Nålebinding-History-Nålbinding predates knitting and crochet. Historical samples have often been misidentified as knitting due to how similar they can appear in the finished products if made using the Coptic stitch. Often a textile historian will need to closely follow the path of the yarn itself to identify the item a... | milkshake721/2.1M-wiki-STEM |
Nålebinding-History-Nålbinding was used during the Viking age of 793–1066 CE in Scandinavia before knitting and crochet were known. This was an effective method for them to create sturdy, serviceable garments.

Nålebinding-History-The term "nålebinding" was introduced in the 1970s.A famous piece of nålbinding is the 'Coppergate sock' found during an excavation of the Coppergate area of York.

Nålebinding-History-Nålbinding was used in some regions of Northern Europe until the 1950s, when it most likely declined because of the changes in the textile industry and almost disappeared. It later gained renewed interest among many textile historians, archaeologists, craftspeople and reenactors, so that it is today... | milkshake721/2.1M-wiki-STEM |
Nålebinding-Technique-The method creates an elastic fabric using short lengths of yarn and a single-eyed needle that is often broad and flat. The stitches are commonly, but not invariably, gauged by wrapping them around the thumb. In its simplest form, the needle is passed through a seed loop to form a new loop, taking... | milkshake721/2.1M-wiki-STEM |
Nålebinding-Technique-Crafters nowadays often use a specialised notation called the Hansen code to create patterns and communicate about the nålebinding technique. This code has been developed in 1990 by Egon Hansen, an expert on textile reconstruction who worked at the Moesgård Museum in Denmark. | milkshake721/2.1M-wiki-STEM |
Nålebinding-Technique-The Hansen code is a coding system used to indicate the path of the needle as it is worked through the preexisting fabric, with its passage under a loop shown as U and over a loop as O. A slash shows where the yarn changes direction and returns through loops it has already passed. If a loop is ski... | milkshake721/2.1M-wiki-STEM |
Nålebinding-Characteristics-Nålebinding is often called more laborious and slower than knitting. This is not necessarily true, especially for the simpler stitches, such as the Oslo-, Mammen- and Brodén-stitches.

Involuntary memory-History-Marcel Proust—Proustian memory Marcel Proust was the first person to coin the term involuntary memory, in his novel À la recherche du temps perdu (In Search of Lost Time or Remembrance of Things Past). Proust did not have any psychological background, and worked primarily as a writer. | milkshake721/2.1M-wiki-STEM |
Involuntary memory-History-Proust viewed involuntary memory as containing the "essence of the past," claiming that it was lacking from voluntary memory.

Involuntary memory-Current research-Priming A common question in the study of involuntary memory is related to priming; what is it that activates such a memory? Various studies have been conducted in recent years to observe the conditions under which involuntary memories are primed. | milkshake721/2.1M-wiki-STEM |
Involuntary memory-Current research-Mace, in one of his recent studies, wanted to test the notion that basic cognitive activities, such as thinking about the past, may prime involuntary memories. To test this idea, Mace set up a diary method study in which participants recorded involuntary memories they experienced dur... | milkshake721/2.1M-wiki-STEM |
Involuntary memory-Neurological basis-Research studies regarding the neurological functions of involuntary memory have been few in number. Thus far, only two neuroimaging studies have been conducted comparing involuntary memories to voluntary memories using Positron Emission Tomography (PET). | milkshake721/2.1M-wiki-STEM |
Involuntary memory-Neurological basis-The first study found that while involuntary memory retrieval is mediated by the hippocampus, a structure of the brain known to be associated with successful episodic memory retrieval, involvement of the hippocampus was independent of whether or not remembering was intentional.

Involuntary memory-Neurological basis-The second study found that the medial temporal lobe, the posterior cingulate gyrus, and the precuneus, are activated during retrieval success with or without executive control seen within the right dorsolateral prefrontal cortex. This implies that involuntary memories are successf... | milkshake721/2.1M-wiki-STEM |
Involuntary memory-Effects of age-Development While age plays a role in memory capabilities, it has been found that general strategies used to encode (to remember) memories is more important.
