Korsakoff's syndrome (KS) is characterized by explicit amnesia, but relatively spared implicit memory. The aim of this study was to assess to what extent KS patients can acquire spatial information while performing a spatial navigation task. Furthermore, we examined whether residual spatial acquisition in KS was based on automatic or effortful coding processes. Therefore, 20 KS patients and 20 matched healthy controls performed six tasks on spatial navigation after they navigated through a residential area. Ten participants per group were instructed to pay close attention (intentional condition), while 10 received mock instructions (incidental condition). KS patients showed hampered performance on a majority of tasks, yet their performance was superior to chance level on a route time and distance estimation tasks, a map drawing task and a route walking task. Performance was relatively spared on the route distance estimation task, but there were large variations between participants. Acquisition in KS was automatic rather than effortful, since no significant differences were obtained between the intentional and incidental condition on any task, whereas for the healthy controls, the intention to learn was beneficial for the map drawing task and the route walking task. The results of this study suggest that KS patients are still able to acquire spatial information during navigation on multiple domains despite the presence of the explicit amnesia. Residual acquisition is most likely based on automatic coding processes. 相似文献

The drawbacks of traditional research into emotional processes have led us to develop a set of methodologies for investigating them in everyday face-to-face communication. The conceptual basis of these procedures is a model of the eliciting conditions of emotional processes as well as a conceptualization of the emotional processes themselves. On the basis of the assumption of conversation as a rule-governed process, one can describe its default temporal, formal, and functional features, for which we use the MAS EDIT and SEQ programs, and the minimal model of communicative exchange, respectively. Violations of these default rules can be identified as unexpected/temporally unpredictable events eliciting emotionalization. The nature of emotionalization is determined by the psychological principle of “standard and deviation.” Its investigation under natural conditions requires the following: A noninvasive method of data acquisition (including procedures for rejecting faulty or missing values), measurement (high-resolution recording of physiological, psychomotor, and vocal variables), and the (nonstatistical) construction of an inventory or “relevant effects” (contrastive and template analysis). Finally, we depict three routes of investigating time courses of activation changes as dependent and independent variables and as a target of modification and reflection. 相似文献

Traditional methods of analyzing human peripheral blood flow (PBF) do not account for its continuous nature or small-scale
variation. Sequel transformation is presented as a new methodology for measuring these variations. This analysis generates
a richer record of aspects of activation of the autonomous nervous system than traditional interbeat-interval (IBI) measurement.
Presumably, in addition to heartbeat (i.e., IBI), other information can be extracted that is consistent with the influence
of several physiological and psychological factors. This kind of variation is reflected in the PBF signal. After determining
and extracting relevant events from vascular volume data generated by sequel transformation, we demonstrate the use of template
analysis to analyze patterns of events as time courses of activation. All procedures are included in the computer program
VASC Analyzer. 相似文献

Two experiments compared 6‐month‐old infants as they reach for an object. All were proficient reachers but with different levels of sitting ability. The object was presented at various distances, within and beyond reach of the infant. In the first experiment, the scaling of perceived reachability in infants with different postural abilities (i.e. non‐sitter, near‐sitter, and sitter infants) was explored. The second experiment investigated the role of proprioception in the scaling of perceived reachability by non‐sitter and sitter infants. In general, results suggest that perceived reachability is calibrated in relation to the degree of postural control achieved by the infant. Infants demonstrate a sense of their own situation in the environment as well as a sense of their own body effectivities. Both determine the execution, or non‐execution, of reaching for a distal object by young infants. Copyright © 1999 John Wiley & Sons, Ltd. 相似文献

According to the seductive detail effect, adding interesting but irrelevant information (i.e., seductive details) can be detrimental to learning success. In this study, it was explored within two experiments whether the valence of text‐based seductive details might affect learning outcomes differently. For Experiments 1 and 2, we pretested text‐based seductive details for their emotional valence (n = 32 or n = 25 students, respectively). For the main studies of Experiments 1 (n = 105) and 2 (n = 131), university students were randomly assigned to one of four conditions that varied with respect to the presence of seductive details and their emotional valence (no vs. positive vs. negative vs. neutral). Unexpectedly, results revealed in both experiments no seductive details effect and also no differences between the three seductive detail conditions for the used learning outcome measures retention and transfer. Possible reasons for these findings and their implications are discussed. 相似文献

The present study investigated the psychological health effects and motivational origins of digital stress based on a representative survey of 1,557 German Internet users between 14 and 85 years of age. Communication load resulting from private e-mails and social media messages as well as Internet multitasking were positively related to perceived stress and had significant indirect effects on burnout, depression, and anxiety. Perceived social pressure and the fear of missing out on information and social interaction were key drivers of communication load and Internet multitasking. Age significantly moderated the health effects of digital stress as well as the motivational drivers of communication load and Internet multitasking. The results, thus, underline the need to address digital stress from a life span perspective. 相似文献

Cognitive-behavioral therapy (CBT) and selective serotonin reuptake inhibitors (SSRIs) are the two first-line treatments for depression, but little is known about their effects on quality of life (QOL). A meta-analysis was conducted to examine changes in QOL in adults with major depressive disorder who received CBT (24 studies examining 1969 patients) or SSRI treatment (13 studies examining 4286 patients) for their depression. Moderate improvements in QOL from pre to post-treatment were observed in both CBT (Hedges’ g = .63) and SSRI (Hedges’ g = .79) treatments. The effect size remained stable over the course of the follow-up period for CBT. No data were available to examine follow-ups in the SSRI group. QOL effect sizes decreased linearly with publication year, and greater improvements in depression were significantly associated with greater improvements in QOL for CBT, but not for SSRIs. CBT and SSRIs for depression were both associated with moderate improvements in QOL, but are possibly caused by different mechanisms. 相似文献

Approximately 2.5 million children in the European Union and the United States have incarcerated parents, the vast majority of which are fathers. Three experiments modeled on real legal cases (total N = 881) investigated how parent gender affects decisions regarding contact between incarcerated parents and their children. Results showed that measures facilitating relationship maintenance in relevant domains (sentence length, visitation rights, and alleviating postsentencing conditions) were supported less when they involved a father despite identical prior information about the legal case. Mediation analyses suggest two distinct processes explaining these disparities: participants' crime‐related attributions, and their stereotypical expectations about the different familial roles of mothers and fathers. Practical implications of these findings and directions for future research are discussed. 相似文献
