Males of the hornyhead chub Nocomis biguttatus, 90 mm (3.5 in) long, and of the river chub Nocomis micropogon, 100 mm (3.9 in) long, also build mounds during the reproductive season. They start by clearing a slight depression in the substrate, which they overfill with up to 10,000 pebbles until the mounds are 60–90 cm (2.0–3.0 ft) long (in ...
Goldfish that have constant visual contact with humans also stop considering them to be a threat. After being kept in a tank for several weeks, sometimes months, it becomes possible to feed a goldfish by hand without it shying away. Goldfish have a memory-span of at least three months and can distinguish between different shapes, colors, and ...
Long-term memory (LTM) is the stage of the Atkinson–Shiffrin memory model in which informative knowledge is held indefinitely. It is defined in contrast to sensory memory, the initial stage, and short-term or working memory, the second stage, which persists for about 18 to 30 seconds.
Although brain size doesn’t necessarily indicate more brain power, elephants have an incredible memory because their cerebral cortex is so big. This is the brain area that stores long-term memories.
Memory has been widely investigated in foraging honeybees, Apis mellifera, which use both transient short-term working memory that is non-feeder specific and a feeder specific long-term reference memory. [58] [59] [60] Memory induced in a free-flying honeybee by a single learning trial lasts for days and, by three learning trials, for a ...
Short-term memory has limited capacity and is often referred to as "working-memory", however these are not the same. Working memory involves a different part of the brain and allows you to manipulate it after initial storage. The information that travels from sensory memory to short-term memory must pass through the Attention gateway. The ...
Studies have shown that short-term memory and long-term memory are two distinct processes that emphasize different levels of activation in the brain among different cortical areas. Furthermore, the rate of decay is much faster in short-term memory as opposed to long-term memory. The OSCAR model in particular does not account for this phenomenon.
The forgetting curve hypothesizes the decline of memory retention in time. This curve shows how information is lost over time when there is no attempt to retain it. [1] A related concept is the strength of memory that refers to the durability that memory traces in the brain. The stronger the memory, the longer period of time that a person is ...
