Highly creative advertisements are the end-products of creativity in advertising, and their creation is generally thought to be driven by strategic planning. Thus, 534 Clio-awarded advertisements from the years 2011–2014 were content-analyzed to determine whether implications of two popular planning frameworks, functional matching and the Foote, Cone, and Belding Planning Model, were present in the industry’s best creative work. Since 1960, the Clio Award Program has annually recognized the world’s most creative advertisements. Clio-awarded advertisements are selected by panels of advertising experts specifically constituted to offset gender and country of origin bias. The study found that implications of the two planning frameworks were not present in the industry’s most creative work: types of value-expressive appeals were more frequent than types of utilitarian appeals in Clio-awarded advertisements, regardless of the nature of the advertised products or the category of media used to deliver product messaging. These findings support previous research, which found that highly creative advertising rarely is based on strategic considerations. However, they were inconsistent with other research regarding the presence of the two planning frameworks in general TV advertising. 相似文献

The present study examined the impact of asthma-specific thought intrusion (TI) and thought suppression (TS) on two cognitive-affective variables (self-focused attention and fear of negative evaluation) among adolescents and young adults (AYAs) diagnosed with childhood-onset asthma. Participants were 290 AYAs who completed assessment questionnaires and participated in a written exercise electronically. Asthma-TI and TS were reported by participants following participation in a writing assignment. Asthma-TI was associated with increased private, public, and social anxiety self-focused attention, and greater fear of negative evaluation. Interestingly, asthma-TS was not associated with these same outcome variables. Findings suggest illness-specific cognitions are associated with cognitive-affective variables and it may be important to assess for illness-specific intrusive thoughts following asthma-focused medical appointments. Additionally, findings suggest the importance of assessing asthma-TI and TS separately in order to better understand thoughts about health and psychological functioning. 相似文献

A naturalistic study of spatial memory having temporary utility was conducted using 32 faculty and staff of a university, who park in non-reserved parking spaces, as subjects. The subjects, who were unaware of the study until interviewed, were asked to indicate on a map the exact location where they had parked their car on that day and on each of the three preceding days. Whereas retention accuracy decreased significantly across days, the recency effect was weak and overall retention proved to be very accurate. Of the subjects who varied their parking location, 88 per cent were able to indicate within three spaces where they parked on the day of the interview, and 58 per cent on the most remote day. Younger females made significantly larger retention errors across the four days than older females and younger and older males. Subjects' overall retention accuracy correlated with their overall confidence in their recollections (γ = .72). Daily ratings of ‘how busy on the job’, reported times left campus each day, parking location variability, particular parking lot used, and number of parking spaces in the distinct locations used were not significantly correlated with retention errors. In follow-up interviews, subjects reported preferring a behavioural, ‘park in a favourite spot’ strategy, with several types of imagery-based cognitive strategies being cited less frequently, and verbal encoding being the least often cited strategy. 相似文献

Developmental norms for young children’s vocabularies have a number of applications in research design, assessment, and intervention, but have previously been very difficult to obtain. In the present study, month-by-month norms for comprehension and production of 396 words from 8 to 16 months, and production of 680 words from 16 to 30 months, were derived from a norming study of 1,789 children between the ages of 8 and 30 months using the MacArthur Communicative Development Inventories (Fenson et al., 1993). The norms are available in the form of a database program, LEX, for MS-DOS-based computers. 相似文献

The present study examined the effects of sexual orientation matching and supervisory role on supervisory style and satisfaction with homonegativism as a covariate. Supervisory style significantly correlated with satisfaction for supervisors when trainees were heterosexual but not when trainees were lesbian, gay, or bisexual. Regardless of supervisor or trainee sexual orientation, the supervisors’ homonegativism significantly negatively correlated with trainees’ satisfaction and ratings of supervisors’ style. No significant differences in supervisory style were found among supervision dyads cross-matched for sexual orientation while controlling for homonegativism. 相似文献

Attempts to devise verbal and non-verbal instruments for measuring pictorial depth perception that are different from Hudson's (1960) have resulted in different perceptual demands. Whereas this was recognized by the constructors of non-verbal tests, it was not by those who changed Hudson's question “Which is nearer to the man…?” to “Which is/looks nearer/farther to you… ?”. While the latter question tests simple perception (or interpretation of cues) of pictorial depth, the former tests comprehension of complex pictorial space relations arising from the depth perceived. A verbal instrument that had been devised for testing simple pictorial depth interpretation, equivalent to Jahoda and McGurk's (1974) non-verbal instrument, was tested on Grade 3 Shona children against the hypothesis that the terms “nearer” and “farther” have different lexical markings likely to affect subject's responses. No support was found for the hypothesis, but Opolot's (1976) Grade 3 findings were able to be explained. 相似文献

After a single presentation of a word list, normal subjects exhibited better retention when prompted with semantic cues than with rhyme or letter cues. Alcoholic Korsakoff patients, patients receiving electroconvulsive therapy (ECT), and the patient N.A. exhibited impaired retention and, unlike control subjects, did not exhibit an advantage of semantic cues over letter and rhyme cues. Two experimental manipulations designed to equate the level of performance of amnesics and controls indicated that these amnesias could be understood as a reflection of weak memory strength that results from deficiencies in initial learning and retention. In addition, alcoholic Korsakoff patients appeared to have greater difficulty utilizing semantic cues than patients receiving ECT or patient N.A. 相似文献

Reversible hippocampal lesions disrupt water maze performance during both recent and remote memory tests 总被引:6,自引:0,他引:6 下载免费PDF全文
Conventional lesion methods have shown that damage to the rodent hippocampus can impair previously acquired spatial memory in tasks such as the water maze. In contrast, work with reversible lesion methods using a different spatial task has found remote memory to be spared. To determine whether the finding of spared remote spatial memory depends on the lesion method, we reversibly inactivated the hippocampus with lidocaine either immediately (0-DAY) or 1 mo (30-DAY) after training in a water maze. For both the 0-DAY and 30-DAY retention tests, rats that received lidocaine infusions exhibited impaired performance. In addition, when the 0-DAY group was retested 2 d later, (when the drug was no longer active), the effect was reversed. That is, rats that had previously received lidocaine performed as well as control rats did. These findings indicate that the rodent hippocampus is important for both recent and remote spatial memory, as assessed in the water maze. What determines whether remote spatial memory is preserved or impaired following disruption of hippocampal function appears to be the type of task used to assess spatial memory, not the method used to disrupt the hippocampus. 相似文献

Social risk and protective factors for suicide attempts in low income African American men and women 总被引:2,自引:0,他引:2

A case-control study was conducted to examine a broad array of potential social risk and protective factors for suicide attempt among 200 African American men and women receiving care at a large, public, urban hospital. Specifically, we examined the effect of the following potential risk factors for suicide attempt: life hassles, partner abuse, partner dissatisfaction, and racist events; as well as the following potential protective factors: effectiveness of obtaining resources, social embeddedness, and social support. Using logistic regression, suicide attempter status was predicted by two independently significant social variables: one risk factor (life hassles) and one protective factor (social support). Male versus female suicide attempters were not distinguished by the social variables. These findings, which support the utility of an ecological conceptualization of risk and protective factors for suicide attempt, help to clarify the independently significant social environment risk and protective factors for suicide attempts among economically disadvantaged African Americans in particular. Research on both risk factors and protective factors provide a basis for culturally competent interventions aimed at reducing both the risk of future suicide attempts and completions. 相似文献

Calculation of the statistical power of statistical tests is important in planning and interpreting the results of research studies, including meta-analyses. It is particularly important in moderator analyses in meta-analysis, which are often used as sensitivity analyses to rule out moderator effects but also may have low statistical power. This article describes how to compute statistical power of both fixed- and mixed-effects moderator tests in meta-analysis that are analogous to the analysis of variance and multiple regression analysis for effect sizes. It also shows how to compute power of tests for goodness of fit associated with these models. Examples from a published meta-analysis demonstrate that power of moderator tests and goodness-of-fit tests is not always high. 相似文献
