The Wisconsin Inventory of Smoking Dependence Motives (WISDM) assesses 13 theoretically-derived dimensions of smoking motivation. These 13 subscales were intended to index comprehensively the severity of tobacco dependence and provide insight into the disorder. Recent studies indicate that four subscales (Automaticity, Craving, Loss of Control, and Tolerance) represent the core features of tobacco dependence and have been dubbed the Primary Dependence Motives (PDM). The remaining nine subscales, the Secondary Dependence Motives (SDM), may be clinically relevant but index less essential features of dependence. 相似文献

Sleep onset is associated with marked changes in behavioral, physiological, and subjective phenomena. In daily life though subjective experience is the main criterion in terms of which we identify it. But very few studies have focused on these experiences. This study seeks to identify the subjective variables that reflect sleep onset. Twenty young subjects took an afternoon nap in the laboratory while polysomnographic recordings were made. They were awakened four times in order to assess subjective experiences that correlate with the (1) appearance of slow eye movement, (2) initiation of stage 1 sleep, (3) initiation of stage 2 sleep, and (4) 5 min after the start of stage 2 sleep. A logistic regression identified control over and logic of thought as the two variables that predict the perception of having fallen asleep. For sleep perception, these two variables accurately classified 91.7% of the cases; for the waking state, 84.1%. 相似文献

If working memory (WM) depends on a central resource—as is posited in some theories, but not in others—it should be possible
to observe interference between tasks that share few features with each other. We investigated whether interference with WM
for visual arrays would occur, even if the interfering task required neither visual processing nor overt responding. In an
auditory-verbal interfering task, a response was to be made if a word was recognized as having come from one of two prelearned
lists, but not from the other list. As compared with nonretrieval control conditions, even covert verbal memory retrieval
disrupted the storage of visual items held in WM. A second experiment ruled out verbal recoding of the visual arrays as the
basis of interference. The results indicate that visual WM and verbal long-term retrieval share a central resource (e.g.,
attention). 相似文献

To increase understanding of how Master of Divinity education actually functions and to respond to accreditors' emphasis on the outcomes of learning, this paper presents a research‐based model that focuses on how M.Div. education transforms students. The students‐in‐seminary model is conceptually undergirded by life course theory. In the model, students attending seminary engage in a messy process in which they respond to competing demands of school, church, and family. The author compares the students‐in‐seminary model with the dominant message model for theological education articulated by Carroll et al. (1997 ) and argues that the students‐in‐seminary model more adequately describes the process of theological education. The author calls for further research to study how seminaries promote key messages to their students, the plasticity of students' sense of calling, the impact of church requirements on M.Div. students, and the complexity of life for multiple‐role students. 相似文献

This study assessed differences in response rates to a mailed health survey by adults in two neighboring rural midwestern counties with differential incentives, of dollar 2.00 and dollar 5.00. Potential respondents in each county were randomly selected from a commercial database of residents' addresses. County "F" respondents (n = 541) which were 57% female and 95% Euro-American having a mean age of 47.3 yr. (SD= 16.9), received the dollar 5 incentive. County "H" respondents (n= 514) were 63% female, 95% Euro-American, had a mean age of 49.0 yr. (SD= 14.7), and received a S2 incentive. The response rates were 71% using the dollar 2 incentive and 73% using the dollar 5 incentive. These were not significantly different by chi-square test. The more cost-effective incentive for increasing the response rate of adults in this rural midwestern sample was to code the envelopes and use a dollar 2.00 rather than dollar 5.00 incentive, a cost per returned survey of dollar 5.24 versus dollar 9.13, respectively. The findings support Dillman's principle of diminishing returns as the size of the incentive goes up. 相似文献

RESISTANCE TO CHANGE AND FREQUENCY OF RESPONSE‐DEPENDENT STIMULI UNCORRELATED WITH REINFORCEMENT 下载免费PDF全文

Stimuli uncorrelated with reinforcement have been shown to enhance response rates and resistance to disruption; however, the effects of different rates of stimulus presentations have not been assessed. In two experiments, we assessed the effects of adding different rates of response‐dependent brief stimuli uncorrelated with primary reinforcement on relative response rates and resistance to change. In both experiments, pigeons responded on variable‐interval 60‐s schedules of food reinforcement in two components of a multiple schedule, and brief response‐dependent keylight‐color changes were added to one or both components. Although relative response rates were not systematically affected in either experiment, relative resistance to presession feeding and extinction were. In Experiment 1, adding stimuli on a variable‐interval schedule to one component of a multiple schedule either at a low rate (1 per min) for one group or at a high rate (4 per min) for another group similarly increased resistance to disruption in the components with added stimuli. When high and low rates of stimuli were presented across components (i.e., within subjects) in Experiment 2, however, relative resistance to disruption was greater in the component presenting stimuli at a lower rate. These results suggest that stimuli uncorrelated with food reinforcement do not strengthen responding in the same way as primary reinforcers. 相似文献

The authors extended previous work on the hypothesis that borderline personality disorder (BPD) can be understood as a maladaptive variant of personality traits included within the 5-factor model (FFM) of personality. In each of 3 samples, an empirically derived prototypic FFM borderline profile was correlated with individuals' FFM profiles to yield a similarity score, an FFM borderline index. Results across all samples indicated that the FFM borderline index correlated as highly with existing borderline measures as they correlated with one another, and the FFM borderline index correlated as highly with measures of dysfunction, history of childhood abuse, and parental psychopathology as did traditional measures of BPD. Findings support the hypothesis that BPD is a maladaptive variant of FFM personality traits. 相似文献

The Fading Affect Bias (FAB) occurs when the affect associated with personal events fades differentially across time: Positive affect fades slower than negative affect. Three studies examined whether the magnitude of the FAB is moderated by narcissism. Results from Study 1 (diary method, N = 26) showed that low narcissism participants evidenced a large FAB, but high narcissism participants evidenced a reversed FAB. Results from Study 2 (retrospective recall method, N = 110) showed that low narcissism participants evinced a large FAB and that the FAB diminished or dissipated as narcissism increased. Results from Study 3 (retrospective recall method, N = 83) showed that high narcissists evinced a FAB when they recalled achievement‐themed autobiographical events but evinced a reversed FAB when they recalled communal‐themed events. These findings occurred independently of event rehearsal frequency. Results are discussed in terms of the idea that emotion regulation efforts may be disrupted in narcissists.
