Aversive learning overcomes appetitive innate responding in honeybees

Despite their miniature brain, honeybees have emerged as a powerful model for the study of learning and memory. Yet, they also exhibit innate responses to biologically relevant social signals such as pheromones. Here, we asked whether the bees’ developed learning capabilities allow them to overcome hardwired appetitive responses. Can they learn that attractant pheromones, that are not normally associated with a noxious stimulation in nature, predict the punishment of an electric shock? Immobilized honeybees were trained to discriminate two odorants, one that was paired with a shock and another that had no consequences. We measured whether they learned to produce aversive sting extension responses to the punished but not the non-punished odorant. One odorant was a neutral odor without innate value while the other was either an attractive pheromone (geraniol or citral) or an attractive floral odorant (phenylacetaldehyde). In all cases, bees developed a conditioned aversive response to the punished odorant, be it pheromone or not, and efficiently retrieved this information 1 h later. No learning asymmetries between odors were found. Thus, associative aversive learning in bees is strong enough to override preprogrammed responding, thus reflecting an impressive behavioral flexibility.     

Quand le genre s’en mêle : quelle conciliation entre vie professionnelle et vie privée ?

Declarations of conciliation between private life and professional life based on three factors (sex, gender and positions) are studied in this paper. Our goals were (i) to show that conciliation between the different life spheres need to be considered both in terms of conflict and of life enrichment; (ii) and to demonstrate that the gender variable has combined effects with sex variables, as well as with positions variables, over the perception of work in relation to family interferences in terms of nature (conflict/enrichment), intensity and direction (family over work versus work over family). The study, conducted with 240 employees of low or high professional positions, based on SWING and BSRI scales, shows the moderating effect of gender on the perceptions of conciliation, whether enriching or conflicting. Our results also allow us to conclude that congruent adjustment (masculine domination) of the levels of our three factors constitute a protecting factor for employees, while an incongruent adjustment can constitute a risk factor, this being especially verified for women.     

Artistic Representation and The Psychoanalytical Process

Instead of using a psychological grid when reading literature, Freud recommended that we let the actual writer instruct us. The same applies to artists. Here I will be asking two questions: can one make a formal comparison between the painter's visual approach, and the analyst's psychic approach which leads him to form a particular interpretation? Can one compare the spectator's feelings when a painting imposes itself on him, with the analyst's feelings when confronted with the silence of the analysand? Out of these two questions another, more general one arises: what can the psychoanalytical approach to artistic representation bring to the understanding of the analytical process?     

Development and validation of a measure of perceived relative deprivation in childhood

Childhood adversity is known to impact psychological functioning and physical health in later life, but research into the mechanisms responsible has been impeded by the absence of a suitable retrospective measure of perceived relative deprivation in childhood. We developed and validated scores of the Perceived Inequality in Childhood Scale (PICS). In total, 683 students from Liverpool University, Liverpool Hope University and the University of East London were sampled by means of online methods. The data were separated using odd–even methods and an exploratory factor analysis identified a 2 factor solution: perceived relative deprivation (12 items) and family social capital (4 items). The measure was then subjected to confirmatory factor analysis and a 3 factor structure was revealed. The scale was further validated against Index of Multiple Deprivation (IMD) scores of childhood addresses. The PICS is a brief, practical scale suitable for both small and large-scale research studies.     

Feeling low,thinking slow? Associations between situational cues,mood and cognitive function

ABSTRACT

Within-person changes in mood, which are triggered by situational cues, for example someone’s location or company, are thought to affect contemporaneous cognitive function. To test this hypothesis, data were collected over 6 months with the smartphone application (app) moo-Q that prompted users at random times to rate their mood and complete 3 short cognitive tests. Out of 24,313 people across 154 countries, who downloaded the app, 770 participants submitted 10 or more valid moo-Q responses (mean?=?23; SD?=?18; range 10–207). Confirming previous research, consistent patterns of association emerged for 6 different situation cues with mood and cognitive function: For example, being alone rather than with others when completing the app resulted in worse mood but better cognitive task performance. Notwithstanding, changes in mood and cognitive function were not coupled. The advantages and challenges of using smartphone technology for studying mood and cognitive function are discussed.     

Measuring the role of conditioning and stimulus generalisation in common fears and worries

Common and persistent fears may emerge through learning mechanisms such as fear conditioning and generalisation. Although there have been extensive studies of these learning processes in healthy but also psychiatric samples, many of the tasks used to produce conditioning and assess generalisation either use painful and aversive stimuli as the unconditioned stimuli (UCS), or suffer from poor belongingness between the conditioned stimuli and the UCS. Here, we present novel data from a paradigm designed to examine fear conditioning and generalisation in healthy individuals. Two female faces served as conditioned threat cue (CS+) and conditioned safety cue (CS?) respectively. The CS+ was paired repeatedly with a fearful, screaming face (unconditioned stimulus). Generalisation included intermediate faces which varied in their similarity to the CS+ and CS?. We measured eyeblink startle reflex and self-reported ratings. Acquired fear of the CS+ generalised to intermediate stimuli in proportion to their perceptual similarity to the CS+. Our findings demonstrate how fears of new individuals may develop based on resemblance to others with whom an individual has had negative experiences. The paradigm offers new opportunities for probing the role of generalisation in the emergence of common and persistent fears.     

Letter and Category Fluency in Normal Elderly Participants: a Population-Based Study

We studied variables influencing category and letter fluency in a large population-based sample of elderly participants. Letter and category fluency tasks were administered to 1133 unselected non-demented elderly participants in the Paquid cohort on normal and pathological aging. Age, education, principal lifetime occupation and depressive symptomatology independently influenced both category and letter fluency, while gender influenced only category fluency. A conceptualization measure (similarities) was found to influence fluency results mostly through education and prior occupation.     

Creative People Use Nonconscious Processes to Their Advantage

Although contentious, there is evidence to suggest that nonconscious processes contribute to creative output, particularly during refractory periods. However, no one has examined whether this break benefit differs as a function of creative ability. To address these issues, this investigation examined Wallas's (1926 Wallas , G. ( 1926 ). The art of thought . New York , NY : Harcourt Brace . [Google Scholar]) seminal theoretical framework of creativity. More specifically, the most controversial stage postulated by Wallas, the incubation phase, was empirically tested. A regression analysis demonstrated that productivity is significantly increased when creative people activate nonconscious processes in off-task or incubation periods. There is ongoing debate about the cause(s) of this incubation effect. This research provides evidence that the incubation effect results, at least partially, from nonconscious processing and that it provides greater benefit to more creative individuals. This suggests that highly creative people should be exposed to focus problems/challenges well in advance of objective deadlines, and have freedom to generate solutions outside of structured evaluation times.     

Students' Views on the Value of Psychological Research: A Contribution to Indigenising Psychology in Botswana

The goal of the study was to explore the value that psychology students accredit to psychological research in a country like Botswana where psychology is a relatively new discipline. Forty-five undergraduate students belonging to the first cohort of psychology students at the University of Botswana participated in the study (males = 7, females = 38, age range 18–23 years). Data were obtained from student essays and evaluated with Qualitative Content Analysis. Students were of the view that psychological research should (a) increase knowledge to better understand human beings and the world (epistemological value); (b) create awareness about psychology within society so as to to assist society in combating societal problems (societal value); (c) enhance individuals' understanding of psychology so as to to accept psychology (individual value); and (d) up-date psychological theories to ensure their applicability in present times (theoretical value). Considering students' views could play an important role in indigenising psychology in Botswana.
