Erotic subset for the Nencki Affective Picture System (NAPS ERO): cross-sexual comparison study

Abstract

Research on the processing of sexual stimuli has proved that such material has high priority in human cognition. Yet, although sex differences in response to sexual stimuli were extensively discussed in the literature, sexual orientation was given relatively little consideration, and material suitable for relevant research is difficult to come by. With this in mind, we present a collection of 200 erotic images, accompanied by their self-report ratings of emotional valence and arousal by homo- and heterosexual males and females (n = 80, divided into four equal-sized subsamples). The collection complements the Nencki Affective Picture System (NAPS) and is intended to be used as stimulus material in experimental research. The erotic images are divided into five categories, depending on their content: opposite-sex couple (50), male couple (50), female couple (50), male (25) and female (25). Additional 100 control images from the NAPS depicting people in a non-erotic context were also used in the study. We showed that recipient sex and sexual orientation strongly influenced the evaluation of erotic content. Thus, comparisons of valence and arousal ratings in different subject groups will help researchers select stimuli set for the purpose of various experimental designs. To facilitate the use of the dataset, we provide an on-line tool, which allows the user to browse the images interactively and select proper stimuli on the basis of several parameters. The NAPS ERO image collection together with the data are available to the scientific community for non-commercial use at http://naps.nencki.gov.pl.

Can pornography be addictive? An fMRI study of men seeking treatment for problematic pornography use

“…Subjects were recruited among men seeking treatment for PPU in two clinics in Warsaw. After the initial interview, patients were screened for sexual orientation (Inclusion criteria: exclusively or predominantly heterosexual on the Kinsey Scale (Kinsey et al, 1948;Wierzba et al, 2015) and no history of alcohol abuse (scores <7 on the Alcohol Use Disorder Identification Test (Saunders et al, 1993) or gambling problems (scores <3 on the South Oaks Gambling Screen (Lesieur and Blume, 1987). Patients meeting these criteria and having no contraindication for MRI were screened with the SCID-I (First and Gibbon, 2004) for OCD, ICDs, mood disorders, mania, anxiety disorders, psychotic disorders, history of substance abuse/dependence and hypersexual disorder according to criteria proposed by Kafka (Kafka, 2010).…”

The Complex Affective Scene Set (COMPASS): Solving the Social Content Problem in Affective Visual Stimulus Sets

“…For example, the Geneva Affective Picture Database (GAPED; Dan-Glauser & Scherer, 2011) predominantly includes unpleasant affective stimuli, such as images depicting violations of human and animal rights. The Nencki Affective Pictures System (NAPS;Marchewka, Żurawski, Jednoróg, & Grabowska, 2014) includes specific categories of affective images, as well as erotic (NAPS ERO; Wierzba et al, 2015) and fear-provoking (NAPS SFIP;Michałowski, Droździel, Matuszewski, Koziejowski, Jednoróg, & Marchewka, 2017) subsets. A number of welldeveloped sets include exclusively social stimuli, most of which are emotional faces (e.g., Karolinska Directed Emotional Face set; Lundqvist, Flykt., & Ohman, 1998;Montreal Set of Facial Displays of Emotion;Beaupre & Hess, 2005;NimStim;Tottenham et al, 2009; Pictures of Facial Affect; Ekman & Friesen, 1976; the Warsaw Set of Emotional Facial Expression Pictures; Olszanowski, Pochwatko, Kuklinski, Scibor-Rylski, Lewinski, & Ohme, 2015), and which offer the capacity to compare responses among human emotional facial expressions.…”

Gray matter volume differences in impulse control and addictive disorders

“…We collected structural brain images from all participants, with self-reported questionnaire data to investigate relationships between addiction symptoms and measures of GMV. All subjects provided written informed consent and were screened for sexual orientation (using the Polish version of Kinsey Scale; see [36]), alcohol abuse (using the Alcohol Use Disorders Identification Test (AUDIT); [37]), GD (using the South Oaks Gambling Screen (SOGS); [38], [39]) and CSBD (using the Sex Addiction Screening Test-Revised (SAST); [40], [41] and Brief Pornography Screening Test (BPS); [42]). Participants further completed the Obsessive Compulsive Inventory (OCI-R) [43], UPPS-P Impulsive Behavior Scale [44], [45] and according to Ashburner's [48] manual.…”
