Sentence understanding and knowledge of the world: Evidences from a sentence-picture matching task performed by aphasic patients

The abilities of aphasic patients to perform a sentence-picture matching task were investigated on simple declarative reversible sentences. Two factors were found to differentially affect Broca's versus Wernicke's aphasics' performance: sentence plausibility and spatial arrangement. Sentence plausibility, that is to say, the liability of two given nouns in a sentence to act as agent and recipient according to normal subjects' expectancies, had a significant effect on the frequency of correct responses of Broca's aphasics but not on those of Wernicke's. Conversely, the latter were found to be more sensitive to a match or mismatch in the left-to-right spatial arrangement of the grammatical subject and object in a sentence on the one hand, and the order of the corresponding personages in the picture on the other. The results are discussed in terms of “frame selection” and the handling of ordered structure strategies contributing to normal system, but selectively disturbed in the case of brain damage.     

Learning to program in LISP

We have gathered protocols of subjects in their first 30 hours of learning LISP. The processes by which subjects write LISP functions to meet problem specifications has been modeled in a simulation program called GRAPES (Goal Restricted Production System). The GRAPES system embodies the goal-restricted architecture for production systems as specified in the ACT* theory (Anderson, 1983). We compare our simulation to human protocols on a number of problems. GRAPES simulates the top-down, depth-first flow of control exhibited by subjects and produces code very similar to subject code. Special attention is given to modeling student solutions by analogy, how students learn from doing, and how failures of working memory affect the course of problem-solving. Of major concern is the process by which GRAPES compiles operators in solving one problem to facilitate the solution of later problems.     

Common barriers to healthcare for transgender people in the U.S. Southeast

Abstract

Background: Transgender and non-binary people are more likely to face barriers to healthcare than their cisgender counterparts. The majority of work in this area centers on the experiences of transgender people in northern cities and urban enclaves, yet over 500,000 transgender people live in the U.S. Southeast.

Aims: The purpose of this study is to explore barriers to healthcare among transgender people in the U.S. Southeast.

Methods: The research team conducted four 120-minute focus groups (eligibility criteria: 18?years or older, self-identify as transgender, live in the U.S. Southeast). Participants completed a demographic questionnaire prior to the start of the focus group. Each focus group explored access to and experiences of receiving basic healthcare as a transgender person in the U.S. Southeast. Established qualitative methods were used to conduct the focus groups and data analysis.

Results: Participants (n?=?48) ranged in age from 19 to 65, with the majority identifying as trans women (43.8%) and non-binary (33.3%). The sample was racially diverse: White (50%), Black (37.5%), and Latinx or Multiracial (12.5%). Multiple barriers to care were identified: (1) fear and mistrust of providers; (2) inconsistency in access to healthcare; (3) disrespect from providers; and, (4) mistreatment due to intersecting experiences of gender, race, class, and location.

Discussion: Transgender Southerners face barriers to care at the structural, cultural, and interpersonal levels. The study results have implications for researchers, as well as providers, practices, and health care systems throughout the region.     

THE MORALITY,POLITICS, AND IRONY OF WAR: Recovering Reinhold Niebuhr's Ethical Realism

The American experience of war is ironic. That is, there is often an intimate and unexamined relationship between seemingly contrary elements in war such as morality and politics. This article argues that without understanding such irony, we are unlikely to reflect in morally comprehensive ways on past, present, or future wars. Traditional schools of thought, however, such as moralism and political realism, reinforce these apparent contradictions. I propose, then, an alternative—“ethical realism” as informed by Reinhold Niebuhr—that better explains the irony of war. Through an ethical realist examination of the U.S. Civil War, World War II, and the Iraq War, I consider how American political interests have been inextricably linked with deep moral concerns. Ethical realism charts a middle path that ennobles traditional realpolitik while eschewing certain perfectionist tendencies of moralism. Ethical realism provides a conceptual framework for evaluating these other frameworks—a distinct form of moral‐political deliberation about war.     

A test of the X-linked genetic hypothesis for sex differences on Piaget's water-level task

Data from seven studies involving 849 high school and college students were used to test the recessive X-linked genetic model prediction that the square of the proportion of men who perform accurately on the water-level task is equal to the proportion of women who perform accurately. Goodness-of-fit tests showed that this prediction was confirmed for each sample. A model with a single estimate of gene frequency accounted for all the data when a classification error parameter was incorporated into the X-linked model. In both models the gene frequency parameter was about $\text{2}\text{3}$.     

Reading skill and language skill

To learn to read is to acquire a visual language skill which systematically maps onto extant spoken language skills. Some children perform this task quite adeptly while others encounter much difficulty, and it has become a question of both scientific and practical merit to ask why there exists such a range of success in learning to read. Obviously, learning to read places a complex burden on many emerging capacities, and in principle, at least, reading disability could arise at any level from visual perception to general cognition. Yet since reading is parasitic on spoken language, the possibility also exists that reading disability is derived from some subtle difficulty in the language domain. This article reviews some of the many studies which have explored the association between early reading skills and spoken language skills. The focus will be on findings which reveal that when the linguistic short-term memory skills of good and poor beginning readers are critically examined, considerably many, though perhaps not all, poor readers prove to possess subtle deficiencies which correlate with their problems in learning to read.
