Differences Among Cognitive-Processing Styles Groups on Personality Traits.
Differences among cognitive-processing style (hemispheric dominance) groups on personality traits were investigated. From responses to the Human Information Processing information processing: see data processing.

Survey, (HIPS), 17 students were identified using primarily the left hemispheric mode in processing information, 19 students the right hemispheric mode, and 19 students the integrated mode (both left and right hemispheric modes). Responses to the eight second-order 16 PF scales showed significant personality trait trait (trat)

The left hemispheric group had better leadership qualities than the right hemispheric group, more self-control than the right and integrated groups, and more anxiety than the integrated group.

The integrated hemispheric group showed more extraversion and independence and better leadership skills than the left hemispheric group, and more self-control and better adjustment and leadership skills than the right group.
Hemispheric dominance is often referred to as a cognitive style Cognitive style is a term used in cognitive psychology to describe the way individuals think, perceive and remember information, or their preferred approach to using such information to solve problems. of how one processes information based on differential capabilities of the left and right (cerebral cerebral /cer·e·bral/ (se-re´bral) (ser´e-bral) pertaining to the cerebrum.

Torrance (1982) defined hemisphericity "as the tendency for a person to rely more on one than the other cerebral hemisphere in processing information" (p. 29). According to according to

Zenhausern (1978) indicated that the hemispheric (cerebral) dominance is an appropriate classifying variable for studies. Beaumont et al. (1984) indicated that hemisphericity, as a characteristic, has been linked to personality, reasoning and thought, and abnormal states.
In a critical review, Beaumont et al. (1984) classified investigations on hemisphericity into four different groups: studies on lateral eye-movements, electro-physiological measures, questionnaires, and cognitive tasks. Numerous studies appear in each of these groups using relatively independent forms of investigation. Beaumont et al. (1984) questioned the validity of the forms used and the inferences drawn from them.
Regardless of the type of investigation researchers use, it is well known that people have different personality traits and that people think and process information differently. The question is whether hemisphericity is related to personality traits.
Nestor and Safer (1990) investigated whether hemisphericity was related to personality variables as measured by trait anxiety and the tendency to express versus inhibit emotions. Their subjects were 66 right-handed individuals who completed personality measures and were tested on two occasions with multiple measures of hemisphericity. Although some measures of hemisphericity showed moderate reliability, generally, they did not correlate with each other or with the measures of personality. However, the composite hemisphericity index indicated that the Right hemisphericity correlated cor·re·late

In an initial study, Charman (1979) examined the relationship between personality and hemispheric asymmetries with eight male psychology undergraduates of which four were classified as extraverts and four as introverts. He reported that (a) extraverts were significantly better than introverts in processing information, especially from the rapidly fading fading

His findings were interpreted to give further support to Dimond (1972), who "proposed the differences between extraverts and introverts for processing information on the ground that LH is better for verbal analytic processing whilst RH is better adapted for holistic processing" (p. 657).
In studying hemisphericity and creative functioning, Torrance (1982) noted a common notion that the right hemisphere is dominant in creative thinking. He pointed out that theories and models of the creative thinking processes have long been recognized as "the operation of two basic patterns of mental functioning. In one of these patterns, the logical, rational mind is dominant and in the other the intuitive, non-logical mind and other states of consciousness are dominant" (p. 29). In making reference to Osborn's (1964) study, Torrance explained the difference between critical intelligence as a specialized spe·cial·ize

Using the 16 PF Questionnaire, Karnes, Chauvin, and Trant (1984) investigated leadership traits (a personality characteristic) in students who were enrolled in a Honors College curriculum. They found significant differences on the Leadership Potential Scores of the 16 PF between students who held at least one elected leadership position and those who did not hold any leadership position. The elected leaders in the honors program were described as emotionally stable, mature, relaxed, unfrustrated and composed. However, these researchers did not study the hemisphericity of their students. The question raised here are leadership traits related to hemisphericity?

They reported differences on reaction time between the left- and right- hemispheric groups in processing sentences structured as True Negatives and False Negatives. The purpose of this study was to investigate whether there were significant differences in personality traits among hemisphericity (cognitive-processing styles) groups.
Subjects: Fifty-five students, enrolled in undergraduate psychology classes at a mid-western state university, were the subjects. They were identified as using primarily left, right, or integrated hemispheric mode in processing information from their responses to the Human Information Processing Survey, HIPS, (Torrance, Taggart & Taggart, 1984). In the group, 17 (8 men and 9 women, mean age = 25.5 years) used primarily the left hemispheric mode, 19 (6 men and 13 women, mean age = 19.7 years) used primarily the right hemispheric mode, and 19 (2 men and 17 women, mean age = 22.4 years) used the integrated mode, that is, they used both the left and right hemispheric modes in processing information. All subjects were right handed.
Instruments: Subjects responded to HIPS, and the 16 Personality Factor, 16 PF, (Cattell, Cattell & Cattell, 1978). The HIPS was used to identify the subjects' hemispheric mode of processing information. This inventory is a self-report, paper and pencil questionnaire consisting of 40 items. From the responses to HIPS one can infer an individual's hemispheric mode as being left, right, integrated (using both left and right), or mixed (using left or right). The procedure used to determine a subject's preferred strategy(ies) is done by converting the three HIPS scale raw scores (left, right, and integrated) to standard scores. If the individual's standard score is less than 120, that individual is classified as using a mixed (inconsistent) strategy (Taggart & Torrance, 1984). Subjects with mixed strategies were deleted Deleted

The researchers indicated that although creative thinking and problem solving required both right and left hemisphere functions, the data showed that the creativity measures correlated significantly and positively (from .30 to .73) with the Right Hemisphere Scales and significantly and negatively (from -.36 to -.68) with most of the Left Hemisphere Scales.
The 16 PF questionnaire is a self-report, paper and pencil inventory which lists characteristics one selects as traits that best describe oneself. All 16 PF scales could be used or the eight second-order factor scales derived from the 16 PF. Detailed descriptions of the 16 PF reliability and validity studies are provided in the manual. Krug and Johns (1986) cross-validated the eight second-order factors of the 16 PF from the responses provided by a large sample (N = 17,381) of men and women. The results were congruent con·gru·ent

Data showed significant differences on six of the eight scales: Extraversion [F(2, 53) = 6.90, p [is less than] .02]; Anxiety [F(2, 53) = 10.01, p [is less than] .01]; Independence [F(2, 53) = 4.79, p [is less than] .02]; Control [F(2, 53) = 24.83, p [is less than] .01 ]; Adjustment [F(2, 53) = 3.85, p [is less than] .02]; and Leadership [F(2, 53) = 10.59, p [is less than] .01]. The two scales in which the groups did not differ significantly were: Tough Poise [F(2, 53) = 0.98, p [is greater than] .05] and Creativity [F(2, 53) = 2.99, p [is greater than] .05]. The significant differences between the groups are summarized for each of the three groups as having reported higher scores than the other groups as follows.
The LEFT hemispheric group reported significantly higher scores than the: (a) right hemispheric group on the Leadership scale, (b) right and integrated groups on the Control scale, and (c) integrated group on the Anxiety scale. The RIGHT hemispheric group reported significantly higher scores than the: (a) left hemispheric group on the Extraversion, Anxiety and Independence scales, and (b) integrated group on the Anxiety scale. The INTEGRATED hemispheric group reported significantly higher scores than the: (a) left hemispheric group on Extraversion and Independence scales, (b) right hemispheric group on Control and Adjustment scales, and (c) left and right hemispheric groups on the Leadership scale.

Discussion and Conclusion
From the results of the analyses it can be concluded that there were some significant differences among the cognitive-processing (hemispheric dominance) style groups on personality traits. Stated simply, the left hemispheric group indicated having better self-control and leadership skills than the right hemispheric group and better self-control than the integrated group. The right hemispheric group showed more extraversion and independence than the left hemispheric group and higher anxiety than the integrated group. The integrated group were more socially out going and independent and showed better leadership skills than the left hemispheric group. The integrated group indicated having better self-control, adjustment and leadership skills than the right hemispheric group. It would appear that the integrated group has some personality traits which were found in both the left and right hemispheric groups. It might be a reason why they do better in various academic achievements (Gadzella, 1995; Wheatley et al., 1978)
There were no significant differences among the groups on the Tough Poise or Creativity scales. It might be that this Creativity scale measures characteristics found to be functions of both the left and right hemispheres. That is, it might be measuring what Torrance (1982) referred to as the left hemisphere focusing on critical thinking and the right hemisphere focusing on creative (original) thinking.
In previous studies (Charman, 1979; Dimond, 1972; Torrance, 1982), only the left and right hemispheric groups were investigated. In the present study, the integrated group (which uses both the left and right hemispheric modes in processing information) was also studied. Previous studies focused on personality characteristics such as extraverts and introverts (Charman 1979; Nestor & Safer, 1990), creativity (Torrance, 1982), and leadership (Karnes et al, 1984). In the present study (using the eight second-order factor scales) additional data on anxiety, independence, self-control, adjustment, and leadership were investigated. Although this study investigated some variables which were not previously studied, it was viewed as an exploratory one. It would be desirable to conduct similar studies with a larger number of subjects. The research studies could include variables such as gender, race, cultural background, intelligence and/or academic achievements, courses completed, interests, work and leadership experiences.
