- FACE-SENSITIVE EVENT-RELATED POTENTIALS: AGE-RELATED CHANGES, RACE EFFECT, CONTACT, AND IMPLICIT BIAS.
- Creator
- Molina, Karla Patricia Molina Valenzuela, Anzures, Gizelle, Florida Atlantic University, Department of Psychology, Charles E. Schmidt College of Science
- Abstract/Description

Early face-sensitive event-related potentials (ERPs) are modulated by age and race-of-face. Individual differences in implicit bias and race experience influence such race effects, but this remains largely unexplored. Thus, we examined children’s and adults’ P100s and N170s to own- and other-race faces and their relation with race experience and implicit racial bias. Children showed larger and more delayed P100s and N170s than adults. Also, 8- to 10-year-olds displayed earlier P100s to other...

Children showed larger and more delayed P100s and N170s than adults. Also, 8- to 10-year-olds displayed earlier P100s to other-race faces, while 5- to 7- year-olds showed earlier left N170s to own-race faces. In adults, greater own-race experience was associated with delayed left N170s to own-race faces. Greater own-race bias was associated with earlier right P100s to own-race faces in 5- to 7-year-olds and smaller left P100 to N170 peak-to-peak amplitudes to own-race faces in 8- to 10-yearolds. Individual differences in age, race experience, and implicit racial bias should be considered when examining ERPs to own- and other-race faces.

The mobile conjugate reinforcement (MCR) paradigm, made famous by Carolyn Rovee-Collier and her colleagues (Rovee & Rovee, 1969), has long been used to study infant learning and memory. In MCR studies, the infant's foot is tethered to a mobile hanging overhead, and the mobile responds directly to the infant's kicking.

Show moreThe mobile conjugate reinforcement (MCR) paradigm, made famous by Carolyn Rovee-Collier and her colleagues (Rovee & Rovee, 1969), has long been used to study infant learning and memory. In MCR studies, the infant's foot is tethered to a mobile hanging overhead, and the mobile responds directly to the infant's kicking. Infant kicking rate triples within a few minutes of interacting with the mobile. This result was classically interpreted as evidence of reinforcement learning. Kelso and Fuchs (2016) reinterpreted it as evidence that a coordinative structure, or functional synergy, forms between infant and mobile, triggering a positive feedback loop between the two. Positive feedback is proposed to give rise to an `Aha!' moment as the (prelinguistic) infant suddenly realizes it is an agent in control of the mobile's motion. While some have theorized the realization of self as causal agent emerges from organism-environment interactions, Kelso and Fuchs (2016) developed a mathematical model of the coordination dynamics between the infant and mobile, providing mechanistic explanations for the formation of agency. The current study was the first to measure movement of the mobile and analyze how dynamics of coordination between infant and mobile relate to possible transitions from spontaneous to intentional action. Novel measures of infant and mobile dynamics were used to test model predictions. Infant activity dropped drastically in response to non-contingent mobile movement and remained suppressed at the start of infant~mobile contingency, suggesting that mobile movement triggers a qualitatively different context for infants. This finding challenges the widely held assumption that mobile movement rewards and stimulates infant movement and calls into question the sufficiency of standard contingency detection cut-offs and explanations of conjugate reinforcement learning. Assessing coordination dynamics on a fine time scale using new analytical techniques made it possible to identify moments of agentive realization. Approaching agency as a relational phenomenon allowed for detailed characterization of the infant~mobile relationship and its role in the emergence of causal agency. In addition, the results revealed a number of surprising insights into agency formation such as the critical role of inactivity for agentive discovery and the possibility of intermediary stages or quasi-agentive states.

Objective: Our main objectives were to identify cognitive markers of progression to a more severe cognitive diagnosis, explore possible differences between ethnic groups and to correlate cognitive markers of progression with biomarkers of AD (hippocampal and entorhinal volumes) and frontal volumes (lateral orbitofrontal, medial orbitofrontal, superior frontal, and rostral middle frontal volumes).

Method: 207 participants (Mage = 71.79, SD = 7.48, 123 Hispanic Americans [HA]) were followed for an average of 23 months. Participants were classified into 3 diagnostic groups (Cognitively normal [CN], mild cognitive impairment [MCI], or dementia) based on the CDR global score and the neuropsychological baseline data was used as predictors of progression status. For the CN group, the Benson Figure delayed recall was a predictor of cognitive decline, and within the MCI group, the Benson delayed recall, the HVLT immediate recall, the TMTB, category fluency, and three measures of the LASSI-L (A1 cued recall, A2 cued recall, and delayed recall) were significant predictors of progression to dementia and are suggested as cognitive markers of progression for MCI individuals. Memory cognitive markers and category fluency correlated with medial temporal lobe volumes, and the TMT-B correlated with superior frontal volume. We did not observe significant differences in cognitive markers across ethnic groups. Conclusion: we identified cognitive markers of progression for CN and for MCI diagnoses which were not different across ethnic groups. These findings contribute to literature on the early identification of individuals at risk of progression to a more severe cognitive status even within asymptomatic individuals which can facilitate a more time- and cost-effective practice that is essential to the provision of the appropriate treatment to those at higher risk of progression.

Show moreTemperament and its development have been associated with the alpha band of EEG coherence in previous research that focused on adolescent and adult populations, results suggest that this measure stands as a reliable indicator of emotional states. In the current study, five data sets from previously conducted studies were analyzed to determine if resting state alpha coherence measures differ in various brain regions and are associated with variation in levels of temperament. Additionally, we aimed to determine if, as age increases, a synchronous result in coherence may be seen (specifically, from posterior to anterior), in accordance with neurophysiological development. Regression analyses suggested that the negative affectivity temperamental qualities did not significantly associate with coherence. Repeated-measures analyses yielded significant results in favor of the electrocortical development hypothesis and, through exploratory analysis, more reactive temperament scores depicting positive affectivity, emotional/self-regulation, and activity level displayed in infants who had higher coherence in posterior regions. The study was suggestive of high coherence values associating with highly reactive temperamental attributes in posterior regions in the 3- to 12-month-old participants and higher coherence values displaying in posterior regions compared to anterior regions consistently across age groups.

Show moreWhen viewing advertisements, one could be exposed to new information about the product. During that time, one could construct ad hoc categories or simple attributes for the brand-name product. The current experiment used functional near-infrared spectroscopy (fNIRS) to measure bilateral frontal and temporal cortices to understand the contribution of constructing ad hoc categories and simple attributes on purchase intentions. The current experiment also examined the feasibility of using the tensor decomposition method compared to the grand averaging method in multidimensional fNIRS signal analysis. This is to see if tensor decomposition can maintain the pattern of hemodynamic response without losing the temporal dynamics and spatial array to find a more optimized time and regions of interest to average across. The current experiments consisted of two parts: 1) participants studied brand-name products for various ad hoc categories (Experiment 1) or various simple attributes (Experiment 2) and 2) pick for purchase brand-name products in a two-alternative forced choice purchase intention test. Three methods were used to analyze the hemodynamic response data: the grand averaging method, the tensor decomposition method, and the revised grand averaging method. The revised grand averaging method is the same as the grand averaging method but uses information from the tensor decomposition method to inform what time and channel to average across. There were behavioral priming benefits compared to products that were not studied. However, there were no differences across the study conditions. Results revealed processing benefits, not purchasing benefits, for brand-name products studied for different simple attributes as marked by changes in the left prefrontal cortex. The results from tensor decomposition revealed more details on the time and channels of interest than the grand averaging method. Findings suggest that studying different simple attributes of a brand-name product produces benefits in the purchase intention process. Also, findings suggest tensor decomposition is a feasible method for fNIRS signal analysis.

However, individual differences in newly validated identity orientations (i.e., the preference to expand or conserve one’s sense of self; Hughes et al., 2020) may influence identity recovery. The current studies examined the influence of self-expansion preference on self-concept clarity and identity restoration mechanisms (i.e., relationship rekindling) following relationship dissolution using cross sectional (Study 1), intensive longitudinal (Study 2), and dynamical (Study 3) methods. Across studies, self-expansion preference emerged as a trait-level predictor of post-breakup experiences including self-concept clarity, distress, and relationship rekindling desire. Implications for individual experiences of romantic relationship dissolution are discussed.

Show moreThe field of evolutionary developmental psychology can potentially broaden the horizons of mainstream evolutionary psychology by combining the principles of Darwinian evolution by natural selection with the study of human development, focusing on the epigenetic effects that occur between humans and their environment in a way that attempts to explain how evolved psychological mechanisms become expressed in the phenotypes of adults. An evolutionary developmental perspective includes an appreciation of comparative research and we, among others, argue that contrasting the cognition of humans with that of nonhuman primates can provide a framework with which to understand how human cognitive abilities and intelligence evolved. Furthermore, we argue that several «immature» aspects of childhood (e.g., play and immature cognition) serve both as deferred adaptations as well as imparting immediate benefits. Intense selection pressure was surely exerted on childhood over human evolutionary history and, as a result, neglecting to consider the early developmental period of children when studying their later adulthood produces an incomplete picture of the evolved adaptations expressed through human behavior and cognition.

Show moreChromatic induction compellingly demonstrates that chromatic context as well as spectral lights reflected from an object determines its color appearance. Here, we show that when one colored object moves around an identical stationary object, the perceived saturation of the stationary object decreases dramatically whereas the saturation of the moving object increases. These color appearance shifts in the opposite directions suggest that normalization induced by the object’s motion may mediate the shift in color appearance. We ruled out other plausible alternatives such as local adaptation, attention, and transient neural responses that could explain the color shift without assuming interaction between color and motion processing. These results demonstrate that the motion of an object affects both its own color appearance and the color appearance of a nearby object, suggesting a tight coupling between color and motion processing.

The sample was divided in two age groups: G1, age 5 to 8 years and G2, age 9 to 16 years. Attention and memory sub-tests from the Evaluación Neuropsicológica Infantil-ENI (Matute, Rosselli, Ardila and Ostrosky, 2007) were analyzed. There was a significant effect of age on all sub-tests scores where older children obtained higher scores. Also, there was a significant effect of sex and type of school in some tasks, where girls had higher performance than boys and, the students of PrS scored higher than students of PuS. An interaction between type of school and sex was also evident: PrS girls showed higher performance than other groups in some tasks of attention and memory, especially those that imply verbal information processing. There was a significant correlation between the parents’educational level and the performance in G2. Sons of parents with high educational level show better performance than sons of parents with low educational level. The results are discussed in terms of the environmental variables effect on the development of attention and memory.
