The impact of emotion on executive functioning is gaining interest. It has led to the differentiation of “cool” Executive Functioning (EF) processes, such as cognitive flexibility, and “hot” EF processes, such as affective flexibility. But how does affective flexibility, the ability to switch between cognitive and affective information, vary as a f...

Aims Negative and Positive urgency are emotion-related impulsivity traits that are thought to be transdiagnostic factors in psychopathology. However, it has recently been claimed that these two traits are closely related to each other and that considering them separately might have limited conceptual and methodological value. The present study aime...

Autobiographical memory plays a major role in the (re)construction of sense of identity, a recurrent issue after a traumatic brain injury (TBI). Although the recall of specific autobiographical events is frequently impaired in patients with TBI, little is known about how these changes affect their sense of self and identity. Thus, we examined self‐...

The 14-item Compulsive Internet Use Scale (CIUS) is one of the most frequently internationally adapted psychometric instruments developed to assess generalized problematic Internet use. Multiple adaptations of this instrument have led to versions in different languages (e.g., Arabic and French), and different numbers of items (e.g., from 5 to 16 it...

Decision-making impairments play a pivotal role in the emergence and maintenance of addictive disorders. However, a sound conceptualization of decision making as an umbrella construct, encompassing its cognitive, affective, motivational, and physiological subcomponents, is still lacking, preventing an efficient evaluation of the heterogeneity of de...
Article
Response inhibition is defined as one’s ability to voluntarily override an automatic or already initiated action when that action is inappropriate. Although a core mechanism of self-control, its association with sexual coercion perpetration and the impact of erotic cues on its exertion remain unknown.

Article
Anger outbursts constitute a frequent behavioural issue after a traumatic brain injury (TBI) and have a strong negative impact on the social outcomes resulting from the TBI. However, few studies have examined the efficacy of specific intervention strategies to reduce the frequency and intensity of anger outbursts. We therefore performed a single-ca...

Inappropriate social behaviours are among the most frequent behavioural sequelae after a traumatic brain injury (TBI) and may have a deleterious effect on the person’s social reintegration. The goal of the present study was to develop and validate an instrument to predict inappropriate social behaviour after a TBI, the Social Responding Task (SRT)....
Article
Full-text available
The body-shape-related stimuli used in most body-image studies have several limitations (e.g., a lack of pilot validation procedures and the use of non-body-shape-related control/neutral stimuli). We therefore developed a database of 61 computer-generated body-only pictures of women, wherein bodies were methodically manipulated in terms of fatness...

Full-text available
Background: Poor impulse control is a common feature in patients with Parkinson's disease (PD). However, before testing whether patients with PD and controls differ in impulsivity, one must assess whether impulsivity measures are invariant across groups. Consequently, we examined (a) the measurement and structural invariance of a scale assessing c...
Article
Procrastination is a widespread phenomenon described as the quintessence of self-regulatory failure. The aim of the present study was to explore the role of inhibition capacities (prepotent response inhibition and resistance to proactive interference), negative affect, and gender in this self-regulatory failure. One hundred thirteen participants co...
Article
Despite the intrinsic temporal nature of procrastination, little research has examined the link between this form of self-regulatory failure and the consideration of future consequences, and no study has addressed the link between procrastination and episodic future thinking. The aim of the present study was to explore these relationships. Particip...
Article
Full-text available
Neurobehavioral and self-awareness changes are frequently observed following traumatic brain injury (TBI). These disturbances have been related to negative consequences on functional outcomes, caregiver distress and social reintegration, representing therefore a challenge for clinical research. Some studies have recently been conducted to specifica...

Objectives: Apathy is frequently described following traumatic brain injury (TBI) and defined on the basis of three dimensions (emotional blunting, lack of initiative, lack of interest), which are commonly assessed by the Apathy Inventory (AI). The aims were (1) to explore the psychometric properties of this scale in the TBI population and the rela...
Article
Full-text available
Data analysis for single-case designs is an issue that has prompted many researchers to propose a variety of alternatives, including use of randomisation tests, regression-based procedures, and standardised mean difference. Another option consists in computing unstandardised or raw differences between conditions: the changes in slope and in level,...

Full-text available
To examine impulsivity changes after a severe traumatic brain injury (TBI) and to explore the relationships between impulsivity dimensions (urgency, lack of premeditation, lack of perseverance, sensation seeking), emotional/behavioural hyperactivation and 12-month outcome. Measures of emotional/behavioural hyperactivation and functional outcome wer...
Article
Full-text available
Emotions have recently been shown to interfere with the efficacy of inhibitory control. However, understanding their impact requires taking into account that inhibition is not a unitary construct, but consists of distinct functions underlain by specific mechanisms. In this study, 88 participants performed two emotional versions of classic laborator...

Implementation intentions have been shown to be a very effective strategy in improving prospective memory in older adults. However, their efficacy in improving inhibition has never been assessed in aging. We thus examined the efficacy of implementation intentions in a prospective memory task and an inhibition task in 87 older participants. Followin...
