Habit and motivation are thought to be separate processes, with motivated behavior often considered to be goal directed, whereas habits are defined by the absence of goal-directed control over behavior. However, there has been increasing interrogation of the binary nature of habitual versus goal-directed behavior. Furthermore, although drug and alcohol exposure can promote the formation of habits, drug seeking itself can also be highly flexible, pointing toward the need for complex consideration of the parallel processes that drive behavior. The goal of the current study was to determine whether there was a relation between motivation—as measured by progressive ratio—and habit—as measured by contingency degradation—and whether this relation was affected by ethanol exposure history and sex. The results showed that these measures were positively correlated such that greater contingency insensitivity was associated with achieving higher break points on the progressive-ratio task. However, this relation depended on reinforcement schedule history, ethanol exposure history, and sex. These point to potential relations between measures of habit and motivation and stress the importance of carefully parsing behavioral findings and assays. These findings are also expected to inform future substance use research, as drug history may affect these relations. 相似文献

Objectives
To explore English and Spanish fans’ emotional responses to team success and failure and resulting changes in social interaction and spending during the 2010 Soccer World Cup.Design
A between-group and within-group longitudinal design.Method
Data on emotion, team identification, social interaction and spending were collected from 59 English fans (47 men, 12 women), and 32 Spanish fans (19 men, 13 women), before, during and after the 2010 Soccer World Cup.Results
Both English and Spanish fans displayed significant changes in emotional state after the success or failure of their respective teams during the Soccer World Cup. The positive emotional state associated with winning the tournament in the Spanish fans persisted for over four days, and the negative emotional state associated with the early exit from the tournament by the English fans did not. Four days after the tournament the Spanish Fans had a more positive emotional state than the English fans. The changes in emotional state were not associated with greater identification with the team assessed through the use of team identifying pronouns; nor were changes in behavior associated with changes in emotional state. After the tournament the Spanish fans reported spending more time socializing than English fans and also spending more money than usual compared with baseline.Conclusion
These data provide evidence that group membership influences emotion and that the positive emotional experience associated with group success persist longer than the negative emotional experience associated with group failure. 相似文献55.

Women of lower educational attainment are more likely to eat unhealthy diets than women of higher educational attainment. To identify influences on the food choices of women with lower educational attainment, 11 focus groups (eight with women of lower, and three with women of higher educational attainment) were held. Using a semi-structured discussion guide, environmental, social, historical and psychological factors known to be associated with food choice were explored. Audio recordings were transcribed verbatim and thematically analysed. Compared to women of higher educational attainment, women of lower educational attainment had less control over their families’ food choices, less support for attempts to eat healthily, fewer opportunities to observe and learn good food-related practices, more negative affect, more perceived environmental constraints and more ambiguous beliefs about the consequences of eating a nutritious diet. These findings provide a starting point for taking forward the design of an intervention to improve the diets of young women. 相似文献

Single-case research methods are an important facet of applied sport psychology because they provide a framework for researchers and practitioners to outline intervention effects across time with individuals or groups. This paper reviews the research published since Hrycaiko and Martin's (1996) milestone overview of single-case research in sport psychology. Specifically, we examined the literature between 1997 and 2012 and located 66 studies that met our inclusion criteria of assessing interventions in sport psychology. The review summarizes the body of research, outlines trends, considers the limitations of the extant literature, and identifies areas that require further investigation for future single-case research. 相似文献

Transplantation continues to push the frontiers of medicine into domains that summon forth troublesome ethical questions. Looming on the frontier today is human facial transplantation. We develop criteria that, we maintain, must be satisfied in order to ethically undertake this as-yet-untried transplant procedure. We draw on the criteria advanced by Dr. Francis Moore in the late 1980s for introducing innovative procedures in transplant surgery. In addition to these we also insist that human face transplantation must meet all the ethical requirements usually applied to health care research. We summarize the achievements of transplant surgery to date, focusing in particular on the safety and efficacy of immunosuppressive medications. We also emphasize the importance of risk/benefit assessments that take into account the physical, aesthetic, psychological, and social dimensions of facial disfiguration, reconstruction, and transplantation. Finally, we maintain that the time has come to move facial transplantation research into the clinical phase. 相似文献

The standard view about counterfactuals is that a counterfactual (A > C) is true if and only if the A‐worlds most similar to the actual world @ are C‐worlds. I argue that the worlds conception of counterfactuals is wrong. I assume that counterfactuals have non‐trivial truth‐values under physical determinism. I show that the possible‐worlds approach cannot explain many embeddings of the form (P > (Q > R)), which intuitively are perfectly assertable, and which must be true if the contingent falsity of (Q > R) is to be explained. If (P > (Q > R)) has a backtracking reading then the contingent facts that (Q > R) needs to be true in the closest P‐worlds are absent. If (P > (Q > R)) has a forwardtracking reading, then the laws required by (Q > R) to be true in the closest P‐worlds will be absent, because they are violated in those worlds. Solutions like lossy laws or denial of embedding won't work. The only approach to counterfactuals that explains the embedding is a pragmatic metalinguistic approach in which the whole idea that counterfactuals are about a modal reality, be it abstract or concrete, is given up. 相似文献

Children growing up in disharmonious families with anxious/depressed mothers are at risk for emotional and behavioral difficulties,
however whether these associations reflect postnatal environment, prenatal exposure, or an overall liability is still unclear.
This study used prospectively collected data from 24,259 participants of the Norwegian Mother and Child Cohort Study (MoBa).
Mothers reported on anxiety/depression and family disharmony twice in pregnancy and twice post pregnancy, as well as on their
child’s physical aggression and crying behavior at age 36 months. First, results from an autoregressive cross-lagged model
showed a substantial stability in both maternal anxiety/depression and family disharmony from pregnancy to 18 months postnatal,
but there was no indication that family disharmony led to maternal anxiety/depression, or the other way around. Second, structural
equation models further suggests that the main risk derived from an overall liability, that is, a lasting effect of family
risks that spanned the two time periods. 相似文献

There is growing evidence that among the different conduct disorder (CD) behaviors, physical aggression, but not theft, links to low neurocognitive abilities. Specifically, physical aggression has consistently been found to be negatively related to neurocognitive abilities, whereas theft has been shown to be either positively or not related to neurocognition. The specificity of these links needs further examination because attention deficit hyperactivity disorder (ADHD) links to both physical aggression and neurocognitive variation. The development of self-reported physical aggression and theft, from age 11 to 17 years, was studied in a prospective at-risk male cohort via a dual process latent growth curve model. Seven neurocognitive tests at age 20 were regressed on the growth parameters of physical aggression and theft. The links between neurocognition and the growth parameters of physical aggression and theft were adjusted for ADHD symptoms at ages 11 and 15 (parent, child and teacher reports). Results indicated that verbal abilities were negatively related to physical aggression while they were positively associated with theft. However, inductive reasoning was negatively associated with increases in theft across adolescence. Symptoms of ADHD accounted for part of the neurocognitive test links with physical aggression but did not account for the associations with theft. These differences emphasize the importance of examining specific CD behaviors to better understand their neurodevelopmental mechanisms. They also suggest that youth who engage in different levels of physical aggression or theft behaviors may require different preventive and corrective interventions. 相似文献
