Testing theories of language processing: An empirical investigation of the on-line lexical decision task.

ABSTRACTThis study investigated the possible influence of first language (L1) collocational patterns on second language (L2) collocational processing. A lexical decision task was used to assess whether collocational patterns acceptable in the L1 but not the L2 would still be activated when processing language entirely in the L2. The results revealed no such activation. Furthermore, L2 speakers did not produce accelerated processing for control collocations that were acceptable in the L2 but not the L1. Based on these findings, we put forth some theoretical suggestions regarding recent research indicating accelerated processing for congruent over incongruent collocations. Finally, our NS control group revealed some unexpected tendencies that cannot be easily accounted for with our current understanding of L1 language processing.

The Right

Clinical and neuroscientific studies in healthy volunteers have established that the cerebellum contributes to language comprehension and production. Yet most evidence is correlational and the exact role of the cerebellum remains unclear. The aim of this study was to investigate the role of the right cerebellum in unimpaired language comprehension and production using non-invasive brain stimulation. In this double-blind, sham-controlled experiment, thirty-six healthy participants received anodal or sham transcranial direct current (tDCS) stimulation to the right cerebellum while performing a lexical decision, sentence comprehension, verbal fluency and language-unrelated control task. Results showed that anodal relative to sham tDCS caused faster manual responses in the lexical decision task. Additional exploratory analyses suggest load-specific performance modulation in the sentence comprehension and lexical decision task, with tDCS improving performance in low-load trials of the sentence comprehension task and high-load trials in the lexical decision task. Overall, our findings provide evidence for the involvement of the right posterior cerebellum in comprehension-based language tasks requiring a manual response. Further research is needed to dissociate the influence of task difficulty and timing of the underlying cognitive processes.

Before And After

Abstract. This study measured the effect of emotional states on lexical decision task performance and investigated which underlying components (physiological, attentional orienting, executive, lexical, and/or strategic) are affected. We did this by assessing participants’ performance on a lexical decision task, which they completed before and after an emotional state induction task. The sequence effect, usually produced when participants repeat a task, was significantly smaller in participants who had received one of the three emotion inductions (happiness, sadness, embarrassment) than in control group participants (neutral induction). Using the diffusion model ( Ratcliff, 1978 ) to resolve the data into meaningful parameters that correspond to specific psychological components, we found that emotion induction only modulated the parameter reflecting the physiological and/or attentional orienting components, whereas the executive, lexical, and strategic components were not altered. These results suggest that emotional states have an impact on the low-level mechanisms underlying mental chronometric tasks.

Abstract. The ability to identify and communicate emotions is essential to psychological well-being. Yet research focusing exclusively on emotion concepts has been limited. This study examined nouns that represent emotions (e.g., pleasure, guilt) in comparison to nouns that represent abstract (e.g., wisdom, failure) and concrete entities (e.g., flower, coffin). Twenty-five healthy participants completed a lexical decision task. Event-related potential (ERP) data showed that emotion nouns elicited less pronounced N400 than both abstract and concrete nouns. Further, N400 amplitude differences between emotion and concrete nouns were evident in both hemispheres, whereas the differences between emotion and abstract nouns had a left-lateralized distribution. These findings suggest representational distinctions, possibly in both verbal and imagery systems, between emotion concepts versus other concepts, implications of which for theories of affect representations and for research on affect disorders merit further investigation.
