Niveles de procesamiento: Un marco para la investigación sobre la memoria

RESUMEN

Los autores comienzan su trabajo con una exposición de diversos alegatos a favor y en contra de los modelos multialmacén, considerando la validez de las pruebas en que se basan con referencia a los conceptos de capacidad, codificación y características del olvido, centrándose respecto a este último en la función de retención. Seguidamente proponen un marco alternativo en términos de niveles de procesamiento, manteniendo que el trazo de la memoria constituye un subproducto del análisis perceptivo y que su persistencia constituye una función positiva de la profundidad con la que se analiza el estímulo. Los autores reexaminan los datos existentes respecto al aprendizaje incidental, atención selectiva y almacén sensorial, distinción almacenamiento a corto/largo plazo, curva de posición serial y efectos de repetición y repaso. El trabajo termina aclarando que el enfoque de los autores no constituye una teoría sino más bien un marco conceptual con arreglo al cual podría proceder la investigación sobre memoria.     

语义表征具身理论:情绪在概念表征中的作用

概念如何被表征是认知科学的热点问题,其中抽象概念如何表征是当前具身认知最具争议性的话题之一。与前期概念隐喻理论(强调意象图式)和知觉符号理论(强调情境内省信息)的观点不同,语义表征具身理论强调情绪经验信息在抽象概念表征和加工中的作用。具体而言,具体概念的表征主要来自感觉运动信息,而抽象概念的表征主要来自情绪经验信息和语言信息。研究证明,抽象概念的高情绪经验信息能够促进词汇的加工,且这一促进作用受词汇情绪效价的调节。未来研究应进一步考虑影响情绪经验信息发挥作用的因素,比如语言信息的丰富性、情绪唤醒或个体的情绪状态等。     

Psychological models in predicting uptake of prenatal screening

Abstract

The purpose of the current study was to determine which psychological models are most useful in predicting uptake of a prenatal screening test, maternal-serum alphafetoprotein screening for spina bifida and Down's syndrome. 1000 women eligible for the test completed standardised self-report questionnaires at two routine clinic visits to an antenatal clinic prior to the time when the test could take place. 902 underwent the screening test; 51 declined the test; and 47 did not undergo the test, giving no reason for this to staff. Knowledge of the test, the subjective expected utility attached to the test, and attitudes to doctors and medicine were all significant predictors of uptake behaviour. Results of a discriminant function analysis demonstrated distinct psychological processes underlying each of these three uptake behaviours, explaining 21% of the variance in uptake of screening. If uptake of screening is examined not as a dichotomous variable but as a group of behaviours, predictive models are identified accordingly. This would lead to rnodels of health-related behaviours as a heterogeneous rather than homogeneous phenomena, predicted and influenced by different causes.     

Knowledge of drug-related health problems among injecting drug users: Implications for the transmission of HIV infection

Abstract

In a project that investigated the HIV-related risk behaviour of injecting drug users, respondents were categorized along dimensions of expertness in HIV/AIDS knowledge and knowledge about drug-related health problems. Knowledge about drug-related health problems was found to be significantly associated with sharing. Better informed respondents were less likely to share injecting equipment and to predict they would share in future. They were more likely to adopt consistent injecting hygiene, seek information about AIDS, and perceive themselves as in control of their lives. No significant relationships were observed between sharing and HIV/AIDS knowledge. The data have relevance for AIDS educational strategies, since knowledge about AIDS and HIV transmission appears to be insufficient to induce behavioural change. Greater emphasis on the health problems that afflict most injectors may be a way of encouraging general harm minimization.     

On the Road to the Unconscious Self: Understanding when People Gain Self‐knowledge of Implicit Disgust Sensitivity from Behavioural Cues

On the basis of an integration of dual‐process models of information processing and the lens model framework of person perception, we conducted two studies to investigate whether self‐perceivers could detect their implicit disposition from video feedback of behavioural cues and whether these cues were used for explicit dispositional inferences under conditions that maximized the presumed self‐perception process. Using an approach that differed from previous research, we used the following: (i) a more detailed and stepwise self‐perception procedure; (ii) a specific explicit measure compared with a global explicit measure; and (iii) disgust sensitivity as a domain with clear, unambiguous cues and an assumed low self‐presentation bias. The results from two studies (N = 117 and N = 130) on disgust sensitivity provide the first evidence for the assumed process with regard to bodily reaction cues but not with regard to facial expression cues. These novel findings suggest that people can get to know their unconscious selves better if supporting conditions are met and the right behavioural cues are attended to. Additional boundary conditions of this self‐perception process were investigated using display rules and need for closure in Study 2. Copyright © 2013 John Wiley & Sons, Ltd.     

Deliberation Versus Intuition: Decomposing the Role of Expertise in Judgment and Decision Making

What produces better judgments: deliberating or relying on intuition? Past research is inconclusive. We focus on the role of expertise to increase understanding of the effects of judgment mode. We propose a framework in which expertise depends on a person's experience with and knowledge about a domain. Individuals who are relatively experienced but have modest knowledge about the subject matter (“intermediates”) are expected to suffer from deliberation and to benefit from a more intuitive approach, because they lack the formal knowledge to understand the reasons underlying their preferences. Individuals who are high (“experts”) or low (“novices”) on both experience and knowledge are expected to do well or poorly, respectively, regardless of decision mode. We tested these predictions in the domain of art. Experiments 1 and 2 showed that intermediates performed better when relying on intuition than after deliberation. Judgments of experts and novices were unaffected. In line with previous research relating processing style to judgment mode, Experiment 3 showed that the effect of processing style (global versus local) on judgment quality is similarly moderated by expertise.

An evaluation of the UK government health education campaign on AIDS

In the absence of an effective treatment for HI V the only means of containing its spread is through changes in behaviour. Health education is a key route for achieving this. To be effective, a health education campaign must result in behaviour change. The United Kingdom Department of Health and Social Security has attempted to address these needs in a recent health education campaign, which took the form of whole page newspaper advertisements in the national press. Groups of higher and lower risk subjects were questioned before and after the campaign. The desire for information was high and the vast majority of respondents named the medical profession as the desired source to turn to. 31.1% of the lower risk group and 50% of the higher risk group noticed and read the campaign. Information scores were slightly increased but the campaign had no effect on adjusting misconceptions and anxiety was not lowered. Attitudes and behaviour were unaltered. These results are discussed in the light of a content analysis of the campaign.     

Psychological and social characteristics of attenders for breast screening

Abstract

Demographic characteristics, health behaviour and knowledge of breast cancer were assessed in 183 women from a regional breast screening unit and compared with those of 182 women from a breast clinic and 41 control subjects. A questionnaire yielded information on (i) demographic characteristics and cancer-related behaviours including breast self-examination (BSE), use of screening and promptness of presentation of breast symptoms in the clinic group, (ii) the extent and effects of knowledge about breast cancer and (iii) the role of Health Belief Model dimensions. Results showed the screening unit attenders to be significantly older and to be significantly more likely to be from higher social classes. Differences between the groups in health beliefs and knowledge did not remain once the effects of age and social class were partialled out. While attitudes towards BSE and its practice related to health beliefs. only a minority of the women indicated that they practised BSE with any regularity. The results suggest that screening is failing to attract a truly representative sample of the community and raise the possibility that this failure is a consequence of sociological as much as psychological factors.     

The utility of socio-demographics,knowledge and health belief model variables in predicting reattendance for mammography screening: A brief report

Abstract

The aims of the present study were to investigate socio-demographic and knowledge variables as predictors of re attendance for mammography screening and to examine the utility of the Health Belief Model (HBM) in predicting reattendance for mammography screening above and beyond socio-demographic and knowledge variables. A total of 88 reattenders and 44 non-reattenders of an Australian breast screening service completed a questionnaire assessing socio-demographics (age, marital status, education, physician recommendation and family history), knowledge and HBM variables. Results showed that reattenders were more likely to be older, married and report physician involvement than non-reattenders. Family history and knowledge did not significantly predict reattendance. Of the HBM variables, perceived benefits was related to reattendance above and beyond socio-demographics. Results support the utility of the HBM as a focus for improving regular attendance for breast screening. It is concluded that non-reattenders should be investigated as a seperate group to women who have never attended for mammography screening.     

How Do We Acquire Moral Knowledge? Is Knowing Our Duty Ever Passive? – Two Questions for Martin Sticker

Martin Sticker's discussion of the common moral agent contains much that I find insightful, true and significant. As a response to his paper, I focus on two important issues that nevertheless separate us: (1) Sticker claims that knowing our duty can be mere passive awareness and that it indeed is passive as awareness of the special status of humanity. I deny that knowing our duty is ever passive. (2) He further claims that the common universalization test is the paradigmatic way active agents acquire moral knowledge. I argue that Sticker appears to construe universalization as a formal test that presupposes no moral knowledge and that so construed the test cannot serve for acquiring moral knowledge.
