Developmental changes in the linguistic performance correlates of reading achievement

The present study evaluated the hypothesis that measures of linguistic skills differentially contribute to the variability in reading achievement at different ages. Linguistic skills that develop earlier and are more important for earlier phases of reading were predicted to contribute more to the variability of reading achievement at earlier ages (5–7) than at older ages (10–12). Conversely, linguistic skills that develop later and are more important for later phases of reading were predicted to contribute more to the variability in reading achievement at older ages (10–12) than at younger ages (5–7). To test these developmental hypotheses, measures of language skills with different developmental rates were administered to cross-sectional samples of disabled and nondisabled readers at three mean ages: 5.5, 8.5, and 11 years. Reading group differences were apparent at each age on measures assumed to develop earlier, thus failing to confirm the first prediction. However, these measures may not have been sensitive to linguistic skills important for beginning reading. Reading group differences on measures of later developing language skills were apparent only for older readers, thus confirming the second prediction. The latter age-dependent relationships provided additional evidence for developmental changes in the linguistic correlates of reading achievement.     

Selective interference with image retention and generation: Evidence for the workspace model

We address three types of model of the relationship between working memory (WM) and long-term memory (LTM): (a) the gateway model, in which WM acts as a gateway between perceptual input and LTM; (b) the unitary model, in which WM is seen as the currently activated areas of LTM; and (c) the workspace model, in which perceptual input activates LTM, and WM acts as a separate workspace for processing and temporary retention of these activated traces. Predictions of these models were tested, focusing on visuospatial working memory and using dual-task methodology to combine two main tasks (visual short-term retention and image generation) with two interference tasks (irrelevant pictures and spatial tapping). The pictures selectively disrupted performance on the generation task, whereas the tapping selectively interfered with the retention task. Results are consistent with the predictions of the workspace model.     

An attachment perspective on human-pet relationships: Conceptualization and assessment of pet attachment orientations

In a series of studies we used attachment theory as a framework to examine human-pet relationships. We proposed that, as in interpersonal relationships, people differ in their degree of anxious or avoidant attachment to their pets, and that these individual differences influence pet-related cognitions, emotions, and behavior. We constructed a self-report scale, the Pet Attachment Questionnaire (PAQ), and examined its factorial structure, associations with attachment patterns in human relationships (Studies 1-2), relation to explicit and implicit expectations concerning a pet (3-4), and reactions to the loss of a pet (5). We found that individual differences in pet attachment do occur in the domains of attachment anxiety and avoidance, and these differences contribute uniquely to the prediction of expectations about the pet and emotional reactions to its death.     

情绪劳动与心理健康的关系:工作倦怠的中介作用

主要探讨情绪劳动与心理健康的关系以及工作倦怠对二者关系的中介作用。采用情绪劳动量表、心理健康量表和工作倦怠量表对山东省5家医院的200名护士进行问卷调查。结果表明,情绪劳动与心理健康呈显著负相关,对心理健康具有显著的负向预测作用,具体表现为对躯体化、焦虑、妄想和精神病性有负向预测作用;情绪劳动与工作倦怠呈显著正相关,对工作倦怠具有显著的正向预测作用,表现在情绪衰竭和去人格化两个方面。工作倦怠是情绪劳动与心理健康关系的中介变量,工作倦怠对情绪劳动与心理健康之间的关系具有完全中介作用,情绪劳动通过工作倦怠间接影响心理健康。     

Categorizing identity from facial motion

It has been suggested that acronyms like BBC are processed like real words. This claim has been based on improved performance with acronyms in the Reicher–Wheeler task, the letter string matching task, the visual feature integration task, and the N400 component in event-related potential (ERP) studies. Unfortunately, in all these tasks performance on acronyms resembled performance on pseudowords more than performance on words. To further assess the similarity of acronyms and words, we focused on the meaning of the acronyms and used masked priming to examine whether target words can be primed to the same extent with associatively related acronyms as with associatively related words. Such priming was possible at a stimulus onset asynchrony (SOA) of 84 ms. In addition, the priming of the acronyms did not depend on the letter case in which they were presented: The target word “books” was primed as much by isbn and iSbN as by ISBN.     

Components representation of negative numbers: Evidence from auditory stimuli detection and number classification tasks

Past research suggested that negative numbers could be represented in terms of their components in the visual modality. The present study examined the processing of negative numbers in the auditory modality and whether it is affected by context. Experiment 1 employed a stimuli detection task where only negative numbers were presented binaurally. Experiment 2 employed the same task, but both positive and negative numbers were mixed as cues. A reverse attentional spatial–numerical association of response codes (SNARC) effect for negative numbers was obtained in these two experiments. Experiment 3 employed a number classification task where only negative numbers were presented binaurally. Experiment 4 employed the same task, but both positive and negative numbers were mixed. A reverse SNARC effect for negative numbers was obtained in these two experiments. These findings suggest that negative numbers in the auditory modality are generated from the set of positive numbers, thus supporting a components representation.     

Is adding 48 + 25 and 45 + 28 the same? How addend compatibility influences the strategy execution in mental addition

A recent study revealed that adults frequently start to add two two-digit numbers from the larger one, suggesting that addend magnitudes are compared at an early stage of processing. However, several studies showed that symbolic number comparison involves compatibility effects: Such numerical comparison is easier when the larger number also contains the larger unit (48_25) than in the opposite, incompatible case (45_28). In this context, whether the compatibility between tens and units across operands affects the execution of arithmetic-solving strategies remains an open question. In this study, we used two kinds of verbal protocols to assess how addend compatibility influences the implementation of magnitude-based strategies. We observed that participants started their computations from the larger operand more frequently when solving compatible additions than they did when solving incompatible ones. The presence of a compatibility effect extends the view that multidigit number processing is componential rather than holistic, even in an arithmetic task that did not explicitly require a number magnitude comparison. Further, the findings corroborate the notion that number magnitude is used in mental calculation and influences the way calculation strategies are implemented.
