Effects of perceptual fluency on judgments of truth.

Statements of the form "Osorno is in Chile" were presented in colors that made them easy or difficult to read against a white background and participants judged the truth of the statement. Moderately visible statements were judged as true at chance level, whereas highly visible statements were judged as true significantly above chance level. We conclude that perceptual fluency affects judgments of truth.     

Green Dreams of Reason. Green Nanotechnology Between Visions of Excess and Control

Nanotechnology has recently been identified with principles of sustainability and with a ‘green’ agenda generally. Some maintain that this green dream of nanotechnology is a rather ephemeral societal phenomenon that owes its existence to the campaign ploys of politics and business. This paper argues that deeper lying societal and cognitive structures are at work here that complement or even substantiate in some sense the seemingly manipulative saying of a greening of nanotechnologies. Taking seriously the concept of ‘green nano’, this paper examines the common ground between sustainability discourse and the discourse of nanotechnology. Green nanotechnology is understood as a boundary concept in which disparate discourses and concepts join together. The primary concern of the paper is to show that nanodiscourse and ecodiscourse share visions of control and of excess. Both ecotechnology and nanotechnology accept and incorporate arguments about limited growth, and each develops strategies of control—be it through a new-found precision in the control of material flows or through greater efficiency in product design.     

How extending your middle finger affects your perception of others: Learned movements influence concept accessibility

Body movements both express and influence how people feel and think. Conceptualizations of this bidirectional influence assume that movement-concept associations can be innate or learned, although evidence for learned associations remained ambiguous. Providing a conservative test of learned movement-concept associations, two studies investigate the influence of culture-specific body movements, which involve an arbitrary relationship between movements and associated concepts. Paralleling the influence of hostility primes, extending the middle finger influenced the interpretation of ambiguously aggressive behaviors as hostile, but did not influence unrelated trait judgments (Study 1). Paralleling the effects of global evaluative primes, upward extension of the thumb resulted in more positive evaluations of the same target along all trait dimensions and higher liking of the target (Study 2).     

Argumentation and Explanation in Conceptual Change: Indications From Protocol Analyses of Peer-to-Peer Dialog

In this paper we attempt to identify which peer collaboration characteristics may be accountable for conceptual change through interaction. We focus on different socio-cognitive aspects of the peer dialog and relate these with learning gains on the dyadic as well as the individual level. The scientific topic that was used for this study concerns natural selection, a topic for which students' intuitive conceptions have been shown to be particularly robust. Learning tasks were designed according to the socio-cognitive conflict instructional paradigm. After receiving a short instructional intervention on natural selection, paired students were asked to collaboratively construct explanations for certain evolutionary phenomena while engaging in dialectical argumentation. Two quantitative coding schemes were developed, each with a different granularity. The first assessed discrete dialog moves that pertained to dialectical argumentation and to consensual explanation development. The second scheme characterized the dialog as a whole on a number of socio-cognitive dimensions. Results from analyses on the dyadic as well as the individual level revealed that the engagement in dialectical argumentation predicted conceptual learning gains, whereas consensual explanation development did not. These findings open up new venues for research on the mechanisms of learning in and from peer collaboration.     

Financial aspirations,financial success,and overall life satisfaction: who? and how?

Nickerson et al. (2003, Psychological Science 14, pp. 531–536) demonstrated in a longitudinal study that the negative relation between aspirations for financial success and subjective well-being found by other researchers was mitigated by high household income. The present study first refined the analysis in Nickerson et al. (2003) and then explored two additional issues: (a) who aspires to financial success? and (b) how is financial success achieved? Analysis indicated that individuals with strong financial aspirations are socially inclined, confident, ambitious, politically conservative, traditional, conventional, and relatively less able academically, but not psychologically distressed. Financial success is achieved via the job and, for women only, via marriage. Financial aspirations influence job income both by influencing choice of occupation and by influencing job income within occupation; however, achieving financial success depends on having the personal resources to do so. Women with strong financial aspirations tend to marry for money (or money-making potential) regardless of their work status; men with strong financial aspirations do not.     

Context effects in political judgement: assimilation and contrast as a function of categorization processes

Two experiments demonstrate that thinking about a given politician may result in assimilation as well as contrast effects in evolutions of the politician's party. In two experiments, assimilation effects were observed when an experimental categorization task elicited the inclusion of a highly respected politician in the representation formed of his party, whereas contrast effects were observed when the categorization task elicited his exclusion from the representation, with the control group falling in between. Hence, the same information may elicit assimilation as well as contrast effects, depending on its use in mental construal. © 1998 John Wiley & Sons, Ltd.     

"1-2-3": is there a temporal number line? Evidence from a serial comparison task

Evidence suggests that numbers are intimately related to space (Dehaene, Bossini, & Giraux, 1993; Hubbard, Piazza, Pinel, & Dehaene, 2005). Recently, Walsh (2003) suggested that numbers might also be closely related to time. To investigate this hypothesis we asked participants to compare two digits that were presented in a serial manner, i.e., one after another. Temporally ascending digit pairs (such as 2-3) were responded to faster than temporally descending pairs (3-2). This effect was, in turn, qualified by a local SNARC (spatial numerical association of response codes) effect and a local semantic congruity effect (SCE). Moreover, we observed a global numerical SCE only for temporally descending digit pairs. However, we did not observe a global SNARC effect, i.e., an interaction of numerical magnitude and the right/left response hand. We discuss our results in terms of overlearned forward-associations ("1-2-3") as formed by our ubiquitous cognitive routines to count off objects or events.
