Stimulus repetition effects and the dimension-feature distinction in alternative targets

The negative repetition effect (NRE) refers to a poorer perception of the target in noise-same-as-target than in noise-alternative-target displays. Using the parenthesis as target and noise that are either identical or different in orientation, we tested predictions derived from a feature-specific inhibition model (Bjork & Murray, 1977) that explains the NRE as arising from inhibitory interactions among channels handling identical inputs. Contrary to our expectation of evidence for orientation-specific inhibition, a positive repetition effect (PRE) was observed. We also found a PRE for the dimension target sets whose stimuli differ only in orientation and an NRE for the feature target sets whose stimuli differ in the number of elements. Further experiments that systematically varied relationships between alternative targets indicate that these basic findings, termed the stimulus attributes effects, do not arise from pattern masking, perceptual strategies, or response bias.     

The time course of recognition of novel melodies

Seven experiments explored the time course of recognition of brief novel melodies. In a continuous-running-memory task, subjects recognized melodic transpositions following delays up to 2.0 min. The delays were either empty or filled with other melodies. Test items included exact transpositions (T), same-contour lures (SC) with altered pitch intervals, and different-contour lures (DC). DCs differed from Ts in the pattern of ups and downs of pitch. With this design, we assessed subjects’ discrimination of detailed changes in pitch intervals (T/SC discrimination) as well as their discrimination of contour changes (T/DC). We used both artificial and “real” melodies. Artificial melodies differed in conformity to a musical key, being tonal or atonal. After empty delays, T/DC discrimination was superior to T/SC discrimination. Surprisingly, after filled delays, T/SC discrimination was superior to T/DC. When only filled delays were tested, T/SC discrimination did not decline over the longest delays. T/DC performance declined more than did T/SC performance across both empty and filled delays. Tonality was an important factor only for T/SC discrimination after filled delays. T/DC performance was better with rhythmically intact folk melodies than with artificial isochronous melodies. Although T/SC performance improved over filled delays, it did not overtake T/DC performance. These results suggest that (1) contour and pitch-interval information make different contributions to recognition, with contour dominating performance after brief empty delays and pitch intervals dominating after longer filled delays; (2) a coherent tonality facilitates the encoding of pitch-interval patterns of melodies; and (3) the rich melodic—rhythmic contours of real melodies facilitate T/DC discrimination. These results are discussed in terms of automatic and controlled processing of melodic information.     

Aligning inside and outside perspectives of the self: A cross‐cultural difference in self‐perception

Past research shows that European Americans tend to take a first‐person perspective to understand the self and are unlikely to align the inside look with the outside gaze, whereas Asians tend to take a third‐person perspective and are likely to shift their inside look in the direction of the outsize gaze. In three experiments, we compared Asians and European Americans' self‐perceptions when the presence of their parents in the background of self‐perception was primed or otherwise. Without the priming, both European Americans and Asians viewed themselves more positively from their own perspective than from their parents' perspective. With the priming, only Asians lowered the positivity of their self‐perceptions to match the perceived positivity of the self in the parents' perspective. These results suggest that Asians do not have a static, passive tendency to assimilate their self‐views into the perceived external assessments of the self. Rather, their self‐views are fluid and flexible.     

Age and Gender Variations in Healthy Immigrant Effect: a Population Study of Immigrant Well-Being in Canada

The healthy immigrant effect (HIE) is the phenomenon in which immigrants show better health than their native-born counterparts but this healthier condition declines with length of residence. This study investigated whether (1) immigrants also show better adaptation than non-immigrants as well as better health, (2) length of residence affects their health and adaptation differently, and (3) differential outcomes are found for different age and gender groups. Utilizing the Canadian Community Health Survey (2011–2012) data, immigrants (N?=?17,555) and non-immigrants (N?=?103,579) were divided into adolescents (15–19 years old), adults (20–49), older adults (50–64), and seniors (65–74) to examine their subjective general and mental health, diagnosed chronic and psychological illnesses, and self-reported daily stress, life satisfaction and sense of belonging. After controlling for key demographics, HIE was found to be more robust in health than adaptation. In general, recent immigrants reported better health conditions than long-term immigrants; however, the two did not differ with daily stress or life satisfaction. The older adult immigrants were the only segment of the immigrant population who did not display HIE; within the immigrant population, working-aged long-term adult immigrants were those experiencing negative well-being in both health and adaptation compared to the same-aged recent immigrants. Regarding diagnosed psychological illnesses, immigrants yielded no difference by age, gender, or length of residence, indicating ‘reluctant’ views on seeking professional help for mental health were persistently held by both recent and long-immigrants. The findings suggest that health policy needs to take into consideration age-related life stages, and enhancement of mental health awareness for immigrant well-being.     

The Interplay of News Frames on Cognitive Complexity

This research considers how distinct news frames work in combination to influence information processing. It extends framing research grounded in prospect theory (Tversky & Kahneman, 1981) and attribution theory (Iyengar, 1991) to study conditional framing effects on associative memory. Using a 2 × 3 experimental design embedded within a probability survey (N= 379), tests examined the effects of two different frame dimensions—loss‐gain and individual‐societal—on the complexity of individuals' thoughts concerning the issue of urban growth. Findings indicate that news frames interact to generate more or less complex cognitive responses, with societal‐gain frame combinations generating the most detailed cognitions about the causes, components, and consequences of urban growth. Directions for research on media framing are discussed.     

Mobile Communication and Civil Society: Linking Patterns and Places of Use to Engagement with Others in Public

This study examined whether and how mobile communication influences the extent to which one engages with new people in public settings. Contrary to our expectation, general use of the technology in public did not detract from conversing with strangers. Shifting focus from where one uses the mobile phone to how it is used, we found that uses for coordination and news each lead to increased conversations with strangers in public settings, while relational use detracted from them. The findings also reveal an interactive effect such that those who use mobile technology for news and frequently use it in public were more likely to engage with strangers in public. The discussion offers interpretation of the findings and directions for future research.     

Korean dance performance influences on prospective tourist cultural products consumption and behaviour intention

We examined to what extent viewing the Korean dance performance by Beyond The Scene (BTS) at the 2018 Melon Music Awards influenced global viewers’ purchase of Korean cultural products and tourism behaviour intention. We surveyed 230 prospective tourists from the USA (black adult females = 50%; mean age = 34.9, SD = 1.116) in terms of their preference for Korean cultural products and intention to visit Korea. We conducted structural equation modelling to map the paths among cultural product preferences and tourism intentions. We found that viewing the Korean dance performance by BTS not only increased the purchase of Korean cultural products among participants, but also their tourism behaviour intention. We also found that the purchase of Korean cultural products by participants was associated with increased Korea tourism behaviour intention. We conclude from these data that viewing cultural performances by would-be tourists and their purchase preferences are important for promoting tourism through cultural industries.     

Corrigendum

Mild to moderate Parkinson's disease shows more denervation in the posterodorsal striatum and sparing of the anteroventral striatum. Dopaminergic medications can interfere with anteroventral striatum function by overdosing this relatively intact structure. The authors determined how regional striatal denervation affects medication-associated sequence learning impairment in Parkinson's disease. Eighteen Parkinson's patients performed motor sequence learning on and off levodopa. Patients underwent ¹¹C-dihydrotetrabenazine positron emission tomography scans to measure nigrostriatal denervation. Patients with more preserved putamen were more likely to exhibit levodopa-associated sequence learning impairments. Furthermore, the ratio of denervation in the anterior to posterior dorsal putamen predicted the level of learning differences on and off levodopa. These results demonstrate that the spatial pattern of nigrostriatal dopaminergic denervation predicts medication responsiveness for motor sequence learning.     

Uncertainty matters: impact of stimulus ambiguity on infant social referencing

Most infant social referencing studies have assumed that infants would be more likely to engage in social looking and be influenced by adults' message when a context is ambiguous. The present study empirically tested the effect of stimulus ambiguity on infants' referencing behaviours, with three different stimuli (positive, ambiguous, and negative), two different messages (happy and fearful), two different message providers (mother and stranger), and in two age groups (12 and 16 month olds). A typical social referencing paradigm was used and infants' social looking and regulation were measured. Infants looked at adults more frequently and faster during ambiguous situations than during unambiguous situations. They also tended to regulate their affect and behaviour based on adults' message only towards ambiguous toys. Older infants tended to look at adults faster, and showed stronger reactions towards ambiguous stimuli than younger infants, suggesting that infants' social development may moderate the effect of stimulus ambiguity on social referencing. Overall, results indicated that the ambiguity postulate is a legitimate assumption for infant social referencing. Copyright © 2010 John Wiley & Sons, Ltd.
