Implicit ingroup metafavoritism: subtle preference for ingroup members displaying ingroup bias

The current article investigated how individuals evaluate ingroup members displaying either ingroup bias or egalitarian intergroup behaviors. The hypotheses predicted that on explicit responses a preference for the egalitarian ingroup member would emerge; in contrast, on more spontaneous and uncontrolled responses, a preference for the ingroup favoritist would result. Across four studies these hypotheses were confirmed for both minimal groups (Studies 1 and 2) and ethnic groups (Studies 3 and 4). Despite a verbal preference for those who behaved in an egalitarian way, an implicit ingroup metafavoritism was found. Overall, results indicated the presence of dual attitudes in the perception of ingroup members and the strict interconnection between intergroup behaviors and intragroup perception.     

Mood state indicators for adolescent athletes based on POMS multidimensional model

In this paper, we offer a short version of the POMS, with only 33 items, designed to apply to young Spanish athletes. One hundred and six male soccer players, aged 14 and 15 years, participated in the study. In order to select the proposed items, we tried to maximize three criteria: (1) items should be understood by subjects, (2) items should be perceived as conceptually similar as possible to the meaning of their respective factors, and (3) every factor should contain at least 4 items. To meet the second criterion, PROXSCAL scaling procedure was used, which allowed retaining the items closest to the meaning of each factor. All goodness-of-fit indexes were satisfactory in all the proximity analyses performed. In the proposed POMS version, the 33 items refer to seven mood factors, as follows: Tension (4 items), Depression (9 items), Anger (4 items), Vigour (4 items), Fatigue (4 items), Confusion (4 items), and Friendliness (4 items).     

Heterogeneous Fibring of Deductive Systems Via Abstract Proof Systems

Fibring is a meta-logical constructor that applied to two logicsproduces a new logic whose formulas allow the mixing of symbols.Homogeneous fibring assumes that the original logics are presentedin the same way (e.g via Hilbert calculi). Heterogeneous fibring,allowing the original logics to have different presentations(e.g. one presented by a Hilbert calculus and the other by asequent calculus), has been an open problem. Herein, consequencesystems are shown to be a good solution for heterogeneous fibringwhen one of the logics is presented in a semantic way and theother by a calculus and also a solution for the heterogeneousfibring of calculi. The new notion of abstract proof systemis shown to provide a better solution to heterogeneous fibringof calculi namely because derivations in the fibring keep theconstructive nature of derivations in the original logics. Preservationof compactness and semi-decidability is investigated.     

Concreteness effects in different tasks: implications for models of short-term memory

This study investigates concreteness effects in tasks requiring short-term retention. Concreteness effects were assessed in serial recall, matching span, order reconstruction, and free recall. Each task was carried out both in a control condition and under articulatory suppression. Our results show no dissociation between tasks that do and do not require spoken output. This argues against the redintegration hypothesis according to which lexical-semantic effects in short-term memory arise only at the point of production. In contrast, concreteness effects were modulated by task demands that stressed retention of item versus order information. Concreteness effects were stronger in free recall than in serial recall. Suppression, which weakens phonological representations, enhanced the concreteness effect with item scoring. In a matching task, positive effects of concreteness occurred with open sets but not with closed sets of words. Finally, concreteness effects reversed when the task asked only for recall of word positions (as in the matching task), when phonological representations were weak (because of suppression), and when lexical semantic representations overactivated (because of closed sets). We interpret these results as consistent with a model where phonological representations are crucial for the retention of order, while lexical-semantic representations support maintenance of item identity in both input and output buffers.     

The Efficacy Advantage: Factors Related to the Formation of Group Efficacy1

Extending previous research investigating factors related to the formation of group efficacy, this research examined predictors across cultures and groups of various types. Based on theories of collective cognition, hypothesized predictors included self‐efficacy, group affect, status differential, and collectivism. These were investigated using 2 methodologies (simulation and field study), each conducted in 2 cultural contexts. Self‐efficacy, group affect, and collectivism were significant predictors, explaining between 27% and 49% of the variance in group efficacy across the studies. Implications for theory and research are discussed.     

Does Time Fly 20 m above the Ground? Exploring the Role of Affective Response on Time Perception in a High‐risk Sport

A field study (n = 61) was performed in a Via Ferrata to explore how affective response influences time perception during an arousing activity in a real‐life setting (passing through a 69‐m‐long, 20‐m‐high, two‐rope bridge). Two questionnaires were administered (i) at the end point of the bridge (high‐arousing condition) and (ii) close to the end of the Via Ferrata (low‐arousing condition). Participants assessed their affect (arousal, valence, and dominance) and provided retrospective (duration estimation and passage of time judgments) and prospective (to produce a subjective minute using a stopwatch) temporal judgments. The results showed that the actual performance mediated the relationship between affect and retrospective time perception measures, with the exception of dominance, which directly predicted passage of time judgments. Regarding prospective measures, an increase in arousal was parallel to shorter temporal productions. The results are discussed in terms of the emotional factors underlying time perception in ecological contexts.Copyright © 2017 John Wiley & Sons, Ltd.     

Did the popsicle melt? Preschoolers’ performance in an episodic-like memory task

Episodic memory has been tested in non-human animals using depletion paradigms that assess recollection for the “what”, “where” and “when” (i.e., how long ago). This paradigm has not been used with human children, yet doing so would provide another means to explore their episodic memory development. Using a depletion paradigm, preschool-aged children were presented in two trials with a preferred food that was only edible after a short interval and a less-preferred food that was edible after the short and long intervals. Younger (mean?=?40 months) and older (mean?=?65 months) children tended to choose their preferred food after the short intervals, but did not switch to selecting their less-preferred food after the long intervals. Importantly, their choices did not differ with age. Although older children better remembered “what”, “where”, and “what is where” than did younger children, neither age group successfully estimated “how long ago” an event occurred. Finally, both age groups spontaneously recalled information about Trial 1. We also analysed the relation between the different measures used in the study but no clear patterns emerged. Results are discussed with respect to the cognitive mechanisms necessary to succeed in depletion paradigms and the measurement of episodic memory more broadly.     

Assessing Attachment to Parents and Peers in Middle Childhood: Psychometric Studies of the Portuguese Version of the People in My Life Questionnaire

The People in My Life questionnaire (PIML) is one of the few available self-report measures for assessing children’s representations of the relationship with attachment figures (parents and peers) in middle childhood. The current study presents validation studies of the PIML in a sample of Portuguese children aged between 8 and 12 years (N?=?314) and adolescents aged between 13 and 18 years (N?=?281). The original factor structure, composed of a second-order factor of attachment and three first-order factors (Trust, Communication, and Alienation), was confirmed for both scales (Parents Attachment and Peers Attachment) in the sample of children and replicated in the sample of adolescents using confirmatory factor analyses. The Portuguese version of the PIML showed adequate internal consistency and correlated as expected with measures of intrapersonal and interpersonal functioning (internalizing and externalizing problems, prosocial behavior, quality of life, self-compassion, and emotion regulation strategies). The PIML proved to be a psychometrically robust measure of children’s representations of their relationships with parents and peers, representing an important advance in the measurement of attachment in middle childhood.     

Letter names and phonological awareness help children to learn letter-sound relations

Two experimental training studies with Portuguese-speaking preschoolers in Brazil were conducted to investigate whether children benefit from letter name knowledge and phonological awareness in learning letter-sound relations. In Experiment 1, two groups of children were compared. The experimental group was taught the names of letters whose sounds occur either at the beginning (e.g., the letter /be/) or in the middle (e.g., the letter /‘eli/) of the letter name. The control group was taught the shapes of the letters but not their names. Then both groups were taught the sounds of the letters. Results showed an advantage for the experimental group, but only for beginning-sound letters. Experiment 2 investigated whether training in phonological awareness could boost the learning of letter sounds, particularly middle-sound letters. In addition to learning the names of beginning- and middle-sound letters, children in the experimental group were taught to categorize words according to rhyme and alliteration, whereas controls were taught to categorize the same words semantically. All children were then taught the sounds of the letters. Results showed that children who were given phonological awareness training found it easier to learn letter sounds than controls. This was true for both types of letters, but especially for middle-sound letters.     

Couple-Focused Interventions for HIV-Serodiscordant Couples During Transition to Motherhood

When HIV is transmitted between spouses or partners it is a major life trauma for both members of the couple. In Portugal, most women become aware of infection during routine prenatal examinations. A significant proportion of these women simultaneously face pregnancy, a deadly disease, and HIV-serodiscordance. In the context of maternity, there is a growing consensus that psychological intervention should address the couple as a unit. Couple-focused HIV interventions reinforce the importance of addressing relational dynamics within dyads, including communication, problem-solving skills, disclosure, and relationship quality issues. Immediate reproductive decisions, the possibility of mother-to-child transmission, and future perspectives impose additional challenges. Two case examples illustrate the application of couple-focused interventions. Also addressed are the specific problems and potentialities of this type of intervention.
