Current scientific interest in dissociative amnesia: A bibliometric analysis

In a bibliometric analysis, we used the PubMed search engine to count the number of publications identified by the search term “dissociative amnesia” for the years 2011–2020. We then counted publications from the same decade for five representative comparison disorders: “panic disorder,” “anorexia nervosa,” “obsessive–compulsive disorder,” “attention deficit hyperactivity disorder,” and “bipolar disorder.” Our search yielded only 89 publications for “dissociative amnesia,” and only seven of these involved localized or selective amnesia for specific events. By contrast, we found between 3000 and 21,000 publications for each of the five comparison disorders during 2011–2020. We performed several additional secondary analyses, all of which suggested that the diagnosis of “localized or selective dissociative amnesia” has generated little scientific interest in recent years. Examining possible hypotheses to explain this lack of interest, it appears most likely that the concept of localized or selective dissociative amnesia is not widely accepted among scientists at present.     

Victor Frankenstein’s Institutional Review Board Proposal, 1790

To show how the case of Mary Shelley’s Victor Frankenstein brings light to the ethical and moral issues raised in Institutional Review Board (IRB) protocols, we nest an imaginary IRB proposal dated August 1790 by Victor Frankenstein within a discussion of the importance and function of the IRB. Considering the world of science as would have appeared in 1790 when Victor was a student at Ingolstadt, we offer a schematic overview of a fecund moment when advances in comparative anatomy, medical experimentation and theories of life involving animalcules and animal electricity sparked intensive debates about the basic principles of life and the relationship between body and soul. Constructing an IRB application based upon myriad speculations circulating up to 1790, we imagine how Victor would have drawn upon his contemporaries’ scientific work to justify the feasibility of his project, as well as how he might have outlined the ethical implications of his plan to animate life from “dead” tissues. In Mary Shelley’s Frankenstein, Victor failed to consider his creature’s autonomy, vulnerability, and welfare. In this IRB proposal, we show Victor facing those issues of justice and emphasize how the novel can be an important component in courses or workshops on research ethics. Had Victor Frankenstein had to submit an IRB proposal tragedy may have been averted, for he would have been compelled to consider the consequences of his experiment and acknowledge, if not fulfill, his concomitant responsibilities to the creature that he abandoned and left to fend for itself.     

Views of a good life and allostatic load: Physiological correlates of theories of a good life depend on the socioeconomic context

This research examines the relationship between one’s theory of a good life and allostatic load, a marker of cumulative biological risk, and how this relationship differs by socioeconomic status. Among adults with a bachelor’s degree or higher, those who saw individual characteristics (e.g. personal happiness, effort) as part of a good life had lower levels of allostatic load than those who did not. In contrast, among adults with less than a bachelor’s degree, those who saw supportive relationships as part of a good life had lower levels of allostatic load than those who did not. These findings extend past research on socioeconomic differences in the emphasis on individual or relational factors and suggest that one’s theory of a good life has health implications.     

Knowing that strawberries are red and seeing red strawberries: the interaction between surface colour and colour knowledge information

This study investigates the interaction between surface and colour knowledge information during object recognition. In two different experiments, participants were instructed to decide whether two presented stimuli belonged to the same object identity. On the non-matching trials, we manipulated the shape and colour knowledge information activated by the two stimuli by creating four different stimulus pairs: (1) similar in shape and colour (e.g. TOMATO–APPLE); (2) similar in shape and dissimilar in colour (e.g. TOMATO–COCONUT); (3) dissimilar in shape and similar in colour (e.g. TOMATO–CHILI PEPPER) and (4) dissimilar in both shape and colour (e.g. TOMATO–PEANUT). The object pictures were presented in typical and atypical colours and also in black-and-white. The interaction between surface and colour knowledge showed to be contingent upon shape information: while colour knowledge is more important for recognising structurally similar shaped objects, surface colour is more prominent for recognising structurally dissimilar shaped objects.     

Evaluating a humane alternative to the bark collar: Automated differential reinforcement of not barking in a home‐alone setting

The aim of this study was to develop a humane alternative to the traditional remote devices that deliver punishers contingent on home‐alone dog barking. Specifically, we evaluated the use of remote delivery of food contingent on intervals of not barking during the pet owner's absence. In Experiment 1, 5 dogs with a history of home‐alone nuisance barking were recruited. Using an ABAB reversal design, we demonstrated that contingent remote delivery of food decreased home‐alone barking for 3 of the dogs. In Experiment 2, we demonstrated that it is possible to thin the differential‐reinforcement‐of‐other‐behavior (DRO) schedule gradually, resulting in a potentially more acceptable treatment. Our results benefit the dog training community by providing a humane tool to combat nuisance barking.
