Cultural differences in the primacy effect for person perception.

Previous work has shown there are robust differences in how North Americans and East Asians form impressions of people. The present research examines whether the tendency to weigh initial information more heavily-the primacy effect-may be another component of these cultural differences. Specifically, we tested whether Americans would be more likely to use first impressions to guide person perception, compared to Japanese participants. In this experiment, participants read a vignette that described a target person's behaviour, then rated the target's personality. Before reading the vignette, some trait information was given to create an expectation about the target's personality. The data revealed that Americans used this initial information to guide their judgments of the target, whereas the Japanese sample based their judgments on all the information more evenly. Thus, Americans showed a stronger primacy effect in their impression formation than Japanese participants, who engaged in more data-driven processing.

The photoconvertible water-soluble chlorophyll-binding protein of Chenopodium album is a member of DUF538, a superfamily that distributes in Embryophyta.

Various plants possess hydrophilic chlorophyll (Chl) proteins known as water-soluble Chl-binding proteins (WSCPs). WSCPs exist in two forms: Class I and Class II, of which Class I alone exhibits unique photoconvertibility. Although numerous genes encoding Class II WSCPs have been identified and the molecular properties of their recombinant proteins have been well characterized, no Class I WSCP gene has been identified to date. In this study, we cloned the cDNA and a gene encoding the Class I WSCP of Chenopodium album (CaWSCP). Sequence analyses revealed that CaWSCP comprises a single exon corresponding to 585bp of an open reading frame encoding 195 amino acid residues. The CaWSCP protein sequence possesses a signature of DUF538, a protein superfamily of unknown function found almost exclusively in Embryophyta. The recombinant CaWSCP was expressed in Escherichia coli as a hexa-histidine fusion protein (CaWSCP-His) that removes Chls from the thylakoid. Under visible light illumination, the reconstituted CaWSCP-His was successfully photoconverted into a different pigment with an absorption spectrum identical to that of native CaWSCP. Interestingly, while CaWSCP-His could bind both Chl a and Chl b, photoconversion occurred only in CaWSCP-His reconstituted with Chl a.

Interactive effects of carbon footprint information and its accessibility on value and subjective qualities of food products.

We aimed to explore the interactive effects of the accessibility of information and the degree of carbon footprint score on consumers' value judgments of food products. Participants (n=151, undergraduate students in Japan) rated their maximum willingness to pay (WTP) for four food products varying in information accessibility (active-search or read-only conditions) and in carbon footprint values (low, middle, high, or non-display) provided. We also assessed further effects of information accessibly and carbon footprint value on other product attributes utilizing the subjective estimation of taste, quality, healthiness, and environmental friendliness. Results of the experiment demonstrated an interactive effect of information accessibility and the degree of carbon emission on consumer valuation of carbon footprint-labeled food. The carbon footprint value had a stronger impact on participants' WTP in the active-search condition than in the read-only condition. Similar to WTP, the results of the subjective ratings for product qualities also exhibited an interactive effect of the two factors on the rating of environmental friendliness for products. These results imply that the perceived environmental friendliness inferable from a carbon footprint label contributes to creating value for a food product.

Intuitions about situational correction in self and others.

People's attributional phenomenology is likely to be characterized by effortful situational correction. Drawing on this phenomenology and on people's desire to view themselves more favorably than others, the authors hypothesized that people expect others to engage in less situational correction than themselves and to make more extreme dispositional attributions for constrained actors' behavior. In 2 studies, people expected their peers to make more extreme dispositional inferences than they did themselves for a situationally constrained actor's behavior. People's expectation that they engage in more situational correction than their peers was diminished among Japanese participants, who have less desire to view themselves as superior to their peers (Study 3), and among participants who were led to view dispositional attributions more favorably than situational attributions (Study 4).
