Dissociating Simon and affordance compatibility effects: Silhouettes and photographs

When a graspable object’s handle is oriented to the same side as the response hand, responses are quicker and more accurate than when it is oriented to the opposite side. This effect has been attributed to the affordance of the object’s handle (Tucker & Ellis, 1998). Recent findings suggest this effect results instead from an abstract spatial response code (i.e., Simon effect; Cho & Proctor, 2010). However, the stimuli used in these previous studies differ in the amount of object and environmental depth information they contain, which may be critical to conveying an affordance. This information could explain these disparate findings as well as dissociate Simon and affordance compatibility effects. Four experiments demonstrate that the Simon effect results from the absence of this information, as in a silhouette, and the affordance effect results from its presence, as in a photograph. A fifth experiment confirmed that modifying information associated with the affordance, rather than the modification itself, produced the effects observed in the previous experiments. These findings support the following: (a) the internal details of an object and environmental depth can dissociate Simon and affordance compatibility effects, (b) this information is necessary to convey the object’s graspable affordance, and (c) the outer shape of the object is not sufficient to elicit an affordance effect. These findings are discussed in relation to the theory of embodied cognition.     

In touch with numbers: Embodied and situated effects in number magnitude comparison

The idea of embodied numerosity denotes that seemingly abstract number concepts (e.g., magnitude) are rooted in bodily experiences and situated action. In the present study we evaluated whether there is an embodied representation of the place–value structure of the Arabic number system and if so whether this representation is influenced by situated aspects. In a two-digit number magnitude comparison task participants had to directly touch the larger of two numbers. Importantly, pointing responses were systematically biased toward the decade digit of the target number. Additionally, this leftward bias towards the tens digit was reduced in unit–decade incompatible number pairs. Thereby, we demonstrated an influence of place–value processing on manual pointing movement. Our results therefore corroborate the notion of an embodied representation of the place–value structure of Arabic numbers which is modulated by situated aspects.     

Toward an Ethical Reflective Practice of a Theory in the Flesh: Embodied Subjectivities in a Youth Participatory Action Research Mural Project

The focus of this paper is to demonstrate how embodied subjectivities shape research experiences. Through an autoethnography of my involvement in a Youth Participatory Action Research (YPAR) after‐school program with low‐income and working‐class youth of Color from predominantly Latinx communities I examined my embodied subjectivities, via an ethical reflective practice, as these surfaced in the research context. Autoethnography is presented as a tool to facilitate an ethical reflective practice that aligns with heart‐centered work. Drawing from an epistemology of a theory in the flesh (Anzaldúa & Moraga, 1981), embodied subjectivities are defined by the lived experiences felt and expressed through the body, identities, and positionalities of the researcher. The article concludes with implications for the development of community psychology competencies that attend to the researcher's embodied subjectivities.     

An effect of mood on the perception of geographical slant

Previous research has shown that hills appear steeper to those who are fatigued, encumbered, of low physical fitness, elderly, or in declining health (Bhalla & Proffitt, 1999; Proffitt, Bhalla, Gossweiler, & Midgett, 1995). The prevailing interpretation of this research is that observers’ perceptions of the environment are influenced by their capacity to navigate that environment. The current studies extend this programme by investigating more subtle embodied effects on perception of slant; namely those of mood. In two studies, with two different mood manipulations, and two estimates of slant in each, observers in a sad mood reported hills to be steeper. These results support the role of mood and motivational factors in influencing spatial perception, adding to the previous work showing that energetic potential can influence perception.     

Understanding action language modulates oscillatory mu and beta rhythms in the same way as observing actions

The mu rhythms (8–13 Hz) and the beta rhythms (15 up to 30 Hz) of the EEG are observed in the central electrodes (C3, Cz and C4) in resting states, and become suppressed when participants perform a manual action or when they observe another’s action. This has led researchers to consider that these rhythms are electrophysiological markers of the motor neuron activity in humans. This study tested whether the comprehension of action language, unlike abstract language, modulates mu and low beta rhythms (15–20 Hz) in a similar way as the observation of real actions. The log-ratios were calculated for each oscillatory band between each condition and baseline resting periods. The results indicated that both action language and action videos caused mu and beta suppression (negative log-ratios), whereas abstract language did not, confirming the hypothesis that understanding action language activates motor networks in the brain. In other words, the resonance of motor areas associated with action language is compatible with the embodiment approach to linguistic meaning.     

Setting the bar for cognitive agency: Or,how minimally autonomous can an autonomous agent be?

Embodied cognition comes in many variants. Yet, in most if not all of these variants the notion of agency, or more precisely autonomous agency, occupies center stage. However, whereas in its original context of application autonomy applies strictly to the human sphere, cognitive theory must needs generalize this concept so as to render it applicable to a much wider range of entities and processes. Theorists of embodied cognition must therefore strive to articulate a valid sense of minimal autonomy applicable to animals and, arguably, to artificial agents as well. In this paper I discuss two major attempts to articulate a conception of minimal autonomy which I describe, respectively, as the adaptive-behavior approach (ABA) and the systemic-constructivist approach (SCA). The differences between these two leading views on minimal autonomy reveal fundamental disagreements not only with respect to the nature of autonomous agency but also with respect to embodiment and the relevance of biological life to the making of mental life.     

Embodied metaphor and the “true” self: Priming entity expansion and protection influences intrinsic self-expressions in self-perceptions and interpersonal behavior

Drawing on conceptual metaphor perspectives and embodied cognition theories, we proposed that the intrinsic self-concept-who people think they truly are-is represented metaphorically as a physical entity, and that expressions of the intrinsic self-concept are therefore conceptualized in terms of entity activity. Using an empirical strategy for experimentally investigating conceptual metaphor, we tested whether exposure to pictorial primes depicting entity expansion and protection produces metaphor-consistent effects on self-perceptions and interpersonal behaviors expressive of the intrinsic self-concept. In Study 1, participants primed with entity expansion perceived themselves as more self-actualized and less concerned with satisfying extrinsic contingencies of self-esteem. Study 2 showed that this effect was mediated by the increased accessibility of the concept entity expansion. In Study 3, expansion-primed participants conformed less to other people's opinions. In Study 4, participants primed with entity protection were less willing to disclose intimate, but not non-intimate, self-knowledge to a stranger.     

Are sensorimotor experiences the key for successful early intervention in infants with congenital brain lesion?

Living with a congenital brain lesion may have detrimental effects on the ability to do everyday activities, but contrary to acquired brain lesions, people and in particular children, with congenital brain lesions may have limited or no experience of how their bodies work. This absence of experience gives rise to challenges for habilitation of sensorimotor abilities and derived cognitive abilities. How can motor and cognitive abilities be achieved and trained in an individual with no experience of potential abilities? In this article, we aim to review the existing knowledge about the development of sensorimotor integration. Further, we will discuss this knowledge in the light of two neurocognitive theories: embodied cognition and predictive coding. Moreover, using developmental knowledge and theory in combination, we will argue that early sensorimotor development serves as a foundation for later cognitive development. Finally, we try to use these elements in a strategy to make interventions as early as possible, with the purpose of improving sensorimotor and cognitive abilities in children with congenital brain lesions.     

Moving arms: the effects of sensorimotor information on the problem-solving process

Embodied cognition postulates a bi-directional link between the human body and its cognitive functions. Whether this holds for higher cognitive functions such as problem solving is unknown. We predicted that arm movement manipulations performed by the participants could affect the problem-solving solutions. We tested this prediction in quantitative reasoning tasks that allowed two solutions to each problem (addition or subtraction). In two studies with healthy adults (N?=?53 and N?=?50), we found an effect of problem-congruent movements on problem solutions. Consistent with embodied cognition, sensorimotor information gained via right or left arm movements affects the solution in different types of problem-solving tasks.
