Can false memories prime problem solutions?

Previous research has suggested that false memories can prime performance on related implicit and explicit memory tasks. The present research examined whether false memories can also be used to prime higher order cognitive processes, namely, insight-based problem solving. Participants were asked to solve a number of compound remote associate task (CRAT) problems, half of which had been primed by the presentation of Deese/Roediger–McDermott (DRM) lists whose critical lure was also the solution to the problem. The results showed that when the critical lure: (a) was falsely recalled, CRAT problems were solved more often and significantly faster than problems that were not primed by a DRM list and (b) was not falsely recalled, CRAT problem solution rates and times were no different than when there was no DRM priming. A second experiment demonstrated that these outcomes were not a simple artifact of the inclusion of a recall test prior to the problem solving task. The implications of these results are discussed with regard to the previous literature on priming and the adaptive function of false memories.     

Socially anxious individuals lack unintentional mimicry

So far, evidence for unskilled social behavior in high socially anxious individuals (HAs) is equivocal. One reason may be that shortcomings are often not directly observable. An important shortcoming would be a lack of unintentional mimicry because it communicates sympathy and rapport with the interaction partner. Therefore, we tested whether HAs show less unintentional mimicry of others. Twenty-nine HAs and 43 low socially anxious individuals (LAs) - all female - watched a virtual man (avatar) who displayed a fixed set of head movements while giving an opinionated speech. Four raters scored whether the participants mimicked the avatar's movements within 4 s. The results indicate that HAs did indeed mimic significantly less than LAs. Lacking such pro-social behavior, HAs may indeed be evaluated as less sympathetic by others, confirming their fears of being disliked.     

Aesthetics and Affect: Engaging Energy Communities

ABSTRACT

Engaging publics in participatory events has become a central means to introducing lay people's voices into processes of technoscientific innovation and governance. However, little attention has been paid to the role of aesthetics, especially in terms of opening up potential ways of critically and creatively engaging with technoscientific matters of concern. The terms semblamatic and matters of potentially are proposed as addressing this dimension of aesthetics. Drawing on practice-based design research, a probe workshop with members of energy communities was implemented. Three probe exercises served to open up potential re-articulations of such core themes as energy, communities and futures. Our goals were to examine the whether such probes enabled semblamatic responses and the emergence of matters of potentiality. Findings were mixed. The continued retention of standard meanings of these core themes suggested that such events can be anaesthetic, blunting access to the semblamatic aspects of engagement. Conversely, there was some opening up in which the core themes were creatively re-articulated. The present perspective, with its three novel terms - semblamatic, matters of potentiality, and anaesthetic - might prove useful in alerting scholars to the complex role of aesthetics in the methodological and analytic practices entailed in engagement with publics.     

Naming faces and naming names: Exploring an interactive activation model of person recognition

Abstract

In this paper we present an interactive activation and competition (LAC) model of name recognition. This is an extension of a previous account of name retrieval (Burton & Bruce, 1992) and is based on a functional model due to Valentine, Bredart, Lawson, and Ward (1991). Several empirical effects of name recognition are simulated: (1) names that are known are read faster than names that are unknown; (2) common names are read faster than rare names; and (3) rare names are recognised as familiar faster than common names. The simulations demonstrate that these complex effects can arise as a natural consequence of the architecture of the LAC model. Finally, we explore a modification of the Valentine et al. functional model, and conclude that the model as originally proposed is best able to account for the available data.     

Warmth and Contingency and Their Relationship to Maternal Attitudes Toward Parenting

In this study, the authors addressed the question of whether maternal parenting behaviors in terms of sensitivity, warmth, and contingency with respect to small infants were equally represented in attitudes toward parenting. Sixty mothers from central Germany with middle-class socioeconomic backgrounds were videotaped with their 1st born 3-month-old infant in a free-play and a caregiving episode in their home. The different maternal parenting components were behaviorally analyzed. Maternal attitudes toward parenting were assessed with self-report measures. The results showed that behavioral sensitivity was significantly associated with attitudes related to contingency, whereas behavioral warmth and contingency were not associated with maternal attitudes. The authors interpreted differential associations as a reflection of intuitive and explicit parenting strategies, with only sensitivity being explicitly represented.     

Implicit evaluation bias induced by approach and avoidance

We report a study in which faces with a neutral emotional expression were shown on a computer screen. By means of a joystick, participants pulled half of the faces closer (positive approach movement), and pushed the half away (negative avoidance movement). As a result, an operant evaluative conditioning effect occurred in a subsequent affective priming task: Participants responded more quickly to positive target words if they were preceded by a previously pulled face than a pushed face, and vice versa for negative target words. The effect became stronger the more often the faces had been trained to approach or to avoid. No effect was observed on explicit evaluations of the faces: Pushed faces were rated as sympathetic as pulled ones.     

Attentional and behavioural responses of spider fearfuls to virtual spiders

This study employed an immersed virtual environment (IVE) in the Nijmegen RIVERlab to study spider fearfuls’ attentional and motor reactions to virtual spiders. The participants were exposed to virtual spiders while completing an unrelated task, walking freely through a virtual museum. Compared to non-fearful controls, spider fearfuls showed an increase in state anxiety, they spent more time looking at spiders, and they exhibited spontaneous behavioural avoidance of spiders and visually similar objects. The results extend, and to some degree contradict, those of earlier studies with static pictures, and they speak to the usefulness of state-of-the-art IVEs in fundamental anxiety research.     

Twin-earth externalism and concept possession

It is widely believed that Twin-Earth-style thought experiments show that the contents of a person's thoughts fail to supervene on her intrinsic properties. Several recent philosophers have made the further claim that Twin-Earth-style thought experiments produce metaphysically necessary conditions for the possession of certain concepts. I argue that the latter view is false, and produce counterexamples to several proposed conditions. My thesis is of particular interest because it undermines some attempts to show that externalism is incompatible with privileged access.
