Artificial Nature

To study the evolution of humans’ cooperative nature, researchers have recently sought comparisons with other species. Studies investigating corvids, for example, showed that carrion crows and azure-winged magpies delivered food to group members when tested in naturalistic or simple experimental paradigms. Here, we investigated whether we could replicate these positive findings when testing the same two species in a token transfer paradigm. After training the birds to exchange tokens with an experimenter for food rewards, we tested whether they would also transfer tokens to other birds, when they did not have the opportunity to exchange the tokens themselves. To control for the effects of motivation, and of social or stimulus enhancement, we tested each individual in three additional control conditions. We witnessed very few attempts and/or successful token transfers, and those few instances did not occur more frequently in the test condition than in the controls, which would suggest that the birds lack prosocial tendencies. Alternatively, we propose that this absence of prosociality may stem from the artificial nature and cognitive complexity of the token transfer task. Consequently, our findings highlight the strong impact of methodology on animals’ capability to exhibit prosocial tendencies and stress the importance of comparing multiple experimental paradigms.

Social Learning Strategies

Social learning theories predict biased transmission dictating what and whom is copied. We presented a novel tool-use task to six groups of captive chimpanzees (Pan troglodytes) to investigate a model proficiency bias. The study included six groups totalling 54 chimpanzees (24 males) housed in six social groups at the KCCMR, University of Texas, U.S.A. Subjects were aged 12- to 43-years-old (M = 24.5 years, SD = 7). In each of four groups (N = 33, Males = 18), two models were trained to use one of two visually and functionally different ‘hook’ and ‘spoon’ tools to obtain baskets containing food that were otherwise out-of-reach. Once trained, the models demonstrated their tool-use in the presence of the group. The two models differed in their novel-task-solving proficiency as ascertained by prior interactions with novel tasks (also observed by group members) and caregiver ratings of each chimpanzee’s general proficiency. Two groups of ‘control’ chimpanzees (N = 21) had no prior information regarding the task and saw no conspecific demonstrations. Within the experimental groups, significantly more chimpanzees touched the tool used by the ‘high proficiency’ model than the one used by the ‘low proficiency’ model (p < 0.001), demonstrating some degree of model-based social learning bias. The tool used in observing chimpanzees’ first attempts and first successes, however, did not differ as a function of which model used the tool. This was likely because the task could be easily learned asocially. We propose that the chimpanzees’ tool-use behaviour was guided by biased stimulus enhancement alongside asocial learning. As with humans, chimpanzees demonstrate an ability to discern the most proficient model but also show the flexibility to asocially acquire multiple successful methods. Thus, chimpanzees and humans both demonstrate adaptive social learning strategies dictating when and whom they copy.

Flexible targeted helping is considered an advanced form of prosocial behavior in hominoids, as it requires the actor to assess different situations that a conspecific may be in, and to subsequently flexibly satisfy different needs of that partner depending on the nature of those situations. So far, apart from humans such behaviour has only been experimentally shown in chimpanzees and in Eurasian jays. Recent studies highlight the prosocial tendencies of several bird species, yet flexible targeted helping remained untested, largely due to methodological issues as such tasks are generally designed around tool-use, and very few bird species are capable of tool-use. Here, we tested Goffin’s cockatoos, which proved to be skilled tool innovators in captivity, in a tool transfer task in which an actor had access to four different objects/tools and a partner to one of two different apparatuses that each required one of these tools to retrieve a reward. As expected from this species, we recorded playful object transfers across all conditions. Yet, importantly and similar to apes, three out of eight birds transferred the correct tool more often in the test condition than in a condition that also featured an apparatus but no partner. Furthermore, one of these birds transferred that correct tool first more often before transferring any other object in the test condition than in the no-partner condition, while the other two cockatoos were marginally non-significantly more likely to do so. Additionally, there was no difference in the likelihood of the correct tool being transferred first for either of the two apparatuses, suggesting that these birds flexibly adjusted what to transfer based on their partner´s need. Future studies should focus on explanations for the intra-specific variation of this behaviour, and should test other parrots and other large-brained birds to see how this can be generalized across the class and to investigate the evolutionary history of this trait.

AbstractWhitehouse adapts insights from evolutionary anthropology to interpret extreme self-sacrifice through the concept of identity fusion. The model neglects the role of normative systems in shaping behaviors, especially in relation to violent extremism. In peaceful groups, increasing fusion will actually decrease extremism. Groups collectively appraise threats and opportunities, actively debate action options, and rarely choose violence toward self or others.

Purpose It is known that people who stutter (PWS) benefit from self-help experiences, such as attending support groups or conferences. However, limited research has been done to explore the listening of stuttering-related podcasts as a form of self-help for PWS. This study seeks to understand the reasons why PWS listen to stuttering-related podcasts and provide descriptions of their listening experiences. Method Thirty-three PWS who have listened to stuttering-related podcasts were recruited to participate in an online survey that included multiple-choice and open-ended questions. Responses were analyzed and grouped into descriptive themes. Results Participants reported listening to stuttering-related podcasts as a way to gain information and perspective. They also reported experiences that fit themes of empowerment and camaraderie, as a result of listening. Conclusions Stuttering-related podcasts seem to be a positive self-help tool for PWS. Stuttering support group leaders and/or speech-language pathologists may consider introducing their group members or clients who stutter to this type of audio-based self-help experience.

Yzerbyt, Rogier and Fiske (1998) argued that perceivers confronted with a group high in entitativity (i.e., a group perceived as an entity, a tight-knit group) more readily call upon an underlying essence to explain people's behavior than perceivers confronted with an aggregate. Their study showed that group entitativity promoted dispositional attributions for the behavior of group members. Moreover, stereotypes emerged when people faced entitative groups. In this study, we replicate and extend these results by providing further evidence that the process of social attribution is responsible for the emergence of stereotypes. We use the attitude attribution paradigm ( Jones & Harris, 1967 ) and show that the correspondence bias is stronger for an entitative group target than for an aggregate. Besides, several dependent measures indicate that the target's group membership stands as a plausible causal factor to account for members' behavior, a process we call Social Attribution. Implications for current theories of stereotyping are discussed.

Conflict Detection And Resolution

Errors can play a major role for optimizing subsequent performance: Response conflict associated with (near) errors signals the need to recruit additional control resources to minimize future conflict. However, so far it remains open whether children and older adults also adjust their performance as a function of preceding response conflict. To examine the life span development of conflict detection and resolution, response conflict was elicited during a task-switching paradigm. Electrophysiological correlates of conflict detection for correct and incorrect responses and behavioral indices of post-error adjustments were assessed while participants in four age groups were asked to focus on either speed or accuracy. Despite difficulties in resolving response conflict, the ability to detect response conflict as indexed by the Ne/ERN component was expected to mature early and be preserved in older adults. As predicted, reliable Ne/ERN peaks were detected across age groups. However, only for adults Ne/ERN amplitudes associated with errors were larger compared to Nc/CRN amplitudes for correct trials under accuracy instructions, suggesting an ongoing maturation in the ability to differentiate levels of response conflict. Behavioral interference costs were considerable in both children and older adults. Performance for children and older adults deteriorated rather than improved following errors, in line with intact conflict detection, but impaired conflict resolution. Thus, participants in all age groups were able to detect response conflict, but only young adults successfully avoided subsequent conflict by up-regulating control.

Individual Achievement

Network autocorrelation occurs when individuals receive assistance from others which regulates their own behavior, and it can be used to explain how group members may improve their task performance. This study explored how network autocorrelation, via informal communication within a virtual group, affected an individual’s task achievement in the online game World of Warcraft. Informal interactions between guild members during a 4-year period were collected and analyzed to assess how informal interactions with other group members affected an individual’s in-game achievement. Findings indicate informal communication from other group members (specifically the experience and helpfulness of the other members) positively predict an individual’s task performance, while tenure with the group negatively predict individual achievement. Findings are discussed with respect to network analysis and influence in online groups.
