Evaluation of sex-typed tasks by black men and women

Two studies examined the relationship of sex of subject, sex-typing of tasks, and prior task experience on self-confidence ratings of Black men and women. In both investigations, women's self-confidence tended to vary as a function of task type, while men's self-confidence remained relatively stable across all tasks. Prior experience with the task was highly correlated with self-confidence ratings for men and women and moderated the effects. The variations in the findings of Studies I and II and implications for future research are discussed.Portions of this study were reported at the Eastern Psychological Association Convention, 1983.     

Generalization of relative competence mediating conformity across differing tasks

Subject correctness and group agreement were initially varied for college subjects performing a multiple-choice informational task (Canadian Knowledge Inventory). On a subsequent perceptual task (Raven's Standard Progressive Matrices), the dependent variable of conformity was assessed to examine generalization of relative competence formed on the informational task. It was seen that: (1) Those who perceived themselves to be less competent than the group on the first task exhibited the greatest level of conformity on the second task, thus replicating previous research on perceived relative competence as a determinant of conformity; (2) suspicion reduced conformity.     

Direction of human motor responses by men and women to aversive stimulation

The frequency of extensions and flexions of the arms of 12 men and 12 women (ages 20-30 years) responding to a neutral tone or to an electric shock was recorded. Subjects had to choose between pushing or pulling a lever upon receipt of an acoustic signal which was paired or unpaired with an electric shock. They were instructed to perform either long duration movements, allowing for on-line control of the execution, or short duration movements with prior specification of amplitude. Regardless of duration of movements, the aversive signal increased the frequency of extensions and intraindividual variability of choices of the men but decreased the frequency of extensions and intraindividual variability of choices of the women. These findings show that stimuli such as pain or fear automatically elicit patterns of terminal motor states corresponding to fight or flight, initiating processes of preparation of spatially oriented movements which are automatic and sex-typed and impair the use of the terminal cues for simultaneous preprogrammed voluntary movements.     

A mechanism for error detection in speeded response time tasks

The concept of error detection plays a central role in theories of executive control. In this article, the authors present a mechanism that can rapidly detect errors in speeded response time tasks. This error monitor assigns values to the output of cognitive processes involved in stimulus categorization and response generation and detects errors by identifying states of the system associated with negative value. The mechanism is formalized in a computational model based on a recent theoretical framework for understanding error processing in humans (C. B. Holroyd & M. G. H. Coles, 2002). The model is used to simulate behavioral and event-related brain potential data in a speeded response time task, and the results of the simulation are compared with empirical data.     

Androstadienone in motor reactions of men and women toward angry faces

The endogenous compound androstadienone modulating the evaluation of others and activating the human fear system was hypothesized in terms of processing socially relevant cues by regulating responses to angry faces. Androstadienone was investigated in association with arm movements of 62 participants (30 women) in response to happy and angry facial expressions. Volunteers pushed away or pulled toward them a joystick as fast as possible on seeing either an angry or a happy cartoon face on a computer screen. This task was repeated twice: once during exposure to androstadienone masked with clove oil and once to clove oil only. In the former condition participants' reaction speed was accelerated, especially when reacting to angry faces. This observation may indicate an androstadienone-related activation of the fear system leading to faster responses to threat signals, assuming an enhanced allocation of attentional resources toward threat-related social cues.     

Willingness to date across race: differences among gay and heterosexual men and women

Willingness to date members of other races was examined among 200 men with same-sex dating preference (n = 100) and opposite-sex dating preference (n = 100), and 200 women with same-sex dating preference (n = 100) and opposite-sex dating preference (n = 100) who were randomly selected from an Internet dating web site. Overall, results indicated a greater willingness among gay participants than heterosexual participants to date people of other races. A 2 (Sex) x 2 (Sexual Orientation) analysis of variance showed an interaction, with lesbian women more willing to date other races than gay men, while among heterosexual participants men were more willing than women to date other races. The role of mate selection theory, and the importance of the status afforded various races in U.S. society, were applied to interpret people's willingness to date other races.     

Generalization of mental health across life sectors

Abstract.— Questionnaire data on mental health in three life areas (work, family, and leisure) were analysed by ANOVA together with estimation of the magnitudes of different effects. The Ss were 60 employed women with varied marital status. About 55% of mental health variation was explained by the generalization model and 4% by the person by life area interaction. It was suggested that analysis of variance components is useful in comparing corresponding effects in different groups of subjects. Some limitations of cross-sectional research strategy were discussed, stressing the need for other strategies in research on the relation between mental health in different life areas.     

Modeling behavioral measures of error detection in choice tasks: response monitoring versus conflict monitoring

The present study investigated the mechanisms underlying error detection in the error signaling response. The authors tested between a response monitoring account and a conflict monitoring account. By implementing each account within the neural network model of N. Yeung, M. M. Botvinick, and J. D. Cohen (2004), they demonstrated that both accounts make different predictions as to how error signaling performance is influenced by varying the participants' response criterion. These predictions were tested in an experiment using the Eriksen-flanker task. The qualitative pattern as well as a model fit favored the response monitoring account, which states that error detection is mediated by detecting internal error corrections.     

Observer recorder error as affected by different tasks and different expectancy inducements

Four experiments were designed to investigate the effects of systematic observer/recorder error on experimental results where experimenters had been induced to expect certain results. In the first experiment, experimenters were induced to expect certain outcomes for three different tasks. No observer error nor experimenter-effects were observed. Postexperimental interviews indicated some suspiciousness as well as failure to understand the hypotheses on the part of experimenters. In the second experiment expectancies were induced in observers who did not act as experimenters. No observer effects were noted, and again postexperimental interviews indicated manipulation failure. In the third experiment experimenters were asked to attempt to influence subjects' responses. Three tasks were used, but in two of these tasks observer error was controlled rather than measured. No differences in subjects' responses were noted for any of the measures. However, significant observer/recorder error was noted for both male and female experimenters in the task where such error was measurable. In the fourth experiment experimenters were again asked to influence subjects' responses. For the two tasks used observer error was measured. A predicted Task × Observer Error Interaction was obtained. Again, no differences in subjects' responses were noted.     

Depression Anxiety Stress Scales: Factor structure and differential item functioning across women and men

This study examined the factor structure, and differential item functioning of the Depression Anxiety Stress Scales (DASS; Lovibond & Lovibond, 1995) across sex. The DASS was completed by 201 women and 165 men from the general community. Confirmatory factor analysis (CFA) indicated support for the original 3-factor oblique model (factors for depression, anxiety and stress). There was however more support for a bifactor model, with four orthogonal factors: a general factor on which all the depression, anxiety and stress items load, and specific independent factors for depression, anxiety and stress items. None of the DASS items showed DIF. The practical, theoretical, research and clinical implications of the findings are discussed.     

Consistency and error in motor performance

Two response measures that described the consistency and accuracy of motor performance were investigated. A pursuit tracking task was used as the vehicle whereby changes in perceptual motor performance could be monitored over several learning trials. The intra-individual variability of a subject's tracking response was compared to the root mean squared error that was accumulated during each block of trials. Whereas both response measures were sensitive to the changes in performance that occured as a result of practice, neither could be considered sufficiently informative as to be used as a sole indicator of skill acquisition. It appears that both consistency and error measures are needed to describe the subjects' performance as they acquire a perceptual motor skill.     

Investigating invariance in the factorial structure of the anxiety sensitivity index across adult men and women

The Anxiety Sensitivity Index (ASI; Peterson & Reiss, 1992) is one of the most widely used measures of the fear of anxiety-related sensations. Important gender differences also seem to exist in that women report higher levels of anxiety sensitivity than men. The primary objective of this study was to determine whether an equivalent factorial structure exists for the ASI among nonclinical adult men and women. In Study 1 (568 women; 251 men), the 2-factor (Fear of Cardiopulmonary Sensations and Fear of Mental Catastrophe), 10-item version of the ASI reported by Schmidt and Joiner (2002) provided the best fit to the data for both men and women. Using this model, Study 2 (503 women, 255 men) examined whether the factorial structure of the 10-item ASI was invariant for men and women. Noninvariance was found for one item on the Fear of Mental Catastrophe subscale (Item 15="When I am nervous, I worry that I might be mentally ill"). The implications of this are that this item should be dropped if an equivalent factor structure is to be assumed between men and women.

Individual differences within and across attentional blink tasks revisited

When the second of two targets (T2) is presented in close temporal proximity (within 200–500 ms) to the first (T1), the accuracy for reporting T2 is reduced relative to when the targets are separated by longer durations; this effect is known as the attentional blink (AB). Two recent studies have shown that individual differences in the magnitudes of the AB are stable both within a single testing session and over time. While one study found a large positive correlation between AB magnitudes when there was an attentional-set/task switch between T1 and T2 and when there was not, the other study found no relationship between the switch and no-switch paradigms. The present study was conducted to clarify this discrepancy by examining the reliability of, and relationships among, individual differences in AB performance on five different versions of the standard dual-target RSVP paradigm, three of which involved an attentional-set/task switch between T1 and T2, and two of which did not. Participants completed all five paradigms, and then returned 7–10 days later to again complete the same paradigms. The performance on all five versions was reliable both within and across testing sessions, demonstrating again that individual differences in AB performance are stable over time. In addition, all five AB versions were significantly intercorrelated, although the strengths of the relationships differed depending on the extent to which the T1 and T2 attentional sets/tasks overlapped. These findings provide evidence that multiple distinct dual-target RSVP tasks do share underlying variability, providing support for the use of different versions of the paradigm in the literature.     

The generalizability of story grammar training across setting and tasks

Reading achievement depends in part on children's ability to employ strategies to monitor their comprehension, that is on children's use of metacognitive skills. An experimental intervention program created to foster such skills was evaluated. The story grammar training was designed to increase both strategic reading behavior and explicit, observable comprehension monitoring. Fourth-grade (N = 20) and fifth-grade (N = 16) children were randomly assigned to experimental and control groups. Maintenance was examined using free and probed oral recall, notetaking, and summarization of brief narrative and expository texts. Generalization was assessed through free and probed written recall of a lengthy text, which required both strategic reading and summarization skills for adequate comprehension. Skill acquisition was clearly demonstrated; trained readers were able to recall and summarize passages better than untrained readers. The evidence for generalization was more equivocal: although trained readers' free recall was significantly better than that of untrained readers, their probed recall was not. Provision of metacognitive skills that promote active comprehension monitoring, then, appears to provide children with the tools needed for independent reading. Programs designed to provide such skills may aid efforts to prevent reading failure.
