Most people would agree that facing goal conflict is a negative experience. However, many, but not all empirical studies actually show a negative relationship between goal conflicts and well-being: goal conflicts apparently differ in their effects. The aim of the present study was to investigate the role of the level of goal self-concordance (i.e., to what extent goals are pursued with self-determined motivation) for people’s affective reactions to goal conflicts due to resource constraints. Analyses of goal conflicts experienced at work by N = 647 junior scientists shed light onto the role of levels of self-concordance of the conflicting goals on the way the goal conflict is experienced. Results show that goal self-concordance explains variance in affective reaction beyond goal importance and goal attainability. More specifically, conflicts between two goals with high levels of self-concordance are associated to rather positive affect (e.g., excited). In contrast, conflicts between two goals with low levels of self-concordance are associated to rather negative affect (e.g., frustrated). Overall, these results emphasize the need to consider goal properties in future research on goal conflicts.  相似文献

Implicit learning is a process of acquiring knowledge that occurs without conscious awareness of learning, whereas explicit learning involves the use of overt strategies. To date, research related to implicit learning following stroke has been largely restricted to the motor domain and has rarely addressed implications for language. The present study investigated implicit and explicit learning of an auditory word sequence in 10 individuals with stroke-induced agrammatic aphasia and 18 healthy age-matched participants using an adaptation of the Serial Reaction Time task. Individuals with aphasia showed significant learning under implicit, but not explicit, conditions, whereas age-matched participants learned under both conditions. These results suggest significant implicit learning ability in agrammatic aphasia. Furthermore, results of an auditory sentence span task indicated working memory deficits in individuals with agrammatic aphasia, which are discussed in relation to explicit and implicit learning processes.  相似文献

Mind wandering reduces both the sensory and cognitive processing of affectively neutral stimuli, but whether it also modulates the processing of affectively salient stimuli remains unclear. In particular, we examined whether mind wandering attenuates one’s sensitivity to observing mild pain in others. In the first experiment, we recorded event-related potentials (ERPs) as participants viewed images of hands in either painful or neutral situations, while being prompted at random intervals to report whether their thoughts were on task or mind wandering. We found that the brain’s later response to painful images was significantly reduced immediately preceding “mind-wandering” versus “on-task” reports, as measured via amplitude decreases in a frontal–central positivity beginning approximately 300 ms poststimulus. In a second, control experiment using behavioral measures, we wanted to confirm whether the subjective sense of pain observed in others does in fact decrease during mind wandering. Accordingly, we asked participants to rate how painful the hand images looked on a 5-point Likert scale, again while taking reports of their mind-wandering states at unpredictable intervals. Consistent with our ERP data, we found that the ratings for painful images were significantly reduced immediately preceding mind-wandering reports. Additional control analyses suggested that the effect could not simply be ascribed to general habituation in the affective response to painful images over time. Collectively, our findings demonstrate that mind wandering can directly modulate the cortical processing of affectively salient stimulus inputs, serving in this case to reduce sensitivity to the physical discomfort of others.  相似文献

A widely agreed-upon feature of spoken word recognition is that multiple lexical candidates in memory are simultaneously activated in parallel when a listener hears a word, and that those candidates compete for recognition (Luce, Goldinger, Auer, & Vitevitch, Perception 62:615–625, 2000; Luce & Pisoni, Ear and Hearing 19:1–36, 1998; McClelland & Elman, Cognitive Psychology 18:1–86, 1986). Because the presence of those competitors influences word recognition, much research has sought to quantify the processes of lexical competition. Metrics that quantify lexical competition continuously are more effective predictors of auditory and visual (lipread) spoken word recognition than are the categorical metrics traditionally used (Feld & Sommers, Speech Communication 53:220–228, 2011; Strand & Sommers, Journal of the Acoustical Society of America 130:1663–1672, 2011). A limitation of the continuous metrics is that they are somewhat computationally cumbersome and require access to existing speech databases. This article describes the Phi-square Lexical Competition Database (Phi-Lex): an online, searchable database that provides access to multiple metrics of auditory and visual (lipread) lexical competition for English words, available at www.juliastrand.com/phi-lex.  相似文献

Mitochondrial next generation sequencing (NGS) panels offer single-step analysis of the numerous nuclear genes involved in the structure, function, and maintenance of mitochondria. However, the complexities of mitochondrial biology and genetics raise points for consideration in clinical use of these tests. To understand the current status of mitochondrial genetic testing, we assessed the gene offerings and consent forms of mitochondrial NGS panels available from seven US-based clinical laboratories. The NGS panels varied markedly in number of genes (101–1204 genes), and the proportion of genes causing “classic” mitochondrial diseases and their phenocopies ranged widely between labs (18 %–94 % of panel contents). All panels included genes not associated with classic mitochondrial diseases (6 %–28 % of panel contents), including genes causing adult-onset neurodegenerative disorders, cancer predisposition, and other genetic syndromes or inborn errors of metabolism. Five of the panels included genes that are not listed in OMIM to be associated with a disease phenotype (5 %–49 % of panel contents). None of the consent documents reviewed had options for patient preference regarding receipt of incidental findings. These findings raise points of discussion applicable to mitochondrial diagnostics, but also to the larger arenas of exome and genome sequencing, including the need to consider the boundaries between clinical and research testing, the necessity of appropriate informed consent, and the responsibilities of clinical laboratories and clinicians. Based on these findings, we recommend careful evaluation by laboratories of the genes offered on NGS panels, clear communication of the predicted phenotypes, and revised consent forms to allow patients to make choices about receiving incidental findings. We hope that our analysis and recommendations will help to maximize the considerable clinical utility of NGS panels for the diagnosis of mitochondrial disease.  相似文献

Perceptual decisions seem to be made automatically and almost instantly. Constructing a unitary subjective conscious experience takes more time. For example, when trying to avoid a collision with a car on a foggy road you brake or steer away in a reflex, before realizing you were in a near accident. This subjective aspect of object recognition has been given little attention. We used metacognition (assessed with confidence ratings) to measure subjective experience during object detection and object categorization for degraded and masked objects, while objective performance was matched. Metacognition was equal for degraded and masked objects, but categorization led to higher metacognition than did detection. This effect turned out to be driven by a difference in metacognition for correct rejection trials, which seemed to be caused by an asymmetry of the distractor stimulus: It does not contain object-related information in the detection task, whereas it does contain such information in the categorization task. Strikingly, this asymmetry selectively impacted metacognitive ability when objective performance was matched. This finding reveals a fundamental difference in how humans reflect versus act on information: When matching the amount of information required to perform two tasks at some objective level of accuracy (acting), metacognitive ability (reflecting) is still better in tasks that rely on positive evidence (categorization) than in tasks that rely more strongly on an absence of evidence (detection).  相似文献

Counselors’ decision‐making processes have received little attention in the literature. The purpose of this study was to ascertain the ethical decision‐making practices of counselors working in the field. The results of a phenomenological study indicate that linear models and an orientation to professional ethical guidelines learned in graduate training serve as a foundation, yet not a practical guide, in professional ethical decision making. The authors found that 4 themes guide counselors’ ethical decision making: personal values, clients’ best interest, transparency in decision making, and perceptions of formal training and practice. Implications for practice and counselor education are provided, with recommendations for future research.  相似文献
