The still-face paradigm in Latin American mother-child dyads at 2 and 3 years: Effects of socioeconomic status and temperament.

The still-face paradigm (SFP) is a common method in infancy used to assess emotion regulation and interactions when an adult (typically the caregiver) abruptly stops a positive interaction with a child and switches to a more neutral affect. The effect of this paradigm has been studied in different countries and age ranges, but research in Latin America and with toddlers (e.g.

Emerging coherence and relations to communication among executive function tasks in toddlers: Evidence from a Latin American sample.

Recent work within early executive function (EF) seems to suggest that toddlers show distinct patterns of development, involving poorly correlated performance across EF tasks and significant improvements over relatively short periods of time. The present study sought to extend these findings by investigating evidence for these patterns in toddlers and the existence of more traditional patterns of EF (e.g.

[Development and Validation of a German-language Short Form of the Coping Strategies Inventory].

When an external and/or internal demand is found to be depleting one's resources, certain strategies are used to cope with the associated stress. Although a correlation between emotional suppression and a higher degree of pathological states has been demonstrated, there are no short instruments in German that include this stress coping strategy. Therefore, the aim of the present study was to translate the Coping Strategies Inventory and to develop a short version of the instrument.

Social and individual factors modulate parent-infant interactions: Lessons from free play sessions in an Argentine sample.

In this study, we aimed to explore the associations between socioeconomic status (SES) (i.e., parents' education and occupation, quality of the home and overcrowding), temperament styles (i.

Regulation During the Second Year: Executive Function and Emotion Regulation Links to Joint Attention, Temperament, and Social Vulnerability in a Latin American Sample.

Although a growing body of work has established developing regulatory abilities during the second year of life, more work is needed to better understand factors that influence this emerging control. The purpose of the present study was to examine regulation capacities in executive functions (i.e.

Frustration behaviors in domestic dogs.

During extinction a previously learned behavior stops being reinforced. In addition to the decrease in the rate of the instrumental response, it produces an aversive emotional state known as frustration. This state can be assimilated with the fear reactions that occur after aversive stimuli are introduced at both the physiological and behavioral levels.

Breed differences in dogs' (Canis familiaris) gaze to the human face.

Domestic dogs (Canis familiaris) have been submitted to a vast process of artificial selection and to date, there are hundreds of breeds that differ in their physical and behavioral features. In addition, dogs possess important skills to communicate with humans. Previous evidence indicates that those abilities are related to the domestication process and are modulated by instrumental learning processes.

Communication between domestic dogs (Canis familiaris) and humans: dogs are good learners.

Communication involves a wide range of behaviours that animals emit in their daily lives and can take place between different species, as is the case of domestic dogs (Canis familiaris) and humans. Dogs have shown to be successful at following human cues to solve the object choice task. The question is what are the mechanisms involved in these communicative abilities.

Incentive contrast in domestic dogs (Canis familiaris).

Dogs (Canis familiaris) trained to receive a preferred food (dry beef liver) from an experimenter learned to maintain a longer gaze on the experimenter than dogs receiving a less preferred food (dog pellets). Dogs downshifted from dry liver to pellets rejected food more frequently than nonshifted controls. Gaze duration also decreased in downshifted dogs below the level of a group always reinforced with pellets.

Learning and owner-stranger effects on interspecific communication in domestic dogs (Canis familiaris).

Domestic dogs are very successful at following human cues like gazing or pointing to find hidden food in an object choice task. They solve this kind of situation at their first attempts and from early stages of their development and perform better than wolves. Most of the authors proposed that these abilities are a domestication product, and independent from learning processes.

Effect of reinforcement, reinforcer omission and extinction on a communicative response in domestic dogs (Canis familiaris).

There is a controversy about the mechanisms involved in the interspecific communicative behaviour in domestic dogs. The main question is whether this behaviour is a result of instrumental learning or higher cognitive skills are required. The present investigations were undertaken to study the effect of learning processes upon the gaze towards the human's face as a communicative response.
