Stimulus variation and sequential judgements of duration

When a series of reproductions of an interval is made in the absence of a standard the judgements progressively lengthen. The similarity between stimulus conditions in this type of time estimation experiment and the conditions which produce a decrement in human vigilance is discussed. It is argued that failure to detect cues for the passage of time reduces the amount of time perceived to elapse. Reproduced judgements must consequently be increased in length to match remembered standards. The hypothesis is then made that the kind of variation in background stimulation which facilitates vigilance should increase the frequency of detection of cues for duration and reduce reproduced judgements. This hypothesis is tested with 80 subjects and a reversal of the serial reproduction effect is found on trials with changed background conditions.

Multidisciplinarity and cognitive science

The aim of Schunn, Crowley and Okada's (1998) study is to address the question of whether the current state of cognitive science, as represented by Cognitive Science and the Cognitive Science Society, “reflects the multidisciplinary ideals of its foundation.” To properly interpret and respond to their results, we need to ask a prior question: What is cognitive science's multidisciplinary ideal? There are at least two conceptions—a “localist” conception, which seems to be implicit in Schunn, Crowley and Okada's discussion, and a “holist” conception. I argue that while both have been endorsed by some cognitive scientists, there are reasons for preferring the holist conception. I then consider what Schunn, Crowley and Okada's findings tell us about the state of cognitive science in light of a holist approach and report on an analysis of the journal's contents which looks at the domain, subdomain, and cognitive capacity investigated.     

The Role of Attachment and Maladaptive Emotion Regulation Strategies in the Development of Bulimic Symptoms in Adolescents

Following the theoretical propositions of the Emotion Regulation model of attachment, the current study investigated whether attachment anxiety and attachment avoidance might play a differential contributing role in the development of bulimic symptoms, through assumed differences in adopting specific maladaptive emotion regulation strategies in a sample of adolescents. Developmentally appropriate self-report questionnaires were administered to a community sample of 397 adolescents (Mean age: 14.02; 62.7% female) and this at 2 time points with a 1-year time lag. Results provided longitudinal evidence for the Emotion Regulation model of attachment in confirming the differential contributing role of the attachment dimensions on the development of bulimic symptoms in a sample of adolescents. More specifically, attachment anxiety seemed to be related to bulimic symptoms through rumination, while attachment avoidance through emotional control. These results may have clinical implications for assessment and treatment of bulimic symptoms in adolescents.     

<Emphasis Type="Italic">Doctor Anonymous</Emphasis>: Creating Contexts for Homosexuality as Mental Illness

In this essay, the author describes how he faced institutionalized homophobia during his psychiatric training, and how he later wrote a play inspired by the life of a gay psychiatrist. Despite Freud’s supportive stance, homosexuality aroused the antipathy of American organized psychiatry and psychoanalysis and came to be listed as an illness in the Diagnostic and Statistical Manual (DSM). Dr. John E. Fryer outed himself as “Dr. H Anonymous” at a 1972 meeting of the American Psychiatric Association, and the next year homosexuality was removed from the DSM. The 2014 play Doctor Anonymous offers a fictionalized account of this watershed moment in the history of the gay rights movement. The author discusses his own psychotherapeutic work with gay male patients, including those who had previously been treated with conversion therapy, and explores how the play mirrors his own life experience and the experience of his patients.     

Concurrent Cortical Representations of Function- and Size-Related Object Affordances: An fMRI Study

Previous work has shown that the perception of a graspable object may automatically potentiate actions that are tailored to specific action-related features of the object (e.g., its size) and may be related to its immediate grasping as well as to its long-term, functional use. We investigated the neural correlates of function- and size-related object affordances that may be concurrently potentiated by a graspable object. Participants were lying in a MR scanner holding a large switch in one hand and a small switch in the other hand. They passively attended a large or a small object with clearly separated functional and graspable end that was displayed centrally at an average angle of 45 degrees. Participants responded to the direction of an arrow that was overlaid on the object after a mean period of 1,000 ms after object onset and was pointing to the left or to the right with equal probability. Response times were shorter when the arrow pointed to the functional end of the object and when the responses were made with the switch that was congruent to the size of the perceived object. A clear distinction was found in the representation of function- and size-related affordances; the former was represented in the posterior parietal cortex and the latter in prefrontal, premotor, and primary sensorimotor cortices. We conclude that different aspects of object-directed actions may be automatically potentiated by individual object features and are represented in distinct brain areas.
