Towards a More Precise Conceptualization of Empathy: An Integrative Review of Literature on Definitions, Associated Functions, and Developmental Trajectories

Empathy entails basic cognitive processes such as the recognition of facial expressions and basic emotional processes such as emotional contagion, but also higher-order cognitive processes such as abstract reasoning about the other person’s emotional states and higher-order emotional processes such as empathic concern. Thus, empathy must be conceptualized as a multidimensional and multifaceted construct. It can be differentiated from related constructs such as theory of mind, emotional contagion, compassion, emotional mimicry, or perspective-taking by its associated processes and functions. To understand the nature of empathy, it is important to combine phylogenetic, ontogenetic, neuroscientific, dynamic-interactionist, and sociological perspectives on this phenomenon.

The development of real-time stability supports visual working memory performance: Young children's feature binding can be improved through perceptual structure.

Working memory is a basic cognitive process that predicts higher-level skills. A central question in theories of working memory development is the generality of the mechanisms proposed to explain improvements in performance. Prior theories have been closely tied to particular tasks and/or age groups, limiting their generalizability. The cognitive dynamics theory of visual working memory development has been proposed to overcome this limitation. From this perspective, developmental improvements arise through the coordination of cognitive processes to meet demands of different behavioral tasks. This notion is described as real-time stability, and can be probed through experiments that assess how changing task demands impact children's performance. The current studies test this account by probing visual working memory for colors and shapes in a change detection task that compares detection of changes to new features versus swaps in color-shape binding. In Experiment 1, 3- to 4-year-old children showed impairments specific to binding swaps, as predicted by decreased real-time stability early in development; 5- to 6-year-old children showed a slight advantage on binding swaps, but 7- to 8-year-old children and adults showed no difference across trial types. Experiment 2 tested the proposed explanation of young children's binding impairment through added perceptual structure, which supported the stability and precision of feature localization in memory-a process key to detecting binding swaps. This additional structure improved young children's binding swap detection, but not new-feature detection or adults' performance. These results provide further evidence for the cognitive dynamics and real-time stability explanation of visual working memory development. (PsycINFO Database Record

Contentless basic minds and perceptual knowledge

Assuming a radical stance on embodied cognition, according to which the information acquired through basic cognitive processes is not contentful (Hutto and Myin, 2013), and assuming that perception is a source of rationally grounded knowledge (Pritchard, 2012), a pluralistic account of perceptual knowledge is developed. The paper explains: (i) how the varieties of perceptual knowledge fall under the same broader category; (ii) how they are subject to the same kind of normative constraints; (iii) why there could not be a conflict between the different varieties of perceptual knowledge; and (iv) why the traditional epistemological inquiry is inclined to overestimate the role of propositional perceptual knowledge. Keywords: Radical enactivism, perceptual knowledge, knowledge-how, knowledge-that.

Social cognition in neuropsychiatric populations: a comparison of theory of mind in schizophrenia and mesial temporal lobe epilepsy

Social cognition deficits are observed both in patients with schizophrenia (SCZ) and in patients with mesial temporal lobe epilepsy (MTLE). This may be due to dysfunction of the amygdala network, which is a common feature of both diseases. In this study, SCZ (n = 48) or MTLE (n = 31) and healthy controls (HC, n = 47) completed assessments of mentalising (Reading Mind in the Eyes Test, RMET) and basic cognitive processing, e.g., working memory, executive functions and psychomotor speed (Trail-Making Test B and Digit Symbol). SCZ were also assessed with the Positive And Negative Syndrome Scale (PANSS). We found that the RMET scores of the two clinical groups were similar (p > 0.05) and lower than in the HCs (SCZ: p < 0.05; MTLE: p < 0.001). In the next step, SCZ were split into two groups with respect to the level of symptoms. Analysis of the RMET scores revealed no differences between the HC (M = 25.7 ± 4.1) and POS-LO (M = 25.3 ± 4.8); both groups outperformed the POS-HI group (M = 21.3 ± 5.2) and the MTLE group (M = 20.8 ± 4.6). No differences were found for the median-split with regard to negative symptoms. In SCZ, the mind-reading deficit appears to be associated with the level of positive symptoms. Both POS-HI and MTLE patients present significant mentalising deficits compared to healthy controls.

Using Video Game Telemetry Data to Research Motor Chunking, Action Latencies, and Complex Cognitive-Motor Skill Learning.

Many theories of complex cognitive-motor skill learning are built on the notion that basic cognitive processes group actions into easy-to-perform sequences. The present work examines predictions derived from laboratory-based studies of motor chunking and motor preparation using data collected from the real-time strategy video game StarCraft 2. We examined 996,163 action sequences in the telemetry data of 3,317 players across seven levels of skill. As predicted, the latency to the first action (thought to be the beginning of a chunked sequence) is delayed relative to the other actions in the group. Other predictions, inspired by the memory drum theory of Henry and Rogers, received only weak support.

Behavioral activation treatment for major depression: A randomized trial of the efficacy of augmentation with cognitive control training

BackgroundMajor depressive disorder (MDD) is associated with hypoactivation of the dorsolateral prefrontal cortex, a brain region involved in emotion regulation and basic cognitive control processes. Recent studies have indicated that computerized interventions designed to activate this region may reduce depressive and ruminative symptoms. In this double-blind randomized controlled trial, we tested whether one such program, called Cognitive Control Training (CCT), enhanced treatment outcomes when used in adjunct to brief behavior therapy for MDD. MethodsThirty-four adults with MDD were randomly assigned to complete four sessions of either computerized CCT or a control task, concurrently with four sessions of Brief Behavioral Activation Therapy for Depression (BATD). Post-treatment and one-month follow-up assessments were conducted, with self-reported depressive symptoms as the primary outcome and clinician-rated depressive symptoms and self-reported rumination as secondary outcomes. ResultsIn both intent-to-treat and completer analyses, depressive symptoms and rumination decreased significantly over the course of treatment in both treatment conditions. There were no significant differences in treatment outcome depending on the augmentation condition. LimitationsThe sample size was small, hindering secondary analyses and identification of potential predictors or moderators of treatment effect. ConclusionsResults demonstrate substantial clinical benefit following four sessions of BATD; however, adjunctive CCT did not enhance outcomes. This study and other recent research suggest that the effects of CCT may not be as robust as previously indicated, highlighting the need for continued investigation of the conditions under which CCT may be effective.

The Proposal of Investigating the Possible Extraversion Effect in the Neurofeedback

Optimal cognitive functioning is an essential prerequisite of an effective learning. However, during the learning process, in addition to basic cognitive processes and abilities and from the perspective of intrapersonal factors, the personality of the learner significantly influences on his/her learning outcomes. Prior psychological research demonstrated significant differences in teaching methods and learning outcomes between people who have high and low levels of extraversion. This moderating effect of personality is especially visible in certain learning models, such as the operant conditioning. Taking into account the biological basis of cognition and personality, the question is whether it is possible that different personality traits have the effect on the operant conditioning of brainwaves (neurofeedback)? In other words, is it possible to explain the various neurofeedback training results by the moderation effect of personality traits, especially extraversion? Moreover, some critical validation studies have indicated that extraversion might be the cause of various findings on the effectiveness of neurofeedback, since it has not been controlled in these studies. Therefore, the main focus of this review is to present the research proposal for studying the possible extraversion effect in neurofeedback.

Selective reaching in macaques: evidence for action-centred attention.

When a monkey selects a piece of food lying on the ground from among other viable objects in the near vicinity, only the desired item governs the particular pattern and direction of the animal's reaching action. It would seem then that selection is an important component controlling the animal's action. But, we may ask, is the selection process in such cases impervious to the presence of other objects that could constitute potential obstacles to or constraints on movement execution? And if it is, in fact, pervious to other objects, do they have a direct influence on the organization of the response? The kinematics of macaques' reaching movements were examined by the current study that analysed some exemplars as they selectively reached to grasp a food item in the absence as well as in the presence of potential obstacles (i.e., stones) that could affect the arm trajectory. Changes in movement parameterization were noted in temporal measures, such as movement time, as well as in spatial ones, such as paths of trajectory. Generally speaking, the presence of stones in the vicinity of the acting hand stalled the reaching movement and affected the arm trajectory as the hand veered away from the stone even when it was not a physical obstacle. We concluded that nearby objects evoke a motor response in macaques, and the attentional mechanisms that allow for a successful action selection are revealed in the reaching path. The data outlined here concur with human studies indicating that potential obstacles are internally represented, a finding implying basic cognitive operations allowing for action selection in macaques.

Executive Control of Actions Across Time and Space

Many popular psychological accounts attribute adaptive human behavior to an “executive-control” system that regulates a lower-level “impulsive” or “associative” system. However, recent findings argue against this strictly hierarchical view. Instead, executive control of impulsive and inappropriate actions depends on an interplay between multiple basic cognitive processes. The outcome of these processes can be biased in advance. Executive-action control is also strongly influenced by personal experiences in the recent and distant past. Thus, executive control emerges from an interactive and competitive network. Main challenges for future research are to describe and understand these interactions and to put executive-action control in a wider sociocultural and evolutional context.

Neural correlates of response inhibition in current and former smokers

Loss of behavioral control is a hallmark of addiction. Individual differences in basic cognitive processes such as response inhibition may be important for interrupting automatic behaviors associated with smoking and supporting prolonged abstinence. To examine how response inhibition and error monitoring processes differ as a function of smoking status, current smokers, former smokers and never smokers (N=126) completed a simple Go/No-Go task while undergoing functional magnetic resonance imaging. All groups performed similarly on the task and similarly engaged the inferior frontal gyrus and dorsal anterior cingulate cortex, regions traditionally associated with response inhibition and error monitoring, respectively. During response inhibition (i.e., Correct Rejects>Hits contrast), overall group differences emerged in the recruitment of the cerebellum, while individual group differences in error monitoring (False Alarms>Hits contrast) were seen for regions of the parietal lobe and thalamus (current smokers>former smokers), as well as regions of the bilateral cerebellum, parahippocampal gyrus and superior parietal lobe (i.e., ever smokers>never smokers). We discuss how our results replicate two previous large-sample studies that used the same Go/No-Go task and review these data in terms of network models of inhibitory and error monitoring abnormalities in addiction.

Strong genetic overlap between executive functions and intelligence.

Executive functions (EFs) are cognitive processes that control, monitor, and coordinate more basic cognitive processes. EFs play instrumental roles in models of complex reasoning, learning, and decision making, and individual differences in EFs have been consistently linked with individual differences in intelligence. By middle childhood, genetic factors account for a moderate proportion of the variance in intelligence, and these effects increase in magnitude through adolescence. Genetic influences on EFs are very high, even in middle childhood, but the extent to which these genetic influences overlap with those on intelligence is unclear. We examined genetic and environmental overlap between EFs and intelligence in a racially and socioeconomically diverse sample of 811 twins ages 7 to 15 years (M = 10.91, SD = 1.74) from the Texas Twin Project. A general EF factor representing variance common to inhibition, switching, working memory, and updating domains accounted for substantial proportions of variance in intelligence, primarily via a genetic pathway. General EF continued to have a strong, genetically mediated association with intelligence even after controlling for processing speed. Residual variation in general intelligence was influenced only by shared and nonshared environmental factors, and there remained no genetic variance in general intelligence that was unique of EF. Genetic variance independent of EF did remain, however, in a more specific perceptual reasoning ability. These results provide evidence that genetic influences on general intelligence are highly overlapping with those on EF. (PsycINFO Database Record

Chess databases as a research vehicle in psychology: Modeling large data

The game of chess has often been used for psychological investigations, particularly in cognitive science. The clear-cut rules and well-defined environment of chess provide a model for investigations of basic cognitive processes, such as perception, memory, and problem solving, while the precise rating system for the measurement of skill has enabled investigations of individual differences and expertise-related effects. In the present study, we focus on another appealing feature of chess—namely, the large archive databases associated with the game. The German national chess database presented in this study represents a fruitful ground for the investigation of multiple longitudinal research questions, since it collects the data of over 130,000 players and spans over 25 years. The German chess database collects the data of all players, including hobby players, and all tournaments played. This results in a rich and complete collection of the skill, age, and activity of the whole population of chess players in Germany. The database therefore complements the commonly used expertise approach in cognitive science by opening up new possibilities for the investigation of multiple factors that underlie expertise and skill acquisition. Since large datasets are not common in psychology, their introduction also raises the question of optimal and efficient statistical analysis. We offer the database for download and illustrate how it can be used by providing concrete examples and a step-by-step tutorial using different statistical analyses on a range of topics, including skill development over the lifetime, birth cohort effects, effects of activity and inactivity on skill, and gender differences.

Perceptions of Sexual Orientation From Minimal Cues.

People derive considerable amounts of information about each other from minimal nonverbal cues. Apart from characteristics typically regarded as obvious when encountering another person (e.g., age, race, and sex), perceivers can identify many other qualities about a person that are typically rather subtle. One such feature is sexual orientation. Here, I review the literature documenting the accurate perception of sexual orientation from nonverbal cues related to one's adornment, acoustics, actions, and appearance. In addition to chronicling studies that have demonstrated how people express and extract sexual orientation in each of these domains, I discuss some of the basic cognitive and perceptual processes that support these judgments, including how cues to sexual orientation manifest in behavioral (e.g., clothing choices) and structural (e.g., facial morphology) signals. Finally, I attend to boundary conditions in the accurate perception of sexual orientation, such as the states, traits, and group memberships that moderate individuals' ability to reliably decipher others' sexual orientation.

Being low prepares for being neglected: Verticality affects expectancy of social participation.

Previous research suggests that the established link of vertical position and self-assignment of social power affects the processing of social exclusion. We hypothesized that verticality-induced self-assignment of social power moderates the evaluation of exclusion via a change in subjective expectancy of social participation. Following this idea, a superior position-associated with higher power-was supposed to increase the sensitivity for a transition to social exclusion. The transition was simulated in a virtual ball tossing game (cyberball): an inclusionary block was followed by partial exclusion of the participant. The participants' vertical position relative to the co-players was varied in three experimental groups (superior vs. even vs. inferior). From inclusion to partial exclusion, we observed an increase of an event-related brain potential related to the violation of subjective expectancy (P3), and participants reported a corresponding increase in threat to social needs and negative mood. For participants at inferior position exclusionary effects on both, P3 and need threat, were less pronounced as compared to participants at even or superior position. These results indicate that verticality impacts basic cognitive processes of subjective expectancy formation. An inferior position already provides a bias for the loss of social power, and the transition to social exclusion is less unexpected.

The relation of the number of languages spoken to performance in different cognitive abilities in old age

ABSTRACTIntroduction: Findings on the association of speaking different languages with cognitive functioning in old age are inconsistent and inconclusive so far. Therefore, the present study set out to investigate the relation of the number of languages spoken to cognitive performance and its interplay with several other markers of cognitive reserve in a large sample of older adults. Method: Two thousand eight hundred and twelve older adults served as sample for the present study. Psychometric tests on verbal abilities, basic processing speed, and cognitive flexibility were administered. In addition, individuals were interviewed on their different languages spoken on a regular basis, educational attainment, occupation, and engaging in different activities throughout adulthood. Results: Higher number of languages regularly spoken was significantly associated with better performance in verbal abilities and processing speed, but unrelated to cognitive flexibility. Regression analyses showed that the number of languages spoken predicted cognitive performance over and above leisure activities/physical demand of job/gainful activity as respective additional predictor, but not over and above educational attainment/cognitive level of job as respective additional predictor. There was no significant moderation of the association of the number of languages spoken with cognitive performance in any model. Conclusions: Present data suggest that speaking different languages on a regular basis may additionally contribute to the build-up of cognitive reserve in old age. Yet, this may not be universal, but linked to verbal abilities and basic cognitive processing speed. Moreover, it may be dependent on other types of cognitive stimulation that individuals also engaged in during their life course.

Hierarchical dynamics of informational patterns and decision-making.

Traditional studies on the interaction of cognitive functions in healthy and disordered brains have used the analyses of the connectivity of several specialized brain networks-the functional connectome. However, emerging evidence suggests that both brain networks and functional spontaneous brain-wide network communication are intrinsically dynamic. In the light of studies investigating the cooperation between different cognitive functions, we consider here the dynamics of hierarchical networks in cognitive space. We show, using an example of behavioural decision-making based on sequential episodic memory, how the description of metastable pattern dynamics underlying basic cognitive processes helps to understand and predict complex processes like sequential episodic memory recall and competition among decision strategies. The mathematical images of the discussed phenomena in the phase space of the corresponding cognitive model are hierarchical heteroclinic networks. One of the most important features of such networks is the robustness of their dynamics. Different kinds of instabilities of these dynamics can be related to 'dynamical signatures' of creativity and different psychiatric disorders. The suggested approach can also be useful for the understanding of the dynamical processes that are the basis of consciousness.

The length of words reflects their conceptual complexity

Are the forms of words systematically related to their meaning? The arbitrariness of the sign has long been a foundational part of our understanding of human language. Theories of communication predict a relationship between length and meaning, however: Longer descriptions should be more conceptually complex. Here we show that both the lexicons of human languages and individual speakers encode the relationship between linguistic and conceptual complexity. Experimentally, participants mapped longer words to more complex objects in comprehension and production tasks and across a range of stimuli. Explicit judgments of conceptual complexity were also highly correlated with implicit measures of study time in a memory task, suggesting that complexity is directly related to basic cognitive processes. Observationally, judgments of conceptual complexity for a sample of real words correlate highly with their length across 80 languages, even controlling for frequency, familiarity, imageability, and concreteness. While word lengths are systematically related to usage—both frequency and contextual predictability—our results reveal a systematic relationship with meaning as well. They point to a general regularity in the design of lexicons and suggest that pragmatic pressures may influence the structure of the lexicon.

Fake feedback on pain tolerance impacts proactive versus reactive control strategies.

It is well-known that beliefs about one's own ability to execute a task influence task performance. Here, we tested the hypothesis that beliefs about a specific self-control capacity, namely pain tolerance, modulate basic cognitive control processes. Participants received fake comparative social feedback that their ability to tolerate painful stimulations was either very poor or outstanding after which they performed an unrelated go/no-go task. Participants receiving low-tolerance feedback, relative to high-tolerance feedback, were less successful at inhibiting their responses and more influenced by previous trial conditions, as indicated by an increased slowdown following errors and more failed inhibitions following go-trials. These observations demonstrate a shift from a more proactive to a more reactive control mode. This study shows that providing feedback about one's own capacity to control impulsive reactions to painful stimulations directly influences low-level cognitive control dynamics.

The Disconnected Brain and Executive Function Decline in Aging.

Higher order speeded cognitive abilities depend on efficient coordination of activity across the brain, rendering them vulnerable to age reductions in structural and functional brain connectivity. The concept of "disconnected aging" has been invoked, suggesting that degeneration of connections between distant brain regions cause cognitive reductions. However, it has not been shown that changes in cognitive functions over time can be explained by simultaneous changes in brain connectivity. We followed 119 young and middle-aged (23-52 years) and older (63-86 years) adults for 3.3 years with repeated assessments of structural and functional brain connectivity and executive functions. We found unique age-related longitudinal reductions in executive function over and above changes in more basic cognitive processes. Intriguingly, 82.5% of the age-related decline in executive function could be explained by changes in connectivity over time. While both structural and functional connectivity changes were related to longitudinal reductions in executive function, only structural connectivity change could explain the age-specific decline. This suggests that the major part of the age-related reductions in executive function can be attributed to micro- and macrostructural alterations in brain connectivity. Although correlational in nature, we believe the present results constitute evidence for a "disconnected brain" view on cognitive aging.

The effect of animacy on metamemory.

Previous research has shown that the animacy quality of materials affects basic cognitive processes such as memory (i.e., animate stimuli are remembered better than are inanimate stimuli). This is referred to as the animacy effect. Little research has examined, however, whether this effect can be extended to higher cognitive processes such as metamemory. In the present studies, we investigated the influence of animacy on judgments of learning (JOLs) and the underlying basis of the animacy effect, namely, processing fluency and beliefs about the animacy effect. In Experiment 1, participants studied animate and inanimate words and made immediate JOLs. Results revealed that participants gave higher estimates for animate than they did for inanimate words. In Experiments 2a and 2b, we evaluated the contribution of processing fluency to the animacy effect either by measuring self-paced study time or by disrupting fluency by presenting half of the words in an easy or difficult font style. Results from both experiments indicated that processing fluency contributes minimally to the animacy effect. In questionnaire-based Experiment 3, participants estimated hypothetical participants would better remember the animate words than the inanimate words, suggesting the potential role of beliefs on the animacy effect on JOLs. To conclude, these findings suggest that animacy is a reliable cue when people monitor their learning in higher cognitive processes. The beliefs, not processing fluency, contribute substantially to the animacy effect on JOLs.
