Anorexia nervosa and brain tumor in a 14-year-old girl

A 14-year-old girl with anorexia nervosa (AN) was found to have an intracranial neoplasm. Atypical psychological symptoms prompted further evaluation, including electroencephalogram and neuroimaging, which revealed a sellar and suprasellar mass. This patient had an eating disorder and a brain tumor, which appear to be two unrelated conditions. However, it remains unclear how each affected the other. The diagnosis of AN, like all other psychiatric disorders, requires that possible medical etiologies and coexisting medical problems be excluded. AN and other eating disorders are particularly difficult to diagnose in children and adolescents because they often do not present in the manner typical of adults. Perceptual and cognitive disturbances associated with AN are difficult to evaluate because children and adolescents normally change over time as they progress through different stages of development. Therefore, it is particularly important to evaluate for the presence of medical conditions when a diagnosis of an eating disorder is made in a child or adolescent.     

Making an Art of Creativity: The Cognitive Science of Duchamp and Dada

Dada is the infant terrible of art history, an anarchic movement that is typically referred to as nihilistic, pathological, and firmly enshrined within the modernist paradigm and the context of WWI. Through the lens of classical, romantic, and psychoanalytic notions, it certainly appears almost antithetical to creativity. Yet from a cognitive point-of-view, Dada marks a watershed in the understanding of creativity, and articulates principles of creative cognition with surprising insight and precision many decades ahead of science.     

The Multigenerational Transmission of Family Unit Functioning

Abstract

Bowen theory hypothesizes that a nuclear family's level of functioning is influenced by the stability or functioning of previous generations. This longitudinal study tested this hypothesis with 49 newly developing nuclear families and their multigenerational families. Family functioning was measured using a composite of physical, emotional, social, and marital symptoms of the family members of the current and previous generations. The quantitative analysis supported the hypothesis. In a correlation analysis of the first five years of this twenty-year study, multigenerational functioning, especially nuclear family of origin functioning, was associated with nuclear family functioning.     

Applicant Faking,Social Desirability,and the Prediction of Counterproductive Work Behaviors

Recent studies have pointed to within-subjects designs as an especially effective tool for gauging the occurrence of faking behavior in applicant samples. The current study utilized a within-subjects design and data from a sample of job applicants to compare estimates of faking via within-subjects score change to estimates based on a social desirability scale. In addition, we examined the impact of faking on the relationship between Conscientiousness and counterproductive work behaviors (CWBs), as well as the direct linkage between faking and CWBs. Our results suggest that social desirability scales are poor indicators of within-subjects score change, and applicant faking is both related to CWBs and has a negative impact on the criterion-related validity of Conscientiousness as a predictor of CWBs.     

Psychomotor abilities via touch‐panel testing: Measurement innovations,construct, and criterion validity

Assessment of psychomotor abilities for prediction of human performance is briefly reviewed. Reasons for the abandonment of psychomotor testing for selection applications are described. We review innovations in touch‐sensitive computer monitors as a methodology for relatively low‐cost, highly flexible test development, validation, and application of standard psychomotor tests. The development and evaluation of 5 psychomotor test types are described including discrete response tests (choice‐simple reaction time [RT], serial RT, and tapping) and continuous‐response tests (maze tracing and mirror tracing). Two empirical studies of the new psychomotor tests are presented, with a broad array of perceptual speed and cognitive abilities providing evidence for construct validity. In addition, some of the psychomotor tests are validated against a real‐time simulation criterion (the Kanfer‐Ackerman Air Traffic Controller Task©). We argue that these new innovations provide a means toward revisiting psychomotor testing to augment employee selection batteries.     

Do Patients With Psychosis Experience Loss and Grief As a Result of Their Illness?

BACKGROUND: Depression and suicidality are frequently reported in patients with psychosis and schizophrenia, but the grief process that may be associated with this illness has not been systematically studied. In this study, we examined whether patients diagnosed with psychosis identify, grieve, and mourn losses engendered by the illness. METHOD: 24 patients diagnosed with psychosis in the past five years were surveyed to indicate whether their illness led to losses, and to describe their responses to the losses. Psychosis-related perceived losses were surveyed using three subscales of a loss and grief questionnaire (loss of self, self-care, and roles). Their relationship with beliefs about the illness, symptomatology, coping style, and self-efficacy and insight was studied. RESULTS: 23 (96%) patients named specific losses, and 16 patients (67%) reported feelings associated with grief and mourning. More than half reported loss of self-esteem at the onset of illness and only half saw themselves as having improved in the past month. Patients reported more loss within the past month than at the onset of illness. In the past month, patients with an intact sense of self experienced greater self-efficacy (r = .568, p < .004) while those with loss of self reported feelings of shame (r = ?.582, p < .003). Only patients with insight associated the onset of illness with loss. In the past month, most patients saw themselves as experiencing loss. DISCUSSION: The study results suggest that at some distance from diagnosis, patients still experience themselves as having much loss due to their illness. These unresolved feelings may indicate complicated mourning. Insight appears to be associated with the ability to look back at the onset of the illness and recognize that it engendered losses. Further study of the process of and barriers to grief and mourning is recommended. In clinical practice, the assessment of grief as a part of post-psychotic recovery could lead to providing more appropriate treatment and lead to a positive outcome.     

Gaze and informativeness during category learning: Evidence for an inverse relation

In what follows, we explore the general relationship between eye gaze during a category learning task and the information conveyed by each member of the learned category. To understand the nature of this relationship empirically, we used eye tracking during a novel object classification paradigm. Results suggest that the average fixation time per object during learning is inversely proportional to the amount of information that object conveys about its category. This inverse relationship may seem counterintuitive; however, objects that have a high-information value are inherently more representative of their category. Therefore, their generality captures the essence of the category structure relative to less representative objects. As such, it takes relatively less time to process these objects than their less informative companions. We use a general information measure referred to as representational information theory (Vigo, 2011a, 2013a) to articulate and interpret the results from our experiment and compare its predictions to those of three models of prototypicality.
