Structuralist heroes and points of heresy: recognizing Gilles Deleuze’s (anti-)structuralism

Continental Philosophy Review - This article is concerned with the status and stakes of Gilles Deleuze’s “break” with structuralism. With a particular focus on a transitional text...     

The consequence of a limited-capacity short-term memory on repeated visual search

ABSTRACT

When participants search the same letter display repeatedly for different targets we might expect performance to improve on each subsequent search as they memorize characteristics of the display. However, here we find that search performance improved from a first search to a second search but not for a third search of the same display. This is predicted by a simple model that supports search with only a limited capacity short-term memory for items in the display. To support this model we show that a short-term memory recency effect is present in both the second and the third search. The magnitude of these effects is the same in both searches and as a result there is no additional benefit from the second to the third search.     

Is there a duty to remain in ignorance?

Questions about information inform many debates in bioethics. One of the reasons for this is that at least some level of information is taken by many to be a prerequisite of valid consent. For others, autonomy in the widest sense presupposes information, because one cannot be in control of one’s life without at least some insight into what it could turn out to contain. Yet not everyone shares this view, and there is a debate about whether or not there is a right to remain in ignorance of one’s medical, and especially genetic, information. It is notable, though, that this debate leaves unexamined the assumption that, if a person wants information, he is entitled to it. This paper examines the assumption, specifically in relation to genetics, where learning facts about oneself may reveal facts about other people, particularly one’s close relatives. This may be taken as a violation of their privacy, and since privacy is something that we normally think should be respected, it is worth asking whether one ought to abjure the opportunity to obtain genetic information for the sake of privacy. In effect, there may be an argument to be made not just for a right to remain in ignorance, but for a duty to do so.     

Discriminating famous from fictional names based on lifetime experience: evidence in support of a signal-detection model based on finite mixture distributions

It is widely accepted that signal-detection mechanisms contribute to item-recognition memory decisions that involve discriminations between targets and lures based on a controlled laboratory study episode. Here, the authors employed mathematical modeling of receiver operating characteristics (ROC) to determine whether and how a signal-detection mechanism contributes to discriminations between moderately famous and fictional names based on lifetime experience. Unique to fame judgments is a lack of control over participants' previous exposure to the stimuli deemed "targets" by the experimenter; specifically, if they pertain to moderately famous individuals, participants may have had no prior exposure to a substantial proportion of the famous names presented. The authors adopted established models from the recognition-memory literature to examine the quantitative fit that could be obtained through the inclusion of signal-detection and threshold mechanisms for two data sets. They first established that a signal-detection process operating on graded evidence is critical to account for the fame judgment data they collected. They then determined whether the graded memory evidence for famous names would best be described with one distribution with greater variance than that for the fictional names, or with two finite mixture distributions for famous names that correspond to items with or without prior exposure, respectively. Analyses revealed that a model that included a d' parameter, as well as a mixture parameter, provided the best compromise between number of parameters and quantitative fit. Additional comparisons between this equal-variance signal-detection mixture model and a dual-process model, which included a high-threshold process in addition to a signal-detection process, also favored the former model. In support of the conjecture that the mixture parameter captures participants' prior experience, the authors found that it was increased when the analysis was restricted to names in occupational categories for which participants indicated high exposure.     

South Korean culture and history: The implications for workplace bullying

This paper began by suggesting that culture might influence how people construe workplace bullying. Referring back to the studies of cultural differences in cognition, it was suggested that people of the Far East might construe workplace bullying differently from the people of Western countries. Taking South Korean culture as an example, this paper explained how historical background and culture shaped Korean's psyche in relation to workplace bullying. Currently available evidence was discussed including the way Koreans construed workplace bullying and how close social bonding might act as a buffer against a conflict escalating into bullying.
