Visual object imagery and autobiographical memory: Object Imagers are better at remembering their personal past

In the present study we examined whether higher levels of object imagery, a stable characteristic that reflects the ability and preference in generating pictorial mental images of objects, facilitate involuntary and voluntary retrieval of autobiographical memories (ABMs). Individuals with high (High-OI) and low (Low-OI) levels of object imagery were asked to perform an involuntary and a voluntary ABM task in the laboratory. Results showed that High-OI participants generated more involuntary and voluntary ABMs than Low-OI, with faster retrieval times. High-OI also reported more detailed memories compared to Low-OI and retrieved memories as visual images. Theoretical implications of these findings for research on voluntary and involuntary ABMs are discussed.     

Affect in Play Scale-Preschool Version: Validation on a Sample of School Age Italian Children

The Affect in Play Scale-Preschool version is a semi-structured measure of cognitive and affective pretend play processes using a 5?min standardized play task devised for preschool children. This study investigated an extension of the scale in a sample of 333 children, aged 6–10 years. Participants were assessed using another measure of play processes, the Affect in Play Scale, a divergent thinking task, the Alternate Uses Test, a measure of school coping, the School Coping measure, and a measure of empathy, the Index of Empathy for Children. External validity with these measures was investigated, using correlational analyses. Construct validity of the scale was assessed using a confirmatory factor analysis approach. A correlated two-factor structure with a cognitive and an affective factor demonstrated the best fit. Implications for the use of this extension to assess cognitive and affective processes in pretend play and developmental outcomes were discussed.     

Your Strengths are Calling: Preliminary Results of a Web-Based Strengths Intervention to Increase Calling

Cross-sectional research indicated that the application of signature strengths at work seemed to be crucial for perceiving a job as a calling. The present study aimed at testing this assumed causality in a random-assignment, placebo-controlled web-based intervention study. The intervention group (n = 83) was instructed to use their four highest character strengths more often at work for 4 weeks. Meanwhile the control group (n = 69) reflected about four situations (independent from the current workplace) where they excelled. For the evaluation of the effects of the two conditions, participants completed measures on calling and global life satisfaction before (Pretest), directly after the four-week training period (Posttest 1), and 3 (Posttest 2) and 6 months (Posttest 3) later. Calling significantly increased in the intervention group but not in the control group from Pretest to Posttest 1, and remained constant until Posttest 3. Global life satisfaction significantly increased in the intervention group but not in the control group from Pretest to Posttest 2 and from Posttest 1 to Posttest 3. That indicated that the changes on global life satisfaction were less steep than the changes in calling and lagged, but significant long lasting changes were observed likewise. Results supported the assumption that the application of strengths at work impacts calling and life satisfaction. Limitations as well as implications for research and practice are discussed.     

Do as I … Did! Long-term memory of imitative actions in dogs (<Emphasis Type="Italic">Canis familiaris</Emphasis>)

This study demonstrates long-term declarative memory of imitative actions in a non-human animal species. We tested 12 pet dogs for their ability to imitate human actions after retention intervals ranging from 1 to 24 h. For comparison, another 12 dogs were tested for the same actions without delay between demonstration and recall. Our test consisted of a modified version of the Do as I Do paradigm, combined with the two-action procedure to control for non-imitative processes. Imitative performance of dogs remained consistently high independent of increasing retention intervals, supporting the idea that dogs are able to retain mental representations of human actions for an extended period of time. The ability to imitate after such delays supports the use of long-term declarative memory.     

Deferred imitation and declarative memory in domestic dogs

This study demonstrates for the first time deferred imitation of novel actions in dogs (Canis familiaris) with retention intervals of 1.5 min and memory of familiar actions with intervals ranging from 0.40 to 10 min. Eight dogs were trained using the ‘Do as I do’ method to match their own behaviour to actions displayed by a human demonstrator. They were then trained to wait for a short interval to elapse before they were allowed to show the previously demonstrated action. The dogs were then tested for memory of the demonstrated behaviour in various conditions, also with the so-called two-action procedure and in a control condition without demonstration. Dogs were typically able to reproduce familiar actions after intervals as long as 10 min, even if distracted by different activities during the retention interval and were able to match their behaviour to the demonstration of a novel action after a delay of 1 min. In the two-action procedure, dogs were typically able to imitate the novel demonstrated behaviour after retention intervals of 1.5 min. The ability to encode and recall an action after a delay implies that facilitative processes cannot exhaustively explain the observed behavioural similarity and that dogs’ imitative abilities are rather based on an enduring mental representation of the demonstration. Furthermore, the ability to imitate a novel action after a delay without previous practice suggests presence of declarative memory in dogs.     

PhonItalia: a phonological lexicon for Italian

In this article, we present the first open-access lexical database that provides phonological representations for 120,000 Italian word forms. Each of these also includes syllable boundaries and stress markings and a comprehensive range of lexical statistics. Using data derived from this lexicon, we have also generated a set of derived databases and provided estimates of positional frequency use for Italian phonemes, syllables, syllable onsets and codas, and character and phoneme bigrams. These databases are freely available from phonitalia.org. This article describes the methods, content, and summarizing statistics for these databases. In a first application of this database, we also demonstrate how the distribution of phonological substitution errors made by Italian aphasic patients is related to phoneme frequency.     

Expressed Emotion,Parental Stress,and Family Dysfunction Among Parents of Nonclinical Italian Children

Expressed emotion (EE) is an index of the amount of emotion typically displayed by a family member or caretaker characterized by high emotional involvement, hostility or criticism. The aims of the current study were (a) to examine EE, stress and helplessness in childcare, and family functioning in mothers and fathers of elementary and junior high school children without clinical mental health problems living in a “nonclinical” family context; (b) to assess relationships between child age, gender, socio-economic status and EE; and (c) to investigate whether there are some factors—in a “normal family” context—that play a crucial role in the quality of EE. EE, assessed using the Five Minute Speech Sample (FMSS), and questionnaires assessing parenting alliance, family functioning, parenting stress index, and the parent’s state of helplessness in caring for the child were completed by a community-based Italian sample of mothers and fathers of children (N = 381) aged 6–14 years (M = 9.8, SD = 2.25). As expected, low rates in all FMSS variables were found for mothers and fathers, without significant differences between them. Mothers and fathers who showed high EE scores reported higher family non-adaptive functioning. Mothers also reported higher parental stress and higher Helplessness in caring for the child. Mothers’ stress and fathers’ reports of higher family non-adaptive functioning were the most consistent predictors of EE. Further research is needed to highlight associations between EE and family functioning.     

Attentional control in the attentional blink is modulated by odor

Increasing evidence suggests that `aromas have distinctive effects on the allocation of attention in space: Arousing olfactory fragrances (e.g., peppermint) are supposed to induce a more focused state, and calming olfactory fragrances (e.g., lavender) a broader attentional state. Here, we investigate whether odors have similar effects on the allocation of attention in time. Participants performed the attentional blink (AB) task, known to produce a deficit in reporting the second of two target stimuli presented in close succession in a rapid sequence of distractors, while being exposed to either a peppermint or a lavender aroma. In two experiments using a between-subjects and a within-subjects design, respectively, we show that the two odors have specific effects on attentional control: As compared with the calming lavender aroma, the arousing peppermint condition yielded a larger AB. Our results demonstrate that attentional control is systematically modulated by factors that induce a more or a less distributed state of mind.     

Sex differences in the attractiveness of hunter‐gatherer and modern risks

When compared with other demographics, young males are more likely to take a variety of risks (like skateboarding, using drugs) and use risky behaviors to attract romantic partners. This study extended research on risk by assessing the attractiveness of 101 different kinds of risks performed by males and females. As predicted, factor analysis revealed that the attractiveness of diverse risks clustered around two major dimensions: risks like those faced by hunter‐gatherer humans (e.g., handling fire and dangerous animals) and risks that are uniquely modern (e.g., driving without seat belts). Additionally, results confirmed that modern risks were rated as unattractive for both sexes, whereas hunter‐gatherer risks were rated as especially attractive when performed by males. Discussion focuses on cultural and evolutionary explanations for the link between risk and attractiveness.
