Oceans of stimuli: an individual-based model to assess the role of olfactory cues and local enhancement in seabirds’ foraging behaviour

Animal Cognition - Oceans are extremely dynamic environments, which poses challenges for top-predators such as seabirds to find food resources. Yet, seabirds evolved sensorial abilities (olfactory...     

Validation of the University of California,Los Angeles Loneliness Scale (version 3) in Spanish older population: An application of exploratory structural equation modelling

Loneliness is a subjective and unpleasant experience associated to a variety of physical and mental health problems. Older people face an elevated risk of loneliness. It is measured through self-reported questionnaires, among which the most widely used one is the University of California, Los Angeles (UCLA) Loneliness Scale. The latest version of this scale is called UCLA-3, and it has not been validated in Spanish elderly population. This article aims to present a validation study of the Spanish version of the UCLA-3 for its use with older people, by establishing its reliability and validity. Data were obtained from the second wave of a longitudinal research conducted with older adults attending Lifelong Learning programs. The sample consisted of 335 people aged 55 years old or older. Sociodemographic data were collected, and loneliness was measured with the UCLA-3 and the de Jong Gierveld Loneliness Scale. Results have partially replicated a three factor structure already found in the literature in other populations. The present work provides relevant and innovative evidence, as this is the first time that the UCLA-3 was analysed using ESEM statistical approach in a Spanish elderly sample.

Who shows which kind of humor? Exploring sociodemographic differences in eight comic styles in a large Chilean sample

The present study investigates mean-level differences in eight comic styles (fun, benevolent humor, nonsense, wit, irony, satire, sarcasm, and cynicism) depending on the sociodemographic variables gender, age, education, political spectrum, and religious affiliation. A large and varied Chilean adult sample (N = 1,272, 60.1% women; age M = 39.94, SD = 17.33) was recruited in face-to-face interviews and online testing. They completed self-reports of the comic styles (the Comic Style Markers) and sociodemographic variables. Overall, small, but meaningful, differences in comic styles were found for the different sociodemographic groups. Men scored higher than women in all comic styles except for benevolent humor, and six styles decreased with age. Having lower education was associated with more cynicism, while the reverse pattern was found for satire and wit. Religious people showed lower scores in four styles than non-religious people, and cynicism was higher in those identifying with left wing rather than right-wing attitudes. The present study thus provides insights into who is more likely to engage in different kinds of humor in their everyday lives.     

Psychometric Properties of the Objectified Body Consciousness Scale (OBCS) in Spanish Preadolescents

Sex Roles - Objectification theory postulates that the body is constructed as a sexual object and is subject to observation and evaluation in such a way that a person may feel that their body is an...     

Effects of anisomycin on inhibitory avoidance in male and female CD1 mice

The antibiotic anisomycin inhibits protein synthesis, which much research has suggested is required for the formation of long-term memory. The present work studied the effects of acute subcutaneous administration of anisomycin on the consolidation of memory in an inhibitory avoidance task in CD1 mice of both sexes. The animals were separated by sex and randomly distributed into three groups: two groups were injected with 150 mg/kg anisomycin, one immediately after the training phase and the other 24 h later, while the control group received saline. The interval between training and test was four days. Anisomycin administrated immediately after training produced statistically significant impairment of memory, which was not observed when the drug was administered 24 h after training. No sex differences were observed in the effects of anisomycin. These results extend to female mice the memory impairing effects of anisomycin previously observed in males and endorse the hypothesis that the establishment of long-term memory depends on protein synthesis shortly after training.     

Differences in protective factors of substance use in early and middle adolescence

This study focuses on possible differences in protective factors of substance use in early and middle adolescence. These possible differences are analysed by means of the same structural equation model applied to two different samples of adolescents: the first sample is made up of 450 adolescents, ages 12 to 14 years, and second of 203 adolescents, ages 15 to 17 years. The results indicate that adequate family communication is a protective factor in both samples, whereas high social self-esteem is proposed as a risk factor in middle adolescence. The adolescent's family self-esteem and attitudes towards authority are also relevant factors in both samples. These results may have important implications in the development of future intervention programmes.
