The role of physical and relational aggression in adolescents' friendship selection was examined in a longitudinal sample of 274 Chilean students from 5th and 6th grade followed over 1 year. Longitudinal social network modeling (SIENA) was used to study selection processes for aggression while influence processes were controlled for. Furthermore, the effects of network characteristics (i.e., re...

One of the main objectives of cognitive science is to use abstraction to create models that represent accurately the cognitive processes that constitute learning, such as categorisation. Relational knowledge is important in this task, since through the reasoning processes of induction and analogy over relations that the mind ”creates” categories (it later estabilishes causal relations between t...

The purpose of this work is to analise the cognitive process of the domain theories as it described in the Measurement Theorry and to develop a computational Machine Learning approach, which realise it. As a result the Relational Data Mining approach, proposed by the authors in the preceding books, is developed. We present this approach, as implementation of the cognitive process as it perceive...

This paper studies the laws of communicating sequential processes (CSP) with Z-like initial and final states. Instead of defining a large semantics including all observable aspects, we incrementally develop the model in three stages: partially correct relational model, then totally correct sequential model and finally the reactive-process model with states. The properties of each model are capt...

We have introduced probability in the UTP framework by using functions from the state space to real numbers, which we term distributions, that are embedded in the predicates describing the different program constructs. This has allowed us to derive a probabilistic theory of designs starting from a probabilistic version of the relational theory, and continuing further down this road we can get t...

Process-Aware Information System (PAIS) are IT systems that manages, supports business processes and generate large event logs from execution of business processes. An event log is represented as a tuple of the form CaseID, TimeStamp, Activity and Actor. Process Mining is an emerging area of research that deals with the study and analysis of business processes based on event logs. Process Minin...

Temporal binding, the process that enables association between discontiguous stimuli in memory, and relational organization, a process that enables the flexibility of declarative memories, are both hippocampus-dependent and decline in aging. However, how these two processes are related in supporting declarative memory formation and how they are compromised in age-related memory loss remain hypo...

This study investigated, the effects of pretransposition verbalizations upon subsequent transposition behavior and. posttransposition verbalizations of first-grade chil­ dren. The investigator found, that children who correctly verbalized, relational aspects of the stimuli following a transposition task had more relational responses to the transposition task than children who did not correctly ...

INTRODUCTION Episodic memory processes are supported by different subregions of the medial temporal lobe (MTL). In contrast to a unitary model of memory recognition supported solely by the hippocampus, a current model suggests that item encoding engages perirhinal cortex, whereas relational encoding engages parahippocampal cortex and the hippocampus. However, this model has not been examined in...

OBJECTIVES The Relational and Item-Specific Encoding task (RISE) was designed to assess contributions of specific encoding and retrieval processes to episodic memory in schizophrenia. This manuscript describes how a cognitive neuroscience functional imaging paradigm was translated for clinical research. METHODS The RISE manipulates encoding by requiring participants to decide whether stimuli ...
