Relationship between Anxiety Sensitivity subscales and social fears

This study examined the relationship between social fears and the three subscales of the Anxiety Sensitivity Index (ASI) in a non‐clinical, student sample. In particular, the unique variance that the three ASI factors accounted for in social scrutiny fears, social interaction fears, and fear during a social challenge was investigated. Anxiety Sensitivity–Social Concern (AS‐Social Concern) was hypothesised to account for a significant proportion of the variance in social fears compared to the other two subscales. Seventy one university students completed a series of psychological‐based questionnaires and participated in a social challenge (videotaped speech task). Contrary to prediction, AS‐Social Concern did not account for a unique proportion of the variance in social fears, but AS‐Physical Concern and AS‐Mental Concern did account for unique variance in social fears. Results are interpreted in light of recent findings on the structure of ASI.     

Paternal behavior in the spiny mouse (Acomys cahirinus)

The responsiveness of adult male spiny mice (Acomys cahirinus) to both their own and alien precocial young was investigated. Paternal behavior was manifested primarily by the males huddling with their offspring and the coordination of pup attendance between adult males and females. With less than 2 days exposure to their own neonates, males were found to discriminate between their own and alien young. Experience plays an important role in the development of paternal behavior in spiny mice. Males who have never had pups of their own sniff and attack unfamiliar neonates more than males who have fathered pups. The adaptive significance of paternal investment in this uniquely precocial murid rodent was discussed.     

A second look at the impact of nontraditional vocational role models and curriculum on the vocational role preferences of kindergarten children

During a 10-week period 24 kindergarten children in a treatment group were exposed to nontraditional vocational role models and curricular materials, and a control group, consisting of 24 kindergarten children, was exposed to a curriculum unrelated to vocational or sex roles. Using a t test for related measures, the pretest and post-test scores were compared. The results were that the children in the treatment group were only slightly less traditional in their vocational role preferences at the end of the 10-week treatment. None of the t values were significant. These findings are compared to an earlier study in which one of the authors was involved and which used a similar, shorter term treatment (2 weeks). The results of this study are discussed in the context of L. Kohlberg's (E. Maccoby (Ed.), The Development of Sex Differences. Stanford, Calif.: Stanford Univ. Press, 1966.) Cognitive Developmental Theory of Sex Roles. Some possible implications for role-related education and further research are suggested.     

The impact of death on the family system

The impact of death on the family system creates a structural void that requires homeostatic adjustments. This paper describes bereavement adjustments in the family system. The author proposes that a family member may be stuck in one of the phases of grieving, which contributes to the homeostatic utilization of one or more of these adjustments. These homeostatic adjustments provide a matrix for abortive grief which may have transgenerational consequences. The author further proposes two stages of grieving in addition to those given by Bowlby (1979, pp. 82–83) and Parkes (1972); that of transformation and actualization. The family system or family-community system may hinder or help the bereaved family grieve, or make the homeostatic adjustment. Judeo-Christian values and rituals are described as relevant to this process.     

Age patterns in the development of children's gender-role stereotypes

This study examined the effect of the positive/negative quality of a gender-role stereotype on the age at which very young children are willing to associate the behavior with a member of a particular sex. The results indicate that, in comparison to 5- and 6-year olds, 4-year-old children are reluctant (1) to associate positive gender-role stereotypes with opposite-sex figures as well as (2) to accept negative stereotypes as characteristic of their own sex. In addition, a majority of the children in the sample associated with their own sex the gender-role stereotypes that are highly valued in the preschool and the school environment.     

Stimulus generalization of schedule-induced polydipsia

Five rats were exposed to an intradimensional discrimination by associating two tones of different frequency with the components of a multiple random-time 30-sec, extinction schedule of food presentation. After schedule-induced polydipsia developed and the intermittent schedule of food presentation established stable differential licking rates during the stimuli associated with the multiple schedule, a stimulus generalization test was conducted. When generalization testing was conducted by presenting stimuli that varied on the frequency dimension during the random-time 30-sec component of the multiple schedule, all five rats demonstrated moderately sloping symmetrical gradients. Thus, schedule-induced polydipsia can be brought under the control of stimuli other than the food pellet.     

Rationale for Individualizing Interventions to Promote Adjustment to the Nursing Home

This study was designed to determine whether certain variables were predictors of nursing home residents' membership in groups representing qualitative categories of nursing home adjustment. Responses of 186 residents to an open-ended question about how they handled the change to nursing home life were coded as very good, fair, or poor; an adjustment variable was created on the basis of this classification. Analysis of variance of random samples from each adjustment group showed that affect and social support varied significantly with adjustment. However, when discriminant analysis was applied, the three groups could not be differentiated using measure of affect, life satisfaction, social support, participation in the decisions leading to admission, nursing home satisfaction, or health. Based on the conclusion that adjustment to the nursing home is a unique experience for each individual, strategies were proposed for individualizing interventions to enable adjustment.     

An efficient,inexpensive food hopper for monitoring feeding habits of rats

An efficient food hopper designed for the constant monitoring of feeding patterns of rats is described. The apparatus is inexpensive and is designed to attach to standard rat housing cages.     

Dichotic and monotic interactions between speech and nonspeech sounds at different stimulus onset asynchronies

Subjects’ identification of stop-vowel “targets” was obtained under monotic and dichotic, forward and backward, masking conditions. Masks, or “challenges,” were another stop-vowel or one of three nonspeech sounds similar to parts of a stop-vowel. Backward masking was greater than forward in dichotic conditions. Forward masking predominated monotically. Relative degree of masking for different challenges suggested that dichotic effects were predicated on interference with processing of a complex temporal array of auditory “features” of the targets, prior to phonetic decoding but subsequent to basic auditory analysis. Monotic effects seemed best interpreted as dependent on relative spectrum levels of nearly simultaneous portions of the two signals.
