However, there is a lack of behavioral evidence in support of this proposal. The aim of the present work was to test whether words' degree of social relevance, or <i>socialness</i>, influences lexical-semantic processing. In Study 1, across a series of item-level regression analyses, we found that (a) socialness can facilitate responses in lexical, semantic, and memory tasks, and (b) limited evidence for an interaction of socialness with concreteness. In Studies 2-3, we tested the preregistered hypothesis that social words, compared to nonsocial words, will be associated with faster and more accurate responses during a syntactic classification task. We found that socialness has a facilitatory effect on noun decisions (Study 3), but not verb decisions (Study 2). Overall, our results suggest that the socialness of a word affects lexical-semantic processing but also that this is task-dependent. These findings constitute novel evidence in support of proposals that social information is an important dimension of semantic representation.

Importantly, the categories we use to structure the world are informed by the language we speak. For example, whether we perceive dark blue, light blue, and green to be shades of one, two, or three different colors depends on whether we speak Berinmo, English, or Russian, respectively. Different languages, then, differ by how granular their categories are, but the source of these differences is still poorly understood. Understanding the source of cross-linguistic differences in linguistic categorization is important because categorization influences communicative efficiency and cognitive performance. Here we use computational simulations to show that community structure and specifically community size and community interconnectivity influence the categorization systems that communities create. In particular, the simulations show that the obstacles for diffusion that large communities encounter push them to develop categorization systems that are more expressive and better understood, but only if they have sufficiently long memory to do so. The simulations also show that larger communities are better at creating useful references to rarely communicated meanings, thus further boosting communication in these cases. These findings demonstrate how taking social structure, and especially community size, into account can illuminate why languages evolved to have their current forms. They further show how social constraints, such as those encountered by large communities, can drive the creation of better and more robust systems. As categorization is a building block for many cultural products, these results also have implications for our understanding of cultural evolution more broadly.

This temporal fluctuation has downstream effects on memory for stimuli presented during the task. Researchers have established that detection of a target (e.g., a square of a color to which participants are instructed to respond with a button press) within a rapid serial visual presentation (RSVP) stream leads to better memory for concurrently presented stimuli than for stimuli presented along with an RSVP distractor (e.g., a square of a color to which participants are instructed to withhold response). Although debates have arisen regarding whether this memory difference, termed the attentional boost effect, results from target-induced enhancement, distractor-induced impairment, or a combination of the two, researchers have largely come to focus on explanations that consider only target-induced memory enhancement. In the present study, we show across three large-sampled experiments a consistent appearance of both target-induced memory enhancement and distractor-induced memory impairment relative to a baseline. In each experiment, participants responded with a spacebar press to squares of one color in an RSVP stream while withholding response to squares of another color and trials with no square (baseline trials). They simultaneously memorized concurrently presented objects. The presence of both enhancement and impairment in these experiments invites the development of new dual-task research that considers distractor-induced memory impairment and the control of temporal selection across tasks.

Experimental results from toddlers suggest phonological specificity. By contrast, the featurally underspecified lexicon theory (Lahiri, 2018; Lahiri & Reetz, 2010), motivated by evidence such as the cross-linguistic prevalence of phenomena such as coronal assimilation (rainbow → rai[m]bow), proposes that coronal sounds are unspecified for place of articulation even in the adult lexicon. The featurally underspecified lexicon, therefore, predicts that asymmetries in mispronunciation sensitivity are also present in the developing lexicon. Recent research (Ren et al., 2019) has rejected this, reporting similar sensitivity to mispronunciation of coronals and noncoronals at 19 months. Using a more sensitive experimental paradigm, we provide new evidence demonstrating a lack of asymmetries at 18 months, but mispronunciation sensitivity for coronals disappears by 24 months. In an intermodal preferential looking study, growth curve analysis shows that 18-month-olds are sensitive to mispronunciations of words with a coronal (e.g., <i>duck</i> vs. <i>*buck</i>) and noncoronal (e.g., <i>bird</i> vs<i>. *dird</i>) onset. At 24 months, mispronunciations of coronal-onset words were treated just like the accurate pronunciations. We conclude that coronals are underspecified in the developing lexicon at 24 months. We propose a model under which initial representations are phonetic in nature and require exact acoustic input, whereas phonological coronal underspecification at the lexical level emerges gradually as a result of exposure to variation in the input such as coronal assimilations that only become detectable patterns with growing lexical and segmentation skills.

They had to sight read both tonal classical scores that followed the rules specific to Western tonal music, and atonal contemporary scores, which do not follow these rules. This study aimed at determining the extent to which eye movements and musical performance metrics can account for the level of sight-reading expertise. First, the results indicated that with the acquisition of expertise, musicians process visual information more rapidly (increasing their played tempo while decreasing average fixation duration and their number of fixations), more structurally (tending to increase their eye-hand span), and more accurately (increasing their sight-reading accuracy). Second, when they sight read contemporary scores compared to classical scores, musicians decreased their played tempo, tended to be less accurate, increased their number of fixations, and tended to decrease their eye-hand span. Finally, expertise effects were moderated by the type of score. These results suggest (a) that visual perception is progressively shaped through music reading expertise and through domain-specific knowledge acquisition, (b) that tonal-specific cues play a significant role to use an efficient eye-movement behavior and (c) that the benefit conferred by expert prior music-specific knowledge seems to be even greater for sight-reading tonal rather than atonal scores.

However, a combination of publication bias and small sample sizes (∼<i>N</i> = 25) hampers certainty in current effect size estimates. We sought to determine the extent to which sample sizes may produce errors in effect size estimates for four commonly used paradigms assessing attention, executive function, and implicit learning (attentional blink, multitasking, contextual cueing, and serial response task). We combined a large data set with a bootstrapping approach to simulate 1,000 experiments across a range of N (13-313). Beyond quantifying the effect size and statistical power that can be anticipated for each study design, we demonstrate that experiments with lower N may double or triple information loss. We also show that basing power calculations on effect sizes from similar studies yields a problematically imprecise estimate between 40% and 67% of the time, given commonly used sample sizes. Last, we show that skewness of intersubject behavioral effects may serve as a predictor of an erroneous estimate. We conclude with practical recommendations for researchers and demonstrate how our simulation approach can yield theoretical insights that are not readily achieved by other methods such as identifying the information gained from rejecting the null hypothesis and quantifying the contribution of individual variation to error in effect size estimates.
