Mind-reading without the scanner: Behavioural decoding of working memory content

ABSTRACT

Sophisticated machine learning algorithms have been successfully applied to functional neuroimaging data in order to characterize internal cognitive states. But is it possible to “mind-read” without the scanner? Capitalizing on the robust finding that the contents of working memory guide visual attention toward memory-matching objects, we trained a multivariate pattern classifier on behavioural indices of attentional guidance. Working memory representations were successfully decoded from behaviour alone, both within and between individuals. The current study provides a proof-of-concept for applying machine learning techniques to simple behavioural outputs (e.g., response times) in order to decode information about specific internal cognitive states.     

Similarity to prototypical heavy drinkers and non-drinkers predicts AUDIT-C and risky drinking in young adults: prospective study

Objective: The aim of the present study was to explore whether constructs within the Prototype Willingness Model (PWM) predicted risky drinking as measured by AUDIT-C, drinking harms and unplanned drunkenness in a sample of UK young adults. Previous studies exploring the PWM often do not use validated measures of alcohol consumption, and the outcomes of risky drinking are underexplored. Design: An online prospective study design with 4 week follow-up was employed and 385 young adults completed the study (M age?=?21.76, SD?=?3.39, 69.6% female; 85.2% students). Main outcome measures: Intentions to get drunk, AUDIT-C, drinking harms experienced in the last 4 weeks, and unplanned drunkenness in the last 4 weeks. Results: Heavy and non-drinker prototype similarity predicted AUDIT-C, drinking harms and unplanned drunkenness when controlling for past behaviour and reasoned action pathway constructs. Intentions and willingness both mediated the relationship between prototype perceptions and AUDIT-C. Conclusion: This study supports the use of the PWM in the prediction of AUDIT-C, drinking harms and unplanned drinking in a UK sample. Prototype perceptions influenced behaviour via both reasoned and reactive cognitions. Targeting similarity to heavy and non-drinker prototypes should be the focus of future interventions in this population.     

Genetic Counseling in the Era of Genomics: What’s all the Fuss about?

As genomic sequencing becomes more widely available in clinical settings for diagnostic purposes, a number of genetic counseling issues are gaining precedence. The ability to manage these issues will be paramount as genetic and non-genetic healthcare professionals navigate the complexities of using genomic technologies to facilitate diagnosis and inform patient management. Counseling issues arising when counseling for diagnostic genomic sequencing were identified by four genetic counselors with 10 years of collective experience providing genetic counseling in this setting. These issues were discussed and refined at a meeting of genetic counselors working in clinical genomics settings in Melbourne, Australia. Emerging counseling issues, or variations of established counseling issues, were identified from the issues raised. Illustrative cases were selected where pre- and post-test genetic counseling was provided in clinical settings to individuals who received singleton or trio WES with targeted analysis. Counseling issues discussed in this paper include a reappraisal of how genetic counselors manage hope in the genomic era, informed consent for secondary use of genomic data, clinical reanalysis of genomic data, unexpected or unsolicited secondary findings, and trio sequencing. The authors seek to contribute to the evolving understanding of genetic counseling for diagnostic genomic sequencing through considering the applicability of existing genetic counseling competencies to managing emerging counseling issues and discussing genetic counseling practice implications.     

Object onset and parvocellular guidance of attentional allocation

The parvocellular visual pathway in the primate brain is known to be involved with the processing of color. However, a subject of debate is whether an abrupt change in color, conveyed via this pathway, is capable of automatically attracting attention. It has been shown that the appearance of new objects defined solely by color is indeed capable of modulating attention. However, given evidence suggesting that the visual system is particularly sensitive to new onsets, it is unclear to what extent such results reflect effects of color change per se, rather than effects of object onset. We assessed attentional capture by color change that occurred as a result of either new objects appearing or already-present "old" objects changing color. Results showed that although new object onsets accrued attention, changing the color of old objects did not. We conclude that abrupt color change per se is not sufficient to capture attention.     

‘He's got his father's bias’: Parental influence on weight bias in young children

Our aim was to explore the role of parents in the transmission of stereotypical body size attitudes and awareness of weight loss strategies to preschool children. Participants were 279 3‐year‐old children and their parents, who provided data at baseline and 1 year later. Parents completed self‐report body size attitude and dieting measures. Child weight bias and awareness of weight loss strategies were assessed through interview. Over time, negative associations with large bodies and awareness of weight loss strategies increased. Fathers’ attitudes prospectively predicted boys’ weight bias and awareness of weight loss strategies. Among girls, parental attitudes were less predictive. Findings confirm the importance of fathers in the development of boys’ body attitudes and inform prevention programmes.

The use of the political categories of Brexiter and Remainer in online comments about the EU referendum

In June 2016, the United Kingdom held a referendum on EU membership; 52% of those who voted, voted to leave, and 48% voted to remain. During the referendum campaign, two identities emerged: “Brexiter” and “Remainer,” which remained salient post‐referendum. This study explores how the categories of Brexiter and Remainer were deployed by posters online. Data comprise comment threads collected from four online newspapers both during the campaign and after the vote, which focus on the Brexit campaign promise: “We send £350m a week to the EU. Let's fund our NHS instead.” We draw on membership categorization analysis and discursive psychology to analyse when categories were made salient and what responses to the invocation of categories were. Analysis revealed that posters explicitly categorize the out‐group and in doing so implicitly define their group. Posters resisted other political identities when attributed to them in relation to the referendum. The analysis shows how Brexiter and Remainer are new, albeit contested, political categories and identities in their own right, with other political identities resisted when used. The paper highlights implications for the political system in the United Kingdom and for social divisions within U.K. society.     

How Palestinian students invoke the category “human” to challenge negative treatment and media representations

Dehumanisation of opponents in conflict has been shown to be a common and damaging feature in the media. What is not understood is how this dehumanisation is challenged, which is the novel contribution that this research will make. Drawing on focus groups (four focus groups each with four to six participants) conducted in the West Bank in 2015 that discussed media coverage of international conflict, this article demonstrates the ways in which young Palestinian participants attempt to rehumanize themselves in the context of the Israeli–Palestinian conflict. Discursive analysis demonstrates how this was achieved in a number of ways: categorising Palestinians as “human being”; by directly and explicitly challenging the suggestion that Palestinians are less than human; by drawing the enemy into the category “human”; and by embodying the “human.” These findings, the first to address the talk of young Palestinians about the reporting of violent conflicts around the world, demonstrate the importance of categorization and how, in this case, the specifics of the use of the (human) category work to rehumanize Palestinians in the face of (claims of) dehumanisation.
