The use of paralinguistic cues—including emoji—in computer-mediated communication has become prevalent in recent years. Brands and service providers have also been using these cues in their communication strategies. And yet, research examining how such emoji use influences customers’ perception and behavior is still scarce. In two experiments (comb...

Excessive sugar intake represents an increased risk of developing non-communicable diseases (e.g., obesity, cardiometabolic diseases, and dental diseases). Still, it is unclear whether people are aware of these adverse health outcomes. The current study systematically examined the extent to which people associate health conditions with excessive su...
Article
In Portugal, about one-fourth of the adult population exceeds the recommended daily amount of free sugars intake. This excessive consumption may be due to a lack of awareness of the sugar content of commonly available processed products. In two studies, we explored this assumption by asking participants (convenient samples) to evaluate the sugar co...
Article
The linguistic expectancy bias (LEB) reflects the tendency to describe expectancy-consistent behavior more abstractly than expectancy-inconsistent. The current studies replicate the LEB in Portuguese and examine it in a second language (English). Earlier studies found differences in processing a first language (L1) and a second language (L2) shapin...
Article
Food packaging usually includes multiple cues, including claims about nutrients that may modulate how the consumer perceives (and behaves towards) the product. In the current work, we systematically examined how different types of claims about sugar influenced the perception of food product categories (i.e., yogurts, ice creams, cookies, and breakf...
Article
Excessive sugar intake is one of the factors contributing to the alarming rates of childhood obesity and overweight in Portugal. Children's preferences and food consumption patterns are largely determined by the foods that are more familiar to them. Parents and caregivers are responsible for shaping children's eating habits since they are the ones...

Excessive free-sugar intake has become highly prevalent in numerous countries, and Portugal is not the exception. One product category that contributes to the daily intake of free sugars is breakfast cereals. In the current work, we identified 289 exemplars from two major retailers in Portugal and collected information on their nutritional profile...
Presentation
The emergence and transmission of false memories often occur in the course of social interaction. However, the cognitive mechanisms underlying the production of false memories in collaborative memory tasks remain rather unexplored. The present work used the misinformation paradigm to examine how misinformation is transmitted and incorporated in col...
Article
Pictures are often used as stimuli in several fields, such as psychology and neuroscience. However, co-occurring image-related properties might impact their processing, emphasizing the importance of validating such materials to guarantee the quality of research and professional practices. This is particularly relevant for pictures of common items b...

In this work, we examined knowledge about sugars and guidelines for its consumption and explored the relationship between knowledge and measures related to nutritional information processing as well as sugar consumption. Specifically, we asked participants (n = 1010 Portuguese) to categorize a set of ingredients (e.g., glucose, aspartame) regarding...
Article
Human memory likely evolved to serve adaptive functions, that is, to help maximise our chances of survival and reproduction. One demonstration of such adaptiveness is the increased retention of information processed in survival contexts, the so-called Survival Processing Effect (SPE). This study examined this effect in a native (L1) and in a second...
Article
The emergence and transmission of false memories is well documented in individual memory tasks. However, the examination of these processes in the context of social interaction still presents mixed findings. The present study further examines the potential of collaboration in minimizing the acceptance and retrieval of misinformation. In Experiment...
Chapter
One of the greatest challenges in the study of emotions and emotional states is their measurement. The techniques used to measure emotions depend essentially on the authors’ definition of the concept of emotion. Currently, two types of measures are used: subjective and objective. While subjective measures focus on assessing the conscious recognitio...
Chapter
This chapter discusses and clarifies the concepts and definitions of emotion, feeling, and mood. Although they refer to distinct phenomena, these concepts are normally used indiscriminately when someone refers to emotions. This is followed by a brief review of the literature on the main theories applied to the study of emotions. This reference to t...
Chapter
Robots should have characteristics that make the interaction effective and fluent for a successful Human-Robot Interaction (HRI). Since the emotions play a fundamental role in the human interaction process, many robots are introduced facial expressions, speech, body movements, among others to deepen the HRI. This chapter presents the exploration, d...
Chapter
Recent years have shown an increase in the importance of emotions applied to the Design field—Emotional Design. In this sense, the emotional design aims to elicit (e.g., pleasure) or prevent (e.g., displeasure) determined emotions, during human product interaction. That is, the emotional design regulates the emotional interaction between the indivi...

The Deese-Roediger-McDermott (DRM) paradigm is often used in the study of false memories. This paradigm typically uses lists of words associated with one critical lure. The primary objective of our study was to understand the production of false memories using the DRM paradigm when lists of words are associated with two critical lures. Three experi...

This work consists of a theoretical review with the aim of historically framing the way false memories have been studied. Although most of the studies on false memories have been developed since the last decade of the 20th century, the earliest dating from the late 19th century. With the aim of pointing out the great historical milestones in the r...

Do attitudes toward and perceptions of infidelity depend on perceived relationship quality? A prediction was made that there should be a positive correlation between perceived relationship quality and negative attitudes and perceptions of infidelity, and that these correlations should be stronger for males than for females. These predictions were c...

Studies on collaborative memory have revealed an interesting phenomenon called collaborative inhibition (CI) (i.e., nominal groups recall more information than collaborative groups). However, the results of studies on false memories in collaborative memory tasks are controversial. This study aimed to understand the production of false memories in c...

Background: The disruption of retrieval strategies hypothesis (Basden, Basden, Bryner, & Thomas, 1997) has been identified as the main reason for the occurrence of the collaborative inhibition effect. This study aims to test this hypothesis applying the same retrieval strategy to all participants. Method: To accomplish this, we compared nominal...
Thesis
We often are faced with the need to remember in group and it is in this sense that the studies in the area of human memory have been interested in the encoding and retrieval processes of information in group – collaborative memory. Thus, the main interest when studying collaborative memory is to understand if a group can retrieve more information t...
Conference Paper
A successful Human-Robot Interaction (HRI) depends on the empathy that the robot has the capability of instantiating on the user, namely through the expression of emotions. In this pilot study, we examined the recognition of emotions being expressed by a service robot in a virtual environment (VE), by university students. The VE was a corridor, neu...

Project
The project is funded FCT (LISBOA-01-0145-FEDER-028008) with ISCTE-IUL, CIS-IUL as the host institution. The research plan takes on a multi-method approach to examine the eating habits, the subjective and objective knowledge about the sugar content of processed foods, how such information is processed, and experimentally examines contextual (e.g., sugar-content labelling) and individual (e.g., attitudes, regulatory focus, motivations) factors underlying the perception and consumption of different types of high-sugar processed foods. Besides contributing to the literature, the findings are expected to inform evidence-based intervention strategies to address the current problem of high free sugars intake.
