Studies on iconic memory demonstrate that rich information from a visual scene quickly becomes unavailable with the passage of time. The decay rate of iconic memory refers to the dynamics of memory availability. The present study investigated the iconic memory decay of different stimulus attributes that comprised an object. Specifically, in Experiment 1, participants were presented with eight coloured numbers (e.g., red 4) and required to remember only one attribute, either colour or number, over different blocks of trials. The participants then reported the cued attribute in which the cue Stimulus Onset Asynchrony (SOA) from the memory array onset was varied (0, 100, 200, 300, 500, and 1000?ms). We found that numerical information became unavailable more quickly than colour information, despite the fact that the memory accuracies at 0 and 1000?ms SOAs were comparable between the two attributes. In Experiment 2, we replicated the finding that a numerical representation was lost more quickly than a colour representation when visual masks followed the target stimulus. These results suggest that the various visual attributes comprising an object are lost over time at different rates in iconic memory. We discuss this finding in relation to how perceptual representation is transferred to the capacity-limited visual working memory. 相似文献
Although considerable research has been conducted on consumer attitude towards foreign products, most of these studies focus on the attitude of products from Western developed countries. Our study intends to investigate the effects of consumers' national identification and culture sensitivity on their perceived risk of buying products from Eastern developing countries. Especially, this study advances the literature by identifying the mediation effect of consumer ethnocentrism and the moderating effect of consumer value consciousness. Taking China and India as focal emerging economies, the consumer survey (n = 308) in the United Kingdom produced the following results. First, U.K. consumers' national identification is positively related to their perceived risk of buying Eastern products through consumer ethnocentrism, whereas their cultural sensitivity has a negative relationship. Second, the effect of consumer ethnocentrism on the perceived risk of buying Eastern products is moderated by consumer value consciousness. Third, value consciousness also attenuates the indirect relationships between national identification or cultural sensitivity and perceived risk via consumer ethnocentrism. 相似文献
Although the value of relational benefits has been recognised in customer relationship management, the impact of these benefits on loyalty behaviours is yet to be investigated in the context of loyalty clubs. Little is known why some loyalty programmes outperform others. By using both qualitative and quantitative research approaches, this research developed and estimated a conceptual model that describes the interaction of key relational benefits and their contributions to customer loyalty in a set of milk formula customer clubs in China. Data were collected from 300 Chinese infant milk formula buyers, including both customer club members and nonmembers. This study confirms that the customer‐confidence benefits and identity‐related benefits precede other loyalty rewards and strengthen other loyalty incentives in a loyalty programme. The economic benefits and information‐sharing benefits play a mediating role and contribute directly to customer loyalty. The findings of this research help better understand the mechanism behind loyalty behaviours in customer clubs. 相似文献
This study investigated relations among children's Theory‐of‐Mind (ToM) development, early sibling interactions, and parental discipline strategies during the transition to siblinghood. Using a sample of firstborn children and their parents (N = 208), we assessed children's ToM before the birth of a sibling and 12 months after the birth, and sibling interactions (i.e., positive engagement and antagonism) and parental discipline strategies (i.e., child‐centred and parent‐centred discipline) at 4 and 8 months in the first year of siblinghood. Structural equation modelling analyses revealed that children's ToM before the birth of the sibling predicted children's positive engagement with the infant sibling, whereas children's antagonistic behaviours towards the infant sibling negatively predicted children's ToM at 12 months, but only when mothers used low levels of child‐centred discipline. These findings emphasize the role of parents in the development of young children's social‐cognitive understanding in the context of early sibling interactions.
Highlights
This study investigated relations among firstborns' Theory‐of‐Mind (ToM), early sibling relationships, and parental discipline during the first year of siblinghood.
Multigroup analyses showed that ToM predicted higher sibling positive engagement, and early sibling antagonism predicted poorer ToM when mothers used low child‐centred discipline.
Parental discipline plays an important role in the development of young children's social understanding and sibling relationships as early as the first year of siblinghood.
The orienting of attention has been found to be influenced by the previous cueing status in a spatial-cueing paradigm. The explanation for this sequence effect remains uncertain. This study separated the involuntary and the voluntary components of arrow cueing by manipulating the predicted target locations. For example, a left arrow cue may have indicated that the target was more likely to appear at the up location. Therefore, three trial types were repeated or switched between trials: cued (targets appeared along the direction of the arrows), predicted (targets appeared at the locations predicted by the arrows), and unrelated (targets appeared at the other two locations, neither cued nor predicted). RTs of cued trials were found to be significantly facilitated after a previous cued trial; however, the same effect was not observed for predicted trials. The results suggest that significant sequence effects are induced only in the involuntary component of arrow cueing. The findings support the feature-integration hypothesis for the sequence effect of symbolic cueing.
We assessed the vocational personality of 104 graduate students in school counseling, mental health counseling, and school psychology programs using Holland's ( 1997 ) theory of personality and career choice. The correlational findings confirmed the importance of vocational personality traits in relation to the academic performance of graduate students. Among the Self‐Directed Search–Revised vocational personality types, the Investigative type emerged as a consistent predictor of performance on all sections of the Graduate Record Examination. The participants from 3 graduate programs predominantly identified Social as their primary vocational personality type, with variability in the secondary and tertiary code positions. The student group with the highest degree of congruence, defined as the degree of fit between one's personality and the environment, had the highest graduate grade point average, indicating the relationship between the degree of congruence and achievement. Theoretical and practical implications of the findings are discussed. 相似文献
This study investigated explicit knowledge of autobiographical memory functions using a newly developed questionnaire. European and Asian American adults (N = 57) and school-aged children (N = 68) indicated their agreement with 13 statements about why people think about and share memories pertaining to four broad functions—self, social, directive and emotion regulation. Children were interviewed for personal memories concurrently with the memory function knowledge assessment and again 3 months later. It was found that adults agreed to the self, social and directive purposes of memory to a greater extent than did children, whereas European American children agreed to the emotion regulation purposes of memory to a greater extent than did European American adults. Furthermore, European American children endorsed more self and emotion regulation functions than did Asian American children, whereas Asian American adults endorsed more directive functions than did European American adults. Children's endorsement of memory functions, particularly social functions, was associated with more detailed and personally meaningful memories. These findings are informative for the understanding of developmental and cultural influences on memory function knowledge and of the relation of such knowledge to autobiographical memory development. 相似文献
In this 8‐year longitudinal study, we traced the vocabulary growth of Chinese children, explored potential precursors of vocabulary knowledge, and investigated how vocabulary growth predicted future reading skills. Two hundred and sixty‐four (264) native Chinese children from Beijing were measured on a variety of reading and language tasks over 8 years. Between the ages of 4 to 10 years, they were administered tasks of vocabulary and related cognitive skills. At age 11, comprehensive reading skills, including character recognition, reading fluency, and reading comprehension were examined. Individual differences in vocabulary developmental profiles were estimated using the intercept‐slope cluster method. Vocabulary development was then examined in relation to later reading outcomes. Three subgroups of lexical growth were classified, namely high‐high (with a large initial vocabulary size and a fast growth rate), low‐high (with a small initial vocabulary size and a fast growth rate) and low‐low (with a small initial vocabulary size and a slow growth rate) groups. Low‐high and low‐low groups were distinguishable mostly through phonological skills, morphological skills and other reading‐related cognitive skills. Childhood vocabulary development (using intercept and slope) explained subsequent reading skills. Findings suggest that language‐related and reading‐related cognitive skills differ among groups with different developmental trajectories of vocabulary, and the initial size and growth rate of vocabulary may be two predictors for later reading development. 相似文献
