The subjective feeling of free choice is an important feature of human experience. Experimental tasks have typically studied free choice by contrasting free and instructed selection of response alternatives. These tasks have been criticised, and it remains unclear how they relate to the subjective feeling of freely choosing. We replicated previous findings of the fMRI correlates of free choice, defined objectively. We introduced a novel task in which participants could experience and report a graded sense of free choice. BOLD responses for conditions subjectively experienced as free identified a postcentral area distinct from the areas typically considered to be involved in free action. Thus, the brain correlates of subjective feeling of free action were not directly related to any established brain correlates of objectively-defined free action. Our results call into question traditional assumptions about the relation between subjective experience of choosing and activity in the brain's so-called voluntary motor areas.

Background: This study aims to compare outcomes of colorectal cancer surgeries performed using the newly developed articulating laparoscopic instrument, ArtiSential, with those using conventional non-articulating or rigid laparoscopic instruments.
Methods: This multicenter, retrospective, matched cohort study enrolled patients with colorectal cancer undergoing laparoscopic surgery in seven tertiary referral hospitals from January 2021 to October 2022. A 1:1 propensity score matching was performed between the articulating (Arti-LAP) and conventional (Rigid-LAP) laparoscopic groups.

Background: The Thai government's initial response to the novel coronavirus disease 2019 (COVID-19) led to confusion and food insecurity in quarantined low-income communities. Although free food programs were initiated, no official assessment of their impact exists. The objective of this study was to evaluate the effectiveness of these food programs by surveying the food requirements, food needs, and health behaviors of quarantined, densely populated communities in Bangkok.

Target populationAdults with imaging suggestive of a WHO grade II diffuse gliomas (oligodendrogliomas or astrocytomas)QuestionIn adults with imaging suggestive of a WHO grade II diffuse gliomas (oligodendrogliomas or astrocytomas), does surgical resection improve overall survival compared to observation or biopsy?Updated Recommendation from the Prior Version of These Guidelines:Level III: In adults with imaging suggestive of a WHO grade II diffuse gliomas (oligodendrogliomas or astrocytomas), surgical resection is suggested over observation or biopsy to improve overall survival.Question Q2In adults with imaging suggestive of a WHO grade II diffuse gliomas (oligodendrogliomas or astrocytomas), does maximal surgical resection improve progression free survival (PFS) and overall survival (OS) compared to subtotal resection/biopsy?Unchanged Recommendations from the Prior Version of These GuidelinesLevel II It is recommended that GTR or STR be accomplished instead of biopsy alone when safe and feasible so as to decrease the frequency of tumor progression recognizing that the rate of progression after GTR is fairly high.Level III Greater extent of resection can improve OS in WHO grade II diffuse gliomas patients.

We investigated the association between values and attitudes toward sexual and reproductive health and rights (SRHR) and gender equality, with reproductive agency in Ethiopia, Kenya, and Zimbabwe. Using 2020-21 World Values Survey (WVS) data (n = 3,096), we utilized the SRHR Support Index including five subindices to gauge SRHR attitudes, the WVS Equality Index for gender equality values, and the perceived level of freedom of choice and control over whether, when, and how many children to have as a proxy for reproductive agency. Descriptive statistics, bivariate, and multivariable logistic regressions were used to analyse how values and attitudes differed between respondents of high vs low reproductive agency using the median as cutoff, stratified by country and sex.

People's understanding of topics and concepts such as risk, sustainability, and intelligence can be important for psychological researchers and policymakers alike. One underexplored way of accessing this information is to use free associations to map people's mental representations. In this tutorial, we describe how free association responses can be collected, processed, mapped, and compared across groups using the R package .
