Adult CD-1 male mice were gonadectomized and tested for their response to the aggression-promoting property of androgens, estrogens, or combined androgen-estrogen treatment. The results showed that the combined treatment was the most effective, although androgens alone were sufficient for behavioral restoration. These findings suggest that testosterone may activate aggression through both its androgenic and estrogenic metabolites. 相似文献

The dynamic representation of pairs of intensity judgement responses to two-component odour mixtures, composed of various concentrations of bergamote and amyl acetate, is explored using multivariate time series analysis and the associated root locus diagrams derived from factoring a polynomial determinant of the matrix polynomial z-transformation of the system transfer function. The topology of the root loci is examined for both pseudocoupled and really coupled conditions, to see how the component odourants interact in determining the psychophysics of odour mixture perception. It is shown that most subjects show a loss in gain for both components, but that they are not dynamically homogeneous. Third-order loop gain equations are a sufficient representation in nearly all cases. 相似文献

Illness Perceptions,Coping, Benefit Finding,and Adjustment in Individuals with Hepatitis C 下载免费PDF全文
Objective
To investigate the ability of illness perceptions, adaptive, and maladaptive coping strategies, and benefit finding to predict physical and psychosocial adjustment among individuals diagnosed with the hepatitis C virus (HCV), within an expanded self‐regulatory model of illness (SRM).Method
A total of 126 participants with HCV completed an online questionnaire assessing illness perceptions, coping, benefit finding, and four adjustment outcomes, depression, physical functioning, life satisfaction and positive affect.Results
Illness perceptions made significant contributions to the variance in adjustment outcomes across the four psychosocial and physical adjustment areas. At an individual level, personal control, identification with HCV symptoms, perceptions related to illness duration, illness coherence, and emotional responses to HCV made significant contributions to the prediction of adjustment. Similarly, the combined contributions of adaptive and maladaptive coping strategies explained significant variance across the four adjustment areas. Greater adoption of maladaptive coping strategies predicted poorer physical health, higher reported depression, greater life satisfaction, and positive affect outcomes, while increased engagement with adoptive coping strategies predicted higher positive affect. Increased benefit finding predicted greater positive affect, life satisfaction, and higher depression.Conclusion
Results demonstrate the ability of the SRM features of illness perceptions and coping, and benefit finding to predict physical and psychosocial adjustment outcomes within the context of HCV. 相似文献997.

This paper is a contribution to a book symposium on my book Experiencing Time. I reply to comments on the book by Natalja Deng, Geoffrey Lee and Bradford Skow. Although several chapters of the book are discussed, the main focus of my reply is on Chapters 2 and 6. In Chapter 2 I argue that the putative mind-independent passage of time could not be experienced, and from this I develop an argument against the A-theory of time. In Chapter 6 I offer one part of an explanation of why we are disposed to think that time passes, relating to the supposedly ‘dynamic’ quality of experienced change. Deng, Lee, and Skow’s comments help me to clarify several issues, add some new thoughts, and make a new distinction that was needed, and I acknowledge, as I did in the book, that certain arguments in Chapter 6 are not conclusive; but I otherwise concede very little regarding the main claims and arguments defended in the book. 相似文献

Phenylketonuria (PKU) is a rare inherited metabolic disorder which can cause neurological damage if left untreated. PKU is identified through newborn screening in developed countries, and treatment begins immediately to prevent these severe consequences. When a child is diagnosed, parents must assume immediate responsibility for the management of PKU and prevention of neurological damage. Quantitative studies have identified significant psychosocial stressors for parents, but little is known about how the parents experience this process. This study aimed to explore the experiences of parents of children with PKU under the age of two. It is the first study to examine these experiences in this way. Seven parents were interviewed about their experiences, and interpretative phenomenological analysis was used to analyse the data. Three main themes were identified: control, striving for normality and acceptance of PKU as a continuum. Links between the themes and processes underpinning the results were explored with relation to existing literature and theories from a clinical psychology perspective. The role of acceptance of PKU was central to the parent’s experiences. Clinical implications and suggestions for further research are discussed. 相似文献

Rummage search is the visual and haptic search of complex environments for targets. In this study, rummage search was explored using a novel analytic framework with expert dyads and novice dyads, as well as novice individuals. Participants sought an unknown number of targets placed in four rooms of a residential house. Some targets were plainly visible whereas others were hidden and could only be found through haptic examination. Expert dyads were very good at the task, conducting a slowed, double-checking exhaustive search, while novices both failed to fixate potential target locations and failed to carry out the appropriate action required to search those locations exhaustively. The novice dyads examined more than the novice individuals, but became more superficial in their search. We conclude that effective rummage searching is a skill enhanced by training. 相似文献
