Auditory thresholds have been determined for the goldfish by six groups of workers and the data in the experiments varied by as much as 20–30 dB. In order to isolate the basis for this variability, auditory thresholds were determined using conditioned suppression of respiration and method of limits. These thresholds were very similar to those obtained with avoidance conditioning and a tracking method for threshold determination. Acoustic procedures were kept constant in the two series of experiments, and it appears that wide variation in auditory thresholds for goldfish shown in different experiments is due to acoustic conditions in the experiments.  相似文献

Psychological effects of running loss on consistent runners   总被引:5,自引:0,他引:5  
This study examined the psychological effects of running loss upon consistent runners. We compared a group of 30 "Prevented Runners" who were unable to run for at least two weeks with a group of 30 "Continuing Runners" who ran without interruption on the Profile of Mood States (POMS), Rosenberg Self-esteem Scale, Zung Depression Scale, and a Running Information questionnaire. We found that Prevented Runners displayed significantly greater symptoms of psychological distress, including depression, anxiety, confusion, over-all mood disturbance, and lower self-esteem than did Continuing Runners. Deprivation of running may result in withdrawal symptoms of psychological distress for consistent runners who rely on running as a coping strategy for stress reduction and who feel dependent upon the psychological reinforcements of running.  相似文献

It was hypothesized that the population of pedophiles differs from that of males who prefer physically mature partners, in respect of the proportion of bisexual members in each group. Bisexuality was assessed by means of a verbal scale and by recording penile volume changes during the presentation of movie clips of nude males and females. Results supported the hypothesis.An earlier finding of a difference between pedophiles and males who prefer physically mature partners, in respect to feminine gender identity, was retested using the Feminine Gender Identity Scale (for males). It could be confirmed only for homosexual males and therefore cannot be accepted as a general difference between pedophiles and persons who prefer physically mature partners.  相似文献

Although counselors in 44 states are mandatory reporters of child maltreatment, they may lack an understanding of their legally designated role. This article presents the results of a systematic review of child maltreatment reporting laws in all 50 states and the District of Columbia. The authors apply relevant legislation to real‐life contexts for counselors.  相似文献

This paper presents the process of how partnerships are established between an urban residential community and an academic institution in Malaysia by employing community‐based participatory research, which involves researchers, community members, and organizational representatives as coresearchers. The research process encompasses colearning, power sharing, and coconstructing of knowledge, with the community members driving the research direction. The research paradigm is grounded on conducting research with the community. This paper highlights the experience and lessons learned while applying the principles of community‐based participatory research that promotes social participation of older persons living in a residential community. Two pertinent challenges surface in the research process. The first challenge involves the complexity noted in the gap between the emancipation of community‐based participatory research and the hierarchical social structure of the society. The second challenge is the prevalence of unspoken yet subtle domination that undermines the local cultural values affecting the process of coconstructing knowledge with the community. Recommendations for addressing these challenges include future partnerships with other Malaysian communities as well as cross‐border research partnerships.  相似文献
