Two studies investigated the impact of affective and cognitive messages compared to a no-message control on self-reported exercise. Students (Study 1, N = 383 and Study 2, N = 197) were randomly allocated to one of the three conditions (control - no message, affective message or cognitive message). Participants completed questionnaire measures tapping components of the theory of planned behaviour in relation to exercise and reported their level of exercise (3 weeks later). In Study 2, measures of need for affect (NFA) and need for cognition (NFC) were also completed. Results showed that affective messages consistently produced greater increases in self-reported level of exercise than the other conditions. In both studies, this effect was partly mediated by affective attitude change. Study 2 indicated these effects to be significantly stronger among those high in NFA or low in NFC. These findings indicate the value of affective messages that target affective attitudes in changing exercise behaviour. 相似文献

Recent factor analytic studies in Attention-Deficit/Hyperactivity Disorder (ADHD) have shown that hierarchical models provide
a better fit of ADHD symptoms than correlated models. A hierarchical model includes a general ADHD factor and specific factors
for inattention, and hyperactivity/impulsivity. The aim of this 12-month longitudinal study was to test the generalizability
of the hierarchical models of ADHD within an elementary school population of 6–9 year old children (250 boys, 260 girls).
Examination of differences as a function of informant (parent vs. teacher ratings), sex, and time was conducted. Six potential
factor structures for the 18 items of the SWAN (Strengths and Weaknesses of ADHD-symptoms and Normal-behavior) scale were tested using confirmatory and exploratory factor analyses. Hierarchical models with a general ADHD
factor and two or three specific factors best accounted for parent and teacher reports of symptoms for both boys and girls
and at two time points separated by a 12-month interval. Findings indicate that the 18 SWAN items measure a common latent
trait as well as orthogonal factors or dimensions of inattention and hyperactivity/impulsivity. 相似文献

Objective: To examine factor structures of Diagnostic and Statistical Manual of Mental Disorders (4th ed.) symptoms of ADHD in adults. Method: Two sets of models were tested: (a) models with inattention and hyperactivity/impulsivity as separate but correlated latent constructs and (b) hierarchical general factor models with a general factor for all symptoms and separate specific factors for inattention and hyperactivity/impulsivity. Participants were 751 adults with ADHD. Two models with correlated factors and two general factor models of ADHD symptoms were tested. Results: The general factor model provided a better fit of the data than the correlated models. The general factor model with one general and three (inattention, motoric, and verbal hyperactivity/impulsivity) specific factors best accounted for the adults' symptoms. Conclusion: These results suggest a unitary component to ADHD symptoms as well as dimensional specific factors. The replication of a general factor in adults suggests continuity of symptom presentation from childhood into adulthood. Clinical implications are discussed. 相似文献

In this article I consider the implications of our differing psychoanalytic theories of anxiety on clinical technique. Drawing on differentiations between the focus on separation or castration anxiety and the relative neglect of the latter in contemporary writing, I look in detail at two clinical examples of psychoanalysis in borderline young adults to exemplify the issue. 1 相似文献

Most moral philosophers agree that if a moral agent is incapable of performing some act ф because of a physical incapacity, then they do not have a reason to ф. Most also claim that if an agent is incapable of ф-ing due to a psychological incapacity, brought about by, for example, an obsession or phobia, then this does not preclude them from having a reason to ф. This is because the ‘ought implies can’ principle is usually interpreted as a claim about physical, rather than psychological, capacities. In this paper I argue for an opposing view: if we don’t have reasons to do things that we are physically incapable of doing, then neither do we have reasons to do things we are psychologically incapable of doing. I also argue that extending the ‘ought implies can’ principle to psychological capacities makes the principle more attractive. 相似文献

Studies of contagious yawning have reported inconsistent findings regarding whether dogs exhibit this behavior and whether it is mediated by social-cognitive processes or the result of physiological arousal. We investigated why some dogs yawn in response to human yawns; particularly, whether these dogs are exceptional in their ability to understand human social cues or whether they were more physiologically aroused. Sixty shelter dogs were exposed to yawning and nonyawning control stimuli demonstrated by an unfamiliar human. We took salivary cortisol samples before and after testing to determine the role of arousal in yawn contagion. Dogs were tested on the object-choice task to assess their sensitivity for interpreting human social cues. We found that 12 dogs yawned only in response to human yawns (i.e., appeared to exhibit yawn contagion), though contagious yawning at the population level was not observed. Dogs that exhibited yawn contagion did not perform better on the object-choice task than other dogs, but their cortisol levels remained elevated after exposure to human yawning, whereas other dogs had reduced cortisol levels following yawning stimuli relative to their baseline levels. We interpret these findings as showing that human yawning, when presented in a stressful context, can further influence arousal in dogs, which then causes some to yawn. Although the precise social-cognitive mechanisms that underlie contagious yawning in dogs are still unclear, yawning between humans and dogs may involve some communicative function that is modulated by context and arousal. 相似文献
