Ernst Kris, a gifted art historian as well as an eminent psychoanalyst, had little regard for the aesthetic value of the spontaneous artistic products of the mentally ill, considering them to be of interest only for the insight they might provide about the patient's psychopathology and unconscious conflicts. Recent scholarship and developments in the art world warrant a critical review of his position, which appears to have derived from his adherence to classical and Renaissance criteria. The works of two untrained and psychiatrically disturbed artists are offered as evidence of their potential aesthetic worth. 相似文献

The purpose of the current study was to investigate a new dissonance-based prevention program that is based on the dual pathway model of eating disorders within the context of an individual's romantic relationship. A total of 209 dating couples participated in a couple-based prevention program or an assessment-only condition and completed measures of body dissatisfaction, thin-ideal internalization, disordered eating, negative affect, and relationship satisfaction at two time points (approximately one week apart) and approximately half of the sample completed 1-month follow-up measures. The prevention program significantly reduced several key risk factors for eating disorders such as environmental pressures to be thin, internalization of the thin and athletic ideals, state body dissatisfaction, and actual-ideal body discrepancy. Initial support was found for the inclusion of couples in eating disorder prevention programs as a successful way of addressing the thin ideal and its detrimental effects for women. 相似文献

In the present study, we investigated response decisions made under conditions of incomplete information in rats. In Experiment
1, rats were trained on either a positive patterning (PP; A-, B-, AB+) or a negative patterning (NP; A+, B+, AB-) instrumental
lever-press discrimination. Subjects that had learned an NP discrimination responded less to Cue A when Cue B was covered
at test. The cover did not, however, affect test responses to Cue A in the PP condition. In Experiment 2, rats received concurrent
training on both PP and NP discriminations. After concurrent training, responses to Cue A were different with B covered versus
uncovered for both NP and PP discriminations. We discuss possible accounts for why exposure to a nonlinearly soluble discrimination
(NP) may have affected sensitivity to cue ambiguity produced by the cover. These results have interesting implications for
representational processes engaged in problem solving. 相似文献

The goal of the present study was to elucidate the role of the human striatum in learning via reward and punishment during an associative learning task. Previous studies have identified the striatum as a critical component in the neural circuitry of reward-related learning. It remains unclear, however, under what task conditions, and to what extent, the striatum is modulated by punishment during an instrumental learning task. Using high-resolution functional magnetic resonance imaging (fMRI) during a reward- and punishment-based probabilistic associative learning task, we observed activity in the ventral putamen for stimuli learned via reward regardless of whether participants were correct or incorrect (i.e., outcome). In contrast, activity in the dorsal caudate was modulated by trials that received feedback--either correct reward or incorrect punishment trials. We also identified an anterior/posterior dissociation reflecting reward and punishment prediction error estimates. Additionally, differences in patterns of activity that correlated with the amount of training were identified along the anterior/posterior axis of the striatum. We suggest that unique subregions of the striatum--separated along both a dorsal/ventral and anterior/posterior axis--differentially participate in the learning of associations through reward and punishment. 相似文献

This study examined the influence of gender, socioeconomic status, and race/ethnicity on the career aspirations of over 22,000 8th and 10th grade youth. The top five occupations identified by youth as aspirations included artist, lawyer, musician, FBI agent, and actor/actress. Top occupations were also reported for each gender × socioeconomic status × race/ethnicity group. Aspirations were coded by social prestige level, minimum education requirements, and median salary. Results revealed significant main effects for socioeconomic status and race/ethnicity as well as significant interaction effects. Further, significant gender main effects and a significant gender × ethnicity interaction were found for occupational prestige and educational requirements. 相似文献

Magnetic resonance imaging studies have begun to map effects of genetic variation on trajectories of brain development. Longitudinal studies of children and adolescents demonstrate a general pattern of childhood peaks of gray matter followed by adolescent declines, functional and structural increases in connectivity and integrative processing, and a changing balance between limbic/subcortical and frontal lobe functions, which extends well into young adulthood. Twin studies have demonstrated that genetic factors are responsible for a significant amount of variation in pediatric brain morphometry. Longitudinal studies have shown specific genetic polymorphisms affect rates of cortical changes associated with maturation. Although over-interpretation and premature application of neuroimaging findings for diagnostic purposes remains a risk, converging data from multiple imaging modalities is beginning to elucidate the influences of genetic factors on brain development and implications of maturational changes for cognition, emotion, and behavior. 相似文献

Studies of human memory often generate data on the sequence and timing of recalled items, but scoring such data using conventional
methods is difficult or impossible. We describe a Python-based semiautomated system that greatly simplifies this task. This
software, called PyParse, can easily be used in conjunction with many common experiment authoring systems. Scored data is
output in a simple ASCII format and can be accessed with the programming language of choice, allowing for the identification
of features such as correct responses, prior-list intrusions, extra-list intrusions, and repetitions. 相似文献

Kafka's writings are frequently interpreted as representing the historical period of modernism in which he was writing. Little
attention has been paid, however, to the possibility that his writings may reflect neural mechanisms in the processing of
self during hypnagogic (i.e., between waking and sleep) states. Kafka suffered from dream-like, hypnagogic hallucinations
during a sleep-deprived state while writing. This paper discusses reasons (phenomenological and neurobiological) why the self
projects an imaginary double (autoscopy) in its spontaneous hallucinations and how Kafka's writings help to elucidate the
underlying cognitive and neural mechanisms. I further discuss how the proposed mechanisms may be relevant to understanding
paranoid delusions in schizophrenia. Literature documents and records cognitive and neural processes of self with an intimacy
that may be otherwise unavailable to neuroscience. To elucidate this approach, I contrast it with the apparently popularizing
view that the symptoms of schizophrenia result from what has been called an operative (i.e., pre-reflective) hyper-reflexivity.
The latter approach claims that pre-reflective self-awareness (diminished in schizophrenia) pervades all conscious experience
(however, in a manner that remains unverifiable for both phenomenological and experimental methods). This contribution argues
the opposite: the "self" informs our hypnagogic imagery precisely to the extent that we are not self-aware. 相似文献

The aim of the current study was to assess the relative uniqueness of three components of male body image (i.e., muscle, body fat, and height dissatisfaction) in the prediction of indices of psychological distress (i.e., depression, eating restraint, eating concerns, and social sensitivity) among a community sample of 228 gay men. Results indicated that body fat dissatisfaction was predictive of all four criterion variables (controlling for muscle dissatisfaction). Conversely, muscle dissatisfaction was only associated with social sensitivity, while height dissatisfaction failed to significantly predict any of the criterion variables. These findings highlight the relative importance of body fat dissatisfaction among gay men and suggest that researchers and clinicians working with this population should utilize measures which include assessment of both muscularity and body fat. 相似文献
