Abstract

A mathematical model of a memory trace and forgetfulness is proposed here based on an improved version of our previous work (Harth et al., 1970; Anninos et al., 1970). Thus it was shown that the trace of a stimulus pattern presented to a subject decays with time due to the interference theory which assumes that competition among different associations leads to losses of retention. Such interference theory has been tested in this model by assuming that the retention of a first ...

Abstract

Users gain access to cash, confidential information and services at Automated Teller Machines (ATMs) via an authentication process involving a Personal Identification Number (PIN). These users frequently have many different PINs, and fail to remember them without recourse to insecure behaviours. This is not a failing of users. It is a usability failing in the ATM authentication mechanism. This paper describes research executed to evaluate whether users find multiple graphical passwords more memorable than multiple PINs. The research also investigates the ...

Abstract

While it is well known that repetition can enhance memory in amnesia, little is known about which forms of repetition are most beneficial. This study compared the effect on recognition memory of repetition of words in the same semantic context and in varied semantic contexts. To gain insight into the mechanisms by which these forms of repetition affect performance, participants were asked to make Remember/Know judgments during recognition. These judgments were used to make inferences about the contribution of recollection and ...
