Trust as a Meta‐Emotion

The aim of this article is to present trust as a meta‐emotion, such that it is an emotion that precedes first‐order emotions. It examines how trust can be considered a meta‐emotion by establishing criteria for identifying trust as a meta‐emotion. How trust plays out differently in aesthetic and ordinary contexts can provide another mode for investigating meta‐emotions. The article illustrates how it is possible to recognize these meta‐emotions in narratives. Finally, it presents one of the aims of trust, sharing knowledge between agents, when someone who provides testimony shares knowledge in an epistemic trust process with others. It shows a relationship construction between subjects and objects thanks to the trust, a meta‐emotion that represents emotional ties between subjects to achieve another emotion.     

Increasing task difficulty enhances effects of intersensory redundancy: testing a new prediction of the Intersensory Redundancy Hypothesis

Prior research has demonstrated intersensory facilitation for perception of amodal properties of events such as tempo and rhythm in early development, supporting predictions of the Intersensory Redundancy Hypothesis (IRH). Specifically, infants discriminate amodal properties in bimodal, redundant stimulation but not in unimodal, nonredundant stimulation in early development, whereas later in development infants can detect amodal properties in both redundant and nonredundant stimulation. The present study tested a new prediction of the IRH: that effects of intersensory redundancy on attention and perceptual processing are most apparent in tasks of high difficulty relative to the skills of the perceiver. We assessed whether by increasing task difficulty, older infants would revert to patterns of intersensory facilitation shown by younger infants. Results confirmed our prediction and demonstrated that in difficult tempo discrimination tasks, 5‐month‐olds perform like 3‐month‐olds, showing intersensory facilitation for tempo discrimination. In contrast, in tasks of low and moderate difficulty, 5‐month‐olds discriminate tempo changes in both redundant audiovisual and nonredundant unimodal visual stimulation. These findings indicate that intersensory facilitation is most apparent for tasks of relatively high difficulty and may therefore persist across the lifespan.     

Keeping track of time: evidence for episodic-like memory in great apes

Episodic memory, as defined by Tulving, can be described in terms of behavioural elements (what, where and when information) but it is also accompained by an awareness of one’s past (chronesthesia) and a subjective conscious experience (autonoetic awareness). Recent experiments have shown that corvids and rodents recall the where, what and when of an event. This capability has been called episodic-like memory because it only fulfils the behavioural criteria for episodic memory. We tested seven chimpanzees, three orangutans and two bonobos of various ages by adapting two paradigms, originally developed by Clayton and colleagues to test scrub jays. In Experiment 1, subjects were fed preferred but perishable food (frozen juice) and less preferred but non-perishable food (grape). After the food items were hidden, subjects could choose one of them either after 5 min or 1 h. The frozen juice was still available after 5 min but melted after 1 h and became unobtainable. Apes chose the frozen juice significantly more after 5 min and the grape after 1 h. In Experiment 2, subjects faced two baiting events happening at different times, yet they formed an integrated memory for the location and time of the baiting event for particular food items. We also included a memory task that required no temporal encoding. Our results showed that apes remember in an integrated fashion what, where and when (i.e., how long ago) an event happened; that is, apes distinguished between different events in which the same food items were hidden in different places at different times. The temporal control of their choices was not dependent on the familiarity of the platforms where the food was hidden. Chimpanzees’ and bonobos’ performance in the temporal encoding task was age-dependent, following an inverted U-shaped distribution. The age had no effect on the performance of the subjects in the task that required no temporal encoding.     

Optimal behavior and concurrent variable ratio-variable interval schedules

Concurrent variable ratio-variable interval (CONC VRVI) schedules of reinforcement, and the time-based analog of the same schedule (CONC VT*VT), have been used to determine if the matching law accounts for the distribution of choices between the behavior alternatives more accurately than the assumption that subjects distribute time between the alternatives to maximize total reinforcement rate. The results of those experiments leave room for interpretation. One problem is the lack of understanding of the theoretical outcomes associated with maximization in these schedules. A precise understanding of the characteristics of optimal behavior (OB) could help identify experimental evidence of OB. Here we derive equations that describe the optimal times the subject should spend on each alternative of the schedule. We provide a table of the optimal times for a wide range of parameter values of the schedule that experimenters can use to compare easily experimental results to the results expected if subjects behave optimally. We also derive a function m that relates matching and optimal performance and we prove interesting characteristics of the function. Finally, we describe features of OB with CONC VT*VT and with concurrent variable time schedules that can be used to identify evidence of OB.     

A cross-cultural study of trait self-enhancement, explanatory variables, and adjustment

We investigated trait self-enhancement, explanatory variables, and adjustment in European American (n = 141), Asian American (n = 72), Mexican (n = 141), and Filipino (n = 174) college students. Consistent with trait perspectives, students in all cultural groups rated their traits with moderate to high accuracy, using peer ratings as a criterion. European Americans did not exhibit self-enhancement relative to peers, but both self and peer ratings were higher (i.e., more positive) for European Americans than for the other three groups. Support was found for some, but not all, cultural psychology explanations of self-enhancement. In all cultural groups, self-enhancement was more associated with personal (intrapsychic) adjustment than interpersonal adjustment, as judged by peers. The results provided support for an integration of trait and cultural psychology perspectives.     

A multiple‐method analysis of appraisal–emotion relationships: The case of the prosocial intergroup emotions

Despite its status as a prominent set of theories for explaining the elicitation and differentiation of emotions, much appraisal theory and research offer little indication of the nature of the relationship expected between appraisals and emotions. Here, we present a three‐study, multiple‐method analysis in which we examine numerous ways of testing appraisal–emotion relationships using the “prosocial” intergroup emotions—sympathy, anger, and guilt—as an example. Results show that the set of appraisal dimensions that appears strongly characteristic of an emotion varies depending on the kind of appraisal—emotion relationship hypothesised and the experimental methodology/statistical analysis used. These findings demonstrate the utility of explicit theorising about the nature of the relationship between emotions and appraisals, and show how the hypothesised appraisal–emotion relationship and choice of methodology can affect the structure of appraisal theories. We recommend an analysis across multiple methods to provide a more complete picture of a given set of appraisal–emotion relationships.     

Reevaluating the initial impact of John Broadus Watson on American psychology: The necessity of comparative parameters

In recent decades, various studies have challenged the traditional view that John Broadus Watson's Behaviorist Manifesto prompted a psychological revolution. However, methodological hindrances underlie all these attempts to evaluate the impact of Watson's study, such as the absence of comparative parameters. This article remedies this problem by conducting a comparative citation analysis involving Watson and eight other representative psychologists of the time: J. R. Angell, H. Carr, J. M. Cattell, J. Dewey, G. S. Hall, W. James, E. L. Thorndike, and E. B. Titchener. Eight important American journals were scrutinized for the period between 1903 and 1923, a decade before and a decade after the publication of Watson's Manifesto. The results suggest that even if Watson's study cannot be taken as revolutionary, it had an impact between 1914 and 1923 that was close to Dewey's, Titchener's, and Thorndike's and higher than Angell's, Carr's, Cattell's, and Hall's, although distant from James's. Finally, some methodological implications of this study are discussed.     

Mediterranean diet and wellbeing: evidence from a nationwide survey

Objective: Although there is some evidence of the association between specific food groups, such as plant foods, and subjective wellbeing, this is the first study to assess the relationship between adherence to the Mediterranean dietary pattern and subjective wellbeing. Design: Data were collected in 2014–2015, within the Edad con Salud project, a follow-up study of a multistage clustered survey on a representative sample of the population of Spain. The final sample comprised 2397 individuals with ages ranging from 21 to 101 years. Main outcome measures: Experienced wellbeing (positive and negative affect) was measured using the Day Reconstruction Method, and evaluative wellbeing was assessed with the Cantril Self-Anchoring Striving Scale. Results: A higher adherence to the Mediterranean diet showed a small but statistically significant inverse relationship with negative affect (β?=??0.076, p=.001), and direct with evaluative wellbeing (β?=?0.053, p=.015), whereas it was not related to positive affect. Several components of the Mediterranean diet were independently associated with wellbeing. Conclusion: The results suggest that adherence to a dietary pattern such as the Mediterranean diet, and not only the isolated consumption of its components, is associated with a better subjective wellbeing.     

Validation and adaptation of the PACES scale of enjoyment of the practice of physical activity for Spanish adolescent girls

The goal of this study is to validate a Spanish version of the Physical Activity Enjoyment Scale (PACES, Kendzierski & DeCarlo, 1991), in the population of Spanish adolescent girls, and also to obtain a reduced version of the scale. For this purpose, reliability analysis was conducted, and construct validity was assessed in two steps: exploratory factor analysis and structural equation model with confirmatory factor analysis. The scale was administered to a sample of 2777 adolescent girls of Secondary Education, ages between 12-18 years. The results show the reliability of the instrument and the construct validity with a good fit of the model. The adapted scale was reduced to six items, a shorter and efficient scale that allows us to measure the enjoyment of physical activity.
