A model to study orienting responses in zebrafish,and applications towards the emotion–cognition interaction

Animal Cognition - Orienting responses (ORs) are whole-organism reflexes that are elicited by innocuous stimuli, and which decrease in magnitude after stimulus repetition. ORs represent relatively...     

Reconstructing Hymens or Constructing Sexual Inequality? Service Provision to Islamic Young Women Coping with the Demand to be a Virgin

In Islamic culture, there is an imperative demand that women should be virgins on their wedding night. Service providers in The Netherlands are increasingly confronted by Islamic young women who find themselves in serious difficulties because they are no longer virgins, and are about to enter a forced or arranged marriage. These young women report a diversity of problems such as loneliness, social isolation, depression, despair, suicidal feelings, identity problems and serious conflicts with parents. In this article we focus attention on the circumstances that can result in these types of difficulties, and also critically consider the kinds of help that young Islamic women are given. Attention is paid to the question of whether existing forms of service provision, especially surgical reconstruction of the hymen, take sexual and other inequalities into account.

Timing of the CS-US Interval by Pigeons in Trace and Delay Autoshaping

Evidence for timing during Pavlovian trace and delay conditioning trials was sought by exposing pigeons to differentially cued trial durations of 18, 24, and 60 sec. For a delay group, one of three visual patterns (CSs) was presented on a key for the entire trial; for a trace group, each CS was 12 sec in duration, creating trace gaps of 6, 12, or 48 sec. Intertrial interval duration was 48 sec. The most informative data were provided by measures of time spent proximal to the CS (proximity). Stimulus control was evident in that proximity was inversely related to trial duration for both groups. Evidence for timing was obtained from the relation of relative proximity during each CS to relative elapsed trial time for individual birds. The obtained superposition of the three functions for each bird is consistent with a scalar timing process and implies that subjects learned the temporal relation between each CS and the unconditioned stimulus. Associative status of the CSs differed between groups and among CS-US intervals, as reflected in proximity data during a higher-order test in which the CSs served as reinforcers. The results are consistent with a two-dimensional model of Pavlovian conditioning according to which the associative strength accruing to a CS is orthogonal to the temporal information encoded for that stimulus.
