Effectiveness of word order and grammatical marker as syntactic indicators of semantic relations

The effectiveness of word order and grammatical markers as syntactic indicators of semantic relations was explored using an artificial linguistic system. The results showed: (1) semantic interpretation of novel sentences was possible not only for Ss given fixed word order sentences with or without the markers, but also for Ss given the markers in random word order sentences; (2) Ss given neither indicator showed chance performance; (3) word order tended to be more efficient than grammatical markers as clues to semantic relations. The results suggest that the critical condition for language acquisition is the constant covariation of linguistic structure with semantic contexts. A process approach is discussed in accounting for the findings.Half of the data of the present experiment (FP and FA) were collected by Miss Norie Wake for her BA thesis, Okayama University (1978). The other half (RP and RA) were collected by the three juniors for their advanced course of experimental psychology, Okayama University (1979).     

Temporal course of activation of the antecedent by the reflexive in syntactically ambiguous sentences in Japanese

Three experiments examined the temporal course of the activation of an antecedent triggered by a reflexive,jibun, in syntactically ambiguous sentences in Japanese. Twenty-two students in Experiment 1 were tested for sentences where a subject word occupied the first position and an indirect object word the second, with the probe given for each word either immediately after the reflexive or at the end of the sentence. Reaction times (RTs) were faster when the probe was for subject (S-probe) than when it was for indirect object (IO-probe) irrespective of the probe position. Experiment 2 tested 22 students to determine the effect of order of mention of participant on the probe recognition time. RTs were faster for the S-probe than for the IO-probe, although the difference between the two probes was smaller when the probe was given immediately after the reflexive. Experiment 3 tested 22 students to examine the effect of context on an activation pattern. RTs were lower for the S-probe than for the IO-probe, though no difference was found between them for the probe given at the end of the sentence. Findings were interpreted as supporting the single-interpretation model for on-line analysis of syntactically ambiguous sentences and also the immediate-activation model in an assignment of the reflexive to its antecedent.     

Psychophysical isolation of the modality responsible for detecting multimodal stimuli: a chemosensory example

Multiple sense modalities can be stimulated conjointly by a physically complex item, such as a predator, and also by a physically solitary stimulus that acts on multiple receptor classes. As a prime example of this latter group, l-menthol from mint stimulates taste, smell, and several somatosensory submodalities. In 6 experiments that used a variety of psychometric techniques, the authors experimentally isolated the modality by which l-menthol is detected in the upper airways (the nose and mouth). Interestingly, absolute detection in both the nasal and oral cavities was based on olfaction and not stinging, cooling, or taste. These experiments illustrate how the sensory modality responsible for detecting a multimodal or multisensory stimulus can be psychophysically isolated.     

The Organization of Extrinsic Neurons and Their Implications in the Functional Roles of the Mushroom Bodies in Drosophila melanogaster Meigen

Although the importance of the Drosophila mushroom body in olfactory learning and memory has been stressed, virtually nothing is known about the brain regions to which it is connected. Using Golgi and GAL4–UAS techniques, we performed the first systematic attempt to reveal the anatomy of its extrinsic neurons. A novel presynaptic reporter construct, UAS-neuronal synaptobrevin–green fluorescent protein (n-syb–GFP), was used to reveal the direction of information in the GAL4-labeled neurons. Our results showed that the main target of the output neurons from the mushroom body lobes is the anterior part of the inferior medial, superior medial, and superior lateral protocerebrum. The lobes also receive afferents from these neuropils. The lack of major output projections directly to the deutocerebrum’s premotor pathways discourages the view that the role of the mushroom body may be that of an immediate modifier of behavior. Our data, as well as a critical evaluation of the literature, suggest that the mushroom body may not by itself be a “center” for learning and memory, but that it can equally be considered as a preprocessor of olfactory signals en route to “higher” protocerebral regions.     

Essentialist theory of ‘hybrids’: From animal kinds to ethnic categories and race

This article presents a theory of the perception of hybrids, resulting from cross‐breeding natural animals that pertain to different species and of children parented by couples with a mixed ethnic or racial background. The theory states that natural living beings, including humans, are perceived as possessing a deeply ingrained characteristic that is called ‘essence’ or ‘blood’ or ‘genes’ in everyday discourse and that uniquely determines their category membership. If, by whatever means, the genes or essences of two animals of different species are combined in a hybrid, the two incompatible essences collapse, leaving the hybrid in a state of non‐identity and non‐belonging. People despise this state and reject the hybrid (Study 1). This devaluation effect holds with cross‐kind hybrids and with hybrids that arise from genetically combining animals from incompatible habitats across three cultures: Austria, India and Japan (Study 2). In the social world, groups and ethnic or racial categories frequently are essentialized in an analogue way. When people with an essentialist mindset judge ethnically or racially mixed offspring, they perceive a collapse of ethnic or racial essence and, consequently, denigrate these children, as compared to children from ‘pure’ in‐group or out‐group parents (Study 3). The findings are discussed in terms of the widespread ‘yuck factor’ against genetically modified animals, in terms of the cultural concepts of monstrosity and of racism and prejudice.     

Biotechnology in the Japanese media: Comparative analysis of newspaper articles on genetic engineering in Japan and Europe

The present study examined how the representations of biotechnology using genetic engineering have been developed in Japan relying on media analysis. Specifically, using the online database of the Asahi Shimbun , one of the major opinion-forming newspapers in Japan, the annual numbers of articles concerning biotechnology were tallied from 1985 to 2000, and an analysis was conducted of the content of 850 articles from 10 particular years. Specifically, a framework in which a biotechnological issue was presented was focused on; the changes of dominant frames and the relationships between frames and specific biotechnological applications (e.g. medicine, agrifood and cloning) were investigated. The results showed that: (i) the number of articles increased sharply in particular since 1996–1997; (ii) although general attitudes toward biotechnology were persistently positive, a frame of biotechnological article became more diverse (i.e. the prospect frames were considerably dominant in the earlier phases, but the concern frames also became prominent in the later phases); and (iii) several articles were found which reported cloned animals in a frame of emotional attachment, a frame unique to Japan. These results were compared with those of European countries and discussed from a perspective of the theory of collective symbolic coping.     

Effectiveness of word order and grammatical markers as syntactic indicators of semantic relations in opaque input conditions

Using an artificial linguistic system an attempt was made: (1) to estimate the relative opacity between a meaning-form correspondence which would not interfere with the acquisition of a linguistic system and (2) to determine the relative effectiveness of word order and grammatical markers as syntactic indicators of semantic relations in less transparent input conditions. The results showed that syntax was induced even under 25% opaque conditions and that word order exhibited a slight tendency to be more effective than grammatical markers. Discussion emphasized the minimum amount of structural invariance necessary for a meaning-form mapping under opaque input conditions.     

Extraction of linguistically relevant referential properties through language learning

In order to identify the role of language in extracting a particular referential property which was involved in a reference situation but which was not expressed as relevant, in the linguistic structure of the subjects' native language, three experiments were performed. Forty subjects were exposed to the same referential situations but to different linguistic structures, each encoding a particular referential property that was, relevant. Miniature artificial languages were used. The referential properties examined were prototypical transitivity as defined by Slobin (1980) and plurality. The results showed that prototypical transitivity was extracted more readily than plurality, even though the subjects were more familiar with the latter property. The discussion emphasized how language serves to promote, the extraction and encoding of linguistically relevant properties that underlie referential situations.Deep gratitude is due to Prof. D. D. Steinberg for his cogent and critical reading of the earlier version of the paper.     

The structure of interpretations in family therapy: a video-enhanced exploration

A method for assessing the structure of interpretations of family therapy events is described. Family sessions were videotaped; each participant then independently reviewed the tape, stopping it to indicate any significant events and describing the importance of each identified sequence. Qualitative approaches to analyzing the stop points are described, using data from six families and their therapist. This combination of direct session experience and reflective interpretation provides a much-needed perspective on the meaning of sessions and psychotherapeutic interaction. Research and clinical implications for scientifically examining the structure of shared interpretations in family therapy are discussed.
