A processing advantage in favor of animate entities in incidental word learning in young children.

Because of their evolutionary importance, it has been proposed that animate entities would be better remembered than inanimate entities. Although a growing body of evidence supports this hypothesis, it is still unclear whether the animacy effect persists under incidental learning conditions. Furthermore, few studies have tested the robustness of this effect in young children, with conflicting results. Using an incidental learning paradigm, we investigated whether young children (4- and 5-year-olds) would be better at learning words that refer to either human or animal entities rather than vehicle entities using pictures as stimuli. A sample of 79 children were asked to play digital Memory games while associations between pictures and words were presented incidentally. Consistent with the adaptive view of memory, the results showed that words associated with human and animal entities were better learned incidentally than words associated with vehicle entities. The visual complexity of the pictures did not influence this animacy effect. In addition, the more exposure to the pictures, the more incidental learning occurred. Overall, the results confirm the robustness of the animacy effect and show that this processing advantage can be found in an incidental learning task in children as young as 4 or 5 years. Furthermore, it is the first study to show that this effect can be obtained with pictures in children. The demonstration of the animacy effect with pictures, and not just words, is a prerequisite for an ultimate explanation of this effect in terms of survival.

Does the Sensory Experience of Words Boost Recollection in Aging?

OBJECTIVES: We examine age-related differences in recollection and test the impact of words with high vs low sensory experience ratings (SER) in older and younger adults. We expected that the recollection of words with high SER would be similar in older and young adults, as they depend on knowledge, unlike recollection of words with a low SER, which would depend on executive functions. METHODS: We manipulated the sensory experience of words (high vs. low) in encoding in young and older adults. The participants then took a word-recognition test using the Remember/Know paradigm (Gardiner, 1988). We also evaluated executive functions using several measures. RESULTS: Results show that the age-related difference in recollective experience was eliminated under the high SER encoding condition. Moreover, Remember (R) responses in the low SER condition seem to be related to executive functioning, unlike R responses in the high SER condition and Know (K) responses in both low and high SER conditions. DISCUSSION: Our study shows that the memory benefit of high-SER words is greater for older than younger adults. The study also supports the observation that older adults can compensate for their deficits by using sensory experience to consciously recollect information.

Effect of Perceptions of Future Time on Implicit and Explicit Memory in Older Adults.

OBJECTIVES: We examine age-related differences in implicit and explicit memory tasks, and test the impact of future time perspectives on priming and cued recall. METHODS: We induced time perspective in young (limited-time perspective) and older (extended-time perspective) adults. Implicit and explicit memory tasks were performed by younger and older adults. RESULTS: Results showed an age-related effect on priming and cued recall, confirming that implicit and explicit memory are impaired in aging. Nevertheless, manipulation of future time perspective eliminated age differences in priming and cued recall. DISCUSSION: These findings support the view that it is not age per se that determines memory performance but rather the perception of the time left to us. Socio-emotional selectivity theory thus seems to be a serious candidate to explain age-related differences in implicit and explicit memory.

Psycholinguistic norms for a set of 506 French compound words.

Compounds are morphologically complex words made of different linguistic parts. They are very prevalent in a number of languages such as French. Different psycholinguistic characteristics of compounds have been used in certain studies to investigate the mechanisms involved in compound processing (see Table 7). We provide psycholinguistic norms for a set of 506 French compound words. The words were normed on seven characteristics: lexeme meaning dominance, semantic transparency, sensory experience, conceptual familiarity, imageability, age of acquisition (AoA) and subjective frequency. Reliability measures were computed for the collected norms. Descriptive statistical analyses, and correlational and multiple regression analyses were performed. We also report some comparisons made between our normative data and certain norms obtained in other similar studies. The entire set of norms, which will be very useful to researchers investigating the processing of compounds, is available as Supplemental Material.

Animacy effects in episodic memory: do imagery processes really play a role?

Animates are remembered better than inanimates because the former are ultimately more important for fitness than the latter. What, however, are the proximate mechanisms underpinning this effect? We focused on imagery processes as one proximate explanation. We tested whether animacy effects are related to the vividness of mental images (Study 1), or to the dynamic/motoric nature of mental images corresponding to animate words (Study 2). The findings showed that: (1) Animates are not estimated to be more vivid than inanimates; (2) The potentially more dynamic nature of the representations of animates does not seem to be a factor making animates more memorable than inanimates. We compared (Study 3) a condition in which participants had to categorise animate and inanimate words with a condition in which they had to form mental images from them. The animacy effect was significant after categorising but not after forming mental imagery. In Study 4, we compared the recall rates of animates and inanimates after these words had been encoded with or without a concurrent visual-spatial memory load. Again, animates were better remembered than inanimates. Taken overall, the findings do not fit well with the hypothesis that imagery processes support animacy effects in memory.

Which variables should be controlled for to investigate picture naming in adults? A Bayesian meta-analysis.

Selecting items for designing psycholinguistic experiments can be a very hard and time-consuming process, because of the large number of variables that need to be controlled for. This is clearly the case for picture-naming experiments because, thanks to the collection of psycholinguistic norms on both pictures and their names, a large number of factors that affect naming speed and/or accuracy have been found. In the present study, a Bayesian meta-analysis was performed to determine the extent to which the variables that have generally been considered by researchers as important to control for are indeed worth taking into account. The meta-analysis revealed that most of the variables that are considered in picture-naming studies have a strong or very strong influence on naming speed (image agreement, name agreement, image variability/imageability, age of acquisition, and conceptual familiarity), whereas two variables that are very often taken into account (visual complexity and length) yielded null effects. The results were inconclusive for lexical frequency. At a methodological level, Bayesian meta-analyses constitute a very useful tool for guiding researchers when selecting materials for experiments.

Concreteness norms for 1,659 French words: Relationships with other psycholinguistic variables and word recognition times.

Words that correspond to a potential sensory experience-concrete words-have long been found to possess a processing advantage over abstract words in various lexical tasks. We collected norms of concreteness for a set of 1,659 French words, together with other psycholinguistic norms that were not available for these words-context availability, emotional valence, and arousal-but which are important if we are to achieve a better understanding of the meaning of concreteness effects. We then investigated the relationships of concreteness with these newly collected variables, together with other psycholinguistic variables that were already available for this set of words (e.g., imageability, age of acquisition, and sensory experience ratings). Finally, thanks to the variety of psychological norms available for this set of words, we decided to test further the embodied account of concreteness effects in visual-word recognition, championed by Kousta, Vigliocco, Vinson, Andrews, and Del Campo (Journal of Experimental Psychology: General, 140, 14-34, 2011). Similarly, we investigated the influences of concreteness in three word recognition tasks-lexical decision, progressive demasking, and word naming-using a multiple regression approach, based on the reaction times available in Chronolex (Ferrand, Brysbaert, Keuleers, New, Bonin, Méot, Pallier, Frontiers in Psychology, 2; 306, 2011). The norms can be downloaded as supplementary material provided with this article.

MEGALEX: A megastudy of visual and auditory word recognition.

Using the megastudy approach, we report a new database (MEGALEX) of visual and auditory lexical decision times and accuracy rates for tens of thousands of words. We collected visual lexical decision data for 28,466 French words and the same number of pseudowords, and auditory lexical decision data for 17,876 French words and the same number of pseudowords (synthesized tokens were used for the auditory modality). This constitutes the first large-scale database for auditory lexical decision, and the first database to enable a direct comparison of word recognition in different modalities. Different regression analyses were conducted to illustrate potential ways to exploit this megastudy database. First, we compared the proportions of variance accounted for by five word frequency measures. Second, we conducted item-level regression analyses to examine the relative importance of the lexical variables influencing performance in the different modalities (visual and auditory). Finally, we compared the similarities and differences between the two modalities. All data are freely available on our website ( https://sedufau.shinyapps.io/megalex/ ) and are searchable at www.lexique.org , inside the Open Lexique search engine.

Are animacy effects in episodic memory independent of encoding instructions?

The adaptive view of human memory [Nairne, J. S. 2010. Adaptive memory: Evolutionary constraints on remembering. In B. H. Ross (Ed.), The psychology of learning and motivation (Vol. 53 pp. 1-32). Burlington: Academic Press; Nairne, J. S., & Pandeirada, J. N. S. 2010a. Adaptive memory: Ancestral priorities and the mnemonic value of survival processing. Cognitive Psychology, 61, 1-22, 2010b; Memory functions. In The Corsini encyclopedia of psychology and behavioral science, (Vol 3, 4th ed. pp. 977-979). Hokoben, NJ: John Wiley & Sons] assumes that animates (e.g., baby, rabbit presented as words or pictures) are better remembered than inanimates (e.g., bottle, mountain) because animates are more important for fitness than inanimates. In four studies, we investigated whether the animacy effect in episodic memory (i.e., the better remembering of animates over inanimates) is independent of encoding instructions. Using both a factorial (Studies 1 and 3) and a multiple regression approach (Study 2), three studies tested whether certain contexts drive people to attend to inanimate more than to animate things (or the reverse), and therefore lead to differential animacy effects. The findings showed that animacy effects on recall performance were observed in the grassland-survival scenario used by Nairne, Thompson, and Pandeirada (2007. Adaptive memory: Survival processing enhances retention. Journal of Experimental Psychology: Learning, Memory, & Cognition, 33, 263-273) (Studies 1-3), when words were rated for their pleasantness (Study 2), and in explicit learning (Study 3). In the non-survival scenario of moving to a foreign land (Studies 1-2), animacy effects on recall rates were not reliable in Study 1, but were significant in Study 2, whereas these effects were reliable in the non-survival scenario of planning a trip as a tour guide (Study 3). A final (control) study (Study 4) was conducted to test specifically whether animacy effects are related to the more organised nature of animates than inanimates. Overall, the findings suggest that animacy effects are robust since they do not vary across different sets of encoding instructions (e.g., encoding for survival, preparing a trip and pleasantness).

Do Healthy Elders, Like Young Adults, Remember Animates Better Than Inanimates? An Adaptive View.

Background/Study Context: It has been found that young adults remember animates better than inanimates. According to the adaptive view of human memory, this is due to the fact that animates are more important for fitness purposes than inanimates. This effect has been ascribed to episodic memory, where older people exhibit difficulties. METHODS: Here the authors investigated whether the animacy effect in memory also occurs for healthy older adults. Older and young adults categorized words for their animacy characteristics and were then given an unexpected recognition test on the words using the Remember/Know paradigm. Executive functions were also evaluated using several measures. RESULTS: For both overall Recognition and Remember responses, a reliable animacy effect on hit rates was found in young but not in older adults. Controlling for certain executive functions led to reliable and comparable animacy effects in both groups. There was no reliable effect of animacy on Know responses. CONCLUSION: Thus, unlike young adults, older adults do not remember animates better than inanimates; this pattern can be attributable to a decline in executive functions.

Does the thought of death contribute to the memory benefit of encoding with a survival scenario?

Four studies tested whether the thought of death contributes to the survival processing advantage found in memory tests (i.e., the survival effect). In the first study, we replicated the "Dying To Remember" (DTR) effect identified by Burns and colleagues whereby activation of death thoughts led to better retention than an aversive control situation. In Study 2, we compared an ancestral survival scenario, a modern survival scenario and a "life-after-death" scenario. The modern survival scenario and the dying scenario led to higher levels of recall than the ancestral scenario. In Study 3, we used a more salient death-thought scenario in which people imagine themselves on death row. Results showed that the "death-row" scenario yielded a level of recall similar to that of the ancestral survival condition. We also collected ratings of death-related thoughts (Studies 3 and 4) and of survival-related and planning thoughts (Study 4). The ratings indicated that death-related thoughts were induced more by the dying scenarios than by the survival scenarios, whereas the reverse was observed for both survival-related and planning thoughts. The findings are discussed in the light of two contrasting views of the influence of mortality salience in the survival effect.

Sensory experience ratings (SERs) for 1,659 French words: Relationships with other psycholinguistic variables and visual word recognition.

We collected sensory experience ratings (SERs) for 1,659 French words in adults. Sensory experience for words is a recently introduced variable that corresponds to the degree to which words elicit sensory and perceptual experiences (Juhasz & Yap Behavior Research Methods, 45, 160-168, 2013; Juhasz, Yap, Dicke, Taylor, & Gullick Quarterly Journal of Experimental Psychology, 64, 1683-1691, 2011). The relationships of the sensory experience norms with other psycholinguistic variables (e.g., imageability and age of acquisition) were analyzed. We also investigated the degree to which SER predicted performance in visual word recognition tasks (lexical decision, word naming, and progressive demasking). The analyses indicated that SER reliably predicted response times in lexical decision, but not in word naming or progressive demasking. The findings are discussed in relation to the status of SER, the role of semantic code activation in visual word recognition, and the embodied view of cognition.

Norms and reading times for acronyms in French.

We collected subjective frequency, age-of-acquisition, and imageability norms for 319 acronyms from French adults. Objective printed frequency, bigram frequency, and lengths in letters, phonemes, and syllables, as well as orthographic neighbors, were computed. The time taken to read acronyms aloud was also recorded. Correlational analyses indicated that the relations between the psycholinguistic variables were similar to those usually found for common words (e.g., highly imageable acronyms were more frequent and learned earlier in life than less imageable acronyms), but were generally weaker in the former than in the latter. Linear mixed-model analyses performed on the reading latencies revealed that the main determinants were the voicing feature of initial phonemes, the type of pronunciation of the acronyms (ambiguous vs. unambiguous, typical vs. atypical characteristics), length (number of letters and number of syllables), together with bigram frequency, printed frequency, and imageability. Both objective frequency and imageability interacted reliably with the ambiguous typical and ambiguous atypical properties. Accuracy was predicted by the number of letters and by imageability factors: More errors occurred on longer than on shorter acronyms, and also more errors on less imageable than on more imageable acronyms. The theoretical and methodological implications of the findings for the understanding of acronym reading are discussed. The entire set of norms and the acronym reading times (and accuracy scores), together with the acronym definitions, are provided as supplemental materials.

Animates are better remembered than inanimates: further evidence from word and picture stimuli.

In three experiments, we showed that animate entities are remembered better than inanimate entities. Experiment 1 revealed better recall for words denoting animate than inanimate items. Experiment 2 replicated this finding with the use of pictures. In Experiment 3, we found better recognition for animate than for inanimate words. Importantly, we also found a higher recall rate of "remember" than of "know" responses for animates, whereas the recall rates were similar for the two types of responses for inanimate items. This finding suggests that animacy enhances not only the quantity but also the quality of memory traces, through the recall of contextual details of previous experiences (i.e., episodic memory). Finally, in Experiment 4, we tested whether the animacy effect was due to animate items being richer in terms of sensory features than inanimate items. The findings provide further evidence for the functionalist view of memory championed by Nairne and coworkers (Nairne, 2010; Nairne & Pandeirada, Cognitive Psychology, 61 :1­22, 2010a, 2010b).

Norms and comprehension times for 305 French idiomatic expressions.

We report psycholinguistic norms for 305 French idiomatic expressions (Study 1). For each of the idiomatic expressions, the following variables are reported: knowledge, predictability, literality, compositionality, subjective and objective frequency, familiarity, age of acquisition (AoA), and length. In addition, we have collected comprehension times for each idiom (Study 2). The psycholinguistic relevance of the collected norms is explained, and different analyses (descriptive statistics, correlation and multiple regression analyses) performed on the norms are reported and discussed. The entire set of norms and reading times are provided as supplemental material.

Determinants of naming latencies, object comprehension times, and new norms for the Russian standardized set of the colorized version of the Snodgrass and Vanderwart pictures.

We report object-naming and object recognition times collected from Russian native speakers for the colorized version of the Snodgrass and Vanderwart (Journal of Experimental Psychology: Human Learning and Memory 6:174-215, 1980) pictures (Rossion & Pourtois, Perception 33:217-236, 2004). New norms for image variability, body-object interaction [BOI], and subjective frequency collected in Russian, as well as new name agreement scores for the colorized pictures in French, are also reported. In both object-naming and object comprehension times, the name agreement, image agreement, and age-of-acquisition variables made significant independent contributions. Objective word frequency was reliable in object-naming latencies only. The variables of image variability, BOI, and subjective frequency were not significant in either object naming or object comprehension. Finally, imageability was reliable in both tasks. The new norms and object-naming and object recognition times are provided as supplemental materials.

Do young children, like young adults, remember animates better than inanimates?

It has repeatedly been shown in adults that animates are remembered better than inanimates. According to the adaptive view of human memory this is due to the fact that animates are generally more important for survival than inanimates. Animacy enhances not only the quantity but also the quality of remembering. The effect is primarily driven by recollection. Virtually all studies have been conducted in adults, and we believe that the investigation of animacy effects in children is also highly relevant. The present study therefore tested the animacy effect on recollection in young (6-7 years, M = 6.6 years) and older children (10-12 years, M = 10.83 years) using the Remember/Know paradigm. As found in adults, an animacy effect on memory was found, but only in older children, and specifically in the "remember" responses, suggesting, once again, its episodic nature.

COVID-19 and Memory: A Novel Contamination Effect in Memory.

The Behavioral Immune System (BIS, Schaller & Park, 2011) is a defense system whose function is to protect against pathogen exposure. Memory is an important component of this system (Fernandes et al., 2017). We investigated "contamination effects" in memory in relation to COVID-19. Photographs of everyday objects were shown to adults (N = 80) in the hands of either a healthy or a contagious person who had contracted SARS-CoV-2. "Contaminated objects" were recalled better than "non-contaminated objects" suggesting that a contamination effect in memory in humans is easily acquired in the absence of apparent visual cues of disease.

Pseudo-Contamination and Memory: Is There a Memory Advantage for Objects Touched by "Morphologically Deviant People"?

Memory plays an important role in the behavioral immune system (BIS; Schaller in Psychological Inquiry, 17(2), 96-101, 2016a), a proactive immune system whose ultimate function is to make organisms avoid sources of contamination. Indeed, it has been found that objects presented next to sick people are remembered better than objects shown next to healthy people-representing a contamination effect in memory. In the present studies, we investigated this memory effect in relation to "pseudo-contaminated" sources, that is to say, people exhibiting cues ultimately evoking the threat of contamination but objectively posing no such threat in terms of disease transmission. Common objects were shown next to photographs of people having three kinds of morphological deviations-obesity (study 1), scars and burns (study 2), strange eyes (study 3)-or no morphological deviation. Contrary to our expectations, we found that "pseudo-contaminated objects" were not remembered better than "non-contaminated objects," whereas discomfort ratings of the idea of touching the same objects were clearly higher with morphologically deviant people. Memory mechanisms do not seem to be mobilized by "pseudo-contamination" sources which are not directly related to infection risk.

Russian norms for name agreement, image agreement for the colorized version of the Snodgrass and Vanderwart pictures and age of acquisition, conceptual familiarity, and imageability scores for modal object names.

The aim of the present study was to provide Russian normative data for the Snodgrass and Vanderwart (Behavior Research Methods, Instruments, & Computers, 28, 516-536, 1980) colorized pictures (Rossion & Pourtois, Perception, 33, 217-236, 2004). The pictures were standardized on name agreement, image agreement, conceptual familiarity, imageability, and age of acquisition. Objective word frequency and objective visual complexity measures are also provided for the most common names associated with the pictures. Comparative analyses between our results and the norms obtained in other, similar studies are reported. The Russian norms may be downloaded from the Psychonomic Society supplemental archive.
