Playing it by ear: gregarious sparrows recognize and respond to isolated wingbeat sounds and predator-based cues

Animal Cognition - The ability to detect an incoming attack provides a final opportunity for an animal to avoid predation. In birds, vision is the main sensory mode in detecting attacks, but...     

Mandarin speech perception by ear and eye follows a universal principle

In this study, the nature of speech perception of native Mandarin Chinese was compared with that of American English speakers, using synthetic visual and auditory continua (from /ba/ to /da/) in an expanded factorial design. In Experiment 1, speakers identified synthetic unimodal and bimodal speech syllables as either /ba/ or /da/. In Experiment 2, Mandarin speakers were given nine possible response alternatives. Syllable identification was influenced by both visual and auditory sources of information for both Mandarin and English speakers. Performance was better described by the fuzzy logical model of perception than by an auditory dominance model or a weighted-averaging model. Overall, the results are consistent with the idea that although there may be differences in information (which reflect differences in phonemic repertoires, phonetic realizations of the syllables, and the phonotactic constraints of languages), the underlying nature of audiovisual speech processing is similar across languages.     

Development of infant ear asymmetries for speech and music

Groups of 2-, 3-, and 4-month olds were tested for dichotic ear differences in memory-based phonetic and music timbre discriminations. A right-ear advantage for speech and a left-ear advantage (LEA) for music were found in the 3- and 4-month-olds. However, the 2-month-olds showed only the music LEA, with no reliable evidence of memory-based speech discrimination by either hemisphere. Thus, the responses of all groups to speech contrasts were different from those to music contrasts, but the pattern of the response dichotomy in the youngest group deviated from that found in the older infants. It is suggested that the quality or use of lefthemisphere phonetic memory may change between 2 and 3 months, and that the engagement of right-hemisphere specialized memory for musical timbre may precede that for left-hemisphere phonetic memory. Several directions for future research are suggested to determine whether infant short-term memory asymmetries for speech and music are attributable to acoustic factors, to different modes or strategies in perception, or to structural and dynamic properties of natural sound sources.     

Speaking to the trained ear: musical expertise enhances the recognition of emotions in speech prosody

Language and music are closely related in our minds. Does musical expertise enhance the recognition of emotions in speech prosody? Forty highly trained musicians were compared with 40 musically untrained adults (controls) in the recognition of emotional prosody. For purposes of generalization, the participants were from two age groups, young (18-30 years) and middle adulthood (40-60 years). They were presented with short sentences expressing six emotions-anger, disgust, fear, happiness, sadness, surprise-and neutrality, by prosody alone. In each trial, they performed a forced-choice identification of the expressed emotion (reaction times, RTs, were collected) and an intensity judgment. General intelligence, cognitive control, and personality traits were also assessed. A robust effect of expertise was found: musicians were more accurate than controls, similarly across emotions and age groups. This effect cannot be attributed to socioeducational background, general cognitive or personality characteristics, because these did not differ between musicians and controls; perceived intensity and RTs were also similar in both groups. Furthermore, basic acoustic properties of the stimuli like fundamental frequency and duration were predictive of the participants' responses, and musicians and controls were similarly efficient in using them. Musical expertise was thus associated with cross-domain benefits to emotional prosody. These results indicate that emotional processing in music and in language engages shared resources.     

Playing it cool: Temperament, emotion regulation, and social behavior in preschoolers

The contributions of temperamental styles and emotional coping strategies to the development of preschoolers' social competence and behavior problems were investigated. The ability to cope with emotion was found to be more important than temperament alone in the development of prosocial behavior. Our results indicate that the use of passive coping strategies may play a significant role in the development of maladaptive behaviors in young children. Specifically, the use of passive coping strategies was found to moderate the relationship between temperament dimensions in predicting externalizing and internalizing maladaptive behaviors. When combined with extremely negative temperamental dispositions, just facing the problems was discovered to be beneficial for preschoolers, which encourages the use of preventative or interventional strategies in the classroom to develop constructive emotion regulation skills in young children.     

Monaural ear differences for same-different reaction times to speech with prior knowledge of ear stimulated.

Morais and Darwin's (1974) finding of a right-ear advantage for speech on a "same-different" reaction-time task under monaural stimulation was replicated with 8 Ss who knew before each block of trials which ear would be stimulated. The effect cannot be accounted for in terms of a lateral bias in voluntary attention.     

Investigation of phonological encoding through speech error analyses: achievements, limitations, and alternatives.

Phonological encoding in language production can be defined as a set of processes generating utterance forms on the basis of semantic and syntactic information. Most evidence about these processes stems from analyses of sound errors. In section 1 of this paper, certain important results of these analyses are reviewed. Two prominent models of phonological encoding, which are mainly based on speech error evidence, are discussed in section 2. In section 3, limitations of speech error analyses are discussed, and it is argued that detailed and comprehensive models of phonological encoding cannot be derived solely on the basis of error analyses. As is argued in section 4, a new research strategy is required. Instead of using the properties of errors to draw inferences about the generation of correct word forms, future research should directly investigate the normal process of phonological encoding.     

The long and short of it: Reports of pause occurrence and duration in speech

Native speakers of American English and of German listened to a passage several minutes in duration in each language and reported occurrence and duration of pauses. Subjects overestimated occurrence (false positives) and understimated duration. Overall analyses of variance indicated that Germans reported a higher percentage of pauses than Americans; that a higher percentage of pauses was reported in native than in nonnative passages; that Americans reported a higher percentage of pauses in English passages, whereas Germans' percentages were the same in both languages; that American women reported more false positives than American men, whereas German men reported more than German women; and that Americans and Germans both reported more false positives in English than in German. Detailed analyses of the individual passages yielded reliable differences between Germans and Americans in their reports of pauses in three duration brackets: .3;,<1.0;1.0 sec. Pause reports of this kind diverge from objectively measured pause data as a function of a number of independent variables and are therefore not to be trusted as objective estimates of either pause occurrence or pause duration.     

It's the way that you, er, say it: hesitations in speech affect language comprehension

Everyday speech is littered with disfluency, often correlated with the production of less predictable words (e.g., Beattie & Butterworth [Beattie, G., & Butterworth, B. (1979). Contextual probability and word frequency as determinants of pauses in spontaneous speech. Language and Speech, 22, 201-211.]). But what are the effects of disfluency on listeners? In an ERP experiment which compared fluent to disfluent utterances, we established an N400 effect for unpredictable compared to predictable words. This effect, reflecting the difference in ease of integrating words into their contexts, was reduced in cases where the target words were preceded by a hesitation marked by the word er. Moreover, a subsequent recognition memory test showed that words preceded by disfluency were more likely to be remembered. The study demonstrates that hesitation affects the way in which listeners process spoken language, and that these changes are associated with longer-term consequences for the representation of the message.     

Fighting self-control failure: Overcoming ego depletion by increasing self-awareness

According to the limited strength model (Muraven, Tice & Baumeister, 1998), exerting self-control causes ego depletion: a depletion of cognitive resources resulting in poorer performance on later self-control tasks. Previous studies have demonstrated a positive effect of self-awareness on self-control performance. The present study examined whether the occurrence of ego depletion can be circumvented by increasing self-awareness. Initially depleted participants who received a neutral prime exhibited the classic ego depletion pattern: their performance on a subsequent physical self-control task decreased significantly. In contrast, no decrease in performance was observed for depleted participants who were exposed to a self-awareness prime. The latter group performed equally well compared to low depleted participants.     

The Aesthetic Preference: Overcoming the Pragmatic Error

Family therapists share the belief that people simultaneously are parts of a multiplicity of contexts, one of which is the family. The family contexts connect people in patterns as part of the unity of all contexts. Family systems, like all other living systems in nature are structured entities governed by such aesthetic principles as symbolic representation, order, patterning, balance, and unity. Our therapeutic techniques have been created to help transform the various patterns of connections within families, our goal being to help increase the degree of personal and interpersonal flexibility and differentiation for each part of the family system. The family therapist is like the artist searching for a beauty and unity of structure. It is through that aesthetic process that flexibility and differentiation are best furthered. Discovering the nature of the meaningful aesthetic arrangements within family systems is the difference that makes a difference in defining ourselves as family therapists. That difference involves us as part of a paradigmatic movement ( 4 , 20 ) espousing an ecological systems epistemology of mental life.     

Staring at the Sun: Overcoming the Terror of Death

In this article, the author, an eminent psychiatrist, psychotherapist, and writer, presents a brief introduction to the problem of human mortality as one of the givens of human existence, locating the problem squarely in the domain of self- awareness or human consciousness. He names the problem as death anxiety, a fear that can erupt into terror depriving an individual of happiness and fulfillment. Having identified the problem of death anxiety, the author then goes on, through a personal memoir, to disclose his personal ideas about death, their autobiographical sources, and how they have affected his life, as well as his coming to terms with the necessity of his own death. Within this autobiographical essay, he touches on experiences of death and dying from his youth, adolescence, and adulthood as well as his experience of the death of three of his most prized mentors: Jerome Frank, John Whitehorn, and Rollo May.     

What you say and how you say it: the contribution of speech content and voice quality to judgments of others

In three studies, judgments based on separated channels (speech content, voice quality, face alone and body alone) were correlated with judgments based on combined channels (speech, face + speech, and face + body + speech). The judges observed spontaneous behavior in two different types of interview situations and rated various aspects of the behavior. Correlations between separated and combined channels varied significantly depending on the kind of behavior judged, the attribute rated, and whether other channels of information were available.     

Getting it right by getting it wrong: When learners change languages

When natural language input contains grammatical forms that are used probabilistically and inconsistently, learners will sometimes reproduce the inconsistencies; but sometimes they will instead regularize the use of these forms, introducing consistency in the language that was not present in the input. In this paper we ask what produces such regularization. We conducted three artificial language experiments, varying the use of determiners in the types of inconsistency with which they are used, and also comparing adult and child learners. In Experiment 1 we presented adult learners with scattered inconsistency - the use of multiple determiners varying in frequency in the same context - and found that adults will reproduce these inconsistencies at low levels of scatter, but at very high levels of scatter will regularize the determiner system, producing the most frequent determiner form almost all the time. In Experiment 2 we showed that this is not merely the result of frequency: when determiners are used with low frequencies but in consistent contexts, adults will learn all of the determiners veridically. In Experiment 3 we compared adult and child learners, finding that children will almost always regularize inconsistent forms, whereas adult learners will only regularize the most complex inconsistencies. Taken together, these results suggest that regularization processes in natural language learning, such as those seen in the acquisition of language from non-native speakers or in the formation of young languages, may depend crucially on the nature of language learning by young children.     

Overcoming the Shame of Cancer

The author describes the silencing and dehumanizing effects of being diagnosed with cancer. This experience evolved from a sense of being totally stunned, to being flooded with shame, and finally to be able to reenter an experience of subjectivity through the support of his family, friends, and community. He describes his personal struggle to disclose having cancer to his patients and supervises and the incredible beneficial effects of disclosure and being virtually and actually held and cared for. The author describes from Relational, Kleinian, and Lacanian perspectives his understanding of the effects of self-disclosure in reestablishing the capacity for symbolization and the ability to create personal meaning.     

Overcoming the myth of the mental

Can we accept John McDowell’s Kantian claim that perception is conceptual “all the way out,” thereby denying the more basic perceptual capacities we seem to share with prelinguistic infants and higher animals? More generally, can philosophers successfully describe the conceptual upper floors of the edifice of knowledge while ignoring the embodied coping going on on the ground floor? I argue that we shouldn’t leave the conceptual component of our lives hanging in midair and suggest how philosophers who want to understand knowledge and action can profit from a phenomenological analysis of the nonconceptual embodied coping skills we share with animals and infants, as well as the nonconceptual immediate intuitive understanding exhibited by experts.
