Voice and interpersonal attraction

The present study examined the effects of voice and physical appearance on inter-personal attraction. Furthermore, the attributes of voice that enhance interpersonal attraction were investigated. In the first study the subjects were 25 female students from one university and the target persons were four male students from another university. The subjects rated attractiveness of voice and physical appearance, and the overall interpersonal attraction of the target persons. The attractiveness of voice and physical appearance had independent effects on interpersonal attraction. In the second study the subjects were 62 students (20 males, 42 females) from one university and the target persons were 16 students from another university (eight of each sex). The results of the first study were replicated. Bright, generous voices, low vocal pitch and a small range of vocal pitch increased interpersonal attraction.     

Aphasic's comprehension of sentences expressing temporal order of events

Fifty-seven aphasic patients' comprehension of five sentence forms which express the temporal order of events has been investigated. Three major patterns of errors of temporal relations have emerged. The dominant pattern is exhibited by patients making errors on Before's but not on After's. The second and third patterns comprise a fewer number of patients making errors on After's but not on Before's and those making errors on both Before's and After's, respectively. It has been shown that different syndromes of aphasia are equally distributed among these three patterns. In the follow-up study of several patients, fluctuating courses of recovery in which comprehension of before and after alternately increases and decreases have been observed. These results are discussed in connection with a possible account of the acquisition of before and after in Japanese.     

Effects of laterality and pitch height of an auditory accessory stimulus on horizontal response selection: The Simon effect and the SMARC effect

In the present article, we investigated the effects of pitch height and the presented ear (laterality) of an auditory stimulus, irrelevant to the ongoing visual task, on horizontal response selection. Performance was better when the response and the stimulated ear spatially corresponded (Simon effect), and when the spatial—musical association of response codes (SMARC) correspondence was maintained—that is, right (left) response with a high-pitched (low-pitched) tone. These findings reveal an automatic activation of spatially and musically associated responses by task-irrelevant auditory accessory stimuli. Pitch height is strong enough to influence the horizontal responses despite modality differences with task target.     

A case report of compensation in daily life of a person with memory problems: detailed functional use of memory aids over a five-year period

Numerous studies have been conducted on memory aids for memory-impaired people. However, it is not known how they use these memory aids in a functional, practical way. A 20-year-old patient (MH) was monitored for five years to identify what memory aids or other means she used and how she used them to compensate for her memory problems, e.g., forgetting what was said by others in a few minutes and getting lost or turning in the wrong direction on a walk or in a building. Results indicated MH did not necessarily always use memory aids such as a notebook or calendar to compensate for her memory problems, although MH and her mother reported that she frequently used them in daily life. She coped with memory problems by using various "resources" besides the memory aid. These facts suggest that it may be necessary to redefine functionally useful compensations, which include both memory aids and resources in daily life.     

Are effects of emotion expression on trait impressions mediated by babyfaceness? Evidence from connectionist modeling

Two studies provided evidence that bolsters the Marsh, Adams, and Kleck hypothesis that the morphology of certain emotion expressions reflects an evolved adaptation to mimic babies or mature adults. Study 1 found differences in emotion expressions' resemblance to babies using objective indices of babyfaceness provided by connectionist models that are impervious to overlapping cultural stereotypes about babies and the emotions. Study 2 not only replicated parallels between impressions of certain emotions and babies versus adults but also showed that objective indices of babyfaceness partially mediated impressions of the emotion expressions. babyface effects were independent of strong effects of attractiveness, and babyfaceness did not mediate impressions of happy expressions, to which the evolutionary hypothesis would not apply.     

Semiquantitative analysis of surface relief due to martensite formation in Fe-Mn-Si-based shape memory alloys by atomic force microscopy

Semiquantitative analysis of the surface relief caused by martensite formation in Fe-Mn-Si-based shape memory alloys has been performed by atomic force microscopy. It is found, for the thermally induced martensite transformation, that all three possible variants of martensite with the same {111} habit plane appear while, for the stress-induced martensite transformation, only one martensite variant is likely to form. For the former case, martensite plates with various variants are formed on the same habit plane in such a way that the shape strains of those plates are self-accommodated macroscopically, but each martensite plate itself is a single variant and not a multivariant plate as has been reported in the literature. For the latter case, it is especially emphasized that all the martensite plates formed in the well 'trained' sample have the same variant, which is one of the most important conditions for exhibiting a good shape memory effect.     

Temporal characteristics of visual memory

In order to infer the temporal relations among iconic, short-term, and long-term components of visual memory, random dot patterns were used as memory stimuli in six recognition memory experiments. Experiment 1 demonstrated that recognition was still above chance for intervals up to 12 s. In Experiments 2 and 3, an intervening masking stimulus was found to be effective only if presented within the first 500 ms of the interval. The remaining three experiments employed a two-target task, with the second target replacing the masking stimulus. Recognition performance with the second target was the same as that in a single-target task, whereas performance with the first target was almost at chance level. Increasing the interval between the targets resulted in a gradual improvement in the recognition of the first target.     

Functional visual field in a rapid serial visual presentation task

Dynamic temporal change in the size of functional visual field was measured using a dual task: a peripheral task in which one square in a background pattern of squares was changed in shape to a dot; and a central task involving the rapid serial visual presentation of a sequence of letters (RSVP task). The temporal lag between the occurrences of the dot and the RSVP target was manipulated. University students were asked to detect the dot and to depress a mouse button as quickly as possible while searching for the RSVP target among a sequence of distracter letters. The abrupt change in the shape of a background square in the peripheral task caused a processing deficit in the RSVP task at relative lags from –3 to –1 (255 ms to 85 ms before presentation of the RSVP target), but the encoding and retaining processes involved in identifying the RSVP target did not impair the detection of the peripheral dot. The functional visual field was found to expand while participants were performing the dual task, suggesting that preattentive detection is affected by general attentional activity.     

Are olfactory images sensory in nature?

We investigated the features of olfactory mental images by comparing odour images with perceptual and semantic representations. Participants who were assigned to three groups made similarity judgments about 17 common odours by smelling odours, imagining odours, or on the basis of the meaning of odour source names. In the smelling group, every pair of odours was compared. In the imagining group, imagined odours were compared twice, both before and after associative learning of the odour/name combinations. In the meaning group, the odour source names were compared in terms of general word meanings. Nonmetric multidimensional scaling analysis was applied to each group of similarity data and three-dimensional sensory, mental, and semantic spaces were composed. 17 elements in the mental and semantic spaces were superimposed onto the sensory space by Procrustes rotation. We found that the averaged distances of the 17 elements between the sensory and the mental spaces (either before or after learning) were smaller than those between the sensory and semantic spaces. We suggest that odour images have sensory features, especially after associative learning between perceived odours and their names.     

Liar-type Paradoxes and the Incompleteness Phenomena

We define a liar-type paradox as a consistent proposition in propositional modal logic which is obtained by attaching boxes to several subformulas of an inconsistent proposition in classical propositional logic, and show several famous paradoxes are liar-type. Then we show that we can generate a liar-type paradox from any inconsistent proposition in classical propositional logic and that undecidable sentences in arithmetic can be obtained from the existence of a liar-type paradox. We extend these results to predicate logic and discuss Yablo’s Paradox in this framework. Furthermore, we define explicit and implicit self-reference in paradoxes in the incompleteness phenomena.
