Explaining happiness trends in Europe

In Europe, differences among countries in the overall change in happiness since the early 1980s have been due chiefly to the generosity of welfare state programs - increasing happiness going with increasing generosity and declining happiness with declining generosity. This is the principal conclusion from a time-series study of 10 Northern, Western, and Southern European countries with the requisite data. In the present study, cross-section analysis of recent data gives a misleading impression that economic growth, social capital, and/or quality of the environment are driving happiness trends, but in the long-term, time-series data, these variables have no relation to happiness

MEME-LaB : motif analysis in clusters

Genome-wide expression analysis can result in large numbers of clusters of co-expressed genes. While there are tools for ab initio discovery of transcription factor binding sites, most do not provide a quick and easy way to study large numbers of clusters. To address this, we introduce a web-tool called MEME-LaB. The tool wraps MEME (an ab initio motif finder), providing an interface for users to input multiple gene clusters, retrieve promoter sequences, run motif finding, and then easily browse and condense the results, facilitating better interpretation of the results from large-scale datasets

Autistic Adults Show Similar Performance and Sensitivity to Social Cues on a Visual Perspective Taking Task as Non-autistic Adults

Autistic and non-autistic adults completed a visual perspective taking (VPT) task, reporting an object’s location from an actor’s perspective, or their own. On half the trials the actor looked at and reached for the object, and on half did not. Accuracy and reaction time were measured. In Experiment 1, both groups (N = 34, mean age = 24 years) responded slower when reporting the actor’s perspective, with no group differences in this effect. Experiment 2 included “other” VPT trials only. Both groups (N = 30, mean age = 25 years) showed sensitivity to the actor’s behaviour, more accurately reporting his perspective when he acted upon the object. No group differences were observed. In contrast to developmental studies, these experiments suggest similar VPT abilities in autistic and non-autistic adults

Social intuition: behavioral and neurobiological considerations

Social intuition is instrumental in bringing about successful human interactions, yet its behavioral and neural underpinnings are still poorly understood. We focus in this article on the automatic, involuntary, nature of social intuition, rather than on higher-level cognitive and explicit Theory-of-Mind processes (which contribute to rendering social intuition meaningful in real-life situations). We argue that social-affective implicit learning plays a crucial role in establishing automatic social intuition. These implicit learning processes involve associations between the perception of other’s bodily articulations, concurrent events, and the consequences or outcomes in terms of subsequent actions, affective valences and visceral states. The traditional non-social implicit learning paradigms do not allow one to draw conclusions about the role of implicit learning processes in social intuition, as they lack these vital characteristics typically associated with human actions. We introduce a new implicit learning paradigm, which aims to fill these gaps. It targets agile, rapid, social-affective learning processes, involving cue contingencies with a relatively simple structure, unlike the very complex structures that underpin the traditional tasks. The paradigm features matching social and non-social versions, allowing direct comparison. Preliminary data suggest equal performance of TD (typically-developed) and ASC (autism spectrum conditions) groups on the non-social version, but impaired implicit learning in ASC on the social version. We hypothesize that this reflects an anomalous use of implicitly learned affective information in ASC when judging other people. We further argue that the mirror neuron mechanism (MNM), which is part of the Action Observation Network, forms an integral part of the neural substrate for social intuition. In particular as there are indications that the MNM supports action anticipation, and that implicitly learned information can trigger MNM activation, which both seem vital to a social intuition ability. The insights that can be derived from comparing the performances of TD and ASC individuals on (non)social implicit learning tasks, and the implications for the role of MNM activation, are discussed

Why would a special FM process exist in adults, when it does not appear to exist in children?

Cooper Greve, and Henson (this issue)  caution restraint before accepting that a fast mapping (FM) process exists in adults. We welcome this, but would also add that the original rationale for studying FM in adults is not currently supported by developmental research. Despite the claims of several adult FM researchers, there is little evidence from developmental word learning research for a special hippocampus-independent FM process critical for children’s word learning

Psychometric properties of the Sexual Attitudes and Beliefs Scale (SABS-C8) for health professionals in cancer care settings

BackgroundCancer and associated treatment can have a significant and detrimental impact on a person’s sexual wellbeing. Sexual attitudes and beliefs of healthcare professionals (HPs) working in cancer care settings can affect the support provided to help patients and partners to manage these concerns. This study evaluated psychometric properties of the Sexual Attitudes and Beliefs Scale (SABS-C8) adapted for use in cancer care settings.MethodsAdaptation of original SABS was informed by evidence reviews and an expert panel of researchers. The 12-item SABS was completed by HPs working in cancer care (n = 391) prior to completing an eLearning intervention aimed at promoting provision of sexual support to patients and partners. Exploratory (EFA) and confirmatory factor analysis (CFA) were conducted, reliability and validity of the scale were also explored.ResultsEFA showed potential for a three-factor model, with CFA indicating a better model fit (CMIN/DF < 3; GFI > .9; CFI > .9 and < RMSEA < .08) for 8 of the SABS-C items, lending support for a unidimensional model, with moderately acceptable reliability of.69. The 8-item scale was also able to discriminate between known groups with lower attitudinal barriers to providing sexual support apparent in HPs with over 12 years of experience, in nurses compared with other HPs, and in those with previous sexual wellbeing education (p < 0.001).ConclusionThe SABS-C8 is a brief scale with acceptable reliability that can be used to assess attitudinal barriers to sexual support and help to identify HPs learning needs around providing sexual support in cancer care

Attention and Recall of Point-of-sale Tobacco Marketing: A Mobile Eye-Tracking Pilot Study

Introduction: As tobacco advertising restrictions have increased, the retail ‘power wall’ behind the counter is increasingly invaluable for marketing tobacco products. Objective: The primary objectives of this pilot study were 3-fold: (1) evaluate the attention paid/fixations on the area behind the cash register where tobacco advertising is concentrated and tobacco products are displayed in a real-world setting, (2) evaluate the duration (dwell-time) of these fixations, and (3) evaluate the recall of advertising displayed on the tobacco power wall. Methods: Data from 13 Smokers (S) and 12 Susceptible or non-daily Smokers (SS) aged 180–30 from a mobile eye-tracking study. Mobile-eye tracking technology records the orientation (fixation) and duration (dwell-time) of visual attention. Participants were randomized to one of three purchase tasks at a convenience store: Candy bar Only (CO; N = 10), Candy bar + Specified cigarette Brand (CSB; N = 6), and Candy bar + cigarette Brand of their Choice (CBC; N = 9). A post-session survey evaluated recall of tobacco marketing. Key outcomes were fixations and dwell-time on the cigarette displays at the point-of-sale. Results: Participants spent a median time of 44 seconds during the standardized time evaluated and nearly three-quarters (72%) fixated on the power wall during their purchase, regardless of smoking status (S: 77%, SS: 67%) or purchase task (CO: 44%, CSB: 71%, CBC: 100%). In the post session survey, nearly all participants (96%) indicated they noticed a cigarette brand and 64% were able to describe a specific part of the tobacco wall or recall a promotional offer. Conclusions: Consumers are exposed to point-of-sale tobacco marketing, regardless of smoking status. FDA should consider regulations that limit exposure to point-of-sale tobacco marketing among consumers

Decision times in orthographic processing: a cross-linguistic study

Reading comparisons across transparent and opaque orthographies indicate critical differences that may reveal the mechanisms involved in orthographic decoding across orthographies. Here, we address the role of criterion and speed of processing in accounting for performance differences across languages. We used binary tasks involving orthographic (words–pseudowords), and non-orthographic materials (female–male faces), and analyzed results based on Ratcliff’s Diffusion model. In the first study, 29 English and 28 Italian university students were given a lexical decision test. English observers made more errors than Italian observers while showing generally similar reaction times. In terms of the diffusion model, the two groups differed in the decision criterion: English observers used a lower criterion. There was no overall cross-linguistic difference in processing speed, but English observers showed lower values for words (and a smaller lexicality effect) than Italians. In the second study, participants were given a face gender judgment test. Female faces were identified slower than the male ones with no language group differences. In terms of the diffusion model, there was no difference between groups in drift rate and boundary separation. Overall, the new main finding concerns a difference in decision criterion limited to the orthographic task: English individuals showed a more lenient criterion in judging the lexicality of the items, a tendency that may explain why, despite lower accuracy, they were not slower. It is concluded that binary tasks (and the Diffusion model) can reveal cross-linguistic differences in orthographic processing which would otherwise be difficult to detect in standard single-word reading tasks
