In several species, the ability to locate a disappearing object is an adaptive component of predatory and social behaviour.
In domestic dogs, spatial memory for hidden objects is primarily based on an egocentric frame of reference. We investigated
the geometric components of egocentric spatial information used by domestic dogs to locate an object they saw move and disappear.
In experiment 1, the distance and the direction between the position of the animal and the hiding location were put in conflict.
Results showed that the dogs primarily used the directional information between their own spatial coordinates and the target
position. In experiment 2, the accuracy of the dogs in finding a hidden object by using directional information was estimated
by manipulating the angular deviation between adjacent hiding locations and the position of the animal. Four angular deviations
were tested: 5, 7.5, 10 and 15°. Results showed that the performance of the dogs decreased as a function of the angular deviations
but it clearly remained well above chance, revealing that the representation of the dogs for direction is precise. In the
discussion, we examine how and why domestic dogs determine the direction in which they saw an object disappear. 相似文献

This study evaluates the effectiveness of dialectical behaviour therapy (DBT) for borderline personality disorder (BPD) in an unselected, comorbid population seeking 3-month inpatient treatment. We studied 50 consecutively admitted individuals (44 women, six men) with BPD as defined by DSM-IV at three time points (at admission, at discharge, and at the 15-month follow-up). For the clinical diagnoses, we used the Structured Clinical Interview for DSM-IV (SCID) and compared the frequencies of comorbid axis I and axis II disorders at admission and at the 15-month follow-up. Overall, participants showed a high degree of comorbidity. Psychopathology was significantly reduced at post-treatment and at follow-up. Effect sizes for outcome measures were within the range of those of previous studies. Our findings support the notion that the results of the DBT efficacy research can be generalized to an inpatient setting and to patients with BPD disorder with high comorbidity. 相似文献

This study compared nonverbal numerical processing in 6-year-olds with that in nonhuman animals using a numerical bisection task. In the study, 16 children were trained on a delayed match-to-sample paradigm to match exemplars of two anchor numerosities. Children were then required to indicate whether a sample intermediate to the anchor values was closer to the small anchor value or the large anchor value. For two sets of anchor values with the same ratio, the probability of choosing the larger anchor value increased systematically with sample number, and the psychometric functions superimposed when plotted on a logarithmic scale. The psychometric functions produced by the children also superimposed with the psychometric functions produced by rhesus monkeys in an analogous previous experiment. These examples of superimposition demonstrate that nonverbal number representations, even in children who have acquired the verbal counting system, are modulated by Weber's law. 相似文献

Intimate partner abuse (or relationship abuse) against women is recognised as a major public health issue. A number of relationship abuse prevention programs targeted at youth have been developed in Australia. These programs are generally aimed at changing attitudes, and take the stance that girls should not be viewed as being responsible for protecting themselves against violence. In this paper it is argued that the current, dominant focus on physical violence, over other forms of relationship abuse, limits the potential effectiveness of programs that might otherwise help young people to resist the development of abusive dynamics. It is also argued that programs that presume a victim status for girls and a perpetrator status for boys are both inconsistent with contemporary evidence and unlikely to empower young people at risk of chronic perpetration and/or victimisation to avoid such outcomes. A dyadic slippery slope model of chronic relationship abuse is proposed and new directions for prevention research in this area are suggested. 相似文献

An algorithm for the growth of two-dimensional Penrose tiling, based on symmetry operations on a seed rhombus, is discussed and demonstrated. Independent of empirical matching rules, as suggested by Penrose [Bull. Inst. Math. Appl. 10 266 (1974)], and also overcoming the scaling-down operation, as proposed by Ramachandrarao et al. (Acta Crystallogr. A 47 210 (1991)], the present algorithm follows a mechanism akin to self-assembly and can be continued ad infinitum. 相似文献

People who need help can be reluctant to seek it. This can be due to social image concerns. Here, we investigate if these concerns may be prompted by a salient negative meta‐stereotype: the belief that one's group is judged negatively by another group. Specifically, we researched group members' help‐seeking behaviour in the context of a dependency‐related meta‐stereotype. In a two‐condition study (N = 45), we manipulated participants' belief that their national group was judged dependent by a significant out‐group. We then examined their subsequent help‐seeking behaviour on a real‐world task. Participants whose social identity as a group member was salient showed greater reluctance to seek help when the meta‐stereotype was made prominent compared with when it was not. This suggests that, in a context where social image and social identity concerns are relevant, group members are willing to sacrifice the possibility of accessing needed help in order to avoid confirming a negative stereotype of their group. The implications of these results for helping transactions and community development are discussed. Copyright © 2012 John Wiley & Sons, Ltd. 相似文献

In a study to extend the theory of cognitive dissonance into the area of person perception, 108 male freshmen dormitory students were led to believe that they either would or would not be sharing a room in the future with a negative other. They were also informed that they were either low, moderate, or high in similarity to this negative other. The major response measure was the extent to which the negative first impression changed in a more positive direction. A 2 × 3 ANOVA showed that both the proximity and similarity manipulations had the predicted effect. However, the trend in similarity was not linear, as hypothesized. Similarity was also found to be a more salient source of dissonance than proximity. 相似文献

In this paper I have described a short-psychotherapy treatment with a mother, a 3-year-old girl, and occasionally a father, over the difficulty in separating and settling down at nursery. The mother's unresolved mourning for the early miscarriage of her second baby was one important factor. She held on to the company and comfort provided by the little girl, who had become the vessel of maternal projections. Filled with Poppy's projections, the mother had also felt unable to withstand and process them. Mr Green was a conflictual element in the family, rather than a supportive husband and father, and Poppy's care and problems were left with the mother. Nine sessions unblocked the situation and allowed Poppy to settle down at a private nursery. 相似文献

ABSTRACTAt present, the consequences and functions of experiences of shame are not yet well understood. Whereas psychology literature typically portrays shame as being bad for social relations, motivating social avoidance and withdrawal, there are recent indications that shame can be reinterpreted as having clear social tendencies in the form of motivating approach and social affiliation. Yet, until now, no research has ever put these alternative interpretations of shame-motivated behaviours directly to the test. The present paper presents such a test by studying the extent to which shame motivates a preference for social withdrawal versus a preference for social approach. Two studies (N?=?148 and N?=?133) using different shame inductions both showed people experiencing shame to prefer to be together with others (social approach) over being alone (social withdrawal). In addition, the preference for a social situation was found to be unique for shame; it was not found for the closely related emotion of guilt. Taken together, these findings provide direct empirical support for the idea that shame can have positive interpersonal consequences. 相似文献

As an alternative to using the concepts of emotion, fear, anger, and the like as scientific tools, this article advocates an approach based on the concepts of core affect and psychological construction, expanding the domain of inquiry beyond “emotion”. Core affect is a neurophysiological state that underlies simply feeling good or bad, drowsy or energised. Psychological construction is not one process but an umbrella term for the various processes that produce: (a) a particular emotional episode's “components” (such as facial movement, vocal tone, peripheral nervous system change, appraisal, attribution, behaviour, subjective experience, and emotion regulation); (b) associations among the components; and (c) the categorisation of the pattern of components as a specific emotion. 相似文献
