The evolutionary theory of behavior dynamics is a complexity theory that instantiates the Darwinian principles of selection, reproduction, and mutation in a genetic algorithm. The algorithm is used to animate artificial organisms that behave continuously in time and can be placed in any experimental environment. The present paper is an update on the status of the theory. It includes a summary of the evidence supporting the theory, a list of the theory's untested predictions, and a discussion of how the algorithmic operations of the theory may correspond to material reality. Based on the evidence reviewed here, the evolutionary theory appears to be a strong candidate for a comprehensive theory of adaptive behavior. 相似文献

The purpose of the current study was to examine the effects of mand, tact, and native‐to‐foreign (NFI) and foreign‐to‐native (FNI) intraverbal training on the acquisition of a foreign language. We used a multiple‐baseline design across participants with an embedded adapted alternating treatments design to compare the effects of mand training, tact training, NFI training, and FNI training on the acquisition rate of Chinese words in four typically developing adults. We also examined the emergence of untrained foreign language responses for each training condition. Data for 3 out of the 4 participants suggest that mand training was the most efficient training procedure with respect to acquisition rate. The greatest amount of emergent responding was observed for the mand and tact training conditions. 相似文献

Drawing on appraisal theories of discrete emotions, we propose and test a model in which abusive supervision directed toward oneself and toward work unit peers (coworker abusive supervision) are interactively related to generalized feelings of shame, anger, and fear. These discrete emotions, in turn, tend to precipitate distinct responses that do not directly target the supervisor. We tested our hypotheses with a three-wave, time-lagged survey of 285 full-time workers from 55 work units. Consistent with our theorizing, supervisory abuse was associated with stronger feelings of shame while at work when the abusive supervision reported by one's coworkers was lower (vs. higher), whereas abuse had a stronger association with anger when coworkers also perceived relatively high levels of abuse. The distinct action tendencies associated with shame and anger are related to employees engaging in less voice behavior and more interpersonal deviance, respectively, and fear is related to higher turnover intentions. We discuss the study's implications for theory development concerning abusive supervision. 相似文献

Studies have shown the existence of inter-individual differences in choice behavior, some people seeking for the best (maximizers) and others for a good enough option (satisficers). Here, we explored whether these inter-individual differences are influenced by aging and common personality traits (i.e., Big Five model). Young (n = 125; 19 years old) and elderly adults (n = 101; 86 years old) completed different scales assessing – among others – maximization and Big Five traits. Our results indicated a greater proportion of maximizers in elderly than in young adults. We also found a minor association between maximization and Big Five traits in both groups. In sum, aging influences choice behavior, but this cannot be explained by changes of common personality traits. 相似文献

The influence of shared enjoyment and positive affect (PA) on resilient thinking was examined in 191 middle‐aged adults (40–65 years), participating in a study of resilience. Participants completed diaries assessing positive events, shared enjoyment, PA, and resilient cognitions (RC). Multilevel structural equation modeling was utilized to examine when and who engages in RC. Participants reported more RC on days they experienced more positive experiences. This relationship was explained by shared enjoyment and PA. Level‐1 proportional reduction of variance (PRV) for shared enjoyment, PA, and RC was 9%, 10%, and 35%, respectively. Individuals reporting more positive experiences trended toward a more resilient mindset; PA accounted for this relationship. Shared enjoyment mediated the relationship between interpersonal events and PA. These findings suggest PA is integral to having a resilient mindset, and shared enjoyment is a potential mechanism that may influence PA. Level‐2 PRV for shared enjoyment, PA, and RC was 22%, 21%, and 55%, respectively. RC were associated with less depression and anxiety; and greater well‐being, vitality, and physical functioning at follow‐up. 相似文献

HIV/AIDS‐related (HAR) stigma is still a prevalent problem in Sub‐Saharan Africa, and has been found to be related to mental health of HIV‐positive individuals. However, no studies in the Sub‐Saharan African context have yet examined the relationship between HAR stigma and mental health among HIV‐negative, HIV‐affected adults and families; nor have any studies in this context yet examined stigma as an ecological construct predicting mental health outcomes through supra‐individual (setting level) and individual levels of influence. Multilevel modeling was used to examine multilevel, ecological relationships between HAR stigma and mental health among child and caregiver pairs from a systematic, community‐representative sample of 508 HIV‐affected households nested within 24 communities in KwaZulu‐Natal, South Africa. Two distinct dimensions of HAR stigma were measured: individual stigmatizing attitudes, and perceptions of community normative stigma. Findings suggest that individual‐level HAR stigma significantly predicts individual mental health (depression and anxiety) among HIV‐affected adults; and that community‐level HAR stigma significantly predicts both individual‐level mental health outcomes (anxiety) among HIV‐affected adults, and mental health outcomes (PTSD and externalizing behavior scores) among HIV‐affected children. Differentiated patterns of relationships were found using the two different stigma measures. These findings of unique relationships identified when utilizing two conceptually distinct stigma measures, at two levels of analysis (individual and community) suggest that HAR stigma in this context should be conceptualized as a multilevel, multidimensional construct. These findings have important implications both for mental health interventions and for interventions to reduce HAR stigma in this context. 相似文献

Higher trait self-control is related to less aggression, but the psychological processes underlying this association are largely unknown. This research tested the hypothesis that reduced anger rumination in high self-control individuals may partly account for this association. In seven cross-sectional, longitudinal and daily diary studies (total N = 2689) people high in trait self-control reported less aggression of different types and this relation was partially mediated by less rumination about anger-evoking events. An internal meta-analysis estimated this indirect effect to be of medium size. These findings suggest that a lower propensity to engage in anger rumination may be a crucial working process partly explaining how high trait self-control translates into less aggression. Overcoming anger rumination is a promising avenue to reduce aggression. 相似文献

In humans, infants respond positively to slow, gentle stroking—processed by C-tactile (CT) nerve fibers—by showing reductions in stress and increases in eye contact, smiling, and positive vocalizations. More frequent maternal touch is linked to greater activity and connectivity strength in social brain regions, and increases children’s attention to and learning of faces. It has been theorized that touch may prime children for social interactions and set them on a path towards healthy social cognitive development. However, less is known about the effects of touch on young infants’ psychological development, especially in the newborn period, a highly sensitive period of transition with rapid growth in sensory and social processing. It remains untested whether newborns can distinguish CT-targeted touch from other types of touch, or whether there are benefits of touch for newborns’ social, emotional, or cognitive development. In the present study, we experimentally investigated the acute effects of touch in newborn monkeys, a common model for human social development. Rhesus macaques (Macaca mulatta), like humans, are highly social, have complex mother-infant interactions with frequent body contact for the first weeks of life, making them an excellent model of infant sociality. Infant monkeys in the present study were reared in a neonatal nursery, enabling control over their early environment, including all caregiver interactions. One-week-old macaque infants (N = 27) participated in three 5-minute counter-balanced caregiver interactions, all with mutual gaze: stroking head and shoulders (CT-targeted touch), stroking palms of hands and soles of feet (Non-CT touch), or no stroking (No-touch). Immediately following the interaction, infants watched social and nonsocial videos and picture arrays including faces and objects, while we tracked their visual attention with remote eye tracking. We found that, during the caregiver interactions, infants behaved differently while being touched compared to the no-touch condition, irrespective of the body part touched. Most notably, in both touch conditions, infants exhibited fewer stress-related behaviors—self-scratching, locomotion, and contact time with a comfort object—compared to when they were not touched. Following CT-targeted touch, infants were faster to orient to the picture arrays compared to the other interaction conditions, suggesting CT-targeted touch may activate or prime infants’ attentional orienting system. In the No-touch condition infants attended longer to the nonsocial compared to the social video, possibly reflecting a baseline preference for nonsocial stimuli. In contrast, in both touch conditions, infants’ looked equally to the social and nonsocial videos, suggesting that touch may influence the types of visual stimuli that hold infants’ attention. Collectively, our results reveal that newborn macaques responded positively to touch, and touch appeared to influence some aspects of their subsequent attention, although we found limited evidence that these effects are mediated by CT fibers. These findings suggest that newborn touch may broadly support infants’ psychological development, and may have early evolutionary roots, shared across primates. This study illustrates the unique insight offered by nonhuman primates for exploring early infant social touch, revealing that touch may positively affect emotional and attentional development as early as the newborn period. 相似文献
