The role of modeling in prevention and extinction of phobic behaviour in cynomolgus monkeys (Macaca Fascicularis)

In previous studies surrogate reared cynomolgus monkeys have been shown to become phobic of an unprepared harmless object. In the present study an attempt was made to prevent the development of phobic behaviour in young monkeys and to extinguish avoidance behaviour in phobic monkeys. In the first experiment subjects were exposed to the object in company of their (surrogate) mothers which approached the object. In the second experiment phobic subjects were exposed to the object in company of non-phobic conspecifics which approached the object. The results of the first experiment show that modeling was unsuccessful in preventing the acquisition of phobia in the surrogate-reared monkeys but seemed successful in accelerating approach in the mother-reared subjects. The results of the second experiment show that during the modeling treatment the phobic subjects followed the model and approached the object. However, in post treatment tests all subjects but one relapsed into avoidance. The effect of modeling during treatment is interpreted in terms of coaclive facilitation.     

Infantile spasms: facial expression of affect before and after epilepsy surgery

This is a longitudinal study of facial expression of affect in 28 children with intractable infantile spasms who underwent epilepsy surgery. After a mean follow-up period of 1.8 years, there was a significant increase in positive affect, a significant decrease in neutral affect, and no change in negative affect during a nonverbal communication paradigm. These findings were unrelated to surgical (i. e., side of surgery, type of surgery) or seizure-related variables (i.e., seizure control, age at onset of illness, duration of illness, change in antiepileptic drugs). Comparison of affect in a subgroup of 16 patients with those of 32 normal subjects suggest a normal age-related increase in the use of positive affect. Both before and after surgery, the patients used the most positive affect while not communicating. They also used significantly more positive affect during while requesting objects or assistance rather than during social referencing. Intractable infantile spasms might be associated with reduction in the facial expression of positive affect and with impaired use during social communication.     

Vocational maturity and its relationship to Holland's theory of vocational choice

The major purpose of this study was to determine the relationship of vocational maturity with Holland's theory of vocational choice. Specifically, Holland's constructs of consistency, differentiation, and congruency, along with demographic factors of sex and age were examined in relation to vocational maturity. Subjects were students enrolled in high- and midconsistency level programs in two post-secondary institutions. Holland's Occupational Finder, Canadian Classification and Dictionary of Occupations, and Dictionary of Occupational Titles were used to determine program selection, and the Vocational Preference Inventory and the Career Maturity Inventory Attitude Scale were used to identify personality type and vocational maturity. Congruency and age related significantly to vocational maturity. Significant differences also occurred within both personality and program typologies.     

Relation‐based intervention with at‐risk mothers: Outcome in the second year of life

It has been shown that the UCLA home visiting/mother–infant group intervention made a significant positive impact during the child's first 2 years of life on two indices of the mother's support and on three areas of mother–child and child development: (1) The mother's responsiveness to the needs of her child and the related development of his or her security of attachment; (2) the mother's encouragement of her child's autonomy and the related development of his or her autonomy; and (3) the mother's encouragement of her child's task involvement and the related development of his or her task orientation. By child age 2 years, the mothers experiencing the intervention, in comparison with those that did not, also used verbally persuasive as opposed to coercive intrusive methods of control and their children responded more positively to these controls. Mothers who did not experience the help of the intervention had significantly more difficulty controlling their child if it was a boy as opposed to a girl. They used the least appropriate methods of control, and the boys responded more negatively to these controls. The nature of the development of the mother's use of appropriate controls and the child's response to that control was elucidated by determining on the total sample where 12‐month antecedents influenced the indices of control either independently of or in interaction with the intervention status. The child's endurance in the test situation was an independent predictor of mother‐appropriate control and the child's positive response to that control, while the absence of maternal intrusiveness further enhanced the impact of the intervention on that control. ©2001 Michigan Association for Infant Mental Health.     

Relationship‐based intervention with at‐risk mothers: Factors affecting variations in outcome

A previous group comparison had shown that in families experiencing the UCLA Family Development Project intervention as opposed to a group that did not, mothers became more responsive to the needs of their infants, and the infants were more secure in their attachment to their mothers. The present study asks whether variations in these outcomes following participation in a relationally based intervention are anticipated by maternal involvement in the intervention, partner support, personality dimensions, and mother–infant interactions that were assessed early in the intervention process. The sample consists of 46 mothers at risk for inadequate parenting who also were poor and generally lacked support. It was found that variations at 12 months of age in the child's secure response to separation, his or her expectation of being cared for (felt security), and the mother's responsiveness to need are anticipated by variations in the mother's 6‐ to 12‐month involvement in the home‐visiting intervention, the quality of her partner's support as measured at six months, and her own trust, ability to form stable relationships, and lack of self doubt. Parents who, at one month, were responsive to the needs of their more soothable babies were more likely to have secure children at 12 months, but these associations were not as robust as those summarized above. © 2000 Michigan Association for Infant Mental Health.     

Self-Identity and the Theory of Planned Behavior: A Useful Addition or an Unhelpful Artifice?1

Among the variables proposed as useful additions to the structure of the theory of planned behavior (Ajzen, 1991), there is evidence for the predictive usefulness of a measure of self-identity. In the study reported here, members of the general population in the United Kingdom (n= 235) completed a questionnaire addressing the consumption of a diet low in animal fats. The questionnaire was structured in terms of the TPB and contained additional variables that previous research has indicated to be useful predictors of intentions and behavior. A multiple regression of intentions (R²= .80) showed self-identification as a health-conscious consumer to have a predictive effect independent of the effects of these other variables. This effect was also found in replication studies.
