A common assumption is that phonetic sounds initiate unique processing in the superior temporal gyri and sulci (STG/STS). The anatomical areas subserving these processes are also implicated in the processing of non-phonetic stimuli such as music instrument sounds. The differential processing of phonetic and non-phonetic sounds was investigated in this study by applying a “sound-morphing” paradigm, where the presence of phonetic features were parametrically varied, creating a step-wise transition from a non-phonetic sound into a phonetic sound. The stimuli were presented in an event-related fMRI design. The fMRI-BOLD data were analysed using parametric contrasts. The results showed a higher sensitivity for sounds containing phonetic features compared to non-phonetic sounds in the middle part of STG, and in the anterior part of the planum temporale (PT) bilaterally. Although the same areas were involved in the processing of non-phonetic sounds, a difference in activation was evident in the STG, with an increase in activation related to increment of phonetic features in the sounds. The results indicate a stimulus-driven, bottom-up process that utilizes general auditory resources in the secondary auditory cortex, depending on specific phonetic features in the sounds. 相似文献

Within the framework of Friederici’s (2002) neurocognitive model of sentence processing, the early left anterior negativity (ELAN) in event-related potentials (ERPs) has been claimed to be a brain marker of syntactic first-pass parsing. As ELAN components seem to be exclusively elicited by word category violations (phrase structure violations), they have been taken as strong empirical support for syntax-first models of sentence processing and have gained considerable impact on psycholinguistic theory in a variety of domains. The present article reviews relevant ELAN studies and raises a number of serious issues concerning the reliability and validity of the findings. We also discuss how baseline problems and contextual factors can contribute to early ERP effects in studies examining word category violations. We conclude that - despite the apparent wealth of ELAN data - the functional significance of these findings remains largely unclear. The present paper does not claim to have falsified the existence of ELANs or syntax-related early frontal negativities. However, by separating facts from myths, the paper attempts to make a constructive contribution to how future ERP research in the area of syntax processing may better advance our understanding of online sentence comprehension. 相似文献

Abstract This paper compares and contrasts the experiences of two different long term psychodynamic psychotherapy groups in which a patient suicided. The acute reactions and longer term process of each group is described in detail and discussed. The reactions of the two leaders, married to each other and in a shared supervisory group with the late Anne Alonso, and their own working through of the traumatic losses are explored. Their experiences highlight the importance of open discussion of the suicides in the groups, consultation with senior colleagues, and continual processing of their own reactions as a means of fostering posttraumatic growth. The authors discuss their experience in light of the literature on trauma in groups and the emerging literature on posttraumatic growth and they reflect on implications for the community of group therapists. 相似文献

Background. Chronotype refers to individuals’ preference for morning or evening activities. Its two dimensions (morningness and eveningness) are related to a number of academic outcomes. Aims. The main goal of the study was to investigate the incremental validity of chronotype as a predictor of academic achievement after controlling for a number of traditional predictors. In so doing, a further aim was ongoing validation of a chronotype questionnaire, the Lark‐Owl Chronotype Indicator. Sample. The sample comprised 272 students attending 9th and 10th grades at five German high schools. Data was also obtained from 132 parents of these students. Method. Students were assessed in class via self‐report questionnaires and a standardized cognitive test. Parents filled out a questionnaire at home. The incremental validity of chronotype was investigated using hierarchical linear regression. Validity of the chronotype questionnaire was assessed by correlating student ratings of their chronotype with behavioural data on sleep, food intake, and drug consumption and with parent ratings of chronotype. Results. Eveningness was a significant (negative) predictor of overall grade point average (GPA), math–science GPA, and language GPA, after cognitive ability, conscientiousness, need for cognition, achievement motivation, and gender were held constant. Validity evidence for the chronotype measure was established by significant correlations with parent‐ratings and behavioural data. Conclusions. Results point to the possible discrimination of adolescents with a proclivity towards eveningness at school. Possible explanations for the relationship between chronotype and academic achievement are presented. Implications for educational practice are also discussed. 相似文献

Reciprocal conversations, instructional activities, and other social interactions are replete with multiply controlled intraverbals, examples of which have been conceptualized in terms of conditional discriminations. Although the acquisition of conditional discriminations has been examined extensively in the behavior‐analytic literature, little research has evaluated procedures to establish multiply controlled intraverbals. Thus, the purpose of this investigation was to evaluate the effects of procedures based on conditional discrimination training on the acquisition of multiply controlled intraverbals with 7 participants who had been diagnosed with autism spectrum disorders. We evaluated the effects of prompt delay with error correction, a differential observing response (DOR), and a DOR plus blocked trials on the acquisition of intraverbals using a multiple baseline design. Accuracy of intraverbal performance increased for at least 1 set of stimuli for all participants under prompt delay with error correction conditions; however, 4 participants required additional teaching (i.e., DOR, modified DOR, modified prompt delay with error correction). Based on these findings, when prompt delay with error correction is not sufficient to establish multiply controlled intraverbals, prompted DORs may be an effective alternative. 相似文献

The present study investigated whether unemployment influences the importance and the realization of life goals and whether a reduced realization of life goals mediates the negative effect of unemployment on subjective well-being. A sample of 256 employed and unemployed German adults was studied with scales measuring six different life goal domains (power, achievement, variety, altruism, intimacy, affiliation). Only weak differences between unemployed and employed people were found for importance ratings of life goals. However, current realization of life goals, particularly of agency goals such as power, achievement and variety, was significantly lower among unemployed persons than among employed persons. Thus, unemployment did not change the goals people wanted to achieve in their lifetime, but it inhibited the success of these strivings. Furthermore, current realization of life goals was found to be a mediator of the detrimental effect of unemployment on life satisfaction and positive/negative affect. 相似文献

Cette recherche a examiné la validité d'un centre d'évaluation pour la sélection de pilotes. Les scores de N = 1,036 participants ont été utilisés pour étudier la validité de construit. Un sous-échantillon de participants performants a été suivi et les évaluations des pairs ont été retenus comme mesures du critère. Les résultats démontrent une première évidence de validité de construit et de critère pour cet outil d'évaluation des compétences interpersonnelles et liées à la performance. Par ailleurs, les résultats ont aussi montré que le type d'évaluateur (psychologue vs pilote) modère la validité prédictive des scores du centre d'évaluation. Cet effet "type d'évaluateur" dépend de la sorte de variables prédictives. Les résultats sont discutés et des implications pratiques sont suggérées.
This study examined the validity of an assessment center in pilot selection as a new field of application. Assessment center ratings of N = 1,036 applicants were used to examine the construct validity. A subsample of successful applicants was followed up and peer ratings were chosen as criterion measures. The results provide first evidence of the construct and criterion validity of this assessment center approach for rating interpersonal and performance-related skills. Furthermore the type of assessor (psychologist versus pilot) moderates the predictive validity of the assessment center ratings. This type-of-assessor effect depends on the kind of predictor variables. The results are discussed and practical implications are suggested. 相似文献

Embodied cognition postulates a bi-directional link between the human body and its cognitive functions. Whether this holds for higher cognitive functions such as problem solving is unknown. We predicted that arm movement manipulations performed by the participants could affect the problem-solving solutions. We tested this prediction in quantitative reasoning tasks that allowed two solutions to each problem (addition or subtraction). In two studies with healthy adults (N?=?53 and N?=?50), we found an effect of problem-congruent movements on problem solutions. Consistent with embodied cognition, sensorimotor information gained via right or left arm movements affects the solution in different types of problem-solving tasks. 相似文献
