The impact of physical activity and sex differences on intraindividual variability in inhibitory performance in older adults

It is well-known that processing speed and executive functions decline with advancing age. However, physical activity (PA) has a positive impact on cognitive performances in aging, specifically for inhibition. Less is known concerning intraindividual variability (iiV) in reaction times. This study aims to investigate the influence of PA and sex differences on iiV in inhibitory performance during aging. Healthy adults were divided into active and sedentary groups according to PA level. To analyse iiV in reaction times, individual mean, standard deviation and the ex-Gaussian parameters were considered. An interaction between activity level and sex was revealed, sedentary females being slower and more variable than sedentary men. No sex differences were found in the active groups. These results indicate that the negative impact of sedentariness on cognitive performance in older age is stronger for females. The present findings underline the need to consider sex differences in active aging approaches.     

Predictive factors of manual dexterity and cognitive performance at 17 years: a 10-year longitudinal study in a rural area of France

Studies of predictive factors of manual dexterity in adolescents and young adults are lacking. The present longitudinal study reports the relationship between cognitive and behavioural assessments at age 7 years and the schooling, cognitive performance, and manual dexterity at age 17 years. The participants were 65 schoolchildren, 30 boys and 35 girls, from a rural area in France. Assessment at age 7 years included the McCarthy scales and questionnaires measuring the behavior of the child, completed by the mother, the teacher, and the assessing psychologist. Assessment at age 17 years included schooling situation (whether they were in high school or not), cognitive testing (WAIS-R, Trail Making, Verbal Fluency, Cancel H, Stroop, Memory Assessment Scales), and manual dexterity testing (dynamometer, Finger Tapping, Santa Ana Test, Purdue Pegboard). After controlling for effects of parental education and IQ, a negative teachers' rating of children's behaviour and abilities in first-grade (7 years) was correlated with early cessation of schooling, but also, unexpectedly, with higher scores for manual dexterity at 17 years. Manual dexterity was not related to cognitive performance at 17 years. It is suggested that the relationship between manual and cognitive performance varies during development. Although manual exploratory behaviour is an important correlate of early cognitive development, manual dexterity is probably not related to later academic performance.     

A new set of 299 pictures for psycholinguistic studies: French norms for name agreement,image agreement,conceptual familiarity,visual complexity,image variability,age of acquisition,and naming latencies

Pictures are often used as stimuli in studies of perception, language, and memory. Since performances on different sets of pictures are generally contrasted, stimulus selection requires the use of standardized material to match pictures across different variables. Unfortunately, the number of standardized pictures available for empirical research is rather limited. The aim of the present study is to provide French normative data for a new set of 299 black-and-white drawings. Alario and Ferrand (1999) were closely followed in that the pictures were standardized on six variables: name agreement, image agreement, conceptual familiarity, visual complexity, image variability, and age of acquisition. Objective frequency measures are also provided for the most common names associated with the pictures. Comparative analyses between our results and the norms obtained in other, similar studies are reported. Finally, naming latencies corresponding to the set of pictures were also collected from French native speakers, and correlational/multiple-regression analyses were performed on naming latencies. This new set of standardized pictures is available on the Internet (http://leadserv.u-bourgogne.fr/bases/pictures/) and should be of great use to researchers when they select pictorial stimuli.     

Profiles of bystanders' motivation to defend school bully victims from a self‐determination perspective

This study was aimed at exploring which latent profiles emerge based on ratings of self‐determined motivation to defend victims of bullying, and to explore if they are related to bystander roles and victimization in bullying, as well as student–teacher relations. Data were collected from 1,800 Swedish and Italian students, with an age range between 10 and 18 years (M = 12.6, standard deviation = 1.74). The students completed a survey in their classrooms. Latent profile analysis was used to explore the possible clusters of individuals with similar ratings on the motivational variables. Multivariate analysis of variances were conducted to explore differences between the profiles in relation to their roles when witnessing bullying and to student–teacher relationships. Four latent profiles emerged. The profiles represented respondents (a) high in prosocial motivation, (b) high in externally extrinsic motivation, (c) intermediate in externally extrinsic motivation, and (d) with identified/introjected motivation. Multivariate analyses showed that reports of bystander roles when witnessing bullying, teacher–student relationships, and bullying victimization, significantly differed over the motivational profiles. The bystanders were unevenly distributed across the four groups and most individuals were categorized in the prosocial motivation group. Female and male bystanders were evenly distributed across clusters. The prosocial motivation group experienced victimization to a lesser extent than the other profile groups. Students in the intermediate externally extrinsic group were more likely to take the pro‐bully and outsider role during bullying. Concerning student–teacher relationships, the prosocial motivation group reported the closest relationships with their teachers, while the intermediate externally extrinsic group reported the most conflictual relationships.     

Assessing the effectiveness of drawing an autobiographical memory as a mood induction procedure in children

The objective of our study was to examine the effectiveness of a new version of the autobiographical recall procedure (i.e., drawing a happy personal event) in eliciting a positive mood in 6-, 8-, and 10-year-old children and to compare the drawing condition to the more classical telling condition. The mood of children was assessed before and after induction using the Self-Assessment Manikin (SAM) and across the two emotional dimensions of valence and arousal. The results showed that the drawing condition was as effective as the telling condition for inducing a positive mood. Furthermore, in the drawing condition, children reported feeling calmer than in the telling condition, suggesting that drawing was more likely to help children regulate their emotional state. The drawing procedure could be used in future research aiming to induce positive moods in school-aged children, to help further investigate the relationship between cognition and emotion.     

Behavioral evidence for a differential modulation of semantic processing and lexical production by aging: a full linear mixed-effects modeling approach

The effect of normal aging on lexical production and semantic processing was evaluated in 72 healthy participants. Four tasks were used, picture naming (PN), picture categorization (PC), numerical judgment (NJ), and color judgment (CJ). The dependence of reaction time (RT) and correct responses with age was accounted by mixed-effects models. Participants underwent neuropsychological testing for verbal, executive, and memory functions. The RTs increase significantly with age for all tasks. After parceling out the non-specific cognitive decline, as reflected by the NJ task, the RT for the PN task decreases with age. Behavioral data were interpreted in relation with neuropsychological scores. Our results suggest that (a) naming becomes more automatic and semantic processing slightly more difficult with age, and (b) a non-specific general slowdown of cognitive processing occurs with age. Lexical production remained unaltered, based on compensatory automatic processes. This study also suggests a possible slowdown of semantic processing, even in normal aging.     

We are our passions: The role of identity processes in harmonious and obsessive passion and links to optimal functioning in society

The Dualistic Model of Passion (DMP) proposes two types of passion, namely harmonious passion and obsessive passion. The DMP posits that the activity becomes part of one’s identity. However, little research assessed how the two types of passion relate to identity. Two important facets of identity hypothesized to be associated with passion are identity integration and identity styles. In two studies, we assessed these types of identity processes as determinants of passion. We expected the presence of positive associations between on the one hand informational identity style, identity integration, and their interaction term and HP on the other, and positive associations between normative identity style and OP. Participants in both studies (N1 = 107 and N2 = 135) completed the Identity Style Inventory-3, the Identity Integration subscale of the Multidimensional Self-Esteem Inventory, and the Passion Scale. In addition, in Study 2 we also looked at the relationships between passion and five indicators of the construct of Optimal Functioning in Society. Overall, results were consistent with our hypotheses.     

Differenzialdiagnose schizoaffektive Störung versus bipolare Störung

This case presentation describes a 22-year-old woman after an episode of psychotic mania. Manic-psychotic and depressive episodes, partially with psychotic symptoms, and different diagnoses have been documented for the past 5 years, raising the question of the differential diagnosis between bipolar disorder and schizoaffective disorder. Depending on the classification (ICD-10 versus DSM-5), schizoaffective disorder is defined differently. According to ICD-10, schizoaffective episodes can be diagnosed when affective and schizophrenic symptoms occur simultaneously. In a different approach, DSM-V requires psychotic symptoms in the absence of major mood episodes for at least 2 weeks in the course of the disorder.     

C. G. Jung and intuition: from the mindscape of the paranormal to the heart of psychology

Intuition is central in the work, practice, and philosophical legacy of C. G. Jung. In this paper, I will first discuss the importance of intuition for Jung in the paradigm usually designated the ‘paranormal’. Jung was attracted to intuition as an extra‐ordinary gift or function in the traditional sense, and this is considered here in relation to his 1896‐1899 Zofingia Lectures and 1902 On the Psychology and Pathology of So‐called Occult Phenomena: A Psychiatric Study. A significant development then occurred in 1913, when esotericist intuitions were turned toward psychological use with Jung's Red Book. There, his personal and private use of intuition – and we know how extraordinarily intuitive he was – led Jung to fully incorporate intuition at the core of his psychology. Not only in his practice, in the crucial intuitive form of empathy, but as we will see, also at the very heart of his theory. In 1921, Jung wrote Psychological Types, where intuition became one – the first – of the four fundamental functions and types of the psyche next to thinking, feeling, and sensation. In 1921, Jung proved to the world in rational argument that intuition was no longer a psychologist's hobby for table turning, but the most significant function of the psyche.     

On the Risks of Recycling Because of Guilt: An Examination of the Consequences of Introjection1

The present study sought to examine the influence of introjected beliefs on individuals’ vulnerability to counterattitudinal arguments. University students’ reasons for engaging in proenvironmental behaviors were assessed prior to their reading excerpts from a counterattitudinal article. The excerpts were written by a personally attractive or unattractive author and contained either weak or strong arguments against recycling. Our results show that individuals who were highly introjected about recycling (e.g., “I recycle because I would feel guilty if I didn't”) were influenced by the personal attractiveness of the source but not by the strength of the specific arguments. Specifically, a thought‐listing procedure revealed that introjection was associated with generating more favorable thoughts and fewer counterarguments about the anti‐recycling message when the author was personally attractive than when he was unattractive.
