Factorial complexity and validity of the Sahin–Francis Attitude toward Islam Scale among Pakistani university students

English‐speaking Pakistani university students responded to the Sahin–Francis Attitude toward Islam Scale, along with other religious measures and a social desirability scale. This scale was multidimensional. Correlations with religious measures confirmed its validity and were not explained by a social desirability response set. These data identified the Sahin–Francis Scale as a useful measure for studying Muslim attitudes within an Islamic society.     

Evolutionary autonomous agents and the naturalization of phenomenology

The phenomenological goal of grounding the content of conceptual thought in the background understanding of everyday, skillful coping was approached using evolutionary autonomous agent (EAA) methodology. The behavior of an EAA evolved to perform a specified motor task was identified with skillful coping. Changes in the dynamics of the EAA controller occurred when the EAA encountered an unexpected obstacle with loss of longer time scale components in its hierarchical temporal organization. These temporal changes are consistent with the phenomenological changes which we experience with breakdown during equipment use with our adoption of a more immediate, determinate stance. Since this latter experience is the basis of conceptual thought, the EAA paradigm goes some way in providing a naturalized explanation for the grounding of the content of conceptual thought in everyday, skillful coping in a manner that is physiologically plausible and phenomenologically accurate.     

Influence of Zn incorporation on the microstructural and magnetic properties of La0.67Sr0.33Mn1−xZnxO3 nanoparticles synthesised by the sol–gel method

Perovskite manganite nanoparticles with the chemical formula La_0.67Sr_0.33Mn_1?xZn_xO₃ (x = 0, 0.1 and 0.2) were prepared by the sol–gel process and the influence of Zn substitution on their microstructural and magnetic properties studied in detail. X-ray diffractometry (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM) were employed for crystal structure determination and microstructural analysis. The results of XRD analysis confirmed the polycrystalline nature and rhombohedral crystal structure with space group R(-3c) for all compositions. SEM micrographs of the samples revealed an agglomeration/well-connected appearance of the particles. The composition and uniform distribution of all the elements were established by energy-dispersive spectroscopy. TEM images clearly confirmed an almost spherical shape of the nanoparticles with an average particle size of about 11, 14 and 13 nm for the 0, 10 and 20% Zn-doped samples, respectively. The magnetic behaviour of the nanoparticles was studied at room temperature with a vibrating sample magnetometer (VSM) up to a field of 1.8 Tesla. These measurements established a superparamagnetic nature with a variation in the saturation magnetization (M_s) with Zn content.     

How Collective Participation Impacts Social Identity: A Longitudinal Study from India

A key issue for political psychology concerns the processes whereby people come to invest psychologically in socially and politically significant group identities. Since Durkheim, it has been assumed that participation in group‐relevant collective events increases one's investment in such group identities. However, little empirical research explicitly addresses this or the processes involved. We investigated these issues in a longitudinal questionnaire study conducted at one of the world's largest collective events—a month‐long Hindu festival in north India (the Magh Mela). Data gathered from pilgrims and comparable others who did not attend the event show that one month after the event, those who had participated (but not the controls) exhibited heightened social identification as a Hindu and increased frequency of prayer rituals. Data gathered from pilgrims during the festival predicted these outcomes. Specifically, perceptions of sharing a common identity with other pilgrims and of being able to enact one's social identity in this event helped predict changes in participants' identification and behavior. The wider significance of these data for political psychology is discussed.     

A multitrait-multimethod analysis of the preschool behavior questionnaire

The Preschool Behavior Questionnaire is a teacher rating instrument yielding a total score reflecting overall level of adjustment and three subscale scores labeled Hostile/Aggressive, Anxious/Fearful, and Hyperactive/Distractible. This study assessed the convergent and discriminant validity of this teacher rating measure against two alternative measures within a multitrait-multimethod analysis. The results supported the construct validity of the Hostile/Aggressive and Anxious/Fearful scores as well as the overall score. There was, however, no support for the validity of the Hyperactive/Distractible score.This research was supported, in part, by a grant from the Pickering Foundation. The authors would like to thank Maria Bhaneja for her help in the collection and coding of data. Thanks are also extended to the teachers and children who participated in the study.     

Your Sexism Predicts My Sexism: Perceptions of Men’s (but not Women’s) Sexism Affects One’s Own Sexism Over Time

The effects of perceived normative (societal) levels of benevolent (BS) and hostile sexism (HS) on one’s own sexist attitudes were examined over a four-month period in an undergraduate New Zealand sample (76 women, 26 men). Perceptions of normative levels of men’s BS produced longitudinal change in one’s own BS, and this effect was invariant across gender. However, contrary to previous research suggesting that women endorse BS when men are high in HS for its protective benefits, women instead expressed subjectively positive paternalistic attitudes toward their gender to the extent that they perceived BS as normative in men. The transmission of patriarchical-defined ideologies is tempered by the degree to which such ideologies espouse benevolent versus more overtly hostile attitudes toward women.     

Trust and trustworthiness in a sequential bargaining game

We use a two‐person extensive form bargaining game to explore individuals' trusting and reciprocal behavior and how those relate to their scores on a trust survey. In keeping with prior research, we find that the ‘self‐interested’ outcome is rejected by a majority of individuals. People who score high on the trust survey are both trusting and are also trustworthy, in that they reciprocate others' trust. But people with low‐trust scores often exhibit trust but are not trustworthy. These ‘inconsistent trusters’ seem to be interested in exploiting the trust and trustworthiness of others in increasing their own payoff. Copyright © 2003 John Wiley & Sons, Ltd.     

The influence of advance information on the response complexity effect in manual aiming movements

The relation between reaction time and the number of elements in a response has been shown to depend on whether simple or choice RT paradigms are employed. The purpose of the present study was to investigate whether advance information about the number of elements is the critical factor mediating the influence between reaction time and response elements. Participants performed aiming movements that varied in terms of the number of elements and movement amplitude. Prior to the stimulus, advance information was given about the number of elements and movement amplitude, movement amplitude only, number of elements only, or no information about the response. Reaction time and movement time to the first target increased as a function of number of elements only when the full response or the number of elements was specified in advance of the stimulus. The implication of these results for current models of motor programming and sequential control of aiming movements are discussed.     

Comparing derived and acquired acceleration profiles: 3-D optical electronic data analyses

Advances in technology in the last century have provided the opportunity to observe human behavior in one, two, and three dimensions with higher recording frequencies and greater spatial accuracy. Consequently, detailed analyses of individual trials and composite measures of multiple movement trajectories are possible. However, 3-D data have often been analyzed by performing independent analyses of the limb trajectory along each axis. Essentially, analyses of individual axes are often inappropriate as movement in each axis can contribute to the overall trajectory. Employing such methods can compound error throughout the analysis process. The purpose of this study was to determine appropriate post hoc and real-time 3-D optoelectronic data reduction procedures for manual aiming movements. Rapid goal-directed movements were recorded using an Optotrak and triaxial accelerometer. Data were separately subjected to second order Butterworth filters employing low-cut frequencies of 6-24 Hz in 2 Hz increments. Subsequently, acceleration profiles were derived by double differentiating the individual position profiles and then calculating the resultant acceleration profile. In addition, acceleration profiles were also calculated by finding the resultant position and the total distance traveled each frame prior to double differentiation. Root mean square error between the derived and acquired profiles was employed as our main dependent measure. Trajectories reduced with the total distance procedure produced the lowest root mean square error. The results are important for experimenters analyzing 3-D data post hoc and those implementing real-time manipulations.
