Processes of proactive interference were explored using the pigeon as a model system of memory. This study shows that proactive interference extends back in time at least 16 trials (and as many minutes), revealing a continuum of interference and providing a framework for studying memory. Pigeons were tested in a delayed same/different task containing trial-unique pictures. On interference trials, sample pictures from previous trials reappeared as test pictures on different trials. Proactive-interference functions showed greatest interference from the most recent trial and with the longer of two delays (10 s vs. 1 s). These interference functions are accounted for by a time-estimation model based on signal detection theory. The model predicts that accuracy at test is determined solely by the ratio of the elapsed time since the offset of the current-trial sample to the elapsed time since the offset of the interfering sample. Implications for comparing memory of different species and different types of memory (e.g., familiarity vs. recollection) are discussed.  相似文献

Abstract Using the general strain theory as a theoretical framework, the present longitudinal study investigated both face-to-face and cyber victimization in relation to cyber-displaced aggression. Longitudinal data were collected from 130 (70 women) young adults who completed measures assessing their victimization (face-to-face and cyber), cyber aggression, and both face-to-face and cyber-displaced aggression. Findings indicated that victimization in both social contexts (face-to-face and cyber) contributed to cyber-displaced aggression 6 months later (Time 2), after controlling for gender, cyber aggression, face-to-face displaced aggression, and cyber-displaced aggression at Time 1. A significant two-way interaction revealed that Time 1 cyber victimization was more strongly related to Time 2 cyber-displaced aggression when young adults had higher levels of face-to-face victimization at Time 1. Implications of these findings are discussed as well as a call for more research investigating displaced aggression in the cyber context.  相似文献

This study was the first to investigate the relationship between adult romantic attachment and marital satisfaction in a clinical sample of 172 distressed couples seeking therapy. Fifty-six therapy-seeking nondistressed couples were also assessed for comparison. Analyses of variance showed that attachment avoidance was a distinctive characteristic of distressed couples. Actor-partner analyses revealed that attachment avoidance (for men and women) and attachment anxiety (for women only) were predictive of marital dissatisfaction for distressed couples. Gender-stereotype discordant partner effects were also found. Results suggest that attachment orientations (especially avoidance) are relevant predictors of marital dissatisfaction in distressed couples seeking therapy, and that couple therapists can gain important information by assessing partners’ attachment orientations.  相似文献

Using the film The Cook, the Thief His Wife and her Lover (from which this paper's title is borrowed) as a powerful illustration, the paper examines some of the unconscious processes which form part of everyday life for nurses working in the community, particularly on the wards of our hospitals. It is an attempt to describe some of these processes and to understand the conditions that promote them. With acknowledgements to the pioneers in this sort of work, such as Main, Menzies-Lyth, Trist, Bamforth and Jaques, the paper looks at the ethology of institutions and at activity that takes place on the boundaries between self and other, between the inner world and external reality, and between various levels in the hierarchy.

The paper identifies some of the ‘routines’ which grew up in nursing (and those which have replaced them), the unconscious purpose of which is to safeguard the emotional and psychological integrity of the nurse, through creating a distance between herself and her patients. The paper argues against removing these necessary defences until more helpful alternatives are in place. To fulfil this aim, it recommends that clinical supervision and support seminars should become a regular part of all nurse-training programmes, and should continue throughout the professional life of the nurse.  相似文献

This study evaluated the efficacy of the Mind Reading interactive computer software to remediate emotion recognition deficits in children with autism spectrum disorders (ASD). Six unmedicated children with ASD and 11 unmedicated non-clinical control subjects participated in the study. The clinical sample used the software for five sessions. The control sample was evaluated only on pre- and post-test performance to assess practice effects. Results showed that participants with ASD scored significantly higher on the posttest than on the pretest. As level of emotion difficulty increased, mean scores on the pretest decreased, indicating that difficulty level had a valid effect. The Mind Reading computer software appears to significantly improve the emotion recognition abilities in children with ASD.  相似文献

The conflict adaptation effect, a reduced interference effect upon the detection of a conflict signal (e.g., following an incongruent trial), has been interpreted as evidence for active regulation of top-down cognitive control. We hypothesized that the extent of conflict adaptation should be related to individuals' working memory capacity (WMC), which has been repeatedly demonstrated to reflect the level of cognitive control. Using the Simon task, in Experiment 1, we quantified the conflict adaptation ratio (CAR) transiently as the ratio of the conflict effect following an incongruent trial to the conflict effect following a congruent trial, controlling for the reaction time that often correlates with WMC. We observed that the CAR varied from highly negative with low WMC scores to near-zero with high WMC scores. This result suggests that high WMC individuals, when detecting conflict, adjust the level of cognitive control optimally so that their performance is less susceptible to the presence of a distractor. In Experiment 2, we quantified the CAR in a sustained manner as the ratio of the conflict effect from predominantly incongruent blocks to the conflict effect from predominantly congruent blocks. Again, the CAR varied from negative to zero as WMC increased. These results suggest that WMC may reflect, in addition to the ability to maintain a level of control, the ability to adjust the level of control appropriately to the contextual demands.  相似文献

Learning and memory abilities tend to decline as people age. The current study examines the question of whether a learning situation that emphasises collaborative social interaction might help older persons overcome age-related learning and memory changes and thus perform similarly to younger persons. Younger and Older participants (n = 34 in each group) completed the Barrier Task (BT), a game-like social interaction where partners work together to develop labels for a set of abstract tangrams. Participants were also administered standard clinical neuropsychological measures of memory, on which the Older group showed expected inferiority to the Younger group. On the BT, the Older group performed less well than the Younger group early on, but as the task progressed, the performance of the Older group caught up and became statistically indistinguishable from that of the Younger group. These results can be taken to suggest that a learning milieu characterised by collaborative social interaction can attenuate some of the typical memory disadvantages associated with being older.  相似文献

Recognizing the relatively low rate at which sexual assault survivors seek services, researchers in the last decade have turned their attention to better understanding survivors’ experiences with victim services. Surprisingly, limited research has directly asked sexual assault survivors for recommendations on how to improve victim services, including both criminal justice and community-based services. The current study builds on the existing literature to gather input from women survivors that can translate into ways to improve victim services. As part of a larger longitudinal study, the current investigation asked 224 ethnically diverse adult (aged 18–62) women survivors of recent sexual assault to provide recommendations for how victim services can best serve survivors of sexual assault at multiple time points. Nearly all women in the study (91%) offered specific recommendations on how to improve victim services. Recommendations included ensuring availability of a female provider, improving communication with survivors as well as within and between service providers, helping survivors obtain resources, believing and not blaming survivors, demonstrating greater understanding of trauma-related responses and approaching survivors with greater compassion, and implementing better training on effectively working with survivors. Implications for victim service provision are discussed.  相似文献

Transitive inference underpins many human reasoning competencies. The dominant task (the “extensive training paradigm”) employs many items and large amounts of training, instilling an ordered series in the reasoner's mind. But findings from an alternative “three-term paradigm” suggest transitivity is not present until 7 + years. Interestingly, a second alternative paradigm (the “spatial task”), using simultaneously displayed height relationships to form premise pairs, can uphold the 4-year estimate. However, this paradigm risks cueing children and hence is problematic. We investigated whether a height-task variant might correspond to a more ecologically valid three-term task. A total of 222 4–6-year-olds either completed a modified height task, including an increased familiarisation phase, or a computer-animated task about cartoon characters running a race in pairs. Findings confirmed that both tasks were functionally identical. Crucially, 4-year-olds were at chance on both, whereas 6-year-olds performed competently. These findings contrast with estimates from all three paradigms considered. A theoretical evaluation of our tasks and procedures against previous ones, leads us to two conclusions. First, our estimate slightly amends the 7-year estimate offered by the three-term paradigm, with the difference explained in terms of its greater relevance to child experiences. Second, our estimate can coexist alongside the 4-year estimate from the extensive training paradigm. This is because, applying a recently developed “dual-process” conception of reasoning, anticipates that extensive training benefits a species-general associative system, while the spatial paradigm and three-term paradigm can potentially index a genuinely deductive system, which has always been the target of transitive research.  相似文献
