Purpose We investigated whether impaired acoustic processing is a factor in developmental language disorders. The amplitude envelope of the speech signal is known to be important in language processing. We examined whether impaired perception of amplitude envelope rise time is related to impaired perception of lexical and phrasal stress in children with specific language impairment (SLI). Method Twenty-two children aged between 8 and 12 years participated in this study. Twelve had SLI; 10 were typically developing controls. All children completed psychoacoustic tasks measuring rise time, intensity, frequency, and duration discrimination. They also completed 2 linguistic stress tasks measuring lexical and phrasal stress perception. Results The SLI group scored significantly below the typically developing controls on both stress perception tasks. Performance on stress tasks correlated with individual differences in auditory sensitivity. Rise time and frequency thresholds accounted for the most unique variance. Digit Span also contributed to task success for the SLI group. Conclusions The SLI group had difficulties with both acoustic and stress perception tasks. Our data suggest that poor sensitivity to amplitude rise time and sound frequency significantly contributes to the stress perception skills of children with SLI. Other cognitive factors such as phonological memory are also implicated.

Amplitude rise times play a crucial role in the perception of rhythm in speech, and reduced perceptual sensitivity to differences in rise time is related to developmental language difficulties. Amplitude rise times also play a mechanistic role in neural entrainment to the speech amplitude envelope. Using an ERP paradigm, here we examined for the first time whether infants at the ages of seven and eleven months exhibit an auditory mismatch response to changes in the rise times of simple repeating auditory stimuli. We found that infants exhibited a mismatch response to the oddball rise time that was more positive at seven than eleven months of age. At eleven months, there was a left-lateralised shift to a mismatch negativity. Infants’ ability to detect changes in rise time was generally robust, with a range of oddball stimuli with different rise times each eliciting a mismatch response from 85% of infants. A lateralised effect indicated that the size of the mismatch response varied as the change in rise time became easier to detect. The mismatch response to the different rise time oddballs also stabilised as infants got older. The results indicate that neural processing of changes in rise time develops early in life, supporting the possibility that early speech processing is facilitated by neural sensitivity to these acoustic cues to rhythm.

<b><i>Background/Aims:</i></b> Studies of people with dyslexia have pointed to the ability to perceive the amplitude envelope rise time (“beat” perception) as a possible cause of phonological processing (PhP) difficulties in this population. However, there are very few studies about the relationships between such skills in the non-dyslexic school population. <b><i>Methods:</i></b> We investigated the influence of the beat perception ability on PhP and reading skills of 93 Brazilian Portuguese-speaking schoolchildren from the 3rd to the 5th year, with data on reading, phonological awareness (PhA), lexical access, phonological operational memory, and perception of amplitude envelope rise time. To verify the possible effects of age, gender, and school grade on the tasks in the study, we directly included these variables in the models. <b><i>Results:</i></b> Modeling structural equations showed that beat perception did not influence PhP or reading skills, but only the tasks of repetition of words and pseudowords. These tasks may be related because of the demand for phonological working memory necessary to perform the beat perception task rather than a possible connection between this and phonological abilities, as reported in the literature. <b><i>Conclusion:</i></b> We suspect beat perception could be of relevance only for subjects with altered reading and/or a deficit in PhP. Further studies will indicate whether the rise time of the amplitude envelope is an essential acoustic clue only for those individuals whose PhA ability is not fully present.

This investigation examined the degree to which modification of the consonant-vowel (C-V) intensity ratio affected consonant recognition under conditions in which listeners were forced to rely more heavily on waveform envelope cues than on spectral cues. The stimuli were 22 vowel-consonant-vowel utterances, which had been mixed at six different signal-to-noise ratios with white noise that had been modulated by the speech waveform envelope. The resulting waveforms preserved the gross speech envelope shape, but spectral cues were limited by the white-noise masking. In a second stimulus set, the consonant portion of each utterance was amplified by 10 dB. Sixteen subjects with normal hearing listened to the unmodified stimuli, and 16 listened to the amplified-consonant stimuli. Recognition performance was reduced in the amplified-consonant condition for some consonants, presumably because waveform envelope cues had been distorted. However, for other consonants, especially the voiced stops, consonant amplification improved recognition. Patterns of errors were altered for several consonant groups, including some that showed only small changes in recognition scores. The results indicate that when spectral cues are compromised, nonlinear amplification can alter waveform envelope cues for consonant recognition.

Abstract. Background: Several studies found a significant relationship between important sport events and suicidal behavior. Aims: We set out to investigate whether there is a significant relationship between the raw suicide rate and the most important international sports events (Olympic Games, FIFA World Cup, UEFA European Championship) in such an achievement-oriented society as the Hungarian one, where these sport events receive great attention. Method: We examined suicide cases occurring over 15,706 days between January 1, 1970, and December 31, 2012 (43 years), separately for each gender. Because of the age-specific characteristics of suicide, the effects of these sport events were analyzed for the middle-aged (30–59 years old) and the elderly (over 60 years old) generations as well as for gender-specific population groups. The role of international sport events was examined with the help of time-series intervention analysis after cyclical and seasonal components were removed. Intervention analysis was based on the ARIMA model. Results: Our results showed that only the Olympic Games had a significant effect in the middle-aged population. Neither in the older male nor in any of the female age groups was a relationship between suicide and Olympic Games detected. Conclusion: The Olympic Games seem to decrease the rate of suicide among middle-aged men, slightly but significantly.

The Draw-A-Person (DAP) test has been the center of a long-lasting debate regarding its validity. This study investigated the DAP indices of height, width (size), and inclusion/omission of details and their relation to body image as measured by a self-report scale (Gray’s body image scale) and manifested by the diet behaviors and body mass index of 55 healthy female students. Although the drawings of the diet group were smaller, there was no significant relationship between figure size and diet behaviors. However, body image as measured by a self-report scale did result in significant differences between groups. Moreover, there was a significant correlation between the size of the figure drawn and body image as measured by a self-report scale (larger figures correlated with better body image). No significant results were found for the omission/inclusion indices of the DAP. These results are discussed in light of previous findings regarding the DAP.

SummaryThe validity of a previously described technique for predicting warfarin requirements based on the anticoagulant response to a fixed loading dose was assessed prospectively in 57 patients. There was a close relationship between the predicted and initially observed daily warfarin dose required to maintain the patient within the therapeutic range for anticoagulation. The significant relationship between predicted and observed maintenance dose persisted at 4 and 12 weeks although it decreased with increasing time.The relationship between observed and predicted maintenance requirement of warfarin was not affected by the concomitant use of intermittent intravenous injections of heparin when 9 hr was allowed to elapse between the previous dose of heparin and the thrombotest estimation on which the prediction was based.It is concluded that the method is valuable in predicting an individual’s warfarin requirement, although it does not obviate the need for regular monitoring of anticoagulant control.
