictures as conditioned stimuli (CS), and unconditioned stimuli (US). Additionally, we tried to verify whether, as a consequence of such conditioning, diminution of the unconditioned response (UR) was observed. With this aim, IAPS (?International Affective Picture System?) pictures were selected as stimuli. A picture showing a burnt face was used as the aversive US (USav), and a picture showing a scene with erotic content was used as the appetitive US (USap). As the aversive CS (CSav), and appetitive CS (CSap), two images with intermediate values of valence and arousal showing male faces were selected. In the experimental group, 10 CSav/USav and 10 CSap/USap trials were presented. In the control group 10 CSav, CSap, USav, and USap trials were presented in pseudorandom order. Skin conductance response (SCR) elicited by both the CSs and the USs was scored. Results showed aversive conditioning, but neither appetitive conditioning nor UR diminution. Problems to obtain conditioning using pictures as stimuli and possible options to overcome them in future research are discussed. 相似文献

Sleep problems are prevalent among Veterans. Left untreated, such problems may elevate psychological distress and increase risk of subsequent mental health disorders. Psychological resilience may buffer against negative psychological outcomes, yet the relationship between sleep and resilience has not been studied. This study explored poor sleep, resilience, and psychological distress using questionnaires collected as part of the Study of Post-Deployment Mental Health. Participants (N = 1,118) had served in the US military since September 11, 2001, had one or more overseas deployments, and were free from a past-month DSM-defined mental health disorder. Hierarchical linear regression was used to examine the association between poor sleep quality (Pittsburgh Sleep Quality Index total score) and psychological distress (Global Symptom Index; Symptom Checklist-90-R), controlling for demographic and health characteristics. Moderation analyses tested for a potential buffering effect of resilience (Connor-Davidson Resilience Scale). Poor sleeping Veterans had worse physical and psychological health, lower resilience, and endorsed more lifetime traumatic events. Poor sleep was associated with greater psychological distress controlling for health and demographic characteristics. Both resilience factors—adaptability and self-efficacy—had significant buffering effects on the relationship between poor sleep and psychological distress, suggesting that resilience may protect against negative outcomes in poor sleepers. Additional research is warranted to better understand the relationships between sleep, resilience, and psychological distress. Such research may inform pertinent prevention efforts, including interventions that improve sleep, enhance resilience, and protect against incident mental health diagnoses. 相似文献
