Emotional stimuli often attract attention, but at what cost to the processing of other stimuli? Given the potential costs, to what degree can people override emotion-based attentional biases? In Experiment 1, participants searched for a single target within a rapid serial visual presentation of pictures; an irrelevant, emotionally negative or neutral picture preceded the target by either two or...

The transition from vegetative to reproductive development establishes new growth patterns required for flowering. This switch is controlled by environmental and/or intrinsic developmental cues that converge at the shoot apical meristem (SAM). During this developmental transition, floral inductive signals cause the vegetative meristem to undergo morphological changes that are essential for flow...

Approaches to the post-retirement phase of life have undergone considerable change during the last decades. Until the 1970s most people worked until age 65; early exit was due to physical or mental impairment. Retirement marked the beginning of old age, a stage of life characterized by disengagement and loss (Covey, 1988) and by a role-less state (Burgess, 1960). Older persons needed to accept ...

The diagnosis of severe retardation offers little difficulty. The behavior of the infant in the office and the developmental history will establish the diagnosis. The imbecile and idiot (I.Q. below 50) are unable to do what the average child half their age can do. It takes them 2, 3, 4, or more years to learn what the normal infant learns in 1 year. Motor development is retarded and efforts at ...

Two pygmy chimpanzees (Pan paniscus) have spontaneously begun to use symbols to communicate with people. In contrast to common chimpanzees (Pan troglodytes) using the same communicative system, the pygmy chimpanzees did not need explicit training in order to form referential symbol-object associations. Instead, they acquired symbols by observing others use these symbols in daily communications ...

With the exception of post-exposure prophylaxis for reported rape, no preventive strategy addresses the choice disabled - those who might like to benefit from AIDS prevention but who are unable to do so because they do not have the power to make and to act on prevention decisions. In southern African countries, where one in every three has been forced to have sex by the age of 18 years, a very ...
