The construct and criterion validity of the Depression Implicit Association Test (Depression IAT) as a marker of an automatic negative self-schema was investigated. The Depression IAT and other measures were administered to a sample of 116 participants (72 females) aged 37.28 (SD = 15.69) that was composed by 56 patients with an history of suicide ideation (SI) and by 60 university students. Combining students and patients’ sub-samples, results revealed that the Depression IAT was significantly and positively correlated with self-report scales of depression and hopelessness as well as with implicit and explicit measures of death-life identification. On the contrary, it was negatively correlated with life satisfaction, optimism, and self-esteem scales. These results give new evidence for the construct validity of the Depression IAT. Moreover, considering only the patients’ sub-sample, significant correlations between Depression IAT scores and SI in the last year, month, and week, as well as in a follow-up observation two months later, were found. These correlations remain unchanged even when the Death IAT was controlled for, supporting the incremental validity of the Depression IAT. Overall, these results provide new evidence for the construct and criterion validity of the Depression IAT as a marker of an automatic negative self-schema. 相似文献

It has been proposed that mood correlates with the breadth of associative thinking. Here we set this hypothesis to the test in healthy and depressed individuals. Generating contextual associations engages a network of cortical regions including the parahippocampal cortex (PHC), retrosplenial complex, and medial prefrontal cortex. The link between mood, associative processing, and its underlying cortical infrastructure provides a promising avenue for elucidating the mechanisms underlying the cognitive impairments in major depressive disorder (MDD). The participants included 15 nonmedicated individuals with acute major depressive episodes and 15 healthy matched controls. In an fMRI experiment, participants viewed images of objects that were either strongly or weakly associated with a specific context (e.g., a beach chair vs. a water bottle) while rating the commonality of each object. Analyses were performed to examine the brain activation and structural differences between the groups. Consistent with our hypothesis, controls showed greater activation of the contextual associations network than did depressed participants. In addition, PHC structural volume was correlated with ruminative tendencies, and the volumes of the hippocampal subfields were significantly smaller in depressed participants. Surprisingly, depressed participants showed increased activity in the entorhinal cortex (ERC), as compared with controls. We integrated these findings within a mechanistic account linking mood and associative thinking and suggest directions for the future. 相似文献

Objective
The IZOF-based probabilistic approach provides a methodology to study within-individual patterns of a performer's states. So far, the time course of physiological data before performance have not been investigated within the probabilistic methodology framework. The purpose of this study was to examine the value of the probabilistic approach in the assessment of the time course of physiological indicators of arousal/activation and vigilance during the period preceding the shot, in comparison with the performance-based method.Design
Longitudinal assessment of psycho-physiological data and performance outcomes was conducted on eight elite pistol shooters in a controlled setting.Methods
Each participant performed 60 air-pistol shots in 2 sessions. Skin conductance level and cardiac activity were recorded. Affective states intensity was evaluated on a modified 11-point Borg scale. Affect, HR and SC level were evaluated with a Performance-based approach and a Probabilistic method, and results compared at an individual level.Results
Findings showed the higher effectiveness of the probabilistic method to analyse physiological parameters (skin conductance and heart rate) and to describe the physiological mechanisms associated with shooters’ performance.Conclusions
The probabilistic method better discerned the contribution of arousal/activation and vigilance to optimal and non-optimal performance in elite shooters, thereby providing a sharper representation of the temporal pattern of performers' states before shooting. From an applied perspective, we believe that the probabilistic approach can help athletes become aware of the subtle variations occurring in their psychophysical states during the preparatory period preceding the shot and not only at the moment of shot release. 相似文献45.

Emotions are a complex phenomenon that entails a tricky problem regarding the measurement. To partially overcome this question, we assess emotions both using self‐report and measures commonly used in neuromarketing. This study assesses the accuracy of the recall after 4 months regarding two social advertising videos about female genital mutilation. Forty female participants were recruited. The skin conductance trend of the participants is different when viewing the two videos. The majority of participants (94.9%) reported that the two videos elicited different emotions (sadness for the first video and anger for the second one). Furthermore, according to arousal and valence model, these data are consistent with the literature that underlines the importance of psychophysiological indexes in measuring emotions and their associations with memory performances. 相似文献

Robotics is emerging as a promising tool for aiding research on animal behavior. The possibility of generating customizable, controllable, and standardized robotic stimuli has been demonstrated through a number of behavioral assays, involving vertebrates and invertebrates. However, the specific appraisal of the nature of robotic stimuli is currently lacking. Here, we attempt to evaluate this aspect in zebrafish, through a within‐subject design in which experimental subjects are faced with three experimental conditions. In the first test, we investigated sociability by measuring zebrafish response to a conspecific separated by a one‐way glass. In the second test, we studied zebrafish behavior in response to a 3D‐printed zebrafish replica actuated along realistic trajectories through a novel four‐degree‐of‐freedom robotic platform. Last, we investigated fear responses in a shelter‐seeking test. In agreement with our expectations, zebrafish exhibited an equivalent preference for live and robotic stimuli, and the degree of preference for the robotic replica correlated negatively with the individual propensity to seek shelter. The equivalent preference for the replica and conspecific suggests that the appraisal of the target stimuli is analogous. The preliminary evidence of a correlation between behavioral responses across tests points to the readability of robotics‐based approaches to investigate interindividual differences. 相似文献

Despite a significant literature on the impact of stress on performance in achievement settings, little is known about whether and how stress might matter for would-be negotiators. In two studies, we investigate how bargainers cognitively appraise a looming negotiation, whether its prospect is stressful and what the consequences are for performance. Individuals who appraised a prospective negotiation as a threat experienced more stress ahead of a negotiation, and reached lower quality deals compared to those who had appraised a challenge. Results from a follow-up experiment showed that would-be negotiators who had appraised a threat behaved more passively and were less likely to use tough tactics compared to those who appraised a challenge. Those who appraised a threat also had relatively inaccurate perceptions of their partners’ priorities and interests, which undermined their outcomes. The outcome advantage for those who appraised a challenge was limited to negotiations that contained integrative potential. 相似文献

One of the most relevant problems in principal component analysis and factor analysis is the interpretation of the components/factors. In this paper, disjoint principal component analysis model is extended in a maximum-likelihood framework to allow for inference on the model parameters. A coordinate ascent algorithm is proposed to estimate the model parameters. The performance of the methodology is evaluated on simulated and real data sets. 相似文献

ObjectivesThis study examined the repertoire of preparation strategies and coping responses that elite modern pentathletes display across pre-, during, and post-competition periods.MethodsSix women and eight men were interviewed using an in-depth, open-ended, and semi-structured approach. The qualitative data were then hierarchically content analysed.ResultsThe findings revealed that perseverance, consistency, and commitment during training were critical components of the athletes' preparation in the days preceding an event. The athletes also presented a range of mental and technical preparation strategies across the competitive phases. These included, among others, competition simulation, mental practice, goal setting, emotion control, behavioural routines, specific technical strategies, attentional strategies, reaction to mistakes, and post-competition self-assessment. In addition, athletes' negative expectations during competition emerged as potential threats to personal achievements and were associated with dysfunctional bodily symptoms related to emotions, attentional difficulties, and coping problems.ConclusionsThe practical implications of these findings are discussed focusing on individual differences in cognitive and emotional experiences, and pre-, during, and post-competition strategies. 相似文献

Cognitive pragmatics is concerned with the mental processes involved in intentional communication. I discuss a few issues that may help clarify the relationship between this area and the broader cognitive science and the contribution that they give, or might give, to each other. Rather than dwelling on the many technicalities of the various theories of communication that have been advanced, I focus on the different conceptions of the nature and the architecture of the mind/brain that underlie them. My aims are, first, to introduce and defend mentalist views of communication in general; second, to defend one such view, namely that communication is a cognitive competence, that is, a faculty, and the underlying idea that the architecture of the mind/brain is domain-specific; and, third, to review the (scarce) neuropsychological evidence that bears on these issues. 相似文献
