Title Participants Abstract "Semantic gender: Norms for 24,000 Dutch words and its role in word meaning" "Hendrik Vankrunkelsven, Gert Storms" "Semantic gender norms are presented for 24,037 Dutch words. Eighty participants rated 6017 words each on a five-point Likert scale ranging from feminine to masculine. Each word was rated by ten male and ten female participants. The collected norms show high reliability and correlate well with similar norms in English. We show that semantic gender is distinct from other lexical dimensions such as valence, arousal, dominance, concreteness, and age of acquisition. Semantic gender is not the same as the grammatical gender of words, either. The collected norms can be predicted accurately using a semantic space based on word association data. A dimension explaining a good amount of variance is present in this space, indicating that semantic gender is an important component of the human meaning system." "If My Memory Serves Me Well: Investigating My Memory for the Past 24 Years." "Gert Storms" "This paper reports on a study of my autobiographical memory for 2691 notes recorded over 24 years in my diary, without any intention to ever use the notes as test material. I never read any of the notes again until the start of the memory study. I remembered less than two thirds of the recorded events and the retention curve showed a curvilinear shape. I dated 2% of the described events correctly but misdated on average about one and a half year, with an equal number of over and underestimations of the event age. Retention correlated significantly with ratings of salience, emotional involvement, pleasantness, event rehearsal and self-relatedness, but not with intimacy. Dating accuracy correlated with salience, pleasantness, intimacy and event rehearsal, but not with emotional involvement or self-relatedness. Regression analyses showed that event rehearsal was the best predictor of retention and dating, but the predictive value of other ratings was dependent on the content of the recorded events." "Independency of Coding for Affective Similarities and for Word Co-occurrences in Temporal Perisylvian Neocortex" "Gert Storms, Patrick Dupont, Rik Vandenberghe" "Word valence is one of the principal dimensions in the organization of word meaning. Co-occurrence-based similarities calculated by predictive natural language processing models are relatively poor at representing affective content, but very powerful in their own way. Here, we determined how these two canonical but distinct ways of representing word meaning relate to each other in the human brain both functionally and neuroanatomically. We re-analysed an fMRI study of word valence. A co-occurrence-based model was used and the correlation with the similarity of brain activity patterns was compared to that of affective similarities. The correlation between affective and co-occurrence-based similarities was low (r = 0.065), confirming that affect was captured poorly by co-occurrence modelling. In a whole-brain representational similarity analysis, word embedding similarities correlated significantly with the similarity between activity patterns in a region confined to the superior temporal sulcus to the left, and to a lesser degree to the right. Affective word similarities correlated with the similarity in activity patterns in this same region, confirming previous findings. The affective similarity effect extended more widely beyond the superior temporal cortex than the effect of co-occurrence-based similarities did. The effect of co-occurrence-based similarities remained unaltered after partialling out the effect of affective similarities (and vice versa). To conclude, different aspects of word meaning, derived from affective judgements or from word co-occurrences, are represented in superior temporal language cortex in a neuroanatomically overlapping but functionally independent manner." "Klokkenluiden in de wetenschap. In het hol van de leeuw." "Steven De Peuter, Gert Storms" "Research integrity has received increased attention, in the literature as well as in policy. A host of initiatives is supporting its promotion. However, misconduct will not cease to exist and needs to be reported, by whistleblowers. It takes a lot of courage to blow the whistle as it can have an enormous impact on the whistleblower’s career and personal well-being – and that of colleagues and researchers associated with the perpetrator. Therefore, it is important to be cognisant of the stressful process that accompanies the act of whistleblowing, to provide clear and accessible procedures to report misconduct, and to support whistleblowers throughout the process. Furthermore, it is essential that appropriate whistleblower protection measures are in place and enforced. Based on the current review of the literature, we provide some recommendations for policy and argue that an obligation to report scientific misconduct would currently do more harm than good." "Orienting to Different Dimensions of Word Meaning Alters the Representation of Word Meaning in Early Processing Regions" "Karen Meersmans, Gert Storms, Patrick Dupont, Rik Vandenberghe" "Conscious processing of word meaning can be guided by attention. In this event-related functional magnetic resonance imaging study in 22 healthy young volunteers, we examined in which regions orienting attention to two fundamental and generic dimensions of word meaning, concreteness versus valence, alters the semantic representations coded in activity patterns. The stimuli consisted of 120 nouns in written or spoken modality which varied factorially along the concreteness and valence axis. Participants performed a forced-choice judgement of either concreteness or valence. Rostral and subgenual anterior cingulate were strongly activated during valence judgement, and precuneus and the dorsal attention network during concreteness judgement. Task and stimulus type interacted in right posterior fusiform gyrus, left lingual gyrus, precuneus, and insula. In the right posterior fusiform gyrus and the left lingual gyrus, the correlation between the pairwise similarity in activity patterns evoked by words and the pairwise distance in valence and concreteness was modulated by the direction of attention, word valence or concreteness. The data indicate that orienting attention to basic dimensions of word meaning exerts effects on the representation of word meaning in more peripheral nodes, such as the ventral occipital cortex, rather than the core perisylvian language regions." "Guessing words: A Comparison of Text Corpus and Word Association Models as the Basis for the Mental Lexicon" "Hendrik Vankrunkelsven, Gert Storms" "Multiple accounts have been proposed to model the mental lexicon, and these models have mainly been validated by comparing how well they can describe human data derived in an experimental setting. Alternatively, we pre-sent two experiments where word stimuli were generated using different models and compare their quality in a familiar word guessing game. A text-corpus-based model and a word association model were used to generate lists of closely related words to a target word. Consecutively, these words were used as hints in a word guessing game where the aim was to find the target word. Both models succeeded in generating good quality hints, but those generated from the word association model led to more accurate responses and fewer hints needed. Potential explana-tions for why the word association model provided a better approximation of the mental lexicon are discussed." "Een inleiding in de psychologie in 11 ¾ hoofdstukken" "Gert Storms" "Visual and Affective Multimodal Models of Word Meaning in Language and Mind" "Simon De Deyne" "One of the main limitations of natural language-based approaches to meaning is that they do not incorporate multimodal representations the way humans do. In this study, we evaluate how well different kinds of models account for people's representations of both concrete and abstract concepts. The models we compare include unimodal distributional linguistic models as well as multimodal models which combine linguistic with perceptual or affective information. There are two types of linguistic models: those based on text corpora and those derived from word association data. We present two new studies and a reanalysis of a series of previous studies. The studies demonstrate that both visual and affective multimodal models better capture behavior that reflects human representations than unimodal linguistic models. The size of the multimodal advantage depends on the nature of semantic representations involved, and it is especially pronounced for basic-level concepts that belong to the same superordinate category. Additional visual and affective features improve the accuracy of linguistic models based on text corpora more than those based on word associations; this suggests systematic qualitative differences between what information is encoded in natural language versus what information is reflected in word associations. Altogether, our work presents new evidence that multimodal information is important for capturing both abstract and concrete words and that fully representing word meaning requires more than purely linguistic information. Implications for both embodied and distributional views of semantic representation are discussed." "A Comparison of the Spatial Arrangement Method and the Total-Set Pairwise Rating Method for Obtaining Similarity Data in the Conceptual Domain" "Steven Verheyen, Gert Storms" "We compare two methods for obtaining similarity data in the conceptual domain. In the Spatial Arrangement Method (SpAM), participants organize stimuli on a computer screen so that the distance between stimuli represents their perceived dissimilarity. In Total-Set Pairwise Rating Method (PRaM), participants rate the (dis)similarity of all pairs of stimuli on a Likert scale. In each of three studies, we had participants indicate the similarity of four sets of conceptual stimuli with either PRaM or SpAM. Studies 1 and 2 confirm two caveats that have been raised for SpAM. (i) While SpAM takes significantly less time to complete than PRaM, it yields less reliable data than PRaM does. (ii) Because of the spatial manner in which similarity is measured in SpAM, the method is biased against feature representations. Despite these differences, averaging SpAM and PRaM dissimilarity data across participants yields comparable aggregate data. Study 3 shows that by having participants only judge half of the pairs in PRaM, its duration can be significantly reduced, without affecting the dissimilarity distribution, but at the cost of a smaller reliability. Having participants arrange multiple subsets of the stimuli does not do away with the spatial bias of SpAM." "Therapeuten Verhalen" "Peter Rober, Gert Storms"
