The assessment of executive functions to test the integrity of the nigrostriatal network: A pilot study.

Background: Parkinson's disease (PD) is a chronic neurodegenerative disorder characterized by motor and non-motor symptoms. The latter mainly include affective, sleep, and cognitive deficits. Non-demented PD patients often demonstrate impairments in several executive domains following neuropsychological evaluation.

What makes us more susceptible to false memories in the era of COVID-19? A focus on vaccines and Green Pass.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic was accompanied by an overabundance of fake news increasing the risk of developing false memories (FMs). Previous studies have shown that the relationship between fake news and FMs could be mediated by some individual variables, including attitudinal biases. We explored the role of these variables in true memories (TMs) and FMs formation, with special emphasis on vaccine- and Green Pass (GP)-related topics.

Objective Knowledge Mediates the Relationship between the Use of Social Media and COVID-19-Related False Memories.

The exposure to relevant social and/or historical events can increase the generation of false memories (FMs). The Coronavirus Disease 2019 (COVID-19) pandemic is a calamity challenging health, political, and journalistic bodies, with media generating confusion that has facilitated the spread of fake news. In this respect, our study aims at investigating the relationships between memories (true memories, TMs vs.

Understanding of Numerical Information during the COVID-19 Pandemic.

Media news during the Coronavirus Disease 2019 (COVID-19) pandemic often entail complex numerical concepts such as exponential increase or reproduction number. This study investigated whether people have difficulties in understanding such information and whether these difficulties are related to numerical competence, reflective thinking, and risk proneness. One hundred sixty-three participants provided answers to a numeracy scale focusing on complex numerical concepts relevant to COVID-19 (COV Numeracy Scale).

The Frontal Assessment Battery 20 years later: normative data for a shortened version (FAB15).

Objective: The Frontal Assessment Battery (FAB) is a neuropsychological tool largely used to assess executive functions. Prior studies found a marked ceiling effect for the prehension behavior subtest (PBT) in healthy and clinical populations. Aims of the present study were (i) to examine the psychometric properties of the FAB without the contribution of PBT and (ii) to provide normative data for a revised version of the FAB after exclusion of PBT (FAB15).

Psychometric properties of the STAI-Y scales and normative data in an Italian elderly population.

Background: Early detection of anxiety symptoms in older people is capital as it may be linked to increased physical/functional disabilities, onset and progression of neurodegenerative disorders, and poor cognitive functioning. Nonetheless, there is a paucity of psychometrically validated anxiety measures in the elderly.

Aims: This study aimed at assessing the psychometric properties of the State-Trait Anxiety Inventory-Form Y (STAI-Y) and providing the first normative data for the Italian elderly population.

Italian version of the Starkstein Apathy Scale (SAS-I) and a shortened version (SAS-6) to assess "pure apathy" symptoms: normative study on 392 individuals.

Objectives: The present normative study aimed to (1) develop the Italian version of the Starkstein Apathy Scale (SAS-I) and (2) construct a shortened version including only the most sensitive items to "pure apathy" experiences.

Methods: The normative sample included 392 healthy subjects. A regression-based procedure was used to explore the effects of sex, age, and education on the raw SAS-I score.

Daily exposure to digital displays may affect the clock-drawing test: from psychometrics to serendipity.

Background: The clock-drawing test (CDT) is a neuropsychological screening tool largely used to explore cognitive functioning. It requires participants to draw an analog clock face. Many studies have reported a good correlation between the CDT and the Mini-Mental State Examination (MMSE).

The Impact of Failures and Successes on Affect and Self-Esteem in Young and Older Adults.

Older adults are assumed to change their affect states in reaction to positive and negative stimuli across the life span. However, little is known about the impact of success and failure events on age-related changes in affect states and, particularly, in self-esteem levels. To fill this gap in the literature, in the present study changes in affect and self-esteem in 100 young (19-30 years) and 102 older adults (65-81 years) were assessed after participants experienced success and failure in a demanding cognitive task.

Characterizing cognitive inhibitory deficits in mild cognitive impairment.

Individuals with mild cognitive impairment -MCI- show relative weaknesses in executive functioning (EF), as well as poor memory, but the inhibition-related mechanisms behind EF impairment in MCI have not been examined systematically. The aim of the present study was to systematically investigate inhibitory function in individuals with MCI to ascertain whether pathological aging is characterized by deficits in inhibitory processes and whether such impairment is confined to specific inhibition-related mechanisms. Tasks assessing inhibition-related functions - i.

Effects of self-generated versus experimenter-provided cues on the representation of future events.

Most experimental studies of prospection focused on episodic forms of future events prompted by means of verbal cues. However, there is evidence suggesting that future events differ considerably according to whether they are produced in response to external, experimenter-provided verbal cues or they are self-generated. In the present study, we compared the quality, the phenomenal characteristics, the temporal distribution, and the content of imagined events prompted by experimenter-provided cues (i.

Desirable and undesirable future thoughts call for different scene construction processes.

Despite the growing interest in the ability of foreseeing (episodic future thinking), it is still unclear how healthy people construct possible future scenarios. We suggest that different future thoughts require different processes of scene construction. Thirty-five participants were asked to imagine desirable and less desirable future events.

Does episodic future thinking improve prospective remembering?

Extant findings suggest interesting avenues for the investigation of the potential relationship between EFT and PM. However, as they stand, they are inconclusive as to the causal role that EFT may play in aiding prospective remembering. In one Experiment, we showed that accuracy in a prospective memory (PM) task performed on the second day was significantly higher when participants, on the first day, had mentally simulated the sequence of events expected to occur on the second day, including the PM task, than when they had performed control tasks.

Future thinking in Parkinson's disease: an executive function?

Contrary to what was originally thought (Hassabis, Kumaran, Vann, & Maguire, 2007) recent data have shown that imagining the future is not entirely dependent on the hippocampus (Squire et al., 2010) and neuroimaging studies have demonstrated a frontopolar activation during future thinking tasks (Okuda et al., 2003).

What differentiates episodic future thinking from complex scene imagery?

We investigated the contributions of familiarity of setting, self-relevance and self-projection in time to episodic future thinking. The role of familiarity of setting was assessed, in Experiment 1, by comparing episodic future thoughts to autobiographical future events supposed to occur in unfamiliar settings. The role of self-relevance was assessed, in Experiment 2, by comparing episodic future thoughts to future events involving familiar others.

Normative data for a battery of free recall, cued recall and recognition tests in the elderly Italian population.

The present study aimed to provide normative data on a large sample of the elderly Italian population (N = 464; range of age = 49-94; range of education = 3-25) on both the word and the picture versions of a battery of free recall, cued recall, and recognition tests of memory. Results from multiple regression analyses showed that both age and education were significant predictors of performance. Therefore, norms were calculated taking into account these demographic variables.

Age-related differences in the attention network test (ANT).

This study investigates the effect of aging on alerting, orienting, and conflict resolution by assessing younger (mean age = 25.8) and older (mean age = 67.9) adults' performance in the Attention Network Test that combines, in a single experimental paradigm, a flanker task with alerting and orienting cues.

Episodic future thinking in amnesic mild cognitive impairment.

Results from behavioral studies of amnesic patients and neuroimaging studies of individuals with intact memory suggest that a brain system involving direct contributions from the medial temporal lobes supports both remembering the past and imagining the future (Episodic Future Thinking). In the present study, we investigated whether amnesic Mild Cognitive Impairment (aMCI) affects EFT. Amnesic MCI is a high-risk factor for Alzheimer's disease and is characterized by a selective impairment of episodic memory, likely reflecting hippocampal malfunctioning.

The role of past in the simulation of autobiographical future episodes.

Human beings' ability to envisage the future has been recently assumed to rely on the reconstructive nature of episodic memory (Schacter & Addis, 2007). In the present research, young adults mentally reexperienced and preexperienced temporally close and distant autobiographical episodes, and rated their phenomenal characteristics as well as their novelty. Additionally, they performed a delayed recognition task including remember-know judgments on new, old-remember, and old-imagine words.

Normative data for the Pyramids and Palm Trees Test in the elderly Italian population.

The Pyramids and Palm Tree Test (PPT) is a semantic memory test that measures the capacity to access detailed semantic information about words and pictures, necessary for the identification of the analogies, which link conceptually two perceptually, and functionally distinct entities. The present study aimed to provide normative data on a large sample of the elderly Italian population (N = 464; range of age = 49-94; range of education = 3-25) on both the word and the picture versions of the PPT. Results from multiple regression analyses showed that both age and education were significant predictors of performance in both the word and the picture versions of the PPT.

The role of switching, inhibition and working memory in older adults' performance in the Wisconsin Card Sorting Test.

The Wisconsin Card Sorting Test (WCST) is considered a typical executive test. However, several interesting questions are still open as to the specific executive processes underlying this task. In the present study, we explored how local and global switching, inhibition and working memory, assessed through the Number-Letter, the Stop Signal and the Reading Span tasks, relate to older adults' performance in the WCST.

Normal aging affects decisions under ambiguity, but not decisions under risk.

Old adults have to face many situations that require important decisions. In the present investigation, the authors examined the effects of aging on both decisions under ambiguity and decisions under risk. To this purpose, healthy young and old adults completed the Iowa Gambling Task (IGT) and the Probability-Associated Gambling task (PAG task).

Effects of age and mild cognitive impairment on direct and indirect access to arithmetic knowledge.

The present study aimed at investigating age-related changes and mild cognitive impairment (MCI) related effects in simple arithmetic. To pursue this goal, MCI patients, healthy old adults and young adults performed three computerised tasks. The production (e.

Age differences and the identity negative priming effect: an updated meta-analysis.

A recent meta-analysis (P. Verhaeghen & L. De Meersman, 1998a) revealed that older adults show a reliable but significantly reduced negative priming effect compared with young adults.

Evidence for age-related equivalence in the directed forgetting paradigm.

The directed forgetting paradigm involves, under particular experimental circumstances, inhibitory mechanisms, which operate to the successful forgetting of irrelevant words. The item-by-item cueing method (e.g.
