Moving beyond standard procedures to assess spontaneous recognition memory
نویسندگان
چکیده
This review will consider how spontaneous tasks have been applied alongside neuroscientific techniques to test complex forms of recognition memory for objects and their environmental features, e.g. the spatial location of an object or the context in which it is presented. We discuss studies that investigate the roles of the perirhinal cortex and the hippocampus in recognition memory using standard testing paradigms, and consider how these findings contribute to the ongoing debate about whether recognition memory is a single unitary process or multiple processes that can be dissociated anatomically and functionally. Due to the wide use of spontaneous tasks, the need for improved procedures that reduce animal use is acknowledged, with multiple trial paradigms discussed as a novel way of reducing variability and animal numbers in these tasks. The importance of improving translation of animal models to humans is highlighted, with emphasis on a shift away from relying on the phenomenological experience of human subjects.

A new behavioural apparatus to reduce animal numbers in multiple types of spontaneous object recognition paradigms in rats
Standard object recognition procedures assess animals' memory through their spontaneous exploration of novel objects or novel configurations of objects with other aspects of their environment. Such tasks are widely used in memory research, but also in pharmaceutical companies screening new drug treatments. However, behaviour in these tasks may be driven by influences other than novelty such as ...
متن کاملAn associative analysis of object memory
Different aspects of recognition memory in rodents are commonly assessed using variants of the spontaneous object recognition procedure in which animals explore objects that differ in terms of their novelty, recency, or where they have previously been presented. The present article describes three standard variants of this procedure, and outlines a theory of associative learning, SOP which can ...

Background: Most studies have investigated the effect of brain pathological aging on information recall and recognition memory performance of patients (by using a yes/no procedure), and for this reason, provide a partial picture of memory deficits and other factors involved in recognition memory such as discriminability and response bias are not considered. In this regard, the aim of present st...
متن کاملMoving beyond the ‘beads-on-a-string’ Model of Speech
The notion that a word is composed of a sequence of phone segments, sometimes referred to as ‘beads on a string’, has formed the basis of most speech recognition work for over 15 years. However, as more researchers tackle spontaneous speech recognition tasks, that view is being called into question. This paper raises problems with the phoneme as the basic subword unit in speech recognition, sug...
