Four experiments were conducted to determine the effects of bilateral damage to the hippocampus and area parahippocampalis (Hp-APH) on visual memory in pigeons using the delayed matching-to-sample (DMS) procedure. In Experiment 1, we generated visual retention gradients with delays of 0, 1.5, 3, 6, and 12 sec both preoperatively and postoperatively in three pigeons with considerable preoperative visual DMS experience. Bilateral Hp-APH lesions had no effect whatsoever on visual retention. In Experiment 2, we examined the effects of Hp-APH lesions on both the acquisition of a visual DMS task with a 0-sec delay, and the subsequent retention performance with delays of 0, 3, 6, 12, and 24 sec. There was no difference between unoperated control pigeons and Hp-APH pigeons either in terms of the number of sessions required to learn the visual DMS task or in terms of their subsequent visual retention performance levels. In Experiments 3 and 4, we examined whether Hp-APH pigeons might be more sensitive than control pigeons to the effects of proactive interference (by reducing the duration of the intertrial interval) and retroactive interference (by introducing delay-interval illumination). Although reducing the duration of the intertrial interval and increasing the level of delay-interval illumination both resulted in lower performance levels on the visual DMS task, there was no indication that the Hp-APH pigeons were any more affected by the changes in interference levels than were unoperated control pigeons. These findings support the view that the Hp-APH in pigeons plays little role in the processing and retention of purely visual information. 相似文献

ABSTRACT This study examined whether the status (central or peripheral position) of individuals in a friendship network and the quality of a friendship network represent key mechanisms in determining how emotional intelligence is associated with subjective well-being. Using data collected from 217 Chinese senior undergraduates, we found that the interaction of the quality of a friendship network and a peripheral position in a friendship network mediated relations of emotional intelligence with subjective well-being. Although a central position in a friendship network did not interact with the quality of a friendship network, it did mediate the relations of emotional intelligence with subjective well-being on its own. The findings expand the growing body of research findings on the association between emotional intelligence and subjective well-being by investigating the role of friendship networks and highlight the importance of a network perspective in understanding the association. 相似文献

ABSTRACT?Background: Little research has compared the mental health and victimization experiences of non-binary youth depending on their sex assigned at birth (SAAB), or compared these two groups with binary transgender youth.Aims: To compare mental health, self-harm and suicidality, substance use and victimization experiences between non-binary and binary transgender young adults, both male assigned at birth (MAAB) and female assigned at birth (FAAB).Methods: Online survey data from 677 participants from the “Youth Chances” community study of 16 to 25 year olds in the United Kingdom was analyzed, comparing across binary participants (transgender females (n = 105) and transgender males (n = 210)) and non-binary participants (MAAB (n = 93) and FAAB (n = 269)).Results: Female SAAB participants (binary and non-binary) were more likely to report a current mental health condition and history of self-harm than male SAAB participants (binary and non-binary). Similarly, female SAAB participants (binary and non-binary) were more likely to report childhood sexual abuse than male SAAB participants (binary and non-binary); the reverse pattern was found for lifetime physical assault relating to being LGBTQ. Non-binary MAAB participants were less likely than the other groups to report past suicide attempts and previous help-seeking for depression/anxiety. Binary participants reported lower life satisfaction than non-binary participants. For all four groups, mental health problems, self-harm, suicidality, alcohol use and victimization experiences were generally higher than that of youth in general population studies.Conclusions: These findings highlight the importance of considering both non-binary versus binary gender identity and SAAB in relation to mental health problems, self-harm, suicidality and substance use in transgender youth. The roles of sexual abuse, other abuse and discrimination in contributing to increased rates of mental illness and self-harm in non-binary and binary transgender individuals, particularly those who were assigned female at birth, relative to those assigned male, require investigation. 相似文献
