Sample size (the number of individuals examined for a study) is the most important factor determining the accuracy of the study results.
New research from Northwestern University reveals that infants can use even a few labeled examples to spark the acquisition of object categories. Those labeled examples lead infants to initiate the process of categorization, after which they can integrate all subsequent objects, labeled or unlabeled, into their evolving category representation.
A recently published study shows that unless they speak in a confident tone of voice, you're less likely to believe someone who speaks with an accent. And, interestingly, as you make this decision different parts of your brain are activated, depending on whether you perceive the speaker to be from your own 'in-group' or from some type of 'out-group' (e.g., someone with a different linguistic or cultural background).
'Cannot get asleep all night', 'a little giddy' and other complaints in social networks can now be translated into formal medical terms, such as insomnia or vertigo. The task of comparing syndromes mentioned by patients and specific medical terms is called the normalization of medical concepts.
Lad culture in English universities is often perceived by university staff as involving 'extreme' behaviour and as being carried out by only a handful of 'bad apples' rather than as a widespread culture that fosters gender-based harassment and violence. But new research, led by Lancaster University, says this perception stems from various factors, including many staff having limited understandings of lad culture which reflect the way it is portrayed in the media.
For thousands of years, humans have relied on storytelling to engage, to share emotions and to relate personal experiences. Now, psychologists at McMaster University are exploring the mechanisms deep within the brain to better understand just what happens when we communicate.
The earliest evidence of a drawing made by humans has been found in Blombos Cave in the southern Cape in South Africa. The drawing, which consists of three red lines cross-hatched with six separate lines, was intentionally drawn on a smooth silcrete flake about 73,000 years ago. This predates previous drawing from Africa, Europe and Southeast Asia by at least 30,000 years.
In an article published online on Aug. 20, 2018 by the Journal of the American Medical Association Neurology, researchers tested the use of transcranial direct current stimulation in stroke patients with aphasia. Their results justify the creation of a large clinical trial to test the new treatment in a number of patients who have lost some or all of their use of language after stroke.
The speed at which someone speaks influences the way we hear upcoming words. But, until recently, little was known about the neural mechanisms behind this phenomenon. A recent study involving researchers from the Max Plank Institute for Psycholinguistics (MPI) reveals that our brainwaves synchronize to the speech rate, thereby influencing how we hear and perceive words.
Neuroscientists at the University of Pennsylvania and the U.S. Army Research Laboratory have forecasted what content will get passed along repeatedly.
