In multiple-list learning, retrieval during learning has been suggested to improve recall of the single lists by enhancing list discrimination and, at test, reducing interference. Using electrophysiological, oscillatory measures of brain activity, we examined to what extent retrieval during learning facilitates list encoding. Subjects studied 5 lists of items in anticipation of a final cumulative recall test and did either a retrieval or a no-retrieval task between study of the lists. Retrieval was from episodic memory (recall of the previous list), semantic memory (generation of exemplars from an unrelated category), or short-term memory (2-back task). Behaviorally, all 3 forms of retrieval enhanced recall of both previously and subsequently studied lists. Physiologically, the results showed an increase of alpha power (8-14 Hz) from List 1 to List 5 encoding when no retrieval activities were interpolated but no such increase when any of the 3 retrieval activities occurred. Brain-behavior correlations showed that alpha-power dynamics from List 1 to List 5 encoding predicted subsequent recall performance. The results suggest that, without intermittent retrieval, encoding becomes ineffective across lists. In contrast, with intermittent retrieval, there is a reset of the encoding process for each single list that makes encoding of later lists as effective as encoding of early lists. 相似文献

Cognitive insight is the ability to monitor and correct one's own erroneous convictions. The Beck Cognitive Insight Scale (BCIS) assesses two sub‐dimensions of cognitive insight: self‐reflectiveness (SR), which is the attitude of questioning one's own judgments; and self‐certainty (SC), which is the unwillingness to modify and correct one's own convictions. There is little information about cognitive insight in healthy participants (HP). Here we investigated the socio‐demographic and neuropsychological correlates of cognitive insight in 50 HP who were administered the BCIS and a comprehensive neuropsychological battery. The global BCIS R‐C index correlated positively with age and WCST perseverative errors. SR correlated positively with age. These data support the hypothesis that a less self‐reflective and more self‐confident style is cognitively functional in HP. Thus, what has been found malfunctioning in mental illnesses is adaptive in HP. Future studies should consider a wider range of factors that might affect this complex construct.

An investigation of the psychometric properties of the German version of the Group Questionnaire (GQ; Krogel 2009) is described. The GQ is a self-report instrument economically enabling the assessment of helpful aspects of relationships within small groups. Due to the limited length of the questionnaire it provides a tool of monitoring bonding to the group, the quality of the working relationship as well as negative aspects during group treatment. One advantage of the GQ is that it measures relationships on three different relational levels (group members, group leader and the group as a whole). Following a test of the multidimensional structure of the GQ-D using data from a multisite study (N=438) with structural equation models, the GQ-D was validated using other process measures. The GQ-D proved to be an objective, valid and reliable measure to assess relevant therapeutic relationships within groups. 相似文献

Robots are increasingly expected to perform tasks in complex environments. To this end, engineers provide them with processing
architectures that are based on models of human information processing. In contrast to traditional models, where information
processing is typically set up in stages (i.e., from perception to cognition to action), it is increasingly acknowledged by
psychologists and robot engineers that perception and action are parts of an interactive and integrated process. In this paper,
we present HiTEC, a novel computational (cognitive) model that allows for direct interaction between perception and action
as well as for cognitive control, demonstrated by task-related attentional influences. Simulation results show that key behavioral
studies can be readily replicated. Three processing aspects of HiTEC are stressed for their importance for cognitive robotics:
(1) ideomotor learning of action control, (2) the influence of task context and attention on perception, action planning,
and learning, and (3) the interaction between perception and action planning. Implications for the design of cognitive robotics
are discussed. 相似文献

A Dialectical Behavior Therapy Skills training manual (DBT Skills) was adapted for use with caregivers of individuals with dementia. Implementation occurred in a community clinic with a heterogeneous caregiver group at risk for elder abuse. Sixteen caregivers completed the 9-week group. The results point to improved psychosocial adjustment, particularly increased problem-focused coping, enhanced emotional well-being, and less fatigue. Caregivers tended to utilize individual therapeutic services at a higher rate during the period of group attendance, indicative of appropriate help-seeking behavior in highly demanding situations. Six of the 16 caregivers repeated the training sequence in “booster” groups. Follow-up data from the booster groups suggest that high-risk caregivers may require continuing support to maintain treatment gains. In addition to demonstrating the feasibility of DBT Skills with caregivers, the results warrant a controlled outcome evaluation. 相似文献

Adequate short-term responses to stressors are of great importance for the health and well-being of individuals and factors modulating the physiological stress response (e.g., controllability, suddenness, familiarity) of a stimulus are well described under laboratory conditions. In the present study we aimed at investigating the stress response in greylag geese (Anser anser) in the field, confronting individuals with naturally occurring stressors. We measured beat-to-beat heart rate (HR) via fully implanted transmitters during three different experimental challenges: (1) catching and holding, (2) confrontation with a model predator, and (3) approach by different humans. We compared this to a control period and HR during agonistic encounters, a naturally occurring stressor. All three experimental situations evoked a HR increase. Highest HR responses were elicited by catching and holding the animals. In the third experiment, HR responses were greatest when the geese were approached by a human stranger (i.e., somebody the geese have never seen before). Hence, geese discriminated between different kinds of stressors and adjusted their physiological response depending on the type of stressor. Our results show that geese were able to discriminate between individual humans. In line with a number of lab studies, we suggest that particularly the controllability of certain situation determines the intensity of the HR response, also in a natural setting in the field. 相似文献

The assessment of trauma related-disorders belongs to the most controversial and medically as well as juridically most broadly discussed fields. Accordingly, the juridical basis and clinical implications are presented and discussed. In doing so, among other things the principles of the causality judgement, the damage-related factors and those damage-independent factors which have to be considered are described. They are discussed in the context of social-juridical and insurance-juridical contexts. Some specific features of the clinical investigation situation are shown. 相似文献

One of the functions of supervision in psychotherapy training is quality assurance. In order to fulfill this function the quality of supervision itself needs to be high and needs to be controlled. Thus in a large survey of psychotherapy training in Germany questions related to the quality of supervision were included in the survey. Answers to those questions from different samples (trainees, alumni, trainers, training institutes, expert organizations) were compiled. Quantitative and qualitative methods were used. Satisfaction and usefulness ratings with individual and group supervision were high to very high. Supervision amount, group size and frequency were rated as adequate. Criticism pertained to the lack of systematic evaluation, insufficient qualification of the supervisors and lacking integration of supervision into the whole training. As supervision is a very important part of psychotherapy training measures for quality assurance and improvement are necessary. 相似文献

Cognitive conflict plays an important role in tuning cognitive control to the situation at hand. On the basis of earlier findings demonstrating emotional modulations of conflict processing, we predicted that affective states may adaptively regulate goal-directed behavior that is driven by conflict. We tested this hypothesis by measuring conflict-driven control adaptations following experimental induction of four different mood states that could be differentiated along the dimensions of arousal and pleasure. After mood states were induced, 91 subjects performed a flanker task, which provided a measure of conflict adaptation. As predicted, pleasure level affected conflict adaptation: Less pleasure was associated with more conflict-driven control. Arousal level did not influence conflict adaptation. This study suggests that affect adaptively regulates cognitive control. Implications for future research and psychopathology are discussed. 相似文献
