Proactive interference occurs when information from the past disrupts current processing and is a major source of confusion and errors in short-term memory (STM; Wickens, Born, & Allen, Journal of Verbal Learning and Verbal Behavior, 2:440–445, 1963). The present investigation examines potential boundary conditions for interference, testing the hypothesis that potential competitors must be similar along task-relevant dimensions to influence proactive interference effects. We manipulated both the type of task being completed (Experiments 1, 2, and 3) and dimensions of similarity irrelevant to the current task (Experiments 4 and 5) to determine how the recent presentation of a probe item would affect the speed with which participants could reject that item. Experiments 1, 2, and 3 contrasted STM judgments, which require temporal information, with semantic and perceptual judgments, for which temporal information is irrelevant. In Experiments 4 and 5, task-irrelevant information (perceptual similarity) was manipulated within the recent probes task. We found that interference from past items affected STM task performance but did not affect performance in semantic or perceptual judgment tasks. Conversely, similarity along a nominally irrelevant perceptual dimension did not affect the magnitude of interference in STM tasks. Results are consistent with the view that items in STM are represented by noisy codes consisting of multiple dimensions and that interference occurs when items are similar to each other and, thus, compete along the dimensions relevant to target selection. 相似文献
This literature review sought to examine the extant literature on the relationship between emergency response services (ERS) personnel and suicide in Canada. The purpose was to determine what research has been conducted on suicide and suicide ideation among ERS, to contribute to knowledge in the area, and also to identify potential research gaps. Through a search of multiple databases (PubMed, Web of Science, Medline, Psyc Articles, Psyc Info, Science Direct, CINAHL) and additional hand searching, 40 articles were identified to meet search criteria and provide relevant information on this topic. The articles revealed that research has primarily focused on the traumatic stress and critical incidents encountered by emergency responders, while little research has been conducted specifically on suicide within these professions. The minimal research that has focused on suicide generally discusses ERS encounters with suicide victims and patients, rather than suicide in the context of their personal mental health. The limited research that does discuss ERS suicide is largely restricted to law enforcement and military personnel. Finally, the literature search identified a particular lack of research relevant to the Canadian context. A research agenda is recommended to further investigate suicide among ERS within Canada, and the impact these suicides have on colleagues, families and friends. 相似文献
Background: Hysterectomy and mastectomy surgery for gender affirmation have traditionally been performed as separate surgeries. Our institution offers these surgeries as a single combined procedure, typically with same-day discharge. Decreasing the number of times patients need to have surgery may reduce barriers to care by limiting surgical and hospital stay events. Our primary objective was to describe the perioperative experience of transgender patients who underwent combined hysterectomy and mastectomy surgery.
Methods: This retrospective case series assessed patients who underwent combined hysterectomy and mastectomy surgery between 2013 and 2015 in an integrated health care setting in the United States. Chart reviews were performed for outcomes of interest, which included operative and postoperative complications.
Results: We identified 25 patients who underwent a combined hysterectomy and mastectomy for the indication of gender transition. Preoperative patient characteristics included a median age of 31, with a median BMI of 25. Ninety-two percent of the patients were on testosterone therapy at the time of surgery. A total of 76% and 24% of patients had laparoscopic and vaginal hysterectomies, respectively. Intraoperatively, the average blood loss was 104 mL, and there were no complications. Eighty percent of patients were discharged on the same day. Postoperatively, 92% of patients experienced no major complications. One patient received a uterine artery embolization and blood transfusion for postoperative intraabdominal bleeding, and one patient presented 9 weeks after surgery with partial vaginal cuff dehiscence requiring a cuff revision. There were no re-admissions within six months of surgery. There were no major mastectomy-related complications.
Conclusions: Combined surgeries are feasible and reduce the number of surgical events and hospital stays. There were no complications that could be attributed to undergoing two procedures as a single incident. 相似文献
Background: Transgender and gender-diverse (TGD) individuals face stigma in the general public and in the workplace. Research has suggested that TGD individuals may demonstrate unique coping strategies in the workplace in order to manage transphobia in that setting; however, further research is needed to identify the specific strategies that transgender individuals use to deal with transphobia at work.
Method: The present qualitative study utilized the grounded theory methodology to identify the specific coping strategies utilized to deal with transphobia at work. Participants included 45 TGD participants from the northeastern United States.
Results: The results of the study include the identification of eight coping-strategy themes including gender-presentation strategies, gender detachment, relationship navigating, resource utilization, job-performance strategies, maladaptive coping strategies, structural strategies, and power-acquisition strategies.
Conclusions: Implications of the present study suggest the resilience and diverse coping strategies that mental health providers can help TGD workers draw from in dealing with transphobia at work. In addition, there is a need for greater remediation and prevention of employment-related transphobia, including leadership within employment settings, greater legal protections, and enforcement of these laws in the United States. 相似文献
The present study examined whether beliefs about the importance of thoughts (i.e., thought–action fusion; TAF) are related to the target subject of the negative thought. One hundred and seven undergraduate students were randomly assigned to imagine either a beloved relative or a stranger being diagnosed with cancer and provided in vivo ratings of anxiety, likelihood, moral wrongness, urge to neutralize, and how upsetting the event would be if it occurred. Results indicated that thinking of a relative being diagnosed with cancer provoked more distress, urges to neutralize, and higher estimates of likelihood, as well greater use of mental neutralizing behaviors, compared to thinking of a stranger. Contrary to our prediction, the groups did not differ in their ratings of the moral wrongness. These findings broadly support the assertion that the more personally significant a negative intrusive thought, the more it will provoke distress and urges to neutralize. Results are discussed in terms of the cognitive model of obsessions and clinical implications are addressed. 相似文献
Chimpanzees (Pan troglodytes) have been known to exhibit rudimentary abilities in analogical reasoning (Flemming, Beran, Thompson, Kleider, & Washburn, 2008; Gillian, Premack, & Woodruff, 1981; Haun & Call, 2009; Thompson & Oden, 2000; Thompson, Oden, & Boysen, 1997). With a wide array of individual differences, little can be concluded about the species' capacity for analogies, much less their strategies employed for solving such problems. In this study, we examined analogical strategies in 3 chimpanzees using a 3-dimensional search task (e.g., Kennedy & Fragaszy, 2008). Food items were hidden under 1 of 2 or 3 plastic cups of varying sizes. Subsequently, chimpanzees searched for food under the cup of the same relative size in their own set of cups--reasoning by analogy. Two chimpanzees initially appeared to fail the first relational phase of the task. Meta-analyses revealed, however, that they were instead using a secondary strategy not rewarded by the contingencies of the task--choosing on the basis of the same relative position in the sample. Although this was not the intended strategy of the task, it was nonetheless analogical. In subsequent phases of the task, chimpanzees eventually learned to shift their analogical reasoning strategy to match the reward contingencies of the task and successfully choose on the basis of relative size. This evidence not only provides support for the analogical ape hypothesis (Thompson & Oden, 2000), but also exemplifies how foundational conceptually mediated analogical behavior may be for the chimpanzee. 相似文献
In the current study, we examined the effects of women's suppressing negative gender stereotypes while interacting with a male confederate. Compared with control participants, those who suppressed negative thoughts about women's ability experienced less self-confidence, lower self-esteem, and were more nonverbally submissive during the interaction, particularly if they were high in stigma consciousness (Pinel, 1999). These findings illustrate the negative intra- and interpersonal consequences of stigma suppression. 相似文献
Interference is a major source of short-term errors of memory. The present investigation explores the relationship between
two important forms of interference: proactive interference (PI), induced by the need to reject recently studied items no
longer relevant to task performance, and semantic interference (SI), induced by the need to reject lures sharing a meaningful
relationship with current memoranda. We explore the possibility that shared cognitive control processes are recruited to resolve
both forms of interference. In Experiment 1, we find that the requirement to engage in articulatory suppression during the retention interval of tasks that induce either
PI or SI increases both forms of interference similarly and selectively. In Experiment 2, we develop a task to examine PI and SI within the same experimental context. The results show interactive effects between
factors that lead to the two forms of interference. Taken together, these findings support contextual-cuing models of short-term
remembering (Nairne, Annual Review of Psychology, 53, 53–81 2002), where the context in which retrieval occurs can influence susceptibility to interference. Lastly, we discuss several theoretical
hypotheses concerning the cognitive control processes that are recruited to resolve SI and PI in short-term remembering. 相似文献
