Concern-induced negative affect is associated with the occurrence and content of mind-wandering

Previous research has shown that the content and frequency of mind-wandering episodes—the occurrence of thoughts that are both stimulus-independent and task-unrelated—are closely related to an individual’s future-related concerns. Whether this relationship is shaped by the affective changes that are usually associated with future-related concerns still remains unclear, however. In this study, we induced the anticipation of a negatively valenced event and examined whether the ensuing affective changes were related to the occurrence and content of mind-wandering during an unrelated attentional task. We found that the increase in negative affect following concern induction predicted the general frequency of mind-wandering episodes. Furthermore, mind-wandering episodes specifically directed at the induced concern were related to a lower decrease in negative affect during the attentional task. These results suggest that the negative emotional impact of future-related concerns is an important factor to be taken into consideration for the subsequent occurrence of mind-wandering episodes, which might in turn be involved in the maintenance of negative affect over time.     

Does he sound cooperative? Acoustic correlates of cooperativeness

The sound of the voice has several acoustic features that influence the perception of how cooperative the speaker is. It remains unknown, however, whether these acoustic features are associated with actual cooperative behaviour. This issue is crucial to disentangle whether inferences of traits from voices are based on stereotypes, or facilitate the detection of cooperative partners. The latter is likely due to the pleiotropic effect that testosterone has on both cooperative behaviours and acoustic features. In the present study, we quantified the cooperativeness of native French-speaking men in a one-shot public good game. We also measured mean fundamental frequency, pitch variations, roughness, and breathiness from spontaneous speech recordings of the same men and collected saliva samples to measure their testosterone levels. Our results showed that men with lower-pitched voices and greater pitch variations were more cooperative. However, testosterone did not influence cooperative behaviours or acoustic features. Our finding provides the first evidence of the acoustic correlates of cooperative behaviour. When considered in combination with the literature on the detection of cooperativeness from faces, the results imply that assessment of cooperative behaviour would be improved by simultaneous consideration of visual and auditory cues.     

A longitudinal examination of early communicative development: Evidence from a parent‐report questionnaire

The present research employed a longitudinal design to assess the verbal and non‐verbal communicative abilities of a sample of 104 children, using two different parent‐report instruments: the Questionnaire for Communication and Early Language (QCEL) development at 12, 16, and 20 months, and the Italian adaptation of the MacArthur–Bates Communicative Development Inventories: Words and Gestures at 23 months. The results supported and extended previous data about the validity of the QCEL, by showing that: (1) both verbal and non‐verbal variables predicted the level of language development at 23 months; (2) children classified as at‐risk with the QCEL had reduced vocabulary size and a lower number of sentences at 23 months; (3) early individual differences in the use of words and gestures were associated with later differences in linguistic abilities. It is concluded that the longitudinal use of the QCEL questionnaire can provide useful information about language development.     

Metacognitive Therapy Focused on Psychosocial Function in Psychosis

Metacognitive Insight and Reflection Therapy is a manual-based individual psychotherapy aimed at enhancing four metacognitive processes through patient’s personal narratives which may promote recovery by helping individuals suffering from schizophrenia to develop a richer and more integrated sense of self. This study is a single case analysis of the effects of a meta-cognitively oriented CBT on residual psychotic symptoms and functional targets. Outcome measures (PANNS, PDI 21, BAVQ-R, PSP, MAS-A) were collected at two different times: pre-CBT and 1-year. Results showed reductions in the distress, preoccupation and conviction associated with delusions and improvements in metacognitive abilities, social functioning, hopefulness and of the sense of self-confidence to cope with the psychotic symptoms. Adopting a metacognitive perspective during psychotherapy had several benefits: to foster the development of therapeutic alliance, to allow the patient to assess the efficacy and acknowledge the consequences of the different strategies he could use to cope with his symptoms and to question the predominance of his delusions in his life. To conclude, Metacognitive Reflection and Insight Therapy seem particularly adapted to address psychosocial issues, such as social or work functioning.     

Role of action observation and action in sequence learning and coding

A complex sequence learning task was used to determine if the type of coding acquired through physical practice (PP), observation of the stimulus (Obs-S), or observation of stimulus and action (Obs-SA) differs between conditions and whether the type of observation influences subsequent learning of the task when physical practice was permitted. Participants in the Obs-S group were permitted to watch the sequentially illuminated stimuli on the screen. In the Obs-SA group participants could see both flexion-extension movements of the model's arm performing the sequence and the sequentially illuminated stimuli on the screen. Participants in the PP group actually performed the 16-element sequence with their dominant right arm. Delayed retention tests and two inter-manual transfer tests were completed following each of two acquisition sessions. First, the data indicated that learning the sequence structure, as revealed by response time per element, occurred similarly irrespective of the initial practice condition. Secondly, the movement sequence appeared to be coded in abstract visual-spatial coordinates resulting in effector-independent performance. Finally, observing the model's action and sequential stimuli allows participants to transfer the perceived aspects of the movement sequence into efficient coordination patterns when additional physical practice is permitted.     

Creating semantics in tool use

This article presents the first evidence for a functional link between tool use and the processing of abstract symbols like Arabic numbers. Participants were required to perform a tool-use task after the processing of an Arabic number. These numbers represented either a small (2 or 3) or a large magnitude (8 or 9). The tool-use task consisted in using inverse pliers for gripping either a small or a large object. The inverse pliers enable to dissociate the hand action from the tool action in relation to the object (i.e., closing the hand led to an opening of the tool and vice versa). The number/tool hypothesis predicts that the quantity representation associated with Arabic numbers will interact with the action of the tool toward the object. Conversely, the number/hand hypothesis predicts that the quantity associated with numbers will interact with the action of the hand toward the tool. Results confirmed the first hypothesis and rejected the second. Indeed, large numbers interacted with the action of the tool, such that participants were longer to perform an “opening-hand/closing-tool” action after the processing of large numbers. Moreover, no effect was detected for small numbers, confirming previous studies which used only finger movements. Altogether, our finding suggests that the well-known finger/number interaction can be reversed with tool use.
