What users think about the differences between caffeine and illicit/prescription stimulants for cognitive enhancement
2012
Pharmacological cognitive enhancement (CE) is a topic of increasing public awareness. In the scientific literature on student use of CE as a study aid for academic performance enhancement, there are high prevalence rates regarding the use of caffeinated substances (coffee, caffeinated drinks, caffeine tablets) but remarkably lower prevalence rates regarding the use of illicit/prescription stimulants such as amphetamines or methylphenidate. While the literature considers the reasons and mechanisms for these different prevalence rates from a theoretical standpoint, it lacks empirical data to account for healthy students who use both, caffeine and illicit/prescription stimulants, exclusively f…
Inferring functional patterns of tool use behavior from the temporal structure of object play sequences in a non-human primate species.
2019
Abstract Inferring functional components of behavioral sequences is a crucial but challenging task. A systematic comparison of their temporal structure is a good starting point, based on the postulate that more functional traits are less structurally variable. We studied stone handling behavior (SH) in Balinese long-tailed macaques, a versatile form of stone-directed play. We tested the hypothesis that stones are used by male monkeys to stimulate their genitals in a sexual context (i.e., “sex toy” hypothesis). Specifically, two SH actions (i.e., “tap-on-groin” (TOG) and “rub-on-groin” (ROG), respectively the repetitive tapping and rubbing of a stone onto the genital area) gained functional …
Decreasing prevalence of specific anosmia to non-steroid odorants from childhood to adolescence
2020
International audience; Specific anosmia is defined as the inability to detect a particular odorant, despite a normal olfactory function. Previous studies reported sex-related difference in detection threshold to steroid odorants, like androstenone or androstadienone during adolescence, and boys showed an increased detection threshold with age. However, such investigations have not been performed for non-steroid odorants. Hence, the current study investigated sex- and age-related effects on the prevalence of specific anosmia in children/adolescents aged 5-14 years (n = 800) to non-steroid odorants. The detection thresholds of three non-steroid odorants (bacdanol, methylsalicylate, and 3-hyd…
Differences in between-reinforcer value modulate the selective-value effect in great apes (Pan troglodytes, P. Paniscus, Gorilla gorilla, Pongo abeli…
2015
We investigated how apes allocated their choices between 2 food options that varied in terms of their quantity and quality. Experiment 1 tested whether subjects preferred an AB option over an A option, where the A item is preferred to the B item (e.g., apple + carrot vs. apple). Additionally, we tested whether the length of the intertrial interval (ITI) affected subjects' choices. Five orangutans, 4 gorillas, 7 bonobos, and 10 chimpanzees received 3 types of trials: preference (A vs. B), quantity (AA vs. A), and mixed (AB vs. A where A is the preferred food). We used 3 food items that substantially differed in terms of preference (carrots, apples, and pellets). Subjects showed no overall pr…
The WHAAM Application: a Tool to Support the Evidence-Based Practice in the Functional Behaviour Assessment
2018
BackgroundThe most recent computing technologies can promote the application of evidence-based practice (EBP) in the field of applied behaviour analysis (ABA).ObjectiveThe study describes how the use of technology can simplify the application of EBPs in ABA.MethodsThe Web Health Application for ADHD Monitoring (WHAAM) application demonstrates this in the following two case studies. We are monitoring dysfunctional behaviours, collecting behavioural data, performing systematic direct observations, creating both visual baseline and intervention charts and evaluating the planned interventions using the TAU-U statistical index.ResultsSignificant positive changes of children’s problem behaviours …
Effects of Substantia Nigra pars compacta lesion on the behavioral sequencing in the 6-OHDA model of Parkinson’s disease
2019
The basal ganglia circuitry plays a crucial role in the sequential organization of behavior. Here we studied the behavioral structure of the animals after 21 days of 6-OHDA-induced lesion of the dopaminergic nigrostriatal system. Frequencies and durations of individual components of the behavioral repertoire were calculated; moreover, whether a temporal organization of the activity was present, it was investigated by using T-pattern analysis, a multivariate approach able to detect the real-time sequential organization of behavior. Six sham-depleted and six rats with unilateral 6−OHDA-lesion of the Substantia Nigra pars compacta were used. As to quantitative evaluations, the comparison betwe…
Efficacy of a cognitive and behavioral treatment for childhood obesity supported by the ETIOBE web platform
2019
Recently, the prevalence of childhood obesity has increased alar- mingly. Interventions combining eating habits, physical activity (PA), behavioral components, and family support have been shown to be effective, although variables such as self-efficacy beliefs and motivation seem to be important in achieving stable changes. Information and communication technologies (ICTs) can provide additional resources to traditional treatments. The objective is to analyze the efficacy of two treatments: a cognitive and behavioral treatment (CBT) focused on the promotion of healthy eating and PA habits, and this CBT intervention supported by a web platform (ETIOBE). Forty-seven obese children were random…
Measurement Invariance of the Short Version of the Problematic Mobile Phone Use Questionnaire (PMPUQ-SV) across Eight Languages
2018
The prevalence of mobile phone use across the world has increased greatly over the past two decades. Problematic Mobile Phone Use (PMPU) has been studied in relation to public health and comprises various behaviours, including dangerous, prohibited, and dependent use. These types of problematic mobile phone behaviours are typically assessed with the short version of the Problematic Mobile Phone Use Questionnaire (PMPUQ–SV). However, to date, no study has ever examined the degree to which the PMPU scale assesses the same construct across different languages. The aims of the present study were to (i) determine an optimal factor structure for the PMPUQ–SV among university populations using eig…
Validating the German version of the Quality of Relationship Inventory: confirming the three-factor structure and report of psychometric properties.
2012
Research on psychosocial influences such as relationship characteristics has received increased attention in the clinical as well as social-psychological field. Several studies demonstrated that the quality of relationships, in particular with respect to the perceived support within intimate relationships, profoundly affects individuals' mental and physical health. There is, however, a limited choice of valid and internationally known assessments of relationship quality in Germany. We report the validation of the German version of the Quality of Relationships Inventory (QRI). First, we evaluated its factor structure in a representative German sample of 1.494 participants by means of confirm…
Changes of attachment characteristics during psychotherapy of patients with social anxiety disorder : results from the SOPHO-Net trial
2018
Objectives Within a randomized controlled trial contrasting the outcome of manualized cognitive-behavioral (CBT) and short term psychodynamic therapy (PDT) compared to a waiting list condition (the SOPHO-Net trial), we set out to test whether self-reported attachment characteristics change during the treatments and if these changes differ between treatments. Research design and methods 495 patients from the SOPHO-Net trial (54.5% female, mean age 35.2 years) who were randomized to either CBT, PDT or waiting list (WL) completed the partner-related revised Experiences in Close Relationships Questionnaire (ECR-R) before and after treatment and at 6 and 12 months follow-up. The Liebowitz Social…
