Fetal and infant rats can learn to avoid odors paired with illness before development of brain areas supporting this learning in adults, suggesting an alternate learning circuit. Here we begin to document the transition from the infant to adult neural circuit underlying odor-malaise avoidance learning using LiCl (0.3 M; 1% of body weight, ip) and a 30-min peppermint-odor exposure. Conditioning groups included: Paired odor-LiCl, Paired odor-LiCl-Nursing, LiCl, and odor-saline. Results showed that Paired LiCl-odor conditioning induced a learned odor aversion in postnatal day (PN) 7, 12, and 23 pups. Odor-LiCl Paired Nursing induced a learned odor preference in PN7 and PN12 pups but blocked learning in PN23 pups. 14C 2-deoxyglucose (2-DG) autoradiography indicated enhanced olfactory bulb activity in PN7 and PN12 pups with odor preference and avoidance learning. The odor aversion in weanling aged (PN23) pups resulted in enhanced amygdala activity in Paired odor-LiCl pups, but not if they were nursing. Thus, the neural circuit supporting malaise-induced aversions changes over development, indicating that similar infant and adult-learned behaviors may have distinct neural circuits. 相似文献

Fat talk and self-presentation of body image: Is there a social norm for women to self-degrade? 总被引:2,自引:2,他引:0
The current investigations build upon previous ethnographic research, which identified a social norm for adolescent females to engage in “fat talk” (informal dialogue during which individuals express body dissatisfaction). In Study 1, participants were shown a vignette involving women engaging in fat talk dialogue and were subsequently asked to chose one of three self-presentational responses for a target female: (1) self-accepting of her body, (2) providing no information, or (3) self-degrading about her body. Male and female participants believed the target would be most likely to self-degrade, and that this would lead women to like her, while the self-accepting response would lead men to like her most. Study 2 used the same vignette but participants were asked to respond in an open-ended fashion. Participants again expected the target female to self-degrade. The present findings suggest college students perceive fat talk self-degradation of body image as normative. 相似文献

This study investigates sex and race differences in normative beliefs about the acceptability of aggression across dimensions of severity of provocation (weak versus strong) and sex of provoker (male versus female). Students in the sample of 311 included those required to attend three Department of Youth Services schools after placement by the juvenile court system from across the state of Alabama (N=392). Results show that males were significantly more likely than females to approve of retaliation to weak provocation and against females. There were no significant differences between males and females for retaliation with strong provocation and against males. Results also show the Black group was significantly more likely than the White group to approve of retaliation to weak provocation, strong provocation, and against females. 相似文献

In order to advance the detection and prevention of suicide, recent research has focused on predictors of suicidal ideation and behavior such as negative cognitive styles, dysfunctional attitudes, hopelessness, and rumination. In this study the relationships among these risk factors in the context of the Attention Mediated Hopelessness (AMH) theory of depression are examined. One hundred and twenty-seven undergraduates in the Cognitive Vulnerability to Depression (CVD) project were followed for 2.5 years. The CVD project followed initially nondepressed freshmen, at either high or low cognitive risk for depression, in order to predict onsets and recurrences of depressive disorders. The presence and duration of suicidal ideation were predicted prospectively by rumination and hopelessness, and hopelessness partially mediated the relationship between rumination and ideation and fully mediated the association between rumination and duration of suicidality. Further, rumination mediated the relationship between cognitive vulnerability and suicidal ideation. 相似文献

Retention interval and rehearsal effects on flashbulb and event memory for 11th September 2001 (9/11) were examined. In Experiment 1, college students were assessed three times (Groups 1 and 2) or once (Group 3) over 11 weeks. In Experiment 2, three new groups assessed initially at 23 weeks (Group 4), 1 year (Group 5), or 2 years (Group 6) were compared at 1 year and at 2 years with subsamples of those assessed previously. No effects of retention interval length or rehearsal were found for flashbulb memory, which contained details at each assessment. Event memory, but not consistency, was detrimentally affected by long retention intervals, but improved with rehearsal. Recall was higher for the reception event than for the main events. Also, consistency from 1 day to 11 weeks, but not 1 year to 2 years, was higher for flashbulb memory than for event memory. Event recall was enhanced when respondents conceived of their memory as vivid, frozen, and encompassing a longer period of time. Positive correlations were found for event memory with confidence in accuracy and with rehearsal through discussion at 2 years. 相似文献

This research examined whether the impact of overheard rumors on children’s memory for their experiences varies as a function of social processes. The results of two experiments revealed that the very same errant rumor had different consequences for children’s recollections depending on the degree and type of social interactions they had with peers after exposure to the rumor. In both experiments, 3- to 5-year-olds overheard a false rumor about a recently experienced event and then were interviewed about the event 1 week later. In Experiment 1, children were more likely to report experiencing rumored-but-nonoccurring information if they were allowed to interact naturally with peers following exposure to the rumor than if they were prevented from peer exchange. In Experiment 2, exposure to the rumor induced greater memory contamination if it was planted among familiar peers than if it was encountered among strangers. 相似文献

Using a national dataset of 820 women who had called the police for an incident of intimate partner violence, this study explored the relationship between several components of socioeconomic status (education, income, and employment), race, and the nature of interactions with police. Over and above the effects of control variables (the presence of an advocate on the scene, the severity of violence in the relationship, and prior calls to police), victims with higher education reported less positive interactions, less control during the interactions, and lower effectiveness of police. Race did not moderate these relationships, and the other components of socioeconomic status were not significantly related to any of the outcomes. Exploratory tests of mediation found that the relationship between education and the quality of interactions with police was explained by the fact that more educated victims felt they had less control in these incidents and were less likely to see the offender arrested. Results also provide evidence for the positive impact of advocates on interactions with police. Implications for research and policy are discussed. 相似文献

The fallibility of memory in judicial processes: Lessons from the past and their modern consequences
The capability of adult and child witnesses to accurately recollect events from the past and provide reliable testimony has been hotly debated for more than 100 years. Prominent legal cases of the 1980s and 1990s sparked lengthy debates and important research questions surrounding the fallibility and general reliability of memory. But what lessons have we learned, some 35 years later, about the role of memory in the judicial system? In this review, we focus on what we now know about the consequences of the fallibility of memory for legal proceedings. We present a brief historical overview of false memories that focuses on three critical forensic areas that changed memory research: children as eyewitnesses, historic sexual abuse and eyewitness (mis)identification. We revisit some of the prominent trials of the 1980s and 1990s to not only consider the role false memories have played in judicial decisions, but also to see how this has helped us understand memory today. Finally, we consider the way in which the research on memory (true and false) has been successfully integrated into some courtroom procedures. 相似文献

In my response to the commentaries by Anthony Bass, Irwin Hirsch, and Margaret Crastnopol, I focus on conscious and unconscious factors that open or close potential space across relational realms, including that of analyst and patient, parent and child. I then extend these notions to the supervisory relationship. I describe how these issues affected the writing process for me, and explore the impact that writing has had on the ongoing treatment with my patient. I consider too the ways in which shame travels intersubjectively, shutting down transitional space and interfering with aliveness, authenticity, and creativity. 相似文献
