Life satisfaction and identity structure in late middle-aged men and women

A total of 32 retirement-age subjects (17 men and 15 women) provided information about their lives by rating each of their identities in terms of a list of self-generated features. They also rank-ordered their currently enacted identities in terms of time spent in each and completed a life-satisfaction questionnaire. The Identities X Features matrices were analyzed by algorithms that generated a hierarchical model of identity structure for each subject based on feature ratings. The hierarchical levels of identities were combined with time-spent rankings to obtain an index of personal style, a measure that reflected the unique organization of identities for each subject. Personal style indices were then correlated with life-satisfaction scores. Results confirmed the prediction that life satisfaction in this age group is a function of the amount of time spent in identities that give expression to multiple aspects of the self.     

A personal computer programmable sine-wave generator

A programmable sine-wave generator has been developed that permits microcomputer control of both discrete and continuous variations in the frequency and amplitude of auditory, visual, or vibrotactile stimuli. The function and design of the sine-wave generator as a peripheral to the Apple II/FIRST system are detailed. Moreover, adaptations of the basic sine-wave circuit are briefly described for interfacing it with other microcomputers (e.g., the IBM PC and compatibles), and for altering the waveform, range, and resolution of the output. Sample programs in Apple II/FIRST and Applesoft BASIC for controlling signal frequency and amplitude are used to illustrate the simplicity of programmable control. The sine-wave generator has many of the capabilities of commercially available ones, at a fraction of the cost.     

The effects of background visual roll stimulation on postural and manual control and self-motion perception

The effects of background visual roll stimulation on postural control, manual controlf andselfmotion perception were investigated in this study. In the main experiment, 8 subjects were exposed to wide field-of-view background scenes that were tilted and static, continuously rotating, or sinusoidally rotating at frequencies between 0.03 and 0.50 Hz, as well as a baseline condition. The subjects performed either a postural control task (maintain an upright stance) or a manual control task (keep an unstable central display horizontally level). Root-mean square (RMS) error in both the postural and manual control tasks was low in the static tilt condition and extremely high in response to continuous rotation. Although the phases of the postural and manual responses were highly similar, the power and RMS error generated by the sinusoidal visual background stimulation peaked at a lower frequency in the postural task. Vection ratings recorded at the end of the postural and manual trials somewhat paralleled tbafrequency tuning differences between tasks, which a subsequent experiment showed to be the result of the differential motion of the central display rather than the differential positioning of the subject. In general, these results show that the dynamic characteristics of visual orientation systems vary according to the specific motor and/or perceptual system investigated.     

Behavioural response home monitoring of good and insomniac sleepers

Can the fundamental differences in sleep structure known to differentiate good from insomniac sleepers (e.g., sleep length, sleep onset latency [SOL], number of sleep disruptions, etc.) be identified using a behavioural sleep/wake (S/W) monitor in the home? Sixteen women (8 good and 8 insomniac sleepers) enrolled in an introductory psychology course participated in a study of S/W patterns. They used a portable version of the Ogilvie and Wilkinson (1988) behavioural response (BR) system in their homes for 4 consecutive nights. Insomniacs had greater SOLs, less efficient sleep, and tended to have a greater number of arousals as compared with good sleepers. The data indicate that the behavioural system could be used as a diagnostic tool for in-home evaluations of disorders of initiating and maintaining sleep.     

Sex differences in responses to the stranger in the strange situation

Children are exposed to differences in adult interactive styles from an early age. The Ainsworth Strange Situation. designed as a standard measure to activate attachment behaviors in the young child, allows us to examine the child's reaction to individual differences in strangers' styles. In the present study, the effect of 11 different strangers was examined to determine if different stranger styles influenced the scoring of behavioral ratings of the child's behavior in the Strange Situation. Boys and girls reacted differently to the different strangers. Eighteen-month-old children showed more variations in their reactions to different interactional styles than did 12-month-olds. Boys showed more resistance and avoidance to strangers who used more direction and initiation. Girls did not react this way. The results are discussed in terms of the child's expectations of sex-determined styles of interaction learned from past social interactions.This research was supported by Grant MH 37911 to the senior author from the Behavioral Sciences Research Branch, Family Processes Division, NIMH, U.S. PHS and Grant HD 17571 from the National Institute of Child Health and Development.     

Male and female teachers: Do they treat boys and girls differently?

Forty experienced and inexperienced teachers, 20 male and 20 female, were observed during free play periods in preschool classes. Male teachers gave more favorable comment than female teachers, and also more physical affection. Male teachers also joined the play of the children more than female teachers. Female teachers interacted less than male teachers. Experienced teachers initiated behaviors, directed, gave information, asked and answered questions, and helped the child more than inexperienced teachers. Experienced teachers interacted more with boys and girls when they engaged in feminine-preferred activities, with no difference between male and female teachers in this regard. Inexperienced teachers of both sexes interacted more with boys engaging in masculine-preferred activities and girls engaging in feminine-preferred activities. It was suggested that the male stereotype and the school environment are less congruent than the female stereotype and school, and that experienced teachers encourage children to engage in school-type activities.This research was supported by a grant from the Office of Scientific and Scholarly Research, Graduate School, University of Oregon.

Sex and age differences in the sex-role stereotyping of third- and fifth-grade children

A four-part 85-item orally administered children's Sex-Role Expectations and Awareness Scale was developed. The four parts included measures of children's perceptions of (1) sex-associated behavior, (2) teacher expectations, (3) adult sex-role expectations, and (4) children's knowledge of the women's rights movement. The internally reliable scale was administered to 506 middle-class third- and fifth-grade children (259 females and 247 males) from eight schools in six states. Major results included the statistically significant findings that (1) although the absolute level of stereotyping was modest, males stereotyped significantly more often than females with regard to both male and female behavior traits and perceived teacher and adult sex-role expectation. (2) Third-grade students stereotyped more male behavior traits than fifth-grade students. (3) Females more often than males perceived teachers to expect traditional sex-role behavior from females. (4) Fifth-grade students knew more about the women's movement, but the absolute level of knowledge was quite low, with a comprehension rate around a third of the total number of items.     

The Bransford-Franks linear effect: Integration or artifact?

It was hypothesized that the Bransford-Franks linear effect is an artifact of the method of presentation of stimulus sentences and is unrelated to semantic processes. Ss were given sentences containing the same information in one of two ways. In a control condition, which was identical to the procedure used in earlier research, overlapping combinations of ideas were presented during learning and recognition; in an experimental condition, ideas were presented one at a time. Results demonstrated that one-idea sentences received significantly higher recognition confidence ratings in the experimental condition, thus supporting the artifact interpretation. It was proposed that Ss assign recognition confidence ratings based on the probability that a sentence containing a certain number of ideas could have occurred in acquisition.
