中文阅读预视加工中的词频和预测性效应及其对词切分的启示:基于眼动的证据 总被引:1,自引:0,他引:1
研究采用眼动随动显示技术考察中文阅读预视加工中的词汇加工问题。前三项实验发现,剥夺预视加工的掩蔽条件、正确提示词n+1右侧边界的掩蔽条件以及不能提示词n+1右侧边界的掩蔽条件都不影响词频效应,说明中文读者对词n+1处文字的预视加工达不到词汇水平。实验4考察剥夺预视加工的掩蔽条件、提示词n+1右侧边界的掩蔽条件对预测性效应的影响,结果发现,剥夺预视加工完全消除预测性效应,提示词n+1右侧边界则减少预测性效应,说明对词汇的预期加工是中文读者切分词n+1的参考线索。综合4项实验结果可知,中文读者较难通过自下而上的文字识别切分词n+1,自上而下的词汇预期则是切分词n+1的加工形式。 相似文献

Learning to solve a class of problems can be characterized as a search through a space of hypotheses about the rules for solving these problems. A series of four experiments studied how different learning conditions affected the search among hypotheses about the solution rule for a simple computational problem. Experiment 1 showed that a problem property such as computational difficulty of the rules biased the search process and so affected learning. Experiment 2 examined the impact of examples as instructional tools and found that their effectiveness was determined by whether they uniquely pointed to the correct rule. Experiment 3 compared verbal directions with examples and found that both could guide search. The final experiment tried to improve learning by using more explicit verbal directions or by adding scaffolding to the example. While both manipulations improved learning, learning still took the form of a search through a hypothesis space of possible rules. We describe a model that embodies two assumptions: (1) the instruction can bias the rules participants hypothesize rather than directly be encoded into a rule; (2) participants do not have memory for past wrong hypotheses and are likely to retry them. These assumptions are realized in a Markov model that fits all the data by estimating two sets of probabilities. First, the learning condition induced one set of Start probabilities of trying various rules. Second, should this first hypothesis prove wrong, the learning condition induced a second set of Choice probabilities of considering various rules. These findings broaden our understanding of effective instruction and provide implications for instructional design. 相似文献

Prospective memory refers to the ability to plan and execute future intentions. A burgeoning body of research indicates that a significant proportion of the variability in prospective memory performance can be accounted for by personality traits, with two recent studies revealing that the various dimensions of impulsivity measured by the Barratt Impulsivity Scale‐11 (BIS‐11) are related to prospective memory failures. The present study was conducted to examine which dimensions of impulsivity indexed by the BIS‐11 and UPPS‐P relate to prospective memory failures and which dimensions of impulsivity contribute unique variance in the prediction of prospective memory failures. A large sample (N = 662) of students completed the BIS‐11, UPPS‐P, Prospective Memory Questionnaire and a habitual prospective memory test. Consistent correlations between six of the seven measures of impulsivity and prospective memory failures were found. Regression analyses further revealed that lack of perseverance, emotional urgency and attentional impulsivity were reliable and unique predictors of prospective memory failures. Thus, difficulty remaining focused on tasks (especially long, boring or difficult tasks); lack of forethought, planning and distaste for challenging tasks; and tendencies to behave impulsively under conditions of strong affect relate most strongly to prospective memory failures.

AbstractThis article presents a brief overview of a family resilience conceptual framework, grounded in a multi-level developmental systems orientation. A family systems perspective broadens attention to resources for individual resilience throughout the family network of relationships. The concept of family resilience refers to the family as a functional system, impacted by highly stressful events and social contexts, and in turn, facilitating the positive adaptation of all members and strengthening the family unit. A research-informed map of key processes in family resilience is outlined, highlighting the recursive and synergistic influences of transactional processes within families and with their social environment. Varied process elements may be more or less useful, depending on different adverse situations over time, with a major crisis, trauma, or loss; disruptive transitions; or chronic multi-stress conditions. This perspective is attuned to the diversity of family cultures and structures, their resources and constraints, salient socio-cultural and developmental influences, and the viability of varied pathways in resilience. 相似文献

In an eye-tracking experiment we examined whether Chinese readers were sensitive to information concerning how often a Chinese character appears as a single-character word versus the first character in a two-character word, and whether readers use this information to segment words and adjust the amount of parafoveal processing of subsequent characters during reading. Participants read sentences containing a two-character target word with its first character more or less likely to be a single-character word. The boundary paradigm was used. The boundary appeared between the first character and the second character of the target word, and we manipulated whether readers saw an identity or a pseudocharacter preview of the second character of the target. Linear mixed-effects models revealed reduced preview benefit from the second character when the first character was more likely to be a single-character word. This suggests that Chinese readers use probabilistic combinatorial information about the likelihood of a Chinese character being single-character word or a two-character word online to modulate the extent of parafoveal processing. 相似文献

Involuntary autobiographical memories come to mind effortlessly and unintended, but the mechanisms of their retrieval are not fully understood. We hypothesize that involuntary retrieval depends on memories that are highly accessible (e.g., intense, unusual, recent, rehearsed), while the elaborate search that characterizes voluntary retrieval also produces memories that are mundane, repeated or distant – memories with low accessibility. Previous research provides some evidence for this ‘threshold hypothesis’. However, in almost every prior study, participants have been instructed to report only memories while ignoring other thoughts. It is possible that such an instruction can modify the phenomenological characteristics of involuntary memories. This study aimed to investigate the effects of retrieval intentionality (i.e., wanting to retrieve a memory) and selective monitoring (i.e., instructions to report only memories) on the phenomenology of autobiographical memories. Participants were instructed to (1) intentionally retrieve autobiographical memories, (2) intentionally retrieve any type of thought (3) wait for an autobiographical memory to spontaneously appear, or (4) wait for any type of thought to spontaneously appear. They rated the mental content on a number of phenomenological characteristics both during retrieval and retrospectively following retrieval. The results support the prediction that highly accessible memories mostly enter awareness unintended and without selective monitoring, while memories with low accessibility rely on intention and selective monitoring. We discuss the implications of these effects. 相似文献

Environmental organizations have a key role in addressing environmental degradation and promoting ecologically and socially sustainable societies. Psychosocial processes underpin their work, however, empirical studies of these processes remain underdeveloped. This paper presents the first stage of a community psychology study involving in-depth interviews with leaders in environmental organizations. Qualitative analysis revealed a framework of five types of psychosocial processes that assist environmental organizations to achieve a range of outcomes, namely: problem analysis; influencing decision-making; inter-organizational relationships; community participation and knowledge transfer. These psychosocial processes were used in substantially different ways depending on the organizations' orientation. Three key orientations towards outcomes were evident: on-ground conservation, developing innovation in specialist areas and transforming wider social institutions. The findings provide a model of the psychosocial processes involved in fostering sustainable futures and exemplify the contribution of community psychology to this critical global issue. 相似文献
