Understanding the Complexity of Everyday Interethnic Contact: Recommendations for Researchers

Interethnic contact has long been a focus of social psychological research, and in this article, we provide some recommendations about how to study interethnic social contact. Our primary recommendation is that researchers should study interethnic contact more in vivo to complement single assessment surveys and laboratory research, sometimes of arbitrarily defined groups, with more naturalistic research and with research involving groups that exist in the real world. This recommendation is based in part on the limitations of surveys and laboratory methods and in part on the advantages provided by what are referred to as intensive repeated measures designs, methods that have proven to be useful in studying other topics. We discuss these limitations and the relative advantages of different types of intensive repeated measures methods for the study of interethnic contact and provide some recommendations for their use. Finally, regardless of how they study interethnic contact, researchers need to expand the focus of their questions, increase the sensitivity of the data they collect, and increase the ethnic diversity of the samples they study.     

Experimental setting affects the performance of guppies in a numerical discrimination task

A recent study found that guppies (Poecilia reticulata) can be trained to discriminate 4 versus 5 objects, a numerical discrimination typically achieved only by some mammals and birds. In that study, guppies were required to discriminate between two patches of small objects on the bottom of the tank that they could remove to find a food reward. It is not clear whether this species possesses exceptional numerical accuracy compared with the other ectothermic vertebrates or whether its remarkable performance was due to a specific predisposition to discriminate between differences in the quality of patches while foraging. To disentangle these possibilities, we trained guppies to the same numerical discriminations with a more conventional two-choice discrimination task. Stimuli were sets of dots presented on a computer screen, and the subjects received a food reward upon approaching the set with the larger numerosity. Though the cognitive problem was identical in the two experiments, the change in the experimental setting led to a much poorer performance as most fish failed even the 2 versus 3 discrimination. In four additional experiments, we varied the duration of the decision time, the type of stimuli, the length of training, and whether correction was allowed in order to identify the factors responsible for the difference. None of these parameters succeeded in increasing the performance to the level of the previous study, although the group trained with three-dimensional stimuli learned the easiest numerical task. We suggest that the different results with the two experimental settings might be due to constraints on learning and that guppies might be prepared to accurately estimate patch quality during foraging but not to learn an abstract stimulus–reward association.     

The Origins of the Anaphoral Benedictus

This paper presents evidence for the Benedictus following theSanctus having been introduced first in Jerusalem in the Liturgyof St James. The structure and variety of the Benedictus areexamined, along with theories of Jewish and Antiochene originin relation to the Apostolic Constitutions. A fifth-centuryJerusalem homily provides the first evidence for the Mattheanform, subsequently contained in all versions of the Liturgyof St James and which becomes normative for nearly all eucharistictraditions. The conclusion distinguishes between the originsof the idea of the anaphoral Benedictus and the origins of itsform. The idea of a ‘blessed be’ acclamation afterthe Sanctus may well lie in Jewish traditions, but the originsof its form lie in the Palm Sunday acclamation of fourth-centuryJerusalem.     

Not all positive categories are alike: Exploring the superiority of the self as a positive source for associative attitude change via intersecting regularities

In associative evaluative learning, attitudes can originate from intersecting regularities between a target and both positive- and self-related stimuli. Liking for a focal target is primarily driven by its reference to one source, but it might be qualified by the reference to a contrast target. This contribution focuses on how the nature of positive and contrast sources affects learning via intersecting regularities. In two studies (N = 199 and N = 185), the self and another positive category lead to increased implicit and explicit liking, regardless of the contrast source's valence. In Study 3 (N = 128), confronting the self and the positive category in the same paradigm yields only implicit preferences for self-related targets. Both implicitly and explicitly, this preference for self- over positive-related target was moderated by self-positivity. Our findings confirm the robustness of learning via intersecting regularities and suggest that the self is a special evaluative source.

The IAT as a predictor of food choice: The case of fruits versus snacks

One of the issues concerning the application of implicit measures like the IAT is whether they can be successfully applied to consumer choices. The empirical evidence of the predictive validity of the IAT so far has been mixed, both at the level of eating habits and of specific behavioural food choices. Moreover, whereas the predictive validity of the IAT has been tested in a number of studies, its incremental validity has not been studied as thoroughly. In this contribution, four studies, run at different points in time and analysed as a single sample (N = 399), tested the predictive and incremental validity of an IAT of attitudes towards fruits versus snacks on the choice of a fruit or a snack at the end of the experimental session. Specifically, an additive pattern in which both implicit and explicit measures predict independently, and an interactive one in which implicit and explicit measures predict interactively, were tested for the prediction of the behavioural preference towards snacks or fruits. The results showed that the IAT has both predictive and incremental validity, over and above the significant prediction provided by explicit measures for behavioural food choice. Furthermore, no interaction effect between implicit and explicit measures in the behavioural prediction was obtained, supporting the additive rather than the interactive pattern. Finally, only the explicit attitude towards snacks predicted behavioural choice whereas the explicit attitude towards fruits did not. This result indirectly suggests that a single target IAT might be fruitfully adopted in future research.     

The formal pace of Sesame Street over 26 years

Television producers often use a high rate in the succession of visual and auditory features in their programs to attract the attention of viewers. In this study an attempt was made to measure the formal pace of television programs by scoring the rates of an extensive set of formal visual and auditory characteristics. Sesame Street was chosen as a focal point because this educational program--with its high pace--is very successful in its competition with the majority of commercial programs from which children can choose to watch at home. The analyzed material consisted of 49 Dutch episodes of Sesame Street broadcast between 1977 and 2003. The formal pace characteristics of separate program items from Sesame Street could be reliably established. Factor analysis indicated that clear pace factors were (a) "editing," consisting of a frequent use of different types of shots (total shots, medium shots, and close-ups) combined with a large number of cuts and (b) speech rate. Over a period of 26 years, the pace of editing increased: the mean number of cuts increased from about 4 to 8 per minute. The mean speech rate decreased from 175 to 139 words per minute.     

How to launch a national Internet-based panel study quickly: lessons from studying how American are coping with the tragedy of September 11, 2001?

This article reports on the planning, development, and implementation of a large national Internet-based panel study of how Americans are coping with the terrorist attacks of September 11, 2001. The study was designed to determine predictors and correlates of risk and resilience, both cross-sectionally and longitudinally. In order to acquire timely and meaningful data, we developed/adapted an extensive set of measures, obtained human subjects approval, and posted a research Web site just 17 days after the attacks. This article describes the major hurdles we confronted and the guidelines we recommend regarding these topics, including the methodological trade-offs inherent in Internet-based research, information technology requirements and tribulations, human subjects issues, selection of measures and securing permission for their use, and the challenges of participant recruitment. We also discuss issues that we did not anticipate, including the survey intervention. We focus not on findings, but on the concrete procedural, administrative, technical, and scientific challenges we encountered and the solutions we devised under considerable time and resource pressures.
