Rorschach indices for discriminating between two schizophrenic syndromes

Thinking disturbance and disorder of affects may be different in two subtypes of schizophrenia, the "florid" and the "withdrawal" syndromes. In Exner's approach to the Rorschach system, the diagnostic indicators of disordered thinking may point out large differences not only between schizophrenic and control subjects but also between different types of schizophrenics. The Rorschach protocols of 45 subjects (15 "florid" schizophrenics, 15 "withdrawn" schizophrenics, and 15 controls of the same age and education, matched by sex) were examined on several Exner indices. Compared with the control group, both schizophrenic types confirmed an impairment of perceptual accuracy and of reality testing as well as a reduced emotional control. Compared with the "withdrawn" group, the "florid" schizophrenic subjects showed significantly higher indices of poor perceptual functioning, of an inadequate organizational activity (more Whole and Z responses characterized by negative Form Quality) and greater disordered ideational production.     

Effects of observing competitive and violent versions of a sport

Males were randomly assigned to view either (1) a film clip featuring hockey fights or (2) a film of nonaggressive hockey action or (3) a no-film control condition after having first been angered or treated politely by an experimental confederate. The dependent variable was represented by a measure of aggressive mood and a behavioral measure of retaliatory aggression. Analyses revealed that both angered and nonangered subjects exhibited an increase in aggressive mood following exposure to the fight film. However, the analysis involving retaliatory aggression against the confederate yielded an anger x film interaction. While angered subjects were more aggressive than nonangered, only angered subjects retaliated against the confederate after viewing the fight film. The results were discussed in terms of Berkowitz’s (1974) aggressive cue theory. A version of this paper was presented at the meeting of the North American Society for the Sociology of Sport, Edmonton, Canada, November 1987.     

Influence of instructions and cognitive articulation on reducing the Müller-Lyer illusion with a repeated trial

The role of specific, suggestive instructions and of the subject's cognitive articulation in fostering modifications of Müller-Lyer illusory effect was studied. 60 female students were divided into four subgroups on the basis of (a) Witkin's GEFT scores and (b) instructions given to the subjects for the repeated trial. Analysis shows no statistically significant difference between the more and less articulated subjects on the first trial, for influence of both cognitive articulation and instructions or their interaction on the reduction of the illusion. Data are interpreted in terms of some theoretical explanations of geometrical illusions, such as 'centration theory' and 'assimilation theory'.     

Linking personal values to gender

Two studies were conducted to investigate the relation between personal values and aspects of gender. Study 1 used the Rokeach Value Survey (RVS) to examine the nature of stereotypes concerning the values of the “typical man” and the “typical woman”. Results supported the hypothesis that men are viewed as more likely to endorse agentic values, such as freedom and accomplishment, whereas women are viewed as more likely to endorse communal values, such as friendship and equality. Study 2 assessed men and women's possession of stereotypic sets of masculine and feminine values, using the RVS, and examined their relation to gender-related personality traits, gender-related interests and role behaviors, and global self-perceptions of masculinity and femininity. Masculine values were found to be significantly related to socially desirable masculine traits, socially undesirable masculine traits, masculine interests and a global self-concept of masculinity. Feminine values were shown to be significantly related to socially desirable feminine traits, feminine interests, feminine role behaviors, and a global self-concept of femininity. These results suggest that gender-linked personal values merit inclusion with traits, interests, role behaviors, and global self-concepts as part of an emerging multidimensional conception of gender characteristics.     

Management Selection in Australia: A Comparison with British and French Findings

The present study provided data on the cross-national use of management selection methods by collecting information from the Australian context. The data is compared with the British and French findings obtained by Shackleton and Newell (1991). A total of 254 companies (53.4%) responded to the survey. The overall pattern of results indicated that Australian management selection methods were closer to the British than to the French findings. Compared to previous Australian studies, the present data indicated that the main selection tools being used are unchanged. Some evidence was found that selection methods may differ within organizations comprising the private sector and between the private and public sector. The business sector made significantly greater use of cognitive testing and assessment centres compared to manufacturing, retail and government sectors. The government sector reported a significant difference in using two or three interviewers. It is proposed that, although surveys of this type have been useful as general reviews of the area, future research would benefit by collecting: (1) data on the specific measures used, (2) distinguishing between internal and external recruitment, (3) distinguishing between private and public sector recruitment, and (4) ensuring respondents have the same conceptual understanding of the selection methods covered by the survey.     

OBJECT SUBSTITUTION:

Abstract —Can four dots that surround, but do not touch, a target shape act as a mask to reduce target discriminability? Although existing theories of metacontrast and pattern masking say "no." we report this occurs when targets appear in unpredictable locations. In three experiments, a four-dot mask was compared with a standard metacontrast mask that surrounded the target. Although accuracy was predictably different for the two masks at a central display location in Experiment I. both masks had similar strong effects on accuracy in parafoveal locations. Experiment 2 revealed that both four-dot and metacontrast masking were insensitive to contour proximity in parafoveal display locations, and Experiment 3 showed that four-dot masking could occur even at a central location if attention was distributed among several targets. We propose that targets in unattended locations are coded with low spotiotemporal resolution, leaving them vulnerable to substitution by the four dots when attention is directed to them.     

Imagery and the autonomic nervous system: some methodological issues.

The present paper is concerned with the role played by image content in the mediation of autonomic nervous system (ANS) arousal. The minimum methodological requirements of such studies are described including controls for imaging, image content, and expectancy effects. Studies meeting these requirements are then reviewed. It is concluded that image content can be a significant modifier of ANS arousal and that this property is not restricted to images containing affective, e.g., phobic, content. These conclusions have relevance to research into techniques such as biofeedback, Transcendental Meditation, and progressive relaxation, where imagery many have a profound influence but where it has received little direct empirical attentiol.     

Luminous calibration of oscilloscopic displays

Procedures are described for adjusting the intensity of computer-driven oscilloscopic displays. The adjustment maintains a fixed intensity level on different occasions and equates the brightness of brief stimuli displayed for different durations (i.e., compensates for the effects of time-intensity reciprocity).     

珠心算过程的眼动和认知研究

本实验采用眼动技术和实验神经心理学的方法对珠心算的认知过程进行了实验研究。研究发现,在竖式运算时,接受过珠心算训练的儿童与没有接受过珠心算训练的儿童相比其眼动轨迹显著不同;神经心理实验的结果表明,训练组儿童在数学运算能力、数字记忆空间、注意力、大脑功能偏侧化等方面均与非训练组儿童有显著差别。
