Problems with popper: The initial goal is to develop viable theories, not disconfirm them

This paper examines the relation between errors and awareness in two recent theories of error detection in speech: Perceptual Loop theory and Node Structure theory. New data and predictions are discussed, together with some nonobvious limitations of these theories. New paradigms for studying speech error detection are also discussed, together with implications for current theories of the large body of work on error detection in related skills such as reading, typing, and handwriting.     

Clowning—An opportunity for ministry

Experiences over five years interacting with patients as the clown Jingles and the experiment and experience of one afternoon as the clown Hairie in a hospital led the authors to reflect on the deeper meaning of clowns, their appearance during the centuries, their impact on people and relation to ministry. The presence of a clown changes the atmosphere and dynamics; clowns touch people in their deep feelings and may free them to laugh, to cry, or to play. Relating to others in lively ways brings up questions about the connections between the clown and God.     

Cross-language facilitation,semantic blindness,and the relation between language and memory: A reply to Altarriba and Soltano

This comment corrects some inaccuracies, points to some methodological problems, and makes three substantive observations regarding the Altarriba and Soltano (1996) article. First, token individuation theory does not explain what is new and interesting in the Altarriba and Soltano data, namely cross-language semantic facilitation in lists and a list-sentence effect, that is, a large difference in the effect of semantic repetition when identical translation equivalents occurred in sentences versus lists. Second, Altarriba and Soltano’s small and nonsignificant semantic blindness effect for translation equivalents in split-language sentences is attributable to the peculiar nature of their materials, procedures, analyses, and experimental design. These problems nullify their conclusion that semantic blindness does not occur, and we discuss several clear cases where semantic blindness has been demonstrated. Finally, we suggest an explanation for Altarriba and Soltano’s unexplained effects (cross-language facilitation and the list-sentence effect) and show why these effects are important for the general issue of relations between language and memory.     

REPETITION BLINDNESS INTERACTS WITH SYNTACTIC GROUPING IN RAPIDLY PRESENTED SENTENCES

Abstract— This study rested for predicted effects of syntax on a repetition deficit (RD) known as repetition blindness, the reduced probability of recall for repeated words in rapid serial visual presentation (RSVP) sentences The syntactic variable was phrase-congruent versus phrase-incongruent grouping within simultaneous RSVP displays With phrase-congruent grouping, each RSVP display contained a syntactic phrase (e g, "to play sports" in the sentence "They wanted to play sports but sports were not allowed"), whereas with phrase-incongruent grouping, RSVP displays contained nonphrases (e g, "sports but sports") RD was extensive with phrase-incongruent grouping (29%), but nonsignificant (6%) with phrase-congruent grouping, as if phrase-congruent groups free up the extra processing time needed to connect repeated words into phrases in rapidly presented sentences, enabling top-down retrieval of the phrases during recall The present results comport with effects of syntax and prosody on auditory RD, and suggest that visual and auditory RD are identical underlying phenomena.     

Infant crying: Acoustics,perception and communication

This paper first reviews briefly the literature on the acoustics of infant cry sounds and then presents two empirical studies on the perception of cry and noncry sounds in their social-communicative context. Acoustic analysis of cry sounds has undergone dramatic changes in the last 35 years, including the introduction of more than a hundred different acoustic measures. The study of cry acoustics, however, remains largely focused on neonates who have various medical problems or are at risk for developmental delays. Relatively little is known about how cry sounds and cry perception change developmentally, or about how they compare with noncry sounds. The data presented here support the notion that both auditory and visual information are important in caregivers' interpretations of infant sounds in naturalistic contexts. When only auditory information is available (Study 1), cry sounds become generally more recognizable from 3 to 12 months of age; perception of noncry sounds, however, generally does not change over age. When auditory and visual information contradict each other (Study 2), adults tend to perform at chance levels, with a few interesting exceptions. It is suggested that broadening studies of acoustic analysis and perception to include both cry and noncry sounds should increase our understanding of the development of communication in infancy. Finally, we suggest that examining the cry in its developmental context holds great possibility for delineating the factors that underlie adults' responses to crying.     

A functional assessment of heterosocial initiation behaviors in adults

The present investigation was designed to assess the relationship between empirically defined behavioral strategies and ratings of social effectiveness, liking, and skill. Female subjects rated audiotapes of dyadic heterosocial interactions. The dyads' verbal behavior was manipulated experimentally such that each male actor exhibited one of two strategies, other-enhancement and positive self-presentation, and each female coactor exhibited one of two responses, encourages and discourages. After each audiotaped interaction, subjects rated each male on five questions: liking, continued interaction, effectiveness, social skill, and similarity. The results indicated that subjects distinguished between effective and ineffective strategies. The data obtained from all questions indicated that subjects preferred the male who was encouraged irrespective of what strategy he used. This study analyzed relevant variables within an interactional framework allowing for a functional, rather than topographic, analysis of social behavior. From this functional perspective, topographically different heterosocial initiation strategies may be viewed as appropriate or effective based on the reactions of the other person in the interaction.     

Probabilistic multidimensional scaling: Complete and incomplete data

Simple procedures are described for obtaining maximum likelihood estimates of the location and uncertainty parameters of the Hefner model. This model is a probabilistic, multidimensional scaling model, which assigns a multivariate normal distribution to each stimulus point. It is shown that for such a model, standard nonmetric and metric algorithms are not appropriate. A procedure is also described for constructing incomplete data sets, by taking into consideration the degree of familiarity the subject has for each stimulus. Maximum likelihood estimates are developed both for complete and incomplete data sets. This research was supported by National Science Grant No. SOC76-20517. The first author would especially like to express his gratitude to the Netherlands Institute for Advanced Study for its very substantial help with this research.
