Humans have the capacity to use stimuli interchangeably by forming equivalence classes, and this ability seems to be supported by our language system. According to Sidman and Tailby (Conditional discrimination vs. matching to sample: an expansion of the testing paradigm. J Exp Anal Behav 37:5–22, 1982), the formation of equivalence classes require that three relations are derived among the class members, and past experiments have shown that one of these relations, i.e., symmetry, corresponding to the ability to reverse a relation (if A → B, then B → A), is extremely difficult to obtain in non-human animals. Because language development and the ability to form equivalence classes both co-occur in children with an increased ability to form categories, the current study tested the idea that category learning might promote symmetry in a nonhuman primate species. In Experiment 1, twelve Guinea baboons (Papio papio) were trained to associate 60 pictures of bears and 60 pictures of cars to two category labels, before being tested in symmetry trials. In Experiment 2, symmetry was trained and tested by reversing the association order between labels and pictures, using a new set of stimuli. In both experiments, the baboons successfully demonstrated category discrimination, but had only a weak (though significant) tendency to respond in accordance with symmetry during test trials. Altogether, our results confirm that symmetry is inherently difficult in non-human animals. We discuss possible explanations for such a limitation and give reasons for thinking that the effects of categorization on symmetry should be further investigated. 相似文献

Non-human animals, including great apes, have been suggested to share some of the skills for planning that humans commonly exhibit. A crucial difference between human and non-human planning may relate to the diversity of domains and needs in which this skill is expressed. Although great apes can save tools for future use, there is little evidence yet that they can also do so in other contexts. To investigate this question further, we presented the apes with a planning token-exchange task that differed from standard tool-use tasks. Additionally, we manipulated the future outcome of the task to investigate planning flexibility. In the Exchange condition, subjects had to collect, save and transport tokens because they would need them 30 min later to exchange them for food with a human, i.e., “bring-back” response. In the Release condition, the collection and transport of tokens were not needed as no exchange took place after 30 min. Out of 13 subjects, eight solved the task at least once in the Exchange condition, with chimpanzees appearing less successful than the other species. Importantly, three individuals showed a clear differential response between conditions by producing more “bring-back” responses in the Exchange than in the Release conditions. Those bonobo and orangutan individuals hence adapted their planning behavior according to changing needs (i.e., they brought tokens back significantly more often when they would need them). Bonobos and orangutans, unlike chimpanzees, planned outside the context of tool-use, thus challenging the idea that planning in these species is purely domain-specific. 相似文献

Knowing which properties of visual displays facilitate statistical reasoning bears practical and theoretical implications. Therefore, we studied the effect of one property of visual diplays?– iconicity (i.e., the resemblance of a visual sign to its referent)?– on Bayesian reasoning. Two main accounts of statistical reasoning predict different effect of iconicity on Bayesian reasoning. The ecological-rationality account predicts a positive iconicity effect, because more highly iconic signs resemble more individuated objects, which tap better into an evolutionary-designed frequency-coding mechanism that, in turn, facilitates Bayesian reasoning. The nested-sets account predicts a null iconicity effect, because iconicity does not affect the salience of a nested-sets structure—the factor facilitating Bayesian reasoning processed by a general reasoning mechanism. In two well-powered experiments (N = 577), we found no support for a positive iconicity effect across different iconicity levels that were manipulated in different visual displays (meta-analytical overall effect: log OR = ?0.13, 95 % CI [?0.53, 0.28]). A Bayes factor analysis provided strong evidence in favor of the null hypothesis—the null iconicity effect. Thus, these findings corroborate the nested-sets rather than the ecological-rationality account of statistical reasoning. 相似文献

Following a previous investigation of religio‐spiritual beliefs in American Indians, this article examined prevalence and correlates of religio‐spiritual participation in two tribes in the Southwest and Northern Plains (N = 3,084). Analysis suggested a “religious profile” characterized by strong participation across three traditions: aboriginal, Christian, and Native American Church. However, sociodemographic variables that have reliably predicted participation in the general American population, notably gender and age, frequently failed to achieve significance in multivariate analyses for each tradition. Religio‐spiritual participation was strongly and significantly related to belief salience for all traditions. Findings suggest that correlates of religious participation may be unique among American Indians, consistent with their distinctive religious profile. Results promise to inform researchers’ efforts to understand and theorize about religio‐spiritual behavior. They also provide tribal communities with practical information that might assist them in harnessing social networks to confront collective challenges through community‐based participatory research collaborations. 相似文献

Previous research about coping with the stigma of mental illness mostly relied on cross‐sectional or qualitative research designs. In the present study, the consequences of ten identity management strategies for mental illness stigma were observed in a longitudinal design. Cross‐lagged analyses were used to describe the influence of the strategies on the frequency of stigma experiences and on mental health in a two‐wave panel of people with mental illness (n = 367, 79% repeated response rate). Selective disclosure and information seeking emerged as adaptive identity management strategies, whereas overcompensation and withdrawal led to lower mental health. Results were mostly unaffected by demographic and psychiatric variables. The results support an empowerment model of stigma resilience that portrays stigmatized people as active constructors of their social world. 相似文献

Prolonged stress (≥ six months) may cause a condition which has been named exhaustion disorder (ED) with ICD‐10 code F43.8. ED is characterised by exhaustion, cognitive problems, poor sleep and reduced tolerance to further stress. ED can cause long term disability and depressive symptoms may develop. The aim was to construct and evaluate a self‐rating scale, the Karolinska Exhaustion Disorder Scale (KEDS), for the assessment of ED symptoms. A second aim was to examine the relationship between self‐rated symptoms of ED, depression, and anxiety using KEDS and the Hospital Anxiety and Depression Scale (HAD). Items were selected based on their correspondence to criteria for ED as formulated by the Swedish National Board of Health and Welfare (NBHW), with seven response alternatives in a Likert‐format. Self‐ratings performed by 317 clinically assessed participants were used to analyse the scale's psychometric properties. KEDS consists of nine items with a scale range of 0–54. Receiver operating characteristics analysis demonstrated that a cut‐off score of 19 was accompanied by high sensitivity and specificity (each above 95%) in the discrimination between healthy subjects and patients with ED. Reliability was satisfactory and confirmatory factor analysis revealed that ED, depression and anxiety are best regarded as different phenomena. KEDS may be a useful tool in the assessment of symptoms of Exhaustion Disorder in clinical as well as research settings. There is evidence that the symptom clusters of ED, anxiety and depression, respectively, reflect three different underlying dimensions. 相似文献

The current study examined whether carrying objects in one's hands influenced different parameters associated with independent locomotion. Specifically, 14- and 24-month-olds walked in a straight path under four conditions of object carriage – no object (control), one object carried in one hand (one object-one hand), two objects carried in each of the hands (two objects-two hands), and one object carried in both hands simultaneously (one object-two hands). Although carrying objects failed to influence a variety of kinematic parameters of gait, it did affect children's arm postures, with children adopting less mature arm positions when carrying objects. Finally, arm position was related to walking skill, but only for older children when they were not carrying objects. These findings indicate that although a relation does exist between arm positions and gait parameters, this relation is easily disrupted by carrying loads, even small ones. 相似文献

This study investigated students' decision‐making processes in a knowledge‐assessing multiple‐choice (MC) test using eye‐tracking methodology. More precisely, the gaze bias effect (more attention to more preferred options) and its relation to domain knowledge were the focus of the study. Eye movements of students with high (HPK) and low (LPK) prior domain knowledge were recorded while they solved 21 MC items. Afterwards, students rated every answer option according to their subjective preference. As expected, both HPK and LPK students showed a gaze bias towards subjectively preferred answer options, whereby HPK students spent more time on objectively correct answers. Furthermore, a fine‐grained time‐course analysis showed similar patterns of attention distribution over time for both HPK and LPK students, when focusing on subjective preference levels. Thus, these data offer a new perspective on knowledge‐related MC item solving and provide evidence for the generalizability of the gaze bias effect across decision tasks.

This paper contributes to a recent call for dialogue between the different professional groups representing psychotherapy in Europe. At present, two core psychotherapy groups exist in Europe, namely the EAP, representing psychotherapy, and EFPA, representing psychologists specialising in psychotherapy. This article compares and contrasts two competency frameworks representative of these bodies, which capture the skills, knowledge, reasoning and values of the respective professions. The shared and divergent competencies are identified and discussed, followed by suggestions for potential changes in future European competency frameworks. By doing this, we not only respond to the recent call for dialogue but also promote collaboration and discussion between the professional groups representing psychotherapeutic practice both in Europe and beyond. 相似文献
