Rethinking the Relationship between Social Experience and False-Belief Understanding: A Mentalistic Account

It was long assumed that the capacity to represent false beliefs did not emerge until at least age four, as evidenced by children’s performance on elicited-response tasks. However, recent evidence that infants appear to demonstrate false-belief understanding when tested with alternative, non-elicited-response measures has led some researchers to conclude that the capacity to represent beliefs emerges in the first year of life. This mentalistic view has been criticized for failing to offer an explanation for the well-established positive associations between social factors and preschoolers’ performance on elicited-response false-belief tasks. In this paper, we address this criticism by offering an account that reconciles these associations with the mentalistic claim that false-belief understanding emerges in infancy. We propose that rather than facilitating the emergence of the capacity to represent beliefs, social factors facilitate the use of this ability via effects on attention, inference, retrieval, and response production. Our account predicts that the relationship between social factors and false-belief understanding should not be specific to preschoolers’ performance in elicited-response tasks: this relationship should be apparent across the lifespan in a variety of paradigms. We review an accumulating body of evidence that supports this prediction

Think Fast! Mental-state Language is Related to the Speed of False-belief Reasoning in Adulthood

When tested appropriately, infants appear to demonstrate false-belief understanding in the first year of life. Some have argued that this is inconsistent with the well-established relationship between social experience and preschoolers’ false-belief performance. We argue that these two sets of findings are not inconsistent because the ability to attribute false beliefs to others is necessary but not sufficient for false- belief performance, and we propose several ways that one social factor, hearing and using mental-state language, might relate to false-belief performance throughout the lifespan. We tested this account by examining the relationship between adults’ use of mental-state language and their false-belief understanding. Participants’ use of mental-state language was related to how quickly they could accurately predict the behavior of agents on the basis of desires and beliefs. These findings provide the first evidence that mental-state talk and false-belief performance are related into adulthood

The Relationship Between Mental-state Language and False-belief Understandingin Adulthood

Research has revealed a robust relationship between preschooler’s use of mental-state language (e.g. think, know)and performance on false-belief tasks (e.g. Ruffman, Slade & Crow, 2002). However, investigations of this relationship withschool-aged children have shown mixed results, making it unclear whether mental-state talk continues to play a role in false-belief understanding following the preschool years (e.g. Charman & Shmueli-Goetz, 1998; Grazzini & Ornaghi, 2012). Thisdiscrepancy may result from the fact that preschooler’s talk has consistently been assessed during interpersonal interactions withpeers, siblings, and parents, while school-aged children’s talk has been assessed via descriptions of wordless picture books orabsent friends. The present study bridges this gap by exploring whether adults’ use of mental-state language during interactioncorrelates with their false-belief performance. In doing so, we help to shed light on an important issue in theoretical accountsof the development of false-belief understanding

Scenarios for the Agricultural Sector in South and East Mediterranean Countries by 2030

The paper builds predictive scenarios for the agricultural sector of eleven Mediterranean countries (Med 11), namely Algeria, Egypt, Israel, Jordan, Lebanon, Libya, Morocco, Palestine, Syria, Tunisia and Turkey. First, it assesses the performance trends of the Med 11 agricultural sector with a focus on production, consumption and trade patterns, incentives, trade protection policies and trade relations with the EU and productivity dynamics and their determinants. Secondly, it presents four scenarios based on the main value chains of the agriculture sector of Med 11: animal products, fruits and vegetables, sugar and edible oil, cereals and fish and other sea products. The four scenarios are: business as usual, Mediterranean One global Player, the Euro Mediterranean Area under threat and the EU and Med 11 as Regional Player

Validation of the StimQ2: A parent-report measure of cognitive stimulation in the home.

Considerable evidence demonstrates the importance of the cognitive home environment in supporting children's language, cognition, and school readiness more broadly. This is particularly important for children from low-income backgrounds, as cognitive stimulation is a key area of resilience that mediates the impact of poverty on child development. Researchers and clinicians have therefore highlighted the need to quantify cognitive stimulation; however existing methodological approaches frequently utilize home visits and/or labor-intensive observations and coding. Here, we examined the reliability and validity of the StimQ2, a parent-report measure of the cognitive home environment that can be delivered efficiently and at low cost. StimQ2 improves upon earlier versions of the instrument by removing outdated items, assessing additional domains of cognitive stimulation and providing new scoring systems. Findings suggest that the StimQ2 is a reliable and valid measure of the cognitive home environment for children from infancy through the preschool period
