Disgust as embodied loss aversion

A quickly expanding literature has examined the link between physical disgust and morality. This article critically integrates the existing evidence and draws the following conclusions: First, there is considerable evidence that experimentally induced disgust and cleanliness influence moral judgment, but moderating variables and attributional processes need to be considered. Second, moral considerations have substantial effects on behavioural concomitants of disgust, such as facial expressions, economic games and food consumption. Third, while disgust involves a conservation concern, it can manifest itself in both liberal and conservative political attitudes. Overall, disgust can be considered to form part of a behavioural loss aversion system aimed at protecting valuable resources, including the integrity of one’s body. Recommendations are offered to investigate the role of disgust more rigorously in order to fully capture its role in moral life.     

The spacing effect in older and younger adults: does context matter?

Age-related memory change has been a topic of much investigation in recent years, including spacing benefits and reliance on contextual cues. We manipulated the spacing schedule and the context of learning and observed the effects on long-term recall ability in healthy older and younger adults. After learning Swahili–English word pairs, half practiced immediately (massed) and half practiced 24 h later (spaced) either in the same room or a different room (context) from the initial session. A final recall test 10 days after the practice session occurred in the same room as the first session. Participants in the spaced condition remembered more than those in the massed condition 10 days later. Younger adults remembered more word pairs than older adult participants. Context change eliminated the spacing benefit for both age groups.     

Global/local processing of hierarchical visual stimuli in a conflict–choice task by capuchin monkeys (<Emphasis Type="Italic">Sapajus</Emphasis> spp.)

In the last two decades, comparative research has addressed the issue of how the global and local levels of structure of visual stimuli are processed by different species, using Navon-type hierarchical figures, i.e. smaller local elements that form larger global configurations. Determining whether or not the variety of procedures adopted to test different species with hierarchical figures are equivalent is of crucial importance to ensure comparability of results. Among non-human species, global/local processing has been extensively studied in tufted capuchin monkeys using matching-to-sample tasks with hierarchical patterns. Local dominance has emerged consistently in these New World primates. In the present study, we assessed capuchins’ processing of hierarchical stimuli with a method frequently adopted in studies of global/local processing in non-primate species: the conflict–choice task. Different from the matching-to-sample procedure, this task involved processing local and global information retained in long-term memory. Capuchins were trained to discriminate between consistent hierarchical stimuli (similar global and local shape) and then tested with inconsistent hierarchical stimuli (different global and local shapes). We found that capuchins preferred the hierarchical stimuli featuring the correct local elements rather than those with the correct global configuration. This finding confirms that capuchins’ local dominance, typically observed using matching-to-sample procedures, is also expressed as a local preference in the conflict–choice task. Our study adds to the growing body of comparative studies on visual grouping functions by demonstrating that the methods most frequently used in the literature on global/local processing produce analogous results irrespective of extent of the involvement of memory processes.     

Early markers of lexical stress in visual word recognition

The goal of the present study was to investigate the time-course of suprasegmental information in visual word recognition. To this aim we measured event-related brain potentials (ERPs) during a simple lexical decision task in Italian. Two factors were manipulated: Stress dominance (the most frequent stress type) and stress neighborhood consistency (the proportion and number of existent words sharing orthographic ending and stress pattern). Participants were presented with target words either bearing dominant (on the penultimate syllable; 'graNIta,' 'seNIle,' slush, senile) or non-dominant stress (on the antepenultimate syllable; 'MISsile,' 'BIbita,' missile, drink), and either having a consistent (graNIta, MISsile) or an inconsistent stress neighborhood (seNIle, BIbita). Our results showed in the initial stages of processing an effect that we interpreted as an early orthographic marker of stress neighborhood in interaction with dominance. Later, from 250 ms after target onset, a marker of the lexical stress difference also emerged. The role of stress assignment in word recognition is discussed.     

Are Children Attracted to Play Elements with an Open Function?

Abstract

The present study aimed to determine the degree to which play elements have an “open function”, and whether children are attracted to them. The architect van Eyck hypothesized that play elements with an open function attract playing children because such elements do not suggest a certain type of behavior and are, thus, likely to stimulate the children’s creativity. Children of three different age groups (5-6, 7-8, and 11-12?years of age) played freely in a Parkour playground that consists of play elements that were supposed to vary in the degree of having an open function. Based on the judgments of parents on what action children will mainly perform on each of the elements, we concluded that the play elements indeed differed in the degree of having an open function. The play behavior, however, revealed that the children were less attracted to elements with an open function. The implications of these findings are discussed.     

The relationship between maladaptive personality functioning and problematic technology use in adolescence: A cluster analysis approach

In the last two decades, scientific research has explored the problematic use of internet, videogames and mobile phones. However, there is still little consistent knowledge regarding the co-occurrence of problematic technology use and the role of maladaptive personality characteristics in adolescence. The present study aimed to investigate adolescents' styles of technology use with a cluster analysis approach focusing on personality functioning. The sample comprised 408 Italian adolescents (46.3% males) aged 11 to 18 years (M _age = 13.80; SD = 2.08). Data were collected using the Internet Addiction Test, the Videogame Dependency Scale, the Test of Mobile-Phone Dependence Brief Form and the Personality Inventory for DSM5 Brief Form. Results provided a four-cluster solution based on the co-occurrence of problematic technology use. The four clusters were labeled as follows: cluster 1: “Above average internet and mobile-phone use”; cluster 2: “Below average technology use”; cluster 3: “Above average videogame use”; and cluster 4: “Problematic technology use.” Analyses on demographic variables (e.g., gender and age) demonstrated significant differences between the four groups. Adolescents with high levels of problematic technology use reported greater overall personality dysfunction than the other three groups. This finding supported our hypothesis on maladaptive personality functioning in adolescents at risk for addiction. Finally, the Antagonism domain played a specific role in differentiating the severity of adolescents' involvement in technology use. Further studies are needed to confirm our findings and to plan preventive interventions as well as therapeutic treatments.     

Evaluation of the psychometrics properties of the alarm distress baby scale among 122 Brazilian children

The Alarm Distress Baby Scale (ADBB) aims at assessing infant withdrawal behavior. A previous validation study revealed acceptable reliability and validity indices. The present study investigated the psychometric properties of the scale in a larger sample from a culturally different population. Pediatricians evaluated the behavior of 122 infants, 2 and 19 months old, using the ADBB during routine physical consultation. Four investigators (two pediatricians and two nurses not specialized in pediatric care) examined video recordings of the evaluations. Results showed good interrater reliability coefficients among pediatricians and poor correlation when all professionals were grouped together. Test–retest reliability revealed good intraexaminer agreement (r = 0.91). The pediatricians' evaluation using the ADBB was compared with a psychiatric examination to investigate the scale's criterion validity. The cutoff point of 5 provided the best clinical validity (sensitivity of 79%, specificity of 81%). Results from construct validity showed that the scale had three dimensions. Comparison of the factor solution with other construct validity studies of the same instrument revealed similarities and differences. Results suggest that the ADBB may be a useful screening instrument to detect signs of psychiatric alterations related to withdrawal behavior in primary care services, and it is likely to provide consistent information.
