Sykes and Matza argued that delinquents use techniques of neutralization to enable themselves to engage in behavior they believe is wrong under most circumstances. One function of using these techniques is that the individual is able to protect his or her self-concept while committing delinquent acts. This implies that delinquent youth who use these techniques should have higher levels of self-esteem than delinquents who do not use them. Because Sykes and Matza hold that neutralization is necessary because of the delinquents ties to conventional society, this effect should be stronger among delinquent youth who are more strongly attached to their parents. In contrast, Hirschis social control theory predicts that delinquents who are able to maintain a bond to conventional society should be less likely to neutralize, but if they do neutralize, they should be unable to sufficiently convince themselves of the validity of the neutralizations to protect self-esteem. These hypotheses are tested using data from the Richmond Youth Survey. The results differed depending on whether general neutralizations or neutralizations regarding the police were analyzed. Children who are attached to their parents are less likely to use police-related neutralizations, but delinquents who use these neutralizations have higher self-esteem, consistent with neutralization theory. Delinquents who are more strongly attached to their parents are also less likely to use general neutralizations, but these neutralization techniques do not lead to higher levels of self-esteem, consistent with control theory.  相似文献

The current study investigated the effects of context length on the processing of novel words. Participants read real adjectives or novel words embedded in either sentence or paragraph contexts while their eye movements were recorded. The results extend the literature on novel word reading by exploring the time‐course of word processing using realistic contexts derived from existing sources. Eye‐movement measures demonstrated that readers were very sensitive to the presence of novel words. Novel words were more likely to be fixated and had longer reading times than real words. In addition, words in sentence contexts had longer gaze durations than words in paragraphs. The effect of novelty on reading the target word did not vary as a function of the context length. While performance on the surprise post‐test did not demonstrate significant word learning, participants did report higher confidence in correct responses than incorrect, suggesting that some learning took place.  相似文献

Most theories addressing the topic have proposed that threat and fear underlie right‐wing authoritarianism (RWA), and many empirical findings have been consistent with this proposition. Important questions, however, remain unanswered, such as whether RWA is associated with fear and threat in general or only specific kinds of fear and threat. Theories of RWA generate markedly different predictions on this issue, particularly with respect to social or personal fears, and whether the association would also hold for the closely related construct of social dominance orientation (SDO). We investigated the issue by asking 463 undergraduate students to rate their feelings of fear, concern, and anxiety to a comprehensive 93‐item list of potential fears and threats, which were formulated as either personal or social. Exploratory factors analysis identified five distinct fear–threat factors: Harm to Self, Child, or Country; Personal and Relationship Failures; Environmental and Economic Fears; Political and Personal Uncertainties; and Threats to Ingroup. All the fear–threat factors were correlated with RWA, with the strongest correlations being for Threats to Ingroup, and with stronger effects for social than for personal fears. None of the fear factors correlated with SDO. These relationships were not affected by controlling for Social Desirability or Emotional Stability (EMS). When the intercorrelations between fear factors and EMS were controlled using ridge regression, only Threats to Ingroup predicted RWA. Structural equation modeling indicated good fit for a model in which low levels of EMS had a significant path to Threats to Ingroup, which in turn had a significant path to RWA, and EMS having a significant though weak indirect (fully mediated) inverse effect on RWA. Implications of these findings for theories of authoritarianism and future research are discussed.  相似文献

Cognitive, comparative, and developmental psychologists have long been intrigued by humans’ and animals’ capacity to respond to abstract relations like sameness and difference, because this capacity may underlie crucial aspects of cognition like analogical reasoning. Recently, this capacity has been explored in higher-order, relational matching-to-sample (RMTS) tasks in which humans and animals try to complete analogies of sameness and difference between disparate groups of items. The authors introduced a new paradigm to this area, by yoking the relational-matching cue to a perceptual-matching cue. Then, using established algorithms for shape distortion, the perceptual cue was weakened and eliminated. Humans’ RMTS performance easily transcended the elimination of perceptual support. In contrast, RMTS performance by six macaques faltered as they were weaned from perceptual support. No macaque showed evidence of mature RMTS performance, even given more than 260,000 training trials during which we tried to coax a relational-matching performance from them. It is an important species difference that macaques show so hesitant a response to conceptual relations when humans respond to them so effortlessly. It raises theoretical questions about the emergence of this crucial capacity during humans’ cognitive evolution and during humans’ cognitive development.  相似文献

Rationale: Carers of people with dementia experience significant levels of stress in their everyday role. The National Dementia Strategy in England identifies the key role that carers play in supporting people with dementia living at home, often to the detriment of their social, emotional and physical health. Aims: To add to the substantive knowledge‐base by combining search criteria used by Pinquart and Sörensen (2006) and Gallagher‐Thompson and Coon (2007) to update the literature on psychological interventions for carers of people with dementia published between 2005 and 2011. Method: Following the study inclusion criteria, comprehensive searches were conducted using the electronic databases Medline, PsycINFO, ERIC, and PubMed. Twenty studies were identified, graded and synthesised into the reported systematic review with both quantitative and qualitative studies included to maximise practice application. Results: Consistent with previous findings, three categories of psychological intervention were identified: (i) psychoeducational‐skill building (n=8); (ii) psychotherapy‐counselling (n=1); (iii) multicomponent (n=6). Our review also identified a fourth intervention category, (iv) technology‐based (n=5). The majority of studies in the updated review examine the constructs of depression, burden, social support and well‐being. The development of focused interventions for carers, whether individually tailored interventions or group interventions around a common issue, was significant for developing practice. Future studies across all categories should continue to embed supervision arrangements within their psychological intervention protocols.  相似文献

Abstract

This paper looks at two GPs' surgeries and the way that they deal with the anxieties aroused when trying to meet patients' needs in primary health care. The practice counsellor is both an observer and a participant in this. The physical surroundings seem to influence the way these anxieties are acted out. Each surgery has to create an enemy in order to live with their anxiety.  相似文献

The current study explores the impact of HIV disease on the interpersonal relationships and social support experiences of mothers living with HIV. Analysis of interviews with 25 mothers with HIV focused on their perceptions of the impact of HIV on close relationships with significant others, including family of origin, children, friends, intimate partners, and parents. The results revealed the following major relationship challenges that mothers had to cope with after the discovery of their HIV-positive status: weighing reasons for and against disclosure of their HIV status, whether HIV disclosure brings relationship partners closer together, finding future caregivers for young children if one's health declines, and coordinating safer-sex practices with sexual partners, especially with the many males who are reluctant to use condoms. The study suggests the importance of understanding both the positive and negative aspects of social interactions in coping with HIV and the struggles that mothers have with the consequences of the HIV diagnosis for both themselves and their significant others.  相似文献

Residents experience severely high levels of stress, depression and burnout, leading to perceived medical errors, as well as to symptoms of impairment, such as chronic anger, cognitive impairment, suicidal behavior and substance abuse. Because research has not yet provided a psychometrically robust population-specific tool to measure the level of stress of medicine residents, we aimed at building and validating such a measure. Using an inductive scale development approach, a short, pragmatic measure was built, based on the interviews of 17 medicine residents. The Internal Medicine Residency Stress Scale (IMRSS) was then administered in a sample of 259 internal medicine residents (199 females, 60 males, MAge = 25.6) along with the Hospital Anxiety and Depression Scale, Maslach Burnout Inventory, Satisfaction With Life Scale and Ways of Coping Checklist. The IMRSS showed satisfactory internal reliability (Cronbach’s α = .86), adequate structural validity – studied through Confirmatory Factor Analysis (χ2/df = 2.51, CFI = .94; SRMR = .037, RMSEA = .076) – and good criterion validity – the IMRSS was notably strongly correlated with emotional exhaustion (r = .64; p < .001) and anxiety (r = .57; p < .001). Because of its short length and robust psychometric qualities, the use of the IMRSS is recommended to quickly and frequently assess and monitor stress among internal medicine residents.  相似文献
