The paper describes a treatment pilot for gambling and compulsive addiction within an NHS problem gambling clinic. The pilot study used a brief relational psychodynamic treatment protocol specifically designed to meet the needs of a group of patients who had not responded to CBT and who had other addictions or co‐morbidities. Seventy‐two (n = 72) patients were offered 12 sessions of therapy by four psychodynamic counsellors. Results were assessed using scores from a pre‐ and post‐treatment patient health questionnaire, the generalised anxiety disorder—7 (GAD‐7) and the Problem Gambling Severity Index (PGSI). Weekly feedback and supervision from counsellors and patients were used to assess the treatment model. The results highlighted that the psychodynamic addiction model was associated with reduced depression (Mean = 14.9; SD: 6.7), anxiety (Mean = 11.5; SD: 5.9), and gambling severity (p < .001), suggesting that a relational psychodynamic treatment is needed for complex patients with compulsive addiction, where CBT had not been successful. These results also highlight the importance of the therapeutic relationship as a critical factor in the treatment of patients with compulsive addiction problems.  相似文献

Most reports emphasize that tumors and their treatments affect sexual function. To date, no studies have focused on sexual functioning in patients with brain tumors. Our study’s objective is to describe the sexual sphere of patients with brain tumors and examine the possible differences between patients who reported sexual dysfunctions and those who did not with respect to their psychological and functional status. We tested 46 patients with brain tumors. We used an ad hoc questionnaire to assess patients’ subjective perception of their own sexual sphere. To assess patients’ psychological status, we used the following questionnaires: Hospital Anxiety and Depression Scale; Psychological Distress Inventory; EORTC QLQ-C30; EORTC QLQ-BN20. Fifty-eight percent of patients reported sexual disturbance. Our data showed that a lack of or decrease in sexual desire is the most common sexual problem reported by our patients (56%). Patients with sexual problems reported higher levels of anxiety and depression and a worse self-reported quality of life (QoL) than did those who did not perceive adverse changes in their sexual sphere. In addition, we found that patients with a better performance status (KPS) reported more changes in sexual behaviors than did those who had performance difficulties. Of the patients, 15.2% received information regarding possible changes in the sexual sphere by physicians. Additionally, 10.8 of 15.2% of the patients reported having explicitly requested information from physicians. The study demonstrated a relation between QoL and sexual function. Therefore, it would be important to encourage clinicians to ask questions regarding patients’ sexual issues, thus providing them with an opportunity to expose their difficulties and receive adequate support.  相似文献

Infants' perception of faces becomes attuned to the environment during the first year of life. However, the mechanisms that underpin perceptual narrowing for faces are only poorly understood. Considering the developmental similarities seen in perceptual narrowing for faces and speech and the role that statistical learning has been shown to play for speech, the current study examined whether and how learning from distributional information impacts face identity discrimination. We familiarized 6.5‐month‐old infants with exemplars of female faces taken from a morphed continuum going from one identity to another. Using event‐related brain potentials (ERPs), we show that only infants who were familiarized with a bimodal frequency distribution, but not infants familiarized with a unimodal frequency distribution, discriminated between identities. These results are the first to demonstrate the influence of probabilistic information on infants' face identity discrimination, suggesting that statistical learning contributes to perceptual attunement for both faces and language.  相似文献

In executing purposeful actions, adults select sufficient and necessary limbs. But infants often move goal‐irrelevant limbs, suggesting a developmental process of motor specialization. Two experiments with 9‐ and 12‐month‐olds revealed gradual decreases in extraneous movements in non‐acting limbs during unimanual actions. In Experiment 1, 9‐month‐olds produced more extraneous movements in the non‐acting hand/arm and feet/legs than 12‐month‐olds. In Experiment 2, analysis of the spatiotemporal dynamics of infants’ movements revealed developmental declines in the spatiotemporal coupling of movements between acting and non‐acting arms. We also showed that the degree of specialization in infants’ unimanual actions is associated with individual differences in motor experience and visual attention, indicating the experience‐dependent and broad functional nature of these developmental changes. Our study provides important new insights into motor development: as in cognitive domains, motor behaviours are initially broadly tuned to their goal, becoming progressively specialized during the first year of life.  相似文献

Can bilingual exposure impact children's neural circuitry for learning to read? To answer this question, we investigated the brain bases of morphological awareness, one of the key spoken language abilities for learning to read in English and Chinese. Bilingual Chinese‐English and monolingual English children (= 22, ages 7–12) completed morphological tasks that best characterize each of their languages: compound morphology in Chinese (e.g. basket + ball = basketball) and derivational morphology in English (e.g. re + do = redo). In contrast to monolinguals, bilinguals showed greater activation in the left middle temporal region, suggesting that bilingual exposure to Chinese impacts the functionality of brain regions supporting semantic abilities. Similar to monolinguals, bilinguals showed greater activation in the left inferior frontal region [BA 45] in English than Chinese, suggesting that young bilinguals form language‐specific neural representations. The findings offer new insights to inform bilingual and cross‐linguistic models of language and literacy acquisition.  相似文献

Past research has shown that young monolingual children exhibit language‐based social biases: they prefer native language to foreign language speakers. The current research investigated how children's language preferences are influenced by their own bilingualism and by a speaker's bilingualism. Monolingual and bilingual 4‐ to 6‐year‐olds heard pairs of adults (a monolingual and a bilingual, or two monolinguals) and chose the person with whom they wanted to be friends. Whether they were from a largely monolingual or a largely bilingual community, monolingual children preferred monolingual to bilingual speakers, and native language to foreign language speakers. In contrast, bilingual children showed similar affiliation with monolingual and bilingual speakers, as well as for monolingual speakers using their dominant versus non‐dominant language. Exploratory analyses showed that individual bilinguals displayed idiosyncratic patterns of preference. These results reveal that language‐based preferences emerge from a complex interaction of factors, including preference for in‐group members, avoidance of out‐group members, and characteristics of the child as they relate to the status of the languages within the community. Moreover, these results have implications for bilingual children's social acceptance by their peers.  相似文献

This conversation between the editors of Teaching Theology and Religion and Joanne Maguire Robinson continues an occasional series of interviews that has previously featured Jonathan Z. Smith, Stephen Prothero, Mary Pierce Brosmer, and Mary Elizabeth Mullino Moore. The exchange takes as its point of departure the teaching statement that Professor Robinson produced in support of her candidacy for the American Academy of Religion's Excellence in Teaching Award. Issues addressed include the impact of institutional context on one's teaching, teaching the humanities in universities that are ever more focused on job training, making the transition from a graduate program focused on research to teaching undergraduates who are unlikely to take even a second course in the study of religion, and ways in which women are challenged to navigate multiple responsibilities while striving to make their way in a male‐dominated academy.  相似文献

So-called “looks-at-nothing” have previously been used to show that recalling what also elicits the recall of where this was. Here, we present evidence from an eye-tracking study which shows that disrupting looks to “there” does not disrupt recalling what was there, nor do (anticipatory) looks to “there” facilitate recalling what was there. Therefore, our results suggest that recalling where does not recall what.  相似文献
