Results obtained with preschool children (Homo sapiens) were compared with results previously obtained from capuchin monkeys (Cebus apella) in matching-to-sample tasks featuring hierarchical visual stimuli. In Experiment 1, monkeys, in contrast with children, showed an advantage in matching the stimuli on the basis of their local features. These results were replicated in a 2nd experiment in which control trials enabled the authors to rule out that children used spurious cues to solve the matching task. In a 3rd experiment featuring conditions in which the density of the stimuli was manipulated, monkeys' accuracy in the processing of the global shape of the stimuli was negatively affected by the separation of the local elements, whereas children's performance was robust across testing conditions. Children's response latencies revealed a global precedence in the 2nd and 3rd experiments. These results show differences in the processing of hierarchical stimuli by humans and monkeys that emerge early during childhood. 相似文献

In the Implicit Association Test (IAT; Greenwald, McGhee, & Schwartz, 1998) involving race classification (white vs. black),
an apparent compatibility effect is found between the “pleasant” attribute and the “white” category. This race IAT effect
has been interpreted in terms of “implicit prejudice”—that is, more positive evaluation of whites than of blacks that is not
open to consciousness. We suggested instead that the race IAT effect is better interpreted in terms of the salience asymmetry
account proposed by Rothermund and Wentura (2004), whereby greater familiarity with the white category makes it more salient.
Evidence that has been presented against the familiarity interpretation is considered, and alternative interpretations of
findings related to the race IAT effect are discussed. 相似文献

This article examines whether various cognitive abilities are associated with symptoms of ADHD. Cognitive ability is conceptualized using Cattell-Horn-Carroll (CHC) theory as measured using the Woodcock-Johnson Tests of Cognitive Ability (3rd ed.). This article also examines whether test session behavior mediates the association between cognitive ability and ADHD. Participants are children ages 6 to 12 with (n= 33) and without (n= 19) ADHD. Results show that inattentive symptoms of ADHD are significantly related to the CHC ability of processing speed above and beyond the effect of test session behavior. Symptoms of ADHD (both inattention and hyperactivity/impulsivity) are also significantly associated with visual spatial processing, but this is completely mediated by test session behavior. It is concluded that inattentive symptoms of ADHD are associated with slower processing speed and that this relationship is not explained by test session behavior. 相似文献

Using an adaptation of the Attentional Networks Test, we investigated aspects of executive control in children with chromosome 22q11.2 deletion syndrome (DS22q11.2), a common but not well understood disorder that produces non-verbal cognitive deficits and a marked incidence of psychopathology. The data revealed that children with DS22q11.2 demonstrated greater difficulty than controls in locating and processing target items in the presence of distracters. Importantly, children with DS22q11.2 showed a deficit in the ability to monitor and adapt to stimulus conflict. These data provide evidence of inadequate conflict adaptation in children with DS22q11.2, a problem that is also present in schizophrenia. The findings of specific executive dysfunction in this group may provide a linkage between particular genetic abnormalities and the development of psychopathology. 相似文献

Acceptance of cosmetic surgery: scale development and validation 总被引:4,自引:1,他引:3
We conducted a set of four studies with a total of 1288 adult and undergraduate women and men to develop the Acceptance of Cosmetic Surgery Scale. These studies provide evidence of this scale's reliability, as well as convergent and discriminant validity. Initial explorations using this 15-item scale indicate that acceptance of cosmetic surgery is negatively related to satisfaction with physical appearance and positively related to attitudes about make-up use. The acceptance of cosmetic surgery may be more related to fears about becoming unattractive than to hopes of becoming more attractive. Cosmetic surgery attitudes were positively related to age for women but not for men. The study's limitations and implications are discussed. 相似文献

Abstract-Examining the receptive fields of brain signals can elucidate how information impinging on the former modulates the latter. We applied this time-honored approach in early vision to the higher-level brain processes underlying face categorizations. Electroencephalograms in response to face-information samples were recorded while observers resolved two different categorizations (gender, expressive or not). Using a method with low bias and low variance, we compared, in a common space of information states, the information determining behavior (accuracy and reaction time) with the information that modulates emergent brain signals associated with early face encoding and later category decision. Our results provide a time line for face processing in which selective attention to diagnostic information for categorizing stimuli (the eyes and their second-order relationships in gender categorization; the mouth in expressive-or-not categorization) correlates with late electrophysiological (P300) activity, whereas early face-sensitive occipito-temporal (N170) activity is mainly driven by the contralateral eye, irrespective of the categorization task. 相似文献

Psychoanalytic psychotherapy in clinical practice is traditionally a long-term treatment conducted by well-trained psychotherapists. However, very few studies have been published that evaluate the effects of such treatment. To redress this lack of studies, 55 individuals selected for long-term psychoanalytic psychotherapy (average, 3 years) were invited to participate in a naturalistic study. The psychotherapists had a mean of 15 years of professional experience. The 36 patients who completed psychotherapy manifested a substantial reduction in symptomatic suffering and decreased levels of character pathology, as measured by the Karolinska Psychodynamic Profile (KAPP) and the Karolinska Scales of Personality. Generally, such changes were not found in the individuals who did not engage in treatment. In the therapy group, improvements were found on eight KAPP subscales defining different aspects of character: Intimacy and Reciprocity, Frustration Tolerance, Regression in the Service of the Ego, Coping with Aggressive Affects, Conceptions of Bodily Appearance and their Significance for Self-esteem, Sexual Function, Sexual Satisfaction, and Personality Organization. The results indicate that individuals who engaged in psychotherapy improved their capacity to handle crucial aspects of life and reduced their symptomatic suffering. 相似文献

The present study examined performance during 3 hr. of simulated sentry duty with and without the intermittent administration of low-level sensory stimuli (odor or vibration). For odor and control conditions, target-detection latency increased steadily over the course of the 3-hr. session. Administration of a tactile stimulus reduced the increase in detection latency compared to that found in odor and control conditions. For all conditions, there were no significant differences in target-detection frequency, shot accuracy, or friend-foe discrimination. Across all conditions, restlessness (motor activity) increased significantly the first hour and remained elevated for the rest of the session. Subjective measures of workload (NASA-TLX) indicated that the 3-hr. task rated high on physical demand, mental demand, frustration, and overall workload. These findings suggest that the intermittent delivery of a clearly detectable tactile stimulus can reduce reaction-time decrements that occur as time on task increases. 相似文献

Using Irish suicide data for the period 1990-1998, the independent effects of month and day adjusting for age, gender, and calendar year effects and distinguishing between holiday and working Mondays were assessed. The male suicide rate was significantly higher on working Mondays (+31%) and Saturdays (+14%), and during April, June, and August (+17%), after adjustment for the other variables. In contrast, female suicide rates were higher only in August (+35%) and exhibited no day effect. Teenage men had a greater elevation of risk on Saturdays, Sundays, and both working and holiday Mondays than any other group. The study findings should be taken into account in the planning of specialized health care services and helplines for suicidal people. Furthermore, the findings provide support for Gabennesch's (1988) broken promise theory and the relationship between dysfunctions of the serotonergic system and suicidal behavior. 相似文献

In this study, the authors examined time-varying associations between schizotypal (STPD), borderline (BPD), avoidant (AVPD), or obsessive-compulsive (OCPD) personality disorders and co-occurring Axis I disorders in 544 adult participants from the Collaborative Longitudinal Personality Disorders Study. The authors tested predictions of specific longitudinal associations derived from a model of crosscutting psychobiological dimensions (L. J. Siever & K. L. Davis, 1991) with participants with the relevant Axis I disorders. The authors assessed participants at baseline and at 6-, 12-, and 24-month follow-up evaluations. BPD showed significant longitudinal associations with major depressive disorder and posttraumatic stress disorder. AVPD was significantly associated with anxiety disorders (specifically social phobia and obsessive-compulsive disorder). Two of the four personality disorders under examination (STPD and OCPD) showed little or no association with Axis I disorders. 相似文献
