Cultural evolutionary psychology is still evolutionary psychology.

The cognitive gadgets theory proposes to reform evolutionary psychology by replacing the standard nativist and internalist approach to modularity with a cultural constructivist one. However, the resulting "cultural evolutionary psychology" still maintains some controversial aspects of the original neo-Darwinian paradigm. These assumptions are unnecessary to the cognitive gadgets theory and can be eliminated without significant conceptual loss.

The Nature of Culture: an eight-grade model for the evolution and expansion of cultural capacities in hominins and other animals.

Tracing the evolution of human culture through time is arguably one of the most controversial and complex scholarly endeavors, and a broad evolutionary analysis of how symbolic, linguistic, and cultural capacities emerged and developed in our species is lacking. Here we present a model that, in broad terms, aims to explain the evolution and portray the expansion of human cultural capacities (the EECC model), that can be used as a point of departure for further multidisciplinary discussion and more detailed investigation. The EECC model is designed to be flexible, and can be refined to accommodate future archaeological, paleoanthropological, genetic or evolutionary psychology/behavioral analyses and discoveries.

Epistemological problems in Cognitive Archaeology: an anti-relativistic proposal towards methodological uniformity.

Cognitive archaeology (CA) has an inherent and major problem. The coupling between extinct minds, brains and behaviors cannot be investigated in a laboratory. Without direct testability, there is a risk that theories in CA will remain merely subjective opinions in which "anything goes".

Same/different concept learning by capuchin monkeys in matching-to-sample tasks.

The ability to understand similarities and analogies is a fundamental aspect of human advanced cognition. Although subject of considerable research in comparative cognition, the extent to which nonhuman species are capable of analogical reasoning is still debated. This study examined the conditions under which tufted capuchin monkeys (Cebus apella) acquire a same/different concept in a matching-to-sample task on the basis of relational similarity among multi-item stimuli.

Identity concept learning in matching-to-sample tasks by tufted capuchin monkeys (Cebus apella).

The abstract concept of equivalence is considered one of the bases of higher-order cognition, and it has been the subject of considerable research in comparative cognition. This study examined the conditions under which tufted capuchin monkeys (Cebus apella) are able to acquire an identity concept. Six capuchin monkeys were trained to solve a visual matching-to-sample (MTS) task on the basis of perceptual identity.
