Reinventing the celts

This paper, based largely upon fieldwork in Glastonbury, gives an overview of some of the beliefs and speculations about Celts and Druids which are now circulating in certain New Age circles. In addition to some innovative ideas, elements of this new received wisdom are redolent of the antiquarian speculation of the 18th century. However, ‘Celticity’ is now being regarded by New Agers primarily as a quality rather than a matter of historical or geographical fact, and the Celts, with their enlightened priests the Druids, have become the Noble Savages of Britain.     

The persistence of false beliefs

Do false beliefs last? To explore this question, this study planted false beliefs or memories of a childhood experience with asparagus. We found that these false beliefs had consequences for subjects, when assessed directly after the suggestive manipulation. Moreover, subjects were brought back two weeks later to see if their false beliefs persisted. After two weeks, subjects' confidence in their new memories, and the consequences of those memories were diminished, but not extinguished. These false beliefs were found to be somewhat weaker than other subjects' true beliefs for the same events. Another novel finding was that the manipulation was sufficiently powerful to affect actual food choices.     

Evaluating Treatments for Functionally Equivalent Problem Behavior Maintained by Adult Compliance with Mands During Interactive Play

A primary goal of behavioral interventions is to reduce dangerous or inappropriate behavior and to generalize treatment effects across various settings. However, there is a lack of research evaluating generalization of treatment effects while individuals with functionally equivalent problem behavior interact with each other. For the current study, the severe problem behavior of two participants with developmental disabilities was targeted for assessment and treatment. Results of a functional analysis indicated that for both participants, problem behaviors occurred when destructive behavior produced reinforcement of participant mands . The use of a multiple schedule that alternated between differential reinforcement of other behaviors and differential reinforcement of alternative behavior (mands) was sufficient to produce a significant reduction in problem behavior for one participant; the addition of differential reinforcement of alternative behaviors via compliance was necessary for the second participant. Extended treatment sessions, which focused on interaction between the two participants, involved one therapist concurrently implementing each participant’s treatment while they were directed to play with one another (a situation that previously evoked problem behavior). Results show that each participant’s treatment produced low to zero rates of problem behavior even during extended interactions.     

Attentional episodes in visual perception

Is one's temporal perception of the world truly as seamless as it appears? This article presents a computationally motivated theory suggesting that visual attention samples information from temporal episodes (episodic simultaneous type/serial token model; Wyble, Bowman, & Nieuwenstein, 2009). Breaks between these episodes are punctuated by periods of suppressed attention, better known as the attentional blink (Raymond, Shapiro, & Arnell, 1992). We test predictions from this model and demonstrate that participants were able to report more letters from a sequence of 4 targets presented in a dense temporal cluster than from a sequence of 4 targets interleaved with nontargets. However, this superior report accuracy comes at a cost in impaired temporal order perception. Further experiments explore the dynamics of multiple episodes and the boundary conditions that trigger episodic breaks. Finally, we contrast the importance of attentional control, limited resources, and memory capacity constructs in the model.     

Neural correlates of facial emotion processing in infancy

In the present study we examined the neural correlates of facial emotion processing in the first year of life using ERP measures and cortical source analysis. EEG data were collected cross‐sectionally from 5‐ (N = 49), 7‐ (N = 50), and 12‐month‐old (N = 51) infants while they were viewing images of angry, fearful, and happy faces. The N290 component was found to be larger in amplitude in response to fearful and happy than angry faces in all posterior clusters and showed largest response to fear than the other two emotions only over the right occipital area. The P400 and Nc components were found to be larger in amplitude in response to angry than happy and fearful faces over central and frontal scalp. Cortical source analysis of the N290 component revealed greater cortical activation in the right fusiform face area in response to fearful faces. This effect started to emerge at 5 months and became well established at 7 months, but it disappeared at 12 months. The P400 and Nc components were primarily localized to the PCC/Precuneus where heightened responses to angry faces were observed. The current results suggest the detection of a fearful face in infants’ brain can happen shortly (~200–290 ms) after the stimulus onset, and this process may rely on the face network and develop substantially between 5 to 7 months of age. The current findings also suggest the differential processing of angry faces occurred later in the P400/Nc time window, which recruits the PCC/Precuneus and is associated with the allocation of infants’ attention.     

Real versus facsimile reinforcers on the Iowa Gambling Task

The Iowa Gambling Task (([Bechara et al., 1994]) is an effective neuropsychological tool for the assessment of 'real-life' decision-making in a laboratory environment. It has been employed in a wide range of circumstances, though researchers have sometimes employed real money reinforcers instead of the facsimile (or 'monopoly'-type) money used by. The present study investigated whether the type of reinforcer produced any differences in performance. There were no significant differences between the two conditions, though the Facsimile Money condition produced a greater range (and a higher standard deviation) than the Real Money condition. This finding is especially important when considering the Gambling Task as a tool in clinical neuropsychology--where there are risks, at the individual subject level, of both false positive and false negative classification errors.     

Devices of Responsibility: Over a Decade of Responsible Research and Innovation Initiatives for Nanotechnologies

Responsible research and innovation (RRI) has come to represent a change in the relationship between science, technology and society. With origins in the democratisation of science, and the inclusion of ethical and societal aspects in research and development activities, RRI offers a means of integrating society and the research and innovation communities. In this article, we frame RRI activities through the lens of layers of science and technology governance as a means of characterising the context in which the RRI activity is positioned and the goal of those actors promoting the RRI activities in shaping overall governance patterns. RRI began to emerge during a time of considerable deliberation about the societal and governance challenges around nanotechnology, in which stakeholders were looking for new ways of integrating notions of responsibility in nanotechnology research and development. For this reason, this article focuses on nanotechnology as the site for exploring the evolution and growth of RRI.     

Perceived Social Support and Mental Health among First-Year College Students with Histories of Bullying Victimization

Although childhood bullying victimization is associated with adult depression and anxiety, the majority of previously bullied youth do not develop psychopathology. Identifying protective factors has implications for designing interventions that can support a successful adjustment to emerging adulthood. In this study, we investigate whether perceived social support protects against depression and anxiety among first-year college students who had previously experienced bullying. We collected data from 1474 first-year college students attending four large universities across the United States. Students completed a web-based survey in fall 2012 (Wave 1) and 436 (29.5 %) participated in a follow-up survey in spring 2013 (Wave 2). Participants reported on childhood bullying victimization, current depression and anxiety, and current social support (overall and from family, friends, and significant others). Results indicated that a history of childhood bullying victimization was positively associated with depression and anxiety in both fall and spring. Further, overall social support reported in fall moderated the association between childhood bullying victimization and fall and spring anxiety. Also, higher levels of perceived family support, in particular, buffered previously bullied students’ risk for spring anxiety. Results suggest that perceptions of familial social support during the initial adjustment to college may protect previously bullied first-year students from anxiety during their adjustment to college. Research and clinical implications, study limitations, and future directions are discussed.
