The value created by the removal of cut lines: Evaluating the impact of finishing of industrial designs on purchase intention

Color, material, and finish (CMF) are essential to the competitiveness of industrial products. However, in the existing research on CMF from the consumer behavior perspective, there is an insufficient focus on finish, compared with that on color and material. Research on finish is limited to technical methods, and there is a lack of discussion about its impact on consumer purchasing behavior. This study examines the effect of cars' exterior design finish on purchase intention in Japan. The research question is, “does changing the quality of the finish by removing cut lines have a positive effect on purchase intention?” Two sets of images were used: normal images of car exteriors and images of car exteriors improved by removing cut lines. An online survey was conducted to explore the impact of a car's finish on consumers' purchase intentions in the Japanese market. The randomized controlled trial results showed that finish had a significant positive effect on purchase intention. This study analyzes the interaction of finish with consumer characteristics. A multiple regression model with interactions revealed that, among consumers who emphasize design, a higher finish quality prompted a greater positive influence on purchase intention. In design research, styling tends to attract significant attention. However, practitioners should not neglect efforts to improve finishing when manufacturing products. Companies that consider it impossible to convey to consumers the quality of products with delicate finishing need to change their mindset. These suggestions apply not only to the automotive industry but also to other durable consumer goods industries.     

An fMRI study of temporal sequencing of motor regulation guided by an auditory cue—a comparison with visual guidance

The neuronal system to process and transfer auditory information to the higher motor areas was investigated using fMRI. Two different types of internal modulation of auditory pacing (1 Hz) were combined to design a 2×2 condition experiment, and the activation was compared with that under a visual guidance. The bilateral anterior portion of the BA22 (ant-BA22) and the left BA41/42 were more extensively activated by the combined modulation condition under the auditory cue than that under the visual cue. Among the four auditory conditions with or without the two types of internal modulation, the activation in the ant-BA22 was augmented only on the left side by the combined modulation condition. The left ant-BA22 may be especially involved in integrating the external auditory cue with internal modulation, while the activation on the right side did not depend on the complexity. The role of the left BA41/42 in motor regulation may be more specific to the processing of an auditory cue than that on the right side. These two areas in the left temporal lobe may be organized as a subsystem to handle the timing of complex movements under auditory cues, while the higher motor areas in the frontal lobe support both sensory modalities for the cue. This architecture may be considered as ‘audio-motor control’, which is similar to the visuo-motor control of the front-parietal network.     

Incidental learning of real-world regularities

The large literature on incidental learning relies almost exclusively on laboratory experiments. Whenever researchers have attempted to demonstrate incidental learning of real-world regularities, they have typically failed to show learning. For example, it is well established that people do not learn regularities in everyday objects, such as the left-right orientation of faces on coins, despite a very large exposure to them. In this report, we examine this apparent contradiction. We argue that most studies exploring real-life incidental learning use tests that are not as sensitive to low-confidence information as those traditionally used in laboratory tasks. Using more sensitive measures, we show that it is possible to learn regularities from British and Japanese cultural life as a direct result of exposure to these regularities. Further, confidence measures suggest that although the information may be acquired incidentally, it can be expressed with and without concomitant awareness of that knowledge.     

How young adults address their parents reflects their perception of parenting

A speaker's use of a title for the listener shows the speaker's deference to the listener. Previous studies suggested that the use of kinship terms in the family also shows deference to the listener. The present study focused on young adults' use of kinship terms for their parents to investigate whether their use of kinship terms reflects their perception of their parenting. The participants were 329 Japanese college students, who answered a questionnaire about their forms of address for their parents, perceived parental emotional accessibility, and perceived parental control. They also reported their satisfaction with their parent–child relationships and the frequency of parent–child communication. The results suggest that young adults who use kinship terms for their parents perceive their parents to be more emotionally accessible and communicate with their parents more than those who do not. Young adults who use kinship terms for their father are also more satisfied with their father–child relationships than those who do not. Young adults' use of kinship terms might signal not only their deference to their parents, but also their acceptance of their parent–child relationships.     

Chunking During Learning of Visuomotor Sequences with Spatial and Arbitrary Rules: Preliminary Findings

Visuomotor sequence learning requires participants to learn a two-fold process of learning the correct visuomotor transformation (spatial or arbitrary rules) and learning the correct order of performing the sequence. A motor sequence is performed with a specific timing pattern by grouping a number of elementary movements into chunks. The present research extends previous findings examining whether chunking phenomenon is observable for visuo-motor sequences with arbitrary transformations in addition to spatially defined targets. This research tests for dominant chunking patterns and individual variability.     

Individual identity and affective valence in marmoset calls: in vivo brain imaging with vocal sound playback

As with humans, vocal communication is an important social tool for nonhuman primates. Common marmosets (Callithrix jacchus) often produce whistle-like ‘phee’ calls when they are visually separated from conspecifics. The neural processes specific to phee call perception, however, are largely unknown, despite the possibility that these processes involve social information. Here, we examined behavioral and whole-brain mapping evidence regarding the detection of individual conspecific phee calls using an audio playback procedure. Phee calls evoked sound exploratory responses when the caller changed, indicating that marmosets can discriminate between caller identities. Positron emission tomography with [¹⁸F] fluorodeoxyglucose revealed that perception of phee calls from a single subject was associated with activity in the dorsolateral prefrontal, medial prefrontal, orbitofrontal cortices, and the amygdala. These findings suggest that these regions are implicated in cognitive and affective processing of salient social information. However, phee calls from multiple subjects induced brain activation in only some of these regions, such as the dorsolateral prefrontal cortex. We also found distinctive brain deactivation and functional connectivity associated with phee call perception depending on the caller change. According to changes in pupillary size, phee calls from a single subject induced a higher arousal level compared with those from multiple subjects. These results suggest that marmoset phee calls convey information about individual identity and affective valence depending on the consistency or variability of the caller. Based on the flexible perception of the call based on individual recognition, humans and marmosets may share some neural mechanisms underlying conspecific vocal perception.     

Evidence for model-based action planning in a sequential finger movement task

In this article, the authors examine whether and how humans use model-free, reflexive strategies and model-based, deliberative strategies in motor sequence learning. They asked subjects to perform the grid-sailing task, which required moving a cursor to different goal positions in a 5 × 5 grid using different key-mapping (KM) rules between 3 finger keys and 3 cursor movement directions. The task was performed under 3 conditions: Condition 1, new KM; Condition 2, new goal position with learned KM; and Condition 3, learned goal position with learned KM; with or without prestart delay time. The performance improvement with prestart delay was significantly larger under Condition 2. This result provides evidence that humans implement a model-based strategy for sequential action selection and learning by using previously learned internal model of state transition by actions.     

Educational level signals unobserved abilities of people with high functioning autism spectrum disorders

The effect of educational level on employment of people with high functioning autism spectrum disorders (HFASD) was examined. If education augments natural abilities to accomplish tasks in people with HFASD, then those with more education would have comparative advantages in both obtaining and retaining jobs. In contrast, if education did not augment natural abilities and only signaled unobservable abilities, one would expect an advantage only in obtaining a job, but not in retention. 22 people with HFASD replied to questionnaires regarding their history of education and employment. Those with job experience had higher educational levels than those with no job experience, but educational level was not significantly different between groups with and without more than one year of job experience. Educational level seems to be associated with abilities, but probably the unobserved abilities underlie both educational attainment and employment history.     

The Relationship Between Academic Oral Proficiency and Reading Performance: A Comparative Study Between English Learners and English-Only Students

This study investigates the relationship between oral proficiency and reading proficiency in English-learning children (L2 students) and native English-speaking children (NE students). A set of oral activities measuring students’ academic oral skills in science classes was developed and administered to 61 fourth graders. Both the meaning-related aspects and the formal aspects of the students’ academic oral proficiency were compared between strong and struggling readers and between NE and L2 students. The study thus used a 2 × 2 factorial design (Strong/Struggling Readers × NE/L2 Students). After controlling for the students’ nonverbal analytic and reasoning skills, this study found that strong and struggling readers showed different levels of performance with respect to the meaning-related aspects of oral academic language but not with respect to the formal aspects of language. Conversely, differences between NE and L2 students were found in components related to the formal aspects but not in those related to the meaning aspects of oral language.
