This study investigated effects of healthy ageing and of non-verbal attentional control on speech production. Young and older speakers participated in a picture-word interference (PWI) task with compound targets. To increase the processing load, the two pictures of the compounds’ constituents were presented side-by-side for spoken naming (e.g., a picture of a sun + a picture of a flower to be named with sunflower). Written distractors either corresponded to the first or second constituent ( sun or flower → sunflower), or were semantically related either to the first constituent of the target ( moon → sunflower) or to the second constituent/whole word ( tulip → sunflower). Morpho-phonological facilitation was obtained for both constituents, whereas semantic interference was restricted to first-constituent-related semantic distractors. Furthermore, a trend towards facilitation was obtained for distractors that were semantically related to the whole word. Older speakers were slower and produced more errors than young speakers. While morphological effects of first-constituent distractors were stronger for the elderly, the semantic effects were not affected by age. Non-verbal attentional control processes, measured in the Simon task, significantly contributed to morpho-phonological priming in the elderly, but they did not affect semantic interference or semantic facilitation. With a picture naming task that increases the semantic and lexical processing load, we corroborate earlier evidence that word-finding difficulties in the elderly result from deficient phonological encoding, whereas lexical-semantic and morpho-phonological representations remain stable with age.

Naming Tasks

Semantic context effects obtained in naming tasks have been most influential in devising and evaluating models of word production. We re-investigated this effect in the frequently used blocked-cyclic naming task in which stimuli are presented repeatedly either sorted by semantic category (homogeneous context) or intermixed (heterogeneous context). Previous blocked-cyclic naming studies have shown slower picture naming responses in the homogeneous context. Our study compared this context effect in two task versions, picture naming and sound naming. Target words were identical across task versions (e.g., participants responded with the word “dog” to either the picture of that animal or to the sound [barking] produced by it). We found semantic interference in the homogeneous context also with sounds and the effect was substantially larger than with pictures (Experiments 1 and 2). This difference is unlikely to result from extended perceptual processing of sounds as compared to pictures (Experiments 3 and 4) or from stronger links between pictures and object names than between sounds and object names (Experiment 5). Overall, our results show that semantic context effects in blocked-cyclic naming generalize to stimulus types other than pictures and – in part – also reflect pre-lexical processes that depend on the nature of the stimuli used for eliciting the naming responses.

Phonological Complexity

Numerous lexical and sublexical factors have been reported to influence speech production in monolinguals (Storkel, 2001; Vitevitch, 2002); however, whole-word production analyses have rarely been used to measure such influences. The present study investigated the effects of phonotactic probability and neighborhood density on bilingual speech production using whole-word production measures (Ingram, 2002). Five typically developing English–Spanish bilingual children were administered a picture-naming task in English and Spanish in which stimuli varied in sublexical and lexical parameters. Their English and Spanish productions were compared with those of five age-matched monolingual English- and Spanish-speaking children, respectively. No differences were found between bilinguals and monolinguals in the respective languages; however, bilinguals evidenced greater phonological complexity in Spanish than English on words with low phonotactic probability and low neighborhood density. Whole-word approximation remained similar between languages. Findings are interpreted in the context of crosslinguistic influences of sublexical and lexical factors on speech production.

One of the well-documented behavioral changes that occur with advancing age is a decline in executive functioning, for example, attentional control. Age-related executive deficits are said to be associated with a deterioration of the frontal lobes. Neurofeedback is a training method which aims at acquiring self-control over certain brain activity patterns. It is considered as an effective approach to help improve attentional and self-management capabilities. However, studies evaluating the efficacy of neurofeedback training to boost executive functioning in an elderly population are still relatively rare and controversial. The aim of our study was to contribute to the assessment of the efficacy of neurofeedback as a method for enhancing executive functioning in the elderly. We provided a group of seniors with beta up-training (12–22 Hz), consisting of 20 sessions (30 minutes each), on the Cz site and tested its possible beneficiary influence on attentional control assessed by means of the Stroop and Simon tasks. The analysis of the subjects’ mean reaction times during consecutive tasks in the test and the retest, after implementation of neurofeedback training, showed a significant improvement. In contrast, the difference in reaction times between the test and the retest in the control group who had not been submitted to neurofeedback training was not significant.

Objectives: The purpose of this study is to examine the effects of emotions on the confrontation naming of healthy elders and young adults.Methods: The study had a total of 60 subjects (30 elders and 30 young adults). In the confrontation naming task, the researcher asked the subjects to say the name of the picture presented on a screen as quickly and accurately as possible.Results: First, the results of the study showed significantly lower accuracy in the elders compared to the young adults and a significant difference in accuracy according to emotional valence. There was a significant difference between positive and neutral emotional valance and between negative and neutral emotional valance. Additionally, the interaction between the group and emotional valence was statistically significant. The post-hoc test showed that the naming accuracy of the elders was lower than that of the young in the negative emotional valance. Secondly, elders had a longer response time than the young adults. Also, there was a significant difference in response time according to emotional valence. There was a significant difference in response time in three emotional valences (positive, negative, neutral), and the response time increased in neutral < positive < negative. Finally, the interaction between the group and emotional valence was statistically significant, which attributed to the longer response time of the elders compared to the young adults in the positive and negative emotional valance.Conclusion: The study results suggest that emotional valence may interfere with word production, and that such interference may be greater for the elderly than for the young.

The topological organization of the brain, governed by the capacity of brain regions to synchronize their activity, allows for cost-effective performance during everyday cognitive activity. Functional connectivity is an fMRI method deemed task-specific and demand-dependent. Although the brain undergoes significant changes during healthy aging, conceptual knowledge and word-production accuracy are generally preserved. The exploration of task-induced functional connectivity patterns during active picture naming may thus provide additional information about healthy functional cerebral mechanisms that are specifically adapted to the cognitive activity at hand. The goal of this study is to assess and describe age-related differences in functional connectivity during an overt picture-naming task, as well as to compare age-related differences under complex task demand, defined by lexical frequency. Results suggest both age-specific and task-specific mechanisms. In the context of preserved behavioral performance in a picture-naming task, older adults show a complex array of differences in functional connectivity architecture, including both increases and decreases. In brief, there is increased segregation and specialization of regions that are classically assigned to naming processes. Results also expand on previous word-production studies and suggest that motor regions are particularly subject to age-related differences. This study also provides the first indication that intrinsic task demand, as manipulated by lexical frequency, interacts little with the relationship between age and functional connectivity. Together, these findings confirm the value of task-induced functional connectivity analysis in revealing the brain organization that subserves task performance during healthy aging.

This study examined age-related differences in the use of dynamic acoustic information (in the form of formant transitions) to identify vowel quality in CVCs. Two versions of 61 naturally produced, commonly occurring, monosyllabic English words were created: a control version (the unmodified whole word) and a silent-center version (in which approximately 62% of the medial vowel was replaced by silence). A group of normal-hearing young adults (19–25 years old) and older adults (61–75 years old) identified these tokens. The older subjects were found to be significantly worse than the younger subjects at identifying the medial vowel and the initial and final consonants in the silent-center condition. These results support the hypothesis of an age-related decrement in the ability to process dynamic perceptual cues in the perception of vowel quality.

Abstract: Among many other changes, older age is characterized by advanced sleep-wake cycles, changes in the amplitude of various circadian rhythms, as well as reduced entrainment to zeitgebers. These features reveal themselves through early morning awakenings, sleep difficulties at night, and a re-emergence of daytime napping. This review summarizes the observations concerning the biological clock and sleep in the elderly and discusses the documented and theoretical considerations behind these age-related behavioral changes, especially with respect to circadian biology.

Abstract. Results from an affective priming experiment confirm the previously reported influence of trait anxiety on the direction of affective priming in the naming task ( Maier, Berner, & Pekrun, 2003 ): On trials in which extremely valenced primes appeared, positive affective priming reversed into negative affective priming with increasing levels of trait anxiety. Using valenced target words with irregular pronunciation did not have the expected effect of increasing the extent to which semantic processes play a role in naming, as affective priming effects were not stronger for irregular targets than for regular targets. This suggests the predominant operation of a whole-word nonsemantic pathway in reading aloud in German. Data from neutral priming trials hint at the possibility that negative affective priming in participants high in trait anxiety is due to inhibition of congruent targets.
