Negative anticipatory contrast and preference conditioning: flavor cues support preference conditioning, and environmental cues support contrast.

In 2 experiments, access to a 0.15% saccharin solution was followed on alternating days by access to a 32% sucrose solution and the same saccharin solution. In Experiment 1, rats increased both intake of and preference for a flavored saccharin solution that predicted sucrose, but neither effect was found using a predictive odor cue alone. Experiment 2 replicated the predictive flavor results but showed suppression of saccharin intake when environmental cues predicted sucrose. When both flavor and environment predicted sucrose, saccharin intake did not change, but preference for the predictive flavor increased. Discriminative taste cues appear to facilitate the development of preference conditioning, but environmental cues favor negative anticipatory contrast effects. Also, preference conditioning and contrast may develop concurrently and compete for expression.     

Context effects in lexical access: A meta-analysis

The modularity hypothesis was evaluated in this review of 25 studies that investigated context effects in early lexical processing. Selection criteria restricted the review to priming studies and to studies that presented the target word before or at the end of the prime word. Meta-analysis was used to provide summary information about the 17 studies in the review for which effect sizes could be calculated. Overall, the analysis revealed a small effect of context on lexical access. Results provide a disconfirmation of the modularity hypothesis; although multiple interpretations of a word were sometimes accessed, the contextually appropriate interpretation was consistently more strongly activated. The lack of significant heterogeneity of variance suggests that the variability observed across studies was due to sampling error; however, task, timing of target presentation, meaning frequency, type of target, and type of context were identified as potential moderator variables.     

Features of Interview Questions Associated with Attenuation of Symptom Reports

Previous studies have suggested that discrepant reporting in a test–retest reliability paradigm is not purely random measurement error, but partly a function of a systematic tendency to say no during retest to questions answered positively at initial testing (attenuation). To examine features of interview questions that may be associated with attenuation, three raters independently assessed the structural and content features of questions from the Diagnostic Interview Schedule for Children (version 2.3) and linked these to data from a test–retest reliability study of 223 community respondents (parent and child reports). Results indicated that for both parent and youth reports, item features most strongly associated with attenuation were (a) being a stem question (asked of all respondents, regardless of any skip structure); (b) question placement in the first half of the interview; (c) question length; (d) question complexity; or (e) requiring assessment of the timing, duration, or frequency of a symptom. Findings may be explained by participants' conscious efforts to avoid further questions or by their learning more about the nature and purpose of the interview as they gain more experience; alternatively, findings may represent a methodological artifact of structured interview design.     

Privacy and the Computer: Why We Need Privacy in the Information Society

For more than thirty years an extensive and significant philosophical debate about the notion of privacy has been going on. Therefore it seems puzzling that most current authors on information technology and privacy assume that all individuals intuitively know why privacy is important. This assumption allows privacy to be seen as a liberal "nice to have" value: something that can easily be discarded in the face of other really important matters like national security, the doing of justice and the effective administration of the state and the corporation. In this paper I want to argue that there is something fundamental in the notion of privacy and that due to the profoundness of the notion it merits extraordinary measures of protection and overt support. I will also argue that the notion of transparency (as advocated by Wasserstrom) is a useless concept without privacy and that accountability and transparency can only be meaningful if encapsulated in the context of privacy. From philosophical and legal literature I will discuss and argue the value of privacy as the essential context and foundation of human autonomy in social relationships. In the conclusion of the paper I will discuss implications of this notion of privacy for the information society in general, and for the discipline of information systems in particular.     

The role of recall time in producing hypermnesia

In two experiments subjects presented with either words or pictures showed improved recall over three successive recall tests for both types of materials, partially replicating Erdelyi’s finding of hypermnesia. However, these subjects did not recall more unique items than other subjects who received only one test equated in time with the three shorter ones. It is concluded that hypermnesia results from simply allowing subjects additional recall time. In a third experiment subjects were shown to recall additional information even after a long recall period employed during an experimental session. This surprising amount of item recovery during long recall periods is attributed to the use of subjective retrieval cues that are thought to function in a manner analogous to externally manipulated cues.     

Engagement with beauty: appreciating natural, artistic, and moral beauty

The Engagement With Beauty Scale (EBS), designed from the aesthetics of I. Kant (1790/1987), G. W. F. Hegel (ca. 1835/1993), and T. Aquinas (ca. 1260/1947) and the psychological work of J. Haidt (J. Haidt & D. Keltner, 2004), measures engagement with natural, artistic, and moral beauty. In Studies 1 and 2, the authors describe scale construction, exploratory factor analysis, confirmatory factor analysis, internal consistency, and temporal stability. In Studies 1 and 2, the authors also establish concurrent validity with the Appreciation of Beauty and Excellence subscale of the Values in Action Inventory of Strengths (C. Peterson & M. E. P. Seligman, 2004), the Gratitude, Resentment, and Appreciation Test (P. C. Watkins, K. Woodward, T. Stone, & R. L. Kolts, 2003), and the Spiritual Transcendence Scale (R. L. Piedmont, 2004). In Study 3, the authors used the EBS Artistic Beauty subscale to differentiate students engaged in the arts from those who were not.     

Explaining the extraversion/positive affect relation: sociability cannot account for extraverts' greater happiness

The association between Extraversion and positive affect is one of the most robust findings in the study of personality and emotion. Temperament models posit that the association is direct; instrumental models posit that the association is mediated by additional processes. Two experience sampling studies were conducted to test instrumental mechanisms that might underlie the effect. According to a mediation model, extraverts' greater social activity can account for their increased positive affect when compared to introverts. According to a person-by-situation interaction model, extraverts react more positively to social situations than do introverts, and this interaction can account for the association. Only weak support for the instrumental models was found; consistent with temperament models, a moderate direct association remained even after controlling for these effects.     

Benefits of Accounts of Well-Being— For Societies and for Psychological Science

The decisions of business leaders and government officials are currently guided by economic and social indicators. It is proposed that accounts of well-being be collected on an ongoing basis to complement the existing indicators. Accounts of subjective well-being would track the societal groups where happiness, life satisfaction, engagement, and positive feelings are high versus low, would indicate the activities that people find enjoyable versus unpleasant, and would monitor changing levels of well-being over time. The accounts would serve decision-makers by making important information on well-being and ill-being available to them. They would also greatly help applied psychology by drawing more attention and interest to important outcomes that are likely to result from psychological interventions.
Les décisions des chefs d'entreprise et des responsables gouvernementaux se fondent actuellement sur des indicateurs sociaux et économiques. On propose de recueillir des données relatives au bien-être de façon continue en complément des indicateurs existants. Les mesures du bien-être subjectif détecteraient les groupes sociaux où le bonheur, la satisfaction de vivre, le sens des responsabilités et les sentiments positifs sont élevés ou bas, indiqueraient les activités que les gens trouvent agréables ou non et suivraient avec le temps les changements dans le niveau du bien-être. Ces mesures seraient utiles aux décisionnaires en mettant à leur disposition des informations importantes sur le bien-être et son contraire. Elles seraient aussi d'un grand secours pour la psychologie appliquée en accordant davantage d'attention et d'intérêt aux conséquences importantes susceptibles de résulter des interventions psychologiques.
