Incidental picture exposure affects later reading: evidence from the N400

Language comprehenders form a mental representation of the implied shape of objects mentioned in the text. In the present study, the influence of prior visual experience on subsequent reading was assessed. In two separate phases, participants saw a picture of an object and read a text about the object, suggesting the same or a different shape. When the shapes in the two phases mismatched, ERPs during reading showed a larger N400 amplitude than when the shapes matched, suggesting that a picture presented incidentally 15 min earlier affected reading. These results further strengthen the case for the interaction of language and visual experience during language comprehension.     

Facing the sunrise: cultural worldview underlying intrinsic-based encoding of absolute frames of reference in aymara

The Aymara of the Andes use absolute (cardinal) frames of reference for describing the relative position of ordinary objects. However, rather than encoding them in available absolute lexemes, they do it in lexemes that are intrinsic to the body: nayra (“front”) and qhipa (“back”), denoting east and west, respectively. Why? We use different but complementary ethnographic methods to investigate the nature of this encoding: (a) linguistic expressions and speech–gesture co‐production, (b) linguistic patterns in the distinct regional Spanish‐based variety Castellano Andino (CA), (c) metaphorical extensions of CA’s spatial patterns to temporal ones, and (d) layouts of traditional houses. Findings indicate that, following fundamental principles of Aymara cosmology, people, objects, and land—as a whole—are conceived as having an implicit canonical orientation facing east, a primary landmark determined by the sunrise. The above bodily based lexicalizations are thus linguistic manifestations of a broader macro‐cultural worldview and its psycho‐cognitive reality.     

Embodied simulation as part of affective evaluation processes: Task dependence of valence concordant EMG activity

The current studies investigated age-related biases in recall of emotion in older and younger adults. In two prospective–retrospective, Internet-based diary studies, older (aged 65 years and older) and younger participants (aged 18 to 37) reported on their affect at the end of every day. Participants then recalled their affect during the diary rating periods. In both studies, recall bias was assessed by comparing retrospective reports to the prospective diary ratings. Older adults tended to overestimate positive affect more than younger adults, who themselves tended to overestimate negative affect more than older adults, relative to diary ratings. Age-related patterns of recall bias are discussed in light of recent literature on the interface between cognition and emotion in ageing, particularly on increased positivity and reduced negativity effects in emotional processing and recall.     

Autonomy in Action: Linking the Act of Looking to Memory Formation in Infancy via Dynamic Neural Fields

Looking is a fundamental exploratory behavior by which infants acquire knowledge about the world. In theories of infant habituation, however, looking as an exploratory behavior has been deemphasized relative to the reliable nature with which looking indexes active cognitive processing. We present a new theory that connects looking to the dynamics of memory formation and formally implement this theory in a Dynamic Neural Field model that learns autonomously as it actively looks and looks away from a stimulus. We situate this model in a habituation task and illustrate the mechanisms by which looking, encoding, working memory formation, and long‐term memory formation give rise to habituation across multiple stimulus and task contexts. We also illustrate how the act of looking and the temporal dynamics of learning affect each other. Finally, we test a new hypothesis about the sources of developmental differences in looking.     

Effectiveness of a need supportive teaching training program on the developmental change process of graduate teaching assistants' created motivational climate

ObjectivesThere is a common trend to train physical education teachers and coaches in need supportive teaching behaviors, however, little research has been done with graduate teaching assistants (GTAs) in college and university physical activity programs. The purpose of this study was to test the effects of a need supportive teaching training program on GTAs' ability to promote need support in college and university physical activity courses.DesignLongitudinal and correlational.MethodParticipants were twelve GTAs from a midsized southeastern university in the United States, trained to deliver instruction in a positive motivational climate via in-person meetings, self-study materials, and tri-weekly meetings with researchers.ResultsMulti-level modeling revealed that the learning environment created by the GTAs improved across the duration of the study, with most of the growth between baseline and the first four intervention data points. Partial correlations seemed to indicate that these changes were influential among students, as evidenced through measurement of perceived autonomy support and motivational regulations.ConclusionsResults revealed that the behavioral change process was carried out quickly (from the beginning of the training), suddenly (rather than gradually), and then leveled off until the end of the semester. These results provide some promise in being able to effectively train GTAs to be need supportive in a relatively short amount of time.     

Pushing mom away: Embodied cognition and avoidant attachment

The objective of this research was to examine embodied psychological defense—the way in which defensive processes are manifest in basic motor responses. Forty-one participants were instructed to physically push or pull a lever in response to lexical stimuli presented on a computer display. Participants who were relatively avoidant with respect to attachment were faster to push the lever away from themselves when presented with the word “mom.” These results suggest that basic avoidant motives are automatically primed when attachment-related stimuli are processed, and that these tendencies manifest themselves in basic, motor-specific ways.     

A taste of words: linguistic context and perceptual simulation predict the modality of words

Previous studies have shown that object properties are processed faster when they follow properties from the same perceptual modality than properties from different modalities. These findings suggest that language activates sensorimotor processes, which, according to those studies, can only be explained by a modal account of cognition. The current paper shows how a statistical linguistic approach of word co-occurrences can also reliably predict the category of perceptual modality a word belongs to (auditory, olfactory-gustatory, visual-haptic), even though the statistical linguistic approach is less precise than the modal approach (auditory, gustatory, haptic, olfactory, visual). Moreover, the statistical linguistic approach is compared with the modal embodied approach in an experiment in which participants verify properties that share or shift modalities. Response times suggest that fast responses can best be explained by the linguistic account, whereas slower responses can best be explained by the embodied account. These results provide further evidence for the theory that conceptual processing is both linguistic and embodied, whereby less precise linguistic processes precede precise simulation processes.     

Modality switching costs emerge in concept creation as well as retrieval

Theories of embodied cognition hold that the conceptual system uses perceptual simulations for the purposes of representation. A strong prediction is that perceptual phenomena should emerge in conceptual processing, and, in support, previous research has shown that switching modalities from one trial to the next incurs a processing cost during conceptual tasks. However, to date, such research has been limited by its reliance on the retrieval of familiar concepts. We therefore examined concept creation by asking participants to interpret modality-specific compound phrases (i.e., conceptual combinations). Results show that modality switching costs emerge during the creation of new conceptual entities: People are slower to simulate a novel concept (e.g., auditory jingling onion) when their attention has already been engaged by a different modality in simulating a familiar concept (e.g., visual shiny penny). Furthermore, these costs cannot be accounted for by linguistic factors alone. Rather, our findings support the embodied view that concept creation, as well as retrieval, requires situated perceptual simulation.     

Arranging Objects in Space: Measuring Task‐Relevant Organizational Behaviors During Goal Pursuit

Human behavior unfolds primarily in built environments, where the arrangement of objects is a result of ongoing human decisions and actions, yet these organizational decisions have received limited experimental study. In two experiments, we introduce a novel paradigm designed to explore how individuals organize task‐relevant objects in space. Participants completed goals by locating and accessing sequences of objects in a computer‐based task, and they were free to rearrange the positions of objects at any time. We measure a variety of organization changes and evaluate how these measures relate to individual differences in performance. In Experiment 1, we show that with weak structure in task demands, changes in object positions that arise through performance of the task lead to improved order, characterized predominantly by a centralization of frequently used items and a peripheralization of infrequently used objects. In Experiment 2, with increased task structure, we observe more refined organizational tendencies, with selective contraction and clustering of interrelated task‐relevant objects. We further demonstrate that these more selective organization behaviors are reliably associated with individual differences in task performance. Collectively, these two studies reveal properties of space and of task demands that support and facilitate effective organization of the environment in support of ongoing behavior.     

The mirror reflects both ways: Action influences perception of others

Substantial evidence links perception of others’ bodies and mental representation of the observer’s own body; however, the overwhelming majority of this evidence is unidirectional, showing influence from perception to action. It has been proposed that the influence also runs from action to perception, but to date the evidence is scant. Here we report that ordinary motor actions performed by the subject affect concurrent psychophysical judgments of human-body stimuli. Subjects remained unaware of the connection between the action and the main task. The results show that perception can change as a result of the observer’s ongoing actions.
