Nicholas Humphrey's social intelligence hypothesis proposed that the major engine of primate cognitive evolution was social competition. Lev Vygotsky also emphasized the social dimension of intelligence, but he focused on human primates and cultural things such as collaboration, communication and teaching. A reasonable proposal is that primate cognition in general was driven mainly by social co...

Dehydration is one of the ten most frequent diagnoses responsible for the hospital admission of elderly in the United States. It is associated with increased mortality, morbidity and an estimated cost of 1.14 billion per year (Xiao et al., 2004; Schlanger et al., 2010; Pretorius et al., 2013; Frangeskou et al., 2015). Older individuals are predisposed to dehydration encephalopathy as a result o...

What is the relation between spatial language and spatial cognition? Is the way we talk about space based on our non-linguistic spatial representations? Presently, there are at least two major hypotheses about the nature of this relation. On the one hand, there is a cognitive hypothesis. According to this hypothesis, spatial language is grounded on spatial cognition. Our non-linguistic spatial ...

BACKGROUND Social cognition has been implicated in the relationship between cognition and social functioning. AIMS To test the hypothesis that social cognition mediates the relationship between cognitive and social functioning. METHOD This was a 1-year longitudinal cohort study comparing three groups: 50 people with first-episode psychosis, 53 people with multi-episode schizophrenia and 55 ...

Please cite this article in press as: Seyfart j.anbehav.2015.01.030 The social intelligence hypothesis argues that competition and cooperation among individuals have shaped the evolution of cognition in animals. What do we mean by social cognition? Here we suggest that the building blocks of social cognition are a suite of skills, ordered roughly according to the cognitive demands they place up...

Visual cognition is of significant importance in certain imaging applications, such as security and surveillance. In these applications, an important issue is to determine the cognition threshold, which is the maximum distortion level that can be applied to the images while still ensuring that enough information is conveyed to recognize the scene. The cognition task is usually studied with imag...

In the present study, two different models of task complexity; namely, limited attentional capacity model and cognition hypothesis were examined. To this end, the manipulation of cognitive task complexity along +/- single task dimension on Iranian EFL learners’ production in terms of fluency was explored. Based on the results of the writing test of TOFEL (2004), 48 learners were selected as the...

Our hypothesis is that reflective cognition is necessary to achieve expert level performance in certain skills, and that reflective cognition can be seen as a secondary task in skill acquisition. To investigate to what extent people use and acquire complex skills and strategies in the domains of reasoning about others and natural language use, an experiment was conducted in which it was benefic...

The present study investigated the effects of cognitive complexity of pedagogical tasks on the learners’ uptake of salient features in the input. For the purpose of data collection, three versions of a decision-making task (simple, mid, and complex) were employed. Three intact classes (each 20 language learners) were randomly assigned to three groups.  Each group transacted a version of a decis...
