Prior research indicates survey procedures that signal significance and individualized mailings have higher response rates. Thus, it was hypothesized that surveys delivered via Priority mail would result in higher return rates than surveys delivered via First-Class. 260 surveys were sent to individuals randomly selected from lists of licensed physical and behavioral healthcare providers in Alaska and New Mexico. Half of the selected individuals were assigned randomly to receive mailings using Priority mail, the other half received First-Class mailings. Return rate was 39% for First-Class and 35% for Priority. Z tests of proportion indicated no statistically significant differences between methods. Given increased costs with no resultant increase in response rate, sending surveys to potential participants via Priority mail does not appear warranted. 相似文献

In four studies, the authors investigated the extent to which expectations for personality traits in age-graded roles correspond to patterns of personality trait change across the life course. In Studies 1 (N = 43) and 2 (N = 126), the authors examined the age-graded roles of high school student, college student, parent, and grandparent and found that expectations for how people behave in these age-graded roles showed strong parallels to the documented pattern of personality trait development and that this pattern of expectations was largely shared by younger and older participants. In Studies 3 (N = 252) and 4 (N = 123), the authors separated age and role information (e.g., marital, parental, and employment status) and found that people use both sources of information independently in forming expectations of others. The implications for understanding the interplay of expectations and personality trait development are discussed. 相似文献

Individual differences in sentence memory 总被引:1,自引:0,他引:1
Results from an experiment with two parts are presented in this paper. In part one, participants listened to sentences containing two, three, four, or five clauses, and were asked questions about the content of the sentences. The results of part one demonstrate that an important unit of representation in sentence memory is the clause, and not some other component of discourse structure. In part two, the same group of participants performed eight different short-term storage/working memory tasks. A composite complex span score was computed for each participant based on three working memory tasks closely based on Daneman & Carpenter's (1980) reading span task. This working memory measure was significantly correlated with the participants' performance on the sentence memory task in part one. A second working memory measure—N-back—was also significantly correlated with the participants' performance on the sentence memory task, and there was no correlation between their performance on the complex span task and the N-back task. It is therefore concluded that (i) working memory consists of a number of dissociable components; and (ii) memory for sentences taps into more than one of these working memory components. Furthermore, the high correlations of sentence memory with the complex span and the N-back tasks (neither of which are language processing tasks) suggests that memory for sentences is not simply a result of linguistic experience; rather, it is likely that an independent working memory component contributes to participants' performance on the sentence memory task. 相似文献

Participants viewed a videotape of a simulated murder, and their recall (and confidence) was tested 1 week later with the cognitive interview. Results indicated that (a) the subset of statements assigned high confidence was more accurate than the full set of statements; (b) the accuracy benefit was limited to information that forensic experts considered relevant to an investigation, whereas peripheral information showed the opposite pattern; (c) the confidence-accuracy relationship was higher for relevant than for peripheral information; (d) the focused-retrieval phase was associated with a greater proportion of peripheral and a lesser proportion of relevant information than the other phases; and (e) only about 50% of the relevant information was elicited, and most of this was elicited in Phase 1. 相似文献

Participants at a June 2002 conference about the September 11th attacks were tested for compassion fatigue, compassion satisfaction, and burnout. The sample consisted of 343 clergy, including 97 chaplains. A total of 149 (43.4%) of the participants had responded as disaster-relief workers following the September 11th attacks. The number of hours clergy worked with trauma victims each week was directly related to compassion fatigue among responders and non-responders. Compassion fatigue also was positively related to the number of days that responders worked at Ground Zero, while disaster-relief work with the American Red Cross reduced compassion fatigue and burnout. Clinical Pastoral Education tended to decrease compassion fatigue and burnout and increase compassion satisfaction in both responders and non-responders. Burnout was inversely related to age in both groups. 相似文献

Syllogistic reasoning, in which people identify conclusions from quantified premise pairs, remains a benchmark task whose
patterns of data must be accounted for by general theories of deductive reasoning. However, psychologists have confined themselves
to administering only the 64 premise pairs historically identified by Aristotle. By utilizing all combinations of negations,
the present article identifies an expanded set of 576 premise pairs and gives the valid conclusions that they support. Many
of these have interesting properties, and the identification of predictions and their verification will be an important next
step for all proponents of such theories. 相似文献

Right hemisphere damaged patients with and without left visual neglect, and age-matched controls had objects of various sizes presented within left or right body hemispace. Subjects were asked to estimate the objects' sizes or to reach out and grasp them, in order to assess visual size processing in perceptual-experiential and action-based contexts respectively. No impairments of size processing were detected in the prehension performance of the neglect patients but a generalised slowing of movement was observed, associated with an extended deceleration phase. Additionally both patient groups reached maximum grip aperture relatively later in the movement than did controls. For the estimation task it was predicted that the left visual neglect group would systematically underestimate the sizes of objects presented within left hemispace but no such abnormalities were observed. Possible reasons for this unexpected null finding are discussed. 相似文献

Observing structured parent-child interaction in clinic analogs has been a tradition in child clinical assessment since the 1960s. The clinic analog is designed to re-create important conditions from natural contexts such that dysfunctional parent-child patterns can be observed and modified. To those basic goals, the modern clinician would add diagnosis and treatment evaluation. Three classes of parent-child clinic analogs designed to evaluate preadolescent children with externalizing disorders were reviewed: free play, parent-directed play, and parent-directed chores. Free-play analogs and parent-directed chore analogs were found to have merit, but remain psychometrically underdeveloped. Practitioner reliance on questionnaires and interviews appears likely to continue until observational analogs have attained sufficient psychometric qualities to facilitate routine clinical decisions. 相似文献

In this paper we review three prospective longitudinal studies from our laboratory examining the effects of prenatal stress on early neuro behavior, stress reactivity and learning performance in rhesus monkeys. Either a noise stressor or ACTH treatment was administered to pregnant monkeys during specific periods of pregnancy and offspring were examined repeatedly across development. In all three studies, the prenatally stressed monkeys showed reduced attention and impaired neuromotor functioning during the first month of life compared to controls from undisturbed pregnancies. When the monkeys were separated from their mothers or peers at 6-8 months of age, prenatally stressed monkeys exhibited more disturbance behavior and showed hypothalamic-pituitary-adrenal axis dysregulation. During adolescence, they exhibited impairments in learning, compared to controls. 相似文献

Two rat experiments shed light on how variation in behavior is regulated. Experiment 1 used the peak procedure. On most trials, the 1st bar press more than 40 s after signal onset ended the signal and produced food. Other trials lasted much longer and ended without food. On those trials, the variability of bar-press duration increased greatly after the 1st response more than 40 s after signal onset. In Experiment 2, which asked whether the increase was due to the omission of expected reward or the decrease in reward expectation, reward expectation had a strong effect on response duration, whereas omission of expected reward had little effect. In both experiments, response rate and response duration changed independently, suggesting that they reflect different parts of the underlying mechanism. In Experiment 1, response durations implied that timing of the signal was more accurate than the rate-vs.-time function might suggest. Experiment 2 suggested that lowering reward expectation increases variation in response form. 相似文献
