We consider two versions of truth as grounded in verification procedures: Dummett??s notion of proof as an effective way to establish the truth of a statement and Hintikka??s GTS notion of truth as given by the existence of a winning strategy for the game associated with a statement. Hintikka has argued that the two notions should be effective and that one should thus restrict one??s attention to recursive winning strategies. In the context of arithmetic, we show that the two notions do not coincide: on the one hand, proofs in PA do not yield recursive winning strategies for the associated game; on the other hand, there is no sound and effective proof procedure that captures recursive GTS truths. We then consider a generalized version of Game Theoretical Semantics by introducing games with backward moves. In this setting, a connection is made between proofs and recursive winning strategies. We then apply this distinction between two kinds of verificationist procedures to a recent debate about how we recognize the truth of G?delian sentences. 相似文献

Most longitudinal, correlational studies on health-behaviour change examine effects of Time1 social-cognitive predictors on subsequent behaviour. In contrast, our research focusses on associations between changes in predictors with change in behaviour. The Health Action Process Approach (HAPA) distinguishes between motivational predictors for intention formation and volitional predictors for behavioural change and served as theoretical basis. Two online-studies were launched targeting different behaviours (low-fat diet, smoking), different samples (Study 1: N = 469; Study 2: N = 441) and different time spans (Study 1: 3 months, Study 2: 4 weeks). Data were analysed by means of structural equation modelling with latent difference scores. Both studies resulted in almost parallel prediction patterns. Change in risk awareness and change in outcome expectancies did not result in change in intentions, whereas change in self-efficacy was of crucial importance. Change in behaviour was associated with change in action planning and action control over and above the effects of intentions. In one study, increases in self-efficacy yielded increases in behaviour change. Results demonstrate that change in action planning and especially action control was of great importance for behaviour change across two different behaviours. Analysing change in social-cognitive predictors allows drawing precise conclusions for interventions. 相似文献

Threat-related processing supports prospective memory retrieval for people with obsessive tendencies

Obsessive-compulsive disorder can result in a variety of deficits to cognitive performance, including negative consequences for attention and memory performance. The question addressed in the current study concerned whether this disorder influenced performance in an event-based prospective memory task. The results from a subclinical population indicated that, relative to non-anxious controls and mildly depressed controls, people with obsessive-compulsive tendencies (washing compulsions) incur decrements in remembering to respond to cues related to a neutral intention (respond to animals). This deficit was ameliorated by giving the subclinical group an intention about a threat-related category (respond to bodily fluids) and cueing them with concepts that they had previously rated as particularly disturbing to them. Thus, their normal attentional bias for extended processing of threat-related information overcame their natural deficit in event-based prospective memory. 相似文献

ABSTRACTSix studies explored the preponderance of people who experience third-person perspective observer memories during autobiographical memory retrieval. The concept of first-person field versus observer memories has been extensively used in the areas of cognitive, social, and clinical psychology. An implicit assumption is the idea that most people use both of these perspectives. What varies are the circumstances that bias people to use one perspective over another for a given autobiographical memory. We challenge that assumption across six studies by showing that, while there are some people who report to regularly have observer memories, there are also those that report to rarely or never have them. These reports were found to be related to levels of reported dissociative experiences. We discuss how this difference in the experience of observer memories may also reflect other innate characteristics, and may correspond to predispositions for various pathologies, including depression, social phobia, and post-traumatic stress disorder. 相似文献

Two processes are thought to support visual recognition memory (VRM): Familiarity and recollection. The former is generally considered to be faster. However, the relationship between the precise onset of the two processes is unclear. Here, we use a novel paradigm, the SAB (Speed and Accuracy Boosting procedure) that constrains participants to use their fastest strategy and provides a continuous distribution of their reaction times. We show that fast recognition occurs as early as ~370 ms, a limit that appears incompressible whatever types of stimuli were used. In a second experiment, running the SAB in conjunction with a modified version of the remember/know paradigm, we show that responses up to ~420 ms are based solely on familiarity. These time limits of 370 ms and 420 ms provide strong constraints on the neural mechanisms underlying VRM and suggest that the fastest, familiarity-based, responses could rely on the visual ventral stream only. 相似文献

ABSTRACTPatients who have been attended to at psychiatric institutions sometimes fail to keep their scheduled appointments. This study was designed to assess the extent and determinants of missed first clinic appointments among recently discharged patients with schizophrenia. A total of 311 inpatients with a diagnosis of schizophrenia were participated in the study. The diagnosis of schizophrenia was confirmed using Munich version of the Composite International Diagnostic Interview. Socio-demographic and clinical data were collected using the socio-demographic questionnaire while analysis was done using SPSS (version 16). The rate of missed first outpatient appointment was found to be 25.7%. Missed appointment was associated with male gender, state of origin outside the study site, long distance from hospital to place of abode, longer appointment duration and illness severity at discharge. The findings in this study support the need for the introduction of community psychiatric services to improve patient access to services in Nigeria. 相似文献

This study explored the psychosocial issues faced by children and adolescents with HIV in Botswana. Data on psychosocial issues were collected from 27 young children aged 5–9 years and 128 adolescents aged 10–19 years (n = 155). Data were analysed using Microsoft Excel 2007 and MiniTab16. The most frequently identified psychosocial issues were behaviour problems (70%), family issues (58%), and HIV medication adherence (57%). Compared to young children, adolescents were more likely to have HIV medication adherence issues. Missed appointments were most commonly attributed to patient forgetfulness (21%) and conflicting appointments (18%). 相似文献

Scientific discoveries about the dangers of smoking and antismoking actions carried out in Western countries over recent decades have progressively helped create an antismoking social norm. Nevertheless, many smokers still refuse to quit. We conducted two studies to investigate smokers' resistance to this norm as a function of their personal self‐esteem (PSE) and group‐based self‐esteem (GBSE). An initial correlational study assessed smokers' perception of the antismoking social norm, their PSE, and their antismoking attitudes. Smokers with low PSE had lower antismoking attitudes than those with high PSE when the antismoking norm was strong. The second study assessed GBSE (i.e., smokers' satisfaction as smokers) and manipulated both the strength of the antismoking norm and PSE (i.e., focus on personal weaknesses or strengths). Smokers with low PSE displayed the lowest antismoking attitudes when the antismoking norm was strong and their GBSE was high. These results show that the antismoking norm can produce paradoxical effects and suggest that the way individuals cope with stigmatization is affected by the interplay between PSE and GBSE.
