Working memory updating and the development of rule-guided behavior

The transition from middle childhood into adolescence is marked by both increasing independence and also extensive change in the daily requirements of familial demands, social pressures, and academic achievement. To manage this increased complexity, children must develop the ability to use abstract rules that guide the choice of behavior across a range of circumstances. Here, we tested children through adults in a task that requires increasing levels of rule abstraction, while separately manipulating competition among alternatives in working memory. We found that age-related differences in rule-guided behavior can be explained in terms of improvement in rule abstraction, which we suggest involves a working memory updating mechanism. Furthermore, family socioeconomic status (SES) predicted change in rule-guided behavior, such that higher SES predicted better performance with development. We discuss these results within a working memory gating framework for abstract rule-guided behavior.     

Social cognition models and health behaviour: A structured review

Abstract

A number of social cognition models have been developed to account for socio-demographic variations in health behaviour. This paper distinguishes between: (a) motivational, (b) behavioural enaction, and (c) multi-stage models of health behaviour. The models are evaluated in terms of advancement of existing knowledge and - where appropriate - predictive utility. Common themes that appear within- and between- these categories are discussed, with consideration of ways in which theory may be advanced by future research. Each approach has associated strengths and weaknesses, suggesting that a “consensus” approach to the study of health behaviour may prove fruitful. Identification of the key constructs across different model types would allow coherent integration and promote further understanding of the psycho-social determinants of health behaviour.     

Social emotions and social cognition in the development of social anxiety disorder

ABSTRACT

Social anxiety disorder (SAD) is one of the most prevalent mental disorders with serious individual impairments and societal costs. Little is known about the mechanisms involved in SAD development. Here, I propose that dysregulated social emotions (social fear and shyness) are crucial for SAD development and that these dysregulated social emotions originate in the disturbances in socio-cognitive abilities. The research from our lab confirmed this. It showed that behavioural and physiological indices of social fear contribute to the development of SAD in toddlerhood and early childhood. Later in childhood, between ages 4.5 and 7.5, we found a new risk factor for SAD―dysregulated shyness. Specifically, we found that negative shy expressions and prolonged physiological blushing (temperature increase) contribute to SAD development. Whereas elevated fear may be rooted in deficits in socio-cognitive skills, dysregulated shyness may be rooted in advanced socio-cognitive abilities. These findings imply that dysregulated social emotions play an important role in SAD and should be explicitly targeted in clinical treatments of SAD.     

Social cognition and the human brain

Humans are exceedingly social animals, but the neural underpinnings of social cognition and behavior are not well understood. Studies in humans and other primates have pointed to several structures that play a key role in guiding social behaviors: the amygdala, ventromedial frontal cortices, and right somatosensory-related cortex, among others. These structures appear to mediate between perceptual representations of socially relevant stimuli, such as the sight of conspecifics, and retrieval of knowledge (or elicitation of behaviors) that such stimuli can trigger. Current debates concern the extent to which social cognition draws upon processing specialized for social information, and the relative contributions made to social cognition by innate and acquired knowledge.     

Embodied cognition and skilled health behaviour

The present research examines health persuasion from an embodied cognition perspective by proposing that engaging the motor system during presentation of a health message will lead individuals to become more skilled at performing the prescribed behaviour. Participants watched a video on the importance of flossing while either imaging themselves flossing or imaging themselves flossing while minimally engaging the motor system (i.e. touching a piece of floss). Females (but not males) who touched an individual floss while watching the video demonstrated better flossing skills 1 week later. Over time, participants (both males and females) who engaged the motor system also developed more accessible attitudes and had a stronger relationship between their perceived flossing efficacy and actual flossing skill. Implications for the theories of embodied cognition and health interventions are discussed.     

Imprinted genes, cognition and behaviour

The idea that genes can influence behavioural predispositions and their underlying psychological determinants is becoming increasingly tractable. In this article, recent findings are reviewed on a special type of inheritance, related to the transmission of traits via what have been termed 'imprinted' genes. In imprinted genes one allele is silenced according to its parental origin. This results in the inheritance of traits down the maternal or paternal line, in contrast to the more frequent mode of inheritance that is indifferent to the parental origin of the allele. Drawing on the advances made possible by combining the approaches of cognitive neuropsychology, behavioural neuroscience and contemporary molecular genetics, the detailed evidence for imprinted effects on behavioural and cognitive phenotypes is considered, focusing on findings from mental disorders, Turner's syndrome and experimental work in animal models. As prevailing evolutionary theories stress an essential antagonistic role of imprinted effects, these data might link such apparently diverse issues as neurodevelopment and the vulnerability to mental disease with the 'battle of the sexes', as joined at the level of cognitive and behavioural functioning.

Social cognition in the first year

Although the study of infancy has answered many important questions about the human capacity for social cognition, the relatively young field of developmental social cognition is far from reaching its adulthood. With the merging of developmental, behavioral and neurocognitive sciences, some growing pains are in store. New work demonstrates that research into early social cognitive development must integrate various research fields and methods in order to achieve a more robust understanding of the nature and parameters of human social cognition.     

表征与认知发展

One of the major divergences between dynamical systems theory and symbolism lies in their views on the role of representation in cognition. From the perspective of development, the cognitive development could be divided into three levels: sensorimotor, imagery representation and linguistic representation. It is claimed that representation is not a sufficient condition though it is necessary for cognition. However, it does not mean that the authors agree with the notion of strong coupling in dynamicism that completely rejects representation.

A longitudinal study of gender-related cognition and behaviour

Gender schema theory proposes that children's acquisition of gender labels and gender stereotypes informs gender-congruent behaviour. Most previous studies have been cross-sectional and do not address the temporal relationship between knowledge and behaviour. We report the results of a longitudinal study of gender knowledge and sex-typed behaviour across three domains in children tested at 24 and 36 months (N = 56). Although both knowledge and sex-typed behaviour increased significantly between 2 and 3 years, there was no systematic pattern of cross-lagged correlations between the two, although some concurrent relationships were present at 24 months. Future longitudinal work might profitably focus on younger children using reliable preverbal measures of gender knowledge and employing a shorter lag between measurement times.     

A model of the hierarchy of behaviour, cognition, and consciousness

Processes comparable in important respects to those underlying human conscious and non-conscious processing can be identified in a range of species and it is argued that these reflect evolutionary precursors of the human processes. A distinction is drawn between two types of processing: (1) stimulus-based and (2) higher-order. For 'higher-order,' in humans the operations of processing are themselves associated with conscious awareness. Conscious awareness sets the context for stimulus-based processing and its end-point is accessible to conscious awareness. However, the mechanics of the translation between stimulus and response proceeds without conscious control. The paper argues that higher-order processing is an evolutionary addition to stimulus-based processing. The model's value is shown for gaining insight into a range of phenomena and their link with consciousness. These include brain damage, learning, memory, development, vision, emotion, motor control, reasoning, the voluntary versus involuntary debate, and mental disorder.     

Social cognition is not reducible to theory of mind: When children use deontic rules to predict the behaviour of others

The objective of this paper is to discuss whether children have a capacity for deontic reasoning that is irreducible to mentalizing. The results of two experiments point to the existence of such non‐mentalistic understanding and prediction of the behaviour of others. In Study 1, young children (3‐ and 4‐year‐olds) were told different versions of classic false‐belief tasks, some of which were modified by the introduction of a rule or a regularity. When the task (a standard change of location task) included a rule, the performance of 3‐year‐olds, who fail traditional false‐belief tasks, significantly improved. In Study 2, 3‐year‐olds proved to be able to infer a rule from a social situation and to use it in order to predict the behaviour of a character involved in a modified version of the false‐belief task. These studies suggest that rules play a central role in the social cognition of young children and that deontic reasoning might not necessarily involve mind reading.     

Social cognition and aggression in delinquent adolescent males

The relationship of aggression to several social cognitive variables in delinquent adolescent males was investigated. Subjects were fifty-eight institutionalized males identified by peers as high-aggressive or low-aggressive. Participants were administered measures of perspective taking, moral judgment, and person perception. The findings indicated that only perspective-taking ability was significantly related to aggressive behavior in delinquents. High-aggressive delinquents were less able to perceive others' viewpoints than were low-aggressive delinquents. These findings are consistent with previous research concerning perspective taking and aggression, but disconfirm research involving other social cognitive variables and aggression. Results further indicate the importance of studying social cognitive variables as they relate to relevant clinical behaviors.
