An Ecological Alternative to Snodgrass & Vanderwart: 360 High Quality Colour Images with Norms for Seven Psycholinguistic Variables

This work presents a new set of 360 high quality colour images belonging to 23 semantic subcategories. Two hundred and thirty-six Spanish speakers named the items and also provided data from seven relevant psycholinguistic variables: age of acquisition, familiarity, manipulability, name agreement, typicality and visual complexity. Furthermore, we also present lexical frequency data derived from Internet search hits. Apart from the high number of variables evaluated, knowing that it affects the processing of stimuli, this new set presents important advantages over other similar image corpi: (a) this corpus presents a broad number of subcategories and images; for example, this will permit researchers to select stimuli of appropriate difficulty as required, (e.g., to deal with problems derived from ceiling effects); (b) the fact of using coloured stimuli provides a more realistic, ecologically-valid, representation of real life objects. In sum, this set of stimuli provides a useful tool for research on visual object-and word- processing, both in neurological patients and in healthy controls.

Affective norms of 875 Spanish words for five discrete emotional categories and two emotional dimensions.

In the present study, we introduce affective norms for a new set of Spanish words, the Madrid Affective Database for Spanish (MADS), that were scored on two emotional dimensions (valence and arousal) and on five discrete emotional categories (happiness, anger, sadness, fear, and disgust), as well as on concreteness, by 660 Spanish native speakers. Measures of several objective psycholinguistic variables—grammatical class, word frequency, number of letters, and number of syllables—for the words are also included. We observed high split-half reliabilities for every emotional variable and a strong quadratic relationship between valence and arousal. Additional analyses revealed several associations between the affective dimensions and discrete emotions, as well as with some psycholinguistic variables. This new corpus complements and extends prior databases in Spanish and allows for designing new experiments investigating the influence of affective content in language processing under both dimensional and discrete theoretical conceptions of emotion.

Subliminal Gestalt grouping: Evidence of perceptual grouping by proximity and similarity in absence of conscious perception

Previous studies making use of indirect processing measures have shown that perceptual grouping can occur outside the focus of attention. However, no previous study has examined the possibility of subliminal processing of perceptual grouping. The present work steps forward in the study of perceptual organization, reporting direct evidence of subliminal processing of Gestalt patterns. In two masked priming experiments, Gestalt patterns grouped by proximity or similarity that induced either a horizontal or vertical global orientation of the stimuli were presented as masked primes and followed by visible targets that could be congruent or incongruent with the orientation of the primes. The results showed a reliable priming effect in the complete absence of prime awareness for both proximity and similarity grouping principles. These findings suggest that a phenomenal report of the Gestalt pattern is not mandatory to observe an effect on the response based on the global properties of Gestalt stimuli.

Spanish norms for age of acquisition, concept familiarity, lexical frequency, manipulability, typicality, and other variables for 820 words from 14 living/nonliving concepts

This article presents a new corpus of 820 words pertaining to 14 semantic categories, 7 natural (animals, body parts, insects, flowers, fruits, trees, and vegetables) and 7 man-made (buildings, clothing, furniture, kitchen utensils, musical instruments, tools, and vehicles); each word in the database was collected empirically in a previous exemplar generation study. In the present study, 152 Spanish speakers provided data for four psycholinguistic variables known to affect lexical-semantic processing in both neurologically intact and brain-damaged participants: age of acquisition, familiarity, manipulability, and typicality. Furthermore, we collected lexical frequency data derived from Internet search hits, plus three additional Spanish lexical frequency indexes. Word length, number of syllables, and the proportion of respondents citing the exemplar as a category member—which can be useful as an additional measure of typicality—are also provided. Reliability and validity indexes showed that our items display characteristics similar to those of other corpora. Overall, this new corpus of words provides a useful tool for scientists engaged in cognitive- and neuroscience-based research focused on examining language, memory, and object processing.

Interactions between Intrinsic Principles of Similarity and Proximity and Extrinsic Principle of Common Region in Visual Perception

The interactions between intrinsic grouping principles (by proximity or by similarity in shape or luminance) and extrinsic grouping by common region were examined by presenting both principles acting alone or conjoined with another principle in visual patterns. The procedure used in our study closely mirrored that of Quinlan and Wilton (1998 Perception 27 417 – 430). However, in the present experiment, the intrinsic and extrinsic grouping principles involved had similar relative salience in order to avoid their possible effects on interactions. The results showed that the grouping effect of conjoined cooperating principles was greater than that of either principle acting alone, and the grouping effect of conjoined competing principles was lower than that of either principle operating alone. Compatibility of data with additive effects of grouping principles has been examined.

A set of high quality colour images with Spanish norms for seven relevant psycholinguistic variables: The Nombela naming test

ABSTRACT This paper presents a new corpus of 140 high quality colour images belonging to 14 subcategories and covering a range of naming difficulty. One hundred and six Spanish speakers named the items and provided data for several psycholinguistic variables: age of acquisition, familiarity, manipulability, name agreement, typicality and visual complexity. Furthermore, we also present lexical frequency data derived internet search hits. Apart from the large number of variables evaluated, these stimuli present an important advantage with respect to other comparable image corpora in so far as naming performance in healthy individuals is less prone to ceiling effect problems. Reliability and validity indexes showed that our items display similar psycholinguistic characteristics to those of other corpora. In sum, this set of ecologically valid stimuli provides a useful tool for scientists engaged in cognitive and neuroscience-based research.

The activation of representative emotional verbal contexts interacts with vertical spatial axis

Abstract Several experimental studies have shown that there exists an association between emotion words and the vertical spatial axis. However, the specific conditions under which this conceptual–physical interaction emerges are still unknown, and no study has been devised to test whether longer linguistic units than words can lead to a mapping of emotions on vertical space. In Experiment 1, Spanish and Colombian participants performed a representative verbal emotional contexts production task (RVEC task) requiring participants to produce RVEC for the emotions of joy, sadness, surprise, anger, fear, and disgust. The results showed gender and cultural differences regarding the average number of RVEC produced. The most representative contexts of joy and sadness obtained in Experiment 1 were used in Experiment 2 in a novel spatial–emotional congruency verification task (SECV task). After reading a sentence, the participants had to judge whether a probe word, displayed in either a high or low position on the screen, was congruent or incongruent with the previous sentence. The question was whether the emotion induced by the sentence could modulate the responses to the probes as a function of their position in a vertical axis by means of a metaphorical conceptual–spatial association. Overall, the results indicate that a mapping of emotions on vertical space can occur for linguistic units larger than words, but only when the task demands an explicit affective evaluation of the target.

Longitudinal patterns of fluency impairment in dementia: The role of domain and “nuisance variables”

Background: The potential differential impact of Alzheimers disease (AD) across semantic categories/domains (i.e., living/nonliving) has been debated extensively in the past 30 years. An important methodological consideration in this area is the issue of whether category effects are genuine or a by-product of intrinsic properties of items, i.e., nuisance variables (NVs). Aims: The studys aim was to investigate whether NVs versus semantic domain of words generated in a semantic fluency task better predict semantic impairment. Methods & Procedures: We examined semantic fluency performance of demographically matched AD patients and controls. AD patients were longitudinally examined over a 2-year period. Norms of all NVs known to differ across domains were obtained for each word generated; influence of domain was also studied. Outcomes & Results: AD patients generated fewer words than controls. However, both groups showed fairly similar performance: more familiar words, with earlier acquisition, and representing concepts with higher manipulability were generated. Domain exerted similar influence on semantic fluency performance in controls and patients at initial evaluation, but it did not influence performance as the disease advanced. In contrast, the role of familiarity increased with disease progression. Conclusions: The role of NVs—especially familiarity—appears to be, comparatively, a more relevant predictor of longitudinal deterioration than semantic domain. Knowing which variables within a semantic fluency task longitudinally predict cognitive decline is a useful clinical tool and could possibly be a cognitive marker to improve accuracy of neuropsychological evaluation of patients with probable AD.

The Madrid Affective Database for Spanish (MADS) : ratings of dominance, familiarity, subjective age of acquisition and sensory experience

The current study presents ratings by 540 Spanish native speakers for dominance, familiarity, subjective age of acquisition (AoA), and sensory experience (SER) for the 875 Spanish words included in the Madrid Affective Database for Spanish (MADS). The norms can be downloaded as supplementary materials for this manuscript from https://figshare.com/s/8e7b445b729527262c88 These ratings may be of potential relevance to researches who are interested in characterizing the interplay between language and emotion. Additionally, with the aim of investigating how the affective features interact with the lexicosemantic properties of words, we performed correlational analyses between norms for familiarity, subjective AoA and SER, and scores for those affective variables which are currently included in the MADs. A distinct pattern of significant correlations with affective features was found for different lexicosemantic variables. These results show that familiarity, subjective AoA and SERs may have independent effects on the processing of emotional words. They also suggest that these psycholinguistic variables should be fully considered when formulating theoretical approaches to the processing of affective language.

Development of the updating executive function: From 7-year-olds to young adults.

Updating information in working memory (WM) is a critical executive function responsible both for continuously replacing outdated information with new relevant data and to suppress or inhibit content that is no longer relevant according to task demands. The goal of the present research is twofold: First, we aimed to study updating development in 548 participants of 4 different age ranges--7-, 11-, and 15-year-olds and young adults--using the updating task devised by R. De Beni and P. Palladino (2004), which allows differentiating maintenance and inhibition processes. Second, we attempted to determine the relation between these processes across development as well as the differentiation among different types of inhibition processes tapped by this task. Results showed that there was an improvement of memory performance with age along with an upgrading of inhibitory efficiency. However, whereas in memory performance, a progressive increase was observed until the age of 15 years followed by stabilization, in inhibition, a continuous progressive increase was observed until young adulthood. Importantly, results showed that development of the different inhibitory mechanisms does not progress equally. All the groups committed more errors related to inefficient suppression mechanisms in WM than errors related to control of long-term memory interference. Principal component analysis showed that updating implies different subprocesses: active maintenance/suppression of information in WM and control of proactive interference. Developmental trajectories showed that the maintenance/suppression of information in the WM component continues to develop far beyond adolescence but that proactive interference control is responsible for variations in updating across development.
