Quantitative evidence for distinct cognitive impairment in anorexia nervosa and bulimia nervosa

It is generally agreed that at least some aspects of abnormal eating behaviour is indeed due in part to disordered cognition. The accumulated literature illustrates cognitive impairment in patients with anorexia nervosa (AN) and bulimia nervosa (BN). Yet beyond being inconsistent, these independent studies also do not reveal the magnitude of impairment within and across studies and fail to give due consideration to the magnitude of impairment so as to understand the severity and breadth of impairment and/or differences in cognitive profiles between patients with AN and BN. Hence, the present review on the subject sought to articulate the magnitude of cognitive impairment in patients with AN and BN by quantitatively synthesizing the existing literature using meta-analytic methodology. The results demonstrate modest evidence of cognitive impairment specific to AN and BN that is related to body mass index in AN in terms of its severity, and is differentially impaired between disorders. Together, these results suggest that disturbed cognition is figural in the presentation of eating disorders and may serve to play an integral role in its cause and maintenance. Implications of these findings with respects to future research are discussed.

Phonological dyslexia and dysgraphia in a highly literate subject: A developmental case with associated deficits of phonemic processing and awareness

This paper describes some aspects of reading and writing in a highly literate subject who has unusual difficulty in reading and spelling non-words. No cerebral trauma is indicated, and she performs at above average levels on standard tests of reading, spelling and cognitive ability. Only digit span is significantly impaired. Although auditory phoneme discrimination is normal, she performs poorly on aural tasks, like rhyme judgement and homophone matching, that require awareness of phonemic structure, and she is impaired at segmenting heard words into their component sounds.

Tests of immediate memory confirm abnormal span and indicate a failure to use normal phonological coding in immediate recall. We argue that a deficit in phonological processing underlies impaired performance on tasks of reading, spelling and immediate memory.     

Capturing Situational Information with Smartphones and Mobile Sensing Methods

Smartphones are pervasive companions to many people as they go about their daily lives. In addition, they are equipped with a wide array of sensors making it possible to measure objective information about people and situations, many times, with great fidelity, over long periods of time, in a way that is both unobtrusive and ecologically valid. Therefore, we argue that smartphones and other forms of mobile sensing are ideally suited to measuring situations. In particular, we describe how sensing methods can be used to assess situational cues, characteristics and classes. Copyright © 2015 European Association of Personality Psychology     

Changing the Legacy of Suicide

In the United States, despite the increase in knowledge about suicide, the rate of suicide has remained virtually unchanged for the past 30 years. The members of the American Association of Suicidology (AAS) are uniquely qualified to determine what, if anything, can be done to reduce the rate of suicide. The restructuring of the association has produced the potential for cross-divisional collaboration, and yet conventional membership boundaries have resulted in unrealized opportunities to impact the rate of suicide. Dr. Edwin Shneidman, stated in Albert Cain's 1972 landmark book Survivors of Suicide that “post-vention is prevention for the next generation” (p. x). The ability to design, implement, and study an effective model of postvention is within the considerable talents of our membership; however, doing so will require the commitment and flexibility of the entire association. By making postvention collaboration a goal of the association we can bring a national focus on suicide that could change the legacy of suicide.     

Dissociating Face Processing Skills: Decisions about Lip read Speech, Expression, and Identity

The separability of different subcomponents of face processing has been regularly affirmed, but not always so clearly demonstrated. In particular, the ability to extract speech from faces (lip-reading) has been shown to dissociate doubly from face identification in neurological but not in other populations. In this series of experiments with undergraduates, the classification of speech sounds (lip-reading) from personally familiar and unfamiliar face photographs was explored using speeded manual responses. The independence of lip-reading from identitybased processing was confirmed. Furthermore, the established pattern of independence of expression-matching from, and dependence of identity-matching on, face familiarity was extended to personally familiar faces and 'difficult'-emotion decisions. The implications of these findings are discussed.
