The terms "appropriate" and "necessary" are crucial determinants in decisions regarding the use and reimbursement of medical treatments. This paper encourages greater awareness of the political, economic, and normative assumptions that give meaning to these concepts. 相似文献

Piaget suggests that animistic thinking is a pervasive feature of children's cognition. To test this notion, 4- to 8-year-old children were shown several inanimate objects and asked to pick those which perform activities characteristic of living organisms. These activities were typified by six verbs: eat, sleep, breathe, grow, die,, and be alive. Fifty percent of the younger children responded animistically, by misattributing life processes to inanimate objects, but only 18% of their total responses were animistic. Twenty percent of the older children responded animistically, but only 20% of their responses were animistic. In Experiment II, children were shown drawings singly and asked if the object could perform activities named by one of the six verbs. Results were similar to those of Experiment I but with somewhat less animism. Experiment III required children to spontaneously name things that are alive. There were no animistic responses. It was concluded that animistic thinking is not a genuine phenomenon but linguistic confusion elicited by novel objects and unfamiliar words.This work was supported by NSF Grant GB 23083.A portion of the data of Experiment I constituted a Bachelor Honors Thesis conducted by the first author under the direction of the second and submitted to Florida State University. These data were presented at the meeting of the Southeastern Psychological Association, New Orleans, April 1973. 相似文献

This study consists of four factor analyses of the Army Air Forces Aircrew Classification Batteries. The first was an analysis of the 1945 wartime battery, while the other three were analyses of the 1947 postwar battery, consisting of essentially the same variables, but using different samples. Eleven factors were found which had been identified and reported in previous analyses. An additional factor, possibly an artifact, was identified as an age-education doublet. The only factor which differed significantly in the analyses was pilot or flying interest. These factor analyses show that the factorial content of the tests remains quite similar in both wartime and postwar populations.The data reported in this study were collected as part of the United States Air Force Human Resources Research and Development Program and described in Research Bulletin 52-16. The opinions or conclusions contained in this report are those of the authors. They are not to be construed as reflecting the view or indorsement of the Department of the Air Force. 相似文献

Observers judged whether a periodically moving visual display (point-light walker) had the same temporal frequency as a series of auditory beeps that in some cases coincided with the apparent footsteps of the walker. Performance in this multisensory judgment was consistently better for upright point-light walkers than for inverted point-light walkers or scrambled control stimuli, even though the temporal information was the same in the three types of stimuli. The advantage with upright walkers disappeared when the visual "footsteps" were not phase-locked with the auditory events (and instead offset by 50% of the gait cycle). This finding indicates there was some specificity to the naturally experienced multisensory relation, and that temporal perception was not simply better for upright walkers per se. These experiments indicate that the gestalt of visual stimuli can substantially affect multisensory judgments, even in the context of a temporal task (for which audition is often considered dominant). This effect appears to be constrained by the ecological validity of the particular pairings. 相似文献

We describe over 300,000 crisis calls made to a large national hotline over a 5-year period. Callers consisted of males and
females between the ages of 10 and 89. Overall, a slight majority of callers were first time callers (52%) and most (73%)
sought assistance with issues related to parenting, youth concerns, and mental health. Across the lifespan, issues dealing
with loneliness increased with age whereas depression-related calls decreased. Additionally, females were more likely than
their male counterparts to call the hotline by over a 2- to 1-margin. Findings lend preliminary support to the efficacy of
crisis call centers to utilize a flexible, yet well-defined problem-solving approach to assist those of all ages calling with
the wide range of problems. 相似文献

Previous research has shown that we recognize faces similar in age to ourselves better than older or younger faces (e.g.,
Wright & Stroud, 2002). This study investigated whether this own-age bias could be explained by the contact hypothesis used to account for the own-race bias (see Meissner & Brigham, 2001). If the own-age bias stems from increased exposure to
people of our own age, it should be reduced or absent in those with higher exposure to other age groups. Participants were
asked to remember facial photographs of 8- to 11- and 20- to 25-year-olds. Undergraduates were faster and more accurate at
recognizing faces of their own age. However, trainee teachers showed no such own-age bias; they recognized the children’s
faces more quickly than own-age faces and with comparable accuracy. These results support a contact-based explanation of the
own-age bias. 相似文献

Morningness/eveningness, morning-to-afternoon cortisol ratio, and antisocial behavior problems during puberty 总被引:1,自引:0,他引:1

The relationship between morningness/eveningness (M/E) and morning-to-afternoon cortisol ratio, pubertal timing, and antisocial behavior was examined in 111 girls and boys ages 8 to 13 years. Cortisol levels showed a significant increase after awakening and declined thereafter (p<.05). Eveningness was related to a composite measure of antisocial behavior and rule-breaking and attention behavior problems and conduct disorder (CD) symptoms in boys and relational aggression in girls. In boys only, lower a.m. to p.m. cortisol ratio, indicating less circadian decrease in cortisol, was related to attention problems. Early pubertal timing was associated with boys' rule-breaking and attention behavior problems and CD symptoms and girls' relational aggression. The findings indicate that evening activity preference; extreme a.m. to p.m. cortisol ratios, in one case; and early pubertal timing were associated with antisocial behavior even in young adolescents, but the findings were stronger for boys than for girls. 相似文献

To determine the underlying factor structure of the Japanese version of the Posttraumatic Growth Inventory (PTGI-J), a principal components analysis was performed on data from 312 Japanese undergraduate students who reported growth due to their most traumatic event within the last 5 years. Results showed the PTGI-J has high internal consistency and, of the original five factors reported by Tedeschi and Calhoun (1996), three were replicated: Relating to Others, New Possibilities, Personal Strength, and a fourth factor integrating Spiritual Change and Appreciation of Life emerged. There were neither gender differences nor relationships with time since trauma. PTGI-J scores were positively associated with posttraumatic symptoms and correlated with type of traumatic event experienced. These results and future directions are discussed from a cross-cultural viewpoint. 相似文献
