This article focuses on the validation of the French adaptation of the Basic Psychological Need Satisfaction and Frustration Scale (BPNSFS). According to the self-determination theory (SDT), this scale aims to assess satisfaction and frustration of the three basic psychological needs: competence, affiliation and autonomy. The objective of this research was to translate and validate the French version of the BPNSFS general context. The BPNSFS was completed by 1031 French students (M_age = 18.73; SD_age = 0.71; 66.89% of women). The psychometric properties were assessed through reliability, validity of construct based on internal structure, validity based on response processes and validity of prediction based on relations to other variables (i.e., self-worth and depression). The results confirmed the good reliability and validity of the scale. Therefore, the French version of the BPNSFS can be used to evaluate the satisfaction and frustration of basic psychological needs.

Approximately a third of depressive patients doesn’t respond to classical treatments and never experiences remission, justifying the need for novel therapeutic approaches. Research on the effect of psychedelics on consciousness and their therapeutic use is currently re-exploding. New data confirm that the psychedelic experience with psychological support is well-tolerated and diminishes immediately and durably the symptoms associated with anxiety and depression. This article gathers neurophysiological and psychological arguments which posit that psychedelics’ effect on depressive symptoms is due to their egolytic properties. Ego roles are adaptive by sustaining a sense of personal unity, continuity over time, and by guiding behavior in a coherent manner. However, ego dysfunctions can lead to cognitive biases and schemas involved in several psychopathological conditions, such as depression. Therefore, ego is a cornerstone of psychotherapy. It is proposed that default mode network functions and organization are somewhat consistent with the description of the ego. In major depression, hyperconnectivity of the default mode network's brain areas causes ego-focused and stereotyped symptoms such as ruminations and excessive tendency to self-judgment. On the contrary, psychedelics disrupt the functional connectivity of brain areas belonging to the default mode network, causing ego dissolution and releasing consciousness from its constrains. As a result, a flow of supplementary bottom-up limbic information can reach consciousness and the subject experiences a mystical sense of connectedness with what is usually seen as external. Even if the psychedelic state is transitory, its benefits on depressive symptoms persist over time. The reason is that the psychedelic experience leads to phenomena of insights and long-term perspective shifts. Thus, psychedelic-assisted psychotherapies appear as a promising option in the treatment of treatment-resistant depressions. Research on the effects of psychedelics in human is an exciting and promising field, which might continue to yield interesting results regarding their psychotherapeutic potentials and the link between brain and consciousness.

Studying for the first exam period is a big challenge for freshmen students, especially because they must be able to regulate emotions emerging from this new learning situation. Indeed, it is now recognized that cognitions and emotions interact in learning and that emotion can hinder or support it. However, we argue that it is not only emotions per se but rather how students manage them in the targeted situation (i.e. their emotional regulation skills) that impacts students’ adaptation to this academic context. Using an online survey, this study explored motives in emotion regulation, emotion goals and concrete emotion regulation strategies implemented by students during the preparation of a significant course evaluation. It focuses both on “why” students engage in emotion regulation in the target situation and on “how” this regulation is implemented. A thematic content analysis, processing the data of the 235 respondents, indicates that different motivations in emotion regulation are present among students (hedonic and instrumental motivations to regulate emotions) and that these motivations can be plural among the same students. When instrumental and hedonic motivations are both reported, although the students’ discourse argues that hedonic motivation (feeling good/better) is at the service of instrumental motivation (studying the course), concrete SRE prioritize well-being, through distraction from the course, more than the study of the course (the SRE rarely supports learning). In addition, the most reported emotion regulation strategy is distraction from the course (taking a break and doing something to distract yourself from the course), even in the absence of motivational conflicts. As a result, the theoretical model of motivated regulation (Tamir, 2009; Tamir, 2015) applied to this learning situation offers an innovative reading of why and how university students attempt to manage their emotions in order to learn successfully. Although the current study approaches only the conscious side of emotion regulation, it provides an original perspective on this complex phenomenon without ignoring the context in which it emerges. Finally, this insight should help students, teachers and educational coaches to see emotion regulation as necessary for learning and to set up pedagogical and coaching practices that support the development of SRE, adapted to the learning situation and linked to the emotional states that students wish to experiment in order to optimize learning.

Educational level is a factor of cognitive reserve and older adults with a higher level of formal education have a better memory performance than those having a lower educational level (Angel et al., 2010; Van Der Elst, Van Boxtel, Van Breukelen, & Jolles, 2005). Memory functioning can also be modulated by the beliefs and knowledge of a person about his/her own memory, that is, by his/her metamemory (Hultsch, Hertzog, & Dixon, 1987). The objective of this study was to examine the role of metamemory as a potential mediator of the effect of educational level on memory performance. Eighty-three older adults (60–80 years) participated in the experiment, they have been divided into two subgroups according to their educational level (high: 14.36 years and low level: 9.85 years). Episodic memory was evaluated with a cued recall task and metamemory by the Metamemory in Adulthood questionnaire (MIA). As shown by previous studies, results indicated that educational level had a significant effect on memory and metamemory, higher educational level was associated to better memory and metamemory capacities. At the MIA questionnaire, older adults with a high educational level affirmed using more internal and external strategies for learning, having higher motivation and perceiving less memory change with aging than older adults with a lower educational level. They also showed that the metamemory dimensions associated to the memory performance differed according to the educational level. For participants with a lower educational level, memory performance was correlated to the participants’ perception about their memory capacity and their knowledge about memory tasks, while for participants with a higher educational level, memory performance was correlated to the dimensions linked to memory control (strategies and motivation). Finally, the group effect was mediated by metamemory, specifically by the use of internal strategies. These results suggest that a prolonged educative experience would be associated to a better capacity to implement adapted strategies, which led individuals to maintain an optimal memory performance.

Introduction

Working memory (WM) training is known to produce benefits in older adults’ WM. Transfer effects to untrained abilities, however, remain controversial and several aspects are thought to influence the generalization of benefits, including the kind of stimuli used in the training tasks, an aspect rarely addressed in older adults.

Objective

The present study had two aims: (1) to test the efficacy of a visuospatial WM training procedure in older adults, in terms of specific and transfer effects; (2) to examine in two experiments whether the type of stimuli used in the training task influences the training's effectiveness. Experiment 1 adopted images with a neutral valence while experiment 2 used emotionally positive images based on evidence that older adults tend to remember positive stimuli better. In both experiments, specific training-related gains in a visuospatial WM task (the criterion task) and transfer effects on measures of verbal WM, visuospatial short-term memory, processing speed and reasoning were examined. Maintenance of training benefits was also assessed at an 8-month follow-up.

Method

Seventy older adult (63–75 years old) volunteers (35 for experiment 1, and 35 for experiment 2) were randomly assigned to a training or active control group. The same visuospatial WM training procedure was used in both experiments, manipulating only the type of stimuli used (neutral in experiment 1 and emotionally positive in experiment 2).

Results

In both experiments, only trained participants showed specific benefits in the WM criterion task. These gains were also maintained at the follow-up, but no transfer effects were identified.

Conclusion

Overall, our findings using the present visuospatial WM training paradigm suggest that it is less effective, in terms of transfer effects, than the same paradigm administered verbally in a previous study, regardless of the type of stimuli used in WM training tasks (neutral or emotionally positive stimuli).

The purpose of this study was to examine the effects of a cognitive stimulation program with games on scores to cognitive tests (processing speed, mental flexibility, working memory, inhibition) and how this program can benefit to a psycho-affective measure, self-esteem in older adults. Forty-eight participants over 60 years old took part in the experiment. They were divided into two groups: 1 group followed a program of cognitive stimulation using leisure activities with games and 1 control group in which people gathered every week. There were 8 sessions of cognitive stimulation using leisure activities like games, one-hour session a week. Measures have focused on speed of processing and executive functions (shifting, updating and inhibition). They have been evaluated before and after the training program. Results show that the cognitive stimulation program using leisure activities with games is effective on speed of processing, memory span, inhibition and self-esteem but shows no benefits on shifting and updating. These results indicate that it seems to be possible to enhance cognitive resources, inhibition and self-esteem using leisure activities with games as a tool for cognitive stimulation.

In this study we refer to Craik and Bialystok's model distinguishing the “knowledge” (cultural learning experience that forms the basis for knowledge of the world) and the “executive control” (set of operations that control and regulate cognitive performance) as two main factors susceptible accounting for the age-related negative effects on the cognitive functioning, and for a possible age-related protective effect. Thus, the aim of the present study was to examine the possible protective effect of these two factors on the age-related decline in a cued-recall task. Four age groups of participants (20–39 years, 40–59 years, 60–74 years and 75–90 years) were administered with a word-stem cued-recall test to assess episodic memory, a “vocabulary” sub-test of the WAIS-R to assess knowledge and a reading span test to assess control. Results showed an age-related effect on the episodic memory, the control performance and the knowledge measure, indicating that performance decreases with age. A GLM analysis revealed a positive effect of the knowledge and the control factors on the cued-recall performance, and interaction between age and the knowledge factor resulting from a positive effect of the knowledge level only for the youngest group of participants (20–39 years). Furthermore, results revealed an interaction between age and the control factor, indicating a positive effect of the control level for the two oldest groups of participants (60–74 years and 75–90 years). These results suggest that, contrary to the knowledge, the control factor could be an effective protection against the age-related negative effects on the episodic memory.

Age-related impairment in executive functioning has been found to explain partially the decrease of cognitive performance with aging. However, the practice of an executive test can improve performance to this test. In the present study, we investigated first how the practice of the Trail Making Test (TMT, flexibility test) may influence the age-related deficit to the performance in this test and then how the performance tended to improve, and at which pace, through the practice of this executive test. Two age groups of participants (young and older adults) practiced the TMT and were compared to two control groups (i.e., no practice between pre- and post-test). The practice groups’ scores were obtained at the end of each session. Globally, the results showed an improvement of performance (1) greater in the practice groups than in the control groups and (2) in practice groups, greater in older adults than in younger ones. Both younger and older adults progressed during the early practice sessions but the younger ones reached their optimal level earlier than the older adults who continued to improve over the sessions. These results could have a major impact on adapting cognitive stimulation programs to individual's characteristics such as age.
