In the field of creativity, psychologists typically only study humans and biologists or ethologists usually focus either on animal problem solving or consider creativity to be an evolutionary adaptation. Yet a fuller application of creativity principles to animal behavior may both shed insight into animal cognition and expand current notions of creativity. We propose a framework for animal creativity based both on animal behavior research and creativity theories. The framework proposes different creative capabilities required for each level—i.e., one does not have to complete level 2 to reach level 3, however one does have to possess higher creative abilities. The first level is the simple ability to recognize novelty. Next is observational learning, which raises questions about imitation, intention of behavior, and the cultural transmission of creative behaviors. At the peak is creating a tool or a behavior with the specific understanding that is new and different.  相似文献

This study assessed whether previously reported sex differences in jealousy could be accounted for by other related emotions. Participants were presented with hypothetical scenarios involving both a sexual and an emotional infidelity, then were asked how jealous, angry, hurt, and disgusted they would be (using continuous scales). The results replicate the sex difference in response to sexual and emotional infidelity, demonstrate that it is robust when continuous measures are used, and confirm that it is unique to jealousy. Sex differences did not emerge for anger, hurt, or disgust. Instead, sexual infidelity elicited greater anger and disgust, and less hurt, than emotional infidelity, for both women and men. The results also suggest that it is the jealous response to an emotional infidelity that best discriminates women from men, and that both women and those participants in a serious, committed relationship reported significantly greater intensity in their emotional reactions, as compared to men and those not in a committed relationship.  相似文献

Poor medication adherence is a leading cause of excessive cardiovascular morbidity among African Americans. Many adherence-promoting interventions have addressed economic barriers, improved the patient-provider relationship, simplified regimens, and used reminder systems; however, the problem of low adherence remains intractable. Meanwhile, positive psychological attributes that might serve to promote medication adherence have not been fully explored. To address this gap, we examined the association between happiness and medication adherence among low-income African Americans with hypertension treated in a safety-net setting. Data were obtained from the Alabama Collaboration for Cardiovascular Equality, 2007?C2008. Happiness was measured using the 4-item scale of Lyubomirsky and Lepper; low, moderate, and high happiness were defined by tertiles because of the non-normal distribution. Medication adherence was assessed with the Morisky Medication Adherence Scale. Associations were quantified with ordinal logistic regression. Our sample of 573 African Americans was 71.6?% female and had an average age?±?SD of 53.6?±?9.7?years and a median happiness score of 5.2. Compared to participants with low happiness, the odds (OR; 95?% CI) of being in a better medication adherence category were greater for those with moderate (1.53; 1.02?C2.27) and high (2.26; 1.52-3.37) happiness, after adjusting for age, sex, income, education, and difficulty paying for medical care. Within this cohort of low-income African Americans with hypertension, participants with greater happiness exhibited better medication adherence. Although one interpretation of our study is that more adherent patients are naturally happier, our findings raise the possibility that adding happiness-boosting components may increase the effectiveness of more traditional adherence interventions.  相似文献

Adults appear to recognize that different memory sharing contexts, such as telling a story to a friend at a party versus providing eyewitness testimony, vary in their accuracy demands and adjust their retellings accordingly. There is less evidence that children are able to make the same distinctions. In the present two‐part experiment, we first tested 6–8‐year‐old children's beliefs about the accuracy requirements of different memory sharing contexts that varied on the listener's implicit expectation about accuracy. Children were then read a short story and were given retelling instructions that emphasized accuracy or entertainment. Results from the first task indicated that children evidence a significant truth bias, suggesting that they believe accurate retellings are preferred regardless of context. Despite this, children did appear to adjust their retellings as a function of context, with retellings in the high accuracy condition including more verbatim and less error statements. Finally, children who evidenced a stronger truth bias were less likely to employ the language of storytelling by producing lower‐quality narratives. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

Drawing on evolutionary psychology, social exchange styles were conceptualized in terms of two dimensions of individual differences in approaching exchange relationships: Benefit‐seeking and cost‐vigilance. In Study 1, a principal components analysis of the Social Exchange Styles Questionnaire (SESQ) in 156 undergraduates confirmed the presence of two dimensions that were very similar to the expected dimensions: Equitable alliance building (EAB) and vigilant alliance management (VAM). The SESQ scales showed good internal consistency and construct validity. Multiple regressions confirmed that social exchange styles were distinct from other personality variables. In Study 2, multilevel modelling conducted on 45 small work groups demonstrated that EAB positively predicted members' subjective performance, while VAM positively predicted objective performance. Theoretical questions and future research directions are discussed. Copyright © 2010 John Wiley & Sons, Ltd.  相似文献

We tested the hypothesis that conceptual similarity promotes generalization of conditioned fear. Using a sensory preconditioning procedure, three groups of subjects learned an association between two cues that were conceptually similar, unrelated, or mismatched. Next, one of the cues was paired with a shock. The other cue was then reintroduced to test for fear generalization, as measured by the skin conductance response. Results showed enhanced fear generalization that correlated with trait anxiety levels in the group that learned an association between conceptually similar stimuli. These findings suggest that conceptual representations of conditional stimuli influence human fear learning processes.  相似文献

Individuals with anxiety disorders demonstrate altered cognitive performance including (1) cognitive biases towards negative stimuli (affective biases) and (2) increased cognitive rigidity (e.g., impaired conflict adaptation) on affective Stroop tasks. Threat of electric shock is frequently used to induce anxiety in healthy individuals, but the extent to which this manipulation mimics the cognitive impairment seen in anxiety disorders is unclear. In this study, 31 healthy individuals completed an affective Stroop task under safe and threat-of-shock conditions. We showed that threat (1) enhanced aversive processing and abolished a positive affective bias but (2) had no effect on conflict adaptation. Threat of shock thus partially models the effects of anxiety disorders on affective Stroop tasks. We suggest that the affective state of anxiety—which is common to both threat and anxiety disorders—modulates the neural inhibition of subcortical aversive processing, whilst pathologies unique to anxiety disorders modulate conflict adaptation.  相似文献

Cyber technology provides a new venue for the expression of aggression. However, whether cyber technology has produced a new group of peer aggressors or simply allowed aggressive peers new tools to victimize others is unclear. This study sampled 1,672 adolescents to assess their engagement in cyber aggression. Although "cyber," "overt," and "relational" represent distinct subtypes of aggressive behavior, our results indicate that adolescents' behaviors clustered according to their frequency-not type-of aggression. Thus cyber technology provides new tools for youth who already engage in aggressive behaviors in the physical world to victimize peers in cyberspace.  相似文献

A functional analysis identified the reinforcer maintaining feces throwing and spitting exhibited by a captive adult chimpanzee (Pan troglodytes). The implementation of a function-based treatment combining extinction with differential reinforcement of an alternate behavior decreased levels of inappropriate behavior. These findings further demonstrate the utility of function-based approaches to assess and treat behavior problems exhibited by captive animals.  相似文献
