Reinforcement learning (RL) models of decision‐making cannot account for human decisions in the absence of prior reward or punishment. We propose a mechanism for choosing among available options based on goal‐option association strengths, where association strengths between objects represent previously experienced object proximity. The proposed mechanism, Goal‐Proximity Decision‐making (GPD), is implemented within the ACT‐R cognitive framework. GPD is found to be more efficient than RL in three maze‐navigation simulations. GPD advantages over RL seem to grow as task difficulty is increased. An experiment is presented where participants are asked to make choices in the absence of prior reward. GPD captures human performance in this experiment better than RL.  相似文献

Previous studies suggest in line with dual process models that interoceptive skills affect controlled decisions via automatic or implicit processing. The “framing effect” is considered to capture implicit effects of task‐irrelevant emotional stimuli on decision‐making. We hypothesized that cardiac awareness, as a measure of interoceptive skills, is positively associated with susceptibility to the framing effect. Forty volunteers performed a risky‐choice framing task in which the effect of loss versus gain frames on decisions based on identical information was assessed. The results show a positive association between cardiac awareness and the framing effect, accounting for 24% of the variance in the framing effect. These findings demonstrate that good interoceptive skills are linked to poorer performance in risky choices based on ambivalent information when implicit bias is induced by task‐irrelevant emotional information. These findings support a dual process perspective on decision‐making and suggest that interoceptive skills mediate effects of implicit bias on decisions.  相似文献

ABSTRACT

This paper documents preliminary examination of the factor structure and psychometric properties of the Parental Attitudes and Behaviors Scale (PABS), an OCD-specific measure of parental attitudes, beliefs, and behavioral strategies related to childhood OCD. Employing a sample of 123 youth (mean age = 11.7; 59% male, 79% Caucasian) diagnosed with OCD in an outpatient child anxiety clinic, we used exploratory factor analysis to produce a 3-factor solution representing the following domains of parental responses to childhood OCD: accommodation, empowerment, and hostility/blame. These scales demonstrated adequate internal consistency and concurrent validity, providing preliminary evidence for the psychometric integrity of the PABS.  相似文献

Abstract

The clinical and psychosocial effects of immediate penile prosthesis implantation at the time of radical prostatectomy (RP) were investigated in 97 consecutive patients and 68 partners. Prosthesis recipients reported more frequent sexual contact, fewer marital problems and slightly fewer sexual functioning problems than the RP-alone patients. There were no group differences on any sociodemographic characteristics, on disease recurrence, on physical and psychosocial functioning, or on reported depression. Patients who chose the prosthesis did, however, evidence less of a link between depression and functional limitations and between depression and marital problems. They also had lower levels of agreement with their partners in reporting their own depression, as compared to the patients who opted for RP surgery alone. We conclude that the penile prosthesis was associated with an increased frequency of sexual contact, a reduction in reported marital problems, and stylistic differences between the two patient groups in dealing with affect.  相似文献

Stress and self‐esteem have been shown to be important risk factors for adolescent cigarette smoking, and self‐esteem has previously been implicated as a stress‐moderating and a stress‐mediating variable. This study aimed to examine the associations between stress, area‐specific self‐esteem, and adolescent smoking, and to investigate whether specific areas of self‐esteem moderate or mediate the relationship between stress and smoking. Four hundred and ninety‐five adolescents (aged 14–19) responded to a questionnaire that examined these variables. Results showed that self‐esteem in the areas of school subjects and parent relations were related to smoking. Adolescents with low self‐esteem in these areas were more likely to smoke than their high self‐esteem counterparts. Highly stressed adolescents were more likely to smoke than those with low stress. However, the relationship between stress and smoking was completely mediated by self‐esteem in the area of school subjects. No moderation was revealed. Thus, high global self‐esteem may not be sufficient to reduce the risk of smoking. To maximise benefit, prevention and intervention efforts should target self‐esteem in the areas of school subjects and parent relations. Initiatives focusing on stress are only likely to decrease smoking to the extent that they influence self‐esteem in the area of school subjects.  相似文献

This collective case study applied life design counselling to augment the career adaptability of learners in a South African independent school setting. Five purposively selected learners attending Grade 11 (age range: 16–18) completed eight group-based life design counselling sessions. Data on their career adaptability pre- and post-intervention were gathered from sessional notes. The data were thematically analysed. Following the intervention the participants displayed improved career adaptability as evidenced by their demonstrated efforts to address aspects related to career concern, control, curiosity and confidence. Life design counselling appeared to have a positive effect on the career adaptability of learners in an independent school setting.  相似文献

Many of today's monks and nuns are active composers: some have entered their communities as highly trained musicians, while others find themselves drawn to musical expression after profession. But how does such a creative musical response relate to the monastic atmosphere of hesychia (prayerful silence), and does this response differ in secular experiences of a prayerful silence? This paper provides an ethnographic account of the relationship between hesychia and creative response among twenty-first-century monastic musicians in the Western tradition, comparing these responses with those from secular Christian composers and from composers in the Quaker tradition for whom silence is, as for monastics, an integral component of worship; the issues are then explored in the context of methodological constructs for discursive meditation and contemplative prayer, and of conceptual notions of silence. This paper argues that essential differences between monastic and secular experiences of silence are significant regulators of creative response to hesychia.  相似文献

Parent–child reminiscing conversations in early childhood have received theoretical attention as a forum for children's self‐concept development, but this has been little addressed in empirical work. This study examines associations between emotion reminiscing and children's self‐concepts and, building from the reminiscing and personality development literatures, also explores the role of children's coping. Sixty 4‐ and 5‐year‐old children and their mothers completed reminiscing conversations about events in which the child had experienced negative emotion, children completed an age‐appropriate assessment of their self‐concept, and mothers and teachers reported on children's coping strategies. Children's self‐perceived timidity was associated with their explanations for negative emotions during reminiscing. Children's self‐perceived negative affect was associated with fewer emotion resolutions during reminiscing, and with distinctive patterns of coping. Both reminiscing and coping made unique contributions to children's self‐concepts, and findings also suggest that coping may in some contexts indirectly connect reminiscing with self‐concept. These findings suggest that reminiscing conversations both reflect children's characteristics and provide a context for learning about their characteristics, along with strategies for emotion management.

Research on the effect of paternal mental health problems, particularly on young children, is based predominantly on clinical levels of depression. Furthermore, potential mediators such as marital discord have often been overlooked. This longitudinal community study assessed the association between paternal mental health symptoms in a community sample (N = 705) assessed at 3 months postnatally (Edinburgh Postnatal Depression Scale) and 36 months (General Health Questionnaire) and children's socio‐emotional and behavioural problems at 51 months (Strengths and Difficulties Questionnaire) as reported by mother, father and teacher. Controlling for socioeconomic status and maternal mental health symptoms at 3 and 36 months, paternal postnatal depressive symptoms predicted more father‐reported child problems at 51 months but, in contrast to previous findings, not mother‐reported problems. Paternal mental health symptoms at 36 months predicted both maternal and paternal reports of child problems at 51 months controlling for both paternal and maternal postnatal symptoms. Paternal mental health symptoms at 3 and 36 months were not significant predictors of teacher‐reported child problems. Postnatal marital discord and paternal mental health problems at 36 months both mediated the relationship between paternal postnatal symptoms and later child emotional and behavioural problems. Child gender did not moderate the relationship. Implications for interventions are discussed. Copyright © 2013 John Wiley & Sons, Ltd.  相似文献

This study examined the contribution of child temperament, parenting, and their interaction on inhibitory control development in a sample of maltreated and non‐maltreated preschool children. One hundred and eighteen mother–child dyads were drawn from predominantly low‐income, rural communities. Dyads participated in a laboratory session in which maternal warm autonomy support, warm guidance, and strict/hostile control were observationally coded during a joint teaching task. Independent assessments of children's inhibitory control were obtained, and observers rated children's temperament. After relevant covariates, including income, maternal education, and child age and IQ were controlled for, there were no differences between the maltreatment and non‐maltreatment groups in either children's inhibitory control or mothers' behaviours in the laboratory session. Even after much of the variance in children's inhibitory control was accounted for from the covariates, children's temperamental negativity moderated the effects of warm autonomy support on inhibitory control in both maltreatment and non‐maltreatment groups. Temperamentally negative children whose mothers displayed more warm autonomy support showed greater inhibitory control, at levels on par with low‐negative children. Findings suggest that heterogeneity in children's self‐regulation may be due in part to individual differences in sensitivity to caregiver support for children's independence, even among those exposed to maltreatment.
