The construct of "memory" in this example represents an intervening variable, as it is believed to exist between the presentation time and the later recall of words. It is not the independent or dependent variable, as those are the manipulated variable (amount of time viewing the words) and the measured outcome (number of words recalled), respectively. It is also not an operational definition, as that is a specific way of measuring a construct or variable.
