“…To visualize similarities versus differences in enamel thickness topography, ad hoc imaging techniques were used to virtually unroll the lateral enamel and to project it into standardized morphometric maps (Bondioli et al, 2010, Macchiarelli et al, 2013, Zanolli et al, 2017. By using a custom developed routine in R v.3.4.0 (R Development Core Team, 2017) with the packages spatstat (Baddeley et al, 2015) and gstat (Pebesma, 2004), enamel thickness values were standardized between 0 and 1 and each morphometric map was set within a grid of 40 columns and 180 rows. For the two Javanese H. erectus specimens, five Neanderthal UM3s from Krapina (KRD97, KRD109, KRD162, KRD163, KRD170; NESPOS Database, 2017), and five recent humans (original data), we produced a consensus map generated by merging the available individual records into a single dataset and by subsequently calculating the interpolation using Generalized Additive Modeling (GAM; see Bondioli et al, 2010).…”

Locality 1, in the Lower Cave of the Zhoukoudian cave complex, China, is one of the most important Middle Pleistocene paleoanthropological and archaeological sites worldwide, with the remains of c. 45 Homo erectus individuals, 98 mammalian taxa, and thousands of lithic tools recovered. Most of the material collected before World War II was lost. However, besides two postcranial elements rediscovered in China in 1951, four human permanent teeth from the 'Dragon Bone Hill,' collected by O. Zdansky between 1921 and 1923, were at the time brought to the Paleontological Institute of Uppsala University, Sweden, where they are still stored. This small sample consists of an upper canine (PMU 25719), an upper third molar (PMU M3550), a lower third premolar crown (PMU M3549), and a lower fourth premolar (PMU M3887). Some researchers have noted the existence of morpho-dimensional differences between the Zhoukoudian and the H. erectus dental assemblage from Sangiran, Java. However, compared to its chrono-geographical distribution, the Early to Middle Pleistocene dental material currently forming the Chinese-Indonesian H. erectus hypodigm is quantitatively meager and still poorly characterized for the extent of its endostructural variation. We used micro-focus X-ray tomography techniques of virtual imaging coupled with geometric morphometrics for comparatively investigating the endostructural conformation (tissue proportions, enamel thickness distribution, enamel-dentine junction morphology, pulp cavity shape) of the four specimens stored in Uppsala, all previously reported for their outer features. The results suggest the existence of time-related differences between continental and insular Southeast Asian dental assemblages, the Middle Pleistocene Chinese teeth apparently retaining an inner signature closer to the likely primitive condition represented by the Early Pleistocene remains from Java, while the Indonesian stock evolved toward tooth structural simplification.

“…The available norms in Brazilian Portuguese allow researchers both to control and to manipulate specific word attributes, in different memory tasks, such as free recall and recognition. Another task commonly used in memory studies is cued recall, in which the experimenter provides cues to the participant at the time of testing (Baddeley et al, 2015). Tasks that use paired associates (e.g., foreign-native word pairs) fall into this category.…”

Normative studies are common in cognitive psychology because they allow us to estimate with more precision the attributes of the stimuli used in empirical studies. The studies reported here had four aims. The first three aims were to obtain estimates for (a) familiarity, concreteness, valence, and arousal for a single set of words in Brazilian Portuguese; (b) wordlikeness (similarity to Portuguese) of a set of foreign words (Swahili); and (c) recall accuracy of Swahili–Portuguese word pairs in a multitrial learning task. The fourth aim was to investigate if any of the assessed measures predicts recall accuracy. One-hundred twenty-eight participants took part in one of the three studies. In Studies 1a and 1b, participants judged 80 Portuguese words for familiarity, concreteness, valence, and arousal and 80 corresponding Swahili words for wordlikeness; in Study 2, participants carried out three study–test cycles of a set of Swahili–Portuguese word pairs. Overall, word-attribute estimates were reliable ( rs = .94–.98) and participants’ responses had high internal consistency (Cronbach’s α = .84–.98). Moreover, the relative difficulty of word pairs was retained across trials ( rs = .65–.88). Although different variables correlated with recall accuracy at different time points, multiple regressions indicate that none of the word-attribute variables predicted recall accuracy across trials. These norms may prove fruitful not only for Brazilian human memory researchers but also for international research teams, as it will enable the development of more controlled cross-cultural studies in this field.

“…Consider as an applied example the domain of numerical cognition. We found signatures of breathing-related processes on two widely used numerical tasks: random number generation is a standard method to examine or manipulate a person’s mental load (e.g., Baddeley et al 2015 ; Brugger 1997 ) while numerosity estimation is used to predict mathematical achievement (e.g., Halberda et al 2008 ; Schneider , 2017 ). Our results show that both tasks are influenced by interoceptive signals (i.e.…”

“BreaThink”: breathing affects production and perception of quantities

Cognition is shaped by signals from outside and within the body. Following recent evidence of interoceptive signals modulating higher-level cognition, we examined whether breathing changes the production and perception of quantities. In Experiment 1, 22 adults verbally produced on average larger random numbers after inhaling than after exhaling. In Experiment 2, 24 further adults estimated the numerosity of dot patterns that were briefly shown after either inhaling or exhaling. Again, we obtained on average larger responses following inhalation than exhalation. These converging results extend models of situated cognition according to which higher-level cognition is sensitive to transient interoceptive states.
