Responding to stimuli as same and different can be considered a critical component of a variety of language and academic repertoires. Whereas responding to “sameness” and generalized identity matching (i.e., coordination) have been studied extensively, there appears to be a significant gap in behavior analytic research and educational programs with regard to nonmatching relations or relations of difference. We review research on difference relations from a variety of domains, including comparative psychology, as well as experimental, and translational behavior analysis. We examine a range of studies, including research on the perception of difference and oddity responding, as well as investigations on establishing relational frames of distinction. We present suggestions for future research and describe potential methods for teaching skills related to relations of difference. 相似文献

Behavioural flexibility allows animals to adjust their behaviours according to changing environmental demands. Such flexibility is frequently assessed by the discrimination–reversal learning task. We examined grey squirrels’ behavioural flexibility, using a simultaneous colour discrimination–reversal learning task on a touch screen. Squirrels were trained to select their non-preferred colour in the discrimination phase, and their preferred colour was rewarded in a subsequent reversal phase. We used error rates to divide learning in each phase into three stages (perseveration, chance level and ‘learned’) and examined response inhibition and head-switching during each stage. We found consistent behavioural patterns were associated with each learning stage: in the perseveration stage, at the beginning of each training phase, squirrels showed comparable response latencies to correct and incorrect stimuli, along with a low level of head-switching. They quickly overcame perseveration, typically in one to three training blocks. In the chance-level stage, response latencies to both stimuli were low, but during initial discrimination squirrels showed more head-switches than in the previous stage. This suggests that squirrels were learning the current reward contingency by responding rapidly to a stimulus, but with increased attention to both stimuli. In the learned stage, response latencies to the correct stimulus and the number of head-switches were at their highest, whereas incorrect response latencies were at their lowest, and differed significantly from correct response latencies. These results suggest increased response inhibition and attention allowed the squirrels to minimise errors. They also suggest that errors in the ‘learned’ stage were related to impulsive emission of the pre-potent or previously learned responses. 相似文献

Recent studies have documented substantial variability among typical listeners in how gradiently they categorize speech sounds, and this variability in categorization gradience may link to how listeners weight different cues in the incoming signal. The present study tested the relationship between categorization gradience and cue weighting across two sets of English contrasts, each varying orthogonally in two acoustic dimensions. Participants performed a four-alternative forced-choice identification task in a visual world paradigm while their eye movements were monitored. We found that (a) greater categorization gradience derived from behavioral identification responses corresponds to larger secondary cue weights derived from eye movements; (b) the relationship between categorization gradience and secondary cue weighting is observed across cues and contrasts, suggesting that categorization gradience may be a consistent within-individual property in speech perception; and (c) listeners who showed greater categorization gradience tend to adopt a buffered processing strategy, especially when cues arrive asynchronously in time. 相似文献

ABSTRACTAlthough Asian Americans are diverse in many ways, such as language, culture, ethnicity, religion, generational status, and more, many share a common experience: that of having experienced war first hand or being progeny of war survivors. World War II, the Korean War, the Vietnam War, the Cambodian genocide, along with centuries of oppressive and authoritarian rule, have brought experiences of trauma, directly and historically, to the lives of many Asians. Subsequent experiences of migration and resettlement, as well as life in the United States as an ethnic minority, have also compounded the layers of oppression for many Asian Americans. Sexism in our cultures of origin, as well as sexism in the U.S., represents additional realities and traumas faced by Asian American women. In this article, we explore the experiences of war and subsequent traumas in the lives of Asian American women. We present a brief review of the current state of mental health as it relates to the experiences of war trauma, with the goal of providing a crucial contextual backdrop for our review of the best practices in mental health services to Asian American women. We review some of the best practices and conclude with a narrative reflection based on our own involvement in a small professional women’s group that yielded insights, discoveries, healing, and empowerment from the legacy of war trauma. 相似文献

Theorists have long argued that two forms of relative deprivation exist: individual‐based relative deprivation (IRD) whereby a person feels deprived relative to other individuals and group‐based relative deprivation (GRD) whereby a person feels his/her ingroup is deprived relative to other groups. Combinations of IRD and GRD are therefore assumed to produce four response profiles: (i) high on IRD and GRD (i.e. ‘doubly deprived’); (ii) high on IRD, low on GRD; (iii) low on IRD, high on GRD; or (iv) low on IRD and GRD. The existence of these profiles, however, has never been assessed. We address this oversight by using latent profile analysis to identify distinct response patterns to measures of IRD and GRD. Across two studies, we found no support for this typology, nor the oft‐assumed doubly deprived profile. Rather, response patterns showed moderate levels of IRD across discrete profiles accompanied by considerable variability in GRD. 相似文献

Although animal models based on amphetamine (AMPH) or phencyclidine (PCP) treatment have been used extensively to study the neurobiological and behavioral characteristics of schizophrenia, there are conflicting reports regarding their validity in modeling the negative symptoms and cognitive deficits of schizophrenia. The present study examined how acute AMPH or PCP treatment (Experiment 1) and withdrawal from repeated AMPH treatment (Experiment 2) or PCP treatment (Experiment 3) affects social behavior and social recognition memory in male Sprague‐Dawley rats. Each subject was tested on two consecutive days. On the first day, the rats were tested four times (5 min/each) at 10‐min intervals with the same partner rat (termed “AAAA” day). One day later, the rats were tested with the previous partner in the first three sessions and with a new partner rat in the final session (termed “AAAB” day). The results show that acute AMPH treatment (1.5 mg/kg, sc) significantly reduced the time spent on social interaction, but did not affect social recognition on the first day. Acute AMPH only disrupted social recognition on the second day of drug testing. In contrast, acute PCP treatment (2.0 mg/kg, sc) had no effect on time spent on social interaction, but did significantly disrupt social recognition on both days. Withdrawal from repeated AMPH (3.0 mg/kg/day for 7 days, ip) or PCP (5.0 mg/kg/twice daily for 7 days, ip) treatment did not affect social interaction or social recognition, indicating a lack of long‐term detrimental effect of repeated AMPH or PCP treatment. These results suggest that acute AMPH treatment at a low dose (1.5 mg/kg) may be useful in modeling social withdrawal symptoms of schizophrenia, whereas acute PCP treatment at a similar dose range (2.0 mg/kg) may be useful in modeling the social cognitive deficit of schizophrenia. 相似文献

Employing a survival analysis approach, this study synthesizes 3 aspects of gift literature and suggests their effects on the timing of dissolution for a romantic relationship. Products or services can be consumed for the purpose of enhancing self‐attractiveness (self‐gift), expressing love to partners (other‐gift), and announcing a relationship to the outer world (joint‐gift). Results indicate that the distribution of time until dissolution for young students’ romantic relationships is more likely to first fall and then rise. Gifts can delay the timing of dissolution, but not the probability of its final destination. For female students, self‐enhancing gifts are found to delay the timing; for male students, love‐expressive gifts speed up the timing; and for both male and female students, relationship‐announcing gifts delay the timing of dissolution. Consumers, thus, are advised to use gifts to make their relationships endure, but not to attempt to alter a poor relationship into a successful one. 相似文献

We examined investment in body image among 48 patients diagnosed with, or at risk for malignant melanoma (MM), as well as factors hypothesized as related to increased investment, such as gender, perceived stress, mood, fatigue, and personality characteristics. Investment in body image was evaluated using the Measure of Body Apperception [Carver, C. S., Pozo-Kaderman, C., Price, A. A., Noriega, V., Harris, S. D., Derhagopian, R. S., Robinson, D. S., & Moffat, F. L. Jr. (1998). Concern about aspects of body image and adjustment to early state breast cancer. Psychosomatic Medicine, 60, 168–174]. Results showed that women reported more concerns about physical appearance than men, and patients with MM exhibited more concerns about body integrity than at-risk patients. Concerns about body integrity were related to more compulsive personality characteristics, whereas concerns about appearance were associated with more histrionic personality characteristics. Body image investment was related to poorer adjustment as indicated by heightened symptoms of fatigue and stress. This study suggests that further research on investment in body image in this patient population is warranted. 相似文献

联合颜色−标签匹配任务和空间参照框架判断任务,考察自我优势效应对远近空间中空间参照框架表征的影响。颜色−标签匹配任务要求被试对颜色（黑色/白色叉子）与标签词（自我/他人）之间建立稳定的联结,被试随机分为自我联结组和他人联结组,两组被试均需在远近空间中完成空间参照表征任务。结果发现：（1）与他人联结组相比,自我联结组表现出显著的自我优势效应;（2）自我优势效应对空间参照表征的影响仅体现在近处空间且对自我中心表征任务的影响更大。研究表明,自我优势效应优先影响近处空间表征,表现出近处优先性。 相似文献
