Beliefs about female and male nonverbal communication

Participants (N= 441) rated from 1 to 10 how frequently or well they believed hypothetical women and men performed each of twenty nonverbal behaviors or skills. Women were believed to use more expressive and involved nonverbal behaviors than men, and to be more skilled at sending and receiving nonverbal messages. Men were believed to be louder and more interruptive, and to display more nervous, dysfluent behaviors. Ratings given to females by females were higher than were ratings in the other gender combinations for over half the variables, which may accurately describe female—female interaction. Perceived gender differences correlated positively with differences reported in observational studies, indicating that beliefs about nonverbal gender differences were generally accurate.

Beliefs about aggression among male and female prisoners

This study investigated instrumental and expressive beliefs about aggression, and their association with self-reported aggression, among male (N = 62) and female (N = 47) prisoners serving sentences in closed prisons in the North of England. Instrumental but not expressive beliefs were strongly correlated with measures of aggression. Expressive beliefs were significantly higher among females than males, but unlike previous findings, there were no significant sex differences in instrumental beliefs or in physical aggression. However, age was significantly negatively correlated with instrumental beliefs, physical aggression, anger and hostility. Those convicted for violent offences showed significantly higher scores for physical aggression and anger, but lower scores for expressive beliefs. The results provide both similarities and contrasts with previous findings for student samples. Aggr. Behav. 23:405–415, 1997. © 1997 Wiley-Liss, Inc.     

Fine motor skills and mathematics achievement in East Asian American and European American kindergartners and first graders

This study examined whether fine motor skills were related to the initial scores and growth rate of mathematics achievement in American kindergartners and first graders. Participants were 244 East Asian American and 9,816 European American children from the US‐based Early Childhood Longitudinal Study (ECLS‐K). To control sampling bias, two subsamples of European Americans were matched to the East Asian American sample by socio‐economic status or fine motor skills, using propensity score matching. Results showed that East Asian American children possessed more advanced mathematics achievement and fine motor skills. The construct of fine motor skills significantly predicted mathematics achievement over time, and further, it significantly mediated the relationship between ethnic group status and mathematics achievement.     

Adults' attitudes about assignments of household chores to male and female children

Data from a 1979 national sample of 3944 adults in the United States were analyzed for the purpose of identifying traditional and nontraditional sex role assignments of household chores. Among the eight chores observed, the proportion of the sample making nontraditional assignments ranged from a high of 90% to a low of 67%. With respect to explanations of traditional/nontraditional sex roles, observations included relationships between adults' age, sex, marital, family, and economic statuses, their assignments of chores to male and female children, and their attitudes about adults' sex roles. Males, older persons, and poor persons were more traditional in assigning chores than were females, the young, and the middle class. No differences were observed in chores assigned by married and single persons, or by married persons with and without children.An earlier version of this paper was presented at the 1988 annual conference of the Western Social Science Association.     

From response-set to prediction hypotheses: Rule acquisition among preschoolers and second graders

It was proposed that prediction hypotheses do not emerge full blown in the repertoire of the young child. Instead, the component units out of which predictions are consolidated (win-stay, lose-shift) are acquired independently and at different rates. The young child's behavior is at first dominated by response sets in which the win and lose components involve the same action (win-stay, lose-stay or win-shift, lose-shift). The components of response sets must be separated and coordinated with task-relevant information before appropriate components are consolidated to yield prediction hypotheses. A combination of learning-set and blank-trial procedures was used to evaluate this conception with preschoolers (mean CA = 4:1) and second graders (mean CA = 7:6). Results revealed that children of both age levels exhibited response patterns that corresponded to hypotheses in most of their probes (.89 to. 98). The striking finding was the relative weakness of win-stay on object cues at the outset of acquisition, particularly among the younger children. In contrast. lose-shift object was strong from the outset among children of both age levels. Once the two components (win-stay object, lose-shift object) were consolidated, the resulting scheme was durable, in that transfer to more complex problems was nearly perfect. Children who did not achieve criterion (in 70 problems) failed because they exhibited mostly position hypotheses and/or because the strength of win-stay object remained weak throughout all sessions.     

No sex difference in perceived competence of computer use among male and female college students in 2002

The present research examined sex differences in general computer knowledge and computer anxiety. Survey data about computer knowledge, comfort, and interest were collected from 697 students, 579 from a previous study in 2001 at three types of colleges (a four-year liberal arts college, a business college, or a community college). With few exceptions, no differences associated with sex were detected. Implications for the present findings are discussed.     

Beliefs about personality change and continuity

Lay conceptions of personality change and continuity were examined in a sample of 112 undergraduates. Participants rated their personal change over 5 years (past or future), the change they perceived to be normative over 10-year age spans between 15 and 65, their beliefs about whether personality is fixed or malleable (“lay theories”) and their beliefs about the causes of personality change and continuity. Beliefs about normative personality change generally corresponded to research evidence on adult trajectories of the Big Five factors, with some age bias, whereas recalled and anticipated personal change tended to be more positive than these norms. Participants tended to endorse environmental causes more for personality change than for continuity. Lay theories were not consistently associated with these causal beliefs, or with beliefs about personal and normative change.     

Temporal stability and predictive validity of self-assessed hand preference with first and second graders

The test-retest reliability and predictive validity of a five-item hand preference questionnaire (writing, drawing, throwing a baseball, brushing teeth, and cutting with scissors) were investigated in a sample of 80 children attending first and second grade. After 1 month, 81% of the second choices were the same as the first choices. There were interitem differences in the reliabilities of the five items. Writing and drawing hand exhibited the greatest degree of temporal stability. Writing hand was the one task which was significantly related to visual field bias as indexed by a face perception task.     

Gender differences in beliefs about the causes of male and female sexual desire

Little is known about the beliefs men and women have about the causes of sexual desire, despite the interpersonal and individual significance of those beliefs. Participants in this study received a definition of sexual desire and answered a set of free-response questions exploring their beliefs about the causal antecedents of male and female sexual desire. The results indicated that more women than men view female (and male) sexual desire as caused by external factors. In addition, both men and women believe that male and female sexual desire have different causes: intraindividual and erotic environmental factors are believed to cause male sexual desire, but interpersonal and romantic environmental factors are believed to cause female sexual desire. Although both men and women view physical attractiveness and overall personality as sexually desirable male and female characteristics, women, but not men, view femininity as a sexually desirable female characteristic, and men, but not women, view social and financial power or status as a sexually desirable male attribute.     

Attitudes held by members of the clergy about alcohol

Alcohol, tobacco and other drug abuse continue to cause major threats to the physiological, psychological, sociological and spiritual health of the nation. According to recent statistics, over 80% of the illegal drugs used by youth, both male and female, is marijuana, with cocaine, opium and their derivatives comprising at least 15% of the drugs used by youth. When considering the ill effects of drug abuse, it is the legal one, alcohol that is responsible for the greatest impact on society. While it remains imperative that allied health professionals understand the many ramifications of substance abuse, it is also critical that leaders of faith communities have the knowledge and skills to meet this challenge competently. Due to the relevance of ministries as a possible resource, the focus of this exploratory study is to assess the knowledge, skills and attitudes of clergy about substance use and abuse and to determine their confidence of clergy in assisting their congregation with need related to this area.     

Changes in syllabus tone affect warmth (but not competence) ratings of both male and female instructors

The syllabus is often the first meaningful piece of information that students receive about a course. Previous research has indicated that students form more positive impressions of a course instructor after reading a syllabus that has been manipulated to convey information in a friendly, rather than unfriendly, tone (Harnish and Bridges in Soc Psychol Educ 14:319–330, 2011). While a friendly syllabus leads to increased perceptions of instructor warmth and approachability, it is unclear from this previous research whether a friendly syllabus may also lead to decreases in the perceived competence of the instructor. Thus, we aimed to clarify whether changes in syllabus tone affect perceptions of instructor competency. We also wished to explore the possibility of gender bias affecting these syllabus-based impressions of instructors, and to examine whether differences in syllabus tone impact the impressions formed of male and female instructors in the same way. Participants read a friendly or unfriendly course syllabus from either a male, female, or gender-unspecified instructor. Regardless of instructor gender, participants receiving the friendly syllabus perceived the instructor as being more approachable, more caring, and more motivating, but not any more or less competent, compared to those receiving the unfriendly syllabus. While instructors will be relieved to know that efforts to appear friendly on a course syllabus do not appear to negatively impact student perceptions of instructor competence, more research is needed to examine the potential role of gender bias on students’ initial impressions of instructors.     

Response to Hanks and McDermott: Temporal Evolution of Beliefs and Beliefs about Temporal Evolution

This paper critically evaluates the celebrated paper of Hanks and McDermott on temporal projection, non-monotonic reasoning, and the frame problem. First I argue against their intuitions, and a fortiori, against their proposed solution. Next, I suggest how the solution they desire could be obtained, were they willing to represent the problem a bit differently.     

Pupillary response of male and female subjects to pupillary difference in male and female picture stimuli

On exposure to a series of identical pictures of a young man and a young woman differing only in size of the pupils of the eyes, the eyes of married Ss dilated more to the opposite sex pictures than to the like sex pictures, dilated most to the opposite sex picture with the larger pupils, and dilated least to the like sex picture with the larger pupils. Difficulties with neutral stimuli were noted and an improved method of assessing picture stimuli brightness was described.     

Self-evaluations of male and female managers

Two separate samples of males and females holding first-level management positions in United States organizations completed questionnaires which asked for self-evaluation on a number of job-related characteristics and for attributions of causality for successful and unsuccessful job experiences. In support of previous research, results indicated that males evaluated their performance more favorably than did women, and rated themselves as having more ability and greater intelligence. Men also saw ability as more responsible for their success than did women, but the sexes did not differ in attributions to luck, effort, or task. Implications for equal opportunity and potential for change are considered.     

Self-control in male and female rats

Eight male and 8 female Wistar rats were exposed to a discrete-trial procedure in which they chose between the presentation of a small (one pellet) or a large (three pellets) reinforcer. The delay to the small and large reinforcer was 6.0 s in the first condition of Experiment 1. Subjects consistently chose the large reinforcer. When the delay to the small reinforcer was decreased to 0.1 s in the next experimental condition, all subjects continued to choose the large 6.0-s delayed reinforcer. When the contingencies correlated with the two levers were reversed in the next experimental condition, the majority of subjects (5 males and 6 females) still chose the large delayed reinforcer over the small immediately presented reinforcer. The delay to the small reinforcer was maintained at 6.0 s, but the delay to the large reinforcer was varied among 9.0, 15.0, 24.0, and 36.0 s in Experiment 2, in which 4 males and 4 females participated. Most subjects consistently chose the large increasingly delayed reinforcer, although choice for the small 6.0-s delayed reinforcer developed in some females when the large reinforcer was delayed for 24.0 or 36.0 s. These choice patterns were not predicted from a literal application of a model that says choice should favor the alternative correlated with the higher (amount/delay) ratio.
