John Patrick Cooke Jr. A pre-test for throwing ability was administered to all subjects. Each subject threw a ball at a target from a distance of ten yards. Ten trials were allowed. After the pre—test a training program was con- ducted for six weeks. This program included the use of s»: :3 y 1- (3 :j "5 various passing and shooting drills equired the overhand throw. At the conclusion of the training period, a post- test for throwing ability was given. Scores were col- lected in the same manner as in the pre—test procedure. Test results were analyzed using the Kruskal-Wallis one-way analysis of variance by ranks statistical technique. There were no significant results indicated for differences between groups in throwing ability or in pre-test and post-test scores. ,rT\’A\'/‘V~fi 1 I " ‘ \ H .J..'1I"..LVK/.L.J “‘A‘ JUL m:'.-‘.

ON 00 4-»4— "A J:-‘ ‘ Statement of the Pr0blem Since many games and sports require the manipula- tion of various types of objects and implements involv— ing the arms and legs, the phenomenon of preferred laterality is an area of real concern in physical educa- tion. At the present time, the relationship of lateral dominance to motor ability has not been clearly estab- lished. If evidence can be presented establishing a clear cut connection between lateral douinance character- istics and motor abi‘ity, physical educators, psycholo- gists, and physiologists could utilize this information. in combined types of study in this area. O The purpose Oi this study was to investigate the relationship of hand-eye dominance in the learning of a complex motor skill in lacrosse. Importance and Need for the Study The game of lacrosse is the only game that enjoys a truly American heritage. Fro“ the time of th American ndian lacrosse has grown to the point where today it i I 8 ranked as the fastest growing sport in America.

Nature an Scppe of the Study ~ipated in this study. H (3 Fourteen subjects part They ranged in age from eig teen to twenty— —two yea old. All subjects were female students who were en— rolled in a lacrosse activity class in the Woman's Physical Education Department of Michigan State Uni- f- versity during the spring of 1909. The subjects were grouped according to hand- and eye-dominance combinations 1 J .and - right eye; .. into four preference groups: left left hand - left eye; rig ht hand - right eye; right hand - left eye. The subjects participated in a training program 9 q for six weeks which included training in skil and accuracy in the overhand throw. A pre—test and post-test were administered to com- pare the achievement of each group. Each subject was allowed ten throws at a target placed in front of m regulation lacrosse goal which was divided into areas of different point values. Results 0: the tests were compared with non-p ma etric statistics. PI) cf D 3“ (D (I) (‘1’ C KL Limitations c Limitations of the study included the following: I. The methods used for the determination of domi- a. nance characteristics were som what dated, and more recent inexpensive techniques were not available. The effect of having a male teacher instruct- ing a female activity cannot be determined. To insure the presence of left-handed indi- viduals within the population, eight subjects were requested to enroll in the activity. As the training program progressed, subjects from all dominance groups withdrew from the class, which severely limited the number of subjects within each dominance group. Definition of Terms Dominance.—-A preference for one hand, one eye, or one foot over the other in any given activity. Dextrality.--Pure right-sided dominance. Sinistrality.--Pure left-sided dominance. Homolaterality.--Dominance on the same side of the hand, eye, and foot. Contralaterality.--A quality of mixed domi- nance of hand, eye, and foot. Overhand throwing motion.-eA term to describe the action of each subject as she threw a ball lat a target. U1 ‘I The crosse was held at the throat in the dominant hand in a vertical position, with the pocket of the ng motion was FJ. crosse facing the target. The throw initiated by stepping forward on the opposite foot. Action of the hands and arms was a combined, coordinated on. To initiate the pushing H ing mot F l F_J pushing and pu motion, the upper hand_and arm were extended at the elbow and shoulder simultaneously. To initiate the pulling motion, the lower hand and arm were drawn from a position cf extension from the body to a position in which the lower hand on the crosse finally rested in the approximate area of the opposite axilla. n"r r17: 1"?

The phenomena of dominance, preferred lateralit or handedness appears to be one of th mysteries 0: human development. Walters stated, ”Alth ugh we are constructed bi later ally we function nilaterally and have a preference for one nand, one leg, and one eye. Theories of Dominance Development - 2 i.- ,. ” Early theories mentioned by Elau, ild retn,j a IT A " fl . ‘ ' ‘- 4.“ .“ ,a n. " A“ 1 way centered around developmental ideas and rel ed three major areas: anatomical factors, hereditary factors, and social influence factors. The early anatomical theories were concerned wi cerebral dominance within the fetus. One such theory reasoned that the fetus would develop a dominant brai hemisphere prior to birth. In this case if the left 0\ y, «a n4 th n brain was dominant the child would be born with righ - sided dominance. If the right brain was dominant the child would be born with a left-sided dominance.5 Another anatori cal theory, wr ich was supported, m inta ir led that the blood flow to one side of the brain reater than the bloOd flow to the other side of the 2 p) m 0'} ‘ rain hemisphere which received the greatest (3' O” ’3 Q) p. :3 F 3 ”8 amount of blood would become the dominant side. This theory was disproved by Cunningham in 1902. He found no significant difference in size between left and right carotid arteries. Blau in agreeing with Cunningham, stated that the hysiological di: erer .ces bethee the doninant and non— dominant sides as concerned with the brain and sensory organs were undetectable. Other anatomical tr eor ies were concerned with the center of gravity of tie body as determined by the place- 1 ' ,l 9 "‘ lo .' ‘—t,.h4— ‘ Lana +—'q‘ ment of the Viscera. slau indicated that this theory c<1 O '3 (D ()1 P C)” F.)

In this situation the blood pressure exerted by the right-side artery was greater, thus causing a greater incidence of ri ght -handedness within the popu- ll 12 . .. L lation. Blau indicated biat this theory could not be supported by any evidence either. Cr; 13 The last theory was developed by Jones, who stated that the length of the bones on the right side of reater than the same bone on w- a r ght-handed person was (V! the opposite side. This theory was inva Ni ated by Beeleyl)4 in l918. . 15 Iildreth fy }-Jc indicated that all efforts to ident a structural reason which would account for lateral dominance have failed. blau agreed and stated that congenital theories fififififi had little signili cance. A . Ba 17 h - 'V: 1 ‘_1 l8 .3 1: A ~ ‘ A“ 4-. Both au and hildretn indicated that there were theorists who held that handedness was determined by heredity. Blau‘9 found no consistent evidence that handedness followed familial tendencies. He further stated that in studies conducted Wl th twins, and in families with one or both parents being left-handed, there was no definite correlation between biological symmetry and lateral preference. The theory of social inf uence as a cause of determining handedness seemed to receive the strongest support from most authors. In this situation, handed- ness was determined by direct or indirect pressure placed .1 . ..,- 20 . -h .. on the child by SOCiety. hiidreth pOinted out this connection when she sta ‘ted that social convention had strong connections with laterality by establishing rules pertaining to how certain activities were to be done.

'— 92 DJ Palmer indicate similar findings in his study done in 1964. 13 Characteristics and Classification of Dominance Hand Dominance Hildreth commented on the difficulty of determining dominance when she stated, ”Laterality is a complex "53 514 feature of human structure and development. Irwin further established this difficulty when he found that dominance does not approximate a normal distribution. Palmer55 indicated that true dominance was diffi- cult to establish because of the influence of opposite? sided tendencies in the performance of any activity. This has caused many individuals to be incorrectly classified into a particular dominance group. Blau56 indicated difficulty in testing methods as one reason for inconsistency in hand-dominance determina— tion. Eye Dominance Blau57 indicated that the phenomena of occular dominance was first recognized by Humphrey in 1861. Since that time many investigations regarding occular dominance were undertaken in an effort to determine its distribution within the population, and to explore any means by which occular dominance could be determined. According to Hoerr and Olsen in Blakiston's New Gould Medical Dictionary, the dominant eye was defined 14 as, ”Tha eye which is unconsciously and preferentially CI) _ n3 Jo tions. (/1 9) E).

Oxendine 3 agreed that leIt-eye dominance was more common than left-hand dominance. They were supported by the work of Sinclair and Smith. Hildreth ’ indicated that eyedness could not be influenced by training. She also indicated that other investigators in this area could not supp rt any theories Crider indicated that there appeared to be no significant difference between the sexes in relation to which eye was dominant. This was in opposition to the findings that more males exhibited left-handedness than females. rm, - a r ' _ flf‘W‘fi“"q f‘ (‘_m'1V‘QV‘,"$e .. db -- _(_,' “CAR; \J ‘. ‘1’ \Jq~—..‘-.-\.~§AV —\ c o I‘Zhrl"“~- if:“"- (Kw U. ‘JK-- ....-.p~v..uv-¢ ..anq iJ\J..;_.pC. we A ..

Oxendine cited other methods utilized by other investigators which required timing and 5 im mulus machinery. Eye Dominance Eye dominance determination was another area in which there was considerable investigation, particularly in the area of psychology. One of the most important criterions for the determination of eye dominance was that the subject should not be aw re of the test purpose. This unconscious sighting was an essential element in preventing the subject from becoming confused during testing. Miles73 was the first author who indicated the need for unconscious sighting by the subject. His testing method utilized a tapered cone which the subject used to sight a visual target. He found that by having the sub— ject keep both eyes open while looking through the large end of the cone towar' the small end of the cone, the U " 1 c t Witd only Ofl 'e O testee was forced to si ()9 :3 Cf cf :1 (D (t ('D U) d O 0 LI C r (D U) cf (/2 :3 }_) (“f 3‘ < O) FS H eye. By repeating the ous visual targets, Miles was able to determine the preferred eye with ex— tremely high consistency. In this case, the preferred eye was considered to be the dominant eye. A {371'1 . - ._.:r.' 1 -.‘ _- ._ ,...- .. tulf substantiated this consistency using a similar type of cone. He found a reliability coefficient of 0.97 for measurement consistency. Other tests utilized the fingers and pencils as sighting objects. Crovitz75 maintained that this type of test was useful only as a screening device. To FI CI) detect real dominance with consistency, a more dif- ferentiated test lust be developed. 6 Cr er7 }._Jo developed one of the best test batteries concerning eye-dominance determ'nation. These particula items were developed over a period of ten years using (3‘ thousands of subjects. The attery had a reported relia— bility of 0.98 to 0.99. Crider also reported that sex, ha ndedness, intelligence, or visual acuity did not influence test resu‘ts. Further investigation into test— ing methodology failed to disclose other methods of equal consistency or ease of administration. a clear relationship between dominance and skill. Roth investiga ted the effects of hand and eye dominance as factors in motor ability. He indicated that of he four hand— eye domir -ance combinations pos— sible, the left -hand right—eye group proved to be superior in motor ability. Of the other groups, the right-hand, right—eye group was rated second; the right-hand, left— eye group was third; and the left-hand, left—eye group was rated fourth.

The major limitations dealing with skill achievement in any one individual [\l i were directly concerned with individual physiological makeup.

The four groups were designated as follows: left 29 hand - left eye; left hand - right eye; right hand - left eye; right hand - right eye. Since all subjects were unfamiliar with lacrosse and associated skills, two ten—minute training periods were given to the subjects during the first and second class periods to assure a meaningful measurement of their skill. Subjects were then tested for their abil— ity to throw a lacrosse ball at a target which repre— sented a lacrosse goal. After a six-week training program the subjects were retested with the same procedures and target. Description of Tests Determination of Hand Dominance The questionnaire technique, developed by Hull,l was used to establish hand dominance (see Appendix B). The questionnaire was a series of forty questions in which the subject was asked to indicate which hand she preferred to use to perform various common activities. If the subject could perform the skill equally well with either hand, she indicated this also. The dominant hand was determined from the question- naire by totaling the hand preferences the subject indi- cated the most number of times. x A).

If this line was extended it would divide the goal into two equal halves. Each subject was given instruction on the approach to the target. The left-handed subjects were instructed to throw from the right-hand side of the restraining lines and the right—handed subjects were instructed to throw from the left-hand side of the restraining lines. The following instructions were given to each subject in exactly the same way, Throw the ball at the target. You must stay within this area (indicating the right-hand or left—hand restraining area depending on the dominant hand of the subject). Run or trot to the target. Do not step over any of the lines. You do not want to hit the middle of the target. The subject was then told to pick up a regulation woman's lacrosse ball with her crosse and carry out the instructions. Replacement balls were immediately avail- able. This permitted the subjects to recover from their throw, pick up a new ball, trot to the target and throw again in a very short period of time. Each subject took ten shots at the goal from her respective restraining area. Successful or unsuccessful throws were determined and recorded.
