Euthymic bipolar disorder (BD) has been associated with subtle impairment in face processing. However, it is not known whether their difficulties extend to the processing of gaze. In the present study, two tasks, both of which rely on the ability to make use of the eye region of a pictured face, were used: the Reading the Mind in the Eyes test and the Eye-gaze cueing task. Compared to healthy controls, BD patients were impaired at judging mental state from images of the face but showed normal susceptibility to the direction of gaze as an attentional cue. These findings suggest that BD patients present selective gaze processing impairment, limited to the sensitivity to intention and emotion. This impairment could account at least partially for the higher levels of interpersonal problems generally observed in BD.

BackgroundBorderline personality disorder (BPD) is partly characterized by chronic instability in interpersonal relationships, which exacerbates other symptom dimensions of the disorder and can interfere with treatment engagement. Facial emotion recognition paradigms have been used to investigate the bases of interpersonal impairments in BPD, yielding mixed results. We sought to clarify and extend past findings by using the Reading the Mind in the Eyes Test (RMET), a measure of the capacity to discriminate the mental state of others from expressions in the eye region of the face.MethodThirty individuals diagnosed with BPD were compared to 25 healthy controls (HCs) on RMET performance. Participants were also assessed for depression severity, emotional state at the time of assessment, history of childhood abuse, and other Axis I and personality disorders (PDs).ResultsThe BPD group performed significantly better than the HC group on the RMET, particularly for the Total Score and Neutral emotional valences. Effect sizes were in the large range for the Total Score and for Neutral RMET performance. The results could not be accounted for by demographics, co-occurring Axis I or II conditions, medication status, abuse history, or emotional state. However, depression severity partially mediated the relationship between RMET and BPD status.ConclusionsMental state discrimination based on the eye region of the face is enhanced in BPD. An enhanced sensitivity to the mental states of others may be a basis for the social impairments in BPD.

Objectives: Impaired social cognition in bipolar disorder (BD) is related to functional outcomes. A critical determinant of social cognition is the ability to discriminate the eye gaze direction of others, and its alteration may play a role in functional impairment in BD. However, the neural mechanisms underlying gaze processing in BD are unclear. Because neural oscillations and their communications through inter-region synchronization are crucial neurobiological mechanisms that support cognition, this study aimed to understand their role in gaze processing in BD.Methods: Electroencephalography (EEG) was recorded during a gaze discrimination task for 38 participants with BD and 34 healthy controls (HC). Time-frequency decomposition of EEG data was used to examine: 1) neural oscillatory power at bilateral parietal and midline frontal locations associated with face processing and higher-level cognition, and 2) feedforward and feedback connectivity between sites via theta-gamma phase-amplitude coupling (PAC).Results: Compared to HC, BD showed reduced theta power at the left parietal and midline frontal sites. BD also showed reduced PAC between bilateral parietal and midline frontal sites. Reduced theta power and PAC were related to poorer gaze discrimination task performance across participants.Conclusions: Altered theta power and feedforward/feedback connectivity between face-processing and midline frontal brain areas may underlie abnormal gaze processing in BD.

The Face

Children with Rett Syndrome (RS) are reported to use multiple modalities to communicate although their intentionality is often questioned (Bartolotta, Zipp, Simpkins, & Glazewski, 2011; Hetzroni & Rubin, 2006; Sigafoos et al., 2000; Sigafoos, Woodyatt, Tuckeer, Roberts-Pennell, & Pittendreigh, 2000). This paper will present results of a study analyzing the unconventional vocalizations of a child with RS. The primary research question addresses the ability of familiar and unfamiliar listeners to interpret unconventional vocalizations as “yes” or “no” responses. This paper will also address the acoustic analysis and perceptual judgments of these vocalizations. Pre-recorded isolated vocalizations of “yes” and “no” were presented to 5 listeners (mother, father, 1 unfamiliar, and 2 familiar clinicians) and the listeners were asked to rate the vocalizations as either “yes” or “no.” The ratings were compared to the original identification made by the child's mother during the face-to-face interaction from which the samples were drawn. Findings of this study suggest, in this case, the child's vocalizations were intentional and could be interpreted by familiar and unfamiliar listeners as either “yes” or “no” without contextual or visual cues. The results suggest that communication partners should be trained to attend to eye-gaze and vocalizations to ensure the child's intended choice is accurately understood.

Configural processing has been considered the major contributor to the face inversion effect (FIE) in face recognition. However, most researchers have only obtained the FIE with one specific ratio of configural alteration. It remains unclear whether the ratio of configural alteration itself can mediate the occurrence of the FIE. We aimed to clarify this issue by manipulating the configural information parametrically using six different ratios, ranging from 4% to 24%. Participants were asked to judge whether a pair of faces were entirely identical or different. The paired faces that were to be compared were presented either simultaneously (Experiment 1) or sequentially (Experiment 2). Both experiments revealed that the FIE was observed only when the ratio of configural alteration was in the intermediate range. These results indicate that even though the FIE has been frequently adopted as an index to examine the underlying mechanism of face processing, the emergence of the FIE is not robust with any configural alteration but dependent on the ratio of configural alteration.

David Hoinski and Ronald Polansky’s “The Modern Aristotle: Michael Polanyi’s Search for Truth against Nihilism” shows how the general tendencies of contemporary philosophy of science disclose a return to the Aristotelian emphasis on both the formation of dispositions to know and the role of the mind in theoretical science. Focusing on a comparison of Michael Polanyi and Aristotle, Hoinski and Polansky investigate to what degree Aristotelian thought retains its purchase on reality in the face of the changes wrought by modern science. Polanyi’s approach relies on several Aristotelian assumptions, including the naturalness of the human desire to know, the institutional and personal basis for the accumulation of knowledge, and the endorsement of realism against objectivism. Hoinski and Polansky emphasize the promise of Polanyi’s neo-Aristotelian framework, which argues that science is won through reflection on reality.

AbstractThe authors tested face discrimination, face recognition, object discrimination, and object recognition in two face transplantation patients (FTPs) who had facial injury since infancy, a patient who had a facial surgery due to a recent wound, and two control subjects. In Experiment 1, the authors showed them original faces and morphed forms of those faces and asked them to rate the similarity between the two. In Experiment 2, they showed old, new, and implicit faces and asked whether they recognized them or not. In Experiment 3, they showed them original objects and morphed forms of those objects and asked them to rate the similarity between the two. In Experiment 4, they showed old, new, and implicit objects and asked whether they recognized them or not. Object discrimination and object recognition performance did not differ between the FTPs and the controls. However, the face discrimination performance of FTP2 and face recognition performance of the FTP1 were poorer than that of the controls were. Therefore, the authors concluded that the structure of the face might affect face processing.

Don't philosophers die just like all other men? In order to speak of the death of philosophers, why choose an author like Boureau-Deslandes, who collected anecdotes of insolence in the face of death? Undoubtedly, free minds could only disarm theology by joking about it. The mental, moral and playful mechanisms of the mind can be taken apart to reveal the bans inscribed in the conscience through the workings of institutions. Against the philosophies of melancholy, fear, death and power, a philosophy of banter is a cheerful philosophy, an ethics of taste that destabilises the rules. It is this practice of bantering insolence that turns temperament into virtue and a man into a philosopher.

“The knowledge concerning the sympathies and concordances between the mind and the body” saith the founder† of modern science, in discoursing of human philosophy, or the knowledge of ourselves, as he terms it, is “fit to be emancipate and made a knowledge by itself. The consideration is double: either how and how far the humours and effects of the body do alter or work upon the mind; or again, how and how far the passions and apprehensions of the mind do alter or work upon the body. The former of these,” (the influence of the body on the mental state,) continues Bacon, “hath been enquired and considered as a part and appendix of medicine, but much more as a part of religion or superstition. For the physician prescribeth cures of the mind in phrensies and melancholy passions; and pretendeth also to exhibit medicines to exhilarate the mind, to confirm the courage, to clarify the wits, to corroborate the memory and the like: but the scruples and superstitions of diet and other regimen of the body in the sect of Pythagoreans, in the heresy of the Manicheans, and in the law of Mahomet do exceed. … The root and life of all which prescripts is besides the ceremony, the consideration of that dependency, which the affections of the mind are submitted unto, upon the state and disposition of the body.”
