Listening to speech while retaining music: What happens to the right-ear advantage?

On each trial, subjects were played a dichotic pair of syllables differing in the consonant (/ba/, /da/, /ga/) or in the vowel (/ba/, /b?/, /bi/). The pair of syllables was preceded by a melody, or a sentence, and followed by the same or a different melody, or sentence. Subjects either had to retain the first piece of additional material or were free to ignore it. The different combinations of phonemic contrast, additional material, and instruction concerning the additional material were used in different sessions. In each case, the main task of the subjects was to respond to the presence or the absence of the target /ba/ on the ear previously indicated. There was no effect of context on relative ear accuracy, but the right-ear advantage observed for consonants in response latency when subjects retained a sentence gave way to a small nonsignificant left-ear advantage when subjects retained a melody. Right-ear advantage in response latencies was also observed for vowels in the verbal context, but the contextual effect, although in the same direction as for consonants, was very slight. The implications of contextual effects for a theory of the determinants of the auditory laterality effects are discussed.

Humor and coping with stress: A test under real-life conditions

The relationship between humor and coping with stress was investigated for trainees in a course for combat NCOs in the Israel Defense Forces. Measures of humor through self-report and peer-ratings were administered to 159 soldiers. Coping with stress was assessed through ratings by commanders and peers, and through final course grades. The findings showed that humor as rated by peers (but not by self-report) was positively related to performance under stress. This was especially true for active humor (self-produced as opposed to reactive humor). No differences were found between individuals characterized by self-directed humor and other-directed humor in performance under stress. The implications in terms of humor theories and further research are discussed.     

Testing the Situationism Scale in Europe: Scale validation,self‐regulation and regional differences

The term situationism refers to an individual's belief about the importance of a behaviour's context. This study tested whether the degree of situationism expressed by individuals in various regions of Europe was consistent with self‐regulation and cross‐cultural theories. The English version of a Situationism Scale (measuring beliefs about the relation between the environment and one's own behaviour) was translated into five additional languages: Dutch, German, Hungarian, Italian and Slovenian. Young adults (N = 1106, M_Age = 22.9 years, 79% female) across Europe responded to one of the six language versions of the scale as part of a larger survey. Results indicated that: new language versions were psychometrically valid; there was a positive relation between situationism and the use of situation‐control strategies; and situationism was higher for individuals from regions that are Eastern European and relatively more interdependent, compared with individuals from regions that are Western European and relatively less interdependent. As the first evaluation of the Situationism Scale outside America, this study supports the Scale's validity and suggests not only may some effects of situationism be universal, but between‐ and within‐culture differences in situationism exist. Overall, when making judgments and decisions about the self, cultural background and individual differences in situationism may come into play.     

Are Words Easier to Learn From Infant‐ Than Adult‐Directed Speech? A Quantitative Corpus‐Based Investigation

We investigate whether infant‐directed speech (IDS) could facilitate word form learning when compared to adult‐directed speech (ADS). To study this, we examine the distribution of word forms at two levels, acoustic and phonological, using a large database of spontaneous speech in Japanese. At the acoustic level we show that, as has been documented before for phonemes, the realizations of words are more variable and less discriminable in IDS than in ADS. At the phonological level, we find an effect in the opposite direction: The IDS lexicon contains more distinctive words (such as onomatopoeias) than the ADS counterpart. Combining the acoustic and phonological metrics together in a global discriminability score reveals that the bigger separation of lexical categories in the phonological space does not compensate for the opposite effect observed at the acoustic level. As a result, IDS word forms are still globally less discriminable than ADS word forms, even though the effect is numerically small. We discuss the implication of these findings for the view that the functional role of IDS is to improve language learnability.
