Spatial transposition tasks assess individuals' ability to represent nonvisible spatial object displacements. Several nonhuman mammal species have been tested on this task including primates, cats, and dogs, but to date, great apes seem the only taxon that has repeatedly and consistently solved spatial transposition tasks. The authors investigated the ability of captive sloth and sun bears to solve spatial transposition tasks. Both species belong to the same taxonomic group as cats and dogs, but unlike them and similar to apes, they have an omnivorous diet that requires them to keep track of fruit sources in space and time...

Micah B Goldwater
This paper argues that grammatical constructions, specifically argument structure constructions that determine the "who did what to whom" part of sentence meaning and how this meaning is expressed syntactically, can be considered a kind of relational category. That is, grammatical constructions are represented as the abstraction of the syntactic and semantic relations of the exemplar utterances that are expressed in that construction, and it enables the generation of novel exemplars. To support this argument, I review evidence that there are parallel behavioral patterns between how children learn relational categories generally and how they learn grammatical constructions specifically...

Psychology is a required element in nursing education in many countries. It is particularly aimed at teaching nursing students to get a better understanding of patients, colleagues, health care organizations and themselves, and moreover to apply what they learn about psychology to optimise their care. A meaningful integration of psychology within nursing education requires an emphasis on its application in understanding aspects of care and skills development. However, its ultimate value is demonstrated when addressing problem areas in nursing and health care...

BACKGROUND: The term self-determination refers to decision-making, goal setting, and perseverance to achieve those goals. Numerous studies have established the importance of self-determination to enhance learning and improve post-school outcomes. However, most studies evaluate students with learning disabilities, cognitive impairment, or behavioral disabilities. There is an absence of research on self-determination for adolescents with physical disabilities. OBJECTIVE: To assess self-determination of adolescents with neonatal brachial plexus palsy (NBPP) compared to their typically developing peers via self-reported measures of function...

BACKGROUND AND AIMS: Colonoscopy competency assessment in trainees have traditionally been informal. Comprehensive metrics such as the Assessment of Competency in Endoscopy (ACE) tool suggest competency thresholds are higher than assumed. cap-assisted colonoscopy (CAC) may improve competency but data in novice trainees are lacking. We compare CAC versus standard colonoscopy (SC) among novice trainees in a randomized controlled trial. METHODS: All colonoscopies performed by 3 gastroenterology fellows without prior experience were eligible for enrollment...

Young children have difficulty in distinguishing events that violate physical laws (impossible events) from those that violate mere physical regularities (improbable events). They judge both as "impossible." Young children also have difficulty in distinguishing events that violate moral laws (immoral events) from events that violate mere social regularities (unconventional events). They judge both as "wrong." In this set of studies, we explored the possibility that both difficulties arise from a more general deficit in modal cognition, or the way in which children represent and reason about possibilities...

Brain structure and functions are significantly affected by enriched environment (EE). Rodent and rhesus monkeys raised in EE will increase myelination in development, and these increase correlate with improved cognitive functions on learning and memory. However, whether and how EE influences remyelination in the adult remained undefined. Here, we used a cuprizone-induced demyelination mouse model demonstrate that EE significantly enhances remyelination. This EE-regulated remyelination is associated with improved motor skills...

This study explores the effect of individual differences in the age of acquisition of a second language using resting-state functional magnetic resonance imaging (rs-fMRI) to examine functional connectivity and its relation with cognitive control within bilinguals. We compared simultaneous bilinguals, who learned two languages from birth, to sequential bilinguals, who learned a second language following mastery of their first language. Results show an effect of language experience on the strength of anticorrelation between the default mode network and the task-positive attention network and on cognitive control, with simultaneous bilinguals demonstrating stronger anticorrelations between the two networks, as well as superior cognitive control compared to sequential bilinguals...

The present systematic review examines whether very low nicotine content (VLNC) cigarettes ameliorate withdrawal-induced impairments in behavioral/cognitive performance. PubMed, PsycInfo, and Web of Science were searched for performance effects of VLNC cigarettes. For inclusion, reports had to be in English, published in a peer-reviewed journal through June 2017, examine VLNC cigarettes (<0.2mg nicotine yield), include ≥2hour smoking abstinence or reduced nicotine exposure, and examine performance. 19 of 1243 articles reviewed met inclusion criteria...

Persistent negative and cognitive symptoms in patients with schizophrenia pose a significant challenge to clinicians. Being a heterogeneous cluster of symptoms with potentially distinct underlying pathogenesis, it is important to examine novel therapies based on emerging neurobiological evidence. Eszopiclone is known to enhance the deficient sleep spindles that are related to impairments in learning and memory in schizophrenia. In this report we highlight the potential utility of eszopiclone in treating persistent negative symptoms in a patient with chronic schizophrenia...

The aim of the present study is to elucidate the neuronal pathways associated to NSAIDs causing a reduction of the risk and progression of Alzheimer's disease. The research was developed administering the active enantiomer of ibuprofen, dexibuprofen (DXI), in order to reduce associated gastric toxicity. DXI was administered from three to six-month-old female APPswe/PS1dE9 mice as a model of familial Alzheimer's disease. DXI treatment reduced the activation of glial cells and the cytokine release involved in the neurodegenerative process, especially TNFα...

Currently, there is no formal curriculum addressing geriatric oncology within Canadian radiation oncology (RO) residency programs. Knowledge related to geriatric medicine may help radiation oncologists modify RT based on frailty status and geriatric considerations. Understanding specific learning needs allow program coordinators to align the current curriculum with residents' geriatric oncology learning needs. The purpose of this study is to determine the geriatric oncology educational needs of the Canadian RO residents and to inform Canadian RO residency training...

INTRODUCTION: Post-sepsis cognitive impairment is one of the major sequelae observed in survivors of sepsis. This cognitive impairment can be global or may affect specific domains. A better understanding of these deficits and associated risk factors could influence the care of patients with sepsis. OBJECTIVE: To perform a systematic review to investigate the presence of cognitive impairment and its associated risk factors among patients who survived sepsis. METHODS: The search was conducted in MEDLINE (1966 to March 2017) and EMBASE (1988 to March 2017)...

Background: Malignant glioma (MG) is a devastating neuro-oncologic disease with almost invariably poor prognosis. Prognostic awareness (PA) is the awareness of incurable disease and shortened life-expectancy (LE). Accurate PA is associated with favorable psychological outcomes at the end-of-life (EOL) for patients with cancer, however little is known about PA or prognostic communication in MG. Moreover, research has yet to evaluate the impact of cognitive impairment on PA and preferred forms of communication...

Study Objectives: REM sleep behavior disorder (RBD) is a parasomnia affecting 33 to 46% of patients with Parkinson's disease (PD). The existence of a unique and specific impaired cognitive profile in PD patients with RBD is still controversial. We extensively assessed cognitive functions to identify whether RBD is associated with more severe cognitive deficits in nondemented patients with PD. Methods: One hundred and sixty-two participants, including 53 PD patients with RBD, 40 PD patients without RBD, and 69 healthy subjects, underwent polysomnography, a neurological assessment, and an extensive neuropsychological exam to assess attention, executive functions, episodic learning and memory, visuospatial abilities, and language...

The benefits of sleep on memory consolidation have been enhanced for declarative and motor sequence learning through replaying classically conditioned auditory stimuli during sleep, known as targeted memory reactivation (TMR). However, it is unknown if TMR can influence performance of a sensorimotor skill, in the absence of the cognitive requirements of sequence learning. Here, young adults performed a nondominant arm throwing task separated by a full night of sleep or a full day of wake, with half of all participants receiving TMR between sessions...
