Although rats are able to build complex spatial representations of their surroundings during exploration, the nature of the
encoded information is still a matter for debate. In particular, it is not well established if rats can process the topological
structure of the environment in such a way that they are aware of the connections existing between remote places. Here, rats
were first exposed for four 5-min trials to a complex environment divided into several sectors that were separated by doors
allowing either unrestricted or restricted access to other sectors. In the fifth test trial, we measured the behavior of the
animals while they explored the same environment in which, however, they faced changes that either altered or did not alter
the topological structure of the environment. In experiment 1, closing previously opened doors prevented the rat from having
direct access between corresponding sectors. In experiment 2, opening previously closed doors allowed direct access between
sectors that had not been directly accessible. In each experiment, control doors allowed us to discard the mere influence
of door manipulation. We compared the rats’ exploratory behavior in response to door manipulations that either strongly altered
or did not alter the ability to commute between sectors and found evidence that the animals displayed differential reactions
to the two types of door manipulations. This implies that during exploration rats build a precise map of the connectivity
of space that can be flexibly updated and used for efficient navigation. 相似文献

The current study provides naturalistic data documenting the pathways-to-care to vocational services for 155 veterans who were receiving some form of mental health care from the Veterans Health Administration and had a vocational need but were not currently enrolled in vocational services. Of the participants, 94.2% had recognized their vocational need, 80.6% reported that they or someone else had sought help to alleviate the need, and 77.4% had previously received some form of vocational services. The median length of the participants' vocational need was more than 4.2 years. Delays associated with recognition, help-seeking, and treatment entry all contributed to the overall delay in entering appropriate care. Filtering factors associated with quicker recognition, seeking help, and receiving services included diagnosis, level of disability, type of vocational need, and support from primary providers, family, and friends. The results provide information for designing interventions to improve service entry by adults with mental health problems and vocational needs. 相似文献

University of Colorado (CU) students were tested on memory for the “CU Fight Song” in order to examine serial position effects
in semantic memory while controlling for familiarity across positions. In Experiment 1, students reconstructed the order of the nine lines of the song. Students with previous exposure to the song performed better
and showed a more bowed serial position function than did students with no knowledge of the song. Experiment 2 added a task assessing memory of item information. One word was removed and replaced with a blank in each line, and an alternative
word was offered as an option, along with the correct word. Students selected the word that fit into each blank and then reconstructed
the order of the lines. There was a bow-shaped curve for order reconstruction, but not for item selection, which implies that
the serial position function in semantic memory stems from order, rather than item, information. 相似文献

This study examines factors that influence memory for details about people. In two experiments, subjects learned fictitious
details about familiar (friends, relatives) and/or unfamiliar individuals, and were tested both immediately and after a 1-week
delay. To control for a confounding between familiarity and genetic relatedness in Experiment 1, in Experiment 2 specific relationships (identical twin, first cousin, acquaintance) were assigned to unfamiliar individuals. Across experiments,
retention was enhanced for familiar compared to unfamiliar individuals, for friends/acquaintances compared to relatives, for
more closely than distantly related individuals, and for individuals of the opposite gender as the subject. 相似文献

Teacher expectancy effects, the class of phenomena in which teacher beliefs about students influence student outcomes, are widely believed to operate through recursive processes of teacher-student interaction. Recent work in “wise” interventions has shown profound and robust effects in educational domains, and has attributed these effects to similar recursive processes (Yeager and Walton 2011). In this paper, we lay a foundation for forging connections between what we know about expectancy effects and how we might envision applying that knowledge as a lever in intervention research. We review the evidence for the existence and significance of teacher expectancy effects, as well as their possible mediators, including perceptual biases, confirmation biases, stereotyping, and attributional biases. We also hypothesize that empathy could play a role in mediating a relationship between expectancies and attributions. Finally, we propose a research agenda focused on the transmission, mediation, and attributional effects of teacher expectancies. 相似文献

Identity fusion refers to a visceral sense of oneness with an ingroup. For fused individuals, group membership is not a means to an end (e.g., a positive social identity). Rather, membership is an all‐absorbing goal in itself; little other than the group matters. Group membership is also seen as enduring, sustained by chronically activated psychological structures as well as features of the context. Fellow group members are likewise seen as permanent members of the group, as they are members of the ingroup “family”. And just as family members are compelled to make extreme sacrifices for their family, so too are highly fused individuals – including even the ultimate sacrifice. These efforts to protect the ingroup can have negative consequences when, for example, people become strongly fused to groups that are devoted to extreme, anti‐social behaviors. In such instances, it may be prudent to encourage “defusion” from the group, but the emotional investment associated with fusion may thwart such efforts. We discuss the implications of these and related considerations. 相似文献

Whatever happened to Kony2012? Understanding a global Internet phenomenon as an emergent social identity 下载免费PDF全文

Kony2012 was a viral Internet video that attracted unprecedented online interest in promoting a campaign to arrest the leader of an African militant group. The current research considers the social psychological bases of social media‐based collective action. In three cross‐sectional surveys (N = 304) collected before, on, and after the key action date of 20 April 2012, we consider the nature (opinion based or global) and function (emergent or transforming) of social identity in modern forms of social action. Multigroup structural equation modelling showed that Kony2012 action was best captured by an emergent opinion‐based social identity. Moreover, the same factors that predicted Kony2012 action generally also predicted engagement in new repertoires of protest (involving the use of social media) and an observable traditional socio‐political action (signing a letter to a government minister). The results suggest that there is no sharp dividing line between traditional and new forms of collective action and that both may be understood as valid expressions of collective selfhood.
