Social and emotional adjustment of infants and toddlers to a day care setting.

Infants five to thirty months old were observed for one week on entering a day care program, and again at the end of one month. Frequency of behaviors reflecting social and emotional adjustment were recorded. There was significant decreases in frequency of crying, sitting alone, and interacting with adults, while interactions with other children increased significantly. Results indicate that children of this age can adjust well, and quite rapidly, to a day care setting.

Factors in the modification by isolation of electroconvulsive shock-produced retrograde amnesia in the rat.

It has been demonstrated that placing rats in a sensory-restricted environment during the electronconvulsive shock- (ECS) retention interval following 1-trial appetitive learning will prevent or eliminate ECS-produced retrograde amnesia. The first study replicated this finding with a 1-trial aversive learning task, indicating that this effect is not task specific. The second study attempted to determine whether illumination or the restricted environment was the crucial factor in this penomenon. Rats placed in the light during the ECS-retention interval, whether restricted or in the colony, demonstrated retrograde amnesia after ECS. However, rats left in the dark during this interval demonstrated little, if any, retention deficit particularly if this condition was combined with sensory isolation. These studies further indicate that manipulation of the general environment of the animal after ECS can alter ECS-produced retention losses.

Menstrual cycle symptomatology: the role of social expectancy and experimental demand characteristics.

The purpose of this study was to examine the effects of experimental demand characteristics and social expectancies on the report and experience of presumed menstrual cycle-related moods and symptoms. Participating in the study were 18 healthy women with regular menstrual cycles who were randomly assigned to either a group told that menstrual cycle symptomatology was the focus of the study or a group to which no interest in menstrual cycle symptoms was communicated. Nine males were also included as a control group. Results indicated that women who were informed of the interest in menstrual cycle symptomatology reported significantly more negative psychologic and somatic symptoms at the premenstrual and menstrual phases than did the women and men not so informed. It appears, therefore, that the report of stereotypic menstrual cycle symptomatology is influenced by social expectancy and experimental demand characteristics.
