This paper examined the performance of dingoes (Canis dingo) on the rope-pulling task, previously used by Miklósi et al. (Curr Biol 13:763–766, 2003) to highlight a key distinction in the problem-solving behaviour of wolves compared to dogs when in the company of humans. That is, when dogs were confronted with an unsolvable task, following a solvable version of the task they looked back or gazed at the human, whereas, wolves did not. We replicated the rope-pulling task using 12 sanctuary-housed dingoes and used the Miklósi et al. (Curr Biol 13:763–766, 2003) definition of looking back behaviour to analyse the data. However, at least three different types of look backs were observed in our study. We, then developed a more accurate operational definition of looking back behaviour that was task specific and reanalysed the data. We found that the operational definition employed greatly influences the results, with vague definitions potentially overestimating the prevalence of looking back behaviour. Thus, caution must be taken when interpreting the results of studies utilising looking back as behaviour linked to assistance seeking during problem solving. We present a more stringent definition and make suggestions for future research. 相似文献

The authors’ aim was to determine which variables allow for the characterization of motor balance behavior. Traditional measures and nonlinear measures of center of pressure (COP; n = 30) and kinematics (n = 10) were tested in their absolute and relative consistency in a 30-s standing balance task protocol under stable and unstable conditions. Regarding COP variables, mean velocity (mVel), permutation entropy (PE) and detrended fluctuation analysis (DFA) exhibited high consistency between trials and ranked individuals more accurately compare with other metrics. In the kinematic signal mVel, PE and DFA had good intrasession reliability values in unstable conditions. Overall, the intrasession reliability values were better in the unstable condition than in the stable condition and the measures calculated using derived data had better intrasession reliability values. In conclusion, mVel, PE, and DFA allow for the good characterization of motor balance behavior in a simplified protocol where velocity time series are analyzed. 相似文献

This article explores twelve short narrative films created by women and trans people living with disabilities and embodied differences. Produced through Project Re?Vision, these micro documentaries uncover the cultures and temporalities of bodies of difference by foregrounding themes of multiple histories: body, disability, maternal, medical, and/or scientific histories; and divergent futurities: contradictory, surprising, unpredictable, opaque, and/or generative futures. We engage with Alison Kafer's call to theorize disability futurity by wrestling with the ways in which “the future” is normatively deployed in the service of able‐bodiedness and able‐mindedness (Kafer 2013 ), a deployment used to render bodies of difference as sites of “no future” (Edelman 2004 ). By re‐storying embodied difference, the storytellers illuminate ongoing processes of remaking their bodily selves in ways that respond to the past and provide possibilities for different futures; these orientations may be configured as “dis‐topias” based not on progress, but on new pathways for living, uncovered not through evoking the familiar imaginaries of curing, eliminating, or overcoming disability, but through incorporating experiences of embodied difference into time. These temporalities gesture toward new kinds of futures, giving us glimpses of ways of cripping time, of cripping ways of being/becoming in time, and of radically re‐presencing disability in futurity. 相似文献

Positron emission tomography studies during speech have indicated a failure to show the normal activation of auditory cortical areas in stuttering individuals. In the present study, P300 event-related potentials were used to investigate possible effects of behavioral treatment on the pattern of signal amplitude and latency between waves. In order to compare variations in P300 measurements, a control group paired by age and gender to the group of stutterers, was included in the study. Findings suggest that the group of stutterers presented a significant decrease in stuttering severity after the fluency treatment program. Regarding P300 measurements, stutterers and their controls presented results within normal limits in all testing situations and no significant statistical variations between pre and post treatment testing. When comparing individual results between the testing situations, stutterers presented a higher average decrease in wave latency for the right ear following treatment. The results are discussed in light of previous P300 event-related potentials and functional imaging studies with stuttering adults.Educational objectives: The reader will learn about and be able to describe the: (1) use of P300 event-related potentials in the study of stuttering; (2) differences between stuttering and non-stuttering adults; and (3) effects of behavioral fluency treatment on cerebral activity in stuttering speakers. 相似文献

In this cross-sectional study we analyzed the links between marital quality and intimacy, body image, and psychological quality
of life (PQoL) of breast cancer patients, as well as the moderating role of cancer phase (treatment, survivorship) on the
aforementioned links. We also evaluated whether body image mediated the associations between marital relationship variables
and PQoL. An analysis of the data from 128 patients (66 undergoing treatment, 62 survivors) indicated that the majority of
links between variables were significant only during the treatment phase. Mediating effect of body image on the associations
between relationship variables and PQoL was found only at the treatment phase. 相似文献

The persistence of gender inequality in postindustrial societies is puzzling in light of a plethora of changes that destabilize it, including shifts in economy, legislation, and the proliferation of feminist politics. In family relations, such persistence manifests as a disconnect between couples aspiring to be more egalitarian yet continuing to enact traditional gender roles and hierarchies. There is an emerging consensus that gender inequality persists because of people's continued reliance on sexist ideology or gendered assumptions that constitute women as innately distinct from and inferior to men. Sexist ideology changes its form to accommodate to changing socio‐economic conditions. Contemporary forms of sexism are old ways of legitimizing male power articulated in new and creative ways, often by incorporating feminist arguments. To effectively recognize and address “new sexism,” scholars and practitioners require new, innovative research frameworks. Our objective in writing this article is two‐fold. First, we seek to advance discursive (i.e., focused on language in use) approaches to the study of sexism. Second, we present the results of a discursive analysis of “new” sexist discourse in the context of couple therapy. The study provides preliminary evidence that, despite endorsing egalitarian norms, couples studied continue to rely on gender binaries and remain entrenched in old‐fashioned patterns of gender inequality. Implications of these results for the practice of couple therapy and for future research are discussed. 相似文献

The present study aimed to utilize a Receiver Operating Characteristic (ROC) approach in order to improve clinical decision-making for adolescents at risk for the development of psychopathology in the aftermath of a natural disaster. Specifically we assessed theoretically-driven individual, interpersonal, and event-related vulnerability factors to determine which indices were most accurate in forecasting PTSD. Furthermore, we aimed to translate these etiological findings by identifying clinical cut-off recommendations for relevant vulnerability factors. Our study consisted of structured phone-based clinical interviews with 2000 adolescent-parent dyads living within a 5-mile radius of tornados that devastated Joplin, MO, and northern Alabama in Spring 2011. Demographics, tornado incident characteristics, prior trauma, mental health, and family support and conflict were assessed. A subset of youth completed two behavioral assessment tasks online to assess distress tolerance and risk-taking behavior. ROC analyses indicated four variables that significantly improved PTSD diagnostic efficiency: Lifetime depression (AUC = .90), trauma history (AUC = .76), social support (AUC = .70), and family conflict (AUC = .72). Youth were 2–3 times more likely to have PTSD if they had elevated scores on any of these variables. Of note, event-related characteristics (e.g., property damage) were not related to PTSD diagnostic status. The present study adds to the literature by making specific recommendations for empirically-based, efficient disaster-related PTSD assessment for adolescents following a natural disaster. Implications for practice and future trauma-related developmental psychopathology research are discussed. 相似文献

Pigeon and human subjects were given repeated choices between variable and adjusting delays to token reinforcement that titrated in relation to a subject's recent choice patterns. Indifference curves were generated under two different procedures: immediate exchange, in which a token earned during each trial was exchanged immediately for access to the terminal reinforcer (food for pigeons, video clips for humans), and delayed exchange, in which tokens accumulated and were exchanged after 11 trials. The former was designed as an analogue of procedures typically used with nonhuman subjects, the latter as an analogue to procedures typically used with human participants. Under both procedure types, different variable‐delay schedules were manipulated systematically across conditions in ways that altered the reinforcer immediacy of the risky option. Under immediate‐exchange conditions, both humans and pigeons consistently preferred the variable delay, and indifference points were generally ordered in relation to relative reinforcer immediacies. Such risk sensitivity was greatly reduced under delayed‐exchange conditions. Choice and trial‐initiation response latencies varied directly with indifference points, suggesting that local analyses may provide useful ancillary measures of reinforcer value. On the whole, the results indicate that modifying procedural features brings choices of pigeons and humans into better accord, and that human—nonhuman differences on risky choice procedures reported in the literature may be at least partly a product of procedural differences. 相似文献

Two experiments examined whether time‐based prospective memory performance is influenced by the continuous or discontinuous nature of an ongoing activity. The first experiment demonstrated that prospective memory performance was not influenced by the engagement in continuous or discontinuous ongoing activity. The second experiment demonstrated that a discontinuous ongoing activity negatively affected prospective memory performance when participants had to execute two time‐based tasks for which the retention intervals partially overlapped. The results suggest that when individuals are engaged in multiple time‐based tasks, a general timing disruption occurs, with a proactive interference effect resulting in costs that are detrimental to prospective timing.
