Although previous research indicates that certain types of attention (i.e., statements related to behavior, tickles) may be differentially reinforcing, only one or two forms of attention are typically provided contingent on problem behavior during the attention condition in experimental functional analyses. In the present investigation, various forms of attention were provided contingent on problem behavior to identify the influence of each form of attention. Results indicated that the attention forms affected problem behavior differently; these outcomes are discussed in terms of their implications for assessment and treatment. 相似文献

Four pigeons were first trained in a timing procedure. In one condition, each trial began with the presentation of an X on the center key, followed by a delay (short or long), after which two side keys were lit. If the delay was short, pecks to the red side key were reinforced. If the delay was long, pecks to the green side key were reinforced. In a second condition, the opposite contingencies applied following presentation of a square on the center key. Choice responses were then tested at 10 time intervals ranging from short to long (1 to 4 s and 4 to 7 s in different conditions). The two timing conditions were combined to create a remembering condition in which correct responding depended upon discrimination of both the sample stimulus (X or square) and the delay interval (short or long). Choices varied systematically across delay in timing conditions, but in remembering conditions, accurate choice at the training delays did not initially generalize to intermediate delays. However, with prolonged training in the remembering task, the response pattern began to resemble that of the timing conditions. Generalization gradients were asymmetrical, in accordance with Weber's Law, in that greater generalization occurred with longer delays than with shorter delays. 相似文献

Attachment scores for 658 young adults living in the U.S.A. were obtained using the Experiences in Close Relationships scale. The participants came from a subsample of the RELATE data set, who had also filled out the adult attachment measure. Those young adults living in Utah County, Utah, an area of the country with a higher than normal birthrate (88% members of the Church of Jesus Christ of Latter-day Saints), also had higher than average adult attachment scores. While the methodology was not sufficient to assess causal direction nor eliminate the possibility of unidentified influences, an undiscussed psychological factor, adult attachment, may play a role in the numerical declines observed among nonimmigrant communities in the USA and Europe. 相似文献

This welcomes Equality: From Theory to Action as an important contribution both to linking egalitarian political philosophy to public policy and as a book which helps
communicate a wealth of philosophical ideas in an accessible way to a wide public. On the critical side, it argues that the
authors understate some tensions between egalitarianism and pluralism, and that the book’s discussion of egalitarian economic
institutions is quite narrow in scope. As a complement and development of this latter discussion, the paper discusses some
policy proposals to address inequality of wealth. 相似文献

Latencies (RT) and eye movement measures were used to examine the effects of age and contrast on the distractor-ratio effect (DRE) in visual search. Younger and older adults performed a contrast x orientation conjunction search task where the ratios of white to black distractors and luminance contrast levels were varied. The distractor-ratio manipulation had similar effects for older and younger adults on both RT and the number of fixations required to find the target. Both measures were largely independent of distractor ratio on target-present trials, while both RTs and the fixation number increased with the number of items sharing the target's contrast polarity on target-absent trials. A more detailed analysis of eye movements suggested that younger adults were a bit more adept at attending to the smaller set of distractors, which presumably facilitated both overt and covert search. Generalized slowing can account for the age differences in RT, but the fixation number data speak to another mechanism, perhaps increased cautiousness on the part of the elderly when signal strength is low. 相似文献

Residents (N = 142) of a southeastern, upscale retirement community completed measures of wellness, perceived stress, and mattering. Participants scored higher than did a group of adults under age 60 on 4 of 5 second‐order wellness factors and Total Wellness, with medium to large effect sizes. Implications for counselors are discussed. 相似文献

People with scleroderma often experience disfiguring appearance-related changes in socially visible and interpersonally salient areas. Although disfigurement can lead to body image dissatisfaction, this phenomenon has not been well investigated due to the lack of a disfigurement-specific measure. The Satisfaction With Appearance (SWAP) scale, previously developed in burn survivors, was adapted and administered to 254 participants with scleroderma to evaluate its psychometric integrity and its validity for use in a different medical population that experiences changes in appearance. Principal component analysis revealed two factors – Subjective Dissatisfaction and Perceived Social Impact – rather than the four found in burn victims. Excellent estimates of internal consistency and temporal stability and strong evidence for the reliability of the two-factor solution were found. The resulting factor structure in a scleroderma population suggests that differing medical conditions may create alternate constellations of BID, reflects the need for body image researchers to assess psychometrics across medical populations and may have clinical implications for BID interventions. 相似文献

ABSTRACT— The debate surrounding the use of subjective measures of well-being for policy purposes has intensified in recent years. Many social scientists are arguing that the time is right for policymakers to extend their traditional focus on material well-being and economic development to include the impact policies have on how people think and feel about their lives. However, policymakers may have many legitimate goals beyond making people happy. In this article, we begin by presenting three archetypal accounts of well-being that policymakers could use to guide policy (mental-state, objective-list, and desire-fulfillment accounts) and discussing some of the normative and methodological limitations of each. We discuss how a subjective (mental-state) approach could be used to aid the achievement of objective-list and desire-fulfillment policy goals. We then consider ways in which a subjective approach may benefit policymakers in its own right, such as by aiding the valuation of hard-to-quantify costs and benefits, providing a standard unit of measurement for comparisons of well-being across domains, and helping to set policy defaults. We conclude with a discussion of some of the remaining measurement issues and general policy implications. 相似文献
