Auditory masking effects on lingual vibrotactile thresholds were examined across three groups of 10 subjects each. The first group included children 13 yr. of age or younger, the second group young college age adults, and the third group elderly individuals 66 yr. of age or older. Lingual vibrotactile thresholds were obtained from each group at a frequency of 250 Hz, under experimental conditions of no-masking, narrow-band masking, and wide-band masking. Results showed statistically significant threshold differences between the elderly group and the other two groups for all three experimental conditions. A difference was also detected between experimental conditions when an over-all statistical analysis was performed, but this difference disappeared under more stringent post hoc examination. Results are discussed with respect to current literature on aging and appropriate simplified procedures are recommended for future lingual vibrotactile threshold testing.

Vibrotactile Thresholds

Effects of duration of stimulus exposure on lingual vibrotactile thresholds were examined across three groups of 10 subjects each ( n = 30). Subjects were grouped according to age (child group, mean age = 10.1 yr.; young adult group, mean age = 21.9 yr.; elderly group, mean age = 76.0 yr.). Lingual vibrotactile threshold measurements were obtained for all subjects under 5 conditions of exposure (1, 2, 3, 4, and 5 sec.). Results showed statistically significant differences in threshold among all three age groups. As age increased, thresholds of lingual sensitivity increased (became poorer). Stimulus duration also created significant differences in threshold for all age groups. As stimulus duration increased, thresholds of lingual sensitivity decreased (became better). The children appeared to be the most stable across conditions whereas the elderly group appeared to be the most affected by stimulus duration.

Auditory interaction effects on lingual vibrotactile thresholds were examined for 20 adult subjects. The thresholds from two different masking conditions were compared to the thresholds from a no-masking condition for three different frequencies. Results showed no auditory interference on obtained thresholds for any condition with any frequency. Future research endeavors are discussed with respect to gaining a more complete understanding of auditory interactions in lingual vibrotactile threshold measurement.

Auditory masking has become a frequently employed part of the procedure used in vibrotactile research. Research investigating the effect of auditory masking on lingual vibrotactile thresholds of sensitivity has shown that there is little difference between lingual vibrotactile thresholds under masking and no masking conditions. The purpose of the present study was to extend the investigation of the effect of auditory masking to include lingual vibrotactile suprathreshold scaling responses. 20 young adult subjects of mean age 19 yr. completed lingual vibrotactile-threshold and magnitude-estimation scaling tasks under conditions of bilateral auditory masking and no masking. Similar lingual vibrotactile-threshold values and magnitude-estimation power-function exponents for the conditions of masking and no masking were noted.

Classifying CPs within the overly vague, uninformative category “suprasellar” prevents gaining any true insight regarding the risks associated with the surgical procedure employed. Routine MRI obtained with conventional T1- and T2-weighted sequences along the midsagittal and coronal trans-infundibular planes allow an accurate and reliable preoperative definition of CP topography. CPs developing primarily within the infundibulum and/or tuberal region of the hypothalamus, as well as those wholly located within the 3V, should be distinguished preoperatively from those lesions originally expanding beneath the 3V floor (3VF), the true suprasellar tumors. Among adult patients, about 40% of CPs correspond to infundibulo-tuberal tumors expanding primarily within the 3VF, above an intact pituitary gland and stalk. This subgroup of CPs shows strong adherences to the surrounding hypothalamus, as they are embedded within a wide band of reactive gliotic tissue, usually infiltrated by microscopic finger-like solid cords of tumor tissue. In elderly patients, a significant proportion of CPs correspond to papillary tumors developing above an intact 3VF, usually showing small pedicle-like or sessile-like attachments to the infundibulum. With the current diagnostic MRI workup routinely employed for CPs, it is possible, for the majority of lesions, to preoperatively differentiate these topographical variants and predict the type of CP-hypothalamus relationship that will be found during surgery.

RESUMO Objetivo Avaliar, por meio de questionários padronizados, a qualidade de vida de idosos com deficiência auditiva diagnosticada que utilizam ou não a prótese auditiva (AASI) e de idosos sem queixa auditiva. Método Trata-se de um estudo transversal, com amostra não probabilística, distribuída em três grupos divididos da seguinte forma: 30 idosos com perda auditiva diagnosticada e com indicação para uso do aparelho de amplificação sonora individual (AASI), mas que ainda não faziam uso da prótese; 30 idosos com deficiência auditiva que usavam o AASI; e 30 idosos sem queixa auditiva. Os participantes completaram um questionário que investigava dados sociodemográficos e familiares, o Hearing Handicap Inventory for the Elderly Screening Version (HHIE-S) e o World Health Organization Quality of Life - versão breve (WHOQOL-Breve). Além das análises descritivas dos dados, foram realizados testes para comparação dos três grupos, aplicando-se a análise de variância (ANOVA) e o teste post hoc de Bonferroni. Resultados Os três grupos se diferenciaram significativamente em todos os domínios de qualidade de vida. O grupo de idosos com perda auditiva diagnosticada e com indicação para uso do AASI apresentou menores escores que o grupo de idosos com deficiência auditiva que usavam o AASI e que o grupo de referência. O grupo com AASI apresentou os melhores resultados de qualidade de vida. Conclusão A perda auditiva afeta a qualidade de vida do idoso. O uso efetivo da prótese auditiva é benéfico a esta população, melhorando suas condições de vida e saúde.

Purpose The purpose of this paper is to address an overarching question: Does matching consumer place–brand associations with stereotype-consistent messaging affect consumer perceptions of an advertisement? Design/methodology/approach This paper presents two experiments that examine participants’ differing evaluations of advertisements under various experimental conditions. Study 1 examines the match of place–brand warmth versus competence stereotypes and the use of symbolic versus utilitarian advertising messaging for both new foreign and domestic brands. Study 2 examines this match for global brands. Findings The paper reveals that stereotype-consistent messaging increases the perceived fit between the advertisement and the brand for new foreign brands but not for new domestic or global brands. Furthermore, in a post-hoc analysis, this congruence is found to improve attitude towards the brand, purchase intentions and brand response, through the mediating effect of attitude towards the ad. Originality/value Place–brand stereotypes impact consumer attitudes and opinions regarding brands from different countries. This paper applies two universal social judgment dimensions from social psychology—warmth and competence—to the novel context of advertising messaging to examine previously unexplored facets of the place–brand image.

A series of experiments was performed to study the upward-spread-of-masking phenomena as it pertains to pure-tone and speech stimuli. In the initial two experiments, three maskers were employed over a 40–60-dB intensity range. They included a wide band (50–5500 Hz), a speech spectrum (50–1000 Hz), and a narrow-band (50–950 Hz) noise. All filter slopes were 48 dB/octave, except for the upper slope of the speech-spectrum noise that was 6 dB/octave. In the first experiment, pure-tone thresholds obtained by a tracking procedure revealed no spread of masking when the wide-band and speech-spectrum maskers were used. Substantial spread-of-masking effects, characterized by nonlinear threshold increments outside the spectrum of the masker, were observed with the narrow-band masker. The second experiment included three types of speech stimuli (PBs, spondees, and synthetic sentences) under the same mask conditions used with the pure tones. Threshold shifts observed for the wide- and speech-spectrum maskers were linear with the masking intensity level. However, increased shifts, attributable to spread of masking, were observed with the narrow band and progressed nonlinearly as a function of the masking level. Finally, two additional experiments, performed with two different narrow-band maskers and spondee words, provided insightful information regarding the effects of the spread of masking on speech stimuli.

As the elderly population grows worldwide, living a healthy and full life as an older adult is becoming a topic of great interest. One key factor and severe challenge to maintaining quality of life in older adults is cognitive decline. Assistive robots for helping older adults have been proposed to solve issues such as social isolation and dependent living. Only a few studies have reported the positive effects of dialogue robots on cognitive function but conversation is being discussed as a promising intervention that includes various cognitive tasks. Existing dialogue robot-related studies have reported on placing dialogue robots in elderly homes and allowing them to interact with residents. However, it is difficult to reproduce these experiments since the participants’ characteristics influence experimental conditions, especially at home. Besides, most dialogue systems are not designed to set experimental conditions without on-site support. This study proposes a novel design method that uses a dialogue-based robot system for cognitive training at home. We define challenges and requirements to meet them to realize cognitive function training through daily communication. Those requirements are designed to satisfy detailed conditions such as duration of dialogue, frequency, and starting time without on-site support. Our system displays photos and gives original stories to provide contexts for dialogue that help the robot maintain a conversation for each story. Then the system schedules dialogue sessions along with the participant’s plan. The robot moderates the user to ask a question and then responds to the question by changing its facial expression. This question-answering procedure continued for a specific duration (4 min). To verify our design method’s effectiveness and implementation, we conducted three user studies by recruiting 35 elderly participants. We performed prototype-, laboratory-, and home-based experiments. Through these experiments, we evaluated current datasets, user experience, and feasibility for home use. We report on and discuss the older adults’ attitudes toward the robot and the number of turns during dialogues. We also classify the types of utterances and identify user needs. Herein, we outline the findings of this study, outlining the system’s essential characteristics to experiment toward daily cognitive training and explain further feature requests.

Objective: To verify the effect of recreational soccer on bone mineral density and sarcopenia in the elderly. Methods: Fourteen elderly people aged 65.9 ± 3.4 years were selected. They were separated into two groups: the intervention group and the control group; the intervention group played recreational soccer for 12 weeks on two days of the week. Assessments were performed for bone mineral density and body muscle mass before and after the intervention. For statistical analysis, the repeated measures ANOVA with Bonferroni’s post hoc test was used. Results: After 12 weeks, there was a significant change in bone mineral density in the region of the total femur (p = 0.020). Analyzing the participants’ sarcopenia, no significant results were found after the intervention period. Conclusion: Playing recreational soccer causes a significant improvement in the total femur and maintains bone regions in the spine, whole body, and femoral neck. Also, it promotes a removal from the threshold for sarcopenia screening in the elderly.
