In the present study, the significance of category-related brain activations as an index of semantic memory structure was assessed within a repetition-priming paradigm during a lexical decision task. The interpretation of category-related effects has been debated since previous studies observed category-related brain activity mainly in tasks requiring explicit semantic categorization. Furthermore, categories were frequently associated with behavioral performance differences, which could have influenced the pattern of brain activation. Event-related potentials (ERPs) to words denoting objects from artifactual (e.g., tools) and natural categories (e.g., animals) were recorded while subjects were presented with words and pseudowords as distracters, which were repeatedly presented. Category-related ERP differences emerged in the time window of the N400, an electrophysiological index of semantic processing, over occipito-parietal and fronto-central regions as well as in the following window of a late positive potential. Repetition priming modulated these category-related ERP effects whereas behavioral repetition priming (faster reactions to repeated words) was comparable for both categories. Differences in ERP repetition effects were specifically due to diminished category-related activity at repeated presentation. The present results show that category-related brain activation is not confined to tasks requiring explicit semantic categorization. Most importantly, the study demonstrates that category-related brain activation can be specifically modulated by repetition priming in the absence of corresponding behavioral performance differences. These findings therefore substantiate the significance of category-related brain activations as reflections of semantic memory structure and support the notion of multiple cortical semantic systems.

Fluency Task

Openness to experience—the enjoyment of novel experiences and ideas—has many connections to cognitive processes. People high in openness to experience, for example, tend to be more creative and have broader general knowledge than people low in openness to experience. In the current study, we use a network science approach to examine if the organization of semantic memory differs between high and low groups of openness to experience. A sample of 516 adults completed measures of openness to experience (from the NEO Five–Factor Inventory–3 and Big Five Aspect Scales) and a semantic verbal fluency task. Next, the sample was split into half to form high ( n = 258) and low ( n = 258) openness to experience groups. Semantic networks were then constructed on the basis of their verbal fluency responses. Our results revealed that the high openness to experience group's network was more interconnected, flexible, and had better local organization of associations than the low openness to experience group. We also found that the high openness to experience group generated more responses on average and provided more unique responses than the low openness to experience group. Taken together, our results indicate that openness to experience is related to semantic memory structure. © 2018 European Association of Personality Psychology

Summary: The Wechsler Memory Scale (WMS) is a laboratory-based memory test that has been criticized for its lack of ecological validity and for not testing long-term memory. A more recent memory test, which aims at testing everyday memory, is the Rivermead Behavioral Memory Test (RBMT); it tests prospective memory and other forms of memory not tapped by WMS. However, even this test does not capture all aspects of everyday memory problems often reported by adults. These problems are the object of the Everyday Memory Questionnaire (EMQ). This study aimed at identifying the relationships between these three memory tests. The differential effect of Alzheimer's disease (AD) on the above relationships was also studied. The sample consisted of 233 healthy adults (20 to 75+ years of age) and 39 AD patients (50 to 75 years of age). Confirmatory factor analysis revealed the following latent factors: Verbal Memory, Visual Reconstruction, Orientation, Message (action embedded in spatial context), Visual Recognition, Spatial Memory, New Learning/Association Forming, Prospective/Episodic Memory, and Metamemory. These first-order factors were further explained by two second-order factors: Semantic Memory and Coordination of Semantic and Visuo-Spatial Memory. This basic structure was preserved in the sample of AD patients, although AD patients performed less well on the WMS and the RBMT. Some interesting findings regarding semantic memory, face recognition, and metamemory in AD patients are also reported. Age, education, but no gender effects on memory performance were also detected.
