Expecting different categories at different locations and spatial selective attention

An experiment is reported testing the idea that spatial selective attention operates like the beam of a spotlight. Subjects made speeded orientation judgements to alphanumeric characters that could appear at an upper or lower display location. Letters tended (p = 0.8) to occur at one location, while digits tended to occur at the other. Alphanumeric category was pre-cued (p = 0.8). Response times were faster for cued than uncued items. For cued items subjects were faster at the likely location for a cued item. For uncued items this was reversed, with faster responding at the likely location for an uncued item. Hence, location selectivity reflected location probability for each category regardless of short-term expectancy concerning stimulus category. These data are incompatible with a simple spotlight view of spatial selective attention. Alternative explanations, including a modified two-stage spotlight model, were considered.     

The role of self-regulation in derogating attractive alternatives

The present research addresses the question of how romantically involved individuals are able to shield their ongoing romantic relationship from the temptation of attractive alternative partners. Specifically, two studies examined, and supported, the prediction that self-regulation promotes romantically involved individuals’ tendency to derogate attractive others as potential partners. Heterosexual participants responded to pictures of attractive and unattractive opposite-sex others by indicating their interest in these others as potential partners. In both studies the possibility for self-regulation exertion was manipulated (by means of self-regulation depletion in Study 1, and time-pressure in Study 2). When self-regulatory resources were relatively high, romantically involved participants exhibited less interest in attractive opposite-sex others than non-involved participants. However, when self-regulatory resources were low, interest in attractive opposite-sex others did not differ between romantically involved and non-involved participants.
