Book Description
Semantic priming - the improvement in speed or accuracy to respond to a word when it is preceded by a semantically related word - is addressed in this volume, which provides a succinct and in-depth overview of this important phenomenon.

Book Description
The current study examined second language learners and employed a masked semantic priming paradigm paired with a lexical decision task in an attempt to better understand the processes of acquiring semantic information from a second language (L2) and organizing into the lexicon of a learner. Results from previous literature reveal discrepant results, with some studies providing support for the Revised Hierarchical Model (RHM) emphasizing direct translation links from the first language (L1) being essential for second language processing, while other studies find that an L1 is not necessarily needed in order to process semantic information, thus, supporting the Distributed Representation Model (DRM). Of additional interest, were both the role of hemispheric processing and the relationship of working memory on second language semantic integration. Results from our study revealed an asymmetrical priming effect from the L2-L1 direction with better accuracy for targets in the left hemisphere providing support for the RHM.

Book Description
Seminar paper from the year 2019 in the subject Psychology - Cognition, grade: 1,3, University of Wuppertal, language: English, abstract: In order to retrieve information more efficiently and quickly, our central nervous system makes use of implicit preactivation of associative neural networks. In this study, 78 participants were instructed to identify a sequence of word pairs consisting of either German words, nonwords or pseudowords within a lexical decision task. The procedure was carried out under three different conditions: a) no associations within a word pair, b) connection through general second-level cooccurrences, and c) connection through lemmatized second-level cooccurrences. The analysis of variance revealed highly significant differences in reaction time and error rate between lemmatized second-level cooccurrence compared to general second-level cooccurrences. Both, error rate and reaction time, were lower for lemmatized second-level cooccurrences. Stimuli consisting of words with second-level association had a positive effect on the reaction time and error rate. This could be proven due to a stimulus onset asynchrony of 50ms, avoiding semantical competition that could cause inhibitory effects on the reaction time. Linear regression also revealed that lemmatized second-level cooccurrences had a greater influence on the reaction time up to the target and the error rate compared to general second-level cooccurrences. This information could be used to improve models that explain the process of word recognition by adding the influence of the lemmatized second-level cooccurrence.

Book Description
There are now extensive behavioral and neuropsychological evidence to indicate that semantic information of a word can be activated without conscious awareness. However, semantic activation alone may not be sufficient for observing semantic priming effects in masked lexical decision task. In the following study, two tasks were used: lexical decision and semantic categorization. Conscious awareness of the prime was systematically manipulated by varying the duration of the prime and by varying the placement of the mask in the prime-target presentation sequence. Priming effects were observed in the semantic categorization task at prime durations of 42 milliseconds but no semantic priming was observed for the same prime duration in the lexical decision task. However, semantic priming effects began to emerge in lexical decision at the longer prime durations (55 & 69 ms) and under the least effective prime-mask presentation sequences. It is proposed that semantic activation alone is not sufficient for semantic priming effects in the lexical decision task but that central executive involvement is necessary, if only at the lowest level, for facilitatory effects to be observed. Furthermore, no such central executive involvement appears to be required for the semantic categorization task. The priming effects obtained in this task is interpreted in terms of a"decision priming"effect.
