» Poverty and decision-making: How behavioural science can improve opportunity in the UK | The Behavioural Insights Team

See on Scoop.itBounded Rationality and Beyond

A third of the UK population spent at least one year in relative income poverty between 2011 and 2014. Traditionally policymakers and anti-poverty organisations such as the Joseph Rowntree Foundation (JRF) have focused on boosting people’s economic capital (e.g., income) and human capital (e.g., educational attainment) to reduce poverty. While investments in these areas have led to important gains in opportunity for many Britons, emerging research from behavioural science shows that other less tangible resources, which derive from psychological, social and cultural processes, significantly influence people’s ability to overcome disadvantage. BIT was commissioned by JRF to examine the role of individual decisions in shaping people’s experiences of poverty in the UK and to identify the drivers of these decisions. This reflects JRF’s interest in looking beyond traditional, structural drivers of poverty. Our findings, based on a review of the published literature, are presented in a new report, launched today. Building on the concepts of economic and human capital, our report proposes a more expansive capital-based model of poverty and decision-making, encompassing environmental, social, character and cognitive capital (Figure 1). For example, an individual may use their social capital (e.g., trusted social connections) to identify labour market opportunities; but being low in environmental capital (e.g., overcrowded housing) may reduce opportunities for parents to talk with their child in ways that build their human capital (e.g., speech development).

When That Tune Runs Through Your Head: A PET Investigation of Auditory Imagery for Familiar Melodies

See on Scoop.itBounded Rationality and Beyond

The present study used positron emission tomography (PET) to examine the cerebral activity pattern associated with auditory imagery for familiar tunes. Subjects either imagined the continuation of nonverbal tunes cued by their first few notes, listened to a short sequence of notes as a control task, or listened and then reimagined that short sequence. Subtraction of the activation in the control task from that in the real-tune imagery task revealed primarily right-sided activation in frontal and superior temporal regions, plus supplementary motor area (SMA). Isolating retrieval of the real tunes by subtracting activation in the reimagine task from that in the real-tune imagery task revealed activation primarily in right frontal areas and right superior temporal gyrus. Subtraction of activation in the control condition from that in the reimagine condition, intended to capture imagery of unfamiliar sequences, revealed activation in SMA, plus some left frontal regions. We conclude that areas of right auditory association cortex, together with right and left frontal cortices, are implicated in imagery for familiar tunes, in accord with previous behavioral, lesion and PET data. Retrieval from musical semantic memory is mediated by structures in the right frontal lobe, in contrast to results from previous studies implicating left frontal areas for all semantic retrieval. The SMA seems to be involved specifically in image generation, implicating a motor code in this process.
