In older adults, difficulties processing complex auditory scenes, such as speech comprehension in noisy environments, might be due to a specific impairment of temporal processing at early, automatic processing stages involving auditory sensory memory (ASM). Even though age effects on auditory temporal processing have been well-documented, there is a paucity of research on how ASM processing of more complex tone-patterns is altered by age. In the current study, age effects on ASM processing of temporal and frequency aspects of two-tone patterns were investigated using a passive listening protocol. The P1 component, the mismatch negativity (MMN) and the P3a component of event-related brain potentials (ERPs) to tone frequency and temporal pattern deviants were recorded in younger and older adults as a measure of auditory event detection, ASM processing, and attention switching, respectively. MMN was elicited with smaller amplitude to both frequency and temporal deviants in older adults. Furthermore, P3a was elicited only in the younger adults. In conclusion, the smaller MMN amplitude indicates that automatic processing of both frequency and temporal aspects of two-tone patterns is impaired in older adults. The failure to initiate an attention switch, suggested by the absence of P3a, indicates that impaired ASM processing of patterns may lead to less distractibility in older adults. Our results suggest age-related changes in ASM processing of patterns that cannot be explained by an inhibitory deficit. 相似文献

Emotion dysregulation in Borderline Personality Disorder (BPD) is characterized by high baseline negative intensity, high reactivity, and slow return to baseline. Patients with BPD often engage in self-injurious behavior because it leads to immediate relief of stress levels. We aimed to assess stress regulation as well as the influence of tissue damage on subjective (aversive tension) and objective (heart rate) stress correlates in BPD. In 14 unmedicated patients with BPD and 18 healthy controls, a stress induction was followed by an incision into the forearm conducted by an investigator. For aversive tension, we found elevated baseline levels as well as slower return to baseline in BPD. In controls, incision resulted in a short-term increase of aversive tension, whereas tension and heart rate decreased in the BPD group. Our preliminary results support the hypothesis that tissue damage may play a role in disturbed stress regulation in BPD. 相似文献

Judges often evaluate stimulus series on dimensions for which no physical scale exists; for example, when judging academic ability in oral examinations. We propose that judges deal with this problem by calibrating an internal judgment scale that maps stimulus input onto available judgment categories. This calibration process implies serial position effects: Judges should initially avoid extreme categories, because using extreme categories reduces judgmental degrees of freedom, thereby increasing the possibility of internal consistency violations. In four experiments, we show that judgments become indeed more extreme later in a series of judgments. Judges evaluated the same good (poor) performances more positive (negative) at the end of a sequence compared to the beginning. Judges’ expertise did not prevent the effect, but allowing end-of-sequence judgments reduced serial position effects. We discuss the implications and possible remedies of these calibration effects on judgment extremity. 相似文献

An increasing number of genetic counselors are moving into non-clinical roles, where their primary duties do not involve direct patient contact. According to the National Society of Genetic Counselors Professional Status Survey in 2010, 23% of counselors working in non-clinical roles identified laboratory or genetic testing as their primary area of work. Using a survey, we identified 43 genetic counselors who work predominately in laboratory settings. The two primary tasks performed by participants, include acting as a customer liaison (95%) and calling out test results (88%). Nineteen participants (44.2%) also reported spending a considerable amount of time signing reports. The most prevalent areas of job satisfaction were support from laboratory directors (76.8%), autonomy (76.7%), interactions with clinicians (69.7%) and interaction with other genetics counselors (67.5%). This is the first study specifically looking at the roles of laboratory genetic counselors, which is an expanding area of genetic counseling. 相似文献

In a late notation from 1932, Husserl emphasizes the fact that a broad concept of ??apperception?? should also include, alongside his usual examples, the apprehension of objects as bearers of an individual or inter-subjective past, specifically ??indicated?? with them; thus, he distinguishes between apperceptions ??appresenting?? a simultaneous content (co-presentations), anticipatory apperceptions pointing to future incidents, and retrospective apperceptions referring to ??ad-memorized?? (hinzuerinnert, ad-memoriert) features and events. The latter sort of apperceptions are involved not only in our apprehension of historical traces and relics, but also in that of causal relations, familiar objects, and cultural objects in general. Following several later notations of Husserl concerning the topic of ??apperceptions,?? this paper outlines the specific intentional structure of retrospective or evocative apperceptions, analyzing their various possible forms. 相似文献

Almost 20?years ago, Jürgen Habermas launched the idea of constitutional patriotism as a proposed solution to the tension between citizenship and national identity in the European Union. Since then, constitutional patriotism has remained a key concept in debates on European Union (EU) citizenship and democracy. This article, as so many before it, scrutinizes the meaning and viability of the concept. Unlike most others, however, it focuses less on the content of the concept and more on the subjects to which it is assumed/supposed to apply. I argue, firstly, that constitutional patriotism is not a viable or even desirable ideal for the European demos in its totality. The potential patriots of the EU are not the large majority of European Union citizens who live in their home country but migrants from other member states and nonmember states who are foreigners in their host countries. Secondly and accordingly, I argue that advancing constitutional patriotism means improving the status of foreign nationals in general and third-country nationals in particular. Connecting the acquisition of EU citizenship to domicile as opposed to member state nationality is one venue for such improvement. I discuss what this could imply and defend it as a means of building a truly European demos. 相似文献
