Development of tactile patterns in relation to age, sex, and race.

Two observers recorded the frequency of touch between male and female and Black and White kindergartners and 1st-6th graders in school cafeteria lines. In same-sex pairs, boys and girls in White and in integrated schools showed a reduction in frequency of touch from kindergarten to 6th grade, but in the Black school, no reduction was observed. Only 1 cross-racial hand-to-hand touch was observed. Data show that social norms related to sexual and racial interaction are the most important factors in the development of touch and interaction distance.

Sleep in relation to age, sex, and chronotype in Japanese workers

The Morningness-Eveningness Questionnaire and Life Habits Inventory were administered to 622 Japanese workers matched for sex and age. We investigated the distributions of the scores on the Morningness-Eveningness Questionnaire and sleep-wake habits by age and sex. Subjects were classified into five age groups and three chronotypes. The distributions and mean scores on the questionnaire advanced slightly toward the Morning type from the young to the aged group. The habitual bedtimes and waking times were significantly earlier in all the chronotypes from the young to the aged group, and the preferred bedtimes and waking times were also clearly earlier from the young to the aged group. The length of sleep was shorter for the Evening than the Morning types, especially in the group below 24 yr. The differences in habitual and preferred sleep length were greater than 1 hour for all age groups, especially the two groups under 34 yr. The number of awakenings during night sleep increased from the young to the aged group for all chronotypes. The older Evening type tended more toward frequent napping and longer naptime. The variabilities of bedtime and sleep length were larger for the young and Evening type than for the old group and Morning types. Further, the mood upon waking and satisfaction with sleep length were better in the aged Evening type than the young Morning type. The women under 44 yr. woke up earlier than the men of the same age, and the women of the 35-54 yr. groups had a shorter length of sleep than others. These may be related to childcare and housework. These results indicated that the phase of circadian rhythms had moved forward from the young to the aged group, and the individual's rhythm, of those that were aged Morning types, showed better agreement with sleep-wake rhythms than did others.     

Cephalic measures in normal pre-school children 3 to 7-years of age

In a study designed to determine standards for the Developmental Neurological Examination (DNE) several measures of the head were also recorded. The study consisted in the examination of 200 children, half from each sex, 40 from each age group (3 to 7-years of age). These children were selected among 755 normal pre-school-age children, living in the city of S?o Paulo, Brazil). The criteria for selection were both anamnestic and clinic. The following measures of the head were recorded: cephalic perimeter, biauricular and antero-posterior distances (Diament, 1967). A new cephalic index (nCI) was also determined (Diament, 1968). This index is useful in detecting changes in head shape mainly in cases of precocious cranioestenosis (Diament, 1968; Facure, 1972). The statistical analysis consisted in determining means and standard errors for each measure. For the new cephalic index it was shown through the Kruskal-Wallis test that there were no significant difference between age and sex. Therefore we considered all groups together to find out the tolerance region for the new index which turned out to be given by the interval: 0.848-1.002. This result is based in 186 cases since 14 were excluded because of some problems in the recording process. Therefore we expect with a conficence of 95% that the above interval covers 90% of the population, in the 3 to 7 years age-groups independently of sex.     

VIP neurons in the human SCN in relation to sex, age, and Alzheimer's disease

The brains of 46 control subjects and 21 Alzheimer's disease (AD) patients were studied to determine whether there are age-related or AD-related changes in the vasoactive intestinal polypeptide (VIP) neuron population of the human suprachiasmatic nucleus (SCN). The number of VIP expressing neurons in the SCN of females, ranging in age from 10-91 years, did not change during normal aging. In males, however, the number of VIP neurons in the SCN was highest in the young subjects (10-40 years of age), after which, a dramatic decrease occurred in middle-aged subjects. This resulted in an age-dependent sex difference in the VIP cell population of the SCN: young males had twice as many VIP expressing SCN neurons as young females, whereas in the middle-aged groups, the females had twice as many VIP SCN neurons as the males. A significant decrease in the number of VIP expressing neurons in the SCN was found in female presenile AD patients, i.e., those younger than 65 years.     

Types of stressful situations and their relation to trait anxiety and sex.

Based on C. D. Spielberger's (see 40:11) proposal that trait anxiety scores reflect a predisposition to respond with heightened state anxiety to situations involving the possibility of failure or loss of self-esteem, it was predicted that Ss who indicated that they were high in A-trait would report anticipating greater fears in these situations and not in situations involving physical pain or danger. 228 undergraduates rated 40 situations according to the degree of apprehension that they thought they might feel if in that situation. The 40 items were intercorrelated and factor analyzed. Of the 4 factors obtained, the 3 factors associated with failure correlated significantly with a measure of trait anxiety, while the 4th factor, involving pain and danger, did not, supporting Spielberger's hypothesis. Sex differences were found only for the pain-danger factor. (25 ref.) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Person-specific paths of cognitive decline in Alzheimer's disease and their relation to age.

Change in global and specific measures of cognitive function was studied in a cohort of 410 persons with Alzheimer's disease. Persons completed up to 5 annual evaluations; follow-up participation among survivors exceeded 90%. Average annual decline was 0.57 standard score units (95% confidence interval [CI]: -0.51 to -0.62) on a composite measure based on 17 individual tests and 3.26 points (95% CI: -3.06 to -3.46) on the Mini-Mental State Examination, but substantial heterogeneity was apparent. On both global and specific measures, rate of cognitive decline was reduced in older persons compared with younger persons. A similar effect was observed for estimated age of disease onset. The effect of age was approximately linear and was not attributable to education, sex, race, other conditions that impair cognition, or mortality. The results indicate that person-specific paths of cognitive decline in Alzheimers disease vary substantially and suggest that in clinical settings some of this variability is related to age.

Encoding and retrieval operations in relation to age.

In 2 experiments, the memory performance of a total of 40 young (mean age 18 yrs) and 40 elderly (mean age 75 yrs) Ss was compared in a procedure that allowed testing of the target words twice, first for recognition and then for cued recall. Conventional analyses of the recall and recognition data gave results that echoed previous findings that (a) significant age differences were found in recall but not in recognition, and (b) the recall differences were minimized when the target items were recalled in the context of cues highly related to the target items. In accordance with contemporary theoretical conceptions of memory, a feasible interpretation of these results is that memory loss is due to a retrieval deficit. However, further analyses showed that both young and older Ss failed to recognize many words that they subsequently recalled, suggesting that some caution is necessary in interpreting overall recall and recognition memory performance. Possible differences in encoding and retrieval processes as a function of age are discussed. (18 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Relationship of age, age at onset, and sex to depression in older adults

The authors investigated the relationships among factors of age, age at onset, and sex in depressed older adults. A group of 96 outpatients (mean age, 60) diagnosed with late-(LOD) and early-onset (EOD) major depression were assessed for severity of depression and underwent magnetic resonance imaging (MRI). The MRI scans were rated for severity of white-matter hyperintensities (WMH) and ventricle-to-brain ratio (VBR). LOD was associated with increased amounts of WMH, larger VBR, and history of hypertension. Men were more severely depressed than women, with higher rates of neurovegetative signs and history of smoking. Age correlated with increased VBR and WMH, history of hypertension, history of percipitants for the current episode, and lack of social support. Results suggest that a subgroup of men may be more at risk for LOD associated with WMH and that sex and age at onset need to be considered in future studies.     

Dynamic visual acuity as related to age, sex, and static acuity.

What effects ability to follow visually a moving target? How about static acuity? Using equipment, including slides, to study static acuity, with 236 Ss, it was concluded that this does not predict it. "The exact nature of those factors other than static acuity that influence dynamic acuity are not yet known, but it is probable that they involve the efficiency of the entire oculo-motor system."

Hand function related to age and sex

After adapting Jebssen's Test of Hand Function to Australian conditions, this study investigated his claim of no significant difference in hand performance among participants younger than 60 years, and determined whether age might be a factor when associated with sex. The method was to test 383 subjects of both sexes in 6 age groups. A 2-factor analysis with age and sex as factors yielded significant differences (p less than 0.01) for "grip strength" "manipulating small objects," and "moving large heavy objects," and indications of significance (p less than 0.05) for "card turning" and "moving large light objects." The sex factor showed males to be significantly better "grip strength," in "moving large heavy objects," and "large light objects," except in the 66-99 age interval where females were significantly better on teh last 2 variables. Females performed better on "writing" and were generally better in "manipulating small objects." These results suggest that the one set of norms given by Jebsen for 60 years and less for each sex, should be replaced by 5 or more, even though the differences were quite small when standard deviations were considered.     

Menopausal age in relation to smoking

A population study of women revealed more smokers among 50-year-old postmenopausal women than among women of the same age who still menstruated. The difference was statistically significant. The postmenopausal smokers had on average smoked as long as or longer than the smokers who still menstruated. The higher number of smokers among postmenopausal women could thus not be explained by these women starting to smoke in connection with the menopause. Non-smoking women were on average heavier than smoking women. Previous studies indicate that an increased amount of adipose tissue might delay the menopausal age. It is therefore possible that the difference in menopausal age between smoking and non-smoking women might be explained either by a delayed menopause in non-smoking women due to an increased amount of adipose tissue in these women, or by a precocious menopause in smokers due to toxic effects from smoking. Probably both factors are of importance, but our results indicate that smoking per se is the main factor. The increased number of smokers among women with precocious menopause can probably explain part of the overrepresentation of women with precocious menopause among those who have myocardial infarction.     

Touch interactions in junior high students in relation to sex and race.

Noted the incidence of touching among 321 White females, 241 White males, 205 Black females, and 198 Black males in cafeteria lines in 7 Kansas City junior high schools. Data were analyzed by sex and race and compared to behavior seen in primary school Ss in an earlier study (F. Willis and G. Hoffman, 1975). It was found that about half as much touching occurred among these groups compared to the younger children. Touch was most likely between Black–Black combinations and least likely between White–Black. Black females were significantly more likely to touch others than were White females.

Speed and coding effects in relation to age and ability level.

Studied 2 dimensions measured by the Digit Symbol subtest of the WAIS—speed and cognition—in relation to age. Data from 20–30 and 65–75 yr olds of average and high verbal ability are congruent with previous findings that both the speed and coding components are important factors contributing to a substantial age decline in Digit Symbol performance, but raise questions about the effects of Ss' educational experience.

The influence of age and sex on responsiveness to babies.

Interest in babies was assessed in 32 8–9 yr olds and 32 14–15 yr olds by 6-sec time sampling of waiting room behaviors in the presence of a live baby and by reactions to pictures of babies vs other objects. Age conferred mode differences in behavioral responsivity: Adolescents made more proximal bids, 8–9 yr olds more distal bids. Males and females differed in amount of behavioral and perceptual baby interest, with girls more responsive than boys. Sex differences were virtually absent among 8–9 yr olds but emerged during adolescence. Interpretations in terms of increased salience of sex-role stereotypes during adolescence are offered.

Countercontrol treatment of sleep-maintenance insomnia in relation to age.

Administered countercontrol behavioral therapy for sleep-maintenance insomnia to 34 insomniacs (aged 35–78 yrs) in small groups. 22 Ss received immediate and 12 received delayed treatment. Three self-report measures of sleep disruption were collected on daily sleep diaries at baseline, termination of treatment, 1-mo follow-up, and 12-mo follow-up. Although amount of time awake at night was correlated with age, response to treatment was not. Even though older Ss experienced more time awake after sleep onset prior to treatment, they were able to profit from therapy as well as the younger insomniacs. Countercontrol therapy reduced the sleep complaint for the total group by about 30% at the end of treatment, with gradual improvement continuing through a 4-wk follow-up. It is suggested, however, that sleep-maintenance insomnia may be more difficult to treat than sleep-onset problems. (21 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Chiasmata, meiotic univalents, and age in relation to aneuploid imbalance in mice

Chiamata were counted and paired and unpaired configurations at first meiotic division and chromosome errors at second meiotic division were assessed at different ages in males and females of two strains of laboratory mice. In the females a decrease of chiasma frequency and an increase of univalents at first meiotic metaphase (MI) were confirmed. In the males, diakineses had higher chiasma frequencies (in the range of the female MIs) and fewer univalents than the MIs had. In these male cells there was no decrease of chiasmata or increase of autosomal univalents with age, and there were some interstrain differences. In the older females there was no parallelism between the frequencies of univalents at MI and the chromosome errors that could be identified at second meiotic division; these were fewer than might be expected on the assumption that all the univalents were true univalents. The relevance of this finding to the question of the nature of most of the univalents observed at first meiotic division in aged female mice is discussed.     

Sensation seeking in England and America: Cross-cultural, age, and sex comparisons.

Compared the factor structure of the Sensation-Seeking Scale (SSS) in English and American samples, and constructed a new form of the SSS, applicable to both groups. The English Ss consisted of 254 males and 639 females from the Maudsley Twin Register, ages 15–70 yrs. The American sample included 97 male and female undergraduates. Three of the 4 factors showed good cross-national and cross-sex reliability (i.e., significant and reasonably high resemblance between the 4 national and sex symbols). English and American males did not differ on the total SSS score, but American females scored higher than English females. Males in both countries scored higher than females on the total SSS score and on the Thrill and Adventure-Seeking and Disinhibition subscales. Significant age declines occurred for both sexes, particularly on Thrill and Adventure Seeking and Disinhibition. (24 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Memory for spatial layouts in relation to age and schema typicality.

The hypothesis that prior experience, specifically a knowledge-based schema for typical house layouts, can compensate for age declines in spatial memory was evaluated in 4 experiments. Old and young adults explored and subsequently recalled house layouts presented 1 room at a time on a computer screen. The findings failed to support the compensation hypothesis in that schema-relevant layouts facilitated recall equivalently for the 2 age groups. Violation of a typical house schema had a more negative effect on recall of the older group. Individual differences in spatial visualization ability explained much of the age difference in performance but not the effects of schema manipulations. It was concluded that there is age invariance in the facilitatory effects of relevant prior knowledge on spatial memory but an age-related decrease in the ability to inhibit irrelevant prior knowledge.

Judgments of chronological age: Adult age and sex differences.

62 male and 137 female undergraduates and 76 male and 93 female Ss (mean age = 71.3 and 71.6 yrs, respectively) judged the ages of males and females portrayed in sets of 27 photographs. Results demonstrate the operation of judgmental assimilation and contrast principles in determinations of chronological age, with females exhibiting greater extremity of judgments than males.

Three experiential practices and their relation to psychoanalysis.

In this article, the author compares three experiential practices: the use of psychoanalytic evenly suspended attention, the adoption of the philosophical attitude of the phenomenological reduction, and the practice of Buddhist bare attention. Convergences and differences between these practices with respect to their uses, aims, and attendant qualities of consciousness are noted. Samples of patient-therapist interaction are used to demonstrate how these three experiential sets can operate synergistically in the course of psychoanalytic therapy.
