A memory-based, Simon-like, spatial congruence effect: Evidence for persisting spatial codes

The Simon effect refers to the finding that in a task where stimulus location is irrelevant, reaction time is faster when stimulus and response locations are congruent than when they are not. Dominant theories of the Simon effect have generally attributed this spatial congruence effect to a spatial code automatically generated upon stimulus presentation. A common assumption of these theories is that this spatial code decays in less than a few hundred milliseconds following stimulus onset. We report two working-memory experiments suggesting a reexamination of this assumption—a Simon-like spatial congruence effect persisted over a delay of as long as 2400 ms. We propose that, in addition to generating short-lived perceptual codes, spatial information may be coded in working memory as part of the context associated with stimulus events. When reactivated by cues from the original event, such information may influence response selection and produce spatial congruence effects (in this case, positive when participants made a “yes” response and negative when they made a “no” response).     

Promoting Safe Driving Behaviors: The Influence of Message Framing and Issue Involvement

This study examined the influence of framing and issue involvement on the intentions of participants to perform safe driving behaviors. It was hypothesized that when participants were involved with the issue, gain messages would increase intentions to perform safe driving behaviors more than would loss messages. To examine this hypothesis, participants were classified as either being high or low in involvement, and then were required to read either a gain or a loss message promoting a particular safe-driving behavior. After reading the message, the participants' agreement with the message, cognitive and affective responses to the message, and intentions to perform the behavior were recorded. The results supported the hypothesis.     

Gatekeepers and the “Chomskian revolution”

The widely believed folk history of the confrontation between an established neo-Bloomfieldian generation and the revolutionary advances of transformational grammarians bears little relation to the open access to publication that Noam Chomsky encountered in the 1950s. Although a rhetoric of revolutionary conflict appeared, it cannot be attributed to attempts by the established generation to suppress new ideas, as in Thomas Kuhn's morphology of scientific revolutions. The central neo-Bloomfieldian gatekeeper, Bernard Bloch, fostered the diffusion of Chomsky's ideas and promoted the careers of Chomsky and Robert Lees. Other prominent neo-Bloomfieldians, regarding Chomsky as continuing the work of his teacher Zellig Harris, were sympathetic to his ideas and ready to concede his advances in syntactic theory. Nonetheless, Chomsky and his followers adopted an aggressive stance, denying the value of preceding work in structuralist linguistics. Although the case is anomalous for Kuhn's theory, it fits a sociological theory of scientific revolutions.
