New Caledonian crows are reported to have impressive pandanus-tool manufacture abilities. These claims are based on an extensive artefact record. However, inferring behavioural and cognitive abilities without direct observation of tool manufacture is problematic. Here we report (and document on video) direct observations of a crow making and using stepped pandanus tools at Pic Ningua. We observed (1) a bias for making tools on left edges consistent with that previously found at the site, (2) faithful manufacture of a stepped design with high overall congruence in the shapes of tools, (3) the use of convergent rips to first form the tapered end working away from the trunk then the wide end working towards the trunk, (4) appropriate functional use of stepped tools by use of the leaf-edge barbs to hook food from holes, and (5) consistent holding of tools on the left side of its head when using them. Our observations verify most of the claims based on the artefact record, but the crows exact manufacture technique was slightly different to that inferred previously.Electronic Supplementary Material Supplementary material is available in the online version of this article at 相似文献

Dissemination, the second stage of Experimental Social Innovation and Dissemination (ESID) is a critical, if not defining, element of this social change model. This paper attempts to assess the extent to which community psychology has adopted and implemented ESID's dissemination focus in its training and publications. We identify four levels of commitment to dissemination: dissemination advocate, dissemination activist, dissemination researcher, and experimental dissemination researcher. Content analyses of textbooks, journal publications, and conference papers and a brief survey of doctoral training in the field were conducted. Findings suggest that the dissemination aspects of ESID have been modestly and partially implemented within the field. That is, although there is some evidence of a commitment to dissemination practice (advocate, activist), there is much less evidence of a commitment to dissemination research. The implications of these findings for the effectiveness of the ESID model and for training and practice in community psychology are discussed. 相似文献

The purpose of this study was to evaluate changes in behaviors and behavioral intentions that occurred among 342 middle-age women (M age 49.5 yr.) after participating in an Osteoporosis Prevention Program. The valid and reliable Osteoporosis Preventing Behaviors Survey (developed by Doheny and Sedlak) and a survey developed for this work were measures. Significant changes in behaviors were reported, especially increases in weight-bearing physical activity, dairy product intake, and decreases in consumption of caffeine-containing beverages. Many subjects reported intentions to increase physical activity and calcium intake. An Osteoporosis Prevention Program may help promote osteoporosis prevention behaviors, but intents must be followed up to check actual change. 相似文献

The D (dissemination) phase of the ESID model has been often overlooked in our efforts to create innovative and widespread social change. The process of replicating successful social innovations is both a prerequisite for dissemination (in order to assess the consistency of effects) and an obvious outcome of a successful dissemination effort. Fidelity, the extent to which a replicated program is implemented in a manner consistent with the original program model, is an important dimension of replication. This study was designed to provide empirical data related to three questions. Can complex social programs be implemented with fidelity? How much fidelity is appropriate or desired? What are the organizational dynamics of adoption with fidelity? Data were collected from grantees of a national replication initiative funded by the Center for Substance Abuse Prevention. Data suggest that high fidelity can be achieved, at least in the context in which programs are mandated to do so as part of the funding agreement and are given technical assistance in achieving fidelity. Secondly, programs perceived high fidelity as having positive effects on the program and its participants, a finding consistent with a limited assessment of the relationship of program outcomes and fidelity. Finally, much was learned about the human and organizational dynamics of replicating with fidelity. Implications for policy and direction regarding replication are discussed. 相似文献

The authors investigated the effects of cutting specific graphic scenes of film violence on self-reports of arousal, enjoyability, and perceptions of violence among a sample of U.S. students. In 3 studies, they varied film exposure from 1 1/2 min in the 1st study to a complete motion picture (American vs. British version of same film) in the 3rd. In all 3 studies, the participants rated the cut versions as less violent than the uncut versions. The participants distinguished quite subtle differences in levels of violence, even when the cuts were minor and contextualized within an entire movie. Cutting the movie significantly increased its enjoyability for the women; for the men, there was no significant difference. Cutting violent films made no difference in arousal for the men but substantially lowered self-report levels of arousal for the women. 相似文献

This paper reports the results of three tasks comparing the development of the understanding of facial expressions of emotion in deaf and hearing children. Two groups of hearing and deaf children of elementary school age were tested for their ability to match photographs of facial expressions of emotion, and to produce and comprehend emotion labels for the expressions of happiness, sadness, anger, fear, disgust, and surprise. Accuracy data showed comparable levels of performance for deaf and hearing children of the same age. Happiness and sadness were the most accurately matched expressions and the most accurately produced and comprehended labels. Anger was the least accurately matched expression and the most poorly comprehended emotion label. Disgust was the least accurately labeled expression; however, deaf children were more accurate at labeling this expression, and also at labeling fear, than hearing children. Error data revealed that children confused anger with disgust, and fear with surprise. However, the younger groups of deaf and hearing children also showed a tendency to confuse the negative expressions of anger, disgust, and fear with sadness. The results suggest that, despite possible differences in the early socialisation of emotion, deaf and hearing children share a common understanding of the emotions conveyed by distinctive facial expressions. 相似文献

This study explored relationships between “highly probable” neuropathology in the limbic system (as gauged by clinically elevated
scores on the Limbic System Check-list-33, or LSCL-33, a screening index for limbic system dysfunction developed by medical
researchers at Harvard and Dartmouth) and inventoried psychopathology (as gauged through scores on the MMPI) among a group
of adjudicated pedophiles incarcerated for treatment in a specialized prison for criminal sexual psychopaths in a mid-Atlantic
state. Principal findings: Only 33 percent of this sample of incarcerated pedophiles exhibits scores on the LSCL-33 at a level high enough to warrant
a medical conclusion of “probable” limbic system dysfunction. When scores on the MMPI are grouped according to critical values
for clinically relevant scores on the LSCL-33, significant F ratios in one-way analyses of variance are observed on L, F,
K, Hs, D, Hy, Pa, Pt, Sc, and Ma. Mean T scores for “probable” dysfunctionals simultaneously reach elevations at or above
the threshold of clinical significance for Pd, Pa, and Sc. On that basis, the categorization psychopathic paranoid schizophrenia readily applies to limbic system dysfunctional child sexual abusers studied in this inquiry, but not to their nondysfunctional
counterparts. But significant F ratios are observed neither for the age of the victim(s) in the instant offense(s), for the
number of prior arrests for sex offenses, for the number of prior arrests for any and all felony offenses, including sex offenses,
nor for the offender's current age. However, a stepwise multiple regression between gross number of prior arrests for any
and all offenses (including sex offenses) as the most robust of the indices of past criminal activity and both LSCL-33 and
MMPI scores across all offenders represented in this inquiry (i.e., the limbic system dysfunctional, the nondysfunctional,
and a mid-range group) proceeds to four steps, achieving a multiple R of .575 and encompassing Pd, Mf, Pa, and LSCL-33 scores
as the most efficient interactive post-dictive set. Stepwise multiple regression analyses of past arrest record computed independently
for limbic system dysfunctionals and nondysfunctionals progresses among dysfunctionals to seven steps, achieving a multiple
R of .867 and encompassing Pd, Hy, Ma, Mf, Si, Pa, and Sc scores as the most efficient interactive post-dictive set; and among
nondysfunctionals, to six steps, achieving a multiple R of .797 and encompassing Mf, D, Pt, Hy, Pa, and over-controlled hostility
scores as the most efficient interactive post-dictive set. The latter results are interpreted as suggesting that neuropathology
and psychopathology interact with and potentiate each other in post-dicting criminal behavior among the pedophiles studied
in this inquiry.

On the basis largely of interview data, this article outlines a working model for a process psychology paradigm for the heroic rescue fantasy and contrasts a prototypi-cal sequence therefore with corresponding sequences in antisocial, asocial, and prosocial risk-taking. It proposes that the heroic rescue fantasy emerges from the interplay between (a) neurologic anomaly affecting realistic assessment of costs, risks, and benefits associated with behavior of various sorts, (b) perpetuating as impulsivity expressed as persistent underestimation of costs and risks and perhaps supported by a condition of alexithymia or verbal deficit in cognitive functioning, interacting with (c) a persistent need for self-aggrandizement likely born of psychosocial developmental experiences, leading to (d) sensitization to interpersonal environments that provide role models for and positively reinforce prosocial risk-taking behavior, yielding to (e) the manipulative creation of an opportunity to behave in such fashion as to engender risk to others and to the self, and eventuating (f) in the enactment of a heroic rescue that prevents harm to others and thus elicits praise, admiration, adulation, and possibly formal reward. The conjunction between impulsivity expressing itself in the underesti-mation of costs (neurogenic or not) and need for self-aggrandizement is proposed as necessary in the heroic rescue fantasy, the manipulative creation of an opportunity to behave that engenders risk to others and to the self is proposed as the defining behavior, and a rescue that prevents harm to others is proposed as the defining crite-rion. 相似文献

We have used a combined genetic and pharmacological approach to define the time course of the requirement for protein kinase A (PKA) and protein synthesis in long-term memory for contextual fear conditioning in mice. The time course of amnesia in transgenic mice that express R(AB) and have genetically reduced PKA activity in the hippocampus parallels that observed both in mice treated with inhibitors of PKA and mice treated with inhibitors of protein synthesis. This PKA- and protein synthesis-dependent memory develops between 1 hr and 3 hr after training. By injecting the protein synthesis inhibitor anisomycin or the PKA inhibitor Rp-cAMPs at various times after training, we find that depending on the nature of training, contextual memory has either one or two brief consolidation periods requiring synthesis of new proteins, and each of these also requires PKA. Weak training shows two time periods of sensitivity to inhibitors of protein synthesis and PKA, whereas stronger training exhibits only one. These studies underscore the parallel dependence of long-term contextual memory on protein synthesis and PKA and suggest that different training protocols may recruit a common signaling pathway in distinct ways. 相似文献
