{"title":"Learning in intimate connections: Conditioned fertility and its role in sexual competition.","authors":"Michael Domjan, Michael J Mahometa, R Nicolle Matthews","doi":"10.3402/snp.v2i0.17333","DOIUrl":"10.3402/snp.v2i0.17333","url":null,"abstract":"<p><strong>Background: </strong>Studies of sexual conditioning typically focus on the development of conditioned responses to a stimulus that precedes and has become associated with a sexual unconditioned stimulus (US). Such a sexually conditioned stimulus (CS) provides the opportunity for feed-forward regulation of sexual behavior, which improves the efficiency and effectiveness of the sexual activity.</p><p><strong>Objective and design: </strong>The present experiments were conducted to provide evidence of such feed-forward regulation of sexual behavior in laboratory studies with domesticated quail by measuring how many fertilized eggs were produced by the female after the sexual encounter. During the conditioning phase, male and female quail received a conditioned stimulus paired with the opportunity to copulate with each other.</p><p><strong>Results: </strong>Sexual conditioning increased the number of eggs that were fertilized as a consequence of copulation, especially if both the male and the female were exposed to the sexual CS. This conditioned fertility effect occurred with a range of CS durations and CS types. The conditioned fertility effect also occurred in situations involving sexual competition. When two males copulated with the same female, DNA fingerprinting showed that the male whose sexual encounter was signaled by a sexual CS was responsible for most of the resulting offspring. Sexual conditioning also reduced the first-male disadvantage in fertilization that occurs when two males copulate with the same female separated by several hours. Another significant finding was that sexual conditioning attenuated the usual drop in fertilization rate that occurs when the same male copulates with two females in succession.</p><p><strong>Conclusion: </strong>These results show that sexual conditioning increases the number of offspring that are produced in both isolated male-female encounters and in situations that involve two males copulating with the same female or one male copulating with more than one female.

Despite decades of progress, this incontrovertible truth is somehow lost in the far-too-often biologically deterministic interpretation of genetic, hormonal, and anatomical scientific research into the biological origins of sexual motivation. Simplistic and polarized arguments are used in the media by both sides of the seemingly endless debate over sexual orientation, equality, and human rights with such catch phrases as 'born gay' contrasted against attempts of \"reparative therapy\" or \"pray the gay away\".

Two experiments using intergroup evaluative tasks (Study 1: a gender-related groups evaluative task and Study 2: a minimal-related groups evaluative task) was conducted to determine whether motivation to strive for a positive social identity - a part of one's self-concept - drives attention toward affective stimuli. Using the P1 component of event-related brain potentials (ERPs) as a neural index of attention, we confirmed that attention bias toward negative stimuli is not mandatory but it can depend on a motivational focus on affective outcomes. Results showed that social identity-based motivation is likely to bias attention toward affectively incongruent information.

We believe the journal will appeal to a wide audience across several scientific specialties. In recent decades, considerable technical and theoretical advances have shed new light on psychological and neural processes. For example, in the area of neuroimaging techniques, it is now possible to explore the role of the brain in a wide variety of behaviours and paradigms (motor, perceptive, or cognitive). In the context of these new techniques, two important fields within cognitive neuroscience and psychology have started to emerge: (1) affective neurosciences that aim to explore the role of the brain in emotional and motivational information processing (Pankseep, 2003), and (2) social neurosciences that focus primarily on the role of the brain in social information processing (Insel & Fernald, 2004).
