A normative study for photographs of celebrities in Spain

[EN]Research on familiar faces has recurrently been conducted in different domains, such as, psycholinguistics, memory, attention, face processing, aging studies, etc. In general, photo graphs of celebrities, their proper names, or their occupations have been the materials mainly employed in those types of studies. These stimuli are, however, very constrained by the geographic and sociocultural contexts in which the studies are conducted, and, in spite of their relevance for psychological research, there are no normative studies for celebrities in Spain. With the aim of filling this gap, the photographs and names of the 118 most fre quently produced celebrities in Spain were collected. For each celebrity, values for 13 differ ent indices (including psycholinguistic properties, naming times, and emotional indicators) were obtained from a young adult Spanish sample. Regression analyses on the data indi cated that the main determinant in naming times and ToTs was the percentage of correct responses. Face agreement was also a significant predictor of ToTs. Results were com pared with previous celebrity norms in other languages, and discussed in relation to the cur rent models of face processing. These norms are likely to make a useful contribution to the design of more controlled research and applied tools in Psychology

Normative data for the 56 categories of Battig and Montague (1969) in Spanish

[EN]Knowledge of specific characteristics of verbal ma terial is imperative in cognitive research, and this need calls for periodical updating of normative data. With this aim, and considering that the most recent Spanish-language category norms for adults date back to more than 30 years ago, and that they do not include some very common categories, a new normative study was conducted. In this study, production data for exemplars in the 56 categories of Battig and Montague (Journal of Experimental Psychology, 80, 1-46, 1969) were collected from a pool of 284 young adults who were native speakers of Spanish using an exemplar production task. With the goal of providing a useful tool for cognitive research to be conducted with Spanish-speaking samples, indices of frequency, rank, and lexical availability for the exemplars of each category are provided in a computerized database. The norms described are available for downloading assupplemental material with this article

Retrieval-induced forgetting in perceptually driven memory tests

[EN]Recent data (T. J. Perfect, C. J. A. Moulin, M. A. Conway, & E. Perry, 2002) have suggested that retrieval-induced forgetting (RIF) depends on conceptual memory because the effect is not found in perceptually driven tasks. In 3 experiments, the authors aimed to show that the presence of RIF depends on whether the procedure induces appropriate transfer between representations and competition rather than on the nature of the final test. The authors adapted the standard paradigm to introduce lexical categories (words that shared the first 2 letters) at study and practice. Direct and indirect fragment completion tests were used at retrieval. The results showed significant RIF effects in perceptually driven tasks. Furthermore, they indicated that the presence of RIF effects depended on using adequate cuing to induce competition during the retrieval practice and on the final memory test tapping the inhibited representation.Ministerio de Educación y Cienci

Forgetting “Novel” but Not “Dragon”: The Role of Age of Acquisition on Intentional and Incidental Forgetting

Two experiments studied how the age at which words are acquired (Age of Acquisition, AoA) modulates forgetting. Experiment 1 employed the retrieval-practice paradigm to test the effect of AoA on the incidental forgetting that emerges after solving competition during retrieval (i.e., retrieval-induced forgetting, RIF). Standard RIF appeared with late-acquired words, but this effect disappeared with early-acquired words. Experiment 2 evaluated the effect of AoA on intentional forgetting by employing the list-method directed forgetting paradigm. Results showed a standard directed forgetting effect only when the to-be-forgotten words were late-acquired words. These findings point to the prominent role of AoA in forgetting processes.This research was supported by grants from the Spanish Ministry of Economy and Competitiveness (http://www.mineco.gob.es/portal/site/mineco/?lang_choosen=en) to AM (PSI2013-46033-P), TB (PSI2012-33625), and CJG-A (PSI2011-25797), and from the Ministry of Science (http://www.mineco.gob.es/portal/site/mineco/?lang_choosen=en) (EDU2008-01111) and the Andalusian Government (http://www.juntadeandalucia.es/) (P12-CTS-2369) to TB

The modulating effect of education on semantic interference during healthy aging

Aging has traditionally been related to impairments in name retrieval. These impairments have usually been explained by a phonological transmission deficit hypothesis or by an inhibitory deficit hypothesis. This decline can, however, be modulated by the educational level of the sample. This study analyzed the possible role of these approaches in explaining both object and face naming impairments during aging. Older adults with low and high educational level and young adults with high educational level were asked to repeatedly name objects or famous people using the semantic-blocking paradigm. We compared naming when exemplars were presented in a semantically homogeneous or in a semantically heterogeneous context. Results revealed significantly slower rates of both face and object naming in the homogeneous context (i.e., semantic interference), with a stronger effect for face naming. Interestingly, the group of older adults with a lower educational level showed an increased semantic interference effect during face naming. These findings suggest the joint work of the two mechanisms proposed to explain age-related naming difficulties, i.e., the inhibitory deficit and the transmission deficit hypothesis. Therefore, the stronger vulnerability to semantic interference in the lower educated older adult sample would possibly point to a failure in the inhibitory mechanisms in charge of interference resolution, as proposed by the inhibitory deficit hypothesis. In addition, the fact that this interference effect was mainly restricted to face naming and not to object naming would be consistent with the increased age-related difficulties during proper name retrieval, as suggested by the transmission deficit hypothesis.This research was supported by grants PSI2013-46033-P to A.M., PSI2015-65502-C2-1-P to M.T.B., PCIN-2015-165-C02-01 to D.P., PSI2017-89324-C2-1-P to DP from the Spanish Ministry of Economy and Competitiveness (http://www.mineco.gob.es/)

¿Perjudica Antonio Banderas a Javier Bardem?: La competición semántica en tareas de nombrado de personas

En este experimento se ha investigado la presencia de competición semántica en el nombrado de fotografías de personas conocidas. Un estudio previo de Vitkovitch, Potton, Bakogianni y Kinch (2006) mostró el efecto contrario de facilitación semántica en el nombrado de la fotografía de una persona conocida tras la recuperación, tres ensayos antes, del nombre de otra persona relacionada categorialmente. En el experimento actual se ha replicado este efecto de facilitación semántica en el nombrado de fotografías de personas relacionadas observado por Vitkovitch et al. Sin embargo, se ha observado que este efecto de facilitación semántica disminuía cuando aumentaba el número de personas nombradas de la misma categoría. Estos resultados sugieren que el nombrado de caras, de igual modo que el nombrado de objetos, está semánticamente mediado y es vulnerable a procesos de interferencia tal y como predicen los modelos de tipo serial

Sex, menstrual cycle, and hormonal contraceptives influences on global–local processing

This study was supported by the Spanish Ministry of Economy, Industry and Competitiveness (National I + D Plan: PSI2017–89324-C2–1- P and PSI2017–89324-C2–2-P). Funding for open access charge: Universidad de Granada / CBUA.The effect of sex hormones on global–local tasks has rarely been studied, offering, when done, conflicting results possibly modulated by the congruency between hierarchical stimuli, and by the attentional demands. Here, we examined the global advantage (GA) effect in men (with high testosterone levels), women in the mid-luteal phase (with high levels of estradiol and progesterone), in the ovulatory phase (with high estradiol but low progesterone levels); and in the early follicular phase and with hormonal contraceptive (HC) use (with low sex hormone levels). The level of processing (global–local), the congruency (congruent vs. incongruent), and attentional demands (divided vs. selective) were manipulated. The divided-incongruent condition was sensible to estradiol and progesterone levels and, in this condition, mid-luteal women performed more locally while men performed more globally. The selective-incongruent condition was sensible to the testosterone level and, in this condition, men were faster. The HC group showed a congruency effect in the GA reaction times (RTs) during both, divided and selective conditions. Finally, the GA RTs of the ovulatory group differed from the early follicular and mid-luteal groups only in the congruent-selective condition, but the performance was not related with sex hormone levels. This result is interpreted in relation with the brain effects of estradiol in the absence but not in the presence of progesterone. Thus, sex, menstrual cycle, HC, task difficulty and sex hormones seem to modulate performance in the global–local task. These factors represent an important source of variability in studies focused on the processing of hierarchical stimuli and allow apparently inconsistent data to be explained.Spanish Ministry of Economy, Industry and Competitiveness (National I + D Plan: PSI2017–89324-C2–1- P and PSI2017–89324-C2–2-P)Universidad de Granada / CBU

Prospective memory in bilinguals and monolinguals: ERP and behavioural correlates of prospective processing in bilinguals

Prospective memory (PM) allows us to form intentions and execute them in the future. Successful retrieval of prospective intentions depends on adequate context monitoring and disengagement from the ongoing task. These processes are also central in predicting incoming language information and guiding language production in bilinguals. We investigated if different bilingual experiences (early/late bilinguals, monolinguals) modulate performance in PM tasks that varied in attentional requirements (focal vs. non-focal). Behavioural and eventrelated potential (ERP) results indicated that early bilinguals differed from late bilinguals and monolinguals in how they performed the prospective task. Specifically, they showed larger differences between the ongoing activity and the prospective task in the N300 and P3b components when performing the more difficult non-focal PM task, indicating that they engaged in monitoring/updating to adapt to the task’s demands. These differences were not observed in late bilinguals and monolinguals, suggesting that prospective processing is dependent on the bilingual experience.Spanish Government FPU17/03378Junta de Andalucia PSI 2017-89324-C2-2-P PGC2018-093786-B-I00 30B51801 A-CTS-111-UGR18/B-CTS-384-UGR20/P20_0010

Medial prefrontal theta oscillations track the time course of interference during selective memory retrieval

Memory retrieval is often challenged by other irrelevant competing memories that cause interference. This phenomenon is typically studied with the retrieval practice paradigm in which a category cue (e.g., Fruits) is presented together with an item-specific cue (e.g., Or::). Presentation of the category cue usually induces interference by reactivating competing memories (e.g., Banana, Apple, etc.), which is thought to be solved by means of inhibition, leading to retrieval-induced forgetting of these competing memories. Previous studies associated interference with an increase in medial prefrontal theta band (4–8 Hz) oscillations, but these studies could not disentangle the interference from the inhibition processes. We here used a retrieval practice procedure in which the category cue was presented before the item-specific cue to disentangle the interference from the inhibition signal. Furthermore, a competitive retrieval condition was contrasted with a noncompetitive condition. At a behavioral level, retrieval-induced forgetting was found in the competitive but not in the noncompetitive condition. At a neural level, presentation of the category cue elicited higher levels of theta power in the competitive condition, when compared with the noncompetitive retrieval condition. Importantly, this difference was localized to the ACC, which has been associated with the detection and mediation of interference. Additionally, theta power decreased upon presentation of the item-specific cue, and this difference was related to later forgetting. Our results therefore disentangle, for the first time, interference and inhibition in episodic memory retrieval and suggest that theta oscillations track the fine-grained temporal dynamics of interference during competitive memory retrieval
