In two experiments, 18-month-old infants’ categorization of 3D replicas and 2D photographs of the same animals and vehicles were compared to explore infants’ flexibility in categorization across different object representations. Using a sequential touching procedure, infants completed one superordinate and two basic-level categorization tasks with 3D replicas, 2D cut out photographs, or 2D images on photo cubes (“2D cubes”). For superordinate sets, 3D replicas elicited longer mean run lengths than 2D cut outs, and 3D replicas elicited equivalent mean run lengths as 2D cubes. For basic-level sets, infants categorized high-contrast animal sets when presented with 3D replicas, but they failed to categorize any of the 2D photograph sets. Categorization processes appear to differ for 3D and 2D stimuli, and infants’ discovery of object properties over time while manipulating objects may facilitate categorization, as least at the superordinate level. These findings are discussed in the context of infants’ representation abilities and the integration of perception and action.  相似文献

Although externally as well as internally-guided eye movements allow us to flexibly explore the visual environment, their differential neural mechanisms remain elusive. A better understanding of these neural mechanisms will help us to understand the control of action and to elucidate the nature of cognitive deficits in certain psychiatric populations (e.g. schizophrenia) that show increased latencies in volitional but not visually-guided saccades. Both the superior precentral sulcus (sPCS) and the intraparietal sulcus (IPS) are implicated in the control of eye movements. However, it remains unknown what differential contributions the two areas make to the programming of visually-guided and internally-guided saccades. In this study we tested the hypotheses that sPCS and IPS distinctly encode internally-guided saccades and visually-guided saccades. We scanned subjects with fMRI while they generated visually-guided and internally-guided delayed saccades. We used multi-voxel pattern analysis to test whether patterns of cue related, preparatory and saccade related activation could be used to predict the direction of the planned eye movement. Results indicate that patterns in the human sPCS predicted internally-guided saccades but not visually-guided saccades in all trial periods and patterns in the IPS predicted internally-guided saccades and visually-guided saccades equally well. The results support the hypothesis that the human sPCS and IPS make distinct contributions to the control of volitional eye movements.  相似文献

The continuum of broaching behavior is a conceptual framework explicating how counselors broach or have explicit discussions about racial, ethnic, and cultural factors with their clients during treatment ( Day‐Vines et al., 2007 ). Counselors can assume 5 particular broaching orientations: avoidant, isolating, continuing/incongruent, integrated/congruent, and infusing. The authors operationalized the continuum of broaching behavior using the Broaching Attitudes and Behavior Scale and found support for a 4‐factor model of broaching behavior. El espectro de comportamiento de abordamiento es un marco conceptual que explica cómo los consejeros abordan o tienen discusiones específicas sobre factores raciales, étnicos y culturales con sus clientes durante el tratamiento ( Day‐Vines et al., 2007 ). Los consejeros pueden asumir 5 orientaciones de abordamiento particulares: evasiva, aislante, continua/incongruente, integrada/congruente e infundida. Los autores operativizaron el espectro de comportamiento de abordamiento usando la Escala de Actitudes de Abordamiento y Comportamiento y hallaron respaldo para un modelo del comportamiento de abordamiento de 4 factores.  相似文献

Abstract

This research examined the relationship between salespersons' perceptions of role conflict and role ambiquity from various sources and the degree of agreement between salespeople and sales managers on salesperson performance. Three sources of role ambiguity were found to explain the most variance in performance congruence. Implications for management are discussed.  相似文献

Rationale: To provide a better understanding of cognitive functioning, motor outcome, behavior and quality of life after childhood stroke and to study the relationship between variables expected to influence rehabilitation and outcome (age at stroke, time elapsed since stroke, lateralization, location and size of lesion).

Methods: Children who suffered from stroke between birth and their eighteenth year of life underwent an assessment consisting of cognitive tests (WISC-III, WAIS-R, K-ABC, TAP, Rey-Figure, German Version of the CVLT) and questionnaires (Conner's Scales, KIDSCREEN).

Results: Twenty-one patients after stroke in childhood (15 males, mean 11;11 years, SD 4;3, range 6;10–21;2) participated in the study. Mean Intelligence Quotients (IQ) were situated within the normal range (mean Full Scale IQ 96.5, range IQ 79–129). However, significantly more patients showed deficits in various cognitive domains than expected from a healthy population (Performance IQ p?=?.000; Digit Span p?=?.000, Arithmetic's p?=?.007, Divided Attention p?=?.028, Alertness p?=?.002). Verbal IQ was significantly better than Performance IQ in 13 of 17 patients, independent of the hemispheric side of lesion. Symptoms of ADHD occurred more often in the patients' sample than in a healthy population (learning difficulties/inattention p?=?.000; impulsivity/hyperactivity p?=?.006; psychosomatics p?=?.006). Certain aspects of quality of life were reduced (autonomy p?=?.003; parents' relation p?=?.003; social acceptance p?=?.037). Three patients had a right-sided hemiparesis, mean values of motor functions of the other patients were slightly impaired (sequential finger movements p?=?.000, hand alternation p?=?.001, foot tapping p?=?.043). In patients without hemiparesis, there was no relation between the lateralization of lesion and motor outcome. Lesion that occurred in the midst of childhood (5–10 years) led to better cognitive outcome than lesion in the very early (0–5 years) or late childhood (10–18 years). Other variables such as presence of seizure, elapsed time since stroke and size of lesion had a small to no impact on prognosis.

Conclusion: Moderate cognitive and motor deficits, behavioral problems, and impairment in some aspects of quality of life frequently remain after stroke in childhood. Visuospatial functions are more often reduced than verbal functions, independent of the hemispheric side of lesion. This indicates a functional superiority of verbal skills compared to visuospatial skills in the process of recovery after brain injury. Compared to the cognitive outcome following stroke in adults, cognitive sequelae after childhood stroke do indicate neither the lateralization nor the location of the lesion focus. Age at stroke seems to be the only determining factor influencing cognitive outcome.  相似文献

Background

The therapeutic relationship is a central factor for psychotherapy, which may be at least partially explained by attachment theory. However, research concerning the conditions under which attachment-related needs are activated in treatment followed by possibly dysfunctional coping strategies is rare.

Patients and methods

Semi-structured interviews on attachment-related situations in psychotherapies were conducted with 36 inpatients and then rated with regard to content.

Results

Triggers for attachment-related needs in therapies were interpersonal conflict and loss, beginning and end of therapy, symptom burden, specific interventions, addressing the therapeutic relationship and change of setting from outpatient to inpatient treatment. This was related to themes of desire for help and support, experience of rejection, self-disclosure and desire for understanding.

Conclusions

The attachment system is activated in therapies similar to other interpersonal situations. The results may help to become more sensitive to attachment-related situations and needs.  相似文献

The present longitudinal study examined the role of career values for work engagement across the transition from university education to working life. Finnish young adults reported on their career values (intrinsic, rewards, and security values) at the age of 23; and the degree of person–organization fit (value congruence, and congruence between one's education and the job), subjective income and economic stress two years later at the age of 25. Work engagement was assessed at both measurement points. Structural equation modeling results showed, first, that intrinsic but not rewards or security career values were related to work engagement. Second, value congruence and having a job which was related to young adults' educational field were positively associated with work engagement. Our findings suggest that along with person–organization fit, intrinsic career values are a significant factor in shaping and facilitating successful transitions from education to work.  相似文献

Concern about the welfare of professional dance students is growing as it becomes clearer that the training is not producing emotionally healthy and mature young people. Psychodynamic ideas and concepts offer a means of analysing the problems of the training and indicating where change needs to be implemented. This paper looks first at the areas of adolescent development towards separation, autonomy, the creation of peer relationships and the development of sexual identity and awareness, and shows how traditional dance training fails to facilitate their growth. The paper then discusses envy and competition and argues that they need to be addressed within dance training if they are not to be so destructive. The paper then suggests that group theory could enable the better use of the dance class. Finally, the idea of the body storyline is used to show that dance training has the capacity to have a creative and remedial effect on students, if training institutions provide a sufficiently facilitating environment.  相似文献

Many research studies address child trauma experiences that take place before foster care placement. However, few studies focus on the types and patterns of trauma experiences that reportedly take place during and after foster care placement; that is, after entry into adult living. This study examined the testimony of 43 foster care youth who spoke to a listening panel comprised of state legislators, child welfare professionals, and university educators. Qualitative analyses of transcribed text data revealed 3 main themes. First, the youth reported experiencing trauma before, during, and after placement. Second, the youth described trauma events and situations that were chronic (i.e., intense, composite, or cumulative). Third, youth offered suggestions for reducing traumatic experiences for foster care youth. They recommended earlier family interventions, access to people who listen and care, improved parenting skills for foster parents, continuity of relationships, and opportunities for leadership for foster youth. Foster youth voices offer important suggestions for building, strengthening, and evaluating trauma-informed systems of care.  相似文献

It is commonly thought that neo-Hobbesian contractarianism cannot yield direct moral standing for marginal humans and animals. However, it has been argued that marginal humans and animals can have a form of direct moral standing under neo-Hobbesian contractarianism: secondary moral standing. I will argue that, even if such standing is direct, this account is unsatisfactory because it is counterintuitive and fragile.  相似文献
