Orthographic Knowledge Important in Comprehending Elementary Chinese Text by Users of Alphasyllabaries

Orthographic knowledge in Chinese was hypothesized to affect elementary Chinese text comprehension (four essays) by 80 twelve-year-old ethnic alphasyllabary language users compared with 74 native Chinese speakers at similar reading level. This was tested with two rapid automatized naming tasks; two working memory tasks; three orthographic knowledge tasks in Chinese; and equivalent tasks in English. Multivariate analyses of covariance showed that the two groups were differentiated on most of the linguistic and cognitive tasks. Confirmatory factor analyses found four factors as hypothesized: text comprehension, verbal working memory, orthographic knowledge in Chinese, and orthographic knowledge in English. Hierarchical multiple regression analyses showed that orthographic knowledge in Chinese explained a considerable amount of individual variation in elementary Chinese text comprehension.     

Emotion Dysregulation and Affective Intensity Mediate the Relationship Between Childhood Abuse and Suicide‐Related Behaviors Among Women with Bulimia Nervosa

Self‐harm and suicide attempts occur at elevated rates among individuals with bulimia nervosa, particularly among those who have experienced childhood abuse. This study investigated the potential mediating roles of emotion dysregulation and affective intensity in the relationship between these variables in 125 women with bulimia nervosa. Analyses revealed that emotion dysregulation mediated the relationship between sexual and emotional abuse with both self‐harm and suicide attempts. Negative affective intensity mediated the relationship between abuse and suicide attempts. The findings may advance the understanding of mechanisms underlying suicide‐related behaviors in women with bulimia nervosa who experienced abuse and suggest potential clinical targets.     

Semantic inhibition of ignored words during a figure classification task

Two experiments investigated inhibitory processes in visual spatial attention. In particular, factors influencing the suppression of ignored visual stimuli were investigated. Subjects responded to geometric shapes while distractors were presented in the periphery. Distractors consisted of a single word, a pair of unrelated words, or a single word paired with a string of non-linguistic symbols. Semantic processing of the ignored words was measured with a subsequent lexical decision task. Test probes presented after the prime displays revealed suppression effects for words semantically related to a previously ignored word, but only for conditions in which two distractor words were presented. Suppression was not observed when the prime consisted of a single word or a single word paired with non-linguistic symbols. In Experiment 2 two different time delays between the onset of the primes and the onset of the test probes were used. At the shorter interval facilitatory priming was observed, while at longer intervals suppression was observed. The facilitation-suppression pattern suggests that ignored items are recognized before being suppressed. In summary, the results suggest the following: (1) that selectively attending does not restrict ignored items from gaining access to their semantic representations, and (2) that inhibition is an important process in determining the focus of attention. These results are discussed within a selective attention framework in which all items in a display gain access to memory representations, and attention to selected items causes competing items to be inhibited.
