On the Shoulders of Idiots: Re-thinking Science Communication as ‘Event’

Characterised by a shift from a diffusion to a deliberation model of science communication, the past decades have witnessed a proliferation of science communication formats. In order to better understand the complexity and novelty of these formats, we propose a ‘model of emergence’ that conceptualises science communication as an event in which the event itself, as well as the various actors that contribute to it, are emergent. To operationalise this model of emergence, we use Isabelle Stengers' figure of the idiot as an analytical tool which lets us interrogate our own implicit assumptions about science communication and the way they shape interactions in specific communication events. This makes it possible to be more sensitive to the ways in which we enable the emergence of particular identities and audience reactions, but also how we understand the role of science communicators themselves. A recent experiment with a science communication installation, ‘The Landscape of Expectations’, is used as an example that lets us trace how the ‘idiotic behaviours’ of visitors, which on one level make no sense, enable us to query presuppositions about the repertoire of behaviours available to the public and the assumed relations of power between experts and laypeople.     

Predictors of Post‐Event Rumination Related to Social Anxiety

Post‐event processing is the cognitive rumination that follows social events in cognitive models of social anxiety. The aim of this study was to examine factors that may predict the extent to which individuals engage in post‐event processing. Anxious rumination, social anxiety, anxiety sensitivity and post‐event processing related to a recent anxiety‐provoking social event were assessed in a college student sample (n = 439). Social anxiety and anxious rumination, but not anxiety sensitivity, significantly predicted the extent to which the participants engaged in post‐event processing related to an anxiety‐provoking social event. Factors that appear to impact on the post‐event period include the nature of the social situation and the ethnicity of the participant. It appears that both general rumination over anxious symptoms, and specific rumination related to social events are relevant for cognitive models of social anxiety.     

Positive emotion modulates cognitive control: An event‐related potentials study

There is substantial evidence to indicate that negative emotion can modulate cognitive control processing. However, only a few studies have investigated this effect with positive emotion. Therefore, the present study explored the electrophysiological correlates of the impact of positive emotional stimuli on cognitive control, using event‐related potentials (ERPs). Sixteen healthy young adults completed a modified Simon task (Simon, 1969). Behavioral data indicated that reaction times were faster for positive emotional stimuli than for neutral emotional stimuli in the incongruent condition, but not in the congruent condition, which suggested that positive emotion expedited conflict resolution. The ERP data showed that two negative ERP components (N300–400 and N450–550) were associated with the positive emotional stimuli in the incongruent minus congruent condition. It is suggested that these components may respectively be related to the conflict monitoring (N300–400) and response selection (N450–550) stages of cognitive control processing. Overall, our results indicated that positive emotion could facilitate cognitive control processing. These results are in line with the neuropsychological theory, according to which, positive emotion could modulate cognitive control mediated by increased dopamine levels in frontal brain areas.     

Cognitive control in belief‐laden reasoning during conclusion processing: An ERP study

Belief bias is the tendency to accept conclusions that are compatible with existing beliefs more frequently than those that contradict beliefs. It is one of the most replicated behavioral findings in the reasoning literature. Recently, neuroimaging studies using functional magnetic resonance imaging (fMRI) and event‐related potentials (ERPs) have provided a new perspective and have demonstrated neural correlates of belief bias that have been viewed as supportive of dual‐process theories of belief bias. However, fMRI studies have tended to focus on conclusion processing, while ERPs studies have been concerned with the processing of premises. In the present research, the electrophysiological correlates of cognitive control were studied among 12 subjects using high‐density ERPs. The analysis was focused on the conclusion presentation phase and was limited to normatively sanctioned responses to valid–believable and valid–unbelievable problems. Results showed that when participants gave normatively sanctioned responses to problems where belief and logic conflicted, a more positive ERP deflection was elicited than for normatively sanctioned responses to nonconflict problems. This was observed from ?400 to ?200 ms prior to the correct response being given. The positive component is argued to be analogous to the late positive component (LPC) involved in cognitive control processes. This is consistent with the inhibition of empirically anomalous information when conclusions are unbelievable. These data are important in elucidating the neural correlates of belief bias by providing evidence for electrophysiological correlates of conflict resolution during conclusion processing. Moreover, they are supportive of dual‐process theories of belief bias that propose conflict detection and resolution processes as central to the explanation of belief bias.     

Experimental manipulation of prior experience: Effects on item and associative recognition

Frequency of exposure to very low- and high-frequency words was manipulated in a three-phase (familiarisation, study, and test) design. During familiarisation, words were presented with their definition (once, four times, or not presented). One week (Experiment 1) or one day (Experiment 2) later, participants studied a list of homogeneous pairs (i.e., pair members were matched on background and familiarisation frequency). Item and associative recognition of high- and very low-frequency words presented in intact, rearranged, old-new, or new-new pairs were tested in Experiment 1. Associative recognition of very low-frequency words was tested in Experiment 2. Results showed that prior familiaris ation improved associative recognition of very low-frequency pairs, but had no effect on high-frequency pairs. The role of meaning in the formation of item-to-item and item-to-context associations and the implications for current models of memory are discussed.     

On the Distinction Between the Motivating Operation and Setting Event Concepts

In recent decades, behavior analysts have generally used two different concepts to speak about motivational influences on operant contingencies: setting event and motivating operation. Although both concepts still appear in the contemporary behavior-analytic literature and were designed to address the same antecedent phenomena, the concepts are quite different. The purpose of the present article is to describe and distinguish the concepts and to illustrate their current usage.     

How will things be the next time? Self in the construction of future events among school-aged children

This study examined among school-aged children the role of the self in perceived valence changes from the past to the future. Nine- to 11-year-old children (N = 57) recalled positive and negative personal events of various situations and imagined a future personal event involving the same situation following each recall. Children’s self-knowledge was assessed in terms of self-concepts for past, present, and future selves, and self-evaluations for social and cognitive competences. Children who viewed their future selves more positively and those who evaluated their cognitive competence more positively anticipated greater upward (positive) changes and smaller downward (negative) changes in their future academic performance. Children who evaluated their social competence more positively anticipated greater upward changes in their future peer relations. Furthermore, children who anticipated greater upward changes and smaller downward changes in their personal futures exhibited greater well-being. These findings shed new light on the role of self in mental time travel.     

Mental context reinstatement or drawing: Which better enhances children's recall of witnessed events and protects against suggestive questions?

The aim of this experiment was to examine the effectiveness of two techniques in enhancing children's recall of an event that they experienced approximately a week earlier. Younger (5–6 years) and older (8–9 years) children were interviewed about a magic show event in one of three conditions. Before recalling the event, some children were instructed to mentally reinstate the context of the event (MCR group), others were asked to draw the context of the event (DCR group), and others received no reinstatement instructions (NCR). Results showed that these instructions had no impact on children's free recall or responses to open‐ended prompts. However, reinstatement instructions impacted children's responses to suggestive questions: those in the DCR group gave more accurate responses than those in the NCR group. These findings provide preliminary support for the use of drawing as a potentially protective exercise that lessens the impact of biased questions with child witnesses.
